Abstract

Claims (35)

1. An exercise machine, comprising:

a plurality of weights arranged in a stack;

a stem; and

a plurality of weight selector switches mounted to the stem, each weight selector switch of the plurality of weight selector switches positioned and configured to selectively couple a corresponding weight of the plurality of weights to the stem;

wherein each weight selector switch of the plurality of weight selector switches includes a sleeve positioned on the stem, a switch body positioned on the sleeve, and a cap positioned on the switch body; and

wherein the sleeve comprises at least two detents and a spring biased ball positioned within the switch body.

2. The exercise machine of claim 1 , wherein each weight selector switch of the plurality of weight selector switches is rotatable relative to the stem.

3. The exercise machine of claim 1 , wherein each weight selector switch of the plurality of weight selector switches comprises at least one lug positioned and configured to selectively enter a corresponding channel in a corresponding weight of the plurality of weights.

4. The exercise machine of claim 3 , wherein each weight selector switch of the plurality of weight selector switches comprises two laterally extending lugs, each laterally extending lug configured to selectively enter a corresponding channel in a corresponding weight of the plurality of weights upon rotation relative to the stem.

5. The exercise machine of claim 1 , wherein each weight selector switch of the plurality of weight selector switches comprises a respective detent mechanism.

6. The exercise machine of claim 5 , wherein each of the respective detent mechanisms comprises a respective spring biased ball located within the stem.

7. The exercise machine of claim 5 , wherein each of the respective detent mechanisms comprises a spring biased ball located within a respective weight selector switch.

8. The exercise machine of claim 1 , wherein the stem comprises a plurality of channels and wherein a portion of each weight selector switch of the plurality of weight selector switches is positioned within a respective channel of the plurality of channels to couple each weight selector switch of the plurality of weight selector switches to the stem.

9. The exercise machine of claim 1 , wherein each weight of the plurality of weights comprises at least one opening positioned to facilitate the passage of a respective lug of each weight selector switch of the plurality of weight selector switches therethrough as the stem is moved relative to the plurality of weights, and when the respective selector switch of the plurality of weight selector switches is positioned in a first position.

10. The exercise machine of claim 9 , wherein each weight of the plurality of weights comprises a channel extending from each at least one opening, the channel positioned to receive a respective lug of each weight selector switch of the plurality of weight selector switches therein and facilitate mechanical interference between the respective lug and the weight causing the weight to move with the stem when the stem is moved, and when the respective selector switch of the plurality of weight selector switches is positioned in a second position.

11. The exercise machine of claim 1 , wherein the stem is coupled to at least one cable.

12. The exercise machine of claim 1 , wherein the cap comprises at least one lug positioned and configured to selectively enter a corresponding channel in a corresponding weight of the plurality of weights.

13. The exercise machine of claim 12 , wherein a portion of the cap is positioned within a channel of the stem.

14. The exercise machine of claim 1 , wherein each weight selector switch of the plurality of weight selector switches comprises a split switch body, a first component of the split switch body having a portion thereof positioned within a channel of the stem, a second component of the split switch body coupled to the first component to lock the first component on the stem.

15. A method of manufacturing a weight selecting device, the method comprising:

providing a stem;

mounting a plurality of weight selector switches to the stem, each weight selector switch of the plurality of weight selector switches positioned and configured to selectively couple a corresponding weight of the plurality of weights to the stem;

positioning a sleeve with at least two detents onto the stem;

positioning a switch body onto the sleeve;

positioning a cap onto the switch body;

positioning a spring biased ball within the switch body; and

rotating the switch body and the cap to position a portion of the cap within a channel of the stem.

16. The method of claim 15 , wherein mounting each weight selector switch of the plurality of weight selector switches to the stem further comprises:

positioning a portion of a first component within a channel of the stem; and

coupling a second component to the first component.

17. A weight selecting device, comprising:

a stem; and

a plurality of weight selector switches mounted to the stem, each weight selector switch positioned and configured to selectively couple a corresponding weight of the plurality of weights to the stem;

wherein each weight selector switch of the plurality of weight selector switches includes a sleeve positioned on the stem, a switch body positioned on the sleeve, and a cap positioned on the switch body; and

wherein the sleeve includes at least two detents and a spring biased ball positioned within the switch body.
