Description

Technical Field

[0001] The present invention relates to trousers capable of adjusting the inseam length.

Background Art

[0002] Conventionally, when the inseam length of the purchased trousers does not fit, the hem is raised according to the wearer. This hem raising is done by sewing, which takes time and cannot be worn immediately. To address this, for example, Patent Document 1 discloses trousers capable of easily adjusting and changing the inseam length of the trousers.

Summary of the Invention

Problems to be Solved by the Invention

[0004] According to the technique of Patent Document 1, a space is opened between the portions of the front and rear crease lines, and a pair of core materials are attached to the left and right of the hem opening. The crease line is a line pressed into the center of the front and rear body parts of the trousers and is also called the center press. The front and rear crease lines are located on the diameter line of the hem opening. According to this technique, a pair of core materials are attached while avoiding the front and rear crease lines. The core materials are attached across the inner thigh line and the side seam that sew the front and rear body parts. Due to the hardness of the core materials, they are linear at the positions of the inner thigh line and the side seam and can be folded at the positions of the front and rear crease lines.

[0005] On the other hand, there are also trousers without crease lines before and after. For example, trousers such as denim pants, and after washing, many are everyday trousers that are reused as they are without ironing. In such trousers without crease lines, it is arbitrary which line in the length direction of the trousers to fold the hem, and it is not necessarily folded at the center position with a crease line.

[0006] Therefore, when a pair of core materials are arranged with a crease line sandwiched between them as in the prior art for trousers without crease lines before and after, the folding position is only at the position of the crease line. If it is folded at another position, the core material will break. This makes it difficult to display the trousers flat. Thus, an object of the present invention is to provide trousers that can easily adjust the crotch dimension and can be naturally folded when the trousers are displayed flat.

Means for Solving the Problem

[0007] To achieve the above object, the trousers of the present invention have a pair of strip-shaped core materials attached on the same circumference along the circumferential direction at the hem, One of the pair of core materials is attached to the front body side, and its front and rear ends protrude to the rear body side beyond the side seam and the inner thigh line, The other core material has its front and rear ends attached only to the rear body side with a space from the front and rear ends of the one core material, The positions where the front and rear ends of each of the pair of core materials are spaced apart are pressed as press positions, and have side folds and inner thigh folds passing through the gaps along the vertical direction from the hem. Also, the seam allowance of the side seam is turned to the rear body side, and the seam allowance of the inner thigh line is turned to the front body side, and the side folds and the inner thigh folds are provided at positions that do not overlap with the seam allowance of the side seam and the seam allowance of the inner thigh line. And each of the pair of core materials is an inverted V-shaped core cut into a trapezoid having an upper edge shorter than the lower edge, further formed into an octagon with the four corners of the trapezoid diagonally cut off, attached inside the hem allowance, the fabric at the lower end of the hem allowance is folded toward the pair of core materials, the pair of core materials are folded back along the hem finishing line to form a hem, and the stitching line for stitching the hem allowance is at a position intersecting the sides where the left and right corners of the upper edge of the inverted V-shaped core are diagonally cut off.

Advantages of the Invention

[0008] According to this device, by folding back the hem part with the core material, the inseam length can be easily adjusted, and it can be naturally folded when laid flat on the front of the trousers. Also, since the four corners of the core material are cut off, it is possible to reduce damage to the fabric.

Embodiments for Carrying Out the Invention

[0010] Hereinafter, the trousers according to the present invention will be described with reference to the drawings. The trousers 1 are trousers without crease lines. In FIG. 1, the trousers 1 are composed of a front body 2, a back body 3, a waist part 4, etc. The front body 2 and the back body 3 are sewn together by side seams 5 and inner thigh seams 6, respectively forming a stitching line. A hem opening 9 is formed at the lower end of the trousers 9. In trousers without crease lines, it is common for the width of the back body 3 to be longer than the width of the front body 2. Therefore, when the back body 3 and the front body 2 are sewn together by the side seams 5 and the inner thigh seams 6, the side seams 5 and the inner thigh seams 6 do not exist at the opposing positions on the diameter line of the hem opening 9 formed in a tubular shape. Also in the figure, both the side seams 5 and the inner thigh seams 6 are visible on the front of the trousers 1. Since there are no crease lines, for the purpose of displaying as a product, etc., after the trousers 1 are tailored, side creases 7 and inner thigh creases 8 are made by pressing.

[0011] FIG. 2 is an enlarged explanatory view of the state before attaching the core material at the hem opening 9 of the trousers. FIG. 2A is a perspective view, and FIG. 2B shows the state where the sleeve part 9 is cut along the inner thigh seam 6 and unfolded. The dashed line in the figure is the hem finishing line 10, and the parts of the front body 2 and the back body 3 below it become the sewing allowance 11 of the hem opening 9. The sewing allowance 12 of the side seam 5 is folded to the back body 3 side, and the sewing allowance 13 of the inner thigh seam 6 is folded to the front body 2 side. The width dimension w1 of the front body 2 at the hem finishing line 10 is shorter than the width dimension w2 of the back body 3. Therefore, the side seam 5 and the inner thigh seam 6 do not exist at the opposing positions on the diameter line when the hem opening 9 is formed in a circular shape. The two-dot chain line in the figure indicates the fold line when laid flat. The position of the side crease 7 is set to a position that enters the back body 3 from the sewing allowance 12 of the side seam 5. Also, the inner thigh crease 8 is set to a position that opposes the side crease 7 on the diameter line of the hem opening 9. The side crease 7 and the inner thigh crease 7 are pressed and attached to the trousers 1 after finishing. FIG. 2C is the state where it is cut and unfolded along the inner thigh crease 8 of the hem opening 9, and the width dimension w3 (front body 2 side) and the width dimension w4 (back body 3 side) at the hem finishing line 10 from the side crease 7 to the inner thigh crease 8 are equal.

[0012] FIG. 3 shows an example in which the fabric is folded in three at the hem 9, and is an enlarged development explanatory view showing the process of sewing the hem 9. To explain the sewing state of the hem 9, the hem 9 is cut and unfolded along the inner crotch fold line 8, and the hem 9 is enlarged and shown. In FIG. 3A, a pair of core materials 14-1 and 14-2 are strip members made of synthetic fiber woven fabric, and an invel core used for the waist portion of trousers, skirts, etc. is used. The core materials 14-1 and 14-2 are of the same shape, and the width dimension w4 is 28 mm. The lengths of the core materials 14-1 and 14-2 are such that when the hem 9 is folded inward, it has a length that can fold back the entire circumference of the hem 9. The core materials 14-1 and 14-2 are formed in an octagon with the corners of the strip member cut diagonally.

[0013] In FIG. 3A, the core materials 14-1 and 14-2 are attached to the sewing allowance 11 with an adhesive. The core material 14-1 is attached to the oil residence city 11 on the front body 2 side, with its front and rear ends protruding from the side line 5 and the inner crotch line 6 to the back body side. Also, the core material 14-2 is attached only to the back body 3 side with a gap between its front and rear ends and the front and rear ends of the core material 14-1.

[0014] The core materials 14-1 and 14-2 are arranged along the same circumference in the circumferential direction inside the sewing allowance 11. Two gaps 15 are formed between the front and rear ends of the pair of core materials 14-1 and 14-2. The two gaps 15 are provided at positions that enter the back body 3 side from the side line 5 and the inner crotch line 6 of the hem 9. The side fold line 7 passes through the side gap 15, and the inner crotch fold line 8 passes through the inner crotch gap 15. And the positions of the side fold line 7 and the inner crotch fold line 8 are set so as not to overlap with the sewing allowance 12 folded down to the back body 3 side and the sewing allowance 13 folded down to the front body 2 side, so that the formation of the side fold line 7 and the inner crotch fold line 8 by pressing is stabilized. Incidentally, the side fold line 7 and the inner crotch fold line 8 gradually disappear depending on the usage situation of consumers who do not use an iron.

[0015] The core materials 14-1 and 14-2 are trapezoids with their widthwise ends cut diagonally. Among the lengths from the fold line to the ends of the core material 14, the shorter width dimension w5 is 2 mm, and the longer width dimension w6 is 5 mm.

[0016] Figure 3B shows a state in which the fabric at the lower end of the hem allowance 11 is bent toward the core materials 14-1 and 14-2, and Figure 3C shows a state in which the core materials 14-1 and 14-2 are folded and sewn along the hem finishing line. In order to triple-fold the fabric at the hem opening 9, the width of the hem allowance is set to about 1.5 times the width of the core material. As shown in the figure, the lower end of the hem allowance 11 is folded back so as to wrap the core materials 14-1 and 14-2. In this state, the core materials 14-1 and 14-2 are folded back along the hem finishing line 10, and the upper ends of the respective core materials 14-41 and 14-2 are sewn to the front and back body pieces 2 and 3. In this way, the hem portion 9 is formed at the lower end of the trousers 1. Thereafter, it is pressed, side creases 7 and inner thigh creases 8 are made, and it is packed and displayed as a product.

[0017] Using Figure 4, the core materials 14-1 and 14-2 will be described in more detail. The core materials 14-1 and 14-2 are formed of an invel core. The invel core is provided in a strip shape in a reel-wound state (Figure 4A). The strip-shaped invel core is cut to the required length. At that time, the end portions in the width direction are cut obliquely to form a trapezoid (Figure 4B). The lower base side (referred to as the lower edge portion) of the trapezoid is longer than the upper base side (referred to as the upper edge portion). Further, the four corners of the trapezoid are cut obliquely (Figure 4C). As a result, the core materials 14-1 and 14-2 are formed with sides 14a, 14b, 14c, and 14d from which the four corners of the trapezoid are cut obliquely. The core materials 14-1 and 14-2 are inside the hem allowance 11, and the front and back body pieces 2 and 3 of the trousers 1 and the upper edges of the core materials 14-1 and 14-2 are sewn together, but the sewing line 16 is sewn so as to intersect the obliquely cut sides 14a and 14b of the core material 14 (Figure 4D). When the four corners of the core material are cut off, new corners s and t will be formed, but by passing the sewing line 16 between the corners s and t, it is possible to hold between both corners s and t. Even if the strength of the adhesive for fixing the core materials 14-1 and 14-2 to the trouser fabric decreases, it is possible to reduce the core materials 14-1 and 14-2 from peeling off starting from the corner s or the corner t.

[0018] In the finished state of Fig. 4D, the lower edges of the core materials 14-1 and 14-2 are located on the lower side, and the upper edges are located on the upper side. The sewing line 16 for sewing the fabric of the hem 9 and the core materials 14-1 and 14-2 will sew the upper edge side. When applying the sewing line 16, it is possible to cope with the elongation of the core materials 14-1 and 14-2.

[0019] Fig. 5 is a partial explanatory view showing the use state of the trousers 1. Fig. 5A shows the state where the hem 9 is not folded back, and Fig. 5B shows the state where it is folded back once inside. When the hem 9 is folded back, the inseam dimension becomes shorter by a dimension slightly larger than the width dimensions of the core materials 14-1 and 14-2. Since the invel core used for the core materials 14-1 and 14-2 has excellent shape retention, it can maintain the folded state without bending just by folding back. If necessary, the hem part is folded back two or three times to lift the hem.
