Description

The invention relates to a holding device for a shelf on a shelf wall, a connecting element according to the preamble of claim 12, a shelf according to the preamble of claim 13, and the use of the holding device in a piece of furniture according to claim 16.

From the state of the art it is known to secure the shelves on shelves in the shelves by means of connecting elements in the form of protruding holding pins made of metal or plastic. The support pins of a shelf are inserted into holes on the insides of the shelf walls to a part, so that the protruding part of each retaining pin can serve as a support for the shelf. In order to adjust the height of a particular shelf, a plurality of holes for receiving retaining pins on the insides of the shelf walls are provided. In this way, the height of a shelf can be adjusted by first all the holding pins of a shelf at the same height are inserted into the corresponding holes of the shelf walls and then the shelf is placed on these retaining pins. The disadvantage of this, however, is that several steps are required to adjust the height of a shelf, which has a corresponding amount of time result. In addition, the aesthetic impression is reduced by the unused holes in the shelf walls, or there is a risk of injury when retaining pins from these holes protrude freely.

From the JP 2009 160033 A a holding device for a shelf on a shelf wall with a arranged on the shelf wall first connecting element and arranged in the shelf second connecting element is known. The second connecting element has an attracting to a holding element of the first connecting element acting magnet to move the holding element of the first connecting element magnetically along a pull-out direction from a retracted retracted position to an extended holding position for supporting the shelf to the shelf wall. By a arranged on the underside of the support member bevel the holding element is manually pressed in a lifting of the shelf in the retracted position. However, this can lead to tilting of the retaining element, whereby the release of the shelf is difficult. In addition, the slope of the retaining element in the retracted position forms a visually clear perceptible recess on the inside of the shelf wall, in which dirt can penetrate particularly easily, whereby the holding element can additionally jamming.

The object of the invention is therefore to enable a simple and quick release of the shelves of the shelf wall. In addition, a secure positioning of the shelves and an aesthetically pleasing shelf wall to be created. The holding device should also be used in furniture pieces for holding appropriate furniture parts.

This object is achieved by a holding device with the features of claim 1, a connecting element with the features of claim 12, a shelf with the features of claim 13 and the use of such a holding device in a piece of furniture according to claim 16. Advantageous embodiments of the invention are specified in the subclaims.

The holding device according to the invention for a shelf on a shelf wall is characterized in that the first connecting element comprises a housing and a spring element arranged in the housing, which holds the holding element in the retracted retracted position in the housing and on the one hand at an area with an enlarged cross section of Supporting element and on the other hand supported on an area with reduced cross section of the housing. By the spring element, the holding element is automatically moved to the retracted retracted position and held there. This ensures that the retaining element securely remains in the retracted position, as long as this does not affect a magnetic force through the second connecting element.

By supporting the spring element on the one hand on the region of enlarged cross section of the holding element and on the other hand on the area with reduced cross section of the housing a direct transfer of the spring force and thus a low Verklemmneigung and a space-saving design can be achieved.

Due to the magnetic attraction between the connecting elements, the holding element of the first connecting element is automatically extended into the holding position as soon as the connecting elements come into magnetically effective proximity, so that no additional working step is required for this purpose. If a plurality of first connecting elements are provided at different heights in the rack walls, then only those holding elements in the immediate vicinity of which there is a shelf with corresponding second connecting elements are in the extended holding position. The holding elements of the remaining first connecting elements are due to the action of the spring element in the retracted retracted position, which avoids injuries and allows an aesthetic impression of the inside of the shelf walls.

The spring element can be dimensioned so that in the retracted retracted position of the retaining element, the spring element is enstpannt. Only when the retaining element is moved out of this retreat position, the spring element is biased. This ensures that the magnetic force to move the retaining element can be extremely low. However, it is also possible to design the spring element so that it is biased in the retracted position of the holding element, resulting in a particularly good assurance of the holding element in this position. In addition, the spring element in addition to the usual spiral design made of metal or plastic and a foam with appropriate stretch or compressibility consist, for example, a hollow cylinder or a spiral of foam.

The region of increased cross-section of the retaining element prevents the retaining element unintentionally detached from the first connecting element and falling out of the shelf wall. Depending on the configuration of the retaining element, the region with increased cross-section can be arranged centrally or at a rear end opposite the protruding end of the retaining element. The holding element can be designed so that it protrudes in the extended holding position only on an inner side of the respective shelf wall. This is the case, for example, with the outer shelf walls of a shelf. Then, the area of the enlarged cross section is located at the rear end. However, if additional intermediate walls are arranged on a shelf between these outer shelf walls, corresponding first connecting elements are to be provided on both sides in these intermediate walls, but this can be achieved particularly advantageously by arranging the holding element of each first connecting element in a through hole in the intermediate wall, that it can protrude from both side surfaces of the intermediate wall. In this case, the region of the enlarged cross section is preferably arranged centrally on the holding element.

The region of reduced cross-section may preferably form a first guide section of the housing, the inner contour of which is slightly larger than an opposite outer contour of a holding section of the holding element, and a second guide section of the housing has an inner contour which is slightly larger than the opposite outer contour of the enlarged section Cross section of the retaining element. As a result, the guidance of the retaining element in the housing can be improved, since the risk of tilting is reduced by the two guide sections in the housing. In addition, an enlarged support surface is achieved, whereby particularly high weight forces of shelf with the second connecting element via the retaining element in the first connecting element and thus the shelf wall can be initiated.

As a slightly larger or smaller is to be understood in this sense that between the inner contour of the first guide portion and the opposite outer contour of the holding portion or between the inner contour of the second guide portion and the opposite outer contour of the region with an enlarged cross-section of the holding element usual for a guide Game is present, which is usually fractions of a millimeter. As a result of this slight play, in particular between the first guide section, which is arranged on a front end of the housing of the first connecting element facing the second connecting element, and the holding section of the retaining element, the penetration of dirt into the housing of the first connecting element is prevented. As a result, the leadership of the support member is not affected for a long time by accumulating in the housing dirt.

The cross-section of the inner contour of the first and / or second guide portion of the housing and the corresponding cross-section of the outer contour of the holding portion and the region of enlarged cross-section of the holding member may be formed in addition to circular also, for example, rectangular. This design of the retaining element allows a bearing surface which is larger than a round cross-section, whereby the surface pressure between the retaining element and the housing decreases. In addition, such a cross section is secured against rotation, so that a defined orientation of the retaining element is ensured on the housing.

In an advantageous embodiment, the housing between the first guide portion and the second guide portion having a first limiting element for defining the extended holding position of the holding element. The inner contour of the first delimiting element is larger than the inner contour of the first guide section, that is to say the area of reduced cross section of the housing, and smaller than the outer contour of the area of enlarged cross section of the holding element. If the holding element is pulled by the magnet in the direction of the second connecting element, the region of enlarged cross-section of the holding element comes to rest on the first limiting element, whereby the extended holding position of the holding element is structurally predetermined. Without this first limiting element, the spring element, which between the region of increased cross-section of the holding element and the area with is arranged in reduced cross-section of the housing and is supported there, be compressed in an inadmissible way over the maximum compression away, whereby the spring element would be damaged. Due to the defined extended holding position, the projection of the retaining element from the housing of the first connecting element is also exactly predetermined, which is advantageous for the connection to the second connecting element, as will be described below.

In a particularly preferred embodiment, the first limiting element may be formed as an annular web surrounding the spring element. This ring land may have a rectangular cross section or a round cross section. However, it is also possible for the first limiting element to be formed by a stop part, which extends only in sections in the circumferential direction, for the retaining element.

In order to define the retracted retraction position of the retaining element, in an advantageous embodiment the housing can have a second limiting element in the region of the second guide section at a rear end facing away from the second connecting element. The second limiting element can protrude inwards relative to the second guide section and thus form a rear stop for the retaining element in the retracted retracted position. This second limiting element may preferably be formed as a locking means with an elastic hook-shaped element in the form of a latching nose, whereby in particular the pre-assembly of the holding element is facilitated in the housing. For this purpose, provision may be made for the housing to have an opening at a rear end remote from the second connecting element, through which the holding element can be inserted into the housing and in particular into the first and second guide section of the housing. During pre-assembly, the hook-shaped element is pressed by the holding element elastically outwards until the holding element is arranged in the housing and the hook-shaped element springs back elastically.

In an advantageous embodiment, the holding element at a front end facing the shelf may have at an angle to the extension direction protruding locking element to fix the connecting elements positively against each other in the extended holding position by engaging behind a corresponding undercut on the shelf to be arranged in the second connecting element. The blocking element may also have the largest cross section in the region of its free end. In this way, the locking element in the extended holding position engage behind a corresponding undercut on the shelf and thus secure the first connecting element to the shelf. In addition to the magnetic attraction between the connecting elements so that additionally held by the blocking element, the first connecting element in the extended holding position, which increases security. In this case, the region of the free end of the retaining element is preferably that region which protrudes from the shelf wall in the extended holding position of the retaining element.

In a further advantageous embodiment, the second connection element can have a recess open towards the first connection element with an undercut for the positive reception of the blocking element. The undercut is advantageously oriented in the vertical direction, so that the blocking element is first inserted horizontally into the receptacle and then vertically upwards into the undercut. However, it is also possible to align the undercut at an acute angle to the horizontal, in principle, only an undercut in the horizontal direction is advantageous. Through this undercut, a positive connection of the second connecting element with the holding element and thus the first connecting element is achieved. This has the consequence that the shelf wall concerned can not deform laterally outward even at higher load on the shelves away from the shelves, whereby the load and the stability of the shelf are additionally increased.

The depth of the undercut, viewed in the extension direction of the retaining element, preferably corresponds to the projection of the locking element relative to the front, the second connecting element facing the end of the housing of the first connecting element in the extended holding position. In this case, the relationship applies that the depth of the undercut corresponds to the distance of the blocking element from the region of increased cross-section of the holding element minus the distance of the first limiting element from the front end of the housing.

It can also be provided that reduces the depth of the recess in the extension direction, starting from the undercut down. The reduction of the depth is preferably carried out in the vertical direction gradually down to zero, ie in particular without steps or edges. By this elongated undercut, the retaining element can be pressed in a removal of the shelf in the vertical direction by the reducing depth of the recess back into the retracted retracted position, whereby the effect of the spring element is supported.

The magnet can preferably be arranged in the second connecting element, in particular in a holder, adjacent to the undercut and held there in a positive and / or frictional engagement. Particularly advantageously, the magnet is positioned in the extended direction of the retaining element from the retracted retracted position to the extended holding position behind the undercut. This results in a particularly favorable magnetic force by the magnet on the holding element in the direction of the distinction. Particularly preferably, a stop on the second connecting element, in particular the holder, be provided between the magnet and the undercut. By the stop the minimum distance between the magnet and a arranged in the undercut blocking element and thus the maximum mutual magnetic attraction is precisely determined. In addition, the stop prevents that the magnet can move in the direction of the undercut, so that it remains reliably free undercut and also the magnet can not escape from the connecting element and in particular the holder.

The retaining element may be formed as a preferably elongated retaining pin and the spring element as a spiral extending around the retaining element compression spring. However, it is also possible to carry out the spring element as a tension spring, which is connected on the one hand with the holding element and on the other hand with the rear, the second connecting element remote from the end of the housing of the first connecting element in order to pull the retaining element in the retracted retracted position. But it is also possible to carry out the holding element, for example, as an elongated strip with a rectangular cross-section, whereby a particularly large-scale power transmission between the shelf and the shelf wall is made possible. Other configurations of the retaining element, for example with different cross sections or thicknesses are possible. In addition, the spring element may also have a rectangular cross-section corresponding to the holding element.

In addition, a connecting element is claimed, which is designed for placement in a shelf of a shelf and for holding interaction with a arranged in a shelf wall of the shelf further connection element, wherein it is open to the further connection element recess with an undercut for the positive reception of a locking element of having another connecting element. The connecting element may also preferably have the further features of the second connecting element of the described holding device.

According to the invention, a shelf has at least one holding device described above and below as well as at least two shelf walls and at least one shelf. In this case, the second connecting element of the holding device is arranged on a shelf wall facing one end of the shelves and the first connecting element of the holding device in the corresponding shelf wall opposite the second connecting element. In such a shelf, the adjustment of the height of a shelf can be done quickly and easily, since the holding elements of the respective first connecting element is automatically moved by the corresponding shelf in the extended holding position. The holding elements of the first fasteners not used for supporting a shelf are still in the retracted retracted position, whereby the risk of injury is reduced by protruding holding elements and the aesthetic impression is promoted.

It may be advantageous to arrange the first connecting element in the shelf wall such that the holding element is movable substantially in a horizontal plane between the holding position and the retracted position. In the case of the mostly vertical shelf walls, therefore, vertical recesses are to be provided in the shelf walls for receiving the connecting elements, which are easy to manufacture. In this case, the holding element of the first connecting element can also be moved without the influence of gravity. However, it may also be advantageous to use the force of gravity on the retaining element such that it is thereby held in the retracted retracted position. For this purpose, the first connecting element is to be arranged in the shelf wall, that the holding element is arranged higher in the holding position than in the retracted position. This is achieved in that the recess for the first connecting element relative to the shelf wall has an acute angle, which can be achieved for example by oblique holes.

In order to facilitate the positioning of the shelf on the two opposite shelf walls and to improve the stability of the shelf, it can also be provided that the shelf or the side walls of a shelf box, which are attached to the shelf at the lateral ends and parallel to extend the shelf walls, at least one additional magnetic element having, which corresponds in the installed position of the shelf or the shelf box between the shelf walls with at least one additional additional magnetic element in one of the shelf walls, in particular correspondingly positioned opposite each other, so that these magnetically acting attraction stand. When mounting such a shelf or such a shelf box, these additional magnetic elements come in magnetically effective proximity to each other and support the exact positioning of the shelf or the shelf box between the shelf walls by the increasingly strong with reducing the distance between them magnetic force. As a result, the shelf or the shelf box can be easily and quickly brought into its correct position between the shelf walls, whereby the connecting elements are positioned more easily to each other and thus the automatic extension of the holding elements is facilitated. In addition, these additional magnetic elements connect the shelf or the side walls of a shelf box with the shelf walls in the horizontal direction, whereby the cohesion of these components is enhanced.

Instead of directly opposing additional magnetic elements, it can also be provided that the additional magnetic elements in the shelf or the side walls of a shelf box and the shelf wall are vertically offset from each other so that the additional magnetic element in the shelf or the shelf box in the installed position of the shelf or the shelf box, so if the shelf or the shelf box are supported by the holding device, is arranged slightly above the other additional magnetic element in the shelf wall in the vertical direction. This results in a force acting in the vertical direction magnetic force between the additional magnetic elements, which causes an additional, acting in the vertical direction downward force on the shelf or the Regalbox against the holding device. As a result, the contact pressure of the shelf or the shelf box is increased to the holding device and in particular the holding element, which increases the stability of the shelf.

It can also be provided that the additional magnetic element in the shelf or the shelf box is formed integrally with the magnetically executed second connecting element. This combined magnetic element would then be advantageous to arrange so that the magnetic force acts substantially horizontally, so that both the additional additional magnetic element in the shelf wall and the first connecting element in magnetically effective range come, so that on the one hand between the combined magnetic element and the the first connecting member acts a sufficient force for extending the holding member of the first connecting member and on the other hand causes the magnetic force between the combined magnetic element and the further additional magnetic element, the positioning and pressing force described above. In order to minimize unwanted influence of the retaining element by the additional additional magnetic element in the shelf wall, the retaining element may be magnetically formed only at its outer, for example, cylindrical with a smaller diameter end. Alternatively or additionally, the additional additional magnetic element can also be made significantly smaller, in particular have a smaller diameter. This can also be used in the embodiments described above and below.

In order to position the shelf or the shelf box in a unique, predetermined position between the shelf walls easier and to avoid incorrect positioning can, for. B. that the shelf or the shelf box are installed rotated 180 ° about the vertical axis, it can be provided that, for example, the additional magnetic elements in the shelf or the shelf box and accordingly in the shelf walls in a side view of the shelf or the shelf box are arranged asymmetrically or only one side corresponding magnetic elements in the shelf or the shelf box and the shelf wall are arranged. In case of incorrect installation of the shelf or the shelf box between the shelf walls then acts due to the large distance between the corresponding additional magnetic elements no sufficient magnetic force, whereupon the user detects the missing positioning aid and repositioning. In addition to this installation aid, the holding devices and the additional magnets can also be installed rotationally symmetrical. This means that the first connecting elements are arranged offset on one side of the shelf with the corresponding second connecting elements in the shelf wall in a longitudinal direction of the shelf adjacent to the shelf wall of the shelf and the first connecting elements on the other side of the shelf with the corresponding second connecting elements in the opposite shelf wall are arranged offset in the opposite direction by the same distance. In the plan view of a shelf, therefore, the first connecting elements and thus also the corresponding second connecting elements, starting from an arrangement in which the connecting elements are arranged symmetrically to a central axis arranged in the longitudinal direction of the shelf, on both sides by the same distance, but in opposite Directions along the end faces of the shelf moved. Such a trained shelf is so far rotationally symmetric, as that although the first connecting elements to a center between the End sides of the shelf arranged transverse axis are not symmetrical, with a rotation of a shelf around a vertical axis by 180 °, the positioning of the connecting elements is identical, so that even in this orientation a mounting of the shelf in the shelf is possible.

The reason for this rotationally symmetrical arrangement of the connecting elements is that the first connecting elements can extend far into the shelf wall, however, especially in partitions of a shelf in which corresponding shelves are arranged on both sides, the wall thickness of the partition wall can be too low to arrange two first connecting means for each side of the partition coaxially exactly behind one another. In order to allow a planar arrangement of the shelves on both sides of the partition at the same height, the first connecting elements on one side of the partition opposite the first connecting elements on the other side of the partition as described can be offset uniformly rotationally symmetrical. The corresponding second connecting elements on the corresponding side of the partition and the opposite shelf wall are then also arranged offset uniformly rotationally symmetrical.

In order to additionally facilitate the actuation of the retaining element, the retaining element may consist of a material which is light but nevertheless magnetically active in comparison to steel and / or hollow or perforated. As a result, the inertia of the holding element can be reduced without thereby appreciably reducing the magnetic force on the holding element. So it is sufficient already a lower magnetic force to bring the holding element in its extended holding position. The holding element can also be formed as a whole or only partially, for example only the tip of the holding element, as a magnet. Such a holding element can be produced for example as a magnet by injection molding. In addition, a corresponding bar magnet can be inserted or pressed into an inner recess of a hollow holding element. If the material of the holding element or at least of the blocking element consists of a magnetic active material, a magnet, for example a disc magnet, can be arranged at the rear region with an enlarged cross-section of the holding element, whereby the remaining part and in particular also the blocking element is magnetized. With such a magnetized holding element can be dispensed with in an advantageous manner to the above-described additional magnets, in which case, however, in addition to the parallel arrangement, the central axis of the magnet in the holder or the second connecting element is offset vertically to the central axis of the holding element so that the central axis of the magnet is higher than the center axis of the holding member to ensure a vertical contact pressure.

According to the invention, it is also provided to use the described holding device for holding corresponding furniture parts in a piece of furniture. These furniture parts can be trays of any kind, for example, floors in a desk, in a cabinet to a slatted base in a bed frame.

1 shows a sectional view of a first embodiment of the holding device according to the invention 1 inserted in a shelf 2 and an adjacent shelf wall 3 a partially shown shelf. This relative position of the shelf 2 to the shelf wall 3 represents the situation in which the shelf 2 was inserted into the shelf and through the holding device 1 on the shelf wall 3 is held. The holding device according to the invention 1 comprises a first connecting element 4 and a second connecting element 5 , The second connection element 5 is designed as a magnet and from below to the shelf wall 3 facing the end of the shelf 2 flush in a recess in the shelf 2 used.

In the shelf wall 3 is in a bore formed as a lateral recess 6 the first connection element 4 arranged. This comprises a holding element 7 in the form of an elongated retaining pin, designed as a spiral spring spring element 8th and a housing 9 in which the retaining element 7 and the spring element 8th are arranged. The holding element 7 consists wholly or partly of a magnetically active, that is attractable material, eg. As steel, iron, etc. The housing 9 is designed as a socket in which the holding element 7 recorded and conducted. For fastening the housing 9 in the shelf wall 3 is provided, this via an adhesive connection, a press connection, a threaded connection or the like flush with the side surface of the shelf wall 3 in the recess 6 to fix.

The holding element 7 is relative to the housing 9 movably formed. The recess 6 corresponds in depth preferably at least the length of the retaining element 7 so that the retaining element 7 in a retracted retraction position with its outer, in the direction of the shelf 2 pointing end flush with the side surface of the shelf wall 3 concludes, definitely not beyond it. Since no part protrudes in this retreat position and the impression of a closed side surface of the shelf wall 3 there is no risk of injury and there is an aesthetically pleasing uninterrupted side surface of the shelf wall 3 , Possibly. can the case 9 in the direction of the shelf 2 pointing end also have a flange in the form of a radially outwardly extending circumferential annular ridge. This flange forms a stop when pressing the housing 9 in the shelf wall 3 , The flange can be flush with the outside of the shelf wall 3 conclude or be recessed against this, in the latter case, the holding element 7 at its front shelf 2 facing end has an area with an enlarged cross section, which preferably corresponds to the cross section of the flange. This is in the retracted retracted position of the retaining element 7 visually appealing only one visible edge is present and also is particularly good penetration of dirt into the housing 9 prevented.

The housing 9 has a first guide section 10 , which at one the second connecting element 5 facing the end of the housing 9 is formed, and a second guide portion 11 , which adjoins the first guide section 10 connects, on. At the in the recess 6 indicating end of the retaining element 7 is an area with an enlarged cross section 12 formed, to which a holding section 13 followed. The guide sections 10 . 11 , the area with enlarged cross-section 12 and the holding section 13 each have a constant cross-section over the length, but also conical or continuously variable cross-sections are conceivable. Here is the diameter of the area with an enlarged cross section 12 larger than the inner diameter of the first guide portion 10 so that the retaining element 7 not completely through the first guide section 10 in the direction of the second connecting element 5 pass through and out of the case 9 can fall out.

Between the first guide section 10 of the housing 9 and the area of enlarged cross-section 12 of the holding element 7 is designed as a spiral spring spring element 8th around the retaining element 7 arranged around. This is the spring element 8th biased with one end to the region of enlarged cross-section 12 of the holding element 7 and at the other end on the first guide portion 10 of the housing 9 on, so that the retaining element 7 of the first connecting element 4 is pressed in the retracted retracted position.

Due to the proximity of the magnet formed as a second connecting element 5 to the first connection element 4 However, a magnetic force acts between the connecting elements 4 . 5 , which is greater than the restraining force by the spring element 8th so that the retaining element 7 pulled out in the extension X and that is in the extended holding position. In this holding position, the holding element 7 by the magnet of the second connecting element 5 against the action of the spring element 8th subjected to, whereby the retaining element 7 from the side surface of the shelves 3 protrudes and a support for the shelf 2 forms.

The housing 9 of the first connecting element 4 extends over the entire length of the recess 6 in the shelf wall 3 , The first guide section 10 In this case, it has an inner contour, which essentially corresponds to the outer contour of the opposite holding section 13 of the holding element 7 equivalent. The second guide portion has a larger inner contour on the other hand, which is substantially the outer contour of the opposite region with an enlarged cross-section 12 of the holding element 7 equivalent. Essentially in this context means that in each case there is a slight gap between the opposite sections, which is a free relative movement between the holding element 7 and the housing 9 allows. This will ensure that the case 9 the holding element 7 can record and lead.

Due to the tight dimensional tolerances with which the housing 9 can be made, and a suitable choice of material for the housing 9 , For example, plastic or metal, which compared to a example of wood materials existing shelf wall 3 allows significantly more precise manufacturing and low friction coefficients, can tilt the retaining element 7 reliably prevents and the actuation of the retaining element 7 be further improved between the retracted retracted position and the extended stop position.

The housing 9 is formed as a cylindrical sleeve, wherein the second guide portion 11 with the enlarged inner contour, here so inner diameter, through a blind hole and the first guide section 10 is formed by the blind hole bottom with a bore with a smaller inner contour, here so inner diameter of the bore. The outer contour of the housing 9 is cylindrical and substantially corresponds to the inner contour of the recess 6 in the shelf wall 3 , For fastening the housing 9 in the shelf wall 3 is provided, that via an adhesive connection, a press connection, a threaded connection or the like flush with the side surface of the shelf wall 3 in the recess 6 to fix.

Instead of the circular contours or cross sections, other contours or cross sections may advantageously also be used, for example polygonal, in particular triangular, quadrangular, hexagonal or octagonal internal and external contours.

In 2 is a sectional view of a second embodiment of the holding device according to the invention 1 shown. In this case, in contrast to the first embodiment, the second connecting means 5 next to a magnet 14 a bracket 15 in which the magnet 14 is arranged. The second connection element 5 is at a lower, the shelf wall 3 facing edge of the shelf 2 arranged. The holder 15 of the second connecting element 5 has a laterally in the direction of the first connecting element 4 and downwardly open recess 16 with an undercut 17 on. The undercut 17 extends from the recess 16 in a vertical direction upwards. However, it is also possible, the second connecting element 5 in the shelf wall 3 facing end side of the shelf 2 to be arranged, wherein the corresponding recess in the shelf can be incorporated either directly into the front page, which in particular the bottom of the shelf 2 undergoes no processing and therefore is a visually appealing, or as in 2 shown the corresponding recess can be incorporated from the bottom of the shelf in the front page, but the recess extends vertically further upward, so that the underside of the second connecting element 5 can be provided with a corresponding cover, which is flush with the bottom of the shelf 2 completes and forms a visually appealing underside. This cover has a recess, which the recess 16 continues in the vertical direction, so that the retaining element 7 unhindered in the recess 16 can retract.

Notwithstanding the following illustrations, the holder 15 also a security element 18 on, by means of which the magnet 14 in a recording 19 in the holder 15 is fixed. The fuse element 18 is designed as an elastic hook-shaped locking lug, which is a simple pre-assembly of the magnet 14 in the holder 15 allows. Will the magnet 14 during the pre-assembly of the second connecting element 5 through an opening in the holder 15 in the recording 19 inserted, the fuse element 18 laterally deflected upward elastically and then springs when the magnet 14 completely in the recording 19 the holder 15 is arranged, back to the magnet 14 positive fit in the receptacle 19 to fix. This will be a pre-assembly of the magnet 14 in the holder 15 allows and prevents the magnet 14 during storage of the second connecting element 5 or when mounting on the shelf 2 from the holder 15 solves.

In addition to slightly different proportions, the holding element differs 7 from the in 1 also shown embodiment in that the holding element 7 at a front, the second connecting element 5 facing end at an angle to the extension direction X of the holding element 7 protruding blocking element 20 having. The blocking element 20 is perpendicular to the extension direction X of the holding element 7 oriented, thus forms a vertical projection to in the extended holding position by engaging behind the undercut 17 a releasable positive connection with the second connecting element 5 to enable. Through this rear grip of the retaining element 7 on the shelf 2 is an unintentional movement of the retaining element 7 prevented in the extended holding position and thus a positive, particularly secure fixation of the retaining element 7 achieved in this position. In particular, an uncontrolled release of the shelf 2 from the shelf wall 3 is thus reliably prevented, which increases the horizontal stability.

The outer diameter of the barrier element 20 may, in an embodiment not shown, at least the outer diameter of the housing 9 be equal or greater than this. Will in this case the case 9 so in the shelf wall 3 sunk that locking element 20 in the retracted position of the holding element 7 flush with the side surface of the shelf wall 3 closes, obscures the blocking element 20 the housing 9 , resulting in an aesthetically pleasing side surface of the shelf wall 3 gives and the penetration of dirt into the first connecting element 4 reliably prevented.

In addition, by a likewise not shown embodiment of the locking element 20 together with the undercut 17 an additional force on the retaining element 7 in the direction of the extended holding position, ie in the extension direction X, be effected. These are the contact surfaces between the blocking element 20 and the undercut 17 form at an acute angle to a horizontal plane, so that by the weight of the shelf 2 the holding element 7 is pulled into the extended stop position. This allows the required magnetic force of the magnet 14 of the second connecting element 5 be chosen lower, and it is still a secure mounting of the shelf 2 on the shelf wall 3 reached. Indicates the blocking element 20 In addition, also a rectangular cross-section, resulting in an enlarged support surface relative to the shelf 2 and thus also a higher additional pull-out force on the holding element 7 , This is fully on the application EP 2 944 224 Reference is made and included their disclosure.

Opposite the in 1 embodiment shown, the housing 9 of the first connecting element 4 between the first guide section 10 and the second guide portion 11 additionally a first limiting element 21 in the form of a ring land on which the movement of the retaining element 7 in the extension direction X, ie in the direction of the retracted retracted position in the extended holding position limited. In the extended holding position is the area with an enlarged cross-section 12 of the holding element 7 on this boundary element 21 at. The inner contour of the first limiting element 21 is greater than the inner contour of the first guide section 10 , So the area with reduced cross-section of the housing 9 , and smaller than the outer contour of the area with enlarged cross-section 12 of the holding element 7 , The inner contour of the limiting element 21 is formed such that a gap between the limiting element 21 and the holding section 13 is formed, in which the spring element 8th is arranged. A contact surface for the spring element 8th at the first guide portion 10 is from a stop surface on the first limiting element 21 for the area with enlarged cross-section 12 of the holding element 7 in the extension direction X of the holding element 7 so spaced that the distance is slightly greater than the length of the maximum compressed spring element 8th is. Without this first limiting element 21 could be the spring element 8th be compressed in an inadmissible way beyond the maximum compression time, whereby the spring element 8th would be damaged. In addition, by the first limiting element 21 also the projection of the retaining element 7 and in particular the blocking element 20 out of the case 9 in the direction of the second connecting element 5 specified exactly and reproducibly.

Furthermore, the housing has 9 of the first connecting element 4 in the region of the second guide section 11 at a second connecting element 5 facing away from the rear end of a second limiting element 22 on. The second boundary element 22 is opposite the second guide section 11 inward and thus forms a rear stop for the retaining element 7 in the retracted retreat position. The second boundary element 22 is designed as a latching nose with an elastic hook-shaped element, whereby in particular the pre-assembly of the holding element 7 in the case 9 is relieved. Through an opening in the housing 9 at a second connecting element 5 facing away from the rear end, the retaining element 7 in the case 9 and especially in the leadership section 10 . 11 of the housing 9 be inserted. During pre-assembly, the locking lug is replaced by the retaining element 7 pressed elastically outwards until the retaining element 7 in the case 9 is arranged and the locking lug springs back elastically.

In the in 2 shown position of the shelf 2 to the shelf wall 3 is the shelf 2 still so far from the shelf wall 3 removes that no or only a very small magnetic force from the magnet 14 of the second connecting element 5 on the holding element 7 of first connecting element 4 he follows. Because of the spring element 8th on the holding element 7 acting restoring force in the retracted retracted position is significantly larger, the holding element 7 held in the retracted retreat position. The spring element 8th can also be dimensioned so that in the retracted retraction position no spring force on the retaining element 7 acts, so no bias is applied. In this case, the magnet in the illustrated arrangement is still too far away, so that no magnetic force acts.

At the in 3 shown sectional view through the holding device 1 is the shelf 2 closer to the shelf wall 3 arranged as at the in 2 shown arrangement. In this intermediate step for fixing the shelf 2 on the shelf wall 3 is the shelf 2 not at all or only slightly spaced from the shelf wall, however, is the shelf with the second connecting element 5 in the vertical direction slightly higher than the first connecting element 4 positioned. In this arrangement, the magnetic force of the magnet causes 14 in that the retaining element 7 against the force of the spring element 8th is moved from the retracted retracted position in the direction of the extended holding position. In 3 is the retaining element 7 of the first connecting element 4 moved to a part in the direction of the extended holding position, so that in particular the blocking element 20 from the side surface of the shelf wall 3 protrudes.

The second connection element 5 is opposite to the first connecting element 4 so arranged that the recess 16 in the holder 15 the blocking element 20 of the holding element 7 in the extension direction X is opposite and thus the blocking element 20 in the recess 16 can be drawn in. By the extension X behind the recess 16 in the holder 15 arranged magnets 14 becomes the retaining element 7 rectilinear and at a short distance magnetic in the direction of the recess 16 drawn. In order to ensure easy mounting of the shelves on the shelf wall by means of the holding devices, all forces, ie in particular the spring force of the spring element 8th and the magnetic force of the magnet 14 , So on the distances, in particular the installation depth of the magnet 14 on the shelf 2 as well as the size of the recess 16 in the horizontal direction, adjust that even with still remaining slight distance of the shelf 2 from the shelf wall 3 in a conventional assembly of the shelf 2 From above, the spring force so early through the magnet 14 is overcome that the holding element 7 is pulled out of its retreat position before entering the undercut 17 can drive. This results in no jamming of the elements, but it is a pleasant and frictionless assembly process allows.

In 4 is a sectional view through the holding device 1 shown in an arrangement in which the shelf 2 by means of the holding device 1 positively connected to the shelf wall. The shelf 2 lies with his to the shelf wall 3 facing side surface on the shelf wall 3 at. Opposite the in 3 The arrangement shown was the shelf 2 together with the second connecting element 5 also relative to the shelf wall 3 with the first connecting element 4 moved down, leaving the blocking element 20 with the vertically upstanding part in the undercut 17 in the holder 15 engages and thus the fasteners 4 . 5 are positively fixed against each other in the horizontal direction.

In this extended holding position of the holding element 7 lies the area with an enlarged cross-section 12 directly on the first limiting element 21 at. The spring element 8th is in the gap between the first limiting element 21 and the holding section 13 of the holding element 7 arranged and compressed. To a substantially backlash-free attachment of the shelf 2 on the shelf wall 3 to allow, stands the blocking element 20 exactly as far over the case 9 and thus the shelf wall 3 in the direction of the shelf 2 that is the blocking element 20 in the undercut 17 fits. This is achieved by taking the depth of the undercut 17 in the extension X the distance of the locking element 20 from the area of enlarged cross-section 12 minus the distance of the first limiting element 21 from the front, the shelf 2 facing the end of the housing 9 equivalent.

To make a flush closure of the case to the front, the shelf 2 facing end in the retracted retracted position of the retaining element 7 to allow, in particular to ingress of dirt into the housing 9 To prevent, it can be provided that the cross section of the blocking element 20 at its the second connecting element 5 facing free end of the cross section of the first guide portion 10 in the area of the front, the second connecting element 5 facing the end of the housing 9 equivalent. As a result, in the retracted retracted position the housing 9 in the area of the first guide section 10 tightly closed. As the illustration in 4 it can be seen, the holding section 13 be dimensioned so that in the extended holding position shown, the area of the holding section 13 , which at the front end of the housing 9 abuts, the same cross-section as the first guide portion 10 having. In order to is also in the extended holding position of the holding element 7 prevents penetration of dirt through the clean completion.

In addition, the length of the holding element corresponds 7 , So the distance of the free end of the locking element 20 from the rear end of the enlarged cross-section area 12 , the distance of the second boundary element 22 from the front end of the housing 9 , This ensures that the blocking element 20 opposite the housing 9 in the retracted retracted position does not protrude, but flush with the front end of the housing 9 concludes. As well as the case 9 so in the shelf wall 3 is inserted, that it is flush with the front end with the inside of the shelf wall, which is particularly easy mounting technology is optically a particularly appealing shelf wall 3 allows, which does not support shelves 2 used first fasteners 4 flush with the shelf wall and form a visually uniform surface. In addition, there is no risk of injury by projecting from the shelf wall projections. Should the blocking element 20 as described alternatively the the second connecting element 5 facing end face of the housing 9 Cover, is for flush completion of the first connection element 4 with the shelf wall 3 Provide that the length of the retaining element 7 , So the distance of the free end of the locking element 20 from the rear end of the enlarged cross-section area 12 , the distance of the second boundary element 22 from the inside of the shelf wall 3 matches and the case 9 correspondingly shorter and in the shelf wall 3 is formed sunk.

Further details and particular embodiments of the components of the holding device 1 are the following individual representations in the 5 to 11 refer to.

In 5 is a perspective view of an exempt housing 9 of the first connecting element 4 shown. The housing 9 is formed as a substantially cylindrical socket. In this view, on the front, the second connecting element 5 facing the end of the housing 9 is the first guide section 10 to be taken, which is directly to the front end of the housing 9 connects and is formed by a circular recess. At the rear end of the housing 9 is the second boundary element 22 arranged with the latch. The detent has an elastic web, which allows rebounding of the detent in the radial direction. On the outside, the housing faces 9 serrated ribs 23 on, which towards the front end of the housing 9 demonstrate. These ribs 23 increase when the housing is pressed in 9 in the corresponding recess 6 in the shelf wall 3 the friction and thus the holding force on the housing 9 , In addition, the ribs allow 23 In addition to the increased friction and a positive connection as a pull-out protection of the housing 9 especially against the installation direction. Instead of the ribs 23 can also other holding means, in particular a thread on the outside of the housing 9 be provided. By means of a special key, which, for example, on the holding element 7 or the case 9 attacks, the first connection element 4 into the recess 6 screwed into the shelf wall and fixed it. A non-rotating connection of the retaining element 7 with the housing 9 can over the longitudinal groove 24 be achieved. The special key may comprise a magnet, with the aid of which the retaining element 7 is pulled into the extended holding position and thus can be used by the key.

Furthermore, the housing has a longitudinal groove 24 in the first guide section 10 on which extends starting from the front end of the housing 9 in the longitudinal direction of the housing 9 to the second limiting element 22 extends. As in particular the longitudinal section through the housing 9 in 6 can be seen, runs the longitudinal groove 24 both through the first guide section 10 , as well as the subsequent first limiting element 21 , Through this longitudinal groove 24 which is not absolutely necessary, on the one hand, the production of the second limiting element 22 relieved, but this longitudinal groove 24 as a guide and anti-rotation for the retaining element 7 be used. For this purpose, on the holding element 7 an unillustrated, projecting in the radial direction guide part may be provided which in the longitudinal groove 24 engages and is guided there. This can ensure that the retaining element 7 at a translational displacement relative to the housing 9 not twisted. This is particularly advantageous if the blocking element 20 of the holding element 7 is not rotationally symmetrical, but for example only protrudes vertically upwards and thus the exact positioning of the locking element 20 to the second connecting element 5 necessary is.

Again 6 can also be seen, forms the second limiting element 22 directly a radially outer surface of the housing 9 in which other than on the other cylindrical outer surface of the housing 9 no ribs 24 are provided. Regardless of whether on the radial outer side of the second limiting element 22 such ribs are arranged or not, this outside of the second limiting element is located 22 in the recess 6 on the shelf wall 3 on, so that a radial movement of the latch formed as a second limiting element 22 is prevented. This ensures that in the installation position of the housing 9 in the shelf wall 3 the second boundary element 22 can not deform elastically, creating a reproducible and durable stop for the retaining element 7 is ensured in the retracted retracted position. Alternatively, the corresponding outer side of the second limiting element 22 also a minimal clearance to the recess 6 in the shelf wall 3 have (as well as designed as an elastic locking lug fuse element 18 the holder 15 to the shelf 2 ), wherein the game against the engagement length of the limiting element 22 (and the fuse element 18 ) is dimensioned smaller, to prevent accidental release of the retaining element 7 (and the magnet 14 ) to prevent.

In 7 is a side view of the released retaining element 7 shown. At the front, the second connecting element 5 facing end is the blocking element 20 arranged. The blocking element 20 is by a circular, in the radial direction against a subsequent annular groove 25 formed annular ridge, the outer contour of the outer contour of the annular groove 25 subsequent holding section 13 equivalent. To the holding section 13 the area borders with an enlarged cross-section 12 which is at the rear end of the holding element 7 is arranged. The area with enlarged cross-section 12 is formed by an annular web whose outer contour is greater than the outer contour of the holding portion 13 is.

The holding element 7 has a round cross section, wherein also other cross sections, in particular angular cross sections, in particular in the blocking element 20 and the holding section 13 are conceivable to the above-described rotation of the retaining element 7 in the case 9 in an alternative way. In this case, then at least the first guide section 10 of the housing 9 to execute with a corresponding rectangular cross-section. By a rectangular cross section, in which a lower contact surface of the first guide section 10 runs horizontally, a particularly large contact surface for the holding element 7 or the holding section 13 allows, whereby the surface pressure decreases and high weight forces from the shelf 2 in the shelf wall 3 are transferable.

8th shows a front view of the exempted second connecting element 5 from the perspective of the first connector 4 , Like the case 9 of the first connecting element 4 also has the bracket 15 lateral ribs 26 which are directed downwards in this example. This is because of this holder 15 designed to be vertically upwards in a corresponding recess in a shelf 2 , as in one of the 2 to 4 shown to be pressed in. Through the ribs 26 also increases the friction and thus the holding force of the holder 15 in the shelf 2 , Like the ribs 23 on the housing 9 allow the ribs 26 In addition, a positive connection as a pull-out protection in particular contrary to the installation direction.

At the flat end of the bracket shown 15 is a recess 16 formed, which tapers towards the top. The upper area of the recess 16 is slightly larger than the cross section of the holding element 7 in the area of the annular groove 25 , Laterally, the upper area of the recess 16 limited to cheeks, but which can be significantly smaller or larger or with different contour than shown. On the cheeks can be completely dispensed with, so that only a circular bottom in the upper part of the recess 16 is available. It is essential that the timing of the retraction of the retaining element is ensured in coordination with the other components. Also is in 8th the magnet 14 shown, which is directly behind the recess 16 in the holder 15 is arranged.

In again 9 shown sectional view of the second connecting element 5 along the section line AA of 8th can be seen, is in the extension X of the support member 7 behind the recess 16 , in particular behind the tapered upper portion of the recess 16 , an undercut 17 arranged. This undercut 17 extends vertically upwards and is for receiving the locking element 20 educated. The magnet 14 is through an opening on one of the recess 16 opposite back of the bracket 15 in the recording 19 the holder 15 used and arranged in the extension direction X directly behind the undercut. At the back of the bracket 15 are also ribs 26 arranged.

By also designed as an elastic locking lug fuse element 18 becomes the magnet 14 in the holder 15 held. As with the case 9 of the first connecting element 4 also forms the securing element 18 an outer surface of the holder 15 , which are on the shelf 2 comes to rest, allowing a release of the latch at one in the shelf 2 built-in second connecting element 5 is prevented.

10 shows a front view of an alternative second connecting element 5 , Unlike the in 8th embodiment shown has the holder 15 an elongated, vertically extending shape. The recess 16 also extends from an upper tapered region in the upper part of the holder 15 in vertical downward direction substantially to the lower end of the bracket 15 , The magnet 14 is in the upper part of the bracket 15 , again behind the tapered area of the recess 16 arranged. Although not shown, the alternative embodiment of the second connecting element shown may be 5 as well as in the 8th and 9 shown second connecting element 5 on the outside ribs 26 or the like, to the friction and thus the holding force in the shelf 2 to increase. This alternative second connecting element 5 can as well as the second connecting element described above 5 vertically in the front of the shelf 2 be arranged, the shelf 2 then have to have a corresponding strength. Around the alternative second connecting element shown 5 can also be integrated into a shelf with visually appealing low strength, the alternative second connecting element 5 also horizontally or at an acute angle to the horizontal aligned with the shelf 2 be attached. In this case, the assembly and release movement of the shelf is different than in the purely vertical movement of the second connecting element described above 5 a combination of horizontal and vertical or a purely horizontal movement. This alternative second connecting element 5 can then by means of the ribs already described or screws in a corresponding recess in the front side of the shelf 2 be attached. For this purpose, the alternative second connecting element 5 preferably be made slightly longer, so that still two screw holes can be placed. This is especially the case with the alternative second connecting element 5 expedient, since the installation on the front side of the shelf 2 not much wall thickness remains, so the pressure from the ribs is the shelf 2 deform in this area and could damage it.

A particular optical advantage arises in a reversed arrangement, when the alternative second connecting element 5 in the shelf wall 3 and the first connection element 4 in the shelf 2 is arranged. In the above-described horizontal arrangement of the alternative second connecting element 5 would then be in the installed state, the holding device above the shelf 2 not visible. In addition, this arrangement is inexpensive because the complex and therefore more expensive first fasteners 4 only in the shelves 2 are present and not in considerably higher numbers in the shelf walls 3 in the different available heights.

11 shows a sectional view of the alternative second connecting element 5 from 10 along the section line BB. As can be seen from the illustration, the depth of the recess is reduced 16 starting from the undercut 17 down, in particular, reduces the depth of the recess 16 gradually and without steps or edges to the value zero. This ensures that when dismantling the shelf 2 in which the shelf 2 with the second connecting element 5 opposite the shelf wall 3 with the first connecting element 4 is raised, the holding element 7 through the recess 16 is pressed in the direction of retracted retraction position, whereby the effect of the spring element 8th is additionally supported. However, it is also possible, the described holding element 1 with this alternative connection element 4 but without the spring element 8th and the corresponding area with enlarged cross-section 12 or the area of reduced cross-section, execute, wherein the provision of the retaining element 1 exclusively on the decreasing depth of the recess 16 he follows. This represents a separate invention in itself.

The embodiments described and shown in the figures can also be used in general for the connection of furniture pieces, for example for the positioning and fixing of stacked boxes. Due to the magnetic force, the holding device can be spatially freely arranged on the furniture. This is especially true in combination with the above-described additional magnetic elements for mutual positioning of the furniture parts to be joined.

In all embodiments shown, instead of the magnet 14 the holding element 7 of the first connecting element 4 be wholly or partially magnetic, in which case the second connecting element 5 consists of a magnetically attractable material such as steel, iron, etc. It is also possible to use both the second connection element 5 as well as the retaining element 7 of the first connecting element 4 wholly or partially magnetic perform. The poles of the magnets are to be aligned so that the holding element 7 to the second connecting element 5 is used when the second connecting element 5 comes near him. In order to achieve a visually appealing and uniform surface and designed as a magnet second connecting element 5 To protect against damage, the second connecting element 5 be covered by a cover, such as plastic, partially or completely.

The features disclosed in the individual embodiments can be readily combined according to the invention in order to achieve the desired effects and are not bound to the respective embodiment.
