  In the first aspect described below, a part including a leg knee joint is applied as a joint part, and the body support device according to the first aspect is attached to a part including the leg knee joint as a joint part. Is done.

In the present specification, in the knee joint portion of the leg, the patella side of the leg may be referred to as “front surface” or “front surface”, and the side of the leg popliteal portion (so-called knee back) may be referred to as “back surface” or “rear surface”. There is. The front surface and the front surface refer to the side opposite to the bending side (extension side) in the knee joint, and the back surface and the rear surface refer to the bending side in the knee joint.
Further, in the present specification, a surface between the front (or front) and back (or rear) surfaces of the legs may be referred to as “side surface”. Further, in the present specification, the hip joint side as viewed from the patella is referred to as “upper side”, and the heel side as viewed from the patella is referred to as “lower side”.

  The stay 10 as a body support tool according to the first aspect includes a long and bag-like stay main body 12 as a support, and the stay main body 12 has flexibility. FIG. 1 is a front view of the stay main body 12 as viewed from the side opposite to the joint part, and FIG. 2 shows the stay main body 12 cut in a direction intersecting the longitudinal direction at the middle portion in the longitudinal direction. It is shown in a sectional view. In the drawing, in the stay main body 12 maintaining a straight shape, the longitudinal direction (length direction) is indicated by an arrow Z, the width direction is indicated by an arrow X, and the height direction is indicated by an arrow Y. ing.

  The stay body 12 has one side in the height direction on the joint part side (the opposite side to the arrow Y direction), and the longitudinal direction corresponds to the direction intersecting the circumferential direction of the joint part. Used at the knee joint.

  As shown in FIG. 2, a long accommodating portion 14 as a hollow portion is formed inside the stay main body 12, and the accommodating portion 14 is continuous over the entire area in the longitudinal direction of the stay main body 12. ing. In the accommodating part 14, the granular material 16 as a solid particle is accommodated, and the granular material 16 is accommodated in the accommodating part 14 and enclosed with the stay main body 12. FIG. In the stay body 12, the powder body 16 is accommodated in the accommodating portion 14, so that the outer shape expands in a substantially rod shape. The granular material 16 is filled in at least the knee 24 portion in the accommodating portion 14, and the granular material 16 can flow in the accommodating portion 14.

  In the stay body 12, the internal shape (the shape of the inner peripheral surface of the accommodating portion 14) changes due to deformation such as bending. The granular material 16 in the stay main body 12 is pushed and fluidized by the stay main body 12 when the stay main body 12 is bent. Further, when the stay main body 12 tries to bend, if the granular material 16 does not flow, the stay main body 12 is prevented from being bent. For this reason, when the granular material 16 flows, the stay main body 12 is bent, and the stay main body 12 is bent or stretched by being bent or returned to the bent state. Further, the stay main body 12 is restrained from being bent when the flow of the granular material 16 is suppressed in the accommodating portion 14.

  Although there is no restriction | limiting in the particle diameter of the granular material 16 accommodated in the stay main body 12, It is preferable that the particle diameter of the granular material 16 is 10 micrometers or more and 3 mm or less. That is, at least one aggregate of a powder (coarse powder) having a particle diameter of 10 μm or more and less than 1 mm and a particle having a particle diameter of 1 mm or more and 3 mm or less is applied to the powder body 16.

  In the granular material 16, the smaller the particle diameter, the lower the fluidity. However, the granular material 16 is fluid in a state of being accommodated in the accommodating portion 14 because the particle diameter of the granular material 16 is 10 μm or more. Is obtained. It is possible to prevent the user wearing the stay body 12 from feeling hard because the powder particles 16 have fluidity.

  Moreover, in the granular material 16, when it accommodates in the stay main body 12 because a particle diameter becomes large, it becomes easy to produce an unevenness | corrugation on the surface of the stay main body 12. FIG. The unevenness on the surface of the stay main body 12 tends to give the user a bumpy feeling, a rough feeling, or a biting feeling (a feeling that the user bites into the skin). By setting the particle diameter of the powder body 16 to 3 mm or less, it is possible to suppress the occurrence of a bumpy feeling, a rough feeling, and a biting feeling for the user wearing the stay main body 12.

  The material of the powder body 16 is not limited as long as it is a solid material, and the powder body 16 may be sand, ceramics, a polymer compound, or a metal. The polymer compound may be a non-elastic body of a synthetic resin (plastic or the like) or an elastic body such as rubber (natural rubber) or synthetic rubber. Further, gel particles may be used for the granular material 16.

  The powder body 16 may be a solid body having no hollow portion inside, or may be a hollow body or a porous body having a hollow portion inside. The granular material 16 imparts a predetermined weight to the stay main body 12, so that the user who wears the stay main body 12 can be given a sense of support by the stay main body 12. Further, by using a hollow body or a porous body as the powder body 16, the stay body 12 in which the powder body 16 is enclosed can be reduced in weight, and the user feels that the stay body 12 is heavy. Can be suppressed.

  Further, since the powder body 16 is a hollow body or a porous body, each particle becomes light and easily flows, so that the powder body 16 has a similar friction coefficient, so that the hollow body or the porous body can be used. By being a body, fluidity is higher than that of a solid body.

  The fluidity of the powder particles 16 in the stay main body 12 is influenced by the material of the powder particles 16, the particle size as an index of the shape, whether it is solid or porous, and the friction coefficient. In addition, the fluidity of the powder particles 16 is affected by the particle diameter, and the dispersion of the particle diameters.

  As an index of the particle size distribution, which is a variation in particle size, the uniformity K of particle size can be applied. Uniformity K is also used as an index indicating aggregability, and the ratio of the particle diameter D2 corresponding to 60% by weight to the particle diameter D1 corresponding to 10% by weight (K) as seen from the smaller particle diameter (K = D2 / D1). The degree of uniformity K is calculated from the particle diameters D1 and D2 obtained by obtaining a particle diameter D1 of 10% under the sieve and a particle diameter D2 of 60% under the sieve by the particle size distribution measured by particle size distribution measurement or sieving. .

  In the stay 10, it is preferable that the granular material 16 has a particle size uniformity K of 1.2 or more and 6 or less (K = 1.2 to 6).

  In the powder 16, when the difference in particle diameter is large, particles (powder) having a small particle diameter enter between particles (particles) having a large particle diameter, and particles having a small particle diameter are particles having a large particle diameter. The cohesiveness is increased by regulating the movement of the. The granular material 16 becomes more cohesive as the uniformity K becomes larger (away from 1), and as the uniformity K approaches 1, the range of the particle diameter becomes narrower and it becomes difficult to agglomerate.

  For this reason, in the stay 10, when the uniformity K of the granular material 16 is less than 1.2, the movement of the particles becomes difficult to be regulated (it is difficult to aggregate), and thus a stable support feeling cannot be obtained. Moreover, in the stay 10, when the uniformity K of the granular material 16 exceeds 6, the movement of the particles becomes easy to be regulated, and the stay main body 12 becomes difficult to bend (becomes difficult to bend).

  In the granular material 16, when the uniformity K is low, the porosity of the granular material 16 depends on the particle diameter (average particle diameter) of the granular material 16. The average particle diameter of the granular material 16 is obtained by collecting 10 particles from the granular material 16 and calculating the diameter of each of the collected particles (the average value of the short diameter and long diameter of the particles if the particles are not substantially spherical). Measured with an optical microscope, and the average value obtained is used. As the particle diameter 16 increases, the gap between the particles increases and the space ratio increases. Moreover, in the granular material 16, when the degree of uniformity K is high, particles having a small particle diameter enter between particles having a large particle diameter, so that the space ratio of the granular material 16 is lowered.

  Further, when the granular material 16 is accommodated in the accommodating portion 14, if the amount of the granular material 16 (total volume excluding the space portion between the particles) is small with respect to the volume of the accommodating portion 14, the stay body 12 stabilizes. You will not be able to get a feeling of support. Further, if the amount of the granular material 16 becomes too large with respect to the volume of the accommodating portion 14, the stay main body 12 is excessively swollen or the granular material 16 is tightened by the stay main body 12. The fluidity decreases and the user feels hard.

  From here, in the accommodating part 14 of the stay main body 12, the granular material 16 is filled to the knee 24 part at least, and the volume fraction made into the ratio which the granular material 16 occupies in the accommodating part 14 is 30 vol%. The above is necessary and is preferably 40 vol% or more. Moreover, it is more preferable that the volume fraction of the granular material 16 is 50 vol% or more, Most preferably, it is 60 vol% or more.

  Further, if the volume fraction is too large, the movement of individual particles is suppressed, and the fluidity of the powder granules 16 is reduced. Therefore, the volume fraction of the powder granules 16 is preferably 98 vol% or less. More preferably, it is 95 vol% or less. In the stay main body 12, for example, the space portion 50 of the granular material 16 and the volume fraction vol 50% of the granular material 16, so that the accommodating portion 14 is between the particles in the granular material 16 and the granular material 16. The space is filled (the filling rate is approximately 100%), and the fluidity is suppressed. From here, the granular material 16 is enclosed with the stay main body 12 so that a filling rate may not reach 100%.

  Therefore, the fluidity of the powder particles 16 affects the material, particle size, solid or porous material, friction coefficient, and uniformity K (variation of particle diameter) of the powder particles 16, It also affects the space factor and volume fraction. In the stay 10, the fluidity of the powder particles 16 affects the flexibility of the stay main body 12.

  From this, the powder body 16 is adjusted in material, particle size, solid or porous body, friction coefficient, uniformity K (variation in particle diameter), spatial rate, and volume fraction. This adjusts the liquidity. In the stay 10, a powder body 16 that is adjusted so as to obtain desired flexibility is used for the stay main body 12.

  On the other hand, the stay body 12 is formed so as to obtain flexibility by using a sheet-like material (raw material). The stay body 12 is made of a material that can be stretched to such an extent that wrinkles do not occur when bent.

  There is no restriction | limiting in the sheet-like material used for the stay main body 12, The material used for the stay main body 12 may be a resin film, and may be a cloth (woven fabric) or a knitted fabric (knitted fabric). Since the powder body 16 is accommodated in the stay main body 12, the material of the stay main body 12 is a cloth or knitting that is thicker than the resin film when obtaining the same flexibility (softness). It is preferable to use a product. Further, by using the cloth or the knitted fabric, a good contact feeling can be given to the user by the woven structure of the cloth or the knitted structure of the knitted fabric.

  When a fabric or a knitted fabric is used for the stay main body 12, there is no limitation on the woven structure of the fabric and the knitted structure of the knitted fabric, but the size (opening) of the weave and the stitch is smaller than the particle diameter of the granular material 16. The size of the weave and the stitch may be any size as long as the powder body 16 does not come out. When a fabric or knitted fabric is used for the stay body 12, the material of the woven yarn or the knitting yarn is not limited, and the woven yarn or the knitting yarn may be any of natural fiber and synthetic fiber, and a plurality of different plural A fiber material may be mixed.

  Although there is no restriction | limiting in the external shape of the stay main body 12, As for the external shape of the stay main body 12, it is preferable that the surface at the side of a user is a substantially planar shape. The stay main body 12 can give a stable support feeling to the user because the surface of the joint part side of the user is substantially flat.

  In the outer shape of the stay main body 12, the cross-sectional shape in the direction intersecting the longitudinal direction may be a polygonal shape such as a triangular shape or a quadrangular shape, and a shape obtained by dividing the spindle shape in half in the axial direction (substantially semi-spindle shape) It may be a substantially semicircular shape such as a shape.

  Moreover, there is no restriction | limiting in the inner surface shape of the accommodating part 14 in the stay main body 12, The inner surface shape of the accommodating part 14 may be the same (substantially similar shape) as the external shape of the stay main body 12, and may differ. . For example, in the stay main body 12 having a quadrangular outer cross section, the inner shape of the accommodating portion 14 may be a polygonal shape such as a triangular shape or a quadrangular shape, such as a spindle shape divided in half in the axial direction or a kamaboko shape. A substantially semicircular shape or a shape including irregularities such as a star-shaped polygonal shape may be used.

  As shown in FIG. 2, the stay main body 12 has a cross-sectional outer shape and a cross-sectional inner diameter (inner surface shape of the accommodating portion 14) that are substantially semicircular (kamaboko-shaped). In the stay main body 12, the user's joint part side (direction opposite to the arrow Y direction) is a side part 18 as a flat part, and the side part 18 has a joint part side surface (outer surface) The stay body 12 has a substantially planar shape that is long in the longitudinal direction.

  The stay main body 12 has a peripheral surface portion 20 on the side opposite to the side surface portion 18, and the peripheral surface portion 20 is a portion directed in the height direction of the stay main body 12 from both ends in the width direction of the side surface portion 18. And a portion connecting both ends in the height direction. The peripheral surface portion 20 constitutes a portion that does not contact the body, and the peripheral surface portion 20 has a substantially arc-shaped cross section in a direction intersecting the longitudinal direction. When the stay main body 12 is attached to the joint site, the side surface 18 is curved along the surface of the joint site.

  In the stay main body 12, it is preferable that the thickness and softness of the peripheral surface portion 20 are the same as the thickness and softness of the side surface portion 18 or are thinned and softened by the side surface portion 18. Thereby, in the stay main body 12, when a user wears, the unevenness | corrugation by the granular material 16 can be suppressed on the surface by the side of the joint part of the side part 18, and a bumpy feeling, a rough feeling, or a biting feeling to a user can be suppressed. Can be suppressed.

  The length of the stay body 12 in the longitudinal direction (Z direction) is the length L, the dimension of the stay body 12 in the width direction (X direction) (particularly the dimension of the side surface portion 18) is the width W, and the thickness direction of the stay body 12 ( When the dimension in the Y direction is set to the height H, the length L, the width W, and the height H of the stay main body 12 are not limited, but are preferably at least in the following ranges. The length L, the width W, and the height H of the stay main body 12 are more preferably matched to the joint site (the user's body) to which the stay main body 12 is attached.

The length L of the stay body 12 is preferably 30 mm (3 cm) or more and 1000 mm (100 cm) or less (30 mm ≦ L ≦ 1000 mm).
If the length L of the stay main body 12 is less than 30 mm, the stay main body 12 is too short, and it becomes difficult to assist bending and extension of the joint part. When the length L of the stay main body 12 exceeds 1000 mm, the stay main body 12 is too long for the body as well as the joint part.

The width W of the stay body 12 is preferably 2 mm or more and 50 mm (5 cm) or less (2 mm ≦ W ≦ 50 mm).
When the width W of the stay main body 12 is less than 2 mm, not only can the user not be given a stable support feeling, but also the user can feel that the stay main body 12 is pulling the skin. . Further, if the width W of the stay main body 12 exceeds 50 mm, it will be felt that the skin will be pulled when the joint part is moved, and it will be easy for the user to feel a tension (twitching feeling).

The height H of the stay body 12 is preferably 1 mm or more and 20 mm (2 cm) or less (1 mm ≦ H ≦ 20 mm).
When the height H of the stay main body 12 is less than 1 mm, the movement of the powder body 16 having a relatively large particle diameter is likely to be hindered, and irregularities are likely to appear on the surface of the side surface portion 18. Further, if the height H of the stay main body 12 exceeds 20 mm, the user's clothes are bulged and the appearance is impaired. Further, if the height H of the stay main body 12 exceeds 20 mm, the stay main body 12 protrudes from the user's body, causing the user to feel that the stay main body 12 is hanging, which is not preferable.

Next, attachment of the stay 10 of the first aspect to the joint site will be described.
In the first aspect, the stay 10 is applied with the knee 24 (the knee joint) of the leg 22 as a joint part, and the stay main body 12 is attached to the knee 24 portion. FIG. 3 shows a state in which the stay main body 12 is attached to the knee 24 of the leg 22.

  The side surface 18 of the stay main body 12 is directed toward the leg 22, and the intermediate portion in the longitudinal direction is disposed on the side of the knee 24. Further, the upper side (one end side in the longitudinal direction) of the stay main body 12 is disposed on the side surface of the thigh 26 (the thigh 26 side of the knee 24) of the leg 22, and the lower side (the other end side in the longitudinal direction) of the stay main body 12. Is arranged on the side surface of the shin 28 of the leg 22 (the shin 28 side of the knee 24). Thereby, the stay main body 12 is arrange | positioned ranging from the thigh 26 side of the knee 24 to the shin 28 side.

  The stay 10 is used with the stay main body 12 disposed on at least one of the inside and the outside of the leg 22. The stay body 12 is preferably arranged along the motion axis of the knee 24 in the leg 22. The stay main body 12 may be attached to the front side of the knee 24. In this case, the stay main body 12 is attached to the surface opposite to the bending direction of the knee 24, so that the stay main body 12 is formed to be stretchable in the longitudinal direction. It is preferable that

  The length L of the stay main body 12 attached to the leg 22 (the knee 24 portion) is a viewpoint for assisting the quadriceps muscle, the patella ligament, the anterior cruciate ligament, etc. that connect the femur and the rib at the knee joint portion. To 80 mm or more (L ≧ 80 mm). Further, the length L of the stay body 12 is preferably long, but if it is longer than necessary, both end sides of the stay body 12 cause unnecessary contact feeling on the thigh 26 side and the shin 28 side. The length L of the stay main body 12 is preferably 400 mm or less (L ≦ 400 mm).

  The mounting means for mounting the stay main body 12 of the stay 10 to the joint part can be mounted in a state in which the movement of the stay main body 12 with respect to the joint part is suppressed, and the stay main body 12 receives force according to the bending and stretching operation of the joint part. So long as it can be mounted.

As the attaching means, a double-sided tape as an attaching means and an adhering means may be used, and the surface of the side surface portion 18 of the stay main body 12 may be attached to the joint site by the double-sided tape.
Moreover, as a mounting means, you may use the hook_and_loop | surface fastener provided with the hook part raised in hook shape, and the loop part (pile part) densely raised in loop shape. When using a hook-and-loop fastener, one of the hook portion and the loop portion is provided on the side surface portion 18 of the stay main body 12, the other of the hook portion and the loop portion is provided at the joint portion, and the hook portion and the loop portion are brought into surface contact. By engaging, the stay main body 12 is attached to the joint site.

  In the first aspect, the taping tape 30 as the mounting means and the tape is used. The taping tape 30 may be a stretchable tape or a non-stretchable tape. The taping tape 30 has one surface that is adhesive, and the taping tape 30 has the adhesive surface directed toward the body and spans the range of the knee 24 from the thigh 26 side to the shin 28 side. And is wound around the leg 22 and attached. As a result, the taping tape 30 supports the knee 24 (knee joint) portion of the leg 22. At this time, the taping tape 30 is wound around the leg 22 in a state where the stay main body 12 is disposed on the knee 24 portion of the leg 22. Accordingly, the stay main body 12 is mounted in a state in which the stay main body 12 is in close contact with the leg 22 and the relative movement with respect to the leg 22 is restricted.

  The stay main body 12 is attached to the knee 24 portion, so that when the knee 24 is bent and stretched (bent and extended), a force (bending force) is applied in the bending and extending direction, and the powder body 16 is responded to this force. Is bent and stretched (bends) in accordance with the bending and stretching operation of the knee 24.

  By the way, a person who has a disorder in the knee 24 part (a knee joint part) or a person who is rehabilitating a past disorder in the knee 24 part feels unstable in the knee joint part or bends and stretches the knee 24 (bending and bending). I feel anxious about (extension). When anxiety is felt in the bending / extending movement of the knee 24, it is desired that the knee 24 be gently bent and stretched, so that the knee 24 is supported to follow the bending / extending / extension of the knee 24. Is desired.

  In the stay main body 12, the granular material 16 is enclosed in the accommodating part 14 so that a flow is possible, and when the knee 24 is extended, the stay main body 12 becomes substantially linear. The user feels that the side surface portion 18 of the stay main body 12 is in surface contact so that the surface of the side surface portion 18 is a support surface, and the knee 24 is supported by the side surface portion 18 of the stay main body 12.

  Further, when the stay main body 12 is bent or the bent stay main body 12 is extended, the granular material 16 is pressed (pressed) and flows in the accommodating portion 14. For this reason, when the stay main body 12 is bent and stretched, a resistance against a force for causing the powder particles 16 in the stay main body 12 to flow is generated in the stay main body 12, and this resistance becomes a load on the knee 24.

  As a result, the user feels that the knee 24 is supported by the stay body 12 when the knee 24 is bent and extended, so that the user feels that the knee 24 is supported by the stay body 12. There is a sense of security in bending and stretching.

  Here, the fluidity of the powder particles 16 varies depending on the pressing force applied to the powder particles 16. When the knee 24 bends and stretches slowly, the powder particles 16 flow according to the knee 24 bends and stretches. For this reason, the stay main body 12 is bent and stretched according to the bending and stretching operation of the knee 24. Thus, when the knee 24 is gently bent and extended, the user feels that the knee 24 is bent and extended by being supported by the stay body 12, and the gentle bending and extending movement of the knee 24 is assisted by the stay body 12. I feel that

  On the other hand, when the knee 24 is suddenly bent and extended, the granular material 16 flows while being compressed in the stay main body 12. At this time, in the granular material 16, particles having a relatively small particle diameter are pushed between particles having a relatively large particle diameter, and movement (flow) of each other is suppressed. For this reason, in the stay main body 12, the fluidity of the powder particles 16 is lowered, the resistance against the bending / extending operation of the knee 24 is increased, and the stay main body 12 suppresses the rapid bending / extending operation of the knee 24. Moreover, since the drag force against the bending and stretching of the stay body 12 is generated by the pressing force, the stay body 12 can suppress the sudden bending and stretching action of the knee 24 without delay.

  Thereby, when the user tries to bend and extend the knee 24 suddenly, the stay main body 12 suppresses the bending and stretching operation of the knee 24, so that the user feels uneasy about the sudden bending and stretching of the knee 24. Can be suppressed. Further, since the stay main body 12 can suppress the knee 24 from being bent suddenly even though the user tries to bend the knee 24 gently, the stay main body 12 is used for the bending / extending operation of the knee 24. Can give people a sense of security.

  Therefore, the stay main body 12 can support the knee 24 with respect to the gentle bending / extending movement of the knee 24 and can suppress the bending / extending movement of the knee 24 with respect to the sudden bending / extending movement of the knee 24. The knee 24 can bend and extend.

  Such bending and stretching of the stay body 12 is obtained by the fluidity of the powder particles 16 in the stay body 12. In addition, the fluidity of the granular material 16 includes the material of the granular material 16, the particle size, whether it is solid or porous, friction coefficient, uniformity K (variation of particle diameter), spatial rate, and volume fraction. It affects the rate and can be adjusted by a combination of these.

  Thereby, the powder body 16 adjusted so that fluidity according to the state of the knee 24 and the degree of anxiety of the user's knee 24 can be obtained is enclosed in the stay body 12, so that the knee 24 can bend and extend. Appropriate assistance is possible. Further, by using the stay main body 12 in which the granular material 16 whose fluidity is adjusted according to the state of the disorder of the knee 24 and the change of the state is used, the operation according to the state of the disorder of the knee 24 and the change of the state Assistance is possible.

For example, by using the granular material 16 adjusted so that the fluidity is lowered, the bending / extending operation of the knee 24 can be suppressed, so that the anxiety about the bending / extending operation of the knee 24 can be eliminated. In this case, as the anxiety about the bending and stretching of the knee 24 decreases, the fluidity of the granular material 16 is increased, so that proper operation assistance corresponding to the state change of the knee 24 can be performed.
Moreover, it can apply to the rehabilitation for strengthening the bending / stretching force of the knee 24 by using the granular material 16 adjusted so that the fluidity is low and feels heavy.
In the first aspect, the stay main body 12 is disposed on the body side (the leg 22 side) of the taping tape 30, but the stay main body 12 is attached to the opposite side of the taping tape 30 from the body by an adhesive means or the like. May be attached.

[Modification of the first aspect]
In the body support tool according to the first aspect, the support may be formed with a widened portion in which the flat portion is widened in a direction intersecting the longitudinal direction at an intermediate portion in the longitudinal direction. A plurality of widened portions may be formed in a bellows shape arranged in the longitudinal direction.
In addition, the support body may be branched into a plurality in a direction that intersects the longitudinal direction at the intermediate portion in the longitudinal direction and is along the surface of the joint part.

FIG. 4A shows a stay 32 as a body support tool according to a modification of the first aspect in a front view.
As shown in FIG. 4A, the stay 32 includes a long and bag-like stay main body 34 as a support, and a housing portion 36 as a hollow portion is formed inside the stay main body 34. ing. In the stay main body 34, the powder particles 16 are accommodated in the accommodating portion 36, and the powder particles 16 are made flowable and enclosed in the stay main body 34.

  The stay main body 34 is formed with a widened portion 38 at an intermediate portion in the longitudinal direction, and the widened portion 38 is curved in a substantially arc shape so as to be convex toward both sides in the width direction of the stay main body 34. Yes. In addition, the space of the accommodating portion 36 is widened in the widened portion 38. Thereby, the area of the body side surface of the stay main body 34 (area per unit length in the longitudinal direction) is widened at the widened portion 38 more than both ends in the longitudinal direction, and the support surface is widened at the middle portion in the longitudinal direction. ing.

  The stay 32 is mounted on the leg 22 with the widened portion 38 of the stay main body 34 facing the knee 24 (joint portion) (not shown). For this reason, as for the stay 32, the support surface of the intermediate part of a longitudinal direction is expanded compared with the both ends of a longitudinal direction, and the wide support surface is opposed to the knee 24. FIG. Thereby, the user wearing the stay main body 34 of the stay 32 feels that the knee 24 is supported in a wide range, and the sense of security with respect to the bending / extending operation of the knee 24 is improved.

FIG. 4B shows a stay 40 as a body support tool according to another modification of the first mode in a front view.
As shown in FIG. 4B, the stay 40 includes a long and bag-like stay main body 42 as a support, and a housing portion 44 as a hollow portion is formed inside the stay main body 42. Has been. In the stay main body 42, the granular material 16 with adjusted fluidity is accommodated in the accommodating portion 44, and the granular material 16 is sealed in the stay main body 42 so as to be flowable.

  Here, a plurality of (for example, three) branch portions 46 each formed in a cylindrical shape are provided in the intermediate portion in the longitudinal direction of the stay main body 50, and the plurality of branch portions 46 are formed on the stay main body 42. Are arranged in the width direction. The longitudinal end of the branching portion 46 is connected to the longitudinal end of the stay main body 42, and the inside of the branching portion 46 is communicated with both longitudinal ends of the stay main body 42. Accordingly, the accommodating portion 44 is branched into a plurality at the middle portion in the longitudinal direction of the stay main body 42.

  The stay 40 is attached to the leg 22 with the branch portion 46 of the stay main body 42 facing the knee 24 (joint portion) (not shown). For this reason, the user feels that the space between the plurality of branch portions 46 is a pseudo support surface, and thus feels that the knee 24 portion is stably supported in a wide range. Moreover, the granular material 16 is enclosed by the stay main body 42 so that a flow is possible, and each branch part 46 bends individually by the granular material 16 flowing. For this reason, the stay body 42 can assist the knee 24 in bending and extending.

FIG. 5 is a perspective view showing a stay 48 as a body support tool according to another modification of the first mode.
As shown in FIG. 5, the stay 48 includes a long and bag-like stay main body 50 as a support, and an accommodation portion 52 as a hollow portion is formed inside the stay main body 50. In the stay main body 50, the granular material 16 is accommodated in the accommodating portion 52, and the granular material 16 is made flowable and enclosed in the stay main body 50.

  Here, a plurality of widened portions 54 are provided at an intermediate portion in the longitudinal direction of the stay main body 50, and the widened portions 54 are arranged in the longitudinal direction of the stay main body 50. The widened portion 54 protrudes in a substantially triangular shape on both sides in the width direction, and protrudes in a substantially semi-spindle shape in the height direction (arrow Y direction). As for the accommodating part 52 of the stay main body 50, internal space is expanded in the width direction and the height direction in each of the wide part 54. FIG. Further, in the stay main body 50, a constricted portion 56 is formed between the widened portions 54 adjacent to each other in the longitudinal direction, and the stay main body 50 has a middle portion in the longitudinal direction formed in a substantially bellows shape.

  The stay 48 is attached to the leg 22 (not shown) with the widened portion 54 of the stay main body 50 facing the knee 24 (joint portion). For this reason, since the user feels that the space between the plurality of widened portions 54 is a pseudo support surface, the user feels that the knee 24 portion is stably supported in a wide range. In addition, since the powder body 16 is encapsulated in the stay main body 50 so as to be flowable, the stay main body 50 can assist the bending and stretching operation of the knee 24.

Further, in the stay main body 50, the constricted portion 56 is formed between the widened portions 54. Therefore, even if the area facing the body (eg, the leg 22) in the widened portion 54 is widened, the constricted portion 56 is easy. The knee 24 can be flexed and extended appropriately.
The plurality of widened portions 54 are provided in the intermediate portion in the longitudinal direction of the stay main body 50, but the widened portions 54 may be formed over the entire region in the longitudinal direction.

[Second embodiment]
The body support device includes the following configuration.
A mounting means for mounting a long support disposed over the joint part so as to be able to bend according to the bending and stretching of the joint part, and a long intermediate part formed in the support body, A body support device comprising: a hollow portion opposed to the joint portion; and solid particles filled and accommodated in the support body until at least the joint portion is reached in the hollow portion.
The hollow part of the support body is a body support tool formed by arranging a plurality of compartments separated from each other by a partition wall.

Moreover, the body support tool may include the following configurations.
The plurality of compartments are body supports arranged in a vertical direction and a direction intersecting the vertical direction in a state where the support body is attached to the body.

  The stay 60 as the body support tool according to the second aspect includes a stay main body 62 as the support body. 6A shows a main part of the stay main body 62 in a sectional view in front view, and FIG. 6B shows a main part of the stay main body 62 in a sectional view in width direction. It is shown.

  The stay main body 62 is formed in a long and substantially bag shape, and an accommodating portion 64 as a hollow portion is formed inside the stay main body 62. In the stay main body 62, the granular material 16 whose fluidity is adjusted is accommodated in the accommodating portion 64, and the granular material 16 is enclosed in the stay main body 62 so as to be flowable.

  In the second aspect, the basic configuration of the stay main body 62 is the same as that of the stay main body 12 in the first aspect, but the accommodation portion 64 of the stay main body 62 is different from the accommodation portion 14 of the stay main body 12. .

A plurality of small chambers 66 as compartments are provided in the stay main body 62, and the accommodating portion 64 is formed by arranging a plurality of small chambers 66.
The sectional shape of the small chamber 66 is not limited, and the sectional shape of the small chamber 66 may be a polygonal shape such as a triangular shape or a quadrangular shape when viewed from the front, or a non-angular shape such as a semicircular shape or a semielliptical diameter. Also good. The internal space (three-dimensional space) of the small chamber 66 is determined by the cross-sectional shape, but may be a pyramid shape such as a triangular pyramid shape or a quadrangular pyramid, or a rectangular parallelepiped shape. When the internal space of the small chamber 66 is a pyramid shape, the small chambers 66 adjacent to the longitudinal direction (vertical direction in the mounted state) of the stay main body 62 are arranged with the apexes facing one side in the longitudinal direction, and intersect with the longitudinal direction. As for the small chambers 66 adjacent to each other, it is preferable to arrange the apexes toward the other side in the longitudinal direction.

In the second mode, the small chamber 66 is formed in a substantially hexagonal shape in a front view, and each of the plurality of small chambers 66 is partitioned by a partition wall 68. Thereby, the stay main body 62 has the small chambers 66 arranged in the longitudinal direction, the width direction, and the oblique direction intersecting with these directions.
Further, in the stay main body 62, the accommodating portion 64 is partitioned by a partition wall 70 formed in the longitudinal direction at the intermediate portion in the height direction, and the stay main body 62 has a plurality of small chambers 66 in the height direction (here, As an example, the structure is arranged in two stages.

  In the stay main body 62, the granular material 16 is enclosed in each of the small chambers 66, and the granular material 16 can be flowed by an external force applied to the partition wall 68 or the like in each small chamber 66. Thereby, when the knee 24 is bent and extended, the granular material 16 in each small chamber 66 flows, and the stay main body 62 is bent.

  In the stay main body 62, the partition walls 68 and 70 are made softer than the side surface portion 18 by making the partition walls 68 and 70 thinner than the thickness of the side surface portion 18. Further, the peripheral surface portion 20 of the stay main body 62 is made softer than the partition walls 68 and 70. Thereby, in the stay main body 62, the surface of the side surface portion 18 is suppressed from being uneven due to the granular material 16 enclosed in the small chamber 66.

  In the stay 60 configured as described above, the stay main body 62 is mounted on the knee 24 portion of the user's leg 22 by the same mounting means as the stay main body 12. In the stay main body 62, the granular material 16 adjusted so as to obtain a predetermined fluidity is enclosed in each of the small chambers 66. Accordingly, the user feels that the knee 24 is supported by the side surface portion 18 of the stay main body 62.

Further, when the knee 24 is bent and stretched, the granular material 16 in the small chamber 66 flows, so that the stay main body 62 is bent, and the knee 24 is bent and stretched while being supported by the stay main body 62. The Further, with respect to the sudden bending / extending operation of the knee 24, the flow of the granular material 16 is suppressed in the small chamber 66, and the stay main body 62 suppresses the sudden bending / extending operation of the knee 24.
Therefore, the stay main body 62 can suppress the bending / extending operation of the knee 24 with respect to the sudden bending / extending operation of the knee 24 while supporting the knee 24, so that the stay main body 62 can appropriately assist the bending / extending operation of the knee 24. .

By the way, when the stay main body 62 is attached to the leg 22 of the user, the stay main body 62 is vibrated in the vertical direction or the like due to vibrations caused by the user's walking or the like. In the granular material 16, there is a concern that a so-called Brazil nut effect may occur due to inclusion of particles having different weights (weights) due to different particle diameters (sizes).
In the Brazil nut effect, the particles contained in the container are subjected to vibration, so that heavy particles (relatively large particles) move upward and light particles (relatively small particles) move downward. Thereby, in the container, the fluidity of the particles in the upper part and the lower part is different, the fluidity of the particles in the lower part is lowered, and the fluidity of the particles in the upper part is increased.

  Temporarily, in the stay main body 62, when the accommodating part 64 is formed so that it may continue in the up-down direction at the time of mounting | wearing with the knee 24, a Brazil nut effect arises in the granular material 16 accommodated in the accommodating part 64. In the stay main body 62, the fluidity of the granular material 16 differs between the upper part and the lower part. In the stay main body 62, if the fluidity of the granular material 16 is different between the upper part and the lower part, the flexibility (ease of bending, easiness of bending) changes in the vertical direction, which is appropriate for the knee 24 bending and stretching operations. Assistance becomes difficult.

  Here, a plurality of small chambers 66 are formed in the accommodating portion 64 of the stay main body 62, and the accommodating portion 64 has a longitudinal direction that is vertical when the stay main body 62 is attached to the knee 24. It is divided into multiple parts. For this reason, in the stay main body 62, even if the Brazil nut effect occurs in the granular material 16 enclosed in the small chamber 66, it can suppress that a flexibility changes in a longitudinal direction. Thereby, in the stay main body 62, the bending / extending operation | movement of the knee 24 can be assisted appropriately, and a user can be provided with a sense of security about the bending / extending operation | movement of the knee 24.

  In the stay main body 62, a plurality of small chambers 66 are arranged in the width direction and the height direction, and the accommodating portion 64 is divided in the width direction and the height direction. For this reason, in the stay main body 62, when the knee 24 is bent, even if a portion in which the width direction or the height direction is the vertical direction is generated, it is possible to suppress the change in flexibility. Further, since the small chambers 66 are arranged not only in the longitudinal direction and the width direction but also in the diagonal direction in the stay main body 62, the stay main body 62 more effectively suppresses the change in flexibility due to the Brazil nut effect. it can.

  On the other hand, in the stay main body 62, the granular material 16 adjusted so that fluidity may differ between the some small chambers 66 may be accommodated. For example, in the stay main body 62, the intermediate portion in the longitudinal direction mainly corresponding to the knee 24 bends according to the bending / extending operation of the knee 24, and there is little bending on the thigh 26 side or the shin 28 side. From here, the fluidity of the granular material 16 in the small chamber 66 at both ends in the longitudinal direction of the stay main body 62 is compared with the fluidity of the granular material 16 in the small chamber 66 in the longitudinal intermediate portion of the stay main body 62. make low. As a result, the stay main body 62 is less likely to bend at both ends in the longitudinal direction. Therefore, the support of the thigh 26 side and the shin 28 side of the knee 24 can be stabilized, and the support of the knee 24 can be stabilized. Can be planned.

Further, in the stay main body 62, the fluidity of the powder particles 16 may be made different between the small chambers 66 arranged in the width direction, and the flow of the powder particles 16 between the small chambers 66 arranged in the height direction. May be different.
For example, it is possible to suppress the bending of the knee 24 by reducing the fluidity of the granular material 16 in the small chamber 66 on the bending side of the knee 24 in the width direction of the stay main body 62.

[Third embodiment]
The body appliance includes the following aspects.
A mounting body that is mounted so as to surround the joint site and applies a pressure to the joint site, and a longitudinal intermediate portion of a long hollow portion is opposed to the joint site and straddles the joint site. A body orthosis comprising: a support portion provided on the solid portion; and solid particles that are filled and accommodated in the hollow portion until at least the joint portion is reached.

The body appliance may include the following configuration.
The mounting body is a supporter body that is formed in a cylindrical shape and supports the operation of the joint part by inserting and mounting the joint part.
The support part accommodates a support body for a body support tool, and solid particles are accommodated in the support body so as to flow.
The mounting body may be mounted with a support by mounting means, and the mounting means may be an adhesive portion that is provided on the mounting body side of the support and adheres the support to the mounting body. The means may be a hook-and-loop fastener including a loop portion provided on one of the support and the mounting body and a hook portion provided on the other of the support and the mounting body and engaged with the loop portion.

In the third aspect, a part including the leg knee joint is applied as the joint part, and the body orthosis according to the third aspect is worn on a part including the leg knee joint as the joint part.
3rd aspect WHEREIN: "Axial direction of a mounting body" points out the axial direction of a cylindrical shape when the shape of a mounting body is maintained in a cylindrical shape. In the third aspect, the “axial direction of the mounting body” may be simply referred to as “axial direction”.
The “axial direction” in the third aspect is a direction sometimes referred to as a “vertical direction” in the technical field of knee supporters, and can also be referred to as a direction in which a leg is inserted into the wearing body. In the third aspect, the “circumferential direction of the mounting body” refers to the circumferential direction when the shape of the mounting body is maintained in a cylindrical shape.

FIG. 7 shows a knee supporter 80 as a body orthosis and a joint supporter in a third aspect in a side view.
As shown in FIG. 7, the knee supporter 80 includes a supporter body 82 as a mounting body. The supporter main body 82 is inserted with a human leg 22 and supports a knee 24 including a knee joint as a joint of the leg 22 in an intermediate portion in the axial direction. The supporter main body 82 supports the thigh 26 side (thigh 26 side of the knee 24) of the leg 22 in the upper part in the axial direction, and also supports the shin 28 side (in the lower part of the axial direction) of the leg 22 in the axial direction. The shin 28 side of the knee 24) is supported. The knee supporter 80 is worn so that the supporter body 82 covers the range from the thigh 26 side to the shin 28 side with the knee 24 (knee joint) of the leg 22 as the center.

  The knee supporter 80 can be applied to any structure as the supporter body 82, but the supporter body 82 is more preferably excellent in the feeling of fixation with respect to the knee 24 and more excellent in the bending and stretching properties of the knee joint.

  As such a supporter main body 82, one configured so as to generate predetermined elasticity (elastic modulus) in each of the axial direction and the circumferential direction is used, and the knee 24 side of the knee 24 is centered on the knee 24. A predetermined range between the knee 24 and the shin 28 side of the knee 24 is wrapped and supported in the circumferential direction. At this time, the supporter main body 82 has a configuration in which the elastic modulus in the axial direction and the circumferential direction is determined so as to obtain an appropriate tightening feeling for the knee joint.

  As the supporter main body 82, at least one direction (preferably both directions) of the axial direction and the circumferential direction is divided into a plurality of regions, and the elastic modulus in the axial direction and the elastic modulus in the circumferential direction are between adjacent regions. Different configurations may be used. Thus, for example, by changing the tightening force and the axial extension between the central portion (the knee 24 portion), the thigh 26 side portion, and the shin 28 side portion in the axial direction, A preferable tightening force can be applied to each of the thigh 26 side portion and the shin 28 side portion. Further, the supporter main body 82 has a different elastic modulus in the axial direction between the front side and the rear side (for example, by making the front side elastic modulus smaller than the rear side elastic modulus). The elasticity can be changed between the rear side and the leg 22 can be easily bent and extended, which is preferable.

  Such a supporter main body 82 can apply a knitted structure including a floating knitted structure as a knitted structure. When the knitting structure of the supporter body 82 is a knitting structure including a floating knitting structure, the density and distribution of the floating yarns are changed for each region in contact with the legs 22 when the supporter body 82 is manufactured. The elastic modulus in the axial direction can be easily adjusted, and the supporter body 82 having a different elastic modulus for each region can be easily manufactured.
