[0043] 50a end DETAILED DESCRIPTION

[0044] Hereinafter, embodiments of the present invention will be described based on the drawings. Figure 6 The zipper 10 and slider 20 of the first embodiment of the present invention are shown. The zipper 10 includes: a pair of left and right zipper tapes 12; and a pair of chain element rows 16, which include a plurality of zipper chain elements 14 arranged facing each other at edge portions 12a of the zipper tapes 12 on the facing sides along the length direction of the zipper tapes 12.

[0045] A strip-shaped covering layer 18 made of polyurethane or the like is provided on the surface 12b of one side of the pair of left and right zipper tapes 12. The covering layer 18 is strip-shaped and is installed along the length direction of the zipper tape 12. The edge portions 18a on the sides facing each other are roughly consistent with the edge portions 12a of the zipper tape 12, covering the chain element row 16. Here, the width of the covering layer 18 is the same as that of the zipper tape 12. In addition, the covering layer 18 is not provided on the back surface 12c of the zipper tape 12 opposite to the surface 12b. In addition, Figure 6 (a) is a front view of the zipper 10 observed from the surface 12b of the zipper tape 12, and (b) is a rear view of the zipper 10 observed from the back 12c of the zipper tape 12. In the following description, the length direction of the zipper tape 12 is set as the X direction, the width direction of the zipper tape 12 intersecting the X direction is set as the Y direction, and the direction orthogonal to the X direction and the Y direction is set as the Z direction. The slider 20 to be described later installed on the zipper tape 12 is also the same. In addition, the X direction is also called the length direction, the Y direction is called the left-right direction, and the Z direction is called the thickness direction.

[0046] The zipper slider 20 is slidably mounted on the fastener tooth row 16 of the zipper tape 12 so as to engage or disengage the pair of fastener tooth rows 16 by the pair of fastener tooth rows. The slider 20 is provided with: a slider body 22, which is mounted on the fastener tooth row 16 and slides along the X direction; a pull tab 24, which operates the sliding of the slider body 22; and a stop claw body 26, which stops or releases the sliding by the falling and rising operation of the pull tab 24.

[0047] Figure 2 to Figure 4 The slider body 22 is shown, and the slider body 22 includes: an upper wing plate 28 and a lower wing plate 30, which are arranged across the thickness of the zipper tape 12 and the cover layer 18; and a connecting column 32, which connects the upper wing plate 28 and the lower wing plate 30, and is located between a pair of chain element rows 16. The upper wing plate 28 is a plate parallel to the XY plane, and has a semicircular shape that is slightly longer in the X direction and one end edge 28a in the X direction protrudes in the X direction, and the end edge 28b on the opposite side is a straight line along the Y direction. A pair of side edges 28c intersecting the end edges 28a and 28b are straight lines along the X direction, and the portion close to the end edge 28b is formed by a curve that is recessed toward the center of the upper wing plate 28. In a conventional slider body, an upper flange is provided on the curved portion of the upper wing 28 so as to protrude in a direction perpendicular to the upper wing 28 . However, in this embodiment, no upper flange is provided because the back surface of the upper wing 28 is in close contact with the surface of the cover layer 18 .

[0048] The lower wing plate 30 has the same shape and size as the upper wing plate 28, and is in a semicircular shape with one end edge 30a slightly longer in the X direction protruding in the X direction, and the end edge 30b on the opposite side is a straight line along the Y direction. A pair of side edges 30c intersecting the end edges 30a and 30b are straight lines along the X direction, and a portion close to the end edge 30b is formed by a curve recessed toward the center of the lower wing plate 30, and a lower flange portion 36 is provided in the portion of the curve so as to protrude in a direction orthogonal to the lower wing plate 30. The lower flange portion 36 protrudes with a slight gap between the upper wing plate 28, and the interval between the upper wing plate 28 and the lower flange portion 36 is a width that allows the fastener tape 12 and the cover layer 18 to slide in contact.

[0049] The connecting post 32 is in the shape of a rod having a central axis in the Z direction. One end of the connecting post 32 in the Z direction is connected to a position spaced apart from the end edge 28a on the end edge 28b side near the end edge 28a of the upper wing plate 28, and the other end is connected to a position spaced apart from the end edge 30a on the end edge 30b side near the end edge 30a of the lower wing plate 30. The end edges 28a and 30a of the upper wing plate 28 and the lower wing plate 30 protrude in the X direction compared with the connecting post 32. A Y-shaped element guide path 38 is arranged between the upper wing plate 28 and the lower wing plate 30, and the element guide path 38 connects the space arranged on both sides of the connecting post 32 of the end edges 28a and 30a, that is, the shoulder opening 35, and the space arranged at the end edges 28b and 30b, that is, the rear opening 37.

[0050] like Figure 3 As shown, the cross-sectional shape of the connecting column 32 intersecting the Z direction is formed so that the width becomes narrower as it approaches the end edge 28a, 30a. The detailed shape of the connecting column 32 is described below. The connecting column 32 is provided with: a front end face 32a, which is located on the side of the end edge 28a, 30a and is parallel to the YZ plane; and a pair of side faces 32b, which are parallel to the XZ plane. The length of the front end face 32a in the Y direction is shorter than the interval between the pair of side faces 32b, and the corner portion where the front end face 32a and the side face 32b are connected is an inclined surface 32c, which is obtained by chamfering the corner portion surrounded by the front end face 32a and the side face 32b. The angle at which the pair of inclined surfaces 32c intersect toward the front end face 32a is formed into an acute angle. The rear end face 32d on the opposite side of the front end face 32a is in the shape of a semi-cylinder protruding toward the end edge 28b, 30b.

[0051] A pull-tab holding portion 40 is provided on the surface 28d of the upper wing plate 28 on the opposite side of the chain element guide path 38 to hold one end of the pull-tab 24 in a rotatable manner. The pull-tab holding portion 40 is provided in a pair in a left-right separated manner, and each pull-tab holding portion 40 is formed by two protrusions. An insertion groove 42 for accommodating the stop claw body 26 is provided between the pair of pull-tab holding portions 40 separated in the left and right directions. The insertion groove 42 is a rectangular shape elongated in the X direction, and is formed by cutting off a portion of the upper wing plate 28 and the connecting column 32 from the surface 28d of the upper wing plate 28 at a position where the upper wing plate 28 overlaps with the connecting column 32 at a predetermined depth. A claw hole 46 is provided at the bottom portion of the insertion groove 42 on the side of the end edge portion 28b close to the rear opening 37, and the claw hole 46 is penetrated in a manner that allows the claw portion formed on the stop claw body 26 to be inserted. The claw hole 46 is a rectangular shape that is slightly longer in the Y direction than in the X direction, is located at a position closer to the rear opening 37 than the connecting column 32, and is formed so as to penetrate the upper wing plate 28. In addition, a recessed portion 42a for inserting the end of the stop claw body 26 is provided at the bottom portion of the end edge portion 28a side of the insertion groove 42 close to the shoulder opening 35. The recessed portion 42a of the insertion groove 42 is a rectangular shape that is slightly longer in the Y direction than in the X direction, and is formed by cutting a portion of the upper wing plate 28 and the connecting column 32 deeper from the surface 28d of the upper wing plate 28. The connecting column 32 is shaped so as to form the recessed portion 42a of the insertion groove 42. A clamping portion 44 is provided around the end edge portion 28a side of the insertion groove 42 close to the shoulder opening 35, and the clamping portion 44 clamps and fixes the end of the stop claw body 26 on the opposite side of the claw portion.

[0052] The pull tab 24 has a plate-shaped pull tab body that is long in one direction, an opening portion for accommodating a portion of the stop pawl body 26 is provided near one end of the pull tab body, and the end of the pull tab body adjacent to the opening portion is a connecting rod rotatably held by the pull tab holding portion 40. A cam portion is integrally provided on the connecting rod.

[0053] The stop claw body 26 is a metal plate body that is long in one direction and has elasticity, and is provided with a claw portion at one end in the length direction. A hook portion that is embedded in the recessed portion 42a of the insertion groove 42 is provided at the end opposite to the claw portion, and a cover portion that covers the cam portion of the pull tab 24 is provided between the claw portion and the hook portion.

[0054] Next, the assembly method of the slider 20 is described. First, the connecting rod of the pull tab 24 is pressed against a pair of left and right pull tab holding parts 40. Thus, the pull tab 24 is rotatably held on the upper wing plate 28 with the connecting rod as the center. Next, the claw portion is inserted into the claw hole 46, the hook portion is inserted into the recess 42a, and the cover portion covers the cam portion of the pull tab 24, thereby inserting the stop claw body 26 into the insertion groove 42. Then, the hook portion of the stop claw body 26 is pressed and fixed by the pressing part 44, thereby completing the assembly of the slider 20.

[0055] The stop pawl 26 is actuated by the falling and raising operation of the pull tab 24, so that the slider 20 is stopped or released relative to the element row 16. First, when the pull tab 24 is fallen toward the rear opening 37, the cam portion of the connecting rod formed on the pull tab 24 is oriented in a direction parallel to the surface 28d of the upper wing plate 28, and does not interfere with the cover portion of the stop pawl 26, and the pawl portion of the stop pawl 26 protrudes into the element guide path 38 through the pawl hole 46. As a result, the pawl portion of the stop pawl 26 engages with the element row 16 of the zipper tape 12 inserted in the element guide path 38, and the stop position of the slider 20 relative to the element row 16 can be maintained.

[0056] When the pull tab 24 is raised in a direction perpendicular to the surface 28d of the upper wing plate 28, the cam portion interferes with the cover portion of the stop pawl body 26, the stop pawl body 26 is lifted, and the pawl portion of the stop pawl body 26 is pulled out of the element guide path 38. Thus, the stop of the slider 20 relative to the element row 16 is released.

[0057] Next, the manufacturing method of the zipper 10 is described. The fastener element 14 is implanted in the edge portion 12a of the zipper tape 12 to form the fastener element row 16, and the cover layer 18 is installed on the surface 12b of the zipper tape 12. The slider 20 is installed on the pair of zipper tapes 12 installed with the cover layer 18 in a manner that the edge portions 12a face each other, as shown in FIG. Figure 6 The left and right zipper tapes 12 are in a closed state as shown in (a) and (b). Then, the ends of the zipper tapes 12 in the slider sliding direction (X direction) are sewn together so that they will not open, and the zipper 10 is completed. In this state, the fastener element row 16 located in the fastener element guide path 38 of the slider 20 is as shown in FIG. Figure 5 As shown in the figure, the side surface 32b, the inclined surface 32c, and the front end surface 32a of the connecting column 32 are brought closer on the shoulder 35 side, so that the left and right pairs of fastener elements 16 are closed. As a result, a space S in the shape of a triangular prism having a substantially triangular cross-section in the XY plane is formed between the end edge 28a of the upper wing plate 28 and the end edge 30a of the lower wing plate 30. The edge 18a of the left and right pair of covering layers 18 is also closed, and the gap S between the left and right edge portions 18a generated at the front end surface 32a of the connecting column 32 becomes smaller. The upper wing plate 28 of the slider 20 contacts the surface of the covering layer 18, and the end edge 28a of the upper wing plate 28 protrudes more than the connecting column 32, and the upper wing plate 28 overlaps with the space S and covers the space S.

[0058] For example Figure 7As shown, the zipper 10 is used by sewing it to the opening edge 50 of the pocket 48 of the installation object such as clothing. The opening edge 50 is an oblong shape that is long in one direction, and the zipper 10 is installed along the length direction of the opening edge 50. The covering layer 18 is located on the surface side of the clothing, and a pair of covering layers 18 and the slider 20 are exposed at the opening edge 50. The shoulder 35 side of the slider 20 faces one end 50a of the opening edge 50. When the slider 20 is located at the end 50a, the zipper 10 is closed, and the edge 18a of the pair of covering layers 18 is closed, thereby maintaining the water blocking function. The slider 20 is stopped by contacting the end 50a of the opening edge 50 through the connecting column 32, but since the end edge 28a of the upper wing plate 28 protrudes more than the connecting column 32, the end 50a beyond the opening edge 50 overlaps with the fabric of the clothing, thereby having a higher water blocking function.

[0059] According to the zipper 10 of the present embodiment, the structure is simple, the water barrier around the slider 20 is high, and the water barrier at the end of the element row 16 is also high. By deeply studying the shapes and positions of the upper wing plate 28, the lower wing plate 30 and the connecting column 32 of the slider 20, the edge portion 18a of the covering layer 18 covering the element row 16 of the left and right pair of zipper tapes 12 is closed around the slider 20 in a manner that reliably covers the element row 16, and the upper wing plate 28 of the slider 20 contacts the edge portion 18a of the closed pair of covering layers 18, and the water barrier function is effectively exerted. The connecting column 32 is a shape that can form a recessed portion 42a of the insertion groove 42, and the stop pawl body 26 can maintain the stop position of the slider 20 relative to the element row 16. Since the slider 20 is stopped at the end 50a of the opening edge portion 50 of the pocket portion 48 by the stopping pawl body 26, the water barrier is not impaired due to the slider 20 accidentally sliding to open the element row 16. The connecting post 32 stops by contacting the end 50a of the opening edge 50, but since the end 28a of the upper wing plate 28 protrudes in the X direction compared with the connecting post 32, the upper wing plate 28 overlaps the fabric of the clothing beyond the end 50a of the opening edge 50, and can have a water-blocking function. By making the connecting post 32 away from the end 28a toward the rear opening 37, it is possible to obtain a high water-blocking function in a compact shape without extending the end 28a. It is not necessary to form a special structure such as a sealing groove in the zipper tape 12, so the manufacturing man-hours are reduced and the cost is also reduced, and a high water-blocking function can be obtained cheaply.

[0060] Next, based on Figure 8 A second embodiment of the present invention is described. In addition, the same reference numerals are given to the same components as those in the above embodiment and the description thereof is omitted. In the zipper 10 of the present embodiment, a slider 52 is slidably mounted on the chain tooth row 16 of the zipper tape 12 so as to engage or separate the pair of chain tooth rows 16 by means of a pair of chain tooth rows.

[0061] The slider 52 has a slider body 54 mounted on the chain element row 16 and sliding along the X direction, and the slider body 54 includes: an upper wing plate 28 and a lower wing plate 30; and a connecting column 32, which connects the upper wing plate 28 and the lower wing plate 30. The lower wing plate 30 is slightly shorter in the X direction than the upper wing plate 28, and one end edge 30a in the X direction is farther away from the rear opening 37 side than the end edge 28a of the upper wing plate 28.

[0062] In the connecting column 32, one end of the connecting column 32 in the Z direction is connected to a position spaced apart from the end edge 28a toward the end edge 28b of the upper wing plate 28, and the other end is substantially aligned with and connected to the end edge 30a of the lower wing plate 30. The end edge 28a of the upper wing plate 28 protrudes in the X direction relative to the connecting column 32, and the end edge 30a of the lower wing plate 30 is aligned with the connecting column 32 in the X direction.

[0063] The slider 52 of this embodiment has the same effects as those of the above-described embodiment. Furthermore, the lower wing plate 30 has a small outer shape, and can be lightweight. The lower wing plate 30 is not in close contact with the cover layer 18, and can be formed into a free shape.

[0064] In addition, the zipper of the utility model is not limited to the above-mentioned embodiments, and the shape or material of the connecting column or the covering layer of the slider may be appropriately selected to have higher water resistance or waterproofness, and the covering layer may not be provided, and the material, shape or function may be appropriately changed. In addition, the shape of the slider body or the pull tab can be freely designed. The pull tab may also be a structure that does not stop at any position of the chain tooth row. The installation object of the zipper may also be any item other than the bag part of the clothing, and the zipper can be used in various items such as bags other than clothing. The shape of the zipper chain teeth may also be shapes other than those described above.
