Abstract
Description
Technical Field
[0001] The invention relates to a side frame in the form of a container side wall, in particular a drawer side wall, which comprises at least one rear wall bracket and / or at least one front wall bracket and a preferably one-piece bent sheet metal profile in the form of a frame cap for accommodating at least one rear wall bracket and / or at least one front wall bracket, wherein the at least one rear wall bracket and / or the at least one front wall bracket are at least partially arranged within the sheet metal profile. In addition, the invention relates to a configuration system, which comprises: at least one body rail, which has a side strip for connecting the at least one body rail and a furniture body; at least one drawer rail, which is in particular cuboid in shape, which has another side strip oriented substantially parallel to the side strip in the use state of the configuration system; and at least one such side frame. In addition, the invention relates to a piece of furniture, in particular a drawer, which comprises at least one furniture body and at least one such side frame. In addition, the invention relates to a method for producing such a side frame. Background Art
[0002] Such side frames are already known from the prior art in which the rear wall support and the sheet metal profile are screwed together with the container rail.
[0003] The disadvantage of the prior art is that the screw connection of the rear wall support requires additional components and causes increased assembly effort, wherein, for example, in the case of improper screw connection fixing, undesirable force transmission occurs between the rear wall support and the side frame, and this undesirable force transmission may lead to a shortened service life of the side frame. In addition, holes must be drilled in the sheet metal parts, wherein, due to tolerances, there is a risk of stresses in the side frame and the drilling of the sheet metal parts requires very high precision in order not to impair the visual appearance of the side frame. In addition, the screw connection also implies the risk of collision with other components of the side frame and requires structural space in the side frame. However, in the use of the side frame, the fixed connection between the rear wall support and the side frame is of vital importance. Summary of the invention
[0004] Therefore, the objective technical task of the present invention is to provide a side frame, a configuration system, a piece of furniture and a method for manufacturing a side frame that are improved compared to the prior art, in which the disadvantages of the prior art are at least partially eliminated, and the outstanding advantages of the side frame, the configuration system, the furniture and the method are particularly efficient in the manufacturing process, reduced number of structural components, compact side frame and / or particularly strong connection between the rear wall bracket and / or the front wall bracket and the metal sheet component.
[0005] This object is achieved by the features of claim 1 .
[0006] Accordingly, it is provided according to the invention that the sheet metal profile is crimped to the at least one front wall support and / or to the at least one rear wall support at at least one connecting point by means of at least one crimp.
[0007] This makes it possible, firstly, to avoid the need for screw connections, rivets, welding or nail connections, which are usually used in the prior art.
[0008] By means of the at least one crimping portion, a force fit can be produced in the direction of the at least one crimping portion - typically along the crimping hole of the at least one rear wall bracket or the at least one front wall bracket - and / or a form fit can be produced in a direction orthogonal to this direction.
[0009] The at least one crimping portion has proven to be a particularly advantageous connection for the side frame, wherein, in particular for a sheet metal profile made of metal and a front wall support and / or a rear wall support made of plastic, a reliable relative positioning within the sheet metal profile can be ensured - without the need for special connecting or fixing devices.
[0010] Typically, for the at least one crimping, the material of the sheet metal profile is pressed by a punch or similar device via plastic deformation onto an opening, in particular the circumference of the opening, of the at least one front wall support and / or the at least one rear wall support. The sheet metal profile is typically drilled with a punch, but this is not absolutely necessary.
[0011] A further positive feature is that no container rail is required to provide adequate stability for the side frames and to ensure connection to the drawer rail.
[0012] Furthermore, the crimping portion usually does not protrude from the sheet metal profile, so that a flat surface can be produced on the underside of the sheet metal profile and / or the crimping portion can be arranged within the contour on the side of the sheet metal profile, so that a flat surface can be formed, which can be covered by the container bottom.
[0013] The technical term "frame cap" is to be interpreted as defining a curved sheet metal profile for forming a container side wall. Curved is to be interpreted broadly such that, in addition to the container rail, it also includes sheet metal parts that are connected to one another in a materially bonded manner or via fastening means. Particularly preferably, the sheet metal profile is partially open downwards in the use state and / or is closed downwards by the at least one front wall support and / or the at least one rear wall support.
[0014] As mentioned at the beginning, protection is also claimed for a configuration system comprising at least one main body rail, at least one, in particular cuboid, drawer rail and at least one such side frame, wherein the main body rail has a side strip for connecting the at least one main body rail and the furniture body, and the drawer rail has a further side strip oriented essentially parallel to the side strip in the use state of the configuration system, wherein the at least one side frame can be supported movably relative to the at least one main body rail via the at least one drawer rail.
[0015] Typically, an intermediate rail for completely pulling out the container may be provided between the at least one drawer rail and the at least one body rail, wherein the intermediate rail is generally not necessary.
[0016] The use state of the arrangement system can be defined by the position of the arrangement system on the furniture carcass, wherein the arrangement system is ready in the use state for fastening a container bottom, a container front and / or a container rear wall to the arrangement system without further assembly steps, such as assembly of container rails, to form a container, such as a drawer. Thus, "vertically from above" defines the degree of freedom of the support surface for the container bottom in the direction of gravity, which is perpendicular to the longitudinal extension of the at least one side frame and faces the at least one drawer rail.
[0017] In the arrangement, the force transmission between the at least one drawer rail and the at least one side frame and / or within the at least one side frame is particularly advantageous. In the prior art, when the arrangement is loaded, the force transmission takes place via a container rail arranged for coupling to the drawer rail and the side frame, on which the container bottom rests, thereby producing an unstable indirect connection. In the arrangement, a strength / stability-enhanced arrangement can be provided by omitting the container rail, since the force flow between the at least one drawer rail and the at least one side frame (and within the at least one side frame) is particularly advantageous and deformations, such as expansions, bending and the like, are particularly prevented (especially due to the direct coupling to the container bottom on the sheet metal profile).
[0018] The production and assembly of container rails and the use of fixing means, such as screws, for the side frames can be omitted. The at least one front wall support and / or the at least one rear wall support preferably comprise fixing means and openings for fixing means for the container front and / or container rear wall, wherein the fixing means can be present, for example, in the form of clamping devices, particularly preferably for wooden boards.
[0019] As mentioned at the outset, protection is also claimed for a piece of furniture, in particular a drawer, which has at least one furniture carcass and at least one such side frame, preferably at least one such arrangement system.
[0020] In the following the terms container bottom, container rear wall, container front etc. are preferably used to define the structural parts of the drawer which, as a container, forms a piece of furniture together with a furniture body.
[0021] As mentioned at the outset, protection is also claimed for a method for producing such a side frame, wherein the following method steps are carried out, in particular in chronological order: a sheet metal profile and at least one front wall bracket and / or at least one rear wall bracket are provided, wherein the at least one front wall bracket and / or the at least one rear wall bracket and, if necessary, at least one stabilizing element are pushed into the sheet metal profile of the side frame (1); and the sheet metal profile is crimped to the at least one front wall bracket and / or to the at least one rear wall bracket at at least one connection point by means of at least one crimping portion.
[0022] Conventionally, the side frame is connected to the container rail and / or the front wall support or the rear wall support via welding and / or fixing means, such as rivets, screws, etc. By means of the at least one crimping portion, no additional structural components are required, the service life of the side frame can be increased, a stable side frame can be produced and the assembly and manufacturing costs can be reduced.
[0023] Features of the device claim may be applied to the method claim and vice versa. Advantageous embodiments of the invention are defined in the dependent claims.
[0024] It is advantageously provided that the sheet metal profile is crimped to the at least one front wall support and / or to the at least one rear wall support at a plurality of connection points by means of crimps.
[0025] Due to the increased number of crimping points, a secure connection can be ensured despite high loads on the side frames.
[0026] It has proven to be advantageous if the at least one crimping portion is arranged on a side of the sheet metal profile that preferably faces the drawer rail and / or the container bottom when the side frame is in use (as a structural component having two side planes that are oriented essentially parallel and / or spaced apart from each other by material thickness) and / or on an underside of the sheet metal profile that is positioned when the side frame is in use, preferably adjacent to the side.
[0027] If the at least one crimping is arranged only on one side of the side frame, the aesthetic appearance of the side frame is improved. If the at least one crimping is present on both sides of the side frame, a particularly strong connection to the sheet metal profile can be produced and / or a defined relative positioning of the at least one front wall bracket / rear wall bracket on the sheet metal profile can be achieved - in three bidirectional spatial directions.
[0028] According to a preferred embodiment of the present invention, it is provided that: the at least one front wall bracket and / or the at least one rear wall bracket are basically composed of plastic, and the at least one crimping portion is between the plastic and the metal of the metal sheet profile. It is preferably provided that: the at least one front wall bracket and / or the at least one rear wall bracket include at least one connecting device for the container front and / or the container rear wall, and the connecting device is preferably made of metal.
[0029] The at least one connecting means may be present, for example, in the form of a furniture fitting, a screw connection or the like.
[0030] It has proven to be advantageous if the at least one crimping portion has a substantially circular cross-section and / or if the at least one crimping portion extends completely over the material thickness of the sheet metal profile and / or if the at least one crimping portion is formed by the material of the sheet metal profile contacting the material of the at least one front wall support and / or the at least one rear wall support.
[0031] This allows a particularly strong connection to be produced between the sheet metal profile and the at least one front wall support and / or the at least one rear wall, wherein the metal material of the sheet metal profile is pressed onto the plastic-like material of the at least one front wall support and / or the at least one rear wall support.
[0032] An advantageous variant is that the at least one crimping portion at least partially extends into at least one crimping hole of the at least one front wall bracket and / or the at least one rear wall bracket, and it is preferably provided that the depth of the at least one crimping portion is between 5% and 80% of the depth of the crimping hole, particularly preferably between 10% and 50%, and further particularly preferably between 20% and 30%.
[0033] By extending the at least one crimping portion within the at least one front wall support and / or the at least one rear wall support, the strength of the connection to the sheet metal profile can be adjusted. The crimping hole can be embodied, for example, in the form of a drilled hole. The recess can also be produced, for example, by core forming, in the course of an injection molding process.
[0034] Particularly preferably, the sheet metal profile comprises a groove-like contour on a side surface of the sheet metal profile, preferably with a substantially rectangular cross section, which is designed to accommodate a container bottom.
[0035] The profile can be introduced into the sheet metal profile, for example in the form of an angled portion. The container bottom can be connected directly to the at least one side frame via the profile, wherein the profile can form a support for the container bottom, so that in particular an indirect connection between the side frame and the container bottom via a container rail is no longer necessary.
[0036] In one embodiment of the present invention, it is provided that: the contour portion includes at least one fixing device, preferably in the form of at least one barb, particularly preferably with two serrations, for connecting the container bottom and the metal sheet profile and / or for fastening the container bottom to the metal sheet profile. It is preferably provided that: the at least one fixing device is connected to the metal sheet profile in a material-bonded manner and / or is punched out of the contour portion and / or extends laterally into the contour portion.
[0037] The at least one fixing means can prevent an undesired loosening of the container bottom arranged on the side frame—and optionally the container rear wall—so that a secure positioning of the container bottom directly on the side frame can be ensured.
[0038] According to a preferred embodiment of the present invention, it is provided that the at least one front wall bracket and / or the at least one rear wall bracket is designed in the form of an angle piece for being pushed into the metal sheet profile, preferably via a recess of the at least one front wall bracket and / or the at least one rear wall bracket corresponding to a contour portion of the metal sheet profile that may be present.
[0039] The angle piece can be provided as a structural component in a plane with the longitudinal extension of the at least one side frame and / or in a plane orthogonal to the longitudinal extension plane of the at least one side frame. This can save material and / or improve the stability of the at least one side frame and / or increase the stability of the container with the configuration system.
[0040] Preferably, the at least one front wall bracket and / or the at least one rear wall bracket comprises at least one connecting means, such as a screw, and / or at least one opening for arranging at least one connecting means, such as a screw.
[0041] It has proven to be advantageous to provide at least one stabilizing element which is preferably centered in the longitudinal extension of the side frame and / or is arranged completely or at least partially within the sheet metal profile in order to increase the rigidity and / or strength of the side frame, preferably providing that the at least one stabilizing element can be pushed into the sheet metal profile via a recess of the at least one stabilizing element which corresponds to a contour portion of the sheet metal profile which may be present.
[0042] By means of the at least one stabilizing element, the dimensional stability of the side frame can be increased under load, in particular for long side frames, and undesired deformations of the side frame can be reduced. The recess facilitates the assembly of the at least one stabilizing element and facilitates the correct positioning relative to the at least one side frame.
[0043] Furthermore, it is preferably provided that the width of the sheet metal profile is between 3 mm and 10 mm, preferably between 4 mm and 6 mm.
[0044] According to the invention, the lateral extension of the sheet metal profile can be reduced compared to side frames with container rails, since container rails and special connection means, such as screw connections, can be omitted. This makes it possible to implement a particularly compact arrangement, wherein, for example, more storage space can be created in a container with such an arrangement or a narrower container can be created with the same storage space.
[0045] In a further embodiment, it can be provided that the at least one front wall bracket and / or the sheet metal profile comprises at least one coupling device for direct coupling to a drawer rail, preferably without a container rail.
[0046] If the at least one coupling device is directly arranged on the front wall bracket or the sheet metal profile, an indirect connection with the at least one drawer rail via the container rail can be omitted. Thus, force transmission is advantageously achieved between the at least one side frame and the at least one drawer rail.
[0047] According to an advantageous embodiment of the invention, it is provided that the at least one side frame, preferably a side face of a sheet metal profile, is arranged at least partially directly between the side strip and the further side strip when fastened to the at least one drawer rail.
[0048] This makes it possible to completely dispense with a container rail, which serves as a connection element between the at least one side frame and the drawer rail. The at least one side frame, in particular a side surface of a sheet metal profile, can be used both for direct connection of the container bottom and for direct coupling to the drawer rail (e.g. via the at least one front fitting) by the relative positioning between the at least one carcass rail and the at least one drawer rail.
[0049] In addition to improvements in production and assembly technology, such as saving material, reducing components, reducing assembly effort, saving costs, etc., there is also the positive feature that the at least one drawer rail is not covered upward by the container rail in the use state, so that the at least one drawer rail can be used as a support for the container bottom.
[0050] The side facing the at least one drawer rail as an integral component of the sheet metal profile usually constitutes the side which is arranged essentially parallel to the side facing the at least one carcass rail (which side usually can have a bend, for example).
[0051] This statement can be interpreted directly synonymously in terms of, in other words, no container rail is arranged on the sheet metal profile of the at least one side frame. This means that starting from the side strip and / or the further side strip, no container rail is positioned but rather a sheet metal profile is positioned in a direction orthogonal to the side strip and / or the further side strip.
[0052] The side facing the at least one drawer rail as an integral component of the sheet metal profile usually constitutes the side which is arranged essentially parallel to the side facing the at least one carcass rail (which side usually can have a bend, for example).
[0053] According to an advantageous design of the invention, it is provided that: the at least one drawer rail comprises a support surface oriented essentially orthogonally to the other side strip, preferably adjacent to the other side strip, for directly supporting the bottom of the container when the configuration system is in use, preferably providing that: the support surface is freely accessible in the vertical direction from above, particularly preferably at least partially and / or in the area of the contact zone for the bottom of the container when the configuration system is in use.
[0054] In the prior art, the container bottom is placed on the container rail. Through the support surface of the drawer rail, on the one hand, the container rail can be omitted and the container bottom can be supported particularly stably on the at least one drawer rail.
[0055] Advantageously, provision is made for exactly one sheet metal profile to be provided for direct connection to a drawer rail and / or to a container bottom.
[0056] Preferably, the precisely one sheet metal profile is formed exclusively by the frame cap, in particular without the container rail.
[0057] It has proven to be advantageous if the at least one side frame is coupled to the at least one drawer rail directly by contact, preferably without a container rail, via at least one coupling device of the sheet metal profile and / or of the at least one front wall bracket.
[0058] If the at least one coupling device is directly arranged on the front wall bracket or the sheet metal profile, then the indirect connection via the container rail and the at least one drawer rail can be omitted. Thus, power transmission is advantageously achieved between the at least one side frame and the at least one drawer rail.
[0059] According to an advantageous embodiment of the invention, it is provided that the configuration system comprises at least one container bottom, which contacts the sheet metal profile directly, preferably without a container rail and / or via a groove-shaped contour portion of the side of the sheet metal profile for accommodating the at least one container bottom, preferably providing that the at least one container bottom is fastened to the sheet metal profile via at least one fixing device.
[0060] In the prior art, the container bottom lies flat on the container rail in a narrow contact area and is arranged without contact with the side frame, wherein the direct contact of the at least one container bottom on the at least one side frame can eliminate the container rail and also ensure a simplified, safe and / or stable connection of the at least one container bottom.
[0061] It has proven to be advantageous if the at least one container bottom is arranged substantially flush with the at least one drawer rail, preferably provision is made for the at least one container bottom to lie flat on the at least one drawer rail.
[0062] If the at least one container bottom lies flat on the at least one drawer rail, an undesired bending of the at least one container bottom can be counteracted by the support for the at least one container bottom formed by the at least one drawer rail. In general, the at least one container bottom can also be arranged with clearance relative to the at least one drawer rail, wherein contact is only made, for example, by the support of the configuration system.
[0063] An advantageous variant provides that the arrangement comprises at least one container rear wall, which is arranged on the at least one rear wall holder.
[0064] Preferably, provision is made that when the configuration system is subjected to loads, preferably vertical and / or lateral loads, in the use state of the configuration system, force transmission can take place directly, preferably without a container rail, between the at least one side frame, preferably the sheet metal profile and / or the at least one front wall bracket and / or the at least one rear wall bracket, and the at least one drawer rail.
[0065] Since a container rail can be omitted, a prolonged force flow can be achieved within the at least one side frame and / or between the at least one side frame and the at least one drawer rail when the arrangement is loaded.
[0066] It is particularly preferably provided that: in a previously prepared method step, at least one crimping hole is introduced into the at least one front wall bracket and / or the at least one rear wall bracket, wherein the at least one crimping portion is formed between the plastic of the at least one front wall bracket and / or the at least one rear wall bracket and the metal of the sheet metal profile, preferably has a substantially circular cross-section, and the at least one crimping portion extends at least partially in the at least one crimping hole of the at least one front wall bracket and / or the at least one rear wall bracket.
[0067] Preferably, the at least one crimping portion is introduced by means of at least one punch or pin, preferably automatically, and it is preferably provided that the metal sheet profile is crimped to the at least one front wall bracket and / or to the at least one rear wall bracket at multiple connection points by means of the crimping portion, and particularly preferably the crimping portion is arranged on the side of the metal sheet profile and / or on the lower side of the metal sheet profile positioned in the use state of the side frame.
[0068] The production outlay for forming the side frames can thereby be reduced, so that a particularly efficient production process can be achieved.
[0069] Preferably, the punch has a preferably conical taper at the free end and / or comprises a diameter which substantially has the extension of the crimping opening minus twice the material thickness of the sheet metal profile.
[0070] According to a preferred embodiment, it is provided that the material of the sheet metal profile is pressed onto the at least one crimping hole so that a force-fitting connection is formed along the at least one crimping hole and / or a form-fitting connection is formed orthogonally to the at least one crimping hole.
[0071] As a result, a particularly secure and stable connection can be produced between the sheet metal profile and the at least one front wall support and / or rear wall support. BRIEF DESCRIPTION OF THE DRAWINGS

[0083] Figure 1a The side frame 1 in the form of a container side wall which is designed as a drawer side wall is shown in an exploded view.
[0084] The side frame 1 comprises a rear wall support 3 , a front wall support 4 and a one-piece bent sheet metal profile 2 in the form of a frame cap, which serves to accommodate the rear wall support 3 and the front wall support 4 .
[0085] The sheet metal profile 2 comprises a groove-like contour 9 on a side surface 8 of the sheet metal profile 2 , which has a substantially rectangular cross section 10 and is designed to receive a container bottom 7 .
[0086] A fixing means 11 in the form of a barb 12 having two teeth 13 (the number of teeth 13 is generally arbitrary) is provided in the profile 9 and serves to connect the container bottom 7 to the sheet metal profile 2 and to fasten the container bottom 7 to the sheet metal profile 2. The fixing means 11 is integrally connected to the sheet metal profile 2, is stamped out of the profile 9 and projects transversely into the profile 9.
[0087] The front wall bracket 4 and the rear wall bracket 3 are in the form of angled pieces 17 (in a plane along the longitudinal extension 15 or in a plane orthogonal to the longitudinal extension 15 ) for being pushed into the sheet metal profile 2 via recesses 18 of the front wall bracket 4 and the rear wall bracket 3 corresponding to the contour 9 of the sheet metal profile 2 .
[0088] Figure 1b The side frame 1 is shown in a partially assembled state before a crimp is introduced on the sheet metal profile 2 for connecting the front wall support 4 and the rear wall support 3 , wherein the rear wall support 3 and the front wall support 4 are arranged within the sheet metal profile 2 .
[0089] Figure 2a It is shown that the front wall support 4 (generally also conceivable on the sheet metal profile 2) comprises a coupling device 5 for coupling to a drawer rail 6 directly and without a container rail (see Fig.10 ).
[0090] Figure 2b The sheet metal profile 2 is shown to be crimped to the front wall support 4 (and optionally also to the rear wall support 3) at a plurality of connection points 19 by crimping 20. The crimping is arranged on the side 8 of the sheet metal profile 2 which faces the drawer rail 6 or the container bottom 7 in the use state 21 of the side frame 1 (see Figure 5b ).
[0091] The further crimping 20 is arranged on the lower side 22 of the sheet metal profile 2 which is positioned adjacent to the side surface 8 in the use state 21 of the side frame 1 (see Figure 5b )superior.
[0092] The crimping 20 is introduced automatically by means of a punch 41 , wherein the punch 41 has a conical taper at the free end, with which the material of the sheet metal profile 2 can be pressed via the crimping opening 36 onto the material of the front wall support 4 .
[0093] The front wall support 4 and the rear wall support 3 are basically made of plastic, wherein the crimp 20 is located between the plastic and the metal of the sheet metal profile 2. The front wall support 4 comprises connection means 39 for the container front part 24 made of metal.
[0094] Figure 3a The process step of introducing the crimp 20 on the underside 22 of the sheet metal profile 2 which is connected to the front wall support 4 is shown.
[0095] Figure 3b It is shown that the sheet metal profile 2 has a width 16 which is between 4 mm and 6 mm. A crimp 20 has been introduced so that the side frame 1 can be connected directly to the drawer rail 6 .
[0096] The crimping 20 on the underside 22 produces a flat underside 22. The crimping on the side surface 8 is arranged within the contour 9 and is covered by the container bottom 7 after the container bottom 7 has been connected.
[0097] Figure 4a It is shown that the crimp 20 has a circular cross section 40 and extends completely over the material thickness of the sheet metal profile 2 and is formed by the material contact of the sheet metal profile 2 with the material of the front wall support 4 or with the rear wall support 3 .
[0098] Figure 4b Different from Figure 4a The only difference is that the punch 41 has been removed from the crimping hole 36 .
[0099] The crimping portion 20 partially extends in the crimping hole 36 of the front wall bracket 4 (or the rear wall bracket 3 ).
[0100] The depth 37 of the crimping portion 20 is between 10% and 50% of the depth 38 of the crimping hole.
[0101] Figure 5a An enlarged detail of the side frame 1 is shown in the region of the rear wall support 3 .
[0102] A method for manufacturing the side frame 1 can be described as follows by way of example (without absolute time relevance):
