- the first engaging portion 22a formed on the elastic portion 12a of the pulling handle 11a that engages is engaged with a concave portion as the second engaged portion 23b formed on the slider 10b. Can do.
- the state in which the elastic member 20 is compressed and deformed can be maintained, and the pair of sliders 10a and 10b that are abutted can be kept in close contact with each other. Then, it is possible to prevent the pair of sliders 10a and 10b that are in close contact with each other from being separated.
- the upper wing plate 16a has a front end and a rear end formed linearly, and the shape of the side edge portion in the longitudinal direction is also formed linearly, whereby the upper wing plate 16a is formed by the elastic portion 12a of the handle 11a. It is configured so that the liquid-tightness is greatly exerted when enclosed.
- the second engaging portion 22b of the elastic portion 12a is engaged, and the side edge portion in the longitudinal direction of the upper wing plate 16a is sandwiched between the side portions 26 of the elastic portion 12a. be able to.
- the second engaging portion 22b formed on the elastic portion 12a of the pulling handle 11a that has been swung is deformed while being in contact with the side edge portion of the upper blade plate 16a of the slider 10b.
- the second engaged portion 23b formed on the side edge of the plate 16a can be engaged. Then, the pulling handle 11a that has turned can be prevented from turning in the reverse direction.
- the sliders 10a and 10b can be kept in contact with each other by rotating the one handle 11a while the sliders 10a and 10b are in contact with each other. At this time, by forming the front end edge 19 of the upper blade 16a in a straight line, a close contact surface between the front end edges 19 of the abutted sliders 10a and 10b can be maintained, which is a preferable configuration.
- the present invention is not limited to the configuration in which the front end edge 19 of the upper wing plate 16a is formed in a straight line, but in a shape that allows the front end edges 19 of the butted sliders 10a and 10b to be in close contact with each other. If there is, for example, one front end edge 19 is formed in a curved shape or the like, and the shape of the other front end edge 19 that is abutted against this one front end edge 19 is the curved shape in one front end edge 19 Can be formed in a curved shape that fits the curved shape at one front end edge 19 in the opposite direction. Further, the front end edge 19 is not limited to a curved shape, and may be formed in an appropriate shape such as a zigzag shape.
- the handle 11a When the abutted sliders 10a and 10b are separated from each other, the handle 11a is turned in the opposite direction so that the first engaging portion 22a is engaged with the first engaged portion 23a while being elastically deformed.
- the second engagement portion 22b can be released from the engagement state with the second engaged portion 23b while being elastically deformed.
- the sliders having the same configuration are simply arranged so that the shoulder sides face each other. Therefore, when the sliders 10a and 10b are inserted into the pair of fastener stringers 8, the sliders 10a and 10b It is not necessary to distinguish and handle. Therefore, the manufacturing efficiency of the waterproof slide fastener 1 can be significantly improved as compared with that of Patent Document 1.
- the sliders 10a and 10b can be engaged with the mating sliders 10a and 10b at two locations by the first engaging portion 22a and the second engaging portion 22b provided in the pulls 11a and 11b. With this configuration, it can be expected that the postures of the sliders 10a and 10b are engaged in a stable state. Further, since the first engagement portion 22a is engaged on the rear opening side of the body 16, and the second engagement portion 22b is engaged on the shoulder opening side of the body 16, the first engagement portion 22a is The sliders can be prevented from separating in the longitudinal direction of the slide fastener. The second engaging portion 22b is engaged near the shaft portion 13b, and is engaged with respect to rotation in the vertical direction to release the engagement (turning away from the slider on the engagement partner side). There is also an effect of easily maintaining the combined state.
- the second engaged portion 23b is formed on the shoulder opening side of the sliders 10a and 10b and in the width direction of the contact member, and the second engaging portion 22b is formed in the width direction of the handle.
- the waterproof fastener tape 2 may be coated with a fiber material with an elastomer resin 2b or the like, but in this case, the rigidity becomes higher than that of the fiber-only fastener tape. For this reason, when the pair of sliders 10a and 10b are matched, the sliders may be butted in an angled state rather than in the horizontal state due to the influence of rigidity. Even in such a case, since the engagement is performed at two places as in the present invention, it is possible to correct the butt in the proper butt state and maintain the proper butt state.
- Example 2 which will be described with reference to FIGS. 8 to 11, the entire handle body excluding the attachment member 13 is covered with the elastic portion 12.
- the configuration of the first engagement portion 22a in the elastic portion 12 is different from the projecting configuration described in the first embodiment. Furthermore, in the second embodiment, the elastic member 20 disposed on the front end side of the upper blade 16a is not used.
- the entire handle main body excluding the attachment member 13 of the handle 11 is covered with the elastic portion 12, so that the inside of the elastic portion 12 formed in a substantially horizontal U-shape is formed.
- a puller body (not shown) connected to the body 16 of the slider 10 is housed. Therefore, compared with the configuration of the elastic portion 12 in the first embodiment, the elastic portion 12 in the second embodiment can increase the rigidity of the entire elastic portion 12 in advance.
- a puller body (not shown) is interposed in the center of the elastic portion 12 formed in a substantially U-like shape, the elastic portion 12 is moved when the elastic portion 12 is hooked on the other slider. Since it is difficult to stretch greatly and it is difficult to hook the other slider against the elastic part 12, a puller body (not shown) is interposed in the central part of the elastic part 12 formed in a substantially U-shape. It is also possible to have a configuration that does not exist.
- the pair of sliders 10a and 10b can be configured in this way, the pair of sliders 10a and 10b is separated from the pair of sliders 10a and 10b as shown in FIG.
- the two pulling members 11a are swung so as to cover the other slider 10b, the front-rear body 16 side in the central part of the elastic portion 12 formed in a substantially horizontal U-like shape is placed on the other side.
- the slider 10b can be brought into close contact with the rear end surface of the upper blade 16a to maintain the engaged state by friction.
- the elastic force at the central part in the width direction of the connecting side part 25 of the elastic part 12 is utilized.
- the pair of sliders 10a and 10b which are in elastic contact with the rear opening of the body 16 and are in contact with each other can be kept in contact with each other.
- the desired elastic force is an elastic force between the rear end surface of the upper blade 16a of the slider 10b and the inner surface of the elastic portion 12.
- the thickness of the elastic portion 12 can be adjusted so as to be obtained.
- the elastic member 20 can be provided on at least one of the front end edges 19 of the plate 16a as in the first embodiment.
