BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to a furniture hinge having a hinge arm and a housing which may be installed in a recess of a door or the like. The hinge arm is pivotally connected to the housing by means of at least one link bar and is secured to a quick-mounting plate via a fastening screw. The quick-mounting plate, in turn, is releasably connected to a support which can be fixed at the furniture side. The quick-mounting plate is provided with a spring-loaded pawl having a retaining lip which engages a projection of the support from below.
Furniture hinges of the above type are also referred to as quick-mounting hinges and are known in various forms.
A characteristic and common feature of all these furniture hinges is that the hinge arm can be adjustably secured to a quick-mounting plate which can be fixed to the support with virtually no tools. Conversely, the quick-mounting plate can again be released from the support by operating the pawl.
In practice, it is not readily possible to prevent unintentional separation of the quickmounting plate and support under certain circumstances. On the other hand, it is frequently difficult to operate the pawl when separation is desired since it is located relatively close to the inner surface of the furniture.
OBJECTS AND SUMMARY OF THE INVENTION
It is accordingly an object of the present invention to provide a furniture hinge of the preceding character which, with a most simple design, increases the reliability of this type of furniture hinge in daily use and allows intentional separation of the quick-mounting plate and support without particular difficulty.
According to the invention, the stated object is achieved in that the hinge arm is provided with a cover which overlies at least the fastening screw and, in addition, either completely covers the pawl of the quick-mounting plate or has a blocking device which is disposed in the rotational path of the pawl.
By employing a simple cover which can be manufactured economically, a furniture hinge of the foregoing type is significantly improved. On the one hand, the cover overlies the fastening screw for the hinge arm and quick-mounting plate while, on the other hand, the same cover prevents unintentional operation of the pawl which allows the quick-mounting plate to be released from the support. Thus, unintentional and undesired separation of the quick-mounting plate and support is prevented in an effective and most simple manner.
In accordance with a favorable embodiment, the cover is rotatably mounted on the pawl in the region opposite the retaining lip and the axis of rotation of the cover is parallel to and spaced from the pivot axis of the pawl. The blocking device here releases the pawl in an angular position of the cover relative to the hinge arm.
The retaining lip of the pawl is disengaged from the overlying projection by the application of tension and, in the preceding embodiment, it is of particular advantage for the cover to constitute an operating element for the pawl. Moreover, neither can mounting be forgotten nor can the cover be lost. Since, especially for furniture which is assembled by the buyer, the sections of the hinge are already secured to the components of the furniture, this makes it unnecessary to supply the cover separately. Furthermore, the cover can be attached during production of the hinge so that the buyer receives a fully installed hinge. The side of the cover which faces the hinge arm can be provided with instructions in the form of letters or symbols.
Advantageously, a stationary abutment is located on the side of the pawl opposite the retaining lip and the corresponding end face of the cover bears against this abutment when the cover is brought into an angular position relative to the hinge arm.
In this manner, the retaining lip is disengaged from the projection upon movement of the cover into an angular position so that no further forces need be applied to separate the quick-mounting plate and support.
