Problems solved by technology

[0022] In the waterproof top stopper 52 of the slide fastener described in Patent Document 2, the waterproof top stopper 52 having the accommodation part 53 and the insertion leg part 55 must be configured, and the structure of the waterproof top stopper 52 is a complicated structure.
In addition, if the slider 58 is not brought into contact with the waterproof front stopper 52 to cover the waterproof front stopper 52 by the slider 58, the complexly formed structural part of the waterproof front stopper 52 will be exposed, lacking the ability to function as a waterproof zipper. simplicity

Embodiment 1

[0080] The waterproof slide fastener 1 of this Example is comprised with the left and right pair of fastener stringers 8, a pair of slider 10, and the back stop which is not shown in figure. figure 1 , the illustration of the slider 10 on one side is omitted, but image 3 A pair of sliders 10a, 10b are shown in FIG. A pair of fastener stringers 8 is comprised so that each may have the fastener tape 2 and the several fastener elements 3 attached along the respective opposing side edge 6 which opposes when each fastener tape 2 is arrange|positioned in parallel.

[0081] The zipper tape 2 is composed of a tape woven or braided from a fiber material as a base material 2a, and has a waterproof material formed by covering one side or both sides of the base material 2a with an elastomer resin 2b such as natural rubber or synthetic rubber. structure. exist figure 1 A configuration example in which one side of the base material 2a is covered with the elastomer resin 2b is shown in...

Embodiment 2

[0117] use Figure 8 ~ Figure 11 It demonstrates, in Example 2, it is the structure which covered the whole handle main body except the attachment member 13 with the elastic part 12. In addition, as a structure of the 1st engaging part 22a in the elastic part 12, the structure different from the protrusion-shaped structure demonstrated in Example 1 is employ|adopted in Example 2. As shown in FIG. Moreover, in Example 2, the structure which does not use the elastic member 20 arrange|positioned at the front-end side of the upper blade 16a is adopted.

[0118] The rest of the structure is the same as that of the first embodiment, and therefore, the same component reference numerals as those used in the first embodiment are used, and descriptions of the components are omitted. In Example 2, the structure using a pair of slider 10a, 10b as the waterproof slide fastener 1 is demonstrated.

[0119] Such as Figure 8 As shown, since the elastic portion 12 covers the entire handle m...

Embodiment 3

[0127] use Figure 12 to Figure 15 The waterproof slide fastener in Example 3 is configured as a waterproof slide fastener in which the slider is brought into contact with the top stop instead of the form of the waterproof slide fastener using a pair of sliders described in Examples 1 and 2. Therefore, in Example 3, there is a characteristic in the liquid-tight structure between the top stopper and the slider.

[0128] Since the other structures are the same as those in Embodiments 1 and 2, the same component reference numerals as those used in Embodiments 1 and 2 are used, and thus descriptions related to these components are omitted. . In addition, as the abutment member described in the claims, in Embodiment 1 and Embodiment 2, one slider among a pair of sliders is configured as the abutment member, and in Embodiment 3, the front stopper is used as the abutment member. constitute.

[0129] As a structure of the elastic part 12 of the handle 11 of Example 3, the whole han...

Abstract

A waterproof slide fastener capable of securing the liquid-tightness between a pair of mutually abutting sliders (10a, 10b) by a simple configuration. When the pair of sliders (10a, 10b) having linear front end edges (19), respectively, are abutted on each other and a pull (11a) having an elastic section (12a) is so rotated as to cover the mating side slider (10b), a first engagement section (22a) formed on the elastic section (12a) is engaged with the first section to be engaged (23a) of the slider (10b) while elastically deforming. At the same time, a second engagement section (22b) formed on the elastic section (12a) is engaged with the second section to be engaged (23b) of the slider (10b). Consequently, the fitted state of the front end edges (19) of the sliders (10a, 10b) can be maintained.

Description

technical field [0001] The present invention relates to a waterproof slide fastener used for liquid-tight items such as waterproof pants, waterproof boots for underwater work, various bags, waterproof boxes, etc. represented by diving suits that have been subjected to waterproof processing or water-repellent processing. The opening and closing of the item. [0002] Moreover, in this invention, what is provided in order to abut a slider and stop sliding of a slider when sliding a slider, closing a opening and closing opening while engaging a pair of fastener element mutually is called a top stopper. Background technique [0003] The waterproof zipper is composed of a zipper tape woven or braided from a fiber material as a base material, and has an elastomer resin covering one side or both sides of the base material with natural rubber, synthetic rubber, etc. Class made of waterproof structure. As the fastener tape having a waterproof structure, it may be composed of a synth...
