Abstract
A caliper brake for elevator systems has at least one, and preferably two, brake calipers. Each brake caliper has at least one brake pad on a respective brake arm pivoted at a fulcrum. The brake caliper can be swiveled at least into a ready position and into a braking position. The brake arm is elastic and preferably embodied at least partly as a leaf spring.

A caliper brake for an elevator system including at least one brake caliper comprising:
- a brake pad;
- and
- a brake arm having the brake pad positioned at one end of the brake arm, a pivot point at another end of the brake arm and a fulcrum situated between the ends of the brake arm wherein the brake caliper is adapted to be swiveled between a ready position and a braking position, and wherein the brake arm is elastic
An elevator system having an elevator car movable along a guiderail comprising:
- a caliper brake attached to the elevator car and having a pair of brake calipers adapted to be swiveled between a ready position and a braking position, each of the brake calipers including,
- a brake pad for engaging the guiderail in the braking position;
- and
- a brake arm having the brake pad positioned at one end of the brake arm, a pivot point at another end of the brake arm and a fulcrum situated between the ends of the brake arm wherein the brake arm is elastic.
A method for generating a press-on force in a caliper brake engaging a guiderail comprising the steps of:
- bringing a brake arm from a ready position into a braking position to generate the press-on force;
- and
- deforming the brake arm perpendicular to a length of the brake arm in a range of 10% to 2% of the length to generate the press-on force.
