Definitions

• the present invention relates to an actuator for moving a movably mounted furniture part, comprising:
• a spring device by means of which the actuating arm is retractable within a closing position immediately preceding the closed position in the closed position.
• the spring device of such an actuator is used in addition to a compensation of the weight of the movable furniture part also to collect the furniture part towards the end of the closing movement in the full closed position. This ensures that the furniture part rests in the closed position with a clamping force on a furniture body, remains completely closed and unwanted opening is prevented.
• opening the furniture part it is necessary to apply a manual pulling movement on the furniture part against the force of the spring device.
• a spring device with high spring force is to be provided which additionally increases this clamping force. This can ultimately lead to the furniture part can only be opened with a considerable manual effort, especially if the furniture part mounted as a flap on a wall unit and thus difficult for a person is accessible.
• a generic actuator is described in EP 2 290 182 A1, wherein a compensation device with an energy store is provided to reduce the locking force.
• This energy storage brings on the locking force of the actuator to an opposite force, so that the force required to open the furniture part can be reduced overall.
• the arrangement of such a compensation device also requires an additional spring, which increases the space requirements and the manufacturing cost of the actuator.
• a furniture hinge is shown with a hinge arm and with a hinge cup, wherein in the hinge cup a biased by a spring and with the hinge arm releasably coupled lever for spring-assisted closing movement of the furniture hinge is arranged.
• a spherical projection of the hinge arm can be coupled with a corresponding receptacle of the lever so that the furniture hinge can be retracted by the force of the spring into the closed end position.
• a person In the opening movement, however, a person must apply a manual force against the force of the spring until the spherical projection of the hinge arm releases from the receptacle of the lever and is thus released for further opening movement.
