WEIGHT REGULATOR AND MOVING AUXILIARY DEVICE EQUIPPED THEREWITH

摘要

PROBLEM TO BE SOLVED: To provide a weight regulator capable of setting the mass of a weight without requiring labor, and a moving auxiliary device equipped therewith.

SOLUTION: The mass of the weight 71 supported on an elevator 80 is regulated by changing the number of weight blocks 72 vertically accumulated on the elevator 80. The weight blocks 72 have grooves 73 at the mutually joined parts of them and a pin 75 is inserted in each of the mutually joined holes of the grooves 73 through the pin receiving holes 74 of a support plate 49 provided so as to be made immovable in height. The weight blocks 72 above the pin 75 are not placed on the elevator 80. The pin 75 is attached to the end of the lever 171 provided to a light module 161 and energized toward the grooves 73 by the tensile coil spring 174 tensioned between the lever 171 and a chassis 170. The lever 171 is rotated against the energizing force of the tensile coil spring 174 by a rotary solenoid 175 to pull back the pin 75.
