FRICTION STOP DEVICE

摘要

Described are deployment apparatuses that include a deployment object, a deployment arm with a first end coupled to the deployment object and a second end having a pivot, and a hinge assembly rotatably attached to the pivot of the deployment arm. The hinge assembly includes an enclosure and a friction stop device disposed within the enclosure such that the friction stop device includes a friction portion configured to be pressed against a lateral surface of the pivot 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 such that the deployment object is held in a raised deployed position.
