[0007] Patent Document 1: International Publication No. 2018 / 142548 Utility Model Content

[0008] In the zipper product described in Patent Document 1, the gap formed between the fixing member and the tooth mounting edge of the fabric can be made smaller by deepening the recess, thereby improving the appearance. On the other hand, when a pair of meshing tooth members are bent along the length direction, sometimes the main body of the adjacent tooth enters the recess formed in the main body of the tooth, resulting in chain separation in which the meshing of the tooth is released. Therefore, it is desired to prevent the occurrence of chain separation even when the tooth is formed with a recess into which a part of the tooth mounting edge of the fabric is inserted.

[0009] The utility model is made in view of the above-mentioned problems, and its object is to provide a chain component for a slide fastener and a product with a slide fastener, which can prevent the chain separation that causes the disengagement of the elements when a pair of meshing element rows are bent along the length direction.

[0010] The above-mentioned object of the present invention is achieved by the following structure.

[0011] [1] A zipper chain component, comprising a pair of left and right zipper element components (10), wherein the zipper element components (10) include a linear fixing component (15) extending in a longitudinal direction, and a plurality of elements (40) mounted on the fixing component (15) and forming an element row (11), wherein:

[0012] The pair of left and right slide fastener element components (10, 10) can mesh with each other.

[0013] The above-mentioned fastener element (40) comprises: an engaging portion (42) which engages with the above-mentioned fastener element (40) on the opposite side of the engagement; and a main body (41) which extends from the above-mentioned engaging portion (42) in the left-right direction and is fixed to the above-mentioned fixing member (15).

[0014] In the main body (41), a recess (45) is provided along the longitudinal direction on the anti-engaging portion side located on the opposite side of the engaging portion (42) relative to the fixing member (15).

[0015] When the left and right pair of zipper tooth components (10, 10) are meshed, when the left and right pair of zipper tooth components (10, 10) are bent along the length direction in the direction in which the surfaces or backs of the tooth components (40) are relative to each other, when the main bodies (41) of the adjacent tooth components (40) of the zipper tooth components (10) are in contact with each other, the meshing parts (42) of the adjacent tooth components (40) of the left and right pair of zipper tooth components (10, 10) are not in contact with each other.

[0016] [2] A product with a zipper, comprising:

[0017] [1] The chain component for a slide fastener;

[0018] A slider (30) for engaging the pair of left and right slide fastener element components (10, 10); and

[0019] A zipper installation component (7, 7) is used to install the above-mentioned pair of left and right zipper element components (10, 10).

[0020] Utility Model Effect

[0021] According to the present invention, when a pair of meshing element rows are bent in the longitudinal direction, disengagement of the elements can be prevented by bringing the main bodies of the elements adjacent in the longitudinal direction into contact with each other on the same element member.

[0084] Hereinafter, the chain member for slide fasteners and the product with slide fasteners which concern on embodiment of this invention are demonstrated in detail based on drawings.

[0085] In addition, in this specification, "up and down direction" refers to the sliding direction of the slider, and refers to the length direction of the chain tooth component and the width direction of the chain tooth. In particular, the direction in which the slider slides so that a pair of left and right chain tooth rows are meshed is set to "upward", and the direction in which the slider slides so that the left and right chain tooth rows are separated is set to "downward".

[0086] In addition, the "left-right direction" refers to the direction in which a pair of chain teeth are arranged, and refers to the direction orthogonal to the sliding direction of the slider. It can be renamed the front-to-back direction of the chain teeth, with the direction of the chain teeth toward the opposite side of the meshing being set as the "front" and the opposite side being set as the "rear".

[0087] Furthermore, the “back-to-front direction” refers to a direction perpendicular to the up-down direction and the left-right direction, and may also be referred to as the height direction of the fastener element. In addition, a pair of components may be described as “left-right” components based on the drawings.

[0088] based on Figure 1 to Figure 3 The structure of the product 1 with a slide fastener to which the present invention is applied will be described. Figure 1 It is a top view schematically showing the main part of the product with a slide fastener according to one embodiment of the present invention. Figure 2 It is enlarged from the back side Figure 1 The product with a zipper is shown in a bottom view schematically showing the main parts. Figure 3 It is a product with a zipper along Figure 1 Cross-sectional view along line AA. Figure 4 It is a plan view of the main parts showing the meshing state of a pair of fastener element members.

[0089] The product 1 with a zipper in this embodiment is a garment (clothing product) with a zipper, and a front piece of a front piece of the product 1 with a zipper is formed. Figure 1 Such a zipper 5 is shown.

[0090] In addition, left and right element attachment edges 7 for attaching left and right element components 10 described later are provided on left and right fabrics 6 forming a front piece (especially, a front piece) serving as an opening and closing portion in the slide fastener product 1.

[0091] In this case, the fabric 6 (also referred to as clothing fabric) constituting the front sheet of the product with a zipper 1 becomes a zipper mounting member to which the element member 10 is mounted. Figure 1 As shown, the slide fastener 5 formed in this embodiment includes: a pair of left and right element members 10 directly fixed to the surface material 6 and forming the element rows 11; and a slider 30 capable of engaging and disengaging the left and right element rows 11.

[0092] In the present embodiment, the thickness, shape, flexibility and other properties of the fabric 6 that serves as the zipper attachment member are not particularly limited, but the fabric 6 is preferably formed so that a sewing machine needle can penetrate it during sewing with a sewing machine.

[0093] In the present embodiment, the link tooth mounting edge 7 provided on the fabric 6 has a prescribed size in the width direction of the link tooth component 10 from the relative side edges of the fabric 6 constituting the left and right front pieces toward the inner side of the fabric 6 in the completed zipper product 1, and is continuously formed along the length direction of the link tooth component 10.

[0094] In the case of the present embodiment, the element attachment edge 7 is a portion including at least the range from the above-mentioned opposite side edge to the top end of the folded-back side attachment edge 9 in the width direction. Figure 2 .

[0095] For example Figure 3As shown, each of the left and right element mounting edges 7 is formed by folding the side edge portion of the cut end portion of the fabric 6 back to the back side into a U shape. In this way, by forming the element mounting edge 7, the element mounting edge 7 is partially formed thicker than other portions of the thin fabric 6, and the strength of the element mounting edge 7 can be improved.

[0096] Thus, even if the sewing thread 21 (the upper thread 21a and the lower thread 21b described later) of the fixing sewing portion 20 pierces the element mounting edge 7 as described later, the element mounting edge 7 is difficult to be cut by the sewing thread 21, and the durability of the element mounting edge 7 can be improved. In addition, by improving the strength of the element mounting edge 7, the element component 10 can be firmly fixed to the element mounting edge 7, and the position and posture of each zipper element (hereinafter also referred to as element) 40 fixed to the element mounting edge 7 can be stabilized.

[0097] Moreover, by folding the side edge of the fabric 6 back into a U-shape, even if a fraying occurs at the side edge of the fabric 6, the fraying can be hidden on the back side of the element mounting edge 7 and not exposed to the outside. Thus, the garment 1 can have a good appearance quality (beautiful). In addition, it is possible to prevent the meshing of the left and right element rows 11 from being deteriorated and the sliding property (smoothness of sliding) of the slider 30 from being reduced due to the fraying generated at the side edge of the fabric 6.

[0098] Moreover, in the present embodiment, a reinforcing sheet member such as a resin film (not shown) can be attached and installed or sewn together with the fastener element member 10, for example, on at least one of the surface and the back of the fastener element mounting edge 7, and / or on the inner side (between the upper and lower folded parts) of the side edge folded back into a U shape of the fastener element mounting edge 7. Thus, the fastener element mounting edge 7 can also be reinforced. In addition, in the present invention, the structure of the fabric of the clothing is not particularly limited and can be appropriately changed according to the purpose of the clothing.

[0099] like Figure 1 As shown, the slider 30 of this embodiment attached to the element row 11 includes a slider body 31 and a pull tab 32 held by the slider body 31. The slider body 31 of this embodiment has substantially the same structure as a conventional slider body generally used for injection-molded fastener elements 40.

[0100] That is, Figure 3 As shown, the slider body 31 of the present embodiment comprises: an upper wing plate 33; a lower wing plate 34, which is separated from the upper wing plate 33 and arranged in parallel with the upper wing plate 33; a connecting column (not shown), which connects the front end portion of the upper wing plate 33 and the front end portion (shoulder side end portion) of the lower wing plate 34; upper and lower flange portions 36, 37, which are arranged on the left and right side edges of the upper wing plate 33 and the left and right side edges of the lower wing plate 34; and a pull tab mounting portion 38, which is arranged on the upper surface of the upper wing plate 33 and is used to hold the pull tab 32.

[0101] In addition, left and right shoulder openings are formed at the front end of the slider body 31 in a manner of sandwiching the connecting column, and a rear opening is formed at the rear end of the slider body 31. A substantially Y-shaped fastener guide path is formed between the upper wing plate 33 and the lower wing plate 34 to connect the left and right shoulder openings and the rear opening. By using the slider 30 having such a structure, the left and right fastener components 10 directly fixed to the fastener mounting edge 7 of the clothing 1 can be smoothly engaged and separated.

[0102] Next, based on Figures 5 to 9 The specific structure of the slide fastener element component 10 will be described in detail. Figure 5 Yes means Figure 1 A perspective view of a fastener element mounted to a fixing member used in a product with a zipper is shown. Figure 6 yes Figure 5 A top view of the chain element is shown. Figure 7 yes Figure 5 Rear view of the chain element shown. Figure 8 yes Figure 5 Right side view of the chain element shown. Fig. 9 yes Figure 5 Bottom view of the chain element shown.

[0103] The fastener element component for a slide fastener (hereinafter, also simply referred to as the fastener element component) 10 in the present embodiment includes a linear fixing member 15 and a plurality of independent fastener elements 40 attached to the fixing member 15 .

[0104] The fixing member 15 is in the shape of a single line. A plurality of independent fastener elements 40 are attached to the fixing member 15 at regular intervals in the width direction of the fastener elements 40 to form the fastener element row 11 .

[0105] A pair (two) of the element components 10 is regarded as a set, and the pair of left and right element components 10 and 10 is also referred to as a slide fastener chain component. Figure 1 The left and right element components 10 are sewn along the end portions of the left and right element attachment edges 7 provided on the product 1 with a slide fastener.

[0106] The fixing member 15 is a rope body (also called a knit cord) formed by wrapping a core wire composed of multiple parallel multifilaments in a bag woven by multiple braiding wires, and has flexibility. In addition, the fixing member 15 used in the utility model is not particularly limited as long as it can be equipped with multiple chain elements 40, and can also be formed by, for example, a monofilament or a twisted wire (twisted rope).

[0107] The fixing member 15 is a member having a substantially circular cross section perpendicular to the longitudinal direction. Figure 3As shown, the fixing member has a flat cross-sectional shape by deformation in the fastener element 40. However, in the present invention, the cross-sectional shape of the fixing member is not particularly limited.

[0108] Each fastener element 40 of the fastener element member 10 is formed integrally with the fixing member 15 by injection molding a thermoplastic resin such as polyacetal resin into the fixing member 15 , for example, and is formed so as to cover the entire outer peripheral surface of a part of the fixing member 15 .

[0109] In addition, in the present invention, the material of the fastener element 40 is not limited to the synthetic resin mentioned above, and the fastener element can also be formed by, for example, other synthetic resins or metals. In addition, the fastener element component 10 of the present invention is not limited to the fastener element 40 formed on the fixing component 15 by injection molding, and for example, it also includes a fastener element component formed by fixing the fastener element 40 pre-formed into a predetermined shape to the fixing component 15 by welding or bonding.

[0110] Also like Figure 5 As shown, each link tooth 40 of the present embodiment comprises: an engaging portion 42, which engages with the link tooth 40 of the link tooth component 10 on the opposite side of the engagement; and a main body portion 41, which extends from the engaging portion 42 toward the front-to-back direction of the link tooth 40 (a direction orthogonal to the extension direction of the fixing component 15 when viewed from above) and is fixed to the fixing component 15.

[0111] Each fastener element 40 of the present embodiment has an element front half 43 and an element back half 44 which are distinguished based on a substantially middle position in the height direction of the fastener element 40 (in the present embodiment, the center position of the fixing member 15 in the height direction of the fastener element 40).

[0112] In this case, the surface of the element front half portion 43 and the element back half portion 44 are arranged to be perpendicular to the height direction of the element 40 and parallel to each other.

[0113] At the rear end portion of the fastener element 40 , a recessed portion 45 extending in the width direction of the fastener element 40 is formed between the fastener element front half portion 43 and the fastener element back half portion 44 .

[0114] Moreover, the meshing portion 42 of each fastener element 40 has a deformed portion 43 b on the fastener element front half portion 43 side and locking portions 44 b and 44 c on the fastener element back half portion 44 side.

[0115] The front half of the chain tooth 43 comprises: a front side engaging head (special-shaped portion) 43b, which engages with the chain tooth on the opposite side of the engaging portion to form the front half of the engaging portion 42; and a front side main body portion 43a, which extends from the front side engaging head 43b toward the rear of the chain tooth component 10 and clamps the fixing component between the front side main body portion 43a and the chain tooth back half 44.

[0116] The front engaging head 43b has a pair of decreasing portions 46 in a shape in which the element width gradually decreases toward the tip of the front engaging head 43b and is formed on the side surface of the front engaging head 43b.

[0117] In addition, if Figure 5 As shown, the side surfaces (upper and lower surfaces) of the front side engaging head 43b (decreasing portion 46) are provided with head side inclined surfaces 46a which gradually decrease the width of the elements toward the element surfaces. The head side inclined surfaces 46a may also be provided as R-shaped curved surfaces on the side surfaces of the elements of the front side engaging head 43b.

[0118] The front side main body 43a is formed into a substantially rectangular parallelepiped shape that gradually widens toward the rear. In other words, the front side main body 43a has a pair of incremental portions 47 that are formed on the side of the front side main body 43a in such a way that the width of the fastener element gradually increases toward the rear end of the front side main body 43a.

[0119] In addition, if Figure 5 As shown, the main body inclined surface 47a is formed on the side surfaces (upper and lower surfaces) of the front main body 43a (increase portion 47) so that the width of the fastener element gradually decreases toward the fastener element surface. The inclination angle of the main body inclined surface 47a is larger than the inclination angle of the head side inclined surface 46a.

[0120] In other words, if Figure 4 As shown, the chamfer width L1 of the head-side inclined surface 46a is wider than the chamfer width L2 of the main body inclined surface 47a.

[0121] The front half of the element 43 has a head side inclined surface 46a formed in the decreasing portion 46, so that when a pair of element components 10 are meshed, the end (edge) of the front side meshing head 43b on the surface of the element does not contact the end (edge) of the front side meshing head 43b on the surface of the element of the meshing opposite side, and a first gap S1 is formed in the up-down direction (the width direction of the element). This structure can be referred to Figure 4 .

[0122] In addition, the fastener element 40 may be configured such that the center in the thickness direction of the side surface of the fastener element 40 contacts the center in the thickness direction of the side surface of the fastener element 40 on the opposite side of the meshing when the pair of fastener element members 10 are meshed.

[0123] Moreover, predetermined gaps are formed between the plurality of fastener elements 40 constituting the same fastener element member 10 .

[0124] That is, the second gap S2 is formed along the up-down direction (element width direction) between the ends of the front body portion 43 a on the element surface between the adjacent elements 40 on the same element member 10 .

[0125] At this time, for a pair of fastener element components 10 in a meshing state, the first gap S1 is larger than the second gap S2 on the surface of the fastener element 40. At this time, since the chamfer width L1 of the head side inclined surface 46a is wider than the chamfer width L2 of the main body inclined surface 47a, the first gap S1 can be made larger than the second gap S2. This structure can be referred to Figure 4 .

[0126] According to this structure, when a pair of meshing element components 10 are bent along the length direction in the direction opposite to the surface of the element 40, before the front side meshing head 43b of the element 40 contacts the front side meshing head 43b of the element 40 on the opposite side of the meshing, the end X in the element width direction of the front side main body 43a of the element 40 can contact the end X in the element width direction of the front side main body 43a of the adjacent element 40 in the same element component 10. The details will be described later.

[0127] The front half of the chain element 43 is a portion that presents an appearance when a pair of chain element components 10 (chain element rows 11) are meshed, and has an excellent appearance shape by using a front side main body portion 43a formed in a substantially rectangular rear portion and a front side meshing head portion 43b formed in a triangular shape in which the width of the chain element gradually decreases toward the top end. Specifically, when the zipper 5 is set to a meshing state, the meshing chain elements 40 that are meshed with each other are arranged in a honeycomb shape.

[0128] like Figure 6 As shown, the front half of the chain element 43 can also be configured to have a structure in which the front side engaging head 43b is inclined downward in a manner that the thickness gradually decreases from the vicinity of the boundary with the front side main body 43a toward the top. As a result, the sliding resistance of the slider 30 is reduced, and the chain element 40 can easily and smoothly enter the slider 30, and the so-called chain element rolling can also be prevented.

[0129] The back half of the element 44 has: a back engaging head 44c that engages with the element on the opposite side; a back neck 44b that extends from the back engaging head 44c toward the rear of the element and is necked; and a back body 44a that extends from the back neck 44b further toward the rear of the element. In this embodiment, the back neck 44b and the back body 44a sandwich the fixing member 15 with the front half of the element 43.

[0130] The front body portion 43a, the back neck portion 44b, and the back body portion 44a are respectively located on the front side and the back side relative to the fixing member 15 in the height direction of the fastener element 40. That is, in the fastener element 40, the body portion 41 is fixed to the fixing member 15, and a part of the meshing portion 42 may also be fixed to the fixing member 15.

[0131] The back side main body portion 44a is formed into a roughly rectangular parallelepiped shape that gradually widens toward the rear, similarly to the front side main body portion 43a. In other words, the back side main body portion 44a has a pair of incremental portions 48 that are formed on the side of the back side main body portion 44a in such a way that the width of the chain element gradually increases toward the rear end of the back side main body portion 44a.

[0132] In addition, the element width W2 of the widest portion in the back body portion 44a is smaller than the element width W1 of the widest portion in the front body portion 43a. Figure 7 .

[0133] The back engaging head 44c and the back neck 44b are combined to form a daruma shape, thereby constituting a locking portion of the engaging portion 42 of the element back half 44. Thus, by achieving a meshing state in which a pair of element members 10 are meshed, the locking portion of the engaging portion 42 is locked with the locking portion of the engaging portion 42 of the element 40 on the meshing opposite side in a manner of being engaged with each other.

[0134] The recessed portion 45 is provided on the side portion of the main body 41 arranged opposite to the face material 6, that is, on the side portion of the main body 41 on the anti-engaging portion side (behind the element 40) located on the opposite side to the engaging portion 42 relative to the fixing member 15. The recessed portion 45 is formed so that the rear end of the element 40 is recessed toward the fixing member 15, and is provided along the width direction of the element 40. When the element 40 is injection molded, the recessed portion 45 is formed together with the connecting portion 50 described later by using a slide core (not shown) used when the element 40 is injection molded.

[0135] Specifically, the recess 45 is formed into a tapered shape in which the interval in the height direction gradually widens from the fixing member 15 side toward the counter-engaging part side by the inclined surfaces 45a and 45b formed on the front side main body 43a and the back side main body 44a, respectively. In addition, flat surfaces 45a1 and 45b1 parallel to each other are formed at the opening edge of the recess 45 in a manner adjacent to the inclined surfaces 45a and 45b.

[0136] Further, a connecting portion 50 is provided in the recessed portion 45 , connecting the front body portion 43 a and the back body portion 44 a at the center portion in the width direction of the fastener element 40 , and contacting the fixing member 15 at the anti-engaging portion side.

[0137] The connecting portion 50 is formed into a substantially trapezoidal shape in a cross section along the height direction of the fastener element 40 and has a flat side surface 50a connected to the inclined surfaces 45a and 45b of the front body portion 43a and the back body portion 44a on the anti-engaging portion side.

[0138] Therefore, if Fig. 9As shown, the main body portion 41 of the fastener element 40 covers the entire outer peripheral surface of the fixing member 15 held in the center portion in the height direction of the fastener element 40 in the center portion in the width direction of the fastener element 40 .

[0139] The connecting portion 50 may be of a size sufficient to ensure the rigidity of the main body 41 of the fastener element 40, and may have a thickness T1 (see FIG. 1 ) that is at least 1 / 4 of the depth D2 of the recessed portion 45 at both ends in the width direction of the fastener element 40. Fig. 9 ), preferably having a width W3 that is 1 / 4 or more of the width dimension of the fastener element 40 in the width direction of the fastener element 40 (refer to Figure 8 ).

[0140] like Fig. 9 As shown, the recess 45 is formed in such a way that the depth D2 at both ends in the width direction is deeper than the depth D1 at the center in the width direction of the fastener element 40. Thus, when the fastener element component 10 is sewn to the fastener element mounting edge 7 of the fabric 6, the fastener element mounting edge 7 of the fabric 6 accommodated in the recess 45 can enter the meshing portion side further at the two ends in the width direction than at the center in the width direction of the fastener element 40.

[0141] As a result, if Figure 1 and Figure 2 As shown, when viewed from the front and back directions of the chain element component 10, there is no gap between the fixing components 15 between adjacent chain elements 40 and the chain element mounting edge 7 of the fabric 6 opposite to the fixing components 15, or the gap is small enough to improve the appearance of the zipper product 1.

[0142] In addition, Figure 2 In the figure, for convenience of explanation, a gap is provided between the fixing member 15 and the element mounting edge 7 of the fabric 6, but in fact, since the fixing member 15 has elasticity, the fixing member 15 bulges slightly in the front-rear direction of the element 40, and the gap is not noticeable. In addition, since the depth D1 of the recessed portion at the center portion in the width direction of the element 40 is shallower than the depth D2 at both ends in the width direction, the rigidity of the main body 41 of the element 40 can be ensured.

[0143] On the other hand, at the center of the width direction of the fastener element 40, the opposite side edge 7a of the fastener element mounting edge 7 abuts against the connecting portion 50, and the top end portion is bulged in the height direction of the fastener element 40 and is accommodated in the recess 45. Figure 3 .

[0144] As described above, in the product 1 with a zipper of the present embodiment, the depth of the recess 45 formed on the anti-meshing portion side of the main body 41 is formed in a manner that is deeper at both ends in the width direction than at the center in the width direction of the link tooth 40. Therefore, the link tooth mounting edge 7 of the fabric 6 accommodated in the recess 45 can enter the meshing portion side further at both ends in the width direction than at the center in the width direction of the link tooth 40.

[0145] Therefore, when viewed from the front and back directions of the chain element component 10, there is no gap between the fixing components 15 between adjacent chain elements 40 and the chain element mounting edge 7 of the fabric 6 opposite to the fixing components 15, or the gap is small enough to improve the appearance of the zipper product 1.

[0146] Next, based on Figure 10 to Figure 13 The operation and effect when the pair of element members 10 in the meshing state are bent in the longitudinal direction will be described.

[0147] Fig.10 It is a front view of the main part showing the fastener element component in a meshing state bent along the longitudinal direction. Fig.11 yes Fig.10 A back perspective view of the main parts. Fig.12 yes Fig.10 Side view of. Fig.13 yes Fig.10 The fixing member 15 is a linear member extending along the length direction in a manner that is bridged between the fastener elements 40. Fig.11 and Fig.12 In the figure, for the convenience of identification, the representation between adjacent fastener elements 40 is omitted.

[0148] According to the fastener element component 10 of the present embodiment, when a pair of fastener element components 10 (fastener element rows 11) in the meshing state are bent in the direction in which the fastener element surface half portions 43 (the surfaces of the fastener elements 40) are opposite to each other, before the front side meshing head portion 43b contacts the front side meshing head portion 43b on the opposite side of the meshing, the fastener element width direction end portion X of the front side main body portion 43a can contact the fastener element width direction end portion X of the front side main body portion 43a of the adjacent fastener element 40 on the same fastener element component 10. At this time, the end portion X of the front side main body portion 43a becomes the width direction end portion of the widest portion of the fastener element width W1.

[0149] In other words, if the pair of fastener element members 10 in the meshing state are bent in the direction in which the fastener element surface halves 43 are opposed to each other, Fig.12 As shown, the end X of the front body portion 43a in the element width direction contacts the end X of the front body portion 43a in the element width direction of the adjacent element 40 on the same element member 10 (on the fixing member 15). Fig.13As shown, the meshing portion 42 (front-side meshing head 43 b ) of the fastener element 40 is not in contact with the meshing portion 42 (front-side meshing head 43 b ) of the fastener element 40 on the opposite side of the meshing, and a gap S is formed.

[0150] According to this structure, even when a pair of chain tooth parts 10 in a meshing state are bent along the length direction, the posture of the main body 41 of the chain tooth 40 is more stable, thereby preventing the main body 41 of the chain tooth 40 (the width direction end of the front side main body 43a) from entering the recess 45 of the adjacent chain tooth 40.

[0151] That is, the fastener element 10 is as follows Figure 7 As shown in FIG. 1 , the width of the fastener element of the front side main body portion 43a (the rear end portion) of the fastener element front half portion 43 is set to a wide width, and, as shown in FIG. Figure 4 As shown, by configuring the pair of element members 10 in the meshing state so that the first gap S1 is greater than the second gap S2, the occurrence of the chain separation can be effectively prevented.

[0152] In addition, regarding the fastener element component 10, when a pair of fastener element components 10 in a meshing state are bent in the direction in which the fastener element back half portions 44 (back sides of the fastener elements 40) are relative to each other, the fastener element width direction end portion of the back side main body portion 44a contacts the fastener element width direction end portion of the back side main body portion 44a of the fastener element 40 adjacent to the same fastener element component 10. On the other hand, it is also possible to set the meshing portion 42 (back side meshing head 44c and back side neck 44b) of the fastener element 40 to be non-contact with the meshing portion 42 (back side meshing head 44c and back side neck 44b) of the fastener element 40 on the meshing opposite side.

[0153] Furthermore, the engaging portion 42 (back neck portion 44b and back engaging head portion 44c) of the element back half portion 44 formed in a tumbler shape may be in contact with the engaging portion 42 formed in a tumbler shape on the opposite side of the engagement so as to fit.

[0154] According to this structure, compared with the case where the pair of meshing element members 10 are bent in the direction in which the element surface half portions 43 are opposite to each other, the elements 40 constituting the meshing element members 10 are in contact with each other at multiple locations at various angles. Therefore, the posture of the elements 40 is stabilized, and chain separation is unlikely to occur.

[0155] In addition, regarding the shape of the meshing portion 42 of the front half portion 43 of the element, the first gap S1 between the front meshing heads 43b on the surfaces of the adjacent meshing opposite sides of the elements 40 may be larger than the second gap S2 between the front body portions 43a on the surfaces of the adjacent elements 40 mounted on the same fixing member 15, and the shape is not limited to the above example. That is, the shape of the front meshing head (special-shaped portion) 43b of the element 40 can be changed according to the design of the slide fastener 5.

[0156] Moreover, in the above-mentioned embodiment, the deformed portion 43 b is arranged on the front side of the element member 10 , but a structure in which the deformed portion 43 b is arranged on the back side of the element member 10 may be adopted.

[0157] In addition, in the above-mentioned embodiment, clothes are described as zipper products, but the zipper products of the present invention include not only clothes (clothing products), but also various products such as daily necessities such as shoes and bags, industrial materials, various cover cloths for automobiles, trains, aircraft, etc.

[0158] In addition, the present invention is not limited to the above-mentioned embodiment, and can be appropriately changed, improved, etc. within the scope of implementation.

[0162] The above-mentioned fastener element (40) comprises: an engaging portion (42) which engages with the above-mentioned fastener element (40) on the opposite side of the engagement; and a main body (41) which extends from the above-mentioned engaging portion (42) in the left-right direction and is fixed to the above-mentioned fixing member (15).

[0163] In the main body (41), a recess (45) is provided along the longitudinal direction on the anti-engaging portion side located on the opposite side of the engaging portion (42) relative to the fixing member (15).

[0164] When the left and right pair of zipper tooth components (10, 10) are meshed, and when the left and right pair of zipper tooth components (10, 10) are bent along the length direction in the direction in which the surfaces or backs of the tooth components (40) are relative to each other, when the main bodies (41) of the adjacent tooth components (40) of the zipper tooth components (10) are in contact with each other, the meshing portions (42) of the adjacent tooth components (40) of the left and right pair of zipper tooth components (10, 10) are not in contact with each other.

[0165] According to this configuration, when a pair of meshing element rows are bent in the longitudinal direction, the main bodies of the elements adjacent in the longitudinal direction on the same element member first contact each other, thereby stabilizing the posture of the elements and preventing disengagement of the elements.

[0166] (2) The slide fastener chain component according to (1), wherein:

[0167] The fastener element width (W1, W2) of the main body (41) in the longitudinal direction is formed to be wider toward the end portion on the anti-engaging portion side.

[0171] The meshing portion (42) comprises: a locking portion (44b, 44c) which is arranged on the back side of the link tooth (40) and is formed into an elliptical shape; and a special-shaped portion (43b) which is arranged on the front side of the link tooth (40) and is formed into a narrow width toward the top end.

[0172] When the above-mentioned left and right pair of zipper chain tooth components (10, 10) are in a state of being meshed, when the above-mentioned left and right pair of zipper chain tooth components (10, 10) are bent in directions relative to each other along the above-mentioned length direction on the surfaces of the above-mentioned chain teeth (40), when the above-mentioned main body portions (41) of the above-mentioned adjacent chain teeth (40) of the above-mentioned left and right pair of zipper chain tooth components (10, 10) are in contact with each other, the above-mentioned special-shaped portions (43b) of the above-mentioned adjacent chain teeth (40) of the above-mentioned left and right pair of zipper chain tooth components (10, 10) are not in contact with each other.

[0173] According to this structure, the appearance of the front side of the fastener element visually recognized in the meshed state is improved. In addition, even when the deformed portion is provided, the posture of the fastener element when the pair of fastener element members are bent is stable, and the occurrence of chain separation can be prevented.

[0175] In the main body (41), the front element width of the element (40) provided with the special-shaped portion (43b) is greater than the back element width of the element (40) provided with the locking portion (44b, 44c).

[0176] According to this configuration, the appearance of the front side of the fastener element visually recognized in the meshed state can be improved, and the occurrence of the chain separation can be effectively prevented.

[0178] The slide fastener chain component according to any one of (1) to (4);

[0179] A slider (30) for engaging the pair of left and right slide fastener element components (10, 10); and

[0180] A zipper installation component (7, 7) is used to install the above-mentioned pair of left and right zipper element components (10, 10).

[0181] According to this structure, even when a pair of meshing element rows bends in the longitudinal direction, it is possible to prevent the meshing of the elements from being released, thereby improving the convenience and durability of the product with a slide fastener.
