These can comprise an attachable to the body stop or hinge part and a fixable on the movable furniture part hinge part. With the mutually pivotable stop parts furniture parts such as a door or a flap can be moved via a hinged mechanism provided with the hinge.

In so-called double link or four-joint hinges, for example, two articulated levers or articulated arms are provided on the hinge.

The AT 005 477 U1 concerns a hinge for furniture. The GB 1 484 294 A suggests a snap hinge.

Purpose and advantages of the invention

The object of the present invention is to make the abovementioned arrangements with extended functionality compact. In this case, an optically advantageous appearance of the hinge should be realized.

This object is solved by claim 1. The dependent claims are directed to advantageous variants of the invention.

The invention is based on a hinge for a hinged on a body of a furniture movable furniture part, in particular for a door or flap, wherein the hinge a has attachable to the body first stop member, which is pivotally connected via a hinge mechanism with an attachable to the movable furniture part second stop member, wherein the hinge mechanism mounted on hinge axes articulated lever comprises. One aspect of the invention is that a further pivotally mounted lever is present, which is temporarily engaged in a complete intended pivotal movement of the hinge with a guide portion on the hinge, wherein the further lever acts on a damper assembly of the hinge.

The further lever is pivotally received via a separate axis to the hinge axes. Thus, an adapted to spatial conditions or variable positioning of the other lever can be done. The further lever may be present, for example, on a stop member in the region between two existing hinge axes.

The guide section comprises a guide groove, which is formed tuned for the temporary engagement with an engagement portion of the other lever. For example, a protruding or raised part such. B. engage an engagement nose on the other lever in the guide groove and possibly moved in Einkupplungszustand along the guide groove. Not excluded, but not according to the invention, is a reversal of the form, according to which the guide portion has an engagement portion which engages in the coupling state in a guide groove on the other lever.

The damper assembly of the hinge is used in particular to achieve a damped or braked movement in an end position of the pivoting operation carried out with the hinge in a proper pivoting movement of the hinge. This can be avoided in the mounted on the furniture state of the hinge in particular an undesirable strong slamming of the movable furniture part, in particular an unpleasant Additional noise or damage to the furniture part and the carcass.

The operation of the damper assembly takes place in the interaction of the further lever with the guide portion advantageously always at the same point of the pivotal movement of the furniture part or at an identical pivot position of the hinge on the way to an end position of the pivoting movement possible with the hinge. The interaction of the other lever with the guide portion can be realized very compact or compact. In particular, the further lever and the guide section can be provided in areas which are freely available anyway with known corresponding hinges. These areas are preferably in the interior of the hinge, not or hardly visible from the outside. In this way, in the case of an arrangement according to the invention, a desired appearance or a preferred exterior design can be realized without difficulty.

According to the invention, the further pivotally mounted lever is present,
which is temporarily engaged in a full intended pivotal movement of the hinge with a guide portion on the hinge, wherein the further lever acts on an actuator of the hinge. By an actuator is generally meant an element which converts an input to a different output to produce a desired action or effect. As Aktorprinzipien inductively operating electric motors, hydraulic or pneumatic actuators, cylinders, electrochemical or electro-mechanical actuators, piezo actuators are conceivable.

In particular, an electric motor can be operated or controlled via the interaction of the further lever with the guide section.

In particular, this phase describes a phase before reaching an end point of the pivoting movement, that is to say the point of engagement, up to the associated end point, without reversing the direction of movement. From this end position, reversing the direction of movement, the engagement state is maintained until the corresponding point of engagement is reached and the decoupling or decoupling takes place. Disconnection usually remains until the other endpoint is reached. However, it is not excluded further engagement in the pivoting movement in the other endpoint.

In the case mounted on the furniture, a decoupled or uncoupled situation of the further lever and the guide section is again achieved during a return movement of the hinge, for example when the movable furniture part is opened relative to the carcass. In this case, the damper assembly and the actuator is brought back into an initial state according to the action of the lever. In the subsequent renewed closing movement, the damper arrangement or the actuator of the hinge is then operated again.

It is further proposed that the further lever is adapted to act on a portion of a component which is present on the attachable to the body first stop member. Thus, the damper or an actuator can be accommodated on the attached to the body abutment part, which is advantageous for structural reasons or for reasons of space usually.
