Description

  The present invention relates to a training tool and a training bat that can efficiently enhance gripping force in training (including preparatory exercises) of swinging with a grip portion.

  In order to strengthen grip strength by sports or rehabilitation (including restoring weak grip strength or preventing decline in grip strength), muscles that flex and extend wrists and flex and extend fingers I need to train my muscles.

  A method called “hand grip” is well known as a training method for training finger muscles. The “hand grip” uses a device called a “hand clipper” of a nut cracker type (walnut split type) in which two grip portions are disposed at both ends of a torsion coil spring (torsion spring). A finger is put on a grip part of a book and gripped so that the two grip parts are brought close to each other against a load of a spring (crushing), thereby forging a muscle that bends the finger.

  Also, in baseball and softball training, training bats (mascot bats) with a structure that puts a greater load on the user's body than bats used in games are used to practice swinging or head to the main bat A preparatory exercise is carried out, and a conventional training bat is used which is adjusted to be heavier than the bat used in the game. As a bat whose weight can be adjusted, a bat whose weight can be adjusted by providing a desired weight at the grip end has been developed (see Patent Documents 1 and 2).

  The training device 1 of the present embodiment is a portable training device 1 that includes a grip portion 2 that is used with a strong grip with a palm, and is used for practice of swinging and for the purpose of strengthening gripping power. While performing with the training tool 1 having the same diameter as the grip part 2 of the tool actually used in a game or the like, the grip strength can be effectively enhanced.

  As shown in FIGS. 1 to 3, the grip portion 2 of the training tool 1 is made of a hard material such as wood, metal, or carbon formed to have a diameter smaller than a desired diameter of the grip portion 2. The shaft portion 3 is provided. The shaft portion 3 may be the entire shaft or a part of the shaft of the training device 1, and may be a hollow structure or a solid structure.

  An elastic deformation member 4 that can be elastically deformed by gripping from the outer peripheral side is fixed to the outer periphery of the shaft portion 3 with an adhesive (not shown).

  The elastic deformation member of the grip portion of the training device shown in FIGS. 1 and 2 of the present embodiment is formed into a bottomed or bottomless cylindrical shape with an elastic material having a thickness of about 5 mm to 20 mm. In general, the grip portion 2 is formed with an appropriate elasticity so that the grip portion 2 can be elastically contracted to the desired diameter by gripping with a gripping force to which a load intended for reinforcement training is applied. In other words, when the desired diameter dimension of the grip part 2 is X, the diameter dimension of the shaft part 3 is X-α, and the outer diameter dimension of the grip part 2 when not in use is X + β (FIGS. 1 to 3). 3), the elastic deformation member 4 adjusts the elasticity and the like so that the grip portion 2 having a diameter size of X + β can be elastically contracted to the desired diameter size X by the gripping force for the purpose of strengthening the gripping force. Is formed.

  Examples of the hard elastic material include a resin foam made of polyvinyl chloride, urethane, rubber (natural / synthetic), silicon, polyethylene, polypropylene, and the like, and a material obtained by mixing a filler or a curing agent with silicon (resin). May be appropriately selected and used according to the target load of the grip strength training.

  The elastic deformation member 4 may be formed in a plurality of layers by overlapping hard elastic materials of different materials. Moreover, you may coat | cover the outer surface of the said hard elastic material with the coating film provided with the elasticity which tracks the shape change. For coating film formation, for example, urethane-based or polyvinyl chloride-based paints can be used.

  In addition, the elastic deformation member 4 is also formed between an outer periphery of the shaft portion 3 and an inner surface layer 5a to be fixed and an outer surface layer 5b constituting the outer periphery of the grip portion 2, as shown in FIG. Resin and foam particles such as silicon bouncing putty, plastic foam, air mat, gel, etc. that have elasticity in the enclosed space, or the so-called shock absorbing material gel that absorbs shock and takes grip strength The intermediate layer 6 may be formed. That is, if the elastic deformation member 4 constituting the grip portion 2 has a repulsive force, the gripping force can be strengthened by resisting the repelling force, while if the shock is absorbed, the finger muscles can be further increased. Because it will overuse, it will be training to strengthen the grip. The intermediate layer 6 may be formed in a plurality of layers, or a wall portion that partitions the space in the circumferential direction of the shaft portion 3. The inner surface layer 5a and the outer surface layer 5b may be formed thinly by injection molding using the same material using a hard polyurethane resin, hard rubber, or the like.

  In the swing training using the training device 1 of the present invention, the gripping part 2 is gripped by gripping the elastic deformable member 4 with a gripping force that is applied to the purpose of gripping strength strengthening training against the elastic force during the swinging exercise. The body is elastically shrunk to the radial dimension, and the swinging practice is performed with the grip part 2 as a desired radial dimension in the same grip state as the actual production.

  At that time, by gripping the grip part 2 with a gripping force that is applied for the purpose of strengthening the grip strength training, the grip part 2 of the conventional training device that does not have the configuration as in the present invention is compared with the case where the grip part 2 is strongly gripped. , You can also efficiently strengthen the strength of your fingers and strengthen the grip.

  While the elastic deformation member 4 is gripped at a gripping force less than the target load for gripping strength strengthening training, the grip portion 2 does not have the same desired diameter size as that of the actual tool, but there is a hindrance to swinging practice. In addition, the training for strengthening the grip strength will be done so that the same grip state as the actual one can be obtained. On the contrary, if the elastic deformation member 4 is gripped with a gripping force higher than the target load for gripping strength training, the grip portion 2 will be less than the desired diameter, but there will be no problem in the practice of swinging. By continuing to grip against the elasticity of the elastic deformation member 4, so-called isometric training is achieved, and the muscle strength of the fingers can be trained and the grip strength can be enhanced.

[Bat for training]
In the following, a swing training bat (training bat) 11 such as baseball or softball, which is an example of the training tool 1 described above, will be described.
