Abstract

PURPOSE: To attain various moving speeds in a multistage manner, by engaging movable nuts with expansible and contractible screw shafts for a lifter or the like and using separate motors to drive the shafts to move a body at a speed corresponding to the resultant velocity of the motors.
CONSTITUTION: A hollow shaft 7 is screw-engaged with a movable nut on a frame 16 so that the shaft 7 is rotated by a motor 33 through sprockets 32, 35. A screw shaft 6 inserted in the hollow shaft 7 is screw-engaged with a movable nut which is provided on a support 5 borne on the upper end of the hollow shaft 7 and is not shown in the drawing. The screw shaft 6 is rotated by a motor 11 through sprockets 9, 15. The upper end of the screw shaft 6 is supported by a secured member 4. According to this constitution, a body 1 can be moved at a speed corresponding to the resultant revolution speed of the screw shafts 6, 7 and the movable nuts. Various moving speeds can be attained by combining such members together in a multistage manner.
