Abstract
A system for extending or retracting two rotationally interconnected members and locking or releasing the members in the extended position. The system includes a locking cam (4) on a shaft (5) combined with the first member (2) and connected to a drive (9). The cam is engageable with a bearing surface (8) on the second member. The drive (9) is preferably a power drive rotating the two members about their pivot axis and includes a motor (9A) with a rotational axis (17) parallel to the rotational axes (10, 11) of the cam and the shaft, the rotational axis coinciding with the pivot axis of the two members; a transmission (18) linking the motor to the shaft; and a radial linkage (19) rotating with the motor and capable of rotating the second member about the pivot axis.
