Abstract
Abstract A golf training and practice device for instructing a golfer to maintain his head in a fixed position during his golf swing is provided. The golf training and practice device comprises a headpiece for wear by a golfer using the training device, a support, and an electromagnet mounted on the support for releasably engaging a magnetic plate on the headpiece to hold the head of the golfer in a predetermined position and to indicate undesirable head movement during his golf swing. Either the magnetic plate or the electromagnet may be rotatably mounted to permit rotation of the golfer''s head. Suitable electrical components may be provided so that (1) the electromagnet will be energized in response to the weight of a golf ball on a golf tee, and (2) the electromagnet will be de-energized upon displacement of the golf ball from the tee.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
94 words
A golf training and practice device, comprising: a headpiece for wear by a golfer using the training device; a support; and means mounted on said support for lockingly and releasably engaging said headpiece to hold the head of the golfer in a predetermined position and to indicate undesirable head movement during his golf swing, the characteristics of said headpiece and said locking engagement being such as to permit said locking engagement to be released upon said headpiece being pulled away from the device without undue force in response to movement of the golfer''s head.
Claim 2
Dependent Claim
94 words
A golf training and practice device, comprising: a headpiece for wear by a golfer using the training device; a support; and means mounted on said support for lockingly and releasably engaging said headpiece to hold the head of the golfer in a predetermined position and to indicate undesirable head movement during his golf swing, the characteristics of said headpiece and said locking engagement being such as to permit said locking engagement to be released upon said headpiece being pulled away from the device without undue force in response to movement of the golfer''s head.
Claim 3
Dependent Claim
36 words
The golf training and practice device of claim 1, wherein: said headpiece includes an element of magnetic material; and said means for lockingly and releasably engaging said headpiece comprises a magnet for engagement with said element.
Claim 4
Dependent Claim
44 words
The gold training and practice device of claim 2, wherein said support includes: a base; a support column extending upward from said base; and an adjusting mechanism mounted on said support column for supporting said magnet in an adjustable position relative to said base.
Claim 5
Dependent Claim
32 words
The golf training and practice device of claim 3, which includes: a swivel device coupling said magnet to said adjusting mechanism to permit rotation of said magnet relative to said adjusting mechanism.
Claim 6
Dependent Claim
44 words
The golf training and practice device of claim 2, wherein: said headpiece comprises a headband including a strap of non-magnetic material extending between opposite sides of said headband; and said element of magnetic material comprises a plate of magnetic material mounted on said strap.
Claim 7
Dependent Claim
35 words
The golf training and practice device of claim 5, wherein said plate of magnetic material includes a raised edge extending around its periphery for preventing said magnet from sliding off the edge of said plate.
