This application takes priority from and claims the benefit of U.S. Provisional Patent application Ser. No. 61/663,328 filed on Jun. 22, 2012, the contents of which are herein incorporated by reference.
FIELD OF THE INVENTIONThis invention relates generally to sporting good apparatuses and more particularly to sports shaft and golf shaft grip and head systems possessing interchangeable characteristics in order to allot the user various strategic choices during purchase, practice and game play.
BACKGROUND OF THE INVENTIONOn present day golf clubs, the grip of the club is attached to the opposite end of the shaft from the club manufacturers, and is the part of the club the player holds on to while swinging. Originally, grips were composed of one or more leather strips wrapped around the shaft. The leather outer wrap on a grip is still seen on some clubs, most commonly putters, but most modern grips are a one-piece “sleeve” made of rubber, synthetic or composite material that is slid over the shaft and secured with an adhesive. These sleeve grips allow clubmakers and golfers to customize the grip's diameter, consistency (softness/firmness) and texturing pattern to best fit the player. Clubs with an outer “wrap” of leather or leather-like synthetic still typically have a “sleeve” form underneath to add diameter to the grip and give it its basic profile.
Advances in materials have resulted in more durable, longer-lasting soft grips, but nevertheless grips do eventually dry out, harden, get worn or are otherwise damaged and must be replaced. Replacement grips sold as do-it-yourself kits are generally inexpensive and of high quality, although custom grips that are larger, softer, or textured differently from the everyday “wrap”-style grip are generally bought and installed by a clubsmith.
Regripping often requires toxic, flammable solvents to soften and activate the adhesive, and a vise to hold the club steady while the grip is forced on. The newest replacement kits, however, use double-sided tape with a water-activated adhesive that is slippery when first activated, allowing easier installation. Once the adhesive cures, it creates a very strong bond between grip and shaft and the grip is usually impossible to remove without cutting it off.
Presently, many golf grips are secured to a golf club shaft by use of double sided adhesive tape. Tape is applied to a golf club shaft. Acetone is poured over the adhesive tape to eliminate the adhesive nature on a short term basis. The grip is pressed over the end of a shaft with the adhesive tape and slid into position. The adhesive tape becomes adhesive very quickly making grip placement difficult. Movement of the grip is difficult as the adhesive tape grabs the grip making proper alignment difficult. The end of a shaft is reverse tapered so the shaft end is much larger than a grip opening making placement difficult.
Additionally, as mentioned above, in concurrent systems, removal and replacement of a grip normally takes a great amount of time and labor as the grip must be cut off and the adhesive must also be removed. Therefore, as this involves a tedious, labor intensive and time consuming process, it is virtually impossible for users to test different grips on clubs to ascertain which feel suits the user. It would be advantageous to be able to try on and off grips to determine which is preferable to a golfer.
Presently, golf clubs including putters, irons, metals, woods and drivers are sold with a grip, shaft and club head predetermined by golf club manufacturers. If a golfer prefers a different type of grip, shaft or club head, either based on material, size, shape, color or other characteristic, be it structural or aesthetic, the golfer must have the component changed after purchase is completed. Concurrently, placement and replacement of golf grips on golf club shafts with is extremely tedious as there is difficulty in both removing and installing the grips. Golf club heads are predetermined and never changed. When clubs wear with use over a period of time, a golfer is more likely to buy new clubs than place new shafts. The present time consuming process does not allow for changing a grip or club head at the time of purchase.
Presently, golf grips are placed on a shaft by placing double adhesive tape onto the shaft covering the length of the grip. The inner layer of the adhesive tape provides a secure interface tape to a shaft while the outer layer of adhesive tape provides a secure interface to the inside of a grip. Unfortunately, it is difficult to slide the grip over the adhesive surface of the tape and solutions such as acetone are poured over the adhesive tape and into the grip to produce a slippery surface, which allows the grip to slide down the shaft. However if the solvent evaporates too quickly, which happens often, the grip gets stuck half way.
Golf club heads are normally screwed onto shafts in such a manner as to change their position by creating a different loft, opening or closing the face angle. Normally, club heads are tried on for fitting to fit a person's height and swing such that the sole of a head is striking the ground in the middle. When it is determined which club head is appropriate, the information is sent to a manufacturer to have the clubs custom manufactured.
The club heads are almost always the same size, shape and aesthetic appearance, the only difference to be determined is the lie angle. It would be desirable to test different club heads in a store and with such a method, a golfer could theoretically leave with the clubs at the time of purchase. Additionally, club shafts are made of different materials, lengths and various aesthetic designs. It is a major project to change shafts as the head and grips which are glued to a shaft must be removed. New ones are then glued back on. It would be desirable to have shafts of different materials, shapes, colors, length and the like to test at the time of purchase.
SUMMARY OF THE INVENTIONThe instant apparatus and system, as illustrated herein, is clearly not anticipated, rendered obvious, or even present in any of the prior art mechanisms, either alone or in any combination thereof. A versatile system, method and series of apparatuses for creating and utilizing a golf grip for a golf club. Thus the several embodiments of the instant apparatus are illustrated herein.
The present invention provides a method to secure a golf club grip to a golf club shaft without the use of adhesive tape. A grip is constructed with internal structures that snap or lock into structures on a shaft or components attached to a shaft. The grip is solid elastic material or is adhered to a plastic, metal or other material internal component. The internal components may be one piece or constructed of several components. The shaft is tapered, parallel or reverse tapered at the grip end. A parallel is the preferred shape. The shaft has areas shaped to accept components on the grip that create resistance to grip removal.
A set of forces acting onto a golf club are generated while striking a golf ball. The swinging motion generated around a person's body creates centripetal forces, which could cause dislodgement of a shaft from a grip if proper resistance is not provided. Striking a ball with the club head creates rotational forces in one direction. Components to the new invention in several versions utilize the fact that little to no force is applied in the opposite rotation created by ball striking.
Twisting of a shaft in a grip while striking a ball is resisted by components constructed on a shaft and within a grip. Twisting in the opposite direction is resisted by snap components which compress or bend and release into or passed indentations or other components. Enough force is easily generated by hand twisting to disengage snap locks, however, the force is more that can be generated by using a club during a round of golf. In addition, forces of hands on to a grip secure it further to a shaft as components that need to expand for release are compressed. For the snap adaptation, there exist at least are three known main types of snap fits: annular, cantilever, and torsional.
In an exemplary embodiment, components in a golf club grip will compress, and thus the diameter of the grip will expand as the downward force of the grip placement occurs. Compression of components or grip diameter expansion is released and engagement of shaft components is engaged. A grip is held in position by these components. As illustrated herein, there may be as few as one component and as many as thousands depending on their size.
Depending upon the amount of usage, golf club grips regularly require removal and replacement. It is nice if grips are interchangeable to be able to try different grips on golf clubs to see which grip is most effective for a particular golfer. In one embodiment of the instant apparatus, grip removal can be predetermined to be difficult to avoid accidental separation during use. In yet another embodiment, removal and replacement may be render effortless in order to allow a golfer to test different grips and see which grip feels best.
Moreover, the ability to readily change grips may be especially high import for putter use as this feature would lend golfers the ability to test a thicker or thinner grip. Additionally, although herein embodiments of gripping mechanisms have been highlighted, the instant system and all embodiment thereof may be readily adapted for attachment of a club head to a shaft in an identical And, this qualifies as extremely important when golfers would like to try different combinations grips, shafts, clubheads.
It is an object of the present system to additionally introduce and employs several techniques for quick exchange of grips and club heads in order that a customer in a store may assess different grips, shafts, and club heads to determine which combination best suits the customer at the time of purchase. The customer will more likely buy a club if the feel is better based on the grip, shaft control and head performance. Determining which combination is better achieved by trying different components. In addition, a customer may determine that they do not like the grip, shaft or club head after purchase of golf clubs and have the opportunity to easily return and exchange it with another interchangeable grip.
It is also an object of the present system to reveal a series of easy exchange techniques to be utilized as grips, shafts or club heads wear, allowing for easy replacement of old worn grips with new ones, particularly as grips wear out several times a year for many golfers. Presently, the replacement of old worn grips is accomplished by a professional club builder or by a golfer themselves. If a golfer attempts to perform the replacement, the cost is reduced as the cost of profession labor is thus eliminated.
It is a primary object of the present system to introduce the concept of interchangeable components, especially grips, results in ease of placement and potential cost savings, which will inherently result in greater profits for golf companies and courses, as well as providing a better brand of golf for the user as the ability to have fresh grips and heads, without having to wait for a professional to perform replacement, will enable players to always possess their “A-game”.
It is an object of the present system to reveal techniques which allow exchangeable and interchangeable grips, shafts and club heads can include snap, screw, Velcro, interlocking, channels, Morses taper, friction or like methods of joining and disconnection parts quickly. It is a further object of the instant system to introduce at least three manners or methods in which components may be constructed to facilitate quick exchange.
It is a further object of the instant system to introduce a first manner or method in which components may be constructed to facilitate quick exchange wherein a shaft may be composed of uniform construction such that each end facilitates the technique of removal. It is a further object of the instant system to introduce a second manner or method in which components may be constructed to facilitate quick exchange wherein a shaft is constructed and altered after construction such as placing holes, grooves, threads, taper, slots, projections or the like.
It is a further object of the instant system to introduce a third manner or method in which components may be constructed to facilitate quick exchange wherein an existing shaft is cut and inserts into the shaft placed or inserts placed into or onto a shaft without cutting. In one embodiment, a shaft may have a groove, slot, dimple or like placed into a shaft during manufactured or altered after manufacture for provide the desired result. In an additional embodiment, a shaft may be cut and an insert fitted and glued with materials such as epoxy, which are used to hold club heads to shafts.
It is an additional object of the instant system to introduce a method for providing the consumer with a point of purchase system wherein the consumer can purchase the comprising the capability wherein purchasing a sports equipment gripping mechanism, and particularly a golf club grip, may be chosen to fit the consumer's requirements via the ability to interchange/exchange numerous grip types and sizes. Thus, the consumer can get in and complete the purchase of the grip of choice and the club of choice within a matter of minutes, even as few as ten minutes.
There has thus been outlined, rather broadly, the more important features of the versatile golf club embodiments in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto.
In this respect, before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and to the arrangements of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of description and should not be regarded as limiting.
These together with other objects of the invention, along with the various features of novelty, which characterize the invention, are pointed out with particularity in the claims annexed to and forming a part of this disclosure. For a better understanding of the invention, its operating advantages and the specific objects attained by its uses, reference should be made to the accompanying drawings and descriptive matter in which there are illustrated preferred embodiments of the invention.

The profit loss of others providing replacements is eliminated. There is more profit for the manufacturer of the club. For example, if different companies market and sell putters and one company offers a putter, than the interchangeable grips, shafts and club heads could be manufactured to possess different configurations such that grips, shafts and club heads of one company wouldn't fit the grips, shafts and club heads of another company. This would eliminate companies which make grips from supplying replacements.
The greatest opportunity for implementation of this concept may well be with putters. The ability to have different grips and different club heads connect with different length shafts creates an exponential number of choices for the user. Just as different golfers require different putter lengths, many different golfers desire different grip sizes, shapes, appearances, as well different putter heads. Therefore, retail stores and pro shops would be required to stock different grips, shafts and club heads, which would require minimal space when compared to the same number of putters, to achieve similar results.
Therefore, illustrated in one embodiment is a method for providing the consumer a point of purchase system comprising the capability wherein purchasing a sports equipment gripping mechanism, and particularly a golf club grip, may be chosen to fit the consumer's requirements via the ability to interchange/exchange numerous grip types and sizes. Thus, the consumer can get in and complete the purchase of the grip of choice and the club of choice within a matter of minutes, which could range from ten minutes to 30 minutes.
