Abstract

The present invention is to solve the problem that the adhesive force of the conventional fasteners early deterioration, in particular, so that the adhesion force does not decrease even after long-term use does not deteriorate the attachment state, and always maintain a solid attachment force to use semi-permanently The purpose is to provide fasteners that can be used.

In order to achieve the above object, the present invention is configured by pairing a plurality of engaging protrusions 5 having an enlarged head 5-1 with appropriate diameters and angles and attaching them to the elastic base 4 at regular intervals. It provides a fastener characterized in that.

This fastener of the present invention, when the conventional fastener is used, the constituent fibers of the nonwoven fabric 3 swells like a thread due to repeated attachment and detachment, so that the adhesive force between the hook 1 and the nonwoven fabric 3 is long and used for a long time. There is a problem that cannot be solved, without the use of such a conventional hook (1) and nonwoven fabric (3) a plurality of engaging projections (5) having an enlarged head (5-1) on one side of the elastic base (4) The combination of fasteners, which are attached at regular intervals, provides the effect that the attachment force does not deteriorate even after repeated attachment and detachment of the fasteners for a long time and always maintains a firm and constant attachment force semi-permanently. .

Description

Fasteners

The present invention relates to the improvement of the lower coupling hole, and in particular to a fastener designed to reduce the adhesion even after repeated use for a long time.

Fasteners in the form of what is now known as magic tapes are generally provided with an upper fastener 7 'and a base having a plurality of hooks 1 made of hard plastic material on the base 4', as illustrated in FIG. 4 ') is composed of a combination of the lower fastener (8') attached to the nonwoven fabric (3 ') to use the attachment, separation action between the hook (1) and the nonwoven fabric (3). In the conventional fasteners, when the upper and lower fasteners 7 'and 8' are attached to each other, the upper fastener 7 'is tightly coupled to the lower fastener 8' by holding the handle 2 and the upper fastener 7 '. The end of the hooks (1) of the hook is inserted into the non-woven fabric (3) of the lower fastener (8 ') to be engaged, and when detaching, the handle (2) of the upper fastener (7') is pulled out and the hook ( 1) are to be separated from the nonwoven fabric (3). In this way, when the upper and lower fasteners 7 'and 8' are separated, the ends of the hooks 1 are separated by pulling the nonwoven fabric 3, so that the noise is not only generated but also the nonwoven fabric is repeatedly attached and detached. The constituent fibers of (3) are swelled and swelled like a thread. When the nonwoven fabric 3 is crushed in this way, the adhesive force with the hook 1 falls, so that the hook 1 and the nonwoven fabric 3 are easily separated even with a slight external impact. Will be. This results in the original fasteners failing to function, resulting in the use of fasteners such as shoes, clothing, etc. are not allowed to use.

The present invention has been devised to solve the problems of the conventional fasteners, and in particular, even when used for a long period of time, the adhesion does not decrease so that the attachment state is not deteriorated, and further improvement is possible to maintain the durable attachment force semi-permanently. The purpose is to provide a fastener.

In order to achieve the above object, the present invention provides a fastener, comprising a pair of attachment protrusions having a predetermined diameter and an angle of enlarged head attached to an elastic base at a predetermined interval.

Hereinafter, the present invention will be described in more detail with reference to the embodiments illustrated in the accompanying drawings.

As shown in FIG. 2, the fastener according to the present invention includes a plurality of engaging protrusions 5 having enlarged heads 5-1 having appropriate diameters and angles attached to the elastic base 4 at regular intervals. It consists of a combination of the fastener 7 and the lower fastener 8 having the same configuration. Between the engaging protrusions 5 of the upper fastener 7, upper engaging holes 6-1 through which the engaging projections 5 of the lower fastener 8 can be inserted are formed, and the coupling of the lower fasteners 8 is formed. Between the protrusions 5, lower coupling holes 6-2 through which coupling protrusions 5 of the upper fastener 7 can be inserted are formed.

In operation, when the upper and lower fasteners 7 and 8 are coupled to each other, the upper fastener 7 is pressed against the lower fastener 8 and vice versa, so that the engaging projections 5 of the upper fastener 7 The expansion heads 5-1 are inserted into the lower coupling holes 6-2 of the lower fastener 8 while pushing the expansion heads 5-1 of the engaging protrusions 5 of the lower fastener 8 sideways. The enlarged heads 5-1 of the engaging protrusions 5 of the lower fastener 8 are pushed to the side of the upper fastener 7 while pushing the enlarged heads 5-1 of the engaging protrusions 5 of the upper fastener 7 to the side. It is inserted into the upper coupling holes (6-1) of the). At this time, the base 4 of the upper and lower fasteners (7) (8) provides an appropriate stretching action so that the coupling between the coupling protrusions (5) of the upper and lower fasteners (7) (8) is made without difficulty. give.

When the separation between the upper and lower fasteners (7) (8) coupled in this way, when the separation force is applied between the upper and lower fasteners (7) (8) in the opposite direction, the engaging projection (5) of the upper fastener (7) The enlarged head 5-1 of the upper part of the lower fastener 8 is separated from the lower coupling holes 6-2, and at the same time the upper head 5-1 of the engaging projection 5 of the lower fastener 8; The upper and lower fasteners 7 and 8 are simply separated while being separated from the upper coupling holes 6-1 of the fastener 7.

Figure 5 (a) (b) shows an example of assembly between the base 4 and the engaging projections 5 in the fastener according to the present invention, which is a coupling projection 5 in the hole 11 of the base (4) After inserting through the rear part of), the rear end portion 12 of the coupling protrusion 5 protruding toward the back of the base 4 can be thermally deformed to achieve assembly assembly between the base 4 and the coupling protrusions 5. have.

5 (c) shows that the adhesive protrusions 13 are applied to the rear surface of the base 4 from which the rear ends 12 of the coupling protrusions 5 protrude, thereby fixing the coupling protrusions 5 to the base 4. Show the case where you have to. The coupling protrusions 5 may be made of a material such as rubber, synthetic resin, metal, and the like, and the base 4 may be made of a material having proper elasticity, such as rubber and cloth.

The fastener of the present invention avoids the structural problems of the conventional fasteners in which the attachment force is lowered early due to the above-described configuration and action, so that attachment and detachment of the fastener is easily performed, and thus it is possible to provide a durable attachment force semi-permanently. It is to provide new useful effects.
