Abstract
Abstract A golf training device for indicating a predetermined desired shifting of the weight of a golfer during a golf stroke, wherein a member is clamped to the sole of a shoe at the instep and mounts a spring plate extending laterally from the shoe and mounting at its outer end a ground engaging member. The spring has a deformed portion intermediate its length which produces an audible signal when a predetermined flexure of the spring plate occurs incident to a change of the angular position of the shoe as a proper or desired golf stroke is nearing completion.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
150 words
A golf training device comprising an elongated base, means for securing said base to the instep portion of a shoe to extend transversely of the shoe, an elongated spring plate projecting from said base longitudinally of said base, and laterally outwardly from the shoe, and an abutment part at the outer end of said spring plate spaced from the base and from the shoe for engagement with a surface on which a wearer of the shoe stands when the shoe tilts sidewise relative to said surface in the direction in which said spring plate extends, said spring plate including a deformed portion between said base and said abutment, said plate being adapted to produce a sound only incident to a predetermined extent of flexure of said spring plate during change of the lateral angular tilted position of the shoe incident of shifting of the wearer's weight during a golf stroke.
Claim 2
Dependent Claim
150 words
A golf training device comprising an elongated base, means for securing said base to the instep portion of a shoe to extend transversely of the shoe, an elongated spring plate projecting from said base longitudinally of said base, and laterally outwardly from the shoe, and an abutment part at the outer end of said spring plate spaced from the base and from the shoe for engagement with a surface on which a wearer of the shoe stands when the shoe tilts sidewise relative to said surface in the direction in which said spring plate extends, said spring plate including a deformed portion between said base and said abutment, said plate being adapted to produce a sound only incident to a predetermined extent of flexure of said spring plate during change of the lateral angular tilted position of the shoe incident of shifting of the wearer's weight during a golf stroke.
Claim 3
Dependent Claim
37 words
A golf training device as defined in claim 1, wherein said securing means includes a sole-engaging clamp fixed on said base and a sole-engaging clamp adjustable on said base and means for selectively positioning said adjustable clamp.
Claim 4
Dependent Claim
21 words
A golf training device as defined in claim 1, wherein said abutment member is longitudinally adjustably positioned on said spring plate.
Claim 5
Dependent Claim
44 words
A golf training device as defined in claim 1, wherein said securing means includes a fixed clamp member secured by said base and said spring is anchored at one end thereof between said base and clamp by securing means connecting said base and clamp.
Claim 6
Dependent Claim
45 words
A golf training device as defined in claim 1, wherein said base has an elongated guide portion, said securing means includes a clamp slidable on said base along said guide portion, and means carried by said base for urging said slidable clamp to clamping position.
Claim 7
Dependent Claim
26 words
A golf training device as defined in claim 1, wherein said deformed portion is positioned in spaced relation to the side edges of said spring plate.
Claim 8
Dependent Claim
26 words
A golf training device as defined in claim 1, wherein said deformed portion is substantially concavo-convex and spaced from the side edges of the spring plate.
