Abstract

A swing training device usable by a golfer comprises an elongated lightweight shaft adapted to be swung by a golfer to produce either a desirable accelerated or insufficiently accelerated swing, corresponding respectively to a desirably or insufficiently accelerated swing of a golf club, relative to a golf ball; and sound producing structure associated with the shaft to produce a distinctive audible sound when the shaft is swung so as to define a desirably accelerated swing.

Claims

1. In a swing training device usable by a golfer, the combination comprising

(a) an axially elongated lightweight tubular shaft adapted to be swung by a golfer to produce either a desirably accelerated or insufficiently accelerated swing, corresponding respectively to a desirably or insufficiently accelerated swing of a golf club, relative to a golf ball, the shaft having a longitudinal bore and an exterior surface,

(b) the shaft having, and confined near one end thereof, through holes intersecting said bore and said exterior surface, to produce a distinctive audible sound when said lightweight shaft is swung so as to define a desirably accelerated swing, the holes spaced about said axis,

(c) means for closing said one end of the tubular shaft,

(d) and a golf club shaft section extending into the opposite end of the tubular shaft, remotely from said holes and being bonded to said bore, and a golf club grip on said golf club shaft section, exteriorly of said tubular shaft.

2. The device of claim 1 wherein said holes extend through opposite sides of the tubular portion.

3. The device of claim 1 wherein said holes are spaced apart lengthwise of the shaft.

4. The combination of claim 1 wherein said lightweight shaft consists of synthetic resin.

5. The combination of claim 1 wherein the shaft is upright, and including a cap on and closing the lowermost end of said tubular portion.

6. The combination of claim 5 wherein said holes include groups of holes spaced about an axis defined by the shaft at about 90 degree intervals.

7. The combination of claim 6 wherein the holes of each group are spaced apart lengthwise of the shaft.

8. The combination of claim 7 wherein the holes of successive groups, about the shaft axis, are staggered, axially.

9. The combination of claim 1 including a tubular closure cap fitting over and bonded to the tubular shaft, at said one end thereof, proximate said holes.
