  The present invention will be described below based on preferred embodiments with reference to the drawings. The muscle strengthening tool of the present invention includes a steam heating tool and a wearing tool as components. The front view of one Embodiment of the mounting tool in the muscle strengthening device of this invention is shown by FIG. FIG. 2 is a rear view of the wearing tool shown in FIG. 3 and 4 are a sectional view taken along line III-III and a sectional view taken along line IV-IV in FIG. 1, respectively. The wearing tool 10 can be fixed to the leg or arm of the wearer. The mounting tool 10 has a substantially rectangular shape having a width direction X and a longitudinal direction Y that is orthogonal to the width direction X and has a length longer than the width direction X in the front view and the back view. More specifically, the wearing tool 10 roughly includes a container 20 for a steam heating tool (not shown) and a tongue piece 30. Hereinafter, each part will be described.

  The accommodating portion 20 has a structure in which a plurality of steam heating tools (not shown) can be fixed along the width direction X. The details are as follows. As shown in FIG. 3 and FIG. 4, the housing portion 20 is positioned outside the skin side sheet 21 facing the wearer's skin and the skin side sheet 21 when the wearing tool 10 is worn on the wearer. And an outer sheet 22. The skin side sheet 21 and the outer sheet 22 are both rectangular and have substantially the same shape. The skin-side sheet 21 and the outer sheet 22 are basically single-layer sheets, but are not limited thereto, and a multilayer structure composed of two or more layers or two or more sheets are stacked. Alternatively, it may be a multi-ply stack.

  As shown in FIGS. 1 and 2, the skin side sheet 21 and the outer sheet 22 are joined at positions of an upper side 23a and a lower side 23b extending in the longitudinal direction Y (in FIG. 1 and FIG. ). Moreover, the skin side sheet | seat 21 and the outer side sheet | seat 22 are joined also in the position of the side 24 opposite to the side in which the tongue piece part 30 mentioned above is arrange | positioned among the two side edges extended in the width direction X. (In FIG.1 and FIG.2, a junction part is shown with a dotted line.). Furthermore, the skin-side sheet 21 and the outer sheet 22 are joined by a joining portion extending in the longitudinal direction Y at a position 25 that bisects them in the vertical direction along the width direction X (in FIG. 1 and FIG. 2, joining). Part is indicated by a dotted line). As a result, as shown in FIGS. 3 and 4, the accommodating portion 20 has an opening 27 at one end in the longitudinal direction Y, and is a pocket-shaped accommodation defined by the skin side sheet 21 and the outer sheet 22. Two upper and lower spaces 26 are formed along the width direction X. By inserting a steam heating tool (not shown) into the housing space 26, the steam heating tool is disposed and fixed between the skin side sheet 21 and the outer sheet 22. Each accommodation space 26 is longer in the longitudinal direction Y than in the width direction X.

  Various means can be adopted for joining the skin side sheet 21 and the outer sheet 22 depending on the material of these sheets. For example, means such as stitching using a thread, fusing by heat, bonding using an adhesive, and bonding using ultrasonic waves can be employed. Among these means, considering that the wearing tool 10 of the present embodiment is to be worn on the wearer's body, it is preferable to use a suture which is a joining means having a good texture such as touch.

  Like the mounting tool 10 of the present embodiment, the plurality of storage spaces 26 for the steam heating tool are formed along the width direction X so that the mounting tool 10 to which the steam heating tool is fixed is attached to the wearer's leg. When it is wound around and fixed to the arm or the arm, the wearing tool 10 can sufficiently follow the contraction of the muscles (bending and stretching of the legs and arms). As a result, useless space is prevented from being generated between the steam heating tool and the wearer's leg or arm, and steam temperature generated from the steam heating tool is effectively applied to the wearer's leg or arm. In particular, since the length in the longitudinal direction Y of each accommodation space 26 is longer than the length in the width direction X, there is an advantage that the flexibility of the wearing tool 10 to which the steam heating tool is fixed is increased.

  From the viewpoint of making the above-described advantages more remarkable, it is preferable that both the skin-side sheet 21 and the outer sheet 22 have elasticity. In this case, it is preferable that both the skin side sheet 21 and the outer sheet 22 have elasticity in at least the longitudinal direction Y. More preferably, the skin-side sheet 21 and the outer sheet 22 are each made of a so-called two-way stretchable fabric having stretchability in two directions of the longitudinal direction Y and the width direction X.

  When both the skin-side sheet 21 and the outer sheet 22 have stretchability, it is preferable that the stretchability of the outer sheet 22 is higher than the stretchability of the skin-side sheet 21 at least in the longitudinal direction Y. When the wearing device 10 to which the steam heating device is fixed is wrapped around and fixed to the leg or arm of the wearer, it can follow the contraction of the muscle (bending and stretching of the leg and arm) more sufficiently. It is. High stretchability means that the elongation becomes high when compared with the same load. From this point of view, the degree of stretchability in the longitudinal direction Y of the skin side sheet 21 is preferably 100 to 300%, particularly 180 to 220% in elongation at the load of 2.25 kg, and the longitudinal direction of the outer sheet 22 The degree of stretchability of Y is preferably 100 to 400%, particularly 210 to 290% when the load is 2.25 kg. This elongation is measured using a constant speed extension tensile tester. The test piece is a rectangle with a length of 25 mm and a width of 16 mm. The tensile speed is 30 ± 2 mm / min, and the distance between chucks is 100 mm.

  The outer sheet 22 is preferably made of a fabric having a good texture. The outer sheet 22 preferably has sufficient air permeability. The outer sheet 22 can be composed of a knitted fabric such as tricot knitting, for example. Similarly, it is preferable that the skin side sheet | seat 21 is comprised from the fabric with the favorable texture. From the viewpoint of efficiently imparting steam heat generated from the steam heating tool fixed to the wearing tool 10 to the skin of the wearer, the skin side sheet 21 is preferably made of a material having sufficient water vapor permeability. . As such a material, for example, a mesh-like knitted fabric is preferably used.

  What is necessary is just to determine the dimension of the accommodating part 20 in the mounting tool 10 appropriately according to which part of the body the mounting tool 10 is mounted on. For example, when the wearing tool 10 is attached to the thigh, for example, the dimension in the width direction X is preferably 80 to 350 mm, particularly 150 to 250 mm, and the dimension in the longitudinal direction Y including the tongue piece is 350 to 600 mm.

And each tongue piece part 31 and 32 protrudes along the longitudinal direction Y from the side edge part by the side in which the opening part 27 in the accommodating part 20 is formed. Each tongue piece part 31 and 32 and the accommodating part 20 are joined by various means, such as stitching | suture, melt | fusion, adhesion | attachment.

  As shown in FIGS. 1 and 2, the protruding lengths in the longitudinal direction Y of the tongue pieces 31 and 32 gradually decrease along the width direction X. Specifically, the overhang length L1 of the first tongue piece portion 31 is larger than the overhang length L2 of the second tongue piece portion 32. In addition, although the mounting tool 10 of this embodiment has only two tongue piece parts, when it has three or more tongue piece parts, it is 1st, 2nd, 3rd along the width direction X, for example. When the tongue piece portion is provided, the overhanging length is made smaller in the order of the first tongue piece portion, the second tongue piece portion, and the third tongue piece portion.

  The extent of the overhang length of each tongue piece 31 and 32 is such that the ratio of L2 / L1 is 0.6 to 0.8, particularly 0.65 to 0.75. It is preferable from the viewpoint of the ratio, the ratio of the minimum upper arm circumference to the maximum upper arm circumference, and ergonomic viewpoint. Regarding the length of L1 itself, for example, it is preferably 50 to 150 mm, particularly 80 to 120 mm in the case of leg mounting, and 30 mm to 150 mm, particularly 50 mm to 80 mm in the case of arm mounting.

  Each tongue piece part 31 and 32 can be comprised from various fabrics, for example. The cloth used is stretchable, so that the operability when the wearer 10 on which the steam heating device is arranged and fixed is worn on the wearer's body is improved, and the body is tracked in the worn state. It is preferable from the viewpoint of improving the properties. In this case, it is preferable that the fabric used has elasticity in at least the longitudinal direction Y. The fabric is more preferably made of a so-called two-way stretch fabric having stretchability in two directions of the longitudinal direction Y and the width direction X. The degree of elasticity can be the same as the degree of elasticity of the skin side sheet 21 and the outer sheet 22 described above. Further, in the embodiment shown in FIGS. 1 and 2b, each of the tongue pieces 31 and 32 is separate from the housing part 20, but instead of this, they may be the same continuous body. When each tongue piece part 31 and 32 is the form which continued from the accommodating part 20, it is preferable to join the boundary of the accommodating part 20 and each tongue piece part 31 and 32.

At the front end portion on the side, there are attached portions 31 a and 32 a that can be fixed to the fixing portion 40. Each of the adherend portions 31a and 32a extends over substantially the entire width direction X of each tongue piece portion 31 and 32. Each of the adherend portions 31a and 32a is made of a material that can be detachably attached to the above-described attachment portion 40. For example, each of the adherend portions 31a and 32a can be constituted by a loop member or a hook member of a hook-and-loop fastener. In this case, the fastening portion 40 is constituted by a hook member or a loop member of a hook-and-loop fastener.

The slip-off prevention unit 41 is disposed at least at a position near one side edge along the width direction X in the wearing tool 10, specifically, a position near the upper side 23. This position is also a position closer to the first tongue piece portion 31 that is the tongue piece portion having the largest overhang length of the two tongue piece portions 31 and 32. Further, the slip-off prevention portion 41 is disposed at least at a substantially central position in the longitudinal direction Y of the wearing tool 10. The slip-off prevention unit 41 has a function of preventing the wear-out tool 10 from slipping when the wear tool 10 on which the steam heating tool is arranged and fixed is mounted on the wearer's body. The slip-off prevention part 41 is made of a high friction material. The high friction material referred to here is a material having a large frictional force with clothing (for example, trousers or spats) that is mounted on the wearer's body with the mounting device 10 on which the steam heating device is disposed and fixed. That is. The frictional force is a broad concept including not only a narrowly defined frictional force generated by rubbing objects but also a shearing force generated by engagement or the like.

  FIG. 5A shows a front view of the steam heating tool 50 used together with the mounting tool 10 having the above configuration. FIG.5 (b) is the bb sectional view taken on the line in Fig.5 (a). The steam heater 50 is defined by a pair of first edges 50a extending in the width direction X and a pair of second edges 50b extending in the longitudinal direction Y, which is a direction orthogonal thereto, when viewed from the front. It is a flat thing that has a rectangular shape. The length of the second edge portion 50b is larger than the length of the first edge portion 50a. The length of the second edge portion 50b is smaller than the length of the accommodation space 26 in the longitudinal direction Y of the mounting tool 10 described above. Similarly, the length of the first edge portion 50a is smaller than the length of the accommodation space 26 in the width direction X.

  Regarding the ratio of the lengths of the first edge 50a and the second edge 50b in the steam heater 50, the length of the first edge 50a: the length of the second edge 50b is 1: 1. A range of 5 to 1: 7, particularly a range of 1: 2 to 1: 5 is preferable from the viewpoint that it can be worn on the legs and arms with little discomfort while effectively heating the muscles.

  The steam heating tool 50 includes a water vapor generating unit 51 and a container 52 that houses the water vapor generating unit 51. The container 52 is flat and is composed of a plurality of sheet materials having the same shape. The accommodating body 52 may have only one accommodating portion that accommodates the water vapor generating portion 51, or may have two or more accommodating portions. When there are two or more accommodating parts, each accommodating part can also have a communication part. In the present embodiment, the housing body 52 has two housing portions. The two accommodating portions are arranged along the longitudinal direction Y. The two accommodating parts do not have a communicating part.

  As shown in FIG. 5B, in the container 52, the moisture permeable sheet 52 a and the non-moisture permeable sheet or the moisture permeable sheet (hereinafter, “non-moisture permeable sheet” and “non-breathable sheet”) are generic names. 52b) are joined to each other at a pair of first joining portions 53A located on both sides in the longitudinal direction Y. The sheets 52a and 52b are also bonded to each other at the pair of second bonding portions 53B located at the upper and lower ends of the width direction X. The joint portions 53A and 53B are formed in a closed ring shape at the peripheral edge portions of the sheets 52a and 52b. In addition, the sheets 52a and 52b are joined to each other at the third joint 53C extending in the width direction X at the center in the longitudinal direction Y. Both ends of the third joint portion 53C are connected to the second joint portions 53B, respectively. That is, two closed spaces are formed in the container 52 by the joint portions 53A, 53B, and 53C. This closed space is a housing part for the water vapor generating part 51.

  From the viewpoint of enhancing the feeling of wearing the steam heating device 50, as shown in FIG. 5B, a non-woven fabric 52c, which is a sheet material having a good texture, is disposed on the outer surface of the moisture-impermeable sheet 52b or the like. From the same viewpoint, the nonwoven fabric 52d is arranged on the outer surface of the moisture-permeable sheet 52a. The moisture permeable sheet 52a and the nonwoven fabric 52d, the hardly moisture permeable sheet 52b, and the nonwoven fabric 52c may be joined only at the joining portions 53A, 53B, and 53C, or may be joined partially within the sheet surface. The same applies to the moisture-permeable sheet 52a and the nonwoven fabric 52d.

  The moisture-permeable sheet 52a and the non-woven fabric 52d act as a ventilation layer 60a located on the side close to the wearer's skin when the steam heating device 50 is used. On the other hand, the moisture-impermeable sheet etc. 52b and the nonwoven fabric 52c act as the air-impermeable layer 60b located on the side far from the wearer's skin. That is, the steam heating device 50 has a breathable one side (breathing layer 60a), a breathable or non-breathable one side (breathable layer 60b), and a non-breathable nonwoven fabric 52d side facing the skin. 10 is fixed. In the present embodiment, the air-permeable layer 60a is composed of a moisture-permeable sheet 52a and a nonwoven fabric 52d, and the air-impermeable layer 60b is composed of a moisture-permeable sheet 52b and a nonwoven fabric 52c, but the air-permeable layer 60a and the air-impermeable layer 60b are respectively. You may be comprised only with the moisture-permeable sheet 52a and the hardly moisture-permeable sheet 52b.

  In the steam heating tool 50 of the present embodiment, the steam generating part 51 is accommodated in the container 52, and the steam is generated by utilizing the heat generated by the oxidation reaction of the oxidizable metal contained in the steam generating part 51. The water contained in the generating part 51 is heated to form water vapor, and the water vapor can be released to the outside through the ventilation layer 60a in the container 52. When the steam heating device 50 is disposed and fixed on the wearing device 10 so that the surface on the side of the ventilation layer 60a faces the wearer's skin, and the wearing device 10 is mounted on the wearer's body, the heat accompanying water vapor is generated by the user. It is applied directly to the skin.

The steam heating device 50 of the present embodiment is configured such that water vapor is preferentially released through the ventilation layer 60a by appropriately adjusting the air permeability of the ventilation layer 60a and the hardly breathable layer 60b. Specifically, the air permeability of the hardly air permeable layer 60b is made larger than the air permeability of the air permeable layer 60a. Here, the air permeability is a value measured by JIS P8117, and is defined as the time (seconds / 100 ml) in which 100 ml of air passes through an area of 645 mm ² under a constant pressure. Therefore, a high air permeability means that it takes time to pass air, that is, the air permeability is low. Conversely, a low air permeability means high air permeability. Thus, the magnitude of the air permeability and the level of air permeability are opposite to each other. In the present embodiment, when the air permeability of the gas permeable layer 60a and the gas permeable layer 60b is compared, the gas permeable layer 60a is higher than the gas permeable layer 60b.

  When the breathable layer 60b is breathable, the air permeability of the breathable layer 60b is from the viewpoint of suppressing the release of water vapor through the breathable layer 60b while ensuring the inflow of air through the breathable layer 60b. Is preferably 5 times or more, more preferably 10 times or more, the air permeability of the air-permeable layer 60a. Alternatively, it is also preferable that the ratio of the air permeability of the air-permeable layer 60a and the air-permeability layer 60b (the air-permeable layer 60a / the air-impermeable layer 60b) is 0.5 or less, particularly 0.2 or less. Thereby, it is possible to further reduce the release of water vapor through the hardly air-permeable layer 60b and further increase the release of water vapor through the air-permeable layer 60a. On the other hand, when the air-impermeable layer 60b is non-breathable, the inflow of air into the container 52 and the generation of water vapor are performed exclusively through the air-permeable layer 60a.

  When the breathable layer 60b is breathable, the breathability of the breathable layer 60b is preferably 30000 seconds / 100 ml or more, particularly 40000 seconds / 100 ml or more, especially 50000 seconds / 100 ml or more. On the other hand, the air permeability of the air-permeable layer 60a is 100 to 30000 seconds / 100 ml, particularly 1000 to 20000 seconds / 100 ml, regardless of whether the air-impermeable layer 60b is non-breathable or non-breathable. preferable.

In addition to this, the body surface temperature is 38 ° C. or more and less than 42 ° C., particularly 38 ° C. or more over a period of 2 to 12 hours, particularly 3 to 8 hours, with the steam heating device 50 being in contact with the body surface (skin). It has heat generation ability and water vapor generation ability that can be maintained below 41 ° C. These measurement methods are described in, for example, Japanese Patent Application Laid-Open No. 2005-199051 and Japanese Patent Application Laid-Open No. 2006-271963, which are related to the earlier application of the present applicant.

  Moreover, it is preferable that the steam heating tool 50 having the water vapor generating ability has a maximum attainable temperature due to heat generation of 38 ° C. or higher. Further, from the viewpoint of preventing low temperature burns and the like, it is preferable that the maximum temperature reached is 60 ° C. or less. The maximum temperature reached refers to the value of the temperature that reaches the highest point with the side of the ventilation layer 60a aligned with the measurement surface in accordance with JIS S4100.

  6 (a) to 6 (c) show a method of using the muscle strengthening device 100 including the steam heating device 50 and the mounting device 10 having the above configuration. These drawings show an example in which the muscle strengthening device 100 is attached to the thigh. First, as shown in FIG. 6A, the steam heating tool 50 shown in FIGS. 5A and 5B is inserted into the two housing spaces formed in the mounting tool 10, and the steam heating tool 50 is inserted. Is fixed to the mounting tool 10. At this time, the steam heating device 50 is arranged and fixed on the steam heating device 50 so that the side of the ventilation layer 60 a faces the skin side sheet 21 side of the wearing device 10.

  Next, as illustrated in FIG. 6B, the muscle strengthening device 100 is wound around the thigh of the wearer with the longitudinal direction Y of the wearing device 10 as the winding direction. At this time, the outer sheet 22 in the wearing tool 10 faces outward, and the slip-off prevention part 41 provided on the outer sheet 22 faces almost the front of the wearer's body. Furthermore, the muscle strengthening device 100 is arranged so that the first tongue piece portion 31 that is the tongue piece portion having the longest protruding length among the tongue piece portions 31 and 32 of the wearing device 10 is located on the upper side (that is, the buttocks side). Wrap. Then, the attached portions 31 a and 32 a of the tongue pieces in the wound muscle strengthening device 100 are fastened to the fastening portion 40. As a result, the mounting state shown in FIG. In the wearing state shown in the figure, the slip-off prevention part 41 provided on the outer sheet 22 of the wearing tool 10 faces almost the front of the wearer's body. If clothing such as pants or spats is worn under this condition, the muscle strengthening device 100 is effectively prevented from slipping off the thigh due to the frictional force generated between the fabric of these clothing and the slip-off preventing portion 41. Is done.

  By maintaining the state shown in FIG. 6C for a predetermined time, the steam heat generated from the steam heating tool is imparted to the wearer's leg. When the wearer's legs and arms are warmed by heat accompanied by water vapor, the muscle temperature of the legs and arms can be effectively warmed compared to when the user's body is warmed by heat not accompanied by water vapor. It became clear as a result of their examination. That is, the transmission of heat is remarkable. The reason for this is considered to be that the heat transfer efficiency is increased by the action of contact heat transfer in which the water vapor generated in the water vapor generating section 51 moves to the skin and the condensation heat released by the water vapor that reaches the skin. On the other hand, in heat without water vapor, only heat transfer by thermal diffusion occurs, so the thermal conductivity is low. And according to the steam heating tool 50 of this embodiment, it became clear as a result of examination by the present inventors that the muscles of the legs and arms were strengthened. Here, the muscle enhancement means that the muscle mass / muscle strength after use for a predetermined time increases or the muscle mass / muscle strength is predicted to decrease when the muscle strength / muscular strength is not warmed compared to before the muscle augmentation device of the present invention is worn. In this situation, both meanings of the case where the degree of attenuation is reduced are included.

  The present invention includes a method for evaluating a muscle enhancement effect by comparing the increase and decrease in muscle mass and strength before and after wearing a muscle augmentation tool for a predetermined time. That is, it has a water vapor generating part that uses heat generated by the oxidation reaction of an oxidizable metal, and heats the leg or arm with water vapor generated from a steam heating device that imparts water vapor to the skin, thereby strengthening the muscles A method for evaluating a muscle enhancement effect, the first step of measuring the muscle mass or muscle strength of a leg or arm as a target, the steam heating tool, a width direction, and a direction orthogonal to the width direction and the A muscle augmentation device provided with a substantially rectangular wearing device having a longitudinal direction longer than the width direction is wound around and fixed to the leg portion or the arm portion as a target with the longitudinal direction as a winding direction, A second step in which an operation of heating for a predetermined time is repeated for a predetermined period; a third step for measuring a muscle mass or a muscle strength of the leg or the arm portion to be the target after the predetermined period; and a first step. Measurements in the third step There is provided a method for evaluating anabolic effect and a fourth step of determining the presence, absence or extent of muscle building from a comparison of the values. Here, one wearing time is preferably at least 1 hour, particularly 1 to 20 hours, particularly 2 to 12 hours. The frequency of use is preferably continued for at least one day, particularly for one week or more. It can also be used continuously for a predetermined period. The measurement of the muscle mass can be performed using an MRI image as described later, for example. The measurement of muscular strength can be performed by, for example, the muscular strength measuring device used in the examples described later.

  As mentioned above, although this invention was demonstrated based on the preferable embodiment, this invention is not restrict | limited to the said embodiment. For example, the description of FIGS. 6A to 6C is an example in which the muscle strengthening device of the present invention is applied to the thigh. Instead, the muscle strengthening device of the present invention is applied to the lower leg, upper arm, and forearm. May be.

  Moreover, although the mounting tool 10 in the said embodiment has the pocket-shaped accommodation space 26 and the vapor | steam temperature heating tool 50 can be hold | maintained and fixed in the accommodation space 26, it replaces with this and vapor | steam is obtained by another means. The heating tool 50 may be fixed to the wearing tool 10. For example, the steam heating tool 50 can be detachably fixed to the mounting tool 10 using an adhesive.

  In addition, the steam heating device 50 in the above embodiment has the two steam generation parts 51, but instead of this, it may have only one steam generation part, or three or more. You may do it.
