Description

[Technical Field]

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

[0002] Pants designed to improve the comfort of wearers who work in the medical field have been proposed. For example, one such pair of pants has a double layer structure consisting of an outer fabric and an inner fabric, from the knees to the hem, and at least a portion of the inner fabric is provided with a means for adjusting the pressure on the wearer's lower legs, making it possible to adjust the pressure on the wearer's lower legs depending on the situation (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2015-214784 Summary of the Invention [Problem to be solved by the invention]

[0004] However, as mentioned above, in the above-mentioned conventional trousers, the means for adjusting the pressure on the trousers is only provided in the part from the knee to the hem of the trousers. Therefore, for example, when the wearer tries to bend forward, the part on the back side of the trousers is difficult to stretch, making it difficult for the wearer to bend forward or to maintain a bent-over position, and there is room for improvement in terms of improving the wearer's ease of movement.

[0005] The present invention has been made in view of the above, and has an object to provide clothing that enables the wearer to move more easily. [Means for solving the problem]

[0006] The garment described in claim 1 is a garment worn by a wearer, and comprises at least a lower garment having a front body and a back body, and is provided with a first stretchable section provided in the vicinity of the upper end of the back body, a tightening section provided across the entire upper end of the lower garment for tightening the garment around the wearer, and second stretchable sections provided on both sides of the widthwise end of the first stretchable section in the back body, wherein the amount of stretch of the first stretchable section in the vertical direction is greater than the amount of stretch of the back body in the vertical direction, the first stretchable section is provided adjacent to the tightening section so as not to overlap with the tightening section, and the second stretchable section is provided adjacent to the tightening section so as not to overlap with the tightening section. The tightening portion comprises a first tightening portion made of a string member and housed within the upper end of the lower garment so that a portion of the first tightening portion is exposed to the outside, and a second tightening portion made of a rubber member and housed within the upper end of the lower garment so that the entire second tightening portion is not exposed to the outside. [Effects of the Invention]

[0009] According to the garment of claim 1, a first stretchable section is provided at or near the upper end of the back body, and the amount of vertical stretch of the first stretchable section is greater than the amount of vertical stretch of the back body, so that the first stretchable section can stretch in accordance with the movement of the wearer (especially a wearer engaged in medical work) while wearing the garment. Therefore, the wearer's ease of movement while wearing the garment is improved compared to when the first stretchable section is not provided. [Brief explanation of the drawings]

First, [I] the basic concept of the embodiment will be explained, then [II] specific contents of the embodiment will be explained, and finally, [III] modifications to the embodiment will be explained. However, the present invention is not limited to the embodiment.

[0012] [I] Basic Concept of the Embodiment First, the basic concept of the embodiment will be described. The embodiment generally relates to a garment worn by a wearer, which includes at least a lower garment having a front body and a back body.

[0013] Here, "wearer" refers to the person wearing the clothing, and includes workers in any workplace not limited to a specific industry or occupation, such as those engaged in medical, nursing, or care work. Furthermore, "clothing" refers to clothing worn by the wearer, and includes, for example, bottoms (e.g., trousers, shorts, skirts, etc.) and one-piece clothing. In the following embodiments, the case where clothing is applied to bottoms will be described.

[0014] [II] Specific details of the embodiment Next, specific details of the embodiment will be described.

[0015] (composition) First, the configuration of a garment according to an embodiment of the present invention will be described. FIG. 1 is a front view showing the configuration of a garment according to an embodiment of the present invention. FIG. 2 is a back view of the garment of FIG. 1. FIG. 3 is an enlarged view showing an upper portion of the garment of FIG. 2. In the following description, the X direction in FIG. 1 is referred to as the left-right direction or width direction (based on the direction as seen from the wearer (not shown), with the -X direction being the right direction and the +X direction being the left direction), the direction perpendicular to the Y direction in FIG. 4 (described later) is referred to as the front-to-back direction (the +Y direction being the front direction and the -Y direction being the rear direction), and the Z direction in FIG. 1 is referred to as the up-to-down direction (the +Z direction being the up direction and the -Z direction being the down direction). Furthermore, based on the center position of the garment in FIG. 1, the direction away from the garment is referred to as the "outside" and the direction towards the garment is referred to as the "inside." As shown in Figures 1 to 3, the garment 1 comprises a garment body 10, a first crotch opening / closing section (not shown), a second crotch opening / closing section 30, a first tightening section 40, a second tightening section (not shown), a gusset section 50, a right pocket section 61, and a left pocket section 62.

[0016] (Composition - clothing body) Returning to Fig. 1, the configuration of the garment body 10 will be described first. The garment body 10 is the basic structure of the garment 1, and is formed as a substantially hollow body capable of covering the lower body of the wearer, as shown in Figs. 1 and 2. For convenience of explanation, the garment body 10 will be described by dividing it into two regions as shown below.

[0017] That is, this garment body 10 comprises a front body 10a that covers the wearer's abdomen and a back body 10b that covers the wearer's buttocks. Of the front body 10a and back body 10b, the portion 11 that corresponds to the wearer's crotch is referred to as the "crotch portion 11," the portion 12 that corresponds to the wearer's crotch is referred to as the "crotch portion 12," and the portion 13 that corresponds to the wearer's crotch is referred to as the "crotch portion 13." Of the crotch portion 11, the portion 11a at and near the upper end that accommodates the first and second tightening portions 40 and 20 is referred to as the "accommodating portion 11a" (specifically, the portion formed by folding back and sewing together portions of the front body 10a and back body 10b). Furthermore, within the crotch portion 12, the portion 12a corresponding to the wearer's right crotch is referred to as the "right crotch portion 12a," and the portion 12b corresponding to the wearer's left crotch is referred to as the "left crotch portion 12b." Furthermore, within each of the right crotch portion 12a and the left crotch portion 12b, the portion 12c corresponding to the wearer's inner crotch is referred to as the "inner crotch portion 12c," and the portion 12d corresponding to the wearer's outer crotch is referred to as the "outer crotch portion 12d." Furthermore, the upper end of the crotch portion 11 is referred to as the waist opening portion 14, and the lower end of the crotch portion 12 is referred to as the hem opening portion 15. Furthermore, of the sides of the garment body 10, the side facing the wearer's skin is referred to as the "inner garment surface," and the side opposite the side facing the wearer's skin is referred to as the "outer garment surface."

[0018] Furthermore, the specific configuration of the garment body 10 is arbitrary, but in this embodiment, as shown in Figures 1 to 3, it has a first crotch side cutout 16, a second crotch side cutout 17, a crotch side cutout 18, and a support portion (not shown).

[0019] (Configuration - Garment body - First rise side cutout) Returning to Figure 1, the first crotch side notch 16 is a notch for assisting in putting on and taking off the garment 1 (particularly the crotch portion 11), and as shown in Figure 1, is formed in the inner portion in the left-right direction of the crotch portion 11 of the front body 10a, extending from the upper end to the lower end of the inner portion.

[0020] (Configuration - Garment body - Second rise side cutout) The second crotch side cutout 17 is a cutout for attaching the first stretchable section 70, the right side second stretchable section 81, and the left side second stretchable section 82, which will be described later, and is formed in the vicinity of the upper end of the back body 10b (specifically, the part adjacent to the storage section 11a), as shown in Figures 2 and 3.

[0021] The specific shape and size of the second rise-side cutout 17 are arbitrary, but are set as follows in this embodiment. That is, the shape of the second rise-side cutout 17 is set to an inverted concave shape (note that the shape of the portion of the second rise-side cutout 17 corresponding to the first stretchable section 70, which will be described later, is set to an approximately rectangular shape). However, this is not limited to this, and shapes other than an inverted concave shape may be used (for example, a rectangular shape may be used). The length (width) of the second rise-side cutout 17 in the left-right direction is set to be approximately the same as the length of the rise portion 11 in the left-right direction. The length (vertical direction) of the second rise-side cutout 17 is set to be shorter than the length of the rise portion 11 in the up-down direction (for example, it is set to be less than half the length of the rise portion 11 in the up-down direction).

[0022] (Composition - Garment body - Inseam side notch) 1, crotch-side cutout 18 is a cutout for attaching gusset 50, and is formed in the vicinity of the upper end of back body 10b (specifically, the portion adjacent to storage portion 11a) as shown in Figures 1 and 2. Specifically, as shown in Figure 4 described later, it is formed so that its planar shape is approximately diamond-shaped (however, it is not limited to this and may be formed into, for example, a rectangular, circular, or elliptical shape). Also, as shown in Figures 1 and 2, crotch-side cutout 18 is formed in inner crotch portions 12c of right crotch portion 12a and left crotch portion 12b of front body 10a and back body 10b, from the portion corresponding to the wearer's crotch to the portion corresponding to the lower end of the thigh.

[0023] (Composition - Garment body - Carrying part) The extension portion is intended to prevent the first crotch side opening / closing portion (specifically, the right attachment tooth portion described later, the left attachment tooth portion described later, etc.) from coming into contact with the wearer, and is provided on the right side of the first crotch side cutout 16 in the crotch portion 11 of the front body 10a, over approximately the entire length of the first crotch side cutout 16, and is connected to the right side portion of the first crotch side cutout 16.

[0024] The garment body 10 (specifically, the front and back pieces 10a, 10b) may be made of any material, but is preferably made of a material that allows the wearer to move easily. For example, the garment may be made of a known lightweight and stretchy woven or single-layer knit material, a known multi-layer knit material with a polyester outer layer and a cotton (or cupra) lining, or a combination of these. The grain direction of the garment body 10 (specifically, the front and back pieces 10a, 10b) may be any direction, but while in the embodiment it is set to run vertically, it may be set to run counter to the vertical direction. Here, "grain direction" means the direction in which the threads of the fabric are woven or knitted, and in the embodiments, it is explained as meaning the direction in which the warp threads are woven in the case of woven fabric, the vertical direction in which the threads are knitted in the case of warp-knitted fabric (for example, warp-knitted knit fabric, etc.), and the horizontal direction in which the threads are knitted in the case of weft-knitted fabric (for example, weft-knitted knit fabric, etc.).

[0025] (Configuration - 1st rise side opening / closing part) Next, the configuration of the first crotch opening / closing section will be described. The first crotch opening / closing section is an opening / closing section that allows the crotch portion 11 of the front body 10a (specifically, the first crotch cutout 16) to be freely opened and closed. This first crotch opening / closing section is configured using, for example, a known wire fastener for clothing (for example, a wire fastener made of resin or metal), and has a right coupling tooth portion, a left coupling tooth portion, and a slider portion (all not shown).

[0026] (Configuration - 1st crotch side opening / closing part - right side tooth part, left side tooth part) The right and left coupling teeth are portions that engage with and disengage from each other as the slider portion moves. Of these, the right coupling tooth is provided in a portion of the rise portion 11 near the right side of the first rise-side notch 16, over substantially the entire length of the first rise-side notch 16, and is connected to the rise portion 11 via a tape portion (not shown). Furthermore, the left coupling tooth is provided in a portion of the rise portion 11 near the left side of the first rise-side notch 16, over substantially the entire length of the first rise-side notch 16, and is connected to the rise portion 11 via a tape portion (not shown). Furthermore, a stop portion (not shown) is provided at the upper end of each of the right and left coupling teeth to prevent the slider portion from coming off the right and left coupling teeth.

[0027] (Configuration - First crotch opening / closing part - Slider part) The slider portion is a part for engaging and disengaging the right and left tooth portions, and is provided between the right and left tooth portions and connected to the left tooth portion by a fitting structure or the like.

[0028] (Configuration - 2nd rise side opening / closing part) Returning to Fig. 1, we next explain the configuration of second riser side opening / closing section 30. Second riser side opening / closing section 30 is an opening / closing section that allows rise portion 11 (specifically, first riser side cutout portion 16) to be opened and closed freely, and as shown in Fig. 1, includes attachment section 31 and attachment hole (not shown).

[0029] (Configuration - Second crotch opening / closing section - Mounting section) The attachment portion 31 is for attaching the right side of the first crotch side notch 16 of the crotch portion 11 to the left side of the first crotch side notch 16, and is constructed using, for example, a known clothing attachment device (such as a button), and is attached to the upper end of the outer surface of the clothing at the holding portion, as shown in Figure 1.

[0030] (Configuration - Second crotch opening / closing section - Mounting hole) The mounting hole is a through hole for mounting the mounting portion 31, and is provided at the upper end of the left side portion of the first rise-side cutout 16 in the rise portion 11.

[0031] (Configuration: 1st tightening part, 2nd tightening part) Next, the configurations of the first and second compressing portions will be described. The first and second compressing portions are configured to tighten the garment 1 (lower garment) around the wearer to prevent the garment 1 from slipping down. The first compressing portion 40 is configured, for example, using a known compressing member (e.g., a string member for clothing) whose amount of tightening can be adjusted by the wearer. As shown in FIG. 1 , the first compressing portion 40 is housed within the housing portion 11a of the crotch portion 11 so that only the longitudinal end of the first compressing portion 40 and its surrounding area are exposed to the outside. The second compressing portion is configured, for example, using a known compressing member (e.g., a rubber member for clothing) whose amount of tightening cannot be adjusted by the wearer. The entire second compressing portion is housed within the housing portion 11a of the crotch portion 11 so as not to be exposed to the outside, and a portion of the second compressing portion is fixed to the housing portion 11a by sewing or the like.

[0032] (Configuration - Gusset) Next, the structure of the gusset portion 50 will be described. Fig. 4 is a cross-sectional view taken along the line AA in Fig. 1, and is an enlarged view of the portion corresponding to the gusset portion 50. The gusset portion 50 is intended to provide roominess in the crotch portion 13 and the surrounding areas of the front body 10a and the back body 10b. The gusset portion 50 is made of a known gusset material having higher stretchability than the garment body 10 (e.g., higher stretchability in the left-right direction), and is provided in the crotch-side cutout 18. Specifically, as shown in Figs. 1 and 2, the gusset portion 50 is disposed over the entire second crotch-side cutout 17 and is fixed to the right crotch portion 12a and the left crotch portion 12b of the front body 10a and the back body 10b by sewing or the like.

[0033] Furthermore, the specific shape and size of this gusset portion 50 are arbitrary, but in this embodiment, as shown in Fig. 4, the planar shape of gusset portion 50 is set to be substantially the same shape (for example, diamond shape) as the planar shape of crotch-side cutout portion 18, and the size of gusset portion 50 (specifically, the length in the left-right, up-down, and front-to-back directions) is set to be slightly larger than the size of crotch-side cutout portion 18. This prevents the crotch sole of the wearer from being constricted by gusset portion 50 due to the wearer's movements while wearing the garment, and also prevents the wearer's crotch sole from becoming stuffy.

[0034] (Configuration: Right pocket, left pocket) Returning to FIG. 1 , the configurations of the right pocket 61 and the left pocket 62 will be described next. The right pocket 61 and the left pocket 62 are for storing items (not shown). Here, "items" refers to items to be stored in the right pocket 61 or the left pocket 62, and includes, for example, a medical PHS, a mobile phone, nursing care equipment, stationery, etc. As shown in FIG. 1 , the right pocket 61 is provided on the outer surface of the front body 10a in a portion corresponding to the wearer's right crotch, and the left pocket 62 is provided on the outer surface of the front body 10a in a portion corresponding to the wearer's left crotch. The right pocket 61 and the left pocket 62 are formed into a generally bag-like shape by, for example, fixing a known woven fabric material, which is substantially the same as that of the garment body 10, to the front body 10a by sewing or the like.

[0035] (Configuration - Structure that improves ease of movement) Next, we will explain the mobility-enhancing structure of the garment 1. The garment 1 according to the embodiment is provided with a mobility-enhancing structure that aims to improve the wearer's mobility when the wearer is wearing the garment 1 (hereinafter referred to as the "worn state"). The features of this mobility-enhancing structure in the embodiment are as follows:

[0036] (Configuration - Mobility Improvement Structure - First Feature) First, regarding the first feature of the structure for improving ease of movement, as shown in FIGS. 2 and 3, the garment 1 is provided with a first stretchable section 70.

[0037] (Configuration - Mobility Improvement Structure - First Feature - First Elastic Section) The first stretchable section 70 is a stretchable section. This first stretchable section 70 is formed separately from the garment body 10 and is made of, for example, a known stretchable material (e.g., a rib material, a mesh material, or a combination thereof (e.g., a mesh tape such as a flexible mesh)). The first stretchable section 70 is provided in the second crotch cutout 17 (i.e., provided in the vicinity of the upper end of the back body 10b). Specifically, as shown in FIG. 3, it is located in the left-right center of the second crotch cutout 17 and is connected to the crotch portion 11 of the back body 10b via a seam 72 (hereinafter referred to as the "first stretchable section seam 72").

[0038] Furthermore, the specific shape and size of the first stretchable portion 70 are arbitrary, but in this embodiment, they are set as follows. That is, as shown in FIG. 3, the shape of the first stretchable portion 70 is set to a substantially rectangular shape that extends substantially along the width direction in order to improve the manufacturability of the first stretchable portion 70. Furthermore, the left-right length (width) of the first stretchable portion 70 is set to be shorter than the left-right length of the back body 10b (specifically, the rise portion 11). (For example, the length may be set to be longer than half the left-right length of the rise portion 11, but this is not limiting, and the length may be set to be approximately the same as or shorter than half the left-right length of the rise portion 11.) Furthermore, the vertical length of the first stretchable portion 70 is set to be shorter than the vertical length of the rise portion 11. (For example, the length is set to be less than half the vertical length of the rise portion 11.)

[0039] Furthermore, the direction of the grain of the first stretchable section 70 is arbitrary, but in this embodiment, the direction of the grain of the first stretchable section 70 is set to be approximately along the vertical direction. However, this is not limiting, and for example, the direction of the grain of the first stretchable section 70 may be set to be not along the vertical direction. As an example, the direction of the grain of the first stretchable section 70 may be set to be outward (or inward) in the width direction as it extends downward.

[0040] Furthermore, the amount of stretch of the first stretchable section 70 is arbitrary, but in this embodiment, the amount of stretch of the first stretchable section 70 in the vertical direction is set to be greater than the amount of stretch of the back body 10b in the vertical direction. Specifically, it is desirable to set an amount that allows the first stretchable section 70 to stretch in accordance with the wearer's movements while wearing the garment. As an example, since this may vary depending on the size, shape, or type of material of the first stretchable section 70 and the back body 10b, it may be set based on experimental results, etc.

[0041] Furthermore, the first stretchable portion 70 may be disposed in any manner. In this embodiment, however, the widthwise end of the first stretchable portion 70 and the portion of the back body 10b corresponding to the top of the wearer's buttocks are disposed so that they are substantially aligned or are positioned widthwise outward of the aligned line. Specifically, as shown in FIGS. 2 and 3 , the right end of the first stretchable portion 70 is disposed to the right of the line corresponding to the top of the wearer's right buttock (or the top of the right knee), and the left end of the first stretchable portion 70 is disposed to the left of the line corresponding to the top of the wearer's left buttock (or the top of the left knee). This allows the first stretchable portion 70 to be stretched more effectively when the upper portion of the back body 10b is pulled downward by the top of the wearer's buttocks, compared to when the widthwise end of the first stretchable portion 70 and the portion corresponding to the top of the wearer's buttocks are positioned widthwise inward of the line.

[0042] While other specific configurations of the first stretchable portion 70 are optional, in this embodiment, as shown in FIG. 3 , the first stretchable portion 70 includes an outer stretchable portion 71 (e.g., the outer stretchable portion 71 is made of a ribbed material) and an inner stretchable portion (e.g., the inner stretchable portion is made of a mesh material) located inside the outer stretchable portion 71 (so-called double-layer structure) to prevent the wearer's underwear or skin from showing through the first stretchable portion 70. In this case, the configurations of the outer stretchable portion 71 and the inner stretchable portion are optional. For example, the mesh size, wire diameter, number, and color of the rib material constituting each of the outer stretchable portion 71 and the inner stretchable portion may be the same or different. This configuration prevents the wearer's underwear or skin from showing through the first stretchable portion 70 compared to a single-layer structure, thereby improving the wearer's convenience. Furthermore, using different colors for the rib material of the outer stretchable portion 71 and the inner stretchable portion makes it easier to create designs for the garment 1 that meet the needs of the user, for example.

[0043] The first feature described above allows the first stretchable section 70 to stretch in the vertical direction more than the back body section 10b. The first stretchable section 70 can stretch in response to the movement of the wearer (particularly a wearer engaged in medical work) while wearing the garment. This improves the wearer's mobility while wearing the garment compared to a garment without the first stretchable section 70. Furthermore, since the lower garment includes the first tightening section 40 and the second tightening section at the upper end, and the first stretchable section 70 is located near the upper end of the back body section 10b, even if the upper end of the back body section is pulled downward as the first stretchable section 70 stretches, the first tightening section 40 and the second tightening section prevent the upper end of the back body section 10b from slipping down, thereby maintaining the wearer's mobility while wearing the garment. Furthermore, for example, when the wearer is in a forward-leaning posture while wearing the garment, it is possible to prevent a gap from forming between the upper end portion of the back body 10b and the surrounding area and the wearer, thereby preventing the wearer's underwear or skin from being exposed to the outside through the gap.

[0044] (Configuration - Mobility Improvement Structure - Second Feature) Returning to FIG. 2, the second feature of the mobility enhancing structure is that the garment body 10 is provided with a right second stretchable section 81 and a left second stretchable section 82, as shown in FIGS.

[0045] (Configuration - Mobility-enhancing structure - First feature - Second elastic section on the right side, second elastic section on the left side) The right-side second stretchable section 81 and the left-side second stretchable section 82 are stretchable sections (second stretchable sections) that are stretchable. These right-side second stretchable section 81 and left-side second stretchable section 82 are formed separately from the garment body 10 and the first stretchable section 70, and are made of, for example, a known stretchable material (e.g., woven material, knit material, or ribbed material).

[0046] The right second stretchable portion 81 and the left second stretchable portion 82 are provided in the second crotch cutout 17. Specifically, as shown in FIG. 3, the right second stretchable portion 81 is disposed at the right end of the first stretchable portion 70 in the width direction in the second crotch cutout 17, and the left second stretchable portion 82 is disposed at the left end of the first stretchable portion 70 in the width direction in the second crotch cutout 17 (i.e., they are provided at the end of the first stretchable portion 70 in the width direction in the back body 10b). The right second stretchable portion 81 and the left second stretchable portion 82 are each connected to the crotch portion 11 of the back body 10b and the first stretchable portion 70 via a seam 83 (hereinafter referred to as the "second stretchable portion-side seam 83"). In this embodiment, as shown in FIG. 3, a first stretchable portion 70, a right second stretchable portion 81, and a left second stretchable portion 82 are provided over the entire second crotch side cutout portion 17.

[0047] Furthermore, the specific shapes and sizes of the right side second stretchable portion 81 and the left side second stretchable portion 82 are arbitrary, but in this embodiment they are set as follows. That is, as shown in FIG. 3, the right side second stretchable portion 81 and the left side second stretchable portion 82 are each set to a substantially trapezoidal shape (a trapezoid in which the vertical length of the inner end in the width direction is longer than the vertical length of the outer end in the width direction). The left-right length (width) of each of the right side second stretchable portion 81 and the left side second stretchable portion 82 is set to be shorter than the horizontal length of the first stretchable portion 70 (for example, set to be approximately half the horizontal length of the first stretchable portion 70). The up-down length of the right side second stretchable portion 81 and the left side second stretchable portion 82 is set to be shorter than the vertical length of the crotch portion 11 (for example, set to be equal to or longer than the vertical length of the first stretchable portion 70). With this setting, excessive deformation of the right side second stretchable portion 81 and the left side second stretchable portion 82 can be prevented compared to when the width of each of the right side second stretchable portion 81 and the left side second stretchable portion 82 is the same as the width of the first stretchable portion 70, and the right side second stretchable portion 81 and the left side second stretchable portion 82 can be made to fit the wearer more easily, making it easier to maintain the wearability and design of the garment 1.

[0048] Furthermore, the direction of the grain in each of the right side second stretchable section 81 and the left side second stretchable section 82 is arbitrary, but in this embodiment, the direction of the grain in each of the right side second stretchable section 81 and the left side second stretchable section 82 is set to be inward (or outward) in the width direction as it extends downward (i.e., it is set to be in a direction different from the direction of the grain in the back body 10b). For example, it is preferable to set the angle of the direction of the grain in each of the right side second stretchable section 81 and the left side second stretchable section 82 to be approximately 45 degrees with respect to the width direction so that each of the right side second stretchable section 81 and the left side second stretchable section 82 can easily stretch when the upper portion of the back body 10b is pulled downward or widthwise due to the wearer's movement while wearing the garment as described above. This increases the amount of stretch in the up-down direction of the right side second stretchable section 81 and the left side second stretchable section 82 compared to when the grain direction in each of the right side second stretchable section 81 and the left side second stretchable section 82 is along the up-down direction, making it possible to make the right side second stretchable section 81 and the left side second stretchable section 82 more compact while increasing the stretchability of the right side second stretchable section 81 and the left side second stretchable section 82. However, without being limited to this, for example, the grain direction in each of the right side second stretchable section 81 and the left side second stretchable section 82 may be set to be along the up-down direction.

[0049] Furthermore, the stretch amounts of the right side second stretchable section 81 and the left side second stretchable section 82 are arbitrary, but in this embodiment, the stretch amount of each of the right side second stretchable section 81 and the left side second stretchable section 82 in the vertical direction is set to be smaller than the stretch amount of the first stretchable section 70 (i.e., the stretch amount of the first stretchable section 70 in the vertical direction is set to be larger than the stretch amount of the second stretchable section). Specifically, the stretch amount of each of the right side second stretchable section 81 and the left side second stretchable section 82 in the vertical direction is set to be approximately the same as that of the back body section 10b, but this is not limited to this, and for example, the stretch amount of each of the right side second stretchable section 81 and the left side second stretchable section 82 in the vertical direction can be set to be larger than that of the back body section 10b. This prevents excessive deformation of the right side second stretchable section 81 and the left side second stretchable section 82 compared to when the stretch amount of the first stretchable section 70 in the vertical direction is the same as that of the right side second stretchable section 81 and the left side second stretchable section 82, thereby maintaining the wearability and design of the garment 1. Furthermore, by setting the amount of vertical stretch of each of the right side second stretchable section 81 and the left side second stretchable section 82 to be greater than the amount of vertical stretch of the back body 10b, the elasticity of the right side second stretchable section 81 and the left side second stretchable section 82 can be increased while improving the wearer's ease of movement when worn as described above.

[0050] Furthermore, other specific configurations of the right-side second stretchable section 81 and the left-side second stretchable section 82 are arbitrary, but in this embodiment they are configured as follows.

[0051] First, in order to improve the manufacturability of the garment 1, the right second stretchable section 81 and the left second stretchable section 82 are made of the same material as the back body section 10b. However, this is not a limitation, and they may be made of, for example, different materials.

[0052] As described above, multiple second stretchable section-side seams 83 are provided surrounding the right-side second stretchable section 81 and the left-side second stretchable section 82. Of the multiple second stretchable section-side seams 83, the second stretchable section-side seam 83 (first seam) located at the boundary between the first stretchable section 70 and the right-side second stretchable section 81 (or the left-side second stretchable section 82) is formed to slope downward and outward in the width direction. The inclination angle of this second stretchable section-side seam 83 is arbitrary, but in the embodiment, it is set to about 45 degrees to enable efficient cutting of the first stretchable section 70, right-side second stretchable section 81, and left-side second stretchable section 82 (for example, to increase the yield rate) and to enable effective stretching. However, the angle is not limited to this and may be set to an angle greater or less than 45 degrees. This prevents the right-side second stretchable portion 81 and the left-side second stretchable portion 82 from stretching in conjunction with the stretching of the first stretchable portion 70, preventing the right-side second stretchable portion 81 and the left-side second stretchable portion 82 from stretching excessively. Furthermore, compared to when the second stretchable portion-side seam 83 extends downward and inward in the width direction, this allows the second stretchable portion-side seam 83 to stretch more effectively in response to the wearer's movements while being worn. Furthermore, this prevents a decrease in cutting efficiency of the first stretchable portion 70 or the right-side second stretchable portion 81 and the left-side second stretchable portion 82, and makes it easier to ensure the size of the first stretchable portion 70 required to achieve the desired amount of stretch.

[0053] Furthermore, of the multiple second stretchable portion-side seams 83, the second stretchable portion-side seam 83 (second seam) is provided at the boundary between the right second stretchable portion 81 (or the left second stretchable portion 82) and the back body 10b (specifically, the crotch portion 11). This prevents the right second stretchable portion 81 (or the left second stretchable portion 82) from stretching in conjunction with the stretching of the back body 10b, preventing the right second stretchable portion 81 (or the left second stretchable portion 82) from stretching excessively. Furthermore, sewing the right second stretchable portion 81 and the left second stretchable portion 82 is relatively easy, and the strength (vertical strength) of the right second stretchable portion 81 and the left second stretchable portion 82 can be easily ensured.

[0054] The second feature described above allows the wearer to move more easily when worn as described above, compared to when the garment 1 is provided with only the first stretchable section 70.

[0055] (Configuration - Mobility-enhancing structure - Third feature) Next, regarding the third feature of the mobility-enhancing structure, the first stretchable section 70 is breathable, and specifically, is constructed using a known stretchable material or the like that has breathability equal to or greater than a predetermined standard value. Here, "breathability" refers to the property of allowing air and other gases to pass through. In this embodiment, the "air permeability (amount of air passing through per unit time)," which is an index showing the degree of breathability, is measured using the test method specified in "JIS L 1096 Method A Breathability Test" (unit: cm 3 / cm 2 ·sec). The "predetermined standard value" refers to the minimum amount of ventilation required to cool the wearer, and as an example, the predetermined standard value is 100 cm 3 / cm 2 ·Sec.

[0056] This third feature allows ventilation between the inside and outside of the garment 1 via only the first stretchable section 70, or allows ventilation by drawing air in from below the garment 1 and exhausting it through the first stretchable section 70 (ventilation utilizing the so-called chimney effect), thereby cooling at least the back waist area of ​​the wearer. Here, the "chimney effect" refers to the phenomenon in which, when air hotter than the outside air is present inside a chimney-shaped object, the hot air has a lower density than the cold air and therefore has buoyancy, causing the hot air to rise inside the chimney-shaped object while drawing in cold air from the outside through the opening at the bottom of the chimney-shaped object. That is, in the embodiment, this refers to the effect (phenomenon) in which, when hot air warmed by the wearer is present inside the hollow garment 1, the hot air becomes buoyant, drawing in outside air from below into the garment 1, causing the hot air to rise inside the garment 1.

[0057] (Configuration - Mobility Improvement Structure - 4th Feature) Next, with regard to the fourth feature of the structure for improving ease of movement, the garment body 10 (the front body 10a and the parts of the back body 10b other than the first stretchable section 70, the right side second stretchable section 82, and the left side second stretchable section 83) is formed as a third stretchable section 90, and the amount of vertical stretch of the third stretchable section 90 is set to be smaller than the amount of vertical stretch of the right side second stretchable section 82 (or the left side second stretchable section 83).

[0058] Specifically, it is made of a material that is more stretchable than conventional clothing bodies, and as an example, as described above, it is made of a known woven material, a single-layer knit material, a known multi-layer knit material, or a combination of these.

[0059] Here, the stretch rates of the first elastic section 70, the right-side second elastic section 82, the left-side second elastic section 83, and the third elastic section 90 can be set arbitrarily, but it is desirable to set, for example, the vertical stretch rate of the first elastic section 70 to 100% or more, the vertical stretch rate of the right-side second elastic section 82 (or the left-side second elastic section 83) to about 15%, and the vertical stretch rate of the third elastic section 90 to about 11% (note that these numerical values ​​are based on JIS L 1906 B method).

[0060] The fourth feature described above allows the first elasticated section 70, right second elasticated section 82, left second elasticated section 83, and third elasticated section 90 to enhance the stretchability of the entire garment 1 and make it easier to fit to the wearer's movements. In particular, the garment stretches most at the waist where the first elasticated section 70 is located, and the amount of stretch gradually decreases from the right second elasticated section 82 (or left second elasticated section 83) to the third elasticated section 90, thereby achieving three-dimensional elastic properties in which the amount of stretch gradually changes from the waist to the buttocks of the garment 1, allowing it to effectively fit to the wearer's movements.

[0061] (The effect of clothing) Next, the operation of the garment 1 configured in this manner will be described.

[0062] That is, for example, when a wearer tries to bend forward while wearing the garment, the first stretchable portion 70, the right second stretchable portion 81, and the left second stretchable portion 82 each stretch downward, making it easier for the wearer to bend forward and maintain that bent-over state. In particular, the first stretchable portion 70 is positioned so that the widthwise end of the first stretchable portion 70 and the portion of the back body 10b that corresponds to the top of the wearer's buttocks are positioned widthwise outward of the same straight line. This allows the first stretchable portion 70 to be effectively stretched when the upper portion of the back body 10b is pulled downward by the top of the wearer's buttocks. Furthermore, because the amount of vertical stretch of the first stretchable portion 70 is greater than the amounts of vertical stretch of the first stretchable portion 70, the right second stretchable portion 81, and the left second stretchable portion 82, excessive deformation of the right second stretchable portion 81 and the left second stretchable portion 82 can be suppressed. Therefore, for example, it is possible to avoid constriction of the wearer's areas (such as the waist) corresponding to the right side second stretchable section 81 and left side second stretchable section 82 by the stretched right side second stretchable section 81 and left side second stretchable section 82. Thereafter, when the wearer's posture changes from a bent-over position to an upright position, the first stretchable section 70, right side second stretchable section 81, and left side second stretchable section 82 each contract, thereby returning the first stretchable section 70, right side second stretchable section 81, and left side second stretchable section 82 to their pre-stretched states.

[0063] Furthermore, for example, when the wearer is in an upright position while wearing the garment, ventilation can be achieved between the inside and outside of the garment 1 only through the first stretchable portion 70, or air can be drawn in from below the garment 1 and exhausted through the first stretchable portion 70, thereby cooling at least the back side of the wearer's waist.

[0064] (Test results) Next, the results of the mobility confirmation test for clothing will be described. Here, the "mobility confirmation test" is a test to confirm the ease of movement of a wearer when wearing various types of clothing, which will be described later.

[0065] First, the test subjects for this ease of movement confirmation test will be described. Four types of garments were used as test subjects: garment A, which is garment 1 according to the embodiment (specifically, garment 1 including a substantially rectangular first stretchable portion 70); garment B, which is configured such that the first stretchable portion 70 is formed into a substantially inverted pentagonal shape among the configuration of garment 1 according to the embodiment; garment C, which is configured such that the right second stretchable portion 81, the left second stretchable portion 82, and the third stretchable portion 90 are omitted from the configuration of garment 1 according to the embodiment and the omitted portions are made of a material with little stretch; and garment D, which is configured such that the various stretchable portions are omitted from the configuration of garment 1 according to the embodiment and the omitted portions are made of the same material as the garment body 10.

[0066] The test method for the ease of movement confirmation test was as follows: First, a subject wore one of garments A to D (specifically, the garment was worn by tying the first tightening portion 40), and pressure sensors were attached to the back of the garment in areas corresponding to the subject's buttocks and knees. Then, with the subject leaning forward, the pressure sensors measured the pressure on the buttocks (hereinafter referred to as "buttocks clothing pressure") and the pressure on the knees (hereinafter referred to as "knee clothing pressure").

[0067] Next, the results of this ease of movement confirmation test will be explained. Figure 5 shows the test results of the ease of movement confirmation test. Below, the test results for garments A to D will be explained. However, for garment C, clothing pressure at the buttocks was not measured, so only the results for clothing pressure at the knees will be explained, and for garment D, clothing pressure at the buttocks will be explained, so only the results for clothing pressure at the knees will be explained.

[0068] As shown in Figure 5, the clothing pressure results for the buttocks were: Clothing A = 1.19 kPa, Clothing B = 1.26 kPa, Clothing D = 1.48 kPa, which means that Clothing A and Clothing B were approximately 15% lower than Clothing D. These results confirm that Clothing A and Clothing B can reduce the load on the wearer's buttocks compared to Clothing D, and therefore Clothing A and Clothing B can improve the wearer's ease of movement.

[0069] Furthermore, as shown in Figure 5, the clothing pressure results for the knee area were: Clothing A = 1.55 kPa, Clothing B = 1.70 kPa, Clothing C = 2.59 Pka, which means that Clothing A and Clothing B were approximately 34% lower than Clothing C. These results confirm that Clothing A and Clothing B can reduce the load on the wearer's knee area compared to Clothing C, and therefore Clothing A and Clothing B can improve the wearer's ease of movement.

[0070] As described above, the test results shown in Fig. 5 confirm the effectiveness of providing garments with the first stretchable portion 70, right side second stretchable portion 81, left side second stretchable portion 82, and third stretchable portion 90, as garments A and B provide improved ease of wearer movement compared to garment D. Furthermore, because garments A and B provide improved ease of wearer movement compared to garment C, the effectiveness of providing garments with the right side second stretchable portion 81, left side second stretchable portion 82, and third stretchable portion 90 was also confirmed.

[0071] (Effects of the embodiment) As described above, according to this embodiment, the garment is provided with the first stretchable section 70 at the upper end of the back body 10b or in the vicinity thereof, and the amount of stretch of the first stretchable section 70 in the vertical direction is greater than the amount of stretch of the back body 10b in the vertical direction, so that the first stretchable section 70 can stretch in accordance with the movement of the wearer (particularly a wearer engaged in medical work) while wearing the garment. Therefore, the wearer's ease of movement while wearing the garment can be improved compared to when the first stretchable section 70 is not provided.

[0072] In addition, the back body 10b is provided with a right side second stretchable section 81 (or left side second stretchable section 82) provided at the widthwise end of the first stretchable section 70, and the amount of vertical stretch of the first stretchable section 70 is greater than the amount of vertical stretch of the right side second stretchable section 81 (or left side second stretchable section 82).This means that excessive deformation of the right side second stretchable section 81 (or left side second stretchable section 82) can be prevented compared to when the amount of vertical stretch of the first stretchable section 70 and the amount of vertical stretch of the right side second stretchable section 81 (or left side second stretchable section 82) are the same, thereby maintaining the wearability and design of the garment 1.

[0073] Furthermore, the first stretchable portion 70 is formed so that the width of the first stretchable portion 70 is shorter than the width of the back body 10b, and the right second stretchable portion 81 (or the left second stretchable portion 82) is formed so that the width of the right second stretchable portion 81 (or the left second stretchable portion 82) is shorter than the width of the first stretchable portion 70. Therefore, compared to when the width of the right second stretchable portion 81 (or the left second stretchable portion 82) is the same as the width of the first stretchable portion 70, excessive deformation of the right second stretchable portion 81 (or the left second stretchable portion 82) can be suppressed, and the right second stretchable portion 81 (or the left second stretchable portion 82) can be made to fit the wearer more easily, making it easier to maintain the wearability and design of the garment 1.

[0074] Furthermore, the amount of vertical stretch of the right side second stretchable section 81 (or the left side second stretchable section 82) is greater than the amount of vertical stretch of the back body 10b, thereby improving the wearer's ease of movement when worn as described above while increasing the stretchability of the right side second stretchable section 81 (or the left side second stretchable section 82).

[0075] Furthermore, the back body 10b is formed so that the grain of the back body 10b runs roughly along the vertical direction, and the right side second stretchable section 81 (or the left side second stretchable section 82) is formed so that the grain of the right side second stretchable section 81 (or the left side second stretchable section 82) runs outward or inward in the width direction as it goes downward.This means that the amount of vertical stretch of the right side second stretchable section 81 (or the left side second stretchable section 82) can be increased compared to when the grain of the right side second stretchable section 81 (or the left side second stretchable section 82) runs along the vertical direction, and it is possible to make the right side second stretchable section 81 (or the left side second stretchable section 82) more compact while increasing the stretchability of the right side second stretchable section 81 (or the left side second stretchable section 82).

[0076] Furthermore, the first stretchable section 70 and the right-side second stretchable section 81 (or the left-side second stretchable section 82) are formed separately, and a first seam is provided at the boundary between the first stretchable section 70 and the right-side second stretchable section 81 (or the left-side second stretchable section 82). The first seam is formed so that the first seam extends downward and outward in the width direction. This prevents the right-side second stretchable section 81 (or the left-side second stretchable section 82) from stretching as the first stretchable section 70 extends, preventing the right-side second stretchable section 81 (or the left-side second stretchable section 82) from stretching excessively. Furthermore, compared to when the first seam extends downward and inward in the width direction, the first stretchable section 70 can stretch and contract more effectively in response to the wearer's movements when worn as described above. Furthermore, it is easier to ensure the size of the first stretchable section 70 required to obtain the desired amount of stretch, while preventing a decrease in the efficiency of cutting the first stretchable section 70 or the right-side second stretchable section 81 (or the left-side second stretchable section 82).

[0077] Furthermore, the right side second stretchable section 81 (or the left side second stretchable section 82) and the back body 10b are formed separately, and a second seam is provided at the boundary between the right side second stretchable section 81 (or the left side second stretchable section 82) and the back body 10b. This prevents the right side second stretchable section 81 (or the left side second stretchable section 82) from stretching in conjunction with the stretching of the back body 10b, and prevents the right side second stretchable section 81 (or the left side second stretchable section 82) from stretching too much. Furthermore, sewing the right side second stretchable section 81 (or the left side second stretchable section 82) is relatively easy, and it is easier to ensure the strength (vertical strength) of the right side second stretchable section 81 (or the left side second stretchable section 82).

[0078] Furthermore, the front body 10a and the back body 10b portions other than the first elasticized portion 70, right second elasticized portion 82, and left second elasticized portion 83 are formed as the third elasticized portion 90, and the amount of vertical stretch of the third elasticized portion 90 is smaller than the amount of vertical stretch of the right second elasticized portion 82 (or left second elasticized portion 83). This allows the first elasticized portion 70, right second elasticized portion 82, left second elasticized portion 83, and third elasticized portion 90 to enhance the stretchability of the entire garment 1 and make it easier to fit to the wearer's movements. In particular, the garment 1 is most stretchable at the waist where the first elasticized portion 70 is located, and the amount of stretch gradually decreases from the right second elasticized portion 82 (or left second elasticized portion 83) to the third elasticized portion 90. This provides three-dimensional elastic properties in which the amount of stretch gradually changes from the waist to the buttocks of the garment 1, allowing it to effectively fit to the wearer's movements.

[0079] Furthermore, the first stretchable section 70 is positioned so that the widthwise end of the first stretchable section 70 and the portion of the back body 10b corresponding to the top of the wearer's buttocks are positioned approximately on the same line or widthwise outward from that line.Therefore, when the upper portion of the back body 10b is pulled downward by the top of the wearer's buttocks, the first stretchable section 70 can be effectively stretched, making it even easier to improve the wearer's ease of movement when worn as described above, compared to when the widthwise end of the first stretchable section 70 and the portion of the back body 10b corresponding to the top of the wearer's buttocks are positioned widthwise inward from that line.

[0080] Furthermore, since the first stretchable portion 70 is formed in a substantially rectangular shape that is generally aligned with the width direction, the first stretchable portion 70 is easier to form than if it were formed in a curved shape, thereby improving the manufacturability of the garment 1.

[0081] Furthermore, the first stretchable section 70 is breathable and allows air in the back body 10b to be exhausted through the first stretchable section 70 for ventilation, so that ventilation can be achieved between the inside and outside of the garment 1 solely through the first stretchable section 70, or air drawn in from below the garment 1 can be exhausted through the first stretchable section 70 for ventilation (ventilation can be achieved by utilizing the so-called chimney effect), making it possible to cool at least the back side of the waist of the wearer.

[0082] Furthermore, the garment 1 includes a first tightening section 40 and a second tightening section provided at the upper end thereof for tightening the garment 1 around the wearer, and the first stretchable section 70 is provided near the upper end of the back body section 10b. Therefore, even if the upper end of the back body section 10b is pulled downward as the first stretchable section 70 extends, the first tightening section 40 and the second tightening section prevent the upper end of the back body section 10b from slipping down, thereby maintaining the wearer's ease of movement when worn as described above. Furthermore, for example, when the wearer is leaning forward while wearing the garment as described above, it is possible to prevent a gap from forming between the upper end of the back body section 10b and its vicinity and the wearer, thereby preventing the wearer's underwear or skin from being exposed to the outside through the gap.

[0083] [III] Modifications to the embodiment Although the embodiments of the present invention have been described above, the specific configurations and means of the present invention can be modified and improved as desired within the scope of the technical ideas of the inventions set forth in the claims. Such modifications will be described below.

[0084] (About the problem to be solved and the effects of the invention) First, the problems that the invention aims to solve and the effects of the invention are not limited to those described above, and may vary depending on the implementation environment of the invention and the details of the configuration, and may solve only some of the problems described above or achieve only some of the effects described above.

[0085] (shape, numbers, structure, time series) The components illustrated in the above embodiments and drawings may be modified or improved as desired within the scope of the technical concept of the present invention in terms of their shapes, values, structures, or chronological relationships. For example, unless otherwise specified, each part of the garment body 10 may be manufactured in a shape, method, or material different from those described above.

[0086] (About clothing) In the above embodiment, the garment 1 is described as including a first crotch-side opening / closing section, a second crotch-side opening / closing section 30, a first tightening section 40, a second tightening section, a gusset section 50, a right pocket section 61, and a left pocket section 62. However, this is not limiting. For example, at least one of the first crotch-side opening / closing section, the second crotch-side opening / closing section 30, the first tightening section 40, the second tightening section, the gusset section 50, the right pocket section 61, and the left pocket section 62 may be omitted. Here, when the first tightening section 40 and the second tightening section are omitted, for example, belt loops may be provided at the upper ends of the front body section 10a and the back body section 10b so that the garment 1 can be tightened around the wearer with a belt threaded through the belt loops. Furthermore, when the first crotch-side opening / closing section and the second crotch-side opening / closing section 30 are omitted, the first crotch-side cutout section 16 and the extension section may be omitted. Furthermore, when the gusset portion 50 is omitted, the crotch-side cutout portion 18 may be omitted.

[0087] (About the clothing itself) In the above embodiment, it has been described that a first stretchable section 70-side seam and a second stretchable section 83-side seam are provided, but this is not limiting, and for example, at least one of the first stretchable section 70-side seam or the second stretchable section 83-side seam may be omitted. In this case, for example, if the first stretchable section 70-side seam is omitted, the first stretchable section 70 and the back body 10b may be simply fixed together by sewing or the like (the same applies to the case where the second stretchable section 83 is omitted).

[0088] (Regarding the first expansion section) In the above embodiment, it was described that the first stretchable portion 70 is made of a stretchable material having a breathability equal to or greater than a predetermined standard value, but this is not limited to this, and it may be made of a stretchable material having a breathability less than the predetermined standard value, for example.

[0089] In the above embodiment, the first stretchable portion 70 is described as being made of a stretchable and breathable rib material, mesh material, or a combination thereof, but is not limited to this. For example, instead of these materials, the first stretchable portion 70 may be made of a stretchable woven material or multi-layer knit material with multiple ventilation holes (the same applies to the gusset portion 50).

[0090] Furthermore, in the above embodiment, the first stretchable section 70 is described as having a double structure (a structure having an outer stretchable section 71 and an inner stretchable section), but this is not limited to this and may be, for example, a single structure.

[0091] In the above embodiment, the first stretchable section 70 is described as being arranged so that the widthwise end of the first stretchable section 70 and the portion of the back body 10b that corresponds to the top of the wearer's knees or the top of the buttocks are positioned on approximately the same straight line, but this is not limited to this. For example, the widthwise end of the first stretchable section 70 and the portion of the back body 10b that corresponds to the top of the wearer's knees or the top of the buttocks may be positioned on a non-collinear line.

[0092] In the above embodiment, the first stretchable portion 70 is formed in a generally rectangular shape extending generally along the width direction, but this is not limiting. For example, from the perspective of improving the manufacturability of the first stretchable portion 70, it may be formed in an inverted pentagonal shape, as in garment B shown in the above test results.

[0093] (Regarding the second expansion section) In the above embodiment, it was explained that the garment 1 is provided with a right side second stretchable portion 81 and a left side second stretchable portion 82, but this is not limited to this, and at least one of the right side second stretchable portion 81 or the left side second stretchable portion 82 may be omitted.

[0094] Furthermore, in the above embodiment, it was explained that the width of each of the right-side second stretchable section 81 and the left-side second stretchable section 82 is set to be shorter than the width of the first stretchable section 70, but this is not limited to this, and for example, they may be set to be the same or longer.

[0095] Furthermore, in the above embodiment, the second elastic section is described as having elasticity, but this is not limited thereto. For example, in addition to elasticity, the second elastic section may have breathability similar to that of the first elastic section 70.

[0096] (Addendum) The garment of Appendix 1 is a garment worn by a wearer, and comprises at least an undergarment having a front body and a back body, and comprises a first stretchable portion provided at the upper end of the back body or a portion nearby, and the amount of stretch in the vertical direction of the first stretchable portion is greater than the amount of stretch in the vertical direction of the back body.

[0097] The garment of Appendix 2 is the garment described in Appendix 1, which has a second stretchable section provided at the widthwise end of the first stretchable section in the back body portion, and the amount of vertical stretch of the first stretchable section is greater than the amount of vertical stretch of the second stretchable section.

[0098] The garment of Appendix 3 is the garment described in Appendix 2, wherein the first stretchable portion is formed so that the width of the first stretchable portion is shorter than the width of the back body, and the second stretchable portion is formed so that the width of the second stretchable portion is shorter than the width of the first stretchable portion.

[0099] The garment of Supplementary Note 4 is the garment of Supplementary Note 2 or 3, wherein the amount of stretch in the vertical direction of the second stretchable section is greater than the amount of stretch in the vertical direction of the back body.

[0100] The garment of Appendix 5 is a garment described in any one of Appendixes 2 to 4, wherein the back body is formed so that the grain direction of the back body is roughly along the vertical direction, and the second stretchable portion is formed so that the grain direction of the second stretchable portion moves outward or inward in the width direction as it moves downward.

[0101] The garment of Appendix 6 is the garment described in any one of Appendixes 2 to 5, in which the first stretchable portion and the second stretchable portion are formed separately, a first seam portion is provided at the boundary between the first stretchable portion and the second stretchable portion, and the first seam portion is formed so that it extends downward and outward in the width direction.

[0102] The garment of Appendix 7 is a garment described in any one of Appendixes 2 to 6, in which the second stretchable portion and the back body are formed separately, and a second seam portion is provided at the boundary between the second stretchable portion and the back body.

[0103] The garment of Appendix 8 is the garment of any one of Appendixes 2 to 7, wherein the front body and the portion of the back body other than the first stretchable portion and the second stretchable portion are formed as a third stretchable portion, and the amount of vertical stretch of the third stretchable portion is smaller than the amount of vertical stretch of the second stretchable portion.

[0104] The garment of Appendix 9 is a garment described in any one of Appendixes 1 to 8, wherein the first stretchable portion is positioned so that the widthwise end of the first stretchable portion and the portion of the back body corresponding to the top of the wearer's buttocks are positioned on approximately the same straight line or widthwise outward of that same straight line.

[0105] The garment of Supplementary Note 10 is the garment of any one of Supplementary Notes 1 to 9, wherein the first stretchable portion is formed in a substantially rectangular shape that extends substantially along the width direction.

[0106] The garment of Appendix 11 is the garment described in any one of Appendixes 1 to 10, wherein the first stretchable portion is breathable and allows air in the rear body portion to be exhausted through the first stretchable portion for ventilation.

[0107] The garment of Appendix 12 is a garment described in any one of Appendixes 1 to 11, which has a tightening portion provided at the upper end of the lower garment for tightening the garment around the wearer, and the first stretchable portion is provided in the vicinity of the upper end of the back body.

[0108] (Effect of supplementary notes) The garment described in Appendix 1 includes a first stretchable section provided at or near the upper end of the back body, and the amount of vertical stretch of the first stretchable section is greater than the amount of vertical stretch of the back body, so that the first stretchable section can stretch in accordance with the movement of the wearer (particularly a wearer engaged in medical work) while wearing the garment. This improves the ease of movement of the wearer while wearing the garment, compared to a garment without the first stretchable section.

[0109] The garment described in Appendix 2 includes a second stretchable section provided at the widthwise end of the first stretchable section in the back body portion, and the amount of vertical stretch of the first stretchable section is greater than the amount of vertical stretch of the second stretchable section. This prevents the second stretchable section from deforming excessively compared to when the amounts of vertical stretch of the first stretchable section and the second stretchable section are the same, thereby maintaining the wearability and design of the garment.

[0110] According to the garment described in Appendix 3, the first stretchable portion is formed so that the width of the first stretchable portion is shorter than the width of the back body, and the second stretchable portion is formed so that the width of the second stretchable portion is shorter than the width of the first stretchable portion.This prevents the second stretchable portion from deforming excessively compared to when the widths of the second stretchable portion and the first stretchable portion are the same, and makes it easier to fit the second stretchable portion to the wearer, making it easier to maintain the wearability and design of the garment.

[0111] According to the garment described in Appendix 4, the amount of vertical stretch of the second stretchable section is greater than the amount of vertical stretch of the back body, thereby improving the wearer's ease of movement when worn as described above while increasing the elasticity of the second stretchable section.

[0112] According to the garment described in Appendix 5, the back body is formed so that the grain of the back body runs roughly along the vertical direction, and the second stretchable portion is formed so that the grain of the second stretchable portion runs outward or inward in the width direction as it goes downward.This means that the amount of vertical stretch of the second stretchable portion can be increased compared to when the grain of the second stretchable portion runs along the vertical direction, and it is possible to make the second stretchable portion more compact while increasing its stretchability.

[0113] According to the garment described in Appendix 6, the first stretchable section and the second stretchable section are formed separately, and a first seam is provided at the boundary between the first stretchable section and the second stretchable section. The first seam is formed so that the first seam extends outward in the width direction as it extends downward. This prevents the second stretchable section from stretching in conjunction with the extension of the first stretchable section, preventing excessive stretching of the second stretchable section. Furthermore, compared to a case where the first seam extends inward in the width direction as it extends downward, the first stretchable section can be stretched more effectively in response to the wearer's movements while being worn. Furthermore, it is easier to ensure the size of the first stretchable section required to achieve the desired amount of stretch while preventing a decrease in cutting efficiency of the first stretchable section or the second stretchable section.

[0114] According to the garment described in Appendix 7, the second stretchable section and the back body are formed separately, and a second seam is provided at the boundary between the second stretchable section and the back body, which prevents the second stretchable section from stretching in conjunction with the stretching of the back body and prevents the second stretchable section from stretching too much. Furthermore, sewing the second stretchable section is relatively easy, and it is easy to ensure the strength (vertical strength) of the second stretchable section.

[0115] According to the garment described in Appendix 8, the front body and the portions of the back body other than the first and second elasticized sections are formed as a third elasticized section, and the amount of vertical stretch of the third elasticized section is smaller than that of the second elasticized section, so the first, second, and third elasticized sections increase the stretchability of the entire garment and make it easier to fit the wearer's movements. In particular, the waist section, where the first elasticized section is located, is the most stretchable, and the amount of stretch gradually decreases from the second elasticized section to the third elasticized section, thereby achieving three-dimensional elastic properties in which the amount of stretch gradually changes from the waist section to the buttocks of the garment, allowing it to effectively fit the wearer's movements.

[0116] According to the garment described in Appendix 9, the first stretchable portion is positioned so that the widthwise end of the first stretchable portion and the portion of the back body corresponding to the top of the wearer's buttocks are approximately on the same line or are located widthwise outward of that line.Therefore, when the upper portion of the back body is pulled downward by the top of the wearer's buttocks, the first stretchable portion can be stretched effectively, compared to when the widthwise end of the first stretchable portion and the portion of the back body corresponding to the top of the wearer's buttocks are located widthwise inward of that line, which makes it easier to further improve the wearer's ease of movement when worn as described above.

[0117] According to the garment described in Appendix 10, the first stretchable portion is formed in a generally rectangular shape that is generally aligned with the width direction, or in a generally inverted pentagonal shape. This makes it relatively easy to form the first stretchable portion, thereby improving the manufacturability of the garment.

[0118] According to the garment described in Appendix 11, the first stretchable portion is breathable and allows air in the back portion to be exhausted through the first stretchable portion for ventilation, so that ventilation can be achieved between the inside and outside of the garment via only the first stretchable portion, or air drawn in from below the garment can be exhausted through the first stretchable portion for ventilation (ventilation can be achieved by utilizing the so-called chimney effect), making it possible to cool at least the back waist portion of the wearer.

[0119] According to the garment described in Appendix 12, the garment includes a tightening section provided at the upper end of the lower garment for tightening the garment around the wearer, and the first stretchable section is provided in the vicinity of the upper end of the back body, so that even if the upper end of the back body is pulled downward as the first stretchable section stretches, the tightening section prevents the upper end of the back body from slipping down, while maintaining the wearer's ease of movement when worn. Furthermore, for example, when the wearer is leaning forward while wearing the garment, it is possible to prevent a gap from forming between the upper end of the back body and the vicinity thereof and the wearer, thereby preventing the wearer's underwear or skin from being exposed to the outside through the gap.
