Description

zipper

technical field

The present invention relates to a slide fastener of a top-open type in which the slide fastener can be opened without a slide operation of a slider.

Background technique

Conventionally, there is known a slide fastener in which a slide fastener in which a pair of left and right engaging element rows are in an engaged state can be instantaneously separated without performing a sliding operation of a slider.

For example, a slide fastener with the following parts is disclosed in Japanese Publication No. 55-7135 (Patent Document 1): a pair of left and right zipper stringers, which are formed by disposing engaging element rows along the opposite end edges of the zipper strings; sliders, A pair of left and right engaging element rows are inserted through the engaging element guide passage of the slider, and the slider switches the engaging element row into an engaged state and a separated state by sliding along the engaging element row; The insertion tube and socket installed on one end side of the pair of left and right zipper strings; and the upper opening part, which temporarily stops the slider sliding to close the zipper on the rear end side where the separate insert is installed. Opposite the other end side.

In the slide fastener described in this patent document 1, the engaging element row is extended to the front end side of the top opening of one fastener stringer and installed, and a front terminal end of the engaging element row is installed further forward. A top stop that locks the slide of the slider. Correspondingly, at the front side of the top fastener of the other fastener stringer, the engaging element row and the core of the fastener tape are removed to form a thin slider insertion and detachment edge.

In the slide fastener described in this patent document 1, when using the usual method of use such as opening and closing of the slide fastener along with the slide of the slider, the slider is installed on the upper opening part and the separation insert on the fastener stringer. Swipe between widgets. By this sliding operation, the slide fastener can be brought into an engaged state or a disengaged state.

In addition, in the slide fastener described in Patent Document 1, the slide fastener can be brought into the opened state quickly without performing a slide operation of the slider. When the zipper is quickly separated without sliding the slider, first slide the slider to the front end and exceed the top opening, and make the slider and the top stop installed on one side of the zipper stringer Abut.

In a state where the slider is slid to a position where it abuts against the top stop, the fastener stringer on the side where the engaging element row is attached holds the slider. However, since the slider inserting and detaching edge portion is formed thinner than the thickness of the fastener tape since the row of engaging elements and the core are removed, it can pass through the tape insertion passage formed along the end edge of the flange in the slider. And pull out. Therefore, in the state where the slider is slid to the position where it is in contact with the top stop, if a force is applied to open the front ends of the left and right pair of fastener stringers in the direction of pulling the left and right apart, the slider can be opened. The fitting and disengaging edge is pulled out from the engaging element guide passage of the slider.

When the slider fitting and detachment edge part is pulled out from a slider, the meshing element row of the slide fastener which is meshed can be separated sequentially. When the engagement of the engagement element rows with each other is completely disengaged, the cannula can be pulled out from the receptacle of the separation insert. When the insertion tube is pulled out from the socket of the separation insert, the fastener stringers on the left and right are completely separated from each other, and the case where the fastener stringers are separated from the top stop side in this way is called a top-opening slide fastener.

In this way, according to the zipper described in Patent Document 1, when the zipper is to be separated quickly, after the slider is slid over the upper opening to abut against the top stop, it is necessary to apply a pair of left and right zipper fastener stringers. The force in the direction of pulling the front end sides of each other to the left and right. In addition, this zipper can be applied to the locking of the left and right front sides of the jacket.

In addition, in U.S. Patent No. 2,423,202 specification (Patent Document 2), a slide fastener having the following components is disclosed: a pair of left and right fastener stringers formed by disposing rows of engaging elements along opposite end edges of the fastener tapes; and a slider, A pair of left and right engaging element rows are inserted through the engaging element guide passage of the slider, and the slider switches the engaging element rows into an engaged state and a separated state by sliding along the engaging element rows. In front of the front termination end of the engaging element row on one side of the zipper fastener stringer (indicated as stringer 10 in Patent Document 2), a top stop code for locking the slider at the sliding end on the engaging side is installed. (Represented as stop 16 in Patent Document 2).

Correspondingly, in front of the front termination end of the engaging element row of the other zipper stringer (indicated as stringer 11 in Patent Document 2) constructed in a pull-out manner, a row of removing engaging elements is formed. On the other hand, a thin slider inserting and disengaging edge (referred to as a separator 17 in Patent Document 2) is formed at the front end of the slider engaging and disengaging edge to temporarily stop the slider at a position compared with the engaging and sliding end. The upper opening at the rear (in Patent Document 2, it is a convex part shown as projecting knobs 26').

In the slide fastener described in Patent Document 2, when using the usual method of opening and closing the slide fastener along with the sliding of the slider, the slider is positioned at the top of the fastener stringer compared to the top opening. Slide in the rear range. By this sliding operation, the slide fastener can be brought into an engaged state or a disengaged state.

And when the slide fastener in the engaged state is quickly separated without sliding the slider, the slider is first brought into contact with the upper opening (the state shown in FIG. 1 of Patent Document 2), And pull the slider from the belt insertion passage of the slider to insert and break away from the edge. Then, as shown in FIG. 2 of Patent Document 2, a part of the slider fitting and detaching edge part is in the state exposed from the tape insertion path of the slider.

Next, the operation of sliding the slider toward the tip side is performed, and after the slider is brought into contact with the top stop, the slider fitting and detaching edge is further pulled out from the tape insertion passage of the slider. As shown in FIG. 3 of Patent Document 2, by performing this series of operations, the slider fitting and detaching edge can be pulled out from the engaging element guide passage of the slider. Then, the meshing element rows in the meshed state can be sequentially separated by pulling the left and right fastener stringers apart.

In addition, Japanese Patent Publication No. 28-4275 (Patent Document 3) discloses a slide fastener having the following components: a pair of left and right fastener stringers formed by arranging rows of engaging elements along opposite end edges of the fastener tapes; A pair of left and right engaging element rows are inserted through the engaging element guide passage of the slider, and the slider switches the engaging element row into an engaged state and a disengaged state by sliding along the engaging element row. Further ahead of the front termination end of the engagement element row on the pull-out side of the zipper, a top stop (represented as a sleeve in Patent Document 3) that locks the slider at the end of the engagement slide is installed. tube 52).

In the slide fastener described in Patent Document 3, when using the usual method of opening and closing the slide fastener along with the sliding of the slider, the slider is positioned at the upper opening compared with the top opening attached to the fastener stringer. Slide within the rear range to make the zipper engaged or disengaged.

On the other hand, when the slide fastener in the meshed state is quickly separated without sliding the slider, the slider is brought into contact with the upper opening in advance (the state shown in FIG. 7 of Patent Document 3). ), and the slider is largely rotated in a direction away from the top stop (counterclockwise in the embodiment shown in Patent Document 3). Then, as shown in FIG. 8 of Patent Document 3, the flange of the slider (referred to as flange 56 in FIG. 7 shown in Patent Document 3) can be inserted through the top stop (shown in Patent Document 3). It is described as the sleeve 52 in Fig. 7) and the frontmost engaging element (described as the uppermost engaging member 53 in Fig. 7 shown in Patent Document 3), so that the zipper string can be moved from the slider to the Pull out with threaded passage.

Patent Document 3: Japanese Patent Publication No. 28-4275

In the case of using the slide fasteners described in the above-mentioned Patent Document 1 and Patent Document 2 and performing the opening and closing of the slide fastener with the usual method of use accompanied by the slide of the slider, it is necessary to make the slide fastener reach the engagement sliding end of the slider. within the range (for example, in the embodiment described in Patent Document 1, within the range between the top opening and the separation insert). This is because, if the slider is slid to the engaging and sliding end of the zipper (the state of being in contact with the top stop), the insertion and disengagement edge of the slider will be pulled out from the engaging element guide path of the slider, causing the zipper to be incompatible with the use of the slider. Those who intended to separate.

In addition, on the contrary, when the zipper in the meshing state is to be separated quickly, the slider must first be slid to the meshing sliding end beyond the normal range of use, and then the left and right pair of zipper fastener chain belts must be slid. The operation of pulling the front sides away from each other to the left and right. That is, there is a disadvantage that the slide fastener cannot be separated instantaneously.

In addition, in the slide fastener described in Patent Document 3, when the slider is rotated counterclockwise to pull out one fastener stringer from the slider, the flange of the slider needs to be positioned between the front stop portion and the front end. between the meshing elements. It is not easy to pass the flange of the slider between the front stop and the frontmost engaging element, and it is likely to be an obstacle to the rapid separation of the zipper.

The feature of the slide fastener is that: the holding part has a positioning part for positioning and holding the slider; , in the state where the slider is held by the positioning portion, when a lateral pull force in the width direction of the belt acts, the lateral pull abutment body abuts against a flange disposed on the slider and is held. In this slider, the end portions on the meshing side of the first fastener stringer and the second fastener stringer are expanded to relatively rotate and move the pull-out member with respect to the holding member. , the horizontal pull abutment body is pulled out from the rear opening of the slider.

Moreover, it is preferable that the said holding member has the slider holding part for holding the said slider to the 2nd fastener stringer, and the said positioning part is formed in the said slider holding part.

Moreover, it is preferable that the said holding member has the positioning raised part as the said positioning part, and the said positioning raised part abuts on the inner surface of at least one of the upper and lower fins in the said slider. Alternatively, the holding member may also have a positioning protrusion as the positioning portion, and the positioning protrusion abuts against a guide column that connects the upper and lower fins in the slider, or the holding member may also have As the positioning portion, an insertion portion into which a stop claw arranged in the slider is fitted may be provided.

In addition, it is preferable that at least one of the pull-out member and the holding member has a flared convex portion, and the flared convex portion is disposed between the guide post and the rear of the slider that are positioned and held. between the openings and protrude from opposite end edges of the first or second zipper strings toward opposite end edges of the opposite zipper string.

In addition, it is preferable that the pull-out member has an expanded reinforcement portion, and/or the holding member has an expanded reinforcement portion, and the expanded reinforcement portion of the pull-out member is positioned at the position to be held. The guide passage of the slider extends integrally with the lateral pull abutment body along the opposite edge of the first fastener stringer on the side of the engaging sliding end, and the holding member is The expanded reinforcing part is arranged along the opposite end edge of the engaging slide end side of the second fastener stringer, and the expanded reinforcing part on the first fastener stringer side can be Formed by the thickness of the belt passing through the passage formed by the end edge of the flange.

In this case, it is preferable that the pull-out member has a tape reinforcement formed on the fastener tape surface in the vicinity of the slider positioned and held, and the tape reinforcement is connected to the fastener tape. The transverse tension abutment body and the expanded reinforcement part are connected into one body.

The other end of the head holding portion is integrally connected to the front stop portion.

The effect of the invention

In the slide fastener of the present invention, the holding member is arranged at the meshing-side end portion of the meshing element row of the second fastener stringer, and the pull-out member is arranged on the first fastener stringer so as to face the holding member. In addition, the holding member has a positioning portion for positioning and holding the slider at its engaging sliding end. Therefore, when the slide fastener is quickly opened without the sliding operation of the slider, it is possible to prevent the rotation of the end portions on the side of the meshing sliding end portion of the first and second fastener stringers on the left and right in the expanding direction. The case slider moves toward the separation slide end side.

In addition, the pull-out member has a lateral pull abutment body at the end of the engaging element row side, and the horizontal pull abutment disposed in the pull-out member is positioned in a state where the slider is positioned and held at the engaging sliding end. The body is in a state in which it protrudes from the flange rear end of the slider to the depth of the engaging element guide passage by a predetermined amount. Thus, for example, for a slide fastener, even if a lateral pull force in the tape width direction acts to separate the holding member and the pull-out member, the slide fastener is held in the slider because the lateral pull abutting body abuts against the flange of the slider. , so that the zipper can withstand the specified transverse tension.

On the other hand, when the ends of the left and right first and second fastener stringers on the meshing slide end side are expanded, the pull-out member is relatively rotated and moved in the direction of expansion in the plane of the fastener tape with respect to the holding member. In the case of the slide fastener, the horizontal pull abutment body can be rotated to release the engagement in the meshing element guide passage of the slide fastener, and the rotated horizontal pull abutment body can be pulled out from the rear opening of the meshing element guide path. In particular, in this case, it is preferable that the horizontal pull abutment body has a dimension width in the belt length direction that can rotate while slidingly contacting the flange of the slider when the pull-out member rotates, thereby enabling the horizontal pull The abutting body is easily pulled out from the rear opening of the slider.

In addition, even if the slider moves slightly away from the engaging sliding end to the separating sliding end, the horizontally abutting body of the first fastener stringer protrudes from the rear opening of the slider toward the depth of the engaging element guide passage. Then, even when the pull-out member is rotated and moved in a direction in which the end portions of the left and right first and second fastener stringers on the side of the meshing slide end are expanded, the laterally pulling abutting body cannot be moved from the rear. If the mouth is pulled out, the zipper cannot be opened.

Moreover, the said holding member has the slider holding part for holding a slider and maintaining the stopped state of this slider, and the positioning part is formed in this slider holding part. Thereby, when a slider moves to an engagement slide end part, positioning of a slider can be performed by a positioning part, and a slider can be hold|maintained more stably by a slider holding|maintenance part. Thereby, when the slide fastener is rapidly opened without sliding the slider, it is possible to more reliably prevent the slider from moving.

In addition, the holding member has a positioning raised portion as a positioning portion, and the positioning raised portion abuts against the inner surface of the upper fin or the inner surface of the lower fin in the slider, so that even when the pull-out member is moved toward the holding member Even in the case of rotational movement in the expanding direction, the slider can be stably positioned and held at the engaging sliding end.

In addition, the holding member also has a positioning convex portion as a positioning portion that abuts against the guide post of the slide fastener, or an embedded portion as a positioning portion that is inserted into the stop pawl disposed in the slider, thereby Even when the pull-out member is rotationally moved in the expansion direction relative to the holding member, the slider can be stably positioned and held at the engaging slide end.

In addition, at least one of the pull-out member and the holding member has a flared convex portion disposed between the guide post and the rear opening of the slider positioned and held at the engaging sliding end portion, and extends from the first slide fastener to the rear opening. The opposite edge of the fastener stringer or the second fastener stringer protrudes toward the opposite end edge of the opposite fastener stringer, so that the operation when the slider is slid to the side of the separation sliding end to perform a normal closing operation can be reduced. force.

In addition, the pull-out member has a flared reinforcing portion, and/or the holding member has a flared reinforced portion, and the flared reinforced portion of the pull-out member is in the guide path of the slider that slides toward the engaging sliding end, and along the The opposite end edge of the first zipper string is integrally extended with the lateral pull abutment body, and the expanded reinforcement portion of the holding member is extended along the opposite end edge of the second zipper string on the side of the engaging sliding end. configuration. Thereby, when rotating and moving a pull-out member to an expansion direction, deformation|transformation which arises in the fastener stringer by the side of a 1st fastener stringer can be reduced. Thereby, a predetermined opening angle can be obtained with a small amount of separation, and the slide fastener can be easily opened.

In this case, the pull-out member has a tape reinforcing portion formed on the surface of the fastener tape in the vicinity of the slider positioned and held at the sliding end portion on the engaging side, and the tape reinforcing portion is in contact with the lateral pull abutment body. It is integrated with the expanded reinforcement part. Thereby, when the slide fastener is not rapidly opened by the sliding operation of the slider, the pull-out member can be easily rotated and moved in the expanding direction, and the slide fastener can be smoothly opened.

In addition, the holding member has a front stopper for stopping the slider moved to the sliding end on the meshing side, and one end of the slider holding part is connected to the front stopper. Thereby, the holding member can be integrally formed, and the slider can be reliably stopped and held at the engaging-side sliding end portion.

In particular, when the slider holding portion functions as an expansion reinforcing portion for reinforcing the opposite edge of the second fastener stringer, when the pull-out member is rotated and moved in the expansion direction, it can be done with less effort. The amount of separation can obtain the specified expansion angle, and the zipper can be easily opened.

In addition, the holding member has a tape reinforcing portion formed on the surface of the fastener tape near the slider positioned and held at the sliding end portion on the engaging side, through which the other end portion of the slider holding portion It is integrated with the front stop part. Thereby, when the slide fastener is not rapidly opened by the sliding operation of the slider, the pull-out member can be easily rotated and moved in the expanding direction, and the slide fastener can be smoothly opened.

The handle support body 56 of the slider 50 shown in FIGS. Referring to the shape of FIG. 14 described later), it is pivotally supported by a bearing portion 56P (see FIG. 14 described later) in the front (FS direction). Therefore, the handle support body 56 can rock|fluctuate the rear (RS direction) in an up-down direction (OS-US direction) using the bearing part 56P as a fulcrum.

In the rear part (RS direction part) of the handle support body 56, the stop pawl 54 which penetrates the through hole opened in the upper flap 52 and can advance and retreat toward the element guide path 50T of the slider 50 is formed. In the state shown in FIG. 5 , the handle support body 56 is in a state in which the stop claw 54 is biased downward (US direction) by biasing mechanisms such as a leaf spring and a coil spring not shown. Further, the lowered stop claw 54 is fitted into a fitting portion 94H formed in the holding member 90 . In addition, in the state shown in FIG. 5 , the slider 50 exists at a position engaged with the front stopper 91 , and the slider 50 is positioned and held in an engaged sliding position by fitting the stopper pawl 54 into the fitting part 94H. at the end.

As shown in FIG. 3 , the rear portion (RS direction) of the guide post 50D is formed in a pointed wedge shape. Accordingly, by sliding the slider 50 backward (in the RS direction), the rows of the first engaging elements 12 and the rows of second engaging elements 13 in the engaged state introduced from the rear opening 50U into the engaging element guide passage 50T can be moved to the left and right. The direction (L-R direction) is separated, and then discharged from the brows of both sides.

In addition, if the slider 50 is slid toward the front (FS direction) shown in FIG. The rows of first and second engaging elements 12 and 13 that are guided and merged by the edges 50F to be in an engaged state are discharged from the rear port 50U.

Next, the function of each part formed in the drawer member 80 is demonstrated using FIGS. 3-5. The expanded reinforcing portion 82 formed on the opposite end edge side along the core portion 14 of the first fastener stringer 16 is inserted through the engaging element guide passage 50T in a state where the slider 50 is disposed at the engaging sliding end portion. The part where the rigidity in the vicinity of the core part 14 is improved.

Since the expanded reinforcing portion 82 is formed, the rigidity near the core portion 14 is improved. Therefore, when the slider 50 is arranged at the engaging sliding end portion, when the first and second left and right sides are aligned within the plane of the fastener tape 11, When the ends of the two fastener stringers 16 and 17 on the meshing slide end side are spread apart and the pull-out member 80 is relatively rotated in the spreading direction with respect to the holding member 90 , deformation of the core 14 can be suppressed.

Therefore, a predetermined spread angle can be obtained with a small amount of separation between the first and second fastener stringers 16 and 17, and the lateral pull abutment body 86 can be easily moved from the meshing element guide passage 50T to a predetermined opening angle. Pull out the rear port 50U. Therefore, the 1st and 2nd fastener stringer 16,17 can mutually spread easily.

As shown in FIG. 5 , the thickness of the expanded reinforcing portion 82 in the vertical direction (OS-US direction) is set to be thinner than the gap in the vertical direction (OS-US direction) of the belt insertion passage 50G. Therefore, the flared reinforcing portion 82 can be inserted and removed from the Y-shaped engagement element guide passage 50T in plan view through the belt insertion passage 50G.

As shown in FIG. 3 , the expanded convex portion 83 protruding from the core portion 14 of the first fastener stringer 16 to the opposite end edge side is inserted through the engaging element in the state where the slider 50 is disposed at the engaging sliding end. The part inside the guide passage 50T. When the slider 50 is slid backward (in the RS direction) from the engaging sliding end, the expanded convex portion 83 is first in contact with the guide post 50D compared with the first engaging element 12, thereby playing the role of moving the first fastener stringer 16 to the rear. The left side (L direction) is greatly expanded.

Since the flared convex portion 83 protrudes from the core portion 14 of the first fastener stringer 16, when the slide fastener 50 is slid backward (RS direction) from the engaging sliding end, the amount of damage to the first fastener stringer can be reduced. The guide post 50D collides with the first engaging member 12 in a state where the 16 is insufficiently expanded, resulting in an increase in sliding resistance and deterioration of the operational feeling.

The lateral pull abutment body 86 mounted on the opposite end edge of the front (FS direction) of the first fastener stringer 16 of the first fastener element 12 row is arranged on the side of the first fastener element 12 row of the pull-out member 80 The end portion of the slider is a portion inserted into the engaging element guide passage 50T in a state where the slider 50 is disposed at the engaging and sliding end portion.

As shown in FIG. 4 , the thickness in the vertical direction (OS-US direction) of the lateral tension abutment body 86 is set to be thicker than the gap in the vertical direction (OS-US direction) of the belt insertion passage 50G and to be thicker than that of the expanded reinforcement portion. 82 thick. Therefore, in a state where the core 14 is inserted along the Y-shaped engaging element guide passage 50T in a plan view, the lateral tension abutment body 86 abuts against the flange 50F from the inside, so that the horizontal tension abutment body 86 does not It falls out of the tape insertion passage 50G of the slider 50 . Thereby, it can receive predetermined lateral pulling force (horizontal pulling force) when pulling the 1st and 2nd fastener stringer 16, 17 mutually in the left-right direction (direction which pulls away from each other).

As shown in FIG. 3 , on the edge of the flange 50F side of the lateral tension abutment body 86 , when the lateral tension abutment body 86 moves to the left (L direction), a portion capable of abutting against the inner wall of the flange 50F is provided. The range is defined as the lateral tension contact range Lw (see the enlarged view of FIG. 9 described later). In addition, the rear (RS direction) end of the flange 50F is defined as the flange rear end 50R. In addition, the distance from the flange rear end 50R to the front (FS direction) of the lateral pull abutment range Lw in the state where the slider 50 is arranged at the engaging sliding end is defined as the lateral pull resistance engagement dimension. Ls.

By keeping the horizontal pull-resistant engaging dimension Ls within a predetermined size range, the contact body 86 and the foremost second engaging element 13 can be connected by laterally pulling the abutting body 86 in the state where the slider 50 is disposed at the end of the engaging slide. Engage, or abut against the flange 50F from the inside to receive a predetermined lateral tensile force.

In addition, as described later using FIG. 8 and FIG. 9 , when the meshing and sliding end portions of the left and right first and second fastener stringers 16 and 17 are rotated in the direction of expansion within the plane of the fastener tape 11 In the case where the lateral pull abutment body 86 is rotated in the engaging element guide passage 50T of the slider 50, the engagement with the second engaging element 13 can be released, and the lateral pull abutment body 86 can be moved out of the engaging element guide passage 50T. Pull out the rear port 50U.

In addition, with regard to the size range of the horizontal pull-resistant engagement dimension Ls, when the installation pitch of the first and second engaging elements 12, 13 is defined as P, it is preferable to set the horizontal pull-resistant engagement dimension Ls at P/ 6≤Ls≤5P/6. The installation pitch P refers to the predetermined interval between the engaging elements mounted on the same fastener tape 11, for example, the center position in the front-rear direction (FS-RS direction) of the engaging elements 12, 13, and the adjacent engaging elements 12, 13 can be arranged. The dimension between the same positions of the engaging elements 12, 13 is taken as the installation pitch P.

In this case, when the lateral pull-resistant engaging dimension Ls is smaller than P/6, the lateral pull-resistant force is low, and there is a high possibility that the slide fastener 10 will be separated randomly. On the other hand, when the horizontal pull-resistant engagement dimension Ls exceeds 5P/6, even if the left and right first and second fastener stringers 16, 17 in the front (FS direction) of the slide fastener 10 are engaged and slide end sides There is also a high possibility that the lateral pull abutment body 86 may be difficult to pull out from the rear opening 50U of the engaging element guide passage 50T when they are rotated in the expanding direction.

On the first zipper stringer 16, the connecting reinforcing part 85 connecting the horizontally pulling abutting body 86 and the expanding reinforcing part 82 and connecting them as one is used to further expand the expanding reinforcing part 82 and the horizontally pulling abutting body 86. Reinforcing part firmly mounted on the zipper tape 11. In addition, by forming the connection reinforcement part 85 on the first fastener stringer 16, in the state where the slider 50 is arranged at the meshing sliding end, the left and right first and second fastener stringers 16, 17 are aligned. When the ends on the side of the meshing sliding end are rotated in the expanding direction, the deformation of the fastener tape 11 can be suppressed, and therefore, the amount of separation of the first and second fastener stringers 16, 17 can be specified by a small amount. Therefore, the lateral pull abutment body 86 can be easily pulled out from the rear opening 50U of the engaging element guide passage 50T.

In addition, the connection reinforcing portion 85 has a thickness corresponding to the portion where the flange 50F passes (that is, on the lower side of the portion where the flange 50F passes) so as not to interfere with the flange 50F of the slider 50 than the belt insertion passage 50G. In addition, in order to improve the strength and rigidity of this part, the thickness of the part (left and right (L-R direction) sides of the slider 50) that does not pass the flange 50F of the slider 50 is increased, so that This part is thicker than the expanded reinforcement part 82 (refer FIG. 4 and FIG. 5). In addition, the thickness of the portion where the flange 50F does not pass in the connection reinforcement portion 85 is set to be thinner than that of the lateral tension abutment body 86 .

An engagement end 87 extending rearward (in the RS direction) in a hook shape for engaging with the engagement head of the second engagement element 13 is formed on the opposite edge side of the transverse tension abutment body 86 . By forming the meshing end 87 on the horizontal pull abutment body 86, when the left and right first and second fastener stringers 16, 17 are rotated in the expanding direction, the meshing end 87 is aligned with the opposing second meshing element 13. The surrounding movement of the meshing head thereby promotes the rotation of the expansion direction, therefore, a predetermined expansion angle can be obtained by a small amount of separation between the first and second fastener stringers 16, 17, so that the The lateral pull abutment body 86 is easily pulled out from the rear opening 50U of the engaging element guide passage 50T.

Next, the function of each member formed on the holding member 90 will be described using FIGS. 3 to 5 . The front stop portion 91 arranged further forward (in the FS direction) of the front termination end of the second meshing element 13 row on the second fastener stringer 17 contacts a part of the slider 50 so that the slider 50 is engaged. The part where the slide end stops. In the embodiment shown in FIG. 3, since the outer dimension of the front stopper 91 in the vertical direction (OS-US direction) is set thicker than the inner dimension of the engaging element guide passage 50T in the vertical direction (OS-US direction), Therefore, the front stop portion 91 is in an engaged state without entering into the engaging element guide passage 50T.

In addition, other structures can be used instead of the embodiment in which the front stopper 91 is set thicker than the inner dimension of the engaging element guide passage 50T as shown in FIG. 3 . For example, as shown in FIG. 19 described later, the front stopper 491 can also be inserted into the engagement element guide passage 50T by setting the front stopper 491 thinner than the inner dimension of the engagement element guide passage 50T, and by making The rear edge portion (the edge portion in the RS direction) of the front stop portion 491 abuts on the front end portion (the end portion in the FS direction) of the flange 50F of the slider 50 to stop the slider 50 at the meshing and sliding end portion.

As shown in FIG. 4 and FIG. 5 , the slider holding portion 92 arranged in front (FS direction) of the front termination end of the second engaging element 13 row on the second fastener stringer 17 is along the second fastener chain. The opposite side edge of the belt 17 is formed, and the front end of the slider holding portion 92 is connected to the front stop portion 91 .

The slider holding portion 92 is set so that its thickness in the vertical direction (OS-US direction) is thicker than the gap in the vertical direction (OS-US direction) of the tape insertion passage 50G, and is thicker than the vertical direction of the engaging element guide passage 50T. (OS-US direction) inner dimension is thin. Therefore, when the slider holding portion 92 is inserted into the engaging element guide passage 50T of the slider 50, the slider holding portion 92 can hold the slider 50 on the second fastener stringer 17 and maintain the slider. 50 stop states.

In addition, in the state where the slider holding portion 92 is inserted into the engaging element guide passage 50T, since the right side (R direction) end of the slider holding portion 92 abuts against the flange 50F from the inside, it does not come from the 50G drop off with interspersed passage. Thereby, even in the state which pulled out the 1st fastener stringer 16 from the slider 50, the slider 50 can be hold|maintained by the 2nd fastener stringer 17 side.

The two expanding protrusions 93 protruding from the core 14 of the second fastener stringer 17 toward the opposite edge side are inserted into the engaging element guide passage 50T in a state where the slider 50 is disposed at the engaging sliding end. part. When the slider 50 is slid backward (RS direction) from the engaging sliding end, the expanded convex portion 93 is first in contact with the guide column 50D compared with the second engaging element 13, thereby playing a role in making the second fastener stringer 17 move toward the rear side. The effect of large expansion on the right side (R direction).

The connection reinforcement part 95 connecting the front stop part 91 and the rear end part of the slider holding part 92 of the second fastener stringer 17 is for attaching the front stop part 91 and the slider holding part 92 to the fastener tape 11 more firmly. reinforcement parts. In addition, by forming the connection reinforcement part 95 on the second fastener stringer 17, in the state where the slider 50 is arranged at the meshing sliding end, the left and right first and second fastener stringers 16, 17 are aligned. The deformation of the fastener tape 11 can be suppressed when the end parts on the meshing slide end part side rotate in the expanding direction. Therefore, a predetermined expansion angle can be obtained with a small amount of separation between the first and second fastener stringers 16 and 17, so that the lateral pull abutment body 86 can be opened from the rear opening of the engaging element guide passage 50T. 50U pulls out easily.

In addition, the connection reinforcement part 95 has a part thinner than the belt insertion path 50G on the lower side of the part where the flange 50F passes so as not to interfere with the flange 50F of the slider 50. In addition, in order to increase the strength and rigidity of this part, Increase the thickness of the portion where the flange 50F of the slider 50 does not pass over it (the left and right (L-R direction) sides of the slider 50) is increased compared to the portion where the flange 50F passes over it (refer to FIG. 4 and Figure 5.).

A fitting portion 94H is opened on the upper surface (surface in the OS direction) of the rear portion (RS direction) of the slider holding portion 92 . In the state where the slider 50 is arranged at the meshing slide end, by fitting the stop claw 54 on the slider 50 side into the fitting part 94H, the slider 50 can be positioned and held at the meshing slide end. For example, if the meshing sliding end sides of the first and second fastener stringers 16, 17 on the left and right are rotated in the expanding direction, the slider 50 will move backward (RS direction) along with the expanding operation. )move.

At this time, even if the slider 50 moves slightly backward (in the RS direction), the distance from the rear end 50R of the flange to the front end of the lateral pull abutment range Lw (the horizontal pull resistance engagement dimension Ls shown in FIG. will increase. If the lateral pull-resistant engagement dimension Ls becomes longer, the lateral pull abutment body 86 cannot be pulled out from the rear opening 50U of the engaging element guide passage 50T. Therefore, in the embodiment shown in FIGS. 1 to 5 , by fitting the stop pawl 54 on the side of the slider 50 into the fitting portion 94H, the slider 50 can be positioned at the end of the engagement slide, and the horizontal pull resistance can be improved. The engaging size Ls is within the specified size range.

In addition, the structure for positioning the slider 50 at the meshing slide end part is not limited to the structure which fits the stopper claw 54 in the fitting part 94H as shown in FIGS. 1-3, Another structure can also be used. For example, as described later using FIGS. 13 and 14 , it is also possible to form an upper wing for engaging with the inside of the engaging element guide passage 50T in the vertical direction (OS-US direction) from the slider holding portion 92 . The positioning raised portion 94B (positioning portion) that the piece 52 and/or the lower wing piece 53 abuts against, thereby positioning and holding the slider 50 at the engaging sliding end.

In addition, as described later using FIG. 20 , the positioning convex portion 94C (positioning portion) that contacts the guide post 50D in the engaging element guide passage 50T is positioned toward the first and second fastener stringers 16 and 617 . The protruding side of the opposite end edge also enables the slider 50 to be positioned and held at the engaging sliding end. In addition, the positioning portion is a member that performs positioning of the slider 50 so that the slider 50 does not accidentally move backward when the slider 50 is moved to the engaging slide end.

Since the above-mentioned positioning portion is integrally formed with the slider holding portion 92, when the slider 50 is pulled out in a state where the slider 50 is positioned, the slider 50 can be stably held, so that the puller 80 can be pulled out from the slider. The slider 50 is surely pulled out. In addition, in order to stably hold the slider 50, the slider holding portion 92 is preferably formed such that, in a state where the slider holding portion 92 is inserted into the slider 50, the length in the tape length direction is larger than that of the slider 50. The length from the shoulder 50S to the end of the guide post 50D on the rear port 50U side is long.

Next, a state in which the meshed engagement element rows are separated while sliding the slider 50 backward (RS direction, direction to separate the sliding end) will be described with reference to FIGS. 6 and 7 . FIG. 6 shows a state in which the slider 50 is arranged at the meshing sliding end and the slider 50 is slightly slid backward (RS direction) so that the left and right first and second fastener stringers 16, 17 are slightly expanded. A top sectional view of the zipper shown. 7 is a top cross-sectional view of the slide fastener showing a state in which the engaging element rows in the engaged state are sequentially separated by sliding the slider further rearward (RS direction) from the state shown in FIG. 6 . In addition, the same parts as those already described in FIGS. 1 to 5 are given the same reference numerals, and description thereof will be omitted.

In the state where the slider 50 is arranged at the end of the meshing slide, if the user pinches the handle 59 and applies a force to the rear (RS direction), the stop pawl 54 that has been biased downward (US direction) by the spring mechanism will move upward. side (OS direction) movement. This structure is a well-known slider structure generally called an automatic slider (Automatic Slider) or a semi-automatic slider (semi-Automatic Slider) (see FIG. 5 ). When the stop claw 54 moves upward (OS direction), the stop claw 54 will disengage from the fitting part 94H, and the slider 50 will become the slidable state from the state positioned at the meshing slide end part. When the user moves the handle 59 backward (RS direction), the slider 50 also moves backward (RS direction).

As shown in FIG. 6 , if the slider 50 is slid backward (RS direction) from the meshing sliding end, the rear end of the guide post 50D in the slider 50 first meets the inclined surface of the expanded convex portion 93 of the holding member 90. contact, and expand the second fastener stringer 17 to the right (R direction). Then, the top of the opposite edge side on the expanded convex portion 93 moves toward the shoulder 50S while sliding on the right side of the guide post 50D, thereby further expanding the second fastener stringer 17 to the right (R direction). .

When the slider 50 is further slid backward (in the RS direction), the rear end of the guide post 50D abuts against the slope of the expanded convex portion 83 of the pull-out member 80, and the first fastener stringer 16 is turned to the left. (L direction) expand. Then, the top of the opposite end edge side of the expanding convex portion 83 moves toward the shoulder 50S while sliding on the left side of the guide post 50D, whereby the first fastener stringer 16 is further expanded to the left (L direction). .

If the slider 50 is further slid backward (in the RS direction), the slopes of the engaging heads of the left and right first and second engaging elements 12 and 13 will sequentially abut against the rear ends of the guide posts 50D, thereby making the first And the second fastener stringers 16, 17 are expanded sequentially.

If the expansion protrusions 83, 93 are not formed on the opposite end edges of the first and second fastener stringers 16, 17, the expansion of the left and right first and second fastener stringers 16, 17 is insufficient. Next, the guide post 50D abuts against the front (FS direction) side surfaces of the engagement heads of the first and second engagement elements 12 and 13 . Then, the sliding resistance of the slider 50 is increased, thereby deteriorating the operating feeling.

As described above, the first and second engaging elements 12 and 13 in the engaged state are introduced into the engaging element guide path 50T from the rear port 50U, and the first and second engaging elements 12 and 13 are guided by the guide post 50D. After the rows are separated in the left and right direction (L-R direction), they are discharged from both shoulders 50S.

Next, using FIGS. 8 to 12 , the left and right first and second fastener stringers 16 , 17 are placed in a state where the slider 50 is disposed on the meshing sliding end of the slide fastener 10 so as not to slide. The operation in the case where the meshing slide end sides of the slide fastener 10 are quickly separated by rotating in the expanding direction will be described.

FIG. 8 is a view from the state shown in FIG. 3 to rotate the engaging sliding end sides of the left and right first and second fastener stringers 16 and 17 in the expanding direction so that the horizontally pulling abutting body 86 is pulled from the slider 50. The top sectional view of the slide fastener 10 which shows the state which pulled out the rear opening 50U. FIG. 9 is a top cross-sectional view illustrating the vicinity of the lateral tension contact body 86 shown in FIG. 8 in an enlarged manner. Fig. 10 is a sectional view taken along the line X-X shown in Fig. 9 . Fig. 11 is a planar sectional view of the slide fastener 10 showing a state in which the left and right first and second fastener stringers 16, 17 are further separated from the state shown in Figs. 8 and 9 . FIG. 12 is a plan view illustrating the separation insert 39 installed at the separation slide end portion of the slide fastener 10 . In addition, the same parts as those already described in FIGS. 1 to 5 are given the same reference numerals, and description thereof will be omitted.

As shown in FIG. 3 , in the state where the slider 50 is arranged at the engaging sliding end, even if a lateral pulling force is applied to pull the first and second fastener stringers 16 and 17 in parallel in the left-right direction, the lateral pull will The contact body 86 is also held in the slider 50 by abutting against the flange 50F from the inside, so that the meshed state of the rows of the first and second meshing elements 12 and 13 can be maintained.

And as shown in FIGS. 8 to 10, in the state where the slider 50 is disposed at the engaging sliding end, if the engaging sliding end sides of the first and second fastener stringers 16, 17 are spread apart from each other, and When the pull-out member 80 is relatively rotated and moved in the expansion direction with respect to the holding member 90 , the expansion reinforcing portion 82 formed thinner than the gap of the belt insertion passage 50G is pulled out from the belt insertion passage 50G. At the same time, the lateral tension abutment body 86 is rotated while slidingly contacting the flange 50F of the slider 50, and the horizontal tension abutment body 86 is pulled out from the rear opening of the engaging element guide passage 50T. At this time, since the engagement between the engagement end 87 and the second engagement element 13 is released by the rotation of the abutment body 86, the engagement elements in the engaged state can be separated sequentially toward the rear (RS direction). state. By doing so, the slide fastener 10 can be quickly detached.

If the engagement of all the first and second engaging elements 12 and 13 in the slide fastener 10 is disengaged to become a separated state, then as shown in FIG. 32 Rotate in the direction to expand the front (FS direction) while being supported by the shaft. Then, the shaft part 32 of the insertion body 30 can be detached from the to-be-embedded body 40, and the 1st and 2nd fastener stringers 16 and 17 on either side can be separated from each other.

In addition, since the stop claw 54 on the side of the slider 50 is fitted into the fitting portion 94H of the second fastener stringer 17 , even when the left and right first and second fastener stringers 16 and 17 are meshed, Even when a force is applied in a direction in which the sides of the sliding ends spread apart, it is possible to prevent the slider 50 from moving backward (in the RS direction) while being entrained. Thereby, the slider 50 can be positioned and held at the engaging sliding end.

In addition, as shown in FIG. 9 , if the meshing sliding end sides of the first and second fastener stringers 16 and 17 are rotated in the expanding direction, the meshing end 87 will move along the meshing of the opposing second meshing element 13 . The periphery (side wall surface) of the head moves to promote the rotation of the laterally pulled abutting body 86 . Thereby, a predetermined opening angle can be obtained with a small distance between the first and second fastener stringers 16 and 17 .

Next, another embodiment for positioning and holding the slider 50 at the engaging sliding end will be described with reference to FIGS. 13 and 14 . FIG. 13 is a top cross-sectional view of the slide fastener illustrating an example in which positioning protrusions 94B contacting the upper flap 52 and/or the lower flap 53 from inside are formed on the slider holding portion 92 . FIG. 14 is a cross-sectional view taken along the arrow XIV shown in FIG. 13 , and is a cross-sectional view showing a state where the positioning raised portion 94B is in contact with the upper fin 52 and the lower fin 53 in the guide passage 50T. In addition, the same parts as those already described in FIGS. 1 to 5 are given the same reference numerals, and description thereof will be omitted.

The 1st fastener stringer 16 in the slide fastener 110 shown in FIG. 13 and FIG. 14 has the structure similar to what was demonstrated in FIGS. 1-5. The front stop part 91, the slider holding|maintenance part 92, the expansion convex part 93, and the connection reinforcement part 95 in the 2nd fastener stringer 117 have the structure similar to what demonstrated in FIGS. 1-5. In the embodiment shown in FIG. 13 and FIG. 14 , instead of the fitting portion 94H shown in FIG. 1 to FIG. 11 , it is configured as follows. The positioning raised portion 94B abutting against the upper fin 52 and/or the lower fin 53 in the engaging element guide passage 50T positions and holds the slider 50 at the engaging sliding end. With such a configuration, the slider 50 can also be positioned and held at the engaging and sliding end, and the lateral pull-resistant engaging dimension Ls can be kept within a predetermined dimension range.

By keeping the horizontal pull-resistant engagement dimension Ls within a specified size range, the slider 50 can withstand a specified horizontal pull force in the state where the slider 50 is arranged at the engaging sliding end, and the left and right first and second fastener elements When the meshing and sliding end portions of the fastener tapes 16 and 117 are rotated in the expanding direction in the plane of the fastener tape 11, the lateral pull abutment body 86 can be pulled out from the rear opening 50U of the engaging element guide passage 50T, thereby The zipper 110 separates quickly.

Moreover, the swing fulcrum of the handle support body 56 is demonstrated using FIG. 14. FIG. The starting end part 56B which supports the handle support body 56 swingably protrudes from the upper wing piece 52 of the slider 50 front part (FS direction). Pivot-shaped bearing portions 56P are formed at both left and right end portions (side portions in the L-R direction) of the starting end portion 56B. The handle support body 56 is supported in a swingable manner relative to the starting end portion 56B with the bearing portion 56P as a fulcrum, and further, the stop pawl 54 of the handle support body 56 (refer to FIG. ) are spring-pressed in the direction of entering and exiting the engaging element guide passage 50T.

Next, another embodiment for positioning and holding the slider 50 at the engaging sliding end will be described using FIG. 15 . FIG. 15 illustrates an embodiment in which the slider 50 is positioned and held at the end of the engagement slide by locking the stop pawl 54 on the side of the slider 50 on the front (FS direction) end edge of the flared convex portion 293. picture. In addition, the same parts as those already described in FIGS. 1 to 5 are given the same reference numerals, and description thereof will be omitted.

The 1st fastener stringer 16 in the slide fastener 210 shown in FIG. 15 has the structure similar to what was demonstrated in FIGS. 1-5.

The first and second zipper stringers 416, 417 of the slide fastener 410 shown in FIGS. It is formed by sewing on the opposite edge of a pair of left and right slide fastener tapes 11. In the slide fastener 410, the first and second engaging elements 412, 413 are inserted through the slider 50, and the first and second engaging elements are formed by sliding the slider 50 in the front-rear direction (FS-RS direction). The zipper 410 is opened and closed by engaging and separating the rows 412 and 413 from each other.

As shown in FIGS. 18 and 19 , the first fastener stringer 416 has: a fastener tape 11 formed with a core 14 at opposite end edges; a row of first engaging elements 412 mounted on opposite end edges of the fastener tape 11; The pullout member 480 attached to the front (FS direction) of the first engaging element 412 row; and the reinforcement piece 24 (tape reinforcement) for improving the rigidity of the fastener tape 11 near the attachment position of the pullout member 480 .

The pull-out member 480 is made up of the following parts: the expansion reinforcement part 482 installed on the reinforcement piece 24 of the fastener tape 11; the expansion protrusion 483 protruding from the expansion reinforcement part 482 to the opposite edge side; The horizontal tension abutment body 86 formed on the opposite end edge of the front (FS direction) of the element 412 row; In addition, an engaging end 87 for engaging with the engaging head of the opposing second engaging element 413 is formed on the opposite end edge side of the lateral pull abutment body 86 .

In addition, the second fastener stringer 417 is composed of the following components: the fastener tape 11 formed with the core 14 at opposite end edges; 413 row; and a holding member 490 installed in front of the second engaging element 413 row (FS direction).

The holding member 490 is composed of a front stop portion that stops the slider 50 at the engaging sliding end by abutting against a part of the slider 50 (abutting against a flange 50F in the embodiment shown in FIG. 19 ). 491 ; the slider holding part 492 attached to the second fastener stringer 417 in a shape covering the core part 14 ; and the expansion convex part 493 protruding from the slider holding part 492 to the opposite edge side. In addition, similarly to the embodiment shown in FIGS. 1 to 5 , a fitting portion 94H formed as a concave portion having a quadrilateral shape in plan view is opened above the rear portion of the holding member 490 (in the OS direction).

As shown in FIG. 18 and FIG. 19 , on the end edge of the flange 50F side of the lateral pull contact body 86 , when the lateral pull contact body 86 moves to the left (L direction), the inner wall of the flange 50F can be aligned. The contact range is defined as the horizontal pull contact range Lw. In addition, the rear (RS direction) end of the flange 50F is defined as the flange rear end 50R. In addition, the distance from the flange rear end 50R to the front (FS direction) of the lateral pull abutment range Lw in the state where the slider 50 is arranged at the engaging sliding end is defined as the lateral pull resistance engagement dimension. Ls.

As shown in FIGS. 18 and 19 , when the first and second engaging elements 412 and 413 rows composed of helical single filaments are used in the slide fastener 410 , by shrinking the horizontal pull-resistant engagement dimension Ls Within the specified size range, when the slider 50 is disposed at the end of the engagement slide, the abutment body 86 engages with the frontmost second engagement element 413 due to the horizontal pull, or abuts against the flange 50F from the inside. Connected, so it can also withstand the specified transverse tension. In this case, it is preferable to set the lateral pull-resistant engagement dimension Ls within the range of P/4.2≦Ls≦5P/4.2.

In addition, when the engaging sliding end sides of the first and second fastener stringers 416, 417 on the left and right are rotated in the expanding direction in the plane of the fastener tape 11, the engaging element guide passage of the slider 50 can be opened. The lateral pull abutment body 86 is rotated to release the mesh, and the lateral pull abutment body 86 can be pulled out from the rear opening 50U of the engaging element guide passage.

In addition, as shown in FIG. 18 and FIG. 19, by installing the reinforcing piece 24, the expanding reinforcing part 482, the connecting reinforcing part 85, or the slider holding part 492 near the engaging sliding end of the slider 50 on the fastener tape 11, The rigidity of the fastener stringer 11 can be improved, and when the slider 50 is arranged at the engaging sliding end, the engaging sliding end sides of the first and second fastener stringers 416, 417 on the left and right are widened toward each other. When the direction is rotated, deformation of the fastener tape 11 can be suppressed.

Pulls out easily. Therefore, the 1st and 2nd fastener stringer 416,417 can mutually spread easily. In addition, in order to improve the strength and rigidity of the connection reinforcement part 85, the thickness of the side of the connection reinforcement part 85 not in contact with the slider 50 (left and right (L-R direction) of the slider 50) is increased.

An engaging end 87 that engages with a part of the opposing second engaging element 413 is formed on the opposite end edge side of the lateral tension abutment body 86 . By forming the meshing end 87 on the horizontal pull abutment body 86, when the meshing sliding end sides of the first and second fastener stringers 416, 417 on the left and right are rotated in the expanding direction, the meshing end 87 will move along the opposite direction. The surrounding movement of the engaging head of the second engaging element 413 facilitates the rotation of the laterally pulling abutment body 86 . Accordingly, a predetermined spread angle can be obtained with a small amount of separation between the first and second fastener stringers 416, 417, and the lateral pull abutment body 86 can be opened from the rear opening 50U of the engaging element guide passage. Pulls out easily. Therefore, the 1st and 2nd fastener stringer 416,417 can mutually spread easily.

Moreover, in the Example shown in FIG. 18 and FIG. 19, the expansion convex part 483 and the expansion convex part 493 protrude along the opposite edge of the fastener tape 11, and mutually deviate in the front-back direction. Constructing the expansion protrusion 483 and the expansion protrusion 493 in this way, when the slider 50 is slid backward (RS direction) from the engaging sliding end, the guide post 50D and the expansion protrusion 483 and the expansion protrusion 493 Since they are in sliding contact, the first and second fastener stringers 416, 417 can also be widely spread in the left-right direction (L-R direction). Thereby, it is possible to reduce the inconvenience that the guide post 50D collides with the first or second meshing elements 412 and 413 in a state where the first fastener stringer 16 is insufficiently expanded, resulting in an increase in sliding resistance and deterioration of the operability.

Next, another embodiment for positioning and holding the slider 50 at the engaging sliding end will be described using FIG. 20 . FIG. 20 is a diagram showing an example in which a positioning convex portion 94C abutting on the guide post 50D of the slider 50 protrudes toward the opposite end edge side of the fastener tape 11 as another example of the positioning portion. In addition, the same parts as those already described in FIGS. 1 to 5 are given the same reference numerals, and description thereof will be omitted.
