    "HOLDER ELEMENT"
    Field of the invention [001] The present invention relates to fasteners and, more specifically, to a fastener element.
    Background [002] Conventionally, a fastener element is known that includes a base portion that has a surface and a plurality of locking elements provided vertically on the surface, where the locking elements, when attaching to a subject to be coupled, they are mechanically coupled to the subject to be coupled. Similar to this type of technique, a description is provided, for example, in the publication of unassessed Japanese patent application (PCT Application translation) No. H07-509668A for forming a fastening element by injecting melted material to form the fastening element within a mold of a permanent base portion mold, a destructive removable leg portion mold and a permanent head portion mold and allowing it to solidify in the molds. This fastener element is removed from the mold of the leg portion after being removed from the mold of the base portion and the mold of the head portion.
    Summary of the invention [003] With conventional fastener elements there is a problem in the sense that the production process becomes complicated. At the same time, it is necessary to increase the coupling resistance for when the fastener element and the subject to be coupled are coupled. Therefore, it is desirable to provide a fastening element that can be produced through a simple production process and that can exhibit a higher coupling resistance in relation to a subject to be coupled.
    [004] A fastener according to one aspect of this
    2/28 invention is a fastener element that includes: a base portion having a surface; and a plurality of locking elements provided vertically on the surface, the locking elements being attached to a subject to be coupled so as to mechanically couple to the subject to be coupled; wherein the locking element includes: a rod portion, projecting from the base portion, which has a pair of side faces opposite each other in a first direction and, as seen from the surface, diverge in a second direction orthogonal to the first direction; and a barbed portion provided on each of the two side faces; and, as seen from the surface, the barbed portion provided on at least one of the side faces of the two side faces extends in a direction that intersects the first direction and the second direction.
    [005] In accordance with this aspect of the present invention, the barbed portion provided on the side face that faces the first direction of the rod portion extends, as seen from the surface, in a direction that intersects the first direction and the second direction . As the barbed portions extend having directional components of the first direction and the second direction in this way, the range that can be attached to the subject to be coupled can be expanded. In doing so, the locking with the subject to be coupled becomes easier for each of the locking elements, allowing an increase in the locking elements that lock with the subject to be coupled in the fastener element and thus improving the coupling resistance of the fastener element in general. Additionally, even if the barbed portions have a directional component of the first direction and the second direction, as they extend from the side face opposite the first direction, a sliding mold that moves in the second direction can be used to form the side face. Since the locking element can be produced using a single sliding direction in this way, the production process can be made easier. As described above, the fastener element can be produced in a process of
    3/28 simple production and can increase the coupling resistance in relation to a subject to be coupled.
    [006] In a fastener element according to another aspect of the present invention, a plurality of barbed portions can be provided on at least one side face.
    [007] In the fastener element according to another aspect of the present invention, a recess can be formed on the surface of the barbed portion to secure the subject to be coupled.
    [008] In the fastener element according to another aspect of the present invention, the locking element can be arranged in a reticulated manner as seen from the surface.
    [009] In the fastener element according to another aspect of the present invention, the barbed portion may have a portion that extends more in the second direction than the rod portion.
    [010] In the fastener element according to another aspect of the present invention, each of the barbed portions provided on the two side faces can be provided so as to be symmetrical around the rod portion.
    [011] The present invention can provide a fastening element that has a greater coupling resistance compared to a subject to be coupled and that can be produced through a simple production process.

    Detailed description [026] Modalities of the present invention are described in detail below with reference to the drawings. In the following description, the same element or corresponding elements are given the same reference number and repeated explanations are omitted. Additionally, the terms “X direction”, “Y direction” and “Z direction” are terms of convenience based on the directions illustrated in the drawing.
    [027] As illustrated in Figure 1, a fastener element 10 of this modality is used to fasten, for example, an internal panel of a vehicle and configure a surface fastener of the type with face-to-face locking. The fastening element 10 here is used as a hook element that engages and mechanically engages a subject to be coupled (for example, a loop element 30, as shown in Figure 3) which is one side of the coupling. Note that the loop element 30, which is the subject to be coupled, corresponds to the female side of the surface fastener and is configured having a plurality of loop wires 31, which project from the surface of the base portion so that the loop wires 31 extend in an annular shape and are locked by clinging to the locking elements 12 at the moment of coupling. This type of loop element 30 is affixed to, for example, an element on the side of the vehicle body directly or through a bracket, tape, adhesive or the like.
    [028] The fastener element 10 corresponds to the male side of the surface fastener and is molded in a piece of a resin material. The fastener element 10 is provided with a base portion 11 and a plurality of elements
    6/28 locking 12 provided vertically in the base portion 11.
    [029] The base portion 11 is, for example, in a plate format that has a substantially flattened flat surface 15. This type of base portion 11 is affixed to, for example, an element on one side of an inner panel directly or through bracket, tape, adhesive or similar. In this embodiment, the surface 15 diverges in the X and Y directions. Note that the shape of the base portion 11 is not particularly limited and the surface 15 may also not be perfectly flat and may have a partially elevated section, slope or the like.
    [030] The locking elements 12 are provided so that they are erect from the surface 15 in the Z direction and are arranged in a reticulated way with a predetermined distance, as seen from the surface (as seen in the Z direction). Note that a description of the alignment aspects of the locking elements 12 will be provided below. The locking element 12 is provided with a rod portion 20 extending from the surface 15 in the Z direction and a barbed portion 21, provided at the tip end of the rod portion 20.
    [031] A configuration of the locking elements 12 will be described in detail with reference to Figures 2 to 4. The locking element 12 is a portion formed by injection molding, using a sliding mold that moves in the Y direction and a second mold which moves relatively in the Z direction in relation to the locking element 12. Of the shapes of the locking element 12, the external shape (shape shown in Figure 2), as seen in the Z direction, and the shape of the upper side region (of the formats illustrated in Figures 3 and 4, the shape of the region that can be identified by viewing from above, that is, the shape of the region identifiable in Figure 2) is formed by the second mold. Of the shapes of the locking element 12, the region of the lower end, that is, the shape of the recessed portion UE (the region drawn in Figure 4) more submerged
    7/28 internal side that the external shape, as seen in the Z direction, is formed only by the sliding mold that moves in one direction. Note that the region traced in Figure 3 illustrates a submerged SE portion inside the inner side, as seen in the X direction, and the submerged SE portion is a part of a region of the lowered EU portion (in Figure 3, the lowered EU portion is not completely traced, only the submerged SE portion is traced to facilitate understanding). The submerged portion SE is formed at the same time as the lowered portion UE is formed only by the sliding mold that moves in one direction. Note that in the following description, a virtual plane orthogonal to the Y direction will be called a “CP1 reference plane” and a virtual plane orthogonal to the X direction will be called a “CP2 reference plane.” Additionally, the X direction will correspond to the “first direction” described in the aspect and the Y direction will be the “second direction” given in the aspect.
    [032] The stem portion 20 is a substantially rectangular columnar element that projects in a direction orthogonal to the surface 15 (direction Z) from the surface 15. The stem 20 has a plane-symmetrical configuration across the plane of reference CP1, as seen in the X direction, and has a plane-symmetrical configuration through the reference plane CP2, as seen in the Y direction. In other words, the reference plane CP1 becomes a central plane, as seen in the X direction ( direction shown in Figure 3) of the stem portion 20, and the reference plane CP2 becomes a central plane, as seen in the Y direction (direction shown in Figure 4). The dimensions in the X direction and in the Y direction of the stem portion 20 are set to approximately 0.2 to approximately 2.0 mm or to approximately 0.4 to approximately 1.2 mm, and the dimensions in the Z direction are configured from approximately 0.7 to approximately 3.0 mm or from approximately 1.2 to approximately 2.3 mm.
    [033] The stem portion 20, as seen in the Z direction, has a pair of faces
    8/28 side 22A and 22B that are opposite each other in the X direction and that diverge in the Y direction (see Figure 2). In this embodiment, the side faces 22A and 22B are formed by planes that diverge so that they become parallel in the Y direction, as seen in the Z direction. The side faces 22A and 22B have an end region of the base 22a that becomes a plane parallel to the reference plane CP2 on the surface side 15 and a tip end region 22b which makes a plane parallel to the reference plane CP2 on the tip end side. The end region of the tip 22b is more outwardly relative to the reference plane CP2 than the end region of the base 22a.
    [034] The end region of the base 22a is a region on the side faces 22A and 22B formed by the sliding mold at the time of molding. The tip end region 22b is a region on the side faces 22A and 22B formed by the second mold at the time of molding. Note that, in this embodiment, as the barbed portions 21 are formed substantially throughout the region of the tip end region 22b, the side faces 22A and 22B in the tip end region 22b become virtual planes in a boundary portion between the portion shank 20 and the barbed portion 21. As long as the side faces 22A and 22B can be formed by a molding method using the sliding mold and the second mold (detailed description provided below), they can be formed in any shape. For example, the base end region 22a and the tip end region 22b can be formed in the same plane. For example, the side faces 22A and 22B in the end region of the base 22a can be in a flat or curved plane that slopes in a tapered shape, as seen in the Y direction (direction shown in Figure 4). Additionally, for example, the side faces 22A and 22B in the tip end region 22b may have a shape that curves outwards or inwards, as seen in the Z direction (direction shown in Figure 2).
    9/28 [035] The stem portion 20, as seen in the Z direction, has a pair of side faces 23A and 23B that are opposite each other in the Y direction and that diverge in the X direction (see Figure 2). In this embodiment, the side faces 23A and 23B are formed by planes that become parallel in the X direction, as seen in the Z direction, and by planes that become almost parallel in the Z direction. The side faces 23A and 23B are portions formed by the second mold at the time of molding. As long as the side faces 23A and 23B can be formed by the second mold, they can be formed in any shape. For example, side faces 23A and 23B may have a shape that curves outwards or inwards, as seen in the Z direction (direction shown in Figure 2).
    [036] The stem portion 20 has a face of the tip end 24 which opposes surface 15 and which extends in the XY direction. In this embodiment, the face of the tip end 24 extends to be parallel to the surface 15. The face of the end of the side tip 24 is a portion formed by the second mold at the time of molding. As long as the end face of the tip 24 can be formed by the second mold, it can be formed in any shape and a modified example will be described in detail below.
    [037] The barbed portion 21 is formed on each of the two side faces 22A and 22B, which face each other in the X direction. The barbed portion 21 extends in a direction that intersects the X direction and the Y direction , as seen in the Z direction. In other words, the direction of extension of the barbed portion 21 is not configured from a directional component of only one of the X direction component and the Y direction component, but is configured from directional component of the component the X direction and the Y direction component. Additionally, the barbed portion 21 extends to extend outwardly from the rod portion 20 as it approaches surface 15, as seen in the Y direction. The barbed portion 21 extends downwards to the outside from the end region
    10/28 of the tip 22b of the side faces 22A and 22B, forming a strip. In addition, during the formation of the recessed portion EU below the barbed portion 21, a space is formed between a portion on one side of the lower end (surface side 15) of the barbed portion 21 and the surface 15 of the base portion 11. When the loop wire 31 of the loop element 30 is inserted into the space, it attaches to the barbed portion 21 and is locked. In addition, barbed portions 21 are provided in a plurality on each of the side faces 22A and 22B. In this embodiment, barbed portions 21A and 21B are formed on the side face 22A and barbed portions 21C and 21D are formed on the side face 22B, so that four barbed portions 21 are formed in a locking element 12.
    [038] First, with respect to Figure 2, a configuration of the barbed portions 21, as seen in the Z direction, will be described. Note that, as shown in Figure 2, to describe the configuration of the barbed portions 21A to 21 D, SLA to SLD axis lines are established in relation to the barbed portions 21A to 21 D, as seen in the Z direction. The SLA axis lines the SLD are lines that extend in the direction of extension of the barbed portions 21A to 21D and are defined by a central position in the width W of the barbed portions 21A to 21 D.
    [039] The barbed portion 21A is provided in a region on the side of the side face 23A (a region of the upper right surface of the paper in Figure 2) on the side face 22A of the rod portion 20. The barbed portion 21A extends towards the outer side in the X direction, from the side face 22A, so as to retract from the reference plane CP1 towards the outer side in the Y direction. Specifically, the starting point P1 of the SLA axis line of the barbed portion 21A is placed in a substantially central position between the reference plane CP1 and the side face 23A, of the side face 22A, and the axis line SLA is configured so that it extends from the starting point P1 in a direction that tilts in a predetermined angle Θ with respect to the reference plane
    11/28
    CP1. In this embodiment, the predetermined angle Θ is set to 45 °, but the angle can be set to any angle within a range of approximately 0 to approximately the 65 ° or approximately 35 ° to approximately 53 °.
    [040] The side faces 21b and 21c in the width direction of the barbed portion 21A extend along the SLA axis line. In other words, the side faces 21b and 21c extend towards the outside in the X direction, so that they retract from the reference plane CP1 towards the outside in the Y direction. Note that the side faces 21b and 21c become substantially parallel in the Z direction (there is a slight slope in the Z direction, as a draft is required). Specifically, the starting point P2 of the side face 21b on the outer side in the Y direction is configured in a corner portion between the side face 22A and the side face 23A and the side face 21 b extends from the starting point P2, so as to become parallel to the SLA axis line. Note that, as the predetermined angle Θ is 45 °, the side face 21b is arranged diagonally from the stem portion 20. Additionally, the starting point P3 of the side face 21c on the inner side in the Y direction is set in a position central (in reference plane CP1) in the Y direction of the side face 22A and the side face 21c extends from the starting point P2 so as to be parallel to the axis line SLA. The width width dimension W of the barbed portion 21A is set at approximately 0.2 to approximately 1.0 mm or from approximately 0.2 to approximately 0.5 mm. The final portion 21 d of the barbed portion 21A becomes parallel to the Y direction. However, the shape of the final portion 21 d is not limited and modified examples will be described below. The protrusion length (in this case a distance between the side face 22A and the final portion 21 d) in the X direction of the barbed portion 21A is set to approximately 0.2 to approximately 1.0 mm or approximately 0.2 to approximately 0.5 mm.
    12/28 [041] According to the configuration as the configuration described above, the barbed portion 21A has a portion that extends more in the Y direction than the rod portion 20, as seen in the Z direction. In other words, the portion barbed wire 21A has a portion that extends more outwardly in the Y direction than the side face 23A of the rod portion 20. Additionally, in a region on the underside of such a portion, the submerged portion SE is formed submerged within the inner side , as seen in the X direction (see Figure 3). As a portion (or even all) of the final portion 21 d of the barbed portion 21A is arranged more outwardly in the Y direction than the side face 23A of the stem portion 20, the loop wire 31 of the loop element 30, which exists more outwardly in the Y direction than the rod element 20, can also be secured by the barbed portion 21A (see Figure 3).
    [042] Note that, to facilitate fixation in the molding, the starting point P2 of the side face 21b is configured in the corner portion of the stem portion 20, but the determined position is not particularly limited and it can be configured in one position on the inner side in the Y direction of the side face 22A, it can be configured in a position more outward in the Y direction than the side face 22A (for example, the starting point P2 'illustrated in Figure 2) or can be configured in a position close to the corner portion on the side face 23A (for example, the starting point P2 illustrated in Figure 2). In addition, the starting point P3 of the side face 21c can also be configured in any of the positions of the side face 22A or can be configured in a position that intercepts a barbed portion 21B adjacent to the barbed portion 21A (for example, the starting point P3 'illustrated in Figure 2). In addition, the side faces 21 b and 21 c extend parallel to the SLA axis line, but they can extend widely in width towards the outside in the X direction or they can extend in order to narrow. Extending the width within a strip that does not compromise the ease of locking with the loop wire 31 of the loop element 30 allows to guarantee the resistance of the end of the end of the barbed portion
    13/28
    A. Narrowing within a band that guarantees resistance improves the ease of locking between the barbed portion 21A and the loop wire 31 of the loop element 30. Note that the shape of the barbed portion 21, as seen in the Z direction, can be any shape that can be formed by the second mold and a modified example will be described in detail below.
    [043] On the side face 22A, the barbed portion 21B in an adjacent position in the Y direction to the barbed portion 21A has a flat-symmetrical configuration with the barbed portion 21A in relation to the CP1 reference plane. Through this, in the region on the side of the side face 23B on the side face 22A of the rod portion 20 (region in the lower right corner of the paper surface in Figure 2), the barbed portion 21B extends from the side face 22A towards the side outer in the X direction so as to retract from the reference plane CP1 to the outer side in the Y direction. However, the barbed portion 21A and the barbed portion 21B do not require flat symmetry and can be made in different shapes from each other.
    [044] The barbed portions 21C and 21 D, provided on the side face 22B, are provided so as to be symmetrical with respect to the barbed portions 21A and 21B around the rod portion 20. In other words, the barbed portions 21C and 21D they have a symmetrical-flat configuration with the barbed portions 21A and 21B in relation to the CP2 reference plane. Thus, in the region on the side of the side face 23A, on the side face 22B of the rod portion 20 (the region in the upper left corner of the paper surface in Figure 2), the barbed portion 21C extends from the side face 22B towards external side in the X direction, so as to retract from the reference plane CP1 to the external side in the Y direction. In the region of the side face 23B, in the side face 22B of the stem portion 20 (the region in the upper left corner of the surface of the paper in Figure 2), the barbed portion 21D extends from the side face 22B towards the outside in the X direction, so as to retract from the reference plane CP1 to the outside in the Y direction. However, the barbed portions 21A
    14/28 and 21B and the barbed portions 21C and 21D do not require flat symmetry and can be made in different formats.
    [045] Next, with reference to Figure 4, a configuration of the barbed portions 21A to 21 D, as seen in the Y direction, will be described. As shown in Figure 4, the barbed portion 21A is attached to the rod portion 20 in the tip end region 22b of the side face 22A. The barbed portion 21A extends to the side of the surface 15, so as to tilt in relation to the Z direction, and extends, so as to retract from the side face 22A of the rod portion 20, approaching the surface 15. A sloping face 21a on the outer side of the barbed portion 21A extends from the face on the end end of the tip 24 of the shank portion 20 towards the side of the surface 15 so as to retract from the side face 22A of the shank portion 20. A inclined face 21a diverges parallel in the Y direction and is configured by an inclined plane in this mode. Specifically, the inclined face 21a has a starting point P4, configured in a corner portion between the face of the tip end 24 and the lateral face 22, and extends directly to the side of the surface 15, in order to incline towards the outer side in the X direction from the starting point P4. The dimension in the Z direction of the barbed portion 21 A, that is, the dimension in the Z direction between the top end of the sloped face 21a (here being the same position as the face of the tip end 24) and the final portion 21 d of the bottom side of the sloping face 21a is set to approximately 0.3 to approximately 2.0 mm or approximately 0.5 to approximately 1.5 mm. Note that the shape of the inclined face 21a, as seen in the Y direction, can be any shape that can be shaped by the second mold and can include a shape that curves outwardly or inwardly. In addition, the starting point P4 can also be formed at any position in the tip end region 22b of the side face 22. In addition, an R shape can be formed between the inclined face 21 a and the face of the tip end 24.
    [046] A recess 26 for securing the loop wire 31 of the loop element 30
    15/28 is formed on the surface side 15 of the barbed portion 21 A. The recess 26 is configured by a groove that extends parallel in the Y direction in a predetermined shape with respect to the region on the underside of the surface side of the barbed portion 21 A. The recess 26 is a part of the recessed portion EU formed by the sliding mold that moves in the Y direction. In this embodiment, a face of the lower end 21 and extends to the side face 22A of the stem portion 20, from the end portion 21 d of the inclined face 21a, and the recess 26 is formed with respect to the face of the lower end 21 e. The recess 26 is configured from the side face 22A in the base end region 22a of the stem portion 20, an inclined face 26a facing the inclined face 21a on the outside, and a connected face 26b where the upper end portion of the inclined face 26a and the side face 22A connect.
    [047] The inclined face 26a is formed to be substantially parallel to the inclined face 21a on the outside and the lower end portions of both inclined faces 21a and 26a are connected by the face of the lower end 21 e. Therefore, a portion of the claw 27 that has a thinner thickness compared to the portion corresponding to the tip end region 22b is formed on the tip end side of the barbed portion 21 A. The formation of the claw portion 27 allows the the loop wire of the loop element 30 is more easily secured by the recess 26 of the barbed portion 21 A. The thickness T of the clip portion 27 is set to approximately 0.15 to approximately 0.4 mm. The dimension in the Z direction of the portion of the claw 27, i.e., the dimension in the Z direction between a connected face 26b and the face of the lower end 21 e, is set to approximately 0.1 to approximately 0.8 mm. Note that the face of the lower end 21 e and the connected face 26b become flat parallel to the surface 15. With the setting of the claw portion 27 to such a dimension, the loop wire of the loop element 30 can be easily attached, as well as ensuring
    16/28 enough strength.
    [048] Note that, as the lower end region (the face of the lower end 21, the sloping face 26a and the connected face 26b) of the barbed portion 21A is formed by the sliding mold at the time of molding, the shape can be any shape that can be shaped by the sliding mold and a modified example will be presented in detail later in this document.
    [049] The barbed portion 21B, as described above, becomes a flat-symmetrical configuration with the barbed portion 21A in relation to the CP1 reference plane. Additionally, the barbed portions 21C and 21 D, provided on the side face 22B, are provided to be symmetrical to the barbed portions 21A and 21B around the rod portion 20 to create a flat-symmetrical configuration with the barbed portions 21A and 21B , in relation to the CP2 reference plane. Consequently, the barbed portion 21B, as seen in the Y direction, takes the same shape as the barbed portion 21A and the barbed portions 21C and 21D assume a plane-symmetrical shape in relation to the reference plane CP 2 with the barbed portions 21A and 21B. Additionally, the barbed portion 21C, as seen in the X direction, takes the same shape as the barbed portion 21A and the barbed portion 21D takes the same shape as the barbed portion 21B (see Figure 3). Note that, as described above, barbed portion 21A and barbed portion 21B do not require flat symmetry and can be made in different formats. Additionally, the barbed portion 21A and the barbed portion 21C do not require flat symmetry and can be made in different shapes from each other. In addition, the barbed portion 21B and the barbed portion 21D do not require flat symmetry and can be made in different formats.
    [050] The fastener element 10, according to this modality, is produced using a predetermined mold structure. The fastener element 10 is produced by injection molding, using a first mold
    17/28 forming a shape of the upper side in the Z direction, a second mold forming a shape of a lower side in the Z direction and a sliding mold. The sliding mold is used to form the recessed portion EU of the barbed portion 21 of the locking element 12 and can slide in the Y direction.
    [051] The combination of the first mold, the second mold and the sliding mold, as described above, allows the creation of an internal space that corresponds to the shape of the fastening element 10 to be formed, as well as the injection of resin into the interior of the internal space. For example, applicable resins include polyester based, polyolefin based, polyamide based, polyurethane based, polyether based, acrylic based, polycarbonate based and styrene based resins. After the resin has cooled and solidified, the first mold is moved in the Z direction (or the second mold is moved in the Z direction) and the slide mold is moved in the Y direction to release the slide mold. This allows removal of the molded fastener 10.
    [052] As described above, a sliding mold that moves in a plurality of directions is not necessary and molding is possible using only a sliding mold that moves in one direction. Since the locking elements 12 cannot be formed in a position where the sliding mold passes through, the molding positions of the locking elements 12 are restricted when a multidirectional sliding mold is used, but in this embodiment, as only a sliding mold is used unidirectional, the molding positions of the locking elements 12 are not restricted and they can be formed in high density.
    [053] Next, a matrix configuration of the locking elements 12 will be described with reference to Figures 5 and 6. With the fastening element 10 according to the modality described above, the locking elements 12 can be formed in high density in the base portion 11.
    18/28
    Therefore, as shown in Figures 5 and 6, it is possible that the locking elements 12 are arranged in a reticulated manner, as seen in the Z direction. The sizes (dimensions indicated by L1 and L2 in the extraction) on each side of the base portion 11 , shown in Figures 5 and 6, are configured to be approximately 5 to approximately 400 mm (the length can be as long as desired, as long as it fits in the mold). Note that here L1 and L2 have the same dimensions, but different dimensions are also possible.
    [054] In the example shown in Figure 5, each side of the base portion 11 is parallel to the X direction or the Y direction. The locking elements 12 are arranged so as to form a linear row at constant spacing in the Y direction and a plurality of rows are aligned at a constant spacing in the X direction. Additionally, the positions in the Y direction of the locking elements 12 associated with a row and the locking elements 12 associated with an adjacent row are arranged so as to be misaligned with each other. Consequently, the locking elements 12 are configured to be arranged in an offset shape in the X direction. As many locking elements 12 as possible in relation to the size L1 are arranged on the side of the base portion 11 in the Y direction, and as many locking elements 12 as far as possible are arranged in relation to the size L2 on the side of the base portion 11 in the X direction. In other words, a plurality of locking elements 12 are arranged from a first portion of the surface edge 15 of the base portion 11 until you reach a second portion of the opposite edge. Therefore, the locking elements 12 are formed over the entire surface region 15 of the base portion 11 in said pattern. The spacing between each row (dimensions indicated by P1 in the drawing) is set to approximately 1.0 to approximately 3.0 mm (the length can be up to a size that fits the mold). In addition, the spacing of the locking elements 12 in each row (dimension indicated by P2 in the drawing) is set to approximately 1.0 to
    19/28 approximately 3.0 mm (the length can be up to a size that fits the mold). Note that the width of the misaligned arrangement in the X direction (dimension indicated by P3 in the drawing) can be set to half the spacing (P2 / 2) of the locking elements 12 for each row.
    [055] In the example shown in Figure 6, each side of the base portion 11 is inclined 45 ° with respect to the X direction or the Y direction. The locking elements 12 are arranged to form a linear row at constant spacing in the direction Y (a first diagonal direction of the base portion 11), and several rows are aligned at constant spacing in the X direction (a second diagonal direction of the base portion 11). Note that the positions in the Y direction for the locking elements 12 associated with a row and the locking elements 12 associated with an adjacent row are arranged to correspond. Consequently, the locking elements 12 are configured to be arranged in a linear shape in the X direction. As each side of the base portion 11 is inclined by 45 ° with respect to the XY direction, the number of locking elements 12 in each row differs depending on the position in the X direction. In each row, as many locking elements 12 as possible are arranged in relation to the size in the first diagonal direction of the base element 11. In other words, a plurality of locking elements 12 is arranged to from the first edge portion of the surface 15 of the base portion 11 to the second edge portion opposite in the diagonal direction. Therefore, the locking elements 12 are formed over the entire surface region 15 of the base portion 11 in said pattern. The spacing between the rows (dimensions indicated by P1 in the drawing) and the spacing of the locking elements 12 per row (dimensions indicated by P2 in the drawing) can be configured to be equivalent to the dimensions given in the example in Figure 5.
    20/28 [056] Note that the arrangement of the locking elements 12 is not limited to the example described above and all the arrangements that can be formed are possible as long as the locking elements 12 are outside the regions where the sliding mold moves in the Y direction it crosses.
    [057] Next, the action and effect of the fastening element 10, according to this modality, will be described.
    [058] First, a fastening element according to a comparative example will be described with reference to Figures 7 to 9. Locking elements 212 of the fastening element shown in Figure 7 are provided with barbed portions 221 that extend only in the X direction from the side face 222 that opposes the X direction of the rod portion 220. The barbed portion 221 of this type of locking element 212 can be formed by a sliding mold 210 that moves in the Y direction. With this type of locking element 212 , the loop wire 31 of the loop element 30, which is the subject to be coupled, if residing in an adjacent position in the X direction with respect to the locking element 212, can be secured by a barbed portion 221, but, if resident in a misaligned position in the Y direction with respect to the rod portion 220, it cannot be secured by a barbed portion 221. Furthermore, as the barbed portion 221 extends only in the X direction, the loop wire 31 may not be sufficiently secured depending on the orientation of the loop wire 31 of the loop element 30.
    [059] Next, a locking element 312 of the fastening element 310, shown in Figures 8 and 9, is provided with, as shown in Figure 8A, a barbed portion 321 that extends only in the X direction, from the side face 322 that opposes the X direction of the rod portion 320 and a barbed portion 321 that extends only in the Y direction, from the side face 323 that opposes the Y direction. With this, the strip that allows the loop wire 31 of the loop element 30 to be secured can be enlarged, but the following problems arise in this configuration.
    21/28
    Specifically, as shown in Figure 8B, to form the recessed portion in relation to the barbed portion 321, which extends in the X direction, and the recessed portion in relation to the barbed portion 321, which extends in the Y direction, sliding molds are required to two directions. For example, a slide mold 350, which moves in the Y direction, is needed for the barbed portion 321, which extends in the Y direction, and a slide mold 360, which moves in the X direction, is required for a barbed portion 321 , which extends in the X direction. When this type of method is adopted, production costs increase. In addition, since locking elements 321 cannot be arranged in positions where sliding molds 350 and 360 pass, the high density molding of locking elements 312 is affected.
    [060] Alternatively, in the method illustrated in Figure 9, the recessed portion of the barbed portion 321, which extends in the X direction, uses a sliding mold 301 that slides in the Y direction and the recessed portion of the barbed portion 321, which extends in the Y direction, uses a 304 mold that pushes from the bottom up. When this type of method is adopted, as illustrated in Figures 9A and 9B, it is necessary to form through holes 311a in the base portion 311 itself for the mold 304 to pass through. The formation of through holes 311a reduces the adhesive force with other elements on the side of the rear surface (functions as an adhesive surface with other elements) of the base portion 311 and also reduces the stiffness of the fastener. In addition, the high density formation of the locking elements 312 is also affected by ensuring space for the through holes 311a to avoid getting too close to the through holes 311a.
    [061] At the same time, with the fastener element 10 according to this modality, the barbed portions 21 provided on the side faces 22A and 22B, which oppose in the X direction of the rod portion 20, extend in directions that intersect the direction X and the Y direction, as seen in the Z direction. Thus, as the component
    22/28 of the X direction and the Y direction component are included in the directions that the barbed portions 21 extend, the strip over which the loop wire 31 of the loop element 30 can be attached can be enlarged compared to the elements of locking 212 illustrated in Figure 7. In this way, it is easier for each individual locking element to attach to the loop wire 31 and how the locking elements 12 that lock with the loop wire 31 on the locking element 10 can be increased, the resistance of coupling with the loop element 30 to the fastener element 10 in general can be increased. Additionally, since the barbed portions 21 have directional components of the X direction and the Y direction, the coupling can be safely performed regardless of the orientation of the loop wire 31 of the loop element 30.
    [062] Additionally, even if the barbed portions 21 have a directional component of the X direction and the Y direction, as it extends from the side faces 22A and 22B opposite the X direction, a sliding mold that moves in the Y direction can be used to form side faces 22A and 22B (side faces 22A and 22B at the base end region 22a) at the same time. Thus, a multidirectional sliding mold is not necessary and, using only a sliding mold that moves in the Y direction, the recessed portion UE can be formed having a submerged portion in relation to the inner side, as seen in the Y direction ( direction shown in Figure 4) in relation to the barbed portions 21, as well as a submerged SE portion more submerged to the inner side, as seen in the X direction (state shown in Figure 3) at the same time. As production is possible with only one direction of sliding in this way, the production process can be facilitated, production costs can be reduced and the production speed can be increased. In addition, as a multidirectional sliding mold and / or through holes in the base portion 11, necessary in the production of the locking elements 312 illustrated in Figures 8 and 9, are not necessary,
    23/28 there may be fewer restrictions on the arrangement of the locking elements 12 and the locking elements 12 can be arranged in high density on the surface 15 of the base portion 11. Therefore, the coupling resistance to the loop element 30 can be increased further.
    [063] Additionally, since simple injection molding can be adopted using only a unidirectional sliding mold, instead of any other complex modeling method to produce this type of high performance fastener 10, production costs can be lower. As described above, the fastening element 10 can be produced through a simple production process and can increase the coupling resistance with a subject to be coupled.
    [064] Additionally, with the fastener element 10 according to this embodiment, the barbed portions 21 can be provided in a plurality on the side faces 22A and 22B. Increasing the barbed portions 21 that have directional components of the X direction and the Y direction in this way allows to further improve the coupling resistance of the loop element 30.
    [065] Additionally, in the fastener element 10 according to this embodiment, the recess 26 for securing the loop wire 31 of the loop element 30 is provided on the surface side 15 of the barbed portions 21. With this, the loop wire 31 of the loop element 30 attaches easily to the barbed portions 21 and can be held firmly even after it has been secured. With this, the coupling resistance can be further increased.
    [066] Additionally, in the fastener element 10 according to this modality, the locking elements 12 are arranged in a reticulated manner, as seen in the Z direction. With this, the locking elements 12 can be arranged in high density on the surface 15 of the base portion 11 and the coupling resistance with the loop element 30 can be further increased.
    24/28 [067] Additionally, in the fastener element 10 according to this modality, the barbed portions 21 have a portion that extends further in the Y direction than the rod portion 20, as seen in the Z direction. loop wire 31 that resides on the outside of the stem portion 20 in the Y direction can be secured.
    [068] Additionally, in the fastener element 10 according to this modality, each of the barbed portions 21, provided in the pair of side faces 22A and 22B, is provided in order to be symmetrical around the rod portion 20. With this, the loop wire 31 which resides on the side face 22A, as well as the loop wire 31 which resides on the side face 22B can similarly attach to the barbed portions 21. Therefore, a stable coupling resistance can be improved.
    [069] Descriptions of favorable modalities of the present invention are provided above, however, the present invention is not limited to the modalities described above and can be modified or applied to other applications within a scope that does not alter the elements described in the claims.
    [070] The shape of the barbed portions, as seen in the Z direction, can be configured in any way, as long as they can be formed by the mold. For example, the direction the barbed portions extend does not have to be linear, but they can also extend in a curved shape, as long as the directional components of the X direction and the Y direction are included. For example, in the locking element 40 shown in Figure 10A, the barbed portions 41 extend in a curved shape from the side faces 22A and 22B of the rod portion 20 towards the outside of the rod portion 20. Thus, both faces of the ends of the barbed portions 41 have a curved surface that curves outwards.
    [071] Additionally, the shape of the final portion of the barbed portion is also not
    25/28 must have a straight shape in the Y direction, as described in the modality above, but any shape can be used. For example, in the locking elements 50, shown in Figure 10B, the end portions of the barbed portions 51 are rounded to form an R shape. Additionally, in the locking element 60, shown in Figure 10C, the final portions are formatted in a way to be orthogonal to the direction that the barbed portions 61 extend.
    [072] Furthermore, the number of barbed portions 21 formed on the side faces 22A and 22B is not particularly limited and three or more barbed portions 21 can be provided or only a barbed portion 21 can be provided. Note that when a plurality of barbed portions 21 are provided, a portion of the barbed portions may include only the directional component in the X direction. For example, in the locking element 70, shown in Figure 10D, three or more barbed portions 71 and 72 are formed on the side faces 22A and 22B. In addition, the locking element 70 also has the barbed portion 72 which includes only the directional component in the X direction, in addition to the barbed portion 71 which includes the directional components of the X direction and the Y direction. Note that a barbed portion 71 and a barbed portion 72 is in a coupled state close to the side faces 22A and 22B. Additionally, in the locking element 80, shown in Figure 10E, three barbed portions 81 and 82 are formed on the side faces 22A and 22B. In addition, the locking element 80 also has the barbed portion 82 which includes only the directional component in the X direction, in addition to the barbed portion 81 which includes the directional components of the X direction and the Y direction. Note that a pair of barbed portions 81 and a barbed portion 82 are in a coupled state close to side faces 22A and 22B.
    [073] Additionally, the shape of the end side of the end of the locking element can be configured in any way, as long as it can be
    26/28 be formed by the mold. For example, in the locking element 170, shown in Figure 11A, the formation of a large R-shape between the rod portion 172 and the barbed portion 171, allows the tip end portion 173 to be rounded. Additionally, in the locking element 180, shown in Figure 11B, the extension of the inclined faces on the outside of the barbed portion 181, as they are, and the joint at the tip end make the tip end portion 183 shaped. pointed without the stem portion 182 having a flat end end face.
    [074] Additionally, the recess formed in the recessed portion of the barbed portion can be configured in any way, as long as it can be formed by the sliding mold. For example, in the locking element 130, shown in Figure 11C, a rounded recess 134 is formed in relation to the barbed portion 131. Additionally, in the locking element 140, shown in Figure 11 D, a recess 144 is formed so that all the recessed portion of the barbed portion 141 becomes an inclined face. Additionally, in the locking element 150, shown in Figure 11E, a recess 154 is formed so that the entire region close to the rod portion 152 becomes an inclined face of the recessed portion of the barbed portion 151.
    [075] Any size, width or shape for a barbed portion can be determined, as long as it can be formed by the mold, but provide a small width and / or thickness per individual barbed portion and form as many as possible on the side face of the The rod portion is effective because the loop wire becomes easier to attach. Whereas the barbed portion is configured to be of sufficient width and thickness to ensure the strength necessary to hold the fastened loop element. Note that when worshiping a material that has high strength for the barbed portion, a rod-like element provided in the rod portion 162, such as the locking element 160 illustrated in Figure
    27/28
    11F, can be used as the barbed portion 161.
    [076] Additionally, the shape of the side face of the stem portion is also not particularly limited. For example, in the locking element 190, shown in Figure 12, the side faces 193A and 193B of the stem portion 192 are angled with respect to the reference plane CP2 in the tip end region 22b. In addition, the tip end region 22b is more inwardly relative to the reference plane CP2 than the base end region 22a.
    [077] Note that, of the side faces that oppose the X direction of the rod portion, only any of the side faces can have barbed portions that extend in directions that intersect the X direction and the Y direction. Additionally, the plurality of locking elements of the fastening element, only a portion of the locking elements can have barbed portions that extend in directions that intersect the X direction and the Y direction.
    [078] Additionally, in the above embodiment, the fastener element 10 is intended for the interior of a vehicle, but the use of the fastener element 10 is not limited. The fastening element 10 can be applied to the coupling in several fields and can be supplied for use, for example, in the fixing of other elements such as seats of a vehicle, in the fixing of construction materials, in the fixing of a doormat, in the fixing of a fabric to a chair, to hold a curtain, to attach showcase items such as a display panel, to attach a support and to attach nursing care equipment.
    [079] Additionally, the fastener element of the above modality is coupled to a loop element 30 as the subject to be coupled, but the subject to be coupled is not limited. The subject to be coupled with the fastening element 10 can be, for example, another loop element other than the loop element 30 or it can be a hook element that has a structure similar to that of the element
    28/28 fastener 10.
