Description

Technical Field

[0001] The present invention relates to a cross plate in the form of a container side wall, in particular a drawer side wall, having at least one back wall holder and / or at least one front wall holder, and a cross plate hat for accommodating at least one back wall holder and / or at least one front wall holder, preferably an integrally bent sheet metal profile, wherein at least one back wall holder and / or at least one front wall holder is at least partially arranged inside the sheet metal profile. The present invention further relates to an assembly comprising at least one cabinet rail with a side web for connecting at least one cabinet rail to a furniture cabinet, at least one, in particular cuboid-shaped, drawer rail with another side web oriented substantially parallel to the side web in the use state of the assembly, and at least one such cross plate. The present invention further relates to a furniture, in particular a drawer, comprising at least one furniture cabinet and at least one such cross plate. The present invention further relates to a method for manufacturing such a cross plate.

[0002] Such a cross plate is already known from the prior art, in which the back wall holder is screwed to the sheet metal profile together with the container rail.

[0003] The drawbacks in the prior art are that the screw connection part of the back wall holder requires additional component parts and an increase in assembly costs is inevitable. For example, when the screw connection part is not properly fixed, undesired force transmission may occur between the back wall holder and the cross plate, and as a result, the service life of the cross plate may be shortened. Furthermore, it is necessary to perforate the thin metal plate part, and based on the tolerance, there is a risk of stress generation inside the cross plate. Moreover, high precision is required for the perforation in the thin metal plate part; otherwise, the appearance of the cross plate will be impaired. Additionally, the screw connection part has a risk of colliding with other component parts of the cross plate and requires a structural space inside the cross plate. However, a firm connection between the back wall holder and the cross plate is essential for the use of the cross plate.

[0004] Therefore, the objective technical problem of the present invention is that the drawbacks of the prior art are at least partially eliminated. In particular, it is outstanding due to a reduced number of component parts and a compact cross plate, and / or an effective manufacturing process of a particularly firm connection between the back wall holder and / or the front wall holder and the thin metal plate part. An improved cross plate, assembly, furniture, and a method for manufacturing such a cross plate are provided as compared with the prior art.

[0005] This problem is solved by the features of claim 1.

[0006] Therefore, according to the present invention, it is specified that the thin metal profile is burr-connected (verhalst) to at least one front wall holder and / or at least one back wall holder at at least one connection point by means of at least one burring connection (Verhalsung).

[0007] For the first time, this makes it possible to dispense with screw connections, rivet connections, welding connections, or nail connections, which are usually used in the prior art.

[0008] At least one burring joint can generate a force joint in the direction of at least one burring joint opening of generally at least one back wall holder or at least one front wall holder, and / or can generate a form joint in a direction orthogonal to the burring joint opening.

[0009] At least one burring joint has proven to be a particularly good joint form for the cross plate. In particular, in the case of a sheet metal profile made of metal and a front wall holder and / or a back wall holder made of plastic, it is possible to ensure a reliable relative positioning inside the sheet metal profile without the need for special joining means or mounting means.

[0010] Generally, in at least one burring joint, the material of the sheet metal profile is plastically deformed and crimped onto the opening of at least one front wall holder and / or at least one back wall holder, particularly on the peripheral surface of the opening, by a punch or the like. The sheet metal profile is generally perforated by a punch, but this is not necessarily required.

[0011] In addition, a positive characteristic that the container rail is not required is obtained in order to enhance the sufficient stability of the cross plate and to ensure the mounting to the drawer rail.

[0012] Furthermore, since the burring joint generally does not protrude from the sheet metal profile, a flat plane can be realized on the lower surface of the sheet metal profile, and / or since the burring joint can be arranged inside the profiled part on the side surface of the sheet metal profile, a flat plane that can be covered by the container bottom can be generated.

[0013] The specialized term "crossbar hat" is designed to define a bent sheet metal profile for forming the container side wall. The bent state must be designed broadly to include also the sheet metal parts that are separated from the container rail and joined to each other in a material-bonded manner or via fixing means. Particularly preferably, the sheet metal profile is partially open downward in the use state and / or is closed downward by at least one front wall holder and / or at least one back wall holder.

[0014] As described at the beginning, patent protection is also required for an assembly consisting of at least one cabinet rail with a side web for attaching at least one cabinet rail to a furniture cabinet, at least one, in particular cuboid-shaped, drawer rail with another side web oriented substantially parallel to the side web in the use state of the assembly, and at least one such crossbar, wherein at least one crossbar is supported so as to be movable relative to at least one cabinet rail via at least one drawer rail.

[0015] Generally, an intermediate rail for the full extension of the container may be provided between at least one drawer rail and at least one cabinet rail, but this is generally not necessarily required.

[0016] The use state of the assembly may be defined by the position of the assembly in the furniture cabinet. In the use state, the assembly is prepared such that a container, such as a drawer, can be attached to the assembly to form a container without another assembly step (such as the assembly of the container rail). Thus, the vertical direction from above defines the degree of freedom that is perpendicular to the longitudinal extension direction of at least one crossbar in the direction of gravity onto the placement surface of at least one drawer rail for the container bottom.

[0017] In the assembly, force transmission between at least one drawer rail and at least one cross member and / or within at least one cross member is particularly advantageous. In the prior art, when a load is applied to the assembly, the force transmission is effected via container rails arranged on the drawer rail and the cross member for connection (with a container bottom arranged on this container rail), thereby resulting in an unstable indirect joint. In the assembly, by omitting the container rail, an assembly with increased strength / stability can be provided. This is because the flow of force between at least one drawer rail and at least one cross member (and within at least one cross member) is particularly promoted, and deformations such as bulging, buckling and similar forms (in particular due to direct connection with the container bottom in thin metal profiles) are particularly prevented.

[0018] The manufacture and assembly of the container rail and the use of mounting means such as screws for the cross member can be omitted. At least one front wall holder and / or at least one rear wall holder preferably have mounting means and / or openings for mounting means for the container front and / or the container rear wall, and the mounting means can be provided, for example, in the form of a clamping device, particularly preferably for a wooden plate.

[0019] As stated at the beginning, patent protection is also required for furniture, in particular for drawers, comprising at least one furniture cabinet and at least one such cross member, preferably at least one such assembly.

[0020] By the concept of container bottom, container rear wall, container front and the like, in the following, the component parts of the drawer, which preferably form furniture together with the furniture cabinet as a container, are defined.

[0021] As described at the beginning, patent protection is for a method of manufacturing such a crossbar, which is a method step to be carried out in the following, especially in a chronological order, that is, preparing a thin metal sheet profile and at least one front wall holder and / or at least one back wall holder, and a method step of pushing at least one front wall holder and / or at least one back wall holder and optionally at least one stabilizing element into the thin metal sheet profile of the crossbar (1), and a method step of burring and connecting the thin metal sheet profile to at least one front wall holder and / or at least one back wall holder by at least one burring connection at at least one connection point is also required for the method.

[0022] Conventionally, the crossbar is connected to the container rail and / or the front wall holder or the back wall holder by fixing means such as welding and / or rivets, screws or the like. By means of at least one burring connection, additional component parts are not required, the service life of the crossbar can be extended, the preconditions for a stable crossbar can be obtained, and the assembly cost and the manufacturing cost can be reduced.

[0023] The features of the claims of the device are also applicable to the claims of the method, and conversely, it is also possible to apply the features of the claims of the method to the claims of the device. Advantageous embodiments of the present invention are defined in the dependent claims.

[0024] Preferably, the thin metal sheet profile is burring-connected to at least one front wall holder and / or at least one back wall holder by burring connections at a plurality of connection points.

[0025] By increasing the number of burring connections, a reliable connection can be guaranteed even when a large load is applied to the crossbar.

[0026] At least one burring joint is preferably, in the state of use of the cross plate, on the side surface of the sheet metal profile, facing the drawer rail and / or the container bottom, as a component (having two side planes which are oriented substantially parallel to each other and / or spaced apart from each other by the material thickness) and / or is preferably arranged on the lower surface adjacent to the side surface of the sheet metal profile, when viewed in the state of use of the cross plate, and it has been proven to be suitable.

[0027] When at least one burring joint is arranged only on one side of the cross plate, the appearance of the cross plate is improved. When at least one burring joint is provided on two sides of the cross plate, a particularly firm joint with the sheet metal profile can be obtained and / or the precondition for obtaining a defined relative positioning of at least one front wall holder / back wall holder in the sheet metal profile in three bidirectional spatial directions is obtained.

[0028] According to an advantageous embodiment of the invention, at least one front wall holder and / or at least one back wall holder is substantially formed of plastic, at least one burring joint is located between the plastic and the metal of the sheet metal profile, and preferably, it has been specified that at least one front wall holder and / or at least one back wall holder has at least one connecting means, particularly preferably made of metal, for the container front and / or the container back wall.

[0029] At least one connecting means may be in the form of, for example, a furniture fitting, a screw connection or the like.

[0030] It has been proven to be advantageous that at least one burring joint has a substantially circular cross-section and / or at least one burring joint extends completely beyond the material thickness of the sheet metal profile and / or at least one burring joint is formed in contact with the material of at least one front wall holder and / or at least one back wall holder by the material of the sheet metal profile.

[0031] This enables the generation of a particularly firm joint between the sheet metal profile and at least one front wall holder and / or at least one rear wall holder, and the metal material of the sheet metal profile is crimped to the plastic-like material of the at least one front wall holder and / or at least one rear wall holder.

[0032] In an advantageous variant, at least one burring joint extends at least partially into at least one burring joint opening of the at least one front wall holder and / or at least one rear wall holder. Preferably, the depth of the at least one burring joint is specified to be 5% - 80%, particularly preferably 10% - 50%, and even more particularly preferably 20% - 30% of the burring joint opening depth.

[0033] The bonding strength to the sheet metal profile can be adjusted by the extent of the at least one burring joint within the at least one front wall holder and / or at least one rear wall holder. The burring joint opening may be in the form of a hole, for example. Generally, the burring joint can also be formed, for example, by a core during the injection molding process.

[0034] Particularly preferably, the sheet metal profile has, on the side of the sheet metal profile, a grooved profiling, preferably having a substantially square cross-section, which is formed to receive the container bottom.

[0035] The profiling can be incorporated into the sheet metal profile, for example, in the form of a bend. The profiling can directly connect the container bottom to at least one crossbar, and since the profiling can form a seating portion for the container bottom, in particular, an indirect connection between the crossbar and the container bottom via a container rail is not required.

[0036] In one embodiment of the present invention, the deformed part is provided with at least one mounting means for coupling and / or fixing the container bottom to the metal sheet material, particularly preferably with two claws, preferably in the form of at least one reverse barb. Preferably, at least one mounting means is fixedly coupled to the metal sheet material by material bonding, and / or is punched out from the deformed part, and / or enters laterally into the deformed part.

[0037] At least one mounting means can prevent the undesired dissociation of the container bottom arranged on the transverse plate and, in some cases, the container back wall, so that the reliable positioning of the container bottom on the transverse plate can be directly ensured.

[0038] According to a preferred embodiment of the present invention, at least one front wall holder and / or at least one back wall holder is formed in the form of an angle, preferably for being pushed into the metal sheet material through a recess corresponding to the deformed part of the metal sheet material, which may be provided, of at least one front wall holder and / or at least one back wall holder.

[0039] The angle may be provided in a plane having the longitudinal extension direction of at least one transverse plate and / or perpendicular to the plane of the longitudinal extension direction of at least one transverse plate as a structural component. Thereby, materials can be saved, and / or the stability of at least one transverse plate can be enhanced, and / or the stability of the container provided with the assembly can be enhanced.

[0040] Preferably, at least one front wall holder and / or at least one back wall holder has at least one coupling means such as a screw and / or at least one opening for arranging at least one coupling means such as a screw.

[0041] At least one stabilizing element is provided, and the at least one stabilizing element is preferably disposed in the middle and / or completely, at least partially inside the sheet metal profile, in the longitudinal extension direction of the cross plate, in order to increase the rigidity and / or strength of the cross plate. Preferably, it is specified that the at least one stabilizing element can be pushed into the sheet metal profile through a recess corresponding to a deformed portion of the sheet metal profile in which the at least one stabilizing element is optionally provided, and this has proven to be suitable.

[0042] The shape reliability of the cross plate can be enhanced by at least one stabilizing element, especially in the case of a long cross plate, even when a load is applied, and undesired deformation of the cross plate can be reduced. The recess facilitates the assembly of the at least one stabilizing element and promotes proper positioning relative to the at least one cross plate.

[0043] More preferably, it is specified that the width of the sheet metal profile is 3 mm to 10 mm, preferably 4 mm to 6 mm.

[0044] According to the present invention, the lateral extension length of the sheet metal profile can be reduced compared to a cross plate provided with container rails. This is because special connecting means such as container rails and screw connections can be omitted. Thereby, a particularly compact arrangement form can be obtained. For example, the storage space in a container having such an arrangement form can be made larger, or a thinner container can be obtained when the storage space is the same.

[0045] In another embodiment, it is specified that the at least one front wall holder and / or the sheet metal profile has at least one connecting device for direct connection, preferably without container rails, to a drawer rail.

[0046] If at least one connecting device is arranged directly on the front wall holder or the sheet metal profile, the indirect connection to at least one drawer rail via the container rail can be omitted. Thereby, the force transmission between at least one cross plate and at least one drawer rail is advantageously effected.

[0047] According to an advantageous configuration of the invention, it has been determined that at least one cross plate, preferably the side surface of the sheet metal profile, is at least partially directly arranged between a side web and another side web in a fixed state to at least one drawer rail.

[0048] Thereby, the container rail which functions as a connecting member between at least one cross plate and the drawer rail can be completely omitted. At least one cross plate, in particular the side surface of the sheet metal profile, also serves for the direct connection of the container bottom and for the direct connection to the drawer rail (for example via at least one front fitting) by the relative positioning between at least one cabinet rail and at least one drawer rail.

[0049] For manufacturing - technical and assembly - technical improvements such as material savings, component reduction, reduced assembly costs, cost savings, etc., there is further added the positive characteristic that at least one drawer rail is not covered upwards in the use state by the container rail, whereby at least one drawer rail can serve as a mounting part for the container bottom.

[0050] The side surface as an integrated component of the sheet metal profile facing at least one drawer rail is generally a side surface arranged substantially parallel to the side surface facing at least one cabinet rail (this side surface may generally have, for example, a bent portion).

[0051] The text can be directly interpreted synonymously with the concept, that is, there is no container rail arranged on at least one of the sheet metal profiles of the crossbars. That is, starting from the web and / or another web, in the direction orthogonal to the web and / or another web, instead of the container rail, a sheet metal profile is arranged.

[0052] The side surface as an integrated component of the sheet metal profile facing at least one drawer rail is generally arranged substantially parallel to the side surface facing at least one cabinet rail (this side surface may generally have, for example, a bent part).

[0053] According to an advantageous configuration of the present invention, at least one drawer rail is a placement surface oriented substantially orthogonally to another side web, preferably adjacent to another side web, and having a placement surface for directly supporting the container bottom in the use state of the assembly. Preferably, it is specified that the placement surface is freely accessible from above in the vertical direction, particularly preferably at least partially and / or in the region of the contact area for the container bottom in the use state of the assembly.

[0054] In the prior art, the container bottom is placed on the container rail. By the placement surface of the drawer rail, on the one hand, the container rail can be omitted, and particularly stable support of the container bottom on at least one drawer rail can be achieved.

[0055] Advantageously, it is specified that exactly one sheet metal profile is provided for the direct connection with the drawer rail and / or the container bottom.

[0056] Preferably, this exactly one sheet metal profile is formed exclusively by crossbar hats, particularly without a container rail.

[0057] It has proven to be advantageous if at least one crossbar is directly connected to at least one drawer rail by contact, preferably without a container rail, by means of a thin metal profile and / or at least one connecting device of at least one front wall holder.

[0058] If at least one connecting device is arranged directly on the front wall holder or the thin metal profile, an indirect connection to at least one drawer rail via a container rail can be omitted. This enables the force transmission between at least one crossbar and at least one drawer rail to be advantageously effected.

[0059] According to an advantageous embodiment of the invention, the assembly has at least one container bottom, which is in contact directly with the thin metal profile, preferably without a container rail, and / or via a groove-shaped profiling for receiving at least one container bottom on the side of the thin metal profile, and at this time it is preferably specified that at least one container bottom is fixed to the thin metal profile by means of at least one mounting means.

[0060] In the prior art, the container bottom is placed on the container rail in a narrow contact area and is arranged without contacting the crossbar. By having at least one container bottom in direct contact with at least one crossbar, the container rail can be omitted, and furthermore, a simplified, reliable and / or stable connection of at least one container bottom can be ensured.

[0061] It has proven to be advantageous if at least one container bottom is arranged substantially flush with at least one drawer rail, and preferably it is specified that at least one container bottom is placed planar on at least one drawer rail.

[0062] If at least one container bottom is placed planar on at least one extraction rail, the at least one container bottom can be resistant to being undesirably bent by a placement portion formed via the at least one extraction rail for the at least one container bottom. Generally, the at least one container bottom may be arranged with a play with respect to the at least one extraction rail, for example, contact only occurs when a load is applied to the assembly.

[0063] In an advantageous variant, the assembly includes at least one container back wall arranged in at least one back wall holder.

[0064] Preferably, it is specified that when a load, preferably a vertical load and / or a lateral load, is applied to the assembly in the use state of the assembly, the force transmission can be directly transmitted, preferably without a container rail, between at least one cross plate, preferably a sheet metal profile and / or at least one front wall holder and / or at least one back wall holder, and at least one extraction rail.

[0065] Since the container rail can be omitted, the required time for the flow of force inside at least one cross plate and / or between at least one cross plate and at least one extraction rail when a load is applied to the assembly can be extended.

[0066] Particularly preferably, in the method step of preparation, at least one burring connection opening is formed in at least one front wall holder and / or at least one back wall holder, at least one burring connection is formed between the plastic of at least one front wall holder and / or at least one back wall holder and the metal of the sheet metal profile, preferably with a substantially circular cross section, and at least one burring connection is extended at least partially within at least one burring connection opening of at least one front wall holder and / or at least one back wall holder.

[0067] Preferably, at least one burring joint is preferably processed automatically by at least one punch or pin, and preferably, a sheet metal profile is joined by burring joints at a plurality of joining points, particularly preferably, by burring joints arranged on the side surface of the sheet metal profile and / or on the lower surface of the sheet metal profile as seen in the use state of the cross plate, to at least one front wall holder and / or at least one rear wall holder by burring.

[0068] By doing so, the manufacturing cost for forming the cross plate can be reduced, so that a particularly effective manufacturing process can be carried out.

[0069] Preferably, the punch preferably has a conical tip at its free end and / or has a diameter which is substantially the value obtained by subtracting twice the material thickness of the sheet metal profile from the width of the burring joint opening.

[0070] According to a preferred embodiment, it is specified that the material of the sheet metal profile is crimped to at least one burring joint opening, thereby forming a force-coupling joint along at least one burring joint opening and / or a form-coupling joint orthogonal to at least one burring joint opening.

[0071] By doing so, a particularly reliable and stable joint can be generated between the sheet metal profile and at least one front wall holder and / or rear wall holder.

[0072] Next, further details and advantages of the present invention will be described in detail with reference to the embodiments shown in the drawings by the description of the drawings.

[0074] In FIG. 1a, the horizontal plate 1 in the form of a container side wall formed as a drawer side wall is shown in an exploded view.

[0075] The horizontal plate 1 has a back wall holder 3, a front wall holder 4, and a bent integral metal thin plate profile 2 in the form of a horizontal plate hat for accommodating the back wall holder 3 and the front wall holder 4.

[0076] The metal thin plate profile 2 is provided with a groove-shaped deformed portion 9 having a substantially square cross-section 10 on the side surface 8 of the metal thin plate profile 2, and this deformed portion 9 is formed for accommodating the container bottom 7.

[0077] The deformed portion 9 is provided with mounting means 11 in the form of a reverse hook 12 having two claws 13 (the number of claws 13 is generally arbitrary) for bonding the container bottom 7 to the metal thin plate profile 2 and fixing the container bottom 7 to the metal thin plate profile 2. The mounting means 11 is bonded to the metal thin plate profile 2 in a material-bonded manner, punched out from the deformed portion 9, and enters horizontally into the deformed portion 9.

[0078] The front wall holder 4 and the rear wall holder 3 are formed in the form of an angle 17 (in a plane along the longitudinal extension direction 15 or in a plane perpendicular to the longitudinal extension direction 15) for pushing into the sheet metal profile 2 through recesses 18 corresponding to the deformed portions 9 of the sheet metal profile 2 of the front wall holder 4 and the rear wall holder 3.

[0079] Figure 1b shows the transverse plate 1 in a partially assembled state before machining the flanging joint for connecting the front wall holder 4 and the rear wall holder 3 to the sheet metal profile 2. At this time, the rear wall holder 3 and the front wall holder 4 are arranged inside the sheet metal profile 2.

[0080] Figure 2a shows that the front wall holder 4 (generally also considered for the sheet metal profile 2) has a connecting device 5 for directly connecting to the drawer rail 6 without a container rail (see Figure 10).

[0081] Figure 2b shows that the sheet metal profile 2 has already been flanging-connected by the flanging joint 20 at a number of connection points 19 to the front wall holder 4 (and possibly also to the rear wall holder 3 in some cases). The flanging joint is arranged on the side surface 8 of the sheet metal profile 2 facing the drawer rail 6 or the container bottom 7 (see Figure 5b) in the use state of the transverse plate 1.

[0082] A further flanging joint 20 is arranged on the lower surface 22 (see Figure 5b) of the sheet metal profile 2 adjacent to the side surface 8 of the sheet metal profile 2 as seen in the use state of the sheet metal profile 2.

[0083] The flanging joint 20 is automatically processed by a punch 41. At this time, the punch 41 has a conical tip at its free end, and at this free end, the material of the sheet metal profile 2 can be crimped to the material of the front wall holder 4 through the flanging joint opening 36.

[0084] The front wall holder 4 and the rear wall holder 3 are basically formed of plastic, and the burring joint 20 is located between the plastic and the metal of the metal sheet profile 2. The front wall holder 4 has coupling means 39 for the front surface 24 of the metal container.

[0085] Figure 3a shows the process step of machining the burring joint 20 at the lower surface 22 of the metal sheet profile 2 at the joint with the front surface 24 of the container.

[0086] Figure 3b shows that the metal sheet profile 2 has a width 16, and this width 16 is between 4 mm and 6 mm. The burring joint 20 is machined, whereby the crossbar 1 can be directly coupled to the drawer rail 6.

[0087] The burring joint 20 at the lower surface 22 results in a flat lower surface 22. The burring joint at the side surface 8 is arranged inside the profiling 9 and is covered by the container bottom 7 after the attachment of the container bottom 7.

[0088] Figure 4a shows that the burring joint 20 has a circular cross-section 40, that the burring joint 20 extends completely beyond the material thickness of the metal sheet profile 2, and is formed in contact with the material of the front wall holder 4 or the rear wall holder 3 by the material of the metal sheet profile 2.

[0089] The difference between Figure 4b and Figure 4a is simply that the punch 41 has already been removed from the burring joint opening 36.

[0090] The burring joint 20 extends partially into the burring joint opening 36 of the front wall holder 4 (or the rear wall holder 3).

[0091] The depth 37 of the burring joint 20 is between 10% and 50% of the burring joint opening depth 38.

[0092] Figure 5a shows an enlarged and detailed view of a part of the crossbar 1 in the region of the rear wall holder 3.

[0093] A method for manufacturing the transverse plate 1 can be exemplified as follows (without a mandatory chronological relationship): - Prepare the sheet metal profile 2, the front wall holder 4 and the rear wall holder 3, and push the front wall holder 4 and the rear wall holder 3 (optionally together with the stabilizing element 14) into the sheet metal profile 2 of the transverse plate 1, - Form at least one burring joint opening 36 in the front wall holder 4 or the rear wall holder 3, - Burr-connect the sheet metal profile 2 to the front wall holder 4 and the rear wall holder 3 by means of burring joints 20 at at least one connection point 19, form the burring joints 20 between the plastic of the front wall holder 4 and the rear wall holder 3 and the metal of the sheet metal profile 2, and extend the burring joints 20 partially within the burring joint openings 36 of the front wall holder 4 or the rear wall holder 3.

[0094] FIG. 5b shows that the burring joints 20 have a circular cross-section 40 and are each arranged in the end region of the sheet metal profile 2.

[0095] The difference between FIG. 5c and FIG. 5b is simply that the transverse plate 1 is shown from the lower surface 22.

[0096] The material of the sheet metal profile 2 is crimped to the burring joint opening 36 such that the force-locking connection is located along the burring joint opening 36 and the form-locking connection is located orthogonally to the burring joint opening.

[0097] FIG. 6a shows that the rear wall holder 3 has connection means 39 for the container rear wall 25, and the connection means 39 are in the form of clamping means that can be crimped to the container rear wall 25 and in the form of openings for screw-like fixing means. Generally, simply clamping means or openings may be provided.

[0098] The crossbar 1 is in a fully assembled state and is in a ready state to be directly coupled to the drawer rail 6 or the container bottom 7.

[0099] The sheet metal profile 2 is clinch - connected to the front wall holder 4 and the rear wall holder 3 at a number of connection points 19, and the number of connection points 19 is generally arbitrary.

[0100] The clinch joint 20 is arranged inside the profiled part 9 on the side 8 of the sheet metal profile 2, but this is not necessarily required.

[0101] Figure 6b differs from Figure 3a only in that the crossbar 1 is viewed from a different line of sight.

[0102] The clinch joint 20 is arranged on the lower surface 22 of the sheet metal profile 2 in the usage state 21 of the crossbar 1. Generally, it is possible to provide the clinch joint only on the side 8 or the lower surface 22.

[0103] Figure 7a shows a container 29 in the form of a drawer 31 for furniture, comprising a furniture cabinet (not shown in the drawing for clarity) and at least one assembly consisting of the crossbar 1, the drawer rail 6, and the cabinet rail 23, and the drawer rail 6 is covered by the container bottom 7.

[0104] The container bottom 7 is in contact with the side 8 of the sheet metal profile 2 directly and without a container rail, via a groove - shaped profiled part 9 for accommodating the container bottom 7. The container bottom 7 is fixed to the sheet metal profile 2 via the mounting means 11, and exactly one sheet metal profile 2 is provided for the direct connection to the drawer rail 6 and the container bottom 7.

[0105] The clinch joint 20 supports the assembly process of the container 29 by its structural dimensions.

[0106] The container front 24 is schematically shown by a dashed line.

[0107] The container bottom 7 is arranged flush with the drawer rail 6, and the container bottom 7 is placed flat on the drawer rail 6.

[0108] The difference between Fig. 7b and Fig. 4a is simply that they are viewed from different line-of-sight angles. In the detailed view showing a partial enlargement, it can be seen that the container back wall 25 is arranged in the back wall holder 3.

[0109] Figs. 8a and 8b show the crossbar 1 formed in the form of the container side wall as the drawer side wall, and are shown in a disassembled state for direct attachment to the container bottom 7 and the drawer rail 6 (see Fig. 10).

[0110] In Fig. 8a, the crossbar has a crossbar hat (formed from an integral bent sheet metal profile 2) for accommodating the back wall holder 3 and the front wall holder 4. The front wall holder 4 is configured for connection to the container front face 24, and the back wall holder 3 is configured for connection to the container back wall 25.

[0111] The front wall holder 4 of the crossbar 1 has a connecting device 5 for direct connection with the drawer rail 6 without a container rail. Generally, the connecting device 5 can alternatively or additionally be arranged on the sheet metal profile 2, so that an indirect connection between the drawer rail 6 and the crossbar 1 is prevented via a container rail arranged between the crossbar 1 and the drawer rail 6.

[0112] The crossbar 1 has a stabilizing element 14, which can be partially arranged inside the sheet metal profile 2 in the middle in the longitudinal extension direction 15 of the crossbar 1 to increase the rigidity and strength of the crossbar 1. Generally, it is also possible to omit the stabilizing element 14, especially when the longitudinal extension direction 15 of the crossbar 1 is short.

[0113] The sheet metal profile 2 is provided on the side surface 8 of the sheet metal profile 2 with a groove-shaped profiling 9 having a substantially square cross-section 10, and this profiling 9 is formed for accommodating the container bottom 7 (see Fig. 7a).

[0114] The stabilizing element 14 can be pushed into the metal sheet profile 2 through a recess 18 corresponding to the deformed portion 9 of the metal sheet profile 2 of the stabilizing element 14.

[0115] Figure 8b shows a crossbar 1 without the stabilizing element 14, and such a crossbar 1 can be used, for example, for low loads or for a slight longitudinal extension direction 15.

[0116] A number of mounting means 11 are arranged in the deformed portion 9, and the number of the mounting means 11 is generally arbitrary. The mounting means 11 are in the form of reverse hooks 12, and each reverse hook 12 has two claws 13. The mounting means 11 are suitable for coupling the container bottom 7 to the metal sheet profile 2 and for fixing the container bottom 7 to the metal sheet profile 2. The reverse hooks 12 may be formed in other forms.

[0117] The mounting means 11 are bonded to the metal sheet profile 2 in a material-bonded manner, are punched out from the deformed portion 9, and enter laterally into the deformed portion 9.

[0118] The front wall holder 4 and the rear wall holder 3 are formed of plastic, and the mounting means for the container rear wall 25 or the container front face 24 are formed of metal.

[0119] The front wall holder 4 and the rear wall holder 3 are in the form of an angle 17 (in two spatial directions that are perpendicular to each other in some cases), and are formed for pushing into the metal sheet profile 2 through a recess 18 corresponding to the deformed portion 9 of the metal sheet profile 2 of the front wall holder 4 and the rear wall holder 3.

[0120] Figure 9a shows the crossbar 1 in an assembly method, and the front wall holder 4 has already been pushed into the metal sheet profile 2.

[0121] FIG. 9b differs from FIG. 9a only in that the back wall holder 3 is also pushed into the sheet metal profile 2 of the cross plate 1 during the assembly process step.

[0122] The width 16 of the sheet metal profile 2 is 4 mm to 6 mm.

[0123] FIG. 10 shows an assembly consisting of a cabinet rail 23 with a side web 28 for coupling the cabinet rail 23 to a furniture cabinet, a rectangular drawer rail 6 with another side web 30 oriented parallel to the side web 28 in the use state 21 of the assembly, and at least one cross plate 1 in the form of a container side wall as a drawer side wall.

[0124] The drawer rail 6 has a mounting surface 34 that is oriented perpendicular to the other side web 30 and adjacent to the other side web 30, and the mounting surface 34 directly supports the container bottom 7 in the use state 21 of the assembly. In the use state 21 of the assembly, the mounting surface 34 is freely accessible from above in the vertical direction 35, and in particular in the region of the contact area for the container bottom 7.

[0125] By means of the connecting device 5, the cross plate 1 is directly connected to the drawer rail 6 by contact and without a container rail.

[0126] The cross plate 1 is supported so as to be movable relative to at least one cabinet rail 23 via the drawer rail 6, and here an intermediate rail 32 is provided to ensure the full extension of the drawer 31. However, the intermediate rail 32 is not generally necessarily required.

[0127] The cross plate has a front wall holder 4 for coupling the container front 24, a back wall holder 3 for coupling the container back wall 25, and a bent integral sheet metal profile 2 in the form of a cross plate hat for accommodating the back wall holder 3 and the front wall holder 4, and the front wall holder 4 is completely and the back wall holder 3 is partially arranged inside the sheet metal profile 2.

[0128] In the usage state 21 of the assembly, the side surface 8 of the sheet metal profile 2 of the cross plate 1 facing the drawer rail 6 is partially directly in a state of being fixed to the drawer rail 6 and is arranged in a direction orthogonal to the side web 28 or another side web 30 between the side web 28 and another side web 30.

[0129] In a detailed view showing a part, the connection part between the cross plate 1 and the drawer rail 6 is shown enlarged, and the connecting device 5 of the front wall holder 4 (or in some cases the sheet metal profile 2) engages into a corresponding connecting device 33 in the form of a recess or groove of the drawer rail 6.

[0130] The connecting device 5 has a stepped contour that facilitates the connection process or disconnection process between the cross plate 1 and the drawer rail 6.

[0131] The cross plate 1 is directly arranged between the side web 28 of the cabinet rail 23 for connecting the cabinet rail 23 and the container 29 and another side web 30 of the drawer rail 6 arranged parallel to the side web 28.

[0132] When a vertical load or a lateral load is applied to the assembly in the usage state 21 of the assembly, the force transmission can be directly between the cross plate 1 and the drawer rail 6 without a container rail.
