Description

  The present invention relates to an underwater exercise assisting device that assists a user's exercise by imparting buoyancy during underwater exercise such as swimming and aquabics.

  FIG. 7 is a diagram showing a human body, FIG. 8 is a diagram showing a state of floating in water, (a) is a diagram showing a balanced state in water, and (b) is a balanced state in water. FIG. Since a person who is good at swimming has a good position of the center of gravity of the body in water, the line from the thymus to Tanda is almost horizontal as shown in FIG. On the other hand, a person who cannot swim, such as a beginner swimming, has a poor balance because the bottom of the sunk sinks as shown in FIG. In addition, since a person with a physical disability has weak muscle strength in an inconvenient part, the part sinks, and the position of the center of gravity of the body shifts and balance is lost. Further, even a person who can swim to some extent can get better time by correcting the position of the center of gravity. Thus, the position of the center of gravity of the body in the water is important in swimming.

  In addition, there are aquabics that walk underwater and do fitness exercises for physical rehabilitation, strengthening, beauty, health and the like. Since buoyancy acts in the water, the burden on the body due to gravity is less likely to be applied to the waist and legs, and it is possible to exercise with a large momentum with the resistance of water and water pressure as loads. During such aquabics, it is preferable to exercise with the body leaning forward to resist the resistance of water. However, particularly elderly people with low muscular strength lose their resistance to water and their bodies warp backwards, causing the balance in water to be lost. Therefore, on the contrary, there is a possibility that the waist is burdened and hurt.

  Therefore, Patent Document 1 is characterized in that in a swimming garment such as a swimsuit or a swimming pants made of cloth or a synthetic resin film, a means for increasing buoyancy is provided to assist body buoyancy in water. A swim garment is disclosed.

JP-A-9-195108

  However, the swimming garment described in Patent Document 1 cannot be removed because the buoyancy member is sewn. Therefore, although the required buoyancy varies depending on the wearer's level, the buoyancy cannot be adjusted because the buoyancy member is integrated with the swimming garment. Moreover, it is only necessary to give buoyancy to only a handicapped part of a person with a physical disability, but with the swimming garment described in Patent Document 1, the position of the buoyancy member cannot be changed.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide an underwater exercise assisting device that can provide buoyancy according to the level of a user and a necessary location.

  In order to achieve the above object, the present invention is a plate-like body provided with an elastic foam layer having a closed cell structure having buoyancy, and is characterized by being used by being detachably attached to the inner surface side of a swimsuit. This is an underwater exercise aid. The user can be given buoyancy by the elastic foam layer having buoyancy. In addition, because it is detachably attached to the inner surface of the swimsuit by sandwiching it between the swimsuit and the skin without sewing to the swimsuit, the buoyancy can be adjusted by increasing or decreasing the number of auxiliary tools used, It is possible to change a place where buoyancy is applied by changing a place where the auxiliary tool is put. The term “swimwear” in the present application is a concept that includes not only clothing worn during swimming such as swimming, but also general clothing worn in water such as wet suits and dry suits. The “inner side of the swimsuit” may be between the outer surface of the swimsuit and the skin, and other materials may be interposed therebetween.

As a magnitude | size of the auxiliary tool for underwater exercise, it is good to make the area of a plate-shaped body plane into 100-200 cm < ² >. If it is larger than this range, it will be difficult to attach / detach to / from the inner surface of the swimsuit, and it will be easy to overlap each other when worn, resulting in increased thickness of the overlapped part, which may impede exercise, and will have a rough appearance. Is conspicuously undesirable. Moreover, if it is smaller than the said range, there is no sense of stability inside a swimsuit and a position tends to shift | deviate and it is unpreferable. Further, in order to obtain buoyancy, it is necessary to increase the number of plate-like bodies, which takes time for loading and unloading, and there is a risk of hindering the movement of the body.

  The thickness of the plate-like body is 0.5 to 1.5 cm, preferably about 1 cm. If it is larger than this range, the thickness will increase when placed on the inner surface side of the swimsuit, the water will be resisted, there is a risk that smooth movement will be hindered, and the appearance will be conspicuous. Moreover, if it is smaller than the said range, the thickness of the elastic foam layer which has a buoyancy will become thin, and sufficient buoyancy cannot be given to a body.

  The specific gravity of the plate-like body with respect to water is preferably 0.01 to 0.1. If the specific gravity is greater than 0.1, the buoyancy imparted to the human body is insufficient. Moreover, if the specific gravity is smaller than 0.01, a remarkable difference is not seen in an effect.

  Moreover, it is preferable to have the heat insulation layer which consists of metal sheets. By laminating metal sheets, effective heat insulation and heat retention are exhibited, so that fatigue due to heat loss of the user can be reduced. The material for the metal sheet is preferably a titanium alloy, but gold, silver, aluminum, lead, or the like may be used.

  The plate-like body is preferably formed in a polygonal shape in plan view. By forming in a polygonal shape, the sides of one plate-like body and the sides of the other plate-like body can be brought together so that they can be laid and arranged so as not to overlap each other.

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG.1 and FIG.2, the auxiliary tool for underwater exercise | movement of this embodiment has the hexagonal plate-shaped body 1 as a basic element. The area of the hexagonal plate-like body plane is 100 to ²⁰⁰ cm ^2, and is about the size of the palm of the hand. The thickness of the plate-like body is about 1 cm, but is not limited to this. Further, the shape of the plate-like body is not limited to a hexagon, and may be formed in a polygonal shape in plan view, such as a rhombus, a triangle, or a quadrangle as shown in FIG. By forming in a polygonal shape, as shown in FIG. 4, the sides of one plate-like body 1 and the sides of the other plate-like body 1 are put together and arranged so as not to overlap each other. Can do.

  Moreover, as shown in FIG. 3, the plate-like body 1 has a heat insulating layer 3 made of a metal sheet on both sides of a flexible elastic foam layer 2, and a stretchable fabric 4 on the outside thereof. It is constituted by. Each layer is appropriately fixed by an arbitrary adhesive or pressure-sensitive adhesive, but may be fixed by other means.

  The elastic foam layer 2 has a closed cell structure, is highly foamed and lightweight, and has high buoyancy. The closed cells are formed by foaming with a foaming agent. The specific gravity with respect to water as the whole plate-shaped body 1 shall be 0.01-0.1. This high buoyancy allows the user's body to float in water.

  The elastic foam layer 2 is formed by laminating a second elastic foam layer 2b made of rubber on both front and back surfaces of the first elastic foam layer 2a made of ethylene vinyl acetate (EVA) or vinyl chloride resin (PVC). It consists of a composite layer. In addition, it is not limited to this, The single layer structure of any one of the 1st elastic foam layer 2a or the 2nd elastic foam layer 2b may be sufficient. Moreover, as a raw material of the 1st elastic foam layer 2a, other raw materials, such as a polypropylene (PP) and polyethylene (PE), may be used, and what mixed these may be used. The thickness of the first elastic foam layer 2a is about 0.8 mm, but is not limited thereto.

  The material of the second elastic foam layer 2b may be either natural rubber or synthetic rubber. Synthetic rubbers such as chloroprene rubber (CR), urethane rubber, styrene butadiene rubber (SBR), acrylonitrile butadiene rubber (NBR), acrylonitrile rubber (NRP), butadiene rubber (BR), isoprene rubber (IR), etc. Examples include, but are not limited to, polymers or a mixture of these. Moreover, although the thickness of the 2nd elastic foam layer 2b shall be about 0.1 mm, it is not limited to this.

  The heat insulation layer 3 is a metal sheet, and specifically, a titanium alloy sheet is used. The metal sheet is an ultra-thin film with a thickness of about 70 microns, and by bonding and laminating it, effective heat insulation and heat retention are exhibited, so fatigue due to heat loss of the user Can be reduced. Moreover, since the heat insulation layer 3 is thin, it is flexible and can follow the movement of the body. The material for the metal sheet is not limited to the titanium alloy, and other metal materials such as gold, silver, aluminum, and lead may be used.

  As the front and back stretchable fabric 4, a nylon or polyester jersey fabric is used, but a fabric or knitted fabric rich in stretch using synthetic fibers or natural fibers may also be used. The stretchable fabric 4 can follow the movement of the body due to its stretchable nature. The thickness of the stretchable fabric 4 is 0.2 to 1.5 mm, but is not limited thereto.

  A method of using the underwater exercise aid 1 having the above configuration will be described. The number of the plate-like bodies 1 and the place where the plate-like body 1 is put are adjusted according to the user's level, body shape, necessary location and the like. Basically, it is only necessary to put the plate-like body 1 only on the front side of the body torso, but for those who are not good at swimming, it can be put on both the front side and the back side of the body, / Or just put it in the foot cover.

  For example, in the case of a standard-type adult female who cannot swim at all, as shown in FIGS. 4 and 5, seven plate-like bodies 1 are sandwiched between the swimsuit X and the skin on the front and the back of the trunk, respectively. . At this time, as shown in FIG. 7, it is arranged so as to focus on the position from the thymus to Tanda. Then, the sides are put together and spread so that the plate-like bodies 1 do not overlap each other. In addition, since the area becomes large in the case of a thick person, a tall person, and a man, the number of the plate-like bodies 1 should be increased correspondingly. In the case of a standard-type adult male, it is sufficient to put about 10 pieces on each of the front and back sides. In addition, since the area is small in the case of a slender person, a short person, or a child, the number of plate-like bodies 1 may be reduced. In the case of a type of swimsuit that covers up to the hands and / or feet, as shown in FIG. 9, the plate-like body 1 may be attached to the hand covering portion and / or the foot covering portion.

  By using the plate-like body 1, buoyancy acts on the user in water. As shown to Fig.8 (a), the position of the gravity center in water becomes good, and it can balance. If it can float in water in a well-balanced manner, the limbs are free and the user can swim. In this state, continue swimming for a while and learn the right balance. The number of the plate-like bodies 1 is gradually reduced as the swimming becomes better. And finally, it becomes possible to swim without the plate-like body 1.

  Thus, since the plate-like body 1 of the present invention is not sewn to the swimsuit X, the number of plate-like bodies 1 to be used can be increased or decreased. Training according to the level at that time becomes possible, and swimming progress is quick.

  In addition, the plate-like body 1 is relatively small in size and with the palm spread. Therefore, since this can be arranged between the swimsuit X and the skin so as not to overlap each other, the line hardly affects the appearance. Also, it can follow the skin according to the curve and movement of the body. Therefore, the adhesiveness with the body is higher than that with a single large shape, and buoyancy can be given evenly and uniformly to the body.

  In addition, in the case of a person with low physical strength such as an elderly person, it is easy to consume energy if the breath is stopped underwater. However, when the underwater exercise aid 1 of the present invention is used, the user can be given buoyancy that does not wet his face. Therefore, since the face can always be raised on the surface of the water, it can be suitably used for people with low physical strength such as elderly people.

  Also, for people with low physical strength such as elderly people, exercise in water for a long time is not preferable because the body cools down. However, since the underwater exercise aid 1 has the heat insulation layer 3, it can exhibit effective heat insulation and heat retention. Therefore, by using the auxiliary equipment for underwater exercise 1 between the swimsuit X and the skin, it is possible to reduce fatigue due to heat loss of the user. Therefore, it is possible to exercise in water for a relatively long time.

  A person with a physical disability can adjust and use the place to put the auxiliary equipment 1 for underwater exercise. For example, when the right half of the body does not move, the right half of the body sinks. Therefore, the underwater exercise assisting tool 1 can be placed only on the right side of the body, or the underwater exercise assisting tool 1 can be placed on the right side of the body more than on the left side of the body. Once balanced, the right leg, which had always been sinking, will rise above the water. When swimming in this state, the right leg is given a kicking force, so that all of the underwater exercise aids 1 can be removed and the swim can be maintained while maintaining a balance, and the time can be extended.

  People who suddenly become physically disabled due to traffic accidents, etc. have a heavy physical burden on the ground, and rehabilitation is difficult. Therefore, exercise in the water with less burden is suitable, but there is a fear of drowning due to physical inconvenience. Therefore, by using the auxiliary equipment for underwater exercise 1, it is possible to obtain a sense of security due to its buoyancy, and it is possible to actively work on underwater exercise and rehabilitation.

  In addition, even a person who is good at swimming may have a position of the center of gravity of the body shifted. Therefore, the balance in water is improved by putting the required number of plate-like bodies 1 in places where buoyancy is desired. The speed can be further increased by learning the good balance state with a sense.

  Moreover, at the time of aquabics, it is possible to exercise in a correct posture with the body leaning forward so as to resist the resistance of water by the buoyancy of the underwater exercise assisting tool 1. Therefore, it is possible to prevent an elderly person with low muscular strength from being burdened on the waist due to losing resistance to water and warping backward.

  Thus, the auxiliary tool for underwater exercise 1 of the present invention can give buoyancy to the user by the elastic foam layer 2 having buoyancy. In addition, the buoyancy is adjusted by increasing or decreasing the number of auxiliary tools to be used because it is detachably attached to the inner surface of the swimsuit X, for example, by sandwiching it between the swimsuit X and the skin without sewing it You can change the place where buoyancy is applied by changing the place where the auxiliary tool is put.
