Hereinafter, embodiments of the slide fastener of the present invention will be described with reference to the drawings. Fig. 1 and 2 show an embodiment of the present invention, and as shown in fig. 16, the slide fastener of this embodiment is a slide fastener 11 in which a male slider 60 and a female slider 62 which can be coupled to each other are attached to fastener elements 16 of a fastener stringer 12 which can be opened and closed, and a coupling fastener bottom stop 10 is provided at an end portion of the fastener stringer 12. The lower stop 10 for the coupling fastener is attached to the male slider 60 side of the fastener stringer 12. The fastener tape portion 12 is provided with a pair of fastener tapes 14, and fastener elements 16 are provided on adjacent side edge portions of the pair of fastener tapes 14 so as to face each other.

The connecting fastener bottom stop 10 is attached to the vicinity of the longitudinal end of the fastener tape portion 12 so as to cover the fastener elements 16 in a state where the pair of fastener tapes 14 are closed by the fastener elements 16. The coupling fastener bottom stop 10 is provided with a front member 18 positioned on the front surface (obverse surface) 12a of the fastener stringer 12 and a back member 20 positioned on the back surface (reverse surface) 12b of the fastener stringer 12 so as to engage with each other. Fig. 1 is a perspective view of the coupling fastener bottom stop 10 as viewed from the front surface 12a of the fastener chain portion 12, and the front member 18 can be seen. Fig. 2 is a perspective view of the coupling fastener bottom stop 10 as viewed from the back surface 12b of the fastener chain portion 12, and the back member 20 can be seen.

First, the front member 18 connecting the slide fastener bottom stops 10 will be described with reference to fig. 3 and 4. The watch member 18 is a rectangular plate body that is long in the longitudinal direction of the fastener chain portion 12. Fig. 3 (a) is a perspective view showing the outer side surface 18a located on the opposite side of the fastener chain portion 12, and the outer side surface 18a is formed of a curved surface having a slightly higher center and being smooth. The receiving space 22 into which the body 64 of the male slider 60 to be described later is fitted is provided in a recessed shape at one end 18b of the front member 18 in the longitudinal direction. The housing space 22 is provided so as to penetrate the thickness of the watch member 18, and the housing space 22 is formed by opening to the outer surface 18a and the inner surface 18c on the opposite side of the outer surface 18 a. The housing space 22 is a rectangle surrounded by a pair of end edges 22a crossing at substantially right angles to the end 18b and an end edge 22b connecting the opposite ends of the pair of end edges 22a to the end 18b and being parallel to the end 18b, and the interval between the portions of the end edges 22a close to the end 18b is increased.

Fig. 3 (b) is a perspective view showing the inner surface 18c that abuts against the fastener chain portion 12, and is formed in a flat surface. An accommodation groove portion 24 is provided at the center of the inner surface 18c, and the accommodation groove portion 24 communicates with the end edge portion 22b of the accommodation space 22 and the end portion 18d on the opposite side from the end portion 18 b. The receiving groove portion 24 is formed to a predetermined depth from the inner surface 18c and has a depth into which the fastener element 16 is fitted. The housing groove portion 24 penetrates along the longitudinal direction of the cover 18, and has a width intersecting the longitudinal direction, in which the central portion is wider, the end portion communicating with the end edge portion 22b and the end portion 18d is slightly narrower, and the narrower portion is a width in which the fastener elements 16 can be fitted in a state of being engaged with each other.

An insertion projection 26 is provided at the center of the housing groove 24. The insertion projection 26 is erected substantially at right angles from the bottom 24a of the housing groove 24, and the cross-sectional shape of the insertion projection 26 parallel to the bottom 24a is elongated along the longitudinal direction of the watch component 18, and is formed at both ends of the watch component 18 in the longitudinal direction so as to be acute angles that become narrower toward the tip. A projection surface 26a of the insertion projection 26 on the side opposite to the bottom 24a of the housing groove 24 is formed higher than the inner surface 18c and is a plane parallel to the inner surface 18 c. A fitting portion 28 is integrally provided on the projecting surface 26a at a position close to the end portion 18 b. The fitting portion 28 is a rectangular plate-like body having a surface parallel to the projection surface 26a, and is surrounded by two sides along the longitudinal direction of the watch member 18 and two sides intersecting at substantially right angles to the longitudinal direction. The width of the fitting portion 28 intersecting the longitudinal direction is wider than the width of the insertion projection portion 26 intersecting the longitudinal direction, and a part thereof protrudes laterally on both sides of the insertion projection portion 26.

On the inner surface 18c, in the vicinity of the end 18d, there are provided convex portions 30 protruding from the inner surface 18c, and 1 convex portion 30 is provided on each side of the housing groove portion 24. A recessed portion 32 is provided on the side opposite to the end portion 18d so as to be close to the convex portion 30, and 1 recessed portion 32 is provided on each of both sides of the housing groove portion 24.

Next, the back member 20 connecting the slide fastener bottom stops 10 will be described with reference to fig. 5 and 6. The back member 20 is a rectangular plate body that is long in the longitudinal direction of the fastener chain portion 12 in the same shape as the front member 18. Fig. 5 (a) is a perspective view showing an inner side surface 20c abutting against the fastener stringer 12, and fig. 5 (b) is a perspective view showing an outer side surface 20a located on the opposite side of the fastener stringer 12.

The inner side surface 20c is formed in a flat surface, and the end 20b opposite to the end 18b of the front member 18 is provided with a housing space 34 into which a body 64 of a male slider 60 to be described later is fitted. The housing space 34 is formed by cutting out a part of the thickness of the back member 20 to a predetermined depth, and has the same shape as the housing space 22 of the front member 18. The corner of the bottom 34a of the housing space 34, which is continuous with the end 20b and has a large thickness, is chamfered in both directions to form an acute angle. The chamfered inclined surface on the bottom portion 34a side serves as a male slider guide surface 36 which abuts against the male slider 60 and guides the male slider 60 to the housing space 34. The chamfered inclined surface on the outer surface 20a side opposite to the bottom 34a serves as the locking member guide surface 38 that abuts against the female slider 62 and releases the connection with the male slider 60. An end portion 34b of the bottom portion 34a of the housing space 34, which is continuous with the end portion 20b, is provided with a rectangular cutout 40 at the center. The cutout portion 40 has a shape into which a hook portion 76 of the male slider 60, which will be described later, is fitted.

The locking hole 42 is provided from the center of the inner surface 20c to the vicinity of the end 20d opposite to the end 20 b. The locking hole 42 is for inserting and locking the insertion projection 26 and the fitting portion 28 of the watch component 18. The locking hole 42 is formed so as to penetrate through the thickness of the back member 20, communicate with the outer surface 20a and the inner surface 20c, and is a rectangle surrounded by two sides along the longitudinal direction of the back member 20 and two sides intersecting at substantially right angles to the longitudinal direction. An elastic piece 44 having a thickness smaller than that of the back member 20 is integrally provided at a position flush with and continuous to the outer surface 20a at a side edge portion 42a of the locking hole 42 located in the vicinity of the end portion 20 d.

The elastic piece 44 is a small rectangle fitted with a margin to the locking hole 42, and protrudes from the side edge portion 42a toward the center of the locking hole 42, and the tip end portion 44a of the elastic piece 44 reaches a position slightly beyond the center of the locking hole 42. The elastic piece 44 is formed thinner than the back member 20, and therefore, when viewed from the outer side surface 20a, it appears to be flush and continuous with the outer side surface 20a and closes the inside of the locking hole 42 with a slight margin, and when viewed from the inner side surface 20c, it appears that only the locking hole 42 is open. A rectangular space surrounded by the front end portion 44a of the elastic piece 44 and the side edge portion 42b of the locking hole 42 on the side opposite to the side edge portion 42a has a rectangular shape in which the fitting portion 28 is fitted with a slight margin. On the inner surface 20c side of the elastic sheet 44, a distal end portion 44a and an abutting portion 46 shaped like japanese character コ along a pair of side edge portions continuous to the distal end portion 44a are integrally provided so as to protrude in the thickness direction of the elastic sheet 44. The protruding length of the abutting portion 46 is such that the tip end portion 44a of the elastic piece 44 is high, gradually decreases toward the base end portion of the elastic piece 44, that is, toward the side edge portion 42a of the locking hole 42, and finally is flush with the elastic piece 44.

A fitting portion holding portion 48 having a thickness smaller than that of the back member 20 is provided at a position flush with and continuous to the inner surface 20c in the side edge portion 42b of the locking hole 42 and the pair of side edge portions continuous to the side edge portion 42 b. The fitting portion holding portion 48 has a size reaching from the side edge portion 42b of the locking hole 42 to the vicinity of the distal end portion 44a of the elastic piece 44. A thin cutout 50 is provided along the longitudinal direction at the center of the fitting portion holding portion 48. The cutout 50 is formed to have a width for fitting the insertion protrusion 26 of the front member 18, so that the insertion protrusion 26 of the front member 18 is inserted from the inner surface 20c when the front member 18 and the back member 20 are combined. The insertion projection 26 does not reach the outer surface 20a, and the end of the cutout 50 on the side of the side edge 42b slightly exceeds the side edge 42b to a position close to the end 20b, and the portion between the end and the outer surface 20a is not cut away and remains. On the outer surface 20a side of the fitting portion holding portion 48, a fitting portion guide surface 52 formed of a slightly recessed curved surface is provided at an end edge portion of the fitting portion holding portion 48 on the side edge portion 42a side. The fitting portion guide surface 52 is inclined so as to be closer to the outer surface 20a as it is closer to the side edge portion 42b, and when the front member 18 and the back member 20 are assembled, it comes into contact with the surface of the fitting portion 28 on the insertion projection 26 side to guide the fitting portion 28 to the space on the side edge portion 42b side of the locking hole 42. Since the fitting portion holding portion 48 is formed thinner than the back member 20, it appears to be flush and continuous with the inner side surface 20c when viewed from the inner side surface 20c, and it appears that only the locking hole 42 is open when viewed from the outer side surface 20 a.

The vicinity of the end 20d of the inner surface 20c is provided with a recess 54 recessed from the inner surface 20c, and 1 recess 54 is provided on each side of the locking hole 42. A convex portion 56 is provided in the vicinity of the concave portion 54 on the side opposite to the end portion 20d, and 1 convex portion 56 is provided on each of both sides of the locking hole 42.

Next, a method of attaching the coupling fastener bottom stop 10 to the fastener tape portion 12 will be described. At the attachment position of the fastener stringer 12, the engagement of the fastener elements 16 of the pair of fastener tapes 14 is released to form the open portion 17, and as shown in fig. 3 (b), the insertion protrusion 26 and the fitting portion 28 of the surface member 18 are inserted from the front surface 12a of the fastener stringer 12 into the open portion 17. The back member 20 is brought into contact with the open portion 17 from the back surface 12b of the fastener chain portion 12, and the protruding insertion protrusion 26 and the fitting portion 28 are inserted to a position close to the side edge portion 42a of the locking hole 42. At this time, the end 18d of the front member 18 is offset from the end 20d of the back member 20.

Next, the back member 20 is slid in a direction in which the end 20d approaches the end 18 d. The surface of the fitting portion 28 on the insertion projection 26 side is guided to overlap the fitting portion holding portion 48 over the fitting portion guide surface 52 of the fitting portion holding portion 48, and at this time, the front member 18 and the back member 20 can slide without being separated while sandwiching the fastener chain portion 12. Then, the abutting portion 46 of the elastic piece 44 abuts against the fitting portion 28, and as the height of the abutting portion 46 increases, the elastic piece 44 elastically deforms outward as shown in fig. 7.

When the back member 20 is further slid and the abutting portion 46 of the elastic piece 44 passes through the fitting portion 28, that is, when the tip end portion 44a of the elastic piece 44 passes through the fitting portion 28, the elastic piece 44 is elastically deformed and restored, and as shown in fig. 8, 9, and 10, the fitting portion 28 is fitted in a position close to the side edge portion 42b of the locking hole 42 and is not slidable. At this time, the end 18d of the front member 18 and the end 20d of the back member 20 are aligned.

This completes the attachment of the coupling fastener bottom stop 10 to the fastener stringer 12. The convex portion 30 of the front member 18 is inserted into the concave portion 54 of the back member 20 with the fastener tape 14 of the fastener tape portion 12 sandwiched between the concave portion 54 of the back member 20, and the convex portion 56 is also inserted into the concave portion 32 with the fastener tape 14 sandwiched between the concave portion 32, so that the coupling fastener bottom stop 10 does not move in the longitudinal direction of the fastener tape portion 12. Further, when the lower stop for the coupled fastener 10 is to be detached from the fastener chain portion 12, the elastic piece 44 is elastically deformed outward, and the back member 20 is slid with a strong force and passed through the fitting portion 28, so that the lower stop for the coupled fastener 10 can be detached.

As shown in fig. 16, the bottom stopper 10 for a coupling slide fastener is attached to the end of the fastener stringer 12 on the male slider 60 side of the male slider 60 and the female slider 62 for opening and closing the fastener stringer 12, and prevents the male slider 60 and the female slider 62 from coming off the fastener stringer 12. The fastener element 16 between the male slider 60 and the female slider 62 becomes the opening portion 17 after the engagement is released, and the outside of the male slider 60 and the outside of the female slider 62 become a state of being engaged and closed. The male slider 60 and the female slider 62 are coupled to each other when they are in contact with each other, and slide together. In the coupled state, the fastener elements 16 are engaged and closed regardless of the direction of sliding. When the male slider 60 and the female slider 62 are in contact with the connecting slide fastener bottom stop 10 in a connected state, the connection between the male slider 60 and the female slider 62 is released.

Next, the male slider 60 will be described with reference to fig. 11 and 12. The male slider 60 includes: a main body 64 that opens and closes the fastener elements 16 of the fastener tape portion 12; a pull tab 66 for manipulating the body 64; and a pull tab attachment portion 68 that retains the pull tab 66 to the outer side of the body 64.

The main body 64 is provided with: an upper plate 64a that sandwiches the fastener elements 16 of the fastener element portion 12 from the surface 12 a; and a lower plate 64b that sandwiches the fastener elements 16 of the fastener tape portion 12 from the back surface 12b, and a coupling post 70 is provided between the upper plate 64a and the lower plate 64 b. The coupling post 70 is provided at an end portion 60a of the upper plate 64a and the lower plate 64b in the direction in which the fastener element 16 is separated. The space between the upper plate 64a and the lower plate 64b is a guide path 72 through which the fastener element 16 passes, the end portion 60a side of the guide path 72 separated from the fastener element 16 is divided in two directions by the coupling post 70, the guide path 72 is formed in a Y-shape by 1 space on the end portion 60b side where the fastener elements 16 are engaged, and the widths of the upper plate 64a and the lower plate 64 are narrowed as approaching the end portion 60 b. A guide edge portion 74 that covers a gap between the upper plate 64a and the lower plate 64b is provided at a side edge portion of the upper plate 64a near the end portion 60 b. The guide edge portion 74 protrudes at substantially right angles to the surface of the upper plate 64a toward the side edge portion of the lower plate 64b, and a space through which the fastener tape 14 of the fastener tape portion 12 can pass is provided in a slit shape between the tip end of the guide edge portion 74 and the lower plate 64 b. The guide edge portion 74 guides the slide of the main body 64 along the fastener element 16.

A hook 76 is provided on the outer surface of the lower plate 64b on the side opposite to the upper plate 64 a. The hook 76 is provided on the lower plate 64b near the end 60 a. The hook portion 76 has a quadrangular prism-shaped shaft portion 78, the quadrangular prism-shaped shaft portion 78 has two side surfaces substantially parallel to the end portions 60a, 60b and two side surfaces substantially perpendicular to the end portions 60a, 60b, and a side surface 78a of the shaft portion 78 facing the end portion 60a is an inclined surface which is distant from the end portion 60a as being distant from the lower plate 64 b. A locking projection 80 is provided at the distal end of the shaft 78, and projects from a side surface 78b opposite to the side surface 78a and facing the end 60 b. The shaft portion 78 is chamfered at the corners on both sides of the side surface 78b to provide relief portions 79.

Next, the female slider 62 will be described with reference to fig. 13, 14, and 15. The female slider 62 is provided with a body 64, a pull tab 66, a pull tab attachment portion 68, a connecting post 70, a guide path 72, and a guide edge portion 74, similarly to the male slider 60. The side of the female slider 62 from which the fastener elements 16 are separated is an end portion 62a, and the side from which the fastener elements 16 are engaged is an end portion 62 b.

An attachment projection 84 to which an elastic locking member 82 to be described later is attached is integrally provided on an outer surface of the lower plate 64b of the female slider 62 on the side opposite to the upper plate 64 a. The mounting projection 84 is provided with: a pillar portion 84a projecting outward at substantially right angles to the lower plate 64 b; and a plate portion 84b provided at the front end of the pillar portion 84a, and extending to both sides of the pillar portion 84a to be flanged. The plate portion 84b is a plate body parallel to the lower plate 64 b. The attachment projection 84 is provided adjacent to the end portion 62b of the female slider 62, and the plate portion 84b has a substantially trapezoidal shape with one side aligned with the end portion 62b, and the shorter side on the side opposite to the end portion 62b reaches near the center of the lower plate 64 b.

An elastic locking member 82 as another member is attached to the female slider 62. The elastic locking member 82 is made of a synthetic resin having an appropriate composition. As shown in fig. 15, the elastic locking member 82 is a plate body that is long in one direction, and when attached to the female slider 62, the elastic locking member 82 is attached so that the longitudinal direction thereof is substantially parallel to the direction in which the end portion 62a and the end portion 62b of the female slider 62 are connected, that is, the direction in which the fastener element 16 is inserted, and is longer than the female slider 62 in the longitudinal direction. One surface of the elastic locking member 82 is an upper surface 82a overlapping the lower plate 64b of the female slider 62, and the opposite side is a lower surface 82 b. One end 82c in the longitudinal direction is attached to the end 62b of the female slider 62, and the other end 82d in the longitudinal direction protrudes laterally from the end 62a of the female slider 62.

The end portion 82c is provided with a pair of attachment hook portions 86, and the pair of attachment hook portions 86 are attached by sandwiching the post portion 84a of the attachment projection 84 of the female slider 62 from both sides. An engaging projection 87 is provided in the middle near the base ends of the pair of attachment hooks 86. The engaging projection 87 is adjacent to the plate portion 84b of the mounting projection 84 of the female slider 62 when the elastic locking member 82 is mounted to the female slider 62, and smoothes the step between the mounting projection 84 and the lower surface 82 b.

An end 82d and a wall 88 shaped like japanese コ extending along a pair of side edges continuous with the end 82d are integrally provided on the lower surface 82b of the elastic locking member 82 so as to protrude in the thickness direction of the elastic locking member 82. The protruding length of the wall portion 88 is higher at the end 82d, gradually decreases toward the end 82c, and becomes flush with the lower surface 82b in the vicinity of the engaging projection 87. The outer surface of the wall portion 88 at the end portion 82d is formed by an inclined surface 90 that is directed outward in the longitudinal direction as it is separated from the lower surface 82 b. An abutment projection 92 projecting from the abutment surface 90 is provided substantially at the center of the abutment surface 90.

A through hole 94 into which the hook portion 76 of the male slider 60 is fitted and locked is provided substantially at the center of a portion of the elastic locking member 82 surrounded by the wall portion 88 shaped like japanese character コ. The through hole 94 is formed long along the longitudinal direction of the elastic locking member 82, the end portion on the attachment hook 86 side is formed by a curved line bulging toward the attachment hook 86, and the end portion on the abutment projection 92 side is formed by a straight line substantially perpendicular to the longitudinal direction. A step portion 96 having a smaller thickness than the lower surface 82b is provided in a peripheral portion of the through hole 94 on the lower surface 82b side. A locking recess 98 is provided in a straight end portion of the through hole 94 near the end portion 82d, and is formed by slightly partially cutting and recessing the inner surface 88b of the wall portion 88. The locking recess 98 receives the locking projection 80 of the shaft portion 78 of the male slider 60 by being inserted thereinto. The stepped portion 96 and the locking recess portion 98 are provided to have substantially the same depth.

The elastic locking member 82 is attached to the female slider 62 by the following method: the end 82c of the elastic locking member 82 is pressed from the end 62a side toward the mounting projection 84 of the female slider 62. The pair of attachment hook portions 86 are formed at intervals narrower than the thickness of the stay portion 84a, and when pressed against the stay portion 84a, elastically deform to be wider, and allow the stay portion 84a to pass therethrough. After the post portion 84a passes, the elastic deformation of the pair of attachment hook portions 86 is restored, and the post portion 84a becomes unable to pass and is locked. Thereby, the attachment of the elastic locking member 82 to the female slider 62 is completed.

Next, a method of using the bottom stop 10 for connecting the slide fastener will be described. As shown in fig. 16, the male slider 60 is attached to the end 18b side of the front member 18 of the attached coupling fastener bottom stop 10 of the fastener stringer 12. At this time, the end 60b of the male slider 60 is positioned close to the coupling slide fastener bottom stop 10. The female slider 62 is attached to a portion of the fastener stringer 12 on the opposite side of the male slider 60 from the connecting fastener bottom end 10. At this time, the end 62a of the female slider 62 is positioned close to the end 60a of the male slider 60. An end 82d of the elastic locking member 82 attached to the female slider 62 projects toward the male slider 60.

As shown in fig. 16 and 17, in a state where the male slider 60 and the female slider 62 are not coupled, the pull-tab 66 attached to the pull-tab attachment portion 68 is held and pulled, whereby the male slider 60 and the female slider 62 move independently along the fastener stringer 12. The fastener element 16 between the male slider 60 and the female slider 62 becomes the release portion 17 from which the engagement is released, and the fastener tape portion 12 is in an open state, and the outer side of the end 60b of the male slider 60 and the outer side of the end 62b of the female slider 62 become a state in which the fastener element 16 is engaged and closed.

As shown in fig. 18, when the female slider 62 is brought close to the male slider 60, the elastic locking member 82 attached to the female slider 62 abuts on the male slider 60. The abutting projection 92 of the elastic locking member 82 abuts against the side surface 78a of the hook portion 76 of the male slider 60, and when the female slider 62 is brought closer to the male slider 60, the elastic locking member 82 is separated from the fastener tape portion 12 along the side surface 78a, and the female slider 62 bends and tilts the fastener tape portion 12.

As shown in fig. 19, when the contact projection 92 passes over the side surface 78a, the hook portion 76 of the male slider 60 is inserted into the through hole 94 of the elastic locking member 82. The inclination of the female slider 62 is eliminated, and the end 60a of the male slider 60 and the end 62a of the female slider 62 are connected to each other and connected to each other. The locking projection 80 of the hook portion 76 of the male slider 60 is fitted into the locking recess 98 of the elastic locking member 82 and locked with an appropriate strength.

In this state, even if a force is applied in a direction in which the male slider 60 and the female slider 62 are separated from each other, the hook portion 76 of the male slider 60 is brought into contact with the edge of the through hole 94 of the elastic locking member 82 of the female slider 62 on the locking recess 98 side and is not separated. Further, even if a force is applied in a direction in which the male slider 60 and the female slider 62 are brought close to each other, since the end 60a of the male slider 60 and the end 62a of the female slider 62 are adjacent with a slight gap, even if the ends 60a and the ends 62a abut against each other, a length required for disengaging the locking projection 80 of the hook portion 76 from the through hole 94 of the elastic locking member 82 is insufficient, and disengagement is not caused. Since the male slider 60 and the female slider 62 are connected, the fastener elements 16 are closed over the entire length, and cannot be opened even when the male slider 60 and the female slider 62 are moved.

Next, when the male slider 60 and the female slider 62 are to be disconnected from each other, the male slider 60 is brought into contact with the connecting fastener bottom stop 10. As shown in fig. 20, when the male slider 60 and the female slider 62 connected to each other are brought into contact with the lower stop 10 for the connected slide fastener, first, the end portion 60b side of the plate 64b of the male slider 60 is brought into contact with the guide surface 36 for the male slider of the lower stop 10 for the connected slide fastener and guided, the lower plate 64b enters the housing space 34 of the back member 20, and the upper plate 64a enters the housing space 22 of the surface member 18.

As shown in fig. 21, the elastic locking member 82 of the female slider 62 abuts against the back member 20 connecting the slide fastener bottom stops 10 while the male slider 60 is accommodated in the accommodating spaces 22 and 34. The abutting surface 90 of the elastic locking member 82 abuts against the locking member guide surface 38, and when the female slider 62 is moved closer to the coupling fastener bottom stop 10, the elastic locking member 82 moves away from the fastener stringer 12 along the locking member guide surface 38, and the female slider 62 bends and tilts the fastener stringer 12. The engagement between the locking projection 80 of the male slider 60 and the through hole 94 of the elastic locking member 82 has strong attachment strength in a direction separating from each other along the fastener stringer 12, but the attachment strength is weak in a direction separating from the fastener stringer 12, and the elastic locking member 82 is easily separated from the locking projection 80. Since the contact projection 92 is located at the center of the contact surface 90, it does not come into contact with the guide surfaces 38 for the locking members provided on the left and right sides, but is inserted into the cutout 40 together with the hook portion 76 without hindrance.

As shown in fig. 22, when the male slider 60 and the female slider 62 are further brought closer to the bottom stop 10 for the connecting slide fastener, the male slider 60 enters a position where the end portion 60b abuts against the end edge portion 22b of the housing space 22, and is fitted into the housing spaces 22 and 34, the hook portion 76 is fitted into the cutout portion 40, and the male slider 60 is smoothly housed in the bottom stop 10 for the connecting slide fastener. At this time, the engagement of the female slider 62 is released. When a force is applied to the female slider 62 in a direction away from the male slider 60, the female slider 62 is separated from the male slider 60, and the fastener element 16 is opened.

The slide fastener 11 to which the connecting slide fastener bottom stop 10, the male slider 60, and the female slider 62 are attached is attached to an opening of a bag, not shown. When the male slider 60 and the female slider 62 are coupled, the fastener elements 16 do not open even if the male slider 60 and the female slider 62 are moved. This enables safe storage of valuables and the like stored in the case. When the contents in the bag are taken out, the male slider 60 and the female slider 62 are moved to positions where they are stored in the connecting slide fastener bottom stop 10, the connection is released, and the female slider 62 is moved in a direction away from the male slider 60. This opens the fastener elements 16, and the case can be opened. By moving the male slider 60 and the female slider 62 to arbitrary positions, the open portion 17 of the fastener stringer 12 can be provided at an arbitrary position.

According to the bottom stop 10 for a coupled slide fastener of the slide fastener 11 of this embodiment, it is possible to easily attach the bottom stop to an arbitrary position of the fastener stringer 12 with a simple structure, and prevent the coupled male slider 60 and female slider 62 from coming off the fastener stringer 12 without moving from the predetermined position of attachment. Further, the male slider 60 and the female slider 62 can be reliably disconnected from each other only by bringing the male slider 60, to which the female slider 62 is connected, into contact with the bottom stop 10 for connecting the slide fastener, and the operability is good. The fastener elements 16 can be opened when necessary, and the male slider 60 and the female slider 62 can be coupled by a simple operation when not necessary so that the fastener elements 16 are not opened. The bottom stop 10 for the connecting zipper can be attached to an opening of a bag or the like, and securely holds the valuables or the like stored therein.

The bottom stop 10 for a coupling fastener of the slide fastener 11 of this embodiment is a bottom stop for a coupling fastener in which the front member 18 and the back member 20 are elastically attached to the fastener chain portion 12 by being sandwiched between the front surface 12a and the back surface 12b of the fastener chain portion 12, and is easy to attach, does not require tools, and has good work efficiency. The surface member 18 and the back member 20 are attached to each other by locking the elastic piece 44 of the back member 20 to the fitting portion 28 of the surface member 18, and the fitting portion 28 is prevented from returning and not inadvertently coming off. The connecting fastener bottom stop 10 is provided with the male slider guide surface 36, and guides the male slider 60 to the housing spaces 22 and 34 while contacting the lower plate 64b of the male slider 60, so that the male slider 60 can be easily fitted into the housing spaces 22 and 34. Further, the coupling fastener bottom stop 10 is provided with the locking member guide surface 38, and the elastic locking member 82 can be easily moved in a direction away from the fastener tape portion 12 only by bringing the elastic locking member 82 into contact and further closer, so that the coupling of the male slider 60 and the female slider 62 can be easily released.

The front member 18 and the back member 20 can be attached to the fastener stringer 12 with the end 18b and the end 20b facing each other, and the fastener elements 16 including the fastener stringer 12 are provided with the housing spaces 22 and 34 inside, so that the male slider 60 can be smoothly inserted and fitted. Since the fastener stringer 12 is flexible, the male slider 60 may be bent when the male slider 60 is moved vigorously, but even if the fastener stringer 12 is bent, the male slider 60 can be smoothly fitted to the connecting fastener bottom end stop 10. The fitting can be easily performed even with one hand, and the operability is good.

The male slider 60 and the female slider 62 can be connected simply and reliably only by inserting and locking the hook portion 76 of the male slider 60 into the through hole 94 of the elastic locking member 82 of the female slider 62.

A step portion 96 is provided in the peripheral edge portion of the through hole 94 of the elastic locking member 82, and the step portion 96 and the locking recess 98 locking the locking projection 80 of the male slider 60 have the same depth, so that even if the male slider 60 is twisted and the locking projection 80 is disengaged from the locking recess 98, the connection is maintained and the connection is not inadvertently released. Further, the shaft portion 78 of the hook portion 76 is formed with the relief portion 79, and even if the male slider 60 is twisted, the coupling is maintained in this point because a margin is provided on the inner peripheral surface of the through hole 94.

Further, since the convex portions 30 and 32 of the surface member 18 and the concave portions 54 and 56 of the back member 20 are engaged with each other with the fastener tape 14 sandwiched therebetween, the connecting fastener bottom stop 10 does not move, and even if the male slider 60 is strongly abutted, the male slider does not deviate from the attachment position. The ring member and the sewing thread for locking the connecting slide fastener bottom stop 10 so as not to be deviated are not required, and the manufacturing is simple. Further, since there is no hole or projection on the outer surface 18a of the watch member 18, the appearance is neat, and therefore, the watch member can be attached to various articles without discomfort, and a mark or the like can be formed, thereby improving design.

The slide fastener of the present invention is not limited to the above embodiment, and can be modified as appropriate. The slide fastener using the lower stopper for the coupling slide fastener can be used for various articles outside the case. The structure of the attachment surface member and the back member can be changed, and any structure may be used as long as it is simply and reliably attached to the fastener stringer. The position and structure of the projection and the recess that prevent movement with respect to the fastener chain portion can be changed as long as they are reliably locked to the position and structure of the fastener chain portion. When the convex portion and the concave portion are not necessary, the convex portion and the concave portion may be absent, and the attachment strength to the fastener chain portion may be adjusted by adjusting the height and the depth, or may be moved when a certain force is applied. The material of the bottom stop for connecting the slide fastener, the finish of the surface, and the like can be freely changed.
