Abstract

A locking wheeled locking carrier including a pair of identical molded half carriage parts each of which carries a pair of canted wheels to support the carrier within a track, and a pendulum part pivoted between the carriage halves and extending downward through the bottom slot in the ceiling track for suspending a desired article. The two carriage halves are slidably interfitted with one another for lateral movement toward and away from one another within the ceiling track, and the pendulum pivot extends slidably through both carriage halves. In the vertical pendulum position a camming action exerted by the pendulum on the two carriage halves forces the carriage halves laterally apart from one another so that their outside surfaces engage the ceiling track slot walls and frictionally lock the carriage in position. When the pendulum is pivoted longitudinally in either direction relative to the carriage halves and the running length of the ceiling track the lateral camming action exerted by the pendulum on the carriage halves is released so that the outer surfaces of the carriage halves disengage from the ceiling track slot wall side surfaces and the carriage is free to travel through the track, it being relockable in its new position by again moving the pendulum to its vertical position.
