A coupling column (24) in a slider body (21) of the slider (20) has a tapered portion (24c) in which the width dimension of the coupling column (24) diminishes gradually towards a rear opening. When the slider (20) is positioned at a slide limit position, the first stopper (30) and the second stopper (40) are positioned within an accommodation region (29) that covers from a shoulder tip-side end position of the tapered portion (24c) of the coupling column (24) in the longitudinal direction to the position of the rear opening, and both stoppers come into contact with each other. This configuration makes it possible to have improved appearance quality of the slide fastener (1) in a closed state, since element attaching members (13) located on the left and right and extending from the shoulder tip of the slider (20) are be kept in a parallel or near-parallel state.

Description

Slide fastener

The present invention relates to a slide fastener having a first stop portion and a second stop portion.

Slide fasteners are often used for placket parts of clothes and pocket openings provided in clothes. Such slide fasteners are generally provided with stopping portions adjacent to at least one of both ends in the length direction of the element row to prevent the slider from falling out of the element row.

A slide fastener in which a stopper is provided adjacent to the front end portion of the left and right element rows is described in International Publication No. 2017/104007 (Patent Document 1).
For example, as shown in FIG. 5, the slide fastener 70 of Patent Document 1 includes left and right fastener stringers 71 in which element rows 73 are formed on the tape side edges of the fastener tape 72, and sliders 74 attached to the element rows 73. It has a first stop portion 75 on the left side adjacent to the front end portion of the element row 73, and a second stop portion 76 on the right side adjacent to the front end portion of the element row 73. In this case, the front-rear direction is the tape length direction of the fastener tape 72. Further, the left-right direction and the up-down direction are the tape width direction and the tape thickness direction (tape front and back directions) of the fastener tape 72, respectively.

The left first stop portion 75 provided on the slide fastener 70 of Patent Document 1 is fixed to the fastener tape 72 and has a substantially constant thickness dimension (dimension in the thickness direction), and the first stopper main body portion 75a. It has upper and lower first raised portions 75b provided at the front end portion of the first stop main body portion 75a.

Like the first stop portion 75, the second stop portion 76 on the right side includes a second stop main body portion 76a having a substantially constant thickness dimension, and upper and lower second stops provided at the front end portions of the second stop main body portion 76a. It has a raised portion 76b. Further, the first raised portion 75b and the second raised portion 76b of Patent Document 1 are formed in a shape that crosses the core cord of the fastener tape 72.

In such a slide fastener 70 of Patent Document 1, the first ridge portion 75b of the first stopper portion 75 increases the adhesive force of the first stopper portion 75 to the core cord of the fastener tape 72. Further, the second raised portion 76b increases the adhesive force of the second stopping portion 76 to the core cord of the fastener tape 72.

Therefore, even if the slider 74 comes into contact with the left and right first stop portions 75 and the second stop portion 76, it is possible to prevent or suppress the first stop portion 75 and the second stop portion 76 from being separated from the core cord. As a result, the stopping force of the first stopping portion 75 and the second stopping portion 76 with respect to the slider 74 can be increased.

International Publication No. 2017/104007

In the slide fastener 70 of Patent Document 1, when the slider 74 is brought into contact with the first stop portion 75 and the second stop portion 76 and held, for example, as shown in FIG. 5, the first fastener tape 72 on the left and right fastener tapes 72 is held. The portion in front of the stop portion 75 and the second stop portion 76 is not arranged along the front-rear direction, but is arranged so as to extend diagonally toward the outside in the width direction, thereby between the left and right fastener tapes 72. A gap 77 is formed in the space. In this case, the gap 77 between the left and right fastener tapes 72 increases as the distance from the slider 74 increases forward.

When such a slide fastener 70 is attached to, for example, a placket portion of clothes or an opening of a pocket, the slider 74 is slid until it comes into contact with the first stop portion 75 and the second stop portion 76 to close the slide fastener 70. When this is done, the fastener tape is formed in the vicinity of the first stop portion 75 and the second stop portion 76, or in the portion in front of the first stop portion 75 and the second stop portion 76 due to the opening of the fastener tape 72 described above. Wrinkles are likely to occur on the fabric of 72 and the garment, and as a result, the appearance of the garment may be deteriorated.

Further, when the slider 74 is in contact with the first stop portion 75 and the second stop portion 76, a part of the first stop portion 75 and a part of the second stop portion 76 are outside the element guide path of the slider 74. It pops out and is exposed. When the first stop portion 75 and the second stop portion 76 are partially exposed in this way, the appearance quality of a product such as clothing to which the slide fastener 70 is attached may be deteriorated.

Further, when the slide fastener 70 is attached to a product such as clothes by sewing, the gap formed between the left and right fastener tapes 72 at the time of closing is taken into consideration in order to suppress the deterioration of the appearance due to the above-mentioned wrinkles and the like. Therefore, the sewing process may be performed by a sewing machine by adding a device such as sewing a part of the fastener tape 72 in a state of being partially inclined with respect to the fabric. However, since such sewing processing requires complicated work, the attachment workability of the slide fastener 70 may be deteriorated.

Further, in the conventional slide fastener, the slider in contact with the first stop portion and the second stop portion is slid in the direction away from the first stop portion and the second stop portion (for example, the separation direction of the element row). When performing a sliding operation to move, resistance is likely to occur in the slider at the start of the sliding operation, and the operability of the slider is low in some cases.

The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to attach left and right element mounting members (for example, fasteners) when the slider is brought into contact with the left and right first stop portions and second stop portions. It is an object of the present invention to provide a slide fastener capable of preventing the tape) from opening diagonally outward from the slider in the width direction and improving the appearance quality when closed.

In order to achieve the above object, the slide fastener provided by the present invention includes a pair of first stringer members and second stringer members in which element rows are formed along opposite side edges of the left and right element mounting members. , A slider slidably attached to the element row, a first stop provided on the first stringer member adjacent to one end in the length direction of the element row, and a length direction of the element row. The slider has a second stop portion provided on the second stringer member adjacent to one end portion, and the slider has a slider body in which an upper wing plate and a lower wing plate are connected by connecting columns, and the slider body. Has an element guide path formed between the upper wing plate and the lower wing plate and communicating the left and right shoulder openings and the rear opening, and the first stop portion and the second stop portion have the slider. A slide fastener that makes contact and determines the sliding limit position of the slider, and the connecting pillar of the slider body has a symmetrical shape when viewed in a cross section parallel to the upper wing plate or the lower wing plate. When the slider is in the sliding limit position, the first stop portion and the second stop portion are formed in the above direction and have a tapered portion that gradually reduces the width dimension of the connecting column toward the rear opening. Is arranged in the accommodation area from the end position on the shoulder opening side to the position of the rear opening in the tapered portion of the connecting column in the length direction, and is characterized in that they are in contact with each other. ..

In the slide fastener according to the present invention, the first stop portion projects from the first base portion fixed to the element mounting member and the first base portion toward the second stringer member, and the first base portion. The second stop portion has a protruding portion having a thickness dimension smaller than that of the portion, and the second stop portion is provided on the second base portion and the first stop portion fixed to the element mounting member. It is preferable to have an insertion recess into which the protruding portion of the portion is inserted.

In this case, the protruding portion of the first stop portion protrudes toward the second stringer member from the center line in the width direction of the slider body in the width direction, and the second base of the second stop portion. It is preferable that a part of the portion protrudes toward the first stringer member from the center line of the slider body in the width direction.

Further, in the slide fastener of the present invention, the slider body has a stop claw portion that can be inserted and removed from the element guide path, and the stop portion is provided at the first stop portion and / or the second stop portion. It is preferable that a claw accommodating portion capable of inserting and accommodating the claw portion is provided.

In the slide fastener of the present invention having the first stop and the second stop as described above, when the slider moves to the sliding limit position, the first stop and the second stop are the element guide paths of the slider. Inside, they are arranged in the accommodation area in the longitudinal direction in contact with each other. As a result, the first stop portion and the second stop portion can be easily arranged closer to the center in the width direction in the element guide path of the slider. As a result, the element mounting member fixing the first stop and the element mounting member fixing the second stop are less likely to be bent outward in the width direction, and the left and right elements extending from the shoulder opening of the slider. It is possible to hold the mounting member in parallel or in a nearly parallel state.

Therefore, when the slide fastener of the present invention is provided on a product such as clothing, even if the slider is slid to the sliding limit position to close the slide fastener, the left and right element mounting members or the fabric of the product are left and right. It is possible to prevent or suppress the occurrence of wrinkles caused by the opening of the element mounting member. Further, when the slider is in the sliding limit position, it is possible to easily hold the opposite side edges of the left and right element mounting members in parallel or substantially parallel to each other, and the first stop portion and the second stop portion of the slider. Since it is held in the element guide path, it is not exposed to the outside. Therefore, the appearance quality of the slide fastener can be improved, and thereby the appearance quality of the product provided with the slide fastener can be improved.

Further, when the slide fastener is closed, the left and right element mounting members can be easily held straight along the length direction. Therefore, for example, the element mounting member is formed of a strip-shaped fastener tape, and the fastener tape is used. When attached to the fabric of the product by sewing, the fastener tape in a straight state can be sewn. Therefore, the slide fastener can be easily and smoothly attached.

In such a slide fastener of the present invention, the first stop portion has a first base portion fixed to the element mounting member and a protruding portion that protrudes from the first base portion and is thinner than the first base portion. The second stop portion has a second base portion fixed to the element mounting member and an insertion recess provided in the second base portion. As a result, the protruding portion of the first stop portion is accommodated in the insertion recess of the second stop portion when the slider is in the sliding limit position, and overlaps a part of the second base portion in the thickness direction. Therefore, when the slider comes into contact with the first stop portion and the second stop portion, the first stop portion and the second stop portion are easily brought into contact with each other to stably stop the slider at the sliding limit position. be able to.

In this case, the protruding portion of the first stop portion protrudes toward the second stringer member from the center line of the slider body in the width direction. Further, a part of the second base portion of the second stop portion projects from the center line of the slider body toward the first stringer member in the width direction. As a result, when the slider is slid from the sliding limit position toward the separation direction of the element row, the width of the first stop portion and the second stop portion that are in contact with each other is widened by the connecting pillar of the slider body. It can be moved outward in the direction to facilitate separation. As a result, the operability (startability) at the start of the sliding operation of the slider can be improved.

In the slide fastener of the present invention, the slider body has a stop claw portion that can be inserted and removed from the element guide path. Further, the first stop portion and / or the second stop portion is provided with a claw accommodating portion capable of inserting and accommodating the stop claw portion. As a result, the slider can be stably held at the sliding limit position, so that the slider can be prevented from sliding (naturally) due to its own weight or the like, and the closed state of the slide fastener can be stably maintained.

For example, in the case of a conventional generally known stop portion, the relative formation position of the stop portion with respect to the slider is closer to the shoulder opening of the slider than in the case of the present embodiment, and thereby the rear end of the stop portion. The part is also formed at a position close to the shoulder opening of the slider. As a result, for example, in the case of the conventional stop portion, even if the stop portion is provided with a claw accommodating portion capable of accommodating the stop claw portion of the slider corresponding to the position of the stop claw portion, the claw accommodating portion is still a stop portion. It is formed in a state of being opened rearward so as to be cut out at the rear end. However, in this case, the installation of the claw accommodating portion causes a decrease in the strength of the stopper portion. Further, since the stop claw portion inserted into the claw accommodating portion cannot be properly engaged with the second stop portion, it is difficult to properly exert the function of the stop claw portion.

On the other hand, in the slide fastener 1 of the present embodiment, when the slider 20 is held at the sliding limit position (see FIG. 2) as described later, the second stopper 40 is the accommodation area of the slider 20 described above. It is arranged only in 29 (that is, on the rear opening side of the boundary position 24e between the column intermediate portion 24b and the tapered portion 24c in the connecting column 24). As a result, when the claw accommodating portion 47 is provided in the second stopping portion 40 corresponding to the position of the stop claw portion of the slider 20, the claw accommodating portion 47 is changed to the second stopping portion in the plan view of the second stopping portion 40. It is possible to provide the 40 on the inner portion away from the outer peripheral edge (particularly the outer peripheral edge on the rear side), and as a result, it is possible to suppress a decrease in the strength of the stop portion due to the installation of the claw accommodating portion 47. Further, since the stop claw portion inserted into the claw accommodating portion 47 can be appropriately engaged with and held by the second stop portion 40, the stopped state of the slider 20 at the sliding limit position is stably maintained by the stop claw portion. it can.

The second stop portion 40 of the present embodiment has a second base portion 43 fixed to the fabric 13 and an insertion recess 44 provided in the second base portion 43. The second base portion 43 has a second base upper surface 43a and a second base lower surface 43b parallel to the upper surface and the lower surface of the fabric 13, and is between the second base upper surface 43a and the second base lower surface 43b in the second base portion 43. The thickness dimension W2 is the same as the maximum value of the thickness dimension in the fastener element 14.

The facing edge portion (inner edge portion) of the second stop portion 40 (second base portion 43) facing the first stop portion 30 is orthogonal to the plan view, bottom view, or thickness direction of the second stop portion 40. It has a second recessed portion 45 provided so as to be recessed toward the inside of the second stopper portion 40 in the cross-sectional view. The second recessed portion 45 is provided at the front end portion of the second base portion 43.

As shown in FIG. 3, it is possible to provide a gap 6 between the first stop portion 30 and the second stop portion 40 and the pillar rear end portion 24d of the connecting pillar 24.

By providing such a gap 6, for example, when the slider 20 arranged at the sliding limit position is slid backward, the connecting pillar 24 of the slider 20 becomes the first stop portion 30 and the second stop portion 30. The resistance received from 40 can be reduced, and the slider 20 can be started to slide with a lighter force. Therefore, it is possible to improve the operability at the start of the sliding operation of the slider 20.

The outer edge portion of the second base portion 43 arranged on the opposite side to the opposite edge portion has an outer surface 46 in contact with the upper flange portion 25 and the lower flange portion 26 of the slider 20 at the sliding limit position. In this case, the outer surface 46 of the second base portion 43 is arranged in parallel in the vertical direction, and the flat portion of the outer surface is the core of the fabric 13 in the plan view or the bottom view of the second stop portion 40. It is tilted with respect to the string portion 13b at an inclination angle θ2 of 10 ° or more and 30 ° or less.

The insertion recess 44 of the second stop portion 40 is formed by opening into the opposite edge portion of the second stop portion 40, and the protruding portion 34 of the first stop portion 30 is formed from the opposite edge portion side of the second stop portion 40. It can be inserted and contained. The maximum value of the thickness dimension between the upper surface and the lower surface in the portion where the insertion recess 44 of the second stop portion 40 is provided is the thickness dimension W2 of the second base portion 43 (that is, the insertion recess of the second base portion 43). It is 20% or more and 50% or less of the thickness dimension between the upper surface 43a of the second base and the lower surface 43b of the second base in the portion where 44 is not provided. As a result, the strength of the second base portion 43 can be appropriately secured, and the protruding portion 34 of the first stop portion 30 can be smoothly inserted and accommodated.

In the slide fastener 1 of the present embodiment having the first stop portion 30 and the second stop portion 40 described above, for example, a sliding operation in which the slider 20 at the position shown in FIG. 1 is slid forward by pulling a pull tab (not shown). By performing the above, the slider 20 can be moved to the sliding limit position (sliding front limit position). In this case, the sliding limit position of the slider 20 is the stop of the slider 20 in which the slider 20 comes into contact with the first stop portion 30 and the second stop portion 40 and cannot move forward (element closing direction) any more. Say the position.

When the slider 20 slides to the sliding limit position in this way, the first stop portion 30 and the second stop portion 40 enter the element guide path 28 from the shoulder opening of the slider body 21, and the slider body 21 It moves to the region on the rear opening side of the boundary position 24e on the connecting column 24.

Further, the protruding portion 34 of the first stopping portion 30 is inserted and accommodated in the insertion recess 44 of the second stopping portion 40, and the protruding portion 34 of the first stopping portion 30 and a part of the second base portion 43 (the first). 2 The upper half portion 41a) arranged on the upper side of the insertion recess 44 of the stop portion 40 overlaps with each other in the thickness direction. Further, the first stop portion 30 and the second stop portion 40 are in contact with each other, and the first stop portion 30 and the second stop portion 40 are in contact with the upper flange portion 25 and the lower flange portion 26 of the slider body 21, respectively. To do. As a result, the slider 20 can be stably stopped at the sliding limit position.

At this time, the first stop portion 30 and the second stop portion 40, which are in contact with each other, are in the accommodation area 29 in the length direction (that is, in the middle of the pillars of the connecting pillar 24) with respect to the element guide path 28 of the slider body 21. (In the region behind the boundary position 24e of the portion 24b and the tapered portion 24c). In this way, the first stop portion 30 and the second stop portion 40 move relative to the position rearward of the slider body 21 to stop the slider 20, so that the first stop portion 30 and the second stop portion 40 are stopped as in Patent Document 1. Compared with the case where the stop portion and the second stop portion are arranged on one side of the boundary position between the column intermediate portion and the taper portion of the connecting column (see, for example, FIG. 5), the first stop portion 30 and the second stop portion 30 and the second stop portion. The portion 40 can be arranged closer to the center in the width direction in the element guide path 28 of the slider 20. In other words, the distance between the first stop portion 30 and the second stop portion 40 in the width direction can be narrowed.

Thereby, the core cord portions 13b of the left and right fabrics 13 can be held in a state parallel to or close to parallel to each other. Therefore, it is possible to make it difficult for the left and right fabrics 13 to be bent outward in the width direction, thereby making it difficult for the left and right fabrics 13 to wrinkle. Further, the first stop portion 30 and the second stop portion 40 can be held in the element guide path 28 of the slider 20 and hidden from the outside of the slider 20. As a result, the appearance quality of the slide fastener 1 and the appearance quality of the clothes in the state where the left and right element rows 15 are meshed can be improved, and the slide fastener 1 and the clothes having a good appearance can be provided.

Further, in the present embodiment, after moving the slider 20 to the sliding limit position, by releasing a pull tab (not shown) to end the sliding operation, the stop claw portion (not shown) of the slider 20 enters the element guide path 28. At the same time, the stop claw portion can be inserted into and accommodated in the above-mentioned claw accommodating portion 47 of the second stop portion 40. As a result, the stop mechanism of the slider 20 can be activated to stably hold the slider 20 at the sliding limit position.

At this time, in the element guide path 28 of the slider 20 held at the sliding limit position, not only the first stop portion 30 and the second stop portion 40 but also the fasteners arranged on the frontmost side in the left and right element rows 15 At least a part of the element 14 (hereinafter, the fastener element 14 is referred to as the first element 14a) is inserted. In this case, it is preferable that 50% or more of the first element 14a, particularly the entire first element 14a, is inserted and accommodated in the element guide path 28. As a result, the meshed state of the left and right element rows 15 can be stably maintained.

Further, in order to accommodate the first element 14a in the element guide path 28 of the slider 20 as described above, the distance between the first stop portion 30 and the first element 14a in the length direction is reduced. Further, thereby, the distance between the second stop portion 40 and the fastener element 14 adjacent to the second stop portion 40 in the length direction can be reduced. As a result, the postures of the first stop portion 30 and the second stop portion 40 can be made difficult to tilt. That is, the first base upper surface 33a and the first base lower surface 33b of the first stop portion 30 and the second base upper surface 43a and the second base lower surface 43b of the second stop portion 40 are parallel to the upper surface and the lower surface of the fastener element 14. It can be easily held (or substantially parallel). As a result, when the first stop portion 30 and the second stop portion 40 enter the element guide path 28 from the shoulder opening of the slider 20, they are prevented from being caught by the upper wing plate 22 and the lower wing plate 23 of the slider 20. The slider 20 can be smoothly slid to the sliding limit position.

Further, in the present embodiment, in the state where the slider 20 is held at the sliding limit position, the protruding portion 34 of the first stop portion 30 is a virtual center line in the width direction of the slider body 21 as shown in FIG. It extends to the right side (second stop 40 side) of 5, and is arranged so as to overlap the second base 43 of the second stop 40 in the thickness direction. In this case, the facing edge portion 34c of the protruding portion 34 is formed so as to extend linearly from the facing edge portion of the first base portion 33 in a plan view, and is formed in the length direction (or the core cord portion 13b). It is arranged in a slanted manner.

At the same time, the second base portion 43 extends to the left side (first stop portion 30 side) of the virtual center line 5 in the width direction of the slider body 21. In this case, the facing edge portion of the second base portion 43 is arranged so as to be inclined with respect to the length direction (or the core cord portion 13b) in a plan view, and is arranged on the facing edge portion of the first base portion 33. It extends in the direction of intersection.

Next, in the slide fastener 1 of the present embodiment, the slider 20 held at the sliding limit position as shown in FIGS. 2 and 3 is directed to the rear (separation direction) for separating the left and right element rows 15. The case of sliding is described.

In the state where the slider 20 is held at the sliding limit position, as described above, the protruding portion 34 of the first stop portion 30 and the second base portion 43 of the second stop portion 40 are on the virtual center line 5. The facing edge portion 34c of the protruding portion 34 and the facing edge portion of the second base portion 43 are arranged so as to be inclined with respect to the length direction.

By sliding the slider 20 backward from the sliding limit position held in such a state, first, the connecting pillar 24 of the slider body 21 faces the first base portion 33 in a plan view. The edge portion and the facing edge portion of the second base portion 43 come into contact with each other from the front side. Further, when the slider 20 continuously moves backward, the protruding portion 34 of the first stop portion 30 and the second base portion 43 of the second stop portion 40 are arranged in the above-mentioned relationship. , The connecting pillar 24 of the slider body 21 can easily press the first stop portion 30 and the second stop portion 40 toward the outside in the width direction, thereby pressing the first stop portion 30 and the second stop portion 40. It can be smoothly separated to the left and right and smoothly guided to the left and right shoulder openings of the slider body 21. As a result, the resistance generated at the start of the sliding operation of the slider 20 can be suppressed to a small value, so that the operability of the slider 20 can be improved.

Further, in the present embodiment, the first stop portion 30 is provided with the first recessed portion 35 and the second stop portion 40 is provided with the second recessed portion 45, so that the sliding limit is as described above. A gap 6 that facilitates attracting the pillar rear end portion 24d of the connecting pillar 24 between the pillar rear end portion 24d of the connecting pillar 24 of the slider 20 held at the position and the first stopping portion 30 and the second stopping portion 40. Is provided.

As a result, at the start of the sliding operation of the slider 20, the pillar rear end portion 24d of the connecting pillar 24 is likely to move rearward by entering the gap 6, so that, for example, the pillar rear end portion 24d of the connecting pillar 24 is the first. Compared to the case where the sliding operation is started from the state where the 1st stop portion and the 2nd stop portion are in contact with each other, the resistance generated in the slider 20 at the start of the sliding operation is reduced, and the slider 20 is operated with a lighter force.
