Description

The present invention relates to a furniture hinge for pivoting

Connecting a first furniture part to a second furniture part, comprising: a first fitting part for fastening to the first furniture part, a second fitting part for fastening to the second furniture part, the second fitting part being pivotably connected to the first fitting part via at least one hinge axis.

Furthermore, the invention relates to an arrangement with a first furniture part, a second furniture part and with a furniture hinge for pivotably connecting the first furniture part to the second furniture part.

Furthermore, the invention relates to furniture with at least one such furniture hinge or with an arrangement of the type mentioned above.

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 fastened to a furniture body or to another movable furniture part by means of a plurality of furniture hinges spaced apart from one another, the problem often arises during assembly that the furniture hinges are in an unstable open position and / or that the relative positions the furniture hinges differ from each other, whereby the assembly of the furniture part on the predetermined by the furniture hinges

Mounting positions is considerably more difficult.

The object of the present invention is to provide a furniture hinge of the type mentioned at the outset while avoiding the above disadvantage.

This is solved according to the invention by the features of patent claim 1.

Further advantageous embodiments of the invention are in the dependent

Claims specified.

According to the invention, it is therefore provided that: the first fitting part has a base plate to be fastened to the first furniture part and a coupling piece which is mounted pivotably about the hinge axis, the coupling piece being releasably connectable to the second fitting part, a first locking device through which the coupling piece is releasably lockable in a predefined pivot position relative to the base plate, - the second fitting part has at least one guide device for guiding the coupling piece, the coupling piece having been pushed or pressed onto the guide device by a second one

Locking device is releasably connectable to the second fitting part, - the first locking device for releasing the predefined pivot position of the coupling piece relative to the base plate can be unlocked by connecting the coupling piece to the second fitting part.

Thus, the first fitting part has a base plate and a movably mounted one

Coupling piece, which is releasably lockable in a predefined pivot position, preferably in a fully open position relative to the base plate, by a first locking device. The coupling piece can also be detachably connected to the second fitting part, the locked coupling piece being able to be pushed on or pushed on relative to a guide device of the second fitting part during assembly of the movable furniture part until the coupling piece is automatically locked to the second fitting part. This locking of the coupling piece with the second fitting part unlocks the first locking device 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 the first fitting part with the locked coupling piece is preassembled on the first furniture part and the second fitting part 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 fitting part fastened to the second furniture part and thereby the first

Locking device to release the movement of the coupling piece is unlocked.

According to one embodiment, it can be provided that the first

Locking device has at least one movable, preferably pivotable, mounted locking part which engages in a locking position in a recess arranged or formed on the first fitting part. The

Bolt part can be biased in the direction of the locking position by an energy store, so that an automatic locking is brought about between the bolt part and the recess. The locking part thus penetrates in a position in which the locking part is aligned with the recess by the force of the

Energy storage automatically into the recess and thereby locks the

Coupling piece in the predefined swivel 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 pivotably connecting the first furniture part to the second furniture part.

According to one exemplary embodiment, it can be provided that two or more furniture hinges are provided for pivotably connecting the first furniture part to the second furniture part, the first fitting parts of the furniture hinges being preassembled on the first furniture part and the second fitting parts of the furniture hinges on the second furniture part, the coupling pieces of the first fitting parts can be locked in each case in the same predefined pivoting position relative to the base plates of the furniture hinges fastened to the first furniture part by the first locking devices. Thus, all coupling pieces of the two or more furniture hinges can be locked in the same predefined pivot position, so that the second fitting parts preassembled on the second furniture part can be connected to one another by pushing or pressing on the coupling pieces of the first fitting parts in the same predetermined joining direction.
