DESCRIPTION:
BRIEF SUMMARY
This invention relates to a drawer provided with guide means for opening and retracting the drawer between an open and closed position.
In such drawers, the drawer rails are preferably formed integrally with the side members and a rear wall of the drawer and a drawer bottom is secured to or supported on the side members. If drawers are juxtaposed or superimposed, the front plate, which constitutes a covering, is not exactly aligned inherently owing to manufacturing tolerances and inaccuracies in the assembly so that means for readjusting must be provided. Deviations in height, in the lateral adjustments and in the inclinations of the front plate may occur in practice and must be compensated if a uniform overall appearance of a finished piece of furniture or of a rack in a store is to be ensured.
Known adjusting means often permit a compensation only of a part of said faults from one location.
For an adjustment in height it is known that those legs of the retaining angle members which contact the side member can be secured to the side members by means of eccentrics and that the desired adjustment in height can be effected by the adjustment of said eccentrics. From AT-B 382,504 it is known that a retaining angle member which is secured to the side member can be adjusted in height on the front plate by means of a vertical adjusting screw and that additional retaining screws extending into slots may be used to secure the associated leg of the retaining angle member to the front plate.
In connection with eccentrics used for an adjustment, it is known that the side members may be double-walled and the eccentric may be accommodated in the cavity of the side member and an arrangement in which the means for fixing the carrying angle member of the front plate extend also into that cavity. In that case an expensive side member is required, which has a side opening that can be closed and which requires a relatively large space.
From DE-A1 37 11 756 it is known that carrying members extending over a major part of the height of the front plate can be attached to the front plate and inserted into slots of the side member. A relative adjustment in height may be effected by means of clamp screws. The inclination can only be adjusted by separate means.
From DE-A1 34 12 981 it is known to provide an upright angle member, which is connected to the front plate and extends over a major part of the height of said front plate, and to connect that angle member by resilient arms, which extend downwardly from the top end, and by sheet metal driving screws to a supporting structure, which is connected to the drawer bottom so that the front plate is laterally adjustable although that adjustment consists of a slightly pivotal adjustment about the upper fixing points of the arms. A similar design is known from DE-A1 34 23 925, where it is additionally possible to effect by means of eccentrics and slots a vertical adjustment of the arms, which are pivoted in that case, on the carrying angle members of the front plate.
In other designs, an adjustment of the inclination of the front plate has been permitted by means of a retaining angle member, which is adapted to be secured to the side member and has an upwardly protruding leg, which is directed toward the front plate and is pivoted about a transverse axis by means of a screw to a holder which is secured to the front plate. That design can be adopted only for side members which merely retain a bottom but do not constitute side walls.
DE-A1 34 23 732 discloses a design for effecting a lateral adjustment and an adjustment in height of the front plate. Cooperating wedge surfaces are provided on fixtures, which are separately to be mounted on the front plate and the side members, and the adjustments can be effected along said wedge surfaces. The cooperating fixtures can be fixed by fixing screws.
All known drawers which are of the kind described first hereinbefore and provided with means for adjusting the front plate have basic disadvantages. As has been mentioned, most designs permit only a
