Description

[Technical Field]

[0001] The present invention relates to lower-body garments such as boxer shorts (including short-type boxer shorts (boxer shorts) and long-type boxer shorts (boxer shorts) that reach above the knees, like a woman's girdle) that are lower-body underwear that cover the abdomen and buttocks, and that are comfortable to wear and easily follow the movement of the lower body. Note that the lower-body garments of the present invention are not limited to those for men (referred to as boxer shorts in this specification) and women (referred to as boxer shorts in this specification), and may be lower-body garments that cover at least the abdomen and buttocks. If they have legs, the length may be above the knees, and there is no particular limit to the length. Furthermore, they may be worn as underwear or for sports, and there is no limit to their use. Note that the abdomen primarily refers to the lower abdomen. Furthermore, in the description of the present invention, the terms knitted fabric and fabric are used without limitation (the term fabric refers to a knitted fabric with elasticity, not a woven fabric with (almost) no elasticity). [Background technology]

[0002] There are known lower-body garments that use fabrics with high elasticity (stretches well and shrinks well) and / or fabrics with high compression strength (tightly stretches and fits closely to the body). Knitted fabrics are particularly preferred for this purpose due to their elasticity. One example of such lower-body garments is underwear. Underwear ensures a good fit with uniform pressure distribution, does not feel tight or loose during body movement, and improves the appearance of the garment when worn.

[0003] Boxer shorts, one type of underwear, are made by sewing together fabric pieces for the body, gusset, and placket, which are cut along a flat standard pattern. These fabric pieces are often made of weft-knitted fabrics such as rib knitting, which are stretchable so as not to hinder movement during the various activities of daily life.

[0004] However, even if pieces of fabric cut along a flat pattern that resembles a projection of the body onto a plane are sewn together to create a three-dimensional shape, it is extremely difficult to accommodate the complex three-dimensional curves of a person's abdomen, buttocks, and legs.If the pattern is made larger to avoid uncomfortable pressure, the garment will become loose and the legs will be pulled up toward the buttocks, making it uncomfortable to wear and also unsightly.

[0005] Therefore, the applicant of the present application developed underwear that solves this problem, and this underwear is disclosed in Japanese Patent No. 6672355 (Patent Document 1). The lower-body garment disclosed in Patent Document 1 is a lower-body garment using a knitted fabric having different stretchability in a first direction and a second direction generally perpendicular to the first direction, wherein the stretchability in the first direction is greater than the stretchability in the second direction, the first direction stretches and shrinks more than the second direction, and when the lower-body garment is placed on a plane with a waistline generally horizontal and viewed from the ventral side, the first direction is diagonal at the intersections between the left and right lines of the lower-body garment placed on the plane and the waistline, and when the lower-body garment placed on a plane with the waistline generally horizontal and viewed from the back, the first direction is generally perpendicular to the waistline at the midpoint of the left and right directions of the waistline of the lower-body garment placed on the plane.

[0006] Furthermore, Japanese Patent No. 5128891 (Patent Document 2) discloses a men's lower body garment that has the function of preventing riding up and can provide a fit according to the characteristics of each part of the lower body, making it comfortable to wear. The men's lower body garment disclosed in Patent Document 2 is formed by using two-way stretch fabric with different stretchability in orthogonal directions, and by sewing together sections cut in different stretch directions, and the left and right side fabrics that form the hem edges around the left and right legs at the bottom have greater stretchability in the vertical direction than in the horizontal direction, and these left and right side fabrics are double-layered fabrics that are folded back at the bottom edges that become the hem edges, and the hem edges are not sewn together, but the two layers consisting of an outer part and a skin-side part are sewn together at the waist. Let's say. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] Patent No. 6672355 [Patent Document 2] Patent No. 5128891 Summary of the Invention [Problem to be solved by the invention]

[0008] The lower-body garment disclosed in Patent Document 1 mentioned above is highly desirable and has been well-received for its ease of movement with the lower body and its comfortable fit. However, it suffers from a minor problem in that the fabric orientation is restricted during manufacturing. On the other hand, the men's lower-body garment disclosed in Patent Document 2 employs a structure in which the left and right side fabrics are double-layered fabrics folded back at the bottom, which become the hem edges, and the hem edges are not sewn together, but the two layers, consisting of an outer layer and a skin-side layer, are sewn together at the waist. This structure results in significant problems, such as poor wearing comfort and high manufacturing costs.

[0009] The present invention was developed in consideration of the above-mentioned problems of the prior art (particularly the problems of Patent Document 2), and its purpose is to provide lower body clothing that primarily covers the abdomen and buttocks, and that easily follows the movement of the lower body and is comfortable to wear. [Means for solving the problem]

[0010] In order to achieve the above object, the lower body garment according to the present invention employs the following technical measures.

[0011] In other words, the lower body garment of the first aspect of the present invention is a lower body garment in which the edges of two or more flat stretchable knitted fabrics cut according to a pattern are joined together, and when the joining is released and one of the two or more stretchable knitted fabrics that forms the hem and waistline that covers the thighs is placed on a flat surface so that the waistline is approximately horizontal, the tangent to the hem apex, which is the lower end point of the hem, is at an angle of 35 degrees or more and 55 degrees or less to a vertical line.

[0012] In addition, a lower body garment according to a second aspect of the present invention is a lower body garment in which the edges of two or more stretchable knitted fabrics, including a thick knitted fabric that forms a thick portion that covers the perineum, are joined together in a flat state cut according to a pattern, and when the joining is released and one of the two or more stretchable knitted fabrics that forms the hem and waistline that covers the thighs is placed on a flat surface so that the waistline is approximately horizontal, the straight line of the hem side that joins with the thick knitted fabric is at an angle of 35 degrees to 55 degrees relative to the vertical.

[0013] In both the lower body garments according to the first aspect and the lower body garments according to the second aspect, when the joints are opened, the stretchable knitted fabric and its pattern have approximately the same shape (described as approximately in consideration of the stretchability of the knitted fabric), and the configurations (limitations on the angle range) of the lower body garments according to the first aspect and the lower body garments according to the second aspect can be specified using either the stretchable knitted fabric itself or its pattern, so the expressions are approximately the same whether they are expressed using the stretchable knitted fabric itself or the pattern of the stretchable knitted fabric that forms the hem that covers the thighs (described as approximately in consideration of the stretchability of the knitted fabric).

[0014] By providing such a configuration (limiting the angle range in the lower-body garment according to the first aspect of the present invention or the lower-body garment according to the second aspect of the present invention) (existing products are often in the range of 0 to 30 degrees and are 20 degrees or less), and setting the angle to 35 degrees or more, the amount of fabric in the lower buttocks (gluteal crease) increases when joined (formed into the product shape), allowing for a three-dimensional shape (compared to existing products). For example, for the same waist circumference, the hip circumference at the larger angle will be longer, making it easier to follow the movements of the wearer's lower body (for example, moving the hip joint, bowing, moving from a standing position to a sitting position, and vice versa).

[0015] More preferably, when a wearer wearing the lower-body garment leans forward at 45 degrees, no wrinkles are generated in the lower-body garment at a position corresponding to the buttocks of the wearer, and when the wearer stands upright, wrinkles are generated in the lower-body garment at a position corresponding to the buttocks of the wearer. It can be configured so that

[0016] Thus, when a lower-body garment having the above-described configuration (the limited angle range in the lower-body garment according to the first aspect of the present invention or the lower-body garment according to the second aspect of the present invention) is worn and the wearer assumes a 45-degree forward lean, wrinkles do not form in the position corresponding to the wearer's buttocks (there is not enough slack in the fabric to accommodate subsequent movements, but subsequent movements in which the fabric of the lower-body garment around the buttocks is further pulled from this position are not usually considered), and wrinkles that do form when the wearer assumes an upright position mean that there is more slack in the fabric, making it easier to accommodate movements of the wearer's lower body (for example, moving the hip joints, bowing, moving from a standing position to a sitting position, and vice versa). On the other hand, because humans do not always maintain an upright posture in their daily lives (in fact, they spend significantly more time in positions that are not upright), the occurrence of wrinkles when the wearer is in an upright position is unlikely to be a major problem.

[0017] More preferably, the stretchable knit fabric that forms the hem that covers the thighs can be configured to include a body knit fabric that covers the perineum and at least the buttocks, or to include a body knit fabric that covers at least the buttocks and a thick knit fabric that forms a thick portion that covers the perineum.

[0018] More preferably, the stretchable knit fabric forming the lower-body garment can be configured to include a placket fabric covering the central abdominal portion. In the embodiment described below, this placket fabric includes a front body knit fabric 300FF of the boxer shorts 300 in addition to a placket fabric 100F of the boxer shorts 100 and a placket fabric 200F of the boxer shorts 200. [Effects of the Invention]

[0019] According to the present invention, it is possible to provide lower body clothing that easily follows the movement of the lower body and is comfortable to wear. [Brief explanation of the drawings]

[0021] Hereinafter, as an embodiment of the present invention, boxer shorts (short type mainly for men, but not limited to) and boxer shorts (short type mainly for women, but not limited to) as examples of lower body clothing (including long type that reaches above the knee) will be described in detail with reference to the drawings. Note that the lower body clothing according to the present invention is not limited to boxer shorts and boxer shorts, but may be any lower body clothing that mainly covers the abdomen and buttocks, and may further cover the legs. If the garment has legs, the length of the garment covering the legs is not limited and includes up to the knee, and furthermore, the garment can be worn as underwear or for sports, and its use is not limited, and as mentioned above, it is not limited to either men's or women's.

[0022] 1 to 3 are diagrams showing boxer shorts 100 according to a first embodiment of the present invention, FIGS. 4 to 6 are diagrams showing boxer shorts 200 according to a second embodiment of the present invention, and FIGS. 7 to 9 are diagrams showing boxer shorts 300 according to a third embodiment of the present invention. Also, FIGS. 1, 4, and 7 correspond to FIGS. 2, 5, and 8, and FIGS. 3, 6, and 9, respectively (note that FIG. 10 is a comparative example). FIGS. 1, 4, and 7 show (A) a front view and (B) a back view of the boxer shorts or boxer shorts according to the present embodiment placed on a flat surface (ideal or virtual). FIGS. 2, 5, and 8 are plan views showing a pattern for the boxer shorts or boxer shorts according to the present embodiment. FIGS. 3, 6, and 9 are plan views showing the body fabric B or the pattern for explaining the technical features (of the present invention) of the boxer shorts or boxer shorts according to the present embodiment. The (ideal or virtual) state of being placed on a flat surface means that, for example, these figures are not symmetrical, the three-dimensional shape of the bulging portion of the boxer shorts is not shown, etc. The boxer shorts or boxer shorts according to the embodiment of the present invention are made of a stretchable fabric, and if they are not illustrated in this way, they will be partially shrunk or partially stretched, making it difficult to understand their shape, so they are assumed as described above.

[0023] In addition, in any of the boxer shorts 100 in the first embodiment, the boxer shorts 200 in the second embodiment, and the boxer shorts 300 in the third embodiment, when the joints are opened, the stretchable knitted fabric and its pattern have approximately the same shape (described as approximately in consideration of the stretchability of the knitted fabric), and the limitation of the angle range of the stretchable knitted fabric that forms the hem that covers the thighs, which is a technical feature of the present invention described below, can be specified using either the stretchable knitted fabric itself or its pattern, so the expression is approximately the same whether using the stretchable knitted fabric itself or the pattern of the stretchable knitted fabric that forms the hem that covers the thighs (described as approximately in consideration of the stretchability of the knitted fabric).

[0024] Here, the symbols will be explained. The body knitted fabric B (having a back body covering at least the buttocks) is the body knitted fabric 100B in the boxer shorts 100, the body knitted fabric 200B in the boxer shorts 200, and the body knitted fabric 300B in the boxer shorts 300 (basically, they have at least a back body covering the buttocks and form the hemline, so they may be represented by the body knitted fabric B). The placket knitted fabric F (covering the central abdominal part and forming the bulge (placket part)) is the placket knitted fabric 100F in the boxer shorts 100, and the placket knitted fabric 200B in the boxer shorts 200. 200F, but in boxer shorts 300 it is front body knit fabric 300FF which corresponds to the placket knit fabric (covers the central abdominal part in a flat manner) (basically it is common in that it covers the central abdominal part, so it may be represented by placket knit fabric F or front body knit fabric FF), and the thick knit fabric TH which forms the thick part (crotch part) which covers the perineum is thick knit fabric 200TH in boxer shorts 200 and thick knit fabric 300TH in boxer shorts 300 (basically it is common in that it covers the perineum, so it may be represented by thick knit fabric TH).

[0025] The boxer shorts 100 differ from other common boxer shorts in that they have a waistband WB such as an elastic band around the waist, a bulge (front placket) formed by a placket fabric F, and side portions formed by side knit fabric S on both sides of the bulge (front placket). The boxer shorts 200 differ from the boxer shorts 100 in that they do not have a waistband WB around the waist, and instead of the side portions formed by the side knit fabric S, they have a thick portion formed by a thick knit fabric TH that covers the perineum. The boxer shorts 300 differ from the boxer shorts 200 in that, instead of a bulge (front placket) formed by a placket fabric F, they have a flat front body portion formed by a front body knit fabric FF (corresponding to the placket fabric) that forms a front body that covers the central abdominal region, and an inner thick knit fabric IN that is provided closer to the skin than the thick knit fabric TH, although it is not directly related to the present invention. In this way, the rubber band WB, the side knit fabric S, the placket knit fabric F (which forms a three-dimensional shape), the front body knit fabric FF (which forms a flat shape), and the thick knit fabric TH (including the inner thick knit fabric IN) are of any configuration.

[0026] To facilitate understanding of the technical features of the boxer shorts according to the present invention, Fig. 10 shows the body fabric B (body fabric 400B) of conventional boxer shorts 400, which corresponds to the body fabric B (which is substantially the same shape as the pattern for the body fabric) shown in Fig. 3, Fig. 6 and Fig. 9. The conventional boxer shorts 400 shown in Fig. 10 include a thick knit fabric TH (thick knit fabric 400TH) in addition to the body fabric B (body fabric 400B), but do not include the optional elastic band WB, side knit fabric S, front placket knit fabric F and front body knit fabric FF.

[0027] These boxer shorts 100, boxer shorts 200, and boxer shorts 300 are lower-body garments in which two or more flat stretchable knitted fabrics (which may include a thick knitted fabric TH that forms a thick portion covering the perineum) are cut according to a paper pattern and have their edges joined together. While not limited to these, the boxer shorts 100 are made of five stretchable knitted fabrics (excluding the waistband WB) as shown in Fig. 2, the boxer shorts 200 are made of three stretchable knitted fabrics as shown in Fig. 5, and the boxer shorts 300 are made of four stretchable knitted fabrics as shown in Fig. 8. Here, the number of stretchable knitted fabrics will differ, for example, if the bulge and thick portion are not double-layered. Therefore, the paper patterns shown in these figures are merely examples, and the shape of the paper pattern and the number of stretchable knitted fabrics are merely illustrative, except for the technical features described below.

[0028] The joining may be performed by any of the following methods: sewing the overlapping portions of the knitted fabric edges (synonymous with the edges of the fabric) together with a sewing thread; bonding the overlapping portions of the knitted fabric edges together with an adhesive; bonding the overlapping portions of the knitted fabric edges together with an adhesive tape that straddles the different knitted fabric edges; and abutting the knitted fabric edges together and bonding them together with an adhesive tape that straddles the different knitted fabric edges. In this embodiment, the joining is performed by sewing.

[0029] Furthermore, if a weft knitted fabric with a raw cut specification (which does not require edge processing after cutting) is used for the knitted fabric piece, it is not only comfortable to wear even when it comes into direct contact with the skin (reducing skin stress and pressure), but is also preferable in that the thickness of the folded edges formed for edge processing does not show through the outer garment.

[0030] Of the two or more stretchable knit fabrics, one stretchable knit fabric that forms the hemline and waistline that covers the thighs is the body knit fabric 100B in the boxer shorts 100, the body knit fabric 200B in the boxer shorts 200, and the body knit fabric 300B in the boxer shorts 300. More specifically, the hemline of the boxer shorts 100 further includes a side knit fabric S, and the hemline of the boxer shorts 200 and the boxer shorts 300 further includes a thick knit fabric TH. The reason for distinguishing the body fabric B among the three boxer shorts and boxer shorts is that the technical features of the boxer shorts and boxer shorts according to the present invention relate to the body fabric B and the shapes of the body knit fabric B among the three boxer shorts and boxer shorts are different, and other knit fabrics (for example, placket knit fabric F, side knit fabric S, thick knit fabric TH, inner thick knit fabric IN) are not (directly) related to this technical feature (approximately equivalent to "because they are less related"; this parenthetical notation will not be repeated below). Furthermore, among the two or more stretchable knit fabrics, the (single) stretchable knit fabric that forms the hemline and waistline that covers the thighs is at least the body knit fabric B that covers the buttocks, but the hemline that covers the thighs may include, in addition to the body knit fabric B, a thick knit fabric TH that forms the thick portion that covers the perineum (approximately the same as the back of the crotch; this parenthetical notation will not be repeated below). In boxer shorts 200 and boxer shorts 300 having such a thick portion, the hemline may be formed by including body knitted fabric B and thick knitted fabric TH, or the hemline may be formed by body knitted fabric 100B and side knitted fabric S without including thick portion TH as in boxer shorts 100. However, the technical features of the boxer shorts according to the present invention relate to body knitted fabric B (or body knitted fabric B and thick knitted fabric TH), but are not (directly) related to placket knitted fabric F, front body knitted fabric FF, side knitted fabric S, or inner thick knitted fabric IN.

[0031] Here, the stretchable knit fabric forming the boxer shorts 100 and 200 (which are examples of lower-body garments) can include a placket fabric F (more specifically, a placket fabric 100F for the boxer shorts 100 and a placket fabric 200F for the boxer shorts 200) that forms a bulge in the center of the abdominal side. Boxer shorts with a bulge formed by this placket fabric F are particularly preferred for men's boxer shorts because they can hold the male genitalia in an appropriate manner. By using a water-absorbent and water-repellent fabric as this placket fabric F, urine leakage can be prevented in an appropriate manner.

[0032] As shown in Figs. 1, 4 and 7, the boxer briefs 100, boxer briefs 200 and boxer shorts 300 according to the present embodiment have the following two technical features. (1) When one of two or more stretchable knitted fabrics (more specifically, body knitted fabric 100B, body knitted fabric 200B, and body knitted fabric 300B, represented by body knitted fabric B) that forms the hemline and waistline that covers the thighs is placed on a flat surface so that the waistline is approximately horizontal, the tangent to the hem apex, which is the lower end point of the hemline, is at an angle α that intersects with the vertical line (as shown in Figures 1, 4, and 7) of 35 degrees or more and 55 degrees or less.

[0033] In addition, this technical feature (2) When one of two or more stretchable knitted fabrics (more specifically, body knitted fabric 200B, body knitted fabric 300B represented by body knitted fabric B) that forms the hemline and waistline covering the thighs is placed on a flat surface so that the waistline is approximately horizontal, the straight line at the hemline that joins with thick knitted fabric TH (more specifically, thick knitted fabric 200TH, thick knitted fabric 300TH represented by body knitted fabric TH) is at an angle α of 35 degrees or more and 55 degrees or less relative to a vertical line (as shown in Figures 4 and 7).

[0034] Here, in the above-mentioned technical feature, the "straight line on the hem side that joins with the thick knitted fabric" can be easily defined when the thick knitted fabric TH is provided, but the "tangent line at the hem apex, which is the lower end point of the hem circumference" can be defined regardless of whether the thick knitted fabric TH is provided. This is because in boxer shorts 100 that do not have the thick knitted fabric TH, the "straight line on the hem side that joins with the thick knitted fabric" is too short and difficult to define as a straight line, so the technical feature is defined by the "tangent line at the hem apex, which is the lower end point of the hem circumference." And the "tangent line at the hem apex, which is the lower end point of the hem circumference" is the same (or at least approximately the same) straight line as the "straight line on the hem side that joins with the thick knitted fabric" when the thick knitted fabric TH is provided.

[0035] More specifically, the angle α shown in FIG. 3 is 43 degrees, the angle α shown in FIG. 6 is 42 degrees, and the angle α shown in FIG. 9 is 44 degrees, which satisfy the range of 35 degrees or more and 55 degrees or less, whereas the angle α in FIG. 10 shown as a comparative example is 16 degrees, which does not satisfy the range of 35 degrees or more and 55 degrees or less.

[0036] By incorporating this technical feature (limiting the angle range) (existing products are often 20 degrees or less in the range of 0 to 30 degrees), and by setting the angle to 35 degrees or more, the amount of fabric in the lower buttocks (gluteal groove) increases when joined (formed into the product shape), allowing for a three-dimensional formation (compared to existing products). For example, for the same waist circumference, the hip circumference will be longer with a larger angle, making it easier to follow the movements of the wearer's lower body (for example, moving the hip joints, bowing, moving from a standing position to a sitting position and vice versa).

[0037] Furthermore, by providing such technical features (limiting the angle range), the lower body clothing can be configured so that when a wearer wearing the lower body clothing leans forward at 45 degrees, no wrinkles will occur in the lower body clothing at a position corresponding to the wearer's buttocks, but when the wearer stands upright, wrinkles will occur in the lower body clothing at a position corresponding to the wearer's buttocks.

[0038] When wearing lower body clothing with these technical features (limited angle range), and leaning forward at 45 degrees, wrinkles do not form in the position corresponding to the wearer's buttocks (there is not enough room in the fabric to accommodate the next movement, but it is not usually possible to imagine a next movement in which the fabric of the lower body clothing around the buttocks is further pulled from this position), and the fact that wrinkles do form when the wearer stands upright means that there is enough room in the fabric to accommodate the movements of the wearer's lower body (for example, moving the hip joints, bowing, moving from a standing position to a sitting position, and vice versa). On the other hand, humans do not always maintain an upright posture in their daily lives (in fact, they spend a much larger portion of their time in positions that are not upright), so even if wrinkles occur when they are in an upright position, it is unlikely to be a major problem.

[0039] As described above, the boxer shorts according to the present embodiment can provide boxer shorts or boxer shorts, which are an example of lower-body garments that primarily cover the abdomen and buttocks, that easily adapt to the movements of the lower body and are comfortable to wear. That is, by incorporating the above-mentioned technical feature (limiting the angle range) (existing products are often in the range of 0 to 30 degrees, with most being 20 degrees or less), and by setting the angle to 35 degrees or more, the amount of fabric in the lower buttocks (gluteal crease) increases when joined (formed into the product shape), allowing for a three-dimensional shape (compared to existing products). For example, for the same waist circumference, the hip circumference at the larger angle is longer, making it easier to adapt to the wearer's lower body movements (for example, moving the hip joint, bowing, moving from a standing position to a sitting position, and vice versa).

[0040] Furthermore, a person with ordinary skill in the art (i.e., a person skilled in the art) would avoid a design that would cause wrinkles in the lower-body garment at the wearer's buttocks when the wearer is in an upright position (i.e., when the wearer leans forward at 45 degrees) while wearing the garment. It is common knowledge for a person skilled in the art that wrinkles in lower-body garments (underwear) are undesirable (they create an undesirable wearing sensation), and the reason for this is that the inventor of the present invention seeks to minimize wrinkles in all possible positions to enhance the wearing sensation of the lower body covered by the lower-body garment. However, the inventor of the present invention has transcended the design considerations within the scope of ordinary skill in the art (it is clear that this is not a mere design consideration) and arrived at a new technical concept. That is, as described above, the present invention designs a single piece of stretchable knit fabric that forms the hem and waistline that covers the thighs so that when the piece is placed on a flat surface so that the waistline is approximately horizontal, the tangent to the hem apex, which is the lower end point of the hem, or the straight line on the hem side that joins with the thick knit fabric, is at an angle of 35 degrees to 55 degrees from the vertical. As a result, when the lower body garment of the present invention is worn (no wrinkles are generated in the lower body garment at the position corresponding to the wearer's buttocks when the wearer leans forward at 45 degrees), wrinkles are generated in the lower body garment at the position corresponding to the wearer's buttocks when the wearer stands upright (there is room in the fabric), resulting in lower body garments that are comfortable to wear and easily follow the movements of the wearer's lower body (for example, moving the hip joints, bowing, moving from a standing position to a sitting position and vice versa).

[0041] It should be noted that the embodiments disclosed herein should be considered to be illustrative in all respects and not restrictive. The scope of the present invention is defined by the claims, not by the above description, and is intended to include all modifications within the meaning and scope of the claims. [Industrial Applicability]

[0042] The present invention is suitable for lower body clothing such as boxer briefs or boxer shorts (without length restrictions) that cover the abdomen and buttocks, and is particularly suitable because it easily follows the movement of the lower body and is comfortable to wear.
