Description

Technical Field

[0001] The present invention relates to a drawer comprising a front panel, a bottom panel, two side frames and a rear wall connecting the side frames, each of the rear walls being connected to one of the side frames via a connector, wherein the rear wall includes an end face facing the side frame, wherein the end face extends upward beyond the side frame, and a retaining device of the connector projects laterally from an upper projection of the end face and over the side frame, wherein at least one rail is arranged on the retaining device over the side frame. Background Technology

[0002] DE102012102029A1 discloses a drawer having a connecting element for securing a railing to a rear wall. The connecting element includes a first section for securing to the railing and a second section that can snap into a recess in a tab on the rear wall. This makes the railing easy to install; however, the retaining force of the connector is limited due to the thin tab on the connecting element. Furthermore, the connecting element is arranged in a visible area, thus failing to meet the requirements of a minimalist design.

[0003] For drawers whose frame walls are secured by railings, a stable structure is particularly needed, as shown in DE202018105329U1. Summary of the Invention

[0004] Therefore, the object of the present invention is to provide a drawer in which the railings are securely fixed to the side frame using a simple device.

[0005] This problem is solved by a drawer having the features of claim 1.

[0006] In the drawer according to the invention, a rear wall is connected to one of the side frames on opposite sides by connectors, wherein the rear wall includes an end face facing the side frame. The end face protrudes above the side frame, and a retaining device of the connector extends laterally from an upper protrusion of the end face and over the side frame, wherein at least one rail is arranged above the side frame to the retaining device. The retaining device includes a fastening section facing the front panel, which engages in and is secured in a cavity within the rail to hold the rail in place. This establishes a stable connection between the side frame and the rail via the connectors, thereby firmly defining their position.

[0007] Preferably, the fastening section is fixed to a stop inserted into the railing. In this case, at least a portion of the retaining device can also be inserted into the railing to stably support it. The stop can be concealed by the front of the railing and the rear wall, making the stop, at least partially disposed within the railing, invisible from the outside and optimizing the visual appearance.

[0008] In a preferred embodiment, the retaining device or a fastening section on the retaining device locks or clamps with the stop. A flexible spring tab or other locking mechanism can be used for locking. For clamping, clamping elements (especially wedges) can be used to achieve force-fit fixation.

[0009] The stop inserted into the railing preferably includes a receiving portion with a flexible spring tab, in which a partial retaining device is received. Thus, the retaining device is arranged in a partially concealed manner within the stop, making the fastening device on the drawer invisible from the outside, or only visible within a very limited area.

[0010] To ensure stability in this embodiment, the retaining device includes a U-shaped bend that engages around a tab on the rear wall. A retaining device for fixing the stop is formed on a leg of the U-shaped bend facing the front of the drawer. This creates a compact structure, and the railing can be laterally supported by the two legs of the U-shaped bend.

[0011] The stop is preferably arranged such that more than 80% of its volume is located within the railing, particularly more than 90% or even entirely within the railing. The railing surrounds a cavity defined by the length of the railing extending to its end face, even if various sections of the cavity are provided with recesses. For example, such recesses may be provided on the bottom or sidewall of the cavity to facilitate the installation of the railing with the stop to the retaining device. The stop and the railing preferably include downward openings in the region of the fastening section for insertion into the fastening section. The railing may include a generally rectangular hollow cavity, although other geometries of the hollow cavity are also possible, such as circular, elliptical, or polygonal.

[0012] In another embodiment, the railing includes a downward receiving channel for receiving at least one decorative element, such as a decorative panel, disposed between the side frame and the railing. Here, a fixing element may be disposed on a stop to secure the decorative element. The fixing element may include a release mechanism for removing the decorative element, such as a release lever for releasing the fixing element. The fixing element may be formed as a spring clip or a snap-fit ​​pin and may be actuated, for example, using a tool.

[0013] The railing is preferably secured to the front panel by a stop element inserted into the railing. A retaining element, such as a protrusion, can be secured to the rear of the front panel, to which the stop element snaps. For this purpose, the stop element includes a downwardly opening receiving portion, which is then slidable from above onto the retaining section. A U-shaped bend can be formed between the fastening section and the retaining section, and a side frame is secured to the forward leg of the fastening section to ensure structural stability. The retaining device for securing the railing is preferably integrally formed with the retaining section. In this case, the retaining portion of the connector includes a first vertical section abutting against the rear wall and a second vertical section arranged to abut against the rear side of the drawer bottom. Through the stepped construction of the retaining section, the connector can be supported against the base plate and the rear wall.

[0014] In another embodiment, an adjustment device is fixed to the connector, through which the support element is vertically adjustable to achieve tilt adjustment. This allows for a stable structure of the connector for continuous tilt adjustment, such as using an eccentric wheel, worm gear, or involute structure.

[0015] The railings are preferably made of bent metal sheets, but can also be made of other materials, such as plastic profiles. Attached Figure Description

[0025] Drawer 1 includes a plate-shaped base plate 2, a rear wall 3, and a front panel 4. Each of the rear wall 3 and the front panel 4 is connected to each other by a side frame 5. Drawer 1 is provided with a high front panel 4, which is fixed to the rear wall 3 on the opposite side by a rail 6 and a connector 10.

[0026] from Figure 2A and Figure 2B As can be seen from the exploded view, there are two connectors 10 on the rear wall 3. The connectors 10 can be formed in a mirror-symmetric manner. The connectors 10 are used to fix the rear wall 3 to the side frame 5.

[0027] Each connector 10 includes a retaining section 11 and a fastening section 12. The retaining section 11 abuts against the rear wall 3 at least in certain areas, and the fastening section 12 protrudes from the rear wall 3 and is secured to the side frame 5. The fastening section 12 preferably engages with the side frame 5 and is secured there by fastening devices, particularly snap-fit ​​mechanisms. The fastening section 12 may at least partially abut against and support the inner surface of the wall of the side frame 5.

[0028] Each connector 10 is made of bent metal plate, particularly steel plate. The rear wall 3 is also made of metal plate, and the rear wall 3 can be securely attached to the connector 10 at fastening points, for example by riveting, welding, threaded connection or other fastening methods.

[0029] The retaining section 11 includes a first vertical section that connects at its upper end to a bent tab 13 and at its lower end to a second vertical section 16 via a step 15, the second vertical section being arranged rearwardly offset in the horizontal direction. In the installed position, the second vertical section 16 abuts against the rear side of the base plate 2.

[0030] The rear wall 3 has an upper bend 31 in its upper region, which may be angular or U-shaped, and has a connection to a step 33 via a vertical section. The step 33 projects rearward and has a connection to a second vertical section 34. In the installation position, the step 33 can rest on the base plate 2, and the vertical section 34 is arranged at the rear of the base plate 2. The second vertical section 34 may further include a lower horizontal tab 35, such that the base plate 2 is surrounded at the rear by the step 33, the second vertical section 34, and the horizontal tab 35.

[0031] The rear wall 3 also includes bent tabs 32 at opposite lateral ends, in which multiple openings can be formed.

[0032] In the region of the retaining section 11, the connector 10 is adapted to the contour of the rear wall 3 via a step 15 and an offset vertical section 16. The retaining 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 channel extending in the vertical direction into which the laterally inclined tab 32 of the rear wall 3 is inserted. Above the bend 14, a bent tab 20 is formed on the retaining section 11, which has an opening that aligns with the opening on the bent tab 32 and can be used for fastening. The retaining section 11 has bent tabs 21 on opposite sides for reinforcement.

[0033] Furthermore, at the retaining section 11, an adjustment device with a housing 9 is connected, on which a support element 8 is adjustable in the vertical direction. The support element 8 can be driven by a rotating component 7, which can be designed as an eccentric, involute, or worm gear, and is rotatably supported on the opening 17 of the housing 9 and the connector 10. For securing the housing 9, a retaining device 18 in the shape of a retaining protrusion is integrally formed on the connector 10. Alternatively, other fastening devices for securing the housing 9 may also be provided.

[0034] Figure 3A and Figure 3B Two connectors 10 are shown in their mounting position, located on opposite sides of the rear wall 3. It can be seen that the bent tab 32 of the rear wall engages with the U-shaped bend 14, and a fastening section 12 formed on the longer leg of the U-shaped bend 14 protrudes forward. The housing 9 is at least partially arranged within the space enclosed by the vertical section 30, the bend 31, and the lateral tab 32.

[0035] Figures 4A to 4C The connector 10 is shown in detail, wherein Figure 4A The left connector 10 is shown. Figure 4B and Figure 4C The right connector 10 is shown, mirror-symmetrical to the left connector 10 with respect to its center plane. Each connector 10, made of sheet metal by stamping and bending, includes a retaining section 11 integrally formed with a fastening section 12 via a U-shaped bend 14, wherein a vertical channel is provided in the U-shaped bend 14. A retaining device 19 on the connector 10 includes a fastening section 36 for securing the railing 6. The retaining device 19 is integrally formed with the retaining section 11 and includes an additional U-shaped bend, wherein the forward-facing leg of the bend faces away from the rear wall 3 for securing the railing 6.

[0036] Figures 5A to 5CA railing 6 made of bent metal sheet is shown, comprising a rectangular hollow cavity 61. Other geometries of the hollow cavity 61 are also possible, wherein the railing 6 is U-shaped on the bottom side, thus forming a downwardly opening receiving channel 62 into which the upper edge of a wall element or another decorative element may optionally be inserted. The railing 6 may also have a rectangular or square cross-section, i.e., without a lower receiving portion.

[0037] The railing 6 is secured to the front panel 4 by a stop 22, which is also secured to a bracket 23. The pin-shaped bracket 23 can be secured to the rear side of the front panel 4, for example, by screws, allowing the stop 22 to slide from above onto the bracket 23. The railing 6 includes a recess at its front end, allowing the stop 22 to be pushed onto the bracket 23.

[0038] At the rear, the railing 6 is secured by a stop 40, which is fully disposed within the railing 6 in the installed position. The railing 6 includes lateral and lower recesses 60 in the rear region, making a portion of the stop 40 accessible. The stop 40 includes a front insertion portion 42 and a receiving portion 43 with a spring tab 44 in the region of the recess 60. Furthermore, a spring clip 41 is provided on the stop 40.

[0039] For details on the installation of railing 6 in the rear area, please refer to... Figures 6A to 6E .

[0040] Figure 6A and 6E Drawer 1 is shown, with railing 6 mounted above side frame 5. For this purpose, a stop 40 is inserted into the hollow cavity 61 of railing 6 until the front of the drawer abuts against the stop 40. Stop 40 can be fixed to railing 6, for example, by a stamping process. By fixing stop 40 to railing 6, these components are permanently connected to each other. The assembly consisting of stop 40 and railing 6 can then be pushed downwards or screwed into retaining device 19 of connector 10 to secure railing 6 to retaining device 19 of connector 10.

[0041] Figures 6C to 6E The installation position of the railing 6 is shown. The stop 40 is completely disposed within the railing 6 relative to its enclosing surface, and the retaining device 19 engages with both the stop 40 and the railing 6. In this configuration, when the retaining device 19 is engaged, a portion of the retaining device 19 is inserted into the receiving portion 43 of the stop 40, and the spring tab 44 is snapped into the retaining device 19. The retaining device 19 includes an opening in the U-shaped bend area into which one end of the spring tab 44 engages, although a profile or another locking element could also be provided instead of the opening. This secures the railing 6 with the stop 40, preventing it from lifting off the retaining device 19.

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

[0043] Figures 7A to 7C The stop 40 is shown in detail. The stop 40 includes a front insertion portion 42 and a rear section having a receiving portion 43 and a spring tab 44. A spring clip 41 surrounds the outside and is secured to the top side of the stop 40 by a bent end 45, wherein the bent portion 46 protrudes downward from the retaining portion.

[0044] Figures 8A to 8C An improved embodiment of the stop 40' is shown. Similar to the previous embodiment, the stop 40' includes an insertion portion 42 and a retaining section having a receiving portion 43 and a spring tab 44. A snap-fit ​​pin 50 can be provided instead of the spring clip 41, which can be inserted into the receiving portion of the stop 40'. The snap-fit ​​pin 50 includes a tab 51 with an upper rib 52 or another profile capable of engaging with the snap-fit ​​tab 49 to retain it in a predetermined insertion position.

[0045] The railing 6 can be designed in various structures. The railing 6 can be designed as a narrow bar as described, resulting in a noticeable opening area between the top of the frame and the railing 6. However, the railing 6 can also close or reduce the opening area, making it significantly wider. The railing 6 can be composed of multiple surface elements or only a single surface element to close or reduce the opening area. In a specific embodiment, the railing 6 can also rest on top of the frame.
