Abstract

A weight plate having rotatable handles is disclosed. By rotating, the handles provide a sure grip to the user, while allowing the user to perform various exercises without adjusting his or her grip on the device. The handles also facilitate the safe loading and unloading of the device on plate-loaded exercise equipment. The weight plate may thus be used as a stand-alone exercise device, as a weight plate loaded onto a barbell or dumbbell bar, or as a weight plate used on plate-loaded exercise equipment.

Claims

1. An exercise device, comprising:

(a) a weighted plate comprising a circumference; and

(b) a straight handle attached to said plate, wherein said handle is rotatable with respect to said plate, said handle is rotatable about an axis lying in a common plane with said plate, and said handle is attached to said plate within said circumference of said plate.

2. The exercise device of claim 1, wherein said handle comprises:

(a) a hollow shaft; and

(b) a rod travelling coaxially through said shaft.

3. The exercise device of claim 1, wherein said weighted plate comprises a notch, said notch comprises two corners, and said handle comprises:

(a) a hollow shaft; and

(b) a rod extending coaxially through said shaft and through openings in the said corners of said notch in said plate.

4. The exercise device of claim 1, further comprising a resilient coating over said plate.

5. The exercise device of claim 4, wherein said resilient coating is rubber.

6. The exercise device of claim 1, further comprising an ergonomic grip that at least partially coats said handle.

7. The exercise device of claim 1, further comprising a second handle.

8. The exercise device of claim 7, wherein said second handle is attached to said plate at the side of said plate opposite to the location of said handle.

9. The exercise device of claim 8, wherein each of said handles comprises:

(a) a hollow shaft; and

(b) a rod extending coaxially through said shaft.

10. An exercise device comprising:

(a) a plate shaped as a disc with at least one notch, wherein said notch is large enough to accommodate the back of a users hand when the user grips the exercise device and rotates the hand into said notch; and

(b) a straight handle lying within said notch in a common plane with said plate, wherein said handle is rotatable with respect to said plate, and said handle is rotatable about an axis lying in said common plane.

11. The exercise device of claim 10, wherein said handle comprises:

(a) a hollow shaft; and

(b) a rod travelling coaxially through said shaft.

12. The exercise device of claim 11, wherein said rod has a first end and a second end, and said handle further comprises:

(a) two riders, one of said riders travelling coaxially along said first end of said rod and the other of said riders travelling coaxially along said second end of said rod; and

(b) a resilient member biasing each of said riders away from the other of said riders.

13. The exercise device of claim 12, wherein said resilient member is a spring mounted coaxially along said rod.

14. An exercise device, comprising:

(a) a weighted plate comprising a circumference; and

(b) a handle attached to said plate, wherein said handle is rotatable with respect to said plate, said handle is rotatable about an axis lying in a common plane with said plate, said handle is attached to said plate within said circumference of said plate, and wherein said handle comprises;

(i) a hollow shaft;

(ii) a rod travelling coaxially through said shaft, wherein said rod comprises a first end and a second end, and said handle further comprises two riders, one of said riders travelling coaxially along said first end of said rod and the other of said riders travelling coaxially along said second end of said rod; and

(iii) a resilient member biasing each of said riders away from the other of said riders.

15. The exercise device of claim 14, wherein said resilient member is a spring mounted coaxially along said rod.

16. An exercise device comprising:

(a) a plate shaped as a disc with at least one notch, wherein said notch is large enough to accommodate the back of a user'"'"'s hand when the user grips the exercise device and rotates the hand into said notch; and

(b) a handle lying within said notch in a common plane with said plate, wherein said handle is rotatable with respect to said plate, said handle is rotatable about an axis lying in said common plane, and wherein said handle comprises;

(i) a hollow shaft; and

(ii) a rod travelling coaxially through said shaft, wherein said rod has a first end and a second end, and said handle further comprises two riders, one of said riders travelling coaxially along said first end of said rod and the other of said riders travelling coaxially along said second end of said rod; and

(iii) a resilient member biasing each of said riders away from the other of said riders.

17. The exercise device of claim 16, wherein said resilient member is a spring mounted coaxially along said rod.
