Description
May 29, 1962 J. ENGAN ARM LOCK ARRANGEMENT Filed Aug. 8, 1960 INVENTOR. JOHN E/VG'A/V 14 T TOENE Y United States Patent 3,036,831 ARM LOCK ARRANGENIENT John Engan, 4914 7th Ave., Brooklyn, NY. Filed Aug. 8, 1960, Ser. No. 47,986 4 Claims. (Cl. 273-54) This invention relates to a device used in the sport of bowling, and more particularly, to an arm support arrangement to insure proper delivery of a bowling ball.
Bowling has become one of the most popular indoor sports. The secret of bowlings universal appeal is that it can be enjoyed by all regardless of sex, age, or condition. In the past ten years, bowling establishments have undergone tremendous changes. The development of automatic pin setters, foul-line detectors, electronic scoreboards, and many other electromechanical devices have been instrumental in revolutionizing bowling as well as increasing its popularity.
Proficiency in bowling is therefore a common goal and the prime purpose of this invention is to improve the proficiency of all its participants. One of the essential factors to consider in improving ones game of bowling is the proper delivery of the bowling ball. A delivery in bowling is defined as the position of the body prior to release of the bowling ball. The achievement of a good delivery depends primarily on the control of the bowlers hand, wrist, and forearm.
To this end, my invention consists of a device which will considerably aid the bowler in delivering and controlling the ball more efficiently and efiectively.
In order to achieve a good delivery, footwork, bowlingball grip, and arm swing must work together and be synchronized in perfect harmony. There are four basic types of delivery which, depending on the settings of the bowling pins, may be utilized. They are as follows:
(1) The Straight Ball (2) The Hook Ball (3) The Curve Ball (4) The Backup Ball A bowling ball ordinarily has three radial openings. To throw the straight ball ones thumb and fingers should form a V with the thumb pointing straight up in a relative position, which corresponds to the 12 oclock setting of an imaginary clock. The thumb should be positioned directly above the fingers and the wrist should be straight. The thumb must remain in the 12 oclock position throughout the entire delivery. The wrist should be kept straight and in line with the forearm throughout the entire swing. There should be no twisting motion of the wrist.
The biggest problem facing a bowler is to prevent his wrist from twisting and to confine his hand and forearm to movement in a given plane. This movement should be in the arc corresponding to the future travel direction of the ball. Utilization of the present invention is suggested as an aid in preventing any twisting motion of the hand, arm, or wrist upon delivery of the ball. It must be remembered that as the ball leaves the fingers, a spin is automatically imparted so that the ball rolls freely and will not skid towards the pins. A properly delivered bowling ball has a double motion, namely sliding and revolving. It slides towards the pins in the direction in which it is released and it revolves in the direc tion given to it by the position of the fingers. After the ball has slid a certain distance the force of its slide is decreased by friction. Then the rotation of the ball overcomes the force of the slide and the ball begins to curve in the direction of rotation.
The hook ball is delivered in a manner similar to that of the straight ball. About two-thirds of the way down the alley, the hook ball veers sharply to the left toward 3,fi36,83l Patented May 29, 1962 the pins. As in the straight ball delivery, the fingers and thumb make a V, the sole difference being that the thumb now points at the 10 or 11 oclock position instead of the straight up 12 oclock position. Since the thumb leaves the ball first, the fingers that remain in the ball give the ball a counterclockwise lift and consequently a spin in that direction. It is essential to realize that the wrist plays no part at all in this spin and that it should be kept in a straight line with the forearm at all times.
To throw a curve ball, one simply moves the wrist position still further in a counter-clockwise position. Here the thumb will be pointing to the 9 oclock position.
In throwing the backup ball, the ball is delivered with the thumb pointing toward the 1 or 2 oclock position so that the ball leaves the hand with a clockwise motion to the right instead of the normal spin to the left. This type of delivery is used when attemptingto make difiicult spares. I
Thus, it must be noted, that no matterwhich bowling delivery is desired, the wrist is not to be turned or twisted during the instant of release of the ball, as the desired delivery is solely dependent on the position of the thumb and finers in the radial openings. No twisting motion of the wrist is needed in order to impart a hook or curve to a bowling ball. If the Wrist or arm is turned over so slightly on delivery, the result will be a spinning ball revolving on the bottom instead of on its full diameter. Such a ball has less grip on the alley, its accuracy is extremely diflicult to control, and it is easily deflected by the plus it hits.
An object of the present invention therefore is to provide a novel form of an arm support arrangement which will insure the proper delivery of a bowling ball.
Another object of the present invention .is to provide an arm support arrangement which will control the move ment of the hand with respect to the bowlers forearm.
Still another object of this invention is to prevent unnecessary twisting motion of the bowlers wrist and restrain the movement of the arm to a given plane.
A feature of this invention is the utilization of an arm support arrangement used primarily in the sport of bowling comprising a bar, and a pair of adjustable clamping members disposed at opposite ends of said bar and normal thereto. One of said clamping members is adapted to encircle the forearm of the wearer so as to maintain it in a predetermined position with respect to said bar. The other of said clamping members is adapted to encircle the hand of the wearer including the thumb crotch so as to maintain it in a predetermined position with respect to said bar. The bar has a lateral profile which corresponds to the profile of the palm.
The above mentioned and other features and objects of this invention will become more apparent by reference to the following description taken in conjunction with the accompanying drawing in which FIG. 1 represents a perspective view of the arm support arrangement applied to the hand and arm of a wearer; and
FIG. 2 is a detailed perspective of the arm support arrangement.
Referring more specifically to FIG. 1, it is seen that the invention comprises an arm support arrangement disposed about the of a wearer for maintaining the wrist in a predetermined position. This arrangement consists of a lateral bar 1 having an offset 2 in the direction of the length of the bar and which oifset conforms to the lateral profile of the palm 3, and wrist 4. Attached to the lateral bar 1 at opposite ends are a pair of clamping members 6 and 7, for the forearm and wrist respectively. The hand and forearm are passed through clamping members 6 and 7. The clamping members consist of straps 12 and 13 which cooperate with members 6 and 7, re-
spectively, and fitted about the forearm and hand of the wearer in the manner illustrated in FIG. 1. Strap 7 is fitted in the thumb crotch of the wearer. Buckles 8 and 9, or any other suit-able adjustable fastening means engage the ends of straps 12 and 13 (see FIG. 2) respectively, as the straps are tied and fitted to the size and shape of the wearers arm and hand. Sponge rubber pads 10 and 11 are used to relieve the pressure of the straps 12 and 13 about the arm and hand respectively. It is also noted that the straps 12 and 13, and the pads 10 and 11 are riveted at 14 and 15 to the bar 1. Any other suitable form of attaching means may be utilized instead of rivets to attach the straps and pads to the bar.
This device after being applied to the arm of a bowler will prevent the bowler from twisting his wrist and maintain it in a straight line with the forearm at all In this way, a bowler will only have to shift the position of his thumb and fingers to obtain optimum accuracy and control of the movement of the ball. Such an arm support arrangement will enable any bowler to perfect his delivery and more efiectively control the accuracy of movement of the bowling ball which will result in a substantial improvement in his bowling game.
