Emergency stop device for elevator
Abstract:
An emergency stop device for an elevator, including: a supporting member; a receiving-side braking member provided to the supporting member; a pressing-side braking member for gripping a guide rail together with the receiving-side braking member by being displaced upward with respect to the supporting member while being guided by an inclined guide portion of the supporting member; and an adjusting elastic member for generating an elastic restoring force acting against the upward displacement of the pressing-side braking member. A magnitude of a gripping force, which is generated when the guide rail is gripped between the receiving-side braking member and the pressing-side braking member, increases as the pressing-side braking member is displaced upward with respect to the supporting member. A magnitude of the elastic restoring force of the adjusting elastic member increases as the pressing-side braking member is displaced upward with respect to the supporting member.
