Description

  The present invention relates to pants.

Conventionally known pants include those described in Patent Document 1 below. The pants described in this document can be worn with peace of mind even for wheelchair users, etc., without causing a stitched portion in the buttock-corresponding portion and generating elasticity in the buttock-corresponding portion. It has been proposed. Such pants are produced by combining a large number of cutting parts having shapes designed appropriately in order to realize a desired function and a three-dimensional shape at the time of wearing. Even in normal pants that do not have such special functions, as shown in the example of FIG. 23, the right front body (FIG. 23 (a)), the left front body (FIG. 23 (b)), the left rear Usually, the body is made from four parts such as the body (FIG. 23 (c)) and the right front body (FIG. 23 (d)).
JP 2007-56384 A

  However, as the number of parts related to the production of the pants increases, the number of parts to be cut and sewn increases and the manufacturing cost increases. Therefore, in producing such a pant, it is preferable to reduce the number of parts. Ultimately, it is desirable to create the body of the pants from a single part, but if such a part is designed easily, the left and right widths of the part will increase, and a wide special fabric will be prepared. It may be necessary to do this, and it may be expensive. In this case, if the left and right widths of the parts are to be suppressed, it is difficult to design to fit the three-dimensional shape of the lower body of the human body, resulting in a pant that is not comfortable to wear. Thus, when it is going to produce the body of a pants with one part, it was difficult to make the suppression of the right-and-left width of a part compatible with comfort.

  Therefore, an object of the present invention is to provide a pant with a body that is made using one part with a narrow width and that is comfortable to wear.

The pants of the present invention have a body that is produced by sewing a single cut fabric formed symmetrically with respect to a center line that extends in the longitudinal direction and corresponds to the center of the front waist of the wearer,
The cut fabric is
A pair of left and right crotch right side cutting lines and crotch left side cutting lines that are located at both ends of the upper part and extend downward while curving outward;
A right crotch outer cutting line extending downward from a right end point of the crotch right side cutting line, and a left crotch outer cutting line extending downward from a left end point of the crotch left side cutting line;
A right crotch inner cutting line and a left crotch inner cutting line, which are provided in a pair of left and right between the right crotch outer cutting line and the left crotch outer cutting line, and connected on the center line;
A right hem cutting line connecting the lower end of the right crotch outer cutting line and the lower end of the right crotch inner cutting line;
A left hem cutting line connecting the lower end of the left crotch outer cutting line and the lower end of the left crotch inner cutting line;
Have
The body is
A crotch seam formed by stitching a crotch right side cutting line and a crotch left side cutting line;
A right crotch seam formed by stitching a right crotch outer cutting line and a right crotch inner cutting line;
A left crotch seam formed by stitching a left crotch outer cutting line and a left crotch inner cutting line;
A right leg body part that is formed from a region surrounded by a right crotch inner cutting line, a right crotch outer cutting line, and a right hem cutting line of the cut fabric, and covers a wearer's right leg;
The left leg body part which is formed from the part of the region surrounded by the left crotch inner cutting line, the left crotch outer cutting line and the left hem cutting line of the cut fabric, and covers the wearer's left leg,
Have
The crotch right crotch line of the cut fabric extends in a J-shaped curve, and the tangent at the right end point of the crotch right cut line has an upward slope,
The crotch crotch left side cutting line extends curvedly in a J-shape, and the tangent at the left end point of the crotch left side cutting line has an upward slope,
The lower side of the right crotch outer cutting line and the lower side of the left crotch outer cutting line of the cut fabric extend substantially parallel to the center line.

  The body of the pants is made by sewing a cut fabric. The cut fabric is formed by cutting one sheet, and a pair of left and right crotch right side cutting lines and a crotch left side cutting line extending downward while being curved outward are formed at both upper ends. And this crotch right side cutting line and crotch left side cutting line are sewn, and the crotch seam of the body is formed. Here, since the crotch right side cutting line and the crotch left side cutting line of the cut fabric are curved in a J-shape, it is a three-dimensional shape along the crotch line of the human body and occupies more than half of the crotch line of the human body. Forms relatively long crotch seams. Then, by extending a part of the cut fabric to the left and right so as to form a relatively long crotch seam as described above, the width of the entire cut fabric can be suppressed. Further, by extending a part of the cut fabric from side to side, a comfortable body suitable for the three-dimensional shape of the lower body of the human body is produced using the single cut fabric. The “pants” of the present invention is a general term for clothing worn on the lower body, and includes, for example, pantalons, trousers, slacks, jeans, and the like.

  Further, in the pants of the present invention, the lower side of the right crotch outer cutting line and the lower side of the left crotch outer cutting line of the cut fabric extend substantially parallel to the direction of the center line. Since the corresponding part on the cut fabric does not spread left and right, the left and right width of the entire cut fabric can be further suppressed.

  In addition, the right-side take-out part formed with the upper side of the right crotch outer cutting line of the cut fabric and the lower side of the crotch right cutting line as an outline, the upper side of the left crotch outer cutting line of the cut fabric, and the crotch left cutting line The left-side take-out part formed with the lower side as an outline may correspond to the inner thighs of the wearer's legs.

  In this way, by extending the right and left side take-out portions appearing at both ends of the cut fabric to positions corresponding to the inner leg portions of the wearer's legs, a comfortable body corresponding to the three-dimensional shape of the lower body of the human body can be obtained. As well as shaping, the entire width of the cut fabric can be reduced.

  The upper side of the right crotch outer cutting line and the upper side of the left crotch outer cutting line of the cut fabric may be curved in an S shape.

Further, in this case, the right crotch seam and the left crotch seam of the body are connected at a position visible from the front direction of the wearer,
The crotch seam may intersect the connected right crotch seam and left crotch seam in a T shape.

  ADVANTAGE OF THE INVENTION According to this invention, the body can be produced using one part which suppressed the width | variety narrowly, and the comfortable pants can be provided.

  Hereinafter, preferred embodiments of the pants according to the present invention will be described in detail with reference to the drawings.

(First embodiment)
The body 31 of the trouser 10 shown in FIG.1 and FIG.2 is produced using one part of the cut | disconnected cloth 1 (FIG. 3) cut one sheet. In the body 31, the portion 10 a that covers the center of the rear waist of the wearer of the trouser 10 is continuously cut, and no vertical seam appears in the portion.

  FIG. 3 is a plan view of the cut fabric 1 as viewed from the front side, that is, the front side of the paper surface of FIG. 3 corresponds to the front side of the body 31 of the completed trouser 10. Further, the vertical direction of FIG. 3 coincides with the longitudinal direction (warp direction) A of the cut fabric 1.

  As shown in FIG. 3, the cut fabric 1 is a flat material cut from a fabric having a thickness of about 2 to 3 mm, and extends in the vertical direction A so as to use the vertical position in the vertical direction of the trousers 10. The center line Z is symmetrical with respect to the left and right lines. The cut fabric 1 includes a waistline cutting line 3, a crotch right cutting line R4, a crotch left cutting line L4, a right crotch outer cutting line R5, a left crotch outer cutting line L5, a right crotch inner cutting line R6, and a left crotch inner side. It is cut along nine cutting lines such as a cutting line L6, a right hem cutting line R7, and a left hem cutting line L7 to form a flat shape. Since the cut fabric 1 is cut along the above-mentioned cut lines by a slightly parallel line (indicated by a one-dot chain line in the drawing), the cut fabric 1 is cut out from the fabric. A seam allowance 9 having a predetermined width is provided.

  The waistline cutting line 3 that forms the uppermost contour of the cut fabric 1 extends in a direction substantially perpendicular to the longitudinal direction A, and the completed body 31 forms an opening edge around the waist. A dart 3 a for adjusting the three-dimensional shape of the completed body 31 is formed at two places on the waist cutting line 3.

  The crotch right side cutting line R4 extends downward from the right end point R13 of the waist cutting line 3. The crotch right side cutting line R4 includes an upper line R4a extending linearly from the right end point R13 to the point R4c diagonally downward to the right, and a lower line R4b extending while curving from the point R4c continuously to the upper line R4a. It consists of. The lower line R4b is curved so as to rise upward as it goes to the right, and the tangent line R14a at the right end point R14 has an upward slope. In this way, the crotch right side cutting line R4 has a shape curved in a J shape as a whole.

  The right crotch outer cutting line R5 extends downward from the right end point R14 of the crotch right cutting line R4. The right crotch outer cutting line R5 extends linearly from the upper line R5a extending from the right end point R14 to the point R5c while being curved outwardly convex U-shaped, and from the point R5c following the upper line R5a. It consists of lower line R5b. Among these, the lower line R5b extends substantially parallel to the center line Z. At the right end point R14, the tangent line R14a of the crotch right side cutting line R4 and the tangent line R15a of the right crotch outer side cutting line R5 intersect at a substantially right angle.

  By such a cutting line, at the right end of the cut fabric 1, a line connecting the lower line R4b of the above-mentioned crotch right cutting line R4, the upper line R5a of the right crotch outer cutting line R5, and the points R4c and R5c. And a right-hand side take-out portion R21 having an outline. And this right-hand side taking-out part R21 which shows the shape which turned up and down the wrinkles of the wrinkles will greatly project outside in the right part of the cutting cloth 1. FIG.

  The right crotch inner cutting line R6 located inside the cutting lines R4 and R5 includes a curved upper line R6a and a linear lower line R6b. The upper line R6a extends diagonally downward to the right to the point R6c while curving downward from the center point C of the lower end of the cut fabric 1 on the center line Z, and the lower line R6b is the upper line R6a. It continues from below and extends from the point R6c substantially parallel to the center line Z. The region sandwiched between the right crotch inner cutting line R6 and the right crotch outer cutting line R5 corresponds to the right leg body covering the wearer's right leg in the completed body body 31. The right crotch inner cutting line R6 is connected to the left crotch inner cutting line L6 at the center point C, and the center line Z is defined by the right crotch inner cutting line R6 and the left crotch inner cutting line L6 that are symmetrical to each other. An arch-shaped cut 23 is formed on the top.

  Further, the right hem cutting line R7 is formed as a straight line going up to the right connecting the lower end point R15 of the right crotch outer cutting line R5 and the lower end point R16 of the right crotch inner cutting line R6. The right hem cutting line R7 forms an opening edge of the right leg hem at the lower end of the completed body 31.

  In addition, each site | part symmetrical with respect to each above-mentioned site | part also appears on the left side of the center line Z of this cutting | disconnecting fabric 1. FIG. For example, the crotch left side cutting line L4, the left crotch outer side cutting line L5, and the left crotch inner side cutting line L6 shown in the figure are respectively the crotch right side cutting line R4, the right crotch outer side cutting line R5, and the right crotch side. A symmetrical shape is formed with respect to the inner cutting line R6. Accordingly, for each part on the left side of the center line Z, a reference numeral in which “R” of the corresponding part on the right side is replaced with “L” is attached in the drawing, and detailed description is omitted.

  Next, with reference to FIGS. 1 to 3, the body 31 completed by sewing such a cut fabric 1 will be described. The right leg crotch seam R25 of the body 31 is formed by stitching the right crotch outer cutting line R5 and the right crotch inner cutting line R6 of the cut fabric 1. Similarly, the left leg crotch seam L25 of the body 31 is formed by sewing the left crotch outer cutting line L5 and the left crotch inner cutting line L6 of the cut fabric 1.

  Further, the crotch seam 24 of the body 31 is formed by sewing the crotch right side cutting line R4 and the crotch left side cutting line L4 of the cut fabric 1. At this time, the right end point R14 and the left end point L14 overlap at the center point C on the cut fabric 1. Then, a T-shaped intersection 27 of the connected right leg crotch seam R25 and left leg crotch seam L25, and the crotch seam 24 appears on the back side of the completed body 31. Thereafter, the finished body 31 is processed to form the front pockets 32a and 32b, the rear pockets 33a and 33b, the belt loop 34, the fastener 35, and the like, and the trouser 10 is completed.

  As described above, the crotch right side cutting line R4 and the crotch left side cutting line L4 are J-shaped, so that the completed body 31 wraps around from the wearer's abdomen to the lower part of the buttocks and is half of the crotch line. A J-shaped crotch seam 24 that occupies the above is formed, and the T-shaped intersection 27 appears at a position biased toward the back side as seen from the back side of the wearer. The right and left carry-out portions R21 and L21 of the cut fabric 1 are spread below the crotch seam 24 so as to cover from the wearer's inner thigh to the lower part of the buttock in the completed body 31. Further, in the cut body 1, the lower lines R5b and L5b, which are substantially parallel to the longitudinal direction A, in the completed body 31, respectively, have a right leg crotch seam R25 extending in a direction inclined with respect to the wearer's leg. A left leg crotch seam L25 is formed.

  Thus, in the completed body 31, the part covering the inner thigh of the wearer extends to a position where it can be seen from the back side of the wearer, and the part is greatly extended to the left and right of the cut fabric 1. It is supposed to be formed by take-out portions R21 and L21. With such a configuration, it is possible to realize a three-dimensional body 31 that is comfortable to fit to the lower body shape of the human body without greatly increasing the lateral width of the entire cut fabric 1.

  Further, in the completed body 31, when the right leg crotch seam R25 and the left leg crotch seam L25 are intended to be parallel to the wearer's leg, in the cut fabric 1, the right crotch outer cutting line R5 and the left crotch outer cutting line L5. However, it becomes the shape which spreads outside, so that it goes below, and the right-and-left width of the cutting cloth 1 will spread. Therefore, in the cut fabric 1, as described above, the lower leg lines R5b and L5b are formed on the cut fabric 1 by inclining the right leg crotch seam R25 and the left leg crotch seam L25 with respect to the wearer's leg. It is substantially parallel to the center line Z. With this configuration, the left and right leg bodies can be formed while the lateral width of the cut fabric 1 is suppressed. In this case, since the right hem cutting line R7 and the left hem cutting line L7 are inclined to the right and the left, respectively, on the cut fabric 1, the opening edge of the hem is substantially horizontal in the completed body 31. become.

  In addition, among the mass-produced fabrics, the widest fabric is generally one having a fabric width of about 150 cm called “double width”. According to the above-described configuration of the cut fabric 1, the left and right widths of the cut fabric 1 including the seam allowance can be suppressed to a double width or less while the cut fabric 1 is formed by cutting one sheet. Production becomes possible. And since the body 31 of the trousers 10 is produced from the said cut | judging cloth 1 formed by cutting one piece, the cutting | judging and sewing locations of cloth | dough can be suppressed few and the manufacturing cost of the trousers 10 can be held down.

  It is also conceivable that the fabric width is not limited by designing the cut fabric so that the vertical direction of the pants is orthogonal to the longitudinal direction A. However, such a design is contrary to the basics of clothing design, in which the vertical fabric is used in the vertical direction of the clothing. There is a problem that the mechanical strength decreases. Therefore, it is preferable that the center line Z coincides with the longitudinal direction A as in the cut fabric 1, and for that purpose, it is important to keep the left and right width of the cut fabric 1 narrow.

(Second Embodiment)
The body 131 of the trousers 110 shown in FIGS. 4 and 5 is manufactured using one part of the cut fabric 101 (FIG. 6) cut into one piece. In the body 131, the portion 110a covering the center of the front waist of the wearer of the trousers 110 is continuously cut, and no vertical seam appears in the portion. The body 131 is formed approximately symmetrically in the front-rear direction compared to the body 31 described above, but the front and rear asymmetry in the lower half of the human body is reflected, and the shape of each part is different from the body 31.

  FIG. 6 is a plan view of the cut fabric 101 as viewed from the back side, that is, the front side of the paper surface of FIG. 6 corresponds to the back side of the body 131 of the completed trouser 110. Further, the vertical direction in FIG. 6 coincides with the longitudinal direction (warp direction) A of the cut fabric 101.

  As shown in FIG. 6, the cut fabric 101 is a flat shape cut from a cloth having a thickness of about 2 to 3 mm, and extends in the vertical direction A so as to use the vertical position in the vertical direction of the trousers 110. The center line Z is symmetrical with respect to the left and right lines. This cut fabric 101 includes a waist cutting line 103, a crotch right cutting line R104, a crotch left cutting line L104, a right crotch outer cutting line R105, a left crotch outer cutting line L105, a right crotch inner cutting line R106, and a left crotch inner side. Cut along nine cutting lines such as a cutting line L106, a right hem cutting line R107, and a left hem cutting line L107, and formed into a planar shape. Since the cut fabric 101 is cut along the above-mentioned cut lines by a slightly parallel line (indicated by a one-dot chain line in the drawing), the cut fabric 101 is cut out from the fabric. A sewing allowance 109 having a predetermined width is provided.

  The waist cutting line 103 that forms the contour of the uppermost portion of the cut fabric 1 extends in a direction substantially orthogonal to the longitudinal direction A, and the completed body 131 forms an opening edge around the waist. Darts 103 a for adjusting the three-dimensional shape of the completed body 131 are formed at two places on the waist cutting line 103.

  The crotch right side cutting line R104 extends downward from the right end point R113 of the waistline cutting line 103. The crotch right side cutting line R104 includes an upper line R104a extending linearly from the right end point R113 to a point R104c diagonally downward to the right, and a lower line extending while curving from the point R104c continuously to the upper line R104a. R104b. The lower line R104b is curved so as to be lifted upward as it goes to the right, and the tangent line R114a at the right end point R114 has an upward slope. Thus, the crotch right side cutting line R104 has a shape curved in a J shape as a whole.

  The right crotch outer cutting line R105 extends downward from the right end point R114 of the crotch right cutting line R104. The right crotch outer cutting line R105 is curved in an S shape and extends from the right end point R114 to the point R105c diagonally to the lower left, and linearly from the point R105c following the upper line R105a. The lower line R105b extends. Among these, the lower line R105b extends substantially parallel to the center line Z. At the right end point R114, the tangent line R114a of the crotch right side cutting line R104 and the tangent line R115a of the right crotch outer side cutting line R105 intersect at a substantially right angle.

  By such a cutting line, at the right end of the cut fabric 101, the lower line R104b of the crotch right cutting line R104, the upper line R105a of the right crotch outer cutting line R105, and the line connecting the point R104c and the point R105c. And a right-hand carry-out portion R121 having the outline as a contour. And this right-hand side taking-out part R121 which shows the shape which turned up and down the wrinkles of the wrinkles greatly projects outside in the right part of the cutting fabric 101. The right side take-out portion R121 is smaller than the right side take-out portion R21 of the cut fabric 1, but this difference reflects the difference in the three-dimensional shape between the front side and the rear side of the lower half of the human body.

  The right crotch inner cutting line R106 located inside the cutting lines R104, R105 is composed of a curved upper line R106a and a linear lower line R106b. The upper line R106a extends diagonally downward to the right to the point R106c while curving downward from the center point C of the lower end of the cut fabric 101 on the centerline Z, and the lower line R106b It continues from below and extends from the point R106c substantially parallel to the center line Z. A region sandwiched between the right crotch inner cutting line R106 and the right crotch outer cutting line R105 corresponds to the right leg body covering the wearer's right leg in the completed body body 31. The right crotch inner cutting line R106 is connected to the left crotch inner cutting line L106 at the center point C, and the center line Z is defined by the right crotch inner cutting line R106 and the left crotch inner cutting line L106 that are symmetrical to each other. An arch-shaped cut 123 is formed on the top.

  The right hem cutting line R107 is formed as a straight line connecting the lower end point R115 of the right crotch outer cutting line R105 and the lower end point R116 of the right crotch inner cutting line R106. The right hem cutting line R107 forms an opening edge of the right leg hem at the lower end in the completed body 131.

  In addition, each part symmetrical to the above-described parts also appears on the left side of the center line Z of the cut fabric 101. For example, the crotch left side cutting line L104, the left crotch outer side cutting line L105, and the left crotch inner side cutting line L106 shown in the figure are respectively the crotch right side cutting line R104, the right crotch outer side cutting line R105, and the right crotch outer side cutting line R105. A symmetrical shape is formed with respect to the inner cutting line R106. Accordingly, for each part on the left side of the center line Z, a reference numeral in which “R” of the corresponding part on the right side is replaced with “L” is attached in the drawing, and detailed description is omitted.

  Next, with reference to FIGS. 4 to 6, a body 131 completed by sewing such a cut fabric 101 will be described. The right leg crotch seam R125 of the body 131 is formed by sewing the right crotch outer cutting line R105 and the right crotch inner cutting line R106 of the cut fabric 101. Similarly, the left leg crotch seam L125 of the body 131 is formed by stitching the left crotch outer cutting line L105 and the left crotch inner cutting line L106 of the cut fabric 101.

  Further, the crotch seam 124 of the body 131 is formed by sewing the crotch right side cutting line R104 and the crotch left side cutting line L104 of the cut fabric 101. At this time, the right end point R114 and the left end point L114 overlap at the center point C on the cut fabric 101. A T-shaped intersection 127 of the connected right leg crotch seam R125, left leg crotch seam L125, and crotch seam 124 appears on the front side of the completed body 31. Thereafter, the finished body 131 is processed to form the front pockets 132a and 132b, the rear pockets 133a and 133b, the belt loop 134, the fastener 135, and the like, thereby completing the trousers 110.

  As described above, since the crotch right side cutting line R104 and the crotch left side cutting line L104 are J-shaped, the completed body 131 wraps around from the wearer's waist to the lower part of the front waist. A J-shaped crotch seam 124 that occupies more than half is formed, and the T-shaped intersection 127 appears at a position deviated toward the front side as seen from the front side of the wearer. Then, the right and left carry-out portions R121 and L121 of the cut fabric 101 are spread below the crotch seam 124 so as to cover from the wearer's inner thigh to the lower part of the front waist in the completed body 131.

  In this way, the portion of the completed body 131 that covers the wearer's inner thigh extends to a position that can be seen from the front side of the wearer, and the portion is greatly extended to the left and right of the cut fabric 101. It is supposed to be formed by the take-out portions R121 and L121. With such a configuration, it is possible to realize a three-dimensional body 131 having a good fit that is adapted to the lower body shape of the human body without significantly increasing the width of the cut fabric 101 as a whole.

  Further, among general fabrics related to mass production, the widest fabric is a fabric having a width of about 150 cm called “double width”. According to the above-described configuration of the cut fabric 101, the left and right widths of the cut fabric 101 including the seam allowance can be suppressed to a double width or less while forming the cut fabric 101 by one sheet. Production becomes possible. And since the body 131 of the trousers 110 is produced from the cut fabric 101 formed by cutting one piece, the number of fabric cutting and sewing locations can be suppressed, and the manufacturing cost of the trousers 110 can be reduced.

  It is also conceivable that the fabric width is not limited by designing the cut fabric so that the vertical direction of the pants is orthogonal to the longitudinal direction A. However, such a design is contrary to the basics of clothing design, in which the vertical fabric is used in the vertical direction of the clothing. There is a problem that the mechanical strength decreases. Therefore, it is preferable that the center line Z coincides with the longitudinal direction A as in the cut fabric 101. For this reason, it is important to keep the left and right width of the cut fabric 101 narrow.

(Third embodiment)
The body of the trousers (pants) 210 shown in FIGS. 7 to 14 uses a cut fabric designed to further fit the three-dimensional shape of the lower body of the human body by adding appropriate darts to the cut fabric 1 described above. It was produced. The trousers 210 are manufactured by processing the body to form a belt loop, a pocket, and the like. 7 to 14 show the shape of the pants 210 when worn. Moreover, in FIGS. 7-14, the part represented with the continuous line is a part which is going to receive design registration as a partial design.

(Fourth embodiment)
The body of the trousers (pants) 310 shown in FIGS. 15 to 22 uses a cut fabric designed to further fit the three-dimensional shape of the lower body of the human body by adding appropriate darts to the cut fabric 101 described above. It was produced. The trousers 310 are manufactured by performing processing for forming a belt loop, a pocket, and the like on the body. 15 to 22 show the shape of the pants 310 when worn. In FIGS. 15 to 22, the part indicated by a solid line is a part that is about to undergo design registration as a partial design.
