Patent ID: 7849972

Claim:
A safety device for an elevator, comprising: a pair of pivot levers provided to a car guided by a guide rail, the pair of pivot levers being pivotable about a pair of pivot shafts that are parallel to each other; a plurality of braking members each provided to each of the pivot levers, the plurality of braking members being capable of coming into and out of contact with the guide rail through pivotal movement of the pivot levers; a connecting member pivotally connected to connecting portions of the pivot levers, the connecting portions located on opposite ends of the connecting member along a plane formed by a longitudinal axis of the connecting member; and an electromagnetic actuator configured to push the connecting member in a first direction to pivot the pivot levers in a braking direction to bring the braking members into contact with the guide rail and to pull the connecting member in a second direction to pivot the pivot levers in a releasing direction to bring the braking members out of contact with the guide rail, wherein the connecting portions of the connecting member with the pivot levers are arranged on the same side with respect to a plane containing axes of the pivot shafts, and wherein the electromagnetic actuator causes the connecting member to undergo reciprocating displacement in a direction perpendicular to the plane.
