Fig. 13 is a schematic end view of a slide fastener, illustrating a half of cross-section along XII-XII shown in Fig. 11.

[0017] As shown in Figs. 1 and 2, a slide fastener 700 has a left-right pair of fastener stringers 400 and a slider 500 for opening and closing the left-right paired fastener stringers 400. Each fastener stringer 400 may have a fastener tape 100, fastener elements 200 provided along a side edge 150 of the fastener tape 100, and a resin-made front stop 300 provided at the side edge 150 of the fastener tape 100, and a metal-made or resin-made rear stop 600 provided at the side edge 150 of the fastener tape 100. The rear stop 600 may be common between the left and right fastener stringers 400, whereby the left and right fastener stringers 400 being coupled at the rear end side.

[0018] As shown in Fig. 11 and 12, the slider 500 may have a top wing 510, a bottom wing 520, a guide column 530, a flange portion 540, a pull-attachment column 550, and a pull 560. The top wing 510 and the bottom wing 520 are coupled via the guide column 530, and the top wing 510 and the bottom wing 520 are arranged in parallel one another. The shape of the top wing 510 viewed from above and the shape of the bottom wing 520 viewed from below may be identical. Y-shaped element path for the fastener elements 200 may be defined by the top wing 510, the bottom wing 520, the guide column 530, and the flange portion 540. The flange portion 540 may include top flange portions extending downward from left or right side edge of the top wing 510, and bottom flange portions extending upward from left or right side edge of the bottom wing 520. In some embodiments, one of the top flange portion and the bottom flange portion may be omitted. The pull-attachment column 550 may be provided as a cantilever on the top surface of the top wing 510. The pull may have a hole through which the pull-attachment column 550 is inserted.

[0019] Each fastener tape 100 may have a first region 110 where the fastener elements 200 are not provided at the side edge 150, a second region 120 where the fastener elements 200 are provided at the side edge 150, and a third region 130 where the front stop 300 is provided at the side edge 150. The third region 130 is provided between the first region 110 and the second region 120. That is, each front stop 300 is provided between the first region 110 where the fastener elements 200 are not provided at the side edge 150 and the second region 120 where the fastener elements 200 are provided at the side edge 150.

[0020] It is envisaged that each first region 110 of the fastener tape 100 may be useful for firmly sewing the slide fastener 700 onto other articles. Fig. 2 illustrates a condition where the left and right fastener stringers 400 are coupled to be a Y-shape, and an interspace W110 is caused between the left and right first regions 110. It is envisaged that this interspace W110 between the left and right first regions 110 may be reduced by employing the front stops 300 according to the present embodiment. It should be noted that the front-back lengths of the first regions 110 of the respective fastener tapes 100 are not necessarily the same. The front-back lengths of the second regions 120 of the respective fastener tapes 100 could be varied in various embodiments.

[0021] Each fastener tape 100 may be a cloth made from woven yarns or a knit fabric made from knitted yarns. Each fastener tape 100 may be a flexible member having a pair of tape surfaces as a top surface and a bottom surface. Each fastener tape 100 may include a tape main portion 140 and a side edge 150 provided at the hem of the tape main portion 140. The side edge 150 of each fastener tape 100 may be opposed to the side edge 150 of the other left or right fastener tape 100, and thus this may sometimes be referred to as an opposed side edge. In some embodiments, the side edge 150 includes a portion thicker than the tape main portion 140 and, in some embodiments, the side edge 150 includes a core thread 155, not necessarily limited to though.

[0022] A direction directed to the inner side of the fastener tape 100 may be referred to as inward(ly) of the fastener tape, i.e. inward(ly) of tape. A direction directed to the outer side of the fastener tape 100 may be referred to as outward(ly) of the fastener tape, i.e. outward(ly) of tape. As a comprehensive example, the direction of inward(ly) of tape may be a direction directed from a point positioned external to the tape surface of the fastener tape 100 toward a point positioned over the tape surface of the fastener tape 100 while crossing the side edge of the fastener tape. The direction of outward(ly) of tape may be a direction directed from a point positioned over the tape surface of the fastener tape 100 toward a point positioned external to the tape surface of the fastener tape 100 while crossing the side edge of the fastener tape. The directions indicated by the terms of inward(ly) of tape and outward(ly) of tape may be applicable for a region inside the tape surface of the fastener tape.

[0023] The fastener elements 200 are provided at the side edge 150 of the fastener tape 100. A coil element is illustrated as a fastener element 200, but it should not be limited thereto. In some embodiments, resin elements or metal elements may be employed as a fastener element. It will be understood that the benefit of the present disclosed embodiment will be appreciated regardless of types of fastener element.

[0024] The fastener element 200 may have an engaging portion 210 and a base 220. The engaging portion 210 is a portion that can engage with the other one of the paired fastener elements 200. The base 220 is positioned inwardly of tape relative to the engaging portion 210 of the fastener element 200, and is a portion for ensuring attachment of the fastener element 200 to the fastener tape 100. As would be understood by a skilled person, the engaging portions 210 are contactable with the guide column 530 of the slider 500, and the bases 220 are contactable with the flange portion 540 of the slider 500.

[0025] The illustrated exemplary fastener element 200 is a coil element, and is configured from a helically wound monofilament. The fastener element 200 is configured by a series of fundamental units in the front-rear direction. Each fundamental unit may include an engaging head 231 configured wider in the front-rear direction, a top leg 232 coupled to the top end of the engaging head 231, a bottom leg 233 coupled to the bottom end of the engaging head 231, and a return portion 234 coupled to the other end of a bottom leg 233 and to the other end of a top leg of an adjacent fundamental unit. The engaging head 231 is not provided over the side edge 150 of the fastener tape 100. The top leg 232 and the bottom leg 233 extend inwardly of tape while traversing the core thread 155 at the side edge 150 of the fastener tape 100.

[0026] The width W200 of the fastener element 200 may be defined by the first imaginary plane PL1 and the second imaginary plane PL2 which are in parallel one another. As shown in Figs. 3 and 6, points or surfaces of the respective engaging portions 210 at the outer-most position outwardly of the fastener tape are arranged in the first imaginary plane PL1. Points or surfaces of the respective bases 220 at the inner-most position inwardly of the fastener tape are arranged in coplanar fashion in the second imaginary plane PL2.

[0027] In other words, points or surfaces of the respective engaging portion 210 positioned farthest from the side edge 150 of the fastener tape 100 are arranged in the first imaginary plane PL1. Points or surfaces of the respective bases 220 positioned farthest from the respective engaging portions 210 are arranged in the second imaginary plane PL2.

[0028] In the illustrated exemplary coil element, the flat surfaces of the respective engaging portions 210 are arranged in the first imaginary plane PL1. Innermost points in the respective return portions 234 inwardly of the tape are arranged in the second imaginary plane PL2.

[0029] In a case where the slide fastener 700 is referenced as a premise, the first imaginary plane PL1 defines an inner boarder for the fastener elements 200 in the left and right direction. The second imaginary plane PL2 defines an outer boarder for the fastener elements 200 in the left and right direction.

[0030] Each front stop 300 may have a shape like a crescent when viewed from above. Each front stop 300 has a front surface 310 facing the first region 110, a rear surface 320 facing the second region 120, a first side surface 330 extending between the front surface 310 and the rear surface 320 and facing outwardly of the fastener tape, and a second side surface 340 extending between the front surface 310 and the rear surface 320 and facing inwardly of the fastener tape. Each front stop 300 has a top surface 350 provided away from the top tape surface 101 of the fastener tape 100 and a bottom surface 360 that is flush with the tape bottom surface 102 of the fastener tape 100. A rounded edge exists between the first side surface 330 and the front surface 310, and a rounded edge exists between the first side surface 330 and the rear surface 320.

[0031] In non-limited embodiments, each front stop 300 may be integrally molded to the side edge 150 of the fastener tape 100 through an insert molding. The front-rear length of the left-side front stop 300 may be greater than the front-rear length of the right-side front stop 300. The left-side front stop 300 extends along the side edge 150 of the fastener tape 100 longer than the right-side front stop 300.

[0032] A rear region of the first side surface 330 of the left-side front stop 300 shown in Fig. 3 is provided with a recessed engaging portion 390 recessed inwardly of the fastener tape beyond the first imaginary plane PL1. The recessed engaging portion 390 has a side surface 391 that crosses the first imaginary plane PL1.

[0033] A rear region of the first side surface 330 of the right-side front stop 300 shown in Fig. 6 is provided with a projected engaging portion 380 projected outwardly of the fastener tape beyond the first imaginary plane PL1. The projected engaging portion 380 has two side surfaces 381 that cross the first imaginary plane PL1.

[0034] When the left and right front stops 300 are housed in the slider as a result of frontward movement of the slider, the recessed engaging portion 390 of the left-side front stop 300 and the projected engaging portion 380 of the right-side front stop 300 are engaged or in contact one another, thereby clockwise rotational force being applied to the left-side front stop 300 and anticlockwise rotational force being applied to the right-side front stop 300. The second side surface 340 of each left or right front stop 300 includes, from the front region to the rear region thereof, a slant surface 345 extending and being sloped to be closer to the second imaginary plane PL2, allowing the rotation of each front stop 300 until the second side surfaces 340 of each front stop 300 touches the inner wall surface of the flange portion 540 of the slider 500.

[0035] It should be noted that front region and the rear region are determined relatively. For example, in the illustrated examples, the front region of the front stop 300 may be a region positioned frontward from the center of the front stop 300 in the front-rear direction. The rear region of the front stop 300 may be a region positioned rearward from the center of the front stop 300 in the front-rear direction. The front and rear regions can be redefined relative to a point shifted frontward or rearward from the center of the front stop 300 in the front-rear direction.

[0036] This rotation of each front stop 300 may reduce the interspace W110 shown in Fig. 2. The reduction of interspace W110 shown in Fig. 2 may improve the appearance of the slide fastener 700 under a closed state or may ensure easier sewing or may ensure improved initial movement of the slider 500. The initial movement of a slider may be equal to easiness of initial movement of a stopping slider.

[0037] As shown in Figs. 3 and 6, the illustrated exemplary front stop 300 each has a rounded first edge 371 between the front surface 310 and the second side surfaces 340 which is projected inwardly of tape beyond the second imaginary plane PL2. The first edge 371 is positioned inwardly of tape relative to the second side surfaces 340, and the second side surfaces 340 extends to be closer to the second imaginary plane PL2 as extending rearward. In the left-side front stop 300 illustrated in Fig. 3, the slant surface 345 of the second side surfaces 340 crosses the second imaginary plane PL2 while extending rearward. In this case, when an intersection between the slant surface 345 and the second imaginary plane PL2 is set, a frontward half of the slant surface 345 from the intersection is positioned inwardly of tape relative to the second imaginary plane PL2, and a rearward half of the slant surface 345 from the intersection is positioned outwardly of tape relative to the second imaginary plane PL2. In the right-side front stop 300 illustrated in Fig. 6, the slant surface 345 of the second side surfaces 340 does not cross the second imaginary plane PL2 while extending rearward. However, the slant surface 345 of the right-side front stop 300 may cross the second imaginary plane PL2 in other embodiments.

[0038]  The slant surface 345 of the second side surfaces 340 of the left-side front stop 300 illustrated in Fig. 3 is coupled to the rear surface 320 via a rounded second edge 376. The slant surface 345 of the second side surfaces 340 of the right-side front stop 300 illustrated in Fig. 6 is coupled to the rear surface 320 via a rounded second edge 376. The boarder 377 between the slant surface 345 of the second side surfaces 340 of the right-side front stop 300 and the second edge 376 may be located on the second imaginary plane PL2 or nearby the second imaginary plane PL2. The second edge 376 of the right-side front stop 300 may cross the second imaginary plane PL2.

[0039] As shown in Figs. 3 and 6, a front region of the first side surface 330 of each front stop 300 is provided with a rounded bulge 372 projected outwardly of tape. The bulge 372 is configured to be contactable with the guide column 530 of the slider 500. In the left-side front stop 300 illustrated in Fig. 3, the bulge 372 does not extend outwardly of tape beyond the first imaginary plane PL1, and the outer-most position of the bulge 372 outwardly of tape is located on the first imaginary plane PL1. In contrast, in the right-side front stop 300 illustrated in Fig. 6, the bulge 372 extends outwardly of tape beyond the first imaginary plane PL1. This may ensure that a space between the guide column 530 and the flange portion 540 of the slider is sufficiently closed.

[0040] The rear region of the first side surface 330 of each front stop 300 is provided with a projection projecting outwardly of tape beyond the first imaginary plane PL1. In the left-side front stop 300 illustrated in Fig. 3, the rear region of the first side surface 330 is provided with a projection 373, and the above-described recessed engaging portion 390 is provided adjacent to and at the front-side of the projection 373. The projection 373 projects outwardly of tape from the first imaginary plane PL1. A slant surface 375 is provided adjacent to and at the front-side of the recessed engaging portion 390. A recess 374 is provided adjacent to and at the front-side of the slant surface 375. The above-described bulge 372 is provided adjacent to and at the front-side of the recess 374.

[0041] In the right-side front stop 300 illustrated in Fig. 6, the rear region of the first side surface 330 is provided with the above-described projected engaging portion 380, and a slant surface 375 is provided adjacent to and at the front-side of the projected engaging portion 380. A recess 374 is provided adjacent to and at the front-side of the slant surface 375. The above-described bulge 372 is provided adjacent to and at the front-side of the recess 374.

[0042] The bulge 372 may close the mouth between the guide column 530 and the flange portion 540 of the slider 500. The bulge 372 is rounded when viewed from above, and thus small amount of contact drag between the bulge 372 and the guide column 530 may be achieved. The contact area between the first side surface 330 of the front stop 300 and the guide column 530 may be reduced by the recess 374. The stable displacement of the front stop 300 between the guide column 530 and the flange portion 540 may be achieved due to the slant surface 375.

[0043] The slant surface 375 of the first side surface 330 may be referred to as a first slant surface, and the slant surface 345 of the second side surfaces 340 may be referred to as a second slant surface; alternatively the slant surface 375 of the first side surface 330 may be referred to as a second slant surface, and the slant surface 345 of the second side surfaces 340 may be referred to as a first slant surface. In some embodiments, the first slant surface and the second slant surface are in parallel one another.

[0044] As shown in Figs. 4 and 7, each front stop 300 has a top surface 350 provided away from the top tape surface 101 of the fastener tape 100 and a bottom surface 360 that is flush with the tape bottom surface 102 of the fastener tape 100. At both sides of the core thread 155, the outer region of the front stop 300 outwardly of tape is provided with a step 351 and the inner region of the front stop 300 inwardly of tape is provided with a descent slant surface 352. The step 351 extends along the side edge 150 of the fastener tape 100, and has a left-right width W351 that varies as the step 351 extends. The descent slant surface 352 slants downward toward the fastener tape 100 to reach the second side surfaces 340. A curved surface 353 may be provided between the descent slant surface 352 and the step 351.

[0045] It should be noted that the inner region of the front stop 300 provided inwardly of tape and the outer region of the front stop 300 provided outwardly of tape are determined relatively. For example, in the illustrated exemplary case, the inner region of the front stop 300 inwardly of tape is a region provided inwardly of tape from the center of the front stop 300 in the left and right direction. The outer region of the front stop 300 outwardly of tape is a region provided outwardly of tape from the center of the front stop 300 in the left and right direction. The inner and outer regions inwardly and outwardly of tape can be redefined relative to a point shifted leftward or rightward from the center of the front stop 300 in the left-right direction.

[0046] The step 351 of each front stop 300 is provided for avoiding or suppressing an interference with the structure of the slider 500. The descent slant surface 352 of each front stop 300 is provided for avoiding or suppressing an interference with the structure of the slider 500.

[0047] As shown in Fig. 12, separation walls 570 for defining the left and right element passages may be provided at the top wing 510 and the bottom wing 520 respectively. Furthermore, pusher portions 580 for pushing the return portion 234 may be provided on the inner wall of the coupling portion between the top wing 510 and the flange portion 540.

[0048] The outer region of the front stop 300 outwardly of tape may be thinned by the above-described step 351, thereby suppressing an interference between the up or down separation wall 570 and the front stop 300. The front stop 300 is provided with a thinned portion 354 that is not provided on the fastener tape 100.

[0049] In the illustrated example, the thinned portion 354 is positioned outwardly of tape from the side edge 150 of the fastener tape 100. The thinned portion 354 may be thinner than the maximum width H300 of the front stop 300 by the depth D351 of the step 351. The left-right width W351 of the step 351 may vary in the front-rear direction. In the illustrated example, the left-right width W351 of the step 351 at the rear region of the front stop 300 is greater than the left-right width W351 of the step 351 at the front region of the front stop 300. In this case, the coupling strength of the front stop 300 to the core thread 155 at the front region of the front stop 300 may be suitably maintained. At the same time, the interference between the separation wall 570 and the front stop 300 at the rear region of the front stop 300 which enters further into the slider 500 may be effectively suppressed. The interference between the pusher portions 580 and the front stop 300 may be suppressed by the above-described descent slant surface 352.

[0050] In the present embodiment, rotational force may be given to each front stop 300 due to the engagement and contact between the projected engaging portion 380 and the recessed engaging portion 390. When an interference between the front stop 300 and the separation wall 570 or between the front stop 300 and the pusher portions 580 is caused, the rotation of this front stop 300 may possibly be hindered. In the present embodiment, the above-described step 351 and descent slant surface 352 are provided at the front stop 300 so that above problems may be avoided or suppressed to be caused actually.

[0051] In the illustrated example, D351<(H300/3) is satisfied, where D351 indicates the depth of the step 351, and H300 indicates the maximum thickness of the front stop 300. In other words, the depth of the step 351 is less than 1/3 of the maximum thickness of the front stop 300.

[0052] In the illustrated example, D351<(H300/4) is satisfied, where D351 indicates the depth of the step 351, and H300 indicates the maximum thickness of the front stop 300. In other words, the depth of the step 351 is less than 1/4 of the maximum thickness of the front stop 300.

[0053] In the illustrated example, D351<(H300/5) is satisfied, where D351 indicates the depth of the step 351, and H300 indicates the maximum thickness of the front stop 300. In other words, the depth of the step 351 is less than 1/5 of the maximum thickness of the front stop 300.

[0054] In the illustrated example, D351<(H300/6) is satisfied, where D351 indicates the depth of the step 351, and H300 indicates the maximum thickness of the front stop 300. In other words, the depth of the step 351 is less than 1/6 of the maximum thickness of the front stop 300.

[0055] As shown in Fig. 5 and Fig. 8, the step 351 is provided across the front region and the rear region in the outer region of the front stop 300 outwardly of tape. Likewise, the descent slant surface 352 is provided across the front region and the rear region in the inner region of the front stop 300 inwardly of tape. The curved surface 353 is provided to be wider in the left and right direction from the rear side toward the front side. It is envisaged that this may serve to avoid or suppress the interferences with the separation walls 570 and the pusher portions 580 of the slider 500. Technical effects achieved by these structures would be immediately recognized by referring to Figs. 12 and 13.

[0056] Descriptions will be made with references to Figs. 9-11 about processes in which the slider 500 is moved frontward, the left-right pair of fastener stringers 400 are closed, the left-right pair of fastener elements 200 are coupled, and the left-right pair of front stops 300 are housed in the slider 500. Here, in the left-right pair of fastener stringers 400, the left-side front stop 300 of the left-side fastener stringer 400 extends along the side edge 150 of the fastener tape 100 longer than the right-side front stop 300 of the right-side fastener stringer 400. Furthermore, the recessed engaging portion 390 is provided at the rear region of the first side surface 330 of the left-side front stop 300, and the projected engaging portion 380 is provided at the rear region of the first side surface 330 of the right-side front stop 300.

[0057] While the slider 500 is moved frontward from the position illustrated in Fig. 9 to the position illustrated in Fig. 10, engaging portions 210 of each left or right fastener element 200 slide on the side surface of the guide column 530 of the slider 500, and the bases 220 slide on the inner side surface of the flange portion 540 of the slider 500. As would be understandable from Fig. 9, earlier than the right-side front stop 300, the left-side front stop 300 enters into the mouth between the guide column 530 and the flange portion 540 of the slider 500. It should be noted that, the slider 500 has a left-side mouth between the guide column 530 and the left-side flange portion 540 and a right-side mouth between the guide column 530 and the right-side flange portion 540.

[0058] While the slider 500 is moved frontward from the position illustrated in Fig. 10 to the position illustrated in Fig. 11, the projected engaging portion 380 of the right-side front stop 300 which has been entered into the slider 500 through the right-side mouth of the slider 500 touches the recessed engaging portion 390 of the left-side front stop 300 after crossing the center line CL of the slider 500 in the left-right direction, thereby causing the clockwise rotation of the left-side front stop 300 and anticlockwise rotation of the right-side front stop 300. At this moment, the projection 373 of the left-side front stop 300 that has entered into the slider 500 through the left-side mouth is positioned rearward relative to the rear surface 320 of the right-side front stop 300 after crossing the center line CL of the slider 500 in the left-right direction. Each left or right front stop 300 is provided with the slant surface 345 as described above, allowing each front stop 300 to rotate by an appropriate amount. The space SP5 between the slant surface 345 of each front stop 300 and the inner wall surface of the flange portion 540 of the slider 500 may be reduced by the rotation of each front stop 300 and thus the interspace W110 illustrated in Fig. 2 may be reduced.

[0059] In one embodiment, the timing when the slant surface 345 of each front stop 300 hits the inner wall surface of the flange portion 540 of the slider 500 may be earlier than the timing when the bulge 372 of each front stop 300 hits the guide column 530. In other embodiments, the timing when the slant surface 345 of each front stop 300 hits the inner wall surface of the flange portion 540 of the slider 500 may be later than the timing when the bulge 372 of each front stop 300 hits the guide column 530. In yet other embodiments, the timing when the slant surface 345 of each front stop 300 hits the inner wall surface of the flange portion 540 of the slider 500 may be substantially the same as the timing when the bulge 372 of each front stop 300 hits the guide column 530.

[0060] As would be understood by referring to Fig. 11, in the illustrated example, when each front stop 300 is housed in the slider 500, the front surface 310 of each front stop 300 substantially or perfectly matches the contour of the bottom wing 520 of the slider 500. In other embodiments, it is envisaged that, when each front stop 300 is housed in the slider 500, the front surface 310 of each front stop 300 may be positioned frontward from the contour of the bottom wing 520 of the slider 500 by an arbitrary amount.

[0061] As would be understood by referring to Fig. 11, when each front stop 300 is housed in the slider 500, the second side surface 340 and the slant surface 345 of each front stop 300 faces the inner wall surface of the flange portion 540 of the slider 500. When each front stop 300 is housed in the slider 500, the front region of the first side surface 330 of each front stop 300 faces the guide column 530 of the slider 500, and the rear region of the first side surface 330 is positioned rearward from the guide column 530.
