ABSTRACT:
This invention relates generally to a golf swing practice device for warm-up and muscle memory prior to playing a game of golf, and is useful also for training one's self to develop a grooved swing pattern and to build up golf swing related muscles. It further relates to a novel and simple method of attaching the swing baffle to the shaft of a golf club.
BACKGROUND OF THE INVENTION
Numerous types of golf club swing baffles are disclosed in the prior art for the purposes noted above. Several require fasteners to attach and detach the baffle, some are snap-on types of units, while some others fail to disclose how they are connected and disconnected, leaving one to assume the latter may be permanently installed on a club and are dedicated to only the practice mode of use. Some units are intended to be loosely connected to the shaft, some tightly held thereonto and at least one is said to be frictionally held on the shaft but is capable of rotation if an improper swing is made. Obviously, the baffle of the last-mentioned arrangement can only fit one manufacturer's shaft diameter and taper or others that are identical in diameter and taper. The large differences in shaft diameters and taper from one manufacturer to the next make the arrangement appear of questionable value, particularly since its inventor fails to indicate how one can distinguish a bad swing from a good swing.
SUMMARY OF THE INVENTION
A one-piece plastic molded baffle has a plurality of vanes extending lengthwise of a shaft to which it is to be attached. A central hub has a lengthwise opening therethrough and a slot communicating the opening to the exterior of the hub between two adjacent vanes. A pair of baffles diametrically opposite the slot are squeezed together with one hand to expand the slot and thereby enable the baffle to be easily placed onto or removed from the shaft of a golf club. The material of which the baffle is made has high memory retention, allowing the opening to be sized to firmly grip all standard shaft diameters.
A principal object of the invention is to provide a one-piece golf club swing baffle capable of being easily installed and removed relative to a golf club shaft, without the use of tools or independent attaching elements.
Another object is to provide a novel method of applying the foregoing baffle to a golf club shaft, utilizing only the fingers and heel of one hand to manipulate the baffle.
Still another object is to provide a baffle of a size and shape readily carried in a conventional golf club bag during play of the game of golf.
Another object is to provide a baffle that is symmetrical from one end to the other and therefore make it easily injection-moldable and universally usable by either a right or left-handed golfer.
Other objects and advantages will become apparent from the following description, in which reference is made to the accompanying drawings.
