Description

[Detailed description of the invention] This invention is a base belt-less type tightening adjustment device that is used by attaching it to each tightening adjustment part to adjust the waist circumference of pants, skirts, jumpers, etc. and the opening of a hat. It is related to.

This type of tightening adjustment tool consists of a rail to which locking bodies are fixed at intervals in the length direction of the rail, and a slider slidably fitted to the rail. However, in the conventional rail, each locking body is fixed to the cord or band by crimping at intervals (U.S. Pat. No. 2,441,377,
(Refer to Publication No. 2770024), the attachment of the locking body required crimping, which was very troublesome and resulted in poor rail manufacturing efficiency. Furthermore, the quality of the rail could not be maintained constant depending on the degree of tightening of the locking bodies and the degree of maintaining the distance. Furthermore, cords and bands become stiff due to loss of flexibility due to tightening of the locking body.
Due to this stiffness, when attached to the tightening adjustment part of pants or the like, the tightening adjustment part looks unsightly, such as stiffness and wrinkles. This tends to be particularly noticeable when the fabric is thin, and there is a problem in that the type of fabric determines whether or not to use the product, and also affects the commercial value of the product used.

The present invention was devised to solve the above-mentioned conventional problems, and its purpose is to transform the locking bodies arranged at intervals into a single flexible strip at the center of the width. By adopting a rail structure in which the connecting body is integrally connected by a connecting body and the connecting body part is sewn and fixed, the flexible connecting body part that is located at the center of the rail width direction and extends in the rail length direction. Each locking body can be stabilized and firmly attached to the surface of the object by sewing, and as long as the connecting body part and the locking body are connected as one body, any connection method may be used. The first object is to provide a tightening adjustment tool that can stabilize the locking body and stabilize the rail.

The present invention will be explained below with reference to a first embodiment shown in FIGS. 1 to 8.

In FIGS. 1 to 6, A1 is a rail, and locking bodies 2 are attached at intervals by injection or extrusion molding to a single band-shaped connecting member 1, which is a band made of woven or knitted material. Each of the locking bodies 2 is connected by a connecting body 3 that is interposed between the locking bodies 2 and extends in the length direction of the rail at the center of the width direction of the locking body 2, and also injected into the end of the connecting member. Alternatively, the slider stopper 4 and the slider insertion guide 4' are attached by extrusion molding.

The locking body 2 has two slider engagement protrusions 6, 6 on the left and right sides of the surface of the rectangular base body 5, respectively.
are provided at predetermined intervals in the length direction of the rail, a sewing groove 7 is provided at the center in the width direction, and slider guide protrusions 8,
8. Then, the locking body 2 is fixed to the connecting member 1 integrally by the adhesive force by injection or extrusion molding while penetrating the widthwise center of the base body 5, and other adjacent locking bodies 2 The distance between the slider engaging protrusions 6, 6 in the rail length direction is also maintained at the predetermined value.

Such a rail A1 can be sewn by passing the sewing thread 9 through the connecting body 3 as a sewing fixing part and hooking it into the sewing groove 7 with the slider guide protrusion 8 facing the surface of the adherend B. Can be attached.

Further, C is a slider made of synthetic resin, and a body a having a rail guide groove is provided with a movable body b that can slide in a direction orthogonal to the rail guide groove, and the movable body b is caused to move as shown in FIG. A claw (not shown) that can be engaged with the left and right slider engaging protrusions 6, 6 of the rail A1 is provided. The slider C is attached to a mounting band D provided on the adherend B.
It is attached to the rail A1 and is used by being slidably fitted in the rail guide groove.

In the above configuration, each locking body 2 is stabilized and the material to be adhered B is sewn at a portion of the flexible band-like connecting body 3 that is located at the center in the rail width direction and extends in the rail length direction. It can be firmly attached by fitting it to the surface. In addition, by fixing the locking body 2 to the band-shaped connecting member 1 that continues in the length direction of the rail by injection or extrusion molding using its strong adhesive force, the flexibility of the connecting body 3 can be maintained without impairing the flexibility of the connecting body 3. Since the rail A1 can be manufactured efficiently, productivity is extremely high.

Although each locking body 2 is connected to the locking body 2 at the widthwise central portion of the locking body 2 by the band-shaped connecting body 3, in order to further improve the stability of the rail A, the seventh
As shown in the drawings and FIG. 8, the distance between the locking bodies 2, 2 may be made as narrow as possible without impairing the flexibility of the rail A.

Next, the present invention will be explained with reference to a second embodiment shown in FIGS. 9 to 11. In the rail A2 of this tightening adjustment tool, both sides of the band-shaped connecting member 11, which is a flexible synthetic resin band, are A pair of left and right locking bodies 12, 12 are formed integrally with the connecting member 11 by injection molding or extrusion molding at intervals.

In addition, the present invention is shown in Figs. 12 to 14.
To explain with an example, the rail A3 of this tightening adjustment tool has left and right pairs having the same structure as the locking body 12 formed by injection molding or extrusion molding on both sides of the band-like connecting member 21, which is a band made of woven or knitted material. The locking bodies 22, 22 are attached at intervals, and
An engagement post 24 is formed in a through hole 23 formed in the connecting member 21 to connect each of the slider engaging protrusions 6 of the locking body 22 and the slider guiding protrusion 8, It is characterized by the strong mounting method of the left and right split type unit locking body.

In addition, the present invention is shown in FIG. 4 shown in FIGS.
To explain with an example, the rail A4 of this tightening adjustment device is made by attaching locking bodies 2 at intervals by injection or extrusion molding to a wide band-shaped connecting member 31, which is a band made of woven or knitted material. ,
Engagement struts 34 are formed in the through holes 33 bored in the connecting member 31 to connect the slider engaging projections 6 of the locking body 2 and the slider guiding projections 8, and then the connecting posts 34 of the connecting body 3 are formed. Both side parts are cut out, and the effect of preventing the locking body 6 from slipping by the engagement post 34 is further improved compared to that of the first embodiment, and the locking body is made smaller than that of the third embodiment. The rail stability is good because it is not a left-right split type.

As described above, the present invention connects each of the locking bodies of the rail to each other at the center in the width direction by a single flexible band-shaped connecting body, and the connecting body is sewn into a fixed part. While the stabilizing function of the locking body is exerted by sewing the connecting body part, the flexibility of the connecting body part is not impaired, so the rail is fitted to the surface of the adherend and is stably and firmly attached. Can be done.
