Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a line coupling fastener that is linearly coupled by entanglement of a loop and a hook portion such as a surface fastener, and particularly to clothes for dress-up dolls. The present invention relates to a line-bond fastener that can be easily used as a fastener for clothes, personal items, office supplies and the like.

[Conventional technology]

As this type of fastener, there is a surface fastener that joins surfaces to each other (for example, Japanese Patent Publication No. 35-522 and Japanese Patent Publication No. 46).
-No. 5419, No. 41-7379, No. 46-1150.

This surface fastener is composed of a support base having a large number of annular or horseshoe-shaped loops formed on the surface thereof, and a support base having a large number of hook-shaped or blistered hook-stop portions formed on the surface thereof. The support bases of both are joined by hooking the hooks on the loops, and the hooks are separated by being elastically deformed and separated from the loops.

[Problems to be solved by the invention] However, in the above-described surface fastener, since the loop or the hooking portion is projected substantially vertically in the thickness direction from the surface of the supporting base, the loop layer or the hooking portion is formed. Due to the partial layers, both supporting substrates are formed to be relatively thick. Also, when joining the two supporting substrates,
Since the thick supporting substrate is polymerized and bonded, the bonding site becomes considerably thick. Usually, the thickness of the binding site is, for example, around 4 mm.

Further, when the supporting substrate is used by being fixedly attached to another cloth or the like, the thickness of the cloth or the like is added, so that the polymerized bonding site becomes thicker.

If such a surface fastener has thick walls at the supporting base itself or at the joints between the supporting bases, it will result in an unfavorable appearance and feel, so it should not be used for products where appearance and feel are important. There is a problem that it is difficult. Also,
For example, it is not possible to adequately answer the use of products requiring fineness, such as clothes for dress-up dolls.

Therefore, the present invention has been made in order to solve the above-mentioned problems, and an object of the present invention is to make a linear connection at a side end of a support base between a loop and a clasp that are coupled to each other. Another object of the present invention is to provide a line-bonding fastener that can reduce the thickness of the support base itself and the connecting portion between the support bases.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention provides that a supporting base having a large number of loops and a supporting base having a large number of hooking portions are coupled by hooking the hooking portions on the loops. Is a fastener that is separated by being elastically deformed to be disengaged from a loop, and the plurality of loops are projected from an end edge of the support base to an outer side substantially along a surface direction of the support base. Formed,
The large number of hooked portions are wire-bonding fasteners having a structure formed so as to project outward from the edge of the supporting base body substantially along the surface direction of the supporting base body.

[Action]

When connecting the wire-bonding fasteners having the above-described structure, a large number of loops of one supporting base and a large number of hooked portions of the other supporting base are brought into contact with each other mainly from the side end direction of both supporting bases. Due to the contact between the two, the loop and the hook portion are caught with each other, resisting separation, and both supporting bases are joined.

In such a line-bonded state, both supporting bases are not superposed on each other and are positioned substantially in the same plane. Therefore, the connecting portion is as thin as the thickness of both supporting bases, and the connecting portion of both supporting bases can be thinned.

Further, when separating the wire-bonded fastener, the support bases are separated from each other, but when the separation force between the loops and the clasps which are caught in each other is further strengthened in an attempt to separate the support bases from each other, The hooked portion is deformed at a portion between the locking point with the loop and the base point of the loop. Then, the angle formed by the loop and the hooking portion is opened, and when the angle is equal to or larger than the engagement / disengagement limit angle, the loop slips on the hooking portion to release the catching, and both supporting bases are separated.
On the other hand, when the engagement between the loop and the clasp is released, the deformed clasp returns to its original state due to its elasticity.

〔Example〕

FIG. 1 is a partial perspective view showing a wire coupling fastener according to an embodiment of the present invention.

One of the support bases 1 (on the upper right side in the drawing) is formed into a sheet shape by a flexible cloth knitted and woven, for example, and has a large number of substantially horseshoe-shaped loops 1a at the longitudinal edges. The large number of loops 1a are flexible, and are formed densely by projecting from the edge of the supporting base 1 to the outside along the supporting base surface direction.
The multiple loops 1a are formed by converging a plurality of synthetic fiber (for example, nylon) filaments having a diameter of about 10 to 20d along the longitudinal direction of the edge of the support base 1 simultaneously with the weaving and weaving of the support base 1. It is formed by weaving in a zigzag pattern. In the thus-formed one, the bundle of gently-converged loops 1a extends continuously on the edge of the support base 1.

The other support base 2 (on the left front side in the drawing) is formed into a sheet shape by, for example, a flexible cloth knitted and woven, and has a large number of hook-shaped hook stoppers 2a at the longitudinal edges. The large number of hooking portions 2a are elastically deformable, and are formed by continuously projecting outward from the edge of the supporting base 2 along the supporting base surface direction. The large number of hook-shaped hook-stop portions 2a are formed as follows.
First, a filament of synthetic fiber (for example, nylon) having a diameter of several hundred to several thousand d is knitted in a zigzag shape along the longitudinal direction of the edge of the other supporting base 2 at the same time as the weaving of the other supporting base 2. A large number of hooking portion forming loops are formed on the edge of the supporting base 2. Next, these loops for forming a hooking portion are stabilized by heating and the like. After that, a part of the hook-stop forming loops on the free end side is cut to form a large number of hook-shaped hook-stops 2a.

Here, in the wire-bonding fastener of the present invention, the connection and separation of the one support base 1 and the other support base 2 must be possible to be reversed. For this,
Both of the supporting bases 1 and 2 are resin-coated after the above-mentioned processing steps, and the shape of the supporting bases 1 and 2 and the supporting bases 1 and 2 of the loop 1a and the clasp 2a are formed by the resin coating. The support at is stabilized.

Next, the operation of this embodiment will be described.

When connecting the wire-bonding fasteners, one support base 1
Multiple loops 1a and multiple hooking portions of the other support base 2
2a and 2a are brought into contact with each other from the substantially side end directions of both supporting bases 1 and 2. Due to the contact between the two, the loop 1a and the hooked portion 2a are caught with each other, and resistance against separation is exhibited, and the two supporting bases 1 and 2 are linearly coupled at the edges of both supporting bases. In such a bonded state, both support bases 1 and 2 are positioned in substantially the same plane without being polymerized with each other. Therefore, the bonding portion has a thickness that is approximately the same as or thinner than the thickness of the supporting bases 1 and 2, and the bonding portions of the supporting bases 1 and 2 can be thinned.

When separating the wire-bonding fastener, the supporting bases 1 and 2 are separated from each other, but the loops 1a that are caught by each other are trying to separate from each other.
When the separation force between the hook and the hooking portion 2a becomes stronger, the hooking portion 2a is deformed at a portion between the locking point with the loop 1a and the base point of the loop 1a. Then, the angle formed by the loop 1a and the hooking portion 2a is opened, and when this becomes equal to or larger than the engagement / disengagement limit angle, the loop 1a slips the hooking portion 2a to release the catch,
Both supporting substrates 1 and 2 are separated. On the other hand, when the loop 1a is disengaged from the hook stopper 2a, the deformed hook stopper 2a returns to its original state due to its elasticity.

As described above, the present invention has been specifically described based on the embodiments. However, it goes without saying that the present invention is not limited to the embodiments described above, and various modifications can be made without departing from the scope of the invention. Nor.

For example, the support bases 1 and 2 are not limited to knitted fabrics, but may be non-woven fabrics or synthetic resin support bases. In this case, a loop 1 on such a supporting substrate 1, 2
It is possible to plant or bond the a and the clasp 2a, respectively. Further, when the support base 1 having the hooking portion 2a is formed of the synthetic resin support base, the hooking portion 2a and the support base 2 are simultaneously integrated by punching or injection molding the synthetic resin support base. It may be formed in.

Further, the loops 1a and the hooking portions 2a of the support bases 1 and 2 are not limited to the synthetic fibers as in the embodiment, but may be formed of metal filaments, for example.

Further, the loop 1a and the hooking portion 2a are not limited to those protruding in the side end direction from the end edge surfaces of the support bases 1 and 2 as in the embodiment, and may be provided near the end edges of the support bases 1 and 2. It may be projected from the surface of the supporting base substantially along the surface of the supporting base.

Further, in addition to the horseshoe shape of the embodiment, the shape of the loop 1a may be an annular shape or a semi-circular shape, and the shape of the hook 2a may be a hook shape as in the embodiment, or a mushroom-shaped expansion. It is possible to make them head-shaped, etc.
