Forms a groove for sewing along the longitudinal direction, the locking projection of the adjuster rail has a locking wall and a guide slope, and the adjuster body is made of a metal plate material wider than the width of the adjuster rail. A stopper is provided as an engaging / disengaging means with respect to the locking protrusion, and a sewing piece made of a synthetic resin plate is fixed to each of the left and right sides of the locking body, and the locking body slides on the left and right side portions of the adjuster rail. A waist tone characterized by having a guide claw body that is movably held, a locking claw body that engages with a locking wall of a locking projection, and an operation lever for engaging and disengaging operation. The use adjuster is for a means for solving the problems.

  According to the present invention, with the above-described configuration, the engagement piece of the engagement body made of a metal plate material and the guide claw body are fitted between the left and right sewing plates in a slidable manner with the adjuster rail, and the engagement Since the stopper piece abuts on the locking wall of the locking projection of the adjuster rail, the adjuster rail and the adjuster main body can be locked, and the engaging / disengaging operation can be performed by pressing the operating lever of the locking body. While ensuring the basic sliding and engaging / disengaging functions of the waist adjusting adjuster, the overall volume including the adjuster and the adjuster rail can be made very low (that is, very thin).

  Further, in the present invention, since the sewing piece and the slide rail can be sewn to the cloth, respectively, conventionally, the adjuster main body such as the adjuster main body disclosed in Patent Document 1 is conventionally used. It is not necessary to use a metal nail member that is necessary for fixing the fabric to the fabric, and therefore, it is not necessary to perform the caulking work of the nail member, and for waist adjustment with respect to the waist portion of the garment only by sewing. You can install an adjuster.

  On the other hand, as described in claim 2, when the adjuster rail is formed with a central rail having a bulk higher than the locking projection at the longitudinal center, the adjuster body slightly increases in volume, but the adjuster main body is the adjuster rail. Since contact with the fabric on the attachment side can be prevented, smoother adjuster sliding can be realized.

  In addition, as described in claim 3, when a plurality of concave portions for bending are formed in the central rail, the flexibility of the concave portion for bending is improved as compared with other locations. The flexibility can be remarkably improved, and the durability of the adjuster rail can be greatly improved.

  Furthermore, as described in claim 4, when the sewing groove is formed in the lateral direction at the end of the adjuster rail, the sewing groove is sewn to the fabric with the sewing thread. Since the thread prevents the adjuster body from falling off, it is possible to ensure the functions required for the waist adjustment adjuster only by sewing without specially providing a stopper to prevent the adjuster body from falling off the adjuster rail. it can.

  According to a fifth aspect of the present invention, the locking body in the adjuster body includes connecting tongue pieces on the left and right sides, the connecting tongue pieces are formed with engaging holes, and the sewing pieces are formed in the opening portion. A tongue piece engaging space having an engagement piece, and an engagement protrusion provided in the tongue piece attachment space, and the engagement protrusion piece is fixed to the engagement hole of the connecting tongue piece in a state where it cannot be removed. Since the connecting tongue of the locking body is inserted into the engagement space from the opening of the sewn piece, and the engagement hole and the engagement protrusion are engaged, It is possible to securely and easily fix the metal locking body, which is the material, and the synthetic resin sewing piece.

  Furthermore, as described in claim 6, when the locking body in the adjuster main body is configured to connect the left and right connecting tongue pieces with a belt-like plate, the adjuster main body has a large lateral deflection, Since it can adapt to bending of cloths, such as clothes, a natural feeling without a sense of incongruity can be given to a wearer.

  Further, as described in claim 7, when the sewing piece in the adjuster main body is formed with a sewing groove, an appropriate sewing line can be known more easily, and efficiency and product quality during sewing can be obtained. Since the stitching groove itself is formed to be very thin, the sewing operation can be further facilitated, and the occurrence of breakage of the needle during suturing can be reduced. Can do.

  Further, as described in claim 8, when the side wall of the locking projection is configured to guide the guide claw body in the longitudinal direction, the guide claw body can be formed only by guiding the right and left edges of the adjuster rail. There is a possibility that a problem of being caught on the adjuster rail in the tilted state may occur, but the problem is prevented by always guiding the guide claw body in the longitudinal direction, and the adjuster body can be slid more smoothly.

  In the present invention, the adjuster rail forms a sewing groove in the longitudinal direction, the engaging projection of the adjuster rail has an engaging wall and a guide slope, and the adjuster body is wider than the width of the adjuster rail. And a latching piece made of a synthetic resin plate is fixed to each of the left and right sides of the locking body. The locking body is an adjuster rail.

Thus, the adjuster body 2 is slidable with respect to the adjuster rail 1.

  Next, the procedure and structure for attaching the adjuster for waist adjustment according to the embodiment of the present invention will be described. In the present embodiment, an example in which a waist adjustment adjuster is provided with respect to the front left and right positions of the waist portion of the trousers is shown. However, since the attachment of the waist adjustment adjusters is symmetrical, only the front left side of the trousers is shown. Will be described.

  As shown in FIG. 14, the waist portion of the trouser includes an outer fabric 3 and an inner fabric 4, and the waist is adjusted by adjusting the overlap between the outer fabric 3 and the inner fabric 4. Accordingly, a waist adjusting adjuster is disposed between the inner surface of the outer fabric 3 (hereinafter, outer fabric inner surface 30) and the outer surface of the inner fabric 4 (hereinafter, inner fabric outer surface 40). In this embodiment, the adjuster body 2 is disposed on the outer fabric inner surface 30, and the adjuster rail 1 is disposed on the inner fabric outer surface 40.

In the mounting procedure in this embodiment, first, the adjuster rail 1 and the adjuster body 2 are handled in a separated state. The adjuster rail 1 is arranged on the inner fabric outer surface 40 in such a direction that the locking projection 12 abuts against the inner fabric outer surface 40 (that is, the back surface is in contact with the inner fabric outer surface 40 and hidden). Sewing against. The sewing portion is performed on the sewing groove 14a in the center of the longitudinal direction and the sewing groove 14b in the distal direction.
As described above, the exposed front sewn groove is formed as a groove that is slightly wider and deeper than the sewn groove on the back side, which makes the sewing work easier.

  On the other hand, the adjuster body 2 is sewn by bringing the front side of the sewing piece 21 into contact with the outer fabric inner surface 30. The sewing position is performed with respect to the sewing groove formed in the sewing piece 21.

  With the adjuster body 2 attached to the inner surface of the outer fabric, the adjuster body 2 is inserted from the other end of the adjuster rail 1 and the adjuster rail 1 and the adjuster body 2 are attached.

After the adjuster body 2 is attached to the adjuster rail 1, the other end of the adjuster rail 1 is further covered with a cloth, and the other end of the adjuster rail 1 is sandwiched between the inner cloth outer surface 40 and sewn.
In addition, this attachment procedure is shown as an example, and this invention is not limited to this attachment procedure.

  With the above attachment procedure, the attachment structure of the adjuster for waist adjustment according to the present embodiment can be configured. In a normal wearing state, as shown in a schematic diagram showing the relationship between the locking body 20 and the adjuster rail 1 in FIG. 15, the mounting structure holds the state where the adjuster rail 1 and the adjuster body 2 are locked. Yes.

Here, as described above, the adjuster rail 1 is sewn to the inner fabric outer surface 40 as the direction in which the locking projection 12 contacts the inner fabric outer surface 40 with respect to the inner fabric outer surface 40. The adjuster rail 1 is curved with the concave portion 13 for bending inside along the wearer's waist. The curve is curved in a direction that is symmetric (opposite side) with respect to the warping direction of the operation lever 22, so that the engagement edge portion 28 a of the operation lever 22 bites into the engagement protrusion 12. The locking state of the adjuster for adjusting the waist is made stronger.

  Even in this state, the locking claw body 29 is guided by the guide surface of the locking projection 12 in the direction of tightening the waist, so that the adjuster body 2 can be moved without adjusting the operation lever 22. 1 can be slid against some frictional resistance due to the locking projection 12.

  Then, in order to release the lock between the adjuster rail 1 and the adjuster main body 2, as shown in FIG. 16, by pressing the operating lever 22, the locking claw body 29 formed integrally with the operating lever 22 is pressed. This can be done by separating the locking edge 28a from the locking projection 12 on the adjuster rail 1.

  On the other hand, with respect to the slide of the adjuster body 2 in the direction of loosening the waist part of trousers or the like, as described above, by pushing the operating lever 22, the locking claw body 29 formed integrally with the operating lever 22 is locked. The edge 28a is separated from the locking protrusion 12 on the adjuster rail 1, so that the lock between the adjuster rail 1 and the adjuster main body 2 is released, which can be realized. The release operation and the slide operation can be easily performed by a series of operations by sandwiching the outer fabric 3 and the operation lever 22 with a finger and sliding them.

  Here, since the adjuster body 2 has a flexible structure in which the sewing piece 21 is connected by two belt-like plates, that is, the front frame 23 and the middle frame 24, the center is simply curved with respect to the left and right ends. The movement of twisting the left and right connecting tongue pieces 20b is allowed. Therefore, the wearer can bend freely with respect to various loads acting on the waist portion of clothes, etc., and the wearer can wear the waist adjustment adjuster with a natural feeling without causing any discomfort. The outstanding effect that it can wear etc. can be exhibited.

  Further, as described above, the operation lever 22 is provided with the two rear frames 25 orthogonal to the middle frame 24 and the pressing portion 26 formed at the rear end of the rear frame 25, so that the operation lever 22 itself is elastic. To reduce the burden on the wearer when pressing with a finger. Further, the rear half of the pressing portion 26 of the operation lever 22 is wider than the front half, thereby increasing the contact area with the finger, thereby improving the operability.

  Further, the thin plate-like front frame 23, middle frame 24, and operation lever 22 of the adjuster body 2 are disposed below the adjuster rail 1, and a guide claw body 27 and a locking claw body 29 are slightly positioned above the adjuster rail 1. As a result, the thickness of the adjuster itself for adjusting the waist including the adjuster rail 1 has been very thin.

  Further, with respect to both the adjuster body 2 and the adjuster rail 1, the sewing groove is formed in each part (that is, the sewing piece 21 of the adjuster body 2, the front side and the back side of the adjuster rail 1), and the adjuster body 2. Since the very thin sewing piece 21 is formed, it can be attached to the fabric along the sewing groove only by sewing.

  In the present embodiment, the tip of the adjuster rail 1 is directly sewn to the fabric, and the other end is covered with the covering fabric and sandwiched between the inner fabric outer surface 40 and sewn, but the present invention is not limited to this. Alternatively, both ends can be sewn using a contact fabric, and both ends can be sewn directly so that the sewing thread penetrates the adjuster rail 1. In the case of the present embodiment, it is not necessary that the adjuster body 2 is removed from the tip side at all, while the other end side must pass the adjuster rail 1 when the adjuster body 2 is attached to the adjuster rail 1. On the premise that there is a certain thing, a highly efficient attachment method is used on the tip side, and an attachment method that makes the appearance appearance good on the other end side.

  By forming the bending recess 13, the central rail 11 can be bent so as to fill the bending recess 13, and the flexibility of the adjuster rail 1 can be improved.

  In the above-described embodiment, the adjuster body 2 has a configuration in which the sewing piece 21 is connected by two belt-like plates, that is, the front frame 23 and the middle frame 24. However, in the present invention, the belt-like plate for connecting the sewing piece 21 is used. Is not limited to two, but may be one or more than three, and the belt-like plates are not limited to being parallel to each other, but are crossed or have a single center and two ends. It can also be a thing to do.

  Moreover, in the said Example, although the sewing groove | channel is formed in each part of both the adjuster rail 1 and the adjuster main body 2, in this invention, not all the sewing groove | channels are necessarily required, but the adjuster rail 1 The adjuster body 2 itself can be made sewn by forming it thin.

  Furthermore, in the said Example, although it is set as the structure which formed the several recessed part 13 for bending in the center rail 11, this invention is not limited to the said structure, Even if it does not form the recessed part 13 for bending. Good.

As shown in FIGS. 17 and 18, the function of the adjuster for waist adjustment can also be exhibited by turning the adjuster body 2 in the reverse direction. In this case, unlike the above-described embodiment, unlike the locking edge portion 28 a of the adjuster body 2, the locking claw body 29 has a locking distance in which the distance from the adjuster rail substrate 10 is the shortest due to the inclination. It can be the edge portion 28b. When locking by the locking edge portion 28b is performed, the biting of the locking edge portion 28b with respect to the locking protrusion 12 of the adjuster rail 1 is made stronger than the locking by the locking edge portion 28a. Has the advantage that can be.
The direction of the adjuster body 2 (that is, which of the locking edges 28a and 29a is used) can be selected as appropriate in consideration of the degree of bending of the adjuster rail 1 and the like.

  The guide slope 12b in the locking projection 12 of the adjuster rail 1 is formed in a planar shape, but the present invention is not limited to this, and may be formed in a curved surface, for example.
