Abstract
Description
[Technical Field]
[0001] The present invention relates to work clothes with excellent fit that are used at various work sites. [Background technology]
[0002] Various types of work clothes are manufactured and used depending on the type of work, and known fabrics used to manufacture work clothes include woven fabrics (see, for example, Patent Document 1) and knit fabrics (see, for example, Patent Document 2).
[0003] Due to the differences in properties between woven and knitted fabrics, there are advantages and disadvantages to the manufacturing and production of workwear. Workwear made from woven fabrics retains its shape better than knitted fabrics, and it is easier to manufacture woven fabrics than knitted fabrics. For these reasons, woven fabrics are more commonly used than knitted fabrics for workwear. [Prior art documents] [Patent documents]
[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2008-208509 [Patent Document 2] Japanese Patent Application Laid-Open No. 2005-146484 Summary of the Invention [Problem to be solved by the invention]
[0005] As mentioned above, work clothes made from woven fabric do not lose their shape as easily as work clothes made from knitted fabric, and woven fabric is easier to manufacture than knitted fabric, but woven fabric is not stretchy and shrinks after repeated washing. In particular, trouser length tends to shrink significantly, so trousers are typically made longer than the wearer's legs during manufacturing, which can result in the trousers' legs hanging down, making it difficult to walk and potentially catching on external protrusions, creating a dangerous situation.
[0006] The object of the present invention is to provide work clothes in which a portion of the trousers made of woven fabric is formed from knit fabric, thereby making it possible to accommodate shrinkage of the knit fabric. [Means for solving the problem]
[0007] In order to achieve the above object, the invention described in claim 1 is characterized in that in work clothes in which the jacket and trousers are made of woven fabric and configured as one unit or separate pieces, the bottom part of the trousers is formed from knitted fabric, and the trouser hem has a leg strap that straddles the opening.
[0008] According to the invention described in claim 1, the bottom portion of the trousers is made of knit fabric, so even if the woven fabric portion of the trousers shrinks due to repeated washing and the length of the trousers becomes shorter, the bottom portion of the trousers made of the knit fabric has elasticity, so the bottom portion can stretch and make up for the shortened length of the trousers, i.e., the amount of shrinkage in the length of the trousers.
[0009] In addition, the leg strings are provided at the bottom of the trousers so as to straddle the opening, so that when putting on the trousers, the wearer can put his / her feet on the leg strings to pull and stretch the part made of the knit fabric.
[0010] The invention described in claim 2 is characterized in that the collar of the jacket described in claim 1 is a collar that can be raised up and is made of knit fabric, and when the collar is raised up, the opposing left and right sides are provided with closing means, so that when the opposing left and right sides are closed, it becomes tubular in height to cover at least the face.
[0011] According to the invention described in claim 2, by raising the collar of the jacket and closing the opposing left and right edges, the tubular collar covers the face and neck, thereby protecting the worker's face and neck from sparks and thin iron fragments when performing work that involves flying sparks and thin iron fragments, such as welding or cutting metal. [Effects of the Invention]
[0012] As described above, with the work clothes of the present invention, even if the woven fabric portion of the trousers shrinks due to repeated washing and the length of the trousers becomes shorter, the portion of the trousers made of the knit fabric can stretch and make up for the shortened length of the trousers, i.e., the amount of shrinkage in the trousers' length. Therefore, the trouser length can be manufactured to fit the wearer's leg length, resulting in work clothes that are easy to work in. [Brief explanation of the drawings]
[0013] [Figure 1] 1 is a front view showing trousers in a work suit according to the present invention. FIG. [Figure 2] This is an explanatory diagram showing the state in which the woven fabric of the pants has shrunk due to repeated washing, resulting in the pants length being shortened to the maximum. [Figure 3] 1 is a front view showing a jacket in the work clothes according to the present invention. [Figure 4] This is an explanatory diagram showing the state in which the collar of the jacket is raised and the tubular collar covers the face and neck. DETAILED DESCRIPTION OF THE INVENTION
[0014] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the work clothes according to the present invention will be described in detail below with reference to the drawings. Figures 1 to 3 show an example of an embodiment of the work clothes according to the present invention, in which Figure 1 is a front view showing the trousers of the work clothes in this example, Figure 2 is an explanatory diagram showing the state in which the woven fabric portion of the trousers has shrunk due to repeated washing, resulting in the trousers being as short as possible, Figure 3 is a front view of the jacket of the work clothes in this example, and Figure 4 is an explanatory diagram showing the state in which the collar of the jacket has been raised and the tubular collar has covered the face and neck.
[0015] In this example, work clothes 1 are composed of pants 2 and a jacket 3 which are separate pieces. In this example, the trousers 2 have a bottom hem portion 4 made of knit fabric. The length L1 of the bottom hem portion 4 must be a length that allows stretch beyond the shrinkage L2 of the trouser length when the woven fabric portion of the trousers 2 shrinks with repeated washing of the trousers 2, resulting in the trouser length being shortened to its maximum. Although it depends on the type of fiber material of the knit fabric, the length L1 of the trouser bottom portion 4 that allows stretch to reliably accommodate the shrinkage L2 of the trouser length is preferably 1 / 2 to 1 / 3 of the crotch length.
[0016] In this example, the trouser bottom 5 is provided with a leg string 6 that straddles the opening of the trouser bottom 5.
[0017] The outerwear 3 in this example has a collar 7 made of knit fabric that can be raised. The opposing left and right edges 7a, 7b located on the front of the collar 7 are provided with closing means 9 that closes the opposing left and right edges 7a, 7b, so that when the collar 7 is raised and the opposing left and right edges 7a, 7b are closed, it forms a cylindrical shape that is tall enough to cover at least the wearer's face (see Figures 3 and 4).
[0018] The closing means 8 for closing the opposing left and right sides 7a, 7b of the collar 7 is a strip zipper 9. In this example, the strip zipper for closing the front opening of the jacket 3 is used as an extension. Furthermore, the closing means 8 is not particularly limited, and may be, for example, a hook-and-loop fastener.
[0019] The woven and knit fabrics used in the workwear 1 are not limited to any particular type of fiber, and may be selected depending on the type of work being performed by the worker, such as cotton, polyester, nylon, rayon, acrylic, modacrylic, aramid, polyurethane, or wool. The fibers used in the woven and knit fabrics may be the same or different.
[0020] In this example, the work clothes 1 are made up of the trousers 2 and the jacket 3, which are separate pieces, but they may also be made up as an integrated piece.
[0021] According to the work clothes 1 configured in this manner, the bottom hem portion 4 of the trousers 2 is made of knit fabric. Therefore, even if the woven fabric portion of the trousers 2 shrinks due to repeated washing and the trouser length becomes shorter, the bottom hem portion 4 made of knit fabric has elasticity, so it can stretch and make up for the shortened length of the trousers, i.e., the shortened length L2 of the trousers.
[0022] The trouser hem 5 is provided with a leg string 6 that straddles the opening of the trouser hem 5, so that when putting on the trousers 2, the wearer can pull and stretch the hem side portion 4 by putting their feet on the leg string 6, and the hem side portion 4 of the trouser hem 5 can reliably cover and protect the wearer's ankles.
[0023] In this example, the collar 7 of the jacket 3 is a collar that can be raised up and is made of knit fabric, and when the collar is raised up, the opposing left and right edges are provided with closing means, so that when the opposing left and right edges are closed, the collar becomes tubular and tall enough to cover at least the face.The collar 7 of the jacket 3 is made of knit fabric and has a shape that can be raised up, and when the opposing left and right edges 7a, 7b are provided with closing means 8, the collar forms a tubular shape that can cover at least the wearer's face when the opposing left and right edges 7a, 7b are raised and closed with the closing means 8.Therefore, when the collar 7 is raised and the opposing left and right edges 7a, 7b are closed, the tubular collar 7 covers the face and neck, and can protect the worker's face and neck from sparks when working in which sparks fly, such as when welding or cutting metal.
