As shown in Fig. 4, by the state in which the pair of sliders 10a, 10b are engaged with each other, as shown by the arrow, the pull tab 11a of one of the sliders 10a (slider on the left side of the drawing) is engaged by the main body 16 The mouth side is rotated clockwise toward the introduction port side, and the elastic portion 12a of the pull tab 11a can be covered on the slider 10b on the opponent side. Fig. 4 shows an example of the configuration in which the pull tab 11a is rotated, but the pull tab 11b on the opponent side can also be rotated toward the slider 10a side. The case of rotating the pull tab 11a will be described below.

As shown in Fig. 4, when the rotary tab 11a covers the elastic portion 12a of the pull tab 11a to the slider 10b on the opposite side, the first engaging portion 22a formed on the connecting side portion 25 of the elastic portion 12a is performed on one side. The elastic deformation side is engaged with the first engaged portion 23a formed in the slider 10b. At the same time, the second engaging portion 22b formed on the side portion 26 of the elastic portion 12a is engaged with the second engaged portion 23b formed before the slider 10a and the second portion formed before the slider 10b. The engaging portion 23b.

At this time, the pull tab 11b of the slider 10b on the side of the cover tab 11a is engaged with the second engaged portion 23b by its own second engaging portion 22b, and is positioned to cover the pull tab. Below the 11a position. In other words, the second engaging portion 22b formed in the elastic portion 12b of the pull-tab 11b is in a state of being fastened to the second engaged portion 23b of the pull-tab 11b, and can be retracted from the interference with the covered pull-tab 11a. The location.

As shown in FIGS. 5 and 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 engaged portion 23b formed in the slider 10b. Concave. Thereby, the elastic member 20 can be maintained in a state of being compressed and deformed, and can be closely interposed between the pair of sliders 10a and 10b. Further, it is possible to prevent the pair of the seals from being separated from each other by the pair of sliders 10a, 10b.

Further, the upper blade 16a is formed in a straight line shape in the front end and the rear end thereof, and also has a shape in which the side edge portions in the longitudinal direction are formed linearly, whereby the elastic portion 12a of the pull piece 11a is used. When the upper flap 16a is surrounded, the liquid tightness can be largely exerted. In particular, the second engaging portion 22b of the elastic portion 12a can be engaged with the front edge 19 of the upper blade 16a, and the side edge portion 26 of the elastic portion 12a can be sandwiched by the side edge portion of the upper blade 16a in the longitudinal direction.

Further, as shown in Fig. 7, the second engaging portion 22b formed on the elastic portion 12a of the slider 11a that is rotated can be deformed while abutting against the side edge portion of the upper surface of the slider 10b 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 11a that is rotated from rotating in the reverse direction.

In this manner, the pair of sliders 10a and 10b can be brought into contact with each other by the one of the sliders 10a and 10b, and the sliders 10a and 10b can be held in close contact with each other. At this time, since the front edge 19 of the upper blade 16a is formed in a straight line, the contact faces between the front end edges 19 of the sliders 10a and 10b that are aligned can be maintained, which is a preferable configuration.

However, the present invention is not limited to the configuration in which the front edge 19 of the upper blade 16a is formed in a straight line as long as the front edge 19 of the opposing sliders 10a, 10b can be closely contacted with each other, for example, one front edge 19 is formed in a curved shape or the like, and the shape of the other front end edge 19 that is joined to the front edge 19 of the one side is formed to be opposite to the curved shape of the front end edge 19, and is fitted to one side. The curved shape of the curved shape of the front end edge 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 10a and 10b are separated from each other, the slider 11a is rotated in the reverse direction, and the first fastening portion 22a can be elastically deformed while releasing the engagement with the first engaged portion 23a. In the state, 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 10a and 10b are inserted into the pair of chain belts 8 without the need for the sliders. 10a, 10b are treated differently. Therefore, the manufacturing efficiency of the waterproof slide fastener 1 can be greatly improved as compared with those described in Patent Document 1.

The sliders 10a and 10b can be engaged with the sliders 10a and 10b on the opposite sides by the first engaging portion 22a and the second engaging portion 22b provided in the tabs 11a and 11b. According to this configuration, it is also expected that the postures of the sliders 10a and 10b are engaged in a stable state. In addition, since the first engaging portion 22a is fastened to the engagement opening side of the main body 16, and the second engaging portion 22b is engaged with the introduction opening side of the main body 16, the first engaging portion 22a can prevent slippage. The pieces are separated from each other in the length direction of the zipper. In addition, the second engaging portion 22b is engaged with the shaft portion 13b, and the rotation of the second fastening portion 22b is released in the vertical direction (toward the rotation in the direction in which the slider on the opposite side is engaged). It is easy to maintain the effect of the buckle state.

Further, since the second engaged portion 23b is formed on the introduction port side of the sliders 10a and 10b or in the width direction of the contact member, the second engagement portion 22b is formed in the width direction of the tab, so even the second portion The engaging portion 22b is engaged with the second engaged portion 23b so that a change in the relative posture occurs between the sliders 10a and 10b and the sliders 10a and 10b on the opponent side, but since the width direction is engaged, It is easy to maintain the buckle state.

The reason for this is that when the sliders 10a, 10b are engaged with the sliders of the sliders 10a, 10b on the opposite sides, the posture of the waterproof zipper 1 having the sliders 10a, 10b for fastening is used in the chain cloth. The lengthwise direction changes. Therefore, the snap-fit state in the width direction is not easily affected by the change in the longitudinal direction of the chain fabric.

Further, the waterproof chain cloth 2 may be coated with the elastomer resin 2b or the like for the fiber material, but in this case, the rigidity is increased more than the fiber-like chain cloth. Therefore, when the pair of sliders 10a and 10b are engaged, there is a possibility that the sliders are not aligned in a horizontal state due to the rigidity of the sliders, but are aligned in an angled state. Even in such a case, as in the present invention, since the fastening is performed at two places, it can be corrected to the combination in the appropriate mating state, and the suitable mating state is maintained.

Example 2

Hereinafter, description will be made with reference to Figs. 8 to 11, and the second embodiment is configured such that the entire body of the handle other than the attachment member 13 is covered by the elastic portion 12. Further, as a configuration of the first engaging portion 22a of the elastic portion 12, the second embodiment has a configuration different from that of the first embodiment as described in the first embodiment. In addition, in the second embodiment, the configuration of the elastic member 20 disposed on the front end side of the upper blade 16a is not used.

The other components are the same as those of the first embodiment, and the same reference numerals are used for the components used in the first embodiment, and the description of the components will be omitted. In the second embodiment, as the waterproof slide fastener 1, a configuration in which a pair of sliders 10a and 10b are used will be described.

As shown in Fig. 8, since the elastic body 12 covers the entire body of the pull-tab body other than the mounting member 13 of the pull-tab 11, the inside of the elastic portion 12 formed in a substantially U-shaped shape is used. A pull tab body (not shown) coupled to the main body 16 of the slider 10 is housed. Therefore, the elastic portion 12 of the second embodiment can improve the rigidity of the entire elastic portion 12 as compared with the configuration of the elastic portion 12 of the first embodiment.

Further, when a central portion of the elastic portion 12 formed in a substantially U-shaped shape is provided with a handle main body (not shown), when the elastic portion 12 is hooked on the other slider of the opposite side, 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 body of the slider is shown.

Since the pair of sliders 10a, 10b can be constructed in such a manner, when the sliders 10a, 10b are separated by one of them as shown in Fig. 9, the pair of sliders 10a, 10b are opposed to each other as shown in Fig. 10. Further, when one of the pull tabs 11a is rotated so as to cover the slider 10b on the opposite side, the body 16 side in the front-rear direction of the central portion of the elastic portion 12 formed in a substantially U-shape can be closely attached to the opponent. The side slider 10b is on the rear end surface of the flap 16a and is maintained in a snap-fit state by friction.

That is, as shown in Fig. 11, by elastically deforming the central portion of the elastic portion 12 provided on the rotating pull tab 11a, the elastic portion of the connecting portion 25 of the elastic portion 12 in the width direction can be elastically adhered. The engaging portion of the main body 16 is in a state in which one of the paired sliding members 10a, 10b abuts against each other and maintains a close contact. At this time, since the inner portion of the elastic portion 12 has the tab body therein, the elastic force between the end surface of the upper surface of the flap 16a and the inner side surface of the elastic portion 12 as the slider 10b can be obtained by adjusting the thickness of the elastic portion 12. Expected elasticity.

Further, at this time, the front end edges 19 of the upper flaps 16a of the respective sliders 10a and 10b are adhered to each other, but the adhesion between the front edges 19 of the upper flaps 16a may be further improved. The elastic member 20 is provided in the same manner as in the first embodiment, at least one of the front end edges 19 of the front end edge 19 of the flap 16a.

By 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, in a state in which the pair of sliders 10a, 10b are brought into close contact, the end surface and the elastic end of the flap 16a on the upper side of the slider 10b The sliding frictional resistance between the inner side faces of the portion 12 is large, so that the pull tab 11a hooked on the end surface of the upper flange 16a of the slider 10b is not simply 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 piece 11b on the side of the slider 10b is placed so as not to interfere with the slider 11a which is rotated. As shown in FIG. 10, the second engaging portion 22b and the second engaged portion 23b provided in the same slider 10b can be engaged.

Further, as shown in Figs. 10 and 11, the second engaging portion 22b formed in the elastic portion 12 of the rotating pull tab 11a can be engaged with the introduction port side of the flap 16a formed on the slider 10a. The second engaged portion 23b and the second engaged portion 23b formed on the inlet side of the flap 16a of the slider 10b. With such a configuration, it is possible to have double safety to prevent the rotating pull tab 11a from being detached from the slider 10b on the opponent side.

The waterproof zipper of the third embodiment is in the form of a waterproof zipper using a pair of sliders as described in the first and second embodiments, and is used in the form of an upper stop abutment slider. A waterproof zipper. Therefore, the liquid-tight configuration between the upper stopper and the slider in Embodiment 3 is characterized.

The other configurations are the same as those of the first embodiment and the second embodiment. Therefore, the same reference numerals are used for the components used in the first and second embodiments, and the description of the components will be omitted. Further, in the first embodiment and the second embodiment, the first and second embodiments of the pair of sliding members are configured as abutting members, and the third embodiment is configured to abut the upper stopper. Constructed by components.

As the configuration of the elastic portion 12 of the pull tab 11 of the third embodiment, the entire body of the pull tab other than the mounting member 13 of the pull tab 11 is covered by the elastic portion 12 in the same manner as in the second embodiment. Further, the inside of the elastic portion 12 formed in a substantially U-shaped shape is a handle main body (not shown) that is coupled to the main body 16 of the slider 10. Further, the inner side surface of the central portion of the elastic portion 12 formed in a substantially U-shaped shape can be elastically deformed so as to be abutted against the end surface of the upper stopper 4.

As shown in Fig. 12, the upper stopper 4 is attached between the pair of chain fabrics 2 in a state of being interposed between the pair of chain fabrics 2 so that the opposite side edges 6 of the pair of chain fabrics 2 are in close contact with each other. . Further, as shown in FIGS. 13 and 14, the upper stopper 4 can abut against the front end portion of the slider 10 which is slid, and the sliding of the slider 10 can be stopped.

Further, the configuration of the slider 10 is the same as that of the slider of the second embodiment.

As shown in Fig. 12 and Fig. 13, the front end surface of the upper stopper 4 on the side of the slider 10 is provided with a pair of sheet portions 4a protruding in the direction of the slider 10, and one of the front end faces of the slider 10 side is opposed to the sheet portion 4a. A linear end edge that can abut against the linear front end edge 19 of the slider 10 is formed on the upper side portion.

Further, the rear end surface on the opposite side of the slider 10 side of the upper stopper 4 is configured to be substantially transverse U when the tab 11 of the abutting slider 10 is rotated to the upper stopper 4. An end surface of the first engaging portion 22a formed by the central portion of the elastic portion 12 formed in a shape.

After the upper stopper 4, the end surface is configured as the first engaged portion 23a that the first engaging portion 22a is engaged with. A groove 4b is formed on both side surfaces of the rear end side of the upper stopper 4, and is a second engaged portion that is engaged by the second engaging portion 22b formed on the elastic portion 12 of the pull tab 11 as a rotation. . In other words, the groove 4b is configured to be in close contact with the second engaging portion 22b and to be engaged by the second engaged portion by friction.

As shown in FIG. 14 and FIG. 15, when the slider 10 is engaged with the upper stopper 4, the slider 11 is rotated toward the upper stopper 4 side, and the elastic portion 12 formed in a substantially lateral U shape is formed. When the central portion is fastened to the rear end surface of the upper stop 4, the elastic members 20 provided at the front edge of the elastic portion 12 and the slider 10 can be elastically deformed respectively, and the end edge 5 of the upper stop 4 is crimped and slipped. The front edge 19 of the piece 10 is in a liquid-tight state.

At this time, one of the end edges 5 of the upper end 4 can be inserted into the side faces of the guide post from the two introduction ports of the slider 10, and between the pair of the sheet portions 4a and the guide post. The sprocket 3 disposed between the upper stop 4 and the slider 10 is in a liquid-tight state. In the state where the slider 10 is engaged with the upper stopper 4, the upper surface of the pair of sheet portions 4a is brought into contact with the lower surface of the upper blade 16a of the slider 10, so that the pair of sheet portions 4a are brought into contact with each other. The lower side is configured to be in close contact with the upper surface of the lower blade 16b of the slider 10, and the liquid tightness between the upper stopper 4 and the slider 10 can be further improved.
