Abstract

The utility model relates to a wind-proof waterproof zipper which is composed of a waterproof fabric base capable of being split into two parts, an elastic waterproof (strip) band and a row of buckle teeth fixed on side edges and combined with a pull head. The buckle teeth in an integral layered structure shaping by heating are comprise an upper and a lower sheets for the buckle teeth, two columns and a certain gap between the two sheets; the two columns are respectively fixed on the waterproof fabric base and the elastic waterproof band. The utility model has the advantages of wind tight and waterproof performances on a bond position, can be widely used on raincoats, insulated cold wear and field tents, and expands the working range of the zipper.

Description

The wind and water preventing slide fastener

The utility model relates to a kind of wind and water preventing slide fastener.

The slide fastener that has had the drawing effect is to fix row on two the fabricbase side respectively and buckle tooth can being listed as to be divided into, and makes it can make things convenient for folding by one in conjunction with pull head, designs ingeniously, easy to use, is widely used.But wind coat, raincoat, diving suit and the various windproof and rain proof cover used in wind and rain weather or many occasions, as use common slide fastener, the space of its binding site lets in air, oozes rain, has obviously limited its scope of application and effect.

The purpose of this utility model is to overcome above shortcoming, provide a kind of at the binding site place also stuffy, fluid-tight wind and water preventing slide fastener.

The utility model is to improve effectively on the basis of existing slide fastener, be about to existing constant substantially in conjunction with the profile of pull head and plastics button tooth, and the button tooth of one of the key position of engagement is specifically designed as a layered structure that two columns and a fixed gap arranged therebetween, change former fabricbase into the waterproof fabricbase again, and be with to the direction of engagement elastic water-proof of certain width (bar) that extends fixedly again, two columns in the above-mentioned button tooth then are separately fixed on above-mentioned waterproof fabricbase and the elastic water-proof band position and form, make the gap location of binding site lay the elastic water-proof band and keep certain pressure force, thereby realize that effectively sealing obtains stuffy waterproof effect.

Provide specific embodiment of the utility model in detail below in conjunction with accompanying drawing.

Fig. 1. junction schematic diagram after the utility model drawing;

Fig. 2. junction surface A-A cut-away view;

Fig. 3. single implant component schematic diagram of only detaining;

Fig. 4. button tooth A '-A ' cut-away view.

Wherein: 1. waterproof fabricbase, 2. button tooth, 3. elastic water-proof (bar) band, 4. column, 5. button tooth last slice, 6. sheet under the button tooth.

As shown in Figure 1, the utility model is formed in conjunction with pull head (summary) four parts by detaining tooth 2, waterproof fabricbase 1, elastic water-proof band 3 and having.Play two row button teeth 2 of engagement, it is the layered structure that two columns 4 and a fixed gap are arranged therebetween, as shown in Figure 3 and Figure 4, the sheet interlayer of promptly detaining sheet 6 under tooth last slice 5 and the button tooth has two short pillar type columns 4, is the integrative-structure of making by thermoplastic shaping technology with plastics.The same with common slide fastener, in order to prevent on fore-and-aft direction, to throw off after the two row buttons tooth drawings, button tooth last slice 5 and detain that sheet 6 is not just relative under the tooth, but littlely have translation to stagger.Above-mentioned column 4 is separately fixed on fabricbase 1 and the elastic water-proof band 3.The space yardstick between upper and lower of the button tooth of button tooth and the thickness of waterproof fabricbase 1 and elastic water-proof band 3 are suitable.During drawing, elastic water-proof band 3 enters another row mutually and buckles the tooth space, under the fastening power effect of button tooth, makes two row elastic water-proof band junctions keep certain pressure force, thereby plays the effect of wind and water preventing.This water blocking tape 3 comes down to waterproof fabricbase 1 extends certain width on the drawing direction extension thing, and its width is to exceed with the ventilative permeable gap of making the zipper joint position up, and structural representation is shown in cuing open when Fig. 2 is joint.Therefore, consider technologic simplification, above-mentioned waterproof fabricbase 1 and elastic water-proof band 3 also can be selected same material for use, and both are into a single integrated structure.Usually waterproof fabricbase 1 should select for use strike-through cloth or waterproof cloth to make, and elastic water-proof band 3 can select for use strike-through cloth, rubber strip and soft plastic cloth etc. to make.

In sum, the utility model can be widely used in aspects such as raincoat, insulated cold wear and open-air tent, realizes effectively stuffy, waterproof effect, has expanded the scope of application of existing slide fastener greatly.
