ABSTRACT:
A joint for deploying and locking a solar panel or a reflector has a fork which is pivotable through 180.degree. about a common pivot axis with a fixed bearing support. A disk mounted on the fixed bearing support has a sliding curve that terminates in a groove. A latching fork mounted rotatably on pivotable fork has a latching bolt and sliding roller which runs on the sliding curve when the pivotable fork deploys, and together with a latching bolt, engages the groove. A leg spring engages the latching bolt. The sliding curve has a shape such that during the first half of a deployment angle of the fork that is pivoted by the force of a coil spring, a decreasing portion of the coil spring moment is stored in leg spring. In the second half of the deployment angle, a moment 16 stored in leg spring 9 is again added increasingly to the movement, so that during deployment, an approximately constant corrected deployment moment is provided.
