Abstract: 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.

Abstract: A stowable display apparatus is disclosed that includes a base adapted to be mounted on the ceiling of a vehicle, such as an automobile, and a display unit that is mounted on the base. The display unit is pivotal with respect to the base in a range of positions between a stowed position, in which the unit is retained proximate the base and generally parallel to the ceiling of the vehicle, and a deployed position, in which the unit is pivoted away from the base into the passenger compartment of the vehicle. The display unit further includes a push-button mechanism that selectively engages the display unit to retain the unit in the stowed position. The mechanism includes a push-button actuator that is moveable between a rest position, in which the mechanism is positioned to engage the display unit, and a depressed position, in which the actuator is moved toward the base and the mechanism freed from engagement with the display unit, thereby enabling the display unit to pivot away from the stowed position.
