Technical Field
The present invention relates to a slide fastener, and more particularly, to a double-way slide fastener (two-way separator) using two sliders.
Background
A conventional slide fastener generally includes a pair of fastener stringers (fastener stringer) each having a long fastener tape (fastener tape) and a plurality of elements (elements) arranged on the fastener tape, and a slider (slider) installed on the fastener stringers so as to open and close the elements by sliding, and a pull tab (tab pull) may be further provided on the slider according to a requirement, so that a user can drive the slider to slide on the fastener chain by the pull tab. The double-split zipper is characterized in that two sliders are arranged on a pair of zipper tooth chain belts, and the two sliders can respectively open and close the zipper teeth from two opposite sides of the zipper tooth chain belts.
For example, patent document 1 discloses a double-end slide fastener in which two sliders are provided on a pair of fastener stringers. Each of the two sliders has a body and pull tabs connected by corresponding pull tab connecting portions. Further, in a state where the two main bodies are peeled from each other, the two tabs are tilted in the same direction (for example, the lower side of the slide fastener) and stacked. Therefore, a user can pull one of the pull tabs according to requirements to drive the corresponding pull head to move in the length direction of the zipper fastener chain belt so as to open and close the zipper teeth.
In order to prevent the tab from rattling at the tab connecting portion, patent document 1 discloses providing an opening in the upper tab and a protrusion in the lower tab, whereby the upper tab is fitted to the protrusion through the opening and the lower tab is fixed in a state in which the two bodies are pressed against each other. In this way, the positions of the upper tab and the lower tab can be restricted in a state where the two main bodies are pressed against each other.

Problems to be solved by the invention
In patent document 1, although the upper tab and the lower tab are fixed to each other by the opening being fitted to the protrusion, the upper tab comes to rest on the tab attaching portion of the lower body, causing the upper tab to float on the lower tab attaching portion, that is, the upper tab and the lower tab may be entirely shaken even if the upper tab and the lower tab are fixed to each other.
Means for solving the problems
The invention provides a zipper, which comprises a pair of zipper tooth chain belts, a first slider and a second slider. Each of the fastener stringers has a plurality of elements arranged in a longitudinal direction. The first slider is provided on the fastener element chain so as to be capable of opening and closing the fastener elements, and includes a first body, a first connecting portion formed on the first body, and a first pull-tab connected to the first body via the first connecting portion. The second slider is provided on the fastener element chain so as to be capable of opening and closing the fastener elements, and includes a second body, a second connecting portion formed on the second body, and a second pull-tab connected to the second body via the second connecting portion. The rear end of the first body and the rear end of the second body are opposite to each other, and the first pull-tab is tilted toward the rear end of the first body and covers and fixes the second connecting portion and the second pull-tab in a state in which the first body and the second body are pressed against each other and the second pull-tab is tilted toward the rear end of the second body.
In an embodiment of the present invention, a concave portion is provided inside the first tab, and the second connection portion and the second tab are fitted into the concave portion in a case where the first tab is tilted toward the rear end of the first body and covers and fixes the second connection portion and the second tab.
In an embodiment of the present invention, the recess includes a first recess corresponding to the second connection portion and a second recess corresponding to the second pull tab, a shape of the first recess is different from a shape of the second recess, and a depth of the first recess is different from a depth of the second recess.
In an embodiment of the present invention, in a case where the first tab is fitted with the second connecting portion and the second tab in the recess, the first tab appears substantially horizontal when viewed in a lateral direction.
In an embodiment of the present invention, the first pull-tab has a side wall surrounding the concave portion, the side wall surrounds an outer side of the second connecting portion and the second pull-tab when the first pull-tab is tilted toward the rear end of the first body and covers and fixes the second connecting portion and the second pull-tab, the side wall partially overlaps the second connecting portion and the second pull-tab when viewed in a lateral direction, and the second connecting portion and the second pull-tab are hidden inside the first pull-tab when viewed in a plan view.
In an embodiment of the present invention, the concave portion does not penetrate through the first pull-tab, and when the first pull-tab is tilted toward the rear end of the first body and covers and fixes the second connecting portion and the second pull-tab, the second connecting portion and the second pull-tab are completely hidden inside the first pull-tab in a plan view.
In an embodiment of the present invention, the first slider further includes an elastic member disposed between the first connecting portion and the first pull-tab, and the elastic member applies a force to the first pull-tab to cause the first pull-tab to automatically tilt toward the rear end of the first body.
ADVANTAGEOUS EFFECTS OF INVENTION
As described above, in the slide fastener according to the present invention, the first tab is tilted toward the rear end of the first body (i.e., toward the lower side of the slide fastener) and covers and fixes the second connecting portion and the second tab in a state in which the first body and the second body are in contact with each other and the second tab is tilted toward the rear end of the second body (i.e., toward the upper side of the slide fastener). In this way, compared to the conventional technique in which only the upper tab and the lower tab are fitted and fixed to each other, the first tab as the upper tab covers and fixes the second connecting portion to which the second tab as the lower tab and the second tab are connected, thereby reducing the possibility of the first tab and the second tab shaking. Accordingly, the zipper of the present invention can have good stability.

Detailed Description
FIG. 1 is a schematic view of a zipper 100 according to one embodiment of the present invention. Referring to fig. 1, in the present embodiment, a slide fastener 100 includes a pair of fastener stringers 110, a first slider 120, and a second slider 130. The fastener stringers 110 each have a long fastener tape 112 extending in a longitudinal direction (i.e., a longitudinal direction in fig. 1) and a plurality of fastener elements 114 arranged on the fastener tape 112 in the longitudinal direction. The first slider 120 is provided on the fastener stringer 110 and can open and close the fastener element 114. Similarly, the second slider 130 is provided on the fastener stringer 110 so as to be capable of opening and closing the fastener elements 114. In this manner, the slide fastener 100 is a so-called "double-end slide fastener", that is, the first slider 120 and the second slider 130 are provided on the pair of fastener stringers 110, and the first slider 120 and the second slider 130 can open and close the fastener elements 114 from both sides of the fastener stringers 110.
Further, when the slide fastener 100 is applied to a cloth (a jacket or the like), the first slider 120 is provided as an upper slider on the upper side of the slide fastener 100, and the second slider 130 is provided as a lower slider on the lower side of the slide fastener 100. In this way, when the first slider 120 moves upward in the longitudinal direction, the element 114 provided on the upper side of the first slider 120 can be closed, and when the first slider 120 moves downward in the longitudinal direction, the element 114 provided on the upper side of the first slider 120 can be opened. On the other hand, when the second slider 130 moves upward in the longitudinal direction, the element 114 provided on the lower side of the second slider 130 can be opened, and when the second slider 130 moves downward in the longitudinal direction, the element 114 provided on the lower side of the second slider 130 can be closed. With regard to the basic operation of the "double-opening zipper", reference is made to the prior art and the invention is not limited thereto.
Fig. 2 is an exploded view of the first slider 120 and the second slider 130 of fig. 1. Fig. 3 is a perspective view of the first slider 120 and the second slider 130 of fig. 2. Fig. 4 is an operational schematic view of the first slider 120 and the second slider 130 of fig. 2. Fig. 5 is a side view of the first slider 120 and the second slider 130 of fig. 2. Here, although fig. 1 to 5 show the first slider 120 and the second slider 130 as being arranged side by side with each other, the first slider 120 and the second slider 130 may be moved on the pair of fastener stringers 110 to be separated from each other as needed. The mounting structure and the relative relationship of the first slider 120 and the second slider 130 according to the present embodiment will be collectively described with reference to fig. 1 to 5.
In the present embodiment, the first slider 120 includes a first body 122, a first connection portion 124 formed at the first body 122, and a first pull tab 126 connected to the first body 122 via the first connection portion 124. More specifically, the first body 122 includes an upper wing plate 122a, a lower wing plate 122b, and a connecting post 122c connecting the upper wing plate 122a and the lower wing plate 122b, and a space between the upper wing plate 122a and the lower wing plate 122b is used for passing the fastener elements 114 (shown in fig. 1) on the fastener stringer 110 to open and close the fastener elements 114. Furthermore, the first connecting portion 124 includes a receiving groove 124a formed on the upper wing plate 122a of the first body 122, a pair of mounting holes 124b disposed on opposite sides of the receiving groove 124a, and a mounting rod 124c capable of passing through the mounting hole 124b, and the first pull tab 126 has a connecting hole 126a, whereby the first pull tab 126 is disposed on the receiving groove 124a in such a manner that the mounting rod 124c passes through the connecting hole 126a and penetrates into the mounting hole 124 b. Thereby, the first pull tab 126 is connected to the first body 122 via the first connection portion 124, and is rotatable in the longitudinal direction (i.e., the direction perpendicular to the axial direction of the mounting rod 124 c). However, the invention is not limited to the specific structure and connection manner of the first slider 120 (including the first body 122, the first connection portion 124, and the first pull tab 126), which can be adjusted according to the requirement.
Similarly, the second slider 130 includes a second body 132, a second connecting portion 134 formed at the second body 132, and a second pull tab 136 connected to the second body 132 via the second connecting portion 134. Further, the second body 132 includes an upper wing plate 132a, a lower wing plate 132b, and a connecting post 132c connecting the upper wing plate 132a and the lower wing plate 132b, and a space between the upper wing plate 132a and the lower wing plate 132b is used for passing the fastener elements 114 (shown in fig. 1) on the fastener stringer 110 to open and close the fastener elements 114. Further, the second connection portion 134 is a mounting ring formed on the upper wing 132a of the second body 132 and having a through hole 134a, and the second pull tab 136 is provided with an opening at one end thereof and a connection rod 136a formed at one side of the opening, whereby the second pull tab 136 is provided on the mounting ring as the second connection portion 134 in such a manner that the connection rod 136a passes through the through hole 134 a. Thereby, the second tab 136 is connected to the second body 132 via the second connecting portion 134, and is rotatable in the longitudinal direction (i.e., the direction perpendicular to the axial direction of the connecting rod 136 a). However, the invention is not limited to 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 the requirement.
In the present embodiment, in the case where the first slider 120 is provided as an upper slider on the upper side of the slide fastener 100 and the second slider 130 is provided as a lower slider on the lower side of the slide fastener 100, the rear end of the first body 122 and the rear end of the second body 132 are opposed to each other, and further, when the first slider 120 and the second slider 130 are arranged side by side with each other in the process of moving on the fastener stringer 110, the rear end of the first body 122 and the rear end of the second body 132 can be brought into abutment with each other.
Here, the first slider 120 further includes an elastic member 128 (shown in fig. 2) disposed between the first connection portion 124 and the first pull tab 126. The elastic member 128 is disposed on the mounting rod 124c and is abutted and connected between one sidewall of the receiving groove 124a (e.g., the sidewall on the right side of the receiving groove 124a in fig. 4) and one side of the first pull-tab 126 (e.g., the concave portion on the left side of the first pull-tab 126 in fig. 4), so that the elastic member 128 applies a force to the first pull-tab 126 to automatically tilt the first pull-tab 126 toward the rear end of the first body 122 (i.e., the lower side of the zipper 100). That is, the first pull-tab 126 can be rotated in the longitudinal direction (i.e., the direction perpendicular to the axial direction of the attachment lever 124 c) by the user's operation to thereby drive the first body 122, and can also be maintained in a fixed state in which the first pull-tab 126 is tilted toward the rear end of the first body 122 (i.e., the lower side of the slide fastener 100) when the user's operation is not performed.
On the other hand, the diameter of the connecting bar 136a of the second tab 136 is set to be substantially the same as the diameter of the through hole 134a of the second connecting portion 134, and therefore the second tab 136 and the second connecting portion 134 are fitted closely to each other (light fit). That is, the second tab 136 can be rotated in the longitudinal direction (i.e., the direction perpendicular to the axial direction of the coupling bar 136 a) by the user's operation to thereby drive the second body 132, and can also be maintained in a fixed state, for example, in a state in which the second tab 136 is tilted toward the rear end of the second body 132 (i.e., the upper side of the slide fastener 100), when the user's operation is not performed.
In this way, in a state where the first body 122 and the second body 132 are pressed against each other at their respective rear ends and the second pull tab 136 is tilted toward the rear end of the second body 132 (i.e., the upper side of the slide fastener 100), the first pull tab 126 is tilted toward the rear end of the first body 122 (i.e., the lower side of the slide fastener 100) to cover and fix the second connecting portion 134 and the second pull tab 136, and the second connecting portion 134 and the second pull tab 136 are hidden inside the first pull tab 126 (see fig. 3 to 5).
Fig. 6 is a perspective view of the first pull tab 126 of fig. 2. Referring to fig. 3 to 6, in the present embodiment, a concave portion is formed on an inner side of the first pull tab 126, and the concave portion includes a first concave portion 126b corresponding to the second connecting portion 134 and a second concave portion 126c corresponding to the second pull tab 136, so that the second connecting portion 134 and the second pull tab 136 are fitted into the concave portion (including the first concave portion 126b and the second concave portion 126c) of the first pull tab 126 when the first pull tab 126 is tilted toward a rear end of the first body 122 (i.e., a lower side of the slide fastener 100) and covers and fixes the second connecting portion 134 and the second pull tab 136. Wherein 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 126 c. That is, since the second connection portion 134 is a mounting ring formed at the second body 132 and having the through hole 134a, and the second pull tab 136 is a sheet-like structure provided on the second connection portion 134, the height of the second connection portion 134 is greater than the height (i.e., thickness) of the second pull tab 136, and the width of the second connection portion 134 is smaller than the width of the second pull tab 136. Here, it is preferable that the depth of the first recess 126b corresponding to the second connection portion 134 is greater than the depth of the second recess 126c corresponding to the second pull tab 136, and the width of the first recess 126b corresponding to the second connection portion 134 is smaller than the width of the second recess 126c corresponding to the second pull tab 136. That is, the shape and size (e.g., depth) of the first recess 126b corresponds to the second connection 134, and the shape and size (e.g., depth) of the second recess 126c corresponds to the second pull tab 136.
As described above, by providing the first concave portion 126b and the second concave portion 126c having the corresponding shapes and sizes, the first tab 126 can correspond to the second connecting portion 134 and the second tab 136 having the shapes and sizes different from each other. That is, when the first tab 126 is fitted in the second connecting portion 134 and the second tab 136 in the recessed portion (including the first recessed portion 126b and the second recessed portion 126c), the first tab 126 is substantially horizontal when viewed in the lateral direction. Thus, the first pull tab 126 does not float on the second pull tab 136 and the second connection 134. In addition, since 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 tab 126, but does not penetrate through the first tab 126, when the first tab 126 is tilted toward the rear end of the first body 122 (i.e., the lower side of the slide fastener 100) and covers and fixes the second connecting portion 134 and the second tab 136, the second connecting portion 134 and the second tab 136 are completely hidden inside the first tab 126, and the outer surface of the first tab 126 remains flat and completely shields the second connecting portion 134 and the second tab 136.
More specifically, as shown in fig. 5 and 6, the first pull tab 126 has a sidewall 126d surrounding the recess (including the first recess 126b and the second recess 126 c). The side wall 126d is a relatively high portion of the outer periphery of the recess (including the first recess 126b and the second recess 126c), and may be provided partially or entirely on the outer periphery of the recess as needed. When the first pull-tab 126 is tilted toward the rear end of the first body 122 (i.e., the lower side of the slide fastener 100) and covers and fixes the second connecting portion 134 and the second pull-tab 136, the side wall 126d surrounds the outer sides of the second connecting portion 134 and the second pull-tab 136, so that the side wall 126d partially overlaps the second connecting portion 134 and the second pull-tab 136 when viewed in the lateral direction, and the second connecting portion 134 and the second pull-tab 136 are hidden inside the first pull-tab 126 when viewed in the plan view. That is, the range of the first pull tab 126 in the plane is larger than the ranges of the second connecting portion 134 and the second pull tab 136 in the plane, and therefore the first pull tab 126 completely overlaps with the second connecting portion 134 and the second pull tab 136 in a plan view.
With the above structure, the first pull tab 126 covers and fixes the entirety of the 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, the second connection portion 134 and the second tab 136 may be completely hidden inside the first tab 126 when the recess does not penetrate the first tab 126, but the second connection portion 134 and the second tab 136 may be approximately hidden inside the first tab 126 when the recess penetrates a part of the first tab 126. Further, the position of the first tab 126 in the lateral direction is restricted by the side wall 126d, so the side wall 126 d/concave portion can prevent the first tab 126 from wobbling in the lateral direction.
As a result, when the rear ends of the first body 122 and the second body 132 are pressed against each other and the second pull tab 136 is tilted toward the rear end of the second body 132 (i.e., toward the upper side of the slide fastener 100), the first pull tab 126 is automatically tilted toward the rear end of the first body 122 (i.e., toward the lower side of the slide fastener 100) by the biasing 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 the user does not perform an operation, the first pull-tab 126 can smoothly cover and fix the second pull-tab 136 and the second connection portion 134, and the second pull-tab 136 is hidden inside the first pull-tab 126, thereby reducing the possibility of the first pull-tab 126 and the second pull-tab 136 shaking.
Furthermore, since the second pull tab 136 and the second connecting portion 134 are tightly fitted to each other, and the second pull tab 136 is tilted toward the rear end of the second body 132 (i.e., the upper side of the zipper 100), and the second pull tab 136 is fastened and fixed by the second concave portion 126c of the first pull tab 126, the second pull tab 136 is pressed by the first pull tab 126 without being operated by the user, and thus the second pull tab 136 is not easily shaken. Further, since the first tab 126 is automatically tilted toward the rear end of the first body 122 (i.e., toward the lower side of the slide fastener 100) by the biasing force of the elastic member 128, and the first tab 126 is fastened and fixed to the second connecting portion 134 and the second tab 136 via the first concave portion 126b and the second concave portion 126c, and the tilting direction of the first tab 126 (toward the lower side of the slide fastener 100) and the tilting direction of the second tab 136 (i.e., toward the upper side of the slide fastener 100) are different, the first tab 126 is biased by the elastic member 128 and is fitted to the second tab 136 and the second connecting portion 134 without being manipulated by the user, and thus the first tab 126 is not easily shaken.
The above description is only one embodiment of the present invention, and for example, in other possible modifications, the concave portion provided on the inner face of the first tab 126 is not limited to the shape and size corresponding to the second connecting portion 134 and the second tab 136, and the main object of the present invention can be achieved as long as the first tab 126 can cover and fix the second tab 136 and the second connecting portion 134. The first tab 126 is not limited to being automatically tilted toward the rear end of the first body 122 (i.e., toward the lower side of the slide fastener 100) by the biasing force of the elastic member 128, and may be maintained in a state of being tilted toward the rear end of the first body 122 (i.e., toward the lower side of the slide fastener 100) by being tightly fitted to the attachment rod 124c as in the case of the second tab 136. Accordingly, the above components of the zipper 100 can be adjusted in specific structure and connection manner according to the requirement, and the invention is not limited thereto.
As described above, in the slide fastener according to the present invention, the first tab is tilted toward the rear end of the first body (i.e., toward the lower side of the slide fastener) in a state in which the first body and the second body are brought into contact with each other and the second tab is tilted toward the rear end of the second body (i.e., toward the upper side of the slide fastener), and the second tab and the second connecting portion are engaged with the second tab and the second connecting portion by the concave portion provided on the inner side of the first tab, thereby covering and fixing the second connecting portion and the second tab. In this way, compared with the prior art in which only the upper pull tab and the lower pull tab are fixed to each other by fitting, the first pull tab as the upper pull tab covers and fixes the second pull tab as the lower pull tab and the second connecting portion to which the second pull tab is connected, so that 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 substantially completely hidden inside the first pull tab, thereby reducing the possibility of the first pull tab and the second pull tab shaking. Accordingly, the zipper of the present invention can have good stability.
