The present invention relates to a slide fastener with ventilation holes attached to openings such as sofa cushions, cushions, bed mats, etc., and even if the transverse tension acts on the slide fasteners, the fastener tape does not deform or the vent holes are deformed. An object of the present invention is to provide a slide fastener capable of maintaining a sufficient intake and exhaust function even under operating conditions.

Breathable slide fasteners of this kind form rough tissues by means of weaving between the element attachment edges of the fastener tape and the attachment attachment edges, or as shown in FIG. It has been proposed to form a plurality of small round holes (A) and (B) by punching in a fastener tape made of a knitted or knitted or synthetic resin film material.

However, the formation of the rough tissue portion by the weaving means is a rough construction by omitting the inclination, so that the strength as the fastener tape is lowered, and the nose of the rough tissue portion is displaced so that the strength of the slide fastener is insufficient and the breathability is poor. As shown in Fig. 4, the group of small round holes (A) (B) is formed in the small round holes (A) (B) group in the tension direction when the tension in the transverse direction is applied. The fastener tape also extends in the transverse direction, whereas the fastener tape shrinks in the longitudinal direction, so that the fastener tape creates corrugated wrinkles (C), and the element strings as a whole of the slide fasteners This results in a drawback of not only smooth opening and closing of the slider, but also poor appearance and insufficient breathability.

This invention can be made into the structure described in the claim of utility model registration, and can make the breathable slide fastener which does not follow the fault mentioned above.

Hereinafter, the configuration thereof will be described in the illustrated embodiment.

FIG. 1 is a plan view showing an embodiment of the slide fastener 1 individually, and the fastener tapes 4 and 5 of the left and right pair of fastener stringers 2 and 3 are knitted with light Maryas, and the elements (6) Whale settlement band (11) (12) in the middle of the attachment attachment edge (9) (10), which is a sealing portion such as the element attachment edge (7) (8) and cloth (***) to which the group is fixed Inserting the yarn 13 and 14 into the wale settlement band 11 and 12 to form a substantially square breathable 15 and 16 continuously in the longitudinal direction of the fastener tape. It is.

And the wales 17, 18, 19, and 20 located at both sides of the wale settlement bands 11 and 12 have element attachment edges 7, 8 and adherend attachment edges 9, 10. It becomes a strong wale from a wale forming a ground structure, and the insertion yarns 13 and 14 are made of a yarn that is stronger than the above-described braid knitting.

2 is an organization chart showing an example of the fastener tape 4, wherein the element attachment edges 7 and the adherend attachment edges 9 are 1-0 / 0-1 chain surface tissues 21 (22) and 1 It consists of a tricot piece (23) (24) of -2 / 1-0 and a single coat piece (25) (26) of 0 -1/4 -3, and in the Whale settlement band (11) as described above, Whales for the wale are settled, and wales 17 and 18 located on both sides of the band are inserted into the 0-0 / 1-1 / 0-0 / 4-4 / 3-3 / 4-4 tissues between them. The yarns 13 are enclosed and interlocked only with both wales 17, 18, and connect the both attachment edges 7, 9.

In the embodiment of FIG. 2, since the knitting yarns 27 and 28 of the chain knitting tissue forming the wales 17 and 18 are thicker than the other knitting yarns 29 and 30, this wale ( 17) (18) is hardened, but the thing of the same thickness as the knitting yarn 29, 30, etc. should be used by tying a plurality of strands together. The outer wales 31 of the element attachment edges 7 and the outer wales 32 of the adherends 9 to be attached are also strong wales like the wales 17 and 18.

The insertion yarn 13 may also use a twisted yarn that is several times thicker than the knitting yarns 29 and 30 (for example, 500 denier yarns), or may be bundled in plural strands.

Since the insertion yarn 13 is entrapped in the above-described tissue, the wale settlement band 11 has an insertion yarn 13 disposed across the wale settlement band 11 in a direction orthogonal to the wale, and the insertion yarn 13 As the wale settlement band 11 is divided into a substantially square shape in the longitudinal direction of the fastener tape, and each division forms the vent hole 15.

3 is another embodiment of a fastener tape, in which two strands of insertion yarns 33 and 34 are 0-0 / 1-1 / 0-0 / 1-1 / 0-0 / 4-4 / 3-3. / 4-4/3-3/4-4 and 4-4/3-3/4-4/3-3/4-4/0-0/1-1/0-0/1-1/0 It was formed of the same knitted fabric as the embodiment shown in FIG. 2 except that the chain knitted tissue was removed from the middle band of the adherent edge and the adherend attached to the tissue of 0, and located on both sides of the wales settlement band It is also the same as the embodiment of FIG. 2 that the wales 35, 36 connected by 33) 34 are stronger than the wales of the local tissue.

Since the present invention has the above-described configuration, when the transverse tension acts on the slide fastener 1, the tension is attached to the element attachment edge 7 through the insertion yarns 13 and 14, which are enclosed to form an approximately square vent hole. 8) or the adherend attachment edges 9 and 10 in the direction orthogonal to the wale, resin, and vent holes 15 and 16 do not deform in the transverse direction. The fastener tape is not deformed and distorted. Accordingly, the fastener tapes 4 and 5 do not wrinkle or deform into waveforms, and the entire slide fastener always maintains a square appearance. In addition, since the vent holes 15 and 16 do not deform, a normal intake and exhaust action is always caused.

In order to cause this action, the width of the vent holes 15 and 16 is preferably 1 mm x 2 mm to 0.5 mm x 0.5 mm or 1 mm x 1 mm, and the number of wales to be settled is selected in the range of 1 to 3 wale. It is not specifically limited.

The present invention has the above-described configuration and operation, and since the insertion yarn is disposed in the wale settlement band in the direction orthogonal to the wale, and forms a substantially square vent hole, the insertion yarn is square even if a strong lateral attraction acts on the slide fastener. As it is stretched in the direction of the side orthogonal to the wale of the zigzag, it does not deviate in the longitudinal direction of the fastener tape. As the vent hole is deformed, the fastener tape is not wrinkled or deformed. It has the effect of maintaining an orderly appearance without backing, smooth opening and closing of the slider, and even when the transverse tension is applied as described above, the vent hole hardly deforms, so that it always exhibits sufficient intake / exhaust function. It works.

In addition, fastener tape is formed with light Meriya's tissue, and the insert is protected by the tissue so that no thread or nose is pushed out. Furthermore, the Whale settlement band is divided into the insert yarn to form a continuous, substantially square aeration air force. Therefore, there is an effect that can always ensure a large ventilation area.

And because the wales located on both sides of the wale settlement band are tightly organized and the insert yarn is considerably stronger than the other knitting yarns, the fastener tape can have the required tape strength despite having a large aeration area. It is possible to maintain enough.

And wherein the wale settling band is a continuous portion of approximately square shaped vents (15, 16).
