ABSTRACT:
Synchronized angular displacement of articulated elements of an outwardly-extendable solar-cell panel is carried out by means of a device mounted between any two successive panel elements constituting a driving element and a driven element. Two independent and parallel traction members are pivotally mounted on support plates which are rigidly fixed to two successive driving elements. Two link-arms for traction members such as cables are pivotally attached to pins forming anchoring points for the cables. Each support plate has two stationary stops for limiting the angular displacements of the link-arms during the relative pivotal movement of the driven element with respect to the driving element.
