Abstract

A golf exerciser in the form of a swingable tube containing a movable mass supported by an extension spring is provided with a shock absorber cooperating with a proximal end mount for the spring. This absorbs recoil movement of the mass, the spring, the connector, and reduces recoil impact shock that otherwise could be felt by the hands of the person exercising.

Claims

1. In a golf swing exerciser that centrifugally moves a weight against resistance of an extension spring during a simulated golf swing, an improvement comprising:

a connector fixed to a proximal end of the extension spring;

a proximal end stop spaced from the connector;

a mount extending from the end stop to the connector, the mount allowing the connector to move toward the end stop and limiting motion of the connector away from the end stop; and

a resilient shock absorber arranged between the connector and the stop so that the shock absorber cushions a recoil of the weight and the spring when a simulated golf swing is stopped.

2. The golf swing exerciser of claim 1 wherein the mount supports the shock absorber.

3. The golf swing exerciser of claim 1 wherein the connector engages insides of terminal convolutions of the spring.

4. The golf swing exerciser of claim 1 wherein the connector is a bolt allowing the connector to slide toward and away from the end stop.

5. An exercising device used in a simulated golf swing, the device including an extension spring mounted to resist movement of a weight toward a distal end of the device during the golf swing, the device comprising:

a recoil stop;

a spring connector secured to a proximal end of the spring;

a mount supporting the spring connector to limit motion of the spring connector toward and away from the stop; and

a resilient shock absorber disposed between the stop and the spring connector so that the shock absorber cushions a recoil of the spring and the weight toward the stop.

6. The exercising device of claim 5 wherein the mount limits movement of the spring connector away from the stop, and allows movement of the spring connector toward the stop.

7. The exercising device of claim 6 wherein the connector is a bolt extending from the stop, and the connector is slidably mounted on the bolt.

8. The exercising device of claim 5 wherein the shock absorber is supported by the mount.

9. The exercising device of claim 8 wherein the mount is a bolt and the bolt extends through the shock absorber.

10. A golf exerciser that is moved in a simulated golf swing and includes a handle, and end stops in a proximal region of the handle, an extension spring mounted to extend toward a distal end of the exerciser, a weight attached to a distal end of the spring, and the spring and weight being configured so that the weight moves toward the distal end of the exerciser when the exerciser is moved in a simulated golf swing, the exerciser comprising:

a connector for a proximal end of the spring;

a lost motion mount extending from the end stop to the connector and supporting the connector for limited movement toward and away from the end stop; and

a resilient recoil shock absorber supported by the mount and arranged between the end stop and the spring connector so that the shock absorber cushions recoil movement of the weight, the spring, and the spring connector toward the end stop.

11. The golf exerciser of claim 10 wherein the mount is a bolt extending from the end stop, and the spring connector is slidably mounted on the bolt.

12. The golf exerciser of claim 11 wherein the bolt extends through the shock absorber.

13. The golf exerciser of claim 10 wherein the spring connector engages the insides of terminal coils of the proximal end of the spring.
