Abstract

The combination with liftable apparatus, including at least one weight, includes an assembly comprising at least one generally upright guide or housing supported by a base to extend near at least one weight, at least one elongated cord extending in proximity to the guide, or within the housing, the cord being resiliently stretchable and having a lower end retained relative to the base, the cord having an upper end portion configured to be lifted with the weight, whereby when said assembly is lifted, the cord becomes resiliently stretched to resist such lifting. Multiple such cords can be provided to extend in parallel, and may be coded as by color, for cord selection to provide selected added resistance to weight lifting.

Claims

1. In combination with liftable apparatus, including at least one weight, an assembly comprising

a) a base, and at least one generally upright guide supported by the base to extend near said at least one weight,

b) multiple selectable cords extending upright in proximity to said at least one guide, said cords being resiliently stretchable and having lower ends retained relative to the base,

c) each cord having an upper end portion configured to be lifted with the weight,

d) whereby the selected cord becomes resiliently stretched to resist such lifting.

2. The assembly of claim 1 wherein said guide is a first upright housing, and said cord extends within the housing.

3. The assembly of claim 2 wherein said at least one weight comprises a stack of weights, and said housing extends adjacent the stack.

4. The assembly of claim 3 including wherein the guide includes a second upright housing, and a second resiliently stretchable cord extends within the second housing.

5. The assembly of claim 4 including multiple weights in a stack, and said upright housings are located proximate transversely spaced portions of said stack of weights.

6. The assembly of claim 1 wherein there are two of said upright guides and a cord adjacent each guide, said guides laterally spaced apart at opposite sides of the center of mass of said at least one weight.

7. The assembly of claim 1 including weight retention means at a location spaced from said guide, the selected cord being releasably attached to said means.

8. The assembly of claim 1 including at least one hook to support a selected cord upper end portion.

9. The combination of claim 8 wherein said hook is spaced above the level of the guide, and including retention means extending transversely at the upper-end of said at least one weight to support said hook.

10. The combination of claim 1 wherein each cord upper end portion is looped to be releasably attached to structure associated with a weight.

11. The combination of claim 10 wherein the cords have different stretch characteristics.

12. The combination of claim 1 wherein said cords have looping upper end portions to be selectively hung on structure associated with a weight, the cords being color coded.

13. In combination with liftable strength training apparatus, either incorporated in a machine, or as an attachment to an existing machine, where the machine has a movement resistance arm, including at least one weight, an assembly comprising

a) at least one generally upright guide supported by a base to extend near said at least one, weight or near said arm,

b) multiple upright cords extending in proximity to the guide or guides, each cord being resiliently stretchable and having a lower end retained relative to the base, for resisting lifting movement of said weight or arm,

c) each cord having an upper end portion spaced from the guide and configured to be lifted with the weight, or with said arm,

d) whereby the cord becomes resiliently stretched to resist such lifting or movement of said arm.

14. The assembly of claim 13 wherein the cord consists of one of the following:

i) rubber tubing

ii) an elastic band or bands.

15. The assembly of claim 13 wherein said guide is an upright housing, and said cords have lower portions that extend within the housing.

16. The assembly of claim 15 wherein said at least one weight comprises a stack of weights, and said housing extends adjacent the stack, or adjacent to said arm.

17. The assembly of claim 13 wherein there are at least two of said upright guides or cores adjacent to each guide, said guides laterally spaced apart at opposite sides of the center of mass of said at least one weight or arm.

19. The assembly of claim 16 wherein said cords extend in parallel relation there being hooks associated with the cords to support an upper end or ends defined by a selected cord or cords, for generally upward stretching.

20. The assembly of claim 16 wherein there are at least two of said cords extending in parallel relation, and having substantially equal length.

18. In combination with liftable apparatus, including at least one weight, an assembly comprising

a) a base, and at least one generally elongated guide supported by the base to extend near said at least one weight,

b) multiple selectable cords extending substantially upright in proximity to said at least one guide, said cords being resiliently stretchable upwardly as said at least one weight is lifted, and having lower ends retained relative to the base,

c) each cord having an upper end portion configured to be lifted with the weight,

d) whereby the selected cord becomes resiliently stretched to resist such lifting.
