DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a cassette for the construction of a drawer cabinet, the cassette being of the sort that accommodates a drawer and comprises on one hand a rectangular frontal frame from which four walls extend, viz. a bottom wall, two side walls and an upper wall, and on the other hand a rear wall to which said walls are connected, and which frontal frame has substantially vertically positioned flanges in connection with said walls, the drawer in addition to a frontal frame comprising a bottom part, two side parts and a rear part the height of which is greater than the height of the side parts so as to secure that the upper portion of the rear part engages behind the upper flange of the frontal frame and retains the drawer in its position maximally pulled-out from the cassette.
PRIOR ART
A cassette for a drawer cabinet of the sort generally described above is previously known from DE-A-3 905 843. In its basic embodiment, the individual cassette is provided with four male-like members on its underside, in the form of hook-shaped plates or sheet portions intended to be inserted and locked in cooperating holes in the upper side of a subjacent cassette. The cassettes are commercially available in different embodiments, in particular in embodiments with different heights, thereby enabling the user to erect drawer cabinets adapted to individual needs in a quick and flexible way. In the known cassette for drawer cabinets, the drawer is normally arranged to be guided by two guide rails which are placed on both sides of the drawer adjacent to on one hand each side wall and on the other hand to the bottom wall. According to this embodiment, the drawer is retained in its position within the cassette by two projecting members which are formed on the underside of the bottom part of the drawer, in the vicinity of the frontal part of the drawer, in order to be locked behind a lower part of the frontal frame of the cassette as long as the drawer rests upon the cooperating guide rails. Only when lifting the frontal end of the drawer, so that the projecting members pass clear of the lower part of the frontal frame, the drawer can be pulled out in a direction out of the cassette. In its maximally pulled-out position, the drawer is retained in the cassette by an upper edge portion of the rear part of the drawer that engages behind an upper part comprised in the frontal frame of the cassette. For a complete removal of the drawer from the cassette, the frontal portion of the drawer is turned in an upward direction when the drawer is in the region of its maximally pulled-out position.
Further, FIG. 19 to 21 in DE-A-3 905 843 illustrate a special embodiment according to which an individual selected cassette may be supplemented by a special kit including rolls in order to simplify the pulling out and the pushing in of the drawer relative to the cassette. This kit comprises on one hand two analogous, although mirror-inverted runway tracks which are mountable in the space between an individual side wall of the cassette and a fixed guide rail located at a distance from the inside of said wall, and on the other hand an angle-shaped corner shoe which on its outside carries a rotatable pulley or roller and which is intended to be placed on the outside of each rear corner of the drawer. More precisely, the corner shoe is formed in such a way that it may be applied on a rear corner of the drawer while the drawer is in the cassette, viz. in a half pulled out position, the shoe being held in its position after application of a screw which is insertable from the inside via a hole in a side piece of the drawer. The fact that the drawer is still in the cassette when the roller-bearing corner shoe is fastened on the drawer is an absolute condition for this construction at all being capable of being used, since the roller after having been mounted will protrude to a certain degree from the adjacent side part of the drawer; a fact making it impossible for the roller to pass past the frontal fr
