permits an adjustment in the direction of the depth of the furniture as well as in the direction of the door gap although the hinge mounting device is of extremely simple construction for example pedestals 13 on opposite sides of the slide piece 3 project into corresponding clearances or slots 12 in opposite sides of the hinge arm 2 thus providing a fixed guiding of the slide piece 3 in the hinge arm 2 which prevents the slide piece 3 from being twisted during adjustment of the hinge arm 2 in the direction of the depth of the piece of furniture it should be mentioned that only the ends of the mounting plate 1 are provided with guides 9 thus the hinge arm 2 need not be inserted into the mounting plate 1 from the front thereof and over the whole length of the mounting plate 1 but rather it may be positioned onto the mounting plate and anchored thereon by a short movement into the guides 9 this embodiment makes it possible for plural hinge arms 2 to be inserted one after the other into their respective mounting plates 1 when the door is being assembled as tilting of the hinge arm 2 and the mounting plate 1 is virtually impossible after the hinge arm 2 has been adjusted in the direction of the depth of the furniture it is fixedly positioned by means of the mounting screw 14 which abuts against the mounting plate 1 thereafter the adjustment of hinge arm 2 in the direction of the gap between wall 6 and door 7 may be carried out by turning the adjustment screw 15 which fits into a thread in.
