  In another example of the present invention, the area of the resistance base is in the range of 3000 to 5200 cm 2, the opening area of the first opening area is in the range of 5 to 8% with respect to the area of the resistance base, and the second and third The opening area of the opening area is in the range of 10 to 25% with respect to the area of the resistance base.

  In another example of the present invention, the resistance base is connected to the longitudinal tip of the first opening area, and is connected to the longitudinal slit of the second opening area. And a second slit that opens from the outer peripheral edge in the longitudinally outward direction and a third slit that opens from the outer peripheral edge toward the longitudinally outward direction, connected to the longitudinal tip of the third opening area.

  In another example of the present invention, the resistance base includes a front surface and a rear surface having a predetermined area, a first resistance flange extending forward and backward in the longitudinal and transverse directions from the front surface along the outer peripheral edge, and a rear surface along the outer peripheral edge. A second resistance flange extending rearward in the front-rear direction intersecting the vertical and horizontal directions.

  In another example of the present invention, the resistance variable plate is formed on both side edges thereof, and protrudes laterally outward from the side edges, and urging means for urging the protrusions laterally outward. A guide rail that supports both side edges of the variable plate and slidably slides the variable plate, and a plurality of convex portions and concave portions that are formed on the guide rail and are alternately arranged in the vertical direction. In the underwater training and rehabilitation exercise equipment, when the convex part of the variable plate rides on the convex part of the guide rail, the convex part of the variable plate moves inward in the lateral direction against the biasing means, and the variable plate When the convex portion of the guide plate moves over the convex portion of the guide rail and is positioned in the concave portion of the guide rail, the convex portion of the variable plate is moved laterally outward by the urging means and is fitted into the concave portion of the guide rail. By opening those opening areas Area can be stepwise changed.

  Another example of the present invention is an elastically deformable leaf spring in which the urging means is defined by a slit formed inside the side edge of the variable resistance plate and extends between both ends of the slit, and the convex portion is a plate. Made in the approximate center of the spring.

  In another example of the present invention, the resistance base has a hand insertion opening formed in the vertical direction and extending in the lateral direction, and a hand grip is formed on the opposite side of the resistance base across the hand insertion opening, A first swivel rod located on the front side of the resistance base and extending laterally outward from the lateral center of the handgrip and capable of pivoting longitudinally and laterally about the lateral center; and on the rear surface side of the resistance base A second swivel rod positioned and extending laterally outward from the lateral center of the handgrip and pivotable longitudinally and laterally about the lateral center, wherein the first and From the state in which the second swivel rod is swung in the horizontal direction, the first and second swivel rods are swung in the vertical direction around the center in the horizontal direction, and the swivel rods are opposed to each other to form a vertically long handgrip extending in the vertical direction.

Formed from.

  In another example of the present invention, the outer peripheral edge of the resistance base is arced so as to protrude from the hand grip toward the opening area.

  According to the underwater training / rehabilitation exercise apparatus according to the present invention, the resistance base is swung back and forth in the water while the resistance base is in the water while holding the handgrip. Since the water pressure (water resistance) acts, not only can the muscles of the user's entire upper arm and the entire forearm be strengthened, but the opening area of the opening area arranged in the lateral direction can be varied from fully open to fully closed by the resistance variable plate. The pressure acting on the resistance base can be partially changed, so that a specific part of the user's upper arm or forearm can be loaded, so that specific muscles of the upper arm or forearm can be individually applied. Can be strengthened. Underwater training and rehabilitation exercise equipment can apply specific loads to specific parts of the user's upper arm and forearm, so it is possible to rehabilitate specific parts of the broken arm and the disabled (users) It is possible to perform rehabilitation of a specific part where an arm disorder remains. Underwater training and rehabilitation exercise equipment can be used easily at the time of bathing at home, so it can eliminate lack of exercise, disuse atrophy caused by lack of exercise and exercising (degenerate muscles not used) It is also possible to effectively prevent the joint that does not move from becoming unmovable. Since the water pressure is proportional to the square of the speed, not only can the user's upper arm and forearm muscles be strengthened by swinging the resistance base quickly in water, but the resistance base can be slowly By swinging, it is possible to perform training and rehabilitation according to the level of the user's muscle strength, the degree of failure, the degree of failure of the disabled person (user), and the like.

  The first to fifth opening areas and the first to fifth resistance variable plates arranged in the lateral direction are provided, and the opening area when these opening areas are fully opened is first to third opening areas> fourth and fifth opening areas. A certain underwater training / rehabilitation exercise device can change the opening area of the first to fifth opening areas from fully open to fully closed by the first to fifth resistance variable plates. By changing to, the hydraulic pressure acting on the resistance base can be partially changed, it is possible to apply a load to specific parts of the user's upper arm and forearm, and individually strengthen only specific muscles of the upper arm and forearm can do. In addition, it is possible to apply a load only to a specific part of a broken arm or only a specific part where a handicapped person (user) has a disability, and adjust the load applied to the specific part by changing the opening area. Therefore, the specific part of the broken arm can be rehabilitated, and the specific part where the handicapped person (user) remains in the arm can be rehabilitated. In the underwater training / rehabilitation exercise apparatus, the opening area of the first to third opening areas is larger than that of the fourth and fifth opening areas, and the water in the center of the resistance base is opened by opening the first to third opening areas. Therefore, it is possible to greatly reduce the water pressure acting on the center of the resistance base, and to perform training and rehabilitation tailored to users with poor arm strength.

  The first opening area is plane-symmetric with respect to a virtual vertical center line that bisects the resistance base in the lateral direction, and the second and third opening areas are positioned symmetrically with respect to the virtual vertical center line, and the fourth and fifth Underwater training and rehabilitation exercise equipment in which the opening area is located symmetrically with respect to the virtual vertical center line can apply the hydraulic pressure evenly in the lateral direction around the center of the resistance base. The exercise apparatus does not become unstable, can prevent sideways shake and rotation of the exercise apparatus during use, and can improve the usability of the exercise apparatus. The underwater training / rehabilitation exercise equipment can be adjusted to an exercise equipment in which the water pressure acts on the resistance base evenly by changing the opening areas of the second and third opening areas and the fourth and fifth opening areas equally. In addition, by changing the opening areas of these opening areas to be different, it is possible to adjust to the exercise equipment in which the water pressure acts on the resistance base in various ways.

  An underwater training / rehabilitation exercise device in which the area of the resistance base is in the range of 3000 to 5200 cm 2 and the opening area of the first to fifth opening areas is in the range of 5 to 8% of the area of the resistance base is Since the acting water pressure is proportional to the area of the resistance base, adjusting the area of the resistance base within the above range can make high resistance exercise equipment and low resistance exercise equipment. The exercise equipment according to the level of the person). In the underwater training / rehabilitation exercise equipment, the opening area of the first to fifth opening areas is in the above ratio with respect to the area of the resistance base, so changing the opening area to the opening area ensures the water pressure acting on the resistance base. In addition to being able to apply a load only to specific parts of the user's upper arm and forearm, only specific muscles of the upper arm and forearm can be individually strengthened. In addition, it is possible to perform rehabilitation only on a specific part of the broken arm, and it is possible to perform rehabilitation only on a specific part where the handicapped person (user) remains in the arm.

  The underwater training / rehabilitation exercise apparatus having first to fifth slits in which the resistance base opens from the outer peripheral edge thereof in the longitudinal direction outward is used when the first to fifth opening areas are fully closed. Although a large water pressure acts on the first to fifth resistance variable plates that block the area, the water that collides with the first to fifth resistance variable plates during use of the exercise apparatus is moved from the first to fifth slits to the outside of the resistance base. Since it can escape, the hydraulic pressure which acts on each resistance variable plate can be reduced, and breakage and deformation of each resistance variable plate during use of the exercise equipment can be prevented.

  Underwater training that includes first to third opening areas and first to third resistance variable plates arranged in the lateral direction, and the opening areas when the opening areas are fully open are second and third opening areas> first opening area. -Since the rehabilitation exercise device can change the opening area of the first to third opening areas from the fully open to the fully closed by the first to third resistance variable plates, the opening area can be individually changed for each of the opening areas. It is possible to partially change the water pressure acting on the resistance base, to load specific parts of the user's upper arm and forearm, and individually strengthen only specific muscles of the upper arm and forearm it can. In addition, it is possible to apply a load only to a specific part of a broken arm or only a specific part where a handicapped person (user) has a disability, and adjust the load applied to the specific part by changing the opening area. Therefore, the specific part of the broken arm can be rehabilitated, and the specific part where the handicapped person (user) remains in the arm can be rehabilitated. In the underwater training / rehabilitation exercise apparatus, the opening area of the second and third opening areas located in the center is larger than that of the first opening area, and by opening the second and third opening areas, Since water resistance can be reduced, the water pressure acting on both sides of the resistance base can be greatly reduced, and training and rehabilitation can be performed for users with poor arm strength.

  Underwater training and rehabilitation in which the first opening area is plane symmetric with respect to the virtual vertical center line that bisects the resistance base in the lateral direction, and the second and third opening areas are positioned symmetrically with respect to the virtual vertical center line The exercise equipment can apply water pressure evenly in the lateral direction centered on the center of the resistance base, so that the exercise equipment does not become unstable when using the exercise equipment. Rotation can be prevented and usability of the exercise equipment can be improved. The underwater training and rehabilitation exercise equipment can be adjusted to exercise equipment in which the water pressure acts on the resistance base evenly by changing the opening areas of the second and third opening areas evenly. Can be adjusted to exercise equipment in which the water pressure acts on the resistance base in various ways.

  The area of the resistance base is in the range of 3000 to 5200 cm 2, the opening area of the first opening area is in the range of 5 to 8% of the area of the resistance base, and the opening area of the second and third opening areas is the resistance base Underwater training and rehabilitation exercise equipment in the range of 10 to 25% of the area of the water, since the water pressure acting on the resistance base is proportional to the area of the resistance base, by adjusting the area of the resistance base in the above range, A high resistance exercise device or a low resistance exercise device can be made, and an exercise device according to the level of a user or a disabled person (user) can be obtained. In the underwater training / rehabilitation exercise equipment, the opening area of the first to third opening areas is in the above ratio with respect to the area of the resistance base, so changing the opening area to the opening area ensures the water pressure acting on the resistance base. In addition to being able to apply a load only to specific parts of the user's upper arm and forearm, only specific muscles of the upper arm and forearm can be individually strengthened. In addition, it is possible to perform rehabilitation only on a specific part of the broken arm, and it is possible to perform rehabilitation only on a specific part where the handicapped person (user) remains in the arm. Since the underwater training / rehabilitation exercise apparatus can reduce the resistance of water on both sides of the resistance base by opening the second and third opening areas, the water pressure acting on both sides of the resistance base can be greatly reduced. It is possible to perform training and rehabilitation tailored to users with weak arm strength.

  The underwater training / rehabilitation exercise apparatus having first to third slits whose resistance base opens from the outer peripheral edge thereof in the longitudinally outward direction is used when the first to third opening areas are fully closed. A large water pressure acts on the first to third resistance variable plates that block the area, but the water that collides with the first to third resistance variable plates during use of the exercise apparatus is moved from the first to third slits to the outside of the resistance base. Since it can escape, the hydraulic pressure which acts on each resistance variable plate can be reduced, and breakage and deformation of each resistance variable plate during use of the exercise equipment can be prevented.

  Underwater having a first resistance flange extending forward and backward in the longitudinal direction intersecting the longitudinal and lateral directions from the front surface along the outer peripheral edge and a second resistance flange extending backward and forward in the longitudinal direction intersecting the longitudinal and lateral directions from the rear surface along the outer peripheral edge. Training and rehabilitation exercise equipment can prevent water from escaping from the outer periphery of the resistance base during use of the exercise equipment, and the resistance base catches water, so that water pressure can be reliably applied to the resistance base. The user's upper arm and forearm muscles can be reliably strengthened.

  When the convex part of the variable plate rides on the convex part of the guide rail, the convex part of the variable plate moves inward in the lateral direction against the biasing means, and the convex part of the variable plate gets over the convex part of the guide rail. When the convex portions of the variable rails are positioned in the concave portions of the guide rails, the convex portions of the variable plates are moved laterally outward by the urging means and fitted into the concave portions of the guide rails. The underwater training and rehabilitation exercise equipment that can be changed to the above can be finely changed the opening area of the opening area by these variable plates, so that only specific muscles of the upper arm and forearm can be individually strengthened and failed Rehabilitation can be performed only on specific parts of the arm, and rehabilitation only on specific parts where the handicapped person (user) remains disabled .

  The biasing means is an elastically deformable leaf spring which is defined by a slit made inside the side edge of the resistance variable plate and extends between both ends of the slit, and the convex portion is made at substantially the center of the leaf spring. The underwater training and rehabilitation exercise equipment has a structure in which the convex part of the resistance variable plate moves inward in the lateral direction by the elastic force of the leaf spring when the convex part of the variable plate gets over the convex part of the guide rail and is positioned in the concave part of the guide rail. Since the opening area of the opening area can be changed step by step by the resistance variable plate by not only being able to change the opening area of the opening area. The movement of the variable resistance plate is regulated by the elastic force of the leaf spring, and the fluctuation of the opening area due to the inadvertent movement of the variable resistance plate can be prevented. Can hold it in a predetermined.

  The first and second swirling rods are swung in the vertical direction, and the swiveling rods are opposed to each other to form a vertically long handgrip extending in the vertical direction. The first and second swirling rods swung in the vertical direction are laterally moved. Underwater training and rehabilitation exercise equipment that forms a horizontal handgrip that extends in the horizontal direction by swiveling is a state in which the user has changed the way the user holds the vertical handgrip or horizontal handgrip with his / her hand Can use exercise equipment, and can train the upper arm and forearm according to the type of each sport. Moreover, when using for rehabilitation, a handicapped person (user) can select the holding method which is hard to feel pain, and can perform rehabilitation without difficulty.

  The resistance base has a band that pushes the user's hand toward the base, and the band is formed from a first band that is in close contact with the back of the user's hand and a second band that is in close contact with the user's middle finger. Since the rehabilitation exercise device can hold the exercise device in the state where the user's hand is fixed to the exercise device and the palm is opened by the first and second bands, It is possible to perform training corresponding to sports other than gripping a horizontally long handgrip, and rehabilitation can be performed with the palm open.

  Underwater training and rehabilitation exercise equipment that has an arc so that the outer periphery of the resistance base protrudes from the handgrip toward the opening area, the resistance-based planar shape of the resistance base is changed to the shape of the hand according to the length of each finger of the user. Since it can be approximated, the hydraulic pressure acting on the resistance base can be changed according to the shape of the hand, and only specific muscles of the upper arm and forearm can be strengthened accurately, and the handicapped (user) Rehabilitation can be reliably performed only on a specific part where the arm disorder remains.

It is a rear view of 10A of underwater training and rehabilitation exercise equipment shown in the fully open state. FIG. 1 shows a state in which the first to fifth opening areas 15a to 15e are closed (fully closed) by the first to fifth resistance variable plates 16a to 16e. In FIG. 1, the vertical direction is indicated by an arrow A, and the horizontal direction is indicated by an arrow B. 4 to 6, the front-rear direction is indicated by an arrow C, the front-rear direction front is indicated by an arrow C1, and the rear direction is indicated by an arrow C2. In the state of FIG. 8 in which the first to fifth opening areas 15a to 15e are fully opened, the entire first to fifth resistance variable plates 16a to 16e are accommodated in the first to fifth accommodation areas 24a to 24e.

  The underwater training / rehabilitation exercise apparatus 10 </ b> A includes a resistance base 11 having a predetermined area and a hand grip 12 connected to the resistance base 11. In the underwater training / rehabilitation exercise apparatus 10A, a user (handicapped person) grips the handgrip 12 with his hand and swings the resistance base 11 in a state where the resistance base 11 is placed in the water. By using (water resistance), it can be used for training aimed at strengthening the user's arm and can be used for rehabilitation aimed at restoring the function of the arm.

  The resistance base 11 and the hand grip 12 are made of a thermoplastic synthetic resin (preferably polypropylene). The resistance base 11 and the hand grip 12 are integrally formed. The resistance base 11 has a front surface 13 and a rear surface 14 having a predetermined area, and includes first to fifth opening areas 15a to 15e having a predetermined area and first to fifth resistance variable plates 16a to 16e having a predetermined area. Yes. The first to fifth resistance variable plates 15 a to 15 e are made of the same thermoplastic synthetic resin as the resistance base 11 and the hand grip 12.

  The outer peripheral edge 17 of the resistance base 11 forms an arc (arc) so as to protrude from the hand grip 12 toward the first to fifth opening areas 15a to 15e. The resistance base 11 has a planar shape formed in a substantially semicircular shape. A hand insertion opening 18 is formed (perforated) below the resistance base 11 in the vertical direction (lower part), which extends in the horizontal direction and allows the user's hands (four fingers excluding the thumb) to be inserted and removed. .

  Band fixing holes 20 for fixing the first band 19 are formed (perforated) on the laterally lower side (lower part) of the resistance base 11 and on the lateral sides of the hand insertion opening 18, and the first band is formed in the band fixing hole 20. 19 is fixed at both ends. The first band 19 is made of a material such as stretchable rubber or elastomer or a non-stretchable material, and extends in the lateral direction below the front surface 13 of the resistance base 11. The first band 19 presses the back of the hand against the front surface 13 of the resistance base 11 while closely contacting the back of the user's hand, and fixes the user's hand to the resistance base 11.

  A band fixing hole 22 for fixing the second band 21 is formed (perforated) in the longitudinal center (central part) of the resistance base 11, and both ends of the second band 21 are fixed to the band fixing hole 22. The second band 21 is made of a material such as stretchable rubber or elastomer or a non-stretchable material, and extends in the lateral direction at the longitudinal center of the front surface 13 of the resistance base 11. The second band 21 presses the middle finger against the front surface 13 of the resistance base 11 while being in close contact with the middle finger of the user, and fixes the middle finger of the user to the resistance base 11.

  The area of the resistance base 11 is in the range of 3000 to 5200 cm2. If the area of the resistance base 11 is less than 3000 cm 2, the area of the resistance base 11 is small, the hydraulic pressure acting on the resistance base 11 is low, and the necessary load cannot be applied to the muscles of the user's arm, strengthening the arm. Cannot perform rehabilitation for the purpose of training or recovery of arm function. When the area of the resistance base 11 exceeds 5200 cm 2, an excessive water pressure acts on the resistance base 11, making it difficult to swing the resistance base 11 in water, and training and rehabilitation cannot be performed efficiently.

  The first to fifth opening areas 15 a to 15 e are formed in the vertical direction (upper part) of the resistance base 11 and extend in the vertical direction from the vicinity of the outer peripheral edge 17 of the resistance base 11 toward the hand grip 12. The first opening area 15a opens upward (upper) in the center of the resistance base 11, and the second and third opening areas 15b and 15c are above the resistance base 11 in the vertical direction, and the first opening area 15a. It is open on both sides in the horizontal direction.

The upper opening is open laterally outside the third opening 15c (on the side of the resistance base 11).

  The second and third opening areas 15b and 15c are arranged along the outer peripheral edge 17 of the resistance base 11 at the same distance from the first opening area 15a and arranged laterally outside, and the virtual vertical length that bisects the resistance base 11 in the horizontal direction. It is located symmetrically with respect to the center line L. The fourth and fifth opening areas 15d, 15e are arranged laterally outwardly at equal intervals from the second and third opening areas 15b, 15c along the outer peripheral edge 17 of the resistance base 11, and are aligned with the virtual vertical center line L. They are located symmetrically. The first opening area 15a has a rectangular shape whose plan shape is long in the vertical direction. The second to fifth opening areas 15 b to 15 e have a substantially quadrangular plan shape that is long in the vertical direction, and the upper edge is curved along the outer peripheral edge 17 of the resistance base 11.

  The first to third opening areas 15a to 15c have substantially the same opening area size when fully opened, and the fourth and fifth opening areas 15d and 15e have the opening area size when fully opening. Are the same. The size of the opening area when the opening areas 15a to 15e are fully opened is that the first to third opening areas 15a to 15c are larger than those of the fourth and fifth opening areas 15d and 15e. 3 opening areas 15a to 15c> fourth and fifth opening areas 15d and 15e.

  By closing (full closing) the first to fifth opening areas 15a to 15e, the strength of the water pressure acting on the resistance base 11 is maximized, and the first to fifth opening areas 15a to 15e are opened (full opening). By doing so, the strength of the water pressure acting on the resistance base 11 is minimized. By opening the first opening area 15a, the water pressure acting on the center of the resistance base 11 is reduced, and by opening the second and third opening areas 15b, 15c, the pressure acts on both sides of the center of the resistance base 11. While the water pressure is reduced, the water pressure acting on both sides of the resistance base 11 is reduced by opening the fourth and fifth opening areas 15d and 15e.

  The opening areas of the first to fifth opening areas 15a to 15e are in the range of 5 to 8% with respect to the area of the resistance base 11 (the area of the front surface 13 or the area of the rear surface 14). If the opening area of the first to fifth opening areas 15a to 15e is less than 5% of the area of the resistance base 11, even if each opening area 15a to 15e is opened and closed, the strength of the water pressure acting on the resistance base 11 is expected. It is difficult to increase or decrease it. When the opening area of the first to fifth opening areas 15a to 15e exceeds 8% of the area of the resistance base 11, when each opening area 15a to 15e is opened and closed, the resistance in which the closed opening areas 15a to 15e exist is present. The difference in water pressure between the base 11 part and the resistance base 11 part where the open open areas 15a to 15e are present becomes larger than necessary, and the exercise apparatus 10A may sway or rotate underwater during use. In some cases, the exercise apparatus 10A cannot be accurately swung. Moreover, when each opening area 15a-15e is open | released (fully opened), the water pressure which acts on the resistance base 11 is weak, and a load cannot be applied to a user's arm.

Then, a fourth slit 23d is formed in the outer peripheral edge 17 of the resistance base 11 facing the fourth opening area 15d. The fourth slit 23d opens from the outer peripheral edge 17 to the outer side in the vertical direction. Perforated). A fifth slit 23e is formed (perforated) on the outer peripheral edge 17 of the resistance base 11 that faces the fifth opening area 15e.

  FIG. 12 is a front view of the underwater training / rehabilitation exercise apparatus 10A showing an example of the use state, and FIG. 13 is a rear view of the underwater training / rehabilitation exercise apparatus 10A in the use state of FIG. FIG. 14 is a front view of the underwater training / rehabilitation exercise apparatus 10A in which the first and second swiveling rods 37, 38 are swung in the vertical direction, and FIG. 15 is a front view of the first and second swiveling rods 37, 38 in the vertical direction. It is a front view of 10A of underwater training and rehabilitation exercise equipment after turning in a direction. FIG. 16 is a front view of an underwater training / rehabilitation exercise apparatus 10A showing another example of the use state, and FIG. 17 is a front view of the underwater training / rehabilitation exercise apparatus 10A showing another example of the use state.

  In FIGS. 12-16, illustration of water is abbreviate | omitted. 14 and 15, the first and second bands 19 and 21 are shown broken away. 12 to 16, the first to fifth opening areas 15a to 15e are fully closed, but the illustration in the case where the first to fifth opening areas 15a to 15e are fully opened or opened with a predetermined area is omitted. 12 to 16, the front in the front-rear direction is indicated by an arrow C1, and the rear in the front-rear direction is indicated by an arrow C2.

  In the underwater training / rehabilitation exercise device 10 </ b> A, the first and second swiveling rods 37, 38 are swung in the lateral direction, and the swiveling rods 37, 38 are parallel to the handgrip 12, thereby extending the horizontally long handgrip 45. Is formed. An example of the use of the underwater training / rehabilitation exercise apparatus 10A is as shown in FIGS. 12 and 13, in which the user (disturbance) is inserted into the hand insertion opening 18 with the first and second swiveling rods 37 and 38 being swung laterally. A person) inserts his / her hand 46 (four fingers excluding the thumb) and holds (holds) the horizontal handgrip 45 with the hand 46 to hold the exercise device 10 </ b> A with the hand 46.

  Next, the resistance base 11 is put in water, the wrist is swung while the horizontally long handgrip 45 is being gripped, and the resistance base 11 is swung continuously forward and backward in water in the front-rear direction. The front surface 13 and the rear surface 14 of the resistance base 11 serve as water scraping, and water pressure (water resistance) acts on the front and rear surfaces 13, 14 of the resistance base 11, and the water pressure (load) acts on the upper arm and forearm of the user. While using the exercise apparatus 10A, the user (disabled person) moves the operation knob 33 with his / her finger and moves the knob 33 upward or downward in the vertical direction to move the first to fifth resistance variable plates 16a to 16e. By sliding, the opening areas of the first to fifth opening areas 15a to 15e can be appropriately changed.

  In addition, since the first and second resistance flanges 29 and 30 prevent escape of water from the outer peripheral edge 17 of the resistance base 11 and the base 11 catches water during use of the exercise equipment 10A, the water pressure is reliably applied to the base 11. Can act. In addition, when the first to fifth opening areas 15a to 15e are fully closed, a large water pressure acts on the first to fifth resistance variable plates 16a to 16e that close the opening areas 15a to 15e. Since the water colliding with the first to fifth resistance variable plates 16a to 16e during use of 10A can be released to the outside of the resistance base 11 from the first to fifth slits 23a to 23e, the resistance variable plates 16a to 16e can be released. The hydraulic pressure acting on the resistance variable plates 16a to 16e can be prevented from being damaged or deformed during use of the exercise apparatus 10A.

  Another example of the use of the underwater training / rehabilitation exercise apparatus 10A is as shown by the arrow in FIG. 14 from the state in which the first and second swiveling rods 37, 38 are swung laterally to form the horizontally long handgrip 46. The distal end portion 41 of the first swiveling rod 37 is swung in the vertical direction around the lateral center (swivel axis 40) of the handgrip 12, and the distal end portion 44 of the second swivel rod 38 is laterally centered ( As shown in FIG. 15, the tip portions 41 and 44 of the turning rods 37 and 38 are opposed to each other as shown in FIG. When the tip portions 41 and 44 are opposed to each other, a vertically long handgrip 47 is formed by the turning rods 37 and 38. The first and second swivel rods 37 and 38 swung in the vertical direction are returned to the horizontally long handgrip 45 by swiveling again in the horizontal direction.

  As shown in FIG. 16, the user (handicapped person) holds (holds) the vertically long handgrip 47 with his hand 46 and holds the exercise device 10 </ b> A with the hand 46. Next, the resistance base 11 is put in water, the wrist is swung while the vertically long handgrip 47 is gripped, and the resistance base 11 is swung continuously forward and backward in water in the front-rear direction. The front surface 13 and the rear surface 14 of the resistance base 11 serve as water scraping, and water pressure (water resistance) acts on the front and rear surfaces 13, 14 of the resistance base 11, and the water pressure (load) acts on the upper arm and forearm of the user.

  Another example of the use of the underwater training / rehabilitation exercise apparatus 10A is as shown in FIG. 17, in the state where the first and second swiveling rods 37, 38 are swung sideways to form a horizontally long handgrip 46. A hand is inserted between the first band 19 and the horizontally long handgrip 46, and a middle finger is inserted between the second band 21 and the resistance base 11. The back of the user's handicapped person is pressed against the exercise equipment 10A by the elastic first band 19 and the back of the hand is fixed to the exercise equipment 10A, and the middle finger is pressed against the exercise equipment 10A by the elastic second band 21. Then, the middle finger is fixed to the exercise equipment 10A. Next, the resistance base 11 is put in water, the wrist is swung while the vertically long handgrip 47 is gripped, and the resistance base 11 is swung continuously forward and backward in water in the front-rear direction. The front surface 13 and the rear surface 14 of the resistance base 11 serve as water scraping, and water pressure (water resistance) acts on the front and rear surfaces 13, 14 of the resistance base 11, and the water pressure (load) acts on the upper arm and forearm of the user.

  In the underwater training / rehabilitation exercise device 10A, the user holds the horizontally long handgrip 45 or the horizontally long handgrip 47 with the hand 46, or the hand 46 is fixed to the exercise device 10A with the first and second bands 19, 21; A predetermined water pressure (water resistance) acts on the base 11 by swinging the base 11 back and forth in the water while the resistance base 11 is in the water. Of course, the opening areas of the first to fifth opening areas 15a to 15e arranged in the lateral direction by the first to fifth resistance variable plates 16a to 16e can be varied stepwise from fully open to fully closed. Because it is possible, the water pressure acting on the base 11 can be partially changed, thereby applying a load on a specific part of the user's upper arm or forearm. It is possible to strengthen the specific muscles of the upper arm and forearm separately.

  The underwater training / rehabilitation exercise device 10 </ b> A adjusts the opening areas of the first to fifth opening areas 15 a to 15 e by the first to fifth resistance variable plates 16 a to 16 e, so that specific parts of the upper arm and forearm of the user are adjusted. Therefore, it is possible to perform rehabilitation of a specific part of a broken arm, and it is possible to perform rehabilitation of a specific part where the handicapped person (user) remains in the arm. The underwater training / rehabilitation exercise apparatus 10A not only can further strengthen the upper arm and forearm muscles of the user by swinging the resistance base 11 quickly in the water, but also swings the base 11 slowly in the water. By doing so, it is possible to perform training and rehabilitation according to the level of the user's muscular strength, the degree of failure, the degree of failure of the disabled person (user), and the like.

  The underwater training / rehabilitation exercise equipment 10A is used by the user (handicapped person) holding the horizontally long handgrip 45 or the vertically long handgrip 47 with his / her hand 46 so that the user changes the way of holding it. The upper arm and the forearm can be trained according to the type of each sport. Moreover, when using for rehabilitation, the user (person with a disability) can select the way of holding that is difficult to feel pain, and rehabilitation can be performed without difficulty. In the underwater training / rehabilitation exercise device 10A, the hand 46 is fixed to the exercise device 10A by the first and second bands 19, 21 while the user (disabled person) opens the hand 46, and the hand 46 is opened. Since the exercise apparatus 10A can be held in a state, training corresponding to sports other than holding the horizontally long handgrip 45 or the vertically long handgrip 47 can be performed, and rehabilitation can be performed with the palm open.

FIG. 20 is a top view of the underwater training / rehabilitation exercise device 10B, and FIG. 21 is a rear view of the underwater training / rehabilitation exercise device 10B with the first to third opening areas being substantially half open. FIG. 22 is a rear view of the underwater training / rehabilitation exercise apparatus 10 </ b> B shown with the first to third opening areas fully opened.

  FIG. 18 shows a state in which the first to third opening areas 15a to 15c are closed (fully closed) by the first to third resistance variable plates 16a to 16c. In FIG. 18, the vertical direction is indicated by an arrow A and the horizontal direction is indicated by an arrow B. In FIG. 20, the front-rear direction is indicated by arrow C, the front-rear direction front is indicated by arrow C1, and the rear direction is indicated by arrow C2. In the state of FIG. 22 in which the first to third opening areas 15a to 15c are fully opened, the entire first to third resistance variable plates 16a to 16c are accommodated in the first to third accommodation areas 24a to 24c.

  The underwater training / rehabilitation exercise apparatus 10B is different from that shown in FIG. 1 in that the first to third opening areas 15a to 15c having a predetermined area and the first to third resistance variable plates having a predetermined area made of a thermoplastic synthetic resin. 16a to 16c, and other configurations are the same as those of the underwater training / rehabilitation exercise apparatus 10A in FIG. 1, and therefore, the same reference numerals as those of the exercise apparatus 10A are attached, and the exercise apparatus 10A is described. As a result, the detailed description of the other components of the exercise apparatus 10B will be omitted.

  The underwater training / rehabilitation exercise apparatus 10 </ b> B includes a resistance base 11 having a predetermined area whose planar shape is formed in a substantially semicircular shape, and a hand grip 12 connected to the resistance base 11. The area of the resistance base 11 is the same as that of the resistance base 11 of FIG. 1, and is in the range of 3000 to 5200 cm 2. A manual insertion opening 18 is formed below (in the lower part of) the resistance base 11 in the vertical direction. A first band 19 extending in the horizontal direction is attached to the lower side (lower part) of the front surface 13 of the resistance base 11, and a first band 19 extending in the horizontal direction is provided at the vertical center (central portion) of the front surface 13 of the resistance base 11. Two bands 21 are attached.

  The first to third opening areas 15 a to 15 c are formed in the vertical direction (upper part) of the resistance base 11 and extend in the vertical direction from the vicinity of the outer peripheral edge 17 of the resistance base 11 toward the hand grip 12. The first opening area 15 a is open upward (upper) in the vertical direction in the center of the resistance base 11. The second and third opening areas 15b and 15c are open above the resistance base 11 in the vertical direction and on both lateral sides of the first opening area 15a (side portions of the resistance base 11).

  The first opening area 15a has a rectangular shape whose plan shape is long in the vertical direction. The second and third opening areas 15b and 15c are arranged along the outer peripheral edge 17 of the resistance base 11 at the same distance from the first opening area 15a and arranged laterally outside, and the virtual vertical length that bisects the resistance base 11 in the horizontal direction. It is located symmetrically with respect to the center line L. The second and third opening areas 15 b to 15 c have a substantially square planar shape, and the upper edge is curved along the outer peripheral edge 17 of the resistance base 11.

  The second and third opening areas 15b and 15c have the same opening area size when fully opened. The size of the opening area when the opening areas 15a to 15c are fully opened is that the second and third opening areas 15b and 15c are larger than that of the first opening area 15a, and the second and third opening areas 15b, 15c> first opening area 15a.

  By closing (full closing) the first to third opening areas 15a to 15c, the strength of the water pressure acting on the resistance base 11 is maximized, and the first to third opening areas 15a to 15c are opened (fully opened). By doing so, the strength of the water pressure acting on the resistance base 11 is minimized. By opening the first opening area 15a, the water pressure acting on the center of the resistance base 11 is reduced, and by opening the second and third opening areas 15b and 15c, the water pressure acting on both sides of the resistance base 11 is reduced. It is reduced.

  The opening area of the first opening area 15a is in the range of 5 to 8% with respect to the area of the resistance base 11 (the area of the front surface 13 or the area of the rear surface 14), and the opening of the second and third opening areas 15b and 15c. The area is in the range of 10 to 25% with respect to the area of the resistance base 11 (the area of the front surface 13 or the area of the rear surface 14). When the opening area of the first opening area 15a is less than 5% of the area of the resistance base 11 and the opening areas of the second and third opening areas 15b and 15c are less than 10% of the area of the base 11, each opening area 15a˜ Even if 15c is opened and closed, it is difficult to increase or decrease the water pressure strength acting on the resistance base 11 to the expected level.

  When the opening area of the first opening area 15a exceeds 8% of the area of the resistance base 11, and the opening area of the second and third opening areas 15b and 15c exceeds 25% of the area of the base 11, each opening area 15a When opening and closing 15 c, the difference in water pressure between the portion of the resistance base 11 where the closed open areas 15 a to 15 c exist and the portion of the resistance base 11 where the opened open areas 15 a to 15 c exist is more than necessary. In some cases, the exercise equipment 10B may sway or rotate underwater during use, and the exercise equipment 10B may not be able to be accurately swung in the front-rear direction. Moreover, when each opening area 15a-15c is open | released (fully opened), the water pressure which acts on the resistance base 11 is weak, and a load cannot be applied to a user's arm.

  As shown in FIG. 20, the outer peripheral edge 17 facing the first opening area 15 a of the resistance base 11 is connected to the longitudinal tip of the opening area 15 a and opens from the outer peripheral edge 17 in the vertical outward direction. A slit 23 a is formed, and the second peripheral edge 17 facing the second opening area 15 b of the resistance base 11 is connected to the longitudinal tip of the opening area 15 and opens from the outer peripheral edge 17 in the vertical outward direction. 23b is formed. A third slit 23c is formed in the outer peripheral edge 17 of the resistor base 11 that faces the third opening area 15c. The third slit 23c is connected to the longitudinal tip of the opening area 15c and opens from the outer peripheral edge 17 outward in the vertical direction. .

  Below the first opening area 15a, a first accommodation area 24a for accommodating the first resistance variable plate 16a when the opening area 15a is opened is formed, and below the second opening area 15b, an opening area is formed. A second accommodation area 24b for accommodating the second variable resistance plate 16b is formed when 15b is opened. A third accommodation area 24c that accommodates the third resistance variable plate 16c when the opening area 15c is opened is formed below the third opening area 15c in the vertical direction. The first to third accommodation areas 24 a to 24 c are spaces defined between the front and rear surfaces 13 and 14 of the resistance base 11.

  Both side edges 25 of the first to third resistance variable plates 16a to 16c are supported on the vertical side edges that surround the first to third opening areas 15a to 15c and the first to third accommodation areas 24a to 24c. Thus, a guide rail 26 is slidably slidable on the variable plates 16a to 16c (refer to FIGS. 8 and 9). The guide rail 26 has a plurality of convex portions 27 and concave portions 28 that are alternately arranged in the vertical direction.

  A first resistance flange 29 is formed on the outer peripheral edge 17 of the front surface 13 of the resistance base 11 so as to extend forward in the front-rear direction from the front surface 13 along the curved shape of the outer peripheral edge 17. Is formed with a second resistance flange 30 extending rearwardly from the rear surface 14 along the curved shape of the outer peripheral edge 17. As shown in FIG. 20, the first resistance flange 29 repeats undulations so as to form an arc in the front-rear direction front and the front-rear direction rearward in the lateral direction, and the second resistance flange 30 faces the horizontal direction. Thus, the undulations are repeated in an undulating manner so as to form an arc forward and backward in the front-rear direction. A plurality of reinforcing ribs 31 extending in the vertical direction are formed on the front surface 13 of the resistance base 11, and a plurality of reinforcing ribs 32 extending in the vertical direction are formed on the rear surface 14 of the resistance base 11.

  The first variable resistance plate 16a has the same shape as the planar shape of the first opening area 15a, and its area (size) is slightly larger than that of the opening area 15a. The second and third variable resistance plates 16b and 16c have the same shape as the planar shapes of the second and third opening areas 15b and 15c, and their areas (sizes) are slightly larger than those of the opening areas 15b and 15c. . An operation knob 33 is provided on the first to third resistance variable plates 16a to 16c. The first to third resistance variable plates 16a to 16c are formed on both side edges 25 and project from the side edges 25 laterally outward, and urge the convex parts 34 laterally outward. It has the leaf | plate spring 35 (biasing means) (FIG. 9 assistance). The leaf spring 35 is the same as that of the exercise apparatus 10A.

  The first to third resistance variable plates 16a to 16c are slidably (movable) installed on the guide rails 26 formed in the first to third opening areas 15a to 15c and the first to third accommodation areas 24a to 24c. Then, the first to third opening areas 15a to 15c are opened and closed. The first to third resistance variable plates 16a to 16c move in the vertical direction along the guide rail 26 between the first to third opening areas 15a to 15c and the first to third accommodation areas 24a to 24c. By (sliding), the opening areas of the opening areas 15a to 15c are changed (changed) stepwise from fully open to fully closed. The movement mode (movement procedure) of the first to third resistance variable plates 16a to 16c is the same as that of the resistance variable plates 16a to 16e of FIG. The number of changes in the opening area in the first to third resistance variable plates 16a to 16c is the same.

  The hand grip 12 is formed on the opposite side of the resistance base 11 with the hand insertion opening 18 in between. The hand grip 12 is located on the front surface 13 side of the resistance base 11 and is located on the rear surface 14 side of the first turning rod 37 extending from the lateral center of the hand grip 12 outward in the lateral direction. And a second swivel rod 38 extending laterally outward from the lateral center of the handgrip 12. The first and second rods 37 and 38 are the same as those of the exercise apparatus 10A.

  FIG. 23 is a front view of the underwater training / rehabilitation exercise apparatus 10B showing an example of the use state, and FIG. 24 is a front view of the underwater training / rehabilitation exercise apparatus 10B showing another example of the use state. FIG. 25 is a front view of the underwater training / rehabilitation exercise apparatus 10B showing another example of the usage state. In FIGS. 23-25, illustration of water is abbreviate | omitted. In FIGS. 23 to 25, the first to third opening areas 15a to 15c are fully closed. However, the illustration in the case of using the first to third opening areas 15a to 15c with the fully open or predetermined area open is omitted. 23 to 25, the front in the front-rear direction is indicated by an arrow C1, and the rear in the front-rear direction is indicated by an arrow C2.

  As shown in FIG. 23, an example of the use of the underwater training / rehabilitation exercise apparatus 10B is a user (handicapped person) in the hand insertion opening 18 with the first and second swiveling rods 37 and 38 swung in the lateral direction. Inserts the hand 46, holds the horizontally long handgrip 45 with the hand 46, and holds the exercise apparatus 10B with the hand 46. Next, the resistance base 11 is put in water, the wrist is swung while the horizontally long handgrip 45 is being gripped, and the resistance base 11 is swung continuously forward and backward in water in the front-rear direction. The front surface 13 and the rear surface 14 of the resistance base 11 serve as water scraping, and water pressure (water resistance) acts on the front and rear surfaces 13, 14 of the resistance base 11, and the water pressure (load) acts on the upper arm and forearm of the user. The user (person with a disability) slides the first to third resistance variable plates 16a to 16c by using the finger to move the operation knob 33 in a timely manner or moving the knob 33 vertically upward or downward while using the exercise apparatus 10B. The opening areas of the first to third opening areas 15a to 15c can be changed as appropriate.

  In addition, since the 1st and 2nd resistance flanges 29 and 30 prevent escape of the water from the outer periphery 17 of the resistance base 11, and the base 11 catches water during use of the exercise equipment 10B, water pressure is reliably applied to the base 11. Can act. Further, when the first to third opening areas 15a to 15c are fully closed, a large water pressure acts on the first to third resistance variable plates 16a to 16c that close the opening areas 15a to 15c. Since the water colliding with the first to third resistance variable plates 16a to 16c during use of 10B can be released to the outside of the resistance base 11 from the first to third slits 23a to 23c, each of the resistance variable plates 16a to 16c. The hydraulic pressure that acts on the resistance variable plates 16a to 16c during use of the exercise apparatus 10B can be prevented.

  As shown in FIG. 24, another example of the use of the underwater training / rehabilitation exercise apparatus 10B is that the user (handicapped person) grasps (holds) the vertical handgrip 47 with his / her hand 46 and hands the exercise apparatus 10B. Hold at 46. Next, the resistance base 11 is put in water, the wrist is swung while the vertically long handgrip 47 is gripped, and the resistance base 11 is swung continuously forward and backward in water in the front-rear direction. The front surface 13 and the rear surface 14 of the resistance base 11 serve as water scraping, and water pressure (water resistance) acts on the front and rear surfaces 13, 14 of the resistance base 11, and the water pressure (load) acts on the upper arm and forearm of the user.

  Another example of the use of the underwater training / rehabilitation exercise apparatus 10B is to insert a hand between the first band 19 and the horizontally long handgrip 46 as shown in FIG. A middle finger is inserted between the first and second bands 19, 21 and the back of the user's (handicapped) hand and middle finger are fixed to the exercise device 10B. The wrist is swung while gripping the grip 47, and the resistance base 11 is swung continuously forward and backward in the front-rear direction in water. The front surface 13 and the rear surface 14 of the resistance base 11 serve as water scraping, and water pressure (water resistance) acts on the front and rear surfaces 13, 14 of the resistance base 11, and the water pressure (load) acts on the upper arm and forearm of the user.

  In the underwater training / rehabilitation exercise apparatus 10B, the user holds the horizontally long handgrip 45 or the horizontally long handgrip 47 with the hand 46, or the hand 46 is fixed to the exercise apparatus 10B with the first and second bands 19, 21; A predetermined water pressure (water resistance) acts on the base 11 by swinging the base 11 back and forth in the water while the resistance base 11 is in the water. Of course, the opening areas of the first to third opening areas 15a to 15c arranged in the lateral direction by the first to third resistance variable plates 16a to 16c can be varied stepwise from fully open to fully closed. Because it is possible, the water pressure acting on the base 11 can be partially changed, thereby applying a load on a specific part of the user's upper arm or forearm. It is possible to strengthen the specific muscles of the upper arm and forearm separately.

  The underwater training / rehabilitation exercise apparatus 10B adjusts the opening area of the first to third opening areas 15a to 15c by the first to third resistance variable plates 16a to 16c, thereby allowing the user's upper arm or forearm to be a specific part. Therefore, it is possible to perform rehabilitation of a specific part of a broken arm, and it is possible to perform rehabilitation of a specific part where the handicapped person (user) remains in the arm. The underwater training / rehabilitation exercise device 10B not only can further strengthen the upper arm and forearm muscles of the user by swinging the resistance base 11 quickly in the water, but also swings the base 11 slowly in the water. By doing so, it is possible to perform training and rehabilitation according to the level of the user's muscular strength, the degree of failure, the degree of failure of the disabled person (user), and the like.

  The underwater training / rehabilitation exercise device 10B is used by the user (person with a disability) holding the horizontally long handgrip 45 or the vertically long handgrip 47 with his / her hand 46 so that the user changes the way of holding it. The upper arm and the forearm can be trained according to the type of each sport. Moreover, when using for rehabilitation, the user (person with a disability) can select the way of holding that is difficult to feel pain, and rehabilitation can be performed without difficulty. In the underwater training / rehabilitation exercise device 10B, the hand 46 is fixed to the exercise device 10A by the first and second bands 19, 21 while the user (disabled person) opens the hand 46, and the hand 46 is opened. Since the exercise apparatus 10B can be held in a state, training corresponding to sports other than holding the horizontally long handgrip 45 or the vertically long handgrip 47 can be performed, and rehabilitation can be performed with the palm open.

  Since the underwater training / rehabilitation exercise apparatus 10B can reduce the resistance of water on both sides of the resistance base 11 by opening the second and third opening areas 15b, 15c, the water pressure acting on both sides of the base 11 can be reduced. It can be greatly reduced, and training and rehabilitation for users with poor arm strength can be performed.
