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 weight lift;

weights, at least portions of which are separated by voids; and

a first selector coupled to the weight lift and movably supported along a first axis along the weights, the selector being movable between an inserted position in a selected one of the voids and a withdrawn position;

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

a second selector configured to selectively couple the first incremental weight to the weight lift, wherein the first incremental weight comprises a rod extending through the weights.

2. The weight system of claim 1 further comprising a rod coupled to the weight lift and slidably supporting the selector.

3. The weight system of claim 2 further comprising a base including a bore, wherein the rod has an at least partially conical end removably received within the bore.

4. The weight system of claim 2, wherein the selector is rotatable about an axis of the rod between a first angular position in which the selector is slidable along the axis and a second angular position in which the selector is retained along the axis relative to the rod.

5. The weight system of claim 2, wherein the selector is slidable along a second axis perpendicular to the first axis between a first position in which the selector is slidably retained along the first axis relative to the rod and a second position in which the selector is movable along the first axis relative to the rod.

6. The weight system of claim 2, wherein the rod includes a plurality of axially spaced segments.

7. The weight system of claim 2, wherein the selector includes a tubular portion at least surrounding the rod by greater than or equal to about 180 degrees.

8. The weight system of claim 1 further comprising a stem extending along the first axis and coupled to the weight lift and including spaced segments axially joined by spacers and wherein the selector includes spaced prongs rotatable about the axis and the spacers to a position between the segments.

9. The weight system of claim 1, wherein the weights include aligned channels adjacent the voids through which the selector moves along the weights.

10. 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 portions of a void when the selector is in the inserted position.

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

12. 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.

13. 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.

14. The weight system of claim 1, 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 in which the first incremental weight is decoupled to the weight lift.

15. The weight system of claim 1, 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.

16. 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.

17. 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.

18. The weight system of claim 1, wherein each void comprises a space which is empty except when receiving the first selector.
