ABSTRACT:
A locking arrangement for unfoldable solar generators which consist of several panels provides a lockable, partially-unfolded, intermediate position and a lockable, completely unfolded final position. In the partially-unfolded position, a panel is pivoted by 90.degree. so that a lock pin which is acted upon by a radially inwardly directed spring force and which, at first, slides on an outer section of a curve of a guiding contour, locks into an opening of a curved slot in a guiding element having the guiding contour. During the transition into the fully unfolded position, a plate cam, which had stopped at first, is rotated so that its driving groove can accommodate the lock pin which can now continue to slide on an inner section of the curve into the final locking position.
