Abstract
Apparatuses and methods for providing adjustable levels of resistances are disclosed. In some embodiments, the apparatus comprises a resistance module configured to provide a resistance. In some embodiments, the resistance module is configured to provide a constant-force resistance. In some embodiments, the apparatus comprises a continuously-variable gear for providing a continuously-variable resistance.
Claims18
An apparatus for providing a resistance, the apparatus comprising:
- a resistance module configured to provide a resistance;
- a first gear configured to mate with the resistance module;
- a second gear configured to mate with the first gear;
- a wedge, wherein the wedge is configured to prevent the first gear or the second gear from rotating when the resistance module is not mated with the first gear, and wherein the wedge is configured to allow the first gear and the second gear to rotate when the resistance module is mated with the first gear;
- wherein the resistance module mating with the first gear is configured to activate a lever system, the lever system configured to:
- press against an end of an arm and cause the arm to rotate and disengage the wedge from the first gear or the second gear, or
- activate a rack and pinion system configured to:
- press against an end of the arm and cause the arm to rotate and disengage the wedge from the first gear or the second gear.

An apparatus for providing a continuously-variable resistance, the apparatus comprising:
- a continuously-variable gear, wherein the continuously-variable gear comprises:
- a conical portion, the conical portion comprising a continuously-variable diameter, and
- a cylindrical portion, the cylindrical portion comprising a grooved portion;
- a belt mated with the continuously-variable gear via the conical portion, wherein the belt is configured to cause the continuously-variable gear to rotate;
- a resistance module configured to provide a constant-force resistance, wherein the resistance module is configured to mate with the continuously-variable gear, wherein:
- a rotation of the continuously-variable gear causes the continuously-variable resistance to be provided based on the constant-force resistance;
- and
- a second continuously-variable gear and a second resistance module configured to mate with the second continuously-variable gear, wherein:
- the belt is mated with the second continuously-variable gear via a conical portion of the second continuously-variable gear, and
- the belt is configured to cause the second continuously-variable gear to rotate.
