Abstract

A weight system includes a selector which is movable along weights and may be inserted into a void between adjacent weights.

Claims

1. A weight system comprising:

a vertically movable weight lift;

weights;

at least one selector having an opening and rotatable to selectively couple one or more weight to the weight lift, wherein the weights include vertically aligned channels through which the selector moves along the weights; and

a stem coupled to the weight lift and slidably supporting the selector along a first axis, the stem comprising a plurality of alternating segments and spacers along the first axis,

wherein the selector is rotatable about the first axis of the stem between a first angular position in which the selector is slidable along the first axis and a second angular position in which the selector is retained along the first axis relative to the stem; and

wherein each segment having a cross-sectional shape configured such that each segment may pass through the opening when the selector is in the first angular position about the first axis and ma not sass through the opening when the selector is in the second angular position about the first axis.

2. The weight system of claim 1, wherein the selector includes a tubular portion completely surrounding the segments and spacers.

3. The weight system of claim 1, wherein adjacent weights form lower and upper faces in abutment and wherein the lower face includes a void configured to receive a portion of the selector.

4. The weight system of claim 1, wherein the selector includes a first projection and a second projection and wherein the first projection and the second projection extend into opposite voids when the selector is in the second angular position.

5. The weight system of claim 1, wherein adjacent weights are at least partially separated by voids horizontally across from one another.

6. The weight system of claim 1, wherein weights includes an upper weight having a lower surface and a lower weight having upper surface opposite to lower surface and wherein a majority of the upper surface and a lower surface are separated by one of the voids.

7. The weight system of claim 1 further comprising:

a guide rod extending through the weights; and

a bushing between each weight, each bushing slidably guiding movement of the weight along the rod and spacing one of the weights from a consecutive weight to form one of the voids.

8. The weight system of claim 1 further comprising:

a first incremental weight vertically extending across at least two of the weights; and

a second selector configured to selectively couple the incremental weight to the weight lift.

9. The weight system of claim 8, wherein the second selector rotates between a first position in which the first incremental weight is coupled to the weight lift and a second decoupled position.

10. The weight system of claim 8, wherein the first incremental weight comprises a rod extending through the weights.

11. The weight system of claim 8, further comprising a second incremental weight vertically extending across at least two of the weights, wherein the second selector is configured to selectively couple the second incremental weight to the weight lift.

12. The weight system of claim 1 further comprising a resiliently biased projection coupled to the selector and configured to resiliently project into the voids and out of the voids as the selector is slid along the weights.

13. The weight system of claim 1 further comprising:

a rod coupled to the weight lift and slidably supporting the selector, the rod including a plurality of axial spaces; and

a resiliently biased projection coupled to the selector and configured to resiliently project into spaces and out of the spaces as the selector is slid along the weights.

14. The weight system of claim 1, wherein the selector is configured to generate an audible sound as the selector is moved between the voids.

15. The weight system of claim 1, wherein each of the spacers has a circular cross-sectional shape concentrically extending about the first axis and guides rotation of the at least one selector about the first axis.

16. The weight system of claim 1, wherein the opening has a non-circular cross-sectional shape, wherein each of the segments as the non-circular cross-sectional shape and wherein the non-circular cross-sectional shape of the opening is aligned with non-circular cross-sectional shape of the segments when the selector is in the first angular position.

17. The weight system of claim 1, wherein the stem includes a first intersegmental gap on a first side of the first axis and a second intersegmental gap on a second opposite side of the first axis.

18. The weight system of claim 1, wherein the spacers extend a first radial distance from the first axis and wherein the segments extend a second radial distance from the first axis greater than the first radial distance.

19. A weight system comprising:

a vertically movable weight lift;

weights at least partially separated by voids horizontally across from one another;

at least one selector having an opening and rotatable to selectively couple one or more weight to the weight lift,

a stem coupled to the weight lift and slidably supporting the selector along a first axis, the stem comprising a plurality of alternating segments and spacers along the first axis,

wherein the selector is rotatable about the first axis of the stem between a first angular position in which the selector is slidable along the first axis and a second angular position in which the selector is retained along the first axis relative to the stem;

wherein each segment having a cross-sectional shape configured such that each segment may pass through the opening when the selector is in the first angular position about the first axis and may not pass through the opening when the selector is in the second angular position about the first axis; and

wherein the selector includes a first projection and a second projection and wherein the first projection and the second projection extend into opposite voids when the selector is in the second angular position.

20. A weight system comprising:

a vertically movable weight lift;

weights;

at least one selector having an opening and rotatable to selectively couple one or more weight to the weight lift,

a stem coupled to the weight lift and slidably supporting the selector along a first axis, the stem comprising a plurality of alternating segments and spacers along the first axis;

a first incremental weight vertically extending across at least two of the weights, wherein the first incremental weight comprises a rod extending through the weights; and

a second selector configured to selectively couple the incremental weight to the weight lift;

wherein the selector is rotatable about the first axis of the stem between a first angular position in which the selector is slidable along the first axis and a second angular position in which the selector is retained along the first axis relative to the stem; and

wherein each segment having a cross-sectional shape configured such that each segment may pass through the opening when the selector is in the first angular position about the first axis and may not pass through the opening when the selector is in the second angular position about the first axis.
