[0049] (First Embodiment)

[0050] Figure 3The figure shows a zipper slider 10 (hereinafter, also referred to as "slider 10") according to the first embodiment of the present invention as viewed from above. The slider 10 according to the first embodiment of the present invention is composed of at least three parts. The three parts are a slider body 11 formed by connecting an upper wing plate 12 and a lower wing plate 13, a pull tab 19, and a rope mounting structure 21. The slider body 11 is basically the same as the Figure 1 The structure shown is the same as that of the conventional zipper slider, and is provided with a plate-shaped upper wing plate 12 and a lower wing plate 13 and a pull-tab mounting portion 14 formed on the upper wing plate 12. The lower surface of the upper wing plate 12 is connected to the upper surface of the lower wing plate 13 by a connecting column. The upper wing plate 12 and the lower wing plate 13 are respectively slender in the sliding direction of the slider. Hereinafter, the sliding direction of the slider is defined as the length direction of the slider, and the direction orthogonal to the length direction and parallel to the zipper tape is defined as the width direction of the slider. The pull-tab mounting portion 14 is formed on the surface of the upper wing plate 12 on the opposite side of the lower wing plate 13, that is, the upper surface 17. The pull-tab mounting portion 14 has a pair of left and right first members 15R, 15L protrudingly arranged on the upper surface 17 of the upper wing plate 12 and a second member 16 connecting the pair of left and right first members 15R, 15L. The pair of left and right first members 15R, 15L are arranged at intervals in the width direction of the slider. The second member 16 extends in the width direction of the slider. A pull-tab insertion path 18 extending in the front-rear direction is provided between the lower surface of the second member 16 and the upper surface 17 of the upper wing plate 12. The slider body 11 can be manufactured by injection molding of a resin material or die casting of a metal material such as a zinc alloy or an aluminum alloy.

[0051] The second component of the slider 10, i.e., the pull tab 19, has a rope-like member 20 at least partially, and the rope-like member 20 has a rope return portion 20A in the middle portion thereof, and has a pair of rope extension portions 20B, 20B connected from the rope return portion 20A. Figure 3 The end portion of one side not shown in the figure) can be connected with Figure 2 The pull tab of the conventional slider shown in the figure is similarly provided with the gripping portion 112, or may be provided as a knot of a rope. In addition, as the rope-like member 20, for example, a twisted rope formed by twisting a plurality of fiber materials, a belt-like member woven into a belt-like shape by weaving fiber materials, a member formed by extrusion molding of a resin, a member formed by injection molding of a resin, etc. can be used, but it is not particularly limited thereto.

[0052] Furthermore, the third component of the slider 10, namely, the rope mounting structure 21, is arranged in the pull-tab insertion path 18. The rope mounting structure 21 is substantially in the shape of a rectangular parallelepiped, and includes a front raised portion 22 provided at one end in the longitudinal direction and a rear raised portion 23 provided at the other end in the longitudinal direction. The rope mounting structure 21 is arranged in such a manner that the second member 16 of the slider body 11 is sandwiched between the front raised portion 22 and the rear raised portion 23. A rope return portion 20A of the rope-like member 20 is arranged on the front surface side of the front raised portion 22 of the rope mounting structure 21, and a pair of rope extension portions 20B, 20B connected from the rope return portion 20A are arranged to pass through the gaps between the side surfaces in the left-right direction of the rope mounting structure 21 and the left and right first members 15R, 15L of the slider body 11, respectively, so that the rope-like member 20 is installed so as not to fall off from the slider body 11 toward the rear. The rope attachment structure 21 can be manufactured by, for example, injection molding a resin material that is a soft member, or can be manufactured by die-casting a metal material such as a zinc alloy or an aluminum alloy.

[0053] Next, use Figures 4 to 7 The specific structure of the rope attachment structure 21 will be described. Figure 4 is a three-dimensional diagram of the rope installation structure 21, Figure 5 is a top view of the rope installation structure 21, Figure 6 is a right side view of the rope installation structure 21, Figure 7 This is a front view of the rope mounting structure 21 as viewed from the front side. Figures 4 to 7 As shown, the rope mounting structure 21 is roughly in the shape of a rectangular parallelepiped, and has an upper surface, a lower surface facing the upper surface, a front surface, a rear surface facing the front surface, a right side surface, and a left side surface facing the right side surface. The rope mounting structure 21 has a front raised portion 22 arranged at one end in the length direction, a central main body portion 24 connected to the front raised portion 22, and a rear raised portion 23 connected to the central main body portion 24 and arranged at the other end in the length direction. The central main body portion 24 is roughly flat. The thickness of the front raised portion 22 and the rear raised portion 23 in the vertical direction is thicker than that of the central main body portion 24. Between the central main body portion 24 and the front raised portion 22 is a curved surface that gradually tilts upward toward the front, and the inclined curved surface becomes the front locking surface 29, which becomes the part that is locked with the second member 16 of the slider body 11. On the other hand, a rear raised portion 23 is provided on the rear side of the central body portion 24, and a curved surface gradually inclined upward toward the rear is provided between the central body portion 24 and the rear raised portion 23, and the inclined curved surface becomes a rear locking surface 30, which becomes a portion locked with the second member 16 of the slider body 11. The front locking surface 29 and the rear locking surface 30 are respectively composed of a downward convex curved surface smoothly connected to the plane of the central body portion 24 and an upward convex curved surface smoothly connected to the downward convex curved surface.

[0054] like Figure 6As shown in FIG. 1 , the front surface 27 of the rope mounting structure 21 is an inclined surface that gradually slopes downward toward the front. On the other hand, the rear surface 28 of the rope mounting structure 21 is a plane that is substantially vertical in the vertical direction. The lower surface of the rope mounting structure 21 is a substantially flat surface (more strictly speaking, in order to set a slope for demoulding during manufacturing, such as Figure 7 As shown, there is some slope in the left and right directions).

[0055] A right groove 32R is provided on the right side surface 25R of the rope mounting structure 21 so as to extend from the front to the rear and is recessed toward the inner side of the rope mounting structure 21. A right upper edge 33R is provided above the right groove 32R so as to extend from the front to the rear, and a right lower edge 34R is provided below the right groove 32R so as to extend from the front to the rear. The right groove 32R has a curvature that is recessed into an arc shape that is approximately semicircular, and the groove is a curved surface as a whole. Similarly, a left groove 32L is provided on the left side surface 25L of the rope mounting structure 21 so as to extend from the front to the rear and is recessed toward the inner side of the rope mounting structure 21, and a left upper edge 33L and a left lower edge 34L are provided above and below the left groove 32L, respectively, so as to extend from the front to the rear. The left groove 32L has a curvature that is recessed into an arc shape that is approximately semicircular, and the groove is a curved surface as a whole. (In addition, arc shape does not mean an exact arc, but means a curved surface with an arc.)

[0056] Next, use Figure 8 , Fig. 9 as well as Figure 3 A procedure for attaching the string-like member 20 of the handle 19 to the slider body 11 using the string attachment structure 21 will be described.

[0057] Figure 8 This is a diagram showing a state after the string-like member 20 is arranged in the handle insertion path 18 of the slider body 11. The string folded portion 20A of the string-like member 20 passes through the handle insertion path 18 from the rear side toward the front side.

[0058] Next, if Fig. 9As shown, the rope mounting structure 21 is arranged between a pair of rope-like members 20 (rope extension parts 20B, 20B) extending from the rope folding part 20A. The rope mounting structure 21 is positioned on the upper surface 17 of the upper wing plate 12 of the slider body 11 in a state close to the rope folding part 20A of the rope-like member 20. Then, while maintaining this positioned state, the rope mounting structure 21 and the rope-like member 20 move backward toward the pull-tab insertion path 18. In a state where the rope mounting structure 21 is in contact with the pull-tab mounting part 14, in a state where no force is applied to the rear, the height of the rear raised part 23 of the rope mounting structure 21 in the vertical direction is greater than the height of the pull-tab insertion path 18 in the vertical direction. Furthermore, when force is applied to the rear, the rear raised part 23 is reversibly deformed and pushed into the interior of the pull-tab insertion path 18. That is, when the rear raised portion 23 is located inside the pull-tab insertion path 18, the upper surface of the rear raised portion 23 is strongly pressed against the lower surface of the second member 16 of the slider body 11, and the rear raised portion 23 is in a state of elastic deformation (in addition, the second member 16 sometimes also undergoes elastic deformation). In this state, the rope mounting structure 21 is pushed into the pull-tab insertion path 18 by overcoming the friction force generated between the rope mounting structure 21 and the inner surface of the pull-tab insertion path 18. When the rear raised portion 23 is arranged behind the pull-tab insertion path 18, it becomes Figure 3 The status shown. Figure 3 In the state, the second member 16 of the pull-tab mounting portion 14 is clamped by the front raised portion 22 and the rear raised portion 23 of the rope mounting structure 21, and the rope mounting structure 21 is fixed to the slider body 11. In this case, from the perspective of suppressing the shaking of the mounted state of the rope mounting structure 21, it is preferable that the front locking surface 29 of the front raised portion 22 and the rear locking surface 30 of the rear raised portion 23 are completely in close contact with the second member 16 of the pull-tab mounting portion 14. In addition, it is preferable that the upper surface of the central body portion 24 of the rope mounting structure 21 is completely in close contact with the lower surface of the second member 16.

[0059] The cord folding portion 20A of the pull tab 19 installed in the above-mentioned manner is installed on the slider body 11 in a manner that is at least located below the upper surface (the highest position of the upper surface) of the second member 16 of the pull tab mounting portion 14, and a pair of cord-like members 20 extending from the cord folding portion 20A are also installed on the slider body 11 in a manner that passes through the pull tab insertion path 18 and extends to the rear side of the slider 10. In other words, the cord-like member 20 of the pull tab 19 is located below the upper surface of the second member 16. Therefore, compared with the prior art in which the cord-like member 20 is always exposed to the upper surface side of the second member 16 of the pull tab mounting portion 14, the effect on the beauty of the slider 10 observed from the upper surface is small.

[0060] Here, if Figure 6As shown in FIG. 2 , the front raised portion 22 of the rope mounting structure 21 is formed to be raised upward larger than the rear raised portion 23. Figure 3 In the state, even if a force toward the rear of the slider is applied to the rope mounting structure 21 due to pulling the pull tab 19 toward the rear of the slider, the rope mounting structure 21 will not easily enter the pull tab insertion path 18.

[0061] In addition, the front surface 27 of the rope mounting structure 21 is formed as follows Figure 6 Therefore, when the pull tab is pulled strongly backward so that a force toward the rear side of the slider is applied to the cord mounting structure 21, the cord return portion 20A slides upward along the inclined surface of the front surface 27 of the cord mounting structure 21, and the cord return portion 20A comes to the same vertical position as the front protrusion 22. Therefore, the force that attempts to cause the cord mounting structure 21 to fall backward acts on the cord mounting structure 21. Figure 6 The force indicated by the arrow X can be directly received by the pull-tab mounting portion 16 of the slider body via the front raised portion 22, thus further exerting the effect of not being easy to fall off. Figure 6 The force indicated by the arrow Y acts as a moment (at the position indicated by the arrow Y) to cause the rope mounting structure 21 to enter the interior of the pull-tab insertion path 18 with the periphery of the front locking surface 29 of the front raised portion 22 as a fulcrum. Figure 6 Therefore, the effect of the rope mounting structure 21 not being easy to fall off will be reduced.

[0062] In addition, in Figure 3 When the rope mounting structure 21 is mounted on the slider body 11, it is preferred to make the front raised portion 22 and the rear raised portion 23 as inconspicuous as possible from the perspective of aesthetics. Figure 3 When observed from above, the maximum length of the exposed part of the front raised portion 22 or the rear raised portion 23 in the front-to-back direction is preferably smaller than the length of the front-to-back direction at the center position of the second component 16 of the pull-tab mounting portion 14 in the left-right direction. Specifically, the length of the exposed front raised portion 22 or the rear raised portion 23 in the front-to-back direction is preferably less than 60% of the length of the second component 16 of the pull-tab mounting portion 14 in the front-to-back direction.

[0063] Next, use Fig.10 The relative relationship of the dimensions of the components in a state where the cord attachment structure 21 is attached to the inside of the pull-tab insertion path 18 of the slider body 11 will be described. Fig.10 This is a diagram of a slider viewed from the rear to the front, in which the slider body 11 is not passed through the rope-like member 20 but only the rope mounting structure 21 is installed. Fig.10In the state where the cord attachment structure 21 is installed in this way, the pull-tab insertion path 18 becomes two or so cord insertion holes 18R and 18L due to the cord attachment structure 21. Fig.10 The length shown by r1 is the distance between the lead line L1 extending in the vertical direction from the deepest part of the right groove 32R of the rope mounting structure 21 and the lead line L2 extending in the vertical direction from the outermost part of the pull-tab insertion path 18 in the left-right direction. For convenience, it is called the rope threading hole reference length r1. Here, when the thickness of the rope-like member 20 passing through the left and right rope threading holes 18R, 18L in the natural state is set to r2, the rope threading hole reference length r1 is designed to be an appropriate size in relation to the thickness r2 of the rope-like member. If the general use of the zipper is considered, the pull-tab 19 is preferably fixed to the slider body 11 as much as possible without shaking or moving except when the zipper is operated. Therefore, the rope threading hole reference length r1 is preferably designed to be smaller than the thickness r2 of the rope-like member in the natural state. By designing the dimensions in this way, when the rope installation structure 21 is installed on the slider body 11, the rope-like member 20 of the pull tab 19 is compressed by the left and right rope-threading holes 18R and 18L, and the rope-like member 20 no longer moves freely relative to the left and right rope-threading holes 18R and 18L. Preferably, the rope-threading hole reference length r1 is preferably 50% to 80% of the thickness r2 of the rope-like member in the natural state. By setting in this way, it is also advantageous in the following aspects: when the rope installation structure 21 is installed on the slider body 11, the rope installation structure 21 will not be compressed more than necessary, and the installation member 21 can be pushed into the pull tab insertion path 18 with a moderate force. A pair of rope extension portions 20B, 20B connected to the rope return portion 20A are arranged to pass through the gaps between the left and right side surfaces of the rope mounting structure 21 and the first components 15R, 15L of the slider body 11, respectively. In more detail, the rope mounting structure 21 has a right groove 32R and a left groove 32L, and a pair of rope-like components 20 (to be precise, a pair of rope extension portions 20B, 20B) extending from the rope return portion 20A pass between the left and right pair of grooves (32R, 32L) and the left and right pair of first components (15L, 15R).

[0064] Fig.10The length d1 shown is the length (width) of the rear raised portion 23 of the rope mounting structure 21 in the left-right direction. For convenience, this d1 is referred to as the rear raised portion width d1. If the rear raised portion width d1 is large, the exposed area of ​​the rope mounting structure 21 becomes large, the appearance is not beautiful, and the friction force generated when the rope mounting structure 21 is passed through the pull-tab insertion path 18 becomes large. On the contrary, if the rear raised portion width d1 is too small, the left and right rope holes 18R and 18L become larger, so there is a problem that the rope-like member 20 will not be in a constrained state relative to the left and right rope holes 18R and 18L. Therefore, the rear raised portion width d1 is preferably approximately 40% to 70% of the maximum width of the pull-tab insertion path 18 in the left-right direction.

[0065] By setting it in the above manner, according to the present invention, the rope-like member 20 is not exposed in a manner that it exceeds the pull-tab mounting portion 14, and is arranged by passing the lower side of the pull-tab mounting portion 14, so that the design of the original slider body 11 in a top view is not visually obstructed by the rope-like member 20. In particular, when the slider 10 is viewed from the side, it does not become a state where the thickness of the rope-like member 20 is stacked on the thickness of the pull-tab mounting portion 14, but only forms the thickness of the original slider body 11, so the thinness and smooth curve design of the original slider body 11 in a side view are not destroyed.

[0066] Furthermore, according to the present invention, even a user who uses the slide fastener or a sewing operator who sews the slide fastener to clothing or the like can attach the cord pull tab 19 to the slider body 11 through a simple operation process without requiring particularly complicated operations.

[0067] In addition, the previous rope pull tabs required the action of winding the rope around the slider body, so there was also a side that was difficult to achieve mechanical automation, but the installation action of the rope pull tab of the present invention is the action of moving the rope in the front-back direction, so it is also advantageous in terms of mechanical automation.

[0068] (Second Embodiment)

[0069] Next, a second embodiment of the present invention will be described. Fig.11 The figures show a cord attachment structure 21B in a slider according to a second embodiment of the present invention. The left figure A is a side view of the cord attachment structure 21B as viewed from the right side, and the right figure B is a rear view of the cord attachment structure 21B as viewed from the rear.

[0070] like Fig.11 As shown, in the second embodiment of the present invention, the right side 25R and the left side 25L of the rope installation structure 21B are not provided with the grooves 32R and 32L provided in the first embodiment, and the right side 25R and the left side 25L are flat. Fig.11In the figure, the right side surface 25R and the left side surface 25L are shown as planes vertical in the up-down direction, but they may be planes inclined relative to the up-down direction. In addition, in the second embodiment, the inclination of the front surface 27 of the rope mounting structure 21B is small compared with the first embodiment, and the length of the front raised portion 22 in the front-to-back direction is correspondingly long. In addition, the front surface 27 of the rope mounting structure 21B may be set as a plane vertical in the up-down direction instead of an inclined surface.

[0071] According to the second embodiment, the strength of the rope installation structure 21B itself becomes stronger, and the risk of damage due to aging and repeated removal and installation operations is reduced. In addition, according to the second embodiment, there are advantages such as the mold used for manufacturing the rope installation structure 21B is simplified, and poor filling of the material in the mold during manufacturing is less likely to occur.

[0072] (Third Embodiment)

[0073] Next, a third embodiment of the present invention will be described. Fig.12 The figures show a cord mounting structure 21C in a slider according to a third embodiment of the present invention. Figure A on the left is a side view of the cord mounting structure 21C as viewed from the right, and Figure B on the right is a rear view of the cord mounting structure 21C as viewed from the rear.

[0074] like Fig.12 As shown, the third embodiment of the present invention does not have the lower right edge 34R and the lower left edge 34L provided in the first embodiment on the lower side of the rope mounting structure 21C. In addition, the left and right grooves 32R and 32L are not roughly semicircular arc-shaped as in the first embodiment, but are roughly 1 / 4 arc-shaped. In addition, the front side of the left and right grooves 32R and 32L of the rope mounting structure 21C is offset toward the rear side, and the lower side of the front surface of the rope mounting structure 21C becomes an offset recess 36 cut into a curved shape. In other words, the rope mounting structure 21C has an offset recess 36 provided at least on the lower surface on the opposite side of the front raised portion 22. As a result, a rope storage space 37 is formed on the lower side of the front surface of the rope mounting structure 21C.

[0075] According to the third embodiment, the cord folding portion 20A of the pull tab 19 is accommodated in the cord storage space 37 provided on the lower side of the front surface of the cord mounting structure 21C. Therefore, the cord folding portion 20A can be completely hidden from the surface (upper surface) of the slider 10, or only a portion of it can be exposed. Therefore, the appearance of the slider 10 is less likely to be affected by the rope-like member 20.

[0076] (Fourth Embodiment)

[0077] Next, a fourth embodiment of the present invention will be described. Fig.13The figure shows the rope installation structure 21D in the slider of the fourth embodiment of the present invention, the figure A on the left is a stereoscopic view of the back side (lower side) of the rope installation structure 21D, and the figure B on the right is a rear view of the rope installation structure 21D viewed from the rear. Fig.14 1 is a diagram showing a slider body 11D of a slider 10 according to a fourth embodiment of the present invention. Fig.14 The illustrated embodiment is an embodiment of a slider body 11D in which the width of the second member 16 of the pull-tab attachment portion 14 in the left-right direction is designed to be relatively large.

[0078] The rope attachment structure 21D of the fourth embodiment of the present invention does not support the rope-like member 20 by the grooves 32R and 32L provided on the left and right as in the previous embodiments, but Fig.13 As shown, the rope-like member 20 is designed to pass through the left and right internal passages 39R and 39L provided inside the rope mounting structure 21D. The right internal passage 39R is divided by the flat right wall 40R and the central separation wall 40C provided in the rope mounting structure 21D, and the left internal passage 39L is divided by the left wall 40L and the central separation wall 40C. The front side of the central separation wall 40C is offset toward the rear side, and the lower side of the front surface of the rope mounting structure 21D becomes an offset recess 36 cut into an angle of approximately 90 degrees. As a result, a rope storage space 37 is formed on the lower side of the front surface of the rope mounting structure 21D.

[0079] According to the fourth embodiment, even if Fig.14 The slider designed with the second member 16 of the pull-tab mounting portion 14 having a relatively large width in the left-right direction can also arrange the rope-like member 20 in parallel and aligned at a position close to the center of the left-right direction of the slider, so that the rope-like member 20 extending through the left and right internal passages 39R and 39L also looks like hanging down in parallel, making the slider more beautiful as a whole. In addition, when the rope mounting structure 21D is mounted on the slider body 11, the rigidity of the rope-like member 20 as a whole is reduced and it is easy to bend due to the existence of the left and right internal passages 39R and 39L, so the operating force for pushing the rope mounting structure 21D into the pull-tab insertion path 18 of the slider body 11 can also be small. In addition, the state in which the rope return portion 20A of the pull-tab 19 is accommodated in the rope storage space 37 is the same as in the third embodiment.

[0080] (Fifth Embodiment)

[0081] Next, a fifth embodiment of the present invention will be described. Fig.15The fifth embodiment is a diagram showing a cord mounting structure 21E in a slider according to a fifth embodiment of the present invention, wherein the left side view A is a side view of the cord mounting structure 21E as viewed from the right side, and the right side view B is a rear view of the cord mounting structure 21E as viewed from the rear side. The fifth embodiment is opposite to the fourth embodiment described above, and is an embodiment of a slider (not shown) suitable for a second member 16 of a pull-tab mounting portion 14 having a relatively small width in the left-right direction.

[0082] like Fig.15 As shown, the fifth embodiment of the present invention has a smaller width in the left-right direction of the rope mounting structure 21E than the above-mentioned embodiments. Specifically expressed as a numerical value, the width in the left-right direction of the rope mounting structure 21E is about 30% to 60% thinner than the maximum height in the up-down direction of the rope mounting structure 21E (i.e., the height of the portion of the front raised portion 22). In addition, a rear recess 42 that penetrates in the left-right direction is provided near the center of the rear surface 28 of the rope mounting structure 21E.

[0083] According to the fifth embodiment, the exposed portion of the cord mounting structure 21E becomes smaller, so the overall aesthetics of the slider is not easily affected by the cord mounting structure 21E. In addition, by providing the rear recess 42, the rigidity of the rear surface 28 side of the cord mounting structure 21E is reduced and it is easy to bend, so the operating force for pushing the cord mounting structure 21E into the pull-tab insertion path 18 of the slider body 11 can also be small. In addition, the fifth embodiment is not necessarily only applicable to sliders in which the left-right width of the second member 16 of the pull-tab mounting portion 14 is designed to be relatively small, for example, relative to Figure 3 The slider shown can also be applied in the case where it is desired to arrange the string-like member 20 with a sufficient gap between the slider body 11 and the string attachment structure 21 .

[0084] (Sixth Embodiment)

[0085] Next, a sixth embodiment of the present invention will be described. Fig.16 The figures show a cord attachment structure 21F in a slider according to a sixth embodiment of the present invention. Figure A on the left is a side view of the cord attachment structure 21F as viewed from the right, and Figure B on the right is a rear view of the cord attachment structure 21F as viewed from the rear.

[0086] The rope mounting structure of each embodiment described above includes a front raised portion 22 and a rear raised portion 23 on the upper surface as a portion for mounting to the slider body 11. Fig.16As shown, the sixth embodiment of the present invention does not have the front raised portion 22 and the rear raised portion 23, but instead, the rope mounting structure is provided with a covering member 44 on the upper surface. A storage space 47 capable of storing the second member 16 of the pull-tab mounting portion 14 is provided between the covering member 44 and the central main body 24. The covering member 44 is supported in a cantilever shape by a supporting column 45 extending upward from the front surface 27 side of the rope mounting structure 21F, and a protrusion 46 extending downward is provided at its front end. If the installation steps of the rope mounting structure 21F of the sixth embodiment constructed in this way to the slider body 11 are described, first, the front of the second member 16 of the pull-tab mounting portion 14 is inserted from the gap between the protrusion 46 and the rear surface 28, and when the second member 16 is completely inserted into the storage space 47, the protrusion 46 engages with the rear side of the second member 16. As a result, the second member 16 will not easily pass out of the storage space 47, and the rope mounting structure 21F is firmly installed on the slider body 11.

[0087] According to the sixth embodiment, the cover member 44 is supported in a cantilever shape and is easily flexed, and is easily attached to the slider body 11. Although the cover member 44 covers the pull-tab attachment portion 14 and is exposed, it has the advantage that a design or logo can be added to the upper surface 48 of the cover member 44.

[0088] (Seventh Embodiment)

[0089] Next, a seventh embodiment of the present invention will be described. Fig.17 This is a diagram showing a slider body 11G according to a seventh embodiment of the present invention and a state where a cord attachment structure 21G is attached to the slider body 11G. For convenience, this diagram shows a state where only the cord attachment structure 21G is attached but the cord pull tab 19 is not attached.

[0090] like Fig.17 As shown, in the seventh embodiment of the present invention, the front side edge 16F and the rear side edge 16B of the second member 16 of the pull-tab mounting portion 14 of the slider body 11G are curved. In matching with the curved shape of the second member 16, the front raised portion 22, the front locking surface 29, the rear raised portion 23, and the rear locking surface 30 of the rope mounting structure 21G are also configured to have curved edges.

[0091] According to the seventh embodiment, the curved surface on the cord attachment structure 21G side is naturally adjusted in the center of the left-right direction according to the shape of the curved surface on the second member 16 side, so the cord attachment structure 21G is firmly fixed to the slider body 11G. In addition, in terms of appearance design, the curved surface shapes match each other, and a beautiful appearance can be obtained.

[0092] (Eighth Embodiment)

[0093] Next, an eighth embodiment of the present invention will be described. Fig.18 This is a diagram showing a situation where a rope installation structure 21 and a rope-like member 20 are installed on a slider 10 of an eighth embodiment of the present invention. The eighth embodiment is different from the first embodiment in that the rope installation structure 21 and the rope-like member 20 are installed from the rear side to the front side of the slider 10. The rope installation structure 21 and the rope-like member 20 are located on the rear side of the upper surface 17 of the upper wing plate 12 of the slider body 11 instead of the front side and move forward toward the pull-tab insertion path 18, which is different from the above-mentioned Figure 8 and Fig. 9 The eighth embodiment is not suitable for a case where the operating direction of the slider 10 is in the vertical direction (the direction of gravity), such as when the zipper is used on the front of a garment, but is suitable for a case where the operating direction of the slider 10 is in the horizontal direction rather than the vertical direction, such as when the zipper is installed in the horizontal direction at the opening and closing part of the chest pocket of a garment. As other use examples of the eighth embodiment, for example, when a pair of sliders 10 are used in a state where they touch each other on the front side, such as at the opening of a handbag or a backpack, it is sometimes preferred from the perspective of the operability of the slider 10 to install it in a state where the operating part of the pull tab 19 extends to the front side of the slider as in the eighth embodiment.

[0094] (Ninth Embodiment)

[0095] In the above-mentioned embodiments, the rope mounting structure 21, 21B, 21C, 21D, 21E, 21F, 21G is mounted on the slider body 11 separately from the slider body 11, but the rope mounting structure 21 may be configured to be integral with the slider body 11 from the beginning without being separated from the slider body 11. For example, when the slider body 11 is manufactured by resin injection molding, a structure corresponding to the rope mounting structure 21 may be integrally injected with resin into the space between the second member 16 of the slider body 11 and the upper wing plate 12.

[0096] According to the ninth embodiment, a user who uses the zipper or a sewing operator who sews the zipper to clothes or the like can form the pull tab 19 by simply inserting the string member 21 into the slider body 11 and connecting the two ends of the passed string member 21. In addition, there is also an advantage that the number of components of the slider 10 is reduced by one.

[0097] As described above, according to the sliders of various embodiments of the present invention, it is possible to reduce the impact on design caused by the exposure of the rope portion to the surface of the sliders of the conventional winding rope type with rope pull tabs, to improve the convenience of installing the rope pull tab to the slider, and to enjoy other various effects as described in the above specification.

[0098] In addition, the present invention is not limited to the above disclosed embodiments, and it is also possible to appropriately utilize the technology recognized by those skilled in the art as the technology that is substantially the same as the various technical matters described in the embodiments of the present invention or the technology that exerts the same effect, or to use it as a replacement technology, or to add it by appending. In addition, it is also possible to implement the characteristic structures of the above embodiments by recombining them with each other.

[0099] In addition, throughout the present specification, the parts described with reference numerals in the drawings are recorded as the minimum necessary components in each embodiment of the present invention, and it does not mean that the present invention is composed of only the parts described with reference numerals in the drawings.
