Patent 7825617 was granted and assigned to Julius Blum on November, 2010 by the United States Patent and Trademark Office.
A drive for a movable furniture part includes a motor to power the movable furniture part and a control or regulation unit to control or regulate the motor. The control or regulation unit is designed such that it has a threshold value which, if surpassed, causes the actuation of the movable furniture part by the motor. A measurement device is provided to capture the position of the movable furniture part, and the control or regulation unit is designed in such a way that the threshold value varies for at least two different positions of the movable furniture part.
