In other words, the second engaging portion 22b formed in the elastic portion 12b of the pull-up piece is in a state of being fastened to the second engaged portion 23b of the stretched portion, and can be retracted from the unloaded tab. a position of interference. As shown in Fig. 5 and Fig. 6, the first engaging portion 22a formed on the elastic portion 12a of the pull tab 11a that is rotated can be engaged with the second engaging portion formed on the slider i〇b. By the recessed portion of 23b, the elastic member 2 can be maintained in a state of being compressed and deformed, and one of the pair of sliders can be adhered to each other and (10). Moreover, it is possible to prevent the separation of the sliders l〇a, l〇b from one of the seals. Further, the upper blade l6a is formed by linearly forming its front end and the rear end, and also forming the shape of the side edge portion in the longitudinal direction in a straight line, whereby the elastic portion 12a of the tab 1U is used. When the upper wing 16a is surrounded, the liquid-tightness is allowed to be exerted. In particular, the second engaging portion 22b of the elastic portion 12a can be engaged with the front edge 19 of the upper flap 16a, and the upper flap can be sandwiched by the side portion 26 of the elastic portion 12a! The side edge of the length direction of 6a. Further, the second engaging portion 22b formed on the elastic portion 12a of the pull tab 11a as shown in Fig. 7 can be deformed while abutting against the side edge portion of the upper flap 16a of the slider 10b. And being engaged with the second engaged portion 23b formed at the side edge portion of the upper blade 16a. Further, it is possible to prevent the slider Ua that is rotated from rotating in the reverse direction. Thus, in the state in which the pair of sliders 1a and 10b are rotated, the pair of sliders 10a and 10b are abutted and held in a close contact state by rotating one of the sliders 11a. At this time, by forming the front edge 19' of the upper blade 16a in a straight line, the I45090.doc • 20-201102014 close contact surface of the front end edge 19 of the aligned sliders 1a, i〇b can be maintained. Better composition. However, the present invention is not limited to the configuration in which the front edge 19 of the upper blade l6a is formed in a straight line as long as the front edge 19 of the pair of sliders 1a, 1b can be joined to each other, for example, Forming one of the front end edges 19 in a curved shape or the like and forming the shape of the front end edge 19 of the other end edge 19 adjacent to the one end is formed in a direction opposite to the curved shape of the one front end edge 19, and A curved shape that is fitted into a curved shape of one of the front end edges 19. Further, the shape is not limited to the shape in which the front end edge 19 is curved, and may be formed in a suitable shape such as a zigzag shape. Further, when the sliders 1 〇 a and i ob are separated from each other, the slider 1 i a can be rotated in the reverse direction, so that the first! When the engaging portion 22a is elastically deformed, the first engaging portion 23a is released from the state, and the second engaging portion 22b can be released from the second engaged portion 23b while being elastically deformed. Since the pair of sliders 10a and 10b are disposed such that the sliders of the same configuration are opposed to each other, the sliders "1" and "b" are inserted into the pair of fasteners 8, It is not necessary to separately treat the sliders 1a and 1b. Therefore, the manufacturing efficiency of the waterproof zipper can be greatly improved as compared with those described in the patent document. The sliders 10a, 10b can be pulled by the tabs 11a'nb The merging portion 22a and the second engaging portion 22b are engaged with the two sliders 〇a and 〇1 of the opposite side. According to this configuration, each of the sliders 1a, The posture of 1〇b is fastened in a stable state. Further, the second hook portion 22a is fastened to the engagement opening side of the main body 16, and the second buckle is fastened to the introduction port side of the main body 16. The engaging portion 22b, so that the second engaging portion 22a can prevent the sliders from being separated from each other in the longitudinal direction of the zipper I45090.doc • 21 · 201102014. Further, the second engaging portion 22b is fastened to the vicinity of the shaft portion 13b and is It is easy to maintain the fastening state by releasing the rotation of the buckle in the downward direction (toward the rotation in the direction of the slider separated by the engagement side). Further, since the second engaged portion 23b is formed on the introduction port side of the sliders 1a, 1b, or the width direction of the contact member, the second engagement portion 22b is formed in the width direction of the tab. Therefore, even if the second engaging portion 22b is engaged with the second engaged portion 23b, a change in the relative posture occurs between the sliders 1〇3, 1〇b and the sliders on the opponent side, i〇b. However, since the fastening is performed in the width direction, it is easy to maintain the fastening state. The reason is that when the sliders 1〇a, 1〇1) and the opposite side sliders l〇a, l〇b are pulled, At the time of the fastening, the waterproof zipper 1 having the snap-fit b is changed so as to be curved in the longitudinal direction of the chain cloth. Therefore, the fastening state in the width direction changes the length direction of the chain fabric. In addition, the waterproof chain cloth 2 may be coated with an elastomer resin or the like for the fiber material, but in this case, the rigidity of the crucible is increased only by the chain of the fiber. Therefore, a pair is performed. When the sliders 1〇a and 1〇b are combined, there is a possibility that the slider will not be affected by the straightness. And in an angled state, even in such a case, as in the present invention, since it is fastened at two places, it can be corrected to match in a suitable merging state and maintain the appropriate The second embodiment will be described with reference to Figs. 8 to 11 , and the second embodiment is constructed by covering the entire body of the pull tab except the mounting member 13 by the elastic portion 12 145090.doc • 22· 201102014. As a configuration of the first engaging portion 22a of the elastic portion 12, the second embodiment is different from the configuration of the protruding portion described in the first embodiment. Further, the second embodiment is not used in the upper flap. The configuration of the elastic member 2'' on the end side before the 16a. The other components are the same as those of the embodiment i, and the same reference numerals are used for the components used in the embodiment i, and the description of the components is omitted. In the second embodiment, as the waterproof zipper, the configuration in which the pair of sliders 10a and 10b are used will be described. As shown in Fig. 8, since the entire body of the pull tab body other than the mounting member 13 of the pull tab is covered by the elastic portion 12, the inside of the elastic portion 形成2 formed in a substantially lateral U-shape is formed. The main body of the slider (not shown) connected to the main body 16 of the slider t is housed. Therefore, the elastic portion 12 of the second embodiment can increase the rigidity of the entire elastic portion 12 as compared with the configuration of the elastic portion 12 of the embodiment. Further, when a central portion of the elastic portion 12 which is formed in a substantially lateral U-shape is provided with a handle main body (not shown), when the elastic portion 12 is hooked on the other sliding member, the elastic portion 12 is attached. It is difficult to elongate significantly, and it is difficult to hook the elastic portion 12 to the other sliding member. Therefore, the central portion of the elastic portion 12 formed in a substantially U-shaped shape may not be provided. The slider body shown. Since the pair of sliders 1a, 1b can be constructed in such a manner, when a pair of sliders 10a, 10b are separated by one of them as shown in Fig. 9, a pair of slides is shown in Fig. 10. When the pieces l〇a, l〇b are aligned with each other, and further, one of the pull tabs 1 la is rotated in such a manner as to cover the sliders 1 〇 b on the opposite side, it can be substantially 145090.doc -23-201102014 The body i6 side in the front-rear direction of the ten-membered portion of the U-shaped elastic portion 12 is in close contact with the rear end surface of the upper blade 16a of the slider 10b on the opponent side, and is maintained in a engaged state by friction. That is, as shown in Fig. 11, by elastically deforming the central portion of the elastic portion 12 provided in the rotating pull tab 11&, the elastic force of the connecting portion of the elastic portion 12 at the central portion in the width direction can be utilized elastically. The meshing port of the main body 16 is in close contact with each other, and the sliding members i 〇 a and i 〇 b are in a state of being in contact with each other and maintained in close contact with each other. At this time, the inner portion of the elastic portion 12 has a tab body therein, so that the elastic force between the end surface of the flap 16a and the inner side surface of the elastic portion 12 as the slider lb can be adjusted by adjusting the thickness of the elastic portion 12. Get the desired elasticity. Further, at this time, the front edges 19 of the upper flaps 16a of the respective sliders l〇a, l〇b are adhered to each other, but the adhesion between the front edges 19 of the upper flaps l6a is further improved. The elastic member 2' can be provided in the same manner as in the first embodiment, at least one of the front end edges 19' of the front edge 19 of the upper blade 16a. The rear end surface of the upper surface of the flap 16a of the slider 10b and the inner side surface ' of the elastic portion 12 are in a state of being tightly sealed between the pair of sliders 10a, 1 Ob, due to the rear end surface of the flap 16a on the slider 10b. The sliding frictional resistance between the inner side faces of the elastic portion 12 is large, so that the pull tab 11a hooked to the end surface of the flap 16a above the slider 10b is not easily disengaged. Therefore, it is not necessary to separately provide the second engaging portion 22b and the second engaged portion 23b. However, as shown in Fig. 11, the pull tab lib on the side of the slider 10b is placed so as not to interfere with the slider iia which is rotated. As shown in FIG. 10, the second engaging portion 22b and the second engaged portion 23b which are provided on the same slider 10b can be engaged with each other, as shown in FIG. As shown in Fig. 11, the second engaging portion 22b formed in the elastic portion 12 of the rotating pull piece 11a can be respectively engaged with the second side of the introduction port side of the flap 16a formed on the slider i〇a. The engaging portion 23b and the second engaged portion 23b formed on the introduction port side of the flap 16a on the slider 10b. By doing so, it is possible to have double safety to prevent the rotating pull tab 11a from being disengaged from the slider 10b on the opponent side.
