Title:
HOISTING CHAIN ENTANGLEMENT PREVENTING DEVICE FOR PARKING SYSTEM
Document Type and Number:
Japanese Patent JP3165375
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To simultaneously prevent the entanglement of a lifting chain and the downward shifting of a pillow block by fixing an entanglement preventing member having a regulating section for releasing the lifting chain and a contact part contacted with the lower end of the pillow block to a strut by bolts, the pillow block being attached to the strut.
SOLUTION: An entanglement preventing member 42 includes a regulating section 44 for releasing lifting chains 32 and 33 from sprockets 37 and 38 in an upper part 43 and guiding the same in lower directions, a contact section 45 contacted with the lower end of a pillow block 27 and a base part 47 fixed to a strut 15 by bolts. Thus, when the lifting chains 32 and 33 are firmly engaged with the sprockets 37 and 38 to be caught, the upper part 43 of the regulating section 44 releases such engagement. Also, when a large load is applied and the pillow block 27 is shifted downward by an amount equal to the oblong hole as fitting hole, since the contact part 45 is in contact with the lower end thereof, such shifting is prevented.
