Description

Slide fastener

The present invention relates to a slide fastener including a pair of fastener stringers and a stopper that joins the pair of fastener stringers at one end in the longitudinal direction of the pair of fastener stringers.

As an example of the slide fastener described above, a pair of fastener stringers in which a plurality of elements are fixed in two rows along opposite side edge portions of a pair of parallel tapes, and both ends joined at one end in the longitudinal direction of the pair of tapes. In order to do this, there is one provided with a stopper that extends in the opposite direction of the tape (Patent Document 1). In this element, the shape of the part located on one side in the thickness direction of the tape and the part located on the other side are made the same.

As another element, there is an element in which the shape of the portion located on one side in the thickness direction of the tape is different from the shape of the portion located on the other side to improve the appearance (Patent Document 2). More specifically, this element includes a meshing portion that meshes with an opposing element at a portion located on one side in the thickness direction of the tape, and a tape with respect to the meshing portion of the opposing element at a portion located on the other side. A portion that overlaps in the thickness direction is provided.

JP 2001-192530 A Japanese Patent No. 5492981

Since the element meshes with the opposing element, the fixing position in the longitudinal direction of the tape is shifted between one tape and the other tape. Therefore, even among the multiple elements fixed to each tape, the element fixed to one tape is the closest to the stopper, and the element fixed to one tape is fixed to the other tape. Element is second closest to the stop.

In addition, since the stopper extends in the opposite direction of the pair of tapes, the gap between the element closest to the second and the stopper is much larger than the gap between the element closest to the first and the stopper. The appearance in the vicinity of the tool is adversely affected.

Also, since the fastener joins a pair of tapes, it is desirable that the attachment strength of the fastener to the tape is high.

The present invention was created in view of the above circumstances, and its purpose is to improve the attachment strength of a fastener that joins a pair of fastener stringers and to improve the appearance in the vicinity of the fastener. .

The slide fastener of the present invention includes a pair of fastener stringers and a stopper that joins both at one end in the longitudinal direction of the pair of fastener stringers. The pair of fastener stringers includes a pair of tapes and a plurality of elements fixed along respective opposing side edges of the pair of tapes. The element includes a first element portion that is located on one side in the thickness direction of the tape and cannot mesh with the opposing element, and a second element portion that is located on the other side in the thickness direction of the tape and meshes with the opposing element. The second element portion includes a second base fixed to the tape, and a meshing portion that projects from the second base toward the opposing tape and meshes with the opposing element. The first element portion is a first base portion fixed to the tape, a first base portion that protrudes from the first base portion toward the opposing tape, and a part of the first element portion overlaps the meshing portion of the opposing element in the thickness direction of the tape. And a protrusion. The stopper includes a stopper body that joins a pair of tapes and extends in a direction in which the pair of tapes face each other, and a stopper that protrudes in the longitudinal direction of the tape from the stopper body with respect to an element that is the second closest to the stopper body. A tool piece. The fastener piece includes a first piece portion located on the first element portion side in the tape thickness direction and a second piece portion located on the second element portion side in the tape thickness direction.

The first and second piece portions may or may not overlap with the meshing portion of the second element portion of the element closest to the fastener body as viewed from the thickness direction of the tape. In order to improve the appearance of the slide fastener and the stability of the stopper in the thickness direction of the tape, it is desirable to do the following.
That is, the first piece overlaps and the second piece is separated from the meshing portion of the second element portion of the element closest to the fastener main body as viewed from the thickness direction of the tape.

In addition, regarding the longitudinal direction and the thickness direction of the tape, it does not matter whether the stopper is in contact with the first and second closest elements, or whether it is integral. In order to improve the stability of the stopper with respect to the thickness direction and to ensure the flexibility of the slide fastener in the thickness direction, it is desirable to do the following.
That is, with respect to the longitudinal direction of the tape, the fastener main body is separated from the first closest element, the fastener piece is separated from the second closest element, and the first piece portion with respect to the tape thickness direction. Is in contact with the meshing portion of the element closest to the first.

Further, with respect to the longitudinal direction of the tape, the maximum dimension L of the stopper piece, the minimum distance S1 between the first closest element and the stopper body, and the minimum distance S2 between the second closest element and the stopper body. The relationship is not limited, but it is desirable to improve the appearance of the slide fastener in the vicinity of the stopper as follows.
That is, S1 <L <S2.

In addition, the relationship between the maximum dimension W2 of the stopper piece and the maximum dimension W1 of the first element portion in the direction in which the pair of tapes face each other does not matter. To improve the appearance of the slide fastener in the vicinity of the stopper, It is desirable to do as follows.
That is, W2 ≦ W1.

In addition to the pair of fastener stringers and fasteners, the slide fastener has a slider that moves along the opposing side edges of the pair of fastener stringers. It is desirable to do as follows.
The slide fastener includes a slider in addition to a pair of fastener stringers and a fastener. The slider includes a pair of blades opposed to each other in the thickness direction of the tape and a connecting column that connects the pair of blades between the elements. The pair of vanes is to allow the fasteners to be accommodated in the internal space.

According to the slide fastener of the present invention, since the stopper includes the stopper main body and the stopper piece, the second fastener from the stopper main body compared to the conventional stopper (the stopper constituted only by the stopper main body). The gap between the element close to the stopper and the stopper is narrowed by the amount of the stopper piece, and the appearance of the slide fastener in the vicinity of the stopper is improved. In addition, according to the slide fastener of the present invention, the mounting area of the fastener with respect to the tape is increased by the amount of the stopper piece as compared with the conventional stopper (the stopper constituted only by the stopper main body). However, since the tape is sandwiched between the first and second pieces from the thickness direction, the attachment strength of the fastener to the tape is improved.

In addition, according to the slider in which the first piece is overlapped with the meshing portion of the second element portion of the element closest to the stopper main body as viewed from the thickness direction of the tape, and the second piece is separated, Compared to the slider in which the first piece does not overlap the meshing portion, the appearance of the slide fastener can be improved and the stability of the fastener in the thickness direction of the tape can be improved in the vicinity of the fastener.

Further, with respect to the longitudinal direction of the tape, the fastener main body is separated from the element closest to the first, the fastener piece is separated from the second closest element, and the first piece is disposed with respect to the thickness direction of the tape. If it is a slide fastener that is in contact with the meshing part of the element closest to the second, the stability of the fastener in the thickness direction of the tape while ensuring the flexibility in the thickness direction of the slide fastener in the vicinity of the fastener Can be improved.

Further, with respect to the longitudinal direction of the tape, the maximum dimension L of the stopper piece, the minimum distance S1 between the first closest element and the stopper body, and the minimum distance S2 between the second closest element and the stopper body. According to the slide fastener with S1 <L <S2, the gap between the first closest element and the fastener body is narrow compared to the slide fastener with S1> L. The appearance of the slide fastener is improved.

Further, according to the slide fastener in which the relationship between the maximum dimension W2 of the stopper piece and the maximum dimension W1 of the first element portion is set to W2 ≦ W1 with respect to the opposing direction of the pair of tapes, for example, In comparison, since the stopper piece does not protrude in the direction in which the pair of tapes oppose each other than the element, the appearance of the slide fastener can be improved.

In addition to a pair of fastener stringers and fasteners, if the slide fastener has a slider and can accommodate the stopper in the internal space of the pair of blades of the slider, the connecting column of the slider collides with the fastener. Therefore, it is possible to improve the sense of unity between the slider and the stopper and to improve the appearance of the slide fastener.

As shown in FIG. 2 with respect to the left-right direction, the relationship between the maximum dimension W2 of the stopper piece 45 and the maximum dimension W1 of the first element portion 22 is W2 ≦ W1.
With this configuration, the slide fastener 1 of the present embodiment has the stopper piece 45 in the left-right direction (2 in FIG. 2) with respect to the vicinity of the stopper 4 as compared with the slide fastener with W2> W1. Since it does not protrude to the left of the left end of the second element 20, the appearance of the slide fastener 1 can be improved.

The relationship between the stopper 4 and the slider 3 is as follows.
As shown in FIG. 6 with respect to the vertical direction, the relationship between the maximum dimension T2 of the stopper piece 45 and the maximum interval T1 between the pair of

blades

32 and 32 is T2 <T1. Further, the slide fastener 1 has a positional relationship between the stopper 4 and the slider 3 in the vertical direction so that the stopper 4 (T2 within the range of T1) is positioned in the pair of

blades

32 and 32. Regarding the left-right direction, the relationship between the maximum width W4 of the stopper 4 and the minimum distance W5 between the left and

right flanges

34, 34 is W5> W4. The slide fastener 1 has a positional relationship between the stopper 4 and the slider 3 in the left-right direction so that the stopper 4 (W4 within the range of W5) is positioned in the left and

right flanges

34, 34.
With this configuration, when the slider 3 is moved backward and the connecting pillar 33 of the slider 3 is caused to collide with the stopper 4, the stopper 4 is accommodated in the internal space of the pair of

blade plates

32 and 32. Therefore, in the state where the slider 3 and the stopper 4 collide, the sense of unity between the slider 3 and the stopper 4 can be improved, and the appearance of the slide fastener 1 can be improved.

The present invention is not limited to the above-described embodiment, and can be changed as appropriate without departing from the spirit of the present invention. For example, the shape of the fastener main body 40 is rectangular in the above-described embodiment, but the present invention is not limited to this, and may be other shapes such as an elliptical shape and a trapezoidal shape.
