Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hook-and-loop fastener structure which can be easily attached to clothing such as shirts and metal mesh sheets.

[0002]

2. Description of the Related Art A hook-and-loop fastener (Velcro), which is generally known as a brand name Velcro, is used for clothing, bags, shoes, sports equipment, automobile and airplane sheets because of its simplicity of attachment and release and ease of attachment processing. Widely used for various applications such as covers.

A hook-and-loop fastener has various structures depending on a hook shape, a manufacturing method, and the like. Basically, FIGS. 7 and 8
As shown in FIG. 1, two fastener tapes 1 and 2 provided with piles (resin fibers or the like) of different shapes are arranged, and a large number of minute hook-shaped fibers 3 are arranged on one fastener tape to form a hook surface. A large number of loop-shaped fibers 4 are arranged on the other fastener tape to form a loop surface. When the two tapes 1 and 2 are brought into surface contact, the hook-shaped fibers 3 are hooked on the loop-shaped fibers 4 and maintain the state of engagement with each other. When removing the fastener, each hook-shaped fiber 3 is detached from the loop-shaped fiber 4 by pulling one tape. Note that there are various types of hooks, such as a hook-like hook (FIG. 7) having a relatively low engaging force and suitable for frequent attachment and detachment, and a mushroom type (FIG. 8) exhibiting a stronger engaging force.

[0004]

However, such a conventional surface fastener requires two different engagement structures, a hook surface and a loop surface, and male and female fasteners are respectively provided at two portions to be engaged. Tape must be installed.

[0005] Such a conventional surface fastener has no problem in maintaining good engagement. However, there is a problem that the conventional fastener tape cannot be used at all when it is desired to easily attach the fastener surface to ordinary clothing cloth. For example, a conventional hook-and-loop fastener cannot be used at all when a name plate is temporarily attached to a chest at a meeting such as a party or when it is desired to lightly tie the back of a tie to a shirt. This is because there is no fastener structure (hook or loop) to be the other side of the cloth. For this reason, when attaching a nameplate or ribbon to clothes, safety pins or clips are often used. However, pins and clips are cumbersome to install, and many people dislike using them because they hurt the fabric.

[0006] If you want to keep a nameplate or accessories (number tags, ribbons, etc.) on clothes or hats for a short time, or when you forget a tie pin and want to prevent the tie from slipping for a while, There are many cases where a simple fastener tape is required in daily life. However, since the conventional fastener tape requires a pair of male and female tapes having different structures, the application range is narrow and limited in spite of the convenience of engaging and disengaging. Such a situation is the same in other fields such as civil engineering work and industrial waste treatment. Because it is difficult to attach the other fastener tape, other members, such as nails, screws, bolts,
Adhesive tape or the like may be used. Specifically, for example, provisional fixing and holding of lightweight sheets in building exterior wall construction, and prevention of slippage of rubber sheets in a management type disposal site for industrial waste.

It is an object of the present invention to provide an easily detachable hook-and-loop fastener structure applicable to general fabric fibers such as clothes and hats, or a certain kind of mesh-structured fabric applicable to civil engineering works and the like. Is to do.

[0008]

In order to achieve the above object, a hook-and-loop fastener tape according to the present invention has a pile of a predetermined shape formed of a flexible material on at least one surface of a flexible tape material. Assuming a hook-and-loop fastener tape as a technical premise, the pile includes a main trunk that rises substantially at right angles to the tape cloth, and a plurality of branch piles branched from the main trunk, and the branch pile has a substantially linear shape. And tilted toward the tape cloth side from the base end toward the front end.

The main trunk portion has an acute-angled distal end portion that expands from the distal end toward the proximal end side, and the branch pile may have an outer diameter smaller than a general outer diameter of the main trunk portion.
The branch pile may be formed by cutting the surface of a material pile constituting the main trunk. The pile may be erected on the tape fabric by electrostatic flocking.

[0010]

The hook-and-loop fastener tape according to the present invention, by itself, can be attached to clothes or other mesh-structured fabrics. The reason is as follows.

The pile used in the present invention includes a main trunk (main pile) which rises substantially at right angles to the fastener tape material, and a plurality of branch piles branched from the main trunk. The main trunk portion needs to have a small outer diameter that can enter the gap of the mesh structure of the cloth to be applied, but the gap size of the mesh differs depending on the cloth material such as nylon cloth or silk. It is considered that the pile may have an outer diameter of about 10 to 30 denier for a general clothing material such as a blended material. Larger outer diameters may be used when applied to highly breathable hemp or cotton fabrics.
Also, mesh fabrics (including metal meshes) that are used for civil engineering work have large gap sizes, so that the outer diameter of the pile main trunk can be set relatively freely.

When the main body enters the mesh structure of clothes or the like, a branch pile branching from the main body,
Engage with the mesh structure of the fabric. Of course, the branch pile also needs to have an outer diameter dimension that allows it to enter the mesh structure of the target fabric. This is because the mesh cannot be engaged unless it is inserted into the mesh space of the fabric. When the outer diameter of the pile serving as the main trunk is sufficiently small, the outer diameter of the branch pile may be larger. However, it is easier to mold if the outer diameter of the pile serving as the main trunk is designed to be larger than that of the branch pile. This is because it is easiest to cut the surface of the main pile (cut the surface) to form a branch. It is noted that the outer diameter of the branch pile is made smaller than the outer diameter of the main trunk. For branch piles, besides cutting the main pile surface, electrostatic flocking, etc.
It can be erected on the main pile by an appropriate method.

[0013] The branch pile which is engaged with the mesh space of the cloth or the like is inclined in the direction of the tape cloth. This is for facilitating entry into the mesh voids and, conversely, for making it difficult to separate by external force. Specifically, when the pile serving as the main trunk is rising upward, the branch pile is hanging downward.
It is the same as the angle setting of the wing of an aircraft that experiences strong air resistance when traveling. With such an angle setting, the branch pile enters without resistance when entering the mesh void, and requires a forced external force by human power when leaving.
Since the entire pile is formed of a flexible material, the fastener tape can be easily removed by pulling it lightly. However, it cannot be easily removed by natural external force such as wind.

In order to make it easier to enter the fabric fibers by the mesh voids, the main trunk portion (main pile) has an acute-angled front end portion that expands from the front end to the base end side. May be provided.
In this case, it means that the outer diameter of the main trunk is somewhat large. Therefore, it is desirable that the branch pile has an outer diameter smaller than the general outer diameter of the main trunk.

The method of forming the branch pile branched from the main trunk is not limited, but as described in claim 3, it is easiest to cut and form the surface of the material pile constituting the main trunk. In this case, while moving the pile serving as the main trunk, a micro cutter is brought into contact with the pile surface at an appropriate timing to form a branch. When shaping the tip of the main body into a cone, pyramid, or other sharp shape (the tip may be rounded), adjust the cutter angle or cut the cutting speed with the moving speed of the forming pile. Give an error to the timing. Cone cutting by heat (including laser light) or water pressure may be used.

The method for erecting the pile on the fastener tape surface is not particularly limited. As described in claim 4, the tape cloth may be erected by electrostatic flocking. In the case of electrostatic flocking, the standing angle of the pile (main trunk pile) with respect to the tape cloth varies. About 50 per flocking
The other 50% of the piles are upside down or lying down when looking at the% standing. However, if the tape is not normally erected and fixed, the defective pile is peeled off by brushing the tape surface lightly. After removing the illegally stuck pile, the electrostatic flocking is performed again.
5% of piles stand in normal direction. The existence of the overturned pile and the inverted pile is the same in the normal hook-and-loop fastener pile. In short, the object of the present invention can be sufficiently achieved if the pile can be considered to be stood normally and stochastically and normally.

The pile according to the present invention is desirably made of resin fibers. However, when the pile is applied to a micro-porous mesh used for civil engineering work, a flexible low-cost metal pile such as aluminum fiber is used. May be used.

[0018]

Embodiments of the present invention will be described below with reference to the accompanying drawings. 1 to 6 show an example of a hook-and-loop fastener tape according to the present invention. As shown in the figure, this fastener tape 10 is obtained by arranging a large number of piles 12 of a predetermined shape on the surface of a flexible tape cloth 11 (for example, cloth, resin or metal sheet). The main trunk 13 is made of a flexible material (for example, resin or metal) and rises substantially at right angles to the tape cloth 11, and a plurality of branch piles 14 branched from the main trunk 13.

The main trunk portion 13 has a small outer diameter that can enter a mesh space such as clothing to be applied.
An acute-angled distal end portion 15 is formed so as to expand from the distal end toward the proximal end side so as to facilitate intrusion. On the other hand, the branch pile 14 has an outer diameter dimension smaller than the general outer diameter dimension of the main trunk section 13, has a substantially linear shape, and is inclined toward the tape cloth from the base end toward the tip. This is because the pile 12 can easily enter the mesh space such as clothing and the branch pile 14 is hooked on the mesh structure to make it difficult for the tape to be detached by an external force.

FIG. 2 shows the operation of attaching the tape 10 to the mesh structure fabric 30. As shown in FIG. 3A, the branch pile 14 has the same flexibility as the main trunk 13, so that when the branch pile 14 enters the mesh space S, it falls down to the peripheral surface of the main trunk, and does not hinder the engagement operation of the pile 12. . on the other hand,
After penetrating into the mesh, the branch pile 14 returns to the original shape that protrudes in a branch shape around the main trunk as shown in FIG. Further, as shown in FIG. 3C, when a forcible external force is applied by human power, the branch pile 14 bends upward, so that the pile 12 is disengaged from the mesh space S, and the fastener tape 10 is transferred to the fabric 3.
Can be pulled away from zero.

The branch pile 14 is, for example,
Can be formed by cutting the surface of the material pile that constitutes. FIG. 3 exemplifies a method of forming the branch pile 14. As shown in FIG. 3, the cutters 21 and 22 are moved at appropriate timing while moving the constituent material 13a of the main trunk pile in one direction (arrow X). Material pile 13
The branch 14 can be formed by peeling the surface of the pile 13a by contacting the surface of the pile 13a. The length and the forming interval of the branch 14 can be freely set depending on the transport speed of the material pile 13a and the timing at which the cutters 21 and 22 are brought into contact. The outer diameter of the branch can be determined by the contact interval (cutting depth) of the cutters 21 and 22 to the material pile 13a. Specifically, the smaller the interval between the cutters 21 and 22, the larger the outer diameter of the branch. Can be formed.

In order to form the tip of the main trunk portion 13 into a cone, a pyramid, or another sharp shape, for example, as shown in FIG. 24, the material pile 13a may be cut obliquely. When the pile is erected vertically on the tape material by electrostatic flocking, it is desirable that the cut surface on the base end side of the main trunk is vertical in order to increase the fixing strength of the pile. Therefore, in the example shown in FIG.
4 is sent out in the opposite direction to that of the example shown in FIG. 4, the base end side of the main trunk is first cut vertically by the cutter 25, and then, the other end is sharply cut by the other cutters 26 and 27 arranged obliquely. According to such a processing method, it is possible to form a pile having a perpendicular pile base end and excellent fixability to a tape material. The cutting of the material pile can be performed by heat (including laser light), water pressure, or the like, in addition to the cutter.

The pile 12 formed with the branch pile 14 and provided with a sharp end portion can be erected on the tape material 11 by, for example, electrostatic flocking. For example, as shown in FIG. 6, the tape cloth side is grounded, a voltage is applied to the pile side, the pile 12 is dropped toward the tape cloth 11, and the pile is fixed to the tape surface 11a. An adhesive is applied to the tape surface 11a.

When a pile is planted by electrostatic flocking, as described above, even if it is possible to stand about 50% by one flocking process, the other 50% of the pile is reversed. Or lying on its side. However, by brushing the tape surface, it is possible to peel off and remove defective piles that are not normally standing and fixed. Furthermore, by performing electrostatic flocking again after removing the defective pile, the number of normal-oriented piles (density) that can contribute to the attachment can be increased.

In the example shown in FIG. 6, a so-called down system in which the pile is dropped from above is employed, but an up system in which the pile is lifted from below may be used. If piles are supplied from both the upper and lower sides, piles can be planted on both sides of the tape fabric by a single flocking process (in this case, adhesive is applied to both sides of the tape fabric), so-called double-sided fabric Tape can be configured. According to such a tape configuration, articles can be engaged with each other without attaching a tape in advance. For example, when a tie is to be engaged with clothing, it is only necessary to interpose the tape fragment having an appropriate length between the tie and the clothing.

The fastener tape of the present invention can be used not only in the field of apparel but also in other fields such as civil engineering work and industrial waste treatment. For example, in a management type disposal site for industrial waste, a rubber sheet may be spread all over the dumping hole to prevent environmental pollution via groundwater. Since this rubber sheet needs to secure watertightness, it was not possible to simply hit an anchor and fix it to the ground, and the construction was conventionally complicated. In addition, since rubber sheets were laid directly on the ground, there were not a few accidents in which the buds and roots of the trees broke through the sheets, and the weight of the buried waste shifted the sheets, causing cracks and leaking wastewater underground. There was something to do.

On the other hand, if the fastener tape of the present invention is arranged on the back surface of the rubber sheet, for example, a metal sheet having a mesh structure is laid on the dump hole ground, and the rubber sheet is fixed to the metal sheet. In addition, a rubber sheet that is disadvantageous in strength can be protected by the metal sheet, and leakage of sewage can be more reliably prevented. It is not necessary to consider the water tightness of the metal sheet that supports the rubber sheet, so it can be easily fixed to the ground by placing an anchor or the like, and the rubber sheet is laid with fastener tape on the metal sheet. The construction is simple because it only requires contact.

Further, the fastener tape of the present invention can be used in a construction site and other fields, for example, for temporarily fixing a lightweight sheet in the outer wall construction of a building.

The present invention is not limited to the above embodiment. In the example shown in the drawings, the branch piles are formed symmetrically on both sides of the main trunk, but the arrangement pattern of the branches may be asymmetric. The number of branches formed may be two or three, or five or more branches may be formed. Furthermore, the method of forming the sharp tip portion of the main trunk, the branch pile, and the method of erecting the pile are shown as examples, and other methods are also possible. The mesh fabric to which the tape of the present invention can be attached includes not only woven fabric but also nonwoven fabric, felt, knit, and the like.

[0030]

As described above, according to the hook-and-loop fastener tape according to the present invention, it can be applied to general fabric fibers such as clothes and hats, or to a certain kind of mesh structure fabric applicable to civil engineering and the like. It is possible to provide a hook-and-loop fastener structure that can be easily attached and detached.
