Abstract

A forearm mounted wrist position training device for signaling a golfer when his or her wrists bend improperly during a golf swing. A housing is secured to a forearm with a sensor pad engaging the back of the hand. The pad position can be varied to fit the forearm and wrist position when the golfer addresses the ball. The pad is mounted on one end of a sensor lever with an attachment device attached to the other. An actuator lever is fastened to the attachment device, with the other end pivotally mounted in the housing adjacent to a switch. When the golfer bends his or her wrist beyond a selected limit, the actuator lever will close the switch which will then activate a battery powered circuit to produce a signal such as an audible beep. The training device can be placed on either wrist and is useful with putters and other clubs. The golfer will learn to hold his wrists in the proper position by avoiding causing the signal to sound.

Claims

1. A wrist position training device for golfers which comprises:

a housing;

means for releasably securing said housing to a golfer'"'"'s forearm adjacent to a wrist;

a sensor lever for extending along said wrist to a golfers hand;

a pad pivotally mounted on a distal end of said sensor lever for engagement with said golfer'"'"'s hand;

attachment means secured to a proximal end of said sensor lever for allowing movement of said sensor lever with said golfer'"'"'s hand relative to said attachment means as said wrist is bent toward said sensor lever;

an actuator lever pivotally mounted in said housing and having a distal end secured to said attachment means;

a normally open switch means positioned adjacent to an actuator lever proximal end for actuation by said actuator lever; and

alarm means for producing a signal perceivable by said golfer when said switch is closed as said wrist is bent toward said sensor lever a predetermined distance.

2. The wrist position training device according to claim 1 wherein said pad is sized so that an edge of said pad will engage and move said attachment means to pivot said actuator lever when said wrist is bent toward said sensor lever said predetermined distance to cause said actuator lever proximal end to engage and close said switch.

3. The wrist position training device according to claim 1 wherein said means for releasably securing said housing to a golfer'"'"'s forearm comprises a band fastenably around said forearm and a clip on said housing for engaging said band.

4. The wrist position training device according to claim 3 wherein said band comprises hook-and-loop material for fastening said band around said forearm and said clip has an open end for slipping around said band while said band is on said forearm.

5. The wrist position training device according to claim 1 wherein said means for producing a perceivable signal comprises means for generating at least one audible beep.

6. The wrist position training device according to claim 1 wherein said attachment means and sensor lever have cooperating ridges on contacting surfaces so that said contacting surfaces will releasably hold said sensor lever in position relative to said attachment means until released by imposition of a predetermined force.

7. The wrist position training device according to claim 1 further including an elastic boot between said attachment means and said housing.

8. The wrist position training device according to claim 1 wherein said pad is mounted on said distal end of said sensor lever by a ball and socket connection allowing tilting of said pad in all directions over a predetermined range of motion.

9. A wrist position training device for golfers which comprises:

a housing;

means for releasably securing said housing to a golfer'"'"'s forearm adjacent to a wrist;

a sensor lever for extending along said wrist to a golfers hand;

a pad pivotally mounted on a distal end of said sensor lever for engagement with said golfer'"'"'s hand;

attachment means secured to a proximal end of said sensor lever for allowing movement of said sensor lever with said golfer'"'"'s hand relative to said attachment means as said wrist is bent toward said sensor lever;

a plurality of transverse ridges on contacting surfaces of said attachment means and said sensor lever for releasably holding the relative position of said contacting surfaces until subjected to a predetermined moving force;

an actuator lever pivotally mounted in said housing and having a distal end secured to said attachment means;

a normally open switch means positioned adjacent to an actuator lever proximal end for actuation by said actuator lever;

said pad being sized so that an edge of said pad will engage and move said attachment means to pivot said actuator lever when said wrist is bent toward said sensor lever said predetermined distance to cause said actuator lever proximal end to engage and close said switch; and

alarm means for producing an audible signal perceivable by said golfer when said switch is closed as said wrist is bent toward said sensor lever a predetermined distance.

10. The wrist position training device according to claim 9 wherein said means for releasably securing said housing to a golfer'"'"'s forearm comprises a band fastenably around said forearm and a clip on said housing for engaging said band.

11. The wrist position training device according to claim 10 wherein said band comprises hook-and-loop material for fastening said band around said forearm and said clip has an open end for slipping around said band while said band is on said forearm.

12. The wrist position training device according to claim 9 further including an elastic boot between said attachment means and said housing.

13. The wrist position training device according to claim 9 wherein said pad is mounted on said distal end of said sensor lever by a ball and socket connection allowing tilting of said pad in all directions over a predetermined range of motion.
