Claims
- 1. A braking device for an elevator with an elevator car and an counterweight movable along guide rails in an elevator shaft, wherein the braking device is arranged at the elevator car or at the counterweight and in the case of excess speed stops the elevator car or the counterweight at the guide rails by means of spring elements and brake chocks, comprising: a plurality of spring elements of modular construction, said spring elements being selectively assembled for generating different braking forces, wherein said spring elements each are one of a spring packet and an adjusting packet and said spring packet and said adjusting packet are detachably connected at ends thereof with chock guide elements guiding the broke chocks.
- 2. The braking device according to claim 1 wherein said spring packet and said adjusting packet are C-shaped.
- 3. The braking device according to claim 1 wherein said spring packet is arranged at a support body that acts on said chock guide elements.
- 4. The braking device according to claim 3 wherein said support body has an associated groove formed therein for reception of each said spring packet.
- 5. A braking device for an elevator with an elevator car and a counterweight that are movable along guide rails in an elevator shaft, wherein the braking device is arranged at the elevator car or at the counterweight and in the case of excess speed stops the elevator car or the counterweight at the guide rails with spring elements and brake chokes, wherein the spring elements are of modular construction and generate different braking forces, comprising: a plurality of spring elements constructed from lamellae producible in a simple manner, each of said spring elements being one of a spring packet and an adjusting packet, each said spring packet being arranged at a support body that acts on chock guide elements guiding the brake chocks.
- 6. The braking device according to claim 5 wherein said spring elements are C-shaped.
- 7. The braking device according to claim 5 wherein said spring elements are detachably connected at ends with chock guide elements guiding the brake chocks.
- 8. The braking device according to claim 5 wherein said support body has an associated groove formed therein for receiving each of said spring packets.
- 9. The braking device for attachment to one of an elevator car and a counterweight that are movable along guide rails in an elevator shaft, wherein the braking device is actuated to engage a guide rail in the case of excess speed, comprising:a housing; a pair of brake chocks mounted on said housing and movable from a disengaged position to a guide rail engaging position; and at least one spring packet mounted on said housing and having opposed ends connected to associated ones of said brake chocks, said at least one spring packet being of modular construction having lamellae selected to produce a predetermined braking force, and including at least one adjusting packet mounted on said housing and having opposed ends connected to an associated one of said brake chocks.
- 10. The braking device according to claim 9 wherein each end of said spring packet is detachably connected to said associated brake chock by a spring bracket.
