Abstract

Components of a golf exerciser are contained within a tube that can be swung in a simulated golf swing independently of a golf club. Within the tube is an extension spring connected to a weight so that centrifugal force developed during swinging the tube can move the weight toward a distal end of the tube. There, a shock absorber is positioned for the weight to impact against whenever sufficient arcuate tube velocity is achieved. The shock absorber includes a deformable elastomer that cushions and stops the distal movement of the weight and also makes a sound indicating that a swing of sufficient velocity has been achieved.

Claims

1. A golf swing exerciser using a hollow tube having an anchorage in a handle end for an extendable elastomeric element connected to a weight arranged so that the weight can move toward a distal end of the tube in response to centrifugal force, and the elastomeric element can move the weight toward the handle end of the tube when the weight is not subjected to the centrifugal force, the golf swing exerciser comprising:

the hollow tube being independent of a golf club and not attached to a golf club;

the tube being sized to be swung in an arc simulating a swing of a golf club;

a shock absorber arranged within the tube at a distal end of the tube, the shock absorber including a deformable elastomer;

the weight and the shock absorber being disposed within the tube so that when the tube is swung at a sufficient velocity so that the weight extends the elastomeric element to move the weight to impact the shock absorber at a distal end of travel of the weight; and

the weight deforms the elastomer as the shock absorber brings distal movement of the weight to a stop.

2. The exerciser of claim 1 wherein the shock absorber includes a distal end plug, the deformable elastomer, and a screw and washer securing the deformable elastomer to the end plug.

3. The exerciser of claim 2 wherein a distal end of the weight is configured to engage the washer.

4. The exerciser of claim 1 wherein the elastomeric element is an extension spring and the weight has a helically grooved stem that is screwed into distal end convolutions of the extension spring in an interference fit that connects the weight to the spring.

5. The exerciser of claim 1 wherein the shock absorber includes a distal end plug secured to the tube by an assembly that extends through the plug and through diametrically opposite regions of a wall of the tube.

6. A golf swing exerciser including a hollow tube having a distal end stop, an extendable elastic element and a weight attached to the elastic element ;

within the tube so that a centrifugal force causes the weight to extend the elastic element and move toward the distal end of the tube, the exerciser comprising;

the tube being independent of a golf club and not attached to a golf club;

a shock absorber supported by the distal end stop;

the weight being arranged to impact the shock absorber; and

the shock absorber being arranged to deform elastomerically as it brings the distal movement of the weight to a cushioned stop.

7. The exerciser of claim 6 wherein the shock absorber includes a distal end plug, the deformable elastomer, and a screw and washer securing the deformable elastomer to the end plug.

8. The exerciser of claim 6 wherein the elastomeric element is an extension spring and the weight has a helically grooved stem that is screwed into distal end convolutions of the extension spring in an interference fit that connects the weight to the spring.

9. The exerciser of claim 6 wherein a distal end of the weight is configured to engage the washer.

10. A golf swing exerciser comprising:

a hollow tube having a length approximating a length of a golf club shaft;

the tube being independent of a golf club and not attached to a golf club;

the tube having a handle affording a grip for swinging the tube in an arc simulating a golf swing;

a distal end stop anchored in a distal end region of the tube;

the distal end stop including a shock absorber within the tube;

the shock absorber including a deformable elastomer;

an extendable elastomeric element secured to a handle end anchorage within the tube;

a weight secured to a distal end of the elastomeric element, the weight having a mass related to a length of the elastomeric element and a force of the elastomeric element so that when the tube is swung independently of a golf club in an arc simulating a golf club swing, centrifugal force applied to the weight overcomes the force of the elastomeric element and moves the weight toward the distal end of the tube; and

a distal end of the weight being configured to impact the shock absorber so that the deformable elastomer cushions and stops movement of the weight toward the distal end of the tube.

11. The exerciser of claim 10 wherein the exerciser has a golf club.

12. The exerciser of claim 10 wherein the elastomeric element is an extension spring and the weight has a helically grooved stem threadably received within distal convolutions of the extension spring for an interference fit retaining the weight on the spring.

13. The exerciser of claim 10 wherein the distal end stop anchorage includes a plug secured to a wall of the tube.

14. The exerciser of claim 13 wherein the distal end plug is secured to the tube by an assembly that extends through the plug and through diametrically opposite regions of a wall of the tube.
