Abstract
Abstract A golf training device and more particularly to a training device for improving ones skills in putting a golf ball including a reel assembly having one or more reel members each having a plurality of axially spaced, annular disc-like elements which provide a line-contact for maximizing the tracking action of the putter head during the putting stroke.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
172 words
A training device of the type adapted for use for putting a golf ball, said device including a putting head and which mounts a shaft adapted to carry a handle for putting the golf ball, said putter head including an elongated cavity which opens onto the bottom surface thereof, a reel assembly including a reel member disposed for rotational movement within said cavity, said reel member including a plurality of axially spaced disc elements having ground engaging surfaces, each of said disc elements including a substantially circular body having tapered side surfaces which extend outwardly and inwardly so as to imerge into a peripheral apex edge surface adapted for a substantially line-contact tracking action with the putting surface, said disc elements being defined also by unitary, radial spacer members which provide generally inverted, frusto-conical grooves between adjacent of said disc members, with said peripheral apex edge giving a line-contact across the putting surface to maximize the tracking ability of the putter head to insure a straight in-line back and forward putting stroke.
Claim 2
Dependent Claim
172 words
A training device of the type adapted for use for putting a golf ball, said device including a putting head and which mounts a shaft adapted to carry a handle for putting the golf ball, said putter head including an elongated cavity which opens onto the bottom surface thereof, a reel assembly including a reel member disposed for rotational movement within said cavity, said reel member including a plurality of axially spaced disc elements having ground engaging surfaces, each of said disc elements including a substantially circular body having tapered side surfaces which extend outwardly and inwardly so as to imerge into a peripheral apex edge surface adapted for a substantially line-contact tracking action with the putting surface, said disc elements being defined also by unitary, radial spacer members which provide generally inverted, frusto-conical grooves between adjacent of said disc members, with said peripheral apex edge giving a line-contact across the putting surface to maximize the tracking ability of the putter head to insure a straight in-line back and forward putting stroke.
Claim 3
Dependent Claim
58 words
A training device in accordance with claim 1, including a pair of laterally spaced parallel reel members, said reel members being mounted on a bracket means, and said bracket means being mounted for pivotal movement about a horizontal axis to enable the putter head to maintain a substantially straight tracking action upon encountering undulations in the putting surface.
Claim 4
Dependent Claim
63 words
A training device in accordance with claim 2, wherein said reel members each include a plurality of axially aligned, laterally spaced disc elements, said disc elements being of a symmetrical construction and each including a substantially circular body having tapered side surfaces which define an apex edge to give a substantially line-contact during tracking movement of the putter head across the putting surface.
Claim 5
Dependent Claim
62 words
A training device in accordance with claim 1, wherein said reel member is detachably carried by resilient snap-action retainer elements mounted within said cavity for resilient insertion and removal from said cavity, and a cover member adapted to be resiliently innerlocked over said cavity upon removal of said reel member when said putter is not to be used as a training device.
Claim 6
Dependent Claim
47 words
A training device in accordance with claim 1, wherein said disc elements are of a generally conical configuration with the end disc elements being of a half-disc construction so as to rotatably slide relative to the confronting interior surface provided by the cavity in said putter head.
Claim 7
Dependent Claim
35 words
A training device in accordance with claim 5, wherein said disc elements extend downwardly approximately one-fourth the diameter of the disc elements so as to be exposed below the bottom surface of said putter head.
