This invention relates to improvements in grips for golf club shafts and the like and particularly to an improved grip which can be readily applied to the shaft and which will permit the shaft to be firmly and easily held without turning or slipping. These, therefore, are the general objects of the present invention.
A more specific object of this invention is to provide a grip for a golf club shaft which may be readily manufactured and which may be readily applied to the shaft without the use of a cement between the club shaft and the grip, and which when applied will facilitate the holding of the shaft.
Another object of this invention is to provide a preformed strip of resilient material, such as rubber, which may be wrapped spirally about the shaft of a golf club or the like and which may be so wrapped as to eliminate or avoid the use of an adhesive material between the shaft and the strip and yet which will not slip relative to the shaft when in use.
Another object is to provide a grip for a golf club or the like having the advantages above mentioned, which may be readily used as a replacement for existing grips, and which will be attractive in appearance and provide a satisfactory feel.
Other objects and advantages of this invention will become more apparent from the following description reference being made to the accompanying drawings which illustrate preferred examples of the invention. The essential features of the invention will be summarized in the claims.
In the drawings, Fig. 1 is a fragmentary view of a golf club shaft having the improved grip of this invention; Fig. 2 is a plan view of the preformed strip of resilient material which forms the improved grip; Fig. 3 is a sectional view of the strip, the plane of the section being indicated by the lines 33 in Fig. 2; Figs. 4 and 5 1 are views, partially in section, illustrating different forms of caps or tip pieces which may be used in connection with the improved grip; Fig. 6 is a view of the club shaft and illustrates the manner in which the winding of the strip is started; Fig. 7 is a fragmentary view of a club shaft and illustrates the manner of winding of the strip as it nears completion; Fig. 8 is a view similar to Fig. 7, illustrating the strip completely wound and ready to be secured in place; Fig. 9 is a bottom view of the strip illustrated in Fig. 2; Fig. 10 is a fragmentary section through the wound shaft, the plane of the section being indicated by the lines Ill-l0 on Fig. 1; Figs. 11 and 12 are fragmentary sections, similar to Fig. 10 but illustrating the application of a decorative or reenforcing winding; Fig. 13 is a fragmentary perspective view of a modified form of grip wherein the cap or tip piece is formed integral with the grip itself; Fig. 14 is a sectional detail as indicated by the lines -44 on Fig. 13; Figs. 15 and 16 are sectional views of modified forms of strip; Fig. 17 is a fragmentary plan view of a modified form of strip; and Fig. 18 is a plan view of the strip shown in Fig. 17 tensioned for application to the club shaft.
The invention has been illustrated in the drawings as applied to a conventional steel golf club shaft 20. These shafts are tubular and are tapered, sometimes in graduated section, toward the lower end of the shaft to which a head, not shown, is affixed in the usual manner. Generally the upper end of the tubular shaft is closed by a cap or tip piece 2|.
A conventional cap, shown in Fig. 4, comprises a plug portion 22 which is driven into the open end of the shaft and a button-like tip portion 23 which overlies the top of the shaft and provides a flange 24 against which the grip material is seated.
An improved cap 25, especially adapted for use in the present invention, is shown in Fig. 5. The improved cap comprises a tubular or cup-like portion 26 into which the upper end of the club shaft is inserted, and a cap portion 21 having a downwardly facing flange 28 against which the upper end of the grip is abutted. This cap is made of a resilient material such as rubber or a rubber-like composition and snugly engages the shaft.
The improved grip comprises an elongated preformed strip 30 of rubber or resilient rubberlike material having a surface which, when stretched, provides sufficient friction to assist in retaining the strip on the shaft and provides an outer surface which may be readily gripped and which has a highly satisfactory feel". The strip 30 is preferably molded and is provided with a substantially longitudinal flange 3| which extends the entire length of the strip. The under surface of the flange is contiguous or flush with the under surface of the body portion 32 of the strip. The flange 3| is materially thinner than the body portion 32 of the strip and forms substantially a right angle with the body portion of the strip, as indicated at 33 in Fig. 3.
The bottom of the body portion 32 of the strip 30 is provided with a longitudinal undercut or groove along the longitudinal edge thereof opposite the flange 3|. The dimensions of this groove are identical with those of the flange 3| so that when wrapped about the shaft the groove will overlie the flange and be completely fllled thereby. The outer corners 36 of the flange and the inner corners 31 of the groove are both substantially ninety degrees. Thus when wrapped spirally about the shaft as shown in Figs. 1 and 10 the surfaces 40 and ll of the flange abut the surfaces 42 and 43 respectively of the groove and prevent relative movement of the strip aixally of the shaft 20. The outer corners 41 and 48 of the body portion 32 are rounded and coact to provide a spiral groove 49 when the strip is wound about the shank.
The ends of the body portion 32 of the strip are beveled as shown at 50 and lil. The angle of this bevel is such that when spirally wound about the shaft the beveled surface 5| lies in a plane normal to the axis of the shaft 20 thus enabling it to abut the shoulder 24 or 28 of the cap 20 or 25. The other beveled surface lies in a similar plane so as to facilitate fastening thereof to the shaft as indicated in Figs. '7 and 8.
The flange 3| extends some distance to either end of the body portion 32 as shown. at 6|! and BI. Th end of the flange 3| is comparatively thin, and is wrapped about the shaft as shown in Fig. 6 until the beveled portion 5| engages the flange of the cap whereupon the strip is spirally wound about the shaft atop the end of the flange. The strip is stretched as it is wound so that it tightly engages the shaft and i wound with the groove 35 at the top and the flange 3| toward the bottom of the shaft. Thus the portion of the strip overlaying the flange 3| will retain the strip in position on th shaft. This, together with the abutting edges heretofore mentioned, prevents any creeping or relative movement between the strip and the shaft and avoids the necessity of using cements or adhesives as has been the custom in the past.
When the strip is completely wound the extension 6| of the flange 3| i wound about the shaft and, as indicated in Fig. 8, thereafter wrapped with a band of adhesive tape 10 or bound with twine at its lower end in the usual manner to form a complete grip as shown in Fig.
When the cap or tip 25 of Fig. 5 is used the tensioned strip 3|], when wound about the tubu-= lar portion 26 of the cap, retain the latter in position on the shaft.
In Figs. 13 and is I have shown a modified form of grip. at the leading end of the flange 3| is omitted and a cap portion is moulded integrally with the strip at its leading end. This cap portion includes a cylindrical sleeve portion 56-, adapted to embrace the end of the shaft, and a closing cap portion 61.
In Figs. 15 and 16 I have illustrated embodtments which may be used when a decorated grip is desired. In these embodiments the body portion of the strip is provided with a series of openings or perforations H! which extend through the strip. These perforations are preferably substantially elliptical as shown in Fig. 17, so that when the strip is tensioned during winding, they will become substantially circular, as shown in Fig, 18.
In the form illustrated in Fig. 15 the openings 10 extend through that portion of the strip overlying the groove 35 and are covered by an elongated strip H of rubber or a rubber-like material In this form, the extension Gil Y 4 differing in color from that of the main portion of the strip. In this form the groove 88 is of such depth, that when the strip II is applied. it will be completely filled by the flange 0|. The strip may be secured to the strip 80 either by cement or by vulcanization.
In the form shown in Fig. 16 the strip comprises a body portion II of substantially the same thickness throughout substantially its entire length and provided with openings II which extend therethrough. A second strip of material H of the same width as that of the strip ll but somewhat thinner is secured to the bottom of the strip 13. The stri 14 is ofl'set transversely of the body portion 13, thus providing a tongue Ila and a mating groove Ila. The strip Il may be secured to the stri 18 by vulcanization or by cement, as desired, and is preferably of a contrasting color.
The grip may be decorated by winding 0. thin rubber ribbon II in the groove M as indicated in section in Fig. 11. This ribbon is oi a contrasting color or tone relative to that of the body portion of the strip, thus providing an attraotive grip.
A reenforcing winding 1! may be seated in the spiral groove 40. This winding may be nylon or stranded wire and is wound about the groove under considerable tension so as to reenforce the shaft and increase the adhesion between the shaft and grip.
While I have illustrated and described my improved grip as used in connection with a golf club, it is obvious that it may be used for hand grips for clubs, bats, and implements of various types when a wrapped grip is desirable.
