Definitions

• the present invention relates to a furniture hinge comprising:
• a first stop member for attachment to a furniture body
• a second stop part for attachment to a movably mounted furniture part, wherein the second stop part is articulated to the first stop part
• At least one helical spring having a direction of action, wherein the furniture hinge is movable by the helical spring from a predetermined angular position into a complete closed position and / or into a complete open position,
• damping device for damping a hinge movement, wherein the damping device comprises at least one fluid chamber in which a piston is accommodated with a piston rod for performing a running in one direction damping stroke, wherein the effective direction of the coil spring and the direction of Dämpfungshubes laterally spaced parallel or obliquely to each other run.
• a damping device for furniture hinges wherein a piston is slidably mounted in an interior of a housing.
• a guided out of the housing piston rod is provided, which is connectable via a connecting element with a hinge pin of a furniture hinge.
• the piston rod is pressed over the moving hinge pin, so that this hinge movement runs off steamed.
• a spring-assisted locking mechanism would have to be provided.
• the additional arrangement of such a locking mechanism would require an increased space and an additional installation effort.
• a furniture hinge with a closing spring and a braking device in the form of a piston-cylinder unit is shown, wherein the effective direction of the closing spring and the direction of the linear damping stroke are laterally spaced apart in parallel.
• DE 20 2007 004 621 U1 a multi-link hinge with a closing spring and with a linear damper for damping a spring-assisted retraction movement is shown, wherein the closing spring and the linear damper are formed as separate components.
• the effective direction of the closing spring and the direction of the damping stroke of the linear damper run obliquely to each other.
• Object of the present invention is to provide a furniture hinge of the type mentioned with a more compact design. This is achieved by the features of claim 1. Further advantageous embodiments of the invention are specified in the dependent subclaims.

• Another advantage of this unit is also to be seen in the fact that the onset of the force of the spring device and the beginning of action of the damping device can be well timed with each other, because the spring device and the damping device are controlled at the same time with a change in angle of the furniture hinge.
• This is particularly advantageous in wide-angle hinges with at least five or more joint axes, by which an opening angle of a movably mounted furniture part relative to a front side of a furniture body of at least 150 °, preferably at least 170 °, can be achieved.
• a particular challenge in such furniture hinges with an enlarged opening angle range is to synchronize the onset of the force of the spring device and the start of action of the damping device with each other.
• Such a synchronization can, for example, be made to the effect that a control cam is arranged on a hinge axis of the furniture hinge, which is motion-coupled with a hinge movement.
• the coil spring can interact via a pressure piece with this control cam, wherein the entire assembly - consisting of carrier, coil spring and damping device - twisted at a movement of the furniture hinge to those hinge axis on which the control cam is arranged.
