Description

Forearm Strengthening Training Sword {FOREARM MUSCLE TRAINING SWORD}

The present invention relates to a forearm reinforcement training dagger, more specifically, to facilitate the distinction between a dagger and a dagger, as well as a weight, weight change and length adjustment similar to that of a dagger, it is possible to feel an effect such as a real sword or axe. It is related to the forearm for strengthening forearm training.

In general, practitioners who require forearm muscle strengthening include kendo, baseball, boxing, tennis, golf and martial arts. In order to strengthen the forearm muscles, wrist curls, hammer curls, winding machines, and green machines (pressors) have been used in the past, but these training equipments have a low forearm exercise effect.

In particular, in Kumdo, Kumdo training is used to train and cultivate the mind and body by practicing basic movements using wooden swords such as wooden swords or bamboo swords and bamboo swords such as Dalian, and swordsmanship using swordsmanship. have. Among them, the practice of swordsmanship using the swordsman is performed by high-ranking martial arts masters who are excellent in martial arts by practicing swordsmanship for a long period of time, to practice more sophisticated movements. Because there is a risk of causing fatal injury to the other person or the city, for safety reasons, the use of a false sword should be used to practice posture correction and other methods of skill polishing.

The training of ordinary subordinates is practiced using the wooden sword or bamboo sword mentioned above, such as stabbing or cutting, but in the case of bamboo sword, most of the movements by the blow using the wrist mainly dominate in Korea Since the movement is unnatural to practice movements such as stabbing or cutting, which are the basic movements of traditional swordsmanship, there are difficulties in effectively mastering the basic movements or skills, and the above problems are encountered in the process of fighting against each other to form a sword. There is a weighting disadvantage.

However, although the conventional dagger for training has a blunt blade, it has the same appearance and weight as a dagger, and it has been pointed out that it can be used for threats or crimes against opponents.

In addition, the conventional training sword has a disadvantage in that the coupling structure is complicated and the separation between the constituent members frequently occurs as a separate fixing device for fixing a heavy object inserted into the body of the knife should be provided. .

On the other hand, the above-mentioned background technology is the technical information acquired by the inventor for the derivation of the present invention or acquired in the derivation process of the present invention, and is not necessarily a known technology disclosed to the general public before filing the present invention. .

Here, the weight distribution is preferably such that the weight of the blade tip 110 is concentrated to 70% or more. In other words, the total weight of the sword can be produced at intervals of 250g up to 3kg or more, starting from 500g, but may be produced differently depending on the purpose of the user's exercise.

The knife 100 having the above-described configuration can freely adjust the length of the sword by adjusting the number of the conductive parts 120 according to the user's needs, and also the number of weights 300 entering the sword. You can freely adjust the amount of exercise to maximize the effect of your forearm muscle exercise.

FIG. 4 is a view showing another embodiment of the conductor of FIG. 2.

Referring to FIG. 4, the conductive part 120 according to another embodiment includes a body 123, a hollow 124, and a vibration part 500.

The body 123 is fastened to the rear end of the blade end 110, a hollow 124 is formed inside, a fastening groove 122 is formed at the front end, and a fastening protrusion 121 is provided at the rear end.

The hollow 124 is formed inside the body 123, and the vibration part 500 is installed in the interior space.

The vibration unit 500 is installed in the hollow 124 so as to assist the user's forearm strengthening training, and vibrates in the front-rear direction in the hollow 124 as the user swings the sword.

The conductor 120 according to another embodiment having the above-described configuration vibrates in the inner space of the hollow 124 according to the user's movement instead of the weight to add weight to the inner space of the hollow 124 By adding a vibrating unit 500 capable of wielding the sword and supporting the sword, the sword reciprocates the inner space of the hollow 124 as shown in (a), (b) and (c) of FIG. 5. It is possible to induce a more efficient forearm exercise by providing exercise according to overcoming resistance due to vibration of the east 500.

Referring to FIG. 4, the vibration unit 500 may include a vibration weight 510, two first elastic ropes 520 and two second elastic ropes 530.

The vibrating weight 510 is made of an object having a large specific gravity, such as a metal bundle, and is disposed in the air of the hollow 124 by the first elastic rope 520 and the second elastic rope 530, and the user swings a sword It vibrates in the front-rear direction in the hollow 124 by the inertia according to. Here, in order to reduce or remove noise caused by vibration of the vibration weight 510, a sound absorbing material and a noise inhibitor may be attached to the hollow wall surface.

The first elastic rope 520, one end is installed on the front end surface of the hollow 124 so as to pull the vibration weight 510 in the shear direction of the hollow 124 by using an elastic force, the vibration weight 510 of Returning to the front end surface of the hollow 124 via one side or the other side, the other end is installed on the front end surface of the hollow 124.

The second elastic rope 530, one end is installed on the rear end surface of the hollow 124 to pull the vibration weight 510 in the rear end direction of the hollow 124 by using an elastic force, the vibration weight 510 of Returning to the rear end face of the hollow 124 via one side or the other side, the other end is installed on the rear end face of the hollow 124.

In one embodiment, the vibrating weight 510 is moved to the shear direction of the hollow 124 by the inertia when the user wields the dagger (FIG. 5 (b)), and the elastic force of the second elastic rope 530 While moving in the direction of the rear end of the hollow 124 (Fig. 5 (c)) and by moving the elastic force of the first elastic rope 520 in the shear direction of the hollow 124 (Fig. 5 (b)) repeatedly The hollow 124 may perform vibrational motion.

6 and 7, the body 123 is hollow (124) from the front end and the rear end so that one end or the other end of the first elastic rope 520 or the second elastic rope 530 passes through and is exposed to the outside. ) May be formed through two through holes 1231 formed at the front end and two at the rear end.

In one embodiment, the first elastic rope 520 or the second elastic rope 530, one or the other end is exposed to the outside through the through-hole 1231, the penetration formed in the front end or rear end of the body 123 One end or the other end may be fastened to the fastener 1232 fastened to the entrance of the hole 1231.

In one embodiment, the first elastic rope 520 or the second elastic rope 530, the elastic force pulling the vibrating weight 510 increases as the one or the other end is pulled through the through hole 1231 You can.

In one embodiment, the vibration weight 510, as the elastic force of the first elastic rope 520 or the second elastic rope 530 decreases, the amplitude in the hollow 124 increases, the first elastic rope 520 ) Or as the elastic force of the second elastic rope 530 increases, the amplitude in the hollow 124 may be reduced.

That is, when the amplitude of the vibration weight 510 is increased, the amount of exercise transmitted to the user's forearm increases, thereby increasing the exercise effect. When the amplitude of the vibration weight 510 decreases, the amount of exercise delivered to the user's forearm muscle is increased. As the number of exercise effects decreases, the user can maximize the exercise effect according to the purpose by adjusting the length of the first elastic rope 520 or the second elastic rope 530 according to his or her exercise purpose.

The above-described embodiments are for illustration only, and those skilled in the art to which the above-described embodiments belong can easily be modified into other specific forms without changing the technical idea or essential characteristics of the above-described embodiments. You will understand. Therefore, it should be understood that the above-described embodiments are illustrative in all respects and not restrictive.
