Description

Panel structure for drawer

Technical Field

The present invention relates to a panel structure for a drawer according to the preamble of claim 1 and to a drawer having such a panel structure.

Background

A related type of panel structure is known from DE 202008011505 a 1. The panel structure disclosed in this document comprises a panel base and a panel attachment with two supports which are placed on the panel base and each laterally enclose the edges of a surface element of a frame support, for example in the form of a U. Thus, the surface element itself is well supported. The known construction has thus proven itself, but improvements are still needed, in particular with regard to the usability, in particular on relatively narrow panel structures.

Achieving this object is the object of the present invention.

Disclosure of Invention

The invention achieves this object by the subject matter of claim 1. The invention also provides a drawer for a piece of furniture, having one or more panel structures according to one of the claims relating thereto.

Advantageous embodiments of the invention can be inferred from the dependent claims.

The following subject matter is provided according to claim 1: a panel structure for a drawer comprising a panel base and a panel accessory placed thereon, the panel accessory comprising at least the following features: two support assemblies and at least one surface element, wherein the two support assemblies each comprise a receiving channel with a U-shaped cross section on its side facing the surface element, wherein a corresponding first edge or second edge of the surface element engages in each of the receiving channels, respectively, wherein one or both of the support assemblies are formed as a corner device, wherein one support assembly can be fastened on the panel base and on the front panel. This construction is simple, stable and can be easily and well mounted in a labor-saving manner. Since the two support assemblies are then formed as a corner device, the mounting on the panel base is simplified, since the fastening on the panel base can be carried out in a simple manner. The support assembly rests on the vertical upper edge region of the panel base and, in the context of measures of more complex design, does not have to be inserted into the cavity of the panel base to achieve sufficient stability of the connection between the support and the base.

It may be conveniently provided that one support assembly is fastenable to the panel base and to the front panel and is designed as a corner device: this assembly is also referred to hereinafter as a front panel support assembly. According to another variant, another support assembly can be fastened on the panel base and on the rear wall and can also be designed as a corner device: this assembly is also referred to hereinafter as a rear wall support assembly. Each of these constructions is also particularly simple and stable and can be easily and well mounted in a labor-saving manner.

In order to ensure a good appearance and static balance, it is advantageous if the frame base bracket between the panel base and the surface element rests on the vertical upper edge of the panel base, and if the frame base bracket is located between two support assemblies, which are thus arranged at both ends of the frame base bracket. In order to achieve these advantages and in order to achieve good mounting capabilities, it is also advantageous if, according to a further variant, the panel base comprises a receiving channel at its top side, in which receiving channel one or more mounting elements are arranged or formed, and the frame base bracket associated with the panel base is an attachment bracket attached on the panel base, which is fastened to the panel base using a mounting device, which is designed to correspond to the mounting elements of the panel base. The frame base support may also extend with its side walls/edges across the entire length of the panel attachment and may have grooves in the end regions, each groove penetrating both supports.

Furthermore, it can be provided in an advantageous and space-saving manner that the mounting element of the frame base is arranged in its receiving channel. According to an advantageous optional refinement which further simplifies the installation and also optimizes the static balance, it is advantageous if the frame base bracket comprises a slot which is formed open in the opposite direction to its receiving channel and if elements of the receiving channel of the panel base and/or the support assembly, in particular the corner legs of the corner device, engage in this slot.

In the sense of an advantageous static balance and also an appearance, it is also advantageous if the frame base bracket projects vertically, with the vertically extending walls above the top edges of the receiving channel of the frame base, or with these walls of the frame base bracket lying entirely vertically above these edges.

According to another optional refinement, the front panel support assembly and the rear wall support assembly may each comprise as a corner device a horizontal corner leg which is placed on the frame base and a vertical corner leg which is perpendicular to the horizontal corner leg, the vertical corner leg comprising a respective receiving channel and being fastened directly or indirectly on the front panel or on the rear wall. According to another advantageous development, the corner device of the front panel support assembly may comprise fastening and supporting corners and vertical frame brackets covering them. Alternatively/optionally, the corner means of the rear wall support assembly may comprise fastening and supporting corners and vertical frame brackets covering them. These improvements can also be installed simply and well and additionally help to ensure good installation and good static balance.

It is advantageous at least in the sense of a good appearance and possibly also other functions if the corner means of the front panel support assembly and/or the corner means of the rear wall support assembly each comprise an external covering element which substantially or completely covers the fastening and support corners and/or the vertical frame brackets.

It can then also be provided according to a further advantageous variant which saves material and which can also be realized in a simple manner that the respective fastening and support angles in turn comprise a horizontal leg and a vertical leg, wherein the horizontal leg and the vertical leg preferably each have an L-shaped cross section completely or at least in sections, the webs or the corner walls being aligned at an angle with respect to one another, the horizontal leg and the vertical leg supporting the surface element directly or indirectly only in the L-shape. The L-shape is a significant constructional simplification in relation to the known U-shape for the fastening element, which forms the fastening and support corners, which enables a narrow panel structure construction, since the second long leg on the U-shape on the element (which typically consists of sheet metal) can be omitted and thus a very narrow design can be achieved. Furthermore, this feature may also save material.

Furthermore, it is advantageous in the sense of a good static balance and a simple installation capacity if the horizontal legs of the respective fastening and support angles are each fastened on or in the receiving channel of the frame base and/or if a vertical frame support is mounted on the vertical legs of the respective fastening and support angles, which vertical frame support covers the vertical legs and comprises a receiving channel for the corresponding vertical edge of the surface element that is U-shaped in cross section towards the surface element.

Furthermore, it is advantageous if the vertical frame supports and/or the fastening and support corners, respectively, are fastened directly or indirectly on the front panel or the rear wall, for example using a screw connection and/or a catch connection.

According to a further advantageous variant, which can likewise be used as an improvement, but also as a separate invention, it is provided that the vertical frame supports and the fastening and supporting corners of the rear wall support assembly can be fastened to the rear wall using at least one fastening means which can alternatively be used as a screw connection or a catch connection. Drawers with various rear wall types (e.g., made of wood or sheet metal) can be realized in this manner using the same panel attachments.

According to a further advantageous variant, which can likewise be used as an improvement but also as a separate invention, it is provided that the vertical frame support extends in the vertical direction beyond the surface element, and that a fixing element is provided which fixes the surface element in the Z-direction on the vertical frame support. The securing element is preferably secured against release from the vertical frame support using a covering element that at least partially covers the vertical frame support.

The fixing element can preferably also be an integral part of the respective fastening and support corner. This has the following advantages: the fastening by means of the covering element is not absolutely necessary.

In this case, the fixing element can be designed in a simple manner as a pin or plate, in particular a metal plate or a plastic plate, which can be inserted into a corresponding recess, in particular a slot, of the vertical frame support above the surface element.

According to a variant, the frame base support may be provided between two support assemblies which are arranged on the panel base and below the surface element, and they may have a receiving channel on the side facing the surface element, the receiving channel having a likewise approximately U-shaped cross section, wherein the corresponding further edge of the surface element engages in the receiving channel, so that the frame base support and the two support assemblies together in the mounted position form a non-peripherally closed approximately U-shaped frame on the panel structure. In summary, it is advantageous if, in particular, the resistance torque of the surface element against deflection or damage is to be counteracted, so that in the case of long panel lengths of sensitive material or in the case of surface elements or profiles having only a low resistance torque against deflection, the dissipation of forces is further optimized in this way and the surface element is well protected against loads and thus possible damage therewith. In addition, the stent provides visual advantages and options. The frame base support can be designed as an extrudable profile according to one variant.

The invention is suitable in that the surface element also has at the lower edge a protruding support, particularly but not exclusively for use on a panel structure, wherein the panel base is constituted by an inner shell and an outer shell, preferably made of steel sheet, which together form a body of substantially rectangular cross-section, the maximum width B of which₃Less than 20mm, preferably less than 15 mm.

Further advantageous embodiments of the invention can be deduced from the dependent claims.

Detailed Description

Fig. 1 shows a piece of furniture designed as a piece of cabinet-type furniture 2. The cabinet-type furniture 2 includes a furniture main body 3. Three drawers 4, 5 (by way of example only) are here inserted into the furniture body 3. The drawers 4, 5 are displaceably guided in the furniture carcass 3, so that each of the drawers 4, 5 can be pulled out of the furniture carcass 3 into an open position and can be pushed back from this position into a closed position.

The drawers 4, 5 each have a

front panel

6a, 6, wherein the front panel 6 of the lower drawer 5 is each designed as (as an example) a relatively high front panel 6, and wherein the front panel 6a of the upper drawer 4 is designed as a flatter front panel 6 a.

A part of the lower drawer 5 from fig. 1 is shown as an example in fig. 2. The drawer 5 comprises two side panel structures (in the following also referred to simply as panel structures 1). Only one of these panel structures 1 is shown in fig. 2. It also comprises a (relatively high) front panel 6, a rear wall 7 and a bottom panel 8 (see fig. 4). Furthermore, it may also have further elements (not shown here or not visible in the figures), for example a pull-out guide. Since the front panel 6 is relatively high, it is also desirable to be able to achieve a relatively high panel structure in a simple manner.

For orientation and simplicity of discussion, a coordinate system is depicted in FIG. 2. It should not be considered limiting, but rather illustrative. Thus, the front panel 6 extends substantially flat in the Y/Z plane, and the panel structure extends in the X/Z plane. The Z direction is also referred to as "vertical" depending on the typical use position of the drawer. In contrast, the X-direction and the Y-direction are referred to as "horizontal", wherein these designations relate to the typical mounting positions mentioned. These terms should not be construed as absolute limitations. If these terms are used in this document, they mean that the corresponding locations are provided in a horizontal orientation of the drawer with the lower bottom panel and the vertically aligned front panel.

Since the front panel 6 is relatively high in the vertical direction, it is desirable and advantageous to also make the panel structure relatively high.

The panel structure 1 comprises a panel base 9. Its main plane is the X/Z plane. The multi-part panel base 9 forms a lower part of the panel structure 6 relative to the bottom panel 8. A multi-part panel attachment 10 is attached to the panel base 9. The panel attachment 10 serves to extend the panel structure 1 vertically upwards in its main extension direction on the side of the drawer facing away from the bottom panel 8 and/or to provide a relatively high panel structure as a side wall of the drawer.

The panel attachment 10 comprises a plurality of single-part or multi-part basic construction elements and construction units. In this case, these are the frame base support 100, the two

support assemblies

200, 300 and the at least one surface element 400.

A support assembly is fastened to the panel base 9 and to the front panel 6 and is designed as a corner device and is also referred to below as front panel support assembly 200. The other support assembly is fastened on the panel base 9 and on the rear wall 7 and is designed as a support assembly and is therefore also referred to as rear wall support assembly 300 in the following.

The major plane of the panel attachment 10 is also the X/Z plane. The panel attachment 10 forms a vertically upper part of the panel structure 6 relative to the panel base 9 and extends the panel base 9 substantially vertically upwards in its main plane.

The surface element 400 may be constructed of vastly different materials. It may for example be formed as a glass plate or a metal plate or a wood plate and may also be formed as one part or several parts.

In principle, the construction of the panel structure 1 is oriented according to DE 202008011505U 1, i.e. the concept of maintaining a lateral support placed on top of the panel base and enclosing each of the edges of the surface element in a U-shape. However, it is improved as described below.

The first improvement consists of the specific features of the following construction. According to this feature, the mounting position of the frame base support 100 and the two

support assemblies

200, 300 on the panel structure 1 together form an approximately U-shaped frame enclosing each of the edges of the surface element 400 in a U-shape.

For this purpose, the frame base support 100 and the two

support assemblies

200, 300 each comprise a groove or receiving

channel

101, 201, 301 on their side facing the surface element 400, which groove or receiving channel likewise has an approximately U-shaped cross section. Corresponding

edges

401, 402, 403 of the surface element 400 engage in each of the receiving

channels

101, 201, 301. The following features are known from DE 202008011505 a 11: the two

support members

200, 300 each have a groove or receiving

channel

101, 201, 301 which has an approximately U-shaped cross section on its side facing the surface element 400. However, the advantageous measure of the frame base support 100 also having such a receiving channel is not known from this document. The support of the surface element 400 is thus advantageously improved and the surface element is better protected against damage than in the prior art.

The frame base support 100 is arranged between the panel base 9 and the surface element 400. It is also centrally located between two

support assemblies

200, 300 arranged at both ends thereof.

The panel base 9 in turn comprises a receiving channel 11 extending on its upper side in the X-direction. The receiving channel 11 also has a U-shaped cross-section. One or more mounting elements 12 fixed on the panel base 9 may be distributed in the receiving channel 11. These mounting elements 12 can be designed, for example, as first catch or clip elements.

The panel base 9 furthermore comprises an upper contact surface 13 and two vertically projecting

edges

14, 15. Here, the contact surface 13 also forms a main side of the upper receiving channel 11 of the panel base 9.

The frame base bracket 100 is designed as an attachment bracket, in particular a profile bracket made of plastic or metal, in particular light metal, which is placed on the frame base 9. It is fastened on the upper side 13 of the panel base 9 using mounting means 102, which may be designed to correspond to the mounting element 12 of the panel base 9, i.e. for example as a second catching or clipping element 102. The mounting of the frame base support 100 can be achieved in this way simply and quickly. The frame base support 100 comprises a lower side 103 and two

side walls

104, 105 vertical thereto. In a typical mounting position of the drawer, one of the side walls 105 here has a slot 106 extending vertically from the bottom to the top. The preferred function of the slot 106 will be explained in more detail below.

The frame base bracket 100 projects vertically with its two vertically extending

walls

104, 105 above the

upper edges

14, 15 of the receiving channel 11 of the panel base 9, or as shown here, it is located completely above these

edges

14, 15. In this case, the

walls

104 and 105 are spaced parallel to each other and are arranged almost flush with the

edges

14 and 15 surfaces. In addition to its advantageous static function, the frame base support 100 also forms in this way a visually recognizable design element of the panel attachment 10.

The panel base 9 can be designed in a multi-walled configuration and can be formed so as to be hollow below the receiving channel 11, so that in particular mechanical parts can be accommodated therein, which mechanical parts comprise connecting fittings and/or

elements

14, 15 for fastening the panel base 9 on the front panel 6 or on the rear wall 7.

Since the frame base support 100 itself comprises the receiving channel 101, its walls, i.e. the

side walls

104, 105, may also be designed uniformly, so that the edges of the surface element 400 are instead accommodated in the receiving channel 101. It is therefore advantageous that the surface element 400 is not directly inserted into the receiving channel 11, as it may comprise protrusions or the like within the receiving channel and also comprise, for example, the mentioned mounting element 12. Furthermore, the advantageous appearance of the side panel structure thus results in this part of the panel structure 1 (see fig. 2), since the frame base bracket 100 preferably forms a visible frame section or frame bracket of the surface element.

The frame base support 100 preferably extends across the entire length of the distance between the

support assemblies

200, 300 in the main extension direction X of the panel structure 1. The frame base support stabilizes the surface element 400 as the frame base support 100 receives and holds the lower edge of the surface element. In particular, the frame base support secures the surface elements in a simple manner against deflection in the Y-direction.

The panel base 9 is connected to the front panel 6 using a connection fitting 16 (not shown here) and to the rear wall 7 using another connection fitting 17. Furthermore, the panel base 9 is preferably connected to the bottom panel 8 directly or indirectly via fittings (not shown).

One of the

support assemblies

200, 300 forming the vertical section of the U-shaped frame of the surface element 400 is placed on each of the ends of the frame base 9. For this purpose, the

support assemblies

200, 300 each comprise a receiving

channel

201, 301 on their side facing the surface element 400.

However, the two

support members

200, 300 not only have the above-described functions, but also are used in a multifunctional manner.

One of these support assemblies 200 is placed on the panel base 9 on the end of the panel structure 1 to which the front panel 6 is or will be attached. In its functional extension, the front panel support assembly 200 is connected to the panel base 9 and the front panel and in this way stabilizes the panel attachment 10.

To this end, the front panel support assembly 200 includes a first lower horizontal corner leg 202, such as a corner, and a vertical corner leg 203 perpendicular thereto. In the preferred mounting position shown in the figures, the main extension directions of the corner legs are the Y-direction and the Z-direction. The rear wall support assemblies may preferably be correspondingly identically configured.

The support assembly rests in this way on the vertical upper edge region of the panel base 9 and does not have to be guided into the cavity of the panel base 9 to achieve sufficient stability. The

support assembly

200, 300 is suitable because the surface element also has at the lower edge a protruding support, particularly but not exclusively for use on a panel structure, wherein the panel base consists of an inner shell and an outer shell, preferably made of steel plate, which together form a body of substantially rectangular cross-section. One of the cases, i.e., the outer case, is hidden in each of fig. 10 and 11.

Thus, it may be considered an improvement of the above-mentioned features or also as another advantageous feature of the independent invention to realise the angular shape of the support assembly 200 and/or 300. This feature also facilitates particular use also for narrow panel structures, due to the very good dissipation of loads and the simple way of arranging the

support assembly

200, 300 on the panel base 9.

The lower horizontal corner leg 202 may be placed on the panel base 10 and fastened using fastening means arranged in or fastened in the receiving channel 11 of the panel base 9. For this purpose, the screw 204 (see also fig. 8) can be used as a fastening means, for example thus in particular a screw with self-tapping threads. However, alternatively or optionally, corresponding fastening means may also be formed on the panel base 9 and on the horizontal corner legs 202, for example catching means.

Furthermore, the front panel support assembly 200 comprises a second corner leg, which in a preferred typical mounting position is designed as a vertical corner leg 203.

The vertical corner leg vertically comprises on its side facing the surface element 400 a receiving channel 201 of the vertical edge of the surface element 401. Furthermore, the vertical corner legs are fixed to the front panel 6, either directly or via fittings 205, on the side facing the front panel 6 facing away from the receiving channel 201.

In this way, the front panel support assembly achieves a stabilizing function by dissipating forces on the front panel 6 directly into the panel base 9 and by dissipating forces on the panel base 9 into the front panel 6 and the bottom panel 8. It protects the surface element 400 from loads and damage in this way.

The front panel support assembly 200 preferably includes a plurality of components for this purpose. The multipart construction enables the front panel support assembly to be optimally adapted to its various functions and to be mounted in a simple manner.

The components of the front panel support assembly 200 preferably comprise fastening and supporting corners 206 (fig. 7 to 13) and vertical frame brackets 207 (fig. 6 to 13) designed as first covers of the fastening and supporting corners 206 and covering elements 208 (fig. 13) provided as external covers. The fastening and support corners 206 (fig. 7 to 13) and the vertical frame brackets 207 may be assembled to form a mounting unit (fig. 15b, see also fig. 15 a).

The fastening and supporting corner 206 may preferably (see e.g. fig. 6a and 7) be composed of metal, in particular the fastening and supporting corner 206 is formed as a stamped/bent part composed of a plate, preferably a steel plate. In contrast, the vertical frame support 207 (see, e.g., fig. 6b and 7) may also be constructed of another material, preferably plastic.

The fastening and support corner 206 also includes a horizontal leg 209 and a vertical leg 210.

In this case, the horizontal leg 209 and the vertical leg 210 preferably each completely or at least partially comprise an L-shaped cross section, each having a

base wall

209a, 210a, here or preferably continuous, and a

corner wall

209b, 210b, here preferably discontinuous. The L-shape ensures the required stability of the support element in a simple manner.

The horizontal leg 209 of the fastening and support corner 206 here forms the entire horizontal corner leg 202 of the front panel support assembly 200 alone. In this case, the horizontal corner wall 209a of the fastening and support corner 206 is here inserted into the receiving channel 11 of the panel base 9 and fastened therein on its contact surface 13. This fastening can be performed, for example, using the above-mentioned screw 204, in particular using a screw 204 with self-tapping threads, which is screwed into the upper side or contact surface 13 of the panel base 9. Such screw tightening is stable and safe. Alternatively, such fastening may be performed by other means and/or in other ways, for example by riveting, welding or brazing. In this case, the horizontal leg 209 of the fastening and support corner 204 may itself advantageously have a channel, window or recess through which elements of the panel base (e.g. mounting means) may extend, thereby securing these elements of the frame base bracket 100 thereon, for example.

The corner wall 209b of the horizontal leg 209 abuts laterally on the inside on one of the

edges

14, 15 or the side wall of the receiving channel 11 of the panel base 9 or is inserted into the slot 106 of the side wall 105 of the frame base bracket 100, which further stabilizes the entire panel attachment.

In a state where the fastening and supporting corner 206 is mounted in the receiving channel 11 on the upper side of the panel base 9, the vertical leg 210 of the fastening and supporting corner 206 extends vertically upward. In order to be able to optimally accommodate the edges of the surface elements, vertical frame brackets 207 are mounted on vertical legs 210. This comprises receiving channels 201 (fig. 6, 7) for corresponding vertical edges of the surface element 400 (fig. 2) facing the surface element 400.

The covering vertical frame support 207 may be constructed of plastic. In this way it may be particularly optimally adapted to the task of accommodating the edge of the surface element 400. In this regard, it is also advantageous if the surface element 400 is inserted into the receiving channel 201 of the plastic part to protect the material and prevent loads and/or damage such as scratches, instead of on a metal bracket or the like.

The vertical frame bracket 207 may be fastened to the vertical leg 210 of the fastening and support corner 206 using a vastly different fastening means. Fixation by means of screws is preferred. However, alternatively or optionally, the use of corresponding catching and/or clamping means 211, 212 for fastening is also conceivable, since it can be realized simply and quickly. It may also be provided to provide one type of pre-mounting using corresponding catching and/or clamping means 211, 212 and additionally to provide a screw 213 for fastening to the front panel 6 for stabilization of the front panel support assembly (see also fig. 8 a).

If screws 213 are used, it is advantageous to screw them through

holes

214, 215 in the vertical frame brackets 207 or to screw the vertical legs 210 of the fastening and support corners 206 into the front panel 6 or into the fittings 205 of the front panel fasteners. The fitting 205 may comprise a plate 216, for example screwed onto the vertical leg 210 and preferably comprising a pin 217, in particular a pin that can be spread out to clamp in a bore of the front panel 6 or to connect fitting means to function in another way (fig. 8 and 9, 10 and 11 and 12). The pin 217 may be inserted into a hole of the front panel 6 and may be securely fastened therein by being unfolded. The plate 216 is preferably located in the free space 222 between the vertical frame bracket 207 and the front panel 6, remaining facing the front panel when the vertical frame bracket 207 is attached due to the protrusion 221 on this bracket (see also fig. 12).

However, the front panel fasteners or fittings 205 used to connect the vertical frame brackets to the front panel 6 may also be configured in another manner. It is necessary to connect the front panel support assembly 200 and the front panel 6 to each other well and reliably.

Near the upper end of the vertical frame support 207, it may extend slightly above the vertical height of the surface element, the surface element 400 being presented in a mounted state (fig. 8b, 8 c). In this way, it is possible to provide the fixing element 218, which vertically fixes the surface element 400, on the vertical frame support 7 itself. The fixing element 218 may be formed as a plate or a pin, in particular as a metal plate or a plastic plate, and it may be inserted into a corresponding recess, in particular a slot 219, of the vertical frame support 207 above the surface element 400 and fixed there using a covering element 208 (see fig. 8a, 8b, 8c and 13, and see also e.g. the covering element 208 of fig. 2).

The construction and installation of the preferred back wall support assembly 300 is described in more detail below.

The rear wall support assembly 300 is placed on the panel base 9 at the end of the panel structure 1 where the rear wall 7 is or will be attached (see fig. 3). In its functional extension, the rear wall support assembly 300 is connected to the panel base 9 and the rear wall 7 and in this way stabilizes the panel attachment 10.

According to a variation, the rear wall support assembly 300 may be substantially or entirely configured like the front panel support assembly 200, and may be secured to a rear wall (e.g., a wood rear wall (not shown here)) in a similar manner. In this regard, the above description is also fully understood in light of this variation of the rear wall support assembly 300, wherein the phrase "front panel" would be replaced by "rear wall".

In the configuration shown in the figures, the rear wall support assembly 300 is configured as a large component as the front panel support assembly 200. However, it is fastened in a different way to the rear wall 7, which according to the figure is a sheet metal rear wall.

The components of the rear wall support assembly 200 preferably include a fastening and support corner 306 (fig. 14 a-14 d), a vertical frame bracket 307 (fig. 14 a-14 b) formed as a first inner covering of the fastening and support corner 306, and a cover element 308 (fig. 2) provided as an outer covering.

According to an advantageous exemplary embodiment shown in the figures (without limiting the invention thereto), the rear wall support assembly 300 comprises a first lower horizontal corner leg 302 and a vertical corner leg 303 perpendicular thereto. The main directions of extension of these legs in the preferred mounting position shown in the figures are the X-direction and the Z-direction.

The lower horizontal corner leg 302 rests on the panel base 10. The horizontal corner legs 302 are here placed into the receiving channels 11 of the panel base 9 and fastened therein. For this purpose, fastening means such as screws 304 (as shown in fig. 13) may be used, for example screws with self-tapping threads and/or corresponding fastening means (e.g. catching means) on the panel base 9 and on the horizontal corner legs 302.

Further, the rear wall support assembly 300 includes a second corner leg, which in the preferred typical installation position is a vertical corner leg 303. It comprises vertically on its side facing the surface element 400 a receiving channel 301 of the vertical edge of the surface element 401. Furthermore, it is fixed to the rear wall 7, either directly or via a fitting 305, on the side facing the rear wall 7 facing away from the receiving channel 301.

In this manner, the rear wall support assembly 300 performs a stabilizing function by dissipating forces on the rear wall 7 directly into the panel base 9 and by dissipating forces on the panel base 9 into the rear wall 7 and the bottom panel 8. In this way, it protects the surface element 400 from loads and damage.

To this end, the rear wall support assembly 300 preferably includes multiple components. The multi-part construction enables the rear wall support assembly to be optimally adapted to its various functions and to be mounted in a simple manner.

These components preferably include a fastening and support corner 306 (fig. 14-18), a vertical frame bracket 307 (fig. 14-18) formed as a cover to fasten and support the leg 306, and a cover element 308 (fig. 17) covering the arrangement.

The fastening and support corner 306 (see e.g. fig. 6a and 7) may preferably consist of metal, in particular it is formed as a stamped/bent part from a plate, preferably a steel plate. In contrast, the vertical frame support 307 (see e.g., fig. 14b) may preferably be constructed of plastic.

The fastening and support corner 306 in turn comprises a horizontal leg 309 and a vertical leg 310.

In this case, the horizontal leg 309 and the vertical leg 310 preferably each have an L-shaped cross section completely or at least in sections, so that there is a

base wall

309a, 310a which is continuous in this case or preferably in each case and a

corner wall

309b, 310b which is preferably discontinuous here. The L-shape serves to enhance the stability and material savings associated with the U-shape. In addition, a narrow structure is also achieved.

The rear wall support assembly 300 here separately forms the horizontal leg 309 of the fastening and support angle 306 over the horizontal corner leg 302. In this case, the horizontal corner wall 309a of the fastening and supporting leg 306 is inserted into the receiving channel 11 of the panel base 9 and fastened there on its contact surface 13. This fastening can be carried out, for example, using the above-mentioned screw (similar to the screw 204, not shown here), in particular using the above-mentioned screw with self-tapping thread, which is screwed into the top side or contact surface 13 of the panel base 9. Such screw tightening is stable and safe. Alternatively, such fastening may be by other means and/or in other ways, for example by riveting, welding or brazing. In this case, the horizontal legs 309 of the fastening and support corners 304 may themselves advantageously have channels, windows or grooves through which elements of the panel base (e.g. mounting means) may extend, for example such elements on which the frame base bracket 100 is fixed.

The corner wall 309b of the horizontal leg 309 laterally abuts on the inside on one of the

edges

14, 15 or the side wall of the receiving channel 11 of the panel base 9 or is inserted into the slot 106 of the side wall 105 of the frame base bracket 100, which further stabilizes the entire panel attachment (not shown in detail here, which is similar to a front panel corner assembly).

In a state where the fastening and supporting corner 306 is mounted in the receiving channel 11 on the top side of the panel base 9, the vertical leg 310 of the vertical frame bracket 310 extends vertically upward. To be able to optimally accommodate the edges of the surface elements, the vertical frame support 307 is mounted on the vertical leg 310. This comprises receiving channels 301 (fig. 14) for corresponding vertical edges (fig. 2) of the surface element 400 facing the surface element 400.

The vertical frame support 307 may be constructed of plastic. In this way it may be particularly optimally adapted to the task of accommodating the edge of the surface element 400. In this regard, it is also advantageous if the surface element 400 is inserted into the receiving channel 201 of the plastic part to protect the material and prevent it from loads and/or damage, such as scratches, instead of on a metal bracket or the like.

The vertical frame support 307 may be fastened to the vertical legs 309 of the fastening and support corners using vastly different fastening members. For example, fastening by means of screws is conceivable.

However, it is preferred to fasten using corresponding catching and/or clamping means 311, 312, since this can be achieved simply and quickly.

One type of pre-mounting using corresponding catching and/or clamping means 311, 312 is provided, and additionally the stabilization of the back wall support assembly (not shown here) using a screw (such as using screw 213) for fastening of the back wall 7 may be provided.

A wide variety of fastening members may be provided for securing or fastening the rear wall 7 to the rear wall support assembly 300.

According to fig. 14 to 17, it is provided that one or more fastening means 321, 322 are used for this purpose on the rear wall support assembly 300. According to the exemplary embodiment shown, these fastening means can have catching

hooks

323, 324 which are formed on the side of the vertical frame support 307 oriented towards the rear wall 7 and which furthermore pass through the recesses of the fastening and support corners 306 and engage in the windows 18, 19 of the rear wall 7 (fig. 15a, 16) and lock therein. This type of installation can be carried out simply and quickly.

It can be seen that the

projections

325, 326 are formed between the catching hooks 423, 324 on the side of the vertical frame support 307 oriented towards the rear wall 7, which also pass through the recesses of the fastening and support corner 306 and engage in the windows 18, 19 of the rear wall 7.

In the case of mounting on a rear wall which then consists, for example, of wood or plastic, the

projections

325, 326 can be used for applying to this rear wall, wherein the fixing of the rear wall 7 on the

projections

325, 326 can then be carried out using the threaded rod 20 (see also fig. 18). This type of installation can also be carried out simply and quickly. In this way, the fastening means 321, 322 of the rear wall support assembly 300 can be used in a simple manner on the one hand for fastening on rear walls 7 with windows, in particular made of sheet metal (using catch hooks) or for fastening on rear walls, in particular made of wood (using screws in particular).

Near the upper end of the vertical frame support 307, it may also extend slightly above the vertical height of the surface element, which surface element 400 is presented in the mounted state (fig. 8b, 8 c). In this way, a fixing element, such as fixing element 218, may also be provided on the vertical frame support, which vertically fixes the surface element 400. The fixing element can likewise be formed as a plate, in particular as a metal plate or a plastic plate, and it can be inserted into at least one corresponding recess, in particular a slot 319 (fig. 16), of the vertical frame support above the surface element 400.

After mounting the frame base support 100, the support assembly and/or here the fastening and support

corners

206 and 207 and the surface element 400 on the panel base 9, the

cover elements

208, 308, e.g. the

U-shaped cover elements

208, 308 in side view, are preferably placed on the respective vertical frame supports 207, 307 and the respective fastening and support

corners

206, 306, respectively (see e.g. fig. 13), and may be placed on these elements in a clamping and/or latching manner and completely or partially hide them. In this way, a favorable appearance and good protection of the underlying element can be achieved by the covering element. The covering

elements

208, 308 may have edges 220, 320 which protrude towards one another on their ends facing away from the front panel 6 or the rear wall 7, respectively, so that the vertical frame support 207 is also well covered in this area.

The base angles 306, 206 are each preferably composed entirely or substantially of metal, in particular of steel, aluminum or die-cast zinc.
