BOWLERS WRIST SUPPORT BACKGROUND OF THE INVENTION This invention relates to bowlers wrist supports and, more particularly, to a bowlers wrist support to be fitted on the bowlers wrist in order to prevent the wrist from bending outwardly when the bowler releases his ball.
Balls employed in bowling matches are quite heavy, so that the wrist of the hand holding a ball is often bent outwardly when releasing the ball. If the ball is thrown with the wrist bent outwardly, it is impossible to impart a spinning action to the ball and the resultant throw is nothing other than a so-called haul, which is not effective in creating pin action. Accordingly, a wrist support which permits the bowler to hold and release a ball properly, without the possibility of causing the wrist to be bent outward, has heretofore been desired.
DESCRIPTION OF THE PRIOR ART There are wrist support bands that have been proposed to meet this need. FIG. 1 shows a typical structure of the prior art wrist support band. It consists of a rigid portion A reinforced with a rigid plate, flexible portions B, and a thumb insertion hole 1. In use, it is fitted on the wrist by inserting the thumb through the thumb insertion hole 1 and winding the band portions B around the wrist with the rigid portion A placed on the outer side of the wrist. This wrist support band extant in the prior art is fairly effective in preventing the wrist from bending outward since a rigid plate is contained as a core member within the rigid portion A. However, it has some shortcomings. First, since the thumb insertion hole is pre-formed, this is often incompatible with the various sizes of bowlers hands and the various thicknesses and lengths of bowlers thumbs. Since bowling is played by all ages from children to adults, male or female, and the size of the hand varies with individual bowlers, in many cases the rigid portion A cannot be placed well on the outer side of the wrist. In such cases, the intended use cannot be fully achieved. Second, while holding the ball it is not desir able for the palm to be covered with bands or the like, yet it is desirable to wind the band around the wrist as many turns as possible in order to secure the wrist support band. But if the wrist is wound with the band portion of the prior art wrist support band, two or three turns, a majority of the palm is covered, so that handling the ball becomes very difficult. On the other hand, winding the band only one turn is insufficient to secure the wrist support band. Third, as the band is wound, after the insertion of the thumb into the thumb insertion, it does not closely fit the hand but becomes loose at the stem of the thumb (indicated at 2 in FIG. 1). This is very inconvenient for holding and throwing the ball. Fourth, it is desirable for the rigid portion A to extend not only over the wrist but also over the back of the hand to promote the effect of preventing the bending of the wrist, this cannot be achieved with the prior art wrist support band. If the rigid portion A is increased such that it extends over the back hand, the palm is wholly covered by the band portion B. In such a case, the ball cannot be smoothly held and thrown.
SUMMARY OF THE INVENTION A further object of the invention is to provide a bowlers wrist support, which can be closely fitted on the wrist without any loosening at the stem of the thumb.
A still further object of the invention is to provide a bowlers wrist support, whose rigid portion can extend not only over the wrist but also over the back of the hand, and nevertheless whose band portion will not cover the palm.
The above and other objects of the invention will become more apparent fromthe following description.
DESCRIPTION OF THE PREFERRED EMBODIMENTS The unique features of the invention, to achieve the above objects, reside in that the band portion has a particular shape and that a thumb band is provided instead of forming a thumb insertion hole. These and other features of the invention will be more fully understood from the following description with reference to the accompanying drawing, in which:
FIG. 2 is a plan view of an embodiment of the bowlers wrist support according to the invention;
FIG. 3 is a view showing the embodiment of FIG. 2 actually fitted on the wrist viewed from the outer side thereof;
FIG. 4 is a view of the same viewed from the inner side of the wrist;
FIG. 5 is a sectional view taken along line 5--5 in FIG. 2;
FIG. 6 is a plan view showing another example of the bowlers wrist support according to the invention;
FIG. 7 is a view showing the embodiment of FIG. 6 actually fitted on the wrist viewed from the outer side thereof;
FIG. 8 is a view of the same viewed from the palm side.
FIG. 9 is a sectional view taken along line 9-9 in FIG. 6;
FIG. 10 is a plan view of a rigid member 9 enclosed within the rigid portion C;
FIG. 11 is a sectional view taken along line l1ll in FIG. 10; and
FIG. 12 is a sectional view taken along line 12-12 in FIG. 10.
FIGS. 2 to 5 show one embodiment of the wrist support according to the invention. It consists of a rigid portion C, a wrist band portion D joined to the right hand edge of the portion C and a thumb band portion E joined to the left hand edge of the portion C. The rigid portion C is provided on its upper portion with a hook fastening member 3. The rigid portion C consists of a front surface and a back surface of cloth, leather or a suitable packing material enclosing a core consisting of an outer rigid member 9 and an inner resilient member 10. While the rigid member 9 may be a flat plate as shown in FIG. 5, it desirably has a curved configuration curved both longitudinally and laterally .as shown in FIGS. 9 to 12. The rigid member 9 has a length of to 18 cm, desirably 8 to 14 cm., and a width of 3 to 7 cm. desirably 4 to 6 cm. The radius of curvature of its longitudinal section of FIG. 11 is 250 to 3,000 mm., desirably 500 to 1,500 mm., and the radius of curvature of its lateral section of FIG. 12 is 30 to 1,000 mm., desirably 50 to 500 mm. The core of this curved configuration permits the rigid portion to be closely fitted on the wrist and back of the hand, so that it is particularly useful in preventing the outward bending of the wrist. Such a core has never been known heretofore, and it is newly developed by the inventor. The rigid member may be made of any material so long as it has a rigidity enough to hold the wrist straight; for example, such well-known material as iron, or like metal such as steel and also various plastic materials may be effectively used.
The wrist band portion D joined to the rigid portion C has an important feature in its particular shape, which is shown in FIG. 2 in connection with the embodiment of FIGS. 2 to 4 and-in'FIG. 6 in connection with the embodiment of FIGS. 6 to 8, but slight changes in its shape and dimensions are allowed.
For purposes of better describing and more particularly pointing out the particular shape of the invention the following dimensions are specified,
In FIGS. 2 or 6, the cross sectional lines 55 and S 9-9, that bisect the rigid member and runs in a lengthwise direction, also serve as reference lines for specifying these preferred dimensions. h the shortest line that can be drawn from a point at the top, or finger end, of the rigid portion along the long axis of the rigid member and terminating at the center of fastening member 3, is 1.5 to 7 cm., preferably 2 to 5 cm. h the dimension running from the bottom, or arm end, junction of the rigid portion C with the wrist band portion D and terminating at a point corresponding to the bottom, or arm end, of the rigid portion, is 0.5 to 8 cm., preferably 1 to 5 cm. h the shortest line that can be drawn between a point on the line passing through the center point of fastening member 3 and perpendicular to reference line 55 or 9-9 and a point corresponding to the top of finger end, junction of the rigidportion C with the wrist band portion D, is 3 to 6 cm., preferably 4 to 5 cm.. h.,, the length of the junction between the rigid portion C and the wrist band portion D, is 4 to 7 cm., preferably 5 to 6 cm. 1, the shortest line running from a point on reference lines denominated 5-5 and 9-9 and terminating at a point corresponding to the junction of the rigid portion C with the wrist band portion D, is 7 to 12 cm., preferably 8 to 10 cm. Since the wrist band portion D has this particular shape, it will cover only the wrist portion even though the rigid portion D covers the back of the hand, and the palm will not be covered even if it is wound two or three turns. Also, since the width of the wrist band portion D is quite smallcompared to the longitudinal dimension of the rigid portion C, the wrist will not be absolutely held tight but can be bent inward to a slight extent (although it can not be bent outward). This is advantageous since considerable freedom is provided for the handling of the ball.
This wrist band portion is provided on the back side of its free end portion with a hook fastening member 8. Also, it is provided on the front side of its other tapered end portion joined to the rigid portion with a hook fastening member 6 and on the back side of the same with a pile fastening member 7.
The thumb band portion E also constitutes an important feature of the invention. By the provision of this thumb band portion E the rigid portion C can be positioned over the wrist and back of the hand irrespective of the size of the hand, and also it can be closely fitted and will not get loose even at the stem of the thumb. This thumb band portion E is provided on the back side of its top end with a pile fastening member 4 and on the left corner of its lower portion with a hook fastening member 5.
The thumb band portion has a shape as shown in FIGS. 2 or 6, where the angle a, the acute angle formed by the junction of the line drawn thru the center point of fastening member 4 and the center point of fastening member 5 and the line drawn thru the center point of fastening member 3 and the center point of fastening member 5, is 45 to 85, preferably 60 to As a fastening member Velcro, for example, may be suitably used.
To fit the bowlers wrist support according to the invention, the rigid portion C is placed on the back of the hand, and by winding the wrist band portion D over the inner side of the wrist the pile fastening member 7 on the back side of the tapered end portion of the wrist band portion and the hook fastening member 5 on the left corner of the lower portion of the thumb band portion are fastened to each other. Then, the wrist band portion D is wound over the front side of the rigid portion C and then over the inner side of the wrist, and it is fixed in position by fastening the hook fastening member 6 on the front side of the tapered end portion of the wrist band portion D and the pile fastening member 8 on the back side of the free end portion of the wrist band portion to each other. Finally, by winding the thumb band portion E around the thumb the pile fastening member 4 on the back of the free end portion of the thumb band portion is fastened to hook fastening member 3 on the upper portion of the rigid portion C.
When the bowlers wrist support according to the invention is fitted, the wrist will not bend outward and also it can be bent inward only to a slight extent, it is thus possible to give the ball a strong spinning action so as to obtain a pin action of high strike efficiency.
Also, when the bowlers wrist support is fitted by winding around the wrist twice with the wrist band portion D and fastening the thumb band portion E in conformity to the shape of the hand, the rigid portion C is closely fitted over the wrist and back of the hand, so that a constant supporting effect can be maintained without resulting in any loosening effects even if the game is continued for a long time.
It will be obvious to those skilled in the art that various changes may be made without departing from the scope of the invention and the invention is not to be considered limited to what is shown in the drawings and described in the specification.
