DESCRIPTION:

BRIEF SUMMARY
The invention relates to a furniture hinge having a hinge arm which is adjustably situated on a mounting plate and, at two bearing locations spaced along its length, is held on the mounting plate either directly or indirectly via an intermediate part. The hinge arm or intermediate part can be engaged with the mounting plate in a formfitting manner at one bearing location and is held by resilient arresting connection at a the other bearing location.
A furniture hinge of this type is known (German Gebrauchsmuster 89 07 480). To obtain an arresting connection between the intermediate part and the mounting plate, the longitudinal sides of the intermediate part, which part is U-shaped in cross section, are provided with arresting tongues integral with the intermediate part and extending to the rear end of the hinge arm. The resilient tongues are U-shaped in this region and an inner leg of each projects through a slit-like opening in a front plate of the intermediate part. The free legs of the tongues project into an interior compartment of the intermediate part and, upon being placed on the mounting plate, are guided inwards and into an undercut arresting recess of the mounting plate by cooperation with inclined surfaces of the mounting plate. To release the locking mechanism, the tongues are pressed together manually and removed from the region of the undercut surfaces.
This construction of the furniture hinge is expensive to manufacture since the tongues which act as arresting means, and the operating portions of the mounting plate cooperating therewith, must be produced to close tolerances.
It is an object of the invention to design a furniture hinge of the type mentioned at the outset in such a manner that it is structurally simple, economical to manufacture and has little susceptibility to trouble during operation.
In the hinge of the invention, only one resilient tongue is provided and is arranged at the end of the hinge arm facing away from the hinge axis. This tongue can be swung into a released position by pressing two lateral operating bars inwards. Close tolerances are not required during production of the lateral operating bars. In the hinge of the invention, the overall structure is simpler.
An exemplary embodiment of the furniture hinge according to the invention is illustrated in the drawings and is described below. In the drawings:
FIG. 1 is a side view, partly in section, of a hinge arm with an intermediate part secured thereto, an associated mounting plate, also being illustrated,
FIG. 2 shows the components of FIG. 1 in assembled condition,
FIG. 3 is a side view of the intermediate part shown in FIGS. 1 and 2,
FIG. 4 is a view in the direction of the arrow IV in FIG. 3,
FIG. 5 is a section along the line V--V of FIG. 4.
FIG. 6 is a view similar to that of FIG. 3 of a second embodiment of the hinge arm, and
FIG. 7 is a view similar to that of FIG. 4 of the second embodiment of the hinge arm.
The hinge arm 1 is connected, via lateral hinge bars 2,3, with a non-illustrated hinge component which is attached to a lid, a door or the like.
In the illustrated exemplary embodiment, the hinge arm 1 is connected with an intermediate part 6 by means of a fastening screw 4 and an adjusting screw 5. The intermediate part 6 has a bolt 7 at the side facing the hinge axis of the hinge. The bolt 7 is fixed in the lateral legs 8 of the intermediate part which is U-shaped in cross section.
The mounting plate 9, which is fixed to a furniture wall 11 via fastening screws 10, has a bearing recess 12 at the side facing the hinge axis of the furniture hinge. As seen from FIG. 2, the bolt 7 is engaged in the bearing recess 12 in a formfitting manner so that the bearing recess 12 and the bolt 7 define a first bearing location
At the front side facing away from the hinge axis of the furniture hinge, the intermediate part 6 is equipped with a resilient tongue 13 which, in the exemplary embodiment, is integral with the intermediate part 6 and has an arresting groove 14. An arresting ledge 15 of the mounting plate 9 catche
