JP 2001-214303 A (Japanese Patent No. 3740344)

  By the way, it is known that pedaling power (treading force) of a cyclist is improved by pedaling so as to fully use the muscle strength of the greater ankle muscle (large buttocks) or the thigh muscle. However, the conventional exercise garment does not have a configuration for assisting the exertion of the muscle strength of the greater gluteus or thigh muscles, and therefore it cannot be expected to improve pedaling power.

  SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to provide a cycling pant that can improve the pedaling power by assisting the functions of the greater gluteal and thigh muscles.

The present invention is a cycling pant made of an elastic fabric for a cyclist to wear when riding a bicycle, and includes a pad portion for protecting the cyclist's crotch, from the great gluteal muscle of the cyclist to the biceps femoris. Over a corresponding region, a sheet-like high-elasticity fabric having a lower expansion / contraction ratio in the surface direction than the other parts is provided, and a part of the high-elasticity fabric includes a side part of the pad part and other parts. The pad portion is sewn at a position where the portion is divided. Further, the high elastic fabric, and the side along the widthwise direction, and the side along the length direction, and a side for continuous and height direction upper end of the side along the width direction inside end and height direction of the side along the width direction It is possible to adopt a configuration that is provided in a planar shape.

  In the above configuration, the highly elastic fabric stretches in the surface direction in accordance with the volume expansion of the greater gluteal and biceps femoris during the cyclist's pedaling operation, and the stretched high elastic fabric has a higher elasticity in the contracting direction. Since a large amount of energy is accumulated, the energy is released when the highly elastic fabric contracts in the plane direction along with the volume contraction of the greater gluteus and biceps femoris associated with the cyclist pedaling movement, It is possible to sufficiently assist (assist) volume contraction of the greater gluteus and biceps femoris.

  In the cycling pants according to the present invention, the cyclist is provided with a highly elastic fabric having a lower expansion / contraction ratio in the surface direction than the other portions over a region corresponding to the biceps femoris muscle of the cyclist. The high elastic fabric stretched in the plane direction in response to the volume expansion of the greater gluteus and biceps femoris during pedaling movements of the cyclist is in a state where a large amount of energy is accumulated in the contraction direction due to the high elasticity, pedaling of the cyclist The energy is released when the highly elastic fabric contracts in the surface direction along with the volume contraction of the greater gluteus and the biceps femoris as it moves, and it sufficiently assists in the volume contraction of the greater calf muscle and the biceps femoris By doing so, the pedaling power can be improved.

It is a front view of cycling pants showing one embodiment of the present invention. It is a rear view of the cycling pants. It is a side view of the cycling pants. It is a rear view which shows the relationship between the leg muscles in the wearing state of the cycling pants, and the highly elastic fabric. It is typical explanatory drawing of the expansion-contraction state of the same highly elastic fabric, (a) is a schematic diagram when there is no expansion / contraction standard, (b) is a schematic diagram when the expansion / contraction standard is assumed. It is a side view showing the pedaling operation | movement of the same cyclist. It is a perspective view of the posture where the same cyclist is bending the knee greatly (the posture in which the pedal is depressed with the right foot). FIG. 8 is a perspective view of a posture in which the right foot is further rotated from the posture of FIG. 7 (a posture in which the right foot is being returned). It is a related figure of the rotation angle of the pedal and the muscle used.

  Hereinafter, based on FIG. 1 thru | or FIG. 9, the cycling pants which concern on one Embodiment of this invention are demonstrated. The cycling pants 10 are pants worn by a cyclist (passenger) H when boarding a bicycle B mainly for sports running such as road racers and mountain bikes. The cycling pants 10 are formed of a cloth that the cyclist H wears and the cyclist H performs some motion to change the shape of the muscles and the like, so that the cyclist H stretches along the body surface of the cyclist H along with the motion. Yes. That is, the direction along the body surface of the cyclist H corresponds to the surface direction of the stretchable fabric constituting the cycling pants 10.

  As shown in FIGS. 1 to 4, the cycling pant 10 has a pant body 12 and a pair of left and right shoulder straps 14 fixed to the pant body 12. The pants body 12 is made of a stretchable fabric such as polyester. 1 to 3 are illustrated in a state in which the dough is not stretched, that is, not attached to the cyclist H. FIG. 4 is drawn with the cyclist H attached.

  The pant body 12 includes a front waist portion 20, a rear waist portion 22 that forms a waist opening 26 that covers the upper body of the cyclist H together with the front waist portion 20, and a crotch portion 24 positioned between a pair of leg openings 28. have.

  The front waist portion 20 is made of a perforated mesh material in which a large number of easily visible holes are formed. The front waist portion 20 is formed of a front upper portion 20c formed in a U-shape when viewed from the front, and a material without holes. And a front lower portion 20 d that continues to the crotch portion 24. The front lower part 20d extends to the edge part on both sides.

  The rear waist portion 22 is integrally formed with the pair of shoulder strap portions 14. The rear waist portion 22 is formed of a perforated mesh material formed of a perforated mesh material in which a shoulder strap portion 14 is connected to form a number of easily visible holes, and a crotch portion 24 formed of a material without holes. And a rear lower portion 22b.

  The rear upper portion 22a is formed to project in a U shape toward the rear lower portion 22b. The rear lower part 22b also extends to the edge part at the side as in the front lower part 20d. And the connection part of the front waist part 20 and the back waist part 22 is greatly pierced by the U shape at both sides.

  The pair of shoulder strap portions 14 extends from the rear waist portion 22 of the pant body 12 to the front waist portion 20 via both shoulders of the cyclist H. The shoulder strap portion 14 is made of a perforated mesh material in which a number of easily visible holes are formed, and is integrated with the same fabric as the front upper portion 20c of the front waist portion 20 and the rear upper portion 22a of the rear waist portion 22. Is formed.

  The crotch portion 24 is located between the pair of leg openings 28 and is formed so as to cover the thigh H2 and the crotch H3 of the cyclist H. The crotch portion 24 is sewn from the front and rear waist portions 20 and 22 so that the leg opening 28 is slightly forward. In the crotch portion 24, a pad portion P that protects the crotch H <b> 3 of the cyclist H is provided in a region corresponding to the crotch H <b> 3 of the cyclist H (intermediate portion of both hems). The pad portion P is provided in the crotch portion 24 so as to extend before and after the crotch H3, and a cushioning material (not shown) for protecting the crotch H3 of the cyclist H from friction with the saddle S of the bicycle B is provided on the back of the fabric. It is fixed.

  The back of the crotch portion 24 is constituted by a buttock fabric 23 sewn on the lower side of the rear lower portion 22b. Below the crotch portion 24 is constituted by a hem fabric 25 forming a leg opening 28 (located on the cyclist H's knee when the cycling pants 10 are worn). The heel fabric 23 is sewn with the skirt fabric 25. In particular, since the hem fabric 25 is formed of a knitted fabric, it is possible to maintain a favorable wearing feeling when the cyclist H wears the cycling pants 10, rides on the bicycle B and rotates the pedal 33. It is like that.

  As shown in FIGS. 2 to 4, a part of the buttock fabric 23 of the crotch part 24 extends from the greater gluteal muscle M1 of the cyclist H to the region corresponding to the biceps femoris (part of the hamstring) M2. It is comprised from the highly elastic fabric 27 with a low expansion-contraction rate compared with this part. Since the highly elastic fabric 27 has a lower expansion / contraction rate than other portions of the fabric, the contraction force in the stretched state is stronger than that of the other portions. The highly elastic fabric 27 is distributed and arranged on the left and right of the buttocks fabric 23 so as to correspond to a part of the biceps femoris M2 from the greater left and right greater gluteal muscles M1 of the cyclist H. Since each high-elasticity fabric 27 is used symmetrically, the shape of the high-elasticity fabric 27 on the right side as viewed from the back is described, and is also used for the description of the shape of the high-elasticity fabric 27 on the left side.

  FIG. 5 is a single view of the right high-elasticity fabric 27 in a state where it is not yet sewn as a part of the buttock fabric 23. In the figure, the X direction is the width direction (left-right direction), and the Y direction is the length direction (up-down direction). The highly elastic fabric 27 can expand and contract in the X direction and the Y direction, and can also expand and contract in directions including the X direction component and the Y direction component. In FIG. 5, the solid line indicates a state where the force in the expansion / contraction direction is not received, and the imaginary line indicates a state where the cyclist H is extended to the maximum by the pedaling operation.

  The highly elastic fabric 27 is formed in a substantially triangular shape by a lower end side 30, a right end side 31 and a curved side 32. The lower end side 30 is formed linearly along the width direction of the highly elastic fabric 27, the right end side 31 is formed linearly along the length direction, and the curved side 32 is the inner end of the lower end side 30. (Left end) and the upper end of the right end side 31 are formed in a shape that protrudes inward in the width direction. The interior angle of one vertex of the triangle that is the intersection of the right end side 31 and the curved side 32 is formed to be an acute angle.

  Returning to FIG. 2 to FIG. 4, in such a state that such a high-elasticity fabric 27 is used as a part of the heel fabric 23, the curved side 32 divides the side portion of the pad portion P (rear pad portion). The apex of the triangle that is the intersection of the right end side 31 and the curved side 32 is positioned at the boundary between the rear lower portion 22b and the buttock fabric 23, and the lower end side 30 of the highly elastic fabric 27 is the hem fabric. Is set to match 25.

  When the cycling pants 10 having such a structure are worn, the shoulder straps 14 are hung on both shoulders after the pants body 12 is worn with both legs passing through the leg openings 28 of the pant body 12. To do. Since the entire pant body 12 is formed of a stretchable fabric, the buttocks fabric 23 fits the cyclist H's buttocks and the back of the thighs.

  As a result of pedaling by mounting the cycling pants 10 on the bicycle B with the cyclist H wearing it, it has been physically confirmed that pedaling power has been improved. Furthermore, as will be described later, in the highly elastic fabric 27 during pedaling, the maximum elongation in the circumferential direction of the buttocks (corresponding to the lateral direction in FIG. 5) and the length direction in a state of covering the buttocks and the biceps femoris In the maximum elongation rate (corresponding to the vertical direction in FIG. 5), it was found that the circumferential elongation rate exceeded the lengthwise elongation rate.

  Here, when the cyclist H wears the cycling pants 10 and rides on the bicycle B, the pad portion P comes on the saddle S, so that the highly elastic fabric 27 divides the side portion of the pad portion P. Assuming the case where stretching is performed based on a partial region of the curved side 32 being sewn, the stretching mode of the highly elastic fabric 27 accompanying the pedaling operation will be described with reference to FIG.

  The cyclist H is considered to have the most scenes of pedaling while sitting on the saddle S. Assuming that the pad portion P is fixed to the saddle S when sitting on the saddle S, the highly elastic fabric 27 is sewn so that the curved side 32 divides the side portion of the pad portion P. The high-elasticity fabric 27 is considered to expand and contract in the surface direction using the sewing portion as the expansion / contraction reference 32a. That is, in a schematic diagram as shown in the figure, the film expands and contracts in the surface direction with respect to the reference 32 a in the middle of the curved side 32. In the high-elasticity fabric 27 during pedaling, the maximum elongation rate in the circumferential direction of the buttocks and the maximum elongation rate in the length direction in the state of covering the buttocks and the biceps femoris are specifically described in the circumferential direction. The maximum elongation was about 30%, and the maximum elongation in the length direction was about 10%.

  By the way, as shown in FIGS. 6 to 8, in the cyclist H, when pedaling (rotating motion) for riding the bicycle B and rotating the pedal 33 of the bicycle B by 360 ° (rotational motion), the greater ankle, biceps, and crus It is known that pedaling power is improved when the head muscle, anterior tibial muscle, semi-tendonoid muscle, semi-membranous muscle, iliopsoas muscle, and the like are utilized in accordance with the rotation angle of the pedal 33.

  Further, before the pedal 33 is depressed (refer to FIG. 9, for example, a posture in which the knee is largely bent in a pedaling region of 12:00 to 2 o'clock or 11:00 to 3 o'clock), It is deformed so as to expand in volume outward with respect to the surrounding direction (the length in the length direction shrinks as a whole). And this pedaling area | region is the range where the contraction activity of the greater aneurysm M1 is thriving. On the other hand, for example, in the vicinity of the pedaling region from 2 o'clock to 8 o'clock, or from 3 o'clock to 9 o'clock, the greater calf muscle M1 is deformed so as to expand (the muscle in the expanded state contracts).

  If the greater gluteal muscle M1 is volume-expanded outwardly around the heel of the cyclist H, the highly elastic fabric 27 covering a part of the region corresponding to the greater gluteal muscle M1 follows the periphery of the buttock according to the volume expansion. It will extend in the surface direction. In other words, the highly elastic fabric 27 is in a state where a large stress (energy in the shrinking direction) is generated with respect to expansion in the surface direction corresponding to the elasticity. It should be noted that the fabric other than the highly elastic fabric 27 also extends in the surface direction around the heel portion.

  That is, when the greater gluteal muscle M1 is extended by the pedaling operation, it is assisted by the stress of the highly elastic fabric 27 extending in the plane direction in advance (energy in the contraction direction is released). For this reason, the greater gluteal muscle M1 becomes easier to extend. This is thought to improve pedaling power.

  In particular, the biceps femoris M2 is a part where force is continuously inherited from the greater gluteus M1, as shown in FIG. In the cycling pants 10, the highly elastic fabric 27 also covers a part of the biceps femoris M2, so that the biceps femoris M2 (a part of the hamstrings) contracts in the length direction. For this reason, it is thought that pedaling power improves.

  In short, in the cycling pants 10 of the present embodiment, the high elastic fabric 27 provides assistance for contraction of the greater gluteal muscle M1 in addition to assistance for contraction of the biceps femoris M2, thereby significantly improving pedaling power. it can.

  The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the gist of the present invention. In addition, the specific configuration of each part is not limited to the above embodiment. For example, in the above embodiment, the high-elasticity fabric is applied to the areas corresponding to the greater gluteal muscle and the biceps femoris, but by applying to the areas corresponding to the semi-tendon-like muscle and the semi-membranous muscle, It can also be configured to assist movement.
