Description

The invention relates to a drawer, collapsible, for almost tool-free assembly, with at least two SeitenWandelementen, a front wall element, a rear wall element, a collapsible floor, an area for guide elements, expandable in height, and in the internal layout according to the preamble of claim 1.

State of the art:

Dismountable drawers have a complex field of application both in the field of kitchen furniture, home furniture, office furniture, and in sales facilities u. like. More. It is known that such drawer can be transported in a disassembled state to save space and are reassembled on site in an advantageous manner, with more or less tool-free can be worked.
It always a solid non-dismountable floor is used, which requires a lot of space during transport depending on the size of the drawer.

The time and complexity of assembly restricts the possibilities for using such systems especially when it is a lavishly designed drawer, which consists of many different items.

Such solutions are inter alia in the DE 29 707 568 . DE 4200581 . DE 8705187 and DE 9001485 described.

Increases in height, additional functions in the internal structure and the divisibility of the drawer bottom into individual identical elements are thus not feasible.

The FR 2 204 957 A5 discloses a collapsible drawer having two side wall panels, front and rear wall panels and a floor, wherein the connection of the side wall panels to the rear and front panels is via bores on the rear panel and through tapped holes on the front wall panel by fasteners.

Task:

The invention has for its object to develop a drawer of the initially named type, which allows for a nearly tool-free assembly simultaneous expandability in height and in the interior layout. Here, the drawer should consist of a few basic profiles and only one, multiply used fastener and a dividable in equal size elements floor. The individual parts should be designed so that an assignment of the components from the right and left as well as from above and below is not necessary. The space required in the disassembled state is as low as possible, and thus transport costs and transport damage can be greatly reduced.

The object of the invention is achieved with the features of the protection claim 1.

The two side wall elements (1), the rear wall element (2) and the front wall element (3) are preferably made of an extruded aluminum hollow profile that is machined after dividing into certain lengths.

The aluminum hollow profile, which is preferably extruded for all wall elements, is provided with two equal recesses (8) on the inner side, which are each arranged at the same distance from the upper edge (10) and from the lower edge (11).

In order to receive the connecting element (4) in the preferably extruded aluminum hollow profile, two cylindrical chambers (6) are each arranged at the same distance from the upper edge (10) and from the lower edge (11).

The cylindrical chambers (6) are slightly larger, so that the connecting element (4) can be inserted without resistance.

The two side wall elements (1) are provided after determining the length on both end faces, each with an equally large fold (9). Thus, each side wall element (1) is equally usable for both sides.

The single floor element (12) is preferably made of an extruded aluminum hollow profile, which has a spring profile edge (13) and a groove profile edge (14).

The spring profile edge (13) of a bottom element (12) engages mechanically, correspondingly in the groove profile edge (14) of the other floor element (12) and forms a locked planar entity.

Thus, any number of floor elements (12) can mechanically add to a surface together and disassemble again.

Before assembly, depending on the width of the drawer, the individual floor elements (12) are mechanically joined together and the resulting surface in one of the recesses (8) inserted correspondingly.

The connection of the side wall elements (1) with the rear wall element (2) and front wall elements (3) via in each case the same connection elements (4).

The connecting element (4) is guided by the counterbore located in the rear wall element (2) and by the cylindrical chambers (6) in the side wall element (1) and connected to the threaded bore located in the front wall element (3).

The connecting element (4) consists of a threaded rod with a machined Senkschraubkopf.

Are again once the same size side wall elements (1), the rear equal wall element (2) and the front equal wall element (3) without a bottom surface consisting of individual floor elements (12), connected to the connecting element (4) to form a frame structure , this can be placed on the drawer with bottom surface, consisting of individual floor elements (12).

To connect the two frame structures, the connecting strips (15) are inserted in the following sequence in the two superimposed recesses (8) on all four inner sides of the drawer.

First, the superimposed side wall elements (1) are connected on both sides with a connecting strip (15) in the length of the clear inner dimension of the drawer depth. Thereafter, the two superimposed rear wall elements (2) and the two superimposed front wall elements (3) each having a connecting strip (15) in the length of the clear drawer width minus the projections (19) of the connecting strips (15) of the side wall elements (1). This creates a drawer with a higher height.

This superimposing of frame structures can be repeated as often as desired until the desired height of the drawer is reached.

The connecting strip (15) is preferably made of an extruded aluminum hollow profile, which is inserted in the two recesses (8) correspondingly fitting.

After dividing into certain lengths, the connecting strip (15) with central and equidistant mounted holes (16) provided for receiving the transverse division (17) and longitudinal division (18) are determined.

If two or more frame structures are connected to the connecting strips (15), it is possible to place various drawer inserts (20) on the projection (19) of the connecting strip (15) and to displace them either in width or in depth, which are placed underneath Utensils remain stowed clear and access is possible at any time.
