Abstract
Abstract A device for detecting unwanted movement of a golfer''s head has a base which fixes to a golfer''s cap, and a pivotal arm extending from the base. The arm and base are interconnected by an adjustable spring, the tension of which holds the arm in a cocked position. However, when the golfer''s head is moved in an undesirable manner, the arm, through its own inertia, overcomes the spring tension holding it cocked, and the arm snaps over against the base.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
272 words
A device for aiding a golfer in keeping his head still while golfing comprising: a. a base adapted to be fixed relative to the golfer''s head; b. an arm mounted to the base and pivotable relative thereto about an axis in first and second directions; c. first stop means for limiting the movement of the arm relative to the base in the first direction at a first position; d. second stop means for limiting the movement of the arm relative to the base in the second direction at a second position; e. holding means for holding the arm from pivoting from said first position to said second position when the base is held relatively still; f. mean for permitting the inertia of the arm to overcome the holding force of said holding means in response to various movements being imparted to said device, said movements being of the type corresponding to undesired head movements of a golfer while executing a golf club swing, so that when attached to a golfer''s head, upon an improper head movement by a golfer while executing a club swing, said arm will move from said first position to said second position; and g. said holding means comprising a spring fixed to and interconnecting the base and arm under tension in such a manner that pivoting of the arm from the first position toward the second position increases the tension of the spring to a maximum when the arm reaches a predetermined position relative to the base, from which position tension of the spring aids the inertia of the arm to move the arm to the second position.
Claim 2
Independent Claim
272 words
A device for aiding a golfer in keeping his head still while golfing comprising: a. a base adapted to be fixed relative to the golfer''s head; b. an arm mounted to the base and pivotable relative thereto about an axis in first and second directions; c. first stop means for limiting the movement of the arm relative to the base in the first direction at a first position; d. second stop means for limiting the movement of the arm relative to the base in the second direction at a second position; e. holding means for holding the arm from pivoting from said first position to said second position when the base is held relatively still; f. mean for permitting the inertia of the arm to overcome the holding force of said holding means in response to various movements being imparted to said device, said movements being of the type corresponding to undesired head movements of a golfer while executing a golf club swing, so that when attached to a golfer''s head, upon an improper head movement by a golfer while executing a club swing, said arm will move from said first position to said second position; and g. said holding means comprising a spring fixed to and interconnecting the base and arm under tension in such a manner that pivoting of the arm from the first position toward the second position increases the tension of the spring to a maximum when the arm reaches a predetermined position relative to the base, from which position tension of the spring aids the inertia of the arm to move the arm to the second position.
Claim 3
Dependent Claim
40 words
A device according to claim 1 wherein are included means for varying the point at which the spring is fixed to the base, to vary the position of the arm relative to the base at which maximum spring tension occurs.
Claim 4
Dependent Claim
35 words
A device according to claim 2 wherein is further included means removably fixed to the arm positioned to move into the line of vision of the golfer when the arm is in the second position.
