Abstract
Abstract Apparatus is disclosed for fixedly positioning an axis of the body relative to the ground while permitting rotational motion of the head about the fixed axis, including a telescoping pole for anchoring in the ground, a crossbar extending between the telescoping pole and the axis of the body to be fixed, an adjustable clutch for permitting proper angular positioning of the crossbar, a head cap and chin strap for rigidly securing about the head of the golfer, and a rotatable bearing for securing the head cap to the crossbar to limit motion in all directions except rotational motion about the fixed axis.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
228 words
A golf training device for affixing an axis of the body of a golfer relative to a preferred axis for constraining body motion to aid in the development of a consistent swing, comprising (a) a tubular pole having a first section adapted for insertion into the ground and having a second telescopic section extensibly fitted to said first section, said second section having a free end adapted for vertical projection (b) an adjustable toothed clutch attached to said second section free end, said clutch having a selectively rotatable member forming a part thereof; (c) a shaft having an end attached to said selectively rotatable member and having a second free end; (d) a rotatable coupling attached to said shaft second free end, said coupling permitting only rotational movement about a preferred axis normal to said shaft and parallel to the axis of the body of a golfer to be affixed relative to the preferred axis; and (e) a head cap attached to said rotatable coupling, said head cap having downwardly depending sides for tightly enclosing at least a portion of the head of a golfer and being adapted for tightly fitting over the head of a golfer, and said head cap having an adjustable chin strap adapted for securing about said head; whereby the head of a golfer is constrained to permit motion only about said preferred axis.
Claim 2
Dependent Claim
228 words
A golf training device for affixing an axis of the body of a golfer relative to a preferred axis for constraining body motion to aid in the development of a consistent swing, comprising (a) a tubular pole having a first section adapted for insertion into the ground and having a second telescopic section extensibly fitted to said first section, said second section having a free end adapted for vertical projection (b) an adjustable toothed clutch attached to said second section free end, said clutch having a selectively rotatable member forming a part thereof; (c) a shaft having an end attached to said selectively rotatable member and having a second free end; (d) a rotatable coupling attached to said shaft second free end, said coupling permitting only rotational movement about a preferred axis normal to said shaft and parallel to the axis of the body of a golfer to be affixed relative to the preferred axis; and (e) a head cap attached to said rotatable coupling, said head cap having downwardly depending sides for tightly enclosing at least a portion of the head of a golfer and being adapted for tightly fitting over the head of a golfer, and said head cap having an adjustable chin strap adapted for securing about said head; whereby the head of a golfer is constrained to permit motion only about said preferred axis.
Claim 3
Dependent Claim
23 words
The apparatus of claim 1, wherein said clutch further comprises two facing toothed members, one of said members forming said selectively rotatable member.
Claim 4
Dependent Claim
12 words
The apparatus of claim 2, wherein said shaft free end is flattened.
Claim 5
Dependent Claim
30 words
The apparatus of claim 3, wherein said rotatable coupling further comprises a first bearing plate secured against said flattened shaft, and a second bearing plate secured against said head cap.
Claim 6
Dependent Claim
27 words
The apparatus of claim 4, further comprising a hollow tubular member sized slightly larger than said tubular pole first section and having a pointed and closed end.
Claim 7
Dependent Claim
31 words
The apparatus of claim 5, wherein said tubular pole first section further comprises a frictional fitting attached to the end of said pole adapted for insertion into said hollow tubular member.
