SOLENOID FOR PREVENTING FALLING OF PALLET OF LIFTING-LOWERING TYPE PARKING SPACE

摘要

PURPOSE: To detect the positions of a plunger respectively at two front and rear places, and to collect solenoids compactly. ;CONSTITUTION: When solenoids are excited, a plunger 7 at a forward position elastically shrinks a return spring 9, and is retreated together with an actuating lever 15. The front end section of the section to be detected 16 of the actuating lever 15 is abutted against an abutting member 25 on its midway of the operation of the plunger 7, and the section to be detected 16 depresses a second microswitch 28 and the microswitch is turned on. The actuating lever 15 elastically shrinks an auxiliary spring 18 and the plunger 7 is further retreated while the actuating lever 15 and the auxiliary spring 18 are entered relatively into a guide cylinder 14 as shown by a chain line by succeeding excitation, and chips 11 made of a rubber on a rear surface are abutted against a frame 1a on the rear side and the plunger 7 is stopped at the position of a retreat. The second microswitch 28 is left as its is turned on at that time. When excitation is released. the plunger 7 is projected to the forward position while the actuating lever 15 is returned to an original place, thus turning a first microswitch 27 on.;COPYRIGHT: (C)1995,JPO
