Abstract
Deployment apparatus (10) including a deployment object (12), a deployment arm (16) with a first end (22) coupled to the deployment object and a second end (24) having a pivot (26), and a hinge assembly (18) rotatably attached to the pivot of the deployment arm. The hinge assembly (18) includes an enclosure (44) and a friction stop device (82) disposed within the enclosure such that the friction stop device includes a friction portion (80) configured to be pressed against a lateral surface of the pivot (26) of the deployment arm such that the friction portion provides a predetermined torque. The predetermined torque may be calculated based on maintaining a deployed angle of the deployment arm (16) such that the deployment object (12) is held in a raised deployed position.
