  • Patent number: 9366306
    Abstract: A double-rod type shock absorber includes a rod, first and second pistons held by the rod, first and second piston chambers disposed on an outer side of the first and second pistons, a liquid storage chamber between the first piston and the second piston, a flow path gap formed between an outer peripheral surface of the first and second pistons and an inner peripheral surface of the liquid chamber, and first and second unidirectional flow paths which connect the first and second piston chambers with the liquid storage chamber, wherein, during reciprocating motion of the rod, the unidirectional flow path located on a front side in a movement direction of the rod is closed, and the unidirectional flow path located on a back side in the movement direction of the rod is opened.

  • Patent number: 7032714
    Abstract: Disclosed is a return mechanism for elevator escape device. The return mechanism mounted at a wall of a car and comprises a drive sheave, upper and lower secondary sheaves, a wheel coaxially disposed with the drive sheave and located on an inner wall of the car, a lever including a lower pivot end, a positioning bar, an upper end at the drive sheave, and a groove, a link having one end defined by the groove and a roller at the other end, a support for permitting the link to slide therethrough, a catch, and projecting return members. In a case of car failure, a trapped passenger is able to continuously rotate the wheel for escape in which the mechanism can automatically return to its original position by moving the link backward after the roller contacting the return member.

  • Publication number: 20020100645
    Abstract: A method and equipment is provided to allow a stuck elevator lift cage to be moved in situations when the lift cage and passengers is in weight equalization with the lift counterweight. With the lift's safety brake disengaged and the lift drive unactuated, the drive brake is released and an additional force is applied to the lift cage from a source external to the lift drive to move the lift cage to a position for passenger evacuation. The additional force may be applied through a cable pull connected to the limiter cable of the elevator's speed monitor system.
