Abstract
Abstract A device is disclosed and claimed herein for practice and instructional use in the proper technique for swinging a golf club. A pair of spaced apart, circular guide rails are provided and maintained in a particular relationship so as to define a complete circular swing path therebetween. The guide rails are maintained in the proper relationship by a plurality of spacer or connector elements secured thereto and positioned around the circle. Further, the guide rails are supported by a plurality of elements from the ground or other surface. A first support element may be provided that defines a starting point for the golf swing where a ball rests and may be properly addressed. Further, a shield may be provided on the first support element as a safety factor and also for display of instructional indicia. Further support is provided by a pair of adjustable rods that are received on the ground or other surface, the length of which may be varied so as to adjust the plane of the swing arc. Further embodiments of the present invention include a head movement indicator cord, variable size guide rails, and shock absorbing coverings around the upper portion of the swing arc.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
104 words
A golf swing practice and instructional device comprising: a. a first circular guide rail; b. a second circular guide rail positioned apart from said first guide rail a sufficient distance therefrom to receive a shaft of a golf club therebetween and in a plane substantially parallel thereto, said guide rails defining an unobstructed, endless circular swing path therebetween; c. a plurality of connector means secured to said first and second guide rails at spaced apart locations, said connector means maintaining said guide rails at a predetermined relation with respect to each other; and d. support means positioning said guide rails at a predetermined angle.
Claim 2
Dependent Claim
104 words
A golf swing practice and instructional device comprising: a. a first circular guide rail; b. a second circular guide rail positioned apart from said first guide rail a sufficient distance therefrom to receive a shaft of a golf club therebetween and in a plane substantially parallel thereto, said guide rails defining an unobstructed, endless circular swing path therebetween; c. a plurality of connector means secured to said first and second guide rails at spaced apart locations, said connector means maintaining said guide rails at a predetermined relation with respect to each other; and d. support means positioning said guide rails at a predetermined angle.
