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 panel structure of the type concerned 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 an edge of a surface element, such as a frame bracket or the like in a U-shape. Thus, the surface element itself is well supported. The known structures have thus proven themselves, but improvements are needed in particular with regard to their usability on relatively narrow panel structures.

Achieving this object is an 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 furniture, having one or more panel structures according to the claims relating thereto.

The dependent claims conclude advantageous embodiments of the invention. Providing a panel structure for a drawer according to claim 1, said panel structure comprising a panel base and a panel attachment placed on said panel base, said panel attachment comprising at least the following features: two support components and at least one surface element, wherein the two support components each comprise a receiving channel which in turn has a U-shaped cross section on their side facing the surface element, wherein a respective first edge or second edge of the surface element engages in each of the receiving channels, wherein a frame base bracket is provided between the two support assemblies, the frame base bracket being arranged on the panel base and below the surface element, and further comprising a receiver channel with a U-shaped cross-section on its side facing the surface element, engaging the respective other edge of the surface element in the receiver channel such that the frame base bracket and the two support assemblies together form a U-shaped, non-circumferentially closed frame on the panel structure in the installed position.

In other words, there is also provided a panel structure for a drawer, the panel structure comprising a panel base and a panel attachment placed on the panel base, the panel attachment comprising at least the following features: two support components and at least one surface element, wherein the two support components each comprise on their side facing the surface element a receiving channel again having a substantially U-shaped cross section, wherein a respective first edge or second edge engages in each of the receiver channels, wherein a frame base bracket is additionally provided between the two support assemblies, the frame base bracket being arranged on the panel base and below the surface element, and comprises a receiving channel which in turn has a substantially U-shaped cross section on its side facing the surface element, engaging the respective other edge of the surface element in the receiver channel such that the frame base bracket and the two support assemblies together form a substantially U-shaped, non-circumferentially closed frame on the panel structure in the installed position.

Overall, the dissipation of forces is further optimized in this way, and the surface elements are well protected against the load and thus from possible damage accompanying this load. This is particularly advantageous when it is desired to prevent the surface element from resisting flexing or damage, i.e. in the case of surface elements or contours with a large frame length, sensitive materials, or with only a small deflection resistance moment. Furthermore, this bracket provides visual advantages and options. The frame base carrier can be designed according to a variant as an extrudable profile.

According to a further advantageous variant, which can likewise be used as an improvement and also as a separate invention, it is also advantageously provided that the two support assemblies are formed as corner assemblies, whereby the mounting on the panel base is simplified, since fastening on the panel base is possible in a simple manner. The support assembly rests on the vertical upper edge zone of the panel base and does not have to be inserted in a structurally more complex manner into the cavity of the panel base in order to achieve sufficient stability of the connection between the support and the base.

It is convenient to provide that a support member can be fastened to the panel base and to the front panel and be designed as a corner structure: this assembly is also referred to hereinafter as a front panel support assembly. According to another variant, it can also be provided that a further support assembly can be fastened on the panel base and on the rear wall and is also designed as a corner structure: this assembly is also referred to hereinafter as a rear wall support assembly.

In order to ensure a good appearance and static balance, the following is advantageous: the frame base bracket between the panel base and the surface element is located on the vertical upper edge of the panel base and it is located between the two support assemblies, which are thus arranged at both ends of the frame base bracket. In order to achieve these advantages and achieve good installation capacity, the following is also advantageous: according to another variant, the panel base has a receiver channel on its top side, wherein one or more mounting elements are arranged or formed in the receiver channel, and the frame base bracket is opposite to the panel base an attachment bracket attached to the panel base, which attachment bracket is fastened to the panel base by using mounting members corresponding to the mounting elements of the panel base. The frame base bracket may also extend over the entire length of the panel attachment by its side walls/edges and may have recesses in the end regions, each penetrating the two supports.

In addition, it can be provided in a simple manner that the mounting element of the frame base is arranged in its receptacle channel.

According to an advantageous optional improvement that further simplifies the installation and also optimizes the static balance, the following is advantageous: the frame base bracket comprises a slot which is open formed in the direction opposite to its receptacle channel and in which an element of the receptacle channel, in particular a corner leg of a corner structure, of the panel base and/or of the support assembly engages.

In terms of favourable static balance and appearance, the following is additionally advantageous: the frame base brackets project vertically above the upper edges of the receiver channels of the panel base by vertically extending walls or are positioned entirely vertically above these edges by these walls.

According to another optional refinement, the front panel support assembly and the rear wall support assembly may each comprise as corner structures a horizontal corner leg placed on the frame base and a vertical corner leg perpendicular to the horizontal corner leg, the vertical corner leg comprising a respective receptacle channel and being fastened directly or indirectly on the front panel or on the rear wall.

According to another optional refinement, the corner structure of the front panel support assembly may comprise a fastening and support corner and a vertical frame bracket covering the fastening and support corner. Alternatively, the corner structure of the rear wall support assembly may include a fastening and support corner and a vertical frame bracket covering the fastening and support corner.

Then, at least in terms of good appearance and possibly also in order to perform other functions, the following is advantageous: the corner structure of the front panel support assembly and/or the corner structure of the rear wall support assembly each comprise an outer cover element substantially or completely covering the fastening and support corners and/or the vertical frame brackets.

Then, according to a further advantageous variant, which saves material and which can be implemented in a simple manner in addition, provision can be made for the respective fastening and support angles to in turn comprise a horizontal leg and a vertical leg, wherein the horizontal leg and the vertical leg preferably each have, completely or at least in part, an L-shaped cross section with webs or corner walls which are aligned at an angle relative to one another and which directly or indirectly support the surface element only in the L-shape. This L-shape is a significantly simplified structure compared to the known U-shape for the fastening element, which forms the fastening and support corners, which makes it possible to implement a narrow panel structure construction, since the U-shaped second long leg on this element, which is usually composed of sheet metal, can be omitted, and thus an extremely narrow design can be achieved. Furthermore, this feature may also enable material savings.

In addition, the following is advantageous in terms of good appearance and simple installation ability: the horizontal legs of the respective tightening and support angles are tightened on and/or in the receiver channels of the frame base and/or on the vertical legs of the respective tightening and support angles are mounted respective vertical frame brackets covering the vertical legs and comprising receiver channels for corresponding vertical edges of the surface element towards the surface element, the receiver channels having a U-shaped cross-section.

Then, it is furthermore advantageous that the vertical frame brackets and/or the fastening and support corners are fastened directly or indirectly to the front panel or rear wall, respectively, for example using a screw connection and/or a bayonet connection.

According to another advantageous variant, which can also be used as an improvement and as a separate invention, provision is made for the vertical frame brackets and the fastening and supporting corners of the rear wall support assembly to be fastened to the rear wall using at least one fastening means which can replace a threaded or bayonet connection. Drawers with various rear wall types, for example made of wood or sheet metal, can be implemented in this way using the same panel attachment.

According to a further advantageous variant, which can likewise be used as an improvement and as a separate invention, provision is made for the vertical frame carrier to extend in the vertical direction beyond the surface element and for a fixing element to be provided for fixing the surface element on the vertical frame carrier in the Z direction. Preferably, the fastening element is fastened against loosening from the vertical frame bracket using the cover element, which at least partially covers the vertical frame bracket.

The fixing element can preferably also be an integral part of the respective fastening and support corner. This has the advantage that: the fixing by means of the cover 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 as a metal plate or plastic plate, which can be inserted into a corresponding recess, in particular a groove, of the vertical frame carrier above the surface element.

The invention is suitable because the surface element also has excellent support at the lower edge, in particular, but not exclusively, for use on a panel structure in which the panel base consists of an inner and an outer shell, preferably made of steel sheet, which together form, in cross-section, a substantially rectangular body, 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 furniture 2. The cabinet furniture 2 includes a furniture main body 3. Merely by way of example, three drawers 4, 5 are inserted here into the furniture carcass 3. The drawers 4, 5 are displaceably guided in the furniture carcass 3, so that each drawer 4, 5 can be pulled out of the furniture carcass 3 in 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, for example, as 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 illustrated by way of example in fig. 2. The drawer 5 comprises two side panel structures, which are also referred to below simply as panel structures 1. Only one of these panel structures 1 is shown in fig. 2. The drawer 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 other elements, such as pull-out guides, which are not shown here or visible in the figures. Since the front panel 6 is relatively tall, a relatively tall panel structure is needed which can also be realized in a simpler manner.

To locate and simplify the 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 the "vertical" direction, depending on the typical use position of the drawer. In contrast, the X-direction and the Y-direction are referred to as "horizontal" directions, where these names refer to the typical mounting locations mentioned. These terms should not be construed as absolute limitations. If these terms are used in this document, it means that the corresponding location is provided with a horizontal orientation of the drawer having a lower bottom panel and a 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. The main plane of which is the X/Z plane. A multipart panel base 9 forms the 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 building elements and building units. In this case, these building elements and building units are the frame base carrier 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 structure and is also referred to hereinafter as a front panel support assembly 200. Another support assembly is fastened to the panel base 9 and to the rear wall 7 and is designed as a support assembly and is therefore also referred to as rear wall support assembly 300 hereinafter.

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

The surface element 400 may be comprised of a wide variety of materials. The surface element can be formed, for example, as a glass plate or a metal plate or a wood plate and can also be formed in one or more parts.

In principle, the construction of the panel structure 1 faces DE 202008011505U 1, i.e. the concept of a lateral support is maintained, which is placed on top of the panel base and encloses each edge of the surface element in a U-shape. However, as described below, the construction is improved.

The first improvement includes the following construction specific features. According to this feature, the frame base bracket 100 and the two

support assemblies

200, 300 together form a substantially U-shaped frame enclosing each edge of the surface element 400 in a U-shape in the mounted position on the panel structure 1.

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

support assemblies

200, 300 each comprise on their side facing the surface element 400 a groove or

receiver channel

101, 201, 301 which likewise has a substantially U-shaped cross section. The corresponding edges 401, 402, 403 of the surface element 400 engage in each of the

receptacle channels

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

support assemblies

200, 300 each comprise on their side facing the surface element 400 a groove or

receptacle channel

101, 201, 301 which likewise has a substantially U-shaped cross section. However, the advantageous measure of the frame base bracket 100 also having this receiver 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 bracket 100 is arranged between the panel base 9 and the surface element 400. The frame base bracket is also centered between the two

support assemblies

200, 300, which are disposed at both ends thereof.

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

Furthermore, the panel base 9 comprises an upper contact surface 13 and two vertically projecting

edges

14, 15. This contact surface 13 also forms the main side of the upper receiver 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. The frame base bracket 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, referred to as a second catch or clip element 102. The mounting of the frame base bracket 100 can be achieved simply and quickly in this way. The frame base bracket 100 comprises a lower side 103 and two

side walls

104, 105 perpendicular thereto. One of the side walls 105 has a slot 106 which here extends vertically from bottom to top in a typical mounting position of the drawer. The preferred function of this 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, lies completely above these

edges

14, 15. In this case,

walls

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

edges

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

The panel base 9 can be designed as a multi-walled structure and can be formed hollow below the receptacle channel 11, so that in particular mechanical parts can be received therein, including connection fittings and/or

elements

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

Since the frame base carrier 100 itself comprises the receptacle channel 101, its walls-side walls 104, 105-may also be designed uniformly, so that the edges of the surface element 400 are instead received in the receptacle channel 101. It is therefore advantageous that the surface element 400 is not inserted directly into the receiver channel 11, since it may comprise projections etc. inside the receiver channel and also, for example, the mentioned mounting element 12. Furthermore, since the frame base bracket 100 preferably forms a visible frame section or frame bracket for the surface element, the favourable appearance of the side panel structure thus results in this part of the panel structure 1 (see fig. 2).

The frame base bracket 100 preferably extends across the entire length between the

support assemblies

200, 300 in the main extension direction X of the panel structure 1. As the frame base carrier 100 receives and holds the lower edge of the surface element 400, said surface element is stabilized. In particular, the frame base bracket secures the surface element against deflection in the Y-direction in a simple manner.

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. Further, the panel base 9 is preferably connected to the bottom panel 8 directly or indirectly (not shown) through a fitting.

One of the

support assemblies

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

support assemblies

200, 300 each comprise a

receptacle 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. The front panel support assembly 200 is in its functional extension 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 of similar angle and a vertical corner leg 203 perpendicular thereto. The main extension directions thereof are the Y-direction and the Z-direction in the preferred mounting position shown in the figures. Preferably, the rear wall support assembly may be constructed correspondingly in the same manner.

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

support assembly

200, 300 is suitable because, in particular but not exclusively, the surface element also excellently supports at the lower edge the use on a panel structure whose panel base is composed of an inner and an outer shell, preferably made of steel sheet, which together form a substantially rectangular body in cross-section. One of the shells, the outer shell, is hidden in each of fig. 10 and 11.

Thus, what can be regarded as an improvement of the above-mentioned features or also as another advantageous feature of the independent invention rests in the implemented angular shape of the support component 200 and/or 300. This feature also facilitates particular use for narrow panel structures due to excellent dissipation of loads and the simple manner of arranging the

support assemblies

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 receiver channel 11 of the panel base 9. For this purpose, a screw 204 (see also fig. 8) can be used as fastening means, for example in particular a screw with self-tapping threads. However, alternatively or optionally, corresponding fastening members may also be formed on the panel base 9 and on the horizontal corner legs 202, e.g. catch members.

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

On its side facing the surface element 400, the front panel support assembly vertically comprises a receiver channel 201 for the vertical edge of the surface element 401. Furthermore, on the side facing away from the receiving channel 201 of the front panel 6, the front panel support assembly is fastened directly or via a fitting 205 to the front panel 6.

In this way, the front panel support assembly performs 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. Which in this way protects the surface element 400 from loads and damage.

The front panel support assembly 200 preferably includes a plurality of components for this purpose. The multipart construction makes it possible to optimally adjust it according to its various functionalities and to mount it in a simple manner.

The components of the front panel support assembly 200 preferably include fastening and support corners 206 (fig. 7 to 13) and vertical frame brackets 207 (fig. 6 to 13) designed as first cover plates for fastening and supporting the corners 206 and cover elements 208 (fig. 13) provided as outer cover plates. 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 support corner 206 may preferably consist of metal, see e.g. fig. 6a and 7, in particular the fastening and support corner 206 is formed as a stamped/bent part from a plate, preferably a steel plate. In contrast, referring to, for example, fig. 6b and 7, the vertical frame bracket 207 may also be comprised 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 comprise completely or at least in sections an L-shaped cross section, which here or preferably in each case has a

continuous base wall

209a, 210a and preferably here a

discontinuous corner wall

209b, 210 b. This L-shape ensures the required stability on the support element in a simple manner.

The horizontal leg 209 of the fastening and support corner 206 here alone forms the entire horizontal corner leg 202 of the front panel support assembly 200. In this case, the horizontal corner wall 209a of the fastening and supporting corner 206 is here inserted into the receptacle 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 screws 204, in particular using self-tapping screws 204, which are screwed into the upper side or contact surface 13 of the panel base 9. This screw is stable and tight. Alternatively, this fastening may be performed by other means and/or in another way, for example by riveting, welding or brazing. The horizontal leg 209 of the fastening and support corner 204 may itself advantageously in this case have a channel, window or groove through which elements of the panel base, such as mounting members, are thus extendable, such as those mounting members on which the frame base bracket 100 is fixed.

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

edges

14, 15 or the inside on the side wall of the receiver 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 on the upper side of the panel base 9 in the receiver channel 11, 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 a receiver channel 201 (fig. 6, 7) for the corresponding vertical edge of the surface element 400 (fig. 2) facing the surface element 400.

The cover vertical frame bracket 207 may be comprised of plastic. In this way, the covering vertical frame brackets may be optimally adapted to the task of accommodating the edges of the surface element 400. In this connection it is also advantageous that the surface element 400 is inserted into the receiving channel 201 of this plastic part to retain the material and to be protected from loads and/or damage, such as scratches, and not on metal brackets 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 wide variety of fastening members. Fixing by means of screws is preferred. However, it is also conceivable to alternatively or alternatively fasten using corresponding bayonet slots and/or clamping

members

211, 212, since this can be implemented simply and quickly. It is also possible to provide a kind of pre-mounting using corresponding snap-in slots and/or clamping

members

211, 212 and additionally provide screws 213 to fasten 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 the vertical legs 210 of the fastening and support corners 206, up to in the front panel 6 or in the fittings 205 of the front panel fasteners. The fitting 205 may comprise, for example, a plate 216 screwed onto the vertical leg 210 and preferably a pin 217, in particular a pin, which can be spread out to clamp in a bore of the front panel 6 or to connect an adapter member that functions 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 between the vertical frame bracket 207 and the front panel 6 in a free space 222 which remains towards the front panel when the vertical frame bracket 207 is attached (see also fig. 12) due to the protrusion 221 on this bracket.

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. The vertical frame bracket must well and reliably connect the front panel support assembly 200 and the front panel 6 to each other.

Near the upper end of the vertical frame bracket 207, it may extend slightly above the vertical height of the surface element, which the surface element 400 adopts in the mounted state (fig. 8b, 8 c). In this way, it is possible to provide the fixing elements 218, which vertically fasten the surface elements 400, on the vertical frame brackets 7 themselves. The fixing element 218 may be formed as a plate or pin, in particular as a metal sheet or plastic plate, and may be inserted into a corresponding recess, in particular a slot 219, of the vertical frame bracket 207 above the surface element and fastened there using a cover element 208 (see e.g. fig. 8a, 8b, 8c and 13 and e.g. fig. 2 for the cover element 208).

The components and mounting of the preferred back wall support assembly 300 are 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 to be attached or is to 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 variant, the rear wall support assembly 300 may be constructed substantially or as the front panel support assembly 200 and may be fastened in a manner similar to a rear wall, such as a wood rear wall (not shown here). In this regard, the above description should also be read in its entirety in light of this variation of the rear wall support assembly 300, wherein the phrase "front panel" should be replaced by "rear wall".

In the construction illustrated in the figures, the rear wall support assembly 300 is constructed as a large component as the front panel support assembly 200. However, it is fastened to the rear wall 7, which is a sheet metal rear wall according to the figures, in a different manner.

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

According to an advantageous exemplary embodiment illustrated in the figures, the rear wall support assembly 300 comprises a first lower horizontal corner leg 302 and a vertical corner leg 303 perpendicular thereto, to which embodiment the invention is not limited. The main directions of extension 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. Where the horizontal corner legs 302 are placed into the receiver channels 11 of the panel base 9 and secured therein. For this purpose, fastening means, such as screws 304 (as shown in fig. 13), may be used, such as screws with self-tapping threads and/or corresponding fastening means, such as catch means, on the panel base 9 and the horizontal angled legs 302.

In addition, the rear wall support assembly 300 includes a second corner leg, which is a preferred typical mounting location in the vertical corner leg 303. On its side facing the surface element 400, the front panel support assembly vertically comprises a receiver channel 301 for the vertical edge of the surface element 401. Furthermore, on the side of the receiver channel 301 facing away from the rear wall 7, the rear wall support assembly is fastened to the rear wall 7 directly or via a fitting 305.

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.

The rear wall support assembly 300 preferably includes a plurality of components for this purpose. The multipart construction makes it possible to optimally adjust it according to its various functionalities and to mount it in a simple manner.

These components preferably include fastening and support angles 306 (fig. 14 to 18), vertical frame brackets 307 (fig. 14 to 18) formed as covers for fastening and supporting the angles 306, and cover elements 308 (fig. 17) covering this arrangement.

The fastening and support corners 306 may preferably consist of metal, see e.g. fig. 6a and 7, in particular they are formed as stamped/bent parts from a plate, preferably a steel plate. The vertical frame bracket 307 may, by comparison, preferably be comprised of plastic, see, e.g., fig. 14 b.

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 completely or at least in sections comprise an L-shaped cross section, which here or preferably in each case has a

continuous base wall

309a, 310a and preferably here a

discontinuous corner wall

309b, 310 b. This L-shape is used to enhance stability and for material savings relative to the U-shape. Moreover, a narrow structure is again achieved.

The rear wall support assembly 300 here separately forms the horizontal leg 309 of the fastening and support corner 306 over the horizontal corner leg 302. In this condition, the horizontal corner wall 309a of the fastening and supporting leg 306 is inserted into the receiver channel 11 of the panel base 9 and fastened there on its contact surface 13. This fastening can be performed, for example, using the above-mentioned screws (similar to the screws 204, not shown here), in particular using self-tapping screws, which are screwed into the upper side or contact surface 13 of the panel base 9. This screw is stable and tight. Alternatively, this fastening may be performed by other means and/or in another way, for example by riveting, welding or brazing. The horizontal legs 309 of the fastening and support corners 304 may themselves advantageously in this case have a channel, window or groove through which elements of the panel base, such as mounting members, for example, those on which the frame base bracket 100 is fixed, may extend.

The corner wall 309 of the horizontal leg 309 laterally abuts, or is inserted into the slot 106 of the side wall 105 of the frame base bracket 100, on the side of one of the

sides

14, 15 or the side wall of the receiver channel 11 of the panel base 9, which further stabilizes the entire panel attachment (not shown in detail here, similar to the front panel corner assembly).

In a state where the fastening and supporting corner 306 is mounted on the upper side of the panel base 9 in the receiver channel 11, 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 bracket 307 is mounted on the vertical leg 310. This includes a receiver channel 301 (fig. 14) for a corresponding vertical edge of the surface element 400 (fig. 2) facing the surface element 400.

The vertical frame bracket 307 may be comprised of plastic. In this way, the vertical frame bracket may be optimally adapted to the task of accommodating the edges of the surface element 400. In this connection, it is also advantageous that the surface element 400 is inserted into the receiving channel 201 of this plastic part to retain the material and protect it from loads and/or damage, such as scratches, and not on metal brackets or the like.

The vertical frame bracket 307 may be fastened to the vertical leg 309 of the fastening and support corner using a wide variety of fastening members. For example, fixing by means of screws is preferred.

However, fastening using corresponding bayonet slots and/or clamping

members

311, 312 is preferred, as this can be performed simply and quickly.

Provision may also be made for a kind of pre-mounting using corresponding bayonet slots and/or clamping

members

311, 312 to be provided and additionally for stabilization of the rear wall support assembly (not shown here) using screws, such as screws 213, for fastening on the rear wall 7.

A wide variety of fastening means may be provided to secure or fasten the back wall 7 to the back wall support assembly 300.

According to fig. 14 to 17, provision is made for one or

more fastening members

321, 322 to be used for this purpose on the rear wall support assembly 300. According to the illustrated exemplary embodiment, the fastening means may have

hooks

323, 324 which are formed on the side of the vertical frame bracket 307 facing the rear wall 7 and which also penetrate the recess of the fastening and support corner 306 and engage in and lock in the

windows

18, 19 of the rear wall 7 (fig. 15a, 16). This type of installation can be made simply and quickly.

As can be seen, the

projections

325, 326 are formed between catches 423, 324 on the side of the vertical frame bracket 307 facing the rear wall 7, which catches also penetrate the recess 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, these

projections

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

projections

325, 326 is carried out using screws 20 (see also fig. 18). This type of installation can also be carried out simply and quickly. In this way, the

fastening members

321, 322 of the rear wall support assembly 300 can be used in a simple manner on the one hand to fasten to the rear wall 7 with a window, in particular made of sheet metal (using a hook), or to fasten to a rear wall, in particular made of wood (in particular using a screw).

Near the upper end of the vertical frame bracket 307, it may also extend slightly above the vertical height of the surface element, which the surface element 400 adopts in the mounted state (fig. 8b, 8 c). In this way, it is possible to also provide fixing elements, such as the fixing elements 218, on the vertical frame brackets, which vertically fasten the surface elements 400. The fixation element may likewise be formed as a plate or pin and may be inserted into at least one corresponding groove, in particular a slot 319 (fig. 16), of the vertical frame carrier above the surface element 400.

After mounting the frame base brackets 100, the support assemblies and/or here the fastening and support corners 206 and the vertical frame brackets 207 and the surface elements 400 on the panel base 9, the

cover elements

208, 308 are preferably placed on the corresponding

vertical frame brackets

207, 307 and the respective fastening and support corners 206, 306 (see e.g. fig. 13), respectively, such as the

cover elements

208, 308, which are U-shaped in side view and can be placed on these elements in a clamping and/or latching manner and hide these elements completely or partially. In this way, a favorable appearance and good protection of the elements located underneath can be achieved by means of this cover element. The

cover elements

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

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