Abstract

A golf muscle weight training apparatus for attachment to the shaft of a golf club or other sports implement includes a weight carrier having an elongated weight supporting portion, a weight, and a clamp mechanism. The clamp mechanism cooperates with the weight carrier to clamp the weight carrier to the shaft with the axis of the weight supporting portion extending substantially perpendicular to a plane extending through the axis of the shaft and being offset laterally with respect to the axis of the golf club. The weight supporting portion supports a weight mass, with the weight mass extending in overlying relation with the head of the golf club. In another embodiment, the axis of the weight mass extends perpendicular to the axis of the golf club shaft. One or more extension weights can be coupled to the weight carrier to increase the weight mass of the weight training apparatus.

Claims

1. A weight training apparatus for attachment to an elongated shaft of a sports implement, the weight training apparatus comprising:

a weight carrier including a weight supporting portion;

a clamp mechanism including a clamp member cooperating with the weight carrier to define an opening for receiving the shaft, the clamp mechanism including at least one securing member for securing the clamp member to the weight carrier, the securing member including a shaft received by the weight carrier and cooperating with the weight carrier and the clamp member to removably secure the clamp member to the weight carrier;

at least one weight supported by the weight supporting portion; and

a bias spring located between opposing surfaces of the weight carrier and the clamp member, urging apart the weight carrier and the clamping member when the securing member is moved toward a release position.

2. The weight training apparatus according to claim 1, including a further weight supported by one of the weight supporting portion and the at least one weight.

3. The weight training apparatus according to claim 1, wherein the weight supporting portion comprises a support shaft, the at least one weight being supported on the support shaft.

4. The weight training apparatus according to claim 1, wherein the weight supporting portion includes a cavity for containing the at least one weight.

5. The weight training apparatus according to claim 4, wherein the at least one weight comprises weight ballast material filling the cavity.

6. The weight training apparatus according to claim 1, wherein one of the weight supporting portion and the at least one weight includes a threaded shaft and the other one of the weight supporting portion and the at least one weight includes a threaded opening for receiving the threaded shaft for coupling the at least one weight to the weight supporting portion.

7. The weight training apparatus according to claim 1, including an extension weight, adapted to be coupled to the weight supporting portion.

8. The weight training apparatus according to claim 1, wherein at least one of the weight supporting portion and the clamp member defines a lead-in portion for guiding the shaft into the opening during attachment of the weight training apparatus to the shaft.

9. The weight training apparatus according to claim 1, further including at least one anti-rotation member extending between the weight carrier and the clamp member for preventing relative rotation between the weight carrier and the clamp member.

10. The weight training apparatus according to claim 1, wherein the weight carrier includes a body portion that is generally cylindrical in shape.

11. The weight training apparatus according to claim 1, and including at least one extension weight coupled to the body portion and projecting outwardly therefrom.

12. The weight training apparatus according to claim 1, wherein the body portion includes at least one cavity for containing the at least one weight.

13. The weight training apparatus according to claim 1, wherein the bias structure includes a spring interposed between the weight carrier and the clamp member.

14. The weight training apparatus according to claim 1, wherein the weight carrier further includes a clamping portion having a first clamping surface, the clamp member having a second clamping surface opposing the first clamping surface and cooperating with the first clamping surface to define said opening for receiving the shaft, and wherein the at least one securing member secures the clamp member to the clamping portion of the weight carrier.

15. The weight training apparatus according to claim 14, including a first shaft gripping member of a resilient material extending along the first clamping surface and a second shaft gripping member of a resilient material extending along the second clamping surface.

16. A weight training apparatus for attachment to the shaft of a golf club, the golf club having a club head, the weight training apparatus comprising:

at least one weight;

a weight support assembly for coupling the at least one weight to the shaft, the weight support assembly including a weight carrier and a clamp member;

the weight carrier including a hollow body portion, the body portion being generally cylindrical in shape and having a first clamping surface, the clamp member having a second clamping surface opposing the first clamping surface, the first and second clamping surfaces defining an opening for receiving the shaft, and at least one securing member for securing the clamp member to the body portion, wherein the hollow body portion defines at least one cavity for containing the at least one weight.

17. The weight training apparatus according to claim 16, including a further weight, the further weight being coupled to and supported by the at least one weight.

18. The weight training apparatus according to claim 16, wherein the weight carrier includes a body portion, the body portion being generally cylindrical in shape and having a first clamping surface, the clamp member having a second clamping surface opposing the first clamping surface, the first and second clamping surfaces defining an opening for receiving the shaft, and at least one securing member for securing the clamp member to the body portion.

19. The weight training apparatus according to claim 18, wherein the body portion includes at least one cavity for containing the at least one weight.

20. The weight training apparatus according to claim 16, wherein the clamp member and the weight carrier include respective first and second opposing faces having respective first and second grooves which cooperate to define a shaft location opening, the first and second grooves being symmetrical and in-line within the first and second faces.

21. The weight training apparatus according to claim 16, including a further weight, and wherein the body portion includes a further cavity for containing the further weight.
