Patent Application
20120286637
The invention relates to a drawer which can be dismounted or taken apart for nearly no-tools assembly, having at least two sidewall elements, a front wall element, a rear wall element, a bottom which can be dismounted, an area for guide elements, extendibility in height and in its internal layout, according to the introductory portion of patent claim 1.
Break-down drawers or drawers which can be dismounted have multiple fields of application both for kitchen, house, and office furniture, and in sales facilities and the like. It is known that these kinds of drawers when disassembled require little space for transport and can be advantageously assembled on site wherein more or less no-tools assembly work is provided. What is always used is a firm, non-sectional bottom requiring much space for transport, depending on the drawer's size.
The time required and the complexity in assembly confine the options in using these kinds of systems particularly if the drawer is complicated in design and consists of very many different components.
These kinds of solutions are described among others in DE 29 707 568, DE 4200581, DE 8705187 and DE 9001485.
Extensions in height, additional functions in the internal structure, and sectioning the drawer bottom to obtain single, identical elements cannot be realized therewith.
The invention relates to the object to develop a drawer of the type indicated initially which, given a nearly no-tools assembly, concurrently allows extensions in height and in the internal layout. The drawer is adapted to consist of a small number of basic profiles and only one type of multiple-use connecting element, and a bottom that can be dismounted to equal-sized elements. The components are provided to be structured such that they do not require classification to right and left, or top and bottom. That the space required when disassembled be as small as possible and thus transport costs and transport damage can be greatly reduced.
The object according to the invention is solved by the features of claim 1.
The two sidewall elements (1), the rear wall element (2) and the front wall element (3) preferably consist of an extruded hollow aluminum profile which is machined after being divided to specific lengths.
The hollow aluminum profile which is preferably extruded for all of the wall elements is provided on its inner face with a pair of identical recesses (8) located at the same distances from the upper edge (10) and the lower edge (11).
Two cylindrical chambers (6) are equally spaced from the upper edge (10) and from the lower edge (11) to receive the connecting element (4) in the preferably extruded hollow aluminum profile.
The cylindrical chambers (6) are marginally larger for the connecting element (4) to be pushed in resistance-free.
After specifying the length the two sidewall elements (1) are provided with equal-sized rabbets (9) at their two end faces. Thus each of the sidewall elements (1) can be equally employed for both sides.
The single bottom elements (12) preferably consist of an extruded hollow aluminum profile comprising a key profile edge (13) and a groove profile edge (14).
The key profile edge (13) of a bottom element (12) mechanically engages correspondingly in the groove profile edge (14) of the other of the bottom elements (12), forming a locked surface area.
This allows to mechanically join any desired number of bottom elements (12) to form a surface, and to break it down again.
Prior to assembly or mounting the bottom element pieces (12) are joined mechanically to obtain the desired drawer width and the combined surface thus formed is correspondingly inserted into one of the recesses (8).
The sidewall elements (1) are joined to the rear wall element (2) and the front wall elements (3) by way of the same connecting elements (4).
The connecting element (4) is guided through the counterbore (5) on the outside face in the rear wall element (2) and through the cylindrical chambers (6) in the sidewall element (1), and connected with the threaded bore (7) located in the front wall element (3).
The connecting element (4) consists of a threaded rod with an integral, countersunk screw head.
When the equal-sized side wall elements (1), the rear equal-sized wall element (2) and the front equal-sized wall element (3) with no bottom surface consisting of bottom element pieces (12), are once again connected with the connecting element (4) to form a frame structure, the same can be placed onto the drawer with a bottom surface consisting of single bottom elements (12).
To connect the two frame structures the connecting battens (15) are inserted into the two superposed recesses (8) at all of the four inner faces of the drawer in the following sequence.
First, the superposed side wall elements (1) are connected on their two sides with a connecting batten (15) of the length of the clear internal dimension of the drawer depth. Then the two superposed rear wall elements (2) and the two superposed front wall elements (3) are each connected with one connecting batten (15) of the length of the clear drawer width less the protrusions (19) of the connecting battens (15) of the side wall elements (1). In this way a drawer of a larger height is created.
Such superposed connecting of frames may be repeated as many times as desired until the intended drawer height is obtained.
The connecting batten (15) preferably consists of an extruded hollow aluminum profile which is correspondingly snugly fitted into the two recesses (8).
After sectioning to specific lengths the connecting batten (15) is provided with centered, evenly spaced bores (16) adapted to receive the transverse partition (17) and lengthwise partition (18).
When two or more frames are connected with the connecting battens (15) then various drawer inserts (20) can be placed on the protrusion (19) of the connecting batten (15) and they can be displaced either over the width or the depth, the objects stowed therein remain neatly grouped and access is possible at any time.
The invention will be explained in detail by way of the drawings by the following exemplary embodiments.
The drawings show in detail what follows:
The solution according to the invention will be exemplarily illustrated by way of assembling a drawer.
First the front wall element (3) of the drawer is placed onto a flat surface with the outside surface downwards.
Depending on the width of the drawer the bottom element pieces (12) are joined mechanically and the bottom surface thus created is correspondingly inserted into the recess (8) of the front wall element (3).
Both of the side wall elements (1) are now correspondingly placed on the front wall element (3) by one of their end-face rabbets (9) and with the recess (8) correspondingly placed onto the bottom surface consisting of multiple bottom elements (12).
Thereafter the rear wall element (2) is correspondingly placed in the other two end-face rabbets (9) of the side wall elements (1) and the recess (8) of the rear wall element (3).
Thereafter four connecting elements (4) are guided through the counterbores (5) on the outside in the rear wall element (2) and through the cylindrical chambers (6) in the two side wall elements (1) and fixedly connected with the threaded bores (7) located in the front wall element (3).
Thus the drawer is completely assembled in its lowest height.
Depending on which of different underfloor guide elements are used, different bores and or recesses are required on the bottom face of the drawer.
The solution according to the invention will be illustrated exemplarily by the extendibility of a drawer in height and in its internal layout.
Higher drawers can be assembled according to the same principle as it was shown for drawers in example 1.
To this end another frame structure without a bottom surface is placed on the assembled drawer consisting of two side wall elements (1), a rear wall element (2), a front wall element (3), a bottom surface consisting of multiple bottom elements (12) and connected by connecting elements (4).
To connect the two frame structures the connecting battens (15) are inserted into the two superposed recesses (8) on all of the four inner faces of the drawer in the following sequence.
First, the superposed side wall elements (1) are connected on their two sides with a connecting batten (15) of the length of the clear internal dimension of the drawer depth. Thereafter the two superposed rear wall elements (2) and the two superposed front wall elements (3) are connected with one connecting batten (15) each in the length of the clear drawer width less the protrusions (19) of the connecting batten (15) of the side wall elements (1).
Such superposed connecting of frames may be repeated as many times as desired until the intended drawer height is obtained.
When two or more frames are connected with the connecting battens (15) then various drawer inserts (20) can be placed on the protrusion (19) of the connecting battens (15) and they can be displaced either over the width or the depth, the objects beneath remain neatly stowed and access is possible at any time.
