Method and apparatus for electronically controlled resistance in exercise equipment
A system for controlling the tension in an exercise apparatus includes a plurality of connectors that are collectively attached to a holder, the holder being movable relative to a fixed support, each connector further comprising a catch for independent attachment to a tension member from an exercise apparatus. Different combinations of tension members can be attached to the connectors with an electronic control system to create a desired tension arrangement, while the holder including all of the connectors can be moved to further fine tune the tension arrangement of the tension members.
1. A system for controlling a tension in an exercise apparatus comprising:
a) a fixed support;
b) a plurality of connectors that are collectively attached to a holder, the holder being movable relative to the fixed support, each of the plurality of connectors further comprising a catch for attachment to a tension member of a plurality of tension members from an exercise apparatus;
c) a plurality of guides that are respectively associated with the plurality of connectors;
d) each of the plurality of guides being independently movable between a first position for positioning the tension member relative to the catch where the catch is inaccessible for attachment to the tension member, and a second position where the catch is exposed for attachment to the tension member, wherein each of the plurality of guides further comprises an opening for passage of the catch in the second position and a ramp for guiding the tension member into the first position away from the opening; and
e) a control system for controlling the movement of the plurality guides for selective attachment of the tension members to the catches, and for controlling the movement of the holder for controlling the tension of the tension members attached to the catches.
2. The system of claim 1 , wherein the control system is an electronic control system.
3. The system of claim 2 , wherein the control system further comprises a display.
4. The system of claim 1 , further comprising an actuator associated with each of the plurality of connectors for moving the guide between the first and second positions.
5. The system of claim 4 , further comprising another actuator associated with the holder for moving the holder relative to the fixed support.
6. The system of claim 1 , wherein the ramp further comprises angled side walls.
7. The system of claim 1 , wherein the catch further comprises a hook.
8. An exercise device comprising:
a) a fixed support;
b) a plurality of tension members;
c) a plurality of connectors that are collectively attached to a holder, the holder being movable relative to the fixed support, each of the plurality of connectors further comprising a catch for attachment to a tension member of a plurality of tension members;
d) each of the plurality of connectors being independently movable relative to the respective tension member between a first position where the tension member is aligned with but not attached to the catch, and a second position where the tension member is aligned with and attachable to the catch;
e) a plurality of guides that are respectively associated with the plurality of connectors, each of the plurality of guides being independently movable between the first position for positioning the tension member relative to the catch where the catch is inaccessible for attachment to the tension member, and the second position where the tension member is attachable to the catch, wherein each of the plurality of guides further comprises an opening for passage of the catch in the second position and a ramp with angled side walls for guiding the tension member into the first position away from the opening; and
f) a control system for controlling the movement of the holder for controlling the tension of the tension members attached to the catches.
9. The exercise device of claim 8 , further comprising an actuator associated with each of the plurality of connectors for moving the connectors between the first and second positions.
10. The exercise device of claim 9 , further comprising another actuator associated with the holder for moving the holder relative to the fixed support.
11. The exercise device of claim 10 , further comprising an electronic input/output subsystem associated with the control system.
12. The exercise device of claim 11 , further comprising an electronic data holding subsystem associated with the control system.
13. The exercise device of claim 8 , wherein the catch further comprises a slidable rod.
14. The exercise device of claim 8 , wherein the catch further comprises a hook rotatably attached to the holder.
15. The exercise device of claim, 8 , wherein the tension members are movable in a first plane and the holder is movable in a second plane that is different from the first plane.
