Description

Slider for zipper and common zipper chain

The present invention relates to a slider for a zipper, and more particularly to a slider having a keyhole portion that can be locked by a padlock or the like.

In China Laid-Open Publication No. CN204599598U (Patent Document 1), there are disclosed slide pieces with lock holes that are installed in two sets of a common zipper chain. These two sliders are the same and each includes: a cantilever-shaped pull-tab connecting portion 120 for connecting the pull-tab to the slider body (see FIG. 8); and a keyhole portion 130 that connects with the pull-tab connecting portion 120 abuts on the side of the guide pillar in the longitudinal direction. The two sliders are installed on a common zipper chain in such a manner that the side ends of the guide pillars in their length directions can face each other. FIG. 8 shows a state in which such two sliders are mounted on a common zipper chain (not shown), and the side ends of the guide pillars in the longitudinal direction are abutted. The slide members are designed so that the lock holes of the respective lock hole portions 130 overlap in the width direction in the docked state in FIG. 8. If a padlock or the like is locked at the keyholes overlapping in the width direction in this way, it becomes difficult to move the two sliders in a direction to pull away from each other in the zipper chain, so that the zipper chain cannot be opened. According to this feature, the slider of Patent Document 1 is often used for a travelling bag and the like.

Referring to FIG. 8, the slider connecting portion 120 of the slider includes: a base end portion 120A, which rises upward from a base end 121 on the column side (front) of the longitudinal direction guide; and a middle portion 120B, which ends from above the base end portion 120A. The side (rear) extending from the side of the guide pillar in the longitudinal direction extends; and the free end portion 120C extends downward from the rear end of the middle portion 120B, and finally terminates at the free end 122. In this slider, a slider (not shown) is inserted from the gap between the free end 122 of the pull-tab connecting portion 120 and the upper surface 111a of the slider body, and the pull is pressed so that the free end 120C approaches the upper surface. The tab connecting portion 120 is used to connect the pull tab to the tab connecting portion 120. Fig. 8 shows the state after the pull-tab connecting portion 120 is compressed. In the above-mentioned slider, even after the pressing, there is a gap between the free end 122 of the pull-tab connecting portion 120 and the upper surface 111a of the slider body. . Therefore, there have been cases where clothes and the like have been caught in the gap.

Further, in the slider described above, the middle portion 120B and the free end portion 120C of the pull-tab connecting portion 120 are bent at a substantially right angle, the angle protrudes outward, and the top end T112 of the keyhole portion 130 of the keyhole portion 130 is also outward (upward) )protruding. In addition, the height of the intermediate portion 120B from the upper surface 111a decreases from the both ends in the longitudinal direction to the intermediate side in the longitudinal direction. Therefore, the upper and outer side surfaces of the intermediate portion 120B become a curved surface recessed inward. Further, the outer side surface of the pull-tab connecting portion 120 (including the outer side surface of the middle portion 120B) between the top end T111 of the connecting portion and the keyhole portion T112 that is the highest from the upper surface 111a is bent inwardly. Therefore, for example, when the travel bag on which the slider is installed hits a wall or a floor and the slider is impacted, both ends of the concavely curved outer surface, that is, the top end of the keyhole portion T112 and the top including the connection portion The above-mentioned corner portion of T111 relatively projects outward, so the impact is likely to be concentrated on the top end T112 or corner portion of the keyhole portion, which may cause deformation of the pull-tab connecting portion 120, the keyhole portion 130, or the slider body.

In the slider described above, the outer side surface S103 of the free end portion 120C of the pull tab connecting portion 120 extends toward the upper middle portion 120B side at a steep angle (approximately 80 degrees) perpendicular to the upper surface 111a. Due to the existence of the free end portion 120C rising at a steep angle with respect to the upper surface 111a, and the above-mentioned corner portion protruding outward and the top end T112 of the keyhole portion, the feel of the slider becomes rough, especially in the figure In the butt joint state of 8, there are irregularities on the contours of the pull-tab connecting portion 120 and the keyhole portion 130 viewed from one direction in the width direction, so that the appearance is not smooth.

Patent Document 1: China Publication No. CN204599598U

Therefore, an object of the present invention is to provide a slider for a slide fastener, which has no gap between the two ends of the pull-tab connecting portion and the upper surface of the slider body, and that the pull-tab connecting portion and the keyhole portion do not face inward. It is formed as a concave portion or a portion that projects relatively outward, and further has a good feel, and the appearance of the pull-tab connecting portion and the keyhole portion is smooth.

In order to solve the above-mentioned problem, according to one aspect of the present invention, a slider is provided, which is provided with an upper wing plate, a lower wing plate, and a guide pillar connecting the upper and lower wing plates on one side in the longitudinal direction between the upper and lower wing plates. A slider for a slide fastener, further comprising: a pull-tab connecting portion, one end of which is connected to one side in the longitudinal direction of the upper surface of the upper wing plate, and the other end of which is connected to the other side of the upper surface of the upper wing plate in the longitudinal direction. To define a pull-tab connection hole; and a keyhole portion that expands from the one end side of the pull-tab connection portion to the length direction side to define a lock hole; and the pull-tab connection portion and the keyhole portion define a bend The outer side surface, the outer side surface from the other end of the pull-tab connection portion to the keyhole portion from the top surface of the upper wing plate with the highest height from the upper surface of the upper wing plate, the height from the upper surface of the upper wing plate It becomes taller and convex outward.

The slider of the present invention includes a slider connecting portion and a keyhole portion on the slider body. One end of the slider connecting portion is connected to one side in the longitudinal direction of the upper surface of the upper wing plate (the upper surface of the slider body) and the other end. Connected to the other side in the length direction. Therefore, there is no gap between one end and the other end of the pull-tab connecting portion and the upper surface of the slider body.

In the present invention, the above-mentioned pull-tab connecting portion and the keyhole portion define a curved outer side that is convex outward, and the height of the outer side from the upper surface of the upper wing plate moves toward the other end of the pull-tab connecting portion toward The top of the keyhole gradually becomes higher. Here, the so-called "the height from the upper surface of the upper wing plate gradually becomes higher as the other end of the connecting part of the pull tab goes to the top of the keyhole part", means that the other end of the connecting part of the self-pull sheet moves toward the keyhole part The top, the height from the upper surface of the upper wing does not become lower, but gradually increases. As long as the height does not decrease, there may be a flat portion having a constant height locally. It is defined by the pull-tab connecting portion and the keyhole portion. As the height gradually increases from the other end of the pull-tab connecting portion to the top of the keyhole portion, the outer side defines a curved shape protruding outward. Outside ". Here, the "outer side" refers to the side opposite to the inner side of the pull-tab connection portion facing the pull-tab connection hole, and the "outer side" refers to the inner side of the pull-tab connection portion facing the pull-tab connection hole as The surface on the opposite side, when viewed from one direction in the width direction (see FIG. 1), refers to the surface that defines the outline of the pull-tab connecting portion and the keyhole portion. The “curved outward convex shape” means a curved surface convex outward as opposed to a curved surface recessed inwardly between the top end T111 of the connecting portion and the top end T112 of the keyhole portion shown in FIG. 8. . In the present invention, "from the other end of the connecting portion of the pull tab to the top of the keyhole portion, the height from the upper surface of the upper wing plate gradually becomes higher and curved outwardly convexly outward", which is not formed inward It is a concave part or a part protruding relatively outward. Therefore, the handle of the pull-tab connecting portion and the keyhole portion is smooth, and the appearance of the pull-tab connecting portion and the keyhole portion is smooth.

In the present invention, the pull-tab connection portion and the keyhole portion may be metal parts such as zinc alloy and aluminum alloy that are integrally cast with the upper wing plate, but are not limited thereto. In addition, a part of the pull-tab connecting portion or the keyhole portion may be made of resin or metal parts that can be attached or detached.

In one embodiment of the present invention, the pull-tab connection portion has a top end of the connection portion having the highest height from the upper surface of the upper wing plate, and the lock hole portion expands from the top end of the connection portion to the lengthwise side. The outer surface includes: a first outer surface that reaches the top of the connecting portion from the other end in the pull-tab connecting portion; and a second outer surface that reaches the top of the locking hole from the top of the connecting portion in the locking hole portion. And is gently connected to the first outer surface. In this case, the first outer surface of the pull-tab connecting portion gradually increases from the other end of the pull-tab connecting portion to the top of the connecting portion from the upper surface of the upper wing plate, and moves toward the second of the keyhole portion. The outer side surface is connected to it gently, and the second outer side surface gradually increases in height from the top surface of the upper wing plate from the top end of the connecting portion to the top end of the keyhole portion. Therefore, the first outer surface of the pull-tab connecting portion and the second outer surface of the keyhole portion become convexly curved outer surfaces. The convex-curved outer surface is the middle distance from the other end of the pull-tab connecting portion to the keyhole portion. The tops of the keyhole portions having the highest height on the upper surface of the upper wing plate are smoothly connected, and the height from the upper surface of the upper wing plate gradually increases.

In one embodiment of the present invention, a difference between a height of the top end of the keyhole portion of the keyhole portion and a top end of the link portion of the pull-tab connecting portion from the upper surface is 1 mm or less. In this embodiment, the second outer side surface between the distal end of the connection portion and the distal end of the keyhole portion becomes a substantially flat surface close to the horizontal plane. Such a surface can withstand an impact on a surface, so the impact resistance is improved. Especially in a docking state (refer to FIG. 5 and the like) where the slider is used as a set of two for a shared zipper chain and the respective longitudinal ends (the side ends of the guide post) are in contact with each other. The second outer side surface extending between the top ends of the two sliding members at the top end of the keyhole portion and located in the middle of the longitudinal direction becomes a substantially flat surface close to the horizontal plane, and can withstand impact on this surface, so the impact resistance is improved.

In one embodiment of the present invention, the outer surface of the other end side of the pull-tab connecting portion forms an angle of 55 to 65 degrees with respect to the upper surface of the upper wing plate. Since the other end side (opposite to the keyhole portion) of the pull-tab connecting portion is lifted from the upper surface of the slider body within this angle range, the side ends of the guide columns of the two sliders can be shared. In the state of butt joint in the zipper chain (refer to FIG. 5), the outlines (viewed from one direction in the width direction) of the outer side surfaces of the pull-tab connecting portion and the keyhole portion of the two sliders are bowed.

In one embodiment of the present invention, the two above-mentioned sliders can be installed on a common zipper chain in such a manner that the ends on one side in the longitudinal direction are opposite to each other, and are connected to the ends on the one side in the length direction of each slider. In the state, the keyholes of the respective keyhole portions overlap in the width direction. In this case, in a state where the lock holes of the respective sliders overlap in the width direction (refer to FIG. 5), an outer side surface is defined by a pull-tab connecting portion and a lock-hole portion of the two sliders. The other end of the connecting part (the end opposite to the guide pillar side) is smoothly connected to the top of the keyhole part, and the height from the upper surface of the upper wing plate gradually increases, and from the other end of the connecting part of the other tab (The end opposite to the guide pillar side) is connected to the top of the keyhole part gently, and the height from the upper surface of the upper wing plate gradually increases. Therefore, as shown in FIG. 5, the above-mentioned outer surfaces of the pull-tab connection portion and the keyhole portion of the two sliders in the docked state are viewed from the side (one direction in the width direction), and define the portion that does not protrude to the outside or the direction Contour of the bow shape of the inner recessed part.

According to another aspect of the present invention, a slider is provided, which is provided with an upper wing plate, a lower wing plate, and a guide post connecting the upper and lower wing plates on one side in the longitudinal direction between the upper and lower wing plates, and is arranged along each other. The sliders are mounted on two sets of the common zipper chain in opposite length directions, and each of the sliders includes a pull-tab connecting portion, one end of which is connected to the one side of the upper surface of the upper wing plate in the length direction, and One end is connected to the other side in the length direction of the upper surface of the upper wing plate to define a pull-tab connection hole; and a keyhole portion that expands from the one end side of the pull-tab connection portion to the one side in the length direction and defines The locking hole portion and the locking hole portion define a curved outer side surface, and the height of the outer side surface from the other end of the pulling plate connecting portion to the locking hole portion from the upper surface of the upper wing plate The top of the highest keyhole part gradually increases in height from the upper surface of the upper wing plate and protrudes outward; in the shared zipper chain, the ends in the lengthwise direction of each of the two sets of sliders are opposite to each other. In the state Keyhole keyhole portion of the above-described overlap the widthwise direction. These sliders are substantially equivalent to the sliders for the aforementioned slide fasteners, respectively.

In the present invention, one end of the pull-tab connecting portion on the slider body is connected to one side in the length direction of the upper surface of the slider body, and the other end is connected to the other side in the length direction. There is no gap between one end and the upper surface of the slider body, so that clothes and the like do not catch on the gap. In addition, the pull-tab connecting portion and the keyhole portion define a curved outer side surface, and the outer side height from the other end of the pull-tab connecting portion to the top of the keyhole portion of the keyhole portion from the upper surface of the upper wing plate It becomes taller and convex outward. Since the outer side surface does not form a concave portion toward the inside, it does not project relative to the outside and the portion where the impact may be concentrated. In addition, the handle of the pull-tab connecting portion and the keyhole portion is smooth and not rough, and the design of the pull-tab connecting portion and the keyhole portion can also give a smooth impression.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the present invention is not limited to these embodiments, and can be appropriately modified within the scope of patent applications and their equivalents. 1 to 3 are a side view, a perspective view, and a plan view showing a slider 1 for a slide fastener according to an embodiment of the present invention. The slider 1 can move the zipper chain in one direction (right side on the paper surface of FIG. 1) by moving it in the length direction of the zipper chain (not shown), and can pull the zipper chain in the other direction (in the length direction) The left side of the paper in Figure 1) is moved, and the zipper chain is pulled apart. In this specification, the length direction of the slider 1 is the same as the length direction of the zipper chain, and the left-right direction on the paper surface in FIG. 1 is the length direction of the slider 1. Hereinafter, the right side of the paper surface in FIG. 1 is also referred to as the front, and the left side thereof is referred to as the rear. The width direction of the slider 1 is the left-right direction on the paper surface of FIG. 3. The slider 1 includes: a slider body 10; a semi-circular pull-tab connecting portion 20 provided on the slider body 10 to connect the pull-tab 40 (see FIG. 4); and a keyhole portion 30 for sliding The piece body 10 expands forward from the pull-tab connecting portion 20 to define a circular keyhole 30a. The pull-tab 40 has a pull-tab hole 40 a through which the pull-tab connecting portion 20 passes. FIG. 4 is a perspective view similar to FIG. 2, showing a state where the pull tab 40 is connected to the pull tab connecting portion 20. The pull-tab connecting portion 20 and the upper surface 11 a of the slider body 10 define a closed pull-tab connecting hole 20 a for connecting the pull-tab 40 and penetrating in the width direction.

The slider body 10 includes an upper wing plate 11, a lower wing plate 12, and a guide post 13 that connects the upper and lower wing plates 11 and 12 in front. Between the upper and lower wings 11, 12 are defined two introduction ports 14 opened on both sides in the width direction of the guide post 13, an engagement port 15 opened at the rear, and an approximate Y connecting the introduction port 14 and the engagement port 15 Zigzag chain path. Reference numeral 11b in FIG. 1 is an upper flange portion, and the upper flange portion protrudes downward from both side portions in the width direction of the upper wing plate 11 to restrict the fastener elements of the zipper chain from derailing from the fastener element path.

One end 21 of the pull-tab connecting portion 20 is connected to the front side of the upper surface 11a of the upper wing plate 11 in the longitudinal direction, and the other end 22 is connected to the rear end side of the upper surface 11a in the longitudinal direction. The pull-tab connecting portion 20 includes: a locking member 29 that is a removable part constituting the other end 22 side portion of the pull-tab connecting portion 20; and a pull-tab connecting column 28 that is a portion other than the locking member 29, with the above one end 21 is a cantilever standing at the base end. The lock member 29 is fixed to a specific position shown in FIG. 1 and the like by engaging with the fixing portion 16 provided on the upper surface 11 a of the upper wing plate 11. The other end 22 of the pull-tab connecting portion 20 refers to the bottom of the locking member 29 that is in contact with the upper surface 11 a of the upper wing plate 11 in a state where the pull-tab 40 is connected to the pull-tab connecting portion 20.

The keyhole portion 30 stands higher than the upper surface 11a of the upper wing plate 11 in front of the tab connecting portion 20, and as shown in FIGS. 2 and 3, the left half of the width direction of the tab connecting portion 20 faces forward (FIG. 3). Upper middle) expands beyond the front end of the slider body 10 (hereinafter, also referred to as the "front end of the body") 10a. The portion of the keyhole portion 30 protruding forward from the front end 10a of the main body is semicircular. Reference numeral T1 in FIG. 1 and the like indicates that the highest end of the pull-tab connecting portion 20 from the upper surface 11a of the upper wing plate 11 is the first top end of the connecting portion. The keyhole portion 30 is expanded from the first tip T1 toward the front of the pull tab connecting portion 20. Hereinafter, the height refers to the height from the upper surface 11 a of the upper wing plate 11. There is no difference between the left and right halves from the other end 22 to the first tip T1 in the pull tab connecting portion 20, but from the first tip T1 to the rear, the left half is connected to the keyhole 30 and the right half is downward It bends in a curved shape and reaches one end 21. The pull-tab connecting portion 20 including the latching member 29 has a first outer side surface S1, which gradually increases toward the outer side as the height from the other end 22 to the first top end T1 (the so-called outer side means the The opposite side of the sheet connection hole 20a) is convexly curved. The first outer surface S1 is most protruded to the outside at an intermediate point in the width direction (the intermediate point between the left and right halves of the pull-tab connecting portion 20), and the degree of the outward protrusion is two to the left and right in the width direction from the intermediate point in the width direction. Sides that gradually become smaller. Therefore, in the side view of FIG. 1, the middle point in the width direction that protrudes most outward in the first outer side surface S1 is presented as an outline.

The reference symbol T2 in FIG. 1 and the like indicates that the highest end of the keyhole portion 30 is the second top end serving as the top end of the keyhole portion. The second tip T2 is located at substantially the same position as the main body tip 10a in the longitudinal direction. In addition, the second tip T2 is substantially located on an extension line of the diameter of the circular keyhole 30a along the vertical (up and down) direction. The keyhole portion 30 includes a second outer surface S2, which serves as an outer surface, and reaches the second top T2 from the first tip T1; and a curved outer surface 30b, which moves forward and downward from the second tip T2, and then downwards and rearwardly. It is curved in an arc shape, and finally ends at the front end of the upper surface 11 a of the upper wing plate 11. The keyhole portion 30 further includes right side surfaces 32a and left side surfaces 32b which are parallel to each other, and the second outer side surface S2 and the curved outer side surface 30b are connected along the width direction between the outer side edges of the right left surfaces 32a and 32b. The right and left sides 32a and 32b are perpendicular to the upper surface 11a of the upper wing panel 11, and are also approximately perpendicular to the second outer surface S2 and the curved outer surface 30b. The second outer surface S2 extends so as to gradually increase in height from the first tip T1 to the second tip T2. The width in the width direction of the second outer side surface S2 is a half of the width of the tab connecting portion 20. The second outer side surface S2 has substantially the same height as the right and left ends in the width direction, but the right end is slightly higher. Therefore, in the side view of FIG. 1, the right end of the second outer side surface S2 is presented as an outline. The first outer surface S1 and the second outer surface S2 are smoothly connected. Therefore, the first and second outer side surfaces S1 and S2 are smoothly connected from the other end 22 of the pull tab connection portion 20 to the second top end T2 of the keyhole portion 30, and the height gradually increases. In this embodiment, the difference between the height of the first tip T1 and the second tip T2 that is higher than the first tip T1 is 1 mm or less. Therefore, the second outer side surface S2 extending between the first and second top ends T1 and T2 is a substantially flat surface facing upward, and such a second outer side surface S2 can be said to be close to a horizontal plane. Such a flat second outer side surface S2 can withstand impact on a surface, and therefore has high impact resistance. In particular, in a state where the two sliders 1 are docked as described below (see FIGS. 5 and 6), on the upper surfaces of the respective keyhole portions 30 which overlap in the width direction, the respective substantially flat second portions The outer side surface S2 also overlaps in the width direction. Therefore, the second outer side surface S2 that overlaps in the width direction has high impact resistance, which helps protect against the impact of the keyhole portion 30.

Referring to FIG. 1, the closing member 29 constitutes a portion on the other end 22 side of the pull tab connecting portion 20. The other end side outer side surface S3 including the other end 22 side portion of the locking member 29 of the pull tab connection portion 20 stands at an angle θ with respect to the upper surface 11 a of the upper wing plate 11. The angle θ is 55 degrees to 65 degrees, and in this embodiment, it is about 60 degrees. The other end side outer side surface S3 is a part of the first outer side surface S1 and includes the outer side surface of the lock member 29. In this embodiment, the horizontal line (refer to the dotted line) extending from the upper end 20aa of the connecting hole 20a that is the highest (far) from the upper surface 11a to the rear (left of the paper surface in FIG. 1) and the outline of the connecting portion 20 The intersection point T3 is the upper end T3 of the outer surface S3 on the other end side. The contour of the outer surface S3 on the other end side extends substantially linearly to the upper end T3. In addition, whether the angle of the outer surface S3 on the other end side is within the aforementioned 55 degrees to 65 degrees or out of this range, it is preferable from the appearance point of view to set the following conditions. That is, if the length in the longitudinal direction of the slider body 10 is set to d1, and the other end 22 of the above-mentioned T3 and the pull-tab connecting portion 20 (strictly speaking, the rearmost and lowest end 22 of the lock member 29) The interval in the longitudinal direction (the interval in the longitudinal direction between the intersection of the lead straight line shown by the horizontal line drawn from the upper end 20aa of the connecting hole and the dotted line at the end 22 and the end line T3) is preferably d2. d2 / d1 is 5% to 15%. In this embodiment, it is about 12%. In this way, the other end 22 side of the pull-tab connecting portion 20 is raised from the upper surface 11a at about 60 degrees. As an example, d2 / d1 is set to about 12%, so that it can be placed below the two sliders 1. In the docking state (refer to FIG. 5), the contours formed by the first and second outer surfaces S1 and S2 of the pull-down tab connecting portion 20 and the keyhole portion 30 become a standard bow shape.

The sliders 1 described above can be installed in pairs of two, with the front ends 10a of the respective bodies facing each other, in opposite directions along the longitudinal direction, with respect to the shared zipper chain. 5 and 6 show a state in which the two sliders 1 are mounted on a common zipper chain (not shown) in a direction opposite to each other in the length direction, and the front ends 10a of the respective bodies are connected (hereinafter, referred to as a "docking state" ”) 'S side and top views. The sliders 1 are designed such that, in a docked state, the locking holes 30 a of the locking hole portions 30 of each slider 1 overlap in the width direction. Moreover, in the docked state, the right side surfaces 32a of the respective keyhole portions 30 face each other. If a padlock (not shown) or the like is locked in the locked hole 30a in the docked state, it becomes difficult to move the two sliders 1 in the direction of pulling apart from each other in the zipper chain, so that the zipper chain cannot be opened. In the docked state, the second top end T2 of the two sliders 1 overlaps in the width direction, and the second outer side surface S2 of the two sliders 1 also partially overlaps in the width direction. As shown in FIG. 5, when the two sliders 1 in a docked state are viewed from the side (one direction in the width direction), the first and second outer side surfaces S1 and S1 of the pull-tab connecting portion 20 and the keyhole portion 30 are observed. The outline defined by S2 is as follows. That is, in the first outer surface S1 of the slider 1 (for example, on the left side of the paper surface in FIG. 5), the contour gradually becomes higher as it curves outward from the other end 22 toward T1, and then moves toward the above-mentioned one slider. The second outer side surface S2 of 1 is connected to it gently, and in this second outer side surface S2, the outline becomes slightly higher as it goes toward the second tip T2. Then, the contour is gently connected to the second outer surface S2 of the other slider 1 (for example, on the right side of the paper surface in FIG. 5), and in the second outer surface S2, as it goes toward the first vertex T1 of the other slider 1, It gradually becomes lower gradually, and then gradually connects to the first outer side surface S1 of the other sliding member 1. In the first outer side surface S1, the curved shape that is convex outward becomes gradually lower, and finally reaches the other One sliding piece 1 at the other end 22. In this way, the first and second outer surfaces S1 and S2 of the pull-tab connecting portion 20 and the keyhole portion 30 of the two sliders 1 in the docked state are viewed from the side to define the contour of the arcuate shape (refer to FIG. 5). Both ends of the profile system are in contact with the upper surface 11a of the upper wing plate 11 without a gap, and there is no part protruding outward or forming a concave portion inward. Therefore, for example, in the case where the above two slides 1 are used as a zipper of a travel bag, even if the travel bag touches a wall or a floor, it will not be locally and locally impacted, and the pull-tab connecting portion 20 and the keyhole portion The possibility of deformation or the like of the 30 or the slider body 10 is reduced. In the slider 1 of this embodiment, the difference between the height of the first tip T1 and the second tip T2 is, for example, about 1 mm or less, which is small. Therefore, in the docking state (see FIG. 5), the second tip T2 The second outer side surface S2 extending between the respective first tips T1 of the two sliders 1 placed in the middle in the longitudinal direction becomes a substantially flat surface facing upward. This kind of surface can bear the impact when it touches the wall or floor, so it has high impact resistance.

FIG. 7 is a side view similar to FIG. 5 in which the sliders 2 of the second embodiment of the present invention are mounted in a pair of two on a common zipper (not shown), and are formed in a docking state. In addition, the slider body 10 including the upper wing plate 11 and the like is substantially the same as the slider 1 described above, and therefore the same reference numerals are assigned and description thereof is omitted. Each slider 2 is provided on the upper surface 11 a of the slider body 10 and includes a pull-tab connecting portion 50 and a removable key hole portion 60 defining a circular key hole 60 a. The pull-tab connection portion 50 includes a cantilever-shaped pull-tab connection post 58 and a rear portion 69 of the keyhole portion 60. In other words, the rear portion 69 can be said to be a part of the pull-tab connecting portion 50. In the slider 2, by installing the lock hole portion 60 at a specific position, the free end of the pull-tab connecting post 58 and the upper surface 11 a are filled, and the pull-tab connecting hole 50 a is closed. Thereby, the pull tab connection part 50 is completed. Therefore, the lower end which is in contact with the upper surface 11 a of the rear portion 69 of the keyhole portion 60 becomes the one end 51 of the guide rod side in the longitudinal direction of the pull tab connecting portion 50, and the base end 52 of the pull tab connecting post 58 becomes the pull tab connecting portion 50. Of the other end 52.

In FIG. 7, the reference symbol T11 is the highest first tip of the pull-tab connection post 58, and the reference symbol T12 is the highest second tip of the keyhole portion 60. The second tip T12 is located at substantially the same position as the front end of the body in the longitudinal direction. The pull-tab connection post 58 has a first outer side surface S11 that gradually increases in height from the base end 52 to the first tip T11 and is convexly curved outward. In addition, the keyhole portion 60 includes a second outer surface S12 that reaches the second distal end T12 from the first distal end T11. The second outer surface S12 extends so as to gradually increase in height from the first tip T11 to the second tip T12. Since the first outer surface S11 and the second outer surface S12 are substantially smoothly connected, the first and second outer surfaces S11 and S12 are convexly curved surfaces that extend from the other end 52 of the pull-tab connecting portion 50 to the keyhole The second tip T12 of the portion 60 is smoothly connected, and the height gradually increases. In this way, the first and second outer sides S11 and S12 of the pull-tab connecting portion 50 and the keyhole portion 60 of the two sliders 2 in the docked state are viewed from the side to define an arcuate shape.
