An apparatus is described which includes a frame, a video monitor display mounted to the frame, a torque shaft coupled to the frame such that rotation of the torque shaft causes the frame to pivot along a predetermined arc. The apparatus further involves engaging to the torque shaft to impart rotational motion to the torque shaft, a releasable cam follower slidably disposed on the cam shaft and a spring mounted on the cam shaft exerting a spring bias force directed toward the cam so as to cause rotational motion of the cam.

1. An apparatus comprising:a frame; a video monitor display mounted to the frame; a torque shaft coupled to the frame such that rotation of the torque shaft causes the frame to pivot along a predetermined arc; a cam having a cam shaft with a first end and a second end, the cam operatively coupled to the torque shaft for imparting rotational motion to the torque shaft; a releasable cam follower slidably disposed on the cam shaft first end such that upon rotation of the cam the cam follower moves along the cam shaft toward the second end; a spring mounted on the cam shaft second end having a spring bias force directed toward the cam shaft first end, the spring operatively coupled to the cam so as to cause rotational motion of the cam.
