BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be specifically described below with reference to the drawings. FIG. 1 is a perspective view showing a denim pants sewn according to the present invention, and FIG. 2 is a detailed view of an essential part showing a slide fastener stitched portion on the back side of the denim pants shown in FIG. Further, 1 is a denim pants body on which the method of the present invention has been carried out, and the broken line shows the seam of the main part. This denim pants 1 is a fastener type denim pants whose front opening is opened and closed by a slide fastener 2. Then, the slide fastener 2 is sewn by the following procedure.

Slide fastener 2 used in the present invention
Is a well-known device, in which the articulator 4 is continuously attached to the facing portions of the two left and right tape base fabrics 3 and 3'which are butted to each other, and the end stoppers 5 are fixedly attached to the ends thereof. It is a thing. The materials of the articulator 4 and the end stopper 5 are not particularly limited, and those made of thermoplastic resin or metal are used.

As shown in FIG. 2, the slide fastener 2 is sewn on the right and left front body cloths 1a and 1b of the denim pants 1 with the facing cloth 6 and the carry-out cloth 7 interposed therebetween. At this time, the seam allowance is performed so that the seam allowance portions 6 ', 7'of the facing cloth 6 and the carry-out cloth 7 are not exposed.

When the facing cloth 6 is sewn, one end 6 of the facing cloth 6 is sewn.
Although a is sewn on the side end portion (a) of the left front body cloth 1a in the same manner as in the conventional case, the other side end portion 6b is covered with the left tape base cloth 3 of the slide fastener 2 in the present invention. Make them sew. At this time, both side edges of the left tape base cloth 3 are fastened, and the other side end portion 6b is housed between the fastening. Therefore, the seam allowance portion 6'of the facing cloth 6 is not exposed at all on the back side of the left front body cloth 1a. In order to reinforce the cloth at the facing part, an adhesive core may be provided on the back surface of the facing cloth 6.

As shown in FIG. 3, the carry-out cloth 7 has a strip-shaped cloth in which the lower end is formed in an inverted M-shape, and the seam margin portion 7'of its periphery is folded inward except for the upper end and one side end. The folding parts 8a, 8b, 8c ... Here, the dashed-dotted lines a, b, c ... Show the bending lines at that time. That is, the carry-out cloth 7 is folded in two in the longitudinal direction at the folding line e at the substantially center, and the folding portions 8a, 8b, 8c ... Are folded inwardly and disposed on the surface side of the denim pants. Front carry-out portion 7a (without a folding portion at the side end)
And, it is sewn to the right front body cloth 1b as a back carry-out portion 7b arranged on the back side. Here, when the carry-out cloth 7 is sewn, as shown in FIG. 4A, the outer peripheral edge of the back carry-out cloth 7b is folded inward except for the upper end portion. The cut edges of the take-out cloth 7 are not exposed at all.

Further, when the above-mentioned folded portion is to be folded, FIG.
As shown in Figure 4, at the tip of the carry-out portion, only four pieces of cloth are overlapped at most.
The carry-out parts 7a and 7b and the folding parts 8a and 8b,
The width of 8c ... can be arbitrarily designed, but for example, the width of the front carry-out part 7a is 2.8 cm, the width of the back carry-out part 7b is 3.0 cm, and the width of the folding part 8a is 4 mm. The width of 8b is 4mm and the width of 8c is 8mm.
The width of 8 mm and the width of 8 mm is about 8 mm, which is preferable because the gauge width (6.4 mm) of a generally used sewing machine can be used. Here, the corners 7a ′, 7 at the lower left and right ends of the carry-out cloth 7
The b'is cut inwardly in a triangular shape (shown by a two-dot broken line) so that the leading end (b) of the carry-out cloth 7 is not bulky with the folded cloth. The triangular piece has a vertical q and a horizontal r
The dimensions are about 1 cm to 2 cm, respectively. Further, in order to make it easier to fold the tip portion (b), it is advisable to make cuts s, s on the extension lines of the bending line c with respect to the folding parts 8b and 8d.

The carry-out cloth 7 is brought into contact with the back surface of the right front body cloth 1b so as to project from the front open side end c, and the right tape is provided between the two along the side end (c). The articulator 4 of the base cloth 3'is exposed so that the base material 3'is sewn. At this time, first, these three cloths are sewn at the side end (C) of the right front body cloth 1b, and then, on the back surface side of the denim pants 1, the back carry-out portion 7b is fixed to the right tape base cloth 3 '. The open side end (d), the folded back seam allowance part (e) of the right front body cloth 1b and the open side end (f) of the front carry-out part 7a are covered with the right front body cloth 1b and abutted on the back surface thereof. The inside of the folding line d is sewn m ″. Since the carry-out cloth 7 is formed here as described above, each folding portion is not bulky and can be accommodated inside thereof. The fastener sewn portion has an extremely excellent appearance without exposing the cut lines of the respective cloths, in combination with the disposing of the seam of the facing cloth 6.

The stitching u of the left and right front body cloths 1a and 1b at the crotch portion is such that the seam allowance width of the left front body cloth 1a is about 8 mm, and the seam allowance width of the right front body cloth 1b is about twice that of 1.6 mm. Then, it is performed by a well-known folding seam technique. At this time, the seams of the folding stitch method are sewn so as to be formed on the extension lines of the seams when the carry-out cloth 7 is sewn. Next, at the opening stop position p of the left front body cloth 1a, a so-called knit stop stitch t is performed through the right front body cloth 1b to the carry-out cloth 7 at a position below the end stopper 5. (Usually, the open side end of the take-out cloth is overlapped with the facing cloth side, and the second can stop t'is made (see FIG. 7)). Here, in the method of the present invention, since the lower end portion of the carry-out cloth 7 at the time of sewing is made a pointed end, even if it is not intentionally sewn to the cloth 6 to look up the open side end portion, a feeling of strangeness is felt during wearing. I don't feel it. vice versa,
Since the carry-out cloth 7 does not straddle the fastener 2, the opening and closing of the fastener can be performed much more smoothly than before.

Next, as shown in FIG. 5, the flap 9 is sewn to the side end portion (a) of the left front body cloth 1a and can be detachably attached to the right front body cloth 1b across the fastener portion. , Underwear should not be exposed even if the fastener breaks down while wearing and is in the open state. Further, when the flap 9 is attached to the right front body cloth 1b, the flap 9 appropriately presses the abdomen of the wearer. The flap 9 can be designed arbitrarily, but a specific example thereof is shown below.

The flap 9 is, for example, three sides 9a, 9b, 9
It has a triangular shape made of c, and one side 9a thereof is sewn to the side end portion (a) of the left front body cloth 1a together with one side end portion 6a of the facing cloth 6. At this time, the dimensions of the three sides are 9a = 1, respectively.
The length is about 6 cm, 9b = 8 cm, and 9c = 20 cm, or doubled to increase the abdominal pressing force. The front front body cloth 1b is attached and detached by attaching a pair of end stop snaps 10 to the back surface of the flap 9 on the open end side and the front surface of the right front body cloth 1b, respectively.
At this time, any number of the end stop snaps 10 can be attached, but if at least two sets are attached, the above-mentioned pressing effect can be efficiently exhibited. In the present invention,
In order to improve the design effect of the denim pants, the shape and size of the flap 9 or the number of the end snaps 10 and the attachment points may be appropriately designed.

As shown in FIG. 6, the side pocket 11 is composed of a front body cloth 1a (1b) and a side cloth 12.
First, the surface of the side cloth 12 made of the same material as the body cloth and having a uniform shape is brought into contact with the back side of the front body cloth 1a (1b), and the periphery of the front body cloth is sewn except for the pocket mouth and the side end. u'do. Then, the side edge of the side cloth 12 is sandwiched between the side body seams of the front body cloth 1a (1b) and the back body cloth to form the side pocket 11.
Since the side pocket 11 does not have a conventional pocket bag cloth, the pocket bag cloth does not flip up when worn, and the hand can be smoothly put in and taken out between the front body cloth and the side cloth. Becomes It also has a certain degree of tension and does not cause any problem of losing its shape.

Further, end stop snaps 10 are attached to both ends of the belt cloth 13 at the upper end of the front opening to fix the belt portions (see FIG. 2). The number of the end stop snaps 10 can be arbitrarily designed, but normally, 1 to 4 are attached, and when the number is 2, the end stop snaps 10 are arranged in tandem with the end of the belt cloth 13. As compared with the conventional button or L-type metal fitting fastening method, the denim pants can be easily attached and detached because they can be easily removed with one hand. Further, since the end stop snap 10 exhibits rigidity against the pulling force in the left-right direction, it does not come off even if the abdomen is tightly tightened, and the button does not fly off.

The denim pants sewn by the method of the present invention can be easily opened and closed at the front opening,
In addition, there is no problem such as loosening from the fastener sewn portion, and the fitting feeling when worn is excellent.

[0031]

As described above, the present invention is constructed as described above. The denim pants sewn according to the present invention have extremely high robustness against frequent washing and do not become distracted when worn. You can wear it with confidence. In particular, since the seams of the fasteners are tidily arranged, the wearer does not feel uncomfortable while wearing the wearer, and the wearer can wear it as a fashionable clothes because it also develops a sense of quality. Further, the one to which the flap is attached can be worn for body shape correction by the abdominal portion pressing effect of the flap. Therefore, the product of the present invention exerts a remarkable effect in that the denim pants can be fitted with a fit and smartness according to the purpose of the wearer, and can provide a much wider range of use than conventional ones.
