WIPO Patent Application WO/2008/010368
Kind Code:
A1
Abstract:
An eccentric ring-shaped thin governor for a passenger transportation system, capable of being mounted in a narrow space located aside a belt pulley. The governor (11) for a passenger transportation system has a rotator (12a), a base (14) fixed to the rotator (12a), and an eccentric ring (13) rotatably fixed to the base (14) through a rotation mechanism (14a) and having the center of gravity at a position eccentric relative to the center of rotation of the rotator (12a). The base (14) and the eccentric ring (13) are connected together by a restoration mechanism (15) for imparting restoration force to the eccentric ring (13), and the restoration force acts on the eccentric ring (13) to direct it in the direction toward a restoration position. A restoration stopper (16) restrains the eccentric ring (13) to the restoration position.A detection switch (18) in contact with a cam profile (13a) of the eccentric ring (13) during operation of the eccentric ring (13) is provided near the eccentric ring (13), and a controller (20) stops the passenger transportation system by a signal from the detection switch (18).
