Description

Field of the Invention

[0001] The present invention relates to an adapter unit for connecting a drawer bottom to a side frame of a drawer as described in the preamble of claim 1. The present invention also relates to a side frame for a drawer and a drawer. Background Art

[0002] To fix a drawer bottom to the side frame of a drawer, an adapter is known which can be fastened to the side frame and has claws with teeth integrally formed on the adapter, the claws protruding from a support member integrally formed on the adapter from a support surface of the drawer bottom, such that when the drawer bottom is inserted onto the adapter, one or more teeth are engaged in the underside of the drawer bottom and thus the drawer bottom is held in a position-fixed manner.

[0003] Such an adapter unit is known, for example, from DE 10 2012 107 572 A1.

[0004] In this adapter unit, the adapter is made of sheet metal and the claws can be bent out of the sheet in a simple manner.

[0005] If such an adapter is not made of sheet metal, it is difficult to connect such claws to the adapter in a suitable manner. Summary of the Invention

[0006] Accordingly, it is an object of the present invention to provide an adapter unit by means of which claws for fixing a drawer bottom can be attached to the adapter in a simple manner.

[0007] This object is achieved by an adapter unit according to one aspect of the present invention, a side frame according to another aspect of the present invention, and a drawer according to yet another aspect of the present invention.

[0008] The adapter unit for connecting a drawer bottom to a side frame of a drawer according to the present invention has an adapter which has a forming part for connection to a frame wall of the side frame, and a support member having a support surface extends at an angle, in particular at a right angle, from the forming part to support the drawer bottom.

[0009] The adapter unit also has at least one claw arranged in the support member, the at least one claw having at least one tooth which can be pressed into the drawer bottom.

[0010] The claw is designed as a sheet claw which can be mounted on the support member, and the support member has a receiving space for receiving the sheet claw, and the sheet claw can be mounted in the receiving space without tools.

[0011] By means of such an adapter unit, the sheet claw can be mounted on the support member of the adapter without tools.

[0012] Advantageous embodiment variants of the present invention are other aspects of the present invention.

[0013] According to an advantageous embodiment variant of the present invention, the support member is cubic in shape, and at least one opening is provided in a side surface of the support member that forms a support surface, and in the assembled state of the sheet claw, the at least one tooth projects from the at least one opening.

[0014] Such a cubic support member provides the possibility of locking the sheet claw in an extremely simple manner.

[0015] According to a further advantageous aspect, the opening from which the at least one tooth projects is preferably designed in a window shape or a slot shape.

[0016] According to another advantageous embodiment variant, the sheet claw has a locking region, a bending region extends from the locking region, and the at least one tooth is integrally formed on the bending region.

[0017] This achieves a separation of the locking and gripping functions, such that the sheet claw can first be locked onto or into the support member, and then the at least one tooth can be bent in a desired direction.

[0018] According to a further advantageous aspect, the locking region of the sheet claw is designed as a plane and has at least one latching element projecting from the plane, and the at least one latching element can be latched with a matching latching element of the support member.

[0019] According to a preferred further aspect, the latching element is designed as a latching lug that projects angularly from the plane of the locking region, and in the latched state, the latching lug projects into a latching element of the support member designed as a latching recess.

[0020] According to a preferred further aspect, the latching element designed as a latching recess is formed in a wall of the support member perpendicular to the support surface.

[0021] In an alternative embodiment variant, the latching element designed as a latching recess is formed in a wall section of the support member that is offset parallel to the support surface, and the locking region of the sheet claw is placed on the wall section.

[0022] This makes it easy to place the sheet claw and then press it into a receiving space of the support member provided for this purpose.

[0023] The distinctive feature of the side frame for a drawer according to the present invention having an adapter unit with a frame wall for connecting a drawer bottom to the side frame lies in the adapter unit as described above.

[0024] The uniqueness of the drawer according to the present invention lies in at least one side frame as described above. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] In the following description of the drawings, terms such as top, bottom, left, right, front, and back specifically refer to the exemplary representations and positions of adapters, side frames, supports, support surfaces, sheet claws, etc. selected in the respective drawings. These terms should not be understood restrictively, i.e., these references may change due to different working positions or mirror-symmetric designs, etc.

[0038] In Figure 1 and Figure 3 , the reference numeral 1 as a whole represents an embodiment variant of the side frame of a drawer 10 according to the present invention, which is shown by way of example in Figure 15 to which an adapter unit is attached for connecting the side frame to a drawer bottom 11.

[0039] The drawer 10 has two such side frames 1 to which the drawer bottom 11 is fixed via its adapter unit. A front panel 12 is arranged at the front of the drawer 10.

[0040] The adapter unit has an adapter 5 with a molding part 6 on a frame wall 2 for connection to the side frame 1.

[0041] In the embodiment variant shown here, the side frame 1 preferably includes a core 21 hidden by an inner wall 22 with a smooth surface facing the interior of the drawer and an outer wall 23 facing away from the interior of the drawer.

[0042] The outer wall 23 of the side frame 1 surrounds the molding part 6 of the adapter 5, such that the latter is additionally advantageously held on the side frame 1.

[0043] At the front end observed in the longitudinal direction of the frame wall 2, a running rail connector 3 is attached to an adapter device not described in detail for engagement with the rail guide of the drawer 10.

[0044] The flat molding part 6 of the adapter 5 aligned parallel to the frame wall 2 abuts against a support 7 with a support surface 71 for supporting the drawer bottom 11.

[0045] The teeth 41 of a sheet claw 4 mounted on the support 7 project from the support surface 71.

[0046] For this purpose, the support 7 has a receiving space 73, as shown by way of example in Figure 4 for receiving the sheet claw 4, and the sheet claw 4 can be installed therein without tools.

[0047] As Figures 1 to 4 further shown, the shape of the support 7 is preferably cubic.

[0048] At least one opening 72 is provided in the side surface of the support 7 forming the support surface 71, and in the assembled state of the sheet claw 4, at least one tooth 41 of the sheet claw 4 projects from the at least one opening.

[0049] Different exemplary variants of the sheet claws 4, 8, 9 are described below based on Figures 5 to 14 and are inserted into the correspondingly shaped receiving spaces 73 of supports 7 of different designs.

[0050] All different exemplary variants of the sheet claws 4, 8, 9 have in common that they have locking regions 42, 82, 92 from which bending regions 43, 83, 93 extend, and at least one tooth 41, 81, 91, in this exemplary embodiment two teeth 41, 81, 91 each or both are formed in the bending region.

[0051] The locking regions 42, 82, 92 of the sheet claws 4, 8, 9 are preferably designed as planes and have at least one latching element 45, 85, 95 which projects from the surface and can be latched with the mating latching elements 78, 79 of the support 7.

[0052] In Figures 5 to 8 the first preferred exemplary variant shown, the locking region 42 of the sheet claw 4 is of substantially rectangular shape and has a width perpendicular to the insertion direction Z in the longitudinal extension direction X, which width is greater than the width of the bending region 43 from which the tooth 41 projects.

[0053] Thus, the groove-shaped receiving space 73 is provided in the support 7 by the contact bar 74 and the guide bar 76 and the front wall of the support 7 facing the inside of the drawer, and the sheet claw 4 can be inserted into it from the lower side of the support 7 facing away from the support surface 71.

[0054] To lock the sheet claw 4, in the exemplary embodiment shown, the latching element 45 is centrally provided on the locking region 42, and the latching element is designed here as an angled latching lug which, in the latched state, projects into the latching element 79 designed as a latching recess. The latching element 79 designed as a latching recess has a slot-shaped design corresponding to the slot-shaped design of the latching element 45.

[0055] Figure 5 A sliding surface 44 in the locking region 42 is also shown, which facilitates the assembly of the sheet claw 4.

[0056] Starting from the edge of the locking region 42 near the support surface 71 in the assembled state, the bending region 43 extends in an arc, and after the sheet claw 4 is inserted into the receiving space 73 of the support 7, if necessary, it can be further pressed into the opening 72 in the support surface 71 from below, for example, with a finger or a tool.

[0057] The contact bar 74, the support bar 75, and the guide bar 76 are also used to stabilize the cube support 7, as shown by way of example in Figure 6 the example.

[0058] In Figures 9 to 11 the illustrated embodiment variant of the sheet claw 8, the sheet claw 8 is of a clip-like or U-shaped design, where two teeth 81 are integrally formed on one of the legs of the U, which in the assembled state project through the opening 72 in the support surface 71 of the support 7.

[0059] The sheet claw 8 is also inserted into the receiving space 73 of the support 7 from the lower side facing away from the support surface 71.

[0060] In the assembled state, the bending region 83 (the central bar of the U) is placed on the contact bar 74 that projects from the lower side of the support surface 71 here, and the contact bar is designed to be inclined downward at an angle with respect to the bending region 83 of the sheet claw 8, such that after the sheet claw 8 has been inserted into the receiving space 73, the tooth 81 can be further bent forward through the opening 72, so that the tooth 81 projects further out of the support surface 71 of the support 7.

[0061] On the leg of the sheet claw 8 opposite to the tooth 81 that forms the locking region 82, at least one tongue-shaped latching element 85 is integrally formed, which in the assembled state projects into Figure 10 the illustrated latching element 79, which is also formed as a slot-shaped latching recess, and when the sheet claw 8 is pressed into the receiving space 73, the latching recess projects into this latching recess.

[0062] In Figures 12 to 14 the illustrated embodiment variant, the receiving space 73 for receiving the sheet claw 9 is designed as a wall section 77 that is offset parallel to the support surface 71 from this support surface and has an opening 72 set centrally, and the sheet claw 9 is placed on this wall section from above.

[0063] The parallel offset corresponds to the material thickness of the sheet claw 9, such that the upper side of the locking region 92 of the sheet claw 9 is flush with the support surface 71 of the support 7.

[0064] The locking region 92 of the sheet claw 9 is formed here to be frame-like.

[0065] On the relatively narrow side of the locking region 92, a locking lug that projects downward at an angle from the plane of the locking region 92 is also formed here as a latching element 95, which in the latched state can be latched into a latching element 78 that is also formed here as a slot-shaped latching recess.

[0066] A bent region 93 extends within the frame-shaped locking region 92, and teeth 91 are formed at the end of the bent region.

[0067] Here, the bent region 93 is of a substantially arcuate shape, where the bent region 93 initially extends from the frame-shaped locking region 92 into an opening 72 in the support surface 71 of the support 7, and the teeth 91 integrally formed on the free end of the bent region 93 project upward out of the support surface 71.

[0068] This embodiment variant also allows the simple installation of the sheet claw 9 on the support 7 of the adapter 5 without tools.

[0069] In all embodiment variants, to lock the sheet claws 4, 8, 9 to the drawer bottom 11, it can be simply pressed manually or with tools in the direction of the bottom.
