BASEBALL BAT CHOKE DEVICE Filed Sept. 20, 1966 ATTORA/EXST United States Patent 3,469,839 BASEBALL BAT CHOKE DEVICE Joseph A. Pietronuto, 3231 Lafayette Ave. 10465, and Robert Sands, 3235 Cambridge Ave. 10463, both of Bronx, NY.
Filed Sept. 20, 1966, Ser. No. 580,714 Int. Cl. A63]: 59/06, 69/00 US. Cl. 273-25 1 Claim ABSTRACT OF THE DISCLOSURE The present invention relates to baseball bat devices and more particularly to a bat device which will aid the batter in gripping the bat at a desired distance from its physical end or knob.
The practice of gripping a bat at a distance from its end is known as choking up and is a common practice among baseball players. As a result of choking up improved control may be obtained with a heavier and broader bat. When a batter chokes up, he grips the bat closer to its center of gravity, hence the moment created by the weight of the bat at its center of gravity is less than what it would be if the bat were gripped at its end or knob.
According to the present invention a simulated baseball bat end or knob is provided which is not the actual physical end of the bat. As a result, a batter may choke up to the same desired position each time he grips the bat.
Among the advantages gained through the use of the simulated bat knob or bat choke is that the batter will now be less likely to twist his wrist at the end of the swing. This practice of twisting the wrist is generally undesirable. Batters who choke up usually turn their wrists at the end of their swing as a natural reaction when following through and completing a swing since the end of the bat below the grip, if not held firmly, has a tendency to be directed towards the upper wrist or forearm of the batter, and the batter therefore twists his wrists to avoid contact of the bat end with his forearm.
The bat choke, by providing a simulated bat knob may prevent the twisting of the Wrist when batters choke up. Batters who do not choke up do not generally twist their wrists because the knob of the bat, by providing a firm grip and guide, prevents this from happening. In a similar manner, the simulated bat knob of the present invention will prevent this wrist twisting.
The bat choke may in addition, be utilized as a practice instrument to aid in the positioning of the batters hands during bunting. In bunting, the batters hand slides from the normal batting position at the end of the bat handle to a position near the broad portion or hitting area of a baseball bat. By placing the bat choke near the broad portion of the baseball bat, the bat choke acts as a guide stop for the batters hand as he changes his hands to the bunting position.
Although such novel feature or features believed to be characteristic of the invention are pointed out in the claim, the invention and the manner in which it may be carried out may be further understood by reference to p CC the description following and the accompanying drawmgs.
FIG. 1 is an elevation of the bat knob of the present invention installed on a baseball bat.
FIG. 2 is a cut view of the device of FIG. 1.
FIG. 3 is a cross sectional view of the bat knob of the present invention taken along lines 33 of FIG. 2.
FIG. 4 is a cut away detail of another embodiment of the bat choke of the present invention.
FIG. 5 is an end view of another embodiment of the present invention.
Referring now to the figures in greater detail, where like reference numbers denote like parts in the various figures.
The present invention comprises a simulated bat handle choke 1 which is fabricated preferably of a rubber, plastic or strong flexible substance with a knob portion 18 shaped in the manner of a baseball bat knob or end, said choke 1 including a vertical hollow portion 2 of generally cylindrical shape of an approximate diameter slightly smaller than that of a baseball bat handle 3.
The outer periphery 4 of said choke 1 includes a generally longitudinal slit or cleavage line 5 running through to the hollow portion 2 which enables the bat choke 1 to be opened so as to accommodate the various widths along the actual bat handle 3 and also to enable the bat choke 1 to be emplaced on the bat handle 3 by slipping the bat choke 1 over the actual bat handle knob 6 and be optional to the use of the bat.
Various gripping means may be utilized to secure the bat choke 1 to the bat handle 3 and. prevent the bat choke 1 from slipping along said bat handle 3 during use.
In one embodiment as shown in FIG. 5, the internal periphery of the hollow portion 2 comprises integral vertical or horizontal serrations in the shape of ridges 7 and cavities 8 which grip the bat handle 3 and are held by the natural tension reaction of the rubber or plastic bat choke 1 opposing the deformation resulting when the bat handle 3 is inserted through the hollow portion 2. This embodiment is not restricted in friction. means along the internal periphery of the hollow portion 2 to ridges 7 and cavities 8. Appropriate gripping means such as abrasive particles embedded into the internal periphery of said hollow portion 2 may also serve the gripping function.
Alternate gripping means may be used in conjunction with or as opposed to the natural tension acting through friction means.
In the preferred embodiment as shown in FIG. 2, a metal or plastic spring clip 10 of generally cylindrical shape conforming to that of the outer periphery 4 of the bat choke 1 is emplaced in declivity 11. in the bat choke 1. The spring clip 10 may contain a slit 12 so that it may expand with the bat choke 1 as said bat choke 1 is opened to accommodate the various widths along the bat handle 3 and also to enable said bat choke 1 to be emplaced on the bat handle 3 by slipping the bat choke 1 over the actual bat handle knob '6.
Two additional alternate gripping means are illustrated in FIG. 4, these may be used in conjunction with or as opposed to any other gripping means.
A generally cylindrical metal or plastic spring clip 13 is fabricated with the bat choke 1 and is so constructed that the clip 13 rests within the bat choke 1 in an internal area 14 of conforming size and shape. The spring clip 13 may contain a slit 15 so that it may expand with the bat choke 1 whenever such expansion is necessary.
Also shown in FIGURE 4 is an alternate gripping means which comprises an expandable band or ()-ring 16 which may be slid along the outer surface of the bat choke 1 into a groove 17 or declivity of conforming shape in the outer periphery 4, said groove 17 having a diameter exceeding the actual diameter of said ring 16. The O-ring 16 may be used in conjunction with or separate from other shown grip means.
In operation, the bat choke 1 is expanded and slipped over the actual bat knob 6. The choke 1 is then moved to a position along the bat handle 3 corresponding to the position where the batters hands are to rest when he chokes up.
The batter merely grips the bat as if the bat choke 1 were in fact, the actual knob of the bat. This procedure results in aiding a batter to choke up.
If the bat choke 1 is to be used to aid in bunting, the bat choke 1 is slid up the bat handle 3 to a position where the batters hand should grip the bat when bunting. The bat choke 1 then acts as an automatic guide stop for the batters hand.
The choke gives the batter the feeling of the end of the bat, as well as the support of the hands to prevent hands from slipping down from the choked position.
The terms and expressions which are employed are used as terms of description; it is recognized, though, that various modifications are possible within the scope of the invention claimed.
Having thus described certain forms of the invention in some detail, what is claimed is:
