[0042] The following describes non-limiting embodiments and features of the present invention with reference to the accompanying drawings. Those skilled in the art will be able to combine the various embodiments and / or features without further explanation and appreciate the synergistic effects resulting from such combinations. In principle, redundant descriptions between the various embodiments will be omitted. The accompanying drawings are primarily intended to illustrate the invention and are simplified for ease of illustration. Each feature is not specific to the fastening components disclosed in this specification and should be understood as a general feature common to various other fastening components not disclosed in this specification.

[0043] In this specification, the moving direction of the slider 8 for opening and closing the slide fastener 1 is referred to as the front-back direction (see Figure 1 The double-headed arrow FB). A direction equal to the width direction of the slide fastener 1 and perpendicular to the front-back direction is defined as the left-right direction (refer to Figure 1The double-headed arrow LR). The direction equal to the thickness direction of the zipper 1 and perpendicular to the front-to-back direction is defined as the up-down direction. In addition, the up-down direction is perpendicular to the front-to-back direction and the left-to-right direction. The up-down direction does not necessarily mean the vertical direction (the direction of gravity). For example, when the longitudinal direction of the zipper 1 is configured as the vertical direction, the up-down direction related to the zipper 1 is included in the horizontal direction (perpendicular to the vertical direction). Thus, the directions referenced in this specification have nothing to do with the vertical direction.

[0044] Reference Figures 1 to 3 Provide explanation. Figure 1 This is a schematic perspective view of the slide fastener 1 according to one embodiment of the present disclosure. Figure 2 It is a schematic plan view of the slide fastener 1 attached to a cloth serving as an article 9 . Figure 3 It is a schematic cross-sectional view of the slide fastener 1 attached to the cloth.

[0045] The zipper 1 comprises a pair of left and right fastening components 2 and 2' as a fastening device 2A, and a slider 8 that can move forward and backward to engage and disengage the pair of left and right fastening components 2 and 2'. The left and right fastening components 2 and 2' are engaged by advancing the slider 8, and disengaged by retreating the slider 8. Furthermore, the left and right fastening components 2 and 2' can be engaged in a hook-to-hook manner. The fastening components 2 and 2' are typically made of a flexible resin, such as polyester. Due to their regular structure in the longitudinal direction, the fastening components 2 and 2' can be mass-produced using various molding techniques. By making the fastening components 2 and 2' very long (e.g., 10 meters), the fastening components 2 and 2' can be cut out of them to any length (e.g., 50 cm). The ability to manufacture the fastening components 2 and 2' without considering the final product length is an advantage related to mass production. Furthermore, depending on the application, it is also conceivable to make the fastening members 2, 2' harder and reduce their flexibility.

[0046] The slider 8 has an upper wing plate 81, a lower wing plate 82, and a connecting column 83 extending in the vertical direction and connecting the front ends of the upper wing plate 81 and the lower wing plate 82, thereby defining a Y-shaped passage for the left and right fastening components 2, 2'. The slider 8 is typically made of resin, metal or ceramic. Upper flange walls 86 that rise downward are provided on the left and right side edges of the upper wing plate 81. Similarly, lower flange walls 87 that rise upward are provided on the left and right side edges of the lower wing plate 82. In this way, the movement path of the left and right fastening components 2, 2' is restricted in the width direction of the slider 8. In addition, as described later, the upper and lower intervals between the upper wing plate 81 and the lower wing plate 82 are designed to correspond to the width of the fastening components 2, 2'.

[0047] The fastening members 2 and 2' are long members that can be attached to the edge 91 of the article 9 directly or through an intervening object (for example, a flexible thin material such as other cloth) (see Figure 2 and Figure 3 ). The article 9 to which the fastening components 2 and 2' are directly attached is, for example, a highly flexible fabric such as fabric for clothing, fabric for bags, or fabric for shoes. The edge 91 of the article 9 is the edge that defines the opening opened and closed by the zipper 1. In some cases, the edge 91 is a folded end formed by folding the fabric, which can promote efficient sewing of the fastening components 2 and 2' to the fabric as described later. In addition, when the fabric is folded, the fabric has a main fabric 92 and a sub-fabric 93 (see Figure 3 ), they are overlapped and a folded end is formed between them. The main fabric 92 and the auxiliary fabric 93 can be sewn together by one or more sewing threads 200 along the side edge 95 of the auxiliary fabric on the side opposite to the folded end.

[0048] In some cases, the width W2 of the fastening members 2 and 2' in the vertical direction is greater than the width W91 of the article 9 (the stacked thickness of the main fabric 92 and the sub-fabric 93). Advantageously, the protrusion height H2 of the fastening members 2 and 2' from the main surface of the article 9 (the upper surface of the main fabric 92) is 1 cm or less (i.e., within the range of 0 to 1 cm) or 0.8 cm or less (i.e., within the range of 0 to 0.8 cm). Furthermore, the main surface of the article 9 refers to either its upper or lower surface. Depending on the type and condition of the article 9, the width W2 of the fastening members 2 and 2' may be equal to or less than the width W91 of the article 9 (the stacked thickness of the main fabric 92 and the sub-fabric 93).

[0049] For the sake of caution, when the fastening members 2, 2' are directly attached to the fabric, omitting the zipper tape can contribute to the weight reduction of the fabric with the fastening members, increase its flexibility, and improve its aesthetics. Furthermore, this disclosure does not exclude the use of a zipper tape as the article 9, except where explicitly excluded by the phrase "articles (excluding zipper tape)."

[0050] Reference Figures 4 to 7 , the structure of the fastening components 2 and 2' will be described. Figure 4 2 is a schematic partial perspective view of the fastening members 2, 2', showing the mounting surface 2a provided on one side in the thickness direction thereof. Preferably, the fastening members 2, 2' are formed in mirror symmetry with respect to the center line CX thereof. Figure 5 It is a schematic partial perspective view of the fastening members 2 and 2 ′, showing an engaging structure 2 b provided on the opposite side of the mounting surface 2 a in the thickness direction thereof. Figure 6 It is a schematic side view of the fastening members 2 and 2 ′, and particularly shows the engagement element rows 21 to 24 , the recess 55 , and the slits S1 and S2 . Figure 7It is along Figure 6 The schematic cross-sectional view of the fastening components 2 and 2' shown in dashed lines is shown in FIG. The directions associated with the fastening components 2 and 2' can be aligned with the directions associated with the zipper 1 as follows: The length direction of the fastening components 2 and 2' coincides with the front-to-back direction of the zipper 1. The width direction of the fastening components 2 and 2' coincides with the top-to-bottom direction of the zipper 1. The thickness direction of the fastening components 2 and 2' coincides with the left-to-right direction of the zipper 1.

[0051] The fastening members 2 and 2' have a mounting surface 2a ( Figure 4 and the engaging structure 2b ( ) provided on the opposite side of the mounting surface 2a in the thickness direction of the fastening member 2, 2 '. Figure 5 ). The thickness (thickness direction) of the fastening components 2, 2' can be defined as the height (height direction) of the engaging structure 2b from the mounting surface 2a. The engaging structure 2b of the fastening components 2, 2' is arranged to face or abut the engaging structure of the fastening component of the engaging object, and can be engaged therewith. The mounting surface 2a of the fastening components 2, 2' is arranged to at least partially face or at least partially abut the edge 91 of the article 9 to which the fastening components 2, 2' are mounted, and can be mounted on the edge. The mounting surface 2a can have a flat surface at least in part, but is not limited to this. The flat surface of the mounting surface 2a can be oriented orthogonally to the left-right direction in the zipper 1.

[0052] The engaging structure 2b includes one or more engaging element rows of engaging elements 30 arranged along the longitudinal direction of the fastening members 2 and 2'. In the illustrated example, the engaging element rows 21 to 24 are arranged side by side in the width direction of the fastening members 2 and 2' (for example, see FIG. Figures 4 to 6 ). The engaging element rows 21 to 24 are sometimes referred to as the first to fourth engaging element rows 21 to 24, respectively, to distinguish them. Each engaging element 30 is hook-shaped (not loop-shaped), and includes a base 31 that rises to the side opposite to the mounting surface 2a and at least one protrusion 32 that protrudes from the base 31 along the length direction of the fastening member 2, 2' (for example, see Figure 7 Accommodation spaces 33 for accommodating the engaging elements of the fastening components to be engaged are formed between adjacent engaging elements 30 in the engaging element rows 21 to 24. The width W33 of the accommodation spaces 33 in the thickness direction of the fastening components 2 and 2' can gradually increase as the protrusions 32 extend away from the base 31.

[0053] like Figure 6As shown, the engaging element rows 21 and 23 whose protrusions 32 project in opposite directions in the longitudinal direction of the fastening members 2 and 2' can be arranged adjacent to each other as a group. The same applies to the engaging element rows 22 and 24. In this case, the force required to engage or disengage the fastening members 2 and 2' with each other is increased, which can improve the horizontal pulling strength of the zipper 1. In addition, the arrangement direction of the engaging elements 30 in the engaging element rows 21 to 24 is consistent with the longitudinal direction of the fastening members 2 and 2'. In the case where there are two or more engaging element rows 21 to 24, the arrangement direction of these engaging element rows 21 to 24 is consistent with the width direction of the fastening members 2 and 2'.

[0054] The structure of the fastening members 2, 2' (particularly the structure of the engagement element arrays 21 to 24) can be described as being formed by alternately connecting the engagement elements 30 and the connection portions 70 (see Figure 7 The connecting portion 70 is a thin portion that connects the engaging element 30. The minimum thickness of the fastening components 2 and 2' is defined by the upper and lower surfaces of the connecting portion 70. Grooves 36, described later, can be formed between adjacent connecting portions 70 in the longitudinal direction of the fastening components 2 and 2'. Furthermore, grooves 37 and slits S1 and S2, described later, can be formed in each connecting portion 70.

[0055] The fastening parts 2, 2' may further include a mounting portion 27 extending in the longitudinal direction thereof. The mounting portion 27 may be a continuous portion or a portion divided into a plurality of portions along the longitudinal direction of the fastening parts 2, 2'. The fastening parts 2, 2' are mounted on the edge 91 of the article 9 directly or via an intervening object at the mounting portion 27 other than the position where the engaging element columns 21 to 24 thereof are formed. Advantageously, the mounting portion 27 is provided between the engaging element columns (for example, the engaging element column 21 and the engaging element column 22) adjacent in the width direction of the fastening parts 2, 2', preferably, on the center line CX of the fastening parts 2, 2'. Thus, it is facilitated to arrange the engaging element columns 21, 22 (optionally, in addition to these, there are the engaging element columns 23, 24) on both sides of the mounting portion 27 at the thickness center of the edge 91 (see Figure 3 On both sides of the plane PL0), the edges 91 of the article 9 can be well connected to each other via the fastening device 2A. Figure 3 The sewing thread 96 for sewing the attachment portion 27 to the edge portion 91 can exist or be included in the plane PL0 located at the thickness center of the edge portion 91. The main fabric 92 and the sub-fabric 93 are arranged on both sides of the plane PL0.

[0056] The mounting portion 27 can be formed thinner than the engaging element 30 in the thickness direction of the fastening components 2 and 2'. When the fastening components 2 and 2' are sewn to the edge 91, the sewing needle can be passed through the mounting portion 27 with less force. When the fastening components 2 and 2' are welded to the edge 91, the heat capacity of the mounting portion 27 is reduced, thereby promoting smoother welding. Depending on the circumstances, the mounting portion 27 is formed thinner than the connecting portion 70. In some cases, the mounting portion 27 can be set as a thickness portion having a (constant or different) thickness from the bottom surface 53g of the receiving groove 53 described later, or a wall having a (constant or different) height from the bottom surface 53g of the receiving groove 53 described later. The mounting portion 27 can directly contact the article 9 at the bottom surface 53g of the receiving groove 53.

[0057] Additionally or alternatively, the mounting portion 27 can be formed narrower than the engaging element rows 21 to 24 in the width direction of the fastening components 2 and 2'. This facilitates forming the engaging element rows 21 to 24 (and the engaging elements 30) with a desired width. Alternatively, the first engaging element row 21 and the third engaging element row 23 can be directly adjacent to each other with a gap smaller than the mounting portion 27 in the width direction of the fastening components 2 and 2', and the second engaging element row 22 and the fourth engaging element row 24 can be directly adjacent to each other with a gap smaller than the mounting portion 27, thereby facilitating a high-density arrangement of the engaging element rows.

[0058] The mounting portion 27 is formed with at least one recess 55 for accommodating the stitches 97 of the suture 96 used to sew the fastening components 2, 2' to the edge 91. Typically, the mounting portion 27 is formed as a wall having at least one recess 55 formed on its top surface. When the fastening components 2, 2' of the fastening device 2A are engaged with each other, the top surfaces of the walls of the mounting portions 27 of the respective fastening components 2, 2' are adjacent to each other and / or face each other (with or without a suture). Multiple recesses 55 can be provided at predetermined intervals (corresponding to the spacing of the stitches 97) along the length of the fastening components 2, 2' (more preferably, along the centerline CX of the fastening components 2, 2'). Each of the multiple recesses 55 is preferably elongated in the length direction of the fastening components 2, 2'. The thinned wall of the fastening components 2, 2', which is thinned by the sewing needle penetrating through the recesses 55, facilitates the sewing of the fastening components 2, 2' to the article 9. Furthermore, additional recesses 55 may be provided in the fastening members 2, 2' at locations other than the mounting portions 27. It should also be noted that the mounting portions 27 may be provided at locations other than between the first and second engagement element rows 21, 22 adjacent in the width direction of the fastening members 2, 2'.

[0059] The fastening components 2 and 2' can have guide walls 25 and 26 on both sides of the locking element array 21 to 24 (typically, the two side edges of the fastening components 2 and 2') in the width direction thereof. The guide walls 25 and 26 can be set at a position farthest from the center line CX of the fastening components 2 and 2' in the width direction of the fastening components 2 and 2'. The guide wall 25 can contact one of the lower surface of the upper wing plate 81 of the slider 8 and the upper surface of the lower wing plate 82, and the guide wall 26 can contact the other of the lower surface of the upper wing plate 81 of the slider 8 and the upper surface of the lower wing plate 82, thereby assisting the slider 8 in moving smoothly along the fastening components 2 and 2' and suppressing damage to the locking element 30 due to collision between the slider 8 and the locking element 30. In addition, in the zipper 1, these locking element arrays 21 to 24, the guide walls 25 and 26, and the mounting portion 27 are arranged in the up-down direction.

[0060] One or more of the guide walls 25 and 26 can be formed as a wall portion row having a plurality of wall portions arranged at predetermined intervals along the longitudinal direction of the fastening member 2, 2', so as to avoid reducing the flexibility of the fastening member 2, 2'. The same applies to the mounting portion 27. Figure 5 The guide wall 25 includes wall portions 25g arranged at a predetermined spacing (equal to the spacing between the engagement elements 30) along the length of the fastening components 2 and 2', with a groove 25j formed therebetween. The groove 25j is spatially connected to the accommodation space 33 formed between the engagement elements 30 in the width direction of the fastening components 2 and 2'. The description of the guide wall 25 also applies to the guide wall 26, where the wall portion 25g is replaced by the wall portion 26g and the groove 25j is replaced by the groove 26j. The description of the guide wall 25 also applies to the mounting portion 27, where the wall portion 25g is replaced by the wall portion 27g and the groove 25j is replaced by the groove 27j. This improves the flexibility of the fastening components 2 and 2'.

[0061] At least one guide protrusion 51, 52 is provided on the mounting surface 2a and is arranged between the upper flange wall 86 and the lower flange wall 87 of the slider 8. When the pair of fastening components 2, 2' are accommodated in the moving path between the upper wing plate 81 and the lower wing plate 82 of the slider 8, the guide protrusions 51, 52 provided on the mounting surface 2a of each fastening component 2, 2' are arranged between the upper and lower flange walls 86 and the lower flange wall 87 of the slider 8. In the example shown in the figure, two rows of guide protrusions 61, 62 in which the guide protrusions 51, 52 are arranged in the longitudinal direction of the fastening components 2, 2' are provided on the mounting surface 2a (see FIG. Figure 4The guide protrusions 51 and 52 are located away from the ends of the fastening components 2 and 2' in the width direction of the fastening components 2 and 2', and guide surfaces 56 and 57 are formed at the ends of the fastening components 2 and 2' in the width direction. As a result, interference between the fastening components 2 and 2' and the upper flange wall 86 and lower flange wall 87 of the slider 8 on both sides of the fastening components 2 and 2' in the width direction can be avoided. Specifically, a stable engagement of the slider 8 with respect to the fastening components 2 and 2' can be achieved, which allows the slider 8 to slide relative to the fastening components 2 and 2'. Specifically, the guide surfaces 56 and 57 face or contact the upper flange wall 86 and lower flange wall 87 of the slider 8, thereby restricting the movement of the fastening components 2 and 2' in the width direction of the slider 8 and promoting smooth movement of the slider 8. The guide surfaces 56 and 57 are typically formed as flat surfaces, but are not limited to this.

[0062] Each guide protrusion 51 has a first side surface 51p and a second side surface 51q in the width direction of the fastening components 2 and 2'. Similarly, each guide protrusion 52 has a first side surface 52p and a second side surface 52q in the width direction of the fastening components 2 and 2'. In the zipper 1, the first side surface 51p of the guide protrusion 51 faces or contacts the lower surface of the upper flange wall 86, thereby assisting in the smooth movement of the slider 8. Similarly, the first side surface 52p of the guide protrusion 52 faces or contacts the upper surface of the lower flange wall 87, thereby assisting in the smooth movement of the slider 8. The second side surface 51q of the guide protrusion 51 faces opposite the first side surface 51p. Specifically, it faces the second side surface 52q of the guide protrusion 52 across the center line CX of the fastening components 2 and 2'. The second side surface 52q of the guide protrusion 52 faces opposite the first side surface 52p. Specifically, it faces the second side surface 51q of the guide protrusion 51 across the center line CX of the fastening components 2 and 2'. The bottom surface 53g of the receiving groove 53 having the edge portion 91 is formed between the second side surfaces 51q and 52q of the guide protrusions 51 and 52. Figure 1 In the slide fastener 1 shown, the first side surface and the second side surface can be referred to as upper and lower surfaces instead.

[0063] By providing the guide protrusions 51 and 52, it is possible to facilitate ensuring that the vertical distance between the upper flange wall 86 and the lower flange wall 87 is sufficiently wide (see Figure 3 Specifically, a gap is provided between the main fabric 92 and the upper flange wall 86 to suppress or prevent wear thereof. Additionally or alternatively, a gap is provided between the auxiliary fabric 93 and the lower flange wall 87 to suppress or prevent wear thereof. In some cases, the gap between the lower surface of the upper flange wall 86 and the upper surface of the lower flange wall 87 is larger than the gap W9 between the first side surfaces 51p, 52p of the guide protrusions 51, 52 of the fastening members 2, 2' (see Figure 4 ) is slightly larger.

[0064] By forming the receiving groove 53 for receiving the edge 91 between the guide protrusions 51 and 52 as described above, the fastening member 2 or 2' can be more stably supported by the edge 91 of the article 9. Of course, the present invention is not limited to this, and the guide protrusions 51 and 52 can also be connected to each other in the width direction of the fastening member 2 or 2' to form a single guide protrusion.

[0065] To enhance the flexibility of the fastening components 2, 2', a groove 36 can be recessed (thinned) through the base 31 of the engaging element 30 in the mounting surface 2a. The groove 36 can extend along the width direction of the fastening components 2, 2' at a constant or variable depth D36. The grooves 36 are formed along the length of the fastening components 2, 2' at a pitch P1 that is the same as the pitch P1 of the engaging elements 30. Of course, the pitch of the grooves 36 can also be set to a multiple of the pitch of the engaging elements 30. Furthermore, the grooves 36 can extend across the entire width of the fastening components 2, 2', for example, through the guide walls 25, 26 and the walls 25g, 26g, 27g of the mounting portion 27. As a result, one open end of the groove 36 is formed on the side surface of the guide wall 25 in the width direction of the fastening components 2, 2', and the other open end of the groove 36 is formed on the side surface of the guide wall 26. In the longitudinal direction of the fastening members 2 , 2 ′, each groove 36 is sandwiched between the guide protrusions 51 arranged adjacent to each other in the same direction, and similarly, between the guide protrusions 52 .

[0066] To improve the flexibility of the fastening members 2 and 2', grooves 37 can be formed between adjacent engaging elements 30 in the longitudinal direction of the fastening members 2 and 2' to reduce the thickness of the fastening members 2 and 2'. Grooves 36 and 37 are formed alternately along the longitudinal direction of the fastening members 2 and 2'. Grooves 36 can be deeper than grooves 37 by an amount extending through the base 31 of the engaging elements 30, but this is not necessarily the case. The pitch P2 of the grooves 37 is the same as the pitch P1 of the engaging elements 30, but can also be a multiple thereof.

[0067] A plurality of slits S1 and S2 can be formed extending in the width direction of the fastening parts 2 and 2'. Each of the plurality of slits S1 and S2 is located between the engaging elements 30 adjacent in the length direction of the fastening parts 2 and 2'. In this way, the fastening parts 2 and 2' are easily deformed (for example, easily bent or twisted in the left-right direction and / or the up-down direction). By forming the slits S1 and S2 in the fastening parts 2 and 2', it is expected that the fastening parts 2 and 2' can be easily bent to follow the deformation of the edge 91 when attached to the edge 91 of the article 9. Preferably, each of the plurality of slits S1 and S2 is formed to a length exceeding half of the width of the fastening parts 2 and 2'. In addition, the slit S1 is an upper slit extending downward from the upper edge of the fastening parts 2 and 2' toward the lower edge thereof. The slit S2 is a lower slit extending upward from the lower edge of the fastening parts 2 and 2' toward the upper edge thereof.

[0068] As can be seen from the above description, the fastening members 2 and 2' of the present disclosure have a mounting surface 2a ( Figure 4 and the engaging structure 2b ( ) provided on the opposite side of the mounting surface 2a in the thickness direction of the fastening member 2, 2 '. Figure 5 The engaging structure 2b includes one or more rows of engaging elements 21-24 arranged along the length of the fastening member 2, 2'. Each engaging element 30 is arranged upright on the side opposite to the mounting surface 2a. This provides a fastening member 2, 2' that can be directly mounted on an article 9 and is suitable for mass production.

[0069] Although it is repeatedly described, the fastening components 2, 2' can be directly mounted on the edge 91 of the article 9. Therefore, by using the fastening components 2, 2', a zipper 1 without a zipper tape can be formed. Advantageously, the fastening components 2, 2' are selectively mounted on the article 9 at one of the mounting portions 27 (which may include the bottom surface 53g of the accommodating groove 53) in the width direction thereof. In addition, as described above, the mounting portion 27 may be long in the length direction of the fastening components 2, 2'. In the case of using the above-mentioned fastening components 2, 2' as the left and right fastening components 2, 2', the zipper 1 has the following characteristics. The left fastening component 2 is a component that is long in the front-to-back direction and is sewn to the left edge of the opening of the article 9 to which the zipper 1 is mounted by stitches 96 directly or via an interposition, and includes a left-side snap-fit ​​element column having at least one column of left-side snap-fit ​​elements arranged along the length direction of the left fastening component 2, and the left-side snap-fit ​​elements protrude to the right side on the side opposite to the left edge of the opening. The right fastening component 2' is a component elongated in the front-to-back direction and is sewn directly or via an intervening object to the right edge of the opening of the article 9 by stitching 96. The component includes at least one row of right-side engaging elements arranged along the length of the right fastening component 2', with the right-side engaging elements projecting to the left, opposite the right edge of the opening. By replacing the directions associated with the fastening components 2 and 2' with the directions associated with the zipper 1 (up-down, front-back, and left-right), the various features described above regarding the fastening components 2 and 2' can also be applied to the zipper 1.

[0070] Depend on Figure 8As can be seen, when the slider 8 advances, the engaging element 30 that enters the slider 8 from the front opening moves through the passageway between the connecting post 83 and the upper and lower flange walls 86 and 87. Next, it engages with the engaging element 30 it is engaging with at a position behind the connecting post 83, and finally moves out of the slider 8 through the rear opening of the slider 8. When the slider 8 retreats, the engaged left and right engaging elements 30 enter the slider 8 through the rear opening of the slider 8, disengage at a position behind the connecting post 83, move through the left and right passageways of the connecting post 83, and finally move out of the slider 8 through the left and right front openings of the connecting post 83. The guide protrusions 51 and 52 are sandwiched between the upper and lower flange walls 86 and 87 of the slider 8, thereby promoting stable sliding movement of the slider 8. The grooves 36 and / or 37 formed in the fastening members 2 and 2 ′ provide the fastening members 2 and 2 ′ with improved flexibility, thereby reducing the sliding resistance of the slider 8 .

[0071] like Figure 9 As shown, the fastening components 2 and 2' can be manufactured by supplying molten resin from a discharge portion 103 between two adjacent die wheels 101 and 102. Furthermore, although not shown, a cavity capable of molding the engaging structure 2b of the fastening components 2 and 2' is formed on one circumferential surface of the die wheels 101 and 102, and a cavity capable of molding the structure on the mounting surface 2a side of the fastening components 2 and 2' is formed on the other circumferential surface.

[0072] When the item 9 is a cloth, Figures 10 to 12 The steps shown attach the fastening member 2 directly to the fabric (the same applies to the fastening member 2'). Figure 10 In the embodiment of the present invention, the fastening component 2 is sewn to the fabric along the side edge 95 (for example, at the attachment portion 27) using a stitch 96 at a position away from the side edge 95 of the fabric toward the inside of the fabric (i.e., away from the perpendicular plane PL1 relative to the side edge 95 and parallel thereto). The fastening component 2 is selectively attached to a predetermined portion of the fabric (the portion that becomes the folded end, as described later) at the attachment portion 27, and is not attached to the fabric in other portions (for example, the portion where the rows of engaging elements 21 to 24 are provided). Furthermore, when the fastening component 2 is placed on the placement surface 98 of the article 9, the protruding direction of the engaging elements 30 is aligned with a direction away from the placement surface 98 of the article 9 (for example, a perpendicular direction). Various sewing methods can be used, such as flat stitching, single-thread lockstitching, and double-thread lockstitching. Furthermore, the sewing direction of the stitch 96 is aligned with the longitudinal direction of the fastening component 2.

[0073] In addition to or in lieu of sewing, the fastening member 2 can be secured to the article 9 by ultrasonic welding. The fastening member 2 is placed on the placement surface 98 of the article 9 so that the mounting surface 2a of the fastening member 2 (e.g., the bottom surface 53g of the receiving groove 53 between the guide protrusions 51 and 52) contacts the placement surface 98 of the article 9. The shape of the anvil is optimized to ensure reliable contact between the fastening member 2 and the article 9. In some cases, a protrusion is provided on the anvil to protrude between the guide protrusions 51 and 52.

[0074] Next, the horn is brought into contact with the fastening member 2 (e.g., the mounting portion 27) to apply ultrasonic vibrations to the fastening member 2. At this point, the fastening member 2 (e.g., the bottom surface 53g of the receiving groove 53) is welded to the article 9 on the side opposite the contact point of the horn (e.g., the mounting portion 27). The horn is moved in the longitudinal direction of the fastening member 2, or the fastening member 2 is moved relative to the horn, which is stationary at a predetermined position. This allows for continuous or intermittent weld formation along the longitudinal direction of the fastening member 2, thereby securing the fastening member 2 to the article 9. Both the fastening member 2 and the article 9 are made of resin.

[0075] exist Figure 11 In the embodiment, the fabric is folded to form a folded end (the aforementioned edge 91) to which the fastening component 2 is sewn. For example, the auxiliary fabric 93 is overlapped with the main fabric 92 to form a folded end, and at the same time, the fastening component 2 is rotated 90° relative to the loading surface 98 of the article 9. By the rotation of the fastening component 2, the protruding direction of the locking element 30 of the fastening component 2 changes by 90° and is oriented to be orthogonal to the thickness direction of the portion of the fabric other than the folded end (for example, the main fabric 92). To explain more generally, the protruding direction of the locking element 30 changes from an orthogonal state to a parallel state relative to the loading surface 98 of the article 9 (for example, the main fabric 92). In addition, the locking element columns 21 and 22 on both sides of the mounting portion 27 are arranged side by side in the thickness direction of the main fabric 92, and are arranged on both sides of the plane PL0 as described above, so that the same benefits as described above can be obtained (refer to Figure 3 ). In addition, it is also possible to Figure 10 Before the installation process shown Figure 11 The folded end forming process shown in FIG. In this case, the folded end to be sewn to the fastening component 2 is formed by folding the fabric. This method is more suitable for ultrasonic welding. Figure 12 In the embodiment, portions of the fabric (e.g., the main fabric 92 and the auxiliary fabric 93) are sewn together near the side edge 95 of the fabric by sewing thread 200. When the article 9 is an article other than fabric, the fastening member 2 can be attached to the article in a manner different from that described.

[0076] like Figure 13As shown in FIG, as a non-limiting example of an intervening object, the fastening components 2, 2' can also be sewn to the cloth via the intermediate sheet 99. The intermediate sheet 99 can be a thin material such as a cloth or a resin sheet. In this case, it can also be sewn to the cloth. Figure 11 Fold the fabric in the same way.

[0077] Reference Figures 14 to 19 Another structure of the fastening components 2, 2' will be further described. As described above, the zipper 1 comprises left and right fastening components 2, 2' and a slider 8. The left and right fastening components 2, 2' can be engaged and disengaged by moving the slider 8 forward and backward. Typically, the fastening components 2, 2' are attached directly to the article 9, eliminating the need for a woven and / or braided zipper tape, thereby contributing to weight reduction and / or cost reduction.

[0078] The fastening components 2 and 2' include a first locking element row 21 and a second locking element row 22, a mounting portion 27, and a base plate 40. The first locking element row 21 and the second locking element row 22 each include a plurality of locking elements 30 arranged at a predetermined interval. The fastening components 2 and 2' include the first locking element row 21, the mounting portion 27, and the second locking element row 22 in their width direction, but do not have the third locking element row 23 and the fourth locking element row 24 and the guide walls 25 and 26 described above (i.e., a three-row structure, i.e., two rows of the first locking element row 21 and the second locking element row 22 + one row of the mounting portion 27), and are formed to be narrower. As a result, the flexibility of the fastening device 2A is improved when it is installed on the article 9. In addition, although the third locking element row 23 and the fourth locking element row 24 are omitted, the guide walls 25 and 26 can also be omitted.

[0079] One side of the base plate 40 serves as the aforementioned mounting surface 2a, and the engaging elements 30 are arranged so as to rise upwards on the side opposite the mounting surface 2a. A group of engaging elements 30 are connected to a common mounting portion 27 and / or a common base plate 40, ensuring mechanical integrity and strength. Adjacent engaging elements 30 in the longitudinal direction of the fastening components 2 and 2' are connected by a connecting portion 70 that is part of the base plate 40. By making the base plate 40 sufficiently thin (e.g., less than 9 mm, less than 7 mm, or less than 6 mm), sufficient flexibility in the longitudinal direction of the fastening components 2 and 2' can be ensured. Including the base plate 40 in the fastening components 2 and 2' facilitates smooth forming of the fastening components 2 and 2' and / or smooth movement of the slider 8. However, the entire base plate 40 or a portion thereof can be omitted. In some cases, all connecting portions 70 of the base plate 40 are omitted, while in other cases, one or more selected connecting portions 70 of the base plate 40 are omitted. In the former case, the connection between the engaging elements 30 is ensured solely by the mounting portion 27. In the latter case, the connection between the engaging elements 30 is ensured by the mounting portion 27 and one or more selected connecting portions 70. Alternatively, a slit may be formed in the connecting portion 70, or at least a portion of the connecting portion 70 may be punched out to form an opening and / or cutout. Furthermore, guide protrusions 51 and 52 may be provided on the mounting surface 2a. However, if they are formed flat as in the example shown, the structure of the forming die, such as the die wheel, can be simplified.

[0080] The mounting portion 27 is a protrusion extending along the length of the fastening components 2, 2' between the first and second rows of engaging elements 21, 22, and projecting toward the side opposite the mounting surface 2a. The mounting portion 27 is formed on the base plate 40, lower than the engaging elements 30, but has a greater thickness than the base plate 40 (TH27 > TH40). This provides the required strength for sewing the fastening components 2, 2' to the article 9, sufficient thickness to withstand heat fusion, and protection against damage during demolding during the manufacturing process, among other advantages. Optionally, the mounting portion 27 can include a reinforcement member 28, such as a braided cord, twisted cord, or nonwoven fabric sheet, extending along its length. This enhances its mechanical strength and / or the strength of its attachment to the article 9. In particular, when the reinforcement member 28 comprises any one of braided cord, twisted cord, or nonwoven fabric sheet, or any combination thereof, a decrease in strength can be minimized even if a needle pierces the resin portion of the mounting portion 27 during sewing of the fastening components 2, 2'. The reinforcement member 28 does not need to be embedded in the mounting portion 27, and may be fixedly provided in the mounting portion 27. In this case, the reinforcement member 28 appears on the exterior of the fastening members 2, 2' and can be visually recognized.

[0081] Each engaging element 30 included in the first engaging element row 21 and the second engaging element row 22 has two protrusions 32 that protrude in opposite directions along the length of the fastening components 2 and 2'. That is, rather than assigning protrusions 32 protruding in opposite directions and only protruding to one side to the two engaging element rows of the first engaging element row 21 and the third engaging element row 23, the protrusions 32 protruding in both directions are assigned to a single engaging element row. This improves the flexibility of the fastening device 2A without significantly reducing the engagement force between the engaging elements 30 of the fastening components 2 and 2'. Furthermore, the two protrusions 32 include a front protrusion 32a that protrudes forward of the base 31 and a rear protrusion 32b that protrudes rearward of the base 31.

[0082] The locking elements 30 in the first locking element row 21 are arranged at a first spacing, while the locking elements 30 in the second locking element row 22 are arranged at a second spacing. In some cases, the first spacing is equal to the second spacing, and in other cases, they are different. By setting the first spacing and the second spacing to be equal, the difference (or directionality associated therewith) between the first and second locking element rows 21, 22 is eliminated, and / or a good balance is ensured between the first and second locking element rows 21, 22 with respect to a target locking force. Depending on the setting of the first and second spacings, the locking elements 30 in the first and second locking element rows 21, 22 can be at least partially arranged facing each other in the width direction of the fastening components 2, 2'. In the illustrated embodiment, the first and second locking element rows 21, 22 are formed as mirror images. Therefore, the locking elements 30 in the first and second locking element rows 21, 22 are arranged facing each other in the width direction of the fastening components 2, 2', thereby achieving the same benefits as described above.

[0083] Each engaging element 30 of the first engaging element row 21 and the second engaging element row 22 has a flat facing surface 38. The spacing between the facing surfaces 38 is typically consistent with the maximum width W27 of the mounting portion 27, but is not necessarily limited to this. The spacing between the facing surfaces 38 can be appropriately changed according to the thickness of the needle used when sewing the article 9. The facing surfaces 38 are oriented approximately perpendicularly to the plane in which the substrate 40 is located, but can also be tilted. Each engaging element 30 has an opposite surface 39 on the side opposite to the facing surface 38. The opposite surface 39 faces or contacts the upper wing plate 81 or the lower wing plate 82 of the slider 8 when the engaging element 30 enters the slider 8. The opposite surface 39 is a substantially flat surface located on a plane perpendicular to the vertical direction, thereby ensuring smooth sliding of the slider 8.

[0084] The engaging element 30 has a symmetrical tapered shape, for example, comprising a base 41, a neck 42, and a head 43, with the neck 42 tapering. By adopting such a tapered shape, the engaging element 30 can have two protrusions 32 that protrude on opposite sides rather than on one side in the longitudinal direction of the fastening components 2, 2', as described above. The base 41 has a width W41 that gradually decreases toward the head 43. The neck 42 is disposed between the base 41 and the head 43 and has a width W42 that is narrower than both. The head 43 has a width W43 that gradually increases and then gradually decreases as it moves away from the neck 42. Furthermore, the engaging element 30 has a width in the longitudinal direction of the fastening components 2, 2', a width (also referred to as a thickness) in the width direction of the fastening components 2, 2', and a height in the thickness direction of the fastening components 2, 2'.

[0085] The space between adjacent engaging elements 30 in the longitudinal direction of the fastening components 2 and 2' comprises an accommodation space 33. The head 43 of the engaging element 30 of the fastening component 2 is inserted between the necks 42 of the adjacent engaging elements 30 of the fastening component 2'. The base 41 has two side surfaces 41a and 41b that rise from the base plate 40, and the facing surface 38 and the opposite surface 39 are connected by these side surfaces. A gap communicating with the accommodation space 33 is formed between the facing side surfaces 41a and 41b of the adjacent engaging elements 30, thereby ensuring sufficient flexibility of the fastening components 2 and 2'.

[0086] Optionally, the engaging element 30 can include at least two shoulder protrusions 44 on either side of the neck 42 and a receiving groove 45 for receiving the shoulder protrusions 44 of the engaging element 30 to be engaged, thereby providing sufficient resistance to vertical thrust from the zipper 1. When the left and right engaging elements 30 of the left and right fastening components 2 and 2' engage with each other, the shoulder protrusion 44 of one engaging element 30 inserts into the receiving groove 45 of the other engaging element 30, restricting vertical displacement of both engaging elements 30. The receiving groove 45 is recessed into the facing surface 38 by notching the edge of the head 43 and is formed across the entire width of the head 43. The maximum width W44 of the shoulder protrusion 44 is less than half the maximum width W30 of the engaging element 30. This allows the receiving groove 45 to be shallow (in the width direction of the fastening components 2 and 2'), thereby preventing a reduction in the mechanical strength of the head 43.

[0087] Reference Figures 14 to 19 The above-mentioned fastening components 2, 2' can be connected with Figure 9 The same manufacturing method as shown in the fastening part can be manufactured by Figures 10 to 12 The fastening components shown are manufactured using the same installation method, and therefore, repeated descriptions are omitted.

[0088] Based on the above disclosure, those skilled in the art will be able to make various changes to the various features and embodiments. The reference numerals added to the claims are for reference only and should not be used to limit the purpose of interpreting the claims. In the illustrated example, the mounting surface 2a contacts the object 9 in its receiving groove 53 (particularly the bottom surface 53g), but does not contact the object 9 on the guide surfaces 56 and 57. However, as long as a portion of the mounting surface 2a includes an area facing or contacting the object 9, it can be understood as a mounting surface as a whole.
