Parking brake

A braking device for an elevator system for generating a frictional connection on a rail of the elevator system and for stopping an elevator car in a stopping place, the braking device comprising:

• two limbs each having a brake end;
• a first limb of the limbs being hingedly connected to a first articulation point of a transmission lever that has a second articulation point spaced apart from the first articulation point in a longitudinal direction of the transmission lever, the second articulation point being hingedly connected to a first pivot of a pressure lever;
• a second limb of the limbs being hingedly connected to a second pivot of the pressure lever;
• a third pivot of the pressure lever being hingedly connected to an articulation point of an actuating element wherein, as a result of a longitudinal movement of the actuating element, the braking device is moved between a braking position, in which the brake ends are at a predetermined minimum distance from one another, and an opened position, in which the brake ends are at a predetermined maximum distance from one another;
• wherein the longitudinal movement of the actuating element is predetermined by a first end point and a second end point;
• and
• wherein an end region of the actuating element is hingedly connected to a crank that can be rotated by 180° between two dead centers, the two dead centers determining the first end point and the second end point of the longitudinal movement of the actuating element.
