Description

[Technical field]

[0001] The present invention relates to work clothing. [Background technology]

[0002] Patent Document 1 discloses a work suit (coveralls) that is an integrated top and bottom garment. A zipper is sewn to the left shoulder of this work suit, making it possible to open the left shoulder from the collar to the sleeve, and making it relatively easy to put on and take off the work suit (putting on and taking off the work suit). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Utility model registration No. 3165666 Summary of the Invention [Problem to be solved by the invention]

[0004] In this type of workwear, when putting the arms through the sleeves, the wearer must bend the elbow, insert the hand into the armhole, and pull up the entire workwear from below by rotating the arm from back to front. However, in order to insert the hand into the armhole, it is necessary to secure a space between the armhole and the wearer's torso. However, since the workwear is sewn with a relatively strong material, it is still difficult to put on even if the left shoulder part is made openable by a zipper. Therefore, the workwear of Patent Document 1 still has room for improvement in terms of putting on and taking off.

[0005] To provide work clothes that are easy to put on and take off by easily inserting and removing arms into and from the sleeves. [Means for solving the problem]

[0006] The present invention provides work clothes comprising a back portion having a front left portion and a front right portion divided by an openable front opening extending downward from the upper end of the front side, and a back portion connected to these, a pair of left and right sleeve portions connected to armholes on both sides of the upper part of the back portion, a collar portion connected to the upper end of the back portion and extending circumferentially from the front opening side of the front left portion, through the back portion to the front opening side of the front right portion, and a stretchable portion for allowing circumferential stretching of the collar portion, wherein the stretchable portion has a first portion constituting at least a part of the collar, and a second portion connected to the first portion, extending downward, and constituting part of the back portion.

[0007] The work clothes have a first portion constituting at least a part of the collar, and a second portion constituting a part of the back, and are provided with an elastic portion for allowing the collar to stretch in the circumferential direction. As a result, when putting on or taking off the work clothes, at least a part of the collar and a part of the back can be stretched by the elastic portion. Therefore, when putting on the work clothes, the armholes can be moved away from the wearer's torso, making it easy to insert the hands into the armholes and pull up the entire work clothes from below. This makes it easy to put on the work clothes. In addition, when taking off the work clothes, the elbows can be easily removed from the armholes. This makes it easy to take off the work clothes. Effect of the Invention

[0008] In the present invention, the arms can be easily inserted and removed from the sleeves, making putting on and taking off the garment easy. [Brief description of the drawings]

[0010] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0011] (First embodiment) 1 and 2, coveralls 10, which is an example of work clothing according to a first embodiment of the present invention, are integrally comprised of an upper garment 12 and a lower garment 20. This coveralls 10 can be easily put on and taken off by forming a part of the upper garment 12 as a stretchable stretchable part 16.

[0012] The top 12 comprises a back section 13, a pair of left and right sleeve sections 14, and a collar section 15. The back section 13 is tubular and covers the upper torso above the waist of the wearer 1 shown in Figures 3 and 4. The pair of sleeve sections 14 are each tubular and connect to both sides of the upper part of the back section 13 to cover the arms of the wearer 1. The collar section 15 is C-shaped with an open front side when viewed from above, connects to the upper end of the back section 13, and covers the base of the neck of the wearer 1. The stretchable section 16 is sewn (joined) to the upper part of the back side of the back section 13, and constitutes part of the back section 13 and part of the collar section 15.

[0013] The bottom garment 20 comprises a crotch portion 21 and a pair of left and right leg portions 22. The crotch portion 21 is generally cylindrical, connected to the lower end of the back portion 13, and covers the lower part of the torso of the wearer 1 below the waist. The leg portions 22 are each cylindrical, connected to both sides of the lower end of the crotch portion 21, and cover the legs of the wearer 1. A pair of left and right pockets 23 are provided on both the front and back sides above the crotch portion 21, and a belt portion (waistband) 24 is provided above these. However, the pockets 23 and the belt portion 24 do not have to be provided.

[0014] A front opening 26 is provided at the center of the front side of the coveralls 10. This front opening 26 is provided across the top 12 and bottom 20 from the top of the back 13 to the vicinity of the crotch 21a, which is the bottom end of the crotch 21. The front opening 26 is formed by overlapping parts of a left front body (left side of the front) 30 and a right front body (right side of the front) 31, which will be described in detail later. A line fastener (not shown) is sewn to the left front body 30 and the right front body 31 to switch between an open state in which they are separated from each other and a closed state in which they are connected to each other. However, the front opening 26 may be configured to be openable and closable by a hook-and-loop fastener or a dot fastener.

[0015] 1 and 2, the back portion 13, the crotch portion 21, and the pair of left and right leg portions 22 are made up of a left front body portion 30, a right front body portion 31, an upper back body portion (rear body portion) 32, a left lower back body portion 33, and a right lower back body portion 34. The stretchable portion 16 is sewn to the upper center of the upper back body portion 32. Here, the left and right described in this specification correspond to the left and right of a wearer 1 wearing the coveralls 10.

[0016] The left front body 30 includes a left front torso covering part 30a covering the left half of the front torso of the wearer 1 from the shoulders down, and a left front leg covering part 30b covering the front side of the left leg of the wearer 1. The right front body 31 includes a right front torso covering part 31a covering the right half of the front torso of the wearer 1 from the shoulders down, and a right front leg covering part 31b covering the front side of the right leg of the wearer 1. The left front leg covering part 30b protrudes integrally from the lower end of the left front torso covering part 30a. The right front leg covering part 31b protrudes integrally from the lower end of the right front torso covering part 31a. However, the left front body 30 and the right front body 31 may be configured separately into an upper part constituting the back part 13 and a lower part constituting the crotch part 21 and the leg part 22.

[0017] The left front torso covering part 30a and the right front torso covering part 31a form the front part of the back part 13 and the crotch part 21. The left front torso covering part 30a and the right front torso covering part 31a are formed with width dimensions that overlap each other at the center in the body width direction, and this overlapping part forms the front opening part 26. Line fasteners (not shown) are sewn to the overlapping parts of the left front torso covering part 30a and the right front torso covering part 31a.

[0018] The upper back body 32, together with the sewn portion 16a of the stretchable portion 16, constitutes the back portion of the back portion 13 and covers the back (rear torso) of the wearer 1. With reference to Figures 1 to 3, the upper back body 32 is sewn to the left front body 30 and the right front body 31. This sewing forms two seams (joining lines) 36a, 36b between the upper back body 32 and the left front body 30, and two seams (joining lines) 36c, 36d between the upper back body 32 and the right front body 31.

[0019] The seam line (first seam line) 36a is formed between the upper left end of the upper back body 32 and the upper end of the left front body 30 to correspond to the top of the left shoulder of the wearer 1, and extends in the body width direction. The seam line 36b is formed between the left edge of the upper back body 32 and the side edge of the left front body 30 to correspond to the left underarm of the wearer 1, and extends in the vertical direction. The seam line (second seam line) 36c is formed between the upper right end of the upper back body 32 and the upper end of the right front body 31 to correspond to the top of the right shoulder of the wearer 1, and extends in the body width direction. The seam line 36d is formed between the right edge of the upper back body 32 and the side edge of the right front body 31 to correspond to the right underarm of the wearer 1, and extends in the vertical direction.

[0020] The back section 13 is formed by sewing the left front body 30 and the right front body 31 to the upper back body 32 including the stretchable section 16. Endless armholes 13a are formed on both sides of the upper part of the back section 13, and tubular sleeves 14 are sewn to these armholes 13a. A neckline 13b is formed at the upper end of the back section 13, and a collar section 15 (front collar section 15a) is sewn to this neckline 13b. The specific configuration of the collar section 15 will be described in detail later.

[0021] 1 and 2, the left lower back body 33 includes a left buttock covering part 33a that covers the left buttock of the wearer 1, and a left rear leg covering part 33b that covers the rear side of the left leg of the wearer 1. The right lower back body 34 includes a right buttock covering part 34a that covers the right buttock of the wearer 1, and a right rear leg covering part 34b that covers the rear side of the right leg of the wearer 1. The left rear leg covering part 33b protrudes integrally from the lower end of the left buttock covering part 33a. The right rear leg covering part 34b protrudes integrally from the lower end of the right buttock covering part 34a.

[0022] The left buttock covering portion 33a and the right buttock covering portion 34a are sewn to the lower end of the upper back body 32. The left buttock covering portion 33a and the right buttock covering portion 34a are sewn to each other at the rear crotch portion located in the center of the body width direction. Both side edges of the left back leg covering portion 33b including the side edges of the left buttock covering portion 33a are sewn to both side edges of the left front leg covering portion 30b including the side edges of the left front torso covering portion 30a of the left front body 30. Both side edges of the right back leg covering portion 34b including the side edges of the right buttock covering portion 34a are sewn to both side edges of the right front leg covering portion 31b including the side edges of the right front torso covering portion 31a of the right front body 31. This forms a crotch portion 21 connected to the lower end of the back portion 13 and a pair of tubular left and right legs 22 connected to the crotch portion 21.

[0023] Next, the back portion 13, the collar portion 15, and the stretchable portion 16 will be described in more detail.

[0024] 3 to 5, the upper back body 32 constituting a part of the back side of the back length portion 13 has a U-shaped cutout 32a cut out at the center in the body width direction at the upper end. A pair of upper ends 32b of the cutout 32a constitute the ends on the center side in the body width direction of the seams 36a, 36c sewn to the left front body 30 and the right front body 31. The lower end 32c of the cutout 32a is set to be located between the shoulder blades of the wearer 1.

[0025] The stretchable part 16 is sewn to the cutout 32a of the upper back body 32. More specifically, the stretchable part 16 is connected to the upper back body 32 by folding a roughly oval-shaped piece of fabric along its short axis and sewing it to the cutout 32a. A seam 37 is formed around the cutout 32a by the sewing.

[0026] The long axis dimension of the elliptical fabric constituting the stretchable portion 16 is greater than twice the depth D from the upper end 32b to the lower end 32c of the cutout 32a. As a result, the stretchable portion 16 is configured to include a sewn portion (second portion) 16a that is sewn to the upper back body 32 and forms part of the back side of the back length portion 13, and a protruding portion (first portion) 16b that protrudes from the upper end 32b of the cutout 32a and forms part of the collar portion 15. However, the stretchable portion 16 may be configured by sewing a roughly semi-elliptical fabric to the cutout 32a without folding it twice.

[0027] The sewn part 16a has the same shape as the cutout part 32a of the upper back body 32, and together with the upper back body 32 forms the back part of the back section 13. In other words, the sewn part 16a extends downward to a part corresponding to the shoulder blades of the wearer 1. The dimension of the sewn part 16a in the body width direction gradually decreases from the top to the bottom.

[0028] The height dimension of the sewn portion 16a is the same as the depth D of the cutout portion 32a. If the height dimension of the sewn portion 16a is made too small, the stretch length of the sewn portion 16a in the width direction and the stretch length of the protruding portion 16b in the circumferential direction cannot be ensured. Therefore, the height dimension of the sewn portion 16a (depth D of the cutout portion 32a) is preferably set to 5% to 100% of the back length H of the back length portion 13 from the neckline 13b (upper end portion 32b) to the upper end of the belt portion 24, and is set to 33% in this embodiment.

[0029] The dimension of the maximum width of the sewn part 16a corresponds to the width of the protruding part 16b, and is the same as the width W1 between the pair of upper ends 32b of the cutout part 32a, which is the width of the neckline 13b. If the dimension of the maximum width of the sewn part 16a is made too small, the stretch length of the sewn part 16a in the body width direction and the stretch length of the protruding part 16b in the circumferential direction cannot be ensured. Therefore, it is preferable that the dimension of the maximum width of the sewn part 16a is set to 10% to 100% of the shoulder width, i.e., the maximum width W2 of the pair of upper edges of the upper back body 32, and in this embodiment it is set to 40%.

[0030] The protruding portion 16b is integrally formed with the sewn portion 16a and has the same width as the maximum width thereof, and protrudes upward from the sewn portion 16a and the neckline 13b. The protruding portion 16b is not sewn to any of the upper back body 32, the left front body 30, and the right front body 31. A pair of side edges 16c located on both sides of the protruding portion 16b in the body width direction are adjacent to the inside of the seam lines 36a, 36c between the left front body 30 and the right front body 31 and the upper back body 32. The pair of side edges 16c are sewn to the pair of front collars 15a, respectively. When the dimension of the maximum width portion of the sewn portion 16a is set to be less than 40%, the pair of side edges 16c are located on the back side of the seam lines 36a, 36c.

[0031] The fabric (second fabric) constituting the stretchable portion 16 is made of a stretch material (elastic material) that is more elastic than the fabric (first fabric) constituting the left front body 30, right front body 31, upper back body 32, lower left back body 33, lower right back body 34, sleeve portion 14, and front collar portion 15a shown in Figures 1 and 2, i.e., the portions other than the stretchable portion 16. More specifically, it is preferable to use a stretch material with an elongation rate (JIS L 1096) of 7% or more for the stretchable portion 16, and in this embodiment, a stretch material with an elongation rate of 50%, i.e., a fabric that can be stretched to 150 cm from 100 cm in a contracted state, is used.

[0032] 1 and 2 are made of a material that is stronger and more durable than the fabric making up the stretchable section 16, and in this embodiment is made of a non-stretchable material that has a stretch rate of 0% and is not stretchable. However, the fabric making up the parts other than the stretchable section 16 may be stretchable as long as it is less stretchable than the stretchable section 16.

[0033] For example, the second fabric constituting the stretchable portion 16 may be a knit fabric. The first fabric constituting the portion other than the stretchable portion 16 may be a woven fabric (plain weave). The knit fabric constituting the second fabric has a blend ratio of 80% nylon and 20% polyurethane. The knit fabric has a count of 56 decitex nylon and 44 decitex polyurethane. The knit fabric has a basis weight of 225 g / m2 and a density (grey) of 178 inches. The woven fabric constituting the first fabric has a blend ratio of 65% polyester and 35% cotton. The woven fabric has a count of 45 in both the vertical and horizontal directions. The woven fabric has a basis weight of 180 g / m2 and a density (grey) of 102 threads vertically and 55 threads horizontally.

[0034] The collar portion 15 is composed of a pair of front collar portions 15a and a protruding portion 16b provided on the stretchable portion 16.

[0035] As described above, the pair of front collars 15a are made of a non-stretchable fabric and are stronger than the stretchable portion 16. The left-side of the pair of front collars 15a is sewn to the upper end (neckline 13b) of the left front body 30 and extends from the upper end of the front opening 26 to seam line 36a. The right-side of the pair of front collars 15a is sewn to the upper end of the right front body 31 and extends from the upper end of the front opening 26 to seam line 36c. As a result, a seam line 38 is formed around the neckline 13b.

[0036] As described above, the protruding portion 16b of the stretchable portion 16 protrudes above the neckline 13b by sewing the sewn portion 16a to the cutout portion 32a of the upper back body 32. The upper end of the protruding portion 16b and the upper ends of the pair of front collar portions 15a are at the same height.

[0037] The left side edge 16c of the protrusion 16b and the side edge 15b of the left front collar 15a are adjacent to the seam line 36a and sewn together. The right side edge 16c of the protrusion 16b and the side edge 15b of the right front collar 15a are adjacent to the seam line 36c and sewn together. By these stitching, a seam line 39 is formed between the protrusion 16b and the pair of front collars 15a. As a result, one collar 15 is formed that extends in the circumferential direction from the end of the left front body 30 on the front opening 26 side, through the seam 16a that constitutes the back part of the back part 13, to the end of the right front body 31 on the front opening 26 side.

[0038] If the proportion of the circumference P2 of protrusion 16b to the circumference P1 from one end to the other end of collar 15 is made too small, it is impossible to ensure the circumferential stretch length of protrusion 16b. Therefore, the proportion of the circumference P2 of protrusion 16b to the circumference P1 of collar 15 is preferably set to 5% or more and 100% or less, and in this embodiment it is set to 50%.

[0039] In the coveralls 10 sewn in this manner, the stretchable portion 16 is provided in the center of the collar 15 and the upper back body 32 in the body width direction, and extends downward from the upper end of the collar 15. Furthermore, the protruding portion 16b of the stretchable portion 16 constitutes the portion of the collar 15 from the seam line 36a between the left front body 30 and the upper back body 32 to the seam line 36c between the right front body 31 and the upper back body 32. Therefore, when the armholes 13a at the base of the pair of sleeves 14 are pulled to the left and right, the collar 15 including the seam portion 16a of the back portion 13 can be stretched in the body width direction (circumferential direction).

[0040] Generally, when putting on or taking off this type of coveralls 10, the wearer 1 secures a space between the torso and the armhole 13a with the left and right legs inserted into the pair of leg parts 22, respectively, and inserts and removes the arms into and from the sleeve parts 14 through the armhole 13a. If the stretchable part 16 is not provided, it is difficult to stretch the collar part 15 including the back part 13, so that it is extremely difficult to secure a space between the torso and the armhole 13a. In contrast, the coveralls 10 of this embodiment are provided with the stretchable part 16 having the protruding part 16b constituting a part of the collar part 15 and the sewn part 16a constituting a part of the back part 13, so that a part of the collar part 15 and a part of the back part 13 can be stretched. Therefore, it is easy to secure a space between the torso and the armhole 13a, and it is easy to insert and remove the arms into and from the sleeve parts 14 through the armhole 13a.

[0041] The coveralls 10 configured in this manner have the following features.

[0042] The coveralls 10 have a protruding portion 16b constituting a part of the collar 15 and a sewn portion 16a constituting a part of the back 13, and are provided with an elastic portion 16 for allowing the collar 15 to stretch in the circumferential direction. As a result, when putting on or taking off the coveralls 10, a part of the collar 15 and a part of the back 13 can be stretched by the elastic portion 16. Therefore, when putting on the coveralls 10, the armholes 13a can be separated from the torso of the wearer 1, so that the action of inserting the hands into the armholes 13a and pulling up the whole coveralls 10, especially the top 12, from below can be easily performed. Therefore, the coveralls 10 can be easily put on. Furthermore, when taking off the coveralls 10, the elbows can be easily removed from the armholes 13a. Therefore, the coveralls 10 can be easily taken off.

[0043] In this way, even if coveralls 10 are sewn for the most part with a relatively strong and durable material from a safety standpoint and have little space between the body and the fabric, it is easy to put arms in and out of sleeves 14 through armholes 13a, making it easy to put on and take off. In other words, coveralls 10 of this embodiment can achieve both improved ease of putting on and taking off and ensured durability by using elasticized parts 16 made of a stretch material and parts other than elasticized parts 16 made of a durable material.

[0044] The stretchable portion 16 is provided at the center in the width direction of the collar 15 and the back 13. More specifically, the protruding portion 16b of the stretchable portion 16 constitutes the portion of the collar 15 from the seam line 36a between the left front body 30 and the upper back body 32 to the seam line 36c between the right front body 31 and the upper back body 32. The sewn portion 16a of the stretchable portion 16 extends to a portion corresponding to the shoulder blades of the wearer 1. This configuration ensures that the stretchable portion 16 can stretch to a sufficient length, so that when putting on or taking off the coveralls 10, the arms can be easily and reliably inserted and removed from the sleeves 14 through the armholes 13a.

[0045] The stretchable portion 16 is made of a second fabric that is more stretchable than a first fabric that constitutes the remaining portion other than the stretchable portion 16. This allows a portion of the collar portion 15 and a portion of the back portion 13 to be reliably stretched by the stretchable portion 16, so that when putting on or taking off the coveralls 10, the arms can be easily and reliably inserted and removed into the sleeves 14 through the armholes 13a.

[0046] Other embodiments and various modifications of the present invention will be described below, but in these descriptions, points that are not particularly mentioned are the same as those in the first embodiment. In the drawings referred to below, the same elements as those in the first embodiment are given the same reference numerals.

[0047] Second embodiment 6, the coveralls 10 according to the second embodiment differ from the coveralls 10 of the first embodiment in that the sewn part 16a of the stretchable part 16 is extended to the lower end of the upper back body 32. In other words, the height dimension of the sewn part 16a is set to 100% of the back length H of the back part 13.

[0048] The upper back body 32 is composed of an upper left back body 32A sewn to the left front body 30 and the lower left back body 33, and an upper right back body 32B sewn to the right front body 31 and the lower right back body 34. The dimension in the body width direction of the sewn part 16a of the stretchable part 16 gradually decreases from the top to the bottom. The edges of the upper left back body 32A and the upper right back body 32B are sewn to both side edges of the sewn part 16a. The lower end of the sewn part 16a is sewn to the upper end center of the lower left back body 33 and the lower right back body 34.

[0049] In the coveralls 10 of the second embodiment configured in this manner, the stretchability in the body width direction due to the stretchable parts 16 can be further improved compared to the coveralls 10 of the first embodiment. Therefore, when putting on or taking off the work clothes 10, the length of stretch in the body width direction can be secured, so that the arms can be easily and reliably inserted and removed into the sleeve parts 14 through the armholes 13a.

[0050] Third embodiment 7 and 8, the coveralls 10 according to the third embodiment differ from the first embodiment in that the collar 15 is integral with the upper back body 32, and the entire upper back body 32 is made up of the stretchable part 16. In other words, the entire collar 15 is also made up of the stretchable part 16.

[0051] The left front torso covering part 30a of the left front body 30 is configured to cover the left half of the front torso of the wearer 1 from the chest down. The right front torso covering part 31a of the right front body 31 is configured to cover the right half of the front torso of the wearer 1 from the chest down. In other words, the left front body 30 forms the lower part of the left front portion of the back portion 13. The right front body 31 forms the lower part of the right front portion of the back portion 13.

[0052] The upper back body 32 extends from the back side of the back portion 13 to the front side, and is configured to cover the back portion and the upper part of the front portion. In other words, the upper back body 32 constitutes the back portion of the back portion 13, the upper part of the left front portion, and the upper part of the right front portion. This upper back body 32 is sewn to the left front body 30, the right front body 31, the lower left back body 33, and the lower right back body 34. Cylindrical sleeves 14 are sewn to the armholes 13a on both sides formed by this sewing.

[0053] A collar 15 is integrally formed on the upper back body 32. Similar to the collar 15 of the first embodiment, this collar 15 is C-shaped with an open front side when viewed from above, and extends in the circumferential direction from the left side of the front opening 26 through the back side to the right side of the front opening 26.

[0054] The left front body 30 and the right front body 31 are formed from a non-stretchable material (first fabric) that is stronger and more durable than the fabric that constitutes the stretchable portion 16. The upper back body 32 is formed from a stretch material (second fabric) that is more stretchable than the fabric that constitutes the left front body 30 and the right front body 31. In other words, the entire upper back body 32 is formed from the stretchable portion 16. The sewn portion 16a of the stretchable portion 16 is the portion excluding the protruding portion 16b (collar portion 15). The protruding portion 16b of the stretchable portion 16 constitutes the entire collar portion 15.

[0055] In the coveralls 10 of the third embodiment configured in this manner, the entire upper back body 32 including the collar 15 is configured with the stretchable portion 16, so that the stretchability in the body width direction can be improved even more than that of the coveralls 10 of the second embodiment. Therefore, when putting on or taking off the work clothes 10, the length of stretch in the body width direction can be secured, so that the arms can be easily and reliably inserted and removed into the sleeves 14 through the armholes 13a.

[0056] (Fourth embodiment) 9 and 10, the coveralls 10 of the fourth embodiment differ from the first embodiment in that the left front body 30 and the upper back body 32, and the right front body 31 and the upper back body 32 are all connected via a yoke 40 that covers the shoulders of the wearer 1. In this case, the yoke 40 is configured to include a pair of yoke pieces 40a that form the left and right parts in order to secure a portion to which the sewn portion 16a of the stretchable portion 16 is sewn. The configuration using the yoke 40 can also be applied to the coveralls 10 of the second and third embodiments.

[0057] One of the pair of yoke pieces 40a is sewn to the left front body 30, the upper back body 32, and the sewn portion 16a, respectively. The other of the pair of yoke pieces 40a is sewn to the right front body 31, the upper back body 32, and the sewn portion 16a, respectively. Sleeve portions 14 are sewn to the pair of armholes 13a formed by these sewing operations.

[0058] In this way, even in the coveralls 10 in which the left front body 30 and the right front body 31 are sewn to the upper back body 32 via the yoke 40, the same functions and effects as those of the above embodiment can be obtained.

[0059] Fifth embodiment 11 and 12, the coveralls 10 of the fifth embodiment differ from the first embodiment in that the stretchable parts 16 are configured to be detachable from the upper back body 32 constituting the back portion 13 and the pair of front collar parts 15a constituting the collar portion 15. In this manner, the configuration that makes the stretchable parts 16 detachable can also be applied to the coveralls 10 of the second to fourth embodiments.

[0060] Specifically, the stretchable portion 16 is separate from the upper back body 32 constituting the back portion 13 and the pair of front collar portions 15a constituting the collar portion 14. The sewn portion 16a of the stretchable portion 16 and the upper back body 32, and the protruding portion 16b of the stretchable portion 16 and the pair of front collar portions 15a can be attached together with a line fastener 42, which is an example of an attachable / detachable member. However, the attachable / detachable member may be a hook-and-loop fastener or a point fastener, and can be changed as necessary as long as the configuration allows the stretchable portion 16 to be detachably attached to the upper back body 32 and the pair of front collar portions 15a.

[0061] The linear fastener 42 includes a pair of fastener tapes 43A, 43B including a number of fastener elements 43a, and a slider (not shown) for engaging and separating the fastener elements 43a. The fastener tape 43A is sewn from the upper end of one of the side edges 15b of the pair of front collars 15a, through the edge of the notch 32a of the upper back body 32, to the upper end of the other. The fastener tape 43B is sewn from the upper end of one of the pair of side edges 16c of the protruding portion 16b, through the edge of the sewn portion 16a, to the upper end of the other. As a result, seams 44 are formed between the fastener tape 43A and the pair of front collars 15a, and between the fastener tape 43A and the upper back body 32. Seams 45 are formed between the fastener tape 43B and the protruding portion 16b, and between the fastener tape 43B and the sewn portion 16a.

[0062] The fabric constituting the stretchable portion 16 is more susceptible to wear than the fabric constituting the front collar portion 15a and the upper back body portion 32. Therefore, if the stretchable portion 16 is configured to be detachable, when the stretchable portion 16 is worn or damaged, only the stretchable portion 16 can be replaced. This eliminates the need to replace the coveralls 10 itself, improving the convenience of the wearer. In addition, by preparing multiple types of stretchable portions 16 with different colors, the coveralls 10 can be customized as desired. This makes it possible to change the color according to the level of skill of the worker or according to the worker's preferences, improving convenience.

[0063] The present invention is not limited to the configurations of the above-described embodiments, and various modifications are possible.

[0064] For example, although the collar portions 15 are all stand-up collars with no fold-up, they may also be open collars with fold-up.

[0065] The elastic portion 16 may be formed of a fabric having less elasticity than the stretch material, or by pleats or gathers provided on a non-elastic fabric.

[0066] The left front body 30, right front body 31, upper back body 32, lower left back body 33, lower right back body 34, sleeve portion 14, collar portion 15 (front collar portion 15a), stretch portion 16, and line fastener 42 are each joined by sewing, but may also be joined by bonding with an adhesive (bond).

[0067] The work clothes may be composed of only the top 12, without the bottom garment 20. In this case, the lower end of the front opening 26 may be spaced above the lower end of the back portion 13. [Explanation of symbols]
