DESCRIPTION:
BRIEF SUMMARY
This invention relates to a device which aids a golf player in obtaining and maintaining a correct, or at least near correct, golf swing.
BACKGROUND ART
A number of devices have been known in the art which allow a golfer to practice his swing. Such devices have basically fallen into two categories: those which constrain the golf club in some manner; and those which do not constrain the golf club. Swing aids of the former type have generally been fairly large devices which take up considerable space and are relatively expensive to produce. Devices of the latter type, generally enjoy a much lower cost of production and smaller volume however they do not really serve the object of the present invention in that the club may still be swung through any trajectory.
DISCLOSURE OF INVENTION
It is therefore an object of the present invention to provide a golf swing aid which will overcome, or at least substantially ameliorate, the disadvantages of the foregoing prior art.
Accordingly, in one broad form, the present invention may be said to consist in a golf swing aid comprising: a substantially rigid member including first and second end extremities; a first joint, including attachment means, at said first end and providing relative pivotal movement between said attachment means and said member; a second joint, adapted to be attached to a golf club, at said second end and providing relative pivotal movement between said golf club and said member.
Preferably, the golf swing aid before described is used with said attachment means attached to a rigid vertical surface at a location substantially raised above ground level so that a golf club attached to said second joint may be swung in a normal manner while the lower portion of the shaft is constrained by said golf swing aid to follow a substantially planar trajectory.
BRIEF DESCRIPTION OF DRAWINGS
By way of example only, one embodiment of the present invention will now be described with reference to the drawings in which:
FIG. 1 is an perspective view of the apparatus while in use;
FIG. 2 shows one portion of the apparatus of FIG. 1;
FIG. 3 shows the portion of FIG. 2 from an alternative angle;
FIG. 4 shows an alternative embodiment of the portion shown in FIGS. 2 and 3; and
FIG. 5 shows a further portion of the apparatus of FIG. 1.
BEST MODE OF CARRYING OUT THE INVENTION
Elongate member 10 includes pivotal joints 11 and 12 at its opposite extremities. Member 10 is produced in glass or carbon fibre reinforced plastics, aluminium extrusion or other suitably strong, preferably lightweight material. Pivotal joint 11 (FIG. 2) includes anchor plate 13 adapted to be slidingly engaged with a wall bracket 14. In use wall bracket 14 is attached to a vertical surface so that it extends substantially vertically and is some distance above the general ground level. Anchor plate 13 is adjustably fixed to wall bracket 14 by a suitable screw in threaded hole 18 co-operating with a suitable hole 19 so as to provide a vertical adjustment of the pivot 11.
Attached directly to rigid member 10 is an angle setting member 15 which is pivotally attached via bush 23 to an anchor pivot member 16. Anchor pivot member 16 is further attached to anchor plate 13 described above. Angle setting member 15 includes two disk portions superposed and relatively pivoted about a central axis. The co-operative faces of the two halves of angle setting member 15 are mutually fixed during use of the apparatus by radial serrations as clearly seen in FIG. 3, in an alternative form, or by inserting a screw into a hole 22 as shown in FIG. 4. As will further be described herein below angle setting member 15 provides a means for adjusting the important cone angle between the rigid member 10 and the pivot within bushing 23.
A second important angle which is adjustable, but fixed during operation of the apparatus, is between the anchor pivot member 16 and the anchor plate 13. By altering this angle the axis about which the whole apparatus rotates during use, that is the pivot axis in bushing 23, is set. Thus
