Apparatus for retracting a protrusion such as an automobile mascot (1) comprises an assembly (15), on which the protrusion is mounted, pivotally connected (via) upper and lower levers (5) and (13) to a structure like an automobile radiator shell (25). A motor (10) and gearbox (9) are drivably connected to lever (5) and are operative to drive the protrusion (1) through an aperture in the stucture (25) between retracted and erected positions. Microswitches (7, 14 and 15F) control the operation of the motor (10). If the protrusion is subject to a force above a predetermined level, the motor is switched on by microswitch (15F) to retract the protrusion. The motor is switched off by microswitch (14) at the downward limit of its travel and by microswitch (7) at the upper limit of its travel. The motor may be operated by manually operable switch means under the control of a microprocessor which remembers the position of the protrusion. |
