SERVO DRIVE FOR FURNITURE LEAVES Russian patent published in 2018 - IPC E05F1/10 

FIELD: construction.

SUBSTANCE: servo drive comprises an actuating lever mounted with the possibility of rotation around the rotation axis for moving the leave; a spring device for applying a force to the actuating lever; a transmission mechanism for transferring the force of the spring device to the actuating lever in the closing direction and, after passing through the dead point, to transfer the force of the spring device to the actuating lever in the opening direction; and an adjusting device, by means of which it is possible to change the position of the servo drive in or on the guide. The servo drive has a connecting device that connects the spring device, the rotation axis of the actuating lever, and the actuating element to one another. Due to the rearrangement of the actuating element in or on the guide, the possibility of variable setting of the dead point in the actuating lever, as well as of the force of the spring device, acting in the opening direction on the actuating lever, is ensured, so while increasing said force acting in the opening direction, the possibility of reducing the rotation angle of the actuating lever, in which the dead point position is, is also ensured.

EFFECT: reducing the retention force of the actuating lever in the closing position at high torques.
