Abstract

Various embodiments of the present invention are directed to a multi-grip dumbbell. In one embodiment of the present invention, a multi-grip dumbbell includes a central handle, a first weighted head interconnected to the central handle in proximity to a first end of the central handle, and a second weighted head interconnected to the central handle in proximity to a second end of the central handle. The first weighted head is approximately evenly weighted with the second weighted head. The first weighted head includes a first weighted end handle and two weighted side handles. Similarly, the second weighted head includes a second weighted end handle and two weighted side handles.

Claims

1. A multi-grip dumbbell comprising:

a central handle having a first end and a second end;

a first weighted head interconnected to the central handle in proximity to the first end of the central handle, the first weighted head including a first weighted end handle, a first weighted side handle, and a second weighted side handle; and

a second weighted head of approximately equal shape and weight to the first weighted head, the second weighted head interconnected to the central handle in proximity to the second end of the central handle, the second weighted head including a second weighted end handle, a third weighted side handle, and a fourth weighted side handle.

2. The multi-grip dumbbell of claim 1 wherein the first weighted head and the second weighted head are each substantially planar.

3. The multi-grip dumbbell of claim 1 wherein the first weighted head and the second weighted head are each disc-shaped.

4. The multi-grip dumbbell of claim 3 wherein the first weighted end handle and the second weighted end handle each have two oppositely-positioned arc-shaped ends.

5. The multi-grip dumbbell of claim 4 wherein the first weighted side handle, the second weighted side handle, the third weighted side handle, and the fourth weighted side handle are each arc-shaped.

6. The multi-grip dumbbell of claim 5 wherein the first weighted side handle and the second weighted side handle are in proximity to opposite sides of the first weighted head.

7. The multi-grip dumbbell of claim 6 wherein the first weighted side handle, the second weighted side handle, and the two arc-shaped ends of the first weighted end handle collectively create the disc shape of the first weighted head.

8. The multi-grip dumbbell of claim 5 wherein the third weighted side handle and the fourth weighted side handle are in proximity to opposite sides of the second weighted head.

9. The multi-grip dumbbell of claim 8 wherein the third weighted side handle, the fourth weighted side handle, and the two arc-shaped ends of the second weighted end handle collectively create the disc shape of the second weighted head.

10. The multi-grip dumbbell of claim 1 wherein the first weighted side handle, the second weighted side handle, the third weighted side handle, and the fourth weighted side handle each have a circumference that is one or more of

round;

oval-shaped; and

U-shaped.

11. The multi-grip dumbbell of claim 1 wherein the central handle is one or more of

knurled;

and

tapered.

12. The multi-grip dumbbell of claim 1 wherein one or more of the weighted side handles are one or more of

knurled;

and

tapered.

13. The multi-grip dumbbell of claim 1 wherein one or more of the weighted end handles are one or more of

knurled;

and

tapered.

14. The multi-grip dumbbell of claim 1 wherein the central handle is attached to the first weighted head and to the second weighted head by one or more of

pressing a portion of the first end of the central handle into a recess in proximity to the center of an inner surface of the first weighted head and a portion of the second end into a recess in proximity to the center of an inner surface of the second weighted head;

welding the first end of the central handle in proximity to the center of an inner surface of the first weighted head and the second end in proximity to the center of an inner surface of the second weighted head;

screwing the first end of the central handle in proximity to the center of an inner surface of the first weighted head and the second end in proximity to the center of an inner surface of the second weighted head; and

bolting the first end of the central handle in proximity to the center of an inner surface of the first weighted head and the second end in proximity to the center of an inner surface of the second weighted head.

15. The multi-grip dumbbell of claim 1 wherein the first weighted side handle, the second weighted side handle, and the first weighted end handle are a unitary structure.

16. The multi-grip dumbbell of claim 1 wherein the first weighted side handle and the second weighted side handle are attached to the first weighted end handle by one or more of

pressing a portion of the first weighted side handle into a first recess in the first weighted end handle and pressing a portion of the second weighted side handle into a second recess in the first weighted end handle;

welding the first weighted side handle and the second weighted side handle to the first weighted end handle;

bolting the first weighted side handle and the second weighted side handle to the first weighted end handle; and

using epoxy to affix the first weighted side handle and the second weighted side handle to the first weighted end handle.

17. The multi-grip dumbbell of claim 1 wherein the third weighted side handle, the fourth weighted side handle, and the second weighted end handle are a unitary structure.

18. The multi-grip dumbbell of claim 1 wherein the third weighted side handle and the fourth weighted side handle are attached to the second weighted end handle by one or more of

pressing a portion of the third weighted side handle into a first recess in the second weighted end handle and pressing a portion of the fourth weighted side handle into a second recess in the second weighted end handle;

welding the third weighted side handle and the fourth weighted side handle to the second weighted end handle;

bolting the third weighted side handle and the fourth weighted side handle to the second weighted end handle; and

using epoxy to affix the third weighted side handle and the fourth weighted side handle to the second weighted end handle.

19. The multi-grip dumbbell of claim 1 wherein the first weighted end handle and the second weighted end handle are coated with one or more of

rubber;

polyurethane;

plastic;

chrome plating;

non-chip paint; and

neoprene.

20. The multi-grip dumbbell of claim 1 wherein the multi-grip dumbbell is fabricated from one or of

steel;

cast iron;

urethane;

plastic;

foam;

chrome; and

one or more vanity materials.
