Abstract

PURPOSE:To enable locking and unlocking of wheels by a solenoid in addition to a pedal type operating means. CONSTITUTION:An operating arm 5 is attached to a rotating shaft 4 for transmitting power with which locking operation of a lock mechanism of a caster 2 is made. Also the operating arms 5 are connected associatably to each other by means of an interlocking arm 6. Then a pedal type operating means 7 is attached to either of the rotating shafts 4 of the casters 2, and a solenoid 9 for driving the operating arm 5 rotatably to either of the operating arms 5 through a driving arm 8. By this, all casters can be locked and unlocked by either an electric or manual means. When power fails, a driving arm for the solenoid 9 as a driving source is free to move and, therefore, the caster 2 can be locked and unlocked without any resistance. Thus this mechanism is useful sufficiently in an emergency.

When the solenoid is energized in order to lock the caster, the solenoid excites and pushes the drive arm or pulls the drive arm. Then, the operating arm is rotationally displaced, and the rotary shaft of the lock mechanism is rotated. As a result, the lock mechanism operates to lock the wheels. At that time, the displacement of one working arm is transmitted to the remaining working arms, and all casters are locked. Further, in order to release the lock, the solenoid is energized in the opposite direction to that of the lock operation so that the drive arm is interlocked.
