Similar constructions are also shown in DE 39 13 319 A1, in DE 40 18 235 A1 and in DE 41 03 923 A1.

Movable furniture parts are usually pivotally mounted on two or more furniture hinges on a fixed furniture body or on another movable furniture part. In particular, when using a high furniture part, which is to be attached via a plurality of spaced apart furniture hinges on a furniture body or on another movable furniture part, often results in the assembly the problem that the furniture hinges are in a labile open position and / or that the relative positions the furniture hinges differ, whereby the mounting of the furniture part is considerably more difficult at the predetermined by the furniture hinges mounting positions.

Object of the present invention is to provide a furniture hinge of the type mentioned above while avoiding the above drawback.

This is achieved by the features of claim 1. Further advantageous embodiments of the invention are specified in the dependent claims.

According to the invention, it is thus provided that:

a first locking device is provided, by means of which the coupling piece can be releasably locked in a predefined pivoting position relative to the base plate, and in that

- The first locking device for releasing the predefined pivot position of the coupling piece relative to the base plate by connecting the coupling piece with the second fitting part is unlocked.

Thus, the first fitting part on a base plate and a movably mounted coupling piece which is releasably locked in a predefined pivot position, preferably in a full open position relative to the base plate by a first locking device. The coupling piece is also releasably connectable to the second fitting part, wherein the locked coupling piece in the assembly of the movable furniture part relative to a guide device of the second Fitting part can be pushed or pushed until an automatic locking of the coupling piece with the second fitting part. By this locking of the coupling piece with the second fitting part, the first locking device is unlocked again, so that the coupling piece (and thus the furniture hinge) is released again for a pivoting movement in normal operation.

In this way, the assembly of the second furniture part is considerably simplified, since first the first fitting part with the locked coupling piece on the first furniture part and the second fitting part is pre-assembled on the second furniture part. The second furniture part is then pressed or pushed onto the locked coupling piece of the first fitting part until the coupling piece of the first fitting part is locked by the second locking device with the second furniture part attached to the second furniture part while the first locking device is released to release the movement of the coupling piece.

According to one embodiment, it can be provided that the first locking device has at least one movable, preferably pivotable, mounted latch part, which engages in a locking position in a recess arranged or formed on the first fitting part. The latch member may be biased in the direction of the locking position by a force accumulator, so that an automatic locking between the latch member and the recess is brought about. The latch member thus penetrates in a position in which the latch member is aligned with the recess, by the force of the energy storage automatically in the recess and thereby locks the coupling piece in the predefined pivot position.

The arrangement according to the invention comprises a first furniture part, a second furniture part and at least one furniture hinge of the type described for the pivotable connection of the first furniture part to the second furniture part.
