Technical Field
[0001] This invention relates to a drawer comprising a bottom plate, a front panel, two side frames, and a rear wall forming an internal space of the drawer. The internal space is normally open at the top and closed at the bottom by the bottom plate. Each side frame includes an integral inner wall having a groove-shaped receiving portion integrally formed for the drawer bottom plate. The receiving portion is channel-shaped and includes two generally horizontal grooved side walls, with a generally vertical grooved base arranged between the two grooved side walls. Each side frame also includes an outer wall mounted on the inner wall, wherein the inner and outer walls enclose a cavity forming a cavity of the side frame, and each cavity includes at least one support member, the support including a retaining section. Further, this invention relates to a method for manufacturing a drawer. Background Technology
[0002] DE102019107867A1 illustrates a drawer with a side frame, the side frame including bent wall elements such that they integrally form the inner and outer walls of the side frame. A receiving portion for the drawer bottom is formed in the inner wall, the receiving portion including a support device for the bottom, in which a recess is formed toward the bottom, and at the recess, the outer wall has a connection to the drawer bottom.
[0003] Some drawers also have side frames that include adapter devices to which the drawer's front panel can be mounted. To accommodate heavier loads, the adapter device can be fastened to a support member operably connected to the side frame. WO2016 / 156049A1 illustrates such a drawer, where the side frame has a support member for the front panel, which is fastened to a wall element of the side frame. The wall element includes a slotted receiving portion for the drawer bottom, and an insertion device for the support member is disposed outside this receiving portion. The support member is inserted into this insertion device, which includes two channels formed in the wall element.
[0004] In the prior art, the problem is that the wall elements of the drawer's side frame bear the force of the support and are subjected to high stress, and manufacturing the side frame requires a large amount of material. Summary of the Invention
[0005] Therefore, the object of the present invention is to provide an improved drawer.
[0006] The present invention solves this problem by having a drawer having the features of claim 1 and a method for manufacturing the drawer having the features of claim 17.
[0007] The drawer of the present invention includes a base plate forming an internal space, a front panel, two side frames, and a rear wall. The internal space is open at the top and closed at the bottom by the base plate. Each side frame includes an integral inner wall having a groove-shaped receiving portion integrally formed for the drawer base plate. The receiving portion is channel-shaped and includes two generally horizontal grooved sidewalls. A generally vertical grooved base is arranged between the two grooved sidewalls. Each side frame also includes an outer wall mounted on the inner wall. The inner and outer walls surround a cavity of the side frame. Each side frame includes at least one support within the cavity, the support including a retaining section. The grooved base includes a contact surface for an end face of the base plate, the contact surface projecting from at least one recess toward one of the end faces of the base plate. The retaining section is fastened to the contact surface on a side opposite to the grooved base, and at least one of the at least one recess at least partially abuts against a separate outer wall, which allows the retaining section to be mounted to the inner wall of the side frame particularly easily. When the drawer is installed, the force transmitted from the retaining section of the support to the base of the recess is directly transferred from the inner wall to the bottom plate through the receiving channel, thereby relieving stress on the inner wall above the receiving channel. Furthermore, the drawer according to the invention includes features for dissipating and / or transmitting forces from the retaining section of the support to the base of the recess, resulting in particularly high stability and allowing for more efficient material forming of the drawer. Using the invention, the drawer bottom plate can be installed in a precisely fitted manner, wherein at least one recess increases the stability of the receiving portion. Preferably, the recess can be used to support the outer wall and / or maintain the distance between the outer wall and the contact surface.
[0008] The side of the contact surface away from the bottom of the groove is the side of the contact surface that is not in the receiving part, and the drawer bottom plate is inserted into or slid into the receiving part.
[0009] The retaining section is preferably located adjacent to the recess, that is, on the side of at least one recess in the pull-out direction. A receiving portion or recess may be arranged in place of the recess within the region of the retaining section.
[0010] To enable a particularly precise and space-saving fastening of the retaining section of the support to the base of the recess, at least one of the recesses preferably includes at least one orifice for each support through which the support (particularly the retaining section) passes. In this case, at least one recess is arranged to protrude beside the retaining section, for example, to space the outer wall from the support. For example, the upper recess may include at least one orifice for each support. By passing the support or the retaining section of the support through the upper recess, it is ensured that the retaining section does not protrude beyond the outer contour of the upper recess. Thus, the outer wall does not abut against the retaining section, or at least not entirely against it, but is at least partially supported by at least one of the at least one recess over the entire length of the side frame. The at least one recess may include the same cross-section over its entire length, or alternatively, may have embossing protruding toward the outer wall at one or more locations, with the outer wall abutting against these embossings.
[0011] The recesses can be formed continuously without openings in the longitudinal direction, making them particularly easy to manufacture. Preferably, openings are present at both recesses. For example, at least one opening for a base plate claw can be provided at the recess. In an alternative arrangement, each retaining section is located in an opening for each recess, allowing the support to be particularly well secured to the inner wall and preventing torsion.
[0012] Specifically, the outer wall comprises a wall thickness thinner than the inner wall, for example, at least 10% thinner. In particular, the outer wall significantly reduces stress due to the transfer of external forces to the support members and their dissipation through the inner wall to the base plate, as well as the absorption of additional forces by the inner wall. Thus, the side frame can be configured to be particularly material-efficient and narrower in the vertical direction relative to its main longitudinal extension direction, while maintaining stability.
[0013] Particularly preferred is that, for particularly narrow designs of the side frames, the inner walls have a corresponding wall thickness of 0.6 mm to 1 mm, and the outer walls have a corresponding wall thickness of 0.4 mm to 0.8 mm. Crucially, the inner wall of each side frame has a greater wall thickness than the corresponding outer wall because components absorbing the forces of the main system (such as supports and connecting devices) are arranged on the inner wall. The base material for the inner walls, outer walls, and at least one support is preferably steel plate, respectively.
[0014] The retaining section of at least one support member is preferably fastened to the receiving portion of the inner wall at the base of the groove by means of force and form fit or material locking, preferably by means of press-fit or welding, to ensure particularly robust embodiments of the side frame.
[0015] In a preferred embodiment, the retaining section is fastened to the contact surface by form fit and / or force fit or material locking. By fastening the retaining section to a portion of the recess base, when the drawer or base plate is in the installed state, the force acting on at least one support member can be transferred to the recess base through the retaining section. The base plate inserted into the receiving portion prevents significant deformation of the receiving portion, or transfers a portion of the force acting on at least one support member to the base plate. This arrangement significantly reduces the inner wall above the recess base, thereby improving stability. In a preferred embodiment, the retaining section includes only one leg. In another preferred embodiment, the retaining section of the support member includes at least two legs, each leg being at least partially arranged in one or a separate opening in at least one recess, and each leg is preferably connected to the contact surface of the recess base or another segment of the recess base by crimping or welding.
[0016] At least one recess preferably extends along the entire length of the base of the recess, particularly at its edge parallel to the drawer's pull-out direction. The drawer's pull-out direction corresponds to the longitudinal extension direction of the side frame. This allows the drawer's bottom plate to be particularly securely fixed and precisely positioned.
[0017] Therefore, the receiving portion preferably also includes at least two recesses that extend generally parallel to each other, so that the bottom plate of the drawer can slide into the receiving portion until it contacts the surface, without being blocked by the curved edge of the base of the recess.
[0018] The recess is preferably formed at the transition from the base of the groove to the sidewall of the groove to facilitate the manufacture of the receiving portion. Alternatively, the recess may be optionally located in the central region of the bottom of the groove. Preferably, multiple recesses are arranged in a row in the central region.
[0019] Preferably, the recesses extending generally parallel to each other comprise a U-shaped cross-section, wherein the first leg of the U-shape transitions to the contact surface, and the second leg of the U-shape transitions to the recess sidewall of the groove-shaped receiving portion. A gap is formed between the generally parallel recesses, particularly in the range of 6 mm to 22 mm, preferably in the range of 9 mm to 18 mm, to optimize for the available drawer bottom. Preferably, the recesses comprise a U-shaped or V-shaped cross-section parallel to the direction in which the bottom plate is inserted into the receiving portion.
[0020] For a particularly stable version of the side frame, the contact surface of the groove base occupies at most 95%, preferably at most 85%, of the groove base of the receiving portion (i.e., the area of the receiving portion), and is preferably arranged between generally parallel recesses. Therefore, the area of the recesses includes only 5% to 15% of the bottom of the groove.
[0021] In another preferred embodiment, the recesses form contact surfaces for the outer walls on their respective sides opposite the drawer bottom. The recesses extend substantially parallel to each other and can serve as contact surfaces; however, additional recesses may also be provided, which additionally or specifically form contact surfaces for the outer walls. The additional recesses are preferably arranged between the recesses that extend substantially parallel to each other. Preferably, the additional recesses are segmented along the base of the recess. In particular, the additional recesses are formed as bridges or embossing extending toward the outer wall. Optionally, the additional recesses (such as embossing) protrude further from the base of the recess compared to the recesses that extend parallel to each other.
[0022] The side frame has a width at its thickest point above the receiving section, perpendicular to the direction of the drawer's pull-out and generally parallel to the bottom of the drawer, preferably ranging from 7 mm to 14 mm, more preferably from 10 mm to 13.5 mm, and most preferably less than 12 mm, to particularly save space and resources.
[0023] For ease of operation, the weight per unit area of the side frame is preferably less than 14 kg / m², particularly preferably less than 13 kg / m², and even more preferably less than 12 kg / m². The weight per unit area is preferably calculated based on the area of the side frame, which is the longitudinal extension of the side frame (corresponding to the length of the side frame in the drawer pull-out direction) multiplied by the total height of the side frame.
[0024]
[0025] Preferably, the at least one support member includes a plate-shaped main section extending in the insertion direction of the base plate, offset from the retaining section by the profile, and the main section is specifically arranged adjacent to the receiving portion in the height direction of the side frame, such that the retaining section is arranged on one side of the profile and the main section is on the other side of the profile.
[0026] In one embodiment, at least one support member of the side frame may further include at least one support device connected to the shape of the main plate segment, such that forces acting on the main segment can be transmitted to the inner wall through the support device. This allows the side frame to maintain dimensional stability even in the upper region and prevents unnecessary contact between the support member and the inner wall.
[0027] Preferably, the outer wall is substantially plate-shaped and includes a fastening section designed as a support device in its upper region. Through this fastening section, the outer wall is form-fitted to the upper part of the inner wall of the corresponding side frame, allowing the outer wall to be installed in the upper region without any additional fasteners. Particularly preferably, the outer wall in each case includes a fastening section designed as a support device, which is bent and deviates from the generally plate-like shape, forming most of the outer wall in the height direction of the side frame. Thus, the outer wall is fixed to the inner wall by a form-fit connection. For this purpose, the inner wall includes a corresponding fastening section in its upper portion, designed as a support device. This makes the connection between the outer and inner walls of the upper region side frame particularly simple. For example, the outer and inner walls include U-shaped cross-sections in the bent sections, such that the U-shaped sections overlap each other in a form-fit manner to achieve fastening of the wall elements to each other.
[0028] In a particularly preferred embodiment, the inner wall also includes an integrally formed protrusion for particularly easy mounting of a pull-out guide below the receiving portion. For example, a guide rail for the pull-out guide may be fixed to the protrusion, or a connecting device for fixing the pull-out guide may be arranged on the extension.
[0029] In another preferred embodiment, the outer wall is secured to the receiving portion or protrusion of the inner wall by press-fitting and / or welding, particularly to the lower recess sidewall. Supports are arranged on the inner wall, thus positioning them between the inner and outer walls, i.e., within the cavity of the side frame. This allows the side frame to be designed with enhanced stability and particularly easy installation, while achieving a visually appealing appearance. In the lower region, the outer wall specifically includes an inclined section, which is preferably secured to the lower recess sidewall.
[0030] In an optional embodiment, the retaining section and / or outer wall are each secured to the receiving portion of the inner wall, such that all three components can be secured using the same highly reliable connection method. Preferably, the connection method is a press-fit connection, wherein the connection is formed solely through pure deformation processing of corresponding pairs of sheet metal parts.
[0031] Preferably, the protrusion includes a connecting device for securing it to the guide rail of the drawer's pull-out guide, thereby allowing advantageous and easy attachment to the corresponding side frame. This also allows for the implementation of a bottom guide, creating a visually appealing side frame appearance.
[0032] Preferably, the base of the support member, including the main section, has a wall thickness of 0.6 mm to 1.6 mm, thereby enabling the support member to preferably support the corresponding inner wall of the side frame. Other components, particularly those formed as connecting devices, are arranged on at least one support member. Thus, the support member forms an assembly whose overall width is greater than the wall thickness of the base.
[0033] At least one support device may specifically include a generally U-shaped section to ensure dimensional stability of the support device and to allow it to wind around at least one side of the support member, particularly around the main section, for establishing a form-fit connection. In another embodiment, at least one support device preferably includes at least one protrusion through which forces acting on the corresponding outer wall of the side frame can be transmitted to the support member. This results in particularly high stability of the outer wall.
[0034] In a particularly preferred embodiment of the invention, each side frame includes at least two supports, each support including a connecting device. The front panel is fastened to the connecting device of one support, and the rear wall of the drawer is fastened to the connecting device of the other support.
[0035] As is known in the prior art, the base plate may be secured by nails, pins, screws, and / or base plate claws.
[0036] Specifically, the inner wall of the side frame can be arranged and / or fastened to a drawer bottom plate, preferably plate-shaped, such that the outer wall of the side frame is arranged substantially perpendicular to the bottom plate. The bottom plate is preferably inserted into a corresponding receiving portion of the side frame and abuts against the contact surface substantially without openings.
[0037] Preferably, the front panel is detachably held on each main section of at least one of the supports on each side frame via an adapter or front panel adapter. In this case, the front panel adapter is secured to the side frame together with the front panel after the connecting device is inserted, so that the front panel can be easily adjusted or readjusted. Adjustment devices may be provided on the connecting devices on the supports. Alternatively or additionally, adjustment devices may be provided on the front panel adapter. The adjustment devices on the front panel adapter and / or the main sections or supports allow the front panel to be adjusted relative to the respective side frame.
[0038] Preferably, the rear wall is held in place by a connecting device arranged on the main section of the corresponding second support member of the side frame. This connection can be detachable. In this case, after the connecting device is inserted, the rear wall is secured to the side frame, making the position of the rear wall stable and preventing movement relative to the side frame. An adjustment device can be provided on the rear wall and / or the main section to adjust the drawer relative to a pull-out guide. The adjustment device on the rear wall and / or the main section is connected independently of the rear wall, so that adjustment of the adjustment device does not affect the position of the rear wall relative to the side frame. The adjustment device can be provided on a connecting device on the second support member. Alternatively and / or additionally, the adjustment device can be provided on the rear wall.
[0039] To simplify the manufacture of drawers and ensure their stability, this invention also relates to a method for manufacturing drawers, comprising the following steps:
[0040] a. Positioning at least one support on one of two inner walls, each inner wall including a groove-shaped receiving portion for a drawer bottom plate, the receiving portion being channel-shaped and including two generally horizontal groove sidewalls, with a generally vertical groove base arranged between the two groove sidewalls;
[0041] b. Inserting, in particular introducing and pivoting at least one retaining section of the corresponding support member so as to arrange at least one support member in a form-fitting manner on the corresponding inner wall;
[0042] c. Fasten at least one retaining section to the contact surface of the receiving portion by pressing or welding, the contact surface being for the corresponding end face of the base plate, the contact surfaces protruding from at least one recess toward the end face of the base plate, located on the side opposite to the groove base of the receiving portion;
[0043] d. Fasten the corresponding outer walls to the corresponding inner walls by shape and / or friction fit to form two side frames;
[0044] e. Assemble the two side frames, front panel, and rear wall to the bottom plate to form the interior space of the drawer, which is open at the top and closed at the bottom by the bottom plate in the direction of the drawer's travel.
[0045] Preferably, steps a to d are used to form two side frames. For through-fastening, bolts without a cylindrical cross-section are used in particular.
[0046] Preferably, the method further includes the following steps:
[0047] f. Forming at least one opening in at least one of at least one recess;
[0048] g. Arrange appropriate supports and / or retaining sections in at least one orifice. Attached Figure Description

The inner wall 11 includes an integrally formed groove-shaped receiving portion 114, which is used for... Figure 1a The drawer 2 has a bottom plate 4 (not shown). The receiving portion 114 is channel-shaped and includes two generally horizontal recessed sidewalls 1151 and 1152, between which a generally vertical recessed base 115 is arranged. The recessed base 115 includes a contact surface 116 that protrudes toward either the end face of the bottom plate 4 or toward the opening of the receiving portion 114. Figure 1a The opening is inserted into the recess. The groove base 115 includes at least one recess 117, wherein at least two recesses 117 are formed that are arranged parallel to each other, or two recesses 117 are formed that are partially interrupted by the orifice 118. The contact surface 116 is arranged between the recesses 117 that extend parallel to each other.
[0068] Support member 13 is arranged on side frame 1 and includes a retaining section 131 forming two legs and a plate-shaped main section 133 biased by profile 134. Support device 132 is mounted on main section 133, through which force can be transmitted from inner wall 11 to support member 13 and vice versa. As shown, recess 117 includes a plurality of orifices 118 in the upper region of recess base 115, in which retaining section 131 of support member 13 is arranged. Retaining section 131 is fastened to the side of contact surface 116 opposite to recess base 115 and therefore opposite to bottom plate 4 of drawer 2.
[0069] In the illustrated configuration, a crimp connection is provided for securing the retaining section 131 to the contact surface 116. The retaining section 131 includes at least one connection point at each of its respective legs. However, more or fewer such crimp connections may be used, or alternatively, welding may be employed. The retaining section 131 may also include only one leg.
[0070] from Figure 1b As can be seen, the inner wall 11 on one side of the receiving portion 114 (arranged at the bottom of the figure) includes an integrally formed protrusion 119 below the receiving portion 114 for connecting device 1191 (not shown), which is used to connect device 1191 for... Figure 1a Pull-out guide for middle drawer 2.
[0071] In addition, an opening 7 is provided in the inner wall 11. When the side frame 1 is installed, this opening 7 allows the support 13 and any adjusting or releasing elements to be operated from inside the drawer 2. Optionally, this opening 7 can be covered by a cover plate 71.
[0072] Figure 2a It shows Figure 1a A top view of the side frame 1 of drawer 2, viewed from the front panel 3 of the drawer. This side frame is arranged on the left side of the rear wall 5, looking towards the receiving portion 114 in the direction from the inner wall 11 to the outer wall 12 and the support member 13. The support member 13 can be seen through an optional opening 7 in the inner wall 11, which corresponds to... Figure 1a The optional opening has a cover plate 71. According to all the embodiments shown, the weight per unit area of the side frame 1 is preferably less than 14 kg / m². 2 Even more preferred is less than 13 kg / m 2 The weight per unit area is calculated relative to the area of side frame 1, which corresponds to its longitudinal extension L or the side frame length L multiplied by its side frame height H, such as... Figure 2a As shown, the length L corresponds to Figure 1a The length of the side frame 1 of the middle drawer 2 in the direction of pulling out.
[0073]
[0074] Figure 2b It shows Figure 2a As shown in the figure, the cross-section A of the side frame 1 has the inner wall 11 fastened to the outer wall 12 in the upper region. The inner wall 11 and the outer wall 12 form a cavity in the side frame 1. Figure 2b Also shown is a power accumulator 14 on the support member 13, which is disposed in the cavity of the side frame 1, through which the power accumulator on the support member 13... Figure 1a The invisible connecting device 141 locks the front panel 3 to the side frame 1. The support device 132 is fitted to the main section 133 in a form-fit manner.
[0075] The support member 13 is disposed between the inner wall 11 and the outer wall 12, that is, within the cavity of the side frame 1. The retaining section 131 of the support member 13 is fastened to the side opposite to the contact surface 116 by pressing it against the side away from the groove base 115. The side frame 1 is fastened to the receiving portion 114. Figure 1a The bottom plate 4 of the middle drawer 2. The bottom plate 4, not shown in this figure, is for insert receiving portion 114 and rests flush against contact surface 116. The outer wall 12 at least partially abuts against groove 117 of groove base 115 of inner wall 11.
[0076] The outer wall 12 is essentially plate-shaped and includes a fastening section 121 in its upper region, which is formed as a support device to fasten it to the corresponding fastening section 111 of the inner wall 11.
[0077] Figure 2c The area of the inner wall 11, including the contact surface 116, is shown. It can be seen that the groove base 115 includes at least two recesses 117, and the support 13 includes a profile 134. The retaining section 131 passes through an aperture 118 in at least one of the recesses 117 (here, the upper one) and abuts substantially without aperture against a side opposite to the groove base 115 (i.e., the rear side of the contact surface 116). Figure 2c An enlarged view is shown, illustrating that the retaining section 131 is connected to the recess base 115 by a crimp or press-fit connection. For crimping, a pin with an off-circular cross-sectional profile is preferred to provide anti-rotation protection for the connection. Alternatively or additionally, welding may be used for fastening. The outer wall 12 supports abutting against a recess 117 in the recess base 115, such that the recess 117 and the orifice 118 form a space between the inner wall 11 and the outer wall 12 for the retaining section 131.
[0078] from Figure 2b and Figure 2c As can be seen from the image, the recess 117 includes a U-shaped cross-section. One leg of the U-shape extends into the contact surface 116, and the other leg extends into the recess sidewall 1151 or 1152, which extends substantially perpendicular to the contact surface 116. The bottom of the recess 117, i.e., the arch of the U-shape, may optionally be slightly flattened, such that the outer wall 12 is flush with the recess 117.
[0079] Figure 2d It shows Figure 2a The cross-section B of the middle side frame 1. A second support member 15, including a stepped profile 154, is arranged within the cavity of the side frame 1. The support member 15 is supported by the profile 154 on the recessed sidewall 1151 of the housing 114. A main section 153 is formed on one side of the profile 154 above the receiving portion 114, and a retaining section 151 of the second support member 15 is formed on one side of the profile 154 on the left side of the receiving portion 114. Figure 1a In the middle, the rear wall 5 of drawer 2 is fastened to the second support member 15. The outer wall 12 is fastened to the groove side wall 1152 of the receiving portion 114 of the inner wall 11 by crimping and / or welding.
[0080] In the direction perpendicular to the outer wall 12, particularly perpendicular to its main, i.e., largest plate-like cross-section, the side frame 1 includes a width of 7 mm to 14 mm, preferably 10 mm to 13.5 mm, and most preferably less than 12 mm, above the receiving portion 114. The inner wall 11 preferably includes a wall thickness of 0.6 mm to 1 mm, and the outer wall preferably includes a wall thickness of 0.4 mm to 0.8 mm. The support member 13 and / or the second support member 15, or optionally at least one additional support member not shown herein, may optionally include a wall thickness of 0.6 mm to 1.6 mm.
[0081] Figure 2e It shows Figure 2a The cross section of the side frame 1, wherein the inner wall 11 and the outer wall 12 are connected to each other by two fastening sections 111, 121 through form fit and / or force fit.
[0082] like Figure 2e As shown, the inner wall 11 includes a fastening section 111, which is arranged in a form-fitting manner within the fastening section 121 of the outer wall 12.

In this illustration, the mating profile 166 is not yet engaged with the engagement profile 165.
[0105] like Figure 14c as well as Figures 14d to 14g As shown, in the next step, the support 16 then swings its upper region onto the fastening section 111, so that it is held within the inner wall 11' in a form-fitting manner.
[0106] Figure 14e A support 16 is shown, the retaining section 161 of which is press-fitted to the contact surface 116 of the receiving portion 114 below the profile 164. Thus, the retaining section 161 passes through at least one orifice 118 in the recess 117.
[0107] Figure 14f The enlarged view shows how the support member 16 is arranged on the inner wall 11' of the fastening section 111 by the support device 132 connected to the main section 163. Figure 14gA support 16 is shown arranged on the inner wall 11'. Subsequently, another support is installed at the opposite end of the side frame 1 in the same manner, its retaining section passing through the free hole 118. In a further step, an outer wall 12 (not shown) is arranged on the inner wall 11' to form the side frame 1. The drawer's rear wall 5 and bottom plate 4 are mounted on the side frame thus formed. In a subsequent step, the front panel 3 is mounted at least on the side frame 1, thereby forming the drawer's interior space, which is open on the top side and closed on the bottom side by the bottom plate 4. The drawer thus formed substantially corresponds to Figure 1a Drawer 2 in the middle.
