Abstract
A braking device may include first and second brake pads disposed opposite one another about a guide rail, for developing braking forces when the brake pads engage the guide rail. The first brake pad has a wedge shape and may taper in a wedge direction. A front side of the first brake pad facing the guide rail is aligned parallel to the guide rail, and a rear side of the first brake pad is angled corresponding to the wedge shape. The rear side of the first brake pad lies in a sliding manner against a contact surface of a first brake pad seat disposed at an angle corresponding to the first brake pad. In a first setting a locking device unblocks a sliding movement of the first brake pad, and in a second setting the locking device blocks the sliding movement of the first brake pad.
