    Abstract: A joint is provided for the unfolding and locking of space elements, such as solar generator panels. On one joint half, a detent lever is swivellably connected having a clamping nose as well as a finger as the guiding element. During the unfolding operation, the finger slides on a guiding contour of the other joint half. Shortly before the fully unfolded condition is reached, the finger engages in a depression, and the clamping nose runs up onto a cam and clamps down on the latter under the effect of the spring tension directed to the common axis of rotation. A movable stop element, e.g. universal ball joint, simultaneously presses against a stop surface so that both joint halves are braced with respect to one another. An arrangement of high stiffness which is as free from play as possible results.

    Abstract: The panel sections of a solar collector, for example of a spacecraft, are ld or mounted in a folded down condition at least during launching and until they are unfolded. For this purpose a hold down device that must be released for the unfolding, is used. The device includes a piece of flexible rope or cable, one end of which is connected to the spacecraft body, while the other end is connected to the outermost panel section to hold all panel sections in the folded condition against forces tending to unfold the panel sections, until the rope or cable is severed by a severing mechanism. The effective cable length is adjustable and an elastic member is so arranged that it can dampen shocks and compensate for different temperature responsive expansions of the rope or cable and of the collector structure.

    Abstract: Foldable panels of a solar collector, for example for a satellite, have a plurality of panel sections hinged to each other. At least one outer panel section of each panel is foldable into a position of about 90.degree. to the yet unfolded panel sections. The power needed for the partial unfolding and subsequent complete unfolding is provided by power storing devices, such as mechanical springs. The inward end, relative to a mounting such as a satellite body, of the outer panel section and an outward end of a further inwardly located panel section, for example the next but one inwardly located panel section, are equipped with rigid stop members extending in an extension of the plane of the respective panel section. The stop member of the outer panel has a cam surface (10) cooperating with a facing surface (12) of the stop member of the inner panel section in such a way that the two stop members will maintain the partially unfolded state in the absence of a further unfolding force application and so that the outer stop member cam surface (10) can clear the facing surface (12) in response to such further unfolding force.
