Abstract

A connector apparatus connects a first component of an exercise machine to a second component of the exercise machine. The connector apparatus comprises a rack coupled to the first component; a pinion gear coupled to the second component, the pinion gear being configured to mate with the rack such that the pinion gear can roll along the rack; a one-way bearing that allows the pinion gear to roll along the rack in a first direction and prevents the pinion gear from rolling along the rack in an opposite, second direction; and a handle that is coupled to the one-way bearing. The handle is configured to move back and forth between a first position wherein the pinion gear is mated with the rack and allowed by the one-way bearing to roll along the rack in the first direction and prevented by the one-way bearing from rolling along the rack in the second direction; and a second position wherein the pinion gear is separated from the rack and is freely movable in the first and second directions.

First claim

What is claimed is:

1. A connector apparatus that connects a first component of an exercise machine to a second component of the exercise machine, the connector apparatus comprising:
a rack coupled to the first component;
a pinion gear coupled to the second component, wherein the pinion gear is configured to mate with the rack such that the pinion gear can roll along the rack;
a one-way bearing that allows the pinion gear to roll along the rack in a first direction and prevents the pinion gear from rolling along the rack in an opposite, second direction; and
a handle that is coupled to the one-way bearing, wherein the handle is configured to move back and forth between
i. a first position wherein the pinion gear is mated with the rack and allowed by the one-way bearing to roll along the rack in the first direction and prevented by the one-way bearing from rolling along the rack in the second direction; and
ii. a second position wherein the pinion gear is separated from the rack and is freely movable in the first and second directions.

2. The apparatus according to claim 1 , comprising a spring that biases the handle into the first position.

3. The apparatus according to claim 2 , comprising a bracket that supports the pinion gear.

4. The apparatus according to claim 3 , wherein the bracket comprises a pair of ears, and further comprising a stationary shaft that is supported by the pair of ears, wherein the pinion gear rotates about the stationary shaft.

5. The apparatus according to claim 4 , wherein the stationary shaft is keyed to the bracket.

6. The apparatus according to claim 4 , wherein the handle comprises a knob and an elongated shaft that has a first end attached to the bracket and an opposite second end attached to the knob.

7. The apparatus according to claim 6 , wherein the spring is disposed on the shaft, wherein the spring axially biases the pinion gear into the first position, and wherein pulling on the handle against the spring moves the pinion gear into the second position.

8. The apparatus according to claim 2 , wherein the handle is pivotable with respect to the second component.

9. The apparatus according to claim 8 , wherein the handle is connected to a pivot shaft coupled to the second component and wherein the spring is a torsion spring disposed on the pivot shaft.

10. The apparatus according to claim 9 , wherein pivoting the handle against the spring moves the pinion gear into the second position.

11. The apparatus according to claim 1 , wherein the first component comprises a weight and the second component comprises a weight rack.

12. An exercise machine, comprising:
a first component;
a second component;
connector apparatus comprising
a rack coupled to the first component,
a pinion gear coupled to the second component, wherein the pinion gear is configured to mate with the rack such that the pinion gear can roll along the rack,
a one-way bearing that allows the pinion gear to roll along the rack in a first direction and prevents the pinion gear from rolling along the rack in an opposite, second direction, and
a handle that is coupled to the one-way bearing, wherein the handle is configured to move back and forth between
i. a first position wherein the pinion gear is mated with the rack and allowed by the one-way bearing to roll along the rack in the first direction and prevented by the one-way bearing from rolling along the rack in the second direction; and
ii. a second position wherein the pinion gear is separated from the rack and is freely movable in the first and second directions.

13. The machine according to claim 12 , comprising a spring that biases the handle into the first position.

14. The machine according to claim 13 , comprising a bracket that supports the pinion gear, wherein the bracket comprises a pair of ears, and further comprising a stationary shaft that is supported by the pair of ears, wherein the pinion gear rotates about the stationary shaft.

15. The machine according to claim 14 , wherein the stationary shaft is keyed to the bracket, wherein the handle comprises a knob and an elongated shaft that has a first end attached to the bracket and an opposite second end attached to the knob.

16. The machine according to claim 15 , wherein the spring is disposed on the shaft, wherein the spring axially biases the pinion gear into the first position, and wherein pulling on the handle against the spring moves the pinion gear into the second position.

17. The machine according to claim 13 , wherein the handle is pivotable with respect to the second component.

18. The machine according to claim 12 , wherein the first component comprises a weight and the second component comprises a weight rack.
