Abstract
Description
Technical Field
[0001] This utility model belongs to the field of clothing technology, specifically relating to a three-dimensional leg-shaped pair of jeans. Background Technology
[0002] Traditional jeans are typically cut based on flat fabric panels, resulting in a relatively flat leg line, especially at the junction of the thigh and hip. Some jeans use stretch fabric to create a curve, but this can feel tight, while others are loose-fitting, failing to showcase the natural curves of the human body. For example, a Chinese utility model patent, "A Slim-Fit Straight-Leg Pants" (CN222548616U, 2025.03.04), discloses a slim-fit straight-leg trouser that primarily uses two cut lines to create a V-shape, visually adjusting body proportions and increasing the perceived length of the hips. However, it lacks a three-dimensional design that conforms to the natural curves of the human body at the junction of the thigh and hip. Therefore, there is a need in this field to develop jeans with a three-dimensional leg shape. Utility Model Content
[0003] To address the aforementioned issues, this invention provides a three-dimensional leg-shaped jeans, comprising a front panel, a back panel, and a waistband, wherein each back panel, when separated and laid flat, has a natural arch at the thigh section along the seam side.

[0005] In some embodiments of this utility model, the arch on the outer trouser seam is located in the section between the crotch line and the mid-crotch line.
[0006] In some embodiments of this utility model, the bulge on the side of the underwear seam is located in the section between the crotch line and the center crotch line.
[0007] In some embodiments of this utility model, the longitudinal length of the arched area on the outer trouser seam side is at least 3 / 4 of the length of the outer trouser seam side between the cross crotch line and the center crotch line.
[0008] In some embodiments of this invention, the longitudinal length of the area arched on the side of the underwear seam is at least 3 / 4 of the length of the underwear seam between the crotch line and the center crotch line.
[0009] In some embodiments of this utility model, the longitudinal length of the arched area on the outer trouser seam side is the length of the outer trouser seam side between the crotch line and the center crotch line.
[0010] In some embodiments of this utility model, the longitudinal length of the area arched on the side of the underwear seam is the length of the underwear seam between the crotch line and the center crotch line.
[0011] In some embodiments of this utility model, the lateral width of the arch on the outer trouser seam and / or the arch on the inner trouser seam does not exceed 1 / 2 of the length of the cross brace.
[0012] In some embodiments of this utility model, the arched area on the outer trouser seam side is an arc-shaped area, and the angle between the arc edge of the arc-shaped area and the edge of the outer trouser seam side of the back trouser piece is 15 to 29°.
[0013] In some embodiments of this utility model, the arched area on the side of the underwear seam is an arc-shaped area, and the angle between the arc edge of the arc-shaped area and the edge of the back underwear seam side is 15-29°.
[0014] In some embodiments of this utility model, the arch height of the outer trouser seam gradually increases along the direction from the inner trouser seam to the outer trouser seam, that is, the closer to the trouser seam, the greater the degree of arch.
[0015] In some embodiments of this utility model, the arch height of the bulge on the inner trouser seam side gradually increases along the direction from the outer trouser seam side to the inner trouser seam side, that is, the closer to the trouser seam, the greater the degree of arch.
[0016] In some embodiments of this utility model, the arching angle of the outer trouser seam is 5 to 17°.
[0017] In some embodiments of this utility model, the arching angle of the bulge on the side of the underwear seam is 5 to 17°.
[0018] In some embodiments of this utility model, the arch height of the highest point of the arch on the outer trouser seam side and / or the arch on the inner trouser seam side is 1 to 4 cm.
[0019] The beneficial effects of this utility model are as follows:
[0020] The jeans provided by this utility model have a natural arch on the thigh section of the seam between the crotch line and the mid-crotch line. When the front and back panels are joined into pants, a natural concave curve is formed at the junction of the thigh root and the buttocks, which conforms to the three-dimensional shape of the human leg. This allows the pants to form a three-dimensional shape that fits the human leg even if they are not skinny. Furthermore, by adjusting the area, height, and angle of the arch, the three-dimensional shape of the human leg can be further improved. Attached Figure Description

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "communication" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0028] This utility model embodiment provides a three-dimensional leg-shaped jeans, such as... Figure 1 and Figure 2 As shown, the jeans typically include two front panels 8, two back panels 1, and a waistband 9, which together form the complete jeans body. The joining can be done, for example, by stitching.
[0029] like Figure 1 As shown, when each of the back trouser panels 1 is in a separated and flat state, the thigh section on the trouser seam side of the back trouser panel 1 has a natural arch.
[0030] The back pant piece separation and flattening state refers to the state in which the back pant piece 1 is separated from the front pant piece 8 and lies flat on a plane, and is not pulled or pushed by external forces. The arching can be achieved by high-temperature treatment, such as ironing and pushing processes.
[0031] The natural arch of the thigh section on the seam side of the back pant piece 1 means that there only needs to be a natural arch at any position on the corresponding section of the thigh on the seam side of the back pant piece 1. For example, it can be near the crotch line 4, near the mid-crotch line 5, or at any position in the section between the crotch line 4 and the mid-crotch line 5, for example, in the middle of the section between the crotch line 4 and the mid-crotch line 5.
[0032] The trouser seam side is the outer trouser seam side 2 and / or the inner trouser seam side 3. Specifically, the thigh section of the outer trouser seam side 2 of the back trouser piece 1 has a natural arch, or the thigh section of the inner trouser seam side 3 of the back trouser piece 1 has a natural arch, or both the thigh sections of the outer trouser seam side 2 and the inner trouser seam side 3 of the back trouser piece 1 have arches.
[0033] In some embodiments, such as Figure 2 As shown, the outer trouser seam arch 6 is located in the section between the crotch line 4 and the mid-crotch line 5, and the inner trouser seam arch 7 is located in the section between the crotch line 4 and the mid-crotch line 5. That is, the outer trouser seam arch 6 and / or the inner trouser seam arch 7 can be located at any position in the section between the crotch line 4 and the mid-crotch line 5. For example, it can be located near the crotch line 4, near the mid-crotch line 5, or in the middle of the section between the crotch line 4 and the mid-crotch line 5.
[0034] The arched portion in this application corresponds to the area where the upper thigh meets the buttocks. Because denim fabric is soft, after the front and back panels are sewn together, the arched portion, constrained by the front panel, actually appears to be concave inwards when worn. Figure 3 As indicated by the middle arrow. Compared to using a flat back panel, it better conforms to the natural concave curve of the connection between the upper thigh and buttocks when the human body is standing, forming a more three-dimensional shape that conforms to the natural shape of the human leg. This allows the pants to form a more three-dimensional shape that fits the human leg shape even if they are not fitted.
[0035] Furthermore, the longitudinal length M1 of the area of the arched region 6 on the outer trouser seam side is at least 3 / 4 of the length of the outer trouser seam side between the crotch line 4 and the center crotch line 5, and / or, the longitudinal length M2 of the area of the arched region 7 on the inner trouser seam side is at least 3 / 4 of the length of the inner trouser seam side between the crotch line 4 and the center crotch line 5. The longitudinal length M1 of the area of the arched region 6 on the outer trouser seam side is the length of the area of the arched region 6 on the outer trouser seam side along the direction of the outer trouser seam; the longitudinal length M2 of the area of the arched region 7 on the inner trouser seam side is the length of the area of the arched region 7 on the inner trouser seam side along the direction of the inner trouser seam.
[0036] Specifically, the bulge 6 on the outer trouser seam side and / or the bulge 7 on the inner trouser seam side are located within the section between the crotch line 4 and the mid-crotch line 5. They can be at any position within this section, provided that the longitudinal length of the area of the bulge 6 on the outer trouser seam side is greater than or equal to 3 / 4 of the length of the outer trouser seam side between the crotch line 4 and the mid-crotch line 5, and the longitudinal length of the area of the bulge 7 on the inner trouser seam side is greater than or equal to 3 / 4 of the length of the inner trouser seam side between the crotch line 4 and the mid-crotch line 5. For example, the longitudinal length of the bulge 6 on the outer trouser seam side can be only 3 / 4 of the length of the outer trouser seam side between the crotch line 4 and the mid-crotch line 5, or it can be greater than 3 / 4 of the length of the outer trouser seam side between the crotch line 4 and the mid-crotch line 5. Similarly, the longitudinal length of the bulge 7 on the inner trouser seam side can be only 3 / 4 of the length of the inner trouser seam side between the crotch line 4 and the mid-crotch line 5, or it can be greater than 3 / 4 of the length of the inner trouser seam side between the crotch line 4 and the mid-crotch line 5.
[0037] Preferably, the longitudinal length M1 of the area of the bulge 6 on the outer trouser seam side is the length of the outer trouser seam side between the crotch line 4 and the mid-crotch line 5, and / or, the longitudinal length M2 of the area of the bulge 7 on the inner trouser seam side is the length of the inner trouser seam side between the crotch line 4 and the mid-crotch line 5.
[0038] like Figure 2 As shown, the lateral width N1 of the bulge 6 on the outer trouser seam side does not exceed 1 / 2 of the length of the crotch line 4, and / or, the lateral width N2 of the bulge 7 on the inner trouser seam side does not exceed 1 / 2 of the length of the crotch line 4. The lateral width N1 of the bulge 6 on the outer trouser seam side is the width of the area of the bulge 6 on the outer trouser seam side in the direction perpendicular to the extension direction of the outer trouser seam; the lateral width N2 of the bulge 7 on the inner trouser seam side is the width of the area of the bulge 7 on the inner trouser seam side in the direction perpendicular to the extension direction of the inner trouser seam.
[0039] Furthermore, the area 6 arched on the outer trouser seam side is an arc-shaped area, and the angle β1 between the arc edge of the arc-shaped area and the edge of the outer trouser seam side 2 of the back trouser piece can be 15 to 29°. The area 7 arched on the inner trouser seam side is an arc-shaped area, and the angle β2 between the arc edge of the arc-shaped area and the edge of the inner trouser seam side 3 of the back trouser piece can be 15 to 29°.
[0040] Preferably, the arc-shaped area of the region arched on the outer trouser seam side 6 is an axisymmetric figure, with its axis of symmetry L1 perpendicular to the edge of the outer trouser seam side 2; and / or, the arc-shaped area of the region arched on the inner trouser seam side 7 is an axisymmetric figure, with its axis of symmetry L2 perpendicular to the edge of the inner trouser seam side 3.
[0041] Furthermore, such as Figure 1 As shown, the arching angle α1 of the outer trouser seam arch 6 can be 5–17°; and / or, the arching angle α2 of the inner trouser seam arch 7 can be 5–17°. The arching angle refers to the angle between the arched edge of the trouser seam and the flat plane when the back trouser piece is separated from the front trouser piece 8 and laid flat on a plane.
[0042] The height h1 of the highest point of the arch on the outer trouser seam side 6 can be 1 to 4 cm, and / or the height h2 of the highest point of the arch on the inner trouser seam side 7 can be 1 to 4 cm. The arch height refers to the distance between the highest arch point and the flat plane when the back trouser piece is separated from the front trouser piece 8 and laid flat on the plane.
[0043] The back panel of the pants may also have patch pockets, slip pockets, three-dimensional pockets, flap pockets, zippered pockets, etc.
[0044] This utility model creates a natural arch on the side of the trouser seam between the horizontal crotch line 4 and the middle crotch line 5, and further adjusts the arch area, arch height, and arch angle so that when the front trouser piece 8 and the back trouser piece 1 are connected to form trousers, they form a three-dimensional shape that better conforms to the natural shape of the human leg.
[0045] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
