Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention, regardless of time and place,
This is related to a pitching practice tool that allows one person to practice pitching alone.

[0002]

2. Description of the Related Art Up to now, in the history of the baseball world, a pitching training tool which is the same as or similar to that of the present invention has not been found on the market. Speaking strongly, it has been common practice to practice holding a towel in your hand like a ball and swinging the towel down.

[0003]

The above-mentioned conventional method of performing pitching practice using a towel has the following drawbacks. First of all, because you can not feel the ball at your fingertips, "straight ball" that technically masters your fingertips and wrists and throws,
I can't understand the subtle twisting of changing curves such as "curve" and "slider". That is, it is impossible to practice from the pitching motion to get the position where the ball is released from the fingertip, which is important for the control applied when lowering the raised arm.

Further, with a towel, since the "beans" and "octopuses" that are important for pitchers when the ball is released from the fingertip cannot be formed, the fingertip does not solidify and it is not possible to practice pitching of a speed ball or a stretched ball. The present invention, regardless of time and place, for example, at night, in the garden or room alone, with the same feeling as when throwing a catcher to the opponent, straight ball,
It is an object of the present invention to provide a pitching training tool capable of practicing pitching such as a changing ball.

[0005]

SUMMARY OF THE INVENTION The present invention uses a synthetic fiber thread or the like which is strong and has relatively little stretchability, and has a depth at least about twice that of the palm, and the palm can freely rotate about the wrist. Having a product, and the mesh of which is half or less than the diameter of a baseball ball, is braided using a mesh bag knitting machine, and its shape is drawn and knitted near the bag mouth so as to form an ice bag shape, The bag mouth is knitted so that the ball can be freely moved in and out. Next, in order to detachably fasten the bag mouth to the wrist, a fastening belt longer than the perimeter of the bag mouth is attached to the outer peripheral surface of the bag mouth near the edge of the bag to complete the intended pitching practice tool. To do.

Further, it is possible to form a pitching practice tool having substantially the same shape as the net bag by a sewing means using an appropriate fiber cloth. Furthermore, as a special cloth, for example, a lace fabric woven by a curtain lace machine can be used to provide a pitching training tool substantially equivalent to a net bag by the sewing means.

[0007]

In order to practice pitching using the pitching training tool of the present invention, both the net bag and the cloth bag are put into the bag through the bag mouth, and the bag is fixed to the wrist with the fastening belt. Then, he grabs the ball in the bag, throws it, and throws it as if he were throwing it toward the catcher. (See FIG. 3) Of course, the bag itself catches the ball separated from the fingertip, so that the ball can be repeatedly and immediately thrown. You can practice pitching in the room, in the garden, or at any time of the day or night.

If a mesh bag or a cloth bag made of lace is used, the pitcher himself can obtain the subtle movements of a straight ball and a changing ball, such as how to grip the ball and the twist of the fingers and wrist. Because you can see through, you can teach as if you were practicing at a stadium. In addition, the usual cloth bag has the effect of protecting the fingertips and wrists, which are the most important for pitchers, when practicing pitching outdoors when the weather is rainy and snowy, or when the temperature is particularly low.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a pitching practice tool of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a pitching training tool completed by attaching a fastening belt 3 around the outer peripheral surface edge of the bag mouth 2 of a net bag 1 knitted by a net bag knitting machine (not shown). 4 is a perspective view of a pitching practice tool which is also made of the cloth bag 1a, and FIG. 3 is an explanatory view of a usage state for practicing pitching in the cloth bag 1a which is formed of a lace material in which a watermark pattern is continuously repeated. FIG. 9 is an explanatory view showing a state in which a towel 6 is conventionally used for pitching practice.

In FIG. 1, a net bag 1 is made of polyester filament fibers, for example, and is knitted in the shape of an ice bag using a commonly used net bag knitting machine. The knitting is finished by knitting, forming a bag mouth having a diameter that allows the user to freely move in and out while holding the ball in his hand. Then, a cloth or leather belt having a buckle attached to one end thereof is fixed to the outer peripheral surface of the bag mouth 2 with an adhesive near the edge, and the other end of the belt is free to be inserted into the buckle and fastened. Leave it in a state.

The fastening belt 3 attached to the outer peripheral edge of the bag mouth 2 has a tape formed of Velcro fasteners (trademark name Velcro tape) on the back side of the belt free portion 3a at the other end and the outer peripheral surface side. Most convenient to attach. In this case, the belt-free portion 3a needs to have a length of at least half or more of the outer peripheral surface of the bag mouth after being folded back at the buckle portion, and the fastening belt 3 is preferably made of cloth, and the female part of the velcro tape is the bag mouth portion. The male part may be attached to the belt-free part on the outer peripheral surface.

The mesh of the mesh bag 1 is preferably 3.5 mm or less, and the inner volume of the bag is about twice the depth of the palm, that is, 35 to 40 mm in depth, and the maximum width portion has a diameter of 20. 25 to 25
The size of the kame is suitable. The material of the net may be any of natural fiber, chemical fiber or synthetic fiber, but in consideration of strength, elongation and the like, polyester long-fiber yarn having a thickness of about 1 knot is suitable. Further, the bag mouth 2 may have a diameter of about 12 to 15 mm so that the hand holding the ball can freely take it in and out.

The pitching practice tool of the present invention comprising a cloth bag 1a formed by using a normal cloth or lace is generally formed by sewing means as follows in order to form the net bag shape. First, draw a shape in which the mesh bag 1 is folded in two on a pattern paper, calculate the size divided into an appropriate number in the longitudinal direction with reference to this drawing, and add a nuisiro or a halishiro to the edge of the divided piece. Thus, an appropriate number of pieces of cloth are cut.

As the cutting cloth is sequentially sewn with a sewing machine or joined using an appropriate adhesive, the cutting cloth is gradually formed into a bag shape. Finally, when the bag is turned upside down, it becomes a cloth bag similar to a net bag, and the end of the bag mouth 2 is folded inward and sewn or joined to complete a temporary cloth bag, so that the fastening belt is attached to the outer peripheral edge of the bag mouth 2. 3 is sewn or adhered to complete the pitching practice tool of the present invention including the cloth bag 1a shown in FIGS.

INDUSTRIAL APPLICABILITY The pitching training tool according to the present invention has the following good results, which cannot be compared with the training effect obtained by observing a conventional towel as a ball. You can practice pitching by yourself at any time and place, especially at night in the garden or room of your house while enjoying the feel of pitching from the mound. And because you can use the ball to pitch, you can practice straightballs, curves, shoots, sliders, knuckles, etc. with subtle fingers and wrists, changing balls can be remembered, and the bag catches all balls away from your hand. . Furthermore, in the feeling of throwing a catcher opponent,
It is possible to practice the position where the ball is released from the fingertip where the pitcher's most important control is applied, and the effect is doubled especially when practiced in front of a mirror.

Many pitchers throw out a lot of pitchers and seek "beans" and "octopuses" at their fingertips, which are their pride.
The pitching training tool of the present invention can easily achieve its purpose,
In addition, it is possible to improve speed and ball growth. Since the mesh bag 1 and the lace cloth bag 1a can be seen through from the outside of the bag, such as how to grasp the ball, the pitcher can observe the inside of the bag, and the coach can easily instruct and the coach can improve quickly. The cloth bag 1a (excluding lace fabrics) has an effect of protecting important pitchers and wrists of pitchers when practicing outdoors in the wind, rain or snow in winter. The pitching training tool of the present invention is extremely low in manufacturing cost and can be expected to be widely used.
