Description

  The present invention relates to an exercise device used for practicing ball games such as baseball and a manufacturing method thereof. More specifically, the load according to the level of the user such as age and skill level of pitching technology is given, and safety during practice The present invention relates to an exercise exercise tool with improved performance and a method for manufacturing the same.

  In many ball games including baseball, it is required to strengthen the shoulder muscles.

  Therefore, in baseball practice, for example, throwing hundreds of balls and a hard baseball are performed every day in order to train the shoulder muscles.

  By the way, it is known that the shoulder muscle has an outer muscle in which changes due to training are visible, and an inner muscle in which the changes are difficult to see even after training. In particular, the inner muscle is a muscle that supports the shoulder joint so that it does not come off, so it is important to strengthen the inner muscle to train the inner muscle.

  However, even if the outer muscle can be trained in the severe pitching practice as described above, the inner muscle that is difficult to see may be consumed, which may lead to a shoulder failure. In particular, in the case of boys with undeveloped shoulders, the risk is higher.

  Also, in order to acquire the correct throwing form, it is important to always practice throwing. However, throwing practice usually requires an opponent to receive the thrown ball, so it cannot be practiced at any time.

Therefore, the inventor of the present application has developed an exercise exercise tool for solving such a problem and has applied for the following utility model registration.
Utility Model Registration Application 2005-000602 (Registration No. 3110296)

    In this way, the above exercise exercise tool makes it possible to easily reinforce shoulder muscles at any time and practice wearing the correct throwing form.

  However, as the above exercise equipment is widely used from beginners who have just begun sports to advanced experts such as professional baseball players, exercise equipment corresponding to the strength of the shoulder muscles is required. became.

  The object of the present invention is to provide a highly safe exercise exercise tool capable of forming a correct throwing form and training muscles such as shoulders in a short time by appropriately responding to the skill level of the user and the strength of the shoulder muscles. And providing a manufacturing method thereof.

  The invention of the present application is a flexible rod-shaped exercise exercise tool having a weight at the tip, comprising a weight whose overall shape is a cylinder, an inner diameter larger than the outer diameter of the cylinder of the weight, and a heat shrinkable material. And the weight is fixed to the flexible rod-like body by the heat-shrinkable cylindrical member, and solves the above problems.

  When the length of the fixing cylindrical member is longer than the length of the first cylindrical member and covers the entire cylindrical member for the weight, it is supported from both the front end and the rear end. , It will be stronger.

  The invention of the present application is a flexible rod-shaped exercise exercise tool having a weight at the tip, comprising a weight having a cylindrical member at one end, and an inner diameter larger than the outer diameter of the cylindrical member of the weight, A cylindrical member for fixing made of heat-shrinkable material, and the cylindrical member for weight is fixed to the flexible rod-like member by the fixing cylindrical member, and solves the above-mentioned problems To do.

  Furthermore, one end of the grip portion fitted to the rear end of the rod-shaped body is fixed to the flexible rod-shaped body by a fixing cylindrical member made of a heat-shrinkable material, and the above problem is solved.

  When the rod-shaped body is formed of 6-nylon-based resin, flexibility and elasticity can be obtained. However, the rod-shaped body may be manufactured using other materials exhibiting flexibility and elasticity. In addition, an ethylene / propylene rubber heat shrinkable tube may be used as the fixing cylindrical member that is thermally shrunk, but other heat shrinkable materials may be used.

  In this specification and claims, the cylindrical shape of the cylindrical member means that the substantial shape is a cylinder, and in addition to a complete cylinder, a side surface is notched. It may be a cylindrical member. Such a structure is convenient for attachment because it can be fitted to a rod-shaped body with the side cuts widened.

  According to the present invention, there is provided a method for manufacturing a flexible rod-shaped exercise exercise tool having a weight at a tip thereof, a step of preparing a flexible rod-shaped member, a cylindrical member for a weight, or an end portion of the flexible rod-shaped body. A step of fitting a weight provided with a cylindrical member to the rod, and a step of fitting a fixing cylindrical member made of a heat-shrinkable material to the rod-like body, the inner diameter being larger than the outer diameter of the cylindrical member And heat-treating the fixing cylindrical member, and fixing the cylindrical member for the weight or the cylindrical member at the end of the weight to the flexible rod-like body by thermal contraction of the cylindrical member. To solve the above problems.

  According to the exercise tool of the present invention, since the weight is provided at the tip of the rod-shaped body, the load applied to the shoulder and the arm when the arm is shaken is appropriately increased. Further, since the rotational moment of the rod-shaped body also increases, the bending of the rod-shaped body increases. When the rod-like body is shaken off, the rod-like body is pulled by the inertial force of the weight at the tip. As a result, the pitcher's arms and shoulders are also pulled, so compared to a conventional rod-shaped body that does not have a weight attached, the so-called “swing-out” is improved, and a feeling similar to that when a ball is thrown can be obtained. .

  In addition, since the weight is fixed to the rod-shaped body via the cylindrical member made of the heat shrinkable material, it is possible to prevent the weight from coming off the rod-shaped body when the rod-shaped body is shaken.

  According to the method for manufacturing an exercise device of the present invention, both a weight and a cylindrical member for fixing the weight can be easily fitted to the rod-shaped body, and the weight can be simply formed by heating the cylindrical member. Therefore, it can be manufactured very easily as a whole.

  Hereinafter, an embodiment of an exercise training tool of the present invention will be described with reference to FIGS. FIG. 1 shows the appearance of an exercise training tool according to an embodiment of the present invention, FIG. 2 shows members constituting the exercise training tool, FIG. 3 shows a method for manufacturing the exercise training tool according to the embodiment of the present invention, FIG. 4 shows the types of weights of the exercise practice tool according to the embodiment of the present invention, and FIGS. 5 to 8 show the state where the pitching practice is performed using the exercise practice tool according to the embodiment of the present invention. 9 shows an exercise exercise tool according to another embodiment.

(1) Configuration of Exercise Exercise Tool The overall length of the exercise exercise tool shown in FIG. 1 is 51.5 cm. The length may be appropriately changed as long as the pitching operation shown in FIGS. 5 to 8 is not hindered, but is preferably 40 cm or more and 65 cm or less. The full length of the exercise exercise tool here means a length not including the strap 6.

  The total weight of the exercise equipment is about 120 g. This corresponds to the weight of the baseball for the baseball (141 to 142 g), but if the total weight of the exercise equipment is heavier than 250 g, the inner muscle of the shoulder is consumed, causing a shoulder failure. Also, when the total weight of the exercise equipment is lighter than 100 g, it may cause a shoulder failure. The specific weight of the exercise equipment needs to be appropriately selected according to the development of the shoulder muscles. For example, when a minor such as a boy whose shoulder muscles are underdeveloped, the weight of the exercise exercise tool is preferably 100 g or more and less than the weight of the official baseball ball. On the other hand, when an adult whose shoulder muscles have developed to some extent is used, the weight of the exercise exercise tool is made to be not less than the weight of the baseball ball and not more than 250 g. It becomes possible to train.

  As shown in FIGS. 1 and 2, the exercise exercise tool according to the embodiment of the present invention is a rod-shaped body 1, a weight 2, a grip portion 3, and a cylindrical member heat shrinkable tube 4 that fixes the weight 2 to the rod-shaped body 1. And a heat-shrinkable tube 5 of a cylindrical member to which the grip portion 3 is fixed and attached to the rod-like body 1.

  The rod-shaped body 1 is made of a nylon resin such as 6 nylon. Since a nylon resin such as 6 nylon is elastic, when a rod-shaped body is formed of such a resin, an appropriate deflection (flexibility) is obtained when the rod is shaken. The rod-shaped body 1 has a circular cross section and a diameter of 14 mm, but the thickness can be changed as appropriate. From the viewpoint of ease of swinging, 12.0 mm to 16 mm is desirable.

  A cylindrical weight 2 is attached to the tip of the rod-like body 1. Since the weight 2 has a cylindrical shape, it can be easily fitted from one end of the rod-shaped body. Therefore, it is desirable that the inner diameter of the weight 2 is slightly larger than the outer diameter of the rod-like body 1.

  The heat shrinkable tube 4 is a heat shrinkable tube (shrinkage temperature of 130 ° C., shrinkage rate 50%) made of ethylene / propylene rubber. Such heat-shrinkable tubes are commercially available, and other heat-shrinkable tubes such as silicone heat-shrinkable tubes may be used.

  As shown in FIG. 1, both ends of the heat-shrinkable tube 4 are contracted and are in close contact with the rod-shaped body 1. For this reason, the weight 2 is completely hidden by the heat-shrinkable tube 4 in FIG.

  Reference numeral 3 denotes a grip portion attached to the other end of the rod-shaped body 1. Since the grip portion 3 plays a role as an anti-slip as well as a known golf club grip, a rubber material used for a golf club may be used. However, since the rod-like body 1 is shaken with one hand (right hand or left hand), its length is shorter than the grip of the golf club.

  Reference numeral 5 denotes a heat shrinkable tube made of cylindrical ethylene / propylene rubber for fixing the grip portion 3 to the rod-like body 1. In this case, the heat-shrinkable tube secures only one end of the grip portion 3 to the rod-shaped body 1. Therefore, the length may be shorter than that of the heat shrinkable tube 4 used for completely covering the weight 2.

(2) Method for Manufacturing Exercise Exercise Tool Next, a method for manufacturing an exercise exercise tool according to an embodiment of the present invention will be described with reference to FIG. First, as shown in FIG. 3A, a 6 nylon rod-shaped body 1 is prepared. Next, as shown in FIG. 3 (b), the weight 2 is fitted from one end of the rod-like body 1 and positioned near the tip, and the grip portion 3 is fitted to the rod-like body 1 from the other end.

  Next, as shown in FIG. 3 (c), heat shrinkable tubes 4 and 5 made of ethylene / propylene rubber are inserted from one end of the rod-like body 1, and the position is set so that the weight 2 is completely covered by the tube 4. The position is set so that one end of the grip portion 3 is covered with the tube 5. Thereafter, when the end of the tube 4 is heat-treated at about 150 ° C., the heated tube 4 is gradually contracted and is brought into close contact with the rod-shaped body 1. As a result, the weight 2 is completely covered with the contracted tube and is fixed to the rod-like body 1. This state is maintained even after the temperature drops. Thus, since the weight 2 is strongly fixed by the heat shrinkable tube, it is possible to prevent the weight 2 from coming out of the rod-like body 1 when the rod-like body 1 is shaken.

  Moreover, since the attachment position of the weight 2 and the tube 4 to which the weight 2 is attached can be selected as appropriate, the magnitude of the rotational moment of the rod-like body 1 by the weight 2 can be adjusted.

  FIG. 4 shows some specific examples of the weight 2 having different weights. The example shown in FIG. 4A is a rubber weight 2a having a length of 1.0 cm and a weight of 2 grams. Further, the length of the tube 4a covering the weight at this time is 2.5 cm.

  Similarly, an example shown in FIG. 4B is a rubber weight 2b having a weight of 5 grams, a length of 2.5 cm, and a length of the tube 4b covering the weight is 3.5 cm. FIG. 4C shows a rubber weight 2c having a weight of 10 grams, a height of 4.5 cm, and a tube 4c covering the weight has a height of 6.0 cm. FIG. 4D shows an iron weight 2d having a weight of 25 grams and a height of 2.4 cm. At this time, the length of the tube 4d covering the weight is 4.5 cm.

  As described above, according to the exercise device of the present invention, the weight of the weight as a load can be appropriately and easily adjusted to appropriately correspond to the skill level of the user of the exercise device and the strength of the shoulder muscles. Can be changed. Thereby, it is possible to train a correct throwing form and muscles such as shoulders in a short time.

  At the end of the manufacturing process, a hole is made in the end of the grip 3 and a loop-shaped strap 6 is provided. If the strap 6 is wound around the wrist, it is possible to prevent the exercise exercise tool from flying away even if the exercise exercise tool slips from the hand when the exercise exercise tool is shaken.

  As described above, according to the method for manufacturing an exercise exercise tool according to the embodiment of the present invention, since the weight 2 is cylindrical, it is easy to fit the weight 2 on the rod-shaped body 1 and heat-treat the heat-shrinkable tube 4. By doing so, the fitted weight 2 can be easily attached to the rod-shaped body 1.

(3) Preferable method of using exercise exercise tool Next, an example of a preferable method of using the exercise exercise tool of the present invention (how to swing) will be described with reference to the weight as a stick. The way of exercising the exercise exercise tool described here is used for baseball pitcher practice, and is based on the so-called current pitching theory developed by the present inventor.

  First, FIG. 5 shows the posture before entering the pitching operation. The practitioner faces the front (home plate side), tightens both sides, widens both legs, holds the glove on the left hand, and naturally grips the grip portion of the exercise equipment A with the right hand (dominant hand). The posture at this time is preferably such that a series of operations described later can be smoothly connected and can respond to a hit ball. In the figure, P indicates a pitching plate.

  Next, as shown in FIG. 6, the knees of the front legs are raised higher than the waist, and the knees of the rear legs are extended. Here, “back foot” refers to the foot on the dominant hand side, and “front foot” refers to the other foot.

  Next, as shown in FIG. 7, the forefoot is landed by lowering the front foot and then stepping on the ground with the rear foot (axial foot). Here, the landing front leg is kept 45 ° inward with respect to the pitching direction, and the distance between the front leg and the rear leg is set to be 3.5 to 4 times the normal stride. Also, at the same time that the forefoot has landed, the dominant hand should be in the highest position (top). At the top, exercise exercise tool A is directed upwards, and the palm of the dominant hand is directed toward the second base (rear side). In addition, the weight put on the back foot after the front foot has landed is put on the front foot and connected to the next movement.

  Next, as shown in FIG. 8, while lowering the center of gravity and swinging down the exercise exercise tool A, tie the forefoot hill (the thickest part of the thumb base) and the back of the knee. The weight is moved to the forefoot while rotating around the axis. After swinging down the exercise equipment, stretch your back leg knee so that your heel is at 90 ° to the ground. Also, after swinging down the exercise equipment, make sure that the elbow of the dominant hand is below the knee of the forefoot so that the shoulder blade of the dominant hand can be seen from the catcher.

  After performing the above operations in conjunction with each other, the posture shown in FIG. 5 is finally taken.

  As a result of the series of operations described above, the muscles of the shoulder are twisted and stretched, so that the inner muscle of the shoulder can be easily trained. Also, in throwing practice using this exercise practice tool, it is not necessary to throw hundreds of baseball balls, so even if the above series of operations are repeated, the shoulder inner muscle is unlikely to wear and shoulder failure is unlikely to occur. .

  Further, when the above-described series of operations can be performed in a correct posture, a sharp sound that cuts off the air is produced. By listening to this sound, the correct swing posture can be easily learned or confirmed. Furthermore, the point where the sound of cutting off the air is the release point of the ball. Therefore, it is possible to practice while being aware of this release point by listening to the sound of cutting the air.

  The above-described method of exercising exercise equipment has been developed for baseball pitcher practice, but can also be applied to baseball fielder practice. In addition, since the way of exercising the exercise equipment has been developed based on the theory that is applicable to many other ball games, it can be applied to such basic exercises of ball games. Furthermore, because the exercise exercise tool is a whole body exercise using not only shoulder muscles but also various other muscles, it is effective in promoting health without presuming ball games.

(4) Exercise exercise tool according to another embodiment FIG. 9 is an exercise exercise tool according to another embodiment, FIG. 9 (a) is a perspective view, and FIG. 9 (b) is a side view thereof. ing. In this embodiment, the weight is a badminton racket net 8. Also in this case, the upper end and the lower end of the net 8 are fixed to the rod-like body 9 by cylindrical heat-shrinkable tubes 7a and 7b, and the grip portion 10 is also fixed by the cylindrical heat-shrinkable tube 7c. When practicing with this form of exercise equipment, the air resistance varies depending on the angle formed by the racket surface and the direction of shaking, but it is fixed by a heat-shrinkable tube. The surface can be prevented from falling off.

  In the above-described embodiment, the case where the weight has a racket shape has been described. However, the present invention is not limited to this. For example, the shape of a bow and arrow or a plate shape may be used.
