Description

  The present invention relates to spats, and more particularly to spats that are suitably used for exercise.

  2. Description of the Related Art Conventionally, spats have been known in which a portion having a high elongation stress or tightening force is partially provided to have a taping function. For example, in Patent Document 1, a portion extending from the patella along the outer vastus to the greater trochanter, a portion extending from the patella to the inner vastus muscle, and a curve from the lower part of the gastrocnemius to both sides of the knee A spat is disclosed in which a tightening portion having a large tightening force is provided on the portion and no tightening portion is provided near the joint.

JP 2005-48332 A

  In the spats disclosed in Patent Document 1, the range of movement of the joint is ensured by dividing the tightening portion so that the ease of movement of the leg is not hindered. However, in the spats disclosed in Patent Document 1, a tightening portion is provided for the purpose of comfortably performing an operation and reducing fatigue, and no consideration is given to enhancing physical performance during exercise. Rather, by providing the tightening portion separately, the load of the tightening portion is not sufficiently applied to the movement of the muscles and joints, and improvement in physical performance during exercise can hardly be expected.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a spat that can improve performance during running or reduce performance degradation due to fatigue.

  The spats of the present invention capable of solving the above problems are spats having a base portion and a strong power portion exhibiting a higher elongation stress than that of the base portion, and the strong power portion is located outside the greater ankle muscle. A thigh lateral part extending through the vastus and above the patella; and a thigh medial part extending from the greater gluteal muscle through the medial vastus and above the patella; It is characterized by being connected to each other above the patella. If the strong power portion is provided in this way, the strong power portions of the outer thigh portion and the inner thigh portion act so as to support the extension of the hip joint. In other words, when the wearer bends the hip joint, the outer thigh and inner thighs are stretched, and the stretching stress causes the outer thigh and inner thighs to extend the hip joint. Kicking ability will be improved. As a result, it is possible to improve the performance during traveling and to reduce the performance degradation (decrease in running speed) due to fatigue.

  The base portion is preferably present from the lower abdomen to the upper abdominal muscle of the rectus femoris and is also present in the lower abdominal region of the biceps femoris and / or the lower abdominal region of the semi-tendonoid muscle. If the base portion is present in this manner, the pressure when wearing the spats is reduced, the movement of the hip joint is not hindered as much as possible, and the feeling of stickiness is reduced to improve the feeling of wearing the spats.

  It is preferable that the strong power portion further includes a knee covering portion that extends from above the patella through the patella and below the patella, and the knee covering portion is connected to the outer thigh portion and the inner thigh portion above the patella. By providing the knee covering portion as the strong power portion, the knee joint is supported by the knee covering portion. As a result, the knee joint is restrained from bending and the upper body from sinking during traveling, and the force generated by the hip joint extension is efficiently transmitted to the ground. Further, the vertical movement of the center of gravity of the body during traveling is suppressed, and the stability in the left-right direction is improved.

  It is preferable that an anti-slip material is provided on the skin surface side of the strong power portion below the patella. If an anti-slip material is provided under the patella, the hip and knee joints and the knee covering part will not easily slip due to flexion or extension of the hip joint or knee joint, and the hip joint or knee joint is suitably supported by the strong power part. Become so.

  The strong power part further includes an outer part of the lower leg that extends from the lower part of the patella through the outer side of the lower leg to the gastrocnemius, and an inner part of the lower leg that extends from the lower part of the kneecap to the inside of the lower leg part and reaches the gastrocnemius. It is preferable that the outer part and the inner side of the lower leg are connected to the knee covering part below the patella, and the outer part of the lower leg and the inner side of the lower leg are connected to each other through the gastrocnemius muscle. By providing the outer side of the lower leg and the inner side of the lower leg as a strong power part, the knee covering part is locked to the outer part of the lower leg and the inner side of the lower leg, and the knee covering part, the outer thigh part, and the inner thigh part are connected to the hip joint and It becomes difficult to shift due to flexion and extension of the knee joint. As a result, the extension of the knee joint is more suitably supported by the knee covering portion, and the extension of the hip joint is also more suitably supported by the outer thigh portion and the inner thigh portion.

  It is preferable that the outer side of the lower leg and the inner side of the lower leg are connected to each other at the lower part of the gastrocnemius. If the outer side of the lower leg and the inner side of the lower leg are provided in this way, the extension of the hip joint is strongly supported by the strong power part provided from the outer side of the thigh and the inner side of the thigh to the outer side of the lower leg and the inner side of the lower leg. .

  It is preferable that a non-slip material is provided on the skin surface side of the strong power part of the gastrocnemius. If the anti-slip material is provided in the gastrocnemius, the knee covering portion, the outer side of the lower leg, and the inner side of the lower leg are less likely to be displaced due to bending and extension of the knee joint. Therefore, the knee joint is suitably supported by the strong power part.

  It is preferable that the strong power portion further includes a buttock connecting portion that connects the left large gluteal muscle through the sacrum and / or the lumbar vertebra to the right large gluteal muscle and connects the strong power portions of the left and right legs. If the strong power parts of the left and right legs are connected by the buttock connection part, the left and right thigh outer part and thigh inner part are locked to the buttock connection part, and the thigh outer part and thigh inner part are It becomes hard to slip by extension. As a result, the extension of the hip joint is more suitably supported by the outer thigh portion and the inner thigh portion.

  In the spats of the present invention, since the strong power portion is provided so as to surround the thigh in the circumferential direction and extend from the buttocks to the knee, the strong power portion supports the extension of the hip joint during running. Therefore, the power for swinging down the legs during running and the power for kicking the ground are improved, and it is possible to improve performance during running and to reduce performance deterioration (running speed reduction) due to fatigue.

  The spats of the present invention are suitably used for exercise, and are particularly suitably used for exercise involving running. The spats of the present invention are partially provided with a strong power portion exhibiting a high elongation stress, and this strong power portion supports the extension of the wearer's hip joint to improve performance during running or fatigue. It is possible to reduce the performance drop (running speed drop) due to. In addition, the spats of the present invention can be expected to reduce performance degradation due to fatigue not only during running but also during walking.

  The cause of the decrease in running speed during running was examined by the present inventors through experiments with general runners.When fatigue occurred, the hip extension force decreased and the leg swinging force and ground force were reduced. It became clear that the kicking force was reduced, and this was found to be one of the biggest causes of the decrease in running speed. Specifically, it is clear that the ability to extend the hip joint when the thigh is lifted and then swung down, and the force to extend the hip joint when the foot kicks the ground, significantly affects the running speed. became. In addition, when the foot touches the ground, the knee joint can bend greatly and the upper body sinks due to inability to withstand the impact of the grounding, and the vertical movement of the center of gravity of the body increases. It became clear that

  Based on the above findings, the spats of the present invention are characterized in that a strong power portion is provided so as to support the extension of the hip joint. Furthermore, the spats of the present invention are preferably further provided with a strong power portion so as to support the knee joint in order to efficiently transmit the force generated by the hip joint extension to the ground.

In the present invention, the upper side of the leg knee is referred to as “thigh (part)”, and the lower side of the leg is referred to as “lower leg (part)”. In the following description, the names of muscles, skeletons, and the like representing each area (portion) of spats are represented with reference numerals shown in FIG.

  The spats according to the first embodiment will be described with reference to FIG. FIG. 1A shows a front view of the spats according to the first embodiment, and FIG. 1B shows a rear view of the spats shown in FIG. In the drawing, the strong power part is represented by hatching, and each part constituting the strong power part (for example, the boundary between the thigh outer side part and the thigh inner side part) is represented by a dotted line for convenience.

  FIG. 1 shows a spat 1 (1A) that covers the wearer's waist and knees. The spats 1 </ b> A have a base portion 2 and a strong power portion 3 that exhibits a higher elongation stress than the base portion 2. The strong power unit 3 includes an outer thigh portion 4 that extends from the greater gluteal muscle 21 through the outer vastus muscle 22 and above the patella 28, and an inner thigh that extends from the greater gluteal muscle 21 through the inner vastus muscle 23 and above the patella 28. The outer thigh portion 4 and the inner thigh portion 5 are connected to each other above the greater gluteal muscle 21 and the patella 28. That is, the outer thigh part 4 and the inner thigh part 5 are provided so as to extend from the buttocks to the knees while surrounding the thigh in the circumferential direction. By providing the outer thigh portion 4 and the inner thigh portion 5 as the strong power portion 3, the outer thigh portion 4 and the inner thigh portion 5 support the extension of the hip joint when the wearer's hip joint is bent. Act on. That is, when the hip joint bends, the outer thigh portion 4 and the inner thigh portion 5 are stretched, and the outer thigh portion 4 and the inner thigh portion 5 act so as to extend the hip joint by the extension stress (tensile stress), and the legs are swung down. Strength and ability to kick the ground will be improved. As a result, it is possible to improve the performance during traveling and to reduce the performance degradation (decrease in running speed) due to fatigue.

  In addition, although the bending of the hip joint can be somewhat restricted by providing the outer thigh portion 4 and the inner thigh portion 5 as the strong power portion 3, the performance during running is hardly affected by the bending operation of the hip joint. Rather, as described above, in order to improve the performance during running, it is important to increase the force for extending the hip joint.

  The outer thigh outer portion 4 and the inner thigh portion 5 are provided on the greater ankle muscle 21, but the outer thigh outer portion 4 and the inner thigh portion 5 may be provided so as to overlap at least a part of the greater ankle muscle 21, and preferably on the buttocks It is provided so as to cover the top.

They are connected to each other at the lower part of the tibia 31. That is, the ankle outer part 11 and the ankle inner part 12 are provided so as to surround the lower leg part in the circumferential direction. By providing the ankle outer part 11 and the ankle inner part 12 as the strong power part 3, the knee covering part 7, the lower leg outer part 8, and the lower leg inner part 9 are not easily displaced upward when the knee joint is bent. Thus, the knee covering portion 7 can more suitably support the extension of the knee joint. Further, the extension of the hip joint is suitably supported by the outer thigh portion 4 and the inner thigh portion 5.

  The spats according to the ninth embodiment and the tenth embodiment will be described with reference to FIGS. 9A shows a front view of the spats according to the ninth embodiment, FIG. 9B shows a side view of the spats shown in FIG. 9A, and FIG. 9C shows FIG. The back view of spats shown in FIG. FIG. 10A shows a front view of the spats according to the tenth embodiment, FIG. 10B shows a side view of the spats shown in FIG. 10A, and FIG. 10C shows FIG. The back view of spats shown in FIG. In addition, about the spats which concern on a 9th embodiment and a 10th embodiment, description of the part which overlaps with the said description is abbreviate | omitted.

  The spats 1 (1J) shown in FIG. 9 and the spats 1 (1K) shown in FIG. 10 are basically the same as the spats 1H shown in FIG. A strong power unit 3 is provided. In the spats 1J, the buttocks connection portion 6 is not provided, and the strong power portions 3 of the left and right legs are provided separately. Thus, the buttocks connecting portion 6 may not be provided as the strong power portion 3, but the buttocks connecting portion 6 is provided in order to prevent the outer thigh outer portion 4 and the inner thigh inner portion 5 from being easily displaced by the flexion or extension of the hip joint. It is preferred that

  In the spats 1K, the buttock connecting portion 6 is provided in a substantially V shape with the left and right legs. That is, the buttocks connection portion 6 extends from the greater ankle muscle 21 to the sacrum 27 and / or the lumbar spine 27 (that is, extends upward and inward from the greater ankle muscle 21), and the greater ankle muscle 21 to the intestine. It is composed of an outer heel connecting portion that extends to the skeleton (that is, extends upward and outward from the greater gluteal muscle 21). In this case, it is easy to provide the strong power portion 3 from the outer thigh portion 4 or the inner thigh portion 5 to the buttocks connection portion 6. For example, by attaching a belt-like member having a high elongation stress to the base material of the spats so that the left and right buttocks cross each other, the strong power portion 3 is stretched from the thigh outer portion 4 to the buttocks connection portion 6 (inner buttock connection portion). It becomes possible to form easily from the inner side part 5 to the collar part connection part 6 (outer collar part connection part).

  Next, constituent materials for the base portion and the strong power portion will be described. The base material and the strong power part are not particularly limited as long as the strong power part exhibits a higher elongation stress than the base part. The base part and the strong power part preferably have elasticity, and in order to extend the same length, the base part requires a relatively weak force, and the strong power part requires a relatively strong force It is preferable that

  The elongation stress is obtained by measuring the stress at 30% elongation. Specifically, it is obtained by pulling a test piece to be measured with a tensile tester and measuring the stress at that time. At this time, the test piece cut out with a width of 1 inch is fixed between the fasteners so that the holding interval is 100 mm. Then, while pulling the test piece at a pulling speed of 200 mm / min, the stress when the distance between the fasteners becomes 130 mm is measured, and the value at this time is taken as the elongation stress.

  As the value of the elongation stress of the base portion (stress at 30% elongation), for example, it is preferably about 0.3N to 2.0N, and the value of the elongation stress of the strong power portion (stress at 30% elongation) For example, it is preferably about 1.0N to 6.0N. These values may be appropriately determined in consideration of the wearer's age, gender, physical strength, and the like.

  As a method of providing the base portion and the strong power portion, (1) a method in which the base portion and the strong power portion are made of materials having different elongation stresses, and the base portion and the strong power portion are formed by connecting these materials; (2) The base part and the strong power part are each composed of woven or knitted fabric, and the woven structure or woven density of the woven cloth is changed, the knitted structure or knitted density of the knitted fabric is changed, or the woven or knitted cloth is A method of forming a base part and a strong power part by changing the type of yarn (for example, whether or not an elastic yarn is used), thickness, etc., and generating a difference in elongation stress, and (3) a spats base material A method in which a sheet member having a high elongation stress is partially attached, the part to which the sheet member is attached is a strong power part, and the other part is a base part. (4) An elastomer material is applied to a base material of spats. Part where elastomer material is applied Strong power unit, a method, and the like to the base portion other portions.

  Examples of the material constituting the base portion and the strong power portion by the method (1), and the base material used by the method (3) and the method (4) include woven fabric, knitted fabric, and elastomer (for example, Natural rubber, synthetic rubber, synthetic resin such as polyurethane) and the like. Examples of the material of the sheet member having a high elongation stress used in the method (3) and the elastomer material used in the method (4) include natural rubber; synthetic rubber such as styrene-butadiene copolymer and polyisobutylene; Examples thereof include synthetic resins such as polyurethane, polyether / polyester, polybutylene terephthalate and polytrimethylene terephthalate. Moreover, you may use the woven fabric, the knitted fabric, the nonwoven fabric, etc. which have a stretching property as a sheet | seat member with the high elongation stress used by the method of said (3).

  The spats of the present invention are preferably provided with a non-slip material on the skin surface side of the strong power part. It is preferable that the anti-slip material is provided so that the strong power portion is not easily displaced when the hip joint or the knee joint is bent or extended.

  For example, in the case of the spats 1A up to above the knee as shown in FIG. 1 or when the portion below the knee covering portion 7 is not provided as the strong power portion 3 (that is, the lower end of the strong power portion 3 is the outer thigh portion) 4 and the thigh inner part 5), it is preferable that a non-slip material is provided on the skin surface side of the strong power part 3 above the patella 28. If a non-slip material is provided above the patella 28, the outer thigh portion 4 and the inner thigh portion 5 are less likely to be displaced due to flexion or extension of the hip joint. Further, in the case of the spats 1A up to the knee as shown in FIG. 1, it is also preferable that an anti-slip material is provided above the patella 28 along the entire circumference of the skirt of the spats.

  In spats that extend below the patella 28 (that is, spats up to below the knees or ankles), it is preferable that a non-slip material is provided on the skin surface side of the strong power portion 3 below the patella 28. If a non-slip material is provided below the patella 28, the outer thigh portion 4, the inner thigh portion 5, and the knee covering portion 7 are not easily displaced due to flexion or extension of the hip joint or knee joint. Therefore, the hip joint and the knee joint are suitably supported by the strong power unit 3. Further, in the case of the spats 1B and 1D up to below the knee as shown in FIG. 2 and FIG. 4, it is preferable that a non-slip material is provided below the patella 28 along the entire circumference of the skirt of the spats.

  In spats in which the lower crus outer part 8 and the lower crus inner part 9 are provided as the strong power part 3, it is preferable that an anti-slip material is provided on the skin surface side of the strong power part 3 of the gastrocnemius muscle 30. If the anti-slip material is provided on the gastrocnemius muscle 30, the knee covering portion 7, the outer side portion 8 of the lower leg, and the inner side portion 9 of the lower leg are less likely to be displaced due to flexion or extension of the knee joint. Therefore, the knee joint is suitably supported by the strong power unit 3.

  FIG. 11 shows an example in which an anti-slip material is provided on the spats 1H shown in FIG. FIG. 11A shows a front view of the spats according to the eighth embodiment provided with an anti-slip material, and FIG. 11B shows a side view of the spats shown in FIG. c) represents a rear view of the spats shown in FIG.

  In the spats 1 (1L) shown in FIG. 11, the anti-slip material 13 is provided on the skin surface side of the strong power portion 3 below the patella 28, and the anti-slip material 14 is provided on the skin surface side of the strong power portion 3 of the gastrocnemius muscle 30. It has been. The anti-slip members 13 and 14 are not directly visible from the outside of the spats, but in FIG. 11, the anti-slip members 13 and 14 are shown so as to be visible with a solid line for easy understanding. In the spats 1L provided with the anti-slip materials 13 and 14, even if the hip joint and the knee joint are bent or extended, the anti-slip materials 13 and 14 make it difficult for the strong power portion 3 to shift.

  As the anti-slip material, a conventionally known elastic body such as natural rubber, silicone or polyurethane may be used. However, in order to have a higher anti-slip effect, a woven fabric composed of yarn containing nanofibers having a fiber diameter of 1 μm or less (hereinafter sometimes referred to as “nanofiber yarn”) as an anti-slip material. It is preferable to use a knitted fabric or a non-woven fabric. The anti-slip material composed of the nanofiber yarn has a large specific surface area of the fiber and a large number of fiber gaps. Therefore, the non-slip material composed of the nanofiber yarn has a high adsorptivity to the skin and is excellent in the anti-slip effect.

  Further, as the anti-slip material, it is more preferable to use a woven fabric composed of nanofiber yarns having a fiber diameter of 1 μm or less. By using a woven fabric composed of nanofiber yarns as an anti-slip material, each nanofiber is difficult to break, making it easier for nanofibers to be present as long fibers, and providing a good fiber gap between the nanofibers. The anti-slip effect of the anti-slip material is enhanced.

  Hereinafter, the present invention will be described in more detail with reference to examples, but the scope of the present invention is not limited thereto.
