, l BOWLER'S WRIST SUPPORT FIELD OF INVENTION The present invention relates to a wrist support and more particularly to a bowlers wrist support designed to hold the bowlers wrist and the back of his hand fixed so that the hand and forearm will move in union with the wrist slightly bent inwardly.
BACKGROUND OF THE INVENTION In order to better the score in bowling matches it is important to throw the ball in such a way as to produce heavy pin action. Various ways of throwing the ball have been studied, and ithas been found that it is important to impart strong spinning to the ball at the instant when the ball-leaves the fingers. In orderto produce such strong spinning action, it is necessary to remove the thumb from the ball hole earlier than the other two fingers so that the remaining fingers may tend to pull up and turn the ball. At this time, if the bowlers wrist is upwardly or outwardly bent, the thumb and the other fingers would be withdrawn from the respective holes at the same time, so that the spinning can no longer be given to the ball. The thumb can be withdrawn from the hole sooner if it is positioned more rearwardly of the ball as it is swung down forwardly from the backward upper position. Also, if the remaining fingers are positioned in the lowerpart of the ball, the ball can be pulled up and turned more strongly and for a longer time. In order to meet this condition, it is desirable that the bowler slightly bend his wrist inwardly. To this end, a wrist support means, which permits the thumb to be withdrawn from the ball hole earlier than the other fingers, has heretofore been desired. A prior-art wrist support means that has been provided to meet this requirement has a wrist support pad reinforced with a flat rigid core, which is applied over the outer side of the wrist or applied to cover the wrist and the back of the hand and fastened thereto by means of leather strings. This prior-art wrist support means if fairly effective in preventing the wrist from bending outwardly since the rigid pad is fastened and fixed to the outer side of the wrist. However, it has some shortcomings. Firstly, the wrist cannot be bent inwardly due to the rigid pad. Secondly, compatability with various sizes and forms of the wrist and the back of the hand is not obtained. Thirdly, it is very inconvenient to fit the wrist support means to the bowling hand by the other hand since it is intended to be fitted to the bowling hand by fastening a buckle provided on a fastener band. It has been strongly desired, accordingly, that the above shortcomings inherent in the prior-art wrist support means be overcome and a novel wrist support means free from these shortcomings be devised.
SUMMARY OF THE INVENTION A further object of the invention is to. provide a wrist support means, which can bereadily fitted to and removed from the bowling hand by the other hand of the bowler.
The above and other objects of the invention will become apparent from the following; description.
The above objects of the invention are achieved by the provision of a rigid core member having a particular configuration, being curved longitudinally to cover both wrist and the back of the hand and being curved laterally to be closely fitted thereto, and also by the provision of fastening members permitting fastener bands to be fastened in positions over the upper and lower portions of the back of the hand and over the wrist portion.

DESCRIPTION OF PREFERRED EMBODIMENTS FIGS. 1 to 7 show one embodiment of the invention. It consists of a rigid section A, whose left hand edgeis joined to a substantially L-shaped wrist fasteningisection B, whose upper right portion is in turn joined toa palm cover section C. As an alternative, the palm cover section C may be directly connected to an upper portion of the right hand edge of the rigid section A.
A leftwardly extending fastener band 1 is provided at the upper end portion of the rigid section A, and to the hand end of the fastenerband l a pile fastening member 5 is provided. Also, hook fastening members 6, 8 and 9 are respectively provided at the upper right hand portion, intermediate portion and lower portion of the rigid section A. Two fastening bands 3 and 4 are connected to the right hand edge of the wrist fasteningsection B, and pile fastening members 10 and 11 areprovided over the back of right hand end portions of the fastening bands 3 and 4. These fastening members may, for instance, be Velcro." Although only a single fastening band may be attached to the wrist fastening section B, in order to closely fix the rigid section A to a wrist of whatever shape it is desirable to provide two fastening bands. A further fastening'band 2 is attached to the right hand edge of the palm cover section C, and a buckle 7 is provided at the right hand edge of the fastening band 2. Suitable sheet-like material such as cloth, synthetic resin sheets, leather and artificial leather may be employed to form the front and back of the rigid section A, wrist fastening section B, palm cover section C and fastening bands I, 2, 3 and 4. The rigid member A has an inner core consisting of a front side rigid member 12 and a back side resilient member 13.
Although the rigid member 12 may have a length such that it extends up to the fore end of the back of the hand as shown in FIGS. 1 to 7, it may desirably extend up to the first joint of the fingers, as shown in FIGS. 8 to 14, in order to prevent outward bending of the fingers. This is because if the fingers are bent outwardly, the afore-mentioned effect obtained by slightly bending the wrist inwardly is partly offset. Thus, the rigid member 12 may have a length of l l to 22 cm, desirably 14 to l 9 cm, and a width of 5 to 9 cm, desirably 6 to 8 cm. The radius of curvature of its longitudinal section as shown in FIGS. 6 and 13 is about 250 to 3,000mm, desirably about 500 to 1,500 mm, while the radius of curvature of its lateral section as shown in FIGS. 7 and 14 is about 30 to 1,000 mm, desirably about 50 to 500 mm. The core of this curved configuration permits the rigid section to be closely fitted on the back of the hand and the wrist, so that it has a pronounced effect of preventing the outward bending of the wrist. Such a core has never been known heretofore. The material of the rigid member 12 is subject to no restrictions, and well-known materials such as iron, steel and like metals and also various plastic materials may be effectively used. The wrist fastening section B joined to the rigid section A has an enclosed resilient member 16 as shown in FIGS. 4 and 11, so that the wrist can be fixed more effectively. The palm cover section C is provided with a number of openings or air holes penetrating from its back to its front as shown in FIGS. 1 and 3 and in FIGS. 8 and 10, so that the inner side of the wrist and the palm will not be stuffy with sweat. The size of the opening is about I to 4 mm in diameter and desirably about 2 to 3 mm in diameter. Numeral 14 designates a palm pad of a resilient material, which is applied over the front side of the palm cover section C and covered with leather or like material. It serves to fill the gap formed between the surface of the ball and the palm when the ball is gripped, whereby the ball can be gripped stably.
To fit the wrist support means according to the invention, the rigid section A is closely placed over the back of the hand and the wrist. Then, the wrist fastening section B and palm cover section C are folded back to be applied over the inner side of the wrist and the palm respectively. Then, the hook fastening members 8 and 9 provided on the rigid section A are fastened to the respective pile fastening members 10 and 11 on the fastener bands 3 and 4 connected to the wrist fastening section B. Also, the fastener band I provided on the upper end portion of the rigid section A is passed through the buckle 7 provided on the fastener band 2 connected to the palm cover section C, and the pile fastening member 5 and hook fastening member 6 provided at the opposite ends of the fastener band 1 are fastened to each other. In the above way, the bowlers wrist support means can be fastened to the wrist and hand of the bowler.
With the bowlers wrist support means described above according to the invention fitted to the ball since, the wrist is held in a slightly inwardly bent state, it is possible to ensure that the thumb is located rearwardly of the ball and the otherfingers at the bottom of the ball when the ball is swung down forwardly from a backward upper position thereof so that the thumb can be withdrawn from the ball hole earlier than the other fingers and that the ball can be pulled up and turned strongly for an extended time by the remaining fingers. Thus, strong spinning action will be imparted to the ball, and the released ball will produce pin action of high strike efficiency.
Also, the bowlers wrist support means can be fitted and removed very simply since this can be done by merely fastening or unfastening the fastener bands by means of the fastening members.
Further, even if the bowlers wrist support means is fitted for a long time, the palm will not get stuffy with sweat so much by virture of the air holes.
It is to be understood that the invention is not limited to the embodiments disclosed which are illustratively offered and that modifications may be made without departing from the invention.
