US 9,169,104 B2 · Activating a safety gear

Abstract

In this elevator system, a traveling body has arranged upon it a safety gear for braking and holding the traveling body tight on the guiderail, or on a braking rail. The safety gear is connected to a device for actuating the safety gear, which can also actuate the safety gear. The device for actuating the safety gear contains a coupler body, which can be pressed against the elevator hoistway, possibly against the guiderail or braking rail, wherein actuation of the safety gear is effected by a relative movement between the pressed-on coupler body and the safety gear. For this purpose, the coupler body can contain a curved coupler surface, which, in case of need, is brought into engagement with the elevator hoistway, or with the guiderail or braking rail.

Dependent claims

An elevator system, comprising:

a traveling body, the traveling body being configured to travel along a guiderail in an elevator hoistway;
a safety gear, the safety gear being arranged on the traveling body and configured to brake and hold the traveling body on the guiderail or on a braking rail;
and
a safety gear actuating device, the safety gear actuating device being arranged on the traveling body and connected to the safety gear, the safety gear actuating device comprising at least one coupler body configured to be pressed against the guiderail or the braking rail, the safety gear being activatable by a relative movement between the pressed coupler body and the safety gear, the coupler body comprising a coupler surface arranged swivelably about a swivel axle in the safety gear actuating device, the coupler surface being configured such that a force of the coupler body on the guiderail or the braking rail increases over a swivel range of the coupler body.
