JP 2006-233389 A

  For example, even a general woman who is not very confident in how to walk, there are many people who want to show her walking beautifully in a fashion where you can see at least the leg lines. In the case of an unfamiliar way of walking to show leg transport clearly, walking may become unnatural and may hinder smooth walking motion. In addition, it is difficult to walk consciously to show how to walk cleanly, and it is tired compared to normal times, so it is necessary to realize clean leg walking even when walking as usual. It has been.

  In the prior art described in Patent Document 1 described above, the edge of the fabric is curved, and the thigh is pulled inward using the tensile force when the fabric is linearly deformed according to the body shape. In addition, by trying to pull the crus outward, the effect of correcting the posture and body shape is to be obtained, and it was not considered to show the leg transport beautifully during walking. Also, in the spats described in Patent Document 1, when worn, the inner thigh is always subjected to inward pulling force and the lower thigh is subjected to outward pulling, which hinders natural walking movements. There was a problem.

  The present invention has been made to solve such problems, and it makes it easy for the wearer to make the knees face forward without being particularly aware of it, making it possible to make the legs carry beautifully during walking. An object is to provide a bottom clothing.

  A bottom garment according to the present invention is a bottom garment that covers at least a part of the lower body of a wearer, a pair of left and right cylindrical main body portions that are formed of stretchable fabric and covers a wearer's knee, and a belt And a tightening portion having a tightening force higher than that of the fabric of the cylindrical main body portion, and the tightening portion is arranged in a spiral shape, and obliquely downward from the front side position above the knee portion to the midline side The back side of the knee extends obliquely downward and outward with respect to the midline, returns to the front side again, and continues to the front side position below the knee. .

  According to such a bottom garment, the band-shaped tightening portion is disposed obliquely downward in a spiral manner from the position above the front knee to the midline, and continues to the position below the front knee. Is formed. Accordingly, the upper tightening portion is disposed along the position corresponding to the greater adductor muscle above the knee, and the lower tightening portion is disposed along the position corresponding to the anterior tibial muscle below the knee. Therefore, an internal force can be applied on the knee and an external force can be applied below the knee by the series of tightening portions. The adductor muscle is originally a muscle that moves inwardly, but the upper tightening part further promotes its action to rotate the upper part of the knee and strengthens the action of the anterior tibial muscle in the lower knee. By applying an outward force, it is possible to rotate the lower knee and prevent the knee from opening outward, and to facilitate the bending operation of the ankle. As a result, it is possible to carry a clean leg and to realize a smooth walking motion only by walking without the wearer being particularly conscious.

  In addition, when a virtual straight line that passes through the center of the knee portion in the width direction and extends in the longitudinal direction of the wearer's leg portion is the front leg center line L1, the tightening portion is the front leg center on the front side of the leg portion. It may be arranged in a spiral form from the position of the line L1, return to the front side again through the back side of the knee, and continuously arranged to the position of the front leg center line L1 below the knee.

  In addition, when a virtual straight line that passes through the center of the knee portion in the width direction and extends in the longitudinal direction of the wearer's leg portion is the front leg center line L1, the tightening portion is the front leg center on the front side of the leg portion. It is spirally arranged from the position outside in the width direction from the line L1, passes through the front leg center line L1 above the knee, returns to the front side again via the back side of the knee, and below the knee The configuration may be such that it passes through the front leg center line L1 and is continuously arranged to a position inside the front leg center line L1 in the width direction.

  In addition, when an imaginary straight line that passes through the center in the width direction of the knee and extends in the longitudinal direction of the wearer's leg is defined as the front leg center line L1, the inclination angle θ of the tightening part with respect to the front leg center line L1 is In the flat state, the configuration may be 25 degrees or more and 50 degrees or less.

  The tightening portion has a position corresponding to the center portion of the popliteal portion of the wearer as a reference point, and the height positions of the upper end portion and the lower end portion of the helical tightening portion are equidistant from the reference point. It may be arranged in such a manner.

  Further, the tightening portion may be formed by changing the elongation of a part of the cylindrical main body, or may be formed by attaching a batter to the cylindrical main body.

  The bottom clothing may be any of leggings, girdle, spats, sports tights, leotards, and body suits.

  The tubular garment according to the present invention is a tubular garment that covers at least the knee of the wearer, the tubular main body covering the wearer's knee formed of stretchable fabric, and a belt And a tightening portion having a tightening force higher than that of the cloth of the cylindrical main body portion, the tightening portion being arranged in a spiral shape, obliquely from the position on the front side above the knee portion to the midline side It extends downward, extends the back side of the knee diagonally downward to the outside of the center of the body, returns to the front side again, and continues to the front side position below the knee part. .

  According to such a tubular garment for knees, the band-shaped tightening portion is disposed obliquely downward in a spiral manner from the position above the knee on the front side to the midline side, and below the knee on the front side. It is formed continuously to the position. Accordingly, the upper tightening portion is disposed along the position corresponding to the greater adductor muscle above the knee, and the lower tightening portion is disposed along the position corresponding to the anterior tibial muscle below the knee. Therefore, an internal force can be applied on the knee and an external force can be applied below the knee by the series of tightening portions. The adductor muscle is originally a muscle that moves inwardly, but the upper tightening part further promotes its action to rotate the upper part of the knee and strengthens the action of the anterior tibial muscle in the lower knee. By applying an outward force, it is possible to rotate the lower knee and prevent the knee from opening outward, and to facilitate the bending operation of the ankle. As a result, it is possible to carry a clean leg and to realize a smooth walking motion only by walking without the wearer being particularly conscious.

  According to the bottom garment and knee tubular garment of the present invention, it is possible to beautifully carry the legs when walking without special consciousness. it can.

It is a front view which shows the supporter for knees which concerns on 4th Embodiment of this invention.

  Prior to the description of the embodiment, with reference to FIG. 1, a beautiful leg line (leg leg beauty) as the background of the present invention will be described. In addition, the term which shows the direction used in this specification is defined as follows. That is, on the basis of a state where the human body is upright, a direction in which a portion close to the head among the target parts such as the thigh is located is “up”, and the opposite direction is “down”. In addition, when a central axis (midline) passing through an erect human body in the longitudinal direction is assumed, the direction from the central axis (midline) to the back side is “rear” and “rear side” The opposite directions are “front” and “front side”. The direction away from the central axis (median line) is “out”, and the direction approaching the central axis (median line) is “in”.

  FIG. 1 is a front view schematically showing a leg portion, and FIG. 1A shows a posture when both knees are opened to the outside. FIG. 1B shows the posture when the thigh is rotated inward. FIG. 1C shows a posture when the thigh is rotated inward and the crus are rotated outward. FIG. 2 is a diagram illustrating the position of the greater adductor muscle of the human body, and FIG. 3 is a diagram illustrating the position of the anterior tibial muscle of the human body.

  The inventor of the present application is not confident in the way to walk, but at least in the fashion where the leg line is visible, it is a means for realizing the beauty of the leg line when walking, mainly targeting general women who want to walk cleanly. Decided to pursue. As shown in FIG. 1 (a), it was found that when the knees were opened outwards and the knee wobbling became a great way of walking, the leg transport could not be seen clearly. It has been found that when the great adductor muscle M1 and the anterior tibial muscle M2 cannot be used well, the knee is easily opened outward.

  From the state shown in FIG. 1 (a), when an inward force is applied on the knee to strengthen the function of the greater adductor muscle M1, the inward force acts to below the knee. As shown in FIG. 1B, when the knee is turned inward, the function of the anterior tibial muscle is inhibited, and the ankle becomes difficult to bend. For example, it may lead to slipping or tripping. For this reason, it was found that the leg transport does not become straight and does not result in a state of walking cleanly.

  Therefore, from the state shown in FIG. 1 (b), when an outward force is applied below the knee to strengthen the function of the anterior tibial muscle M2, the inward force F1 does not act down to the knee. As shown in FIG. 1C, when the influence of the inward force F1 does not reach to below the knee, the anterior tibial muscle M2 is easy to work and the ankle can be bent firmly. As a result, clean leg transportation without opening the knee is realized.

  Therefore, by strengthening the function of the greater adductor muscle M1 and strengthening the function of the anterior tibial muscle M2, smooth movement of the knee during walking and restraining the opening of the knee can achieve clean leg transportation. It has been found. Therefore, the inventor of the present application can suppress the opening of the knee and easily carry the leg straight by adopting a structure that supports the movement of the greater adductor muscle M1 and supports the movement of the anterior tibial muscle M2. The present invention was completed by obtaining knowledge that the beauty of the leg line during walking can be realized.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, the same code | symbol is attached | subjected to the same element and the overlapping description is abbreviate | omitted.

  With reference to FIGS. 4-6, the long type leggings (bottom clothing) in this embodiment are demonstrated. 4 is a front view of a long type legging, FIG. 5 is a rear view of the long type legging, and FIG. 6 is a perspective view showing the long type legging from the right front side.

  As shown in the figure, a long-type legging 10 includes a main body 1 that covers from the waist to the thigh, knee, and lower leg, and a belt-like support line that is sewn to a part of the main body 1. 2 (tightening part). The main body 1 includes a crotch main body 11 that covers the lower abdomen, crotch, buttocks, and waist, and a pair of left and right cylindrical main bodies that are formed continuously from the crotch main body 11 and cover the left and right legs, respectively. The parts 12 and 12 are configured as main parts.

  The support line part 2 is sewn to the cylindrical main body part 12, and a position on the front side above the knee part is an upper end 2T, and a position on the front side below the knee part is a lower end 2U. The support line portion 2 extends obliquely downward from the upper end 2T toward the midline, extends obliquely downward to the outside of the center of the body, and continues in a spiral manner to the lower end 2U. Yes. Above the knee part of the support line part 2, it arrange | positions corresponding to the site | part in which the large adductor of the thigh is located, and is arrange | positioned helically so that the internal force F1 may be provided. Below the knee part of the support line part 2, it arrange | positions corresponding to the site | part in which the anterior tibial muscle is located, and is arrange | positioned helically so that external force F2 may be provided. In addition, the support line part 2 does not need to make the width | variety of all the parts from the lower end 2U to the upper end 2T the same width.

Further, if a virtual line extending in the longitudinal direction (the vertical direction in the figure) passing through the center in the width direction on the front side of the leg portion is a front leg center line L1, the upper side of the support line part 2 is the leg center line L1. position through the inside from the legs before the center line L1 (core body L ₀ side) from the lower side of the support line 2 passes through the outside of the leg before the center line L1, and is arranged to the position of the legs before the center line L1 . Moreover, it is preferable that the support line part 2 is arrange | positioned equally up and down centering on the popliteal Q in the wearing condition (refer FIG. 5).

  The main body 1 and the support line 2 are made of a stretchable material. The support line portion 2 is configured to have a tightening force higher than that of the fabric of the cylindrical main body portion 12. As the material of the main body 1, a bare tengu can be used, and as the support line part (clothing, backing) 2, a satin power net can be used.

  As the material of the main body 1, other elastic materials such as two-way raschel and double raschel may be used. As the support line unit 2, a power net or a triconnet may be used.

  Here, the inventor of the present application conducted an extension recovery test (at 50% extension) in order to measure the extension recovery force that gives the body part 1 and the support line part 2 a tightening force. In this test, a test piece having a width of 2.5 cm and a length of 16.0 cm, in which the material radial direction (the wale direction) is the length direction of the test piece, was used. With the longitudinal direction of the test piece being the vertical direction, the test piece having the upper part 2.5 cm and the lower part 3.5 cm held between the clips is attached to a constant speed extension type tensile tester, and the test piece is made at a speed of 30 ± 2 cm / min. The stress applied to the test piece is removed after extending to 80%, and the stress applied to the test piece at the time of 50% elongation when the test piece returns to the original length is recorded and recorded for two test pieces. The average value of the stress was used as the elongation recovery force.

  Further, in the present invention, “wear pressure” is obtained by measuring the pressure applied to the leg surface by using a leg dummy model with a built-in pressure sensor, and wearing the leg dummy model with clothing having legs. .

  As a result, it was found that the extension recovery force of the main body 1 in the present embodiment is preferably in the range of 40 to 110 cN, and the extension recovery force of the support line portion 2 is preferably in the range of 150 to 350 cN. Further, the support line portion 2 is sewn so that the expansion / contraction direction (ground direction) that can exert the most tightening force is the longitudinal direction of the support line portion 2. Thereby, the force generated by the expansion and contraction of the support line portion 2 efficiently supports the actions of the greater adductor muscle M1 and the anterior tibial muscle M2.

The long type leggings 10 in this embodiment have the effects described below by including such a support line portion 2. When the leggings 10 are worn, the support line portion 2 having a strong tightening force extends, and further expands and contracts according to the movement of the wearer. According to such leggings 10, support line portion 2 of the band-shaped, the position of the front side of the above the knee from (2T) to the body center L ₀ side, is disposed obliquely downward, the back side of the knee It is continuously formed in one turn to the front side position (2U) below the knee. Thereby, the support line part 2 is arrange | positioned along the position corresponding to the greater adductor muscle M1 above the knee part on the upper side of the support line part 2, and the lower part side of the support line part 2 is below the knee part. Since the support line portion 2 is arranged along the position corresponding to the anterior tibial muscle M2, the inward force F1 acts on the knee and the outward force F2 acts below the knee. Can be made. Therefore, the greater adductor muscle M1 is originally a muscle that moves inward, but the upper support line portion 2 further promotes its action to rotate the knee on its inner side, and the anterior tibial muscle M2 works. By strengthening and applying an outward force F2 below the knee, it is possible to rotate the knee below and suppress the knee from opening outward and facilitate the ankle bending operation. As a result, it is possible to carry a clean leg and to realize a smooth walking motion only by walking without the wearer being particularly conscious.

  Here, if the wearing pressure of the support line part 2 is 1.4 times or more and 2.5 times or less of the pressure value of the cylindrical main body, it is possible to more effectively realize clean leg transportation.

Also, support line section 2, as shown in FIG. 5, the reference point position corresponding to the center portion Q of the popliteal of the wearer and are arranged symmetrically in the vertical direction L _Q, the vertical direction (of the wearer Since the support line part 2 is evenly arranged in the leg longitudinal direction), the tightening force can be applied in a balanced manner at the upper part and the lower part of the knee part, and the leg transport can be shown cleanly. In addition, as long as at least a part of the support line portion 2 passes through the central portion of the popliteal Q, it does not have to be vertically symmetrical about the popliteal Q.

  In addition, the inclination angle θ of the support line portion 2 with respect to the width direction W that is a direction intersecting the longitudinal direction of the wearer's leg is preferably 25 degrees or more and 50 degrees or less in a flat state, and the inclination angle θ is More preferably, the angle is 30 degrees or more and 45 degrees or less.

  A long type legging 10 according to an embodiment of the present invention was created and performance evaluation was performed. Evaluation was performed by having women's monitors in their 30s to 40s wear leggings 10 and walk. When the leggings were not worn, when the spats 10 according to the example were worn, when the leggings according to the comparative example not provided with the support line part 2 were worn, the comparison was performed. The change in the position of the knee was measured by taking a picture of a walking with a marker attached to the knee, and acquiring marker locus data by image analysis.

  FIG. 7 is a diagram showing an example of the result of performance evaluation, and shows the change in the position of the knee during walking from the front side. FIG. 7A shows a change in the position of the knee when not wearing the spats, and FIG. 7B shows a change in the position of the knee when wearing the spats according to the embodiment. (C) has shown the positional change of the knee part at the time of wearing the spats which concern on a comparative example.

  In the case shown in FIG. 7 (a), the knee part opened to the outside during walking, and the position of the knee part was shaken in the left-right direction. The range of knee positions was relatively wide. In the case shown in FIG. 7B, the opening of the knee during walking is suppressed, and the lateral movement of the position of the knee is reduced. The range of lateral blur of the knee position was about 1/3 compared to the case shown in FIG. In the case shown in FIG. 7C, the lateral movement of the position of the knee portion is larger than in the case shown in FIG. In the case shown in FIG. 7C, the range of lateral blur of the knee position is about twice that in the case shown in FIG. 7B.

  As a result of the performance evaluation, it was found that in Example 1, 6 out of 8 monitors had the effect of suppressing knee shake during walking. In the spats of the example, the knees did not face outward, and the movement locus of the knee during walking was less blurred. Accordingly, it has been found that the knee is not opened and the leg transport is corrected straight. In addition, there was no difference between the examples and comparative examples for the monitor in which the thigh was originally inward and the knee was not opened during walking. No adverse effects were observed when wearing the spats of the examples.

Moreover, it evaluated about the feeling of wear at the time of wearing the spats 10 which concern on an Example.

  Thus, according to the leggings according to the embodiment of the present invention, it is possible to easily point the knee inward comfortably without the wearer being particularly conscious, and to straighten the leg transport during walking, You can make your legs look beautiful.

  Moreover, according to the monitor, there was an evaluation that it was difficult to open the knee when sitting. That is, it has been found that there is an effect that it is easy to maintain a posture in which the knee is closed when sitting.
