<p>The actuator for a double leaf door operates two arms which are connected to the leaves in opposition. A motor (5) operates one (4) of two pulleys (4,4') and the operating cable (6) is a figure of eight with a longitudinal axis (7) in a single plane. There are two complementary straight rigid sections of the cable which cross to form loops (10,10').</p> |
