Description

[Technical field]

[0001] The present invention relates to a training apparatus and a muscle strength training method. [Background technology]

[0002] A gymnastics device (dumbbell) with metal weights attached to both sides of a metal bar used for muscle training is known (Patent Document 1). A wristband-type muscle training device is also known (Patent Document 2). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Utility Model Application Publication No. 60-094252 [Patent Document 2] Utility Model Registration No. 3099320 Summary of the Invention [Problem to be solved by the invention]

[0004] When the traditional dumbbell described in Patent Document 1 is swung at high speed, centrifugal force acts on the metal weight, making it difficult to control and placing a large strain on the wrist. On the other hand, when the wristband described in Patent Document 2 is used, it is not difficult to control even when the arm is swung, but it is difficult to provide a wristband that is as heavy as a dumbbell and easy to put on and take off.

[0005] SUMMARY OF THE PRESENT EMBODIMENT An object of the present invention is to provide a training device which is sufficiently heavy yet easy to put on and take off, stable to handle, and does not place an excessive strain on the wrists. [Means for solving the problem]

[0006] In order to solve the above problems, the present invention provides a cylindrical training tool that has an internal handle and can be supported not only by the palm but also by the forearm.

[0007] In detail, the present invention is a training device that is held with the forearm and used for the purpose of training each muscle in the upper body of a user, the training device being a thick metal cylinder comprising a cylindrical portion into which the user can insert their hand and forearm from an opening on one side, and a gripping rod that can be held in the palm of the hand inserted into the cylindrical portion and is fixed at two points that are symmetrical with respect to the center of the circle when the cylindrical portion is cut in a cross section along the short side, the gripping rod being located within the cylindrical portion, closer to the opposite side of the opening on one side.

[0008] A user of such a training device can easily use it for muscle training by inserting his / her forearm into the cylindrical part from the opening on one side and holding the gripping bar in the palm of his / her hand. In addition, since the gripping bar is fixed at two points that are symmetrical with respect to the center of the circle when the cylindrical part is cut in the short direction, it is easy to balance when gripping, and the training device does not shake during muscle training, causing unnecessary load on the user's body.

[0009] The gripping bar may be provided at a portion inside the cylindrical portion where the wrist is positioned at the center of gravity of the cylindrical portion when the user grips the cylindrical portion with the palm of his / her hand.

[0010] By making the user's wrist the center of gravity, the torque applied to the wrist when twisting the arm to rotate the training equipment is reduced, so even if such exercise is incorporated into training, the wrist does not exert a large force and it becomes easier to control. For this reason, it is recommended to incorporate rotational movements into strength training. In any case, the user does not need to concentrate on his / her wrist to control the training equipment.

[0011] The cylindrical portion may have an inner diameter of at least 13 cm and at most 17 cm.

[0012] By setting the inner diameter of the cylindrical portion to 13 cm or more and 17 cm or less, the forearm can be easily inserted and removed, and the weight can be supported by the forearm wrapped in the sponge sheet, thereby suppressing shaking of the wrist.

[0013] The cylindrical portion and gripping rod may be made of cast iron and weigh between 5 kg and 20 kg in total.

[0014] By setting the weight of the training equipment to be between 5 kg and 20 kg, it is possible to perform muscle training with an optimal load while maintaining the rigidity of the training equipment.

[0015] The gripping bar may include grooves to aid in gripping.

[0016] This configuration makes it easier to grip the grip bar with the palm of the hand and reduces the likelihood of the grip bar slipping during strength training, improving the stability of the training device.

[0017] A sponge sheet may be provided on the inside of the cylindrical portion at a position where the forearm comes into contact.

[0018] If a sponge sheet is attached to the inside of the cylindrical part on the wrist side, the weight of the training equipment is also applied to the forearm through the sponge sheet, and is not concentrated on the palm, so training can be continued effectively. In addition, there is no need to prepare a separate sponge sheet with the same effect.

[0019] The outside of the cylindrical portion may be covered with an elastic material.

[0020] Even if the training tool comes into contact with another object during use, the elastic force of the elastic member can prevent damage to the other object.

[0021] A training method using this training device may be a muscle training method in which the forearm is inserted into the cylindrical portion of the training device, a gripping bar is grasped with the palm of the hand, the forearm is brought into contact with the inside of the cylindrical portion via a sponge sheet, and the action of moving the forearm is repeated multiple times with periods of rest.

[0022] By using this training device, you can exercise the muscles of your upper body in the same way as when you use existing dumbbells. Furthermore, because the weight of this training device is supported not only by the palm but also by the forearm, it can provide a new stimulus to the muscles you are training compared to when you use existing dumbbells.

[0023] The muscle training method using this training tool may be a muscle training method in which the motion of moving the forearm is quickly repeated.

[0024] This training device supports its weight not only with the fist but also with the forearm, and unlike existing dumbbells, the weight is not unevenly distributed, so it does not wobble even when handled in a manner similar to bodyweight training. This allows for strength training that includes quick movements.

[0025] The muscle training method using this training tool may be a muscle training method in which the movement of the forearm includes a movement of rotating the arm.

[0026] Unlike existing dumbbells, this training device does not have unevenly distributed weight. Therefore, it is easy to maintain stability even when swinging the device. Therefore, it is easy to incorporate rotational movements into strength training.

[0027] The muscle training method using this training tool may be a muscle training method in which the movement of the forearm includes a movement of twisting the arm.

[0028] Because this training device is cylindrical, unlike existing dumbbells, even if the arm is rotated like a screw, the force is not concentrated in a specific direction and is easy to control. In addition, because the user's wrist is the center of gravity of this training device, the rotation does not put much force on the user's wrist. Therefore, the arm twisting action can be easily incorporated into muscle training. Effect of the Invention

[0029] When a user puts their arm through the training device of the present invention and grasps the internal handle, the weight is distributed to the forearm as well as the palm, and even when swinging it around, excessive strain is not placed on the wrist, allowing the user to stably perform the same exercises as with existing dumbbells and easily perform strength training that incorporates movements that are difficult to perform with existing dumbbells.

[0031] Hereinafter, a training device according to an embodiment of the present invention and a training method using the training device will be described with reference to the drawings. Note that the configurations of the following embodiments are merely examples, and the present invention is not limited to the configurations of these embodiments.

[0032] <Embodiment> FIG. 1 is a perspective view of the appearance of a training device according to an embodiment. The training device 1 is a training device used mainly for the purpose of training the muscles of the upper body of a user. is a thick and heavy cylinder made of metal, more specifically cast iron. The cylinder 2 plays the role of a weight in an existing dumbbell. There is a gripping bar 3 that crosses the cylinder 2, biased to one side in the longitudinal direction inside the cylinder 2. The gripping bar 3 is a rod-shaped structure that can be held by the palm of the user, and in this embodiment, it is fixed to the cylinder 2 by welding. On the side without the gripping bar 3, there is a one-side opening 5 into which the hand and forearm can be inserted. The user can insert his or her hand and forearm into the one-side opening 5 and firmly grip the gripping bar 3 with the palm to perform various muscle training. In the present application, in the longitudinal direction of the cylinder 2, the side where the one-side opening 5 exists is the insertion opening side, and the side where the gripping bar 3 exists, which is closer to the opposite side of the one-side opening 5, is the gripping bar side.

[0033] FIG. 2 is a cross-sectional view of the training device according to the embodiment. The cylindrical portion 2 is a cylinder through which the forearm can pass, and the gripping bar 3 is fixed by welding at two points on the upper portion of the cylindrical portion 2 (the side opposite to the side where the arm enters, the gripping bar side), which are symmetrical points with respect to the center of the circle when the cylinder is cut in the short direction. The gripping bar 3 may have a groove engraved thereon to assist gripping, which makes it easier to grip. In addition, a grip tube made of an elastic material may be attached. The thickness of the cylindrical portion 2 is uniform around the circumference, and when the forearm is inserted from the side of the opening 5 on one side and the center of the gripping bar 3 is supported and lifted, the opening 5 on one side faces vertically and comes to rest. Due to this feature, in this training device, it is easy for the user to grip the gripping bar 3 and maintain balance.

[0034] The inner diameter of the cylindrical portion 2 is, for example, 15 cm. The inner diameter of the cylindrical portion 2 is preferably 13 cm to 17 cm. If the inner diameter of the cylindrical portion 2 is 13 cm or more, the user can easily insert the forearm into the one-side opening 5 of the training tool 1. If the inner diameter of the cylindrical portion 2 is 17 cm or less, even if the user swings the training tool around, the weight is distributed to the forearm via the sponge sheet described below, so that excessively strong force is not applied to the wrist. The weight of the training tool 1 is the sum of the weight of the cylindrical portion 2 and the weight of the gripping rod 3, and is, for example, 10 kg. The weight of the training tool 1 can be changed by changing the thickness or length of the cylindrical portion 2. Depending on the muscle strength of the user and the type of muscle fiber to be trained, the training tool 1 can be provided with various weights, for example, in the range of 5 kg to 20 kg. In addition, holes or recesses can be made on the surface side of the cylindrical portion 2 to improve aesthetics. The length of the cylindrical portion 2 is, for example, 25 cm, and at this length, a user wearing the training device 1 can easily bend his / her elbow and also support his / her weight on the side of his / her forearm. The length of the cylindrical portion 2 can be changed depending on the weight of the training device 1.

[0035] FIG. 3 is a schematic diagram showing a state in which a forearm is inserted into the training tool according to the embodiment and a gripping bar is gripped. The user inserts the forearm 12 into the training tool 1 and grips the gripping bar 3 inside with the palm 10. The gripping bar 3 is provided at a location where the center of gravity of the training tool 1 including the forearm is near the wrist 11 of the user when the user grips the center of the gripping bar 3 with the palm. Even if the user rotates the training tool 1 by twisting the forearm in this state, the torque associated with the rotation is unlikely to be applied to the wrist 11 of the user. Therefore, even if the user rotates the training tool 1 by twisting the arm, the user can easily continue to grip the gripping bar 3, and can perform muscle training including rotational movement without putting a load on the wrist.

[0036] FIG. 4 is a diagram showing a method of inserting and fixing a forearm into a training device according to an embodiment. The user wraps a sponge sheet 4 around the forearm, inserts the hand and forearm through an opening 5 on one side of the training device 1, and grasps the gripping bar 3. As described above, the gripping bar 3 is provided at a position that makes it easy to balance the center of gravity. Furthermore, since the forearm 12 contacts the cylindrical portion 2 via the sponge sheet 4, the weight of the training device 1 is distributed not only to the hand but also to the forearm, and the user can hold the training device 1 with not only the hand but also the forearm. For this reason, the user can easily hold the training device 1 with the forearm. The user can perform the necessary training with the feeling that the tool 1 and the forearm 12 are integrated.

[0037] The sponge sheet 4 is a thick sponge-like sheet made of polyester, polyurethane, etc., and is wrapped around the forearm when the training device 1 is worn. The sponge sheet 4 can be used in layers to provide an optimal fit depending on the thickness of the user's forearm. The number of sponge sheets 4 may be increased or decreased depending on the intensity of the exercise. These adjustments may be made by replacing sponge sheets 4 with different thicknesses.

[0038] The material of the cylindrical part 2 and the gripping rod 3 is not necessarily limited to cast iron. The cylindrical part 2 and the gripping rod 3 may be made of a metal or alloy that has sufficient rigidity and strength as a training tool and a specific gravity that is heavy enough for muscle training, and it is possible to select one that is suitable for muscle training.

[0039] The outside of the cylindrical portion 2 may be coated with an elastic material such as rubber. The training device 1 according to the embodiment is highly stable when worn compared to its weight and can be quickly handled, so that it may come into contact with other objects at high speeds. If the training device 1 is covered with an elastic material, even if the training device 1 comes into contact with another object during use, damage to the other object can be prevented. In addition, noise is less likely to be generated when the training device 1 is placed on the floor.

[0040] Furthermore, the sponge sheet 4 may be attached in advance to the position on the inside of the cylindrical portion 2 that contacts the forearm, rather than being wrapped around the forearm during training. In this way, when the user uses the training tool 1 for strength training, there is no need to prepare a separate sponge sheet 4.

[0041] <Effects of the Invention> In existing dumbbells, weights are attached to both sides of the bar, so strong centrifugal force is generated when the arm is rotated, but in the training device 1 according to the embodiment, the weight is in the cylindrical part 2, so there is no wobble even when rotated and stability is maintained. Also, because the weight of the device is supported not only by the palm but also by the forearm, the load is not concentrated on the wrist, and muscle training (training) including quick movements can be performed in a manner similar to bodyweight training.

[0042] In the field of strength training, a mechanism called the "principle of awareness" (mind-muscle connection) has been researched and reported. This principle states that focusing one's attention on the muscle being trained increases muscle activity and improves the training effect. In the training device 1 according to the embodiment, the center of gravity is at the wrist, so that even when performing complex exercises, the wrist is not easily burdened, and the weight can be received by the forearm through the sponge sheet 4. Therefore, the user does not need to distribute his / her attention to control the training device 1 during strength training. Therefore, the user can focus his / her attention on the target muscle, and the training effect can be improved by the principle of awareness.

[0043] <Application of existing training methods> Using the training device 1 according to the embodiment, muscle training can be performed by applying the movements performed with existing dumbbells. A specific example of an existing muscle training method using the training device 1 according to the embodiment is shown below. In the following training performed with existing dumbbells, it can be difficult to control heavy dumbbells when they are moved at high speed, so it is common to move the arm slowly with relatively simple movements. The training device 1 according to the embodiment is easy to control, and movements including quick movements can be incorporated into muscle training. In addition, since the weight of the training device 1 is supported not only by the palm but also by the forearm, a new load different from that of existing dumbbells can be applied to the target muscles. In addition, In addition, the use of the training device 1 makes it easy to incorporate the movement of rotating the forearm in a screw-like manner, which allows a new load to be applied to the target muscle, thereby improving the training effect.

[0044] <Training Method 1> Fig. 5 is a diagram showing a first training method. Fig. 5 shows a training method called side raise. A user wearing the training tool 1 according to the embodiment on both arms slowly repeats a posture of standing with arms lowered at shoulder width and a posture of stretching both arms out to the side (approximately parallel to the floor) multiple times, stopping at the end. This method can train the shoulder muscles, mainly the deltoids.

[0045] <Training Method 2> FIG. 6 is a diagram showing a second training method. FIG. 6 shows a twisting type exercise. A user wearing the training tool 1 according to the embodiment on both arms slowly repeats a posture of leaning forward with arms lowered and facing each other, and a posture of raising the arms with elbows turned outward, stopping at the end, multiple times. This method can train the posterior deltoids and upper back. This training may be a training method in which both arms are raised at the same time with the upper body tilted forward (rear raise). This training movement may also include a movement of twisting the arms.

[0046] <Training Method 3> Fig. 7 is a diagram showing a third training method. Fig. 7 shows a training method called bent-over row. A user wearing the training device 1 according to the embodiment on both arms slowly repeats a posture of pushing the hips back, sticking out the chest, lowering the hands, and bending the arms while raising the hands to the sides of the chest, stopping at the end. This method can train the back muscles, mainly the latissimus dorsi.

[0047] <Training Method 4> FIG. 8 is a diagram showing a fourth training method. FIG. 8 shows a training method called curl. A user wearing the training device 1 according to the embodiment on both arms slowly repeats a posture of standing with feet shoulder-width apart and back straight, and a posture of bending elbows and raising fists in front of shoulders, stopping at the end. One arm or both arms may be exercised at the same time. This method can train the upper arm muscles, mainly the biceps.

[0048] <Training Method 5> FIG. 9 is a diagram showing a fifth training method. FIG. 9 shows a training method called pullover. A user wearing the training device 1 according to the embodiment on both arms lies on his / her back on a work bench, and slowly repeats a posture of sticking out his / her arms above his / her chest and a posture of sticking out his / her arms to the top of his / her head, which is an extension of the midline, several times, stopping at the end. One arm or both arms may be exercised at the same time. This method can train the latissimus dorsi and pectoralis major muscles.

[0049] <Training Method 6> FIG. 10 is a diagram showing a sixth training method. FIG. 10 shows a training method called fly. A user wearing the training device 1 according to the embodiment on both arms lies on his / her back on a work bench, and slowly repeats a posture in which both arms are thrust out over the chest and a posture in which both arms are spread out to the sides (approximately parallel to the floor) several times, stopping at the end. Either one arm or both arms may be exercised at the same time. This method allows the muscles of the chest, mainly the pectoral muscles, to be trained.

[0050] <Training Method 7> FIG. 11 is a diagram showing a seventh training method. FIG. 11 shows a training method called French press. A user wearing the training tool 1 according to the embodiment on both arms slowly repeats a posture of raising one arm above the head and a posture of bending the elbow and lowering the forearm behind the head several times, stopping at the end. This method can train muscles, mainly the triceps.

[0051] <Training Method 8> FIG. 12 is a diagram showing an eighth training method. FIG. 12 shows a training method called kickback. A user wearing the training tool 1 according to the embodiment slowly repeats a posture in which the user leans forward with the elbow bent at a right angle and the forearm facing the floor surface, and a posture in which the forearm is thrust out behind the body without changing the position of the elbow, stopping at the end point. This method can also be performed in a posture in which one knee and one arm not wearing the training tool 1 are placed on a training bench. This method can train the triceps.

[0052] <Training Method 9> FIG. 13 is a diagram showing a ninth training method. FIG. 13 shows a training method called lying extension (lying triceps extension). A user wearing the training tool 1 according to the embodiment lies on his / her back on a training bench, and slowly repeats a posture in which the arms are stretched above the chest and a posture in which the arms are bent so that the forearms are diagonally above the head, stopping at the end of the posture. This method can train the triceps.

[0053] <New training method> It is difficult to use existing dumbbells to train with quick rotational movements or quick linear movements because the weight is subjected to strong centrifugal force, causing the wrist to shake. However, in the training device 1 according to the embodiment, the part corresponding to the weight is the cylindrical part 2, and the weight can also be supported by the forearm, so that it is less likely to shake even when centrifugal force is applied. Therefore, the user can train in a manner similar to bodyweight training using the training device 1 according to the embodiment, and can concentrate more on the target muscle. In addition to the muscle training that applies the existing dumbbell exercise described above, the training device 1 according to the embodiment can also perform the following new muscle training.

[0054] <Training Method 10> 14 is a diagram showing a tenth training method newly enabled by the training device according to the embodiment. A user wearing the training device 1 according to the embodiment on both arms spreads his / her sides, stretches his / her forearms forward, and repeats the motion of quickly rotating them on the spot. Alternatively, the user may hold both forearms parallel to the chest and parallel to the ground, and rotate both arms alternately in front of the chest.

[0055] <Training Method 11> 15 is a diagram showing an eleventh training method newly enabled by the training device according to the embodiment. A user wearing the training device according to the embodiment on both arms stands with arms lowered and shoulder-width apart, then raises one arm to shoulder level and repeats a motion of quickly swinging it behind the body (a motion similar to a back fist in karate).

[0056] <Training Method 12> 16 is a diagram showing a twelfth training method newly enabled by the training device according to the embodiment. A user wearing the training device 1 according to the embodiment on both arms Stand with shoulder width apart, put one foot forward, raise your fist (equipped with training device 1) in front of your chest, and repeat short punches like a rush in a boxing match. These new training methods can improve the coordination of the shoulders and arms, including the inner muscles.

[0057] The novel training method is not limited to the above, and for example, the user can wear the training device 1, stand with shoulder width apart, and move both arms as if swimming the crawl or breaststroke. These movements can mainly train the rotator cuff.

[0058] The features of the training device according to the embodiment and the muscle training method using the training device have been described above, but the contents of the present invention can be further developed as follows. For example, the training device 1 can be made of hollow metal or resin, a connecting hole to the outside can be provided in a part of it, and a removable cap can be provided on the connecting hole. When the user is training, he or she can open the cap and fill the inside with liquid or sand, and the training device 1 can be used easily and with high stability. When training is not being performed, the liquid or sand filled inside can be discharged, making it easy to handle when stored. Training device 1 of this type is easy to use, especially when training at home.

[0059] The embodiments and training methods disclosed above can be combined with each other. [Explanation of symbols]
