DRAWER WITH ONE BASE PLATE, TWO SIDE PANELS, ONE BACK PANEL AND ONE PANEL

Description

[0001] The invention relates to a drawer with a base plate, two side walls, a rear wall and a panel according to the preamble of claim 1.

[0002] In most common drawers, all of these components—the base plate, the two side panels, the back panel, and the front panel—are made of wood or at least similar materials. All of these components are joined together using state-of-the-art technology to form a single, solid piece, a drawer. It is also known to fit these components with coordinated hardware, thus assembling the drawer.

[0003] The document DE 39 42 897 A1 describes a drawer with a base plate, two side walls, a rear wall, and a panel, the panel being detachably attached to the side walls. The side walls and the rear wall have an internal groove in the area of ​​the lower edge for receiving the base plate. The panel on the rear side carries two panel fittings that can be connected to side wall fittings inserted into the facing end faces of the side walls. The ends of the side walls facing the rear wall carry fittings that are provided with locking hooks and can be locked into locking receptacles in the rear wall. A disadvantage appears to be that no connection between components made of different materials is provided, and the connection between the panel and the side walls must be made manually, which increases production costs.

[0004] From the document EP 2 580 987 A1 a drawer is known in which all components are made of metal.

[0005] EP 1 157 636 A1 describes a fastening arrangement, particularly for drawer side panels, comprising several fastening elements connectable to a rail of a pull-out guide, which have receptacles for connecting cover elements. According to the invention, the cover elements are held to the fastening elements in a modular manner and have fastening means for attaching connecting elements. Here, too, the attachment of the cover appears to be complex.

[0006] The object of the invention is to develop a drawer which is easy to assemble with its components, but wherein the panel can be subsequently connected to a prefabricated unit and then detached again.

[0007] This problem is solved with the features of claim 1.

[0008] According to the invention, the wooden panel has two panel fitting parts on the back, which have receiving fitting parts of the panel fitting part inserted into the facing end faces of the side walls, wherein the receiving fitting part is designed to automatically pull the panel towards the end faces of the side walls when the horizontal bolt is inserted into the inlet and to lock it thereto under tension and is further designed to eject the horizontal bolt from the inlet after the locking is triggered and to lock the receiving fitting part in this position, wherein the panel is detached from the side walls.

[0009] In order for the side walls to be able to easily accommodate the receiving fittings required for assembling the prefabricated unit, an advantageous further development of the drawer provides that the receiving fittings are inserted between the two side parts on the end face facing the panel and can be connected to the panel fittings on the back of the panel, and wherein the inner side part of the double-layered side wall has a support or a receiving groove for the base plate.

[0010] According to a further embodiment of the drawer, the side wall fitting part connected to the end of the side walls and to the rear wall protrudes with locking hooks on the inside of the inner side parts and can be connected and locked to locking receptacles of the rear wall.

[0011] According to a further embodiment of the drawer, the side walls have recesses in the area of ​​the outside through which access to the receiving fitting part built into the side wall is possible and that the recesses can be covered with plates.

[0012] In a further design of the drawer, the mounting fitting of the side wall has two adjusting screws with which the panel on the drawer can be adjusted in height and side.

[0013] A further design of the drawer provides that the side walls have grooves in the top for dividing sections, which are aligned parallel to the drawer panel.

[0014] According to a further design of the drawer, it is provided that, independently of the side wall, the drawer is provided with guide rails that are connected to the base plate of the drawer.

[0015] The drawer according to the invention is explained in more detail using exemplary embodiments in the accompanying drawings.

[0016] The Fig. 1 and 2 show a drawer consisting of a base plate 10, two side walls 11 and 12, and a rear wall 13 made of sheet metal. These sheet metal components can be pre-assembled as a prefabricated unit using fittings and then fitted with a wooden panel 15, which can be subsequently attached to and removed from the prefabricated sheet metal unit consisting of base plate 10, two side walls 11 and 12, and the rear wall 13. Fig. 1 and 2 the finished drawer in two perspective positions seen on the back wall 13 and the panel 15.

[0017] How Fig. 2 shows, the upper side of the side walls 11 and 12 can be provided with receiving grooves which accommodate a dividing section 15.1 which is aligned parallel to the front panel of the drawer.

[0018] The Fig. 3shows the sheet metal parts for the base plate 10, the two side walls 11 and 12 as well as the rear wall 13, whereby the side wall 12 and the rear wall 13 have folds in the area of ​​their lower edge, which form a support or a receiving groove 17 or 18 for the base plate 10.

[0019] In Fig. 4 A cover 15 is assigned to the prefabricated sheet metal unit, which closes the open front of the prefabricated sheet metal unit. This cover 15 carries two cover fittings 20 on its rear side, which can be connected to and detached from the receiving fittings 21 built into the front of the side walls 11 and 12. In addition, the Fig. 4 a side wall fitting part 25 attached to the end of the side walls 11 and 12, which connects the rear wall 13 to the side wall 12.

[0020] The Figs. 5 and 6show that the side walls 11 and 12 consist of two side parts 11.1 and 11.2, which are beveled and carry the receiving fitting part 21 on the front side for receiving the panel fitting part 20 on the back of the panel 15. The outer side part 11.1 is provided with a recess 23, which can be covered by a plate 22.
