Description

  The present invention relates to trousers partially made of stretchable fabric.

  Conventionally, light work such as office work in the company (for example, work exclusively for desk work, work of supermarket clerk, work of home appliance mass sales clerk, work of waiter, work of cook, work of hall staff of pachinko parlor, cleaning Employees, etc., work in pants (slacks, trousers, pants).

  The main operations in light work include writing while sitting in a chair, cleaning while keeping a squatting posture, displaying products, cooking while keeping standing, Can give explanations.

  In order to improve the working environment of employees and the like in a better direction, the result of taking a questionnaire to conventional pants wearers is shown in FIG.

  The company seeks to contribute to the company PR, to be elegant, to have collective beauty, to be friendly, and to move easily. The wearer side (employee side) seeks to be easy to move, elegant, fashionable, and have a bright image.

  According to the above questionnaire results, except for contributing to company PR, pants are required to be easy to move (comfort), elegant, and have a beautiful appearance such as having group beauty. I understand. Furthermore, although it does not appear in the questionnaire, safety is a matter of course, and it is hard to get tired (comfort; for example, when the wearer squats down, the back does not come out or the abdomen is not compressed and back pain occurs. Do not do).

  On the other hand, heavy work (for example, work that greatly deforms the body such as assembly and repair of machines, work of mechanics such as racing drivers, automobiles, work of firefighters, rescue workers, precision machine manufacturers, garbage disposal companies, influenza Immunizers, work of people engaged in agriculture, dairy farming) are known to be used to wear elastic materials on the waist, making the wearer easy to move (for example, , See Patent Document 1 and Patent Document 2).

  Major operations in heavy work may include driving while maintaining a sitting state, maintenance, manufacturing, transportation, and rescue operations that repeatedly repeat walking, standing, and sitting, etc. it can.

  The jumpsuit is required to be easy to move (comfort) against intense exercise, and to protect the body from dirt, dust, injury, flame, bacteria, etc. (safety).

  By the way, when wearing conventional trousers and doing light work such as office work, the clothing pressure increases due to the movement operation from the upright posture to the sitting position, the turning operation from the sitting position, etc. ) May feel uncomfortable.

  Therefore, it is conceivable that the entire trousers are made of a stretchable material (stretch material) in order to reduce clothes pressure and make it easier for the pants wearer to move during light work.

  However, if the entire trouser is made of a stretch material, pilling (pilling) and snacking will occur, resulting in knee dislodgement (swelling of the knee) and poor appearance. In addition, although it is possible to secure the ease of movement of the wearer by making the entire pants made of stretch material, the current social conventions are elegance, fashionability, contribution to company PR, and friendliness. It is hard to say that they are satisfied with the group beauty. Because of this, light work trousers made entirely of stretch material have hardly been put to practical use.

  Since the conventional jumpsuit described in each of the above patent documents uses a stretch material at the waist, it is easy for the wearer to take a posture of leaning forward.

  In addition, the conventional jumper described in each of the above-mentioned patent documents and other conventional jumpers are work that changes the posture greatly and frequently by bending the body greatly (heavy work; upper body in automobiles, repairs, assembly of machines, etc.) It is formed in the form of a torso, and it is more rugged than the pants for the wearer's body.

  By carrying out heavy work by wearing a jumpsuit that connects the upper garment part and the lower garment part, fine dust and swarf enter the jumper from between the upper garment part and the lower garment part even when the body is pushed in. This prevents the splinter from getting caught in the machine, and spatter does not enter from within the splinter (especially the boundary between the upper garment part and the lower garment part) in a welding operation or the like.

  However, if you wear light clothes described in the above patent document and do light work such as office work, you can easily lean forward, but the upper and lower garment parts are connected and continuous, so the upright posture In a posture where the upper body stands up, such as in a sitting position, almost all of the load of the jumpsuit is applied to the wearer's shoulder. In addition, inconveniences such as difficulty in writing characters and difficulty in operating a keyboard and mouse of a personal computer may occur, and stiff shoulders may occur.

  Also, in the sitting position, the swallow is swung around the hips even though the swallow is sandwiched between the wearer and the chair, and the entire body is dubbed and stretch material is used for the waist. It becomes difficult to move the body, for example, it becomes difficult to move.

  In heavy work, the posture of the body is frequently changed and the arms are moved up and down, so that they lie on their backs or lie on their stomachs. Is avoided. In addition, there is little burden on a minor optic nerve such as writing letters.

  On the other hand, when wearing a jumpsuit, excretion of stool becomes troublesome, and current social conventions satisfy elegance, fashionability, contribution to corporate PR, friendliness, and group beauty. However, it seems difficult to wear jumpsuits for light work such as office work.

  In addition, as understood from the above description, jumpsuits and trousers are the most basic purpose of use as clothing (clothes), that is, use that covers the body of a worker (wearer) and ensures safety. They have the same purpose, but for most other uses, they are different from each other, they are completely different from each other as products and products, and their technical fields are different.

  For example, in the case of jumpsuits, the back does not come out when the wearer squats down, and the abdomen is not compressed and the back pain does not occur, but in pants, the above problems such as the back coming out when the wearer squats down are overcome. There is a need to. Even in view of this point, the jumpsuits and pants are similar to each other.

  The present invention has been made in view of the above-described problems, and is a trouser that is easy to move and that can withstand long-time wearing in a mode in which the changed portion is less noticeable than conventional normal trousers (pants). The purpose is to provide.

  The invention according to claim 1 is a portion corresponding to the waist portion of the wearer, at an area where the upper end edge is joined to the belt cloth and the lower end edge is joined to the back body, and at the fold line extending in the lateral direction.

From the vicinity of the even-numbered folds, the covering cloth is bonded to the stretchable cloth and the stretchable cloth joining portion is formed, and the pants wearer is in a squatting position. Corresponding to the stretch of the wearer's skin, the covering cloth / elastic cloth joining portion, the elastic cloth joined to the belt cloth and the upper edge portion of the covering cloth are joined to the back body. Among the stretchable fabrics and covering cloths, the distance between the parts adjacent to each other is different from each other in the vertical direction.

  The invention according to claim 4 is the trouser according to any one of claims 1 to 3, wherein the crotch inner side edge of the left and right front bodies and the crotch inner side edge of the rear body are joined. In addition, it is configured by joining the crotch outer side edge of the front body and the crotch outer side edge of the rear body, and the position of the crotch inner side edge of the front body and the crotch inner side edge of the rear body, Set at least a position where it is difficult to expand and contract when the legs are opened, shifting to the front side and the rear side, and a buttock on the space between the crotch inner side edge of the front body and the crotch inner side edge of the rear body at the shifted position The height direction dimension of the central part in the front-rear direction of the buttocks is set longer than the height direction dimension of the crotch inner side edge of the front body and the crotch inner side edge of the back body before shifting the position.

  The pants 10 are long pants used for light work such as office work (desk work), for example, and when worn, the wearer's body (the part below the horizontal line at the navel; The lower part of the abdomen and the lower part of the leg including the legs; the lower part of the abdomen including the waist, the thighs and the lower thighs), that is, no contact between the skin of the wearer It is in the form that there is some space if not so. However, for example, at the belt line (the annular part between the belt line and a part slightly lowered from the belt line by, for example, about 10 cm to 20 cm), it is in close contact with the wearer's skin directly or through underwear. It is supposed to be.

  In addition, the trouser 10 is provided with an elastic fabric 201 and a covering fabric 203 as shown in FIG. As shown in FIG. 4 and the like, the stretchable fabric 201 is formed in a rectangular shape, for example, and corresponds to the waist part of the wearer of the trousers 10 (the part corresponding to the upper part of the buttock from the waist part; The sacrum is provided at a width of about 1.5 to 3 times the width of the sacrum.

  The elastic fabric 201 has an upper end edge (the entire length of the upper side extending in the lateral direction or a portion in the vicinity thereof) at the lower end (lower edge or the vicinity thereof) of the annular belt portion 205, and the like. Are integrally joined to a belt cloth (cloth constituting the belt portion 205) 207 (for example, stitched by a seam 209 extending in the lateral direction).

  The trouser 10 is provided with a belt loop 206. In most cases, a wearer of the trouser 10 passes the belt through the belt loop 206 on the outer periphery of the belt portion 205, and the waist with the belt so that the trouser 10 does not fall. Tighten properly and wear trousers 10.

  As shown in FIG. 1, the belt loop 206 is provided, for example, at two locations on the front side of the trouser 10 (for example, a portion immediately below the left and right teats).

  A configuration in which a plurality of belt loops 206 are provided on the front side of the trouser 10 may be provided (not shown). In the configuration in which four belt loops 206 are provided, the two belt loops (front inner belt loops) 206 are located slightly inside the right and left nipples, and the other two belt loops (front outer belt loops) 206 are Located slightly outside the right and left nipples. Further, the front outer belt loop 206 is located above the opening of the front pocket of the trouser 10.

  Further, as shown in FIG. 3, the belt loop 206 is provided on the rear side of the trouser 10 at, for example, two diagonally rear positions and one just rear position. One of the two belt loops obliquely rearward is located above the left end of the stretchable fabric 201 and the covering cloth 203, and the other belt loop 206 is formed of the stretchable cloth 201 and the covering cloth 203. It is located above the right end.

  1 and 3, the width of the belt loop 206 is different. For example, the right belt loop 206 in FIG. 1 is wide, the left belt loop 206 in FIG. 1 is narrow, and the middle belt loop 206 in FIG. 3 is wide. The left and right belt loops 206 are narrow.

  Here, some or all of the belt loops 206 may be changed to a narrow type, and conversely, some or all of the belt loops 206 may be changed to a wide type.

  However, when the middle belt loop 206 in FIG. 3 is changed to a narrow type, it is desirable to use two belt loops 206. That is, it is desirable to delete the middle portion of the middle wide belt loop 206 in FIG. 3 in the left-right direction to form two narrow belt loops.

  Further, as shown in FIG. 3, the trouser 10 is provided with a pair of rear pockets 208 at the left and right buttocks. The rear pocket 208 is, for example, a bead pocket, and is located below the left and right ends of the stretchable fabric 201 and the covering fabric 203.

  That is, in the left-right direction of the trousers 10, the positions of the left rear pocket 208 and the left ends of the stretchable fabric 201 and the covering cloth 203 are substantially coincided with each other, and the center of the right rear pocket 208 is The positions of the elastic fabric 201 and the right end of the covering cloth 203 are substantially coincident with each other.

  In addition, about the width (dimension in the left-right direction) of the back pocket 208, about 1/2 of the width (dimension in the left-right direction) of the stretchable cloth 201 and the covering cloth 203 is slightly smaller than 1/2.

  The stretchable fabric 201 is integrated with the back body 12 in which the lower end edge (the full length of the lower side extending in the lateral direction or a portion in the vicinity thereof) is made of a fabric having almost no stretchability such as a fabric. Are joined together (sewn by a seam 211 extending in the lateral direction).

  The stretchable fabric 201 is made of, for example, a power net fabric. The power net fabric is a fine net-like knitted fabric with stretchability. It is produced by knitting a fiber such as nylon and polyurethane elastic fiber to each other, and is excellent in kickback property when stretched.

  The covering cloth 203 is formed in a rectangular shape whose width dimension (lateral dimension) is substantially equal to that of the stretchable cloth 201 and whose vertical dimension is larger than the vertical dimension of the stretchable cloth 201. The covering cloth 203 is folded back at a fold line 213 extending in the lateral direction (width direction) and formed into a hook shape or bellows shape (becomes pleated). It should be noted that the vertical dimension of the covering cloth in the form of a bowl is substantially equal to the vertical dimension of the stretchable fabric 201.

  The covering cloth 203 is provided on the stretchable fabric 201 so as to overlap the waist portion of the pants 10 wearer. The covering cloth 203 has an upper end edge (the entire length of the upper side extending in the lateral direction or a portion in the vicinity thereof) at the lower end (lower edge or the vicinity thereof) of the annular belt portion 205. The belt unit 205 is integrally joined together with the stretchable fabric 201 (sewn by a seam 209 extending in the lateral direction).

  In the covering cloth 203, the lower end edge (the entire length of the lower side extending in the lateral direction or a portion in the vicinity thereof) is integrally joined to the back body 12 together with the stretchable fabric 201 ( It is sewn with a seam 211 extending in the lateral direction).

  The covering cloth 203 is made of a cloth that hardly stretches, such as a cloth.

  Since the stretchable fabric 201 and the covering cloth 203 are provided as described above, the waist stretchable portion (the portion corresponding to the waist portion of the wearer of the pants 10) is stretched in the vertical direction ( Active ridge) 215 is provided.

  As shown in FIG. 4, one end edge (the left side extending in the vertical direction or a portion in the vicinity thereof) in the horizontal direction (the direction perpendicular to the vertical direction) of the rectangular elastic fabric 201 is the back body 12. Are integrally joined to each other (sewn by a seam 217 extending in the vertical direction). Similarly, the other end edge in the horizontal direction of the stretchable fabric 201 (the right side extending in the vertical direction or a portion in the vicinity thereof) is integrally joined to the back body 12 (extends in the vertical direction). Stitched at the seam 219).

  The first fold 213 (213A) of the covering cloth 203 extends in the lateral direction over the entire width of the covering cloth 203 on the upper side of the covering cloth 203, and the covering cloth 203 is, for example, mountain folded (trousers 10) at the first fold 213A. (Folded as viewed from the outside) and folded back almost 180 ° (see FIG. 5).

  The covering cloth 203 may have a plurality of fold lines 213 formed therein. As a result, the covering cloth 203 may have a plurality of ridges.

  The covering cloth 203 provided with the fold 213 will be described in detail. The second fold 213B of the covering cloth 203 is separated from the first fold 213A by a predetermined distance in the direction away from the upper edge of the covering cloth 203 along the path of the covering cloth 203, and in the lateral direction over the entire width of the covering cloth 203. It extends. At the second eye 213B, the covering cloth 203 is folded back approximately 180 ° by, for example, valley folding (valley folding as viewed from the outside of the pants 10) (see FIG. 5).

  When more than two folds 213 are provided, the third and subsequent folds 213 extend in the lateral direction over the entire width of the covering cloth 203 in the same manner as the first and second folds 213A and 213B. ing.

  The third and subsequent folds 213C, 213D,... Are in the direction away from the upper edge of the covering cloth 203 on the path of the covering cloth 203 and below the preceding fold line (for example, the second fold line 213B). It is separated from the fold (for example, the second fold 213B) by a predetermined distance. In addition, the third and subsequent folds 213 are mountain-folded by odd-numbered folds 213 and valley-folded by even-numbered folds 213.

  For example, when only two folds 213 are provided, the upper edge of the cover cloth 203 formed in a bowl shape as described above is joined to the belt cloth 207 and the lower edge of the cover cloth 203 is the rear edge. By being bonded to the body 12, the covering cloth 203 extends from the upper end edge to the first fold line 213A from the upper edge to the first fold line 213A from the top to the bottom. In the portion of the covering cloth 203 between the first fold line 213A and the second fold line 213B, the covering cloth 203 extends from bottom to top from the first fold line 213A to the second fold line 213B. In the portion of the covering cloth 203 between the second fold line 213B and the lower end edge, the second fold line 213B extends from the top to the bottom from the lower end edge. So that the cover cloth 203 is stretched.

  Similarly, if there are more than two folds 213, for example, the even number (nth) fold 213, the even number fold 213, and the next odd number (n +) At the portion of the covering cloth 203 between the first and second folds 213, the covering cloth 203 extends from top to bottom from the even-numbered (n-th) fold 213 to the odd-numbered (n + 1) -th fold 213. In the portion of the covering cloth 203 between the odd-numbered (n + 1) fold 213 and the even-numbered (n + 2) fold 213 next to the odd-numbered fold 213, the odd-numbered The covering cloth 203 extends from the bottom to the top from the (n + 1) fold 213 to the even (n + 2) fold 213.

  At each fold 213, the lateral dimension of the covering cloth 203 that is folded 180 ° into a bowl-like rectangular shape is the width dimension of the stretchable fabric 201 (external force such as a tensile force is applied to the stretchable fabric 201. It is substantially equal to the width dimension in a state in which the stretchable fabric 201 is not stretched.

  In addition, the vertical dimension of the covering cloth 203 which is folded 180 degrees and is rectangular and rectangular at each fold 213 is the vertical dimension of the stretchable cloth 201 (such as the tensile force applied to the stretchable cloth 201). Of the vertical direction in the state where no external force is applied and the stretchable fabric 201 is not stretched).

  Then, the elastic fabric 201 is positioned at the inner side of the covering fabric 203 (the waist side of the wearer of the trousers 10), and the elastic fabric 201 is folded by 180 ° at each fold 213 and rectangular folds. The entire covering cloth 203 is overlapped with each other. Therefore, the stretchable fabric 201 does not appear outside the trousers 10.

  Here, the entire stretchable fabric 201 and the entire covering cloth 203 that is folded 180 ° at each fold 213 into a rectangular shape are overlapped with each other, and the upper end edge of the stretchable fabric 201 and the covering cloth are overlapped with each other. The state in which the upper end edge of 203 is sewn together and the lower end edge of the stretchable fabric 201 and the lower end edge of the covering cloth 203 are sewn together is referred to as a stretchable cloth covering cloth semi-joint state.

  In the semi-bonded state of the stretchable fabric covering cloth, the pulling force that stretches the stretchable fabric 201 and the covering cloth 203 in the vertical direction is set to the upper edge of the stretchable fabric 201 and the covering cloth 203, the stretchable fabric 201 and the covering cloth. When added to the lower end edge of 203, the stretchable fabric 201 and the covering fabric 203 extend in the vertical direction (although the stretchable fabric 201 is elastically deformed and the covering fabric 203 is extended by the fold formed by the fold 213). When the covering cloth 203 is fully extended and the fold 213 of the covering cloth 203 disappears, the covering cloth 203 is obstructed so that the stretchable cloth 201 and the covering cloth 203 do not extend any more. It is assumed that the stretchable fabric 201 is not fully stretched even when the covering fabric 203 is fully stretched.

  In addition, the covering cloth 203 is folded at each fold 213 (in a folded-up state), and has one end edge in the lateral direction of the covering cloth 203 (the left side extending in the vertical direction). The side or the vicinity thereof is integrally joined to the back body 12 together with the stretchable fabric 201 (sewn by a seam 217 extending in the vertical direction). Similarly, the other end edge in the horizontal direction of the covering cloth 203 (the right side extending in the vertical direction or a portion in the vicinity thereof) is integrally joined to the back body 12 together with the stretchable fabric 201. (Sewn by a seam 219 extending in the vertical direction).

  In addition, when the wearer of the trousers 10 is in an upright posture, the stretchable fabric 201 hardly extends. Further, the back body 12 is cut out in a rectangular shape at a part of the back body 12 where the stretchable fabric 201 and the covering cloth 203 are installed (see FIG. 4).

  Furthermore, the stretchable fabric 201 and the covering cloth 203 are formed larger than the sacrum of the wearer of the pants 10. More specifically, the width dimension of the stretchable fabric 201 and the covering cloth 203 is about 1.5 to 3.0 times (more preferably 1.5 to 2.0 times) the width of the sacrum. Thus, the vertical dimension of the stretchable fabric 201 and the covering cloth 203 is about 1.0 to 1.5 times the vertical dimension of the sacrum.

  When the wearer wearing the trousers 10 is viewed from behind, the stretchable fabric 201 and the covering cloth 203 cover the sacrum of the wearer of the trousers 10 and the peripheral portion (a part of the buttock).

  Further, for example, four (may be five or more) folds 213 (213A, 213B, 213C, 213D) are formed on the covering cloth 203 of the trousers 10. Among the folds 213, the covering cloth 203 is integrally joined to the stretchable cloth 201 at the even-numbered fold lines 213B and 213D from the top or in the vicinity of the even-numbered fold lines 213B and 213D (of the covering cloth 203). It is joined by a seam 221 extending over the entire length in the lateral direction). Thereby, the covering cloth and the stretchable cloth joining portion 225 are formed.

  And according to the wearer's skin elongation (skin elongation in the vertical direction) when the wearer of the trousers 10 is in a squatting position, each covering cloth / elastic cloth joining portion 225 and belt cloth The upper end edge portion of the stretchable fabric 201 and the covering cloth 203 joined to the 207 and the lower end edge portion of the stretchable fabric 201 and the covering cloth 203 joined to the back body 12 are adjacent to each other. The distance between the different parts is different from each other in the vertical direction. For example, the values of the dimension LA and the dimension LB shown in FIG. 5 are different from each other, and the dimension LB is larger than the dimension LA.

  More specifically, the cover cloth 203 is formed with four folds 213 (213A, 213B, 213C, 213D), and these folds 213 are formed from the upper side to the lower side. The first fold line (first fold line) 213A, the second fold line (second fold line) 213B, the third fold line (third fold line) 213C, and the fourth fold line (fourth fold line) 213D are arranged in this order. (See FIG. 5).

  As described above, the portion of the covering cloth 203 between the upper edge of the covering cloth 203 and the first fold 213A (the portion between the upper edge and the first fold) is from top to bottom from the upper edge to the first fold 213A. The covering cloth 203 is stretched toward the front.

  As described above, the portion of the covering cloth 203 between the first fold 213A and the second fold 213B (the portion between the first fold and the second fold) of the covering cloth 203 is the second fold from the first fold 213A. The covering cloth 203 extends from the bottom to the top along the fold line 213B. In the first crease / second crease part, the covering cloth 203 is shorter between the stretchable fabric 201 and the upper end edge / first crease part than the upper end edge / first crease part. Stretched (stretched short in the vertical direction).

  As described above, the portion of the covering cloth 203 (the portion between the second fold line and the third fold line) between the second fold line 213B and the third fold line 213C of the covering cloth 203 has the third fold line 213B to the third fold line. The covering cloth 203 extends from the top to the bottom over the fold line 213C. Moreover, the covering cloth 203 extends longer than the first crease / second fold portion at the second fold / third fold portion (extends longer in the vertical direction).

  In the portion of the covering cloth 203 (the third fold / fourth fold portion) between the third fold line 213C and the fourth fold line 213D of the covering cloth 203, it goes down from the third fold line 213C to the fourth fold line 213D. The covering cloth 203 extends upward from the top. Further, in the portion between the third fold and the fourth fold, the covering cloth 203 is disposed between the stretchable fabric 201 and the portion between the second fold and the third fold from the portion between the second fold and the third fold. Is also stretched short (shortly stretched in the vertical direction).

  In addition, at the portion of the covering cloth 203 (fourth fold / lower edge portion portion) between the fourth fold 213D of the covering cloth 203 and the lower end edge of the covering cloth 203, the fourth fold 213D extends from the top to the lower end edge. The covering cloth 203 extends downward. Further, the covering cloth 203 extends longer than the third fold / fourth fold portion at the fourth fold / lower end edge portion (extends longer in the vertical direction).

By the way, as shown in FIG. 5, in the vicinity of the second fold 213B of the covering cloth 203 (in the vicinity of the second fold 213B between the second fold 213B and the third fold 213C), The covering cloth 203 is stitched to the stretchable fabric by the seam 221 extending in the lateral direction over the entire width (the second covering cloth / stretchable fabric joining portion 225B is formed).
Further, in the vicinity of the fourth fold 213D of the covering cloth 203 (in the vicinity of the fourth fold 213D between the fourth fold 213D and the lower end edge), the seam 223 extending in the lateral direction over the entire width of the covering cloth 203 is used. The covering cloth 203 is stitched to the stretchable cloth 201 (the fourth covering cloth / stretchable cloth joining portion 225D is formed).

  Note that the second covering cloth / stretchable fabric bonding portion 225B is located above the fourth covering cloth / stretchable cloth bonding portion 225D.

  In the stretchable fabric 201, the distance between the upper edge of the stretchable fabric 201 (joint portion to the belt cloth 207) and the second covering cloth / stretchable fabric joint portion 225B (distance in the vertical direction). LA is smaller than a distance LB (distance in the vertical direction) LB between the second covering cloth / stretchable fabric joining portion 225B and the fourth covering cloth / stretchable fabric joining portion 225D.

  Thereby, when the wearer of the pants 10 takes a posture such as squatting and the skin of the waist and the buttock is stretched, the stretchable fabric 201 is appropriately stretched according to the elongation of the skin, and the wearer of the pants 10 feels uncomfortable ( The occurrence of pressure in the abdomen, etc.) can be avoided. That is, if the stretchable fabric 201 is not provided, as shown in FIG. 22B, when the wearer squats down, the belt part (belt) of the trousers falls downward, and the belt on the front side is worn by the wearer. The abdomen is compressed. Furthermore, the wearer's spine is also pressed by the abdominal pressure, which may cause back pain. However, in the trousers 10, as shown in FIG. 22A, the stretchable fabric 201 is stretched, so that the abdomen is not compressed and back pain does not occur.

  To explain further, when the wearer of the trousers 10 is in a squatting position, the amount of skin stretching increases from the waist to the buttocks (from the top to the bottom) from the waist to the buttocks (above the buttocks). The lower part of the groin area (the groin area) has higher skin elongation). Therefore, as described above, the upper side (between the upper end edge of the stretchable fabric 201 and the second covering cloth / stretchable fabric joining portion 225B) and the lower side (second covering cloth / stretchable fabric joining portion 225B). And the fourth covering cloth / stretchable cloth joining portion 225D), the stretchable cloth 201 is greatly stretched so that the waist part generated when the wearer of the trousers 10 is crouched or the like The discomfort in the buttocks and the pressure in the abdomen can be reduced, and the occurrence of back pain can be eliminated.

  In addition, between the fourth covering cloth / stretchable cloth joining portion 225D and the lower end edge (joining portion with the back body 12) of the covering cloth 203 (the portion of LC shown in FIG. 5), a flat plate shape is formed in the vertical direction. Since the covering cloth 203 and the flat stretchable cloth 201 overlap each other, even when the wearer of the trousers 10 is squatting, the stretchable cloth is obstructed by the covering cloth 203. 201 does not stretch. Therefore, the stretchable fabric 201 may be deleted from the LC portion shown in FIG.

  Further, as shown in FIG. 5, a seam (a seam extending over the entire length of the covering cloth) 227 is provided in the vicinity of the first fold 213A and the vicinity of the third fold 213C of the covering cloth 203. The covering cloths 203 overlap each other. Thereby, the shape of the folds 213A and 213D is maintained.

  Moreover, in the trousers 10, the collar part 13 is provided in the site | part corresponding to a wearer's crotch. This will be described in detail below with reference to the drawings.

  6 is a front view of the trouser 10 of the embodiment, and FIG. 7 is a rear view of the trouser 10. 6 and 7 are diagrams mainly for explaining the “U” -shaped collar portion 13, and therefore, the display of the waist stretchable portion (active ridge) 225 is omitted in FIGS. 6 and 7. ing. Similarly, in FIGS. 8 to 18, the display of the waist stretchable portion (active ridge) 225 is omitted.

  FIG. 8 is a side view of the upper half of the trouser 10 as viewed from the left side, FIG. 9 is a main part configuration diagram showing a state in which the left foot portion of the trouser 10 is folded over the right foot portion at the crotch position, and FIG. FIG. 11 is a cross-sectional view taken along line XX of FIG. 8 when wearing 10, FIG. 11 is a front body (a front body composed of a cloth having almost no stretchability such as a fabric) 11 and a rear body. FIG. 12 is a plan view showing a configuration of a heel and a heel part (a heel part made of a cloth having almost no elasticity such as a cloth), and FIG. 12 is a right foot part in a general case in which trousers are formed only by a front body and a back body FIG. 13 to FIG. 18 are diagrams showing a procedure for producing a collar pattern based on the pattern of FIG. 12, FIG. 13 is a diagram showing the first step, and FIG. 14 is a diagram of FIG. FIG. 15 is a diagram showing the next step of FIG. 14, and FIG. 16 is a diagram showing the next step of FIG. FIG. 17 is a diagram showing the next step of FIG. 16, and FIG. 18 is a plan view showing the configuration of the pattern of the right foot part of the pants of this embodiment obtained in the steps of FIGS. .

  As shown in FIGS. 6 and 7, the trouser 10 is obtained by sewing a pair of left and right front bodies 11, a pair of left and right rear bodies 12, and a heel part 13 on the inner crotch side. The heel part 13 is provided continuously from the skirt of the right foot portion 10R to the skirt of the left foot portion 10L.

  As shown in FIG. 8, the position of the crotch inner side edge 11a of the front body 11 and the crotch inner side edge 12a of the back body 12 is the boundary line P between the region that stretches greatly when the legs are opened and the region that does not stretch easily (FIG. 13). The position is set to be shifted to the front and rear sides. The line indicated by Q in the figure is the position of the seam between the crotch inner side edge of the front body and the crotch inner side edge of the back body in the conventional case where the heel part 13 is not added. In FIG. 8, the left side is the front side F, and the right side is the rear side R.

  The heel part 13 is interposed in a space between the crotch inner side edge 11a of the front body 11 and the crotch inner side edge 12a of the rear body 12 which are shifted to the front side and the rear side. The length direction dimension L2 of the upper thigh at the center in the direction is larger than the length direction dimension L1 of the upper thigh at the position (Q position) of the crotch inner side edge of the front body and the crotch inner side edge before shifting the position. It is set long. Thereby, as shown in FIG. 9, the length L3 of the crotch center part of the collar part 13 of the leg opening direction is longer than the conventional one.

  Then, as shown in FIG. 11, the collar part 13 made of the cut three parts 13 </ b> A, 13 </ b> B, and 13 </ b> C is stitched together to produce an integral collar part 13. The trouser 10 of embodiment is produced by sewing the body 12 together. That is, the front side edge 13a of each of the left and right buttocks 13 and the crotch inner side edge 11a of the front body 11 are stitched together at the seam 22, and the rear side edge 13b of the buttocks 13 and the crotch inner side edge of the back body 12 are also sewn. 12a are sewn together at the seam 23, the crotch outer side edge 11b of the left and right front bodies 11 and the crotch outer side edge 12b of the rear body 12 are sewn together by a seam not shown, and the torso portions of the left and right front body 11 are joined together. The trousers 10 of the embodiment are manufactured by sewing together via a chuck member (not shown) and sewing the body parts of the left and right rear body 12 with the seam 21 to grip the body part.

  In this stitched state, the positions of the crotch inner side edges 11a, 12a of the front body 11 and the back body 12 and the seams 22, 23 of the heel part 13 are inconspicuous positions on the crotch side when viewed from the front and rear. is there. The positions of the crotch inner side edges 11a and 12a of the front body 11 and the back body 12 and the seams 22 and 23 of the heel part 13 are positions where the expansion and contraction of the skin on the inner crotch side is large and small when the legs are closed and opened. Is set at the boundary. That is, in this embodiment, it is a position where both conditions match.

  In addition, the heel part 13 is integrally formed at the crotch part at both legs without a seam. Here, the crotch part 131 is formed of an integral continuous cloth, and the thigh lower part 132 connected thereto is a seam 24. It is composed of another cloth.

  Next, a manufacturing method for obtaining the trousers (trousers excluding the belt part 205 and the waist elastic part 215) 10 will be described.

  Finally, the cloth is cut into a shape as shown in FIG. 11 and sewed. First, a procedure for making a pattern will be described with reference to FIGS. Here, only the pattern on the right foot side is illustrated and described. Further, description will be made with the same reference numerals for the pattern paper and the cloth.

  First, a pattern in a conventional case in which trousers are formed only by the front body and the back body is prepared. FIG. 12 shows a conventional pattern, 11 is a front body, 11a is a crotch inner side edge, 11b is a crotch outer side edge, 12 is a back body, 12a is a crotch inner side edge, and 12b is a crotch outer side edge. .

  At this pattern paper stage, as shown in FIG. 13, a boundary line P between a region S2 that greatly expands and contracts when the front body 11 and the back body 12 are opened and a region S1 that hardly stretches is determined.

  Next, as shown in FIG. 14, the pattern paper is cut (cut) at the boundary line P, and each position of the crotch inner side edge 11 a of the pattern of the front body 11 and the crotch inner side edge 12 a of the pattern of the rear body 12 is detected. Is newly set at the cut position. That is, by cutting the pattern paper at the position of the boundary line P between the region S2 that greatly expands and contracts when the legs are opened and the region S1 that is difficult to expand and contract, the crotch inner side edge 11a of the front body 11 and the back The position of the crotch inner side edge 12a of the body 12 is shifted to the front side and the rear side, respectively.

  Next, as shown in FIG. 15, the front and rear side edges of the first piece 111 separated from the pattern of the front body 11 and the second piece 112 separated from the pattern of the back body 12 by the cutting are curved upper knees. The portion is divided into a plurality of small pieces 111a and 112a in the vertical direction.

  Then, as shown in FIG. 16, the plurality of small pieces 111 a on the first piece 111 side are maintained in the height direction dimension of the front side edge 111 c of the first piece 111, and the rear side edge 111 d of each small piece 111 is the first piece 111 a. The shape of the first piece 111 is corrected by rearranging it so as to be aligned on the line R1 directly above the skirt E of the one piece 111. That is, the shape of the first piece 111 is corrected by rearranging the small pieces 111a so that the rear side edge 111d is aligned on the straight line R1 with the K1 point in the drawing of each small piece 111a as a base point.

  Similarly, the plurality of small pieces 112 a on the second piece 112 side are maintained in the height direction dimension of the rear side edge 112 c of the second piece 112, and the front side edge 112 d of each small piece 111 is the second piece 112. The shape of the second piece 112 is corrected by rearranging it so as to line up on the line R2 directly above the skirt E. That is, the shape of the second piece 112 is corrected by rearranging the small pieces 112a so that the front side edge 112d is aligned on the straight line R2 with the K2 point in the drawing of each small piece 112a as a base point.

  Next, as shown in FIGS. 17 and 18, the first side 111 of the first piece 111 located on the straight lines R1 and R2 after correction is combined with the front side edge 112d of the second piece 112 to match the first side. After the piece 111 and the second piece 112 are combined, the size correction 102 to 103 of the stitched portion between the front body 11 and the back body 12 is added to the upper portion, so that the crotch inner side of the pattern of the front body 11 at a shifted position A pattern of the collar 13 that fits in the space between the side edge 11a and the crotch inner side edge 12a of the pattern of the back body 12 is formed.

  Then, the front body 11, the back body 12, and the heel part 13 are cut from the material cloth according to the patterns, and the crotch inner side edge 11a of the left and right front parts 11 and the front side edge 13a of the heel part 13 are sewn together. After sewing the crotch inner side edge 12a of the body 12 and the rear side edge 13b of the collar part 13, and further sewing the crotch outer side edge 11b of the front body 11 and the crotch outer side edge 12b of the back body 12, The trousers 10 are produced by sewing the front body 11 and the back body 12 together and gripping the torso.

  According to the trousers 10 thus produced, the heel part 13 is formed in the space between the crotch inner side edge 11a of the front body 11 and the crotch inner side edge 12a of the rear body 12 which are set to be shifted in the front side and the rear side, respectively. The length direction dimension L2 of the center part in the front-rear direction of the heel part 13 is set longer than the length direction dimension L1 of the crotch inner side edge of the front body before shifting the position and the crotch inner side edge of the rear body. Therefore, it is possible to exert a good open leg mobility while maintaining a smart appearance. That is, as shown in FIG. 10, a margin can be given to the inner crotch portion, and the open leg mobility can be improved. In FIG. 10, the dimensions of the flange 13 are exaggerated for clarity.

  Moreover, since the position of the seam of each crotch inner side edge 11a, 12a and the collar part 13 of the front body 11 and the back body 12 is set to the position hidden when it sees from the front and back, it looks Can be better. Further, the positions of the crotch inner side edges 11a and 12a of the front body 11 and the back body 12 and the seams 22 and 23 of the buttocks 13 are positions where there is no expansion and contraction of the skin on the inner crotch side when the legs are closed and when the legs are opened. Therefore, when the legs are closed, there is no feeling of tension by the buttocks 13, so that the open leg mobility can be improved reliably. Further, the range of the heel portion 13 can be kept in the inner crotch region as much as possible, and the seams 22 and 23 can be made inconspicuous. Further, in this trouser 10, the seam 24 for joining the heel part 13 is not located in the crotch part, so that the stiff feeling (stiffness) due to the seam 24 can be eliminated.

  Moreover, in trousers 10, as shown in FIG. 4 etc., a part of longitudinal direction (direction of a wearer's waist) of the cyclic | annular belt part 205 is comprised so that expansion-contraction is possible.

  For example, in the belt portion 205, portions corresponding to the left and right side portions of the waist of the wearer of the trousers 10 are elastic and elastic. The part of the belt portion 205 that can be stretched is configured by covering an elastic body such as a rubber string with a cylindrical belt cloth 207.

  More specifically, the rear end portion 229A1 of the left belt portion expansion / contraction portion 229A in the portion (a pair of belt portion expansion / contraction portions) 229 (229A, 229B) of the belt portion 205 configured to be extendable / contracted is formed of trousers. 10 in the lateral direction, it is located at substantially the same position as the left end of the waist elastic part 215 (see FIG. 4). Further, the front end portion 229A2 of the left belt portion expansion / contraction portion 229A is located at the left groin portion (left end of the groin portion) of the wearer of the trousers 10.

  Similarly, the rear end portion 229B1 of the right belt portion stretchable portion 229B is located at substantially the same position as the right end of the waist stretchable portion 215 in the lateral direction of the trouser 10 (see FIG. 4). Further, the front end portion 229B2 of the right belt portion expansion / contraction portion 229B is located at the right groin portion of the pants 10 wearer (the right end of the groin portion).

  According to the trousers 10, the stretchable fabric 201 and the covering cloth 203 covering the stretchable fabric 201 are provided only at the waist of the wearer. 203 is not so conspicuous (the change part is inconspicuous), and the stretchable fabric 201 expands and contracts appropriately as the wearer exercises, so that the wearer can easily move, and the stretchable fabric 201 No pilling or snacking occurs, so it can withstand long wear.

  Furthermore, according to the trouser 10, since the site | part corresponding to a wearer's waist | hip | lumbar part is the elastic fabric 201, and also the elastic fabric 201 is covered with the covering cloth 203, the wearer of pants 10 (operator ) When the operator bends his / her waist such as crouching or standing knee, the appearance is prevented from deteriorating, the abdominal pressure of the worker is reduced, and back pain can be further reduced. .

  That is, since the stretchable cloth 201 is covered with the heel-shaped covering cloth 203, even when the wearer of the trousers 10 bends (bends forward) the waist, the covering cloth 203 is appropriately expanded and contracted to expose the stretchable cloth 201. There is nothing to do so the appearance will not deteriorate.

  Further, even if the wearer (operator) of the trouser 10 bends the waist and the skin of the operator's waist extends in the vertical direction, the stretchable fabric 201 extends in accordance with the elongation of the skin. In the rear portion of the belt portion 205, a gap is hardly formed between the rear portion of the belt portion 205 of the trouser 10 and the waist portion of the operator. The pressure on the worker's abdomen is reduced, and back pain can be reduced by reducing the pressure on the abdomen.

  Furthermore, even if the wearer (operator) of the trousers 10 bends the waist, the skin of the operator's waist and the like extends in the vertical direction, and the stretchable fabric 201 extends according to the elongation of the skin. Since the covering cloth 203 also extends in the same manner, the stretchable cloth 201 is not exposed, and the stretch of the stretchable cloth 201 and the covering cloth 203 causes the rear portion of the belt portion 205 of the trouser 10 and the operator's waist. Since almost no gap is formed between them, the appearance is prevented from deteriorating.

  More specifically, in the conventional trousers, unlike the jumpsuit, the upper garment is separated and only the lower garment is formed, so that the wearer of the trousers bends the waist (forward bending) as shown in FIG. If it does, the belt part of trousers will fall below and the part of a wearer's waist will be exposed, for example, the gap mentioned above is formed. In some cases, the shirt (hem) placed in the pants goes out of the pants and becomes unsightly. By exposing the lower back part, the body cools down, causing adverse effects such as making it easier to catch a cold.

  On the other hand, in the trouser 10, as shown in FIG. 22 (a), even if the pants wearer flexes (bends forward) the waist, the stretchable fabric 201 stretches according to the elongation of the skin. It is not exposed and the waist is kept warm.

  In addition, even if the wearer of the trousers 10 is squatting, it is avoided that the shirts such as upper garments protrude from the hem of the trousers 10 (the belt portion), the underwear is not exposed, and the appearance is deteriorated. It is avoided that the shirt protruding from the trousers 10 is caught on the protrusion, and the occurrence of a situation where the shirt is caught in the machine is avoided.

  Further, even if the wearer of the trousers 10 is squatting, it is avoided that sparks such as filth, debris and welding work enter the trousers 10 from the hem of the trousers 10, and the wearer is prevented from being injured.

  Moreover, since there is almost no loss of wear, there is almost no need to correct the loss of wear and it is possible to cope with emergencies.

  Furthermore, since the elastic fabric 201 is provided, even if the trousers 10 stick to the wearer's skin with sweat, the operation of squatting does not become difficult.

  Further, according to the trousers 10, the apparently changed portion (changed portion with respect to the conventional trousers) that can be recognized by a person with normal attention is at the covering cloth 203. However, it can be said that it satisfies elegance, fashionability, contribution to corporate PR, friendliness, and group beauty.

  Also, according to the trousers 10, unlike the jumpsuits, the upper garment part naturally does not exist, so that it is difficult for the wearer of the trousers 10 to write characters or to operate the keyboard and mouse of the personal computer. In addition, a stiff shoulder (a stiff shoulder due to the pants 10) does not occur in the wearer of the pants 10.

  Further, in the sitting position, even if the trouser 10 is sandwiched between the wearer and the chair at the buttocks of the wearer of the trousers 10, there is no upper garment part, so the waist is swung (through the center of the person to the horizontal plane) Therefore, it is difficult to move the body, for example, it is difficult to perform an operation such as turning around an orthogonal axis.

  Moreover, according to the trousers 10, since the upper garment is separated and is composed only of the lower garment, the opening is larger (particularly larger at the waist) than the jumpsuit, and the air permeability is good. , Can reduce the summer heat feeling. On the other hand, in winter, as described above, the waist is kept warm.

  Moreover, according to the trousers 10, since the plurality of folds 213 are formed in the covering cloth 203 and the covering cloth 203 has a plurality of ridges, the covering cloth 203 has a one-stage ridge. Compared to the above, the amount of stretch of the covering cloth 203 can be increased, and the pressure on the abdomen of the wearer of the trouser 10 can be further reduced when the wearer of the trouser 10 takes a squatting posture or the like. .

  That is, at the waist of the wearer corresponding to the stretchable fabric 201 (covering cloth 203) of the trouser 10, the skin is 130% to 150% when the wearer is squatting compared to when the wearer is standing upright. Although it stretches, the covering cloth 203 is formed in a plurality of ridges so that it can easily cope with the above-described skin stretch.

  Further, according to the trousers 10, since the “U” -shaped heel part 13 and the waist elastic part 215 are provided, the combination of the “U” -shaped heel part 13 and the waist elastic part 215, When the wearer of trousers 10 squats down without crushing the 10 tubular parts (the part where the leg of the wearer of trousers 10 enters), the trousers 10 are pulled by the crotch and thighs of the wearer of trousers 10 I don't feel

  That is, when the wearer wears a normal form of trousers that are not provided with the “U” -shaped buttocks 13 or the waist elastic part 215, the wearer Slightly tuck the cylindrical part of If you don't squeeze it, when you actually squat down, a large pulling force will be applied to the trousers at the part corresponding to the waist and knees of the trousers, giving the wearer a feeling that the trousers are likely to break .

  However, in the trousers 10 provided with the “U” -shaped buttocks 13 and the waist elastic part 215, the “U” -shaped buttocks 13 and the waist can be used even if the wearer of the trousers 10 squats down. By providing the expansion / contraction part 215, the part corresponding to the waist part or the knee part of the trouser 10 does not give the wearer a feeling of being stretched or the trouser 10 is likely to be broken.

  In addition, according to the trousers 10, a part of the belt portion 205 in the longitudinal direction (the direction around the waist of the wearer) is configured to be stretchable, so that when the wearer of the trousers 10 is bent, the waist is bent. However, coupled with the provision of the waist stretchable part 215, the pressure applied to the abdomen of the wearer of the pants 10 can be further reduced.

  Moreover, according to the trousers 10, the sacral portion of the wearer and the peripheral part thereof are thicker than the other body parts (overlapping cloths) with the heel-shaped covering cloth 203 and the stretchable cloth 201. An annular portion between the belt line and a portion slightly lowered from the belt line by, for example, about 10 cm to 20 cm (about the same as or slightly longer than the height of the waist elastic portion 215). In the cylindrical part), the part of the pants 10 is in close contact with the wearer's skin directly or through the underwear.

  This prevents the waist of the wearer of trousers 10 from getting cold (the waist is kept warm). When walking outside the house wearing trousers 10 in winter, the waist is warm and warm, and even a healthy person who has no disability such as back pain is extremely comfortable. In particular, since the elastic fabric 201 has a fine net shape, the air accumulated in the fine mesh portion of the elastic fabric 201 functions as a heat insulating material, and the waist is further kept warm. It is.

  On the other hand, in the jumpsuit of patent document 1 and patent document 2, even if the place of the waist part of the jumpsuit is covered with a thick cloth (overlapping cloth), there is a space between the jumpsuit and the waist part of the wearer. Therefore, it cannot be expected that the waist of the wearer such as the pants 10 is kept warm.

  Here, the measurement result etc. of the clothing pressure in a wearer's abdomen and waist | hip | lumbar part when putting on the trousers 10 are shown.

  The measurement of the clothing pressure is performed so that the wearer puts on the trousers 10 (pants) or the conventional trousers (pants), installs a belt through the belt through 206 on the outer periphery of the belt portion 205, and the trouser 10 does not fall by the belt. A pressure sensor was installed between the belt portion 205 and the belt with the waist appropriately tightened.

  As shown in FIG. 19, the position of the pressure sensor is as follows: left lower scapula P1, lower left flank P2, lower left nipple P3, midline P4, right lower nipple P5, right lower heel P6, right Seven locations of P7 immediately below the scapula were used.

  The wearer takes the upright posture (standing posture) shown in FIG. 21 (a), the standing knee posture shown in FIG. 21 (b), and the chair sitting posture shown in FIG. 21 (c). The pressure between the unit 205 was measured. In addition, the measurement of the pressure in the upright posture in the pants 10 is omitted.

  The wearers are A and B. The former is a man with a physique of 172cm tall, 78kg weight, and 88cm waist. B is a physique male with a height of 169 cm, a weight of 72.5 kg, and a waist of 90 cm.

  FIG. 20 shows the measurement result of pressure by the pressure sensor. In addition, the value (a unit is kPa) shown in FIG. 20 is an average value. This average value is an average value for a measurement time of 10 seconds, and more specifically, an average value of pressures measured 11 times every second for 10 seconds.

  FIG. 20A shows pressure measurement results (seven measurement results) when a conventional ordinary pant is worn on the upper and an upright posture, a standing knee posture, and a chair-sitting posture are taken.

  FIG. 20B shows pressure measurement results (seven measurement results) when the trouser 10 is worn on the back and the kneeling posture and chair-sitting posture are taken.

  FIG. 20C shows pressure measurement results (seven measurement results) when the conventional ordinary pants are worn by the heel and take an upright posture, a standing knee posture, and a chair-sitting posture.

  FIG. 20 (d) shows the pressure measurement results (seven measurement results) when the trousers 10 are put on the trousers 10 and the standing knee posture and the chair sitting posture are taken.

  As apparent from FIG. 20, the pressure (clothing pressure) detected by the pressure sensor is larger when the standing knee posture and the chair sitting posture are taken than when the posture is upright. In addition, although there are individual differences between the former and the second, when comparing the clothing pressure of the normal pants and the clothing pressure of the trousers 10, the clothing pressure on the wearer's front surface (abdominal side) is particularly large when taking a standing knee posture. The pants 10 are reduced. In addition, even when taking a chair-sitting posture, the clothes pressure applied to the wearer's front surface (abdominal side) is reduced by the trousers 10 although not as much as the standing knee posture.

  Furthermore, the clothing pressure is generally set to 3.92 kPa, but the maximum value for the trousers 10 is 2.83 kPa, and all the clothing pressures are below the allowable value.

  Thereby, in the trousers 10, in addition to the above-described effects such as prevention of the occurrence of low back pain, the wearer suppresses physiological phenomena such as an increase in blood pressure, an increase in pulse, sweating, fatigue, headache, and vomiting. Can do.
