The present invention relates to the bowling arts, and more specifically to advances in ball control in the bowling arts.
Bowling requires bowlers to hold a bowling ball, to accelerate the bowling ball towards a distant array of bowling pins by swinging the bowling ball, and to release the accelerated bowling ball in the direction of the pins. Success of each throw of the bowling ball requires that the bowling ball be carefully aimed at a pocket of the array, or towards specific pins, where some pins have already been knocked down. Bowling balls have sufficient weight so that maneuvering the bowling ball during release entails a number of problems. One problem is that the ball must be grasped with sufficient force to maintain manual control. Another is to avoid altering intended spin or “English” of the bowling ball and the trajectory of the bowling ball during release of grasp. Even if these objectives can be achieved, there remains the issue of injury to the hand. The thumb and fingers of a bowler are subject to chafing, forming of blisters and calluses, cuts, and other problems by contact with the thumbhole of the bowling ball. There remains a need in bowling for a device which eases the burden of supporting, aiming, and releasing a bowling ball.
The above noted problems are addressed by a bowling aid including a rigid sleeve enveloping the thumb of the bowler. The rigid sleeve encases that portion of the thumb occupying the thumbhole of a bowling ball, and may project outside the thumbhole. The rigid sleeve is worn on the thumb during the act of accelerating and releasing the bowling ball, and remains on the thumb throughout the entire throw.
The exterior of the rigid sleeve has low friction characteristics, so that the rigid sleeve slides along the thumbhole without significant resistance as the thumb and rigid sleeve pull away from the bowling ball during release.
Optionally, internal frictional characteristics of the rigid sleeve may be increased by use of a solid lining, such as a natural or synthetic rubber sheath which contacts the interior of the rigid sleeve, or by a tacky substance coating the interior of the rigid sleeve. A solid lining may also be used to improve fit of the thumb to the interior of the rigid sleeve.
Use of the rigid sleeve, with or without frictional enhancement of the interior surface, overcomes the manual effort of grasping a bowling ball without such a rigid sleeve. Also, the thumb is protected from abrasion, pinching, and other causes of injury to the thumb. More specifically, the sleeve eliminates injured thumb knuckles, sides, and webbing of the thumb. Elimination of effort and injury free the bowler from distractions which otherwise tend to distort the ideal motion of the hand when releasing the bowling ball from manual grasp. This improves the ability of a bowler to control the ball, at a conscious level, a subconscious level, or both. Ball accuracy, ball speed and revolution rate, and hence favorable bowling results are thereby enhanced.
Because of reduced attention and effort required when releasing a bowling ball, consistency of control and effort from one swing and release of a bowling ball to subsequent swings and releases is improved.
The Applicant has from experience found that when releasing or launching a bowling ball, a greater degree of control of its movement may be exercised by first quickly releasing the thumb from the thumbhole during the swinging of the ball prior to the launching of the same while permitting the two fingers to dwell in the finger holes until the ball reaches a more advanced position. By first quickly releasing the thumb while the two fingers remain in the finger holes, the rotation motion of the ball may be regulated at its time of launching to more accurately direct the ball toward the particular location where it is desired to strike the pins, thus making it possible to substantially increase effectiveness of the throw or launch. Use of the novel sleeve results in effortless thumb release, without distortion of the trajectory of the bowling ball, as though the thumb were not in a hole in the bowling ball. Among other effects, a bowler will be able to generate ball rotation rates similar to competitors who do not insert the thumb into the ball.
In a further improvement, a bowling ball may be provided with a positive axis point indicator.
In another improvement, the rigid sleeve may bear raised indicia.
It is an object to provide improved elements and arrangements thereof by apparatus for the purposes described which is inexpensive, dependable, and fully effective in accomplishing its intended purposes.
These and other objects will become readily apparent upon further review of the following specification and drawings.
Various objects, features, and attendant advantages of the disclosure will become more fully appreciated as the same becomes better understood when considered in conjunction with the accompanying drawings, in which like reference characters designate the same or similar parts throughout the several views, and wherein:
Referring first to
In certain exemplary embodiments, rigid sleeve 100 may comprise a length of tubing material such as polyvinyl chloride (PVC) tubing. PVC tubing of the type commonly sold at retail facilities/stores for household plumbing is suitable, although furniture grade PVC tubing is currently regarded as having desirable additional properties. In exemplary embodiments, these properties include strength, ultraviolet radiation resistance, commercial availability in diverse colors, low or no toxicity, and glossy surface finish. The latter characteristic may result in a quicker release from a bowler's grasp, compared to other grades of PVC tubing. This type of product also exhibits suitable friction characteristics for the outside surface 108 of rigid sleeve 100. The friction characteristics are those that would avoid altering the trajectory of a bowling ball 10 or spin or rotation characteristics of bowling ball 10 when throwing or releasing bowling ball 10 from the grasp of the bowler.
Referring particularly to
It should be noted that in the aforementioned exemplary embodiment first and second rounded ends 18 are rounded both at the exterior of rigid sleeve 100 and also at the interior thereof. This minimizes frictional engagement of edges of rigid sleeve 100 when a bowler inserts his thumb 2 into the bowling aid. In one exemplary implementation of

The above described items may be utilized in a method of enhancing ball control by a bowler when swinging and releasing bowling ball 10. In one example of the method of enhancing ball control by the bowler when swinging and releasing the bowling ball in the grip of the bowler comprises lining a thumbhole of the bowling ball with an annular rigid hole liner (e.g., rigid sleeve 100) having an external slide surface 108 slidably engaging a surface of thumbhole 8, wherein the annular rigid hole liner is sufficiently rigid to avoid deformation when subjected to contact with hand 4 of the bowler while bowling, and is dimensioned and configured to fit in close cooperation with and slide readily along thumbhole 8 of bowling ball 10. The method further comprises slidably withdrawing the annular rigid hole liner from thumbhole 8 when the ball (i.e., bowling ball 10) is released from the grip of the bowler.
The method may further comprise coating at least a portion of an interior of the annular rigid hole liner (e.g., interior surface 116 of rigid sleeve 100) with tacky substance 112 prior to swinging and releasing bowling ball 10.
The method optionally further comprises reducing interior diameter 104 of at least a portion of the annular rigid hole liner (rigid sleeve 100) prior to swinging and releasing bowling ball 10.
The method further comprises rounding at least a portion of at least one end of the annular rigid hole liner (e.g., resulting in rounded ends 18) prior to swinging and releasing bowling ball 10.
