Description

[0001] drawer

[0002] The present invention relates to a drawer with a front panel, a rear wall and two side frames between the front panel and the rear wall, on which a base is held, wherein at least one side frame has an inner wall and an outer wall, each of which protrudes downwards from the base.

[0003] WO 2019 / 118997 A1 discloses a double-walled drawer side panel in which a rounded portion is provided on one outer wall to prevent damage to the base when a drawer with such a drawer side panel is placed on a surface. When a loaded drawer is placed on a surface, comparatively high forces act on the outer wall with the rounded portion. This can lead to undesirable deformation or damage to the outer wall, as it is made of a thin material and the weight forces act on the outer wall with a large leverage.

[0004] It is therefore an object of the present invention to provide a drawer in which protection against damage to a support is possible even with high weight loads.

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

[0006] The drawer according to the invention comprises a front panel, a rear wall, and two side frames between the front panel and rear wall, to which a base is held, wherein at least one side frame has an inner wall and an outer wall, each of which protrudes downwards from the base. In a rear region of the drawer, a portion of the inner wall projects beyond the outer wall when the base is horizontally aligned, and a rear portion at the end of the inner wall has a rounded support contour. The rounded support contour forms a section that runs around at least one axis, wherein the axis is arranged substantially perpendicular to a drawer inner surface of the inner wall. As a result, the drawer is supported by the inner wall, offset inward from the outer wall, so that the weight loads of the drawer can be carried further inside on the rounded support contour.This allows comparatively high forces to be dissipated, with the base preferably resting directly on the inner wall at a support section, allowing forces to be transferred from the rounded support contour to the base via the section of the inner wall located below the base. The axis of the receiving contour does not have to be the same for all sections of the receiving contour, but can be arranged at different positions depending on the section of the receiving contour.

[0007] When the front panel is lifted, the drawer preferably rolls along the support contour at the rear end of the side frame. A support contour is preferably arranged on the inner wall of each of the oppositely arranged side frames, so that when the drawer is lifted, it rolls over the two support contours, which form a pivot axis for the drawer. The support contour serves to support the drawer when it is pivoted from a position with an approximately horizontal base to a raised position. The rounded support contour thus prevents damage to the support surface, e.g., a table.

[0008] The outer wall preferably has a recess or relief contour at a rear lower end. The relief contour can be formed, for example, by a cutout in the area of ​​the rounded support contour. The relief contour can, for example, be a diagonally cut surface or an arcuate contour on the underside of the outer wall to prevent the outer wall from coming into contact with the support surface, even when the drawer is tilted.

[0009] In a first variant, the support contour is formed by an embossing on the inner wall. The embossing can be designed as a nub or bead and forms a round support surface without sharp edges. Alternatively, the support contour can also be formed on a rounded edge on the inner wall according to a second variant.

[0010] In a further embodiment, the support contour is arranged on a separate support which is fastened in the rear area of ​​the inner wall. The support is preferably supported on the underside of the inner wall, which also forms the support section for the base. The support is preferably made of plastic and thus forms a softer support surface for the support contour than the inner wall material. To ensure stable support of the drawer, the inner wall can have a downward-facing web arranged beneath the base, on which a curved section is formed directed towards the outer wall, on which the support contour is formed. A weight load can then be transferred from the base into the curved section via the downward-facing web, resulting in optimal leverage, since the point of force introduction is directly at the curved support contour.

[0011] The inner wall preferably has a groove into which an edge of the base is inserted. The base can rest on and be supported by a lower groove wall, which forms the support section. For a stable design of the side frame, the outer wall can be supported by the inner wall in the area of ​​the base, for example, by one or more embossed portions of the inner wall. This allows for better support of transverse forces. The support contour is preferably supported by the web or by the lower groove wall of the groove on the underside of the base.

[0012] To prevent damage to the support surface, the support contour can have a radius between 2 mm and 40 mm, in particular between 4 mm and 30 mm. The inner wall can be made of a metal sheet, although other materials can optionally be used. If a metal sheet is used, it preferably has a thickness between 0.5 mm and 1 mm.

[0013] The invention will be explained in more detail below using several exemplary embodiments with reference to the accompanying drawings. They show:

[0015] Figure 2 is a sectional view through a side frame of the drawer of Figure 1;

[0016] Figures 3A and 3B show two views of a modified embodiment;

[0017] Figure 4 is a perspective view of a side frame of the

[0018] Drawer of a third embodiment; Figure 5 is an exploded view of the side frame of Figure 4;

[0019] Figure 6 is a detailed view of the inner wall of the side frame of Figure 4, and

[0020] Figures 7A and 7B show a rear view of an inner wall and a separate support surface according to Figure 4.

[0021] A drawer 1 comprises a front panel 2, a rear wall 3, and two side frames 4 between the front panel 2 and the rear wall 3. In the assembled position, the drawer 1 is held on a pull-out guide on a furniture body and can be removed from the pull-out guide. The pull-out guide can, for example, be designed as a concealed pull-out guide, in which the rails of the pull-out guide are arranged beneath a base 5 of the drawer 1.

[0022] In order to be able to place the drawer 1 on a support surface 10 before mounting it on the pull-out guides or after dismantling it from the pull-out guides without scratching or damaging the surface, the drawer 1 has a support contour 43 in the rear area, as shown in Figure 1B. Each side frame 4 comprises an outer wall 41 and an inner wall 40, between which a hollow space is formed. On the inner wall 40, in the rear area, adjacent to the rear wall 3, a support contour 43 is formed on a section 44 bent towards the outer wall 41. This rounded support contour 43 has no sharp edge and thus prevents damage to the support surface 10 when the drawer 1 is placed on the support contour 43. The drawer 1 can roll along the two support contours 43 of the side frames 4 when the front panel 2 is lifted from the support surface 10.The support contour 43 remains the only contact point between the drawer 1 and the support surface 10 over an angle a, i.e., when the bottom of the drawer 1 is horizontally aligned, up to an angle a of 15° or preferably up to 45°. A section 46 is formed on the support contour, which extends at least around an axis A.

[0023] Figure 2 shows a section through a side frame 4. It can be seen that a cavity 6 is formed between the inner wall 40 and the outer wall 41 above a base 5. The inner wall 40 has a groove 7, advantageously U-shaped, to accommodate an edge of the base 5. In the region of the groove 7, the inner wall 40 is provided with profiles 8, for example projections, on which the smoothly downwardly extending outer wall 41 is supported. In the upper region of the side frame 4, the inner wall 40 has an edge 15 that engages in a receptacle of an upper section 14 of the outer wall 41. The inner wall 40 and the outer wall 41 are fixed to one another in the upper region, preferably via mechanical locking or clamping devices. Optionally, the inner wall 40 and the outer wall 41 can also be formed integrally with one another.

[0024] The inner wall 40 has a downwardly directed web 42, which is arranged below the base 5 and which extends from the lower groove wall 47. At a lower end of the downwardly directed web 42, a section 44 is formed which is bent towards the outer wall 41 and on which the support contour 43 is provided. The support contour 43 is designed here as an embossed feature, for example as a knob or bead, which projects downwards and on which the drawer 1 can be supported on a support surface 10. The support contour 43 on the inner wall 40 is arranged lower than the lowermost end of the outer wall 41, and the height difference h can be, for example, between 1 mm and 10 mm, in particular 2 mm to 5 mm.

[0025] Figures 3A and 3B show a modified embodiment of a drawer 1 in which a rounded support contour 43' is formed on the inner wall 40 adjacent to the rear wall 3 in order to prevent damage to a support surface 10 when the drawer 1 is disassembled and is to be placed thereon. As can be seen from the detailed view of Figure 3B, the support contour 43' is located on the inner wall 40, which projects downwards beyond the outer wall 41, with a section 46' being provided which runs at least around an axis A. The support contour 43' is formed by a rounded cut edge which rests on the support surface 10. The radius of the cut edge can, for example, be in a range between 2 mm and 40 mm. The support contour 43' can also be designed as another arcuate contour.The outer wall 41 is provided in the rear area with a recess 50 formed by a free cut, and a corner section is removed, which is provided between the rear edge of the rear wall 3 and a lower end of the outer wall 41. This prevents contact of the outer wall 41 in the event that the drawer 1 is placed obliquely on the support surface 10, i.e., when the rear end of the side frame 4 is arranged higher than the front end of the side frame 4. Furthermore, the free cut prevents the corner section from protruding beyond the radius or the curved contour of the support contour 43'.

[0026] Figure 4 shows the side frame 4 without the other components of the drawer 1. It can be seen that several recesses with claws 9 are provided on the groove 7 of the inner wall 40 on a lower groove wall 47, which claws can be driven into the bottom 5 to secure the bottom 5. Furthermore, at the rear end of the side frame 4, a support element 11 is provided between the inner wall 40 and the outer wall 41, which is fixed via a tab 16 as a fastening means. In the front area of ​​the side frame 4, a recess is provided, behind which a fastening device 12 for securing the front panel 2 is mounted.

[0027] The exploded view of Figure 5 shows that the fastening device 12 for fixing the front panel 2 is provided within the cavity 6 between the inner wall 40 and the outer wall 41. In the rear area, a further fastening device 13 for fixing the rear wall 3 is arranged in the cavity 6 of the side frame 4. The support element 11 is essentially block-shaped and is covered on the upper side by the lower groove wall of the groove 7, on the inside by the downwardly projecting web 42, and on the outside by the outer wall 41.

[0028] Figure 6 shows the inner wall 40 of the side frame 4 and the support element 11 in detail. On the inner wall 40, in the rear area, on the downwardly projecting web 42, a tab 16 is formed which is pressed inwards and projects into a receptacle 17 on the support element 11. On the support element 11, the support contour 43" is formed with a section 46" which runs around an axis A. The support element 11 is advantageously made of plastic and can thus prevent damage to a support surface 10. By fixing the position of the support element 11 to the lower groove wall of the groove 7 and to the downwardly projecting web 42, forces can be transferred from the support contour 43" to the lower groove wall or the downwardly projecting web 42 if necessary.

[0029] Figures 7A and 7B show the assembly of the embodiment of Figures 4 to 6. The support element 11 is inserted into an angular receptacle on an underside of the lower groove wall 47 of the groove 7 and is fixed on the inside by a tab on the downwardly projecting web 42. The support contour 43" is formed on the support element 11 and can support the drawer.
