Display retract mechanism
First Claim
1. A display retract mechanism for moving a display from a deployed position to a retracted position, comprising:
- a frame adapted for holding a display;
a pivot shaft defining a pivot axis, the pivot shaft rotatable around the pivot axis from the retracted position to the deployed position;
a lever arm fixed to the pivot shaft;
a gas spring biased toward the retracted position, the gas spring hingedly connected to the lever arm; and
a drive mechanism for rotating the pivot shaft around the pivot axis from the retracted to the deployed position.

Abstract
A display retract mechanism for moving a display between a retracted position and a deployed position is disclosed and explained. The display retract mechanism is useful, for example, in mounting a liquid crystal display within the cabin of a passenger vehicle, such as an aircraft or bus. A geared chain drive supplies torque necessary for rotating a pivot shaft on which the display is attached. The display is biased toward a retracted position by a gas spring with a substantially linear force curve between the retracted position and the deployed position. Also disclosed are an infrared sensor for detecting when the display is in the deployed position, a solenoid latch for holding the display in the retracted position, and an electromechanical clutch for maintaining the display in a particular position.

26. A display retract mechanism for moving a display from a deployed position to a retracted position, comprising:
-
a frame for holding a display;
a pivot shaft, the frame attached thereto along a pivot axis, the pivot shaft rotatable around the pivot axis from the retracted position to a deployed position;
a lever arm attached to the pivot shaft;
a gas spring biased toward the retracted position, the gas spring hingedly connected to the lever arm;
detector means for detecting when the display is in the retracted position; and
drive means for supplying torque to the pivot shaft, in order to rotate the frame around the pivot axis from the retracted position to the deployed position. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34, 35, 36)

37. A method for moving a display from a deployed position to a retracted position, the method comprising the steps of:
-
holding the display in a frame;
rotating a pivot shaft around a pivot axis, the frame attached to the pivot shaft along the pivot axis;
fixing a lever arm to the pivot shaft, the lever arm compressing a gas spring as the pivot shaft is rotated around the pivot axis from the retracted position to the deployed position; and
supplying torque to the pivot shaft for rotating the pivot shaft from the retracted to the deployed position with a drive mechanism. - View Dependent Claims (38, 39)
