发明名称 Automatic futon frame
摘要 A futon frame includes a seat having a pair of electric motors mounted at opposite sides thereof for driving a pair of pinions arranged to engage inclined toothed racks mounted on each side of the frame for automatically and continuously adjusting the seat and a hingedly connected back between a sofa position and a bed position. Follower pins fixed relative to the seat are arranged to slidably engage matching guide surfaces above the toothed racks. The back is connected to opposite sides of the frame by a pair of link arms pivotal at each point of connection. A motor controller is mounted to the underside of the seat for connecting a user interface to the motors.
