Abstract
An elevator with a brake device may be configured to provide a variable brake force, from a minimum brake force up to a maximum brake force (Vmax). The brake device may include a first energy store that provides the maximum brake force and a second energy store that provides an adjustable counterforce. The adjustable counterforce may be directed in an opposed manner with respect to the maximum brake force provided from the first energy store. Further, the variable brake force may amount to a difference between the maximum brake force and the adjustable counterforce. In some cases, the first energy store may comprise a compression spring for providing the maximum brake force.

An elevator comprising a brake device configured to provide a variable brake force from a minimum brake force up to a maximum brake force, the brake device comprising:
- a first energy store for providing the maximum brake force;
- a second energy store for providing an adjustable counterforce that is directed in an opposed manner with respect to the maximum brake force, wherein the variable brake force amounts to a difference between the maximum brake force and the adjustable counterforce;
- a first triggering path and a second triggering path for triggering the brake device, wherein the brake device provides the variable brake force when the first triggering path is active, wherein the brake device provides the maximum brake force when the second triggering path is active;
- and
- a triggering element for activating the second energy store when the second triggering path is active, wherein the second energy store is decoupled from the first energy store after activation of the second energy store.
A brake device for an elevator, the brake device being configured to provide a variable brake force from a minimum brake force up to a maximum brake force, the brake device comprising:
- a first energy store for providing the maximum brake force;
- a second energy store for providing an adjustable counterforce that is directed in an opposed manner with respect to the maximum brake force, wherein the variable brake force amounts to a difference between the maximum brake force and the adjustable counterforce;
