Description

The present invention uses air-guided hip fitness pants that inflate by the wearer's own operation when the wearer determines that there is a high risk of falling, thereby preventing the wearer from falling fracture.・ About pants.

In recent years, the number of accidents in which elderly people have a fracture of the proximal femur due to a fall has increased. The proximal part of the femur is the part of the femur near the pelvis (upper end). In particular, elderly people who develop osteoporosis or sarcopenia (a symptom of loss of muscle mass due to aging) have reduced walking ability, so they fall even indoors such as at home, and the impact of the fall causes the femur. Fractures may occur in the proximal part of the bone or the pelvis. For example, bone atrophy and decreased walking ability due to age-related degenerative changes such as postmenopausal osteoporosis and knee osteoarthritis induce falls, especially at night and in the early morning when moving to the toilet, which causes the femur. There are many cases in which fractures of the proximal part of the bone and the pelvis are caused.

Even if the above-mentioned fractures of the proximal femur and the like are surgically treated, it is not uncommon for the quality of life after surgery to be significantly reduced, especially in the elderly. For this reason, it is required to prevent fracture accidents due to falls, and various proposals have been made for that purpose.

For example, Patent Document 1 below discloses clothing provided with a shorts-type clothing body and a shock absorbing pad attached to the clothing body as clothing for preventing a fracture due to a fall. The shock absorbing pad is a pad made of an elastomer having a shock absorbing action, and is attached at a position facing the proximal part of the femur including the greater trochanter part.

International Publication No. 2015/064528

According to the technique of Patent Document 1, since the impact transmitted to the proximal femur when the adherend falls is alleviated by the impact absorbing pad, the effect of preventing the fracture of the proximal femur is expected. NS.

However, in Patent Document 1, since the shock absorbing pad is arranged so as to cover only the side surface of the upper part (or buttocks) of the thigh, the effect of preventing fracture may not be sufficiently exhibited. For example, when the wearer falls sideways, it is considered that the shock absorbing pad is interposed between the floor and the proximal part of the femur to obtain the expected shock absorbing effect, but depending on the posture at the time of falling. There was a risk that the shock absorbing pad did not intervene well between the floor and the proximal femur, and the impact applied to the proximal femur was not sufficiently absorbed. Also, even if the shock absorbing pad intervenes well between the floor and the proximal femur, the impact applied from the floor is only mitigated, so especially for elderly people who develop osteoporosis or sarcopenia. However, there was a possibility that a sufficient fracture prevention effect could not be obtained.

The present invention has been made in view of the above circumstances, and provides air-guided hip fitness pants capable of sufficiently reducing the risk of fracture of the proximal femur during a fall. The purpose.

In order to solve the above problems, the inventor of the present application wears pants-shaped clothing containing air-induced hip phytones, especially for elderly people who have developed osteoporosis or sarcopenia, to the proximal part of the femur. By air-guided hip fitness pants that prevent fractures, that is, inflate with air to prevent fractures during movements that increase the risk of the wearer's fall and squeeze around the hip joint (the joint between the pelvis and femur). It was devised to prevent fractures of the proximal femur by compressing and protecting the bones and muscles of the upper femur all around.

Specifically, the present invention is a pants body worn on the lower body of the wearer, and air is applied to the air-guided hip fitness provided inside the air-guided hip fitness pants and the air-guided hip fitness. The air supply device includes an air supply device for supplying and expanding the air-guided hip fitness, and the air supply device includes a controller and left and right air pumps continuous thereto (claim 1).

In the present specification, the "upper thigh" means the upper half (the half closer to the trunk) of the thigh (the part from the base of the leg to the knee).

Preferably, the thigh protection of the air-guided hip fitness pants has a plurality of cells that include a ring-shaped space along the peripheral surface of the upper thigh and are divided in the direction along the center line of the thigh. The air supply device expands the air-guided hip fitness by supplying air into the spaces of the plurality of cells (claim 2).

According to the present invention, an air-guided hip fitness including a thigh protection portion that surrounds the upper part of the thigh of the wearer in the circumferential direction is provided inside the body of the air-guided hip fitness pants, and the wearer falls over. When it is judged that the risk of Acts on. The inflated air-guided hip fitness presses the subject's upper thigh with sufficient pressure inward in the radial direction. As a result, the muscles of the upper part of the thigh are pressurized and adhered to the femur, so that the proximal part of the femur (the upper end part of the femur), which is prone to fracture during a fall, can be effectively reinforced. Then, the proximal part of the femur is formed by the synergistic effect of the reinforcing effect due to the close contact with the muscle and the shock absorbing effect between the cell expanded by the air inside the air-guided hip fitness and the floor. It can effectively protect against fractures. As a result, even if the adherend is an elderly person who develops osteoporosis or sarcopenia, the risk of fracture of the proximal femur can be sufficiently reduced (claim 3).

Air-guided hip fitness allows the wearer to switch on the controller of the air supply device in advance to the air-guided hip fitness when the wearer is judged to be at increased risk of falling. It is characterized by having a thigh protection portion that supplies air to the upper part of the thigh in the circumferential direction and presses the upper part of the thigh radially inward by expansion of the air-guided hip fitness. If the risk of falling is avoided, the wearer himself turns off the switch of the controller of the air supply device to exhaust the air of the air-guided hip fitness, and the air-guided hip fitness presses the tension on the upper thigh. It is characterized by a so-called dynamic supporter (claim 4).

Furthermore, the air-guided hip fitness pants stimulate the muscles of the upper thigh to stimulate muscle blood flow by equipping the air supply device with a mechanism that can intermittently set a mode that can be turned on and off. It is characterized in that it can be increased, and it is possible to impart a function of improving the pathological condition of degenerative diseases such as sarcopenia and osteoporosis and a relaxation effect by massage (claim 5).

According to this configuration, by having the above-mentioned plurality of cells, unlike the case where the thigh protection portion is composed of a single cell, for example, the pressing force applied from the thigh protection portion greatly fluctuates depending on the position on the thigh center line. It is possible to efficiently apply a pressing force due to the expansion of each cell to each part of the upper part of the thigh. In addition, the cell strength can be changed by adjusting the thickness and size of the cell structure, and the reinforcing action of the proximal femur due to muscle compression on the upper thigh can be exerted more efficiently in accordance with the anatomy of the living body. This can further reduce the risk of fracture of the proximal femur.

In the above configuration, more preferably, the thigh protection portion includes, as one of the plurality of cells, a specific cell that surrounds the vicinity of the base of the thigh portion of the adherend in the circumferential direction, and the specific cell is the above-mentioned specific cell. Along the base of the thigh, the legs are inclined so as to be located upward toward the outside in the body width direction (claim 6).

According to this configuration, by inflating in order from a specific cell, the muscle near the base of the thigh at a height corresponding to the proximal femur is pressed inward in the radial direction of the thigh. The muscles in the proximal part of the femur can be efficiently brought into close contact with each other.

In the above configuration, the thigh protection unit has a partition cloth for partitioning a plurality of cells including the specific cell from each other, and the partition cloth is a cell in which air supplied from the air supply device to the specific cell is used as another cell. A communication hole for introduction is formed in (Claim 7).

According to this configuration, the air first supplied to the specific cell can be introduced into another cell through the communication hole, and the plurality of cells can be reliably expanded. Further, the air in the cell whose internal pressure has increased due to the direct pressure at the time of falling can pressurize the other plurality of cells through the communication holes to dynamically protect the thigh protection portion in a ring shape.

According to this configuration, the air-guided hip-fitness pants further have a waist cell provided at a position covering the waist of the wearer, and the impact applied to the hip and buttocks of the wearer at the time of a fall is applied to the waist. It can be alleviated by the cell, and the risk of fracture of the pelvis or the like can be reduced (claim 8).

Preferably, the air-guided hip fitness has a flexion angle of 15 to 45 °, which is an anterior inclination angle of the thigh protection portion when the air-guided hip fitness is expanded, and the body width of the thigh protection portion. An angle regulating unit that regulates the bending angle and the abduction angle is further provided so that the abduction angle, which is the inclination angle to the outside in the direction, is 10 to 30 ° (claim 9).

According to this configuration, the posture of the lower body of the wearer is suitable for tensioning the muscles of the upper thigh when the wearer falls (when an impact is applied to the proximal part of the femur). Since the posture is controlled, more appropriate protection of the proximal femur can be achieved.

Preferably, the air-guided hip-fitness pants further include a relief valve that regulates the internal air pressure so that it does not exceed a predetermined upper limit when the air-guided hip-fitness pants are inflated. The pressure is set to any of 100-300 mmHg (Claim 10).

According to this configuration, a pressing force of 100 to 300 mmHg can be stably applied to the upper part of the thigh after the operation of the adherend. As a result, the muscles of the upper thigh of the wearer can be compressed with an appropriate pressure, and the stabilization and protective action of the proximal femur by the muscle reinforcement of the upper thigh can be enhanced.

Preferably, the pants body has an outer cloth portion and an inner cloth portion provided inside the outer cloth portion, and the air-guided hip fitness is provided between the outer cloth portion and the inner cloth portion (claim). 11).

Preferably, the air-guided hip fitness pants are provided with sizes such as S, M, and L according to the body shape of the wearer so that the wearer is appropriately pressurized during operation.

In this way, when the air-guided hip fitness is attached between the outer cloth part and the inner cloth part of the pants body, the air-guided hip is positioned at a position suitable for covering the upper part of the thigh of the wearer. -The fitness pants can be attached stably, and the above-mentioned effects of the air-guided hip fitness pants can be fully exerted. In addition, by adopting a fabric with excellent design as the outer fabric and a fabric that is soft to the touch as the inner fabric, the wearer feels resistance when wearing air-guided hip fitness pants. Can be significantly reduced, and air-guided hip fitness pants that are easy for the wearer to wear on a daily basis can be realized.

As described above, according to the air-guided hip-fitness pants of the present invention, the risk of fracture of the proximal femur during a fall can be sufficiently reduced.

FIG. 7 (a) is a diagram showing the skeleton of the lower body of the human body, and FIG. 7 (b) is an enlarged view of the proximal femur (the upper end of the femur near the pelvis). Of these, the broken lines Q1 and Q2 in FIG. 7A represent the bases of the left and right thighs. The base Q1 (Q2) of the thigh is the uppermost part of the thigh, specifically, the height corresponding to the hip joint (the joint between the pelvis and the femur), and is upward toward the outside in the body width direction. It is a part on a line that is inclined so as to be located. As can be understood from the comparison between FIG. 7A and FIG. 3 and the like, the boundary between the first and second cells 221,222 of the left thigh protection portion 22 is at the base Q1 of the left thigh portion. The right thigh protection portion 23 is formed so as to substantially coincide with each other, and the boundary between the first and second cells 231 and 232 thereof is formed so as to substantially coincide with the base Q2 of the right thigh portion.

In other words, in the air-guided hip fitness 2 of the present embodiment, the second cell 222, which is the second cell from the top in the left thigh protection portion 22, is circumferentially around the base Q1 of the left thigh and the vicinity thereof below. The second cell 232, which is the second cell from the top in the right thigh protection portion 23, is formed so as to surround the base Q2 of the right thigh and the vicinity thereof in the circumferential direction. These cells surrounding the vicinity of the bases Q1 and Q2 of the thigh, that is, the second cell 222 of the left thigh protection portion 22 and the second cell 232 of the right thigh protection portion 23 are the "specific cells" referred to in the claims. Corresponds to.

As shown in FIGS. 3 and 4, restraint cloths 30 made of a fabric having relatively low elasticity are attached to a plurality of positions of the left and right thigh protection portions 22 and 23. Specifically, in the present embodiment, the front surface and the outer side surface in the body width direction of the second to fourth cells 222 to 224 in the left thigh protection portion 22, and the second to fourth cells 232 to 234 in the right thigh protection portion 23. Restraint cloths 30 are attached to the front surface and the outer side surface in the body width direction, respectively. These restraint cloths 30 correspond to the "angle restricting portion" according to the claim, and play a role of regulating the shapes (angles) of the left and right thigh protection portions 22 and 23 when the air-guided hip fitness 2 is inflated. Fulfill. In FIGS. 3 and 4, for convenience, the restraint cloth 30 attached to the side surfaces of the left and right thigh protection portions 22 and 23 is represented by a thick alternate long and short dash line.

As shown in FIGS. 3, 4, and 6, the central base 21 of the air-guided hip fitness 2 has an upholstered portion 25 arranged so as to cover the abdomen and the pubic area of the wearer P, and the wearer. It has a waist cell 26 arranged so as to cover the waist portion of P.

The waist cell 26 is a bag body having a space inside which can receive the air supplied from the air supply device 3, and is the rear surface of the first cell 221 of the left thigh protection portion 22 and the first cell of the right thigh protection portion 23. It is arranged between the rear surface of 231 and the rear surface. Although not shown, the space inside the waist cell 26 is partitioned from the spaces X and Y in the left and right first cells 221,231 by a partition cloth, and the partition cloth is communicated to allow air to pass through. A hole is formed.

The upholstered portion 25 is in the form of a sheet that does not include a space inside. Therefore, even if air is supplied from the upholstered controller feeder 3, it does not expand. In addition, in FIG. 3 and FIG. 4, the upholstered portion 25 is colored in gray in order to distinguish the non-expanding upholstered portion 25 from other portions (cells).

Mainly as shown in FIG. 3, the air supply device 3 includes a controller 31, a left air pump 32 and a right air pump 33, and a cable 34 that electrically connects the left and right air pumps 32 and 33 and the controller 31. ing.

The controller 31 includes a switch 31a that the wearer himself / herself operates to turn on / off, and has a power source and a control circuit unit (both not shown) that output control signals to the left and right air pumps 32 and 33. The controller 31 is built in the belt portion 13 of the pants body 1. However, if it can be stored compactly, the air supply device and the air pump can be integrated.

The left air pump 32 and the right air pump 33 are air pumps that inflate the air-guided hip fitness 2. That is, when the wearable person P determines that the risk of falling increases, the air is supplied to the air-guided hip fitness 2 by turning on the switch, and each cell of the air-guided hip fitness 2 is 221 to 224, 231. ~ 234,26 expands.

The left air pump 32 is provided at a position where air can be directly supplied to the second cell 222 of the left thigh protection portion 22, and the right air pump 33 can directly supply air to the second cell 232 of the right thigh protection portion 23. It is provided in a suitable position. That is, mainly as shown in FIG. 6, the left air pump 32 has an outlet portion 32a communicating with the space X in the second cell 222, and the right air pump 33 is in the space Y in the second cell 232. It has an outlet portion 33a for communication. However, if it can be stored compactly, the air supply device and the air pump can be integrated.

By turning on the controller when the adherend P is at risk of falling, air is first supplied to the second cells 222 and 232 from the outlets 32a and 33a of the air pumps 32 and 33. The air supplied to the second cells 222 and 232 is introduced into other cells through the communication holes H1 and H2 formed in the partition cloths 226 and 236 that partition the cells (see the arrow in FIG. 6). As a result, air is introduced into all cells 221 to 224, 231 to 234, 26 of the air induction hip fitness 2, and each cell expands.

As shown in FIGS. 3 and 6, relief valves 41 and 42 are provided in the fourth cells 224 and 234 of the left thigh protection portion 22 and the right thigh protection portion 23, respectively. The relief valves 41 and 42 are preliminary valves that are opened so as to protect the hip joint portion so that the air pressure does not reach a predetermined upper limit pressure or higher, and each cell 221 to 224, when the inductive hip fitness 2 is expanded. It plays a role of regulating the air pressure in 231 to 234 and 26 from exceeding the above upper limit pressure. In the present embodiment, the upper limit pressure at which the relief valves 41 and 42 are opened is set to any of 100 to 300 mmHg. The relief valves 41 and 42 correspond to the "pressure regulation unit" referred to in the claims.

As described above, in the present embodiment, the left thigh protection portion 22 (right thigh protection portion 23) is constrained to the front surface of the second to fourth cells 222 to 224 (232 to 234) and the outer side surface in the body width direction, respectively. Cloth 30 (angle regulating part) is attached. Due to the action of the restraint cloth 30, in the air-guided hip fitness 2 of the present embodiment, as shown in FIGS. 8 and 9, the bending angles θ1 and the abduction angles θ2 of the left and right thigh protection portions 22 and 23 are respectively. It expands to fit within a predetermined angle range greater than 0 °. Here, the flexion angle θ1 is the forward inclination angle of the left and right thigh protection portions 22 and 23, and the abduction angle θ2 is the outward inclination of the left and right thigh protection portions 22 and 23 in the body width direction. It is the tilt angle. The flexion angle θ1 corresponds to the lateral crossing angle between the thigh center line L1 and the trunk axis L2 when the wearer tilts (flexes) the thigh forward with respect to the center of the hip joint. The abduction angle θ2 is the angle of intersection of the thigh center line L1 and the trunk axis L2 in front view when the wearer inclines (abduction) the thigh to the outside in the body width direction with respect to the center of the hip joint. It corresponds.

That is, in the present embodiment, the restraint cloth 30 having a relatively low elasticity is attached to the above-mentioned portion, so that the second to fourth cells 222 to 224 (232) of the left femur protection portion 22 (right femur protection portion 23) are attached. ~ 234), the rear surface is more easily stretched than the front surface, and the inner side surface is more easily stretched than the outer side surface in the body width direction. As a result, when the air-guided hip fitness 2 is inflated, the left femur protection portion 22 (right femur protection portion 23) naturally inflates while inclining forward and outward in the body width direction. The inclination angle at this time, that is, the bending angle θ1 and the abduction angle θ2 described above can be set by adjusting the degree of low elasticity of the restraint cloth 30. Specifically, in this embodiment, the bending angle θ1 is 15 to 45 ° (more preferably about 25 to 35 °), and the abduction angle θ2 is 10 to 30 ° (more preferably 10 to 15 °). The degree of low elasticity of the restraint cloth 30 is adjusted so as to be.

As described above, the air-guided hip-fitness pants of the present embodiment include the pants body 1 worn on the lower body of the wearer P and the air-guided hip-fitness 2 provided inside the pants body 1. , The wearer P is composed of an air supply device 3 that supplies air to the air-guided hip-fitness 2 to inflate the air-guided hip-fitness 2 in preparation for a fall, and the air-guided hip-fitness 2 is composed of the air-guided hip-fitness 2. Left thigh protection portion 22 and right thigh protection portion 23 (hereinafter, simply thigh protection portions 22, 23, etc.) that surround the left and right upper thighs of the wearer P in the circumferential direction and press the upper thigh inward in the radial direction when inflated. ). According to such a configuration, there is an advantage that the risk of fracture of the proximal femur when the adherend P falls can be sufficiently reduced.

That is, in the above embodiment, since the air-guided hip fitness 2 including the thigh protection portions 22 and 23 surrounding the upper part of the thigh of the wearer P in the circumferential direction is provided inside the pants body 1, the wearer P is provided. When the thigh protection portions 22 and 23 are inflated in preparation for a fall, the expansion force of the thigh protection portions 22 and 23 is mainly inside the pants body 1 (that is, the direction in which the wearer P is in close contact with the upper part of the thigh). The inflated thigh protection portions 22 and 23 press the upper part of the thigh of the adherend P with sufficient pressure inward in the radial direction. As a result, the muscles of the upper part of the thigh are in close contact with the femur, so that the proximal part of the femur (the upper end part of the femur), which is prone to fracture during a fall, can be effectively reinforced. Then, the synergistic effect of the reinforcing effect due to the close contact of the muscles and the buffering effect of the expanded femur protection portions 22 and 23 can effectively protect the proximal femur so as not to fracture.

For example, many older people develop sarcopenia, which reduces muscle mass with age, in addition to osteoporosis, which reduces bone density, and when such older people fall, the femur, especially the femur, There is an increased risk of fracture of the proximal femur near the pelvis. Fractures of the proximal femur often occur in the cervical and trochanteric regions shown in FIG. 7 (b). When such a fracture of the proximal femur occurs, long-term rehabilitation is unavoidable after undergoing major surgery, for example. Therefore, especially in the case of elderly people who develop osteoporosis and sarcopenia, the prognosis is self-help. It is not uncommon for the quality of life to deteriorate significantly, such as difficulty walking in the area.

On the other hand, according to the above embodiment in which the femur protection portions 22 and 23 of the air-guided hip fitness 2 surround the femur of the wearer P in the circumferential direction, there is a risk of the wearer P falling. When the wearer himself turns on the air-guided hip fitness switch and inflates it in advance, a pressing force acting radially inward from the femur protection portions 22 and 23 to the upper part of the femur causes the upper part of the femur. The muscles (for example, the hip muscle group such as the large hip muscle, the adductor muscle group such as the adductor muscle, and the flexor muscle group such as the femur bicep muscle) can be integrally attached to the femur from the surroundings. Moderate tension can be applied to the muscles of the upper femur. As a result, the proximal femur, which has a particularly high risk of fracture, is effectively reinforced, and the impact applied to the proximal femur is alleviated by the expanded femur protection portions 22, 23 (internal air thereof). Therefore, the proximal part of the femur can be effectively protected. In other words, in the above embodiment, since the thigh protection portions 22 and 23 of the air-guided hip fitness 2 act as so-called muscle substitutes, it is assumed that the adherend P is an elderly person who develops sarcopenia (that is, the thigh portion). Even in the elderly who have significantly reduced muscles), the risk of fracture of the proximal femur during a fall can be sufficiently reduced, and the quality of life of the elderly should be improved for a long period of time. Can be done.
As an example, wearing pajamas when sleeping, turning on the switch by yourself when moving the toilet such as at night or early morning, and filling the air-guided hip fitness with air compresses the proximal thigh. You can avoid accidental fall fractures as if sarcopenia was being avoided by moderate muscle tone. By turning off the switch after moving to the toilet, the air is exhausted, the air-guided hip-fitness pants are taken off and excreted, and after the toilet is finished, the air-guided hip-fitness pants are put on so that the pajamas can be worn again. The air-guided hip fitness is refilled with air, returned to the bed, and exhausted after arriving at the bed. This makes it possible to prevent a fracture in preparation for a fracture at the time of a fall by the same operation when moving a step such as a staircase.

Further, in the above embodiment, by providing the air supply device 3 with a mechanism capable of intermittently setting a mode capable of turning on and off, it is possible to stimulate the muscles of the upper thigh and increase muscle blood flow. It is possible to impart a pathological improvement function of degenerative diseases such as sarcopenia and osteoporosis and a relaxation effect by massage.

Further, in the above embodiment, the thigh protection portion 22 (23) includes a ring-shaped space X (Y) along the peripheral surface of the upper part of the thigh, and is divided into a plurality of cells 221 in the direction along the center line of the thigh. Since it has ~ 224 (231 to 234), for example, unlike the case where the thigh protection portion 22 (23) is composed of a single cell, the pressing force applied from the thigh protection portion 22 (23) is large depending on the position on the thigh center line. It is possible to avoid a situation such as fluctuation, and it is possible to efficiently apply a pressing force due to the expansion of each cell 221 to 224 (231 to 234) to each part of the upper part of the thigh. As a result, the muscles of the upper thigh can effectively reinforce the proximal femur, and the risk of fracture of the proximal femur can be further reduced.

Further, in the above embodiment, the plurality of cells 221 to 224 (231 to 234) of the thigh protection portion 22 (23) are located upward toward the outside in the body width direction along the base Q1 (Q2) of the thigh portion. Since it has a second cell 222 (232) that is inclined to and surrounds the vicinity of the base Q1 (Q2) in the circumferential direction, when the wearable person P switches on the air-guided hip-fitness, the second cell 222 (232) ) Expands, causing muscles near the base Q1 (Q2) of the thigh at a height corresponding to the proximal femur, specifically, base Q1 (Q2) and muscles located slightly below it. Is pressed radially medially to bring the muscle into close contact with the proximal femur. As a result, the proximal femur can be efficiently reinforced, and the impact on the proximal femur due to a fall can be sufficiently alleviated by the second cell 222 (232).

Further, in the above embodiment, the plurality of cells 221 to 224 (231 to 234) of the thigh protection portion 22 (23) are partitioned from each other by the partition cloth 226 (236), and each partition cloth 226 (236) has a communication hole. Since H1 (H2) is formed, the air first supplied from the air pump 32 (33) to the second cell 222 (232) can be introduced into another cell through the communication hole H1 (H2), which is common. The plurality of cells 221 to 224 (231 to 234) can be reliably expanded by using the air supplied from the air pump 32 (33) of the above. As a result, the number of air pumps 32 (33) can be reduced to simplify the structure, and a plurality of expanding cells 221 to 224 (231 to 234) can provide appropriate protection to the proximal femur.

Further, in the above embodiment, in addition to the thigh protection portions 22 and 23 covering the upper part of the thigh of the wearer P, a waist cell 26 covering the waist part of the wearer P is provided, so that the wearer when falling. The impact applied to the waist of P can be alleviated by the waist cell 26, and the risk of fracture of the pelvis, for example, can be reduced.

Further, in the above embodiment, when the air-guided hip fitness 2 is expanded, the bending angle θ1 (forward tilt angle) and the abduction angle θ2 (outward tilt angle in the body width direction) of the femur protection portion 22 (23). Since the restraint cloth 30 is attached to the thigh protection portion 22 (23) to regulate the distance between the two to 15 to 45 ° / 10 to 30 °, respectively, before the wearer P completely falls (proximal femur). Before the impact is applied to the part), the posture of the lower body of the wearer P can be controlled to be a posture suitable for tensioning the muscles of the upper part of the thigh. Appropriate protection can be achieved.

Further, in the above embodiment, since the relief valves 41 and 42 that are opened when the air pressure in the air-guided hip fitness 2 reaches 100 to 300 mmHg are provided in the air-guided hip fitness 2, the air immediately after expansion is provided. The air pressure in the induced hip fitness 2 can be maintained at 100 to 300 mmHg, and is 100 during the fall operation of the wearable person P (that is, from the time when the fall is detected until the wearer completely falls). A pressing force of ~ 300 mmHg can be stably applied to the upper part of the thigh. As a result, the muscles of the upper thigh of the wearer P can be appropriately tensioned, and the protective effect of the muscles of the upper thigh on the proximal femur can be enhanced.

Further, in the above embodiment, the pants body 1 has a double structure having an outer cloth portion 11 and an inner cloth portion 12, and an air-guided hip fitness 2 is provided between the outer cloth portion 11 and the inner cloth portion 12. Therefore, the air-guided hip-fitness 2 can be stably attached to a position suitable for covering the upper part of the thigh of the wearable person P, and the above-mentioned effect of the air-guided hip-fitness 2 can be fully exerted. Can be done. In addition, when the wearer P wears the air-guided hip fitness pants by adopting a fabric having excellent design as the outer cloth portion 11 and using a soft fabric as the inner cloth portion 12. The feeling of resistance can be significantly reduced, and the wearer P can wear it on a daily basis to realize air-guided hip fitness pants.

In the above embodiment, a total of two air pumps 32 and 33 that supply air to the left and right thigh protection portions 22 and 23 are attached to the air induction hip fitness 2, but the number of air pumps is appropriately changed. It is possible. For example, a single air pump that supplies air to the entire air-guided hip fitness 2 may be provided, or three or more air pumps may be provided. Further, the controller and the air pump may be unitized and built into the belt-shaped exterior component, and then the exterior component may be detachably attached around the waist.

In the above embodiment, the gender of the wearer P who wears the air-guided hip fitness pants is not particularly mentioned, but the air-guided hip fitness pants are made according to the gender of the wearer P. You may. For example, if the structure of the air-guided hip fitness pants for men / women is the same, the genital area may be excessively compressed when the wearer is a man. Therefore, for men's air-guided hip fitness pants, it is desirable to take measures to prevent excessive pressure on the genital area. For example, a relatively hard fabric for suppressing the amount of expansion in the direction toward the genital area is attached to the cell of the air-guided hip fitness pants closest to the genital area (first cells 221,231 in the above embodiment). It is good to take measures such as.

In the above embodiment, only the air-guided hip fitness 2 is prepared as the air-guided hip fitness pants provided inside the pants body 1, but the air-guided hip fitness 2 is different from the air-guided hip fitness 2. Additional fitness pants may be provided. For example, it is conceivable to provide additional air-guided hip-fitness pants made of an integral bag-like body that surrounds the air-guided hip-fitness 2 substantially from the entire circumference of the air-guided hip-fitness 2. When such additional air-guided hip fitness pants are provided, the impact applied to the proximal femur during a fall is significantly reduced, and there is a risk of fracture of the proximal femur during a fall. Is expected to be further reduced.

In the above embodiment, the pants body 1 has a double structure having an outer cloth portion 11 and an inner cloth portion 12, but as long as the air-guided hip fitness 2 can be attached to the inside of the pants body 1, the pants body 1 has a double structure. The structure of the pants body 1 can be changed as appropriate. For example, the air-guided hip fitness may be attached to the inner surface of the (single-layered) pants body without the inner cloth portion so that the air-guided hip fitness pants are in direct contact with the wearer's body. ..

In the above embodiment, short pants type clothing that covers the waist of the wearer P and the upper left and right thighs is used as the pants body 1, but the present invention is not limited to this, and the short pants type that extends to the wearer's knees. Or long pants-type clothing that covers the wearer's legs as a whole may be used as the pants body.

Further, as the pants body, for example, those having an uneven appearance corresponding to the shape of the cells of the air-guided hip fitness pants as shown in FIGS. 10 and 11 may be adopted. FIG. 10 shows an example in which a pants body having such a shape (so to speak, a down coat style) is applied to women, and FIG. 11 shows an example in which this is applied to men. In each figure, 1'(1 ") indicates the pants body, and 3'(3") indicates the air supply device. Air-guided hip fitness pants are provided inside the pants body 1'(1 "), and these air-guided hip fitness pants supply air at least in a position corresponding to the upper part of the thigh of the wearer. It has a plurality of ring-shaped cells that expand by receiving the supply of air from the device 3'(3 "). These plurality of ring-shaped cells are attached in association with the uneven shape of the pants body 1'(1 ").
