Description

The present invention relates to work clothes with good work performance.

Work clothes are widely worn for various types of work. The present applicant has proposed work clothes using stretch fabric in order to allow the wearer of the work clothes to move smoothly without interfering with the movement of the wearer (Patent Document 1). In addition, the applicant has divided the rear sleeve into three parts: the back part of the shoulder which corresponds to the area from the upper back to the shoulder, the back part of the upper arm which corresponds to the area from the shoulder joint to the elbow joint, and the back part of the forearm which corresponds to the area from the elbow joint to the wrist. We have proposed work clothes that are divided into 3D parts and sewn, so that the inner edge of the shoulder blade, the back side of the shoulder base, and the back side of the elbow each have a rounded shape that bulges outward (patented). Reference 2).

Patent No. 2791624 Japanese Patent Application Publication No. 2002-38322

However, conventional work clothes do not allow the worker to, for example, round the back of the body so that the shoulder blades are apart from each other, bring the elbow joints out to the front of the body, or extend the arms forward or upward. During movement, there was a feeling of tightness in the back shoulders and back of the arms, and further improvements were needed. In addition, if there are many sewing points, it is disadvantageous in terms of productivity of work clothes.

In order to solve the above-mentioned problems, the present invention provides work clothes that have a reduced feeling of tightness, are comfortable to wear, and have good productivity.

In one aspect, the work clothes of the present invention include:
A front yoke part, a front outer sleeve part extending from the front yoke part, a rear yoke part, and a rear outer sleeve part extending from the rear yoke part are connected to each other at seams on the left and right sides of the body, respectively. It is made of a single piece of fabric,
The rear yoke portions of the left and right sides of the body are sewn together, and include a back seam line along the length of the body;
The warp threads of the back yoke part and the back outer sleeve part of the left and right body parts are inclined from bottom to top away from the back seam line.

In the work clothes of the present invention, the front yoke part, the front outer sleeve part, the back yoke part, and the back outer sleeve part are formed of a single piece of seamless fabric for each of the left and right sides of the body, The warp threads of the rear yoke portion and the rear outer sleeve portion of the left and right body parts are inclined from bottom to top and away from the back seam line. Therefore, the fabric stretches well from the back shoulder area to the back of both arms, allowing the wearer to, for example, round the back of the body so that the shoulder blades are apart from each other, or bring the elbow joints out to the front of the body. It is possible to provide work clothes that are comfortable to wear by suppressing the feeling of stiffness in the back shoulders and the back of the arms during movements such as stretching the arms forward or upward.
In addition, in the present invention, the front yoke part, the front outer sleeve part, the back yoke part, and the back outer sleeve part are formed from one piece of seamless fabric, so sewing can be simplified. Productivity of work clothes can be increased.

FIG. 1A is a schematic back view of work clothes in an embodiment of the present invention, and FIG. 1B is a partially enlarged view of FIG. 1A. FIG. 2 is a schematic front view of the work clothes shown in FIG. 1. FIG. 3 is a developed view of one side (left half of the body) of the sleeves, front and back body, etc. of the work clothes shown in FIGS. 1 and 2. FIG. 4 is a schematic explanatory diagram of the fabric used to sew the work clothes of FIG. 1. FIG. 5 is a schematic rear view of conventional work clothes. FIG. 6 is a schematic front view of the work clothes shown in FIG. 5.

The work clothes of the present invention are made by cutting a woven fabric into a predetermined shape and sewing the obtained fabric pieces together. Woven fabrics have good dimensional stability, high strength, high abrasion fastness, and high washing resistance, so they are often used for work clothes.

The work clothes of the present invention include a front yoke part that covers part or all of the chest, a front outer sleeve part that extends from the front yoke part, a back yoke part that covers part or all of the back shoulder part, and the front yoke part that covers part or all of the back shoulder part. A rear outer sleeve portion extending from the rear yoke portion is formed of one piece of fabric for each of the left and right body halves. These fabric pieces have no seams. Therefore, sewing can be simplified. Further, the warp threads are continuous from the back yoke part to the front yoke part, and there is no seam at the shoulder line. Therefore, the design of work clothes is better than if there were seams on the shoulders. In addition, since there are no seams at the shoulder line, you won't feel uncomfortable even if you put something on your shoulder, and you won't have any accidents due to it fraying or fraying when it gets caught. Therefore, the work clothes of the present invention have good design, durability, and safety.

Note that the shoulder line generally refers to the "stitching line" created when the front body and back body are sewn together above the shoulders, but in the present invention, the shoulder line is defined by the front yoke part, front outer sleeve part, and back yoke part. Since the front yoke part and the back outer sleeve part are formed of a single piece of seamless fabric, the "shoulder line" in the present invention refers to an imaginary line corresponding to the above-mentioned "stitch line", and the front yoke part This is an imaginary boundary line between the rear yoke and the rear yoke.

The work clothes of the present invention include a back seam line by sewing the back yoke part of the left half of the body and the back yoke part of the right half of the body to each other. The back sewing line is oriented in the length direction and is on the back center line that symmetrically bisects the work clothes. The warp threads of the back yoke part and the back outer sleeve part of the left and right halves of the body are respectively inclined from the bottom to the top of the work clothes so as to move away from the back seam line. That is, the warp threads of the back yoke part and the back outer sleeve part of the right half of the body and the warp threads of the back yoke part and the back outer sleeve part of the left half of the body move away from each other as they go from the bottom to the top of the work clothes. In the present invention, "upper" and "lower" are respectively defined based on the state of wearing work clothes. That is, "upper" refers to the upper side in the length direction, and "lower" refers to the lower side in the length direction.

A woven fabric composed of warp and weft yarns is difficult to stretch in the warp direction (the direction in which the warp yarns are oriented) and the weft direction (the direction in which the weft yarns are oriented). Although it stretches slightly in the weft direction compared to the warp direction, it cannot be said that it stretches easily.On the other hand, woven fabrics stretch easily in the diagonal direction (bias direction). In particular, the positive bias direction inclined at 45° or −45° with respect to the warp and weft is easy to stretch. Therefore, as mentioned above, in the work clothes of the present invention in which the warp threads of the back yoke part and the back outer sleeve part are inclined from bottom to top and away from the back seam line, the fabric constituting the work clothes is made of so-called stretch material. Even if it is not, the back yoke part and the back outer sleeve part can easily stretch in both the vertical direction (body length direction) and the left and right direction (shoulder width direction). Therefore, the work clothes of the present invention can easily follow the movements of the wearer's back, shoulders and arms, allow smooth movements of the wearer without hindering them, and are comfortable to wear.

The angle of inclination of the warp threads of the back yoke part and the back outer sleeve part is preferably 30° or more for the right side of the body, with the back seam line as the reference line, from the viewpoint of improving the elasticity of the woven fabric that follows the movements of the wearer. The angle is 60°, more preferably 40° to 50°, particularly preferably 45°. For the left side of the body, the angle is preferably -30° to -60°, more preferably -40° to -50°, particularly preferably -45°, using the back seam line as the reference line.
In addition, if the inclination angle is set within the above range and the warp threads of the front yoke are cut in the same direction as the length of the garment, it will not only be comfortable to wear, but also look better when viewed from the front. You can create work clothes with good design.

It is preferable that the absolute value of the inclination angle of the warp in the rear yoke portion of the left half of the body is equal to the absolute value of the inclination angle of the warp in the rear yoke portion of the right half of the body, with the back sewing line as a reference line. Further, the warp threads of the back yoke part and the back outer sleeve part of the left half of the body and the warp threads of the back yoke part and the back outer sleeve part of the right half of the body are arranged symmetrically with respect to the back center line as an axis of symmetry. and preferable. With these aspects, the stretchability in both the vertical and horizontal directions becomes symmetrical, resulting in work clothes that are comfortable to wear and have a good design when viewed from behind.

Of the fabric pieces forming the front yoke part, the front outer sleeve part, the back yoke part, and the rear outer sleeve part, the part consisting of the front yoke part and the front outer sleeve part, and the rear yoke part and the rear outer sleeve part. The fabric piece is cut so that the front outer sleeve part and the back outer sleeve part are offset toward the front outer sleeve part so that the part consisting of preferable. By doing so, the front outer sleeve portion and the back outer sleeve portion can easily expand and contract in the direction from the shoulder to the cuff. For the same reason, it is more preferable that the other end of the sleeve top line is located at the center of the cuff side side of the fabric piece.

In the work clothes, the front inner sleeve section is arranged under the front outer sleeve section, the back inner sleeve section is arranged under the back outer sleeve section, the lower part of the front body is arranged below the front yoke section, and the front inner sleeve section is arranged below the front outer sleeve section. It is preferable that the warp threads of the lower part of the back body, which are arranged below the back yoke part, are arranged along the length direction of the garment. This improves the design of work clothes.

In the work clothes, it is preferable that the lower part of the back body of the left half of the body and the lower part of the back body of the right half of the body are formed of a single piece of seamless fabric. This results in work clothes with good design.

The work clothes of the present invention include a work clothes top. The work clothes of the present invention are not limited to the upper work clothes, but may also be work coveralls in which the upper work clothes (upper clothes part) and the lower work clothes (lower clothes part) are integrally connected. In this case, the lower garment section is not particularly limited and may be one used for ordinary coveralls.

The raw materials for the yarn used in the woven fabric constituting the work clothes of the present invention include natural fibers, synthetic fibers, and both of these fibers. The yarn used in the textile fabric may be made of any material, including, for example, 100% natural fiber spun yarn, 100% synthetic fiber spun yarn, and blended yarn of natural fibers and synthetic fibers. , a spun yarn of 100% cotton yarn, a spun yarn of 100% polyester fiber, or a blended yarn of cotton and polyester fiber is preferable. The woven fabric is a fabric containing these threads. In the blended yarn of cotton and polyester fibers, the ratio of cotton to polyester fibers is, for example, 10 to 90% by mass of cotton and 90 to 10% by mass of polyester fibers. The woven fabrics of these yarns are washable and can be used repeatedly.

The textures of the textiles constituting the work clothes of the present invention include plain weave, twill weave, satin weave, modified plain weave, modified twill weave, modified satin weave, variable weave, patterned weave, single layer weave, and double weave. , multiple weave, warp pile weave, weft pile weave, twine weave, etc. Among these, plain weave and twill weave are preferred. The mass per unit area (fabric weight) of the fabric is preferably 50 to 500 g/m ² , more preferably 100 to 450 g/m ² , and even more preferably 140 to 400 g/m ² .

Hereinafter, specific examples of the work clothes of the present invention will be explained using the drawings. In each drawing, the same reference numerals indicate the same parts.

FIG. 1A is a schematic back view of work clothes according to an embodiment of the present invention, FIG. 1B is a partially enlarged view of FIG. 1A, and FIG. 2 is a schematic front view of the work clothes shown in FIG. 1A. be.

As shown in FIGS. 1 and 2, the work clothes 1 include front yoke parts 2a and 3a, front outer sleeve parts 2b and 3b, back yoke parts 2c and 3c, back outer sleeve parts 2d and 3d, and front inner sleeve part 4a. , 4b, back inner sleeve parts 5a, 5b, front lower body parts 6a, 6b, back body lower parts 7a, 7b, collar 9, placket 10, hem belt 11, and cuffs 12.

FIG. 3 is a developed view of the sleeve, front and back body, etc. of the left half of the workwear 1 shown in FIGS. 1 and 2, with the back center line 13 as an axis of symmetry. In FIG. 3, 30b is a shoulder line, and 40b is a sleeve top line. 50b is a line consisting of the shoulder line 30b and the upper sleeve line 40b. 45b is the tip of the shoulder, one end of the shoulder line 30b on the sleeve side, and also one end of the upper sleeve line 40b. 41b is the other end of the sleeve top line 40b, located approximately at the center of the cuff side side 3e of the fabric piece 3. 35b is an extension of the shoulder line 30b, and 36b is the tip of the extension 35b, which is on the side 3e of the fabric piece 3 on the cuff side.

As shown in FIG. 3, the front yoke part 3a and the rear yoke part 3c are seamless at the shoulder line 30b, and the front outer sleeve part 3b extends from the front yoke part 3a, and the rear part extends from the rear yoke part 3c. The outer sleeve portion 3d has no seam at the upper sleeve line 40b. Moreover, the front yoke part 3a and the front outer sleeve part 3b, and the back yoke part 3c and the back outer sleeve part 3d have no seams at the bases of the body and sleeves, respectively. That is, the front yoke part 3a, front outer sleeve part 3b, back yoke part 3c, and back outer sleeve part 3d of the left half of the body are formed of one piece of seamless fabric 3. Similarly, for the right half of the body, the front yoke portion 2a, front outer sleeve portion 2b, back yoke portion 2c, and back outer sleeve portion 2d are formed of one seamless piece of fabric 2.
Further, the lower back body part 7a of the right half of the body and the lower back body part 7b of the left half of the body are also formed of one piece of seamless fabric 7.

As shown in FIG. 3, in the fabric piece 3, the line 50b is placed at the shoulder end 45b such that the other end 41b of the sleeve top line 40b is located closer to the front outer sleeve portion 3b than the tip 36b of the extension line 35b. It's bent. The other end 41b of the sleeve top line 40b is located approximately at the center of the side 3e on the cuff side. In this way, the portion of the fabric piece 3 consisting of the front yoke portion 3a and the front outer sleeve portion 2b and the portion consisting of the rear yoke portion 3c and the rear outer sleeve portion 2b are connected to the shoulder line 30b and its extension. If the fabric piece 3 is cut so that the front outer sleeve part 2b and the back outer sleeve part 2b are deviated toward the front outer sleeve part 2b so as not to be symmetrical about the line 35b, the front outer sleeve part 3b and the rear outer sleeve portion 3d can easily expand and contract in the direction from the shoulder to the cuff.

In the example shown in FIG. 3, specifically, the angle between the shoulder line 30b and the back center line 13 is set to approximately 74°, and the front outer sleeve portion 3b and the rear outer sleeve portion 3d are extended from the shoulder tip 45b to the front outer sleeve portion 3b and the back outer sleeve portion 3d. It is deviated by 10 degrees toward the sleeve portion 3b side, and the angle between the sleeve upper line 40b and the back core line 13 is set to approximately 84 degrees.

In the example of conventional work clothes shown in FIGS. 5 and 6, the warp threads 160a of the back yoke parts 20c and 30c and the back outer sleeves 20d and 30d are arranged in the same direction as the body length direction X, especially as shown in FIG. has been done. On the other hand, as shown in FIG. 1, in the work clothes 1 according to one embodiment of the present invention, the warp threads 16a and 16b of the back yoke parts 2c and 3c and the back outer sleeves 2d and 3d are arranged at the back seam line from bottom to top. It is tilted away from 8. Therefore, the warp threads 16a of the back yoke part 2c and the back outer sleeve part 2d of the right half of the body, and the warp threads 16b of the back yoke part 3c and the back outer sleeve part 3d of the left half of the body move away from each other from the bottom to the top. For example, as shown in FIG. 1, it is inclined in the direction toward the back center line 13 passing through the back sewing line 8 from a line 50b including the shoulder line 30b and the upper sleeve line 40b having one end at the shoulder tip. In the conventional work clothes 100 shown in FIGS. 5 and 6, 20a and 30a are front yoke parts, 20b and 30b are front outer sleeve parts, 40a and 40b are front inner sleeve parts, and 50a and 50b are front inner sleeve parts, respectively. 60a and 60b are the lower parts of the front body, 70a and 70b are the lower parts of the back body, 90 is the collar, 101 is the placket, 110 is the hem belt, 120 is the cuff, and 130 is the back core.

As shown in FIG. 1, in the work clothes 1, the warp threads 16a and 16b are arranged so as to be inclined from bottom to top and away from the back seam line 8, as shown in FIG. It has better stretchability in both the vertical and horizontal directions than conventional work clothes in which the warp yarns 160a and 160b are oriented in the same direction as the length direction. Therefore, when the wearer, for example, rounds the back of the body so that the shoulder blades move away from each other, brings the elbow joint out to the front of the body, or extends the arm forward or upward, the dorsal shoulder And the feeling of tightness on the back of the arm is reduced.

As shown in FIG. 1B, in the work clothes 1, the inclination angle θ1 of the warp threads 16a of the back yoke part 2c and the back outer sleeve part 2d of the right half of the body is 45 degrees, with the back sewing line 8 or the back center line 13 as a reference line. The inclination angle θ2 of the warp threads 16b of the rear yoke portion 3c and the rear outer sleeve portion 3d of the left half of the body is −45°, and the absolute values of θ1 and θ2 are equal. Therefore, the elongation in both the up-down direction and the left-right direction becomes bilaterally symmetrical, resulting in a good wearing feeling. Further, when the absolute values of θ1 and θ2 are 45°, the orientation direction of the warp threads in the front yoke parts 2a, 3a and the front outer sleeve parts 2b, 3b becomes the same direction as the garment length direction X, and when viewed from either the front or the rear. This also makes for work clothes with good design.

As shown in FIGS. 1 and 2, in the work clothes 1, the warp threads of the front inner sleeve parts 4a, 4b, the back inner sleeve parts 5a, 5b, the front lower body parts 6a, 6b, and the back body lower parts 7a, 7b are Moreover, there is no seam extending in the length direction below the back seam line 8, and the lower back body 7a and the lower back body 7b are formed by one piece of seamless fabric 7. It is formed. Therefore, the design of the work clothes 1 is very good.

FIG. 4 is a schematic explanatory diagram of the woven fabric used for sewing the work clothes 1. In FIG. 4, 51 is a warp, and 52 is a weft. 53 and 54 each point to a positive bias direction inclined at 45° with respect to the warp and weft. The elongation rate in the positive bias direction of the textile material used for sewing the work clothes 1 is preferably 5 to 30%, more preferably 7 to 20%, and still more preferably 7 to 12%. For example, the elongation rate in the positive bias direction of the fabric used for sewing the work clothes 1 using a so-called general-purpose TC blend yarn (35% cotton, 65% polyester) is preferably 5 to 30%, More preferably 7 to 20%, still more preferably 7 to 12%. Note that the elongation rate (%) can be measured by the method described in the Examples below.

The present invention will be explained in more detail below with reference to Examples. Note that the present invention is not limited to the following examples. The elongation rate of the woven fabric used for sewing the work clothes of Example 1 is a value measured by the following method.

[Elongation rate of textile fabric in positive bias direction]
The elongation rate of the woven fabric used for sewing work clothes was calculated in accordance with method B (constant load method for woven fabrics) of "JIS L 1096 Fabric Testing Methods for Woven and Knitted Fabrics".
Specifically, three test pieces with a width of 50 mm and a length of 300 mm were prepared, and after setting them in a tensile tester so as to grasp the entire width, marks were made at 200 mm intervals (L0) and a load of 14.7 N was applied. After holding for 1 minute, the length between the marks (L1) was measured, and the elongation rate (%) was determined by the following formula. In addition, when adjusting the test piece, the length direction of the test piece and the positive bias direction (45°) of the woven fabric were made to match.
Elongation rate (%) = {(L1-L0)/L0}×100

(Example 1)
Fabric with a mass of 200 g/m ² with a twill weave structure, using a blended yarn (meter count 15) of 30% by mass of cotton and 70% by mass of polyester for the warp and 100% polyester yarn (300 denier) for the weft. manufactured the fabric. The elongation rate of the woven fabric in the positive bias direction was 8%. Using this fabric, work clothes shown in FIGS. 1 to 3 were sewn. The obtained work clothes were L size and weighed about 610 g each. When wearing this work uniform and performing various tasks, for example, rounding the back of the body so that the shoulder blades are separated from each other, bringing the elbow joints out to the front of the body, or stretching the arms forward or upward. It was confirmed that the wearer felt comfortable wearing it without feeling tight during such operations, and that the wearer could work smoothly without interfering with the wearer's movements.

The work clothes of the present invention are suitable as upper garments for various types of work such as civil engineering, construction, work inside and outside of factories, indoor work, and hospital work.
