Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
138 words
A golf swing monitor to audibly signal improper head movement during a golf swing comprising a compact, integrated housing including a battery, an on-off switch, a signal buzzer and a motion sensing switch all connected in a series circuit, a golf cap including a visor, a crown, and a front crown panel extending above the visor, first support means medially located on the inside surface of said front crown panel, second support means on an exterior surface of said housing, said second support means being attached to said first support means in a predetermined angular position whereby when said golf cap is worn by a golfer during a golf swing and said on-off switch is in an on position, the buzzer will sound on the occurrence of any improper head movement as sensed by said motion sensing switch.
Claim 2
Dependent Claim
138 words
