(third embodiment) Next, the top stop 1A of the third embodiment and the garment 101 including the same will be described. In addition, about the structure similar to 1st Embodiment, the code|symbol is attached|subjected in drawing, and the description is abbreviate|omitted.

Fig. 18 is a plan view showing a garment 101 as a zippered product including the top stop 1A according to a third embodiment of the present invention, viewed from the front side. Fig. 19 is the line of sight of arrows in the section XIX-XIX of Fig. 18 . FIG. 20 is a plan view of one of the element rows 50 and the top stop 1A viewed from the front side.

Clothes 101 as a zippered product of the present embodiment include: a pair of fastener element members 52, a plurality of fastener elements 51 are respectively mounted on a core wire 43 to form left and right fastener element rows 50; The chain element row 50 engages; the upper stopper 1A and the upper stopper 2A are installed on the core wire 43 to limit the further upward movement of the slider 60; Zipper attachment member for top stop 1A, top stop 2A.

In the garment 101 as such a zippered product, when the user moves the slider 60 upward, the left and right element rows 50 are closed, and when the user moves the slider 60 downward, the left and right element rows 50 are opened. And, the slider 60 is pulled down to the lower end position, the plunger, not shown, is drawn out from the seat bar, and the plunger is pulled upward through the element guide path 64 of the slider 60, whereby the left The element member 52 is separated from the right element member 52 . In this state, the slider 60 remains on the right element member 52 .

Also, in the present embodiment, the slider 60 remaining on the right element member 52 can be detached from the right element member 52 via the top stop 1A in the manner described below. Furthermore, a new or repaired slider 60 can be attached to the right element member 52 via the top stop 1A.

FIG. 21 is a perspective view showing the top stop 1A. FIG. 22( a ) is a plan view of the top stop 1A viewed from the front side, and FIG. 22( b ) is a bottom view of the top stop 1A viewed from the back side. Fig. 23(a) is a side view of the top stop 1A viewed from the XXIII direction of Fig. 22(a), and Fig. 23(b) is a side view of the top stop 1A viewed from the XXIII' direction of Fig. 22(a) side view. FIG. 24 is a front view of the top stop 1A viewed from the XXIV direction of FIG. 22( a ).

As shown in FIGS. 21 to 24 , the top stop 1A is formed so as to wrap around the core wire 43 . The top stop 1A includes a top stop fixing portion 13 fixed to the core wire 43 , a top stop engaging portion 14 provided on the other (left) element row 50 side of the top stop fixing portion 13 in the left-right direction, And the top stop wing part 15 extends from the top stop fixing part 13 toward the side opposite to the top stop engaging part 14 in the left-right direction.

The top stop fixing part 13 of the top stop 1A includes: a first base part 110 and a second base part 112, which are separated from each other in the vertical direction of the top stop 1A with respect to the core wire 43 and provided on the front side; and elastically deformable claws. The portion 120 extends from the first base portion 110 , and extends obliquely from one side to the other side in the left-right direction as it moves toward the second base portion 112 . In addition, a slider passage 130 through which the flange 65 (see FIG. 27 ) of the slider 60 can pass is formed in a gap between the claw portion 120 and the wall surface 120 a facing each other of the second base portion 112 , and the wall surface 112 a. Therefore, the slider 60 can be attached to and detached from the element member 52 through the slider passage 130 .

Furthermore, the top stop fixing part 13 includes an extension part 123 extending along the vertical direction between the first base part 110 and the second base part 112 . The extension part 123 is designed to be lower than the first base part 110 and the second base part 112 in the front-back direction. That is, the surface (first surface) 123 a of the extension portion 123 is formed on the back side of the surface (second surface) 110 c of the first base 110 and the surface 112 c of the second base 112 . Moreover, the extension part 123 of this embodiment connects the first base part 110 and the second base part 120 at the outlet side of the slider passage 130 , but the extension part 123 does not necessarily connect the first base part 110 and the second base part 120 .

The surface 110c of the first base portion 110 includes stopper portions 19 further protruding toward the front and back directions respectively. The stopper part 19 is a part where the shoulder 64b of the upwardly moving slider 60 abuts against and substantially restricts further upward movement of the slider 60 in a normal state where the left and right element rows 50 are not separated. Therefore, the first base 110 cannot pass through the element guide path 64 of the slider 60 .

On the other hand, the height of the front-back direction of the 2nd base part 112 is formed so that the element guide path 64 may pass. That is, the thickness of the second base portion 112 in the front-back direction is set to be slightly smaller than the distance between the upper blade 61 and the lower blade 62 of the slider 60, and is set so that it can pass through the rear opening 64a of the element guide path 64. and one of the (right) shoulders 64b between the size.

The slider passage 130 is formed between the base end of the claw 120 and the walls 120 a and 112 a of the second base 112 on one side in the left-right direction when the slider 60 is attached to the right element member 52 . The entrance portion 130 a forms an exit portion 130 b between the front end portion of the claw portion 120 and the wall surfaces 120 a and 112 a of the second base portion 112 on the other side in the left-right direction.

Specifically, the wall surface 112a of the second base portion 112 includes an inclined surface 112a1 inclined relative to the up-down direction. The stepped surface 112a2 and the widthwise wall surface 112a3 extending in the left-right direction on the entrance portion 130a side with respect to the inclined surface 112a1. Furthermore, in this embodiment, the step surface 112a2 also extends along the left-right direction.

Therefore, the interval in the inlet portion 130a of the slider passage 130 is wider than the interval in the outlet portion 130b. In addition, the distance between the slider passage 130 including the inclined surface 112a1 of the second base 112 and the wall surface 120a of the claw 120 is gradually narrowed from the entrance 130a side toward the exit 130b side. Furthermore, the distance between the outlet portion 130b side of the slider passage 130 including the inclined surface 112a1 of the second base portion 112 and the wall surface 120a of the claw portion 120 is designed to be more convex than the slider 60 in the state where the claw portion 120 is not elastically deformed. The width of the rim 65 is narrower.

Thereby, the slider passage 130 can enlarge the space|interval in the entrance part 130a, and can make insertion of the slider 60 easy. And, the slider passage 130 is set to the minimum interval as follows: when using the normal slide fastener 100, the slider 60 is prevented from being inadvertently disengaged from the right element member 52 through the top stop 1A, and the claw can be 120 is elastically deformed to allow the slider 60 to move in and out.

Moreover, when the slider 60 is installed, the claw portion 120 is elastically deformed on the side of the extension portion 123, but since the left wall surface 123c of the extension portion 123 is disposed opposite to the front end portion of the claw portion 120, the elastic deformation of the claw portion 120 is caused. The movable range is limited, so as to prevent the claw portion 120 from being damaged when an excessive force acts on the claw portion 120 .

And since the step surface 112a2 bulges so that the exit part 130b of the slider passage 130 may be blocked, it can prevent more reliably that the slider 60 will pass through the slider passage 130 accidentally and detach the slider 60 from the right element member 52. However, when the slider 60 is attached to the right element member 52 and the claw portion 120 is elastically deformed by the slider 60 to expand the width of the slider passage 130 when the slider 60 is attached to the right element member 52, the step surface 112a2 is separated from the slider to such an extent that it can pass through the slider passage 130. The passage 130 is bulged out.

As shown in FIG. 22( b ), a fixing member pressing portion 136 is formed in a ring shape at a position facing the claw portion 120 in the front-back direction on the back side with respect to the core wire 43 . The fixing member pressing portion 136 penetrates along the front-back direction, and pushes the core wire 43 through its opening.

Furthermore, the top stop engaging portion 14 of the top stop 1A includes a pair of gear engaging portions 170 separated from the top stop fixing portion 13 along the vertical direction at one end portion in the left and right direction with respect to the core wire 43 , gear meshing portion 171 . A pair of gear engaging portions 170 and a gear engaging portion 171 are respectively disposed on the first base portion 110 and the second base portion 112 . A gear insertion recess 172 is provided between the gear meshing portion 170 and the gear meshing portion 171 in the vertical direction. The gear insertion recess 172 is formed in the same manner as the gear insertion gap 59a between the chain elements 51 or the gear insertion gap 59b between the chain element 51 and the top stop 1A, and the gear insertion recess 172 is formed between the adjacent gear insertion gap 59b. The distance between them is designed to be equal to the distance between adjacent gear insertion gaps 59a and 59b.

Furthermore, the top stop wing portion 15 of the top stop 1A extends from the extension portion 123 toward the side opposite to the core wire 43 in the left-right direction. The top stop wing portion 15 includes a through hole 15a penetrating in the front-back direction at the center.

In the present embodiment, at the back side with respect to the core wire 43 , the back surfaces of the top stop fixing portion 13 (the first base portion 110 , the second base portion 112 , and the extension portion 123 ) and the top stop wing portion 15 are formed continuously. single flat surface.

The extension portion 123 of the top stop fixing portion 13 includes a flat first side wall surface 123b that stands upright from the surface 15b in the front and back direction of the top stop wing portion 15 and extends along the vertical direction toward the left and right directions. The direction extends to form a step difference between the surface 123a of the extension portion 123 and the surface 15b of the top stop wing portion 15 . The first side wall surface 123b of the extension portion 123 is formed at the same position as the first side wall surface 58a of the thin portion 58 of the fastener element 51 in the left-right direction in a state attached to the core wire 43 .

FIG. 25 is a schematic diagram schematically illustrating a sewing process for sewing the right element member 52 to the material 102 . As shown in FIG. 25 , the material 102 is placed on the surface 15 b of the top stop wing 15 of the top stop 1A and the surface 55 b of the element wing 55 of the plurality of fastener elements 51 , and the upper stop is aligned with the material 102 . When the piece 1A and the fastener element 51 are sewn, the side surface of the material 102 can be pressed against the first side wall surface 123b of the extension part 123 and the first side wall surface 58a of the thin-walled part 58 of the fastener element 51, and can be opposed to each other. Position the top stop 1A and the chain elements 51 on the material 102 .

Furthermore, when sewing the elements 51 to the material 102, the gear insertion gap 59a between the adjacent elements 51 in the vertical direction, or the gear insertion gap 59b between the elements 51 and the top stop 1A The first conveying gear 86 and the second conveying gear 87 of the sewing machine are inserted, and the fastener elements 51 are supported by the first conveying gears 86 and the second conveying gears 87 while conveying the fastener elements 51, thereby suppressing the left and right swinging of the fastener elements 51 or distortion. Furthermore, by inserting the teeth of the first conveyance gear 86 and the second conveyance gear 87 into the gear insertion recessed portion 172 of the top stop 1A, swinging or twisting of the top stop 1A can also be suppressed.

Furthermore, since the top stop wing 15 includes one through hole 15a penetrating in the front and back direction, it is necessary to sew the fastener element 51 and the top stop 1A together with the through hole 55a of the fastener element wing 55 to the material 102 during the sewing process. In the position of these through-holes 15a, 55a, the sewn part 81 can be pierced in the fabric 102. Thereby, the element wing part 55 and the top stopper wing part 15 can be firmly fixed to the material|dough 102 by the sewing part 81, and the slide fastener 100 can maintain a predetermined|prescribed posture more stably.

The first base portion 110 and the second base portion 112 of the top stop fixing portion 13 respectively include a flat second side wall surface 110b and a second side wall surface 112b. The surface (first surface) 123 a in the rear direction stands upright and extends in the up-down direction toward the left-right direction. The second side wall surface 110b and the second side wall surface 112b of the first base part 110 and the second base part 112 are formed on the second side wall surface of the thick part 57 of the fastener element 51 in the left-right direction in the state attached to the core wire 43 . 57a same position.
