  • Patent number: 4685751
    Abstract: A furniture drawer with a front cover that is adjustable and fixable in at least one direction includes connecting hardware having at least two forked gripping members disposed a distance apart. The jaws of the gripping members define an insertion slot and can be pressed together by a closing element. An enlarged head of a web member is engaged by the gripping member. The head is narrower than maximum clearance between the jaws when the head member is inserted into the gripping member. Inclined surfaces are disposed in the region of the said jaws immediately behind the insertion slot and immediately behind the head member and cooperate with projections that abut the inclined surfaces. When the jaws are drawn together, clearances are present between the web member and the outer ends of the jaws, as well as between the head member and the interior regions of the jaws. A first fitting piece outside the drawer front is mounted on the back side of the front cover.
