Description

Technical Field

[0001] The utility model relates to a slider. Background Art

[0002] Japanese Patent Application Laid-Open No. 9-294612 (Patent Document 1) describes a slider having a stop mechanism using a stop member (claw lever). The stop mechanism of the slider is a structure that functions to hold the slider stopped relative to the element row after the slider is slid so that the slider does not move from its stopped position (hereinafter referred to as a stop function).

[0003] In the slider stop mechanism described in Patent Document 1, for example, when a finger releases the slider after sliding the slider using the pull tab, the elastic force applied to the stop member causes a claw provided on the stop member to enter the element guide path of the slider body and engage with the zipper element. This maintains the slider in the stopped position relative to the element array.

[0004] Patent Document 1 describes that when a slider is formed of four components, for example, a slider body, a handle, a stopper, and a cover, all of the four components can be formed of synthetic resin.

[0005] In fact, the slider with a stop mechanism described in Patent Document 1 is applied to a slide fastener of a type in which a plurality of fastener elements are formed by injection-molding a synthetic resin on a fastener tape, and has been put into practical use.

[0009] Problems to be solved by utility models

[0010] As one of slide fasteners, there is known a slide fastener in which a synthetic resin monofilament is spirally formed to form fastener elements, and the spiral fastener elements are then attached to a fastener tape by sewing.

[0011] A slide fastener in which fastener elements are formed by spirally molding a monofilament is completely different from a slide fastener in which fastener elements are formed by injection molding of a synthetic resin in terms of the shape of the fastener elements and the means of fixing the fastener elements to the fastener tape.

[0012] Furthermore, in the past, when a slider with a stop mechanism was used in a zipper having spiral zipper elements, the stop member, which is one of the components of the slider, was generally formed of metal. Such metal stop members differed from the synthetic resin stop members described in Patent Document 1, for example, in terms of material, strength, and formability, and therefore had different shapes.

[0013] In recent years, awareness of recycling has been increasing. Therefore, in order to improve reusability, it is required to manufacture sliders with a stop mechanism using only synthetic resin components without using metal components.

[0014] However, when a slider having a stop member made of synthetic resin is applied to a zipper having spiral zipper teeth, if a simple improvement is made, for example, by simply changing the size of the stop member described in Patent Document 1 to correspond to the spiral zipper teeth, the claw of the stop member cannot be properly engaged with the zipper teeth after the sliding of the slider is stopped.

[0015] Furthermore, even if the claw of the stop member engages with the zipper element, the engaged claw may easily come off the zipper element due to, for example, the swinging of the pull tab, thereby releasing the engagement. Therefore, compared with spiral zipper elements, the stop member made of synthetic resin cannot stably perform the stopping function of stopping the slider.

[0016] The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a slider capable of stably exhibiting the stopping function of the stopping member even when the stopping member is formed of a synthetic resin.

[0017] Solutions for solving problems

[0018] The cam is secured to the rear of the slider and has a cam portion which is adapted to engage the slider and to engage with the rear end of the slider so that the slider can be secured to the slider body. The neck portion extending rearward from the head portion, the base portion connected to the rear end portion of the neck portion, and at least one claw portion protruding from the bottom surface of the base portion, the stopping member having an axis relative to the inner circumference, the axis relative to the inner circumference being formed across the head portion, the neck portion, and the inner circumference of the base portion in a manner surrounding the mounting axis portion of the pull tab, and when the stopping member is viewed from the side in the width direction of the slider, when the position of the rearmost portion arranged at the axis relative to the inner circumference is defined as a reference position with respect to the front-to-back direction, at least one of the claw portions is located at a position forward of the reference position in the length direction of the slider.

[0019] In the slider of the present invention, it is preferred that the claw portion has a first claw portion and a second claw portion, and when viewed from the side of the stopping member, the first claw portion is located at a position forward of the reference position in the length direction of the slider, and the second claw portion is located at a position overlapping with the reference position in the length direction of the slider.

[0020] In this case, it is preferable that the lower end of the first claw be arranged farther from the bottom surface of the base portion in the slider height direction than the lower end of the second claw.

[0021] In the slider of the present invention, it is preferred that the bottom surface of the base portion has a central flat surface arranged between the first claw portion and the second claw portion along the length direction of the slider, and a rear flat surface arranged at a position farther rearward than the first claw portion and the second claw portion in the length direction of the slider and along the width direction of the slider, the upper wing plate has a claw hole extending from the upper surface of the upper wing plate to the chain tooth guide passage and a base mounting portion arranged in the claw hole and on which the base portion is mounted, and the base mounting portion has a T-shaped shape for supporting the central flat surface and the rear flat surface of the base portion.

[0022] In addition, it is preferable that a dimension of the base portion in the slider width direction is smaller than a dimension of the claw hole in the slider width direction.

[0023] Preferably, the first claw and the second claw respectively have outer side surfaces facing outward in the width direction of the slider, and the outer side surface of at least one of the first claw and the second claw has a rear inclined surface that gradually reduces the size of the first claw or the second claw in the width direction of the slider toward the rear.

[0024] Preferably, the first claw and the second claw respectively have outer side surfaces facing outward in the width direction of the slider, and the outer side surface of at least one of the first claw and the second claw has a downward inclined surface that causes the dimension of the first claw or the second claw in the width direction of the slider to decrease downward.

[0025] Preferably, the base portion of the stopping member has a rear upper end surface arranged at a position rearward of the connecting portion to which the neck is connected, and the rear upper end surface of the base portion has a rotation limiting surface. When the stopping member rotates in a direction in which the claw portion is disengaged from the chain tooth guide path, the rotation limiting surface abuts against a part of the cover body to limit the rotation of the stopping member.

[0026] Preferably, in the side view of the stop member, a surface or portion of the stop member disposed most forwardly of the rotation shaft portion is aligned or substantially aligned with a front end surface of the head facing forward.

[0027] Effect of utility model

[0028] According to the slider of the present invention, even when the stopping member is formed of synthetic resin, the stopping function of the stopping member can be stably exerted. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0039] The present inventors have conducted a detailed investigation into the reason why the claw portion of the stopper member does not properly engage with the fastener element when the stopper member made of synthetic resin described in Patent Document 1 is applied to a slide fastener having a spiral fastener element.

[0040] As a result, it was found that the sewing line for sewing the spiral zipper teeth on the zipper tape affects the engagement of the claw portion of the stop member and makes it difficult for the claw portion to engage with the meshing portion of the left and right zipper teeth in the tooth guide passage of the slider body.

[0041] Therefore, the inventors repeatedly conducted in-depth research based on the above reasons, and as a result, found a structure of the stop member that can appropriately engage the two claw portions with the left and right zipper teeth for the spiral zipper teeth in the zipper, thus completing the present utility model. Hereinafter, the slider of the embodiment of the present utility model will be described in detail with reference to the drawings.

[0042] Figure 1 It is an exploded perspective view schematically showing the state of the slider of the present embodiment after being disassembled. Figure 2 It is a side view schematically showing the stop member. Figure 3 and Figure 4 They are enlarged perspective views schematically showing a part of the stop member enlarged from different directions. Figure 5 and Figure 6 They are side views and top views schematically showing the slider body and the stop member, respectively.

[0043] In the following description related to the slider 1, the front-rear direction is the slider length direction (or the length direction of the cover 70), and is the direction along the sliding direction of the slider 1. In particular, in the zipper, the direction in which the slider 1 moves to engage the left and right tooth rows 5 is set as the front (shoulder side direction), and the direction in which the slider 1 moves to separate the tooth rows 5 is set as the rear (rear opening side direction).

[0044] The up-down direction is the slider height direction, for example, it is the direction orthogonal to the upper wing plate 11 and the lower wing plate 12 of the slider body 10. In this case, the direction in which the cover 70 (or the pull tab 40) is installed with respect to the slider body 10 of the slider 1 is set as the upper side, and the opposite direction is set as the lower side.

[0045] The left-right direction is the slider width direction, and is the direction orthogonal to the slider length direction and the slider height direction.

[0046] The slider 1 of the present embodiment is used for a zipper having a pair of left and right zipper tooth tapes, and the pair of left and right zipper tooth tapes are formed by sewing spiral zipper teeth 6 on the zipper tape using a sewing line (sewing thread and loop thread (Japanese: ルーバー糸)). In this case, a sewing portion 7 is formed by the intersection of the sewing thread and the loop thread of the sewing line, and a plurality of zipper teeth 6 are sewn on the zipper tape using the sewing portion 7 (refer to Figure 7 ). In addition, by the plurality of zipper teeth 6 sewn on the zipper tape, a tooth row 5 is formed on the side edge portion of the zipper tape.

[0047] The zipper slider 1 of this embodiment is slidably mounted on the left and right zipper element rows 5 of the zipper stringer. The slider 1 has, for example, a stop mechanism (automatic stop mechanism) such as the following, which automatically activates the stop function of the stop member 50 when the user's finger releases the pull tab 40 after sliding the slider 1.

[0048] The slider 1 is formed of four components: a slider body 10, a pull tab 40, a stop member 50, and a cover 70. All four components are formed from a thermoplastic synthetic resin. The slider body 10, pull tab 40, stop member 50, and cover 70 can each be manufactured by injection molding of a synthetic resin. Furthermore, in the present invention, the material of the slider 1 is not limited; for example, at least one of the slider body 10, pull tab 40, stop member 50, and cover 70 can be formed from metal.

[0049] The slider body 10 includes an upper wing plate 11, a lower wing plate 12 arranged parallel or approximately parallel to the upper wing plate 11, a connecting column 13 connecting the front end portion (shoulder side end portion) of the upper wing plate 11 and the front end portion (shoulder side end portion) of the lower wing plate 12, left and right flange portions 14 provided on the left and right side edges of the upper wing plate 11, and left and right lower side ribs 15 provided on the left and right side portions of the lower wing plate 12.

[0050] Left and right shoulder openings are formed at the front end of the slider body 10, sandwiching the connecting post 13. A rear opening is formed at the rear end of the slider body 10. A generally Y-shaped fastener element guide passage is formed between the upper wing plate 11 and the lower wing plate 12 of the slider body 10, connecting the left and right shoulder openings and the rear opening.

[0051] The left and right element rows 5 are passed through the element guide passage in the slider body 10. In this case, the left and right flanges 14 of the slider body 10 are formed so that the zipper elements 6 can be slidably contacted with the inner side surfaces of the flanges 14 to restrict the left and right positions of the zipper elements 6.

[0052] The left and right side edges of the slider body 10 are provided with tape insertion gaps for passing the zipper tape. The left and right tape insertion gaps are formed between the flange portion 14 and the lower rib portion 15 of the slider body 10.

[0053] The slider body 10 includes a front mounting post 21 extending upward from the front end of the upper wing plate 11, a rear mounting post 22 extending upward from the rear end of the upper wing plate 11, a pair of left and right mounting walls 26 extending rearward from the front mounting post 21, and a pull-tab guide 27 provided between the mounting walls 26 and the rear mounting post 22 in a side view of the slider body 10. The front mounting post 21, the rear mounting post 22, the mounting walls 26, and the pull-tab guide 27 are integrally provided on the upper wing plate 11.

[0054] The slider body 10 is provided with a housing recess 28 formed by being recessed from the upper surface of the upper wing plate 11 between the left and right mounting wall portions 26, a claw hole 31 penetrating the upper wing plate 11 in the vertical direction, and a base mounting portion 32 for mounting a base portion 54 (described later) of the stop member 50 in the claw hole 31.

[0055] The front mounting post 21 and the rear mounting post 22 of the slider body 10 each include a support post portion 23 extending upward from the upper wing plate 11 and an engaging claw portion 24 provided at the upper end of the support post portion 23. Steps 25 are provided along the front-to-back direction on the left and right side surfaces of the upper end of the front mounting post 21 and the left and right side surfaces of the upper end of the rear mounting post 22.

[0056] Each step 25 of the front mounting post 21 and the rear mounting post 22 is formed so that the portion above the step 25 of the front mounting post 21 or the rear mounting post 22 is smaller in the width direction than the portion below the step 25. With respect to the step 25 of the front mounting post 21 and the step 25 of the rear mounting post 22, when the cover 70 is attached to the slider body 10, an inner protrusion 73, described later, provided on the inner side of the cover 70 is positioned so as to contact the step 25 from above or to be close to the step 25 from above.

[0057] The engaging claw portion 24 of the front mounting post 21 protrudes forward from the support post portion 23. Furthermore, in a side view of the slider body 10, the engaging claw portion 24 of the front mounting post 21 is formed into a triangular shape having an inclined surface that slopes downward toward the front and a lower end surface parallel to the front-to-back direction. The engaging claw portion 24 of the rear mounting post 22 protrudes rearward from the support post portion 23. Furthermore, in a side view of the slider body 10, the engaging claw portion 24 of the rear mounting post 22 is formed into a triangular shape having an inclined surface that slopes downward toward the rear and a lower end surface parallel to the front-to-back direction.

[0058] Each of the left and right mounting walls 26 extends upward from the upper surface of the upper wing plate 11 in a thin plate-like shape. Each mounting wall 26 is arranged in the front-to-back direction from the support column 23 of the front mounting column 21 toward the rear. A gap is provided between the left and right mounting walls 26 to allow insertion of a head 51 of a stopper 50, described later.

[0059] Each of the left and right mounting walls 26 has an upper surface parallel to the upper surface of the upper wing panel 11, an inclined surface that slopes downward toward the rear, and an insertion recess 26a formed so as to be recessed downward from the upper surface of the mounting wall 26. The insertion recess 26a is provided at a position at or near the upper surface of the upper wing panel 11 in the vertical direction.

[0060] The left and right rotational shafts 52 (described later) of the stop member 50 are each inserted from the upper side into the insertion recesses 26a of the mounting wall 26. The insertion recesses 26a retain the inserted rotational shafts 52 in a rotatable manner and also retain the rotational shafts 52 in a vertically movable manner. The spacing between the insertion recesses 26a in the front-to-back direction is formed to be the same as, or slightly larger than, the diameter of the rotational shafts 52 of the stop member 50. The bottom surface (lower surface) of the insertion recesses 26a is formed into an arc shape in a side view of the slider body 10.

[0061] The upper surface of the mounting wall 26 is positioned at the same height as the stepped surface (upper surface) of the stepped portion 25 provided on the front mounting post 21. When the cover 70 is mounted on the slider body 10, the inner protrusion 73 of the cover 70 is positioned so as to contact the upper surface of the mounting wall 26 from above or to be close to the upper surface of the mounting wall 26 from above. As a result, the insertion recess 26a of the mounting wall 26 is blocked from above by the inner protrusion 73 of the cover 70. This prevents the rotation shaft 52 of the stopper 50, which is inserted into the insertion recess 26a of the mounting wall 26, from dislodging upward from the insertion recess 26a.

[0062] The pull-tab guide portion 27 includes left and right guide vertical wall portions 27a provided along the front-back direction and guide rib portions 27b provided along the left-right direction in a manner connecting the front ends of the left and right guide vertical wall portions 27a (see FIG. Figure 6 The left and right guide longitudinal walls 27a and guide ribs 27b surround a portion of the quadrilateral claw hole 31 provided in the upper wing plate 11 from the outside in a plan view of the slider body 10. The left and right guide longitudinal walls 27a are arranged at a position further outward than the left and right mounting walls 26 in the left-right direction.

[0063] In a side view of the slider body 10, the pull-tab guide portion 27 is formed into a triangular shape having a guide inclined surface that slopes downward toward the front and a rear end surface that faces rearward. Due to the provision of the pull-tab guide portion 27 and the inclined surface of the mounting wall portion 26 having such a guide inclined surface, for example, when the pull-tab 40 is tilted at an angle parallel to the upper wing plate 11, the mounting shaft portion 43 of the pull-tab 40, which will be described later, can be easily moved to a position between the mounting wall portion 26 and the pull-tab guide portion 27.

[0064] The storage recess 28 of the slider body 10 is, for example, viewed in a cross section perpendicular to the left-right direction of the slider body 10 (see FIG. Figure 8 ) has a shape that is concave downward and is provided rearward from the rear wall surface of the front mounting post 21. The storage recess 28 is formed to have a constant cross-sectional shape (or a constant space) from the left mounting wall portion 26 to the right mounting wall portion 26.

[0065] When assembling the slider 1, a portion of the head portion 51 of the stop member 50, which will be described later, is inserted into the receiving recess 28. The receiving recess 28 is formed to have a depth and size such that the head portion 51 of the stop member 50 does not contact the bottom surface of the receiving recess 28 even if the rotating shaft portion 52 of the stop member 50 moves up and down in the insertion recess 26a of the mounting wall portion 26. For example, when observing Figure 8 In the cross section, the bottom surface of the storage recess 28 is arranged above the lower surface of the upper wing plate 11 (the inner wall surface facing the element guide passage) in the up-down direction.

[0066] The claw hole 31 extends from the upper surface of the upper wing plate 11 to the element guide path. The claw hole 31 has a shape that is not visible when the slider body 10 is viewed from above (for example, referring to FIG. Figure 6 ) is a shape into which the stop member 50 (particularly, the base portion 54 of the stop member 50 described later) can be inserted. For example, in the case of this embodiment, the claw hole 31 is formed into a quadrilateral shape in a top view of the slider body 10 so as to correspond to the shape of the base portion 54 of the stop member 50. Figure 6 As shown, the claw hole 31 is provided in the left-right center portion of the upper wing plate 11. The claw hole 31 is provided between the left and right mounting wall portions 26 and the rear mounting column 22 in the front-rear direction.

[0067] A base placement portion 32 is provided in the claw hole 31. The base placement portion 32 is arranged at a position where the base portion 54 of the stopping member 50 can be placed when the first claw portion 55 and the second claw portion 56 of the stopping member 50, which will be described later, are inserted into the element guide path of the slider body 10 (i.e., when engaged with the fastener element 6).

[0068] Specifically, for example Figure 8 As shown, the base mounting portion 32 is disposed at the lower end of the claw hole 31, and a step is formed between the upper surface of the base mounting portion 32 and the upper surface of the upper wing plate 11. The lower surface of the base mounting portion 32 is formed continuously from the lower surface of the upper wing plate 11 without forming a step.

[0069] like Figure 6 As shown, the base mounting portion 32 of this embodiment includes a longitudinal mounting portion 32a disposed in the left-right center portion of the claw hole 31 along the front-back direction, and a transverse mounting portion 32b disposed in the left-right rear end portion of the claw hole 31. Specifically, the base mounting portion 32 has an inverted T-shape when viewed from above the slider body 10.

[0070] In particular, in the slider 1 of this embodiment, since the first claw portion 55 and the second claw portion 56 of the stop member 50 are arranged near the front end of the base portion 54 as described later, the base portion 54 of the stop member 50 has a shape that extends rearward of the first claw portion 55 and the second claw portion 56. Therefore, in the base mounting portion 32 of this embodiment, not only the vertical mounting portion 32a arranged in the center portion of the claw hole 31 in the left-right direction can be provided, but also the horizontal mounting portion 32b for mounting the portions of the first claw portion 55 and the second claw portion 56 that extend rearward of the base portion 54 can be provided.

[0071] In particular, in this embodiment, the vertical mounting portion 32a is formed relatively thin because the gap between the first claw portion 55 and the second claw portion 56 of the stop member 50 is narrow. However, by forming the base mounting portion 32 into an inverted T-shape, the strength of the base mounting portion 32 can be increased. As a result, the base mounting portion 32 can more stably support the base portion 54 of the stop member 50.

[0072] Furthermore, by having the base mounting portion 32 of this embodiment support the base portion 54 of the stop member 50 within the claw hole 31, the depth to which the first claw portion 55 and the second claw portion 56 of the stop member 50 enter the element guide passage can be limited. This prevents the first claw portion 55 and the second claw portion 56 of the stop member 50 from excessively entering the element guide passage, allowing the first claw portion 55 and the second claw portion 56 to properly engage with the zipper element 6. Furthermore, in the case of a zipper having a detachable insert having, for example, an insert rod, a seat rod, and a seat body, when the insert rod is inserted into the element guide passage of the slider body 10, the insert rod is less likely to be caught on the first claw portion 55 or the second claw portion 56, allowing the insert rod to be stably inserted into the seat body.

[0073] The pull-tab 40 of this embodiment includes a pull-tab main body 41 that is held by the user's fingers, left and right arm portions 42 extending from one end of the pull-tab main body 41, and a mounting shaft portion 43 that connects the top ends of the left and right arm portions 42. The cross-section of the mounting shaft portion 43 perpendicular to the axial direction has a circular shape or a shape close to a circular shape. The pull-tab 40 is provided with a rectangular opening window portion surrounded by the pull-tab main body 41, the left and right arm portions 42, and the mounting shaft portion 43. The mounting shaft portion 43 of the pull-tab 40 is held between the slider body 10 and the cover body 70. In addition, in the present invention, the shape, size, material, etc. of the pull-tab 40 are not particularly limited.

[0074] The stop member 50 is formed by a molded body obtained by injection molding a synthetic resin, and the stop member 50 is formed as a whole. The stop member 50 is formed of a synthetic resin having elasticity. In addition, in the present invention, the material of the stop member 50 is not particularly limited.

[0075] The stop member 50 includes a head 51 inserted between the left and right mounting walls 26 of the slider body 10, left and right rotation shafts 52 projecting outwardly from the head 51 in the left-right direction, a neck 53 extending rearward from the head 51, a base 54 connected to the rear end of the neck 53, claws 55 and 56 projecting downward from the bottom surface 54c of the base 54, and an elastically deformable elastic extension 58 extending from the head 51. Except for the claws 55 and 56, the stop member 50 has a bilaterally symmetrical shape with respect to its center position in the left-right direction.

[0076] The head 51 of the stopper 50 has a plate-like shape with a constant size in the left-right direction. The lower end of the head 51 is housed in the housing recess 28 of the slider body 10. The head 51 has a front end face 51a facing forward, a lower end face that continues from the lower end of the front end face 51a via a curved surface, and a pair of left and right side faces perpendicular to the left-right direction.

[0077] In the side view of the stop member 50 ( Figure 2 ), the front end surface 51a of the head 51 is formed into a curved surface that is slightly convexly curved forward. Alternatively, the front end surface 51a of the head 51 may be formed into a straight plane. The lower end surface of the head 51 is formed into a plane that faces downward and extends along the front-back direction. Each side surface of the head 51 is formed into a flat surface.

[0078] The width of the head 51 (the dimension in the left-right direction) is set smaller than the distance between the left and right mounting walls 26. In this embodiment, the width of the head 51 is set to be the same as the width of the portion of the front mounting post 21 above the step 25.

[0079] The rotation shaft portion 52 of the stop member 50 is formed in a cylindrical shape and is provided at the front end portion of the head portion 51. In a side view of the stop member 50, the frontmost surface (outer peripheral surface) or portion of the rotation shaft portion 52 is aligned with the front end surface 51a of the head portion 51.

[0080] Thus, for example, when the stop member 50 is lifted by bringing the mounting shaft portion 43 of the pull tab 40 into contact with the neck portion 53 of the stop member 50 from below, a wider gap can be maintained between the position of the rotating shaft portion 52 and the position where the mounting shaft portion 43 abuts the neck portion 53. Therefore, when the slider 1 is slid by pinching the pull tab 40, the stop member 50 can be lifted with less force to a position where the first claw portion 55 and the second claw portion 56 are clear of the element guide path. Furthermore, in the stop member 50 of the present invention, the rotating shaft portion 52 can be positioned at a substantially uniform position relative to the front end surface of the head portion 51, with a slight deviation in the front-to-back direction of, for example, within ±0.5 mm.

[0081] The neck portion 53 of the stop member 50 extends rearward from the head portion 51 and is formed so as to have a larger left-right dimension than the left-right dimension of the head portion 51. Figure 2 ), the neck 53 has a shape that is convexly curved toward the upper side.

[0082] The neck portion 53 has a concavely curved inner circumference, a convexly curved outer circumference, and flat left and right side surfaces. The left-right dimension of the neck portion 53 (the distance between the left and right side surfaces) is set to be larger than the distance between the left and right mounting walls 26 and smaller than the left-right dimension of the claw hole 31.

[0083] The rear end of the neck 53 is provided with a raised portion 53a that rises outward from the outer peripheral surface of the neck 53. The raised portion 53a is arranged in the left-right center of the neck 53. The provision of the raised portion 53a can improve the strength of the neck 53 and the base 54 of the stopper 50.

[0084] The base portion 54 of the stopper member 50 is inserted into the claw hole 31 of the slider body 10. When the first claw portion 55 and the second claw portion 56 of the stopper member 50 engage the zipper element 6, the base portion 54 of the stopper member 50 is placed on the base mounting portion 32 of the slider body 10. The base portion 54 has a connecting portion 54a connected to the rear end of the neck portion 53. The base portion 54 and the neck portion 53 are integrally formed via the connecting portion 54a. The base portion 54 has left and right flat side surfaces that are perpendicular to the left-right direction.

[0085] The base portion 54 is formed so that its left-right dimension (the distance between the left and right side surfaces) is set to a predetermined size larger than the left-right dimension of the neck portion 53. Furthermore, the left-right dimension of the base portion 54 is smaller than the left-right dimension of the claw hole 31. In particular, the base portion 54 of this embodiment is formed so that its left-right dimension is smaller than the maximum left-right dimension of the front mounting post 21 and the rear mounting post 22. Furthermore, the left-right dimension of the base portion 54 is set to be smaller than the left-right dimension between the outer side surfaces of the left and right rotation shaft portions 52 of the stop member 50.

[0086] By making the base portion 54 larger in the left-right direction than the neck portion 53, the left and right first claws 55 and second claws 56 can be provided separately from each other on the bottom surface 54c of the base portion 54. By making the left-right dimension of the base portion 54 smaller than the left-right dimension of the claw hole 31 and smaller than the left-right dimension between the outer side surfaces of the left and right rotation shaft portions 52, the position of the stop member 50 attached to the slider body 10 can be easily moved (adjusted) in the left-right direction relative to the slider body 10. This makes it easier for the first claw 55 and second claw 56 provided on the stop member 50 to engage with the left and right zipper elements 6, respectively.

[0087] The base portion 54 has a rear upper end surface 54b positioned rearward of the connecting portion 54a, an inner peripheral surface formed continuously from the inner peripheral surface of the neck portion 53, a rear end surface extending downward from the rear end of the rear upper end surface 54b via a bent portion, and a bottom surface 54c positioned perpendicular to the rear end surface. The rear upper end surface 54b, the rear end surface, and the bottom surface 54c of the base portion 54 are each formed as a flat surface.

[0088] The rear upper end surface 54b of the base portion 54 has a rotation limiting surface 54f, which is used to stop the slider 50 relative to the slider body 10 with the rotation axis 52 as the center in the direction in which the first claw portion 55 and the second claw portion 56 are separated from the chain element guide path (for example, Figure 5 When the stop member 50 is rotated (in the clockwise direction), the rotation restriction surface 54f abuts against an inner protrusion 73 of the cover body 70, which will be described later, to restrict the rotation of the stop member 50.

[0089] The rotation restriction surface 54f is, for example, Figure 6 As shown, the rotation-limiting surfaces 54f are provided on the left and right side edges of the rear upper end surface 54b of the base portion 54, corresponding to the locations of the inner protrusions 73 of the cover body 70. Providing such rotation-limiting surfaces 54f on the base portion 54 limits the rotation angle of the stop member 50, thereby preventing the elastic extension 58 of the stop member 50 from excessively deforming in a direction that narrows the gap between the neck portion 53 and the elastic extension 58 due to rotation of the stop member 50. This prevents the elastic force of the stop member 50 from weakening even if the stop member 50 repeatedly undergoes elastic deformation.

[0090] In this case, since the rotation restricting surface 54f is provided on the rear upper end surface 54b of the base portion 54, which ensures a large thickness of the base portion 54, the rotation restricting surface 54f of the base portion 54 can stably abut against the inner protrusion 73 of the cover body 70. In addition, even if the rotation restricting surface 54f of the stop member 50 repeatedly abuts against the inner protrusion 73 of the cover body 70, the stop member 50 is less likely to be damaged.

[0091] In the side view of the stop member 50 ( Figure 2 ), the inner circumference of the base portion 54 has a concave curved surface and an inclined surface that descends toward the front. The lower end of the inner circumference of the base portion 54 is arranged at a position forward of the boundary between the inner circumference of the neck portion 53 and the inner circumference of the base portion 54.

[0092] When the base portion 54 of the stopper member 50 is placed on the base mounting portion 32 of the slider body 10, the rear end face and bottom surface 54c of the base portion 54 are arranged in an orientation perpendicular to the front-to-back direction and perpendicular to the top-to-bottom direction, respectively. The rear end face and bottom surface 54c of the base portion 54 are each formed into a substantially rectangular shape. In this case, the front-to-back dimension of the bottom surface 54c of the base portion 54 is larger than the total front-to-back dimension of the first claw portion 55 or the second claw portion 56, as well as the front-to-back dimension of the claw reinforcement portion 57 (described later), and is smaller than the front-to-back dimension of the claw hole 31.

[0093] The bottom surface 54c of the base portion 54 is, for example, Figure 3 and Figure 4 As shown, the base portion 54 has a central flat surface 54d disposed in the front-to-back direction between the first claw portion 55 and the second claw portion 56, and a rear flat surface 54e disposed in the left-to-right direction at a position rearward of the first claw portion 55 and the second claw portion 56. When the base portion 54 is placed on the base mounting portion 32 of the slider body 10, the central flat surface 54d and the rear flat surface 54e of the base portion 54 are supported by direct contact with the longitudinal mounting portion 32a and the transverse mounting portion 32b of the base mounting portion 32, respectively.

[0094] The claws 55 and 56 of the stopper 50 include a first claw 55 provided at the front end of the bottom surface 54c of the base 54 in the front-to-back direction, and a second claw 56 provided at a position further rearward than the first claw 55. The first claw 55 protrudes downward from the bottom surface 54c of the base 54. The first claw 55 is provided at the right edge of the bottom surface 54c of the base 54 in the left-to-right direction.

[0095] The height dimension of the first claw portion 55 from the bottom surface 54c of the base portion 54 to the lower end of the claw of the first claw portion 55 is set to be larger than the diameter of the cross section of the monofilament forming the fastener element 6 and smaller than the vertical dimension of the flange portion 14 of the slider body 10. This allows the first claw portion 55 to be stably engaged with the fastener element 6 forming the element row 5.

[0096] When the first claw portion 55 is viewed from below with the stop member 50 mounted on the base mounting portion 32 of the slider body 10, the front-to-back dimension of the first claw portion 55 is set to be not less than 10% and not more than 40% of the front-to-back dimension of the bottom surface 54c of the base portion 54. The left-to-right dimension of the first claw portion 55 is set to be not less than 10% and not more than 40% of the left-to-right dimension of the bottom surface 54c of the base portion 54.

[0097] By setting the dimensions of the first claw 55 in the front-back direction and the left-right direction as described above, the strength of the first claw 55 can be appropriately ensured. In addition, when the first claw 55 is engaged with the fastener element 6, the first claw 55 can be smoothly inserted between the two fastener elements 6.

[0098] The first claw portion 55 is provided with a claw reinforcement portion 57 that extends rearward from the first claw portion 55 and is integrally formed with the base portion 54. The claw reinforcement portion 57 is formed so that the height dimension from the bottom surface 54c of the base portion 54 to the lower surface of the claw reinforcement portion 57 is less than or equal to 50% of the height dimension from the bottom surface 54c of the base portion 54 to the lower end of the claw of the first claw portion 55. This claw reinforcement portion 57 can improve the strength of the first claw portion 55.

[0099] The first claw portion 55 has a rearward inclined surface 55a inclined so that the left-right dimension of the first claw portion 55 gradually decreases toward the rear, and a downward inclined surface 55b inclined so that the left-right dimension of the first claw portion 55 gradually decreases toward the bottom.

[0100] The rear inclined surface 55a and the lower inclined surface 55b of the first claw portion 55 are respectively provided on the side surfaces of the left-right outer sides of the first claw portion 55. The rear inclined surface 55a is provided above the lower inclined surface 55b. The rear inclined surface 55a and the lower inclined surface 55b are adjacent to each other with a ridgeline (boundary) interposed therebetween.

[0101] The rear inclined surface 55a of the first claw 55 is formed at an angle of 45° relative to the front-to-back direction of the slider body 10. Providing the first claw 55 with such a rear inclined surface 55a ensures the appropriate strength of the first claw 55. Furthermore, as will be described later, when the first claw 55 is engaged with the fastener elements 6 of the right element row 5, the first claw 55 is less likely to interfere with the sewing portion 7 of the sewing line of the fastener elements 6. Therefore, the first claw 55 can be smoothly inserted between the front and rear adjacent fastener elements 6 of the right element row 5, allowing it to be stably engaged with the fastener elements 6.

[0102] The lower inclined surface 55b of the first claw 55 is formed at an angle of 45° relative to the vertical direction of the slider body 10. Providing such a lower inclined surface 55b on the first claw 55 prevents the insertion rod of the right-insertion release insert from interfering with the first claw 55 of the stop member 50, preventing the release insert from being inserted into the slider body 10. This prevents the first claw 55 from reducing the operability of the release insert.

[0103] The second claw 56 of the stopper 50 protrudes downward from the bottom surface 54c of the base 54. The second claw 56 is located at a position spaced apart from the front edge of the base 54 and also spaced apart from the rear edge of the base 54 in the front-to-back direction. In this embodiment, the second claw 56 is located near the front of the base 54 so that the distance from the front edge of the base 54 to the second claw 56 is shorter than the distance from the rear edge of the base 54 to the second claw 56 in the front-to-back direction. The second claw 56 is located at the left edge of the bottom surface 54c of the base 54 in the left-to-right direction.

[0104] The height dimension of the second claw portion 56 from the bottom surface 54 c of the base portion 54 to the lower end of the claw portion 56 is set to be larger than the diameter of the cross section of the monofilament forming the fastener element 6 and smaller than the vertical dimension of the flange portion 14 of the slider body 10 .

[0105] Furthermore, in this embodiment, the height dimension of the second claw 56 is set smaller than the height dimension of the first claw 55 , and the lower end of the first claw 55 is arranged farther from the bottom surface 54 c of the base 54 than the lower end of the second claw 56 .

[0106] Here, in the slider 1 of this embodiment, if the positions of the first claw 55 and the second claw 56 of the stop member 50 when entering the element guide path of the slider body 10 are compared, for example, Figure 7 As shown, the first claw portion 55 enters the element guide passage at a position rearward of the coupling post 13 and forward of the second claw portion 56 in the front-rear direction.

[0107] On the other hand, in the area behind the connecting post 13 of the left and right fastener element rows 5 that pass through the fastener element guide passage of the slider body 10 and before the left and right fastener elements 6 are engaged, the spiral fastener elements 6 are bent so as to temporarily expand the interval between the front and rear adjacent fastener elements 6. In this case, the interval between the front and rear adjacent fastener elements 6 is expanded at the position where the first claw portion 55 enters the fastener element guide passage of the slider body 10 compared to the position where the second claw portion 56 enters the fastener element guide passage of the slider body 10.

[0108] Therefore, in the slider 1 of this embodiment, the first claw 55, which has a larger height dimension than the second claw 56, can be inserted deeper between the fastener elements 6 than the second claw 56 at a position where it is closer to the connecting post 13 than the second claw 56 and the intervals between the fastener elements 6 are larger. In addition, the second claw 56 can be inserted shallower between the fastener elements 6 than the first claw 55 at a position where it is farther from the connecting post 13 than the first claw 55 and the intervals between the front and rear adjacent fastener elements 6 are smaller than those of the first claw 55.

[0109] Thus, in this embodiment, by making the height dimension of the first claw portion 55 larger than the height dimension of the second claw portion 56, the first claw portion 55 and the second claw portion 56 can be respectively inserted to an appropriate depth corresponding to the interval between the front and rear adjacent fastener elements 6, thereby stably engaging with the fastener elements 6. In addition, in the present invention, the first claw portion 55 and the second claw portion 56 may have the same height dimension.

[0110] In this embodiment, the dimension of the second claw portion 56 in the front-to-back direction is set to be not less than 10% and not more than 40% of the dimension of the bottom surface 54 c of the base portion 54 in the front-to-back direction, similarly to the case of the first claw portion 55. The dimension of the second claw portion 56 in the left-to-right direction is also set to be not less than 10% and not more than 40% of the dimension of the bottom surface 54 c of the base portion 54 in the left-to-right direction, similarly to the case of the first claw portion 55.

[0111] To enhance the strength of the second claw portion 56, a claw reinforcement portion 57 is provided on the second claw portion 56. The claw reinforcement portion 57 extends forward from the second claw portion 56 and is integrally formed with the base portion 54. The claw reinforcement portion 57 is formed so that the height from the bottom surface 54c of the base portion 54 to the lower surface of the claw reinforcement portion 57 is less than or equal to 50% of the height of the second claw portion 56.

[0112] Similar to the first claw portion 55, the second claw portion 56 has a rear inclined surface 56a that is inclined so that the left-right dimension of the second claw portion 56 gradually decreases toward the rear, and a lower inclined surface 56b that is inclined so that the left-right dimension of the second claw portion 56 gradually decreases toward the bottom. The rear inclined surface 56a and the lower inclined surface 56b of the second claw portion 56 are respectively provided on the left-right outer side surface of the second claw portion 56. The rear inclined surface 56a is provided above the lower inclined surface 56b.

[0113] Providing the rear inclined surface 56 a on the second claw portion 56 can appropriately ensure the strength of the second claw portion 56 and can also make it difficult for the second claw portion 56 to interfere with the sewing portion 7 of the sewing line of the fastener element 6 .

[0114] By providing the second claw portion 56 with a lower inclined surface 56b, for example, when the zipper is provided with a left-inserted opening insert, the insertion rod of the opening insert can be prevented from interfering with the second claw portion 56 of the stopping member 50 and failing to be inserted into the slider body 10.

[0115] In the stop member 50 of this embodiment, the left-right distance between the first claw portion 55 and the second claw portion 56 (in other words, the left-right dimension of the central flat surface 54d of the base portion 54) is set to be smaller than the left-right dimension of the head portion 51 of the stop member 50. Thus, when the first claw portion 55 and the second claw portion 56 of the stop member 50 are inserted into the element guide passage of the slider body 10, the first claw portion 55 and the second claw portion 56 can be stably engaged with the fastener element 6 at a position further inward than the sewing portion 7 where the fastener element 6 is sewn to the fastener tape.

[0116] The elastic extension 58 of the stop member 50 applies force in the rotational direction of the stop member 50, causing the first claw 55 and the second claw 56 to enter the element guide passage. The elastic extension 58 includes a deformed base end 58a connected to the upper end of the head 51 and an elastic piece 58b extending obliquely upward and rearward from the deformed base end 58a. The deformed base end 58a and the elastic piece 58b each have a left-right dimension that is the same as the left-right dimension of the head 51.

[0117] The deformed base end portion 58a of the elastic extension portion 58 is formed so as to extend upward from the head portion 51 so that the dimension of the deformed base end portion 58a in the front-to-back direction gradually decreases and bends toward the rear. The front surface of the deformed base end portion 58a faces forward and is formed in a side view of the stop member 50 ( Figure 2 ) is formed into a curved surface that is curved in an arc shape or a convex shape. The front surface of the deformed base end portion 58a is not provided with a step or a concave-convexity between the front surface 51a of the head portion 51, but is smoothly continuous with the front surface 51a of the head portion 51.

[0118] The elastic piece 58b of the elastic extension 58 has a flat first surface (outer surface) and a flat second surface (inner surface) located opposite the first surface. The elastic piece 58b has an elongated plate-like shape with a constant or substantially constant thickness between the first and second surfaces. When the slider 1 is assembled, the top end (upper end) of the elastic piece 58b contacts the inner surface of the top plate portion 71a of the cover 70, which will be described later.

[0119] In the side view of the stop member 50 ( Figure 2), the elastic piece 58b extends straight from the deformed base end 58a toward the upper and rearward direction. The elastic piece 58b is formed to be inclined at an angle θ of not less than 10° and not more than 40° relative to the front-to-back direction. The elastic piece 58b, the head 51, and the neck 53 are formed so that the vertical dimension of the space formed between them gradually increases toward the rear.

[0120] When the stop member 50 rotates around the rotation shaft portion 52 in the direction in which the first claw portion 55 and the second claw portion 56 are separated from the chain tooth guide path, the elastic sheet portion 58b is elastically deformed into a curved shape in a manner that narrows the space between the elastic sheet portion 58b and the head portion 51 and the neck portion 53, and the elastic sheet portion 58b can apply a stronger force to the stop member 50 in the direction in which the first claw portion 55 and the second claw portion 56 enter the chain tooth guide path (for example, refer to Figure 8 ).

[0121] The stop member 50 of this embodiment has an axially opposed inner peripheral surface 59. In the side view of the stop member 50 ( Figure 2 ), when the slider 1 is assembled, the shaft-relative inner circumferential surface 59 is configured to surround the mounting shaft portion 43 of the pull-tab 40. The shaft-relative inner circumferential surface 59 of the stop member 50 is formed by the inner circumferential surface of the head 51, the inner circumferential surface of the neck 53, and the inner circumferential surface of the base 54, so as to span the continuous inner circumference of the head 51, the neck 53, and the base 54. Inside the shaft-relative inner circumferential surface 59, a storage space 50a for storing the mounting shaft portion 43 of the pull-tab 40 is formed in a shape that is, for example, recessed obliquely toward the rear and upper side.

[0122] Here, in the side view of the stop member 50 in the state (orientation) in which the stop member 50 of the present embodiment is placed on the base placement portion 32 of the slider body 10, the position of the portion of the stop member 50 disposed at the rearmost position relative to the inner peripheral surface 59 of the shaft is as shown in FIG. Figure 2 As shown, it is virtually defined as the reference position 60 . In this case, the first claw 55 of the stopper 50 is provided at a position forward of the reference position 60 , and the second claw 56 is provided so as to overlap with the reference position 60 .

[0123] By providing the first claw portion 55 and the second claw portion 56 of the stop member 50 relative to the reference position 60 as described above, for example, Figure 7 As shown, the first claw 55 and the second claw 56 enter the element guide passage of the slider body 10 in a range behind the connecting post 13 in the element guide passage of the slider body 10 and at a position closer to the connecting post 13 .

[0124] In this element guide passage, the left and right zipper elements 6 are not engaged at positions near the connecting post 13. Furthermore, to allow the left and right zipper elements 6 to engage at a position forward of the parallel portions of the left and right flanges 14 (the straight portions 14a described later), the spacing between adjacent zipper elements 6 in the front-to-back direction is easily increased. Consequently, the first and second claws 55, 56 of the stopper member 50, which has entered the element guide passage, can smoothly engage with the zipper elements 6.

[0125] Here, the left and right flange portions 14 of the slider 1 include: a straight portion 14a, in which the inner wall surfaces of the left and right flange portions 14 are parallel; and a turning portion 14b, in which the inner wall surface of the flange portion 14 is bent toward the outside in the left and right directions from the front end portion of the straight portion 14a so that the interval between the left and right flange portions 14 gradually increases toward the front.

[0126] In this case, the first claw 55 and the second claw 56 of the stopping member 50 are located forward of the boundary 14c between the straight portion 14a and the turning portion 14b of the flange portion 14 in the front-to-rear direction relative to the slider body 10, and are located rearward of the front end of the flange portion 14 (the front end of the turning portion 14b).

[0127] Furthermore, in this embodiment, by arranging the first claw 55 and the second claw 56 of the stop member 50 relative to the reference position 60 as described above, the first claw 55 and the second claw 56 can be positioned closer to the rotation shaft 52 of the stop member 50 .

[0128] For example, in the stopping member 50 of the present embodiment, the stopping member 50 is rotated upward around the rotating shaft portion 52 from a state in which the first claw portion 55 and the second claw portion 56 are engaged with the zipper chain element 6, thereby releasing the engagement state of both the first claw portion 55 and the second claw portion 56 with the zipper chain element 6.

[0129] In this case, compared with the case where the first claw portion and the second claw portion of the stop member are provided at positions further back than the above-mentioned reference position (comparative example), in the stop member 50 of this embodiment, it is possible to ensure that the stop member 50 is engaged with the first rotation position (for example, the first rotation position) of the zipper element 6 from the first claw portion 55 and the second claw portion 56. Figure 5 The stop member 50 is rotated to the second rotation position (eg, Figure 8 The rotation angle and rotation amount of the stop member 50 when the position of the stop member 50 is shown).

[0130] That is, in the slider 1 having the stopping member 50 of this embodiment, compared with the case of the above-mentioned comparative example, during the period when the stopping member 50 rotates from the first rotation position to a larger rotation amount, the engagement state of both the first claw 55 and the second claw 56 with the zipper chain element 6 can be maintained, thereby exerting the stopping function of the stopping member 50.

[0131] like Figure 1 and Figure 8 As shown, the cover body 70 includes a box-shaped cover body 71 with an opening at the bottom, and front and rear engaging protrusions 72 and left and right inner protrusions 73 provided inside the cover body 71. The cover body 71 includes a top plate 71a that is long in the front-to-back direction, a front wall 71b that curves downward from the front end of the top plate 71a, a rear wall 71c that curves downward from the rear end of the top plate 71a, and left and right side walls that extend downward from the left and right side edges of the top plate 71a.

[0132] The top plate portion 71a of the cover body 71 is convexly curved upward relative to the front-to-back direction. The front wall portion 71b and rear wall portion 71c of the cover body 71 are formed continuously from the top plate portion 71a. The front wall portion 71b of the cover body 71 has a smooth front end facing forward, while the rear wall portion 71c has a smooth rear end facing rearward.

[0133] The left and right side walls of the cover body 71 are connected to the top plate 71a, front wall 71b, and rear wall 71c via curved portions, respectively. An insertion opening 74 is provided in the front-to-back center of the side walls of the cover body 71, into which the mounting shaft 43 of the pull-tab 40 is inserted. The insertion opening 74 of the cover body 71 extends upward from the lower end of the side walls.

[0134] The engaging protrusions 72 of the cover body 70 protrude from the inner wall surfaces of the front wall portion 71b and the rear wall portion 71c of the cover body 71 toward the inner side in the front-back direction. Figure 8 ) is formed into a triangular shape having an upper end surface locked with the engaging claw portion 24 and an inclined surface inclined relative to the up and down direction in a manner that can engage with the engaging claw portion 24 of the front side mounting column 21 of the slider body 10 and the engaging claw portion 24 of the rear side mounting column 22.

[0135] If the cover 70 is made of synthetic resin and has such front and rear engaging protrusions 72, for example, when the cover 70 is mounted on the slider body 10, the cover 70 can be covered from above by slightly elastically deforming at least one of the cover 70, the front mounting post 21, and the rear mounting post 22, so that the front and rear engaging protrusions 72 of the cover 70 can be hooked and engaged with the engaging claws 24 provided on the front mounting post 21 and the rear mounting post 22 of the slider body 10. Thus, the cover 70 can be easily mounted on the front mounting post 21 and the rear mounting post 22 of the slider body 10 by snap-fit ​​engagement.

[0136] The left and right inner protrusions 73 of the cover body 70 protrude inward in the left and right directions from the left and right side walls of the cover body 71. Furthermore, the left and right inner protrusions 73 are connected to the top plate 71a of the cover body 71. Each of the left and right inner protrusions 73 includes a front protrusion 73a extending rearward from the front wall 71b of the cover body 71, and a rear protrusion 73b extending forward from the rear wall 71c of the cover body 71.

[0137] The left and right front protrusions 73a are arranged to contact or approach the upper surfaces of the step 25 and mounting wall 26 provided on the front mounting post 21 of the slider body 10 from above. By placing the front protrusions 73a in contact with or close to the upper surfaces of the mounting wall 26, the insertion recess 26a provided in the mounting wall 26 can be closed from above, forming a cover. This prevents the rotation shaft 52 of the stop member 50, held within the insertion recess 26a of the mounting wall 26, from being dislodged.

[0138] The left and right rear protrusions 73b are configured to contact the step portion 25 provided on the rear mounting post 22 of the slider body 10 from the upper side, or to be configured to be close to the step portion 25 provided on the rear mounting post 22 of the slider body 10 from the upper side. In addition, the rear protrusion 73b is configured so that when the stop member 50 is rotated in the direction in which the first claw portion 55 and the second claw portion 56 are separated from the chain element guide path, the rear protrusion 73b abuts against a part of the rear upper end surface 54b of the base portion 54 (the rotation limiting surface 54f).

[0139] Next, a method for manufacturing the slider 1 of the present embodiment by assembling the four components of the slider body 10 , the pull tab 40 , the stopper 50 , and the cover 70 will be described.

[0140] First, the pull tab 40 is placed on the upper wing plate 11 of the slider body 10. At this time, the mounting shaft portion 43 of the pull tab 40 is inserted between the mounting wall portion 26 and the pull tab guide portion 27 of the slider body 10, and the front mounting post 21 or the rear mounting post 22 is inserted into the opening window portion of the pull tab 40.

[0141] Next, the stopper member 50 is placed on the slider body 10 with the pull tab 40 placed thereon. At this point, the lower end of the head portion 51 of the stopper member 50 is inserted into the receiving recess 28 provided in the upper wing plate 11 of the slider body 10. Furthermore, the base portion 54, first claw portion 55, and second claw portion 56 of the stopper member 50 are inserted into the claw hole 31 of the slider body 10, and the base portion 54 is placed on the base receiving portion 32 provided in the claw hole 31.

[0142] Afterwards, the cover 70 is mounted on the slider body 10 on which the pull tab 40 and the stop member 50 are mounted. At this point, the cover 70 is positioned close to the slider body 10, with the front (or rear) side of the cover 70 tilted downward, so that the cover 70 covers the mounting shaft 43 of the pull tab 40 and the stop member 50 from above. Furthermore, the front (or rear) side engaging protrusion 72 of the cover 70 is hooked onto the engaging claw 24 provided on the front mounting post 21 (or rear mounting post 22) of the slider body 10.

[0143] Then, the rear end (or front end) of the cover body 70 is pressed downward so that the inclined cover body 70 is along the front-back direction. Thus, the cover body 70 can be easily mounted on the front mounting post 21 and the rear mounting post 22 of the slider body 10 in a snap-fit ​​manner.

[0144] The slider 1 of this embodiment is manufactured by performing such an assembly process. The slider 1 can be assembled easily and stably by manually or using an automatic assembly machine, in which the cover 70 is attached to the slider body 10 by the aforementioned snap engagement.

[0145] Furthermore, by attaching the cover 70 to the slider body 10, the elastic extension 58 of the stop member 50 is pressed by the cover 70 and elastically deformed. This elastic deformation of the elastic extension 58 applies an elastic force to the stop member 50 in a direction that causes the first claw 55 and the second claw 56 to enter the element guide passage of the slider body 10.

[0146] In the slider 1 of this embodiment manufactured as described above, all four components, namely, the slider body 10 , the handle 40 , the stopper 50 , and the cover 70 , can be formed of synthetic resin.

[0147] In addition, in the slider 1 of the present embodiment, when the slider 1 is not in operation and the pull tab 40 is in a free state, the first claw 55 and the second claw 56 can enter the chain tooth guide passage of the slider body 10 and engage with the zipper chain tooth 6 under the action of the elastic force (force) of the elastic extension portion 58 of the stopping member 50.

[0148] Therefore, when forming a slide fastener using the slider 1 of this embodiment, the slider 1 can include a stopping mechanism using the stopping member 50 that automatically locks the slider 1 at a stopped position relative to the element rows 5 so as not to move the slider 1 .

[0149] In the slider 1 of this embodiment, Figure 2 As shown, the first claw 55 of the stop member 50 is provided at a position forward of the reference position 60 of the stop member 50, and the second claw 56 is provided to overlap with the reference position 60. Thus, when the first claw 55 and the second claw 56 of the stop member 50 are inserted into the element guide passage of the slider body 10, as described above, the first claw 55 and the second claw 56 can be respectively inserted into the portion where the interval between the fastener elements 6 is enlarged in the left and right element rows 5 (see FIG. Figure 7 ). Therefore, the first claw portion 55 and the second claw portion 56 of the stopping member 50 can be stably engaged with the fastener element 6, respectively.

[0150] In particular, in this embodiment, rear inclined surfaces 55a and 56a are provided on the first claw 55 and the second claw 56, respectively. Therefore, when the first claw 55 and the second claw 56 are engaged with the zipper element 6, the first claw 55 and the second claw 56 are less likely to interfere with the sewing portion 7 of the sewing line formed on the element row 5. Consequently, the first claw 55 and the second claw 56 can be engaged with the zipper element 6 more smoothly.

[0151] Furthermore, by setting the first claw 55 and the second claw 56 of the stopping member 50 relative to the reference position 60 as described above, the rotation angle (rotation amount) of the stopping member 50 from the first rotation position in which the base portion 54 of the stopping member 50 is placed on the base placement portion 32 and the first claw 55 and the second claw 56 are engaged with the zipper chain element 6 to the second rotation position in which the engagement of the first claw 55 and the second claw 56 with the zipper chain element 6 is released can be ensured to a greater extent than in the comparative example in which, for example, the first claw and the second claw are placed at a position rearward of the reference position with the same size.

[0152] Therefore, in the slider 1 of the present embodiment, for example, when the slider 1 of the zipper is not in operation, even if the stopping member 50 rotates at a smaller rotation angle due to the swinging of the pull tab 40, the engagement state of both the first claw 55 and the second claw 56 with the zipper chain element 6 can be maintained, and the stopping function of the stopping member 50 can be stably exerted.

[0153] On the other hand, when the slider 1 is slid along the element row 5, for example, the user pinches the pull tab 40 and pulls it in the direction in which the slider 1 is slid. Figure 8 As shown, by means of the mounting shaft portion 43 ( Figure 8 (not shown) the stopping member 50 overcomes the elastic force of the elastic extension 58 and rotates in a direction in which the first claw 55 and the second claw 56 are separated from the element guide path. As a result, the stopping function of the stopping member 50 of the slider 1 is released, so that the slider 1 can slide freely along the element row 5.

[0154] In addition, the present invention is not limited to the above-mentioned embodiment at all, and various modifications can be made as long as the configuration is substantially the same as that of the present invention and the same functions and effects are achieved.

[0155] For example, the stop member 50 of the above embodiment is provided with two claws 55 and 56, namely the first claw 55 and the second claw 56. However, the stop member of the present invention may be provided with only one claw protruding from the left or right edge of the bottom surface of the base portion and arranged forward of the above reference position.

[0156] Furthermore, in the stopper member 50 of the above embodiment, the first claw portion 55 is arranged forward of the second claw portion 56, and the front first claw portion 55 is arranged at the right edge of the bottom surface 54c of the base portion 54. The rear second claw portion 56 is arranged at the left edge of the bottom surface 54c of the base portion 54. However, in the present invention, the front first claw portion may be arranged at the left edge of the bottom surface of the base portion, and the rear second claw portion may be arranged at the right edge of the bottom surface of the base portion.
