Description
Feb. 15, 1966 c. E. STROBURG HAND GUIDE FOR BOWLERS Filed Feb. 27, 1963 s r. m e w w w R E a w v R T N A W m 4 a United States Patent 3,235,258 HAND GUIDE FOR BOWLERS Clark E. Stroburg, Blockton, Iowa Filed Feb. 27, 1963, Ser. No. 261,321 9 Claims. (Cl. 273-54) This invention relates to an aid in the sport of bowiing and more particularly to a hand-worn accessory designed to maintain a correct relationship of the hand to the wrist when the ball is released.
Bowling balls are delivered either as a straight ball or with a curve of varying degree and according to the degree and type of curve imparted thereto, they are designated as a curve ball, a hook ball or a backup ball. The hook ball is most commonly used by those proficient in the sport and results in the ball veering sharply to the left (for a right-handed bowler) about twothirds of the way down the alley in order to strike the pins in what is known as the 1-3 pocket. To accomplish this result consistently, it is necessary to maintain the back of the hand on the same plane as the wrist with the thumb hole at the nine oclock position at the time of release" in order to impart the proper spin to the ball.
Many types of hand-worn accessories have been devised to aid in maintaining the desired hand position but it appears that most of them are quite cumbersome and are quite restrictive on hand movement both when being used for their intended purpose and when being worn intermediate periods of use,
Accordingly, one of the important objects contemplated by this invention is the provision of a new and improved hand guide for bowlers which incorporates a resilient strip or band overlying the back of the hand and secured at one end to a pair of spaced bracelets or straps which are attached to the wrist at respective opposite sides of the wrist joint.
Another object inhering herein is the provision of a hand guide as characterized in which the rearmost bracelet may be of the endless expansion type and the forwardmost bracelet, next to the hand, is preferably of a buckletype pliable strap which may be securely tightened about the wrist. By having a rear bracelet as described, this device is most conveniently mounted and avoids the difficulties that would be encountered in attaching the same to the wrist if all of the straps were of two-piece buckle types.
Still anotherimportant feature in this device resides in providing that the overlying strap is made in two sections longitudinally arranged in partial overlapping relationship and pivotally attached to each other whereby the hand engaging portion may be easily and quickly pivoted away from the hand and positioned to overlie its other part. This permits the guide to be worn without the restrictive contact of the strap on the hand when the user is not engaged in delivering the ball.
A further object in this invention includes a means to adjust the tension of the strap on the hand.
To attain these objects and such further objects as may appear herein, or be hereinafter pointed out, reference is made to the accompanying drawings forming a part hereof, in which:
FIG. 1 is a perspective view of this invention shown attached to a users hand and with the hand shown holding a bowling ball,
FIG. 2 is an enlarged perspective view showing a preferred embodiment of this invention in operable position,
FIG. 3 is a view similar to FIG. 2 but showing a modified form using two pliable buckle-type bracelets and also showing the hand engaging portion of the strap moved to an inoperable position,
FIG. 4 is a cross-sectional view taken on the line 4-4 of FIG, 2,
FIG. 5 is a cross-sectional view taken on the line 55 of FIG. 3, and
FIG. 6 is an enlarged exploded view of the tension adjusting nut to illustrate the novel construction thereof.
Referring to the drawing, a pair of wrist bracelets or straps are designated by the numerals 10 and 12 with strap 10 being referred to as the rear strap or bracelet and strap 12 and the forward strap or bracelet in relation to their position on the hand 14 when in use. Strap 16 is preferably shown in the form of an endless expansion bracelet (FIG. 2) although it may be a buckle-type pliable strap of leather or the like as shown at 16 in FIG. '5 which is the type employed for strap 12. By using an expansion bracelet for the rear strap, one can easily slip it over the wrist whereby the entire device 18 is supported while the forward strap 12 is being tightly secured. With both bracelets of the open buckle-type, one can experience considerable fumbling and awkwardness at times before the straps are secured.
The bracelets are provided with rigid plate members 20 in a well-known manner to which attachments can be affixed and connected to plates 20 on both bracelets as shown in a relatively rigid but resilient band or hand guide assembly 22 which includes the fiat connecting strip or link 24' pivotally attached at one end 26 to the rear bracelet 10 as by a rivet 28 and pivotally attached at point 30 to the forward bracelet 12, point 30 being near but spaced inwardly from the opposite end 32 of link 24. At point 39 the fastening member is in the form of an upstanding threaded pin 34 which carries a small coil spring 36 intermediate plate 26 and link 24 as shown in FIG. 4, it being noted that point 30 defines a hole through which pin 34 projects. Link 24 is also provided with the longitudinally spaced holes 38 and 40 on respective opposite sides of hole 30 and equally spaced therefrom, With hole 40 being at link end 32.
The hand engaging portion of assembly 22 includes an elongated flat relatively firm but resilient band 42 curved slightly upwardly at its forward end 44 and having the underside of portion 40 provided with a padding 46. The rear end portion 48 of band 42 is pivotally mounted on pin 34 through a hole 50, and spaced longitudinally from hole 50 toward band end 44 is a depending lug or boss 52 so spaced as to seat in either hole 38 or 40 of link 24 as follows:
In the operable position of assembly 22 (FIGS. 2 and 4), the rear portion 43 of band 42 overlies the forward portion of link 24 and lug 52 is snapped into and through hole 40 to effectively lock band 42 against any movement away from longitudinal alignment with link 24. A nut 54 is threaded to pin 34 to hold band 42 in place whereby assembly 22 may be susceptible of yieldable movement toward and away from bracelet 12 due to spring 36. Such yieldability may be adjusted by tightening or loosening nut 54. In this respect it is pointed out that the underside of nut 54 (FIG. 6) has oppositely disposed depending keys 56 relative to the bore 58 which will seat in the recesses 60 extending radially from the upper surface of band 42 relative to hole 50. This arrangement perm-its quarter turn adjustments of nut 54 and serves to lock the nut from accidentally becoming loosened.
To place band 42 in its inoperable position (FIGS. 3 and 5), the forward end 44 is elevated sufliciently for lug 52 to be withdrawn from hole 40 and the band is then pivoted on pin 34 until lug 52 snaps into hole 33 and the position of band 42 is changed from overlying the back of hand 14 to overlying the wrist of the user. It will be appreciated that this feature affords a most convenient and simple means to render this device inoperable without having to remove it from the hand. Thus if a user wishes to bowl without the guide during a part of any game, or to stop for an intermission break, a simple reversal of band 42 permits normal unrestricted use of the hand without disturbing the wrist straps or bracelets. Band 42 is returned to operable position by the same movement described above. Thus the end 44 of band 42 is elevated and turned to move it from or to either position.
From the above description and as seen in FIG. 1, band 42 will overlie the back of the hand 14 with pad 46 actually in contact therewith for obvious reasons. Band 42 is stiff enough, being preferably made of a light gauge spring metal, to act as a splint-like stop against bending of the hand and to thus maintain the back of the hand coplanar with the wrist. Thus if the ball is released with the thumb at the nine oclock position, the hand is in proper position for imparting the proper spin to the ball 62 and the tendency to bend the hand outwardly will be prevented by assembly 22.
It is submitted that the invention shown and described is aptly suited to achieve the purposes intended and is characterized by a combination of highly useful and mutually cooperating elements that combine their respective and proportionate functions in accomplishing the objects sought to be obtained. A
It will be understood that the phraseology employed herein is for the purpose of description and not for limitation and that modifications and changes in the construction and arrangement of this invention can be made within the scope of What is claimed, without departing from the spirit and purpose thereof. It is thus intended to cover by the claims, any modified forms of structure or mechanical equivalents which may be reasonably included within their scope.
