Description

Slide fastener with open fitting insert

The present invention relates to a slide fastener with a break-fitting insert provided with a break-fitting insert having a fitting body and a fitting body at each one end of the left and right fastener tapes. The present invention relates to a slide fastener with a separation fitting that can be pivoted with respect to a body to be fitted by two kinds of fitting operations.

Conventionally, as one of slide fasteners with a separation fitting insert, an element formed on one of a pair of left and right fastener stringers is inserted into the other formed on the other fastener stringer. Passing through the road or directly passing through the flange part of the slider and the side part of the inserted body, it is possible for anyone to easily lock the inserted body into the inserted body. There is known a slide fastener with a separable fitting that can be used. The specific configuration of the slide fastener with the opening / closing insert is disclosed in, for example, Japanese Patent Application Laid-Open No. 2008-43568 (Patent Document 1) and International Publication No. 2010/109656 (Patent Document 2).

According to Patent Documents 1 and 2, the fitting body includes a thin plate-like fitting plate portion integrally formed on both front and back surfaces of the one fastener tape, and a tape end side tip portion of the fitting plate portion. And the fitting body is integrally formed on both the front and back surfaces of the other fastener tape, and a slider holding section for holding the slider, and the fitting body is pivoted. It has possible said fitting part. The fitted portion is formed thick on the tape end side of the slider holding portion via a stepped portion, extends from the slider holding portion to the tape end side, and further toward the fitting body side. A curved substantially J-shaped inner surface and a fitting space into which the pivot stop can be fitted from a side portion of the fitting body toward the substantially J-shaped inner surface; and the substantially J-shaped A fitting plate portion fitting groove for rotatably supporting the pivot stop portion is provided on the inner surface of the shape.

The slide fastener with a separation / insertion tool having the above-described configuration is fitted like a conventional side-open type separation / insertion tool described in Japanese Utility Model Publication No. 59-25227 (Patent Document 3). Not only enables a first pivoting operation to be pivoted to the fitting portion by fitting the body from the side of the fitting body, but is similar to a general opening / closing insertion tool having a butterfly pin or the like. Furthermore, it is comprised so that an insertion body can be made to pivot at an insertion part also by the 2nd pivoting operation which inserts an insertion body into a to-be-inserted body via the element guide path of a slider. . Thereby, in the slide fastener with a separation fitting insert disclosed in Patent Documents 1 and 2, the first pivot stop is used when the insert body is pivoted to the fit body in order to close the slide fastener. It is possible to arbitrarily select an operation and the second pivoting operation.

For this reason, when using the slide fastener with the separation fitting insert described in Patent Documents 1 and 2, if the user is not familiar with the operation of the side opening type separation fitting insert, By smoothly performing the second pivoting operation for pivoting the insertion part by inserting it into the body to be inserted through the slide fastener, it is possible to smoothly close the slide fastener without taking time and effort to operate the separation fitting. If you are used to, or have become accustomed to, the operation of the side-open type opening / closing insertion tool, insert the insertion body from the side of the insertion body into the insertion section. By performing the first pivoting operation for pivoting, the slide fastener can be more easily closed.

Further, according to Patent Documents 1 and 2, when the slide fastener is opened, as in the case of the pivoting operation, the user can select any one of two different operations for removing the release fitting. Can be selected arbitrarily. Therefore, the slide fastener with a separation / insertion insert described in these Patent Documents 1 and 2 is a general separation having a slide fastener with a side-open type separation / insertion insert, a butterfly stick, and the like. Compared to a slide fastener with a fitting insert, the ease of use of the opening and closing insertion tool is greatly improved, and it is excellent in convenience and operability, so that it becomes a slide fastener that anyone can easily use.

When closing the left and right fastener stringers, in the first pivoting operation, the pivoting portion of the fitting body is inserted into the fitting portion of the fitting body. Next, after the slider is slid to a position where the slider comes into contact with the stepped portion on the tape end side of the slider holding portion of the inserted body, the pivot stop is fitted into the substantially J-shaped inner surface. By rotating the insert body through the slit toward the insert body around the pivot stop portion, the insert plate portion of the insert body is inserted into the slider through the gap of the flange portion of the slider. At this time, since the to-be-inserted body has a substantially J shape, the pivot stop portion of the insert body is stably pivoted by the fitting plate portion fitting concave groove on the substantially J-shaped inner surface.

The second pivoting operation is performed by sliding the slider to a position where the slider comes into contact with the stepped portion on the tape end side of the slider holding portion of the inserted body, and then inserting the inserted plate portion of the inserted body. Is inserted from the shoulder of the slider, and the pivoting portion of the fitting body is fitted into the fitting portion of the fitting body. Thus, the left and right element rows are positioned so that stable meshing can be performed.

In this way, by inserting (inserting) the slider into the element engagement direction of the slider and the object to be inserted, the slider is slid (pulled up) to engage the left and right element rows to close the slide fastener. .

Therefore, the slide fastener with a separation / insertion tool described in Patent Documents 1 and 2 facilitates the separation / insertion operation of the slide fastener, for example, a product that requires the operation of the slide fastener with one hand, the opening Patent Document 3 discloses a product in which the position of the separation / insertion tool cannot be directly visually recognized and the slide fastener is operated by groping, and further, a product that requires the operation of the slide fastener in an environment where it is difficult to perform detailed work. It can be suitably used more than a slide fastener with a side-open type separation fitting insert.

JP 2008-43568 A International Publication No. 2010/109656 Pamphlet Japanese Utility Model Publication No.59-25227

By the way, the slide fastener with a break-and-insert insert that is mainly applied to clothes and bags described in Patent Documents 1 and 2 seems to be applied to automobile seats and seat covers in recent years. Thus, when the slide fastener is closed, a strong tearing force so as to tear the left and right fastener tape ends on the side of the separation / insertion tool side to the left and right due to the movement of the human body or the like (referred to as reverse tearing force in the present application). Has increased to work. Also, in clothing, reverse tearing force similar to that described above may be exerted due to inadvertent catching or the like. Such reverse tearing force is applied to the leading edge in the tape length direction of the left and right fastener tapes and the front and back surfaces of each fastener tape end, and one side edge of each fastener tape end. It acts directly on one point of each crossing portion between the fitting body and the fitting body extending along.

As a result, there is a risk that the joint between the thin reinforcing piece and the fitting body and the fitting body may be peeled off. This is because when the large reverse tearing force acts on one point of the intersecting portion, the fitting body and the fitting body whose mutual positions are fixed by closing the slide fastener are in a pivoted state, and the fastener tape At the same time, the reinforcing piece joined to the front and back surfaces of the end portion of the fastener tape is strongly pulled in the tearing direction along the leading edge in the tape length direction. That is, the fitting body whose mutual position is immovable and the right and left fastener tape and the reinforcing piece firmly fixed to the fitting body are stretched in the tearing direction along the front edge by the reverse tearing force. Deviation occurs in the joining between the insert body and the insert body, and the reinforcing piece is peeled off from the insert body and the insert body together with the fastener tape, which may lead to breakage of the slide fastener.

The present invention has been made to solve these problems. The purpose of the present invention is to integrally bond the front and back surfaces of the end portion of the fastener tape via reinforcing pieces even if the strong reverse tearing force described above acts. An object of the present invention is to provide a slide fastener with a separable fitting, in which peeling does not occur between the formed fitting body and the fitting body and the reinforcing piece.

The above object has a pair of left and right fastener element rows through which sliders are inserted on opposite side edges of the pair of left and right first and second fastener tapes, which is the main configuration according to the present invention. A fitting body having a film-like reinforcing piece joined and integrated to each end portion of each fastener tape adjacent to the end portion, and fixedly provided along a side edge portion of each reinforcing piece, and the fitting body Is provided with a separation fitting having a fitting body that also functions as a bottom stop of the slider, and the slider is connected to the guide column and the guide column. A blade plate and a lower blade plate, and a flange portion standing on the right and left side edges of the upper blade plate and / or the lower blade plate, and the fitted body includes the fitted body described above. The fitting part that can be pivoted by fitting from the side of the fitting object In the slide fastener with an opening and closing insert, the free ends of the fitting body and the fitting body are beyond the edge of each fastener tape and each reinforcing piece in the tape length direction. It protrudes in the tape length direction, and when the slide fastener is closed, the end edges in the length direction of the first and second fastener tapes and the reinforcing piece and the free ends of the fitting body and the fitting body Two or more continuous straight lines having one or more bent portions at the edge of the intersection of the fastener tape passing at least the intersection of the fitting and the first fastener tape at the intersection with the fixed edge. It is effectively achieved by a slide fastener with a break-off fitting insert, characterized in that it has a notch portion formed in the above.

According to a preferred aspect, it is desirable that the notch is formed in a region including each sewing line for the product to be sewn of the first and second fastener tapes.
Moreover, according to a preferable aspect, the said insertion body is a tape-shaped insertion board part integrally formed in the front and back both surfaces of the said 1st fastener tape, and the tape edge part side front-end | tip part of the said insertion board part. A pivot holding portion formed on the front and back surfaces of the second fastener tape, and the slider holding portion for holding the slider and the fitting body can be pivoted. And the pivoting portion is extended to a thickness on the tape end side of the slider holding portion via a stepped portion, and is further curved toward the fitting body side. A substantially J-shaped inner surface and a fitting space into which the pivoting portion can be fitted from the side portion of the fitting body toward the substantially J-shaped inner surface, and at the same time on the substantially J-shaped inner surface The pivoting portion can be pivotably rotatable. Moreover, the said to-be-inserted body can be made pivotable also by inserting the said insertion body through the element guide path of the said slider.

More preferably, the bent portion has two straight lines, and the straight lines are bent at a right angle or an acute angle. Further, a core string is interposed along the element row of the fastener tape, the pivot stop is formed at an end of the core string, and the core string portion in the formation area of the pivot stop is left. And the length of the core string portion in the tape length direction is the tape length of the second notch portion. It is preferable to set it shorter than the length in the direction.

Further, in the present invention, it is preferable that a fitting plate portion fitting groove capable of fitting the fitting plate portion is formed on a side surface of the slider holding portion facing the fitting plate portion. Moreover, it is preferable that the fitting plate part fitting groove is formed to extend on a part of the substantially J-shaped inner surface of the fitting part.

As with the slide fastener described in Patent Documents 1 and 2, the slide fastener with a separation / insertion tool according to the present invention is fitted into the insertion object by fitting the insertion object from the side of the insertion object. There are two different types, a first pivoting operation for pivoting and a second pivoting operation for inserting the inserted body into the fitted body via the element guide path of the slider and pivoting the fitted body. It is possible to perform a pivoting operation.

In the present invention, as described above, the configuration is characterized by having at least the above-described notch. By including this characteristic configuration, it is possible to effectively reduce the strong reverse tearing force that acts on the intersection between the longitudinal edge of the fastener tape, the fitting body, and the fitting body. As a specific aspect of the notch, one or more bent portions such as a rectangular shape or a step shape, particularly preferably 2 are formed at each edge in the tape length direction of the fastener tape passing through the intersecting portion. There are two or more straight lines, and the straight lines are bent at a right angle or an acute angle, and cut out on two or more straight lines to form a notch. If a notch is formed, even if a strong tearing force toward the outside along each edge in the tape length direction of the fastener tape acts on the sewing product such as a sheet or clothing, the tearing force is Instead of being immediately transmitted to the intersecting portion, the fastener tape is added via a sewing thread on a sewing line with respect to the product to be sewn on the end of the fastener tape.

The reverse tearing force transmitted through the sewing thread at this time is first transmitted to the bent part of the notch, and a part of the reverse tearing force is dispersed in the bent part, and the reverse tearing force after being dispersed Is transmitted to the intersection. When the bent portion has an obtuse angle of, for example, 90 ° or more, the bent portion does not exhibit a buffer function, and the tearing force is immediately transmitted to the intersecting portion, which causes the problems described above. .

As a result of forming the notch as described above, the reverse tearing force transmitted to the intersection is reduced. That is, since the first strong reverse tearing force is distributed and reduced every time one or more bent portions are sequentially passed, the finally reduced reverse tearing force is transmitted to the intersection. Even if a strong reverse tearing force is applied to the end edge of the fastener tape in the longitudinal direction, it does not peel off from the fitting body and the joint between the fitting body and the reinforcing piece, preventing the slide fastener from being damaged. Is done.

Normally, the reverse tear force applied to the sewing product is, as described above, the end of the slide fastener in the tape length direction via the sewing thread on each sewing line for the sewing product of the first and second fastener tapes. Added along the edges. Here, as in the prior art, when the notch in the present invention is not formed at the edge in the longitudinal direction of the fastener tape, the reverse tearing force is concentrated at one point of the intersection along the edge. And will act directly. Thus, as in the present invention, when the notch is formed in the region including the sewing line, the reverse tear force transmitted to the intersecting portion via the sewing thread of the sewing product is the stitch portion in the notch. The seam that actually sews the product to be sewn and the fastener tape that are not cut off is mainly involved. Since the position of the seam where the product to be sewn and the fastener tape is actually sewn is removed from the notch, the reverse tearing force acting through the seam is caused by the bent part of the notch. The reverse tearing force that should be concentrated at one point by the bent portion is reliably dispersed and the magnitude of the reverse tearing force transmitted to the intersecting portion is effectively reduced. .

Also, a core string is attached to the edge in the width direction of the fastener tape. On the other hand, the fitting body and the fitting body molded from a synthetic resin material are molded and integrated so as to encapsulate the surface of the core string via a reinforcing piece. Usually, the thickness of the core string is greater than the thickness of the fastener tape, and the core string bulges linearly on the surface of the fastener tape at the site where the core string is attached. On the other hand, in particular, the fitting plate portion of the fitting body must be able to easily pass through the slit formed in the side portion of the mating object of the other party, so that it is thinner than the slit width and smooth on both the front and back surfaces. Need to be. In order to make the front and back surfaces of the fitting body smooth, the thickness of the fitting plate portion of the portion covering the surface of the core string has to be further reduced, which further weakens. Therefore, as described above, when a strong reverse tearing force is applied to the intersecting portion, the portion covering the surface of the core string of the fitting plate portion is easily broken, and the fitting plate portion and the reinforcing piece And the function as a slide fastener with a separation / insertion tool as a slide fastener may be lost.

In the present invention, as described above, the pivot stop portion is formed at the end portion of the core cord, and the core string portion in the formation region of the pivot stop portion is left, and the element row end portion side. Since the second cutout portion is partially cut out, the second cutout portion is filled with the molding material of the fitting plate portion, and the portion is the fitting plate portion. It is thicker than other parts, coupled with the function of the above-mentioned notch, and the strength of the fitting plate part is further increased in the part affected by the reverse tearing force, so that problems such as tearing do not occur, and open fitting As a slide fastener with an insert, it can be used stably over a long period of time.

FIG.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the present invention is not limited to the embodiments described below, and various modifications can be made as long as it has substantially the same configuration as the present invention and has the same effects. Is possible. For example, in the following examples, the fastener element and the separation / insertion tool have been described for a slide fastener formed by injection molding a synthetic resin, but the present invention is not limited to this, for example, a coil-shaped A slide fastener in which a fastener element or a metal separation / insertion tool is attached to a fastener tape may be used.

FIG. 1 is an overall view in which an intermediate portion of a slide fastener with a separation / fitting insert according to Example 1 of the present invention is omitted, and FIG. 2 is an attachment of the separation / fitting insert of the slide fastener with the separation / fitting insertion tool. It is the perspective view which showed the principal part of the site | part. In the following, in order to explain the present invention more easily, on the basis of the slide fastener 1 with the same opening and closing insert shown in FIG. 1, the slider 30 is moved in the longitudinal direction of the tape so that the slide fastener 1 is closed. The direction of sliding along the upper side of the figure is defined as the front, and the direction of sliding so that the slide fastener 1 is separated (lower of the figure) is defined as the rear. Further, when the slide fastener 1 is viewed from the front, the side on which the fitting body 10 of the separation / insertion tool 5 is formed in the width direction of the fastener tape 2 is the left side, and the fitting body 20 is formed. The side that is on is defined as the right side. Moreover, the direction orthogonal to the front and back surfaces of the fastener tape is defined as the height direction, and the dimension in this direction is represented by the thickness.

As shown in FIG. 1, the slide fastener 1 with a separation / insertion tool according to the first embodiment includes a pair of left and right first and second fastener tapes 2 a and 2 b, and first and second fastener tapes 2 a, The fastener element 3 arranged in the opposite side edge of 2b, the separation fitting 5 provided adjacent to the lower end part of the right and left fastener element row | line | column 4, and the slider 30 are provided. *

The first and second fastener tapes 2a and 2b have a core string 7 that is larger (thick) than the fastener tape along the opposing side edges. A plurality of fastener elements 3 are arranged at regular intervals along the included element mounting edge to constitute a fastener element row 4. Each fastener element 3 includes a body portion fixed to the left and right fastener tapes 2a and 2b, a neck portion extending from the body portion toward the outside of the tape, and a massive engagement head provided at the tip of the neck portion. For example, a synthetic resin material such as polyacetal which has been generally used conventionally can be attached to each fastener tape 2a, 2b by injection molding into a predetermined shape.

The slider 30 can be a generally known slider, such as an upper blade 31a, a lower blade 31b, and left and right edges of the upper blade 31a and the lower blade 31b. The upper and lower flanges 32a and 32b arranged in the orthogonal direction along the upper and lower wing plates 31a and 31b are installed on the upper wing plate 31a. And a puller 34. Therefore, a Y-shaped element guide path that is bifurcated from the rear opening toward the shoulder opening is formed inside the slider 30. In the present invention, the slider 30 may be one in which a flange portion is erected on the left and right end edges of either the upper wing plate 31a or the lower wing plate 31b, for example.

At the lower ends of the fastener tapes 2a and 2b, film-like reinforcing pieces 15 are joined and integrated with the front and back surfaces of the fastener tape, and the reinforcing pieces 15 are formed at the side edges of the fastener tape so as to wrap the core string 7. It is folded and joined to the front side and the back side. Although one reinforcing piece 15 is joined (adhered) to each fastener tape 2a, 2b, two reinforcing pieces can be formed on the front and back sides. Moreover, you may join only to one of the surface or the back surface.

As shown in an exploded view in FIG. 2, the opening / closing insert 5 is continuous with the fastener element row 4 on the reinforcing piece 15 at the rear end of each of the first and second fastener tapes 2a and 2b. The synthetic resin fitting body 10 and the fitting body 20 are provided to face each other.
The fitting body 10 includes a thin rectangular plate-like fitting plate portion 11 integrally formed (fixed) on both front and back surfaces of the lower end portion of the first fastener tape 2a along the opposing side edges of the left and right fastener tapes. , The pivot stop portion 12 formed at the tip end portion of the tape rear end side of the insertion plate portion 11, and the inner side of the tape on the front and back of the insertion plate portion 11 (the surface of the tape more than the fastener tape side edge provided with the fastener element row 4 And the engagement portion 14 formed continuously from the fastener element row 4 at the front end portion of the fitting plate portion 11.

Further, in the first embodiment, as shown in FIG. 3, the first fastener tape 2a in which the insertion body 10 is formed has the center portion of the tape rear end edge joined to the front and back surfaces of the fastener tape. A cutout portion 16 is formed by cutting into a rectangular shape including the film-like reinforcing piece 15. The rear end free end (the side opposite to the fastener element row 4 side) of the insertion plate portion 11 protrudes rearward beyond the rear end edge of the first fastener tape 2a, and the fixing end of the insertion plate portion 11 is fixed. The left side surface of the rear end at the edge and the rear ends of the first fastener tape 2a and the reinforcing piece 15 intersect substantially at right angles to form an intersection A in the present invention (FIG. 7). The fitting plate portion 11 is flat on both the front and back surfaces except for the protruding portion 13, and the thickness in the tape front and back direction is formed smaller than the gap between the upper and lower flanges 32a and 32b of the slider 30. ing.

As shown in FIG. 2, the lower end portion of the fitting plate portion 11 has a pivot stop portion 12, and a cylindrical shaft portion 12 a protrudes from the front and back surfaces of the pivot stop portion 12. The shaft portion 12a has a thickness in the tape front and back direction that is smaller than the distance in the height direction of the element guide path in the slider 30, that is, the distance between the upper blade 31a and the lower blade 31b in the slider 30. It is formed larger than the gap between the gaps provided between the flanges 32a and 32b.

The protruding portion 13 is formed to be thicker than the fitting plate portion 11. By forming such a thick protrusion 13 along the inner edge of the tape, the strength of the fitting 10 can be improved, and the user who operates the separation fitting 5 Therefore, it is easy to grip the fitting.

A core string 7 is attached to each of the opposing side edges of the first and second fastener tapes 2a and 2b. Since the core string 7 is thicker than the fastener tape 2, when the fitting plate portion 11 having a flat surface at the portion where the core string 7 is formed is molded with a synthetic resin, the core string 7 is formed on the core string 7. The thickness of the fitting plate part 11 of a part becomes very thin. Thus, when the thickness of the fitting plate portion 11 is locally reduced, the strength of the thin portion becomes extremely small, and for example, as described later, the slide fastener is torn at the rear end edge of the first fastener tape 2a. When a large force (reverse tearing force) is applied, the first fastener tape 2a and the film-like reinforcing piece 15 joined to the surface of the rear end portion of the fastener tape 2a extend, and at the same time, the insertion plate portion 11 The thin part may break. In order to make such an inconvenience the entire surface of the fitting plate portion is a flat surface, as in Patent Document 1, a recess portion can be provided at the surface position where the core string is arranged in the fitting plate portion.

The inserted body 20 includes a slider holding portion 21 formed on both front and back surfaces of the second fastener tape 2b via reinforcing pieces 15, and a reinforcing portion 25 and a step portion 22 on the rear end of the slider holding portion 21. And is formed in the tape inward of the insertion portion 23 having the substantially J-shaped inner surface 24 and the insertion space 28, and the slider holding portion 21, to the fastener tape 2 of the insertion subject 20. Reinforcing portion 25 for increasing the fixing strength of the plate, and the fitting plate portion fitting formed along the side surface of the slider holding portion 21 facing the fitting plate portion 11 and a part of the substantially J-shaped inner surface 24 A slit 27 that communicates with the recessed groove 26 and the fitted plate portion fitting recessed groove 26 and that can be inserted through the fitted plate portion 11 that penetrates from the outer peripheral surface of the fitted portion 23 to the substantially J-shaped inner surface 24. And have. The groove width of the slit 27 in the tape front and back direction is set larger than the thickness of the fitting plate portion 11 so that the fitting plate portion 11 can be inserted.

The slider holding portion 21 is formed such that its thickness in the tape front and back direction is smaller than the height of the element guide path inside the slider 30 and larger than the gap between the upper and lower flanges 32a and 32b. In addition, the insertion member facing side edge of the slider holding portion 21 is curved so that the intermediate portion slightly bulges toward the insertion member 10. Further, as will be described later, the slider holding portion 21 is inserted into the element guide path of the slider 30 when the slider 30 is slid and brought into contact with the stepped portion 22 (see FIG. 5). Hold.

In the first embodiment, the fitting portion 23 is thicker than the slider holding portion 21 via the step portion 22 and extends outwardly from the slider holding portion 21 beyond the tape rear end, Since it is curved from the tip toward the fitting body 10 side, it has a substantially J shape in front view. In addition, the inserted portion 23 includes an insertion space 28 in which the pivoting portion 12 of the fitting body 10 can be fitted from the side portion of the fitted body 20, and a pivot stop fitted in the insertion space 28. It has a substantially J-shaped inner surface 24 that can be pivotally supported by contacting the portion 12. The curvature radius of the substantially J-shaped inner surface 24 is formed so as to be substantially equal to the radius of the shaft portion 12 a of the fitting body 10.

In addition, according to the present Example 1, like the 1st fastener tape 2a, the reverse tearing which is the most characteristic of this invention is carried out in the center part of the rear-end edge of the 2nd fastener tape 2b to which the to-be-inserted body 20 was attached. A rectangular notch 16 serving as a force reducing means is formed.

The configuration described above is basically not different from the slide fastener with the separation / insertion tool described in Patent Documents 1 and 2 except for the notch portion 16, but in the first embodiment, As described above, the configuration different from the slide fastener with the split-fitting insert of Patent Documents 1 and 2 is the end of the first and second fastener tapes 2a, 2b on the side of the split-fitting insert attaching side. A notch 16 formed of a rectangular or stepped bent part and two or more straight lines, which is a reverse tearing force reducing means in the present invention, is formed at the center of the edge. Here, the notch portion 16 is formed to be recessed in the tape longitudinal direction from the rear end (lower end) of the intersecting portion A of the fastener tape and the reinforcing piece, and from the rear end edge of the intersecting portion A in the left-right direction from A. After continuing to the rear edge in the direction of leaving, the notch 16 is formed.

Furthermore, in the present Example 1, as shown in FIG.4 and FIG.7, it exists in the side edge part of the side by which the core string 7 of the 1st fastener tape 2a was attached, and the fixed area | region of the said insertion body 10 was shown. A second notch is formed by cutting out a portion having a length of approximately 1/12 to 1/5 of the entire region where the fitting body 10 is fixed, leaving the core string end 7a at the rear end in a rectangular shape. A portion 17 is formed. For example, when the length of the fixed area of the fitting body is 20 mm or more, the length of the second notch 17 is about 1.7 to 5.0 mm. When the length of the core string end portion 7a along the core string 7 is L1, and the notch depth before and after the notch portion 16 is (dimension in the tape longitudinal direction) d1, the relationship of L1> d1, that is, The notch depth d1 of the notch portion 16 is set to be smaller than the length L1 along the core string 7 of the core string end 7a. Further, the width dimension (thickness) w in the left-right direction of the core string 7 is set to be smaller than the notch depth (dimension in the left-right direction of the tape) d2 of the second notch portion 17 in the left-right direction. Yes. The shaft portion 12 a of the fitting body 10 is formed at a portion corresponding to the core string end portion 7 a of the core string 7.

Moreover, in the present Example 1, as shown in FIG. 8, the 1st fastener tape shows the formation part of the said notch part 16 formed in the rear-end edge of 1st and 2nd fastener tape 2a, 2b. The intersection position B includes the sewing line 8a of 2a.

In addition, in the to-be-inserted body 20 which is thicker than the insertion board part 11 of the insertion body 10, since the said core cord 7 is completely embed | buried under the inside of the to-be-inserted part 23, it is Even if a reverse tearing force is applied to the second fastener tape 2b to which the body 20 is attached, the fitted body 20 is not torn, and the second fastener tape 2b has the second notch portion. 17 need not be formed.

In the above configuration, first, the closing and opening operation of the slide fastener 1 with the opening and closing insert according to the first embodiment will be briefly described.
In closing the slide fastener 1, as described above, the fitting body 10 of the opening / closing insertion tool 5 is pivoted to the fitting body 20 by fitting it from the side of the fitting body 20. 1 is inserted into the element guide passage from the shoulder opening of the slider 30 abutting on the inserted body 20, and then the fitted body 20 is fitted. A second pivoting operation for pivoting the insertion part is possible.

First, the first pivoting operation will be described. In this first pivoting operation, the pivoting portion 12 of the fitting body 10 is inserted into the fitting space 28 of the fitting portion 23 of the fitting body 20. . Next, after the slider 30 is slid and brought into contact with the stepped portion 22 on the tape end side of the slider holding portion 21 of the inserted body 20, the pivoting portion 12 has a substantially J-shaped inner surface. The fitting body 10 fitted in 24 is rotated through the slit 27 around the pivoting portion 12 toward the fitting body, whereby the fitting plate portion 11 of the fitting body 10 is moved to the slider 30. Is inserted into the slider through the gap between the left upper flange 32a. At this time, since the fitted portion 23 of the fitted body 20 has a substantially J shape, the pivoting portion 12 of the fitted body 10 is fitted into the fitted plate portion fitting recess of the substantially J-shaped inner surface 24. The groove 26 is stably supported.

In the second pivoting operation, the slider 30 is slid to a position where it abuts against the step 22 on the tape end side of the slider holding portion 21 of the inserted body 20, and then the inserted body 10. The fitting plate part 11 is inserted from the shoulder opening of the slider 30, and the locking part 12 is fitted into the fitted part 23 of the fitted body 20. Thus, the left and right element rows 4 and 4 are positioned so that stable meshing can be performed.

After the insertion body 10 is inserted into the slider 30 and the insertion portion 23 of the insertion body 20 in this way, the slider 30 is slid in the element meshing direction (pulled up), whereby the left and right element rows 4 and 4 are moved. The slide fastener 1 is closed by engaging with each other.

In the first embodiment, when the slide fastener 1 in the closed state is released, the slider 30 pulled upward is slid toward the insertion body 20 to abut the step portion 22. . Subsequently, the pivot portion 12 of the fitting body 10 supported by the fitting portion 23 of the fitting body 20 is replaced with the slit 27 and the slider 30 formed at the bending portion side tip 23 a of the fitting body 20. 2 is different in that the gap formed between the upper and lower flanges 32a and 32b is pulled out from the side of the inserted body 20 or pulled out through the element guide path of the slider 30. The left and right fastener stringers can be separated by performing any one of the types of removal operations.

In particular, in the slide fastener 1 according to the first embodiment, when the slider 30 is held by the slider holding portion 21 and is in contact with the stepped portion 22, the left fastener stringer is inclined with respect to the right fastener stringer. The pivoting portion 12 of the fitting body 10 can be easily removed from the fitting space 28 of the fitting body 20. For this reason, when the pivoting portion 12 is removed from the side portion of the fitted body 20, the left and right fastener stringers can be more easily separated as compared with the case where the pivoting portion 12 is removed from the element guide path of the slider 30. it can.

As described above, the slide fastener 1 with the opening and closing insert according to the first embodiment has the first pivoting operation for pivoting the fitting body 10 by fitting the fitting body 10 from the side portion thereof. The insertion body 10 has a structure capable of performing a second pivoting operation that pivots by inserting the insertion body 10 into the insertion body 20 through the element guide path of the slider 30. For this reason, when closing the slide fastener 1, the user can arbitrarily select these two different pivoting operations. Moreover, the slide fastener 1 of the first embodiment makes it easier to close the slide fastener 1 by performing the first pivoting operation as described above compared to the case of performing the second pivotal operation. Can do.

By the way, the slide fastener having the structure as described above has been often applied to ordinary clothes and bags. However, in recent years, for example, an automobile seat or a seat cover is used because of its ease of opening / closing operation. The demand to apply as an open / close device is growing. However, these seats and seat covers try to separate the slide fastener, particularly the opening / closing insert, which serves as a lower stopper thereof, to the left and right not only during traveling of the vehicle but also by movement of the body weight when getting on and off. A powerful force acts. However, since the slide fastener is in a closed state at this time, the element row is in a meshed state, and since the fitting body and the fitted body of the separation / insertion tool are in a pivoting state, the meshing of the element row is released. Further, the separation between the insertion body and the insertion body is not easily performed.

At this time, the strong force acting on the slide fastener is not uniform because it works through the product to be sewn such as a flexible sheet or seat cover, and it is not a simple lateral pulling force. Since the force that tries to separate the fitting body attached to the opposite side edge of the end portion and the fitting body is applied to the left and right fastener tapes via the seat and the seat cover, A force that tries to separate the fitting body and the fitting body at a relatively fixed position to rotate diagonally forward, that is, the reverse tearing force used in this specification is Works. This will be described in detail with reference to FIG. 8. The reverse tearing force described above is transmitted along the respective rear end edges in the length direction of the left and right first and second fastener tapes 2a, 2b and the reinforcing piece 15, It acts on one point of intersection A between each rear end edge and the tape fixing side edge of each free end portion of the fitting body 10 and the fitting body 20.

In the present invention, the strong reverse tearing force that acts in a concentrated manner on the intersection A is distributed in two or more stages along the rear edge of each fastener tape 2a, 2b, whereby the intersection A In consideration of the fact that the reverse tear force actually transmitted to the fastener tapes 2a and 2b can be reduced, the reverse tear force reducing means is disposed on the rear edges of the fastener tapes 2a and 2b. As a means for reducing the reverse tearing force, there is a notch portion 16 that is notched along two or more straight lines having one or more bent portions at the rear end edges of the fastener tapes 2a and 2b. According to the first embodiment, the cutout portion 16 is cut out in a rectangular shape. The shape of the notch is not limited to a rectangular shape, and may be a stepped shape having one bent portion as in Example 2 shown in FIG. The bent portion is not particularly limited as long as the two straight lines bend at different angles, but it is preferable that the two straight lines be bent at a right angle or an acute angle.

In the first embodiment, when the rectangular cutout portion 16 is formed at the rear edge of each fastener tape 2a, 2b, the slide fastener 1 is formed on the sewing product 8 such as a seat or a seat cover shown in FIG. Is sewn along the sewing line 8a. The sewing line 8a crosses the notch 16, and the slide fastener 1 is sewn to the product 8 by sewing thread. Therefore, the reverse tearing force applied to the sewing product 8 is transmitted along the rear end edge of the fastener tape 2 via the sewing thread, and then reaches the intersection A with the separation fitting 5.

Therefore, when the sewing line 8a and the notch 16 intersect, and there is a seam inside the notch 16, the reverse tearing force is directly transmitted to the fastener tape 2 from the seam. Instead, it is transmitted along the rear edge of the fastener tape 2 through the seam adjacent to the notch 16. Also in this case, the reverse tearing force is transmitted along the rear end edge of the fastener tape 2, and the bent portion 16a of the cutout portion 16 near the separation fitting tool 5 is present in the middle thereof. In 16a, it deform | transforms into a linear form with the reverse tear force transmitted from the said seam part.

At this time, a part of the reverse tearing force is used as a deformation force for pulling and deforming the bent straight line portion linearly, and the remaining reverse tearing force is directly transmitted to the split fitting 5. That is, the reverse tearing force transmitted to the fastener tape 2 via the sewing thread is dispersed at the bent straight line portion, and a part thereof is transmitted to the separation fitting 5 so that the reverse tearing force at the time of initial occurrence is transmitted. Is reduced and transmitted to the separation / fitting insert 5, the amount of extension of the fastener tape 2 and the reinforcing piece 15 in the pulling direction is reduced, and the amount of deviation between the reinforcing piece 15 and the separation / fitting insertion tool 5 is also reduced. It will be less and there will be no peeling between them. Here, by increasing / decreasing the number of the bent portions 16a, the number of dispersions can also be increased / decreased, and the reverse tearing force transmitted to the separation / insertion tool 5 can be adjusted.

In the first embodiment, as shown in FIG. 3, in addition to the notch portion 16, a second notch is formed at the element row forming side edge portion of the first fastener tape 2 a in the formation region of the fitting body 10. A notch portion 17 is formed. This is because the fitting plate portion 11 of the fitting body 10 is thin on the element row forming side edge portion, and the core is attached along the element row forming side edge portion of the fitting plate portion 11. Since the thickness of the cord 7 is larger than the thickness of the fastener tapes 2 a and 2 b, the resin thickness of the fitting plate portion 11 that encloses the concentric string 7 is extremely thinner than the other fitting plate portions 11. As a result, the strength of the portion of the fitting plate portion 11 that encloses the core string 7 is weakened compared to other portions, and when the reverse tearing force acts, the weakened portion easily breaks easily. As a result, the function as the separation / insertion tool cannot be exhibited. Therefore, in the first embodiment, as described above, the second notch portion 17 is formed in the fitting body 10.

Moreover, in the present Example 1, the three through-holes 9 are provided in the three corresponding | compatible parts of the 1st fastener tape 2a which straddles the boundary of the said insertion board part 11 and the said protrusion part 13 of the insertion body 10. FIG. And a single through hole 9 is formed on the second fastener tape 2b corresponding to the portion of the inserted body 20 that crosses the boundary between the substantially J-shaped inserted portion 23 and the reinforcing portion 25. The second fastener tape 2b is formed with two through holes 9 on a straight line passing through the through holes 9 and corresponding to the reinforcing portion 25. In the first embodiment, the second notch portion 17 is formed only in the first fastener tape 2a, and the slider holding portion 21 of the inserted body 20 and the substantially J-shaped inserted portion 23. Since there is sufficient thickness, it is possible to secure a strength sufficient to withstand use, and therefore the second notch portion 17 is not provided. However, the 2nd notch part 17 can also be provided.

In the first embodiment, as described above, the second notch portion 17 is provided in the portion where the reverse tearing force is most strongly applied to the first fastener tape 2a, thereby being fitted into the second fastener tape 2b. In forming and integrating the body 10, the resin of the fitting body 10 is completely filled in the second cutout portion 17, and the second cutout portion 17 is formed between the second fastener tape 2 b and the reinforcing piece 15. Since the joint portion is eliminated, the strength of the second notch portion 17 increases, and even if the reverse tearing force is applied, the same portion is not torn. Further, by forming the through holes 9 in the first and second fastener tapes 2a and 2b as described above, a part of the material of the reinforcing piece 15 passes through the through holes 9 and the first and second fastener tapes 2a and 2b. Reinforcing pieces 15 to be joined to the front and back surfaces are connected, and the joining strength between the fastener tapes 2a, 2b and the reinforcing piece 15 is improved.

Next, a slide fastener with a separation / insertion tool according to Embodiment 2 of the present invention will be described with reference to the drawings. Here, FIG. 9 is a front view showing the main part of the opening / closing insert mounting portion of the slide fastener with opening / closing insert according to the second embodiment. FIG. 10 is a front view showing the main part of the separation / insertion tool mounting portion when the slide fastener is sewn to the sewing product. In the following description, the same reference numerals and names as those in the first embodiment are used for members and components that are substantially the same as those in the first embodiment. Therefore, detailed description of these members will be omitted.

A substantially L-shaped groove 127 is formed along the inner surfaces of the vertical portion 123a and the horizontal portion 123b. The groove 127a of the vertical portion 123a is a fitting plate portion fitting groove 26 formed in the slider holding portion 21 of the fitting body 20 into which the fitting plate portion 11 of the fitting body 10 of the first embodiment is fitted. In the same manner as described above, the groove is connected to the fitting groove 127 c of the fitting plate portion of the slider holding portion 121.

(2) The pivot stop portion 112 on the tape end side of the flange insertion body 110 does not have the shaft portion 12a as in the first embodiment, and is formed integrally with the end portion of the insertion plate portion 111, and is one end from the tape end. Is formed by a small plate piece having an engaging surface around it. The front and back surfaces of the fitting part 111 and the pivot part 112 made of the small plate piece have the same continuous surface, and the thickness of the fitting groove part 127 and the fitting groove 127c is substantially L-shaped. It is set smaller than the groove width (groove thickness dimension). Of the substantially L-shaped groove 127 of the inserted body 120, the groove depth of the groove 127b of the horizontal portion 123b is formed deeper than the groove depth of the groove 127a of the vertical portion 123a. It is made into the shape which loosely fits the pivot stop part 112 which consists of the said small piece of the said insertion body 110, and the concave groove 127b of this horizontal part 123b supports the said pivot stop part 112 so that rotation is possible. The insertion space is configured.

(3) The notch shape of the notch 116, which is a reverse tearing force reducing means formed on the edge of each of the first and second fastener tapes 102a, 102b on the side where the cleavage / insertion fitting 105 is disposed, Instead of the rectangular shape as in the first embodiment, the tape edge has a bent portion and a straight line that rises in a stepped manner through one step on the side opposite to the separation fitting 105. Yes.

Even in the slide fastener 101 with the break-and-fit insert according to the second embodiment having the structure (1), (2), and (3) different from the first embodiment, the slide with the same break-and-insert insert When the fastener 101 is closed by the first pivoting operation, the slider 30 (see FIGS. 5 and 6) is operated to close the stepped portion 22 of the inserted body 120 as in the first embodiment. Slide along the element row 4 until it abuts. Next, after fitting the pivoting portion 112 of the fitting body 110 into the concave groove 127b formed in the horizontal portion 123b of the substantially L-shaped fitting portion 123, the fitting body 110 is centered on the pivoting portion 112. As shown in FIG. At this time, the fitting plate portion 111 of the fitting body 110 is moved to the upper and lower flanges on the left side of the slider 30 so that the meshing portion 14 provided at the end of the fitting body 110 on the element row side exceeds the shoulder opening of the slider 30. It is made to pass through the gap between 32a and 32b. Here, the slider 30 is slid to the upper stopper side (not shown), the left and right element rows 4 and 4 are engaged, and the slide fastener is closed.

Also in the second embodiment, the slide fastener can be closed by the second pivoting operation similar to that of a normal slide fastener with a separation / insertion tool. That is, first, the slider 30 is slid along the element row 4 until it contacts the stepped portion 22 of the inserted body 120. Next, the fitting body 110 is inserted from the shoulder opening of the slider 30 (see FIGS. 5 and 6) and is fitted into the groove 127b formed in the horizontal portion 123b of the fitting body 120 through the element guide path. At this time, the fitting plate portion 111 of the fitting body 110 is inserted into the gap between the upper and lower flange portions 32 a and 32 b on the left side of the slider 30. By only the second pivoting operation, the fitting body 110 can be supported so as to be rotatable relative to the fitting body 120 around the pivoting portion 112 of the fitting body 110.

In spite of such a simple structure, in addition to the fact that the fitting body 110 can be easily pivoted to the fitting body 120 by the first and second types of pivoting operations, Even in Example 2, similarly to the above-described Example 1, the notch 116 serving as the reverse tearing force reducing means is formed, so that the tape end of the slide fastener 101 on the side of the separation / insertion tool attachment side is strong. When a reverse tearing force is applied, no peeling phenomenon occurs between the reinforcing piece 15 and the fitting 110. In the first embodiment, the four-step bent portion including the notch starting end and the terminal end is provided. However, in the second embodiment, the notch 116 has a two-step bent portion including the notch starting end. Only. Thus, in Example 2, when a strong reverse tearing force in the tearing direction is applied to the tape end portion, the force is transmitted to a stepped bent portion in the middle through the notch starting end. At this time, the strong reverse tearing force is dispersed at the notch starting end and each stepped bent portion in the middle, and the reduced reverse tearing force is applied to the intersection C between the final fitting 110 and the tape edge. As described above, the peeling phenomenon between the reinforcing piece 15 and the fitting body 110 is prevented.
