Description

[0001] drawer

[0002] The present invention relates to a drawer with a front panel, a base, two side frames and a rear wall connecting the side frames, each of which is connected to one of the side frames via a connector, wherein the rear wall has a front side directed in the direction of the side frames, wherein the front side projects upwards beyond the side frame and from which a holding means of the connector projects laterally and above the side frames in the upper projecting area of ​​the front side, wherein at least one rail is arranged on the holding means above the side frame.

[0003] DE 10 2012 102 029 A1 discloses a drawer with a connecting element for attaching a railing to a rear panel. The connecting element comprises a first section for attaching to the railing and a second section that can be locked into a recess in a web of the rear panel. This allows for easy installation of the railing, but the holding forces of the connection are limited due to the thin webs on the connecting element. Furthermore, the connecting element is positioned in the visible area, thus failing to meet the requirements for a minimalist design.

[0004] A stable structure is required, especially for drawers where a frame wall is to be fixed via the railing, as shown in DE 20 2018 105 329 U1.

[0005] It is therefore an object of the present invention to provide a drawer in which a railing is fixed in a stable manner over a side frame using simple means.

[0006] This object is achieved with a drawer having the features of claim 1.

[0007] In the drawer according to the invention, the rear wall is connected to one of the side frames on opposite sides via a connector, wherein the rear wall in each case has an end face directed in the direction of the side frames. The end face projects upwards above the side frame and a holding means of the connector projects laterally and above the side frames from the upper projecting area of ​​the end face, wherein at least one rail is arranged on the holding means above the side frame. The holding means has a fastening section directed in the direction of the front panel, which engages in a cavity in the rail and is fixed in the cavity to secure the rail. In this way, a stable fixation between the side frame and the rail is created via the connector, so that their position is firmly predetermined.

[0008] Preferably, the fastening section is fixed to a plug inserted into the railing. At least a portion of the retaining means can also be inserted into the railing to provide stable support for the railing. The plug can be covered by the railing and the front of the rear wall, so that the plug, which is at least partially arranged in the railing, is not visible from the outside, thus optimizing the visual appearance.

[0009] In a preferred embodiment, the retaining means or the fastening section on the retaining means is secured to the plug by a rigid or clamped connection. Flexible spring bars or other locking means can be provided to prevent corrosion. For a clamped connection, a clamping element, in particular a wedge, can ensure a force-fitting fixation.

[0010] The plug inserted into the railing preferably comprises a receptacle with a flexible spring bar, in which a portion of the retaining means is accommodated. As a result, the retaining means and the portion are concealed within the plug, so that the fastening means on the drawer are not visible or only very slightly visible from the outside.

[0011] To ensure stability, the retaining element comprises a U-shaped bend that engages around a web on the rear wall. The retaining element, to which the plug is attached, is formed on one leg of the U-shaped bend facing the front of the drawer. This results in a compact design, and the railing can be supported laterally on the two legs of the U-shaped bend.

[0012] The plug is preferably arranged with more than 80% of its volume within the railing, in particular more than 90% or even completely within the railing. The railing encloses a hollow space, this hollow space being defined by the length of the railing, which extends to one end face of the railing, even if individual sections of the hollow space are provided with a recess. Such recesses can be provided, for example, on the underside of the hollow space or on a side wall in order to facilitate the assembly of the railing with the plug to the holding means. The plug and the railing preferably have a downward-facing opening in the region of the fastening section for inserting the fastening section. The railing can have a substantially cuboid-shaped hollow chamber, although other geometries of the hollow chamber are also possible, for example circular, oval or polygonal.

[0013] In a further embodiment, the railing has a downward-facing receiving channel for accommodating at least one decorative element, for example, a decorative panel, which is arranged between the side frame and the railing. A locking element for securing the decorative element can be arranged on the plug. The locking element can have a release mechanism for removing the decorative element, for example, a release lever for releasing the fixation. The locking element can be designed as a spring clip or locking pin and can be actuated, for example, using a tool.

[0014] The railing is preferably held to the front panel by a plug element inserted into the railing. A holding element, for example a projection, onto which the plug element is plugged can be fixed to the rear of the front panel. For this purpose, the plug element can have a downwardly open receptacle, which is then pushed onto the holding section from above. A U-shaped bend can be formed between the fastening section and the holding section, and the side frame is fixed to the forward-facing leg of the fastening section for a stable structure. The holding means for fixing the railing are preferably formed integrally with the holding section. The holding section of the connector can have a first vertical section that rests against the rear wall and a second vertical section that is arranged on a rear side of the base of the drawer.Due to a stepped structure of the holding section, the connector can be supported on the floor and rear wall.

[0015] In a further embodiment, an adjustment device is fixed to the connector, by means of which a support element can be adjusted vertically for inclination adjustment. This allows the stable construction of the connector to be used for inclination adjustment, for example, with an eccentric, a worm gear, or an involute.

[0016] The railing is preferably made of a bent metal sheet, but can also be made of other materials, such as a plastic profile.

[0017] The embodiments of the invention are discussed with reference to the following figures.

[0025] Figures 8A to 8C show several views of a modified plug for fixing the railing.

[0026] A drawer 1 comprises a plate-shaped base 2, a rear wall 3, and a front panel 4. The rear wall 3 and the front panel 4 are each connected to each other via side frames 5. The drawer 1 is provided with a high front panel 4, which is fixed to the rear wall 3 on opposite sides via a railing 6 with a connector 10.

[0027] As can be seen from the exploded views in Figures 2A and 2B, two connectors 10 are located on the rear wall 3. The connectors 10 can be mirror-symmetrical. The connectors 10 serve to secure the rear wall 3 to the side frames 5.

[0028] Each connector 10 comprises a holding section 11, which at least partially abuts the rear wall 3, and a fastening section 12 protruding from the rear wall 3 and fixed to a side frame 5. The fastening section 12 preferably engages the side frame 5 and is fixed there via fastening means, in particular a locking mechanism. The fastening section 12 can at least partially abut the inner side of a wall of the side frame 5 and support it.

[0029] Each connector 10 is made of a bent metal sheet, in particular a steel sheet. The rear wall 3 is also made of a metal sheet, and the rear wall 3 can also be firmly connected to the connector 10 at fastening points, for example by clinching, riveting, welding, screwing, or other fastening means.

[0030] The holding section 11 comprises a first vertical section, which is connected in the upper region to an angled web 13 and in the lower region via a step 15 to a second vertical section 16, which is arranged offset horizontally to the rear. In the mounted position, the second vertical section 16 rests against a rear side of the base 2.

[0031] The rear wall 3 has an upper bevel 31 in its upper region, which can be angular or U-shaped and is connected via a vertical section to a step 33 that projects towards the rear and is connected to a second vertical section 34. In the assembled position, the step 33 can rest on the floor 2, and the vertical section 34 is arranged at the rear of the floor 2. The second vertical section 34 can also have a lower horizontal web 35, so that the floor 2 is enclosed by the step 33, the second vertical section 34 and the horizontal web 35 at the rear.

[0032] The rear wall 3 further comprises, on opposite lateral end faces, an angled web 32 on which a plurality of openings can be formed. The connector 10 is adapted to the contour of the rear wall 3 in the region of the holding section 11, with the step 15 and the offset vertical section 16. The holding section 11 is connected to the fastening section 12, which is fixed to the side frame 5, via a U-shaped bend 14. The U-shaped bend 14 forms a vertically extending channel into which the laterally angled web 32 of the rear wall 3 is inserted. Above the bend 14, an angled web 20 is formed on the holding section 11. The angled web 20 is provided with openings that align with openings in the angled web 32 and can be used for fastening means. The holding section 11 is provided with an angled web 21 on the opposite side for reinforcement.

[0033] Furthermore, an adjustment device is connected to the holding section 11, comprising a housing 9 on which a support element 8 is arranged so as to be adjustable in the vertical direction. The support element 8 is driven via a rotating part 7, which can be designed as an eccentric, involute, or worm and is rotatably mounted on the housing 9 and an opening 17 of the connector 10. For securing the housing 9, holding means 18 in the form of retaining tabs are integrally formed on the connector 10. Optionally, other fastening means for securing the housing 9 can also be provided.

[0034] Figures 3A and 3B show the two connectors 10 on opposite sides of the rear wall 3 in the assembled position. It can be seen that the angled web 32 of the rear wall engages the U-shaped bend 14, and the fastening section 12, which is formed on the longer leg of the U-shaped bend 14, protrudes toward a front side. The housing 9 is at least partially arranged in the space enclosed by the vertical section 30, the bevel 31, and the lateral webs 32.

[0035] The connector 10 is shown in detail in Figures 4A to 4C, with Figure 4A showing the left connector 10 and Figures 4B and 4C showing the right connector 10, which is mirror-symmetrical to the left connector 10 with respect to a central plane. The connector 10, each manufactured from sheet metal by punching and bending, comprises the holding section 11, which is formed integrally with the fastening section 12 via the U-shaped bend 14, with a vertical channel being provided in the U-shaped bend 14. A holding means 19 on the connector 10 comprises a fastening section 36 for fixing the railing 6. The holding means 19 is formed integrally with the holding section 11 and comprises a further U-shaped bend, with a leg of the bend facing away from the rear wall 3 and pointing forward serving to fix the railing 6.

[0036] Figures 5A to 5C show the railing 6, which is made of a bent metal sheet and has a cuboid-shaped hollow chamber 61. Other geometries for the hollow chamber 61 can also be produced, with the railing 6 being U-shaped on the underside, thus forming a downwardly open receiving channel 62, into which an upper edge of a wall element or other decorative element can optionally be inserted. However, the railing 6 can also be rectangular or square in cross-section, i.e., without the lower receptacle.

[0037] The railing 6 is fixed to the front panel 4 via a plug element 22 that can be secured to a holder 23. The dowel-shaped holder 23 can be fixed to a rear side of the front panel 4, for example, by screwing, so that the plug element 22 can be pushed onto the holder 23 from above. The railing 6 has a lower recess on the front end so that the plug element 22 can be pushed onto the holder 23.

[0038] At the rear, the railing 6 is secured by a plug 40, which, in the mounted position, is arranged entirely within the railing 6. The railing 6 has a lateral and lower recess 60 in the rear area, so that part of the plug 40 is accessible. The plug 40 has a front insertion part 42 and, in the area of ​​the recess 60, a receptacle 43 with a spring bar 44. Furthermore, a spring clip 41 is provided on the plug 40.

[0039] The assembly of the railing 6 in the rear area is shown in detail in Figures 6A to 6E.

[0040] Figures 6A and 6E show the drawer 1 in which the railing 6 is mounted above the side frame 5. For this purpose, the plug 40 is inserted into the hollow chamber 61 of the railing 6 until an end wall at the recess 60 abuts a stop on the plug 40. The plug 40 can be fixed to the railing 6, for example, by a stamping process. By fixing the plug 40 to the railing 6, the parts are permanently connected to one another. The unit comprising the plug 40 and the railing 6 can then be pushed downwards onto the holding means 19 or swung open to fix the railing 6 to the holding means 19 of the connector 10.

[0041] Figures 6C to 6E show the assembled position of the railing 6. The plug 40 is arranged completely within the railing 6 with respect to the envelope surface of the railing 6, and the holding means 19 engages the plug 40 and the railing 6. When plugged onto the holding means 19, a section of the holding means 19 is inserted into the receptacle 43 of the plug 40, and the spring bar 44 is locked to the holding means 19. The holding means 19 has an opening in the region of the U-shaped bend, into which the spring bar 44 engages with one end. Instead of the opening, a profiling or other locking element can also be provided. As a result, the railing 6 with the plug 40 is secured against being lifted by the holding means 19.

[0042] In the lateral direction, the railing 6 is supported on the web 20 of the connector 10. In the opposite direction, the retaining means 19 prevents movement.

[0043] Figures 7A to 7C show the plug 40 in detail. The plug 40 comprises a front insertion part 42 and a rear portion with the receptacle 43 and the spring bar 44. The spring clip 41 surrounds an outer portion and is secured to an upper side of the plug 40 via an angled end 45 and protrudes downward from the retaining portion with a curved portion 46.

[0044] Figures 8A to 8C show a modified embodiment of a plug 40', which, like the previous embodiment, comprises an insertion part 42 and a holding section with a receptacle 43 and the spring bar 44. Instead of the spring clip 41, a locking pin 50 is provided, which can be inserted into a receptacle of the plug 40'. The locking pin 50 comprises a bar 51 with upper ribs 52 or other profiling, which can be locked to a locking bar 49 to be held in a predetermined insertion position.

[0045] The railing 6 can be designed in various ways. The railing 6 can be designed as a narrow bar, as described, so that a clearly open area exists between the top of the frame and the railing 6. However, the railing 6 can also close off or reduce the open area, so that it is designed considerably wider. The railing 6 can consist of several surface elements or just a single surface element in order to close off or reduce the open area. In a special design, the railing 6 can also rest on the top of the frame.
