ABSTRACT:
Deployment hinge apparatus comprises a stationary U-shaped bracket including a flange defining a retention recess. A hinge arm for supporting an operating structure such as a communication antenna reflector is pivotally mounted on the stationary bracket for movement between a stowed position and a deployed position. The hinge arm includes a deployment and latching cam which extends to a projecting nose member. A latch arm is pivotally mounted at one end to the stationary bracket and includes a cam follower at its other end operatively engageable with the cam. A spring biases the cam follower into engagement with the cam and is thereby effective to rotate the hinge arm from the stowed position to the deployed position such that, in the deployed position, the nose member and the cam follower are together snugly received in the retention recess, locking the hinge arm in the deployed position. In a simplified embodiment, which does not utilize a latch arm or a cam and cam follower, a bearing pivotally mounts the hinge arm on the stationary bracket. A first stop member is provided on the stationary bracket and a second adjustable stop member is provided on the hinge arm positioned to engage the first stop member when the hinge arm is in the deployed position. A spring biases the hinge arm toward the deployed position with the second stop member engaged with the first stop member and is effective to retain the hinge arm in the deployed position.
