Device for pivoting a pane, particularly on refrigerated or sales counters

The invention relates to a device of the type specified in the preamble of claim 1. Such devices are used in counters that serve to sell goods and can also be designed as refrigerated counters. The goods are presented to the customer in a visible manner inside the counter. A pane belonging to the device serves to protect the goods in the counter, which is preferably transparent in order to enable the customer to view the goods. The pane can be pivoted about a horizontal axis and is in a lowered position when the goods inside the counter are to be protected. However, the pane can be pivoted up into a raised position to fill the goods or to clean the inside of the counter.

For this purpose, the disc is attached to a joint part that is pivotally mounted in a bearing part. To make it easier to lift the disc, a force accumulator serves as a lifting aid, which is usually designed as a gas pressure spring. This force accumulator has two connecting ends, one of which is hinged to the movable joint part and the other is fixed in place. The two connecting ends are subjected to a force load in the sense of an increasing distance from each other. This force load makes it easier to lift the disc, holds the disc in its raised position and dampens the lowering of the disc. The pivoting of the disc between its lowering and lifting position takes place in an essentially vertical plane, which is why this will be referred to as the "pivoting plane" below. The direction of the force of the force accumulator is determined by the force acting on its two

the force exerted on the connection ends.

In the known devices of this type, the direction of force acting of the energy storage device was always arranged parallel to the pivoting plane of the disc. In the case of counters that have a horizontal plate, a so-called "payment plate" (EP-O 263 957-A2), horizontal support arms are required to attach them. The support arms have a U-profile and the two U-legs each form the bearing part for the pivoting joint part that holds the disc. The energy storage devices are arranged inside the U-profile and their connecting ends are supported by swivel joints on the one hand on the joint part and on the other hand on a fixed articulation point in the support arm. In the support arms, not only the energy storage device is arranged along its entire length, but also at least a section of the joint part. The support arms therefore have to have a certain minimum length, which leads to space problems in the counter. In addition, the position of the energy storage device is tied to the position of its support arm in the counter, which limits the freedom to set up a counter.

For counters that do not have a fixed payment plate but a curved disc (DE-90 04 215-U), the device must be modified. The energy storage devices are arranged inside hollow supports that protrude at an angle and are fixed to the counter body with their lower end. The bearing part for the joint part that carries the disc is located at the free, upper end of the support. Apart from the special design of the device for this counter, the disadvantage is that the arrangement of the energy storage device and the joint part is always tied to the support. Furthermore, installing the device inside the support is complicated. Finally, installing these parts requires the support to be large.

The invention is based on the task of developing a space-saving, versatile device of the type mentioned in the preamble of claim 1, which is easy to assemble and convenient to maintain. This is achieved according to the invention by the measures mentioned in the characterizing part of claim 1, which have the following special significance.

The invention is based on a new construction principle. The direction of the force acting on the energy storage device is no longer parallel to the pivoting plane of the disk, but intersects this pivoting plane. This makes it possible to have the longitudinal extension of the energy storage device run more or less transversely to the pivoting plane of the disk, in contrast to the prior art, and thus to minimize the dimensions of the device transversely to the pivot axis. In this way, when the disk is lowered, the direction of the force acting on the energy storage device can be made approximately parallel to the pivot axis. In the pivoting plane of the disk, i.e. perpendicular to its pivot axis, the device according to the invention only has a width that is determined by the size of the joint part, because the width of the energy storage device itself is normally much smaller than the joint part. In contrast, in the prior art, the length of the energy storage device is added to the size of the joint part in the pivoting plane. The overall length of the device according to the invention, which lies essentially in the direction of the pivot axis, is not a problem, however, because when the device is installed in a body, there is always sufficient space in the direction of the pivot axis. If the device is installed in a counter, for example, the previously mentioned payment plate runs in the direction of the pivot axis. Only a narrow zone is therefore required to install the device, which is why the width of the payment plate can be designed independently of this and can, for example, be very narrow. In addition, the space gained in the adjacent plate zone can be used to arrange further elements, e.g. light guide panels, in which light sources are mounted to illuminate the interior of the counter.

In the case of hinged windows in rail vehicles and buses (DE-19 88 255), it is known to arrange a longitudinally elastic spring strut between the free edge of the window and a bearing block. The bearing block protruded from a plane surrounding the window opening (opening plane) in the direction of the tilted open position of the window. The spring strut had the task of stabilizing both the open position and the closed position of the window in relation to the opening plane. From the fixed bearing block, the spring strut extended inclined towards the opening plane in the open position of the window and inclined away from the opening plane in the closed position of the window. In both positions, the longitudinal elasticity of the spring strut was relieved, which is why both when opening and closing the window, the spring strut was able to move freely.

additional force was required when closing the window. There is no indication of a lifting aid for swinging up a pane of glass.

Further measures and advantages of the invention emerge from the subclaims, the following description and the drawings. The invention is shown in several embodiments in the drawings. They show:

Fig. 10, 11 and 12, each in a cross section corresponding to Fig. 9 modified devices on three different sales counters, from which the universal application of the device according to the invention is evident.

The device is used to transfer a disc 10 between its lowering position shown in Fig. 1 and Fig. 9 in solid lines to its lifting position 10' shown in dash-dotted lines in Fig. 9. This includes the

from Fig. 2 and 3, which comprise a joint part 20. The joint part 20 has a receiving groove 21 tapering towards the groove opening, as shown in Fig. 9, which, in addition to the upper edge of the disk 11, also accommodates a retaining strip 12 with a wedge cross-section. With a given design, the angle of inclination 13 of the disk 10 in the lowered position can be achieved by simply changing the arrangement sequence of the disk edge U on the one hand and the retaining strip 12 on the other hand within the receiving groove 21 of the joint part 20. An additional variation of the angle of inclination 13 results if more than one retaining strip 12 is used and the order of arrangement of these retaining strips with the disk edge 11 is chosen differently.

■■:■ y

As can be seen from Fig. 2 and 9, the joint part 20 is assigned two bearing parts 30, which have holes 31 for two bearing bolts 32. The joint part 20 also has a through hole 22, which receives an end piece of each of the two bolts 32 and therefore, together with the bearing parts 30, determines the pivot axis 23 indicated in dash-dotted lines in Fig. 3. The joint part consists of a profile section with a rectangular outline, on the opposite rectangular sides 24 of which the two bearing parts 30 with the two aligned bearing bolts 32 come to rest. In addition, at least one energy accumulator 40 engages in a lateral offset 26 to the pivot axis 23, as shown in Fig. 4, namely at the points marked 25 on the rectangular sides 24 of the joint part 20.

The energy storage device 40 serves as a lifting aid for lifting the pane 10 in the sense of the pivot arrow 14 indicated in Fig. 9, which in this case is designed as a so-called "gas pressure spring". The pivot arrow 14 of the pane between its lowering position 10 and its lifting position 10' determines a pivot plane 15, which is the drawing plane in Fig. 9 and the position of which is indicated in dash-dotted lines in the perspective view of Fig. 1 and in Fig. 5. This pivot plane 15 runs vertically, i.e. is perpendicular to the horizontal pivot axis 23, as can be seen from both Fig. 1 and Fig. 5. The energy storage device 40 also serves to dampen the movement of the pane from its lifting position 10' to its lowering position 10 when the pane is pivoted back, in the sense of the pivot arrow 14' also shown in Fig. 9.

The energy storage device 40 has two connection ends 41, 42, which are subjected to force. As shown by the force arrow 43 in Fig. 2, one connection end 41 strives to move away from the other connection end 42. This extension movement 43 of the connection ends 41, 42 is limited by internal stops in the energy storage device 40. The force arrow 43 thus determines the direction of force 44 of the gas pressure spring 40, also indicated in dash-dotted lines in Fig. 2, and thus its longitudinal extension. The overall width 45 of the energy storage device 40 is small, as shown in Fig. 4, and takes up only a small amount of space parallel to the pivot plane 15.

As can best be seen from Fig. 5, the direction of force action 44 of the energy storage device 40 runs transversely to the pivot plane 15. In the lowering position of the disk shown in solid lines there, the energy storage device 40 extends essentially parallel to the pivot axis 23. As the dash-dot position 40' of the energy storage device in Fig. 4 and 5 shows, in the lifting position 10' of Fig. 9 the direction of force action, as shown 44', runs inclined to the pivot axis 23. The two positions 40 and 40' of the energy storage device can be seen from Fig. 4 and 5. When pivoting upwards and downwards 14, 14' of Fig. 9 the direction of force action 44, 44' describes a section of a conical shell, the cone tip of which is determined by a fixed position of the one mentioned connection end 42 of the energy storage device 40. There is a support part 50 which is fixedly positioned in the device of the invention . Because in the present case two mirror-image

arranged force storage devices on a common joint part 20 are used, two such support parts 50 are required, which are shown in Fig. 3 in their aforementioned inclination position 40'.

For mounting the above-mentioned components 20, 30, 40 and 50, a mounting base 60 is used, which is best seen in Fig. 2 and 3 and, apart from the molded-on guides 61, 62, is designed in this case as a substantially flat plate. The guides 61, 62 are formed as longitudinal rails in one piece with a profile bar, from which the mounting base shown is then cut to the desired length. The mounting base 60 therefore consists of a section of such a profile bar. According to Fig. 2, one guide 61 is used for mounting the two bearing parts 30, which for this purpose have a

the guide 61 have a complementary channel 33. This allows a sliding adjustment of the bearing parts in the longitudinal direction of the rail. During assembly, the two bearing parts 30 accommodate the joint part 20 between them and are fixed in a defined position by screws 34 indicated in Fig. 2 on the assembly base 60.

In a corresponding manner, the two support parts 50 also have channels 53 which, according to Fig. 2, are designed to complement the rail profile of the associated second guide 62 of the mounting base 60. The defined longitudinal position of the support parts 50 on their guide 62 is fixed by clamping screws 54 which penetrate corresponding threaded holes in the support part 50 until they engage the guide 62. The two energy storage devices 40 extend between the two support parts 50 on the one hand and the common joint part 20 on the other. For this purpose, the support part 50 has an engagement point 52, which is best seen in Fig. 4, for the stationary, outer connection end 42 of the respective energy storage device 50. So that the same type of support part 50 can be used optionally for both energy storage devices 40 which are mirror images of each other, the support part 50 has such engagement points 52 on both sides.

In the lowered position 10 of the disc according to Fig. 9, the joint part is in its swivel position 20 shown in solid lines in Fig. 4 to 6 below the mounting base 60. If a swivel movement is carried out in the lifting direction 14 of Fig. 9, the joint part reaches the swivel position 20' in front of the mounting base 60 shown in Fig. 9 and Fig. 4 and 5. As already mentioned, during this lifting 14, the two energy accumulators 40 also carry out a spatial movement until they assume the inclined position 40' shown in dash-dotted lines in Fig. 4 and 5. For this reason, the connecting ends 41, 42 and their points of engagement 25, 52 are designed as spatially effective rolling joints, in this case as ball joints. As can best be seen from Fig. 4, the two connection ends 41, 42 of the energy storage device 40 are designed as a ball head, while both the side surfaces 24 of the joint part 20 and the side surfaces of the two support parts 50 are designed as ball sockets 25, 52. In the pivoting position 20 of the joint part, where the direction of force 44 of the two energy storage devices 40 runs essentially parallel to the pivot axis 23, the force effects cancel each other out.

on the same side when the two energy storage devices have a substantially equal force load 43. The energy storage devices 40 are compressed to the maximum.

When the disc is lifted, a force component 46' is created that acts in the direction of the pivot plane, which increases with increasing inclination of the direction of force action 44, 44' and is illustrated in Fig. 4 by the force component 46' based on the pivoted position 20' of the joint part. This force component 46' counteracts the torque exerted by the disc weight on the joint part 20, 20' and increasingly supports the lifting of the disc in the lifting direction 14 of the arrow shown in Fig. 9 or reduces the disc weight in the lowering direction 14' of Fig. 9. As can be seen from the dash-dotted swivel position 20' of the joint part, the resulting force 43', as can be seen from the full inclination position 40' of the force accumulator, is also split into a component 47' running parallel to the swivel axis 23, which in the present case is compensated by the corresponding, oppositely directed force component of the other force accumulator arranged in a mirror image. The position of this other force accumulator is only indicated in Fig. 4 by its direction of force 44'. These two force components 47' parallel to the swivel axis do not load the two bearing parts 30, which is why these bearing parts 30 can be designed simply. If a force accumulator 40 is only allowed to act on one side, the opposite bearing part 30 should be designed as a thrust bearing in order to be able to absorb these parallel force components 47'.

The joint part 20 and its two bearing parts 30 and the two support parts 50 used to mount the force accumulators 40 together with the mounting base 60 form a pre-assembled, finished structural unit 70. The structural unit 70 can be attached to a support or the like from which the pivoting disc 10 is to extend. The joint part 20 located in this structural unit 70 is used as a holder for attaching the disc 10, but with one or two force accumulators 40 it already contains power sources that facilitate the raising 14 or lowering 14' of the disc 10. The structural unit 70 is therefore not only a holding means for the disc, but also a "power package" that has a beneficial effect on the pivoting movement 14, 14'. The pivoting position 20' of the joint

can be limited in part by rotation stops 35 on the bearing parts 30, as can be seen from the lifting position 10' of the disk indicated in dash-dotted lines in Fig. 9. As can be seen in Fig. 6, the support part 50 also has an arm 51, which with its free end engages behind a profile strip 63 located on the mounting base. In this embodiment, the profile strip 63 is part of the longitudinal guide 61 of the mounting base 60, which is used to mount the two bearing parts 30.

Fig. 7 shows a modified structural unit 70' compared to the previous embodiment, where the same reference numerals as in the previous embodiment have been used to designate the same components. It is sufficient to simply discuss the differences. In all other respects, the previous description applies.

The assembly 70' of Fig. 7 has a different type of mounting base 60'. This is not designed in the form of a plate, but has an angle profile with two legs 64, 65. One leg 64 is used to fasten the assembly 70' to a support and to mount the support parts 50. This is why the longitudinal rail 61 already mentioned is located there. This fastening leg 64 has the shape of a plate and the other leg 65 extends from it at an angle to it. According to Fig. 7, the mounted support parts 50 also have the previously described arms 51, which engage behind a profile strip 63. This also means that the torques exerted by the energy storage devices 40 on the support parts 50 are better absorbed. The profile strip 63 is here part of the bearing leg 65 of the angle profile. The other leg 65 has a continuous, longitudinal bore 66 at its free leg end, which is slotted lengthwise for manufacturing reasons, but has to fulfill the same functions that were fulfilled by the bores 31 of the previously described bearing parts 30 of the assembly 70. This mounting base 60' is also produced from a section of a profile bar with an angle profile. At the point at which the joint part shown in Fig. 7 in its swiveled-out position 20' is to be arranged, a recess 67 is cut out of this leg 65 and the joint part 20 is rotatably mounted via bearing bolts 32, which can best be seen in Fig. 8.

To produce the mounting base 60' of Fig. 8, a profile

Rod with the same angle profile as in Fig. 7, but cuts off a section with a correspondingly shorter length 68. In the application of Fig. 8, the energy accumulators provided on both sides of the joint part 20, which are shown in Fig. 7 in their inclination position 40', are dispensed with. The shorter mounting base 60' from Fig. 8 is used for an additional articulation point for particularly long panes. The longitudinal rail 61 for mounting support parts 50 is non-functional in the case of Fig. 8, in contrast to Fig. 7.

3 and 4, the overall width of the finished assembly 70 is determined by the mounting base 60, which has a small width 69. ^J This overall width 69 depends essentially on the side length 29 of the joint part 20, from which the bearing part 20 pivotally mounted on the bearing part 30 can only protrude by a small edge piece 28 in its pivoted-in position, as shown in Fig. 6. The decisive factor, however, is that the overall width 69 of this assembly 70 is no longer determined by the length of the energy accumulator 40, because according to Fig. 4, the energy accumulator in the parallel position 40 only extends with its minimum storage width 45 in this direction. In the pivot plane 15, the assembly 70 therefore has only a small overall width 69, which depends only on the side length 29 of the joint part. This has a very favorable effect on the space required by the assembly 70 when in use.

*— \ Fig. 9 shows a first application of this assembly 70 on a carrier

16 of a counter not shown in detail. This support 16 is made of wood material or similar and simultaneously functions as a "payment plate" of the counter. The structural unit 70 is attached to the underside 17 of this support 16 and there, due to the small construction width 69 described, only takes up a small plate zone 18. In the adjacent plate zone 39 the underside of the support 17 can already be used to attach further components, e.g. light sources 27, which in this case consist of fluorescent tubes. An angled beam 38 is arranged between them, to which a front support 37 of the counter, indicated by a dot-dash line, can also attach. The beam 38 also serves as a light shield. A front strip 49 can be used to cover the attached structural unit 70. The top 19 of the support 16 is free for its function as a "payment plate".

Fig. 10 shows, in a representation corresponding to Fig. 9, a modified sales counter in which the support is made of an extruded profile 56. There, a substantially identically designed structural unit 70 can be mounted in a corresponding manner in a front zone on the support underside 91. The rear zone 57 of this extruded profile 56 serves to fasten this profile 56 to a support 48 that protrudes obliquely from the counter body. In the middle zone in between

55, a light guide panel 58 is integrated into the extruded profile 56, in which the fluorescent tubes mentioned above can be attached as a light source 27. The joint part 20 used here has a cross-sectional profile that is modified compared to Fig. 6, which in the lowered position ensures a flatter course of the pane 10 compared to Fig. 9 and therefore leads to a steeper lifting position 10' of the pane, which is indicated in dash-dotted lines in Fig. 10. In the present case, too, the mentioned minimal construction width of the structural unit 70 has a favorable effect, because the extruded profile

56 only needs to have a small profile width 59.

In Fig. 11, an extruded profile also serves as the support 36, which, however, in addition to a light guide cover 58', also has a molded profile piece 72. This support 36 serves to support an additional payment plate 73 of the counter there, for which a rear-facing profile tab 74 is provided on the profile piece 72. A front strip 79 is also provided on the profile piece 72, facing opposite the profile tab 74. This front strip 75 runs approximately at the same height as the top of the payment plate 73 and shields the lower area of the profile piece 72, the underside 81 of which again serves for mounting a structural unit 71 according to the invention. As can be seen from the hatching, this structural unit 71 has a mounting base 60' with integrated holes 66 for a joint part 75 of this structural unit 71, which determine the pivot axis, similar to the second embodiment of Fig. 7. The mounting base 60' of this structural unit 71 here takes up an inclined position in the support 36. The rear area of the payment plate 73 is supported on a flat rail 76, which, similar to the profile tab 74 of the profile piece 72 of the support 36, is supported by a short horizontal arm 77 of a support 78. The support 78 extends obliquely from a counter body, not shown in detail. The fastening location of the structural unit 71 on this support 36 is, however, completely

independent of the position of the horizontal arms 77 and the supports 78.

In the embodiment of Fig. 11, the pane 10 is not attached directly to a joint part 75, but indirectly via a continuous holding rail 80. This holding rail 80 encompasses the pane edge 11 along its entire length. The holding rail 80 has the corresponding receiving groove 21' in which this pane edge 11 is clamped together with a holding strip 12. To connect the holding rail 80, the joint part 75 has an undercut groove in which a rail head of the holding rail 80 engages and is secured by clamping screws or the like. The holding rail 80 initially has the task of covering the entire structural unit 71 for a front-side viewer in the lowered position 10 of the pane. The joint part 75 has a three-armed cross-section, on one arm of which the holding rail 80 sits, while another arm creates the pivot bearing with the bore 66 of the mounting base 60'. This second arm creates a recess 81 with the holding rail 80, the significance of which can be seen from the pivoting position 75' of the joint part shown in dash-dotted lines. In this position, the recess reaches position 81' and can encompass the previously mentioned front strip 79 belonging to the carrier 36.

In the last embodiment of Fig. 12, a curved front panel 10 is used for a counter that does not need to have a payment plate or the like. Here too , a structural unit of almost the same design can be used.

71. This structural unit 71 is equipped with the matching mounting base 60 already described several times. In this case too, supports 78 extend diagonally upwards from the counter body, to the free end of which a particularly narrow extruded profile acting as a support 86 is attached. In the support 86, similar to Fig. 10, a light guide panel 83 for attaching light sources 27 is integrated. The horizontal arms 77 mentioned in the previous embodiment can be omitted here. The supports 78 engage the underside 84 of the support 86, where the light guide panel 83 also opens.

The special feature of the embodiment of Fig. 12 is that the upper side 85 of the support 86 serves to attach the structural unit 71. In comparison with the embodiment of Fig. 2 and 3, therefore,

9·*

the support parts 50 on the front side, while the bearing parts 30 of the assembly 71' point to the rear. It is sufficient to use a joint part 90 with a correspondingly adapted cross-sectional profile, because in all other respects all other components of the assembly 70 shown in Fig. 3 can also be used for this assembly 71'. The joint part 90 has a Z-shaped cross-sectional profile here. In this case too, the disc 10 is indirectly connected to the joint part 90 via a holding rail 88. This holding rail 88 is also connected to the joint part 90 via a complementary engagement profile and surrounds the disc edge 11 over its entire length. The holding rail 88 has two profile legs 87, 89, which in the lowering position 10 of the pane shown in solid lines in Fig. 12 cover the strip on the upper side 85 of the support used to arrange the structural unit 71. The structural unit 71' is, however, easily accessible if the pane is moved to its lifting position 10' shown in dot-dash lines in Fig. 12.

In a modification of the designs shown in Fig. 10 and 11, the described guide 61 or guides 61, 62 for the respective bearing parts 30 or support parts 50 could be molded directly onto the underside 61 or 82 of the extruded profile 56 of Fig. 10 or the profile piece 72 of Fig. 11 instead of onto the mounting base 60 or 60'. Accordingly, these guides could be located on the upper side 85 of the support in the design of Fig. 12. Instead of pre-assembling the components to form the described structural units 70, 71, 71', the components in this modified design are mounted directly onto the supports 56, 36, 86.

The device according to the invention or the components produced with it could be mounted on other housings in addition to counters, e.g. on cover housings for electrical controls. Tailgates of vehicles could also be equipped with the device according to the invention.
