Description

State of the art

Systems or connecting devices for connecting a sliding element of a piece of furniture or a household appliance to a guide rail of a guide system of the furniture or household appliance are known in various variations.

For example, so-called partial extensions with two guide rails or full extensions with three guide rails, based on one extension unit, are used as guide systems, the rails being telescopically movable with respect to one another.

As a rule, a sliding element such as a drawer, a storage shelf, a food rack or the like is accommodated in a displaceable manner via exactly two separate, similar structural units of a partial extension or a full extension. The respective structural unit of the pull-out guides is preferably attached to an inside of a furniture body or a housing of a household or kitchen appliance.

Since the connection of a sliding element of a piece of furniture or a household appliance to a guide rail has to meet high requirements with regard to functionality, user-friendliness and economy, further developments in this regard are necessary.

the CN 107 224 124 A relates to a device for height and side adjustment of a drawer relative to a rail guide.

Object and advantages of the invention

The object of the present invention is to provide furniture or connecting devices described in the introduction for connecting a push element of a piece of furniture or a household appliance, such as, for. B. to improve a kitchen appliance with a guide rail of a guide system of the furniture or household appliance, in particular with regard to function, operability and economic production.

This problem is solved by the independent claims.

The dependent claims deal with expedient and advantageous developments of the invention.

The invention is based on a device for connecting a movable push element of a piece of furniture to a guide rail of a guide system of the furniture or for connecting a movable push element of a household appliance, such as a kitchen appliance, to a guide rail of a guide system of the household appliance or kitchen appliance. It is preferably a question of a correctly positioned and secured and / or releasable connection of the push element and guide rail to the device. The device can preferably be fixedly but detachably attached to the thrust element, for example screwed on with screwing means. The device is preferably formed as a unit which is separate from the pushing element and the guide rail and is effective between the pushing element and the guide rail. In particular, the device is first attached to the pusher element and then, together with the pusher element, when it is attached to the guide rail of the guide system, which is in particular already mounted on the furniture or household appliance, is brought into detachable attachment contact with the guide rail or latched onto it. In addition, the device is coordinated in such a way that a connection between the push element and the guide rail can only be established when the push element and the guide rail are correctly positioned to each other. For this purpose, sections that are matched to one another are prepared prepared on the connecting device on the one hand and the guide rail or an intermediate piece attached to the guide rail on the other hand.

The essence of the invention lies in the fact that the device has adjustment means, the adjustment means comprising latching means, an operating element and a height adjustment element, the latching means having latching teeth and a latching member, the latching teeth being arranged along a lateral surface, the latching member being connected to the operating element is, wherein the locking member engages with the locking teeth, wherein the height adjustment element is disc-like, wherein the height adjustment element is pivotable, in particular rotatable on the device, the operating element is connected to the height adjustment element, and the device in the arranged state with the thrust element what connects the guide rail is that a change in position of the height adjustment element causes a change in position of the push element relative to the guide system, in particular a change in the distance of the push element relative to the guide rail. The change in distance of the push element relative to the guide rail, which can be made at any time after the connection of the push element to the guide rail, relates in particular to a vertical distance in the assembled state of the push element on the guide rail. The height adjustment element, which is preferably in the form of an annular disk, has, for example, a continuously changing thickness over the extent of the section effective in the possible adjustment positions in the different pivot positions. The height adjustment element is accordingly preferably wedge-shaped with a minimum thickness at a z. B. free front end of the height adjustment element and a maximum thickness at the opposite end of the height adjustment element. Depending on the pivoting or rotating position of the height adjustment element, a different section of the height adjustment element becomes effective and thus a different thickness of the height adjustment element between For example, a contact surface on the thrust element and an opposing contact surface on the guide rail are moved or pivoted into the area between the contact surfaces. Depending on the pivot position of the height adjustment element or depending on the effective thickness of the wedge section of the height adjustment element, the vertical distance between the contact surfaces is changed. The contact surface on the guide rail is fixed in position, so that the push element can be adjusted vertically, with simultaneous support or support via the height adjustment element on the contact surface of the push element. The height adjustment element or its wedge section is provided in such a way that the height adjustment element, on the one hand, or on the underside, comes into contact, preferably against an upper side of the guide rail and, on the upper side, comes into contact with an underside of the thrust element. With the pivoting, the height adjustment element forces itself, moving horizontally, between these two contact surfaces. In the use state, the pivoting is preferably carried out around a vertical or perpendicular spatial axis. The push element lies in the front area of the push element rail and can be lifted vertically upwards on the upper side of the guide rail, under the effect of the dead weight and a load weight. Depending on the rotational position of the height adjustment element and thus on the effective section of the wedge section with the associated wedge thickness of the height adjustment element, when the height adjustment element is pivoted in a pivoting direction, the thrust element is offset upwards or downwards relative to the guide or thrust element rail, with the opposite pivoting direction. The upward adjustment is a pushing up and takes place under overcoming the own weight of the pushing element. Lowering the thrust element does not require any effort, due to the weight of the thrust element. The push element always remains supported on the guide rail, the height adjustment element being present in between or sandwiched between the two contact surfaces on the push element and the guide rail. Only in a minimum or passive position of the height adjustment element on the This connecting device is not present in an inter-engaging manner between the contact surfaces on the thrust element and the guide rail, but rather is present or pivoted in at least substantially within an outer shape of the basic component.

Since the connecting device is mounted essentially next to the longitudinal side of the guide rail when in use, preferably in the front end area of the guide rail, the height adjustment element is present on the device in the maximum swiveled-in minimum position and is therefore not effective in changing the distance. The height adjustment element does not reach into the horizontal gap area between the underside of the thrust element and the upper side of the guide rail. The bottom of the sliding element rests directly on the top of the guide rail. The adjacent contact surfaces, in particular the underside of the sliding element and the upper side of the sliding element guide rails, are preferably aligned horizontally and parallel to one another when in use.

The wedge thickness varies over the extent of the height adjustment element, preferably z. B. between 0.1 millimeters at the free end of the wedge section and, for example, about 3 to 5 millimeters at the other end of the wedge section, which is forced between the contact surfaces in a maximum pivot position of the height adjustment element. This allows the pushing element underside and thus the pushing element to be maximally z. B. by about 3 to 5 millimeters in the vertical height on the furniture or relative to the fixed guide rail in the vertical direction, lifting by pivoting the height adjustment element in the other direction is reversible and thus the pushing element can be lowered again or any intermediate positions possible are. Depending on the design of the slope of the wedge section, other desired maximum adjustment values can be realized. In principle, a discontinuous or non-linear z. B. curved or stepped training of the Incline of the wedge section not excluded.

With the adjustment means according to the invention, a user-friendly, finely adjustable height adjustment of the thrust element is made possible. Over the entire possible adjustment path of the height adjustment element or z. B. the total possible angle of rotation of the rotary movement of the height adjustment element pushes it in a wedge shape between the relevant contact surfaces and thus, depending on the maximum thickness of the section of the wedge or height adjustment element in between, the distance between the contact surfaces and thus the height position of the thrust element to the guide rail or respectively on furniture. Since the height adjustment element preferably comprises an opposite second wedge side running obliquely to a flat first wedge side which is horizontal in the use state, the distance between the contact surfaces can be changed continuously. The height adjustment of the thrust element, on the other hand, is usually carried out with a small number of steps that is negligible in practice, depending on the distances between adjacent locking teeth and thus on the locking distance of the locking that can be set up with the locking element and the respective next or previous locking tooth of the locking teeth. The spacing of the ratchet teeth and the slope of the wedge section of the height adjustment element are coordinated, for example, in such a way that the vertical or height adjustment of the thrust element can be carried out in comparatively small steps of preferably approximately 0.5 to 1.0 millimeters.

In the assembled state, the first horizontal wedge side of the height adjustment element is preferably in contact with the contact surface of the thrust element or its underside over the entire swivel angle covered when the height adjustment element is swiveled. The vertically opposite, inclined, second wedge surface, which is spaced apart from the first wedge surface over the wedge thickness, can be rotated freely to sections of the device in the pivoted-in state, that is to say past these sections without contact or friction. The sloping wedge surface comes in the swiveled-out state preferably in contact with the contact surface or the top of the guide rail.

The maximum angle of rotation of the height adjustment element that can be swiveled back and forth reversibly as desired, which is determined between stops for the height adjustment element and / or the locking member on the connecting device, is preferably about 80 to 100 degrees, preferably about 90 degrees.

In particular, the locking means are provided so that when the pushing element is used, unavoidable static but especially dynamic effects such as vibrations of the pushing element or the guide system do not prevent any unwanted or automatic adjustment of the height adjustment element and thus the height position of the pushing element on the furniture or household appliance .

The adjusting means for adjusting the height of the thrust element on the furniture or on the household appliance or the control element, such as. B. a control lever with a pressure surface, are preferably easily accessible and operated by a person in the fully assembled state of the pusher element on the furniture or household appliance, although advantageously not visible from the front or from an operating side in the use state, but concealed by the pusher element. The connecting device is therefore preferably positioned adjacent to a rear side of a front element of the pushing element or thus in the front end region of the guide system or the pushing element guide rail, for example screwed to the pushing element base and / or the front element. The front end of the push element guide rail usually reaches up to or close to the front element, so that the control element can be easily reached from the front of the furniture by reaching under a lower edge of the front element with the hand. For good operation, the operating element is preferably designed in a haptically advantageous manner, for example with roughening or corrugation on the outside.

For the height adjustment it only has to be ensured that the underside of the pushing element is accessible from below in its front end area for manual operation of the adjusting means or the operating element. For this purpose, the pushing element is, for example, pulled out a little towards the front from the position fully retracted on the furniture or from the closed position. The sliding element rail is then slightly or relative to a body rail or center rail shifted or lengthened compared to the pushed together guide system.

The person can then access the connecting device on the pushing element protruding forward to a front plane of the piece of furniture, which takes place at the front on the underside of the pushing element. The control element can thus be operated manually, which is possible with a simple movement. The control element is preferably adjustable without any noticeable expenditure of force and by a comparatively short adjustment distance, for example in the millimeter range or in millimeter steps up to, for example, about 30 millimeters based on a circumferential line of the control element to the pivot axis of the height adjustment element, which is preferably carried out with the swivel or. Adjustment axis of the control element coincides.

The guide rail is for example or preferably a sliding element rail, in particular a drawer rail of a partial or full extension with telescopic guide rails.

More specifically, the invention relates in particular to a furniture-drawer connecting device or a household appliance-drawer connecting device.

With the connection device, for example, a front image on a piece of furniture or household appliance can be finely adjusted, as far as horizontal positions on the furniture are concerned, with which, in particular, a uniform joint pattern on the Furniture or household appliance is possible. This is because, with two or more sliding elements on a piece of furniture, their vertically adjacent horizontal edges of a sliding element front side are often present in the millimeter range in the vertical direction, different from neighboring horizontal edges on the piece of furniture. This is undesirable for optical or aesthetic reasons. A non-horizontal edge course can also be remedied by using the adjustment means of the connection device on the left structural unit of the guide system on the push element and the adjustment means on the right structural unit of the guide system on the push element in such a way that the push element is aligned horizontally. With the height adjustment of the pushing element, with guide system modules usually present on two or both sides at the bottom or on the side of the pushing element, the front image on the furniture can be set uniformly above and / or below a pushing element, based on a uniform front column with a uniform vertical gap width the relevant horizontal edge of the adjacent sliding element or other horizontal edges of furniture when aligned exactly parallel to the horizontal.

The connecting device preferably has locking coupling means with which the connecting device, in particular when attached to the thrust element, can be coupled in a locking manner to a mating contour that is present on the guide rail of the guide system or an intermediate piece, so that a locking coupling for a secured but detachable and correctly positioned connection of the thrust element is provided on the guide system. The connecting device according to the invention is therefore preferably designed, in particular, as a height adjustment latching coupling.

It is also advantageous that the height adjustment element, the operating element and the latching element are designed in one piece. With such an adjusting component 54, the connecting device according to the invention can be produced in an economically advantageous manner. The adjusting component 54, which can for example be detachably plugged onto a basic component of the device, has, for example, in a Area around the pivot axis around a central section which is connected to the height adjustment element and the operating element. The central area can comprise an annular area for encompassing a pivot axis element on the basic component. At the central portion is preferably a z. B. L-shaped elastically evasive organ or a spring organ or elastic organ for receiving the control element is available, which is described below.

A separate adjusting component 54 is preferably formed which has the height adjustment element, the operating element and the latching element. The adjusting component 54 and the basic component are preferably made of a plastic material or are each an injection molded part. The connecting device preferably comprises exactly two one-piece components that can be plugged together for completion, the base component and the control component 54. The base component and the control component advantageously each have a different color, the base component, for example, light gray and the control component green. Further functionalities are preferably present on the basic component, such as fastening means for attaching the connecting device to the pushing element and the guide rail in the correct position.

In addition, it is advantageous that the locking teeth are arranged along a conical surface. The conical surface is to be understood in the geometric sense as the conical surface. This is advantageous for a compact design and a mechanically reliable locking. The locking teeth on the conical surface are advantageously formed in one piece with the latter. The respective tip or each grid elevation of a locking tooth preferably runs along an associated surface line of the relevant cone. The conical surface is formed, for example, by an outside of a cone or a truncated cone. In particular, the locking teeth are designed along a conical surface. The conical surface is preferably a partial circumferential surface of a conical surface.

The locking teeth are preferably designed like webs or ribs, the webs or ribs of which are each linear and similar to one another on the conical surface.

The ratchet teeth have raised ratchets and ratchet depressions, which are designed alternately or alternately next to one another on the conical surface circumferentially to the axis of rotation of the height adjustment element. For example, 15 to 20 increments are provided for the axis of rotation of the height adjustment element over an angular range of approximately 90 degrees and a recess in each case between two adjacent elevations. With the exception of preferably at least one retaining tooth of the ratchet teeth, such as a first and / or last ratchet tooth in the row of ratchet teeth, preferably all of the ratchet teeth are designed to be similar or identical to one another. This is advantageous for a z. B. positive connection of the one locking member with each of the locking teeth.

The latching element which can be latched with the latching teeth or engages in the latching teeth preferably has a ratchet elevation and, on both sides thereof, latching element flanks that delimit the ratchet elevation. The raised grid and the locking element flanks are designed in such a way that in a locked state of the locking element with a portion of the locking teeth, the locking element engages appropriately and rests flat on the surfaces of the raised grid and the locking recess of the tooth contour of the associated or relevant locking tooth.

The latching member preferably has the matching counter-shape of a latching recess of the latching teeth formed between two raster heights.

Accordingly, it is advantageous that in the locked state Latching organ flanks of the latching organ fit into a latching recess of the latching teeth in surface contact.

The locking teeth are advantageously arranged next to one another in a row. The ratchet teeth are arranged along the contour of the jacket surface, which is circular in cross section of the jacket surface. The lateral surface preferably has an extension or depth which is axial to the axis of rotation of the height adjustment element, over which the locking teeth are preferably formed continuously over their length axial to the pivot axis.

It is also advantageous that the latching teeth have latching surfaces, the latching surfaces including a latching angle, the latching angle of the latching teeth being identical. The locking angles, preferably of all locking teeth, are identical to one another. In particular, a toothing or a helical toothing profile is provided, for example in the manner of a sawtooth profile. A locking tooth accordingly has tooth flanks that converge and merge into a locking tooth tip. The ratchet tip forms the end of the grid increase. The latching surfaces form sections or flanks of the raster heights or the latching depressions of the ratchet teeth.

With the identical detent angle z. B. of all locking teeth, it is advantageously possible that regardless of the selected locking position of the locking member always a locking is achieved with a maximum locking effect between the locking member and the respective section in question in the row of locking teeth. The latching angle is, for example, between 40 and 60, preferably 50 degrees.

An advantageous modification of the invention is given by the fact that the locking teeth comprise a retaining tooth, the shape of the retaining tooth differing in each case from the shape of the remaining locking teeth. The remaining ratchet teeth are preferably identical to one another. Advantageously, the retaining tooth is for comparatively stronger locking of the locking member in z. B. a transport position of the device such as provided for a delivery state of the device to a customer. In particular, in the transport position, the height adjustment is not in an operative position or in the minimum position in which the height adjustment element is in a position on the connecting device that has been pivoted to the maximum extent.

The retaining tooth is designed in such a way that, compared to an operating and adjusting force which is necessary to cancel a latching position of the latching element with one of the remaining latching teeth, the unblocking of the latching element on the holding tooth is higher. The latching of the latching member in the transport position can thus only be canceled with a comparatively greater expenditure of force or a greater latching resistance is set up.

A latching surface with two different latching surface sections is preferably provided with the retaining tooth. The two locking surface sections form the opposite flanks of the retaining tooth, the two flanks converging in a tip of the retaining tooth.

Preferably, one of the two locking surfaces on the retaining tooth has two differently oriented straight locking surface sections. The surface normal of the one locking surface section is different from the surface normal of the other locking surface section or the two locking surface sections each have a different slope.

A latching surface section advantageously forms an angle with the further latching surface of the retaining tooth which is identical to the latching angle of the remaining latching teeth.

The retaining tooth is particularly slightly z in the radial direction to the axis of rotation of the height adjustment element. B. by approx a millimeter or a fraction of a millimeter longer than the remaining ratchet teeth. The tip of the retaining tooth is accordingly spaced more radially from the pivot axis than the respective tip of the remaining ratchet teeth.

Another advantageous embodiment of the invention results from the fact that the locking teeth are arranged in a row next to one another, the retaining tooth being arranged in the row on an outside. The retaining tooth is thus a first and / or last tooth in the row of all ratchet teeth. The retaining tooth is accordingly preferably provided at the beginning of the latching area with the latching teeth, in particular at a first and / or last point of the latching teeth at which a first or last latching position or latching with the latching member is possible. This corresponds e.g. B. the position of the height adjustment element in which the height adjustment element is not effective. In this position, based on the assembled state of use, the height adjustment element does not engage between the contact surface on the thrust element and the contact surface on the guide rail. The height adjustment element is swiveled in and thus passivated in its lifting effect to increase the height position of the thrust element.

It is also advantageous that a first locking surface of the locking teeth, viewed in a first adjustment direction of the locking member, has a greater slope than a slope of the second locking surface of the locking teeth, viewed in a second adjustment direction of the locking member. It is thus possible to achieve a particularly manual adjustment of the locking member and thus of the height adjustment element in the second adjustment direction in a comparatively simpler or easier way than is the case with the adjustment in the first direction. The locking surfaces of a locking tooth form, on the respective side of the locking tooth, in particular a stop for the locked locking member. In order to bring a locking element in the locked state between two grid heights of adjacent locking teeth out of the locking and into the first To move the adjustment direction, an increased force must be applied compared to the force to be applied, which is necessary for bringing the locking member out of the latching and moving it in the second adjustment direction. With the greater slope of the relevant locking surfaces of the locking teeth, an increased resistance to bringing the locking member out of a locking position in the first adjustment direction is realized compared to the resistance to moving the locking member from a locking position in the second adjusting direction.

For example, an adjustment of the locking member in a first direction can be made more difficult, which is favored, for example, due to the acting weight of the thrust element in the use state, as far as an automatic or unwanted adjustment is concerned. A greater slope of the relevant locking surface and thus a higher adjustment resistance in this direction counteracts an automatic adjustment of the locking member.

It is also advantageous that a locking surface of a locking tooth in particular forms a stop for the locking member. This enables the locking member to be locked onto the locking teeth in a simple manner. The latching element and the latching surface of each latching tooth are preferably coordinated in such a way that a self-locking planar contact of sections of the latching element and the latching surface is made possible in the latching state.

Basically, the height adjustment element is designed in such a way that it has an increasing or decreasing thickness in the direction of extent, preferably has a continuously increasing or decreasing thickness. The changing thickness relates at least to that part of the height adjustment element which can be brought between the contact surface of the thrust element and the contact surface of the guide rail in part or over the entire extent by pivoting or rotating the height adjustment element.

Basically, the height adjustment is an alternative to the Pivoting or rotating the height adjustment element, a linear movement of the height adjustment element or a superimposed linear and non-linear type of movement of the height adjustment element are also conceivable.

An advantageous modification of the invention is characterized in that the height adjustment element is in the form of a circular disk, in particular in the form of a partial circular disk, the thickness of the circular disk increasing or decreasing along a circular path around the pivot axis of the height adjustment element. The height adjustment element is preferably designed in the form of a wedge-shaped partial ring disk or partial ring circular disk. The partial ring disk is formed over a circumferential to the pivot axis of the height adjustment element over an angular range of preferably about 90 degrees and in the radial direction from an inner radius spaced from the axis of rotation to an outer radius, so in the form of z. B. a quarter circular ring or a partial circular ring. At the front free end of the height adjustment element, the thickness of the height adjustment element is minimal and at the other end of the height adjustment element in the circumferential direction to the pivot or rotation axis, the thickness of the height adjustment element is maximal.

It is also advantageous that the operating element has an elastic element, the operating element being connected to the height adjustment element via the elastic element.

The latching member is preferably present on the operating element. So that the locking member is resiliently mounted on the device.

The latching element is preferably elastically pretensioned in the latching direction or urged with a spring force in the direction of contact with the respective section of the latching teeth, preferably under the action of the elastic element. The latching member can via the elastic member or via spring means for providing a spring force, such as a resilient arm, on a remaining portion of the Adjusting means be included. A resilient mounting of the locking element is preferably set up with the spring means, which is designed in such a way that the locking element can be brought out of a pretensioned locking position on the locking teeth realized by means of the spring force by external pressure on the operating element in the direction against the effective direction of the spring force. Then the pivoting or rotating adjustment of the locking member is possible. When the height adjustment is complete and the pressure on the operating element no longer acts from the outside, the latching position in the newly established latching position of the latching element is set up immediately and automatically or against adjustment due to the biasing or spring force permanently acting on the latching element secured.

The arrangement is coordinated in such a way that the latching element forcibly comes into precisely the selected adjustment or latching position on the latching teeth without any external force being applied to the operating element. After removing the externally acting operating or adjusting force on the operating element, a comparatively very short distance of z. B. traveled 0.5 to 1.5 millimeters of the locking member. This path corresponds to the path that was previously overcome manually by the operator. The locking element moves back resiliently from the non-locked position according to the newly selected rotational position of the height adjustment element into the new position of the locking element between the locking teeth, so that the locking element is then locked again.

According to the invention, the control element is provided offset in the direction of the axis of rotation of the height adjustment element to a surface of the height adjustment element, the control element being movable relative to the axis of rotation of the height adjustment element. The operating element has two directions of movement or degrees of freedom, first of all via the elastic member of the radial relative position to the pivot axis, and secondly via the pivot bearing of the adjusting component 54 about the pivot axis or the pivot axis. Can be swiveled back and forth extensively for the actual height adjustment. Preferably, the operating element is present in parallel to the axis of rotation of the height adjustment element protruding from a surface of the height adjustment element, the operating element being present so as to be movable in a direction towards the surface and / or away from the axis of rotation. This enables the locking member to be adjusted with short adjustment paths in a space-saving manner.

Finally, the invention relates to a piece of furniture or a household appliance such as a kitchen appliance with a device according to one of the above-mentioned configurations.

In this way, the advantages mentioned above can be implemented on a piece of furniture or household appliance. In the case of the furniture, the sliding element is, for example, a drawer. In a household appliance such as a kitchen appliance such as an oven, the pushing element is, for example, a food support or a storage rack.

In the following, the same reference numerals are used in some cases for corresponding elements of different exemplary embodiments.

Figure 1 shows, in a highly schematic manner, a piece of furniture 1 according to the invention in a use state with a hollow cuboid furniture body 2 and a push element designed as a drawer 3, the drawer 3 being slidably received on the furniture body 2. The furniture carcass 2 comprises two opposite vertical side walls 4 and 5, between which the drawer 3 is in a horizontal position via a guide system according to the invention with telescopic guide means or a first fully extending rails 6 and a second fully extending rails 7 from a state housed in the interior of the furniture carcass 2 Direction from the furniture body 2 according to P1 can be pulled out and pushed in in the opposite direction according to P2. In Fig. 1 the drawer 3 is shown in the maximally or completely moved out of the interior of the furniture body 2. The storage volume of the drawer 3 can thus be accessed almost unhindered from above.

If the drawer 3 uses a partial extension rail instead of the full extension rails 6, 7, the drawer 3 cannot be moved as far out of the interior of the furniture body 2 in the direction P1 as it can with the full extension rails 6, 7 as shown in Fig. 1 is possible. The front element 12 is then closer to the open front side of the furniture body 2 than is the case with the drawer 3 according to FIG Fig. 1 is shown.

The full extension rail 6 screwed on the inside of the side wall 4 is opposite at the same vertical height as the one screwed on the side wall 5 in Figure 1 concealed rails full extension 7, which is indicated by dashed lines.

In the furniture carcass 2, a further drawer, which is appropriately guided via full-extension rails 8 and 9, can be accommodated above the drawer 3, which is shown in FIG Figure 1 is not shown.

The drawer 3 has opposite drawer side walls 10, 11, each of which comprises a built-up hollow chamber frame. In addition, the drawer 3 comprises a front element 12, a rear wall 13 opposite in the horizontal direction and a horizontally extending drawer bottom 14, which reaches or is connected to the drawer side walls 10, 11, the front element 12 and the rear wall 13.
