Description

  The present invention relates to a supporter, and more specifically, to a supporter partially including a low stretchable part.

  The supporter has a function of protecting a part of a body such as a joint of a limb and a local part and a taping effect, and various types of supporters have been developed. The supporter is devised in various ways according to its use.

  For example, Japanese Patent Application Laid-Open No. 2003-52727 discloses a low tensile strength stronger than a stretchable high stretchable part, which is made of a stretchable tubular fabric and impregnated with resin from the front side to the back side of the tubular fabric. A knee supporter with a telescopic part is described.

  Japanese Patent No. 4130869 discloses that the back surface of the supporter body includes first to third protrusions, and the first protrusion is pressed against the patella ligament below the quadriceps muscle at the wearer's lower knee. And the second protrusion is disposed at a position where the tendon of the hamstrings and the lower tendon of the semimembranous muscle can be compressed in the wearer's popliteal region, and the third protrusion There is described a knee supporter in which a portion is arranged at a position where the tendon of the lower part of the hamstring biceps femoris can be pressed in the popliteal portion of the wearer. Further, in this knee supporter, a strip-shaped taping portion that exerts a taping action on a portion around the patella portion of the wearer's leg is provided integrally with the supporter body.

  Further, in Japanese Patent No. 3880590, each of the muscles constituting the upper body is composed of a plurality of stretch knitted parts having a stretch rate in one direction larger than that in the other direction perpendicular to the stretch direction and different stretch rates in the maximum stretch direction. Underwear that supports the movement of muscles is described by placing them at sites corresponding to the above and appropriately compressing those muscles.

JP 2003-52727 A Japanese Patent No. 4130869 Japanese Patent No. 3880590

  In the above-mentioned knee supporter disclosed in Japanese Patent Application Laid-Open No. 2003-52727, a low expansion / contraction part is provided so that the periphery of the knee joint can be effectively and easily supported. It does not pay attention to the growth (movement) of the skin. That is, the low expansion / contraction part described in Japanese Patent Application Laid-Open No. 2003-52727 is not provided in consideration that the elongation (movement) of the skin is difficult to be inhibited during wearing. For this reason, the supporter tends to inhibit the elongation (movement) of the skin, and there is a problem that stress on the skin and muscles cannot be effectively reduced.

  In the knee supporter described in Japanese Patent No. 4130869, the movement of leg muscles is promoted during mountain climbing, trekking, walking, etc., so that not only the knee joint but also the hip joint can be easily bent and extended. In order to enable easy walking, the first to third protrusions as described above are provided. Moreover, the strip | belt-shaped taping part which exerts a taping effect | action with respect to the patella part peripheral part of a wearer's leg is also provided.

  However, even in the invention described in Japanese Patent No. 4130869, attention is not paid to the elongation (movement) of the wearer's skin when worn. Therefore, as in the case of the invention described in Japanese Patent Application Laid-Open No. 2003-52727, there is a problem that stress on skin and muscles cannot be effectively reduced.

  In the underwear described in Japanese Patent No. 3880590, portions having different expansion / contraction ratios can be placed at various muscle positions so as to appropriately support various muscle movements in various work and various sports operations. It is arranged.

  However, even in the invention described in Japanese Patent No. 3880590, attention is not paid to the elongation (movement) of the wearer's skin when worn. Therefore, as in the case of the inventions described in the above-mentioned documents, there is a problem that stress on the skin and muscles cannot be effectively reduced.

  The present invention has been made to solve the above-described problems, and provides a supporter that can effectively reduce stress on the skin and muscles because it does not effectively protect muscles and the like. Objective.

  The supporter according to the present invention is provided with a main body portion made of a stretchable material, and is provided on the main body portion. The supporter has lower stretchability than the main body portion, and is orthogonal to the direction in which the wearer's skin extends at the wearing location. And a low expansion / contraction part extending in the direction. The low expansion / contraction part should just extend in the direction substantially orthogonal to the extension direction, and it should be interpreted that a certain amount of error is allowed. For example, a case where the low expansion / contraction portion is provided along a line called “KRAISSL line”, which serves as one reference when incising with a scalpel in a surgical operation, is also included in the scope of the present invention.

  You may extend the said low expansion-contraction part in the direction orthogonal to the extension (running | running | working) direction of a wearer's superficial muscle muscle fiber. Although any shape can be adopted as the shape of the low stretchable part, it is preferable to adopt a shape that curves so that the overall shape becomes a U-shape. In this specification, the “U shape” may be a shape that opens in one direction, and is not only a U shape, but also a V shape, a shape corresponding to a half cycle of a sine curve, It is defined to include various similar shapes, such as a shape along a parabola.

  Although the said low expansion-contraction part may be single, you may provide several low expansion-contraction part. In this case, it is preferable to arrange a plurality of low stretchable parts at intervals in the extension direction. When the plurality of low stretchable parts have a U-shape, it is preferable to vary the opening angles of the plurality of low stretchable parts. Here, in the present specification, the “opening angle” means an angle formed by a tangent line outside a portion near the end in the extending direction of the low stretchable part and a virtual line segment extending in the extending direction. It is defined as

  The low stretchable part can be formed by any method and material as long as it has lower stretchability than the main body part, but the stitched part, woven part, knitted part, sewn part, adhesive part, adhesive part, single part Or you may comprise at least 1 of a some sheet-like fiber structure, a resin part, and a rubber part.

  Since the supporter of the present invention has a low stretchable part which is lower in elasticity than the main body part and extends in a direction perpendicular to the extending direction of the wearer's skin at the wearing location, the various supporters provided with the conventional low stretchable part. As compared with the above, it is possible to reduce the influence of the low expansion / contraction part on the expansion / contraction of the skin, and to easily follow the main body part in the expansion / contraction direction according to the expansion / contraction of the skin. Moreover, a pressure can also be suitably given to a wearing location by a low expansion-contraction part. As a result, since the wearer's muscles and the like are not effectively protected, stress on the skin and muscles can be effectively reduced.

It is a front view of the supporter in Embodiment 1 of this invention. It is a rear view of the supporter shown in FIG. It is an enlarged view of a low expansion-contraction part. It is a schematic diagram which shows the extension (running | running | working) direction of the shallow muscle of a thigh rear surface, and a chrysal line. It is a schematic diagram which shows the extension (running | running | working) direction of the superficial muscle of the lower leg rear surface, and a crysle line. (A), (b) is a figure which shows the crysle line in each part of a human body.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS. In the following embodiment, an example of a supporter that can be worn on the thigh will be described. However, the supporter of this embodiment can be applied to a supporter that can be worn on various parts of the human body other than the thigh. For example, the present invention can also be applied to a supporter that can be worn on the lower leg or arm.

(Embodiment 1)
As shown in FIGS. 1 and 2, the supporter 1 includes a main body portion 2 made of a stretchable material and a low stretchable portion 3.

  The main body 2 has a substantially cylindrical shape. Any material can be used as the material of the main body 2 as long as it has elasticity. In the examples of FIGS. 1 and 2, the base layer made of chloroprene rubber and the surface of the base layer are attached. Adopted composite material with jersey fabric. As shown in FIGS. 1 and 2, the main body 2 may be manufactured by combining a plurality of parts, or may be configured by a single part. Moreover, although the main-body part 2 may be produced with the same raw material, the main-body part 2 may be produced by combining different materials.

  The low stretchable part 3 is a part that is provided in the main body 2 and has lower stretchability than the main body 2. The low stretchable part 3 has a shape that, after being worn, extends in a direction orthogonal to the extending direction in which the wearer's skin extends at the wearing location.

  In the example of FIG. 2, the two low expansion-contraction parts 3 are provided so that it may be located in the rear surface side of a wearer's thigh. The number of the low stretchable parts 3 may be singular or three or more. The two low expansion / contraction parts 3 are arrange | positioned at intervals in the said expansion | extension direction. When three or more low stretchable parts 3 are provided, the low stretchable parts 3 may be arranged at equal intervals or at different intervals.

  The low stretchable part 3 can be made of any material as long as it has lower stretchability than the main body part 2. For example, the low expansion / contraction part 3 can be formed by a sewing part having a width of about 5 mm to 10 mm. This sewing portion can be formed, for example, by sewing a thread having a lower elasticity than the thread constituting the main body 2 to the main body 2. In the example of FIG. 2, the low stretchable part 3 is formed by using a nylon thread on the front side and a polyester thread on the back side and sewing the main body part 2 to the body part 2.

  The low stretchable part 3 is formed by sewing with a flat seam in this example. However, the low stretchable part 3 is formed by weaving a thread that is less stretchable than the thread constituting the main body 2 into the main body 2. A knitting part formed by knitting a thread having a lower elasticity than the yarn constituting the main body 2, and a sewing formed by sewing a material having a lower elasticity than the material constituting the main body 2 to the main body 2. An attachment part formed by attaching a material having a lower elasticity than the material constituting the landing part and the main body part 2 to the main body part 2, and a material having a lower elasticity than the material constituting the main body part 2 in the main body part 2. Bonded part formed by bonding, single or plural sheet-like fiber structures having lower elasticity than the material constituting the main body part 2, resin parts and rubber parts having lower elasticity than the material constituting the main body part 2 You may comprise. Moreover, you may comprise the low expansion-contraction part 3 combining these suitably.

  As shown in FIG. 2, the low stretchable part 3 has a shape that curves so that the overall shape becomes a U-shape. However, any shape other than the U-shape can be adopted as long as it extends substantially in a direction orthogonal to the direction in which the wearer's skin extends at the wearing location after wearing. As described above, in the present specification, the “U-shape” includes a V shape, a shape corresponding to a half cycle of a sine curve, and a shape that opens in one direction such as a shape along a parabola. Although included, the “U-shaped” shape may be modified as appropriate.

  The low expansion / contraction part 3 should just extend in the direction orthogonal to the extending | stretching direction of the said skin after wearing, ie, the direction orthogonal to the extension direction of a wearer's superficial muscle muscle fiber. Thereby, even when the skin expands and contracts at the time of wearing, the degree of the influence of the low expansion and contraction part 3 on the expansion and contraction of the skin can be reduced. For this reason, compared with the various supporters provided with the conventional low expansion-contraction part, the main-body part 2 can be made to follow easily in this expansion-contraction direction according to the expansion-contraction of skin. Moreover, the low expansion / contraction part 3 can also apply a moderate pressure to a wearing location. As a result, since the wearer's muscles and the like are not effectively protected, stress on the skin and muscles can be effectively reduced.

  Even when the low stretchable part 3 is slightly deviated from the direction perpendicular to the skin stretching direction, the same effect can be expected because it has little influence on the skin stretching direction. Moreover, in the example of FIG. 2, the low expansion / contraction part 3 is comprised by the integral part extended continuously, while curving, but you may comprise the low expansion / contraction part 3 in a some part.

  Furthermore, in the example of FIG. 2, the low stretchable part 3 is provided in a part of the circumferential direction of the main body part 2, but the low stretchable part 3 may be provided over the entire circumference of the main body part 2. Moreover, you may make it selectively provide the low expansion-contraction part 3 only in the location which should apply a pressure according to a wearer's state. Further, not only the outer surface (outer peripheral surface) of the main body portion 2 but also the inner surface (inner peripheral surface) of the main body portion 2 or the inside of the main body portion 2 may be provided with the low stretchable portion 3.

  When the supporter 1 is actually worn, the supporter 1 normally extends in a direction (width direction of the supporter 1) orthogonal to the extension direction. When the supporter 1 is extended, the low stretchable part 3 is deformed and becomes a more open shape like a low stretchable part 3a indicated by a one-dot chain line in FIG. As a result, the opening angle θ1 of the low stretchable part 3a after deformation becomes larger than the opening angle θ of the low stretchable part 3. It is necessary to appropriately set the shape, position, and the like of the low stretchable part 3 so that the low stretchable part 3a after the deformation extends substantially in a direction orthogonal to the direction in which the wearer's skin extends at the wearing location. .

  In FIG. 3, the low expansion / contraction part 3 before wearing, the low expansion / contraction part 3a after wearing, and the crystal (KRAISSL) line 4 are written together. As described above, the low stretchable part 3 is deformed by wearing the supporter 1, but for example, the shape of the low stretchable part 3 is such that the low stretchable part 3 a after the deformation extends along the crystal line 4. It is conceivable to set appropriately. In the example of FIG. 3, the entire low expansion / contraction part 3 a extends on the crystal line 4, but the same effect can be expected even if it slightly deviates from the crystal line 4.

  Here, the crystal line 4 will be described with reference to FIGS. As shown in FIGS. 4 and 5, the superficial muscle line 5 along the extending (running) direction of the superficial myofibers on the back of the thigh and the back of the lower leg of the human body extends substantially in the longitudinal direction of the leg of the human body. . It is considered that the skin on the back side of the leg of the human body mainly expands and contracts in the extending (running) direction of the superficial muscle line 5. As shown in FIGS. 4 and 5, the crystal line 4 extends in a direction orthogonal to the above-described shallow muscle line 5. FIG. 6 shows the crystal line 4 of almost the entire human body.

  The low expansion / contraction part 3 may be arrange | positioned on the basis of the above-mentioned crystallized line 4. FIG. Also in this case, stress on the skin and muscles can be effectively reduced because the muscles and the like of the wearer are not effectively protected.

  Here, referring to FIG. 2 again, when a plurality of low stretchable parts 3 are provided at intervals in the skin stretching direction, the opening angles of the low stretchable parts 3 (the angles θ and θ1 in FIG. The corresponding angles are preferably different. Since the extension direction of the skin usually changes depending on the part of the human body, each low extension / contraction part 3 can be accurately extended in the direction perpendicular to the extension direction of the skin by making the opening angle of each low extension / contraction part 3 different from each other. Can exist. Thereby, since a wearer's muscle etc. are not protected effectively in multiple places, the stress to skin and muscles can be reduced effectively.

  Although the embodiment of the present invention has been described above, the above-described embodiment can be variously modified. The scope of the present invention is not limited to the above-described embodiment. The scope of the present invention includes, for example, whole body supporters, tights, various sportswear, is indicated by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims. Is done.
