BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The subject invention relates to a connecting fitting for a detachable connection of two angularly abutting furniture walls, consisting of two each fittings which are mounted on one of the furniture walls, one of which is provided with a spring mounted holding tongue which is mounted transverse to its longitudinal axis and which extends into the other fitting and engages behind a stop protrusion of the corresponding fitting.
Connecting fittings of the type mentioned are known per se.
In a known connecting fitting of the type mentioned the holding tongue is mounted axially stationary in the corresponding fitting. The stop protrusion of the other fitting extends in an oblique position to a stop rib of the holding tongue, thus ensuring that the two furniture walls being connected be pulled solidly towards each other under any circumstances.
Such a structure requires the maintaining of very low tolerances, since otherwise the desired solid connection of the two furniture walls is not achievable.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide an improved connecting fitting in such a manner that a solid pulling together of the furniture walls be connected be made possible even when relative large tolerances are present.
This object of the invention is solved by the connection fitting which includes:
(a) the holding tongue displaceably mounted within the first fitting in the direction of its longitudinal axis and movable by means of a clamping part,
(b) the free end of the holding tongue is shaped as a catch hook and is deflected towards the fitting, and
(c) a stop protrusion of the other fitting is undercut according to the deflection of the catch hook.
The inventive structure does not only offer the advantage that the overcoming of relative large tolerances is made possible, because the holding tongue can be moved over the clamping part in its longitudinal direction, but also permits a comfortable preassembling because due to the deflected catch hook, on the one hand, and the correspondingly undercut stop protrusion, on the other hand, so that the two furniture walls to be connected may be secured by assembling the two fittings at least to such an extent that an accidental release would be no longer possible.
Since normally a plurality of such connecting fittings are used when assembling a complete furniture, the individual furniture walls may at first be preassembled and subsequently the solid connection of the individual furniture walls may be accomplished by actuating the clampping parts of the individual fittings.
The novel features which are considered as characteristic for the invention are set forth in particular in the appended claims. The invention itself, however, both as to its construction and its method of operation, together with additional objects and advantages thereof, will be best understood from the following description of specific embodiments when read in connection with the accompanying drawing.
