BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention relates to a hinge comprising a hinge arm adjustably held on a mounting plate, a joint adjustment screw or the like and an adjustment device acting in the direction of the depth of a piece of furniture on which the hinge is mounted, the hinge arm being lockable on the mounting plate by means of a resilient snap-in mechanism and held on the mounting plate directly or by means of an intermediate member indirectly at two positions along the length of the hinge arm.
In conventional hinges, the hinge arm is fastened to the mounting plate by means of a clamping screw generally projecting through an oblong hole to permit adjustment of the hinge arm in the direction of the depth of the piece of furniture.
Lately, snap-in connections for fastening the hinge arm to the mounting plate have become known. DE-A-30 26 796 and DE-A-30 39 328, for example, each show a hinge with a hinge arm and a fastening plate, wherein such two parts, which are to be interlocked, snap into each other by inserting the hinge arm into a guide of the fastening plate and by displacing the hinge arm in a longitudinal direction. A similar way of anchoring a hinge arm to a mounting plate is shown in DE-A-24 60 127. DE-A-32 41 284 shows a hinge in which the hinge arm is insertable into lateral guides of a mounting plate and clampable to the mounting plate by means of an eccentric.
The afore-described ways of anchoring a hinge arm to a mounting plate have the advantage that the hinge arm can be quickly fastened to the mounting plate during assembling operations and, further, that no tools are required for mounting. Such advantage is not unimportant because when the hinge arms are mounted, a door to which the hinge arm is fastened must be held. If, for example, the door is held with one hand and the hinge arm to be mounted is held with the other hand, a second person is often required to fasten the clamping screw with a screw driver, if the hinge arm is locked by means of a clamping screw.
It is a disadvantage of hinges in which the hinge arm or the intermediate member is insertable into the mounting plate from the front that they easily cant.
This occurs in particular in the case of high doors which carry many hinges. In most cases, the hinge arm has to be displaced almost over the entire length of the mounting plate.
SUMMARY OF THE INVENTION
It is the object of the invention to provide an improved hinge with resilient snap-in locking, wherein depth adjustment of the hinge arm is possible when the hinge arm has already been mounted on the mounting plate, wherein the hinge is of simple construction and wherein the hinge arm is easily mountable onto the mounting plate and releasable therefrom.
According to the invention, this object is achieved by providing that the hinge arm or an intermediate member is engageable with the mounting plate at a first bearing and is pivotable about such first bearing, while the hinge arm intermediate member has at least one resilient catch projection is provided forming a second bearing so that the hinge arm and the mounting plate are held together at this point by means of a snap connection.
An embodiment of the invention provides that the hinge arm is pivotally engaged by means of a joint adjustment screw to that end of the mounting plate which is directed toward the hinge link or links of the hinge, such joint adjustment screw together with projections of the mounting plate forming the pivot bearing, and that there is provided on the hinge arm and/or on the mounting plate a holding clamp which is resilient or acted upon by a spring and holds the end of the hinge arm pivotable about the pivot bearing of the hinge arm by engaging in a second holding clamp or in a stop member of the corresponding hinge part.
A holding clamp preferably is held on the hinge arm by means of a clamping screw and has two flanges aligned parallel to the pivot axis of the hinge, one of such flanges engaging in a groove of the mounting plate, and the other of such flanges having a slot or the like
