DESCRIPTION:
BRIEF SUMMARY
The present invention relates to golf and in particular to a golf swing trainer.
The invention has been developed primarily for use with golf clubs and will be described hereinafter with reference to that application. However, it will be appreciated that the invention is not limited to this particular field of use and is also suitable for tennis rackets, cricket bats and other sporting implements.
It has long been a goal for golfers to reproduce either a text book or preferred swinging action when striking the ball. Hitherto, this has involved not only extensive practice, but the use of expensive video equipment and/or a coach to view the swinging action. Accordingly, much time and expense is involved.
The above problem is exacerbated because a slightly different swinging action is required for each of the different clubs used.
It is an object of the present invention, at least in the preferred embodiment, to overcome or substantially ameliorate this disadvantage of the prior art.
According to a first aspect of the invention there is provided a golf swing trainer including an axially extending tubular body for mounting to the handle of a golf club, two chambers disposed within and/or adjacent to the body, and a circumferentially extending guide track disposed within the body and between the chambers tracking means selectively supported by the guide track, wherein, during a predetermined swinging of the club the tracking means moves between the chambers and the guide track and provides an indication of the movement.
Preferably, the guide track extends around the interior of the body to define a circular path for the tracking means and the indication provided by the tracking means is audible.
Preferably, the body includes a centrally disposed radially extending mount for selectively engaging in an interference fit the free end of the handle.
Preferably also, the body is cylindrical and includes a first and a second tubular insert for defining the first and second chambers which extend coaxially from respective ends of the body and terminate adjacent to the centre of the body to define the guide track. More preferably, at least one of the tubular inserts is movable with respect to the body for selectively adjusting the axial extent of the track. Even more preferably, at least one of the inserts is threadedly engaged with the body and includes a locking collar for selectively securing the insert at a predetermined position with respect to the body.
Preferably, the body and inserts are produced from a transparent plastics and the tracking means is a spherical metal body. In alternative embodiments the body is aluminium.
According to a second aspect of the invention there is provided a swing trainer including an axially extending tubular body for mounting to the handle of a sporting implement, two chambers disposed within and/or adjacent to the body, and a circumferentially extending guide track disposed within the body and between the chambers for selectively supporting tracking means, wherein during a predetermined swinging of the implement the tracking means moves between the chambers and the guide track and provides an indication of the movement.
According to a third aspect of the invention there is provided a golf swing trainer including an axially extending tubular body for mounting to the handle of a golf club, said body including closed ends and housing tracking means for selectively striking the ends and providing an audible indication thereof during a predetermined swinging of the club.
According to another aspect of the invention there is provided a method of practicing a golf swing including the steps of: the indications.
A preferred embodiment of the invention will now be described, by way of example only, with reference to the accompanying drawing in which:
FIG. 1 is a schematic front elevation of a first embodiment of golf swing trainer according to the invention, mounted on a golf club;
FIG. 2 is a diagrammatical representation of the club positions during different stages of a golf swing;
