Abstract
Abstract A golf swing training device comprised of a grip, a foreshortened shaft and a hollow head. The head contains a battery activated by a switch also located within the head, to illuminate a lamp, also within the head. The lamp emits a beam of light downward to the ground and forward of the club head. The light beam permits the golfer to trace the arc of light corresponding to the golfer's swing to impart a mental image to the golfer of the precise club head path. The device also comprises a linear guide strip which is placed on the ground in front of the golfer to establish the desired club head path. The golfer preferably follows the path of the light beam during a swing and compares the light path to the guide strip.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
210 words
A golf club training device to be used by a person comprising a shaft and a head simulating the appearance of a conventional golf club, said head having a front face, said shaft being foreshortened so that when said device is swung to simulate the driving of a golf ball, said head is spaced slightly off of the surface upon which said person using said device is standing, said head comprising a hollow body, containing self-contained electrical power source means, light generating means, and switch means, said light generating means being arranged for projecting a beam of light out of said head, said switch means being connected to said light generating means and said power source means for causing said light generating means to produce said beam of light from said electrical power source means, said light generating means being oriented with respect to said hollow body so that said beam of light is projected out of said head toward said surface and slightly forward of said front surface of said head, whereupon when said person swings said golf club training device, said person can freely see said beam of light projected in a path across said surface to enable said person to adjust said swing to a desired path.
