Thereby, the first pull tab 126 is connected to the first main body 122 via the first connecting portion 124, and can rotate in the length direction (that is, the direction perpendicular to the axial direction of the mounting rod 124c). However, the present invention does not limit the specific structure and connection manner of the first slider 120 (including the first body 122, the first connecting portion 124, and the first pull tab 126), which can be adjusted according to requirements.

Similarly, the second slider 130 includes a second body 132, a second connecting portion 134 formed on the second body 132, and a second pull tab 136 connected to the second body 132 via the second connecting portion 134. Furthermore, the second body 132 includes an upper wing plate 132a, a lower wing plate 132b, and a connecting column 132c connecting the upper wing plate 132a and the lower wing plate 132b. The space between the upper wing plate 132a and the lower wing plate 132b is used for Then, the fastener element 114 (shown in FIG. 1) on the zipper fastener tape 110 is passed to open and close the fastener element 114. Furthermore, the second connecting portion 134 is a mounting ring formed on the upper wing plate 132a of the second main body 132 and having a through hole 134a, and the second pull tab 136 is provided with an opening at one end and on one side of the opening A connecting rod 136a is formed, according to which the second pull tab 136 is arranged on the mounting ring as the second connecting portion 134 in such a way that the connecting rod 136a passes through the through hole 134a. Thereby, the second pull tab 136 is connected to the second main body 132 via the second connecting portion 134, and can rotate in the length direction (that is, the direction perpendicular to the axial direction of the connecting rod 136a). However, the present invention does not limit the specific structure and connection manner of the second slider 130 (including the second body 132, the second connecting portion 134, and the second pull tab 136), which can be adjusted according to requirements.

In this embodiment, when the first slider 120 is provided on the upper side of the zipper 100 as the upper slider, and the second slider 130 is provided on the lower side of the zipper 100 as the lower slider, the first body The rear end of the first body 122 and the rear end of the second body 132 are opposite to each other, and when the first slider 120 and the second slider 130 are aligned with each other during the movement of the zipper fastener tape 110, the rear end of the first body 122 And the rear end of the second body 132 can lean against each other.

Here, the first slider 120 further includes an elastic member 128 (shown in FIG. 2) disposed between the first connecting portion 124 and the first pull tab 126. The elastic member 128 passes through the mounting rod 124c, and is leaned against and connected to one of the side walls of the accommodating groove 124a (for example, the side wall on the right side of the accommodating groove 124a in FIG. 4) and one side of the first pull tab 126 ( For example, between the concave portion on the left side of the first pull tab 126 in FIG. 4), the elastic member 128 applies force to the first pull tab 126, so that the first pull tab 126 automatically moves toward the rear end of the first body 122 (ie The lower side of the zipper 100) falls over. That is, the first pull tab 126 can be rotated in the length direction (that is, the direction perpendicular to the axial direction of the mounting rod 124c) by the user's operation to thereby drive the first body 122, and can also be maintained when no user operation is performed. In the fixed state, the fixed state is a state where the first pull tab 126 is tilted toward the rear end of the first body 122 (ie, the lower side of the zipper 100).

On the other hand, the diameter of the connecting rod 136a of the second pull tab 136 and the diameter of the through hole 134a of the second connecting portion 134 are set to be approximately the same, so the second pull tab 136 and the second connecting portion 134 are tight to each other. Match (tight fit). That is, the second pull tab 136 can be rotated in the length direction (that is, the direction perpendicular to the axial direction of the connecting rod 136a) by the user's operation to thereby drive the second body 132, and can also be maintained when no user operation is performed. In the fixed state, the fixed state is, for example, a state in which the second pull tab 136 is tilted toward the rear end of the second body 132 (ie, the upper side of the zipper 100).

In this way, in a state where the first body 122 and the second body 132 lean against each other with their respective rear ends, and the second pull tab 136 is tilted toward the rear end of the second body 132 (that is, the upper side of the zipper 100), the first The pull tab 126 tilts toward the rear end of the first body 122 (ie, the lower side of the zipper 100) and covers and fixes the second connecting portion 134 and the second pull tab 136, thereby hiding the second connecting portion 134 and the second pull tab 136 On the inner side of the first pull tab 126 (as shown in Figures 3 to 5).

FIG. 6 is a perspective view of the first pull tab 126 of FIG. 2. 3 to 6, in this embodiment, the inner side of the first pull tab 126 is provided with a concave portion, the concave portion includes a first concave portion 126b corresponding to the second connecting portion 134 and corresponding to the second pull tab 136 The second recess 126c, whereby when the first pull tab 126 falls to the rear end of the first main body 122 (that is, the lower side of the zipper 100) and covers and fixes the second connecting portion 134 and the second pull tab 136, A pull tab 126 engages the second connecting portion 134 and the second pull tab 136 with a recess (including the first recess 126 b and the second recess 126 c ). The shape of the first recess 126b is different from the shape of the second recess 126c, and the depth of the first recess 126b is different from the depth of the second recess 126c. That is, because the second connecting portion 134 is a mounting ring formed on the second body 132 and having a through hole 134a, and the second pull tab 136 is a sheet-like structure provided on the second connecting portion 134, the second connecting portion 134 The height of is greater than the height (ie thickness) of the second pull tab 136, and the width of the second connecting portion 134 is less than the width of the second pull tab 136. Here, preferably, the depth of the first concave portion 126b corresponding to the second connecting portion 134 is greater than the depth of the second concave portion 126c corresponding to the second pull tab 136, and corresponds to the first concave portion 126b of the second connecting portion 134 The width of is smaller than the width of the second recess 126c corresponding to the second pull tab 136. That is, the shape and size (such as depth) of the first concave portion 126 b correspond to the second connecting portion 134, and the shape and size (such as depth) of the second concave portion 126 c correspond to the second pull tab 136.

In this way, by providing the first recess 126b and the second recess 126c with corresponding shapes and sizes, the first pull tab 126 can cover the second connecting portion 134 and the second pull tab 136 with different shapes and sizes. That is, in the case where the first pull tab 126 is fitted with the second connecting portion 134 and the second pull tab 136 with recesses (including the first recess 126b and the second recess 126c), the first pull tab 126 appears when viewed horizontally Roughly level. In this way, the first pull tab 126 will not float on the second pull tab 136 and the second connecting portion 134. In addition, the concave portion formed by the first concave portion 126b and the second concave portion 126c is recessed inward from the inner surface of the first pull tab 126, but does not penetrate the first pull tab 126. Therefore, the first pull tab 126 faces the first body 122. When the rear end (that is, the lower side of the zipper 100) is tilted and covers and fixes the second connecting portion 134 and the second pull tab 136, the second connecting portion 134 and the second pull tab 136 are completely hidden in the first pull tab 126 The outer side of the first pull tab 126 remains flat and completely shields the second connecting portion 134 and the second pull tab 136.

Furthermore, as shown in FIGS. 5 and 6, the first pull tab 126 has a side wall 126 d surrounding the recess (including the first recess 126 b and the second recess 126 c ). The side wall 126d is a relatively high part of the outer periphery of the concave portion (including the first concave portion 126b and the second concave portion 126c), and can be provided on a part or the entire outer periphery of the concave portion according to requirements. When the first pull tab 126 is tilted toward the rear end of the first body 122 (that is, the lower side of the zipper 100) and covers and fixes the second connecting portion 134 and the second pull tab 136, the side wall 126d surrounds the second connecting portion 134 And the outer side of the second pull tab 136, so when viewed horizontally, the side wall 126d partially overlaps the second connecting portion 134 and the second pull tab 136, and when viewed from above, the second connecting portion 134 and the second pull tab 136 are hidden On the inner side of the first pull tab 126. That is, the range of the first pull tab 126 on the plane is larger than the range of the second connection portion 134 and the second pull tab 136 on the plane. Therefore, when viewed from above, the first pull tab 126 and the second connection portion 134 and the second The pull tab 136 completely overlaps.

With the above structure, the first pull tab 126 covers and fixes the entire second connecting portion 134 and the second pull tab 136, and the second connecting portion 134 and the second pull tab 136 can be hidden inside the first pull tab 126. That is, when the concave portion does not penetrate the first handle 126, the second connecting portion 134 and the second handle 136 can be completely hidden inside the first handle 126, but the first handle is penetrated in the concave portion In the case of a part of 126, the second connecting portion 134 and the second handle 136 can also be substantially hidden inside the first handle 126. In addition, the position of the first pull tab 126 in the lateral direction is restricted by the side wall 126d, so the side wall 126d/concave can prevent the first pull tab 126 from shaking in the lateral direction.

It can be seen from this that when the first body 122 and the second body 132 are leaning against each other with their respective rear ends, and the second pull tab 136 is tilted toward the rear end of the second body 132 (that is, the upper side of the zipper 100), The first pull tab 126 is automatically tilted toward the rear end of the first body 122 (ie, the lower side of the zipper 100) through the force of the elastic member 128, so that the first concave portion 126b and the second concave portion 126c are engaged with the second connecting portion 134 and the second pull tab 136, and the first pull tab 126 covers and fixes the second connecting portion 134 and the second pull tab 136. In this way, when the first slider 120 and the second slider 130 are arranged side by side and no user operation is performed, the first pull tab 126 can smoothly cover and fix the second pull tab 136 and the second connecting portion 134, and The second pull tab 136 is hidden inside the first pull tab 126, thereby reducing the possibility of shaking the first pull tab 126 and the second pull tab 136.

Furthermore, since the second pull tab 136 and the second connecting portion 134 are tightly fitted with each other, and the second pull tab 136 is tilted toward the rear end of the second body 132 (that is, the upper side of the zipper 100), the second pull tab 136 is buckled and fixed by the second recess 126c of the first pull tab 126. Therefore, the second pull tab 136 is pressed by the first pull tab 126 without the user's operation, and will not easily shake. In addition, the first pull tab 126 automatically falls toward the rear end of the first body 122 (that is, the lower side of the zipper 100) due to the force of the elastic member 128, and the first pull tab 126 passes through the first recess 126b and the second The concave portion 126c is buckled and fixed on the second connecting portion 134 and the second pull tab 136, so that the tilting direction of the first pull tab 126 (toward the lower side of the zipper 100) and the tilting direction of the second pull tab 136 (that is, the direction of the zipper 100) The upper side) is different. Therefore, the first pull tab 126 receives the force of the elastic member 128 and fits with the second connecting portion 134 and the second pull tab 136 without the user's operation, so that it will not easily shake .

The above description is only one of the embodiments of the present invention. For example, in other possible modifications, the recesses provided on the inner surface of the first pull tab 126 are not limited to correspond to the second connecting portion 134 and the second pull tab 136 As long as the first pull tab 126 can cover and fix the second pull tab 136 and the second connecting portion 134, the main purpose of the invention can be achieved. In addition, the first pull tab 126 is not limited to automatically fall to the rear end of the first body 122 (that is, the lower side of the zipper 100) through the force of the elastic member 128, and may be tightly fitted like the second pull tab 136. The method of attaching the rod 124c maintains the state of falling toward the rear end of the first body 122 (that is, the lower side of the zipper 100). Accordingly, the above-mentioned components of the zipper 100 can be adjusted in specific structure and connection mode according to requirements, and the present invention is not limited thereto.

In summary, in the zipper provided by the present invention, in a state where the first body and the second body are leaning against each other, and the second pull tab is tilted toward the rear end of the second body (that is, the upper side of the zipper), The first pull tab is tilted toward the rear end of the first body (that is, the lower side of the zipper), and is buckled on the second pull tab and the second connecting part with a recess provided on the inner side of the first pull tab, thereby covering And fix the second connecting part and the second pull tab. In this way, compared to the prior art in which only the upper pull tab and the lower pull tab are fitted and fixed to each other, the first pull tab as the upper pull tab covers and fixes the second pull tab as the lower pull tab and is connected to the second pull tab The second connecting portion of the first pull tab can smoothly cover the second pull tab and the second connecting portion in a substantially horizontal manner, and the second pull tab is almost completely hidden inside the first pull tab, thereby lowering The first pull tab and the second pull tab may shake. Accordingly, the slide fastener of the present invention can have good stability.
