Description

Technical Field

[0001] The invention relates to a slider for a zipper. Background Art

[0002] As a conventional slider for a slide fastener, the slider described in Patent Document 1 is known. Figures 4 to 7 The pull tab (symbol 10) includes a pulling portion (symbol 11) and a gripping portion (symbol 12). The pulling portion is provided with a pulling hole (symbol 111), and the three sides of the pulling hole are along a connecting rod (symbol 112) arranged at the front end and two side supports (symbol 113) arranged on the side.

[0003] Furthermore, the thickness of the connecting rod (112) and the two side struts (113) is set to be greater than the thickness of the groove (23) between the flange of the upper wing plate (21) and the flange of the lower wing plate (22). This prevents the two side struts (113) of the pull tab (10) of one slider from being inserted into and caught in the groove (23) of the slider body (20) of another slider.

[0052] Hereinafter, the slider for slide fasteners which concerns on embodiment of this invention is demonstrated in detail based on drawings. Hereinafter, the slider for slide fasteners may be called "slider".

[0053] In addition, in this specification, with respect to the slider, "up and down direction" refers to the sliding direction of the slider, and refers to the length direction of the zipper not shown in the figure, and in particular, the direction in which the slider slides so as to engage the left and right rows of chain teeth is set as "upward", and the direction in which the slider slides so as to separate the left and right rows of chain teeth is set as "downward".

[0054] In addition, regarding the slider, the "left-right direction" refers to the direction in which a pair of fastener element rows are arranged, is a direction perpendicular to the sliding direction of the slider, and may also be referred to as the width direction of the slider.

[0055] Furthermore, for a slider, the "front-back direction" refers to a direction perpendicular to the up-down direction and the left-right direction, and is the height (thickness) direction of the slider, and may also be referred to as the thickness direction of the fastener fabric (not shown) or the height direction of the fastener element row.

[0056] Specifically, the user moves the slider 1 upward (see Figures 1 to 3 ), and the sprocket rows of the left and right zipper chains are engaged, and the user disengages the sprocket by moving the slider 1 downward. Like this, the up-down direction is the sliding direction of the slider 1, and is also the length direction of the zipper cloth. The left-right direction (width direction) is a direction parallel to the front wing plate 11 and the back wing plate 16 of the main body 10 of the slider 1 described below and perpendicular to the up-down direction. In addition, the front-back direction is a direction perpendicular to the front wing plate 11 and the back wing plate 16.

[0057] Figure 1 This is a diagram of the slider viewed from the front. Figure 2 This is a diagram of the slider viewed from the back side. Figure 3 This is a diagram obtained by observing the slider from the left and right directions. Figure 4 yes Figure 1 Arrow view of IV-IV section.

[0058] Figures 1 to 4The slider 1 shown forms part of a zipper (not shown) and is used to engage and disengage the sprocket teeth of a pair of left and right zipper chains. A zipper chain, for example, comprises a woven zipper fabric extending in the longitudinal direction, and a sprocket tooth row made of metal or thermoplastic resin, attached to the widthwise inner edge of the zipper fabric. Alternatively, the zipper chain may comprise a continuous zipper tooth sewn into the zipper fabric, made of thermoplastic resin, and formed in a loop or zigzag pattern.

[0059] like Figures 1 to 4 As shown, the slider 1 includes a main body 10 and a pull tab 30 mounted on the main body 10. Figure 4 As described above, the slider 1 of this embodiment is a slider with an automatic stop function.

[0060] The main body 10 includes a front wing 11 and a back wing 16, which are arranged parallel to each other in the front-to-back direction, and a guide post 19 connecting the upper end of the front wing 11 and the upper end of the back wing 16 in the front-to-back direction. The front wing 11 includes a front flange 12, which projects from both widthwise edges of the front wing 11 toward the back side, and a tab mounting portion 20, which has a tab mounting hole 21 for mounting a tab 30 and is provided on the front face of the front wing 11. The back wing 16 includes a back flange 17, which projects from both widthwise edges of the back wing 16 toward the front side and faces the front flange 12 in the front-to-back direction.

[0061] Thus, a pair of left and right introduction ports 13, 13 separated by guide posts 19 are formed in the upper portion of the main body 10, and an engagement port 14 is formed in the lower portion of the main body 10. Furthermore, a substantially Y-shaped element guide path 15 is formed between the front flap 11 and the back flap 16, connecting the pair of left and right introduction ports 13, 13 on the upper side with the engagement port 14 on the lower side. This element guide path 15 constitutes a passage through which a zipper element row (not shown) is inserted.

[0062] like Figure 4 As shown, the pull-tab mounting portion 20 includes an upper mounting post 22 and a lower mounting post 23, which are respectively erected on the upper and lower portions of the front surface of the front wing panel 11; and a cover portion 24, which is arranged so as to straddle the upper mounting post 22 and the lower mounting post 23. Furthermore, the stopper 25, the shaft portion 33 of the pull-tab 30, and the leaf spring 26 are housed between the upper mounting post 22 and the lower mounting post 23.

[0063] The upper mounting post 22 and the lower mounting post 23 are covered with a cover 24 and fixed by pressing. In addition, a claw insertion hole 11a is formed on the front wing plate 11 for inserting the head end 25a of the stop claw 25. The head end 25a of the stop claw 25 inserted into the claw insertion hole 11a reaches the chain tooth guide path 15 and is inserted between the zipper teeth (not shown) to limit the movement of the slider 1. The leaf spring 26 arranged on the front side of the stop claw 25 is in the shape of a roughly rectangular plate extending in the vertical direction and is fixed to the upper and lower locking portions (not shown) formed on the back side of the cover 24. In this way, the pull tab mounting portion 20 of this embodiment includes the upper mounting post 22, the lower mounting post 23, the cover 24, the stop claw 25, and the leaf spring 26.

[0064] Figure 5 This is a diagram of the pull-tab viewed from the front side. Figure 6 This is a picture of the pull tab viewed from the back. Figures 1 to 6 The handle 30 will be described.

[0065] The pull tab 30 is a long plate-shaped member, such as Figure 5 and Figure 6 As shown in the figure, it is symmetrical in both directions. Figure 5 The shape of the pull-tab 30 as viewed from the front side is similar to that of Figure 6 The shape of the pull tab 30 as viewed from the back is the same as shown. However, the pull tab 30 does not necessarily need to be symmetrical. The pull tab 30 includes a first portion 30A on the base end side of the shaft portion 33 formed therein for mounting in the pull tab mounting hole 21 of the pull tab mounting portion 20, and a second portion 30B on the opposite side of the first portion 30A in the longitudinal direction of the pull tab 30.

[0066] The second portion 30B is typically grasped by the user. A convex portion 32 protruding in the front-to-back direction is formed in the portion of the second portion 30B that constitutes the tip of the pull tab 30. Furthermore, a through-hole 34 extending through the pull tab 30 in the front-to-back direction is formed in the portion of the second portion 30B adjacent to the convex portion 32 in the longitudinal direction. A plate-shaped portion 36 is formed in the portion adjacent to the through-hole 34 in the longitudinal direction. The user can pull the pull tab 30 by, for example, pinching the plate-shaped portion 36 with their fingers or inserting their fingers into the through-hole 34 and hooking them onto the convex portion 32.

[0067] An opening 31 is formed in the first portion 30A at a portion adjacent to the plate-shaped portion 36 in the longitudinal direction, penetrating the pull tab 30 in the front-back direction. The opening 31 is a portion for attaching the pull tab 30 to the pull tab mounting portion 20, and the lower portion of the cover portion 24 constituting the pull tab mounting portion 20 is inserted through the opening 31.

[0068] Furthermore, a shaft portion 33 extending in the width direction of the pull tab 30 is provided at a portion of the first portion 30A adjacent to the opening 31 in the longitudinal direction. The shaft portion 33 constitutes the base end portion of the pull tab 30 and is inserted into the pull tab mounting hole 21 of the pull tab mounting portion 20 and mounted on the body 10.

[0069] The pull tab 30 has ribs 40 formed from the outer periphery of the front and back sides toward the front and back sides of the pull tab 30. The ribs 40 of this embodiment are formed on both the front and back sides, but it is sufficient to form them on at least one of the front and back sides. The front and back direction dimension L1 of the portion of the pull tab 30 where the ribs 40 are formed (see Figure 3 ) is larger than the front-back dimension of the plate-shaped portion 36 and the shaft portion 33. By providing such a rib 40, the strength of the pull-tab 30 can be improved, and the user can easily hook his fingers on the rib 40 and grasp the pull-tab 30. In addition, the front-back dimension L1 of the portion of the pull-tab 30 where the rib 40 is formed is set larger than the front-back dimension L2 between the front-side flange 12 and the back-side flange 17 (refer to FIG. Figure 3 Thus, as described below, it is possible to prevent the tab 30 of one slider 1 from being stuck inside the main body 10 of another slider 1.

[0070] The rib 40 includes a peripheral rib 41 formed on the outer periphery of the portion of the pull-tab 30 excluding the shaft portion 33. Both ends 41a, 41a of the peripheral rib 41 on the shaft portion 33 side (the base end side of the pull-tab 30) are located opposite to the opening 31 in the width direction of the pull-tab 30. In other words, Figure 5 and Figure 6 As shown, the two end portions 41a, 41a of the peripheral rib 41 are located in a region S, which is a region between a plane P1 obtained by extending the end portion on the head end side of the opening 31 in the width direction and a plane P2 obtained by extending the end portion on the base end side of the opening 31 in the width direction.

[0071] The peripheral rib 41 extends from both ends 41a, 41a along the outer periphery of the rib 40 toward the tip of the pull tab 30 and meets at the tip of the pull tab 30 where the protrusion 32 is formed. The peripheral rib 41 covers the opening 31, the plate-like portion 36, and the through-hole 34 from the outer periphery.

[0072] The rib 40 includes an extension portion 43 that extends from both ends 41a, 41a of the outer peripheral rib 41 toward the opening 31, i.e., inward in the width direction. In this embodiment, the extension portion 43 is connected to the end 41a of the outer peripheral rib 41 and extends in the width direction. However, the location where the extension portion 43 is connected is not limited to the end 41a of the outer peripheral rib 41. The extension portion 43 only needs to be connected to the portion of the outer peripheral rib 41 that faces the opening 31 in the width direction, i.e., the portion located within the region S.

[0073] The extension portion 43 of this embodiment is an inclined rib that is inclined so as to approach the shaft portion 33 on the base end side as it goes to the inner side in the width direction. Figure 3 As shown, when the pull tab 30 is tilted, the end portion 43a of the extension portion 43 on the side of the shaft portion 33 can be brought into point contact with the front surface of the front wing plate 11. By reducing the contact area between the extension portion 43 and the front wing plate 11, the surface treatment material can be supplied to the entire surface of the slider 1 during surface treatment such as painting.

[0074] In addition, the extension portion 43 does not necessarily have to be an inclined rib. As long as it extends inward in the width direction, it can be any shape. For example, it can be a straight rib that does not incline toward the shaft portion 33 side of the rib 40 but extends straightly inward in the width direction.

[0075] The extension portion 43 preferably extends inward in the width direction and reaches the opening 31. In other words, the inner end of the extension portion 43 in the width direction is preferably connected to the opening 31. This can more reliably prevent the tab 30 of one slider 1 from being caught in the body 10 of the other slider 1, as described below.

[0076] The extension portion 43 is located in the region S and is formed at a position that does not overlap with the shaft portion 33. Therefore, the rib 40 is not formed on the shaft portion 33. Therefore, the shaft portion 33 installed in the pull-tab installation hole 21 does not become thicker due to the rib 40. Figure 3 As shown, the rising angle θ when the pull tab 30 is tilted can be kept small. Furthermore, the rising angle θ is the angle between the front surface of the front wing 11 and the back surface of the pull tab 30. This rising angle θ is preferably 5° or less, more preferably 4° or less, and even more preferably 3° or less. By reducing the rising angle θ, the slider 1 exhibits excellent aesthetics when the pull tab 30 is tilted.

[0077] The slider 1 having the above-described structure is subjected to surface treatment in a state where the main body 10 and the pull tab 30 are combined. The types and combinations of surface treatments vary and can be appropriately determined by the industry. For example, the surface treatment may include plating (electroplating, electroless plating, etc.), chemical synthesis treatment (chromate treatment, phosphate coating treatment, blackening treatment, etc.), painting, or any combination thereof.

[0078] In particular, in the coating process, a roller coating method is sometimes used. The roller coating method is to accommodate multiple sliders 1 in a roller, and spray paint on the roller while rotating the roller to form a coating film. In this case, in order to evenly form a coating film on the entire slider 1, it is preferred that the multiple sliders 1 move individually in the roller. It is important not to form a state in which multiple sliders 1 are combined with each other. When the sliders 1 are combined with each other, there are parts that contact each other, so the paint will not be supplied to this part, resulting in uneven coating. Sliders 1 with uneven coating need to be removed as defective products during the full inspection after surface treatment.

[0079] Here, as a comparative example in which sliders can be combined with each other, a handle 300 of a slider in which the extending portion 43 is not provided will be described. Figure 7 This is a diagram of a pull-tab of a comparative example viewed from the front side. Figure 8 This is a picture obtained by observing the pull-tab of the comparative example from the back side. Figure 7 and Figure 8 As shown, the pull tab 300 of the comparative example is similar to the pull tab 300 except that the extension portion 43 is not formed. Figure 5 and Figure 6 The pull tabs 30 of the illustrated embodiments are generally identical.

[0080] Figure 9 This is a diagram showing a state in which the main body of one slider is inserted from the introduction port side into the tab of the other slider in a comparative example. Figure 10 It means from Figure 9 A diagram showing the progress of the card insertion from the current state. Figure 11 This is a diagram showing a state in which the main body of one slider is engaged with the tab of the other slider from the meshing opening side in a comparative example.

[0081] like Figures 9 to 11 As shown in FIG. 1 , one slider 100 having a pull tab 300 of the comparative example does not have an extension portion 43 formed on the pull tab 300. Therefore, the space between the two end portions 41a, 41a of the peripheral rib 41 and the opening 31 is open, and the body 10 of the other slider 100 enters the open space. The widthwise edge portion of the body 10 of the other slider 100, where the front flange 12 and the back flange 17 are provided, passes between the end portions 41a of the peripheral rib 41 of the one slider 100 and the opening 31, as shown in FIG. Figure 10 As shown, it is completely inserted into the pull tab 30. Figure 10 In the state shown, when the roller rotates during roller painting, it is difficult for the pull-tab 300 and the main body 10 to be naturally eliminated.

[0082] Figure 12 It means Figure 9 FIG. 1 is a diagram showing a case where the handle of the comparative example is replaced with the handle of the present embodiment. Figure 13 It means Figure 11FIG. 1 is a diagram showing a case where the handle of the comparative example is replaced with the handle of the present embodiment.

[0083] also, Figure 12 and Figure 13 The position of the pull tab 30 of the present embodiment is drawn to correspond to Figure 9 and Figure 11 The position of the pull-tab 300 of the comparative example shown is substantially the same, and therefore, the extension portion 43 of the rib 40 of the pull-tab 30 is arranged in a manner overlapping the front flange 12 and the back flange 17 of the main body 10. However, in reality, Figure 12 and Figure 13 Before the state shown, the front flange 12 and the back flange 17 of the main body 10 are prevented from entering the head end side of the pull tab 30 by the extension portion 43 ( Figure 12 and Figure 13 The reason is that the front-back dimension L1 of the portion of the pull tab 30 where the rib 40 (extension 43) is provided is larger than the front-back dimension L2 between the front flange 12 and the back flange 17 (refer to Figure 3 ).

[0084] In addition, as described above, the extension portion 43 extends inward in the width direction in a manner connected to the opening 31, and the distance L3 between the head end of the extension portion 43 and the cover portion 24 is made smaller than the width direction dimension L4 of the front flange 12 and the back flange 17. This prevents the main body 10 from passing through the path between the head end of the extension portion 43 and the cover portion 24. In addition, the distance L3 between the head end of the extension portion 43 and the cover portion 24 varies depending on the inclination of the pull-tab 30 relative to the cover portion 24, etc. Figure 12 and Figure 13 FIG shows a state in which the pull tab 30 is tilted to the maximum with respect to the cover 24 so that the distance between the head end of the extension 43 and the cover 24 is maximized. Figure 12 and Figure 13 As shown, in the state where the distance L3 is the largest, the shape of the extending portion 43 is also set to satisfy L3<L4.

[0085] In addition, the present invention is not limited to the contents illustrated in the above embodiment and can be appropriately modified within the scope of the present invention. For example, in the above embodiment, a slider 1 with an automatic stop function is illustrated, but it is not limited to this and a slider 1 without an automatic stop function can also be used.

[0086] As described above, the following matters are disclosed in this specification.

[0087] [1] A slider for a zipper (1), comprising:

[0088] Subject (10); and

[0089] A pull tab (30) mounted on the main body (10);

[0090] The main body (10) comprises:

[0091] Front wing panel (11);

[0092] rear wing panel (16); and

[0093] A guide column (19) connects the front wing plate (11) and the back wing plate (16) in the front-to-back direction;

[0094] The front wing panel (11) has:

[0095] A front flange (12) is provided protruding from both edges in the width direction of the front wing plate (11) toward the back side; and

[0096] A pull tab mounting portion (20) has a pull tab mounting hole (21) for mounting the pull tab (30) and is arranged on the front side of the front wing plate (11);

[0097] The back wing plate (16) has a back side flange (17), and the back side flange (17) is protruded from both edges in the width direction of the back wing plate (16) toward the front side and faces the front side flange (12) in the front-back direction.

[0098] The pull tab (30) has:

[0099] an opening (31) passing through the pull tab (30) and used for installing the pull tab (30) on the pull tab installation portion (20);

[0100] A shaft portion (33) is formed at an end portion of the pull tab (30) adjacent to the opening (31) and is mounted in the pull tab mounting hole (21) of the pull tab mounting portion (20); and

[0101] A rib (40) is formed from the outer periphery of at least one of the front and back sides of the pull tab (30) toward the front and back sides of the pull tab (30);

[0102] The front-back dimension (L1) of the portion of the pull tab (30) where the rib (40) is provided is larger than the front-back dimension (L2) between the front flange (12) and the back flange (17), and

[0103] The rib (40) has an extension portion (43) extending inward in the width direction from a portion facing the opening (31) in the width direction.

[0104] According to this structure, since the rib has the extension part, it is possible to prevent the pull tab of one slider from being caught in the interior of the main body of another slider. Therefore, the surface treatment of the slider can be uniformly performed.

[0105] Furthermore, the rib extension extends inward in the width direction from the portion opposite the pull-tab mounting hole in the width direction. This eliminates the need to thicken the shaft portion mounted in the pull-tab mounting hole, and reduces the rising angle when the pull-tab is tilted, resulting in excellent design.

[0106] [2] The slider for a slide fastener (1) according to [1], wherein

[0107] The extension portion (43) extends from an end portion (41a) of the rib (40) on the shaft portion (33) side toward the inside in the width direction.

[0108] According to this configuration, since the extending portion is arranged on the side close to the shaft portion, it is possible to effectively prevent the handle from being caught in the interior of the main body.

[0109] [3] The slider for a slide fastener (1) according to [1] or [2], wherein

[0110] The extension portion (43) is an inclined rib (43) that is inclined so as to approach the shaft portion (33) as it moves toward the inner side in the width direction.

[0111] According to this configuration, the extension portion is an inclined rib, so the end portion of the extension portion on the axis side can be brought into point contact with the front surface of the front wing panel. This reduces the contact area between the extension portion and the front wing panel surface, thereby increasing the space available for materials such as paint to penetrate during surface treatment, thereby enabling appropriate painting.

[0112] [4] The slider for a slide fastener (1) according to any one of [1] to [3], wherein

[0113] The extension portion (43) extends to the opening (31).

[0114] According to this structure, the handle of one slider can be prevented from being caught in the inside of the main body of the other slider more reliably.
