Description

[0001] drawer

[0002] The present invention relates to a drawer with a base, two side frames and a rear wall connecting the side frames, which is made at least at the ends from a bent metal sheet, and a substantially first vertical wall section, on the top side of which there is a substantially horizontal fold and on the underside of which there is a step with a substantially second vertical wall section, wherein the second vertical wall section is spaced apart in the horizontal direction from the first vertical wall section and the step encloses a rear edge of the base, and an adjusting device for adjusting the inclination of the drawer relative to a guide rail of a pull-out guide with a support arranged on the first vertical wall section, on which support an adjusting element is held displaceably or pivotably, which can be driven by a rotating part held on the support.

[0003] WO 2020 / 164959 A1 discloses a drawer with a rear wall on which an adjustment device is provided for adjusting the inclination of the drawer relative to a rail of a drawer slide. For this purpose, a pressure rod is slidably mounted on a housing of the adjustment device, which is adjustable via an eccentric on a rotating part. The pressure rod is supported on the rail directly or via a piston and thus penetrates an opening or recess in a lower area of ​​the rear wall, which leads to a weakening of the rear wall. Furthermore, the base is not mounted on the rear wall, which allows the base to sag significantly when loaded.

[0004] It is therefore an object of the present invention to provide a drawer with an adjustment device for tilt adjustment, which has a stable construction and is easy to assemble.

[0005] This object is achieved with a drawer having the features of claim 1.

[0006] In the drawer according to the invention, an adjustment device is provided for adjusting the inclination of the drawer relative to a guide rail of a pull-out guide, which comprises a support arranged on the first vertical wall section, on which support an adjusting element is held displaceably or pivotably and is drivable by a rotating part held on the support, wherein the adjusting element has an adjusting foot which can be supported on the guide rail of the pull-out guide and which is arranged horizontally next to and not within a step. The rear wall comprises a first essentially vertical wall section and a second essentially vertical wall section which is spaced horizontally from the first vertical wall section via the step, wherein the step encloses a rear edge of the base.The adjustable foot therefore does not penetrate the material of the back panel at an opening or recess, but is positioned adjacent to the back panel, specifically next to the step of the back panel that rests against the floor. This allows the drawer to have a stable structure in the area of ​​the back panel and allows for easy handling by rotating the adjusting element for tilt adjustment via the rotating part.

[0007] The rear wall is made of a bent metal sheet, at least at its ends, and has a substantially horizontal bevel on the upper side of the first substantially vertical wall section. Preferably, the support is held between the horizontal bevel and the step. The horizontal bevel and the step form a receiving space on the rear wall, which is used for arranging the adjustment device, enabling a compact design.

[0008] For a stable structure, the rear wall has a beveled wall section at the end, extending at least over part of the height of the rear wall. The beveled wall section can optionally extend substantially at right angles to the rear wall. The lateral wall section can be firmly connected to an angled support section of the support.

[0009] Preferably, the second vertical wall section extends at least over part of the height of the floor, in particular completely, and can optionally be firmly connected to an angled section of the support.

[0010] A solid connection between the rear wall and the support can be achieved, for example, by clinching, riveting, welding, mechanical fasteners such as screws, or by other means. The connection between the support and the rear wall in this area achieves high rigidity. For a compact design, the rotating part can be held between the horizontal fold and the step, with the rotating part being located at least partially in its longitudinal extension within the enclosed volume between the horizontal fold and the step on the rear wall.

[0011] To ensure good support of the adjusting element, it can comprise a plate-shaped section that is movable along a sliding surface of the support or a sliding surface on a support body arranged on the support. Thus, a horizontal force can be transmitted via the plate-shaped section and the sliding surface.

[0012] In a preferred embodiment, the step on the bent metal sheet is designed as a groove into which the rear edge of the base is inserted. The step forms the upper section and a second vertical wall section of the groove, with the base resting against at least one section. At the vertical section of the step, it is possible to firmly connect the rear end of the base to the rear wall. A firm connection can be created, for example, by screwing or mechanically clamping. By further bending the metal sheet to form a groove, the rear edge of the base is enclosed in a U-shape, at least over part of the length of the rear wall. By means of the enclosure or, in particular, by means of a firm, direct connection between the rear wall and base, deflection of the base is prevented or minimized.

[0013] For particularly easy adjustment, the rotating part can be accessible from the front and also from the back via an opening in the rear wall. This allows the installer to decide whether the rotating part is to be adjusted using a tool from the front of the rear wall or from the back of the rear wall. Preferably, a tool insert in the rotating part is accessible from both sides and designed, for example, as a tool channel.

[0014] To reinforce the rear wall, the support is preferably made of a bent metal sheet or comprises a section of a bent metal sheet. The support can then preferably be in positive contact with the rear wall to support it. The support can have a stepped contour adapted to the contour of the rear wall, which in the area of ​​the step fits snugly against the rear wall. Optionally, the upper bevel can also be supported by the support.

[0015] In a preferred embodiment, the support is firmly connected to a second vertical wall section of the rear wall, which is formed on the step, and to a lateral, beveled wall section of the rear wall. The respective fixed connection can be established, for example, by clinching, riveting, welding, screwing, or in another way. The fixed connections can be established using the same means or methods on both sections, or they can be different. The connection between the support and various sections of the rear wall at different levels achieves particularly high rigidity.

[0016] In a further embodiment, the support comprises a plastic body having a part fixed to the support and an integrally formed movable part as an adjusting element. In this embodiment, the adjusting element is preferably connected to the fixed part via a flexible web, in particular two parallel flexible webs. This allows the adjustment device to be manufactured with only a few components. A further advantage is that the webs are essentially only flexible in the vertical direction and are very rigid in the lateral and extension directions, so that no rattling noises are generated by moving components.

[0017] The rotating part preferably comprises an eccentric, a worm, or an involute. The rotating part is preferably rotatably mounted on a bearing and can adjust the adjusting element via the eccentric, the worm, or the involute. The eccentric or the involute can have adjustment surfaces, allowing for stepped adjustment.

[0018] For a stable fixation of the rear wall to a side frame, the support can have a lateral bracket that is attached to one of the side frames and preferably engages in the side frame.

[0019] The invention will be explained in more detail below using several exemplary embodiments with reference to the accompanying drawings. They show:

[0034] A drawer 1 comprises a base 2, a front panel 5, and two side frames 4 that connect the front panel 5 to a rear wall 3. The drawer 1 is provided with a pull-out guide with a stationary guide rail 6 and a movable runner rail 7, on which the drawer 1 is held. Optionally, a pull-out extension center rail can be provided between the stationary guide rail 6 and the runner rail 7.

[0035] Figure 2A shows the rear wall 3 in detail. The rear wall 3 is made of a bent metal sheet, in particular a steel sheet, and comprises an upper horizontal fold 31 and a first vertical wall section 30, on the underside of which an angled step 32 is formed. The step 32 is formed at least by an upper fold 320 and a second vertical wall section 300. Furthermore, the step 32 forms part of a groove 33, wherein the groove bottom is offset relative to the first vertical wall section 30. The groove 33 comprises a lower web 34, which, in the assembled position, engages under an edge of the plate-shaped base 2. The edge of the base 2 can be inserted into the groove 33.

[0036] On opposite sides of the rear wall 3, a support 8 of an adjustment device for adjusting the inclination of the drawer 1 is provided. An angled bracket 9 is provided on the support 8, which is fixed to and engages with a side frame 4.

[0037] As shown in Figure 3, the adjustment device comprises the support 8, which has a support plate 10. A support body 14 is arranged on the support 8. The support 8 is made of a metal sheet. The support body 14 can be made of plastic or another material. The support plate 10 comprises a third vertical wall section 100 with an opening 19, which rests against the first vertical wall section 30 of the rear wall. The support plate 10 is provided on its upper side, at least in some regions, with a bevel 11, which is inserted under the horizontal bevel 31 of the rear wall 3. On the underside of the support plate 10, a step 12 with a fourth vertical wall section 13 is formed. The fourth vertical wall section 13 preferably rests against the second vertical wall section 300 at the step 32 of the rear wall 3, so that the rear wall 3 is reinforced by the support plate 10 in the region of the latter.The fourth vertical wall section 13 of the step 12 is firmly connected to the second vertical wall section 300, which reinforces the groove bottom of the groove 33. The support body 14 is fixed to the support plate 10 and forms a pivot bearing for a rotating part 20, which serves to drive an adjusting element 15. The adjusting element 15 is made of a metal sheet and comprises an opening 17 through which the rotating part 20 passes. Two bent tabs 18 are arranged on opposite sides of the opening 17, between which the rotating part 20 is held. The adjusting element 15 comprises a lower edge, which is designed as an adjusting foot 16 and is supported on an upper side of the guide rail 7. Optionally, a further component can be fixed to the adjusting foot 16, which engages with the guide rail 7.

[0038] An adjustment device is provided on the rear wall 3 at each of the opposite end regions, wherein openings 36 are formed on the rear wall 3 in the region of the first vertical wall section 30, which are aligned with the opening 19 and which serve for the engagement of a tool for rotating the rotating part 20.

[0039] A laterally beveled wall section 35 of the rear wall is firmly connected to an angled support section 91 on the boom 9 of the support 8.

[0040] In Figures 4A and 4B, the adjustment device of Figure 3 is shown in a first position. The rotating part 20 comprises a cylindrical section 21, which is held in the pivot bearing of the support body 14. Furthermore, the rotating part 20 comprises an involute 23 on a disc-shaped body, which rests on both the top and bottom sides against the bent tab 18 of the adjusting element 15. By rotating the rotating part 20, the adjusting element 15 can be adjusted relative to the support 8.

[0041] In Figures 5A and 5B, the rotating part 20 is shown in a position adjusted by 180°, and it can be seen that the adjusting element 15 has been adjusted downward, so that when the adjusting foot 16 rests against the guide rail 7, the support 8 and thus the rear wall 3 are raised. By further rotating the rotating part 20, the lowered position shown in Figure 4 can be reached again.

[0042] The rotating part 20 comprises a tool insert 22 which is accessible both from a front side of the rear wall 3 and from a rear side, since the tool insert 22 is designed as a continuous channel and thus a tool can be inserted into the rotating part 20 from both sides.

[0043] Figure 6 shows a modified embodiment of a drawer in which a rear wall 3 extends between two side frames 4. Two adjustment devices are arranged on the rear wall, comprising a support 40 and an adjusting element 50 movable relative to the support 40.

[0044] Figure 7A shows the adjustment device on one side of the drawer in detail. The adjusting element 50 comprises a plurality of projections 51 that engage with a rotating part 60 to enable the adjusting element 50 to be adjusted relative to the support 40. The adjusting element 50 comprises an adjusting foot 54 that is supported on an upper side of the guide rail 7. The adjustment device comprises a support 40 made of sheet metal, which bears against the rear wall 3 in the region of the first vertical wall section 30 and is at least partially adapted to the contour of the rear wall 3, in particular in the region of the step 32, since the support 40 comprises a corresponding step 43 that bears against both the upper side and the vertical sections. A lower vertical wall section 44 of the support 40 bears against the second vertical wall section 300 of the rear wall 3.A plurality of guide tabs 45 are integrally formed on the support 40, which serve to slidably guide the adjusting element 50. The guide tabs 45 can also have a different shape and be designed as a guide section.

[0045] In Figure 7B, the adjustment device is shown in a position when the drawer 1 is raised relative to the guide rail 7. The adjusting foot 54 is supported on the guide rail 7, and by rotating the rotating part 60, the adjusting element 50 is displaced downward to raise the drawer 1. The adjustment range of the adjustment device can be, for example, between 2 mm and 10 mm, in particular 3 mm and 8 mm.

[0046] Figure 8 shows the adjustment device of Figure 7 in detail. The carrier 40 comprises integrally formed guide tabs 45 and two slot-shaped openings 46 which can be used to guide the adjusting element 50. An opening 41, in which the rotating part 60 is rotatably held, is cut out between the guide tabs 45. The rotating part 60 comprises a worm 61 which surrounds a tool insert 62. The tool insert 62 can be accessible from a rear side through an opening 52 in the adjusting element in a middle or upper position of the adjusting element 50 and is also accessible from a front side of the rear wall 3 through the opening 41. The adjusting element 50 comprises a receptacle 56 which is surrounded by a U-shaped contour of the adjusting element 50 and serves to receive the rotating part 60. From this U-shaped contour, wings extend outwards with guide webs 55, which form a sliding section and engage behind the guide tabs 45.The adjusting element 50 further has a step 53, to which the adjusting foot 54 is connected, which in the mounted position is arranged adjacent to the vertical wall section 44 of the support 40.

[0047] Figure 9 shows the support 40 from the opposite side. The support 40 includes a bevel 42 in its upper area, which can optionally be applied to the upper bevel 31 of the rear wall 3. Furthermore, the lateral bracket 9 for fixing to the side frame 4 is formed integrally with the support 40.

[0048] Figure 10 shows the adjusting element 50, which has projections 51 on the side facing the carrier 40, which engage with the worm 61 of the rotating part 60. Furthermore, projections 57 are formed on one wing, which engage in the slot-shaped openings 46 of the carrier 40 to provide guidance in the vertical direction. An angled web 59 is formed on the adjusting element 50 as a stop, which is arranged between the two guide tabs 45. This allows the adjustment path to be limited by the rotating part 60. The web 59 is arranged between two guide tabs 58 of the adjusting element 50, which form a sliding section.

[0049] Figure 11 shows a further embodiment of an adjustment device comprising a support 70 made of sheet metal. The support 70 has a bracket 9 for connection to a side frame 4. An opening 71 for rotatably supporting a rotating part 76 is formed on a plate-shaped section of the support 70. The support 70 is adapted to the contour of the rear wall 3 and has a step 74 and a lower vertical section 75 that can be placed against the step 32 and the second vertical wall section 300 of the rear wall. Two integrally formed tabs 73 are provided on the plate-shaped support 70. These tabs protrude from the support 70 and engage in a part 82 of a plastic body. The plastic body comprises an adjusting element 80 that is movable relative to the part 82, which is firmly held on the support 70. For this purpose, the part 82 is connected to the adjusting element 80 via two flexible webs 83.Optionally, only one web or more than two webs can be provided for the connection. The elongated part 82 and the adjusting element 80 have a step and can rest against the two offset vertical regions on the support 70 and the section 75. An elongated hole 81 is formed on the adjusting element 80, through which the rotating part 76 passes. The rotating part 76 comprises an eccentric 77 and a cylindrical part 78 with a tool insert 79. Upon rotation of the rotating part 76, the adjusting element 80 is guided displaceably on the cylindrical part 78 through the elongated hole 81.

[0050] Figure 12A shows a raised position of the adjustment device, in which an adjusting foot 88 is arranged in a lower position and, in the installed position, is supported on an upper side of the guide rail 7. The webs 83 between the part 82 and the adjusting element 80 are inclined to the horizontal. The rotating part 76 comprises a protruding stop 85, which bears against a projection 86, so that the rotating part 76 can no longer be rotated counterclockwise. If a tool engages the tool insert 79, the rotating part 76 can be rotated clockwise, for example, until the position shown in Figure 12B is reached. By rotating the rotating part 76, the eccentric 77 ensures an adjustment of the adjusting element 80 relative to the carrier 70, and the webs 83 are aligned horizontally. The rotating part 76 can now be rotated further clockwise to lower the drawer 1 relative to the guide rail 7.

[0051] Figure 12C shows the lowered position, in which a bottom side of the adjustable foot 88 is arranged at substantially the same height as the lower edge of the support 70. The webs 83 are arranged inclined to the horizontal, and the rotating part 76 rests against a further projection 87 with the stop 85.

[0052] The carrier 70 has an upper bevel 72 which, as in the previous embodiments, can optionally contact the bevel 31 of the rear wall 3.

[0053] Figure 13 shows a further embodiment of a rear wall 3' which is not made entirely of sheet metal, but only in the two end regions. Two end sections 38 of the rear wall 3' are connected to one another via a wall section 39, which can be made of a different material than the end sections 38. The end sections 38 made of bent sheet metal have an upper horizontal fold 3T and a lower step 32', between which a vertical wall section 30' is formed. Openings are formed in the end section 38 to enable a rotating part 20, 60, 76 to be rotated using a tool. On the underside of the step 32', a vertical wall section 33' is formed, which can optionally also be designed as a groove to engage around an edge of the base 2.

[0054] The embodiments described above can be combined with one another as desired. For example, the rotating part in the individual embodiments can be designed as an eccentric, involute, or worm.
