<p>A door (1) pivots on a hinge (2) to contact a door stop (3) in the closed position. A plate (5) pivots on an axis (6) and between two opposing return torques provided by a square section (7) fixed cylindrical sections (8) of flexible material. Two switches (15, 16) on the plate are operated by a mounting plate (11) when the pivot plate takes up its pivot positions (13, 14). A pulley (17) is rotated by an electric motor and reduction gear (30) to drive a belt (21) attached to brackets (22) on a tube (23) into which a shaft (24) travels to provide a flexible door stop.</p> |
