Problems solved by technology

[0034] Therefore, for example, in the waterproof slide fastener 80 of this patent document 2, when the belt back side of the waterproof tape 82 is installed on the front side of the slide fastener installation product, when the waterproof slide fastener 80 is subjected to lateral pull, water may flow smoothly. Infiltrate along the groove formed between the water repellent strip 82 and the protruding portion 87
In addition, when the above-mentioned groove is formed in the formation region of the first stopper 84, as in the case of Patent Document 1, it looks like water is allowed to infiltrate from the groove from the user's point of view. There is also room for improvement
[0035] In addition, in the first stopper 84 of Patent Document 2, since the entire belt front side of the waterproof belt 82 is covered by the front side cover portion 86, a large amount of synthetic resin is required to form the first stopper 84. , there is also the disadvantage of increasing the manufacturing cost and reducing the flexibility of the waterproof belt 82

Embodiment 1

[0077] figure 1 It is the front view which shows the waterproof slide fastener of this Example 1, figure 2 yes figure 1 Rear view of waterproof zipper. also, image 3 yes means figure 1 An enlarged view of the main part of the first stopper of the waterproof zipper, Figure 6 yes means figure 1 An enlarged view of the main part of the second stopper of the waterproof zipper.

[0078] Such as figure 1 As shown, the waterproof slide fastener 1 of this Example 1 is attached to the opening and closing part or the opening part 6a of the slide fastener attachment product 6, such as a diving suit. This waterproof slide fastener 1 has such waterproofness that liquid such as water does not leak from the outside of the slide fastener installation product 6 to the inside of the slide fastener installation product 6 (or from the inside to the outside) from the outside of the slide fastener installation product 6 when the waterproof slide fastener 1 is closed. .

Embodiment 2

[0130] Figure 7 It is an enlarged view of main parts showing main parts of the waterproof slide fastener of the present Example 2.

[0131] In addition, in this embodiment 2 and the embodiment 3 and embodiment 4 described later, the form of the first stopper is different from the above-mentioned embodiment 1, and the form of the waterproof slide fastener is different from that of the first stopper. The external structure is the same as that of the aforementioned embodiment 1.

[0132] The first stopper 40 of the waterproof slide fastener 2 according to the second embodiment has a first stopper main body 41 and a bottom protruding from the first stopper main body 41 so as to straddle the left and right waterproof tapes 11 . The first extension part 42 . In addition, the first stopper body part 41 and the first extension part 42 each have a first half part arranged on the front side of the belt and a second half part arranged on the back side of the belt, and these first half...

Embodiment 3

[0138] Figure 8 It is a front view showing a part of the waterproof slide fastener of the present Example 3, Figure 9 It is an enlarged view of the main part of this waterproof zipper.

[0139] The first stopper 50 of the waterproof slide fastener 3 according to the third embodiment has a first stopper main body 51 and a bottom protruding from the first stopper main body 51 so as to straddle the left and right waterproof belts 11 . The first extension part 52 . In this case, a concave portion 56 is formed that is recessed from the upper bottom portion 51a of the first half and the second half of the first stopper body portion 51 toward the direction (downward) in which the first extension portion 52 protrudes. . The concave portion 56 of the first stopper main body 51 is formed by a protruding portion protruding from the cavity surface side of the mold to prevent leakage of the molding material during injection molding of the first stopper 50 .

Abstract

This waterproof slide fastener (1, 2, 3, 4) is configured so that first and second through-holes (14a, 14b) are formed at specific intervals in tape side edges of waterproof tapes (11), and so that first and second halves (15, 16) of fastener elements (12) are connected and integrated together through the first through-holes (14a). A stopper (20, 30, 40, 50, 60) has a body section (21, 31, 41, 51, 61) and an extension section (22, 32, 42, 52, 62) which extends from the body section (21, 31, 41, 51, 61). First and second halves (23, 24) of the stopper (20, 30, 40, 50, 60) are disposed so as to straddle the pair of waterproof tapes (11) and are connected and integrated together through the second through-holes (14b). As a result of this configuration, the manufacturing step of the waterproof slide fastener (1, 2, 3, 4) is simplified, and water is prevented from entering even if the slide fastener (1, 2, 3, 4) is subjected to a lateral pulling force.

Description

technical field [0001] The present invention relates to a waterproof slide fastener, in particular to a waterproof slide fastener having a stopper including a waterproof structure capable of effectively preventing liquid from entering. Background technique [0002] In the past, in order to prevent liquids such as water from entering the inside when the opening and closing parts or openings of diving suits, one-piece water boots, etc. ). [0003] Waterproof zippers usually have a pair of left and right zipper fastener chains with a row of fasteners formed on a waterproof tape including a waterproof layer, and a slider that can slide along the rows of fasteners. The opposite side edges of the waterproof tape are in close contact with each other, thereby preventing water from entering from the front side of the tape to the reverse side of the tape (or from the reverse side to the front side of the tape) through between the left and right waterproof tapes. [0004] In this wat...
