Description

  The present invention relates to a health device.

  Conventionally, dumbbells are widely known as training devices that can be used at home. The dumbbell is used, for example, for the purpose of training muscles such as shoulders and arms by performing repetitive movements such as a user holding it with one hand and moving it up and down. Furthermore, in recent years, with the increase in health consciousness, dumbbells are used for exercises aimed at slimming and health maintenance in addition to the above-mentioned training aimed at strengthening muscle strength, regardless of age or gender. It has been used for a wide range of people.

  However, the above-mentioned dumbbell is merely a device that trains muscles by performing monotonous repetitive movements against gravity, and a comprehensive health promotion effect including improvement of motor function and cranial nerve function cannot be expected.

  Also, dumbbells are generally composed entirely of metal such as iron, and are hard and relatively heavy, so that they are difficult to handle for persons with reduced physical strength such as sick and elderly people. On the other hand, in order to obtain results from training, it is necessary to perform exercise with a higher load than the level of daily physical activity (overload principle). There was a problem that could not be obtained.

  Therefore, one of the problems to be solved by the present invention is to provide a health device that can obtain a comprehensive health promotion effect including recovery and improvement of not only physical strength and muscle strength but also motor function and cranial nerve function. It is. Another problem to be solved by the present invention is to provide a health device that can be used safely and easily and that can obtain a high exercise effect.

  The health device according to the present invention, which has been made to solve the above-mentioned problems, is a health device that can be used for both weight training and gripping exercise, and is made of a rod-shaped core material made of a hard material and having an elastic thickness of 10 mm or more. It is characterized by having a total weight of 100 to 500 g.

  Here, the core material functions as a support for maintaining the overall shape, and also serves as a weight that gives an appropriate weight to the entire health device. According to the health device having the above-described configuration, weight training similar to that of the dumbbell can be performed by gripping the health device and moving it against gravity, and the health device can be applied to the elastic force of the resin foam. A gripping motion (grip motion) can be performed by gripping and loosening against it.

  Conventionally, in the motor area of the brain that controls the movement of each part of the body and the somatosensory area that receives the sensation from each part of the body, it has been known that there is a correspondence between each part of the body and the brain region. And the finger area has been found to occupy a large area. Furthermore, nerve cells are known to increase neurites and increase the number of synapses when stimulated, and it is effective to activate the brain to move and stimulate the fingers, Generally known widely. Therefore, according to the present invention, it is possible to excite the somatosensory cortex by stimulating the palms and finger pads while simultaneously activating the motor cortex that controls the movement of the fingers by performing the gripping motion as described above. Therefore, not only the muscular strength enhancement effect by weight training but also the maintenance or improvement effect of motor function and cranial nerve function can be expected.

  Furthermore, weight training can also be performed in a state where the muscles of the upper limbs, the back and the chest are moderately tensioned by gripping the health device of the present invention strongly against the elastic force of the resin foam. As a result, the exercise effect of the training can be increased, and sufficient results can be obtained even with such a lightweight weight. At this time, the user himself / herself adjusts the force for grasping the health equipment, so that the exercise intensity can be increased without difficulty according to the individual physical strength.

  In addition, according to the health device of the present invention, in addition to the muscle strength enhancing effect of the upper limbs, the back, or the chest by weight training, it is possible to obtain the grip strength enhancing effect by the gripping exercise.

  Furthermore, the health device of the present invention is lightweight, and the resin foam that covers the core surface thickly absorbs the shock at the time of dropping or collision, so there is no risk of injury even if it is dropped. Even those with reduced grip strength, such as the elderly and sick, can be used easily.

  The health device according to the present invention can also have a shape obtained by curving the core material in an arc shape.

  In such a configuration, it is possible to enhance the fit to the hand by gripping the curve so as to follow the depression of the palm, and the stimulation of each part of the finger received by appropriately rotating the health device. The intensity can be changed variously, and the brain can be activated more effectively.

  As described above, according to the health device of the present invention having the above-described configuration, it is possible to obtain a comprehensive health promotion effect including not only enhancement of muscle strength but also recovery and improvement of motor function and cranial nerve function. Moreover, the health device of the present invention can be used safely and easily, and at the same time, it is possible to increase the exercise intensity without difficulty according to the user's intention.

  In the health device of the present invention, the core material may be any material as long as it is made of a hard material and has an appropriate weight. For example, iron, copper generally used for dumbbell weights, etc. It is desirable to be made of a metal such as lead. The weight of the core material is appropriately set so that the total weight of the health device including the resin foam is in the range of 100 to 500 g, preferably in the range of 150 to 350 g. In addition, any resin foam having elasticity may be used, but in order to obtain elasticity suitable for the gripping motion, the expansion ratio is 10 to 40 times, more preferably 15 to 25 times. It is desirable to use a foam made of polyvinyl chloride, urethane, polypropylene, polyethylene, rubber, or silicon. The thickness of the resin foam is preferably 10 mm or more, and the thickness of the resin foam at least at a portion gripped by the user is preferably 20 mm or less. If it is thinner than 10 mm, sufficient elasticity cannot be obtained, and if it is thicker than 20 mm, the flexibility becomes too high, and it becomes difficult to perform a gripping movement that resists elastic force.

  Furthermore, in order to prevent dirt from adhering to the resin foam, it is desirable to form a stretchable coating film on the surface of the resin foam. By imparting elasticity to the coating film, the coating film can follow the deformation of the resin foam, and the coating film can be prevented from cracking or peeling. Such a coating film can be formed, for example, by applying a urethane-based paint or a polyvinyl chloride-based paint having elasticity to the surface of the resin foam.

  The size of the health device according to the present invention is not particularly limited, but it is desirable that the overall length is in the range of 120 to 200 mm so that it can be easily handled with one hand. In addition, it is desirable that the diameter of the portion gripped by the user is in the range of 40 to 50 mm so that the gripping movement can be easily performed. Further, when the core material is curved in an arc shape as described above, it is desirable that the radius of curvature of the central axis of the core material is in the range of 350 to 450 mm. If it exceeds this range, the effect of providing a curve cannot be obtained sufficiently, and if it falls below this range, it becomes difficult to grip and the feeling of use may be reduced.

  The health device according to the present invention may be manufactured by any method. For example, it is manufactured by adhering a sheet material made of an elastic resin foam to the peripheral surface and both end surfaces of the core material. It is desirable to make it. With such a configuration, it is possible to manufacture easily and at low cost without using a special device.
