7 Claims, 6 Drawing Figures BOWLING GRIP EXERCISE DEVICE The present invention is generally related to exercising devices and, more particularly, to a device for exercising muscles in a manner which simulates, in part, the acts of bowling.

In the past, the proper development of bowling skills required a bowler to adhere to a regular training schedule including muct time spent each day at a bowling alley. Such a time consuming training schedule was impractical, if not impossible for the amateur or once-aweek bowler to adhere to on a regular basis. As a result, the once-a-week bowler seldom achieved his full poten tial. I-Iis finger, wrist, and arm muscles tended to relax between weekly bowling sessions, such that he could not maintain satisfactory ball control.

Therefore, it is an object of the present invention to provide a novel exercising device for bowlers which is effective in conditioning the thumb, finger, wrist and arm muscles with regular use for a relatively short period of time each day, whereby a bowler may improve or maintain his ball control skills.

It is another object of the present invention to provide a unique bowling exercise device which is adapted to accommodate the four fingers of a user in squeezing relationship with the thumb which is flexed against the forces of a compression spring or the like, whereby the acts of bowling ball grip and manipulation are simulated to improve or maintain one s ball control skills.

I A further object of the present invention is to provide a versatile bowling exercise device including a spring mechanism or the like which may be selectively positioned in a main body or housing to accommodate different hand sizes for simulating the maniuplation of a ten-pin type bowling ball.

It is still another object of the present invention to I 13 and a peripheral edge portion 14 defined by a relaprovide a novel bowling exercise device which is comprised of a small number of moving parts, is rugged, durable, long lasting, and relatively inexpensive to manufacture.

These together with other objects and advantages which will become subsequently apparent residein the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout- FIG. 1 is a perspective view of the bowling exercise device of the present invention.

FIG. 2 is a perspective view of the bowling exercise device of the present invention with a phantom view of a user's hand in operative engagement therewith.

FIG. 3 is an exploded perspective view of the'spring mechanism associated with the present invention.

FIG. 4 is a front elevation of the bowling exercise device illustrated in FIG. I, with a phantom view of a user's hand in operative engagement therewith.

FIG. 5 is a sectional view taken along section 5--5 of FIG. 4.

FIG. 6 is a sectional view taken along section 6-6 of FIG. 4.

Referring now, more particularly, to FIGS. 1 and 2 of the drawings, the bowling exercise device of the present invention is generally indicated by the numeral 10 and includes a relatively rigid body or housing 12 which is of thin, generally planar configuration and is of a size which may be easily held in ones hand. Preferably, the housing is formed from steel, plastic, or similar rigid materials and is provided with a generally planar wall tively smooth surface extending around substantially the entire housing. The lower section of the peripheral edge portion is provided with a pair of finger-receiving

indetations

16 and 18 which are adapted to receive a users no. two and no. three fingers, respectively. In addition, a pair of oppositely disposed, generally

planar extension areas

17 and 19 are integral with the housing and adapted to accommodate a users first and fourth fingers, respectively, as illustrated in FIG. 4.

Preferably, the housing is opened on one side and is of relatively thin walled construction, thereby providing a generally hollow configuration, as best shown in FIG. 2. An upper section of the peripheral edge portion 14 is provided with a downwardly extending slot generally indicated by the numeral 20 oppositely disposed of the finger-receiving indetations l6 and 18. The slot is of generally elongated, rectangular configuration and is adapted to mount a spring mechanism 22 therein by way of mounting apertures 24. The mounting apertures are located in a pair of oppositely disposed, generally

parallel flange portions

26 and 28 integral with the housing 12. The mounting apertures are arranged in two columns, with the apertures of each column being vertically spaced from each other for the purposes of adjustment, as hereinafter explained.

With reference to FIGS. 3-6 of the drawings, it will be observed that the spring mechanism 22 is comprised of a spring seat member or housing 30 of generally rectangular configuration and being provided with threaded stud members 32 extending outwardly from one side thereof. The spring seat member is mounted to main housing 12 in stationary relationship thereto by way of threaded nuts 34, with. studs 32 extending through corresponding aligned mounting apertures 24. A movable'thumb-receiving member 36 is reciprocally mounted in slot 20 and is connected to spring seat member 30 by way of a coil compression spring 38, or similar biasing means. The thumb-receiving member is of generally rectangular configuration and is of lesser dimension than the corresponding interior dimensions of the spring seat member, such that it may be slidably received in the spring seat member for reciprocation therewith. Preferably, the opposite end convolutions of the coil compression spring are welded, or otherwise fastened, to the spring seat member 30 and thumb-' receiving member 36 as indicated at 40 and 42 in FIG.

As mentioned above, the purpose of the bowling exercise device of the present invention is to exercise the thumb, fingers, wrist, and arm muscles in a manner which closely simulates the acts of bowling. The gripping and maneuvering of a l0-pin type of bowling ball is of prime importance to the success or failure of each bowl. When utilizing the device of the present inven-- 'tion, a user grips the housing in a manner illustrated in FIGS. 2 and 4, applying thumb pressure to the thumb- 7 receiving member 36.

fourth fingers rest against and are generally parallel to I

extension areas

17 and 19, the second and third fingers being bent slightly as if gripping a bowling ball. This exercise is repeated for about minutes several times daily. This exercising strengthens and conditions the muscles which are utilized in gripping a ten-pin type bowling ball. As the thumb and fingers are being exercised in the above described manner, the user should move his wrist in various directions relative to his forearm. In addition, the user may find it advantageous to simulate the other motions of bowling, such as stride and delivery while gripping the exercising device. With daily use, most bowlers will maintain or improve their ball control skills, such that they may concentrate on their timing and execution of delivery.

Since the finger and thumb holes of the 10-pin type bowling balls are sized and positioned to fit the individuals strength and hand size, it is esential that the exercising device provide approximately the same spatial arrangement for the fingers and thumb during exercising. This is achieved by adjusting the position of the spring seat member relative to the finger-receiving indentations. The threaded nuts 34 may be easily removed and the stud members 32 fitted into the appropriate mounting apertures 24 to assure proper spacing between the thumb-receiving member 36 and fingerreceiving indetations when the coil compression spring 38 is fully depressed. Thus, the bowling exercise device of the present invention accommodates various hand sizes and provides a finger-thumb spatial relationship approximating that of the users lO-pin ball.

It will be appreciated that the exercising device of the present invention may be provided with fastening means other than the studs and nuts illustrated in the drawings. Furthermore, the use of resilient means other than the coil compression spring is deemed to fall within the scope of the present invention. Also, minor changes in the configuration of the main housing may be provided so long as the spatial relationship between the fingers and thumb-receiving areas of the device is maintained. Since the device includes a relatively small number of moving parts, each of simple construction, it is economical to manufacture, such taht it may be sold within the financial means of most bowling enthusiasts.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
