1 and 2, the slide fastener 700 includes a pair of left and right fastener stringers 400 and a slider 500 for opening and closing the pair of left and right fastener stringers 400. Each fastener stringer 400 includes a fastener tape 100, a fastener element 200 provided along the side edge 150 of the fastener tape 100, a resin front stopper 300 provided on the side edge 150 of the fastener tape 100, and a fastener A back end 600 made of resin or metal is provided on the side edge 150 of the tape 100. The back stop 600 is common to the left and right fastener stringers 400, whereby the left and right fastener stringers 400 are connected on the rear end side.

11 and 12, the slider 500 includes an upper blade plate 510, a lower blade plate 520, a guide post 530, a flange portion 540, a pull attachment column 550, and a pull handle 560. The upper wing plate 510 and the lower wing plate 520 are connected via the guide column 530, and the upper wing plate 510 and the lower wing plate 520 are arranged in parallel to each other. The top view shape of the upper wing plate 510 and the bottom view shape of the lower wing plate 520 are the same. The upper blade plate 510, the lower blade plate 520, the guide post 530, and the flange portion 540 define a Y-shaped element passage for the fastener element 200. The flange portion 540 includes an upper flange portion that extends downward from the left and right side edges of the upper blade plate 510 and a lower flange portion that extends upward from the left and right side edges of the lower blade plate 520. In some embodiments, one of the upper flange portion and the lower flange portion is omitted. The pulling attachment column 550 is provided in a cantilevered manner on the upper surface of the upper wing plate 510. The pull handle 560 has an opening inserted through the pull handle attachment column 550.

Each fastener tape 100 includes a first region 110 in which the fastener element 200 is not provided on the side edge 150, a second region 120 in which the fastener element 200 is provided on the side edge 150, and a front stop 300 on the side edge. 150 has a third region 130 provided at 150. A 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 element 200 is not provided on the side edge 150 and the second region 120 where the fastener element 200 is provided on the side edge 150.

The first region 110 of each fastener tape 100 is expected to be useful when the slide fastener 700 is firmly sewn to another article. FIG. 2 shows a state in which the left and right fastener stringers 400 are connected in a Y-shape, and shows that there is a space W110 between the left and right first regions 110. It is expected that the interval W110 between the left and right first regions 110 is reduced by employing the front stop 300 according to the present embodiment. In addition, the front-rear length of the first region 110 of each fastener tape 100 does not necessarily need to match. The front-rear length of the second region 120 of each fastener tape 100 varies between the embodiments.

Each fastener tape 100 is a woven fabric formed by woven yarn or a knitted fabric formed by knitting yarn. Each fastener tape 100 is a flexible member having a pair of tape surfaces as an upper surface and a lower surface. Each fastener tape 100 includes a tape main portion 140 and a side edge portion 150 on a side edge of the tape main portion 140. The side edge 150 of each fastener tape 100 faces the side edge 150 of the other left and right fastener tape 100, and is therefore sometimes referred to as the opposite side edge. In some embodiments, the side edge 150 includes a portion that is thicker than the tape main portion 140, and in some embodiments, the side edge 150 includes a core string 155, but this is not necessarily the case.

The direction toward the inside of the fastener tape 100 may be referred to as the fastener tape inner side, or the tape inner side for short. A direction toward the outside of the fastener tape 100 may be referred to as a fastener tape outward, abbreviated as tape outward. As an easy-to-understand example, the inside of the tape is a direction from the position outside the tape surface of the fastener tape 100 to the side of the fastener tape toward the tape surface of the fastener tape 100. The tape outward direction is a direction from a position on the tape surface of the fastener tape 100 toward a position outside the tape surface of the fastener tape 100 through the side edge of the fastener tape. In the tape surface of the fastener tape, the directions of the terms “tape inward” and “tape outward” will be similarly understood.

Fastener element 200 is provided on side edge 150 of fastener tape 100. Although a coil element is illustrated as the fastener element 200, it should not be limited to this. In some embodiments, a resin element or a metal element is employed as the fastener element. It is understood that the benefits of the embodiments disclosed herein are enjoyed without depending on the type of fastener element.

The fastener element 200 has an engaging part 210 and a base part 220. The engaging portion 210 is a portion that can engage with the mating fastener element 200. The base 220 is a portion that is located on the inner side of the tape with respect to the engaging portion 210 of the fastener element 200, and for securing the attachment of the fastener element 200 to the fastener tape 100. As understood by those skilled in the art, the engaging portion 210 can contact the guide column 530 of the slider 500, and the base portion 220 can contact the flange portion 540 of the slider 500.

The fastener element 200 according to the illustrated example is a coil element and is configured by winding a monofilament in a spiral shape. The fastener element 200 is configured such that basic units are continuous in the front-rear direction. Each basic unit includes an engaging head 231 configured to be wide in the front-rear direction, an upper leg 232 connected to the upper end of the engaging head 231, a lower leg 233 connected to the lower end of the engaging head 231, And an inversion part 234 connected to the other end of the lower leg part 233 and connected to the other end of the upper leg part of the adjacent basic unit. The engaging head 231 does not exist on the side edge 150 of the fastener tape 100. The upper leg 232 and the lower leg 233 cross the core string 155 of the side edge 150 of the fastener tape 100 and extend inward of the tape.

The width W200 of the fastener element 200 is determined by the first virtual plane PL1 and the second virtual plane PL2 that are parallel to each other. As shown in FIGS. 3 and 6, the first virtual plane PL <b> 1 is provided with a point or a plane of each engaging portion 210 that is located most outward from the tape. On the second virtual plane PL2, the points or planes of the respective bases 220 located most inside the tape are arranged in the same plane.

In other words, the point or surface of each engaging portion 210 that is farthest from the side edge portion 150 of the fastener tape 100 is disposed on the first virtual surface PL1. On the second virtual plane PL2, the point or surface of each base 220 farthest from each engaging portion 210 is disposed.

In the coil element according to the illustrated example, the flat surface of each engagement head 231 is arranged on the first virtual plane PL1. A point of each reversing portion 234 located at the innermost side of the tape is arranged on the second virtual plane PL2.

When the slide fastener 700 is used as a reference, the first virtual plane PL1 defines the left and right inner boundaries of the fastener element 200. The second virtual plane PL2 defines the left and right outer boundaries of the fastener element 200.

Each front stop 300 has a crescent-shaped top view. Each front stop 300 connects the front surface 310 facing the first region 110, the rear surface 320 facing the second region 120, the front surface 310 and the rear surface 320, the first side surface 330 facing the outside of the tape, the front surface 310 and the rear surface 320, It has the 2nd side 340 which faces the inside of a tape. Each front stop 300 has an upper surface 350 that is spaced apart from the tape upper surface 101 of the fastener tape 100, and has a lower surface 360 that is flush with the tape lower 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 portion exists between the first side surface 330 and the rear surface 320.

Each front stop 300 is integrally formed with respect to the side edge 150 of the fastener tape 100 based on insert molding in a non-limiting form. The front-rear length of the left front stop 300 is larger than the front-rear length of the right front stop 300. The left front stop 300 extends longer along the side edge 150 of the fastener tape 100 than the right front stop 300.

In the rear region of the first side surface 330 of the left front stop 300 shown in FIG. 3, a concave engagement portion 390 that is recessed inward of the fastener tape beyond the first virtual surface PL1 is provided. Concave engagement portion 390 has a side surface 391 that intersects first virtual surface PL1.

6 is provided in the rear region of the first side surface 330 of the right front stop 300 shown in FIG. 6 with a convex engagement portion 380 projecting outward from the fastener tape beyond the first virtual surface PL1. The convex engagement portion 380 has two side surfaces 381 that intersect the first virtual plane PL1.

When the left and right front stops 300 are accommodated in the slider by the advance of the slider 500, the concave engagement portion 390 of the left front stop 300 and the convex engagement portion 380 of the right front stop 300 are engaged and contacted, and the left front stop The stop 300 is given a clockwise rotational force, and the right front stop 300 is given a counterclockwise rotational force. The second side surface 340 of each of the left and right front stops 300 includes an inclined surface 345 extending from the front region to the rear region so as to approach the second virtual surface PL2, and accordingly, each front stop 300 is provided. Each front stop 300 is allowed to rotate until the second side surface 340 contacts the inner wall surface of the flange portion 540 of the slider 500.

Note that the front region and the rear region of the front stop 300 are relative. For example, in the illustrated example, the front region of the front stop 300 is a region that is ahead of the center of the front stop 300 in the front-rear direction. The rear region of the front stop 300 is a region located behind the center of the front stop 300 in the front-rear direction. The front and rear regions can be defined in light of a point slightly shifted in the front-rear direction from the front-rear center of the front stop 300.

The interval W110 shown in FIG. 2 is reduced by the rotation of each of the front stops 300. By reducing the interval W110 shown in FIG. 2, the appearance of the closed slide fastener 700 is improved, the ease of sewing is ensured, or the good startability of the slider 500 is secured. The startability of the slider is equal to the ease of moving the slider in the stopped state.

As shown in FIGS. 3 and 6, each front stop 300 according to the illustrated example has a rounded first protrusion that protrudes inward from the front surface 310 and the second side surface 340 beyond the second virtual surface PL <b> 2. It has an edge 371. The first edge portion 371 is positioned inward of the tape with respect to the second side surface 340, and the second side surface 340 extends closer to the second virtual surface PL2 as it extends rearward. In the left front stop 300 shown in FIG. 3, the inclined surface 345 of the second side surface 340 intersects the second virtual surface PL2 in the process of extending backward. At this time, if a point where the inclined surface 345 and the second virtual surface PL2 intersect is defined as an intersection, the inclined surface 345 is located inward of the tape from the second virtual surface PL2 in front of the intersection and behind the intersection. The inclined surface 345 is located outside the tape with respect to the second virtual surface PL2. In the right front stop 300 shown in FIG. 6, the inclined surface 345 of the second side surface 340 does not intersect the second virtual surface PL2 in the process of extending backward. However, in other embodiments, the inclined surface 345 of the right front stop 300 may intersect the second virtual surface PL2.

3 is coupled to the rear surface 320 via a second edge 376 in which the inclined surface 345 of the second side surface 340 of the left front stop 300 shown in FIG. The inclined surface 345 of the second side surface 340 of the right front stop 300 shown in FIG. 6 is coupled to the rear surface 320 via a rounded second edge 376. The inclined surface 345 of the second side surface 340 of the right front stop 300 and the boundary 377 of the second edge 376 are on the second virtual surface PL2 or in the vicinity of the second virtual surface PL2. The second edge 376 of the right front stop 300 intersects the second virtual plane PL2.

As shown in FIGS. 3 and 6, a rounded raised portion 372 protruding outward from the tape is provided in the front region of the first side surface 330 of each front stop 300. The raised portion 372 is configured to be able to contact the guide column 530 of the slider 500. In the left front stop 300 shown in FIG. 3, the raised portion 372 does not protrude outward from the tape beyond the first virtual surface PL1, and the most outward position of the raised portion 372 is on the first virtual surface PL1. . On the other hand, in the right front stop 300 shown in FIG. 6, the raised portion 372 protrudes outward of the tape beyond the first virtual plane PL1. It is ensured that the interval between the guide column 530 and the flange portion 540 of the slider 500 is sufficiently closed.

In the rear region of the first side surface 330 of each front stop 300, a protruding portion that protrudes outward from the tape beyond the first virtual surface PL1 is provided. In the left front stop 300 shown in FIG. 3, a protruding portion 373 is provided in the rear region of the first side surface 330, and the above-described concave engaging portion 390 is provided adjacent to the front of the protruding portion 373. The protrusion 373 protrudes outward of the tape from the first virtual surface PL1. An inclined surface 375 is provided adjacent to the front of the concave engaging portion 390. A recess 374 is provided adjacent to the front of the inclined surface 375. The above-described raised portion 372 is provided adjacent to the front of the recess 374.

In the right front stop 300 shown in FIG. 6, the convex engagement portion 380 described above is provided in the rear region of the first side surface 330, and the inclined surface 375 is provided adjacent to the front of the convex engagement portion 380. . A recess 374 is provided adjacent to the front of the inclined surface 375. The above-described raised portion 372 is provided adjacent to the front of the recess 374.

The raised portion 372 closes the opening between the guide column 530 and the flange portion 540 of the slider 500. The raised portion 372 is rounded when viewed from above, and a small contact resistance between the raised portion 372 and the guide column 530 is achieved. The depression 374 reduces the contact area between the first side surface 330 of the front stopper 300 and the guide column 530. The inclined surface 375 promotes stable displacement of the front stop 300 between the guide column 530 and the flange portion 540.

The inclined surface 375 of the first side surface 330 is called a first inclined surface, the inclined surface 345 of the second side surface 340 is called a second inclined surface, or the inclined surface 375 of the first side surface 330 is called a second inclined surface, The inclined surface 345 of the second side surface 340 may be referred to as a first inclined surface. In some embodiments, the first inclined surface and the second inclined surface are parallel to each other.

As shown in FIGS. 4 and 7, each front stop 300 has an upper surface 350 spaced from the tape upper surface 101 of the fastener tape 100 and a lower surface 360 that is flush with the tape lower surface 102 of the fastener tape 100. A stepped portion 351 is provided in the tape outer region of the front stopper 300 with the core string 155 interposed therebetween, and a downward inclined surface 352 is provided in the tape inner region. The step portion 351 extends along the side edge 150 of the fastener tape 100 and has a left-right width W351 that changes in the extending process. The downward inclined surface 352 is inclined downward toward the fastener tape 100 until it is connected to the second side surface 340. A curved surface 353 is provided between the downward inclined surface 352 and the stepped portion 351.

Note that the tape inner area and the tape outer area of the front stop 300 are relative. For example, in the illustrated example, the tape inner area of the front stop 300 is an area located inside the tape with respect to the center of the front stop 300 in the left-right direction. The tape outer region of the front stop 300 is a region located on the tape outer side than the center of the front stop 300 in the left-right direction. The tape inner area and the tape outer area can be defined in light of a point slightly shifted in the left-right direction from the center of the front stop 300 in the left-right direction.

The step portion 351 of each front stop 300 is provided in order to avoid or suppress interference with the structure of the slider 500. The downward inclined surface 352 of each front stop 300 is provided in order to avoid or suppress interference with the structure of the slider 500.

The front stop 300 is provided with a thin portion 354 that is not provided on the fastener tape 100.

In the example of illustration, the thin part 354 is located in the tape outer side rather than the side edge part 150 of the fastener tape of the front stop 300. FIG. The thin portion 354 is thinner than the front stop 300 having the maximum thickness H300 by the depth D351 of the step portion 351. The left-right width W351 of the stepped portion 351 changes in the front-rear direction. In the illustrated example, the left and right width W351 of the step portion 351 in the rear region of the front stop 300 is larger than the left and right width W351 of the step portion 351 in the front region of the front stop 300. In this case, the bonding strength of the front stopper 300 with respect to the core string 155 is suitably maintained in the front region of the front stopper 300, and the partition wall 570 and the front stopper 300 are further rearward in the region of the front stopper 300 that enters the slider 500 more. Interference can be effectively suppressed. The above-described downward inclined surface 352 suppresses interference between the pressing portion 580 and the front stop 300.

In the present embodiment, each front stop 300 is provided with a rotational force due to the engagement and contact between the convex engagement portion 380 and the concave engagement portion 390. If interference between the front stop 300 and the partition wall 570 or interference between the front stop 300 and the pressing portion 580 occurs, the rotation of the front stop 300 may be hindered. In the present embodiment, the above-described stepped portion 351 and the downward inclined surface 352 are provided in the front stop 300 to avoid or suppress the occurrence of such a problem.

In the illustrated example, D351 <H300 / 3 is satisfied, where D351 is the depth of the stepped portion 351 and H300 is the maximum thickness of the front stop 300. In other words, the depth of the stepped portion 351 is smaller than one third of the maximum thickness of the front stop 300.

In the illustrated example, D351 <H300 / 4 is satisfied, where D351 is the depth of the stepped portion 351 and H300 is the maximum thickness of the front stop 300. In other words, the depth of the stepped portion 351 is smaller than a quarter of the maximum thickness of the front stop 300.

In the illustrated example, D351 <H300 / 5 is satisfied, where D351 is the depth of the stepped portion 351 and H300 is the maximum thickness of the front stop 300. In other words, the depth of the stepped portion 351 is smaller than one fifth of the maximum thickness of the front stop 300.

In the illustrated example, D351> H300 / 6 is satisfied, where D351 is the depth of the stepped portion 351 and H300 is the maximum thickness of the front stop 300. In other words, the depth of the stepped portion 351 is larger than 1/6 of the maximum thickness of the front stop 300.

As shown in FIGS. 5 and 8, the stepped portion 351 is provided across the front and rear regions of the tape outer region of the front stop 300. Similarly, the downward inclined surface 352 is provided across the front and rear regions of the tape inner region of the front stop 300. The curved surface 353 is provided so that the lateral width is widened from the rear to the front. It is expected that avoidance or suppression of interference between the partition wall 570 and the pressing portion 580 of the slider 500 is sufficiently promoted. The effect achieved by these structures will be readily understood from the reference to FIGS.

As can be understood from FIG. 9, the left front stop 300 enters the opening between the guide column 530 and the flange portion 540 of the slider 500 before the right front stop 300. The slider 500 has a left opening between the guide column 530 and the left flange portion 540, and a right opening between the guide column 530 and the right flange portion 540.

In the process of moving the slider 500 forward from the slider position shown in FIG. 10 to the slider position shown in FIG. 11, the convex engagement portion 380 of the right front stop 300 that has entered the slider 500 from the right opening of the slider 500 Crosses the center line CL in the direction and contacts the concave engaging portion 390 of the left front stop 300, thereby causing the left front stop 300 to rotate clockwise and the right front stop 300 to rotate counterclockwise. . At this time, the protrusion 373 of the left front stop 300 that has entered the slider 500 from the left opening is positioned behind the rear surface 320 of the right front stop 300 beyond the center line CL in the left-right direction of the slider 500. The left and right front stops 300 are provided with the inclined surfaces 345 as described above, and an appropriate amount of rotation of each front stop 300 is allowed. The interval SP5 between the inclined surface 345 of each front stop 300 and the inner wall surface of the flange portion 540 of the slider 500 is reduced by the rotation of each front stop 300, and the interval W110 shown in FIG. 2 is reduced.

In one embodiment, the timing at which the inclined surface 345 of each front stop 300 collides with the inner wall surface of the flange portion 540 of the slider 500 is earlier than the timing at which the raised portion 372 of each front stop 300 collides with the guide column 530. In another embodiment, the timing at which the inclined surface 345 of each front stop 300 collides with the inner wall surface of the flange portion 540 of the slider 500 is later than the timing at which the raised portion 372 of each front stop 300 collides with the guide column 530. . In still another embodiment, the timing at which the inclined surface 345 of each front stop 300 collides with the inner wall surface of the flange portion 540 of the slider 500 is substantially the same as the timing at which the raised portion 372 of each front stop 300 collides with the guide column 530. Are the same timing.

As can be understood from the reference to FIG. 11, in the illustrated example, when each front stop 300 is accommodated in the slider 500, the front surface 310 of each front stop 300 substantially corresponds to the contour of the lower blade 520 of the slider 500. Or match perfectly. In other embodiments, when each front stop 300 is housed in the slider 500, the front surface 310 of each front stop 300 may be positioned forward to any extent relative to the contour of the lower blade 520 of the slider 500. Expected.

As understood from the reference of FIG. 11, when each front stop 300 is accommodated in the slider 500, the second side surface 340 and the inclined surface 345 of each front stop 300 are on the inner wall surface of the flange portion 540 of the slider 500. opposite. When each front stop 300 is accommodated 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 more than the guide column 530.
