Detailed Description
Hereinafter, embodiments of the fastener coupling according to the present invention will be described with reference to the drawings. Fig. 1 to 6 show a first embodiment of the present invention, and a fastener for slide fastener 10 of the present embodiment is detachably attached to a slider 18, wherein the slider 18 is attached to a fastener body 16 having fastener elements 14 provided on a fastener tape 12 so as to face each other.
The slider 18 will be explained here. The slider 18 includes a body 20 for opening and closing the fastener elements 14 of the fastener body 16, a tab 22 for operating the body 20, and a tab attachment portion 24 for holding the tab 22 on the upper surface of the body 20. The pull-tab attaching portion 24 is a member extending in the sliding direction of the slider 18, and is bent in a zigzag shape of 1246720 a protruding from the upper wing plate 20a of the slider 18 with its tip positioned on the upper wing plate 20a of the main body 20. An attachment hole 23 is formed in one end of the tab 22, and the tab 22 is attached to the body 20 by inserting the tab attachment portion 24 into the attachment hole 23. The pull tab 22 is pivotally supported so as to be rotatable in a direction parallel to the sliding direction of the slider 18, i.e., the longitudinal direction of the fastener body 16.
The body 20 is provided with a pair of upper wing plate 20a and lower wing plate 20b attached so as to sandwich the fastener element 14 of the fastener body 16 from above and below, and a connecting column 26 is provided between the upper wing plate 20a and the lower wing plate 20b. The space between the upper wing plate 20a and the lower wing plate 20b is a guide passage 28 through which the fastener element 14 passes. The guide path 28 is provided with a coupling post 26 on the side separating the fastener elements 14, the fastener elements 14 are separated in two directions, and a space is formed together with the upper wing plate 20a and the lower wing plate 20b by a pair of guide edge portions 30 protruding from the upper wing plate 20a toward the lower wing plate 20b on the side where the fastener elements 14 are engaged, and the guide path 28 is formed in a Y-shape. The side of the body 20 from which the fastener elements 14 are separated is referred to as a front side, and the side from which the fastener elements 14 are engaged is referred to as a rear side. The guide edge portion 30 is a wall that is substantially perpendicular to the upper blade 20a and the lower blade 20b, and a tip portion facing the lower blade 20b faces the lower blade 20b so as to have a slit slightly wider than the thickness of the fastener tape 12 of the fastener main body 16. The guide edge portion 30 is located outside the side surfaces of the rows of the pair of fastener elements 14 that are away from each other, and guides the pair of fastener elements 14 to be engaged with each other by sliding the main body 20.
Next, the fastener 10 for a slide fastener will be explained. The fastener 10 is formed by integrally and continuously molding each part with a synthetic resin such as a thermoplastic resin having an appropriate elasticity. The fastener 10 has a deformed rectangular plate-like upper portion 32, and has side edge portions 32a, 32b positioned on a pair of parallel straight lines, and the side edge portion 32a is slightly longer than the side edge portion 32 b. The pair of side edges 32c and 32d connecting both ends of the side edges 32a and 32b are slightly longer than the side edge 32a, and the distance therebetween is wider on the side of the side edge 32a and becomes narrower as it approaches the side edge 32 b. The thickness of the upper portion 32 is slightly thicker on the side of the side edge portion 32a, and gradually becomes thinner as it approaches the side edge portion 32 b. The lower surface 32e of the upper portion 32 in the thickness direction is formed as a flat surface without irregularities. The opposite upper side surface 32g is formed of an inclined surface, a curved surface, or a flat surface.
A through hole 34 into which the body 20 of the slider 18 is fitted is formed in the center of the upper portion 32 so as to pass through in the thickness direction. In the shape of the through hole 34, a portion close to the side edge portion 32a is a short linear portion 34a parallel to the side edge portion 32a, and a portion close to the opposite side edge portion 32b is a long linear portion 34b parallel to the side edge portion 32 b. The pair of side edge portions 34c and 34d connecting the end portions of the linear portion 34a and the end portions of the linear portion 34b to each other have a curved shape with the center portion bulging in a direction away from each other, and a portion continuous with the linear portion 34b is a straight line intersecting the linear portion 34b at right angles. This is along the shape of the body 20 of the slider 18 fitted into the through hole 34, and the rear side of the body 20 where the fastener elements 14 are engaged coincides with the linear portion 34b.
The lower surface 32e is provided with an inclined surface 35 having a thickness gradually decreasing toward the side edge 32b in a portion near the side edge 32 b. In addition, the portion of the straight portion 34b of the through hole 34 on the side of the edge portion 32b is cut away so as to have a thickness of about half of the lower side surface 32e, thereby forming a recessed portion 37. The concave portion 37 has a surface 37a parallel to the lower surface 32 e.
A quadrangular prism-shaped coupling portion 36 extending downward from the lower surface 32e at a substantially right angle is provided on the lower surface 32e of the upper portion 32 at a portion adjacent to the side edge portion 32a, and the coupling portion 36 has a rectangular cross-sectional shape that is wide in a direction parallel to the side edge portion 32 a. A plate-shaped lower portion 38 substantially parallel to the lower surface 32e is continuously provided at a lower end of the connection portion 36. The lower portion 38 is a semicircular plate body having a constant thickness, the portion continuous with the coupling portion 36 is the center of the circumference of the semicircle, and the portion opposite to the coupling portion 36 is a diametrically linear side edge portion 38a. The portion of the upper surface 38b facing the lower surface 32e of the upper portion 32 near the skirt portion 38a is provided with an inclined surface 40 whose thickness gradually decreases as it approaches the skirt portion 38a. The upper side surface 38b is provided with a projection 42 slightly projecting from the upper side surface 38 b. The projection 42 is formed in an oblong shape extending in a direction perpendicular to the side edge 38a and parallel to the upper side surface 38b, and 1 projection 42 is provided on each side of the center of the upper side surface 38 b.
An engaging projection 44, which is an engaging portion for detachably coupling the pair of fastener fasteners 10, is provided on a front surface 32f of the upper portion 32 along the thickness direction at the side edge portion 32 a. The engaging convex portion 44 has a cylindrical shape protruding in a direction substantially perpendicular to the front surface 32f, i.e., in the moving direction of the slider 18, and a large diameter portion 44a having a large diameter is provided at a front end portion located at the front end with respect to the middle of the protruding direction. The engaging projection 44 is located near an end of the front surface 32f near the side edge 32 d.
In the vicinity of the end portion of the front surface 32f close to the side edge portion 32c on the opposite side to the side edge portion 32d, an engagement groove portion 46 is provided, which is an engaged portion into which the engagement convex portion 44 of the other fastener coupling 10 is inserted and engaged. The engaging groove portion 46 is formed by being recessed inside the upper portion 32, and is a through hole formed in the front surface 32f and having a semicircular shape, and a thin slit extends from the through hole to the lower side surface 32e at a substantially right angle and communicates with the lower side surface 32 e. The semicircular through hole is slightly smaller than the large diameter portion 44a of the engaging convex portion 44.
Next, a method of using the fastener 10 for a slide fastener will be described. The fastener coupling 10 is attached to the slider 18 of the fastener body 16 by elastic deformation. As shown in fig. 5, the fastener coupling 10 is held on the front side of the slider 18 where the fastener elements 14 are not engaged, the side edge 38a of the lower portion 38 is overlapped with the lower blade 20b of the slider 18 while abutting the inclined surface 40, the upper portion 32 is abutted with the tab attaching portion 24 of the upper blade 20a, and the space between the upper portion 32 and the lower portion 38 is enlarged by being elastically deformed by being strongly pressed. When the pull-tab attaching portion 24 is positioned in the through hole 34 of the upper portion 32, the elastic deformation is restored, and as shown in fig. 6, the attachment of the fastener coupling 10 to the slider 18 is completed. The straight portion 34b of the through hole 34 of the fastener coupling 10 abuts on the rear side of the tab attaching portion 24 of the slider 18 where the fastener elements 14 are engaged. The linear portion 34a of the through hole 34 and the connection portion 36 communicating with the linear portion 34a are in contact with the front side of the tab attaching portion 24. This prevents the fastener coupling 10 from moving in the front-rear direction with respect to the slider 18. The side edges 34c, 34d of the through hole 34 face the side edges in the left-right direction intersecting the front-rear direction of the upper blade 20a, and the fastener coupling 10 does not move in the left-right direction. The rear end of the upper blade 20a is received in a recess 37 of the upper portion 32 continuous with the through hole 34, the upper surface 37a of the recess 37 faces the upper blade 20a, and the lower portion 38 faces the lower blade 20b, so that the fastener coupling 10 does not move in the vertical direction.
The pull-tab 22 is attached to the pull-tab attachment portion 24 of the slider 18, and the pull-tab 22 is pulled outward from the through hole 34 of the fastener coupling 10, whereby the slider 18 can be moved while holding the pull-tab 22. The pull-tab 22 does not become an obstacle when the fastener coupling 10 is attached to the slider 18, through the through hole 34 of the fastener coupling 10.
As shown in fig. 1, two or a pair of sliders 18 are attached to the fastener body 16, and the pair of sliders 18 are opposed to each other on the front side where the fastener elements 14 are not engaged. The fastener coupling 10 is attached to each slider 18, and used in a state where the front surfaces 32f face each other. Thus, the engaging convex portion 44 of one fastener coupling 10 faces the engaging groove portion 46 of the other fastener coupling 10.
When the pair of sliders 18 are brought close to each other and the front surfaces 32f of the fastener coupling 10 are brought into contact with each other in use, the engaging convex portions 44 are inserted into the engaging groove portions 46, and the engaging groove portions 46 are expanded by elastically deforming the peripheries of the engaging groove portions 46, so that the large diameter portions 44a of the engaging convex portions 44 can pass therethrough. After the large diameter portion 44a passes through and is accommodated in the recess 50, the large diameter portion 44a is elastically deformed and restored, and is engaged with and cannot be pulled out. Thereby, as shown in fig. 2, the pair of sliders 18 are coupled to each other. Even if one slider 18 is moved along the fastener body 16, the other slider 18 is moved in conjunction with each other, and therefore, the engagement of the fastener elements 14 is not largely opened. When the engagement of the fastener elements 14 is released, the pair of sliders 18 are pulled apart with a predetermined or more strength, and the periphery of the engagement groove portion 46 is elastically deformed to pass the large diameter portion 44a of the engagement convex portion 44 and be pulled out, thereby releasing the coupling. Then, when the pair of sliders 18 are moved in the direction away from each other, an opening portion is formed between the pair of sliders 18, in which the engagement of the fastener element 14 is released. When the fastener 10 is not required, the pull-tab attaching portion 24 can be easily removed by pulling up the side edge portion 32b of the upper portion 32 and elastically deforming the same to pass through the through hole 34.
According to the fastener for a slide fastener 10 of the present embodiment, the engagement convex portion 44 can be engaged with the engagement groove portion 46 by holding the pull tab 22 of the slider 18 and bringing the pair of sliders 18 close to each other, and the engagement between the engagement convex portion 44 and the engagement groove portion 46 can be released by holding the pull tab 22 and pulling the pair of sliders 18 apart from each other, and the operation of engagement and release of engagement is easy. Further, the slider 18 can be attached to the fastener body 16 by elastic deformation with a simple structure. In addition, the slider can be easily detached when not needed, and can be added to the existing slider 18, and the shape of the slider 18 does not need to be specially made into a special shape, so that the cost is not high. The pair of sliders 18 attached to the fastener body 16 can be coupled to each other by a simple operation of abutting the pair of sliders 18, and the pair of sliders 18 can be operated in cooperation to serve as an anti-theft measure. When the fastener body 16 is opened, the coupling can be released simply by pulling apart the pair of sliders 18 by force, and the slider 18 after the coupling is released can be moved in a direction away from each other, thereby opening the fastener body 16. Inclined surfaces 35, 40 are formed on the upper portion 32 and the lower portion 38, and when the inclined surfaces 35, 40 abut against the upper blade 20a and the lower blade 20b of the body 20 of the slider 18, they are biased in the direction of elastic deformation, and the fastener stringer 10 can be easily elastically deformed and attached to the slider 18. In particular, when the inclined surface 40 is initially brought into contact with the lower wing plate 20b of the slider 18, elastic deformation is caused, and the attachment is easy. The attachment to the slider 18 and the coupling between the pair of sliders 18 are both performed by elastic deformation, and a jig, a screw structure, or the like is not required, which is relatively simple. The user can detach the fastener coupling 10 freely according to the situation, and can perform repair of the fastener body 16 conveniently. The fastener coupling 10 is a single component, and the component management is also easy. The upper portion 32 is attached to the upper blade 20a of the slider 18 so as to surround the entire periphery thereof, and the lower portion 38 is attached to the lower blade 20b so as to overlap therewith, so that the attachment area with the slider 18 is wide, and the attachment strength is high. Since the lower portion 38 is provided with the projection 42, the projection 42 can be brought into contact with the lower blade 20b at high pressure.
Next, a second embodiment of the present invention will be described with reference to fig. 7 to 9. Here, the same components as those of the above embodiment are denoted by the same reference numerals, and description thereof is omitted. The fastener coupling 60 of the present embodiment is integrally molded from a synthetic resin having suitable elasticity. The fastener 60 is provided such that the upper portion 32 and the lower portion 38 are coupled by the coupling portion 36.
A through hole 34 into which the slider 18 is fitted is formed in the center of the upper portion 32 so as to penetrate in the thickness direction. A grip cover portion 62 is formed on the upper side 32g of the upper portion 32 so as to cover the through hole 34. The handle cover portion 62 is formed in an arch shape protruding in the thickness direction from the upper side surface 32g of the upper portion 32, and is integrally formed with the upper portion 32. The shape of the upper surface 62a of the grip cover portion 62 that continues to the upper side surface 32g and protrudes upward is such that the distal end portion is a ridge line extending in the front-rear direction at substantially right angles to the side edge portion 32a, and the periphery of the ridge line is an inclined surface facing the upper side surface 32 g. Thus, the shape of the upper surface 62a of the grip cover 62 is a triangular shape having an acute angle as viewed from the side edge portion 32a or the side edge portion 32b as shown in fig. 8 (a) and (d), and a trapezoidal shape as viewed from the side edge portion 32d as shown in fig. 8 (c). This is a shape that can be easily pinched by hand from both sides of the side edge portion 32c and the side edge portion 32 d. As shown in fig. 9, a lower surface 62b of the handle cover portion 62 continuous with the lower surface 32e is a plane parallel to the lower surface 32e, and closes the through hole 34. A slider recess 62c is formed in the center of the lower surface 62b, and houses the tab attaching portion 24 of the slider 18 to which the fastener coupling 60 is attached. The slider recess 62c has a size sufficient to accommodate the tab attaching portion 24.
Next, a method of using the fastener 60 for a fastener will be described. The fastener coupling 60 is attached to the slider 18 of the fastener body 16 by elastic deformation, as in the first embodiment. However, in the present embodiment, the pull tab 22 is not provided on the slider 18. The pull-tab attachment portion 24 is located inside the handle-shaped cover portion 62. Two or a pair of sliders 18 are attached to the fastener body 16, and the fastener coupling 60 is attached to each slider 18, and used in a state where the front surfaces 32f face each other, as in the first embodiment. Thus, when the pair of sliders 18 are brought close and the front surfaces 32f are brought into contact with each other, the engaging convex portion 44 is inserted into the engaging groove portion 46, and the pair of sliders 18 are coupled to each other. When the pair of sliders 18 is pulled apart by a predetermined force or more, the connection is released. When the fastener 10 is not required, the side edge 32b of the upper portion 32 is pulled up to be elastically deformed, and the fastener is easily removed.
The fastener 60 of the present embodiment has the same effects as those of the above embodiments. The handle-shaped cover portion 62 can be easily moved while being held without attaching the pull tab 22 to the slider 18. The outward appearance is simple and clean and tidy.
Next, a third embodiment of the present invention will be described with reference to fig. 10. Here, the same components as those of the above embodiment are denoted by the same reference numerals, and description thereof is omitted. The fastener coupling 64 of the present embodiment is integrally molded from a synthetic resin having suitable elasticity. The fastener coupling 64 is provided such that the upper portion 32 and the lower portion 38 are coupled by the coupling portion 36.
A through hole 34 into which the slider 18 is fitted is formed in the center of the upper portion 32 so as to pass through the upper portion in the thickness direction. A flat cover portion 66 is provided on the upper side 32g of the upper portion 32 so as to cover the through hole 34. The flat cover portion 66 is an arch protruding in the thickness direction from the upper side surface 32g of the upper portion 32, and is integrally formed with the upper side surface 32 g. The shape of the upper surface 66a of the flat cover portion 66, which continues to the upper surface 32g and protrudes upward, is a flat hemispherical shape, and the shape viewed from the side edge portion 32a or the side edge portion 32b of the upper portion 32 is formed by a circular arc of half circumference or less as shown in fig. 10 (a) and (d), and the shape viewed from the side edge portion 32d is formed by a circular arc of half circumference or less that is slightly longer than the circular arc as shown in fig. 10 (c). The lower surface of the flat cover portion 66 continuous with the lower side surface 32e is a plane parallel to the lower side surface 32e, and closes the through hole 34. A slider recess is formed in the center of the lower surface, and receives the tab attachment portion 24 of the slider 18 to which the fastener coupling 64 is attached.
The fastener coupling 64 is used in the same manner as in the second embodiment. However, when the slider 18 is moved, the flat cover portion 66 of the fastener coupling 64 is moved while being pressed from above.
The operation and effect of the fastener coupling 64 are also the same as those of the second embodiment. However, since the flat cover portion 66 is flat, it does not scratch other members, and the appearance is neat.
Next, a fourth embodiment of the present invention will be described with reference to fig. 11 and 12. Here, the same components as those of the above embodiment are denoted by the same reference numerals, and description thereof is omitted. The fastener 65 of the present embodiment is also integrally molded from a synthetic resin such as a thermoplastic resin having suitable elasticity. The fastener 65 is provided such that the upper portion 32 and the lower portion 38 are coupled by the coupling portion 36.
The shape of the lower portion 38 is such that the side edge 38c continuous with the connecting portion 36 is parallel to and substantially the same length as the side edge 32a of the upper portion 32. A front surface 38f located on the same imaginary plane as the front surface 32f of the upper portion 32 is continuously provided on the side edge portion 38c of the lower portion 38. In the fastener 65 of the present embodiment, the engaging convex portion 44 and the engaging groove portion 46 are not provided on the front surface 32f of the upper portion 32 but are provided on the front surface 38f of the lower portion 38, unlike the first embodiment. The engaging convex portion 44 of the fastener coupling 65 is located in the vicinity of the end portion of the front surface 38f of the lower portion 38 close to the side edge portion 32 d. An engagement groove portion 46 into which the engagement convex portion 44 is inserted and engaged is provided near an end portion of the front surface 32f close to the side edge portion 32c on the opposite side to the side edge portion 32 d.
Next, a method of using the fastener 65 for a fastener will be described. The fastener coupling 65 is attached to the slider 18 of the fastener body 16 by elastic deformation, as in the first embodiment. Two or a pair of sliders 18 are attached to the fastener body 16, a fastener coupling 65 is attached to each slider 18, and the front surfaces 38f face each other, as in the first embodiment. When the pair of sliders 18 are brought close and the front surfaces 38f are brought into contact with each other, the engaging convex portion 44 is inserted into the engaging groove portion 46, and the pair of sliders 18 are coupled to each other. When the pair of sliders 18 is pulled apart by a predetermined force or more, the connection is released. When the fastener 65 is not required, the side edge 32b of the upper portion 32 is pulled up to be elastically deformed, and the removal is simplified.
The fastener 65 of the present embodiment has the same effects as those of the above embodiments. Since the engaging convex portion 44 is formed on the lower portion 38 located on the back side of the fastener main body 16, the engaging convex portion 44 is hidden when viewed from the front side of the fastener main body 16 in a state where the pair of fastener coupling elements 65 are not coupled, and therefore, the appearance is simple and neat.
Next, a fifth embodiment of the present invention will be described with reference to fig. 13 to 15. Here, the same components as those of the above embodiment are denoted by the same reference numerals, and description thereof is omitted. The fastener coupling 68 of the present embodiment is composed of two members, i.e., a male member 70 and a female member 72, which are detachably coupled to each other.
Fig. 14 shows a male member 70 having an upper portion 32 formed with a through hole 34, a lower portion 38 provided via a coupling portion 36, and a pair of male leg portions 74 provided as engaging portions on a front surface 32f of the upper portion 32. The male leg portions 74 are provided at both ends of the front surface 32f intersecting the side edge portions 32c and 32d, and protrude by a predetermined length in a direction away from the front surface 32 f. The male-shaped leg portion 74 is a plate body that is thin in the thickness direction of the upper portion 32, has a narrow width at the base end and a wide width at the tip end located at the tip end in the middle of the protruding direction, and has tip ends that are slightly bent so as to approach each other. The thickness of the male leg 74 is substantially the same as the thickness of the upper part 32 from the base end to a halfway position in the protruding direction, and a thin part 76, which is a flat surface cut out from both the upper and lower directions, is formed at the halfway position in the protruding direction, so as to be thinner, and an engaging projection 78 protruding from the thin part 76 in a vertically thicker manner is provided at a portion closer to the tip than the thin part 76. The snap tabs 78 are slightly thinner than the upper portion 32. The engaging projections 78 are finely continuous at the mutually facing side edge portions of the pair of male-portion leg portions 74, and a spring portion 80 that connects the pair of male-portion leg portions 74 is provided at a midway portion in the longitudinal direction of the mutually facing side edge portions. The spring portion 80 is a rod bent and bent, and connects the pair of male leg portions 74 to be elastically deformable, and when the pair of male leg portions 74 are elastically deformed so as to approach each other, it is biased in a direction to move away from each other.
Fig. 15 shows a female member 72 having an upper portion 32 formed with a through hole 34 and a lower portion 38 provided via a coupling portion 36. A thin plate-like upper surface portion 82 continuous in the same plane as the upper surface portion 32g is provided to protrude outward at an end portion of the front surface 32f continuous with the upper surface portion 32g, a lower surface portion 84 continuous in the same plane as the lower surface portion 32e is provided at an end portion continuous with the lower surface portion 32e, and a space between the upper surface portion 82 and the lower surface portion 84 is a housing space 86 into which the male portion leg portion 74 of the male member 70 is inserted and engaged. The end portions 82a, 84a of the upper surface portion 82 and the lower surface portion 84 on the opposite side from the front surface 32f serve as insertion ports into which the male leg portions 74 are inserted. Engaged portions 88, with which the engaging projections 78 of the male-shaped portion leg portions 74 serving as engaging portions are engaged, are provided so as to project from the back surfaces of the pair of side edge portions 82b, 84b that continue from both sides of the end portions 82a, 84a and reach the front surface 32 f. The engaged portion 88 is shaped to elastically deform the pair of male portion leg portions 74 inserted from the end portions 82a, 84a in a direction to approach each other as the insertion depth increases. When the male leg 74 is deeply inserted and passes through the engaged portion 88, the elastic deformation of the male leg 74 is restored, and the engaging projection 78 of the male leg 74 engages with the front surface 32f side portion of the engaged portion 88, so that the male leg 74 is not pulled out. The engaged portions 88 provided on the upper surface portion 82 and the lower surface portion 84 and facing each other are spaced apart from each other to form a slit 90 through which the thin portion 76 of the male leg portion 74 passes. A thin connecting wall 92 is provided between the upper surface 82 and the lower surface 84 to connect the upper surface 82 and the lower surface 84 to each other. Since the connecting wall 92 is thin, it does not hinder engagement with the male leg 74.
Next, a method of using the fastener 68 for a fastener will be described. The male member 70 and the female member 72 of the fastener coupling 68 are attached to the slider 18 of the fastener body 16 by elastic deformation. The mounting method is the same as the first embodiment. The pull tab 22 is attached to the tab attaching portion 24 of the slider 18, and the pull tab 22 is pulled out from the through hole 34 of the male member 70 or the female member 72, thereby enabling operation.
As shown in fig. 13, two or a pair of sliders 18 are attached to the fastener body 16, a male member 70 is attached to one slider 18, and a female member 72 is attached to the other slider 18. The male leg 74 of the male member 70 is opposed to the receiving space 86 between the upper surface 82 and the lower surface 84 of the female member 72. Then, the pair of sliders 18 are moved closer to each other, the male-shape portion leg portion 74 of the male member 70 is inserted into the housing space 86 of the female member 72, and the pair of male-shape portion leg portions 74 are guided by the engagement portion 88 to be elastically deformed and moved closer to each other. After passing through the engaged portion 88, the elastic deformation of the male leg portion 74 is restored, and the male leg portion is engaged with the engaged portion 88 and cannot be pulled out. Thereby, the pair of sliders 18 are coupled to each other. At this time, the side edge portions of the pair of male leg portions 74 near the front surface 32f are positioned outside the slit 90 of the female member 72. When the pair of sliders 18 are disconnected from each other, the side edges of the male leg portions 74 located outside the slits 90 of the female member 72 are pressed to approach each other. The male-shaped leg portion 74 is elastically deformed to be separated from the engaged portion 88, and can be pulled out from the housing space 86 to be disconnected.
The fastener 68 according to the present embodiment has the same effects as those of the above-described embodiments. Since the male member 70 is engaged with and disengaged from the female member 72, the attachment and detachment operation is easy and the engagement strength is high.
The fastener for a slide fastener according to the present invention is not limited to the above-described embodiments, and may be attached to an existing slider in an easily attachable and detachable manner, may be coupled to each other by a simple operation, or may be easily provided with another function. The shapes of the engaging convex portion and the engaging groove portion can be appropriately changed, and for example, the engaging convex portion 44 may be a shape protruding outward from at least one of the side edge portion 32a of the upper portion 32, the side edge portion 38c of the lower portion 38, and the coupling portion 36, and may be appropriately changed as long as it is reliable and detachable and has high coupling strength. The shapes of the upper and lower portions attached to the slider can be changed appropriately in accordance with the slider.
