As shown in FIGS. 2 to 8, the upper slider 40 is a slider with an automatic stop function, and includes a main body 50, a pull tab 75, a stopper claw 70, and a pull tab holding cover 80.

The main body 50 includes an upper wing plate 51 and a lower wing plate 52 which are separated from the up-and-down direction and arranged in parallel. The guide post 53 is connected to the upper wing plate 51 and the lower wing plate 52 at the front end portion and the central portion in the width direction; the upper flange 54L and 54R are protruded downward along the left and right side edges of the upper blade 51, and the lower flanges 55L and 55R are protruded upward along the left and right side edges of the lower blade 52. Thereby, the left and right introduction ports 56 separated by the guide post 53 are formed in the front portion of the main body 50, and the engagement opening 57 is formed in the rear portion of the main body 50. Further, a substantially Y-shaped sprocket guiding path 58 that connects the left and right introduction ports 56 and the engaging opening 57 is formed between the upper blade 51 and the lower blade 52, and the sprocket guiding path 58 is provided for a pair of left and right zipper chains. The tooth row 30 is inserted.

Further, as shown in FIG. 3, a chain insertion passage 59 is formed between the upper and lower sides of the main body 50 and the lower flanges 54L, 55L and 54R, 55R, respectively. As will be described in detail below, the gap between the left side chain insertion passages 59 is set to be larger than the gap between the right side chain insertion passages 59 so that the left side chain belt 11L can be separated from the slider 40.

As shown in FIG. 3 and FIG. 4, the front mounting post 60F and the rear mounting post 60R for mounting the tab holding cover 80 are erected side by side in the front-rear direction and are disposed on the upper surface of the upper flap 51. The direction center line CL is on the right side (the side of the fixed side chain belt 11R). Moreover, the front mounting post 60F and the rear mounting The link portion 76 and the stopper claw body 70 of the pull tab 75 are accommodated between the posts 60R, and the claw portions (not shown) provided by the pull tab holding cover 80 and provided at the front and rear ends are engaged with the front and rear mounting posts 60F. The 60R is fixed to the front mounting post 60F and the rear mounting post 60R. Further, as shown in FIG. 3, the upper blade 51 is inserted from the upper surface of the upper blade 51 to the element guide path 58 to form a claw insertion hole for inserting the stopper claw 71 of the stopper claw 70. 51b. Furthermore, in the present embodiment, the front mounting post 60F, the rear mounting post 60R, the stopper claw 70, and the tab holding cover 80 constitute a tab attachment portion.

In this manner, the front mounting post 60F and the rear mounting post 60R are formed on the right side of the center line CL in the width direction of the guide post 53 of the upper flap 51, so that the rigidity of the flaps 51 on the left side is slightly lower than that of the guide post 53. The upper upper wing 51 is easily deflected. Further, together with the front mounting post 60F and the rear mounting post 60R, the blocking claw body 70 is also disposed on the right side of the center line CL in the width direction of the guide post 53 of the upper flap 51, so that as shown in FIG. The stopper claws 71 of the claw body 70 are inserted between the fastener elements 31 on the side of the fixed side chain belt 11R. Therefore, when the fastener element 31 on the side of the separation side chain belt 11L is pulled out from the element guide path 58 through the chain insertion passage 59, the stopper claw 71 does not contact the fastener element 31, so that it can be prevented. The zipper element 31 generates damage caused by the stopper claw 71.

Further, as shown in FIG. 2 to FIG. 5, the upper blade 51 and the lower blade 52 are formed with notches extending from the left front side surface 53a of the guide post 53 toward the outer side in the width direction (the side of the separation side chain 11L). 51a, 52a. The notch portions 51a and 52a are formed so as to extend obliquely outward and rearward in the width direction from the boundary between the left front side surface 53a and the rear side surface 53b of the guide post 53, and then bent in the middle and obliquely extended outward in the width direction and forward. . By this structure Further, the upper side and the lower side flanges 54L, 55L of the left side of the main body 50 are shorter than the upper side of the main body 50 and the lower side flanges 54R, 55R, so that the upper side of the guide post 53 is smaller than the guide rail 53. The rigidity of the lower wing plate 52 and the lower wing plate 52 are slightly lowered, and the left upper wing plate 51 and the lower wing plate 52 are easily deflected.

Further, the opposite side surfaces of the upper side flange 54L and the lower side flange 55L forming the left side chain insertion passage 59 have projections 62a and 62b, respectively, except for the projections 62a and 62b. The straight plate portions 54a and 55a are parallel to each other except for the position in the front-rear direction. Further, as shown in FIG. 3, the gap G1 in the lower direction of the gap between the left side chain insertion passages 59 in the straight plate portions 54a and 55a, and the gap G2 in the lower direction of the gap in the left side chain insertion passage 59 among the projection portions 62a and 62b. It is set to be larger than the upper and lower dimension g of the gap of the right link insertion passage 59, and the upper and lower dimension G2 of the gap of the left link insertion passage 59 among the projections 62a and 62b is set smaller than that of the straight portions 54a and 55a. The gap between the left side chain insertion passages 59 is in the downward direction dimension G1.

Moreover, the projections 62a and 62b have an inclined surface and protrude from the straight plate portions 54a and 55a so as to be smoothly continuous. The upper and lower dimension G2 of the gap of the left chain insertion passage 59 in the projections 62a and 62b and the length of the projections 62a and 62b in the front and rear directions are the fastener elements 31 that do not obstruct the left chain belt 11L from the slider 40. Separate mode setting. Specifically, in the present embodiment, in the state shown in FIG. 9 in which the lateral tension in the width direction is applied to the pair of left and right chain belts 11L and 11R, the straight plate portions 54a and 55a become the second zipper described below. The main body portion corner portion 31d of the sprocket 31b in the front-rear direction rearward direction extends to the engagement opening side in the front-rear direction. Therefore, in the state shown in FIG. 9, the projections 62a and 62b are smaller than the main body corner portion 31d of the second fastener element 31b. The front and rear directions are located on the side of the engaging opening 57. In the present embodiment, the fastener elements 31 located in the upper and lower sliders 40 and 90 are sequentially referred to as first to third fastener elements 31a and 31b from the introduction port 56 side toward the engagement opening 57 side. 31c.

Further, as shown in Fig. 6, the upper side surfaces of the upper side of the main body 50 and the inner side surfaces of the lower side flanges 54L and 55L in the width direction are formed as inclined surfaces 61a and 61b which gradually increase in thickness as they extend outward from the inner side in the width direction. . Therefore, as shown in Fig. 13, the upper corner portions of the fastener element 31 of the separated side fastener tape 11L to which the lateral pulling force is applied abut against the inclined faces 61a, 61b of the upper and lower flanges 54L, 55L, respectively, so that the lateral pulling force is applied. It is efficiently transmitted to the upper blade 51 and the lower blade 52 via the inclined surfaces 61a and 61b. Thereby, as shown in FIG. 14, the chain insertion path 59 between the upper side and the lower side flanges 54L and 55L can be easily expanded.

Further, in the present embodiment, the rear end of the upper left side and the lower side flanges 54L, 55L are located forward of the rear end of the engaging opening 57 side of the slider 40, and are formed behind the upper and lower flanges 54L, 55L. There are notched portions 63a and 63b which are flush with the inner surfaces of the upper blade 51 and the lower blade 52. That is, the notch portions 63a, 63b are respectively formed by the rear end of the upper left and lower flanges 54L, 55L and the inner surfaces of the upper and lower flaps 51, 52, 52L, 55L, 55L, 55L, respectively. And formed. The lengths of the cutout portions 63a and 63b in the front-rear direction are set so that the fastener element 31 does not contact when the separation side chain belt 11L is separated from the upper slider 40. Specifically, first, after the separation side chain belt 11L is separated from the lower side slider 90, the lateral tension of the pair of left and right chain belts 11L and 11R is applied to the outer side in the width direction, and the upper side slider 40 is moved upward. Then, by applying a lateral pulling force, as shown in FIG. 16, the third slider element 31c is in a state where the upper slider 40 is positioned by the upper stopper portion 12. The second fastener element 31b that touches the upper and lower flanges 54L and 55L is rotated as a fulcrum, and is stretched to the left side. At this time, the lengths of the notch portions 63a and 63b in the front-rear direction are set such that the main body portion of the third fastener element 31c does not contact the upper and lower flanges 54L and 55L.

Further, the gap G3 (see FIG. 3) of the chain insertion passage 59 in the notch portions 63a and 63b is set larger than the thickness H of the fastener element 31 (see FIG. 13). Thereby, when the above-described third fastener element 31c is stretched to the left side while being rotated, smooth rotation can be tolerated.

Further, in the present embodiment, as shown in Figs. 2 to 6, the upper surface of the upper blade 51 and the lower surface of the lower blade 52 are formed on the left side of the guide post 53 so as to follow the inner side from the width direction. The inclined faces 51c and 52c whose outer wall thickness gradually becomes small. In other words, the thickness of the upper blade 51 and the lower blade 52 on the left side in the width direction of the guide post 53 is formed to be thinner than the right side in the width direction. Furthermore, the thin wall may be in the range of the left side of the upper wing 51 and the lower wing 52 across the left side of the guide post 53 in the width direction, or the upper wing 51 and the lower wing 52 may be separated by a guide post. A portion other than the portion on the left side in the width direction of 53 (the portion near the guide post 53).

Further, in the present embodiment, the rear end portion formed before the inclined surface 51c formed on the left side in the width direction of the upper blade 51 and the rear end portion formed on the left side inclined surface 52c of the lower blade 52 in the width direction are respectively formed. There are projections 51d, 52d extending in the width direction of the main body 50. Thereby, the front end portion of the upper blade 51 and the lower blade 52 is formed to have a wall thickness with respect to the intermediate portion. Further, the front and rear projections 52d of the lower blade 52 are formed on the same plane as the lower right surface of the lower blade 52 in the width direction. Further, the protrusions 51d and 52d are respectively formed on the upper wing The front end edges of the plates 51 and the lower flaps 52 are slightly separated from each other.

Further, the lower slider 90 has a mirror-symmetric structure in which the upper slider 40 is reversed left and right with respect to the center line CL in the width direction of the guide post 53. Therefore, the upper side slider and the lower side flanges 54L and 55L or the notch portions 63a and 63b of the lower slider 90 having the projections 62a and 62b and the straight plate portions 54a and 55a are located on the left side similarly to the upper slider 40.

Further, in the reverse opening and closing member 13, when the lower side slider 90 is in contact with the lower end stopper 14a of the cylinder pin 14, and the upper side slider 40 is in contact with the rear end of the lower side slider 90, The stopper claw 71 of the upper slider 40 is disposed at a position that avoids the upper surface of the cylinder pin 14, that is, a position that does not contact the tubular pin 14.

Therefore, in the slide fastener 10 including the reverse opening and closing member 13, the fastener element 31 can be from both the upper and lower side sliders 40, 90, and the side on which the plug 16 is inserted (the side of the separation side chain belt 11L) The chain insertion passage 59 between the upper side and the lower side flanges 54L, 55L is separated.

In the zipper 10 of the above-described configuration, the lateral pulling force toward the outer side in the width direction is applied to the pair of left and right chain belts 11L and 11R on the upper side of the upper side slider 40 from the state shown in FIG. 8 (see FIG. 9). The first fastener element 31a (zipper element 31) in the element guide path 58 of the separation side chain belt 11L which is located closest to the inlet port 56 and which is not engaged, abuts against the upper and lower flanges 54L, 55L, respectively. The inclined surfaces 61a and 61b (see FIG. 13) expand the gap between the upper and lower flanges 54L and 55L (see FIG. 14), and the upper blade 51 and the lower blade 52 are closer to the left side than the guide post 53. Part of the deflection (see Figs. 10 and 11) is pulled out from the slider 40. At this time, after the first fastener element 31a, the second fastener element 31b is also similar to the first fastener element 31a from the upper and lower flanges 54L, The 55L straight plate portions 54a and 55a are pulled out. Further, the third fastener element 31c is also blocked from the upper and lower flanges 54L and 55L without being blocked by the projections 62a and 62b (see FIG. 12). Therefore, the pulling operation of separating the separated side chain belt 11L from the slider 40 is smoothly performed without stopping in the middle.

Further, in the present embodiment, after the separation side chain belt 11L is separated from the lower side slider 90, the lateral tension of the pair of left and right chain belts 11L and 11R on the lower side of the upper side slider 40 is continuously applied to the outer side in the width direction. The upper side slider 40 is moved to the upper side. Further, as shown in FIG. 16, by applying the lateral pulling force in a state where the upper slider 40 is positioned by the upper stopper portion 12, the third fastener element 31c touches the upper and lower flanges 54L, The second zipper element 31b of 55L is a fulcrum rotation, and one side is stretched toward the left side. At this time, the corner portion of the main body portion of the third fastener element 31c is located in the cutout portions 63a and 63b, and is not in contact with the upper and lower flanges 54L and 55L, so that the main body portion of the third fastener element 31c is not damaged. Corner.

Thereafter, the second fastener element 31b abuts against the inclined surfaces 61a and 61b of the upper and lower flanges 54L and 55L, respectively, and expands the gap between the upper and lower flanges 54L and 55L to make the upper blade 51 and the lower side. The portion of the flap 52 that is closer to the left side than the guide post 53 is deflected from the upper slider 40 (see FIGS. 17 to 19). Further, the first fastener element 31a is also pulled out from the upper slider 40 at substantially the same time as the second fastener element 31b is pulled out from the upper slider 40.

Further, in the present embodiment, the protrusion portion 51d is formed on the left side in the width direction of the upper blade 51. Therefore, as shown in Fig. 20, even if the left side portion of the thin-wall upper blade 51 is formed, it is fitted to the other slider 40. a chain insertion passage 59 on the right side in the width direction, and a projection portion 51d of the upper blade 51 also abuts against the other slider 40 Upper side flange 54R. Further, since the protruding portion 52d is formed on the left side in the width direction of the lower blade 52, as shown in Fig. 21, even if the left side portion of the thin-walled lower blade 52 is formed to be inserted into the upper and lower inverted state, the other slider 40 is The chain insertion passage 59 on the right side in the width direction and the projection 52d of the lower blade 52 also abut against the upper side flange 54R of the other slider 40. Therefore, the left side portion of the upper blade 51 and the lower blade 52 can be prevented from being fitted into the chain insertion passage 59 on the right side in the width direction of the other slider 40.

Further, the chain insertion passage 59 on the left side in the width direction of the slider 40 is set to be larger than the thickness of the right side portion of the upper blade 51 and the lower blade 52, and thus is formed as a thin upper wing 51 and a lower blade 52. The left side portion is not inserted into the chain insertion passage 59 on the left side in the width direction of the other slider 40, but is passed through the chain insertion passage 59. Therefore, the left side portions of the upper blade 51 and the lower blade 52 are not fitted into the chain insertion passage 59 on the left side in the width direction of the other slider 40. Further, the chain insertion passage 59 on the right side in the width direction of the slider 40 is set to be smaller than the thickness of the right side portion of the upper blade 51 and the lower blade 52, and thus is not formed as the thin upper wing 51 and the lower blade 52. The right side portion is not inserted into the chain insertion passage 59 on the right side in the width direction of the other slider 40.

As described above, according to the slide fastener 10 of the present embodiment, the upper blade 51 and the lower blade 52 are formed to have a thin thickness on the left side in the width direction of the guide post 53 so as to be thinner in the width direction and on the upper blade. The front end portion of the upper left side surface in the width direction of the width direction of the 51 and the lower end surface of the lower left side surface of the lower wing panel 52 are formed with protrusion portions 51d and 52d, respectively, so that the protrusion portions 51d and 52d can be avoided. The flap 51 and the lower flap 52 are fitted into the chain insertion passage 59 of the other slider 40, so that the coating failure of the slider 40 can be prevented.

Further, according to the slide fastener 10 of the present embodiment, the front and rear projections 52d of the lower blade 52 and the lower right surface of the lower blade 52 in the width direction are formed on the same plane, so that the slider 40 can be prevented from being carried in each manufacturing step. Shake when placed on the platform.

Further, as a first modification of the embodiment, as shown in FIG. 22, the rear end edge formed on the left side inclined surface 51c of the upper blade 51 in the width direction and the width of the lower wing 52 may be formed. Instead of the above-described protrusions 51d and 52d, protrusions 51e and 52e extending in the width direction of the main body 50 are formed in front of the front end edge of the inclined surface 52c on the left side. The projections 51e and 52e are formed along the front end edges of the upper blade 51 and the lower blade 52, respectively.

Further, as a second modification of the embodiment, as shown in FIG. 23, notch portions 51a and 52a may be formed in the upper blade 51 and the lower blade 52. In this case, the front side and the lower side flanges 54L and 55L of the main body 50 are substantially the same as the upper side of the main body 50 and the lower side flanges 54R and 55R. Further, in the present modification, the front side protrusion portion 51d of the upper blade 51 is formed in a substantially triangular shape in plan view, and the rear side protrusion portion 51d of the upper blade 51 is formed in a substantially zigzag shape in plan view. Furthermore, the shape of the protrusion 51d may be other figures or characters.

Further, as a third modification of the embodiment, as shown in FIG. 24, the notch portions 51a and 52a of the upper blade 51 and the lower blade 52 may be extended rearward from the rear end portion of the guide post 53, and the main body may be extended. The front end portions of the upper left side and the lower side flanges 54L, 55L of the left side 50 are located rearward of the rear end portion of the guide post 53. Moreover, the notch portions 51a and 52a of the present modification are from the front side of the left side of the guide post 53. The front end of 53a is inclined to the outer side in the width direction and rearward to form a straight line. Moreover, the protrusions 51d and 52d on the front side of the present modification are formed linearly in the width direction outer side and rearward along the notch portions 51a and 52a.

In addition, the present invention is not limited to the above-described embodiments, and can be appropriately modified without departing from the spirit and scope of the invention.
