Patent JP-H08230748-A (JP)
Title: Power assisted bicycle
Inventor: KAAI MASAFUMI
IPC: B62M19/00
Filed: 1995-02-28
Abstract: PURPOSE: To make it possible to effectively utilize turning force of a wheel at the time of braking by supplying hydraulic pressure to a motor when required and giving the wheel auxiliary driving force after supplying operation fluid by means of turning force from the wheel at the time of braking and accumulating the pressure in an accumulator. CONSTITUTION: When a rear manual brake lever 26 is pulled, a distributing valve 30, resisting to the energetic force of a spring 51, is switched over and respective ports 30a to 30d communicate with each other. For this reason, a hydraulic motor 38 rotated by the turning force of the rear wheel operates as a hydraulic pump. Operation oil stored in a lower pressure accumulator 34 is discharged and accumulated in a high pressure accumulator 32 through respective pipings 33, 37, 35, 31. As a result, negative load resisting to the turning is produced in the hydraulic motor 38 and becomes braking force which restrains the turning of a sprocket 39, or in other words, the rear wheel. When the rear manual brake lever 26 is released, operation oil accumulated in the high pressure accumulator 32 is discharged and drives the hydraulic motor 38.  Thus the hydraulic motor 38 turns the rear wheel and provides power assisting.

Abstract: PROBLEM TO BE SOLVED: To provide a relay of which contacts are prevented from a trouble such as contact melting and deposition. SOLUTION: A first card 55 is rotated by being pushed by a projected part 37 and bends a main movable spring 46. At that time, a pushing part of the first card 55 pushes an object pushing part 74 to be pushed of a second card 72 and the second card 72 is driven along a groove. An arc movable spring 48 is sandwiched between the second card 72 and a projected part 73 and the second card 72 bends the arc movable spring 48 by driving the second card 72 by the first card 55. At the time of turning on a relay. the first card brings the main movable contact into contact with a main fixed contact in a state that the second card 72 brings the arc movable contact into contact with an arc fixed contact and then the arc movable contact and the arc fixed contact are parted from each other.  On the other hand, at the time of turning off the relay, the first card 55 parts the main movable contact from the main fixed contact.
