Description

Furniture fitting for a combined sliding and pivoting movement of a multipart door and piece of furniture having such a furniture fitting

Technical Field

The invention relates to a furniture fitting for performing a combined sliding and pivoting movement of a multi-part door having at least a first and a second panel element. The furniture fitting has a sliding guide for a first panel element and a pivot guide for the first and second panel elements, wherein in a first movement phase the first panel element is guided linearly displaceably relative to the second panel element by the sliding guide and in a second movement phase the first and second panel elements are coupled together and are guided pivotably together by the pivot guide. The invention also relates to a piece of furniture having a multipart door and such a furniture fitting.

Background

In particular, in top cabinets, doors that perform a purely pivoting movement are disadvantageous since they are usually used in kitchens, since the open door projects far into the room and there is a significant risk of injury in the head region. Alternatively, the top cabinet may be equipped with a sliding door, in which case the open door does not protrude into the room, but access to the interior of the furniture is limited, since only a portion of the interior of the cabinet (e.g., in a two-part sliding door, only about half of the interior of the cabinet) is always accessible at the same time.

With the furniture fitting for a combined sliding and pivoting movement described above, a compromise is created, by means of which good accessibility of the furniture interior can be achieved, since the opening door projects into the space as little as possible.

From document DE 1812507 a door arrangement is known in which a door wing is formed, which is arranged on the cabinet top to be pivoted outwards and is formed in two parts. In the first pivotable panel element of the door leaf, the second panel element can be extended or retracted. When the door is arranged closed, the second panel element extends downwardly from the first panel element such that the entire furniture opening is closed. To open the door, the second panel element may be retracted, thereby providing access to the lower half of the cabinet. The two mutually retracted panel elements are then pivoted together about their upper edges to make the upper part of the cabinet accessible.

A disadvantage here is that the two mutually retracted panel elements pivot about a rotational axis located at the edge of the pivotable panel element. Thus, in the open state, the entire arrangement of mutually retracted panel elements is always fully extended forward on the front edge of the cabinet. In addition, a large force is required to keep the open door arrangement in a horizontal position. For this purpose, lateral support bars are used to support the open door at its side edges. The supporting rod also extends forwards on the cabinet body.

From document US 2,322,377 a multi-part door is also known which performs a combined sliding and pivoting movement. This arrangement is particularly suitable for large doors, such as building doors. Also in this arrangement the upper panel element is pivotably mounted and at least one second panel element is displaceably arranged on said first panel element.

To open the door, the lower panel element is raised on the upper panel element, and the arrangement of the two panel elements is then pivoted into an approximately horizontal position. Contrary to the first mentioned document, in which the rotation axis is arranged at the upper end of the first panel element for the pivoting movement, in this case the upper end of the first panel element moves on a guide curve substantially horizontal to the interior. In a lower region of the first panel element there is articulated a pivoting lever which, in combination with a sliding movement at an upper end of the panel element, results in a combined pivoting and sliding movement of the door arrangement. In the open position, the door arrangement is substantially horizontally aligned and retracted at least partway into the interior.

Turning to furniture such as a cabinet, in the open position the door assembly will project slightly forward into the room on the furniture body. However, it is disadvantageous that the door arrangement is moved into the cabinet interior, so that a part of the interior space is no longer available as a storage space. Furthermore, due to the inwardly telescopic door, the end faces of the side walls of the furniture body cannot be covered by the door, so that a uniform furniture front cannot be achieved by arranging the furniture items in a side-by-side manner.

Disclosure of Invention

It is an object of the invention to provide a furniture fitting or furniture of the above-mentioned type in which the multipart door in the open position projects only slightly forward of the furniture body and does not project into the storage space of the furniture.

This object may be achieved by a furniture fitting or furniture according to an embodiment of the present disclosure. A furniture fitting of the above-mentioned type according to the invention is characterized in that the pivot axis of the pivot guide is positioned at a distance from the plane in which the door extends, so that the panel elements coupled in the second movement section are guided in a rotational and translational movement. According to the invention, the pivoting movement is thus not performed about a pivot axis which lies in the plane of the panel element, but about an axis which lies outside the surface plane of the door, in particular the pivot axis is located further towards the rear side of the body. The door is then pivoted so that it performs a combined rotational and translational movement and is pushed at least partially over the body so that it does not protrude further into the room. The pivot axis may be located, for example, at least temporarily, i.e. in a partial phase of the movement, above the top plate of the furniture carcass.

In an advantageous embodiment of the furniture fitting, the pivot guide has a lever mechanism with two levers. Preferably, the levers are each hinged to a base plate which can be mounted in the furniture body and to a support profile which is pivotably mounted in this way. A lever mechanism with two levers makes it possible to realize a pivot guide whose pivot axis lies outside the door plane in a structurally simple and space-saving manner, for example by means of levers which are not aligned parallel to one another. The lever is arranged in a plane running parallel to the side of the furniture body. In this plane, they are not aligned parallel, i.e. extend obliquely to one another, which leads to such a pivoting movement: the pivot axis of which is located outside the door and also at least partially outside the lever mechanism.

In this case, one of the levers may be coupled to an actuating lever connected to the linear guide. In this way, the pivoting movement can be motorized, since the output member of the linear guide acts on the lever mechanism via the actuating lever.

In an advantageous embodiment of the furniture fitting, the sliding guide has at least one guide profile and a roller carriage which runs therein with rollers. Preferably, the guide profile has: a first section for attachment to a furniture body; and a second section, by means of which the pivot guide is guided pivotably, wherein in the first movement phase the roller carriage is guided from the first section into the second section. The sliding guide is thus provided such that it is stably and firmly carried by the body in the first section, and the roller carriage and thus the door can be pivotably supported by the pivot guide in the interaction guide in the second section.

Alternatively, the slide guide may include at least one pull-out guide that guides the first panel element in a linearly displaceable manner with respect to the second panel element. Preferably, the pull-out guide is then pivotably guided together with the second panel element by the pivot guide. In this case, it is advantageous that only a slightly modified standard component may be used as the sliding guide, due to the pull-out guide.

For connecting the panel element to the pull-out guide, a support frame is preferably provided parallel to the second panel element, which support frame is guided pivotably together with the second panel element by means of a pivot guide, and on which the pull-out guide is mounted. In order to support the guiding of the first panel element, the sliding guide can also have at least one guide profile for attachment to the furniture body and guide rollers running therein. A particularly simple construction is achieved when the guide roller is attached to the pull-out guide.

In order not to interfere with the pivoting movement, the guide profile is designed and arranged such that the guide roller leaves the guide profile at the end of the first movement section and does not engage with the guide profile in the second movement section. This achieves that the guide roller supports the sliding movement only in the first movement phase. In this movement phase, the pull-out guide is moved out furthest, so that the guide support effected by the guide rollers in this movement phase is particularly useful.

A piece of furniture according to the invention, in particular a top cabinet, has a main body and a multi-part door comprising at least a first panel element and a second panel element in planes spaced parallel to each other. The piece of furniture is characterized in that the panel element is fastened to the body by means of at least one furniture fitting described above and is guided by means of the furniture fitting. This results in the enumerated advantages associated with furniture fittings.

In an advantageous embodiment of the piece of furniture, the sliding guide for the first panel element is arranged at least partially in a side wall of the main body. More preferably, the pivot guide of the second panel element is mounted on an intermediate plate of the main body, wherein the intermediate plate is arranged in an upper region of the main body. In this way, the furniture fitting is integrated on the furniture without protruding into the interior. This is important for both practical reasons as well as for visualization reasons. The electric drive can be integrated very well by means of at least one bowden cable and/or at least one rotary shaft acting on the furniture fitting.

Detailed Description

Fig. 1a to 6 described below show a first embodiment of a piece of furniture with a furniture fitting according to the application. As an example, especially the top cabinet of a kitchen is shown as furniture. It will be appreciated that the furniture fitting according to the present application may also be used for other furniture items or for other purposes of doors.

In the furniture shown, the sliding movement of the door takes place in the vertical direction and the pivoting movement takes place about a horizontal axis. However, the furniture fitting shown can in principle also be used in doors which are displaced in the horizontal direction and which pivot about a vertical axis.

Fig. 1a-1f show an exemplary piece of furniture with doors in various open positions in an overall isometric view.

The furniture has a body 10, which body 10 has two side walls 11, a bottom 12, a top plate 13 and a rear wall 17. As shown in fig. 1f, an intermediate plate 14 is provided below the top plate 13, the intermediate plate 14 closing at the top the interior 16 of the body 10. Further, the interior 16 may optionally be subdivided by shelves 15.

The intermediate space between the top plate 13 and the intermediate plate 14 accommodates the components of the furniture fitting and an optionally provided electric drive 50, which electric drive 50 is coupled to the furniture fitting. In order to make accessible the components of the electric drive 50, a penetration is provided in the top plate 13, the top plate 13 being covered by a cover 131 for installation and maintenance purposes. A smaller opening is again provided in the cover 131, through which the inscription can be checked. The power and control cables of the electric drive 50 pass through one or more openings in the rear wall of the body 10.

The furniture has a multi-piece door 20, which multi-piece door 20 comprises a first panel element 21 and a second panel element 22. The panel elements 21, 22 (hereinafter also referred to as front panels 21, 22) are glass plates in the example shown. In principle, other materials, such as wood, can also be used for the

front panels

21, 22 of the door 20.

Fig. 1a shows the piece of furniture in the state in which the door 20 is closed. One of the

front panels

21, 22 is arranged below the other, wherein an upper second front panel 22 is arranged parallel spaced in front of a lower first front panel 21, and the first front panel 21 overlaps slightly, for example by a few centimeters, at its upper side edge.

To open the door 20, the first (i.e. lower rear) front panel 21, which is first behind the second (i.e. upper front) front panel 22, is first moved vertically upwards in a first path stage until the state shown in fig. 1c is reached. At this stage, a lower, generally lower half of interior 16 is accessible.

To open the door 20 further, the arrangement is pivoted back and up from the now overlapping first and second

front panels

21, 22 together with their upper edges, so that now the upper part, i.e. substantially the upper half, of the interior 16 of the main body 10 is also accessible to the user.

The pivoting occurs about a horizontal pivot axis that is positioned approximately at the height between the mid-plate 14 and the top plate 13 behind the door 20. Due to the arrangement of the pivot axis, the door 20 protrudes only slightly forward beyond the side wall 11 of the main body 10 after pivoting. The rest of the door 20 pushed together is located above the main body 10.

Generally, even in the case of having a top cabinet between the top plate 13 of the main body 10 and the ceiling of the room, there is enough space to accommodate the portion of the door 20 in the opened state. In the open state, no portion of the door 20 is disposed in the interior 16 of the body 10. Thus, the interior 16 is substantially fully available to the user.

In fig. 2a-2f, the opening sequence corresponding to fig. 1a-1f is shown in a side view of the door 20 of the piece of furniture. In these figures the side wall 11 of the body 10 facing the viewer is removed for a thorough understanding of the construction and operation of the furniture fitting. Fig. 3 shows an enlarged view of the upper part of fig. 2 e. In fig. 3, the details of the construction of the furniture fitting according to the invention can be identified, which will be discussed below.

Fig. 2a first shows the closed state of the door 20. With the position of the front panel 22 unchanged, the rear front panel 21 is moved vertically upward to open the door 20, as shown in fig. 2b and 2 c. In the state of fig. 2c, the lower edges of the two

front panels

21, 22 are at the same height. In the embodiment shown, the two front panels also have substantially the same dimensions, so that in the state shown in fig. 2c the upper edges of the

front panels

21, 22 are also substantially at the same height. In other words, the two

front panels

21, 22 are arranged behind one another in close conformity.

For the linear displacement of the first front panel 21, a sliding guide 30 with a guide profile 31 is used, wherein a roller carriage 32 is guided vertically movably by means of rollers 321. The roller frame 32 is provided with a fastening mechanism for the first front panel 21. The fastening mechanism may comprise a mounting bracket to which the first front panel 21 is attached. The mounting bracket provides a fastening mechanism adapted to correspond to the material of the first front panel 21. On the roller carriage 32, four rollers 321 are provided in the case shown, by means of which the maximum possible play-free movement of the roller carriage 32 in the guide profile 31 is possible.

First, the upper roller 321 that faces forward in the mounted state and the lower roller 321 that faces rearward in the mounted state are loaded in terms of force. Two intermediate rollers 321 arranged between the rollers are provided for a play-free arrangement of the roller frame 32 within the guide profile 31. They may, for example, be mounted on an eccentric arrangement, not shown here, which allows the position of the rollers 321 to be adjusted laterally. Alternatively, at least one groove may be formed in the roller frame 32 to enable adjustment of each roller 321 as needed to minimize play.

The illustrated slide guide portions 30 are preferably provided on both sides of the main body 10 to guide the first front panel 21 uniformly on both sides. In order to impair the usability and accessibility of the interior 16 of the body 10 as little as possible, the guide profiles 31 of the sliding guide 30 are preferably embedded in recesses, such as cutouts on the inside of the respective side walls 11.

The linear movement of the first front panel 21 shown in fig. 2a-2c may be substantially done manually. In the embodiment shown, an electric drive is provided which acts on one or more cables (not visible in these figures) on the first front panel 21 and/or the roller frame 32.

After reaching the position shown in fig. 2c, further opening of the door 20 is achieved by co-pivoting of the first front panel 21 and the second front panel 22, as shown in fig. 2d-2 f. In the example shown, this movement is also electrically driven, but can in principle also be performed by manual operation. In the case of an electric drive, the motion control means is arranged such that pivoting takes place only when the position shown in fig. 2c is reached. In the mechanical actuation of one or other movements, a locking device may be provided, by means of which the pivoting movement is released only when the first front panel 21 is moved completely behind the second front panel 22.

The illustrated pivotal movement may be achieved by a pivot guide 40. The pivot guide 40 comprises a base plate 41 fixed with the body and a support profile 43, which support profile 43 is pivotably connected to the base plate 41 via a lever mechanism 42. In the example illustrated, the lever mechanism 42 comprises two

levers

421, 422, which are mounted on both the base plate 41 and the support profile 43 with

hinges

4211, 4212, 4221, 4222, respectively (see fig. 2 a). The

levers

421, 422 have different lengths between their pivot points and are arranged not parallel to one another, so that the support profile 43 performs a pivoting movement in the region of the side wall 11 about a horizontal pivot axis spaced from the door 20. In this case, the

hinges

4211 and 4212 and 4221 and 4222 each form a pair of hinges whose connecting lines extend to intersect at a point on the pivot line or instantaneous bar M for the doors 20 being pushed together. The momentary lever M is not fixed during the pivotal movement of the door 20, but stably varies by traveling on the momentary lever rail. In order to enable the doors 20 pushed together to move away from the main body 20, the momentary lever M is located above the top plate 13 at the beginning of the pivoting movement and shortly thereafter. Thus, the doors 20 being pushed together achieve a combined rotational and translational movement. The above steps ensure that in the fully opened state of the door 20, the pushed-together door 20 is at least partially located above the body 10 and thus protrudes less into the room accordingly.

On the support profile 43, the second front panel 22 is fixed by a U-shaped support bracket 44 projecting forward. The support bracket 44 spans the area between the second front panel 22 and the support profile 43, wherein the roller bracket 32 and the first front panel 21 can be retracted.

The rod 421 forms an angle with the other lever arm to which the actuation lever 45 is linked. The actuating lever 45 is coupled to the driven member 461 on the linear guide 46. The sliding movement of the horizontal driven member 461 in the example shown is achieved via a pivoting movement of the actuating lever 45 and the

rods

421, 422 into the support bracket 44 and the door 20.

As can be seen in fig. 2d-2f and 3, the guide profile 31 of the sliding guide 30 is formed in two parts. It comprises a first lower section 311, which first lower section 311 is fixedly connected to the furniture carcass 10 by means of the side wall 11. The guide profile 31 further comprises a second upper section 312, which second upper section 312 is arranged on the support profile 43 and pivots with the support profile 43. The length of the upper section 312 is sized so that the roller frame 32 can fully enter the section. In the downward pivoted state of the pivot guide 40 (see fig. 2a-2c), the two

sections

311, 312 of the guide profile 31 are in line, so that the roller frame 32 can move seamlessly from the lower section 311 into the upper section 312 when moving the first front panel 21 upwards, and the roller frame 32 can move seamlessly from the upper section 312 into the lower section 311 when moving the first front panel 21 downwards.

Fig. 4 shows a front corner region of an article of furniture in horizontal section. In this figure it can be seen how the guide profile 31 is embedded in the side wall 11 of the body 10. Next, one can see the arrangement of the rollers 321 and the side rollers 33, the rollers 321 being arranged in corresponding c-shaped guide chambers 313 in the guide profile 31, the side rollers 33 extending along the front advancing surface 314 of the guide profile 31 to guide the door 20 laterally (i.e. in a direction perpendicular to its direction of travel).

Fig. 4 shows a further guide element for guiding the front panel 21 relative to the front panel 22 in addition to the sliding guide 30. In each case, a side profile 47 is fixed (for example glued) at the side edge of the second front panel 22, the side profile 47 being mounted on the support bracket 44. The side profiles 47 serve on the one hand as side covers or for visual protection and on the other hand for guiding the first front panel 21 relative to the second front panel 22. The side profile 47 has a channel 471 for guiding purposes, in which channel 471 the guide finger 211 slides, which is indirectly arranged on the first front panel 21.

Other guiding elements are provided by the roller bracket 23 together with the interposed roller 231, the interposed roller 231 being rotatable about a horizontal axis. The roller brackets 23 are mounted, preferably glued, on the second front panel 22 and run with their rollers 231 over the surface of the first front panel 21. Two or more of these roller carriages 23 may be arranged side by side and/or in a distributed manner one above the other on the inner side of the second front panel 22.

Fig. 5a, 5b and 6 show two different embodiments of an electric drive 50 for the electric movement of the door 20. Fig. 5a and 6 show the piece of furniture from behind and above, respectively, in an isometric oblique view, with the rear wall 17 and the top plate 13 removed. Fig. 5b additionally shows the embodiment according to fig. 5a in a plan view of the intermediate bottom plate 14, the top plate 13 likewise being removed.

In the embodiment shown in fig. 5a and 5b, the electric drive 50 comprises a pivot drive 51 and a lift drive 52, both pivot drive 51 and lift drive 52 being mounted on the intermediate plate 14. The pivot drive 51 has an electric motor (not visible here), the gearing of which acts on a rotary shaft 511 passing through the drive. The rotational axis 511 extends over the entire width of the furniture body 10 and in each case terminates on the right and left side of the linear guide 46. Upon actuation of the pivot driver 51, the rotational movement of the rotary shaft 511 is converted into a synchronous linear sliding movement of the respective driven members 461 in the two linear guides 46. Actuation of the pivot driver 51 correspondingly causes the door 20 to pivot through the pivot guide 40.

The lift drive 52 also has an electric motor with a downstream transmission (e.g., a worm gear) that acts on the bowden cable 521. The bowden cable 521 compensates for the pivoting movement of the pivot guide 40 and enters two cable pulling devices (not visible here) which are attached to the roller frame 32. Actuation of the lift drive 52 causes both roller frames 32 to be raised or lowered simultaneously, thereby raising or lowering the first front panel 21 relative to the second front panel 22.

As described above, the sequence control means is provided such that the pivot driver can only be operated when the lift driver 52 has fully raised or at least almost fully raised the first front panel 21 to a desired height.

In an alternative embodiment of the electric drive 50 according to fig. 6, a pivot drive 51 and a linear actuator 52 are also provided. The pivot drive 51 is formed identically as in the example of fig. 5a and 5 b. However, the lifter drive 52 is not disposed on the intermediate plate 14, but is mounted on the support bracket 44 such that the lifter drive 52 is moved together when the door 20 is pivoted. In this way, the bowden cable 521 can be omitted or the bowden cable 521 can be formed shorter, in particular, the driving movement of the sliding guide 30 does not have to be transmitted by a pivoting movement.

It should be noted that the type of power transfer shown between the driver and the moving element is purely exemplary. For example, instead of a cable pulling device, a spindle drive can also be used to implement the lifting movement.

In fig. 7a-13, another embodiment of a piece of furniture with a furniture fitting for a combined sliding and pivoting movement of a door according to the application is shown. In the present exemplary embodiment, the same reference numerals denote the same or equivalent elements as in the first embodiment. The second exemplary embodiment is illustrated with reference to a main body 10 and an equivalent door 20 of a substantially identical top cabinet, for example for a kitchen. Reference is explicitly made herein to the embodiment of the first exemplary embodiment.

Fig. 7a to 7c show, by way of example, three phases of the opening operation of the two-piece door 20 in a manner comparable to fig. 1a to 1 f. The door 20 in turn comprises a lower first panel element 21 (also referred to as first front panel 21) and an upper second panel element 22 (also referred to as second front panel 22).

In the second embodiment, the pivot guide portion 40 corresponds to the pivot guide portion of the first embodiment. In this regard, a more detailed explanation will not be provided. The slide guide 30 implemented by the pull-out guide in combination with the roller guide in the second embodiment is different.

Figures 8a-8c each show a side view of the piece of furniture with the side wall 11 removed, in a similar manner to figures 2a-2 f. The positions shown correspond to the positions of fig. 7a-7 c.

In order to enable the first front panel 21 to move relative to the second front panel 22, the two front portions are coupled together via a pull-out guide 34. When the first front panel 21 is fully raised (compare fig. 7b and 7c), the pull-out guide 34 is fully retracted and pivots together with the

front panels

21, 22.

When the first front panel 21 is lowered (see fig. 8a and 9a), the pull-out guide 34 is extended. In this state, the respective tracks of the pull-out guide 34 can be seen: an outer track 341, a middle track 342 and an inner track 343. The outer rail 341 carries the movable first front panel 21, and the inner rail 343 is a support bracket 44 attached to the pivot guide 40 together with the second front panel 22. The details are explained in the drawings described below. The intermediate rail 342 allows the first front panel 21 to fully extend relative to the second front panel 22. Thus, the pull-out guide 34 represents a fully extended portion.

As another guide mechanism, a guide roller 35 is provided at a lower end region of the outer rail 341. When the door 20 has completed the pivoting operation and just before the first front panel 21 is moved linearly downwards (fig. 8b, fig. 10), the guide roller 35 is pivoted into the recess 111 in the side wall 11. When lowering the first front panel 21, the guide rollers 35 reach the guide profile 31, which guide profile 31 is embedded in the side wall 11, corresponding to the lower section 311 of the guide profile 31 of the first embodiment.

In principle, the guidance of the first front panel 21 relative to the second front panel 22 can also be achieved solely by the pull-out guide 34 without additional roller guidance of the guide rollers 35 in the guide profile 31. However, the additional roller guide results in a more accurate guide of the first front panel 21.

In fig. 9a-9c, the door 20 is shown in isometric view in the left half of the picture, separated from the furniture, and in side view in the right half of the picture, in the pull-out guide 34 in different extended positions.

In fig. 9a, the pull-out guide 34 extends as far as it corresponds to the closed door 21, for example according to fig. 7a or 8 a. Fig. 9c shows the fully retracted position of the door 20, in which the first front panel 21 has been moved fully to the second front panel 22 (see fig. 7b or fig. 8 b). Finally, fig. 9b shows an intermediate position in which the first front panel 21 has been moved partially behind the second front panel 22. Fig. 9a-9c show that the pull-out guide 34 with the corresponding inner rail 343 is not mounted directly on the second front panel but on an additional support frame 24, which additional support frame 24 is arranged parallel to the first front panel 21 or the second front panel 22 and is connected at the upper end to the second front panel 22 spaced from the second front panel 22. The pull-out guide 34 is mounted on a lateral end face of the support frame 24. The first front panel 21 moves relative to the second front panel 22 between the second front panel 22 and the support frame 24 upon activation.

Fig. 10 shows a detailed view of the upper end region of the guide profile 31, the guide profile 31 entering into the recess 111. The illustrated state represents the arrangement of the first front panel 21, the second front panel 22, and the support frame 24 at the time of just starting or just ending the inward or outward pivoting operation. At the upper edge region, the guide profile 31 widens in a funnel-shaped manner and has a chamfer 315, which chamfer 315 facilitates the insertion of the guide roller 35.

Fig. 11 shows a horizontal cross-section of the furniture body 10 and the front corner region of the door 20. In this figure, the arrangement of the guide tracks 34 and the guide rollers 35 and the positioning of the guide rollers 35 in the guide profile 31 can be clearly seen. Furthermore, it is possible to see the side profile 47 with the channel 471 mounted on the second front panel 22, wherein the guide finger 211 is slidably guided in the channel 471, the guide finger 211 being fixed to the first front panel 21.

Fig. 12 and 13 show two different electric drives 50 for the sliding guide 30 and the pivoting guide 40. The embodiment of fig. 12 is similar to the driver alternative shown in fig. 5a and 5 b.

The electric actuator 50 includes a pivot actuator 51, and the pivot actuator 51 acts on the linear guide 46 via a rotary shaft 511. Details of the pivot guide 40 and the pivot driver 51 are given in connection with the first embodiment, to which reference is made. Further, the lifter actuator 52 is also attached to the intermediate plate 14, and the intermediate plate 14 acts on the slide guide 30 via the bowden cable 521. As explained in connection with the examples of fig. 5a and 5b, the bowden cable 521 for example converges to a cable (not shown here) which is directly or indirectly attached to the first front panel 21.

A similar driving concept to the example shown in fig. 6 is shown in fig. 13. In this case, the electric drive 50 further comprises: a pivot driver 51 mounted on the intermediate plate 14; and a separate actuator for the sliding guide 30 from the pivot actuator 51, wherein the separate actuator is also pivoted.

The drive for the sliding guide 30 is here designed in the manner of a roller shutter drive 53, which comprises an elongated tube with an internal motor, which tube extends approximately over the entire width of the body 10. During operation of the motor, the entire tube rotates. In the end region, the cable pulling part 531 is wound, which is directly or indirectly connected to the first front panel 21, so that the first front panel 21 is uniformly (simultaneously) raised on both sides.

As shown, the cable pulling part 531 may be hung on the lug 212, and the lug 212 is connected to the first panel element 21 or to the inner rail 343 of the pull-out guide 34. It is conceivable to attach only the cable pulling part 531 to the inner guide rail 343. For example, the cable pulling part 531 may be attached to a bearing pin of the guide roller 35.
