Abstract
Abstract A golf practice and training device in which an outer end of an activating arm engages the forehead of a golfer and serves to trigger the withdrawal of a simulated ball out of the path of a club head in response to excessive movement of the golfer''s head during execution of the golf swing. In one embodiment, movement of the ball is triggered mechanically when a detent mechanism is displaced by movement of the activating arm. In another embodiment, the ball is withdrawn upon the energization of an electric solenoid which is actuated in response to axial movements of the actuating arm.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
143 words
A golf training and practice device comprising a supporting structure, an actuating arm, means mounting said arm on said supporting structure for movement in directions toward and away from the head of a golfer standing in a golfing position opposite said supporting structure, means biasing said arm into engagement with the golfer''s head, a member representing a simulated golf ball target, means supporting said target member on said supporting structure for movement between a first position wherein it is in a position to be struck by the golfer with a golf club and a second position wherein it is withdrawn away from the path of the golf club, and actuating means connecting said arm and the last-mentioned target member supporting means, said actuating means being responsive to movement of said arm to move said target member from said first to said second position.
Claim 2
Dependent Claim
143 words
A golf training and practice device comprising a supporting structure, an actuating arm, means mounting said arm on said supporting structure for movement in directions toward and away from the head of a golfer standing in a golfing position opposite said supporting structure, means biasing said arm into engagement with the golfer''s head, a member representing a simulated golf ball target, means supporting said target member on said supporting structure for movement between a first position wherein it is in a position to be struck by the golfer with a golf club and a second position wherein it is withdrawn away from the path of the golf club, and actuating means connecting said arm and the last-mentioned target member supporting means, said actuating means being responsive to movement of said arm to move said target member from said first to said second position.
Claim 3
Dependent Claim
100 words
A device according to claim 1, wherein said target member supporting means includes means biasing said target member toward said second position, and said actuating means includes a mechanical detent mechanism adapted to be cocked to maintain said target member in said first position against the force of the last-mentioned biasing means, said actuating arm being connected to said detent mechanism and operable to uncock the same in response to movement of the actuating arm due to forward or backward movement of the golfer''s head, thereby to effect release of said target member and movement thereof to said second position.
Claim 4
Dependent Claim
43 words
A device according to claim 1, wherein said actuating means comprises an electrical energizing circuit, an electrically actuated means for moving said target member, and switching means responsive to movement of said activating arm to energize said electrically actuated means through said circuit.
Claim 5
Dependent Claim
24 words
A device according to claim 3, wherein said electrically actuated means comprises a solenoid operatively connected between said actuating arm and said target member.
Claim 6
Dependent Claim
33 words
A device according to claim 1, wherein said actuating arm extends upwardly and outwardly from said first-mentioned supporting means and has an outer free end positioned to engage the forehead of the golfer.
Claim 7
Dependent Claim
75 words
A device according to claim 5, wherein said actuating means comprises a mechanical detent mechanism adapted to be cocked to retain said target member in said first position, said actuating arm being connected to said detent mechanism and operable to uncock the same in response to movement of the actuating arm due to forward or backward movement of the golfer''s head during the golf swing, thereby to move said target member to said second position.
