Hereinafter, embodiments of the present invention will be described with reference to the drawings. The embodiments are not individually independent, and need not be overexplained. Those skilled in the art can appropriately combine the embodiments, and can also grasp the synergistic effect of the combination. In principle, duplicate descriptions between the embodiments are omitted. The reference drawings are mainly intended to explain the invention and are simplified as appropriate.

The “front-rear direction” described in this application is, in principle, grasped based on the moving direction of the front and rear fastener sliders. In short, the “front-rear direction” corresponds to the up-down direction when FIG. 1 is viewed from the front, and it can be seen that the fastener slider can move in the same direction. The “front-rear direction” can be additionally defined in various ways. For example, the front-rear direction coincides with the extending direction of the opposite side edge of the fastener tape, coincides with the extending direction of the core string, coincides with the arrangement direction of the fastener elements, and coincides with the longitudinal direction of the fastener element row. To do. The “left-right direction” basically corresponds to the left-right direction when FIG. 1 is viewed from the front. “Left-right direction” corresponds to the side-by-side direction of a set of fastener tapes, matches the side-by-side direction of each fastener element of a set of fastener tapes, and is for inserting fastener elements on both sides of the connecting pillars of the fastener slider. This coincides with the horizontal direction of the openings. The “vertical direction” is a direction orthogonal to the “front / rear direction” and the “left / right direction”, and the upper and lower wing plates of the fastener slider and the upper and lower surfaces of various parts are named based on this. . “Thickness direction” corresponds to “vertical direction”. The “thickness direction” is typically a direction perpendicular to the upper and lower surfaces of the front stop and the fastener element, and coincides with the upper and lower arrangement directions of the upper and lower wing plates of the fastener slider.

It will be understood by those skilled in the art that the term indicating each direction can be defined in various forms, and may be defined in other ways in light of the description below.

FIG. 17 is a schematic diagram showing a state in which the right fastener element of the slide fastener moves in the fastener slider.

As shown in FIG. 1, the slide fastener 100 includes a set of fastener stringers 50. In short, the slide fastener 100 includes a left fastener stringer 50m and a right fastener stringer 50n. It should be noted that “first” may be called instead of “left” and “second” may be called instead of “right”, and this is the same for other components.

Each fastener stringer 50 includes a configuration in which a large number of fastener elements 60 are fixed to a core string 54 on the opposite side edge 52 of the fastener tape 51 by injection molding at regular intervals. Furthermore, each fastener stringer 50 includes a configuration in which a front stopper 70 is provided at the upper end of a fastener element row 68 that is an array of a plurality of fastener elements 60, and the front stopper 70 is formed by injection molding on the core string 54. It is stuck. Preferably, the front stop portion 70 is a resin molding portion molded by a molding method typified by injection molding, and is typically configured in a block shape, and this also applies to the fastener element 60. .

Note that the fastener element 60 is not limited to an individual block-shaped resin molded portion of injection molding, and may be a coil element. In the case of a coil element, it will be sewn along the opposing side edge 52 of the fastener tape 51 with a sewing thread.

The left-side fastener stringer 50m is long in the “front-rear direction” coinciding with the vertical direction of the front view of FIG. 1 and includes left-side fastener tape 51m having a predetermined width on the left and right. The left fastener tape 51m is a flexible base material that includes an upper surface 151f and a lower surface 151r as a set of main surfaces 151. The left fastener tape 51m is formed by weaving or knitting synthetic resin yarn, but is not necessarily limited to this, and in some cases, a resin layer for ensuring waterproofness is applied to the upper surface.

The left side fastener element 60m is fixed to the opposite side edge 52m of the left side fastener tape 51m by injection molding at regular intervals. In this example, the left side core of the left side fastener tape 51m is enormous in the sectional view of the opposite side edge 52m. The left fastener element 60m is fixed to the string 54m. The left core string 54m is not an essential component, but by providing the left core string 54m, sufficient attachment strength of the left fastener element 60m to the left fastener tape 51m can be secured.

A left front stop 70m is provided adjacent to the front end of the fastener element row 68m in which the left fastener elements 60m are arranged at regular intervals in the front-rear direction. The left front stop 70m is fixed to the left core 54m by injection molding. At the rear end of the fastener element row 68m, a butterfly stick 101m, which is a component of the back stop 101, is provided, and the butterfly stick 101m is fixed to the left core string 54m by injection molding. In the present embodiment, the left front stop 70m is made of resin instead of metal and has a certain degree of elasticity. Thereby, the operation described later with reference to FIGS. 12 and 13 can be suitably secured.

The above description for the left fastener stringer 50m applies to the right fastener stringer 50n in the same manner. However, the left fastener tape 51m is read as the right fastener tape 51n, the left fastener element 60m is read as the right fastener element 60n, the opposite side edge 52m is read as the opposite side edge 52n, and the left core cord 54m is read as the right core cord 54n. The left fastener element row 68m is read as the right fastener element row 68n, the left front stop portion 70m is read as the right front stop portion 70n, and the butterfly stick 101m is read as the box rod 101n1. As is clear from this replacement, the code indicating the left element includes “m”, and the code indicating the right element includes “n”.

As shown in FIG. 1, when the left fastener stringer 50m and the right fastener stringer 50n are arranged side by side in the same longitudinal direction, the opposing side edge 52m of the left fastener tape 51m becomes the opposing side edge 52n of the right fastener tape 51n. opposite. From such a viewpoint, of the four side edges of each fastener tape 51, the side edge facing the other fastener tape 51 is referred to as “opposing side edge”. The opposing side edge is not necessarily a side edge along the longitudinal direction of the fastener tape, and may be a side edge along the short side direction of the fastener tape.

The right side fastener stringer 50n is provided with a box part 101n2 connected to a box bar 101n1. It is well understood by those skilled in the art that the rear stop portion 101 is configured by the box rod 101n1, the box portion 101n2, and the above-mentioned butterfly rod 101m, and detailed description thereof will be omitted. Note that the back stop portion 101 may be of a type in which the set of fastener stringers 50 is “unopenable / closable” at the lower end position. The back stop portion 101 is not limited to resin and may be made of metal.

The fastener slider 80 is attached to the right fastener stringer 50n in this example. The fastener slider 80 is positioned at the rear end of the right fastener element row 68n, the butterfly stick 101m of the left fastener stringer 50m is inserted into the continuous space between the fastener slider 80 and the box portion 101n2, and the fastener slider 80 is slid forward. Thereby, the left and right fastener stringers 50 separated from each other can be united, that is, the slide fastener 100 can be closed.

The specific configuration of the fastener slider 80 is arbitrary. The configuration of the fastener slider 80 can be understood from, for example, the disclosure of FIGS. 1, 2, 14, and 15. The fastener slider 80 according to this example is a “free slider” that does not have a claw portion that can be locked to the fastener element. By employing the free slider, the fastener slider 80 can be more freely moved, and the operation described later with reference to FIGS. 12 and 13 can be preferably ensured. Needless to say, the fastener slider 80 may have a claw portion.

Hereinafter, the configuration of the fastener slider 80 will be specifically described. The fastener slider 80 is inserted through the left fastener element row 68m including the left fastener element 60m and the right fastener element row 68n including the right fastener element 60n, and the left fastener element row by the sliding movement of the fastener slider 80 in the front-rear direction. The left fastener element 60m and the right fastener element 60n are engaged and disengaged between 68m and the right fastener element row 68n.

As shown in FIGS. 1, 2, 14, and 15, the fastener slider 80 has an upper wing plate 81, a lower wing plate 82 that faces and is parallel to the upper wing plate 81, an upper wing plate 81, and a lower wing plate. A connecting column 83 for connecting the plate 82 on the front end 80F side, a left upper flange portion 85m1 connected to the left edge of the upper blade 81, a left lower flange portion 85m2 connected to the left edge of the lower blade 82, and the upper blade 81 The right upper flange portion 85n1 connected to the right edge, the right lower flange portion 85n2 connected to the right edge of the lower blade 82, the pull attachment portion 88 provided on the upper surface of the upper blade 81, and the pull attachment portion 88 are attached. Including a pull handle 189. The left upper flange portion 85m1 and the left lower flange portion 85m2 are collectively referred to as “left flange portion 85m”, and the right upper flange portion 85n1 and right lower flange portion 85n2 are collectively referred to as “right flange portion 85n”. The left flange portion 85m and the right flange portion 85n are collectively referred to as a “flange portion 85”.

The fastener slider 80 has a front end 80F and a rear end 80R according to the moving direction. Assuming that the fastener slider 80 is moved upward as described with reference to FIG. 1, the front end 80 F of the fastener slider 80 is on the side where the left and right fastener elements 60 in the unengaged state enter the fastener slider 80. is there. The rear side 80F of the fastener slider 80 is the side from which the left and right fastener elements 60 that have passed through the fastener slider 80 and are engaged are brought out.

If it is assumed that the fastener slider 80 is moved in the rearward direction, the rear end 80R of the fastener slider 80 is the side where the engaged right and left fastener elements 60 enter the fastener slider 80. The front end 80 F of the fastener slider 80 is a side from which the left and right fastener elements 60 that have passed through the fastener slider 80 and have become unengaged come out.

The fastener slider 80 has a mirror image symmetry relationship with respect to a plane in which the configuration on the upper wing plate 81 side and the configuration on the lower wing plate 82 side intersect perpendicularly to the connecting column 83. Accordingly, the passage width W84m of the fastener element passage 84m between the connection column 83 and the left lower flange portion 85m2 and the passage width W84m of the fastener element passage 84m between the connection column 83 and the left upper flange portion 85m1 are equal or change equally. It can be said that. Further, the passage widths W84m and W84n are equal, and these may be collectively referred to as “passage width W84”.

The interval between the left flange portion 85m and the right flange portion 85n gradually decreases from the front end 80F side to the rear end 80R side of the fastener slider 80, and then converges to a certain width. In short, the interval between the left flange portion 85m and the right flange portion 85n has a maximum interval W80F on the front end 80F side of the fastener slider 80 and a minimum interval W80R on the rear end 80R side of the fastener slider 80.

When the interval W _p1-p2 of the front stop 70 and the passage width W84 of the fastener element passage 84 satisfy the interval W _p1-p2 > W84, the first force is applied between the connecting column 83 and the flange portion 85. It is possible to push the front stop 70 with a large second force, that is, to “press-fit”, and to enter the “locked state”. A position where the flange portion 85 does not collide with the claw portion 79 may be set to the “locked state”. When the “locked state” is set to the “unlocked state”, the fastener slider 80 moves away from the claw portion 79.

Can be made appropriate. As a result, the fastener slider 80 can be lowered by the operation on the fastener tape 51 without the operation of the human hand on the fastener slider 80 itself. The direction in which the

fastener tape

51m or 51n is pulled is not particularly limited, and may be a front-rear direction, a left-right direction, a vertical direction, or any vector determined from the sum of these directions.

The fastener slider 80 may be lowered downward only by pulling the left fastener tape 51m in the direction of the arrow LD51m. The fastener slider 80 may be lowered downward only by pulling the right fastener tape 51n in the direction of the arrow RD51n. The directions indicated by the arrows LD51m and RD51n are parallel to the main surface 151 of the fastener tape 51 and orthogonal to the opposing side edge 52 of the fastener tape 51.
