FIG. 11 is a schematic view showing a state in which the claw portions at the front ends of the left and right flange portions of the wing body of the fastener slider are locked to the fastener element.

  As shown in FIG. 1, the fastener slider 10 is an assembly-type fastener slider configured by assembling three types of parts. Components of the fastener slider 10 are a wing body 100, a frame body 200, and a handle 300. When the handle 300 is omitted, the fastener slider 10 is configured by assembling two types of parts. The handle 300 is only an optional component.

  The wing body 100 includes an upper wing plate 110 and a lower wing plate 120 separately provided on the upper wing plate 110, and the upper wing plate 110 and the lower wing plate 120 are arranged in the vertical direction. It is a component in which a moving path for the left and right fastener elements 30 is provided between the plates 120. The movement path of the left and right fastener elements 30 is defined from above and below by the upper wing plate 110 and the lower wing plate 120, branched by a pillar portion 130 described later, and is defined from the left and right by left and right flange portions 140, and is generally Y-shaped. Configured. The wing body 100 includes an independent non-integrated upper wing plate 110 and a lower wing plate 120 as shown in the figure, but also includes a form in which the upper wing plate 110 and the lower wing plate 120 are integrated as will be described later. To do.

  The frame body 200 is a component that can be inserted into the wing body 100 and can support the wing body 100 from above and below. After the wing body 100 is inserted, the frame body 200 accommodates the wing body 100 and holds it in the frame. The wing body 100 is inserted into the frame body 200 from its front end, but the manner of inserting the wing body 100 into the frame body 200 is arbitrary and should not be limited to the disclosed embodiment. With the upper wing plate 110 and the lower wing plate 120 fully inserted into the frame body 200, the front end of the fastener slider 10 has two left and right front ports, and the rear end has one rear port. Is done.

  The pull handle 300 has a base end 301 and a free end 302, an opening 310 is provided on the base end 301 side, and a U-shaped bar portion 320 is provided around the opening. The specific configuration of the puller 300 is arbitrary, and various other types of pullers can be employed.

  The wing body 100, the frame body 200, and the handle 300 are preferably manufactured by molding a resin material, and the size of the fastener slider 10 manufactured by assembling these is not limited and illustratively, The front-rear length is 5-10 cm, the left-right width is 3-7 cm, and the vertical height is 1-3 cm. When the size of the fastener slider is increased, voids (bubbles) are generated in the resin when the temperature of the filled resin in the mold is lowered, and the outer shape is likely to be deformed due to contraction when the resin is cooled.

  In this embodiment, in view of this point, the resin fastener slider is constructed in an assembling manner. In this case, it is possible to obtain a resin fastener slider having a large size as a whole while avoiding the problems of voids and deformation by individually molding each component. Furthermore, individual component parts are manufactured by a relatively simple mold apparatus instead of a relatively complicated mold apparatus used in the manufacture of conventional non-assembled resin fastener sliders. You can also Due to the simplification of the structure of the mold for molding, as will be described later, a structure that is not practically realized with a mold apparatus for a non-assembly type resin fastener slider, it is basically shown in FIG. A claw portion 145 of a flange portion 140 to be described later can also be provided to the wing body 100.

  In addition, you may comprise each component of the fastener slider 10 with materials other than resin. For example, you may manufacture each component with other materials, such as a metal and a fiber reinforced composite material. In an exemplary embodiment, the frame body 200 is made of metal, and the other is made of resin. In an exemplary embodiment, the frame body 200 is made of resin, and the other is made of metal. Note that “resin” is not limited to a single type of resin, and two or more types of resins may be employed. In addition, when employ | adopting metal components, it is assumed that mechanical processes, such as a press work, a bending process, a cutting process, and a punching process, are utilized. When the component is made of resin, a general-purpose mold forming technique can be utilized.

  As can be understood from the reference to FIG. 1, FIG. 2, and FIG. 10, the wing body 100 is held by the frame body 200 by inserting the wing body 100 into the frame body 200 from the front end side. It is supported from above and below by the frame body 200. The wing body 100 is supported up and down by the frame body 200, whereby the vertical displacement of the wing body 100 with respect to the frame body 200 can be sufficiently suppressed, and an assembly-type fastener slider with sufficient strength can be realized. In this example, the wing body 100 is divided into an upper wing plate 110 and a lower wing plate 120, and the attachment to the frame body 200 is performed separately for each of the upper wing plate 110 and the lower wing plate 120.

  Even when the upper wing plate 110 is displaced to the lower wing plate 120 side in a state where the upper wing plate 110 and the lower wing plate 120 are attached to the frame body 200, the usage state of the fastener slider 10, that is, the fastener slider 10 is illustrated. 3, the fastener element 30 is provided between the upper wing plate 110 and the lower wing plate 120. The fastener element 30 moves toward the lower wing plate 120 side. Displacement of the upper blade 110 is prevented. The same applies to the displacement of the lower blade 120 toward the upper blade 110.

  The fastener slider 10 is, for example, one of the components of the slide fastener 90 in FIG.

The relationship between the engaging convex portion 250 and the connecting plate 235 can be similarly described. That is, the engaging convex part 250 extends in a convex shape at a position away from the left and right ends of the connecting plate 235 toward the left and right center sides, in the case of the illustration, in the left and right center.

  Since the engagement convex part 250 is accommodated in the engagement groove 160, the left-right displacement between the wing body and the frame body can be regulated in a manner that avoids the influence on the movement of the fastener element. Furthermore, the strength of the frame portion 201 is maintained or enhanced by the engagement convex portion 250. Since the engaging convex portion 250 is accommodated in the engaging groove 160, even if it is formed in a wall shape having a long front and rear length, the movement of the fastener element is not affected, and the strength is increased by the increase in the front and rear length. . The number of engagement grooves 160 and the number of engagement protrusions 250 are not necessarily limited to one, and may be two or more. A configuration in which a plurality of engaging convex portions 250 are inserted into one engaging groove 160 may be adopted.

  A partition wall 240 that extends linearly in the front-rear direction is integrally provided on the connecting plate 235 and the engaging projection 250 at the middle position between the upper plate 210 and the lower plate 220. Spaces for arranging the wing plate 110 and the lower wing plate 120 are separated from each other. The partition wall 240 is provided so as to run in parallel with the upper plate 210 and the lower plate 220, but the longitudinal length from the connecting plate 235 is shorter than the longitudinal length of the upper plate 210 and the lower plate 220. The partition wall 240 has a partition wall front portion 241 that gradually increases in the lateral width from the front to the rear, and a lateral width that gradually decreases from the front to the rear, as in the pillar portion 130 described later. The partition part rear part 242 to reach is included. The lateral width of the partition wall 240 is maximized between the partition wall front part 241 and the partition wall rear part 242.

  The connection plate 235 has a constricted shape in which the left and right widths are wide at the upper end portion and the lower end portion, but the left and right widths are narrow at the middle portion thereof, as can be well understood from the reference of FIG. Protruding into the movement path of the fastener element is avoided or reduced in degree and does not affect the movement of the fastener element. In addition, since a certain amount of width is secured at the upper and lower ends of the connecting plate 235, the connection to the upper plate 210 and the lower plate 220 having a certain amount of right and left width is preferably ensured, and the frame body 200 has high strength. It can be secured.

  The upper plate 210 and the lower plate 220 extend backward by the same length from the connecting position of the connecting plate 235 while maintaining the same left-right width. It is desirable that the left and right widths of the upper plate 210 and the lower plate 220 are wide, so that the function as a support plate can be sufficiently ensured. It is preferable that the left and right widths of the connecting plate 235, in particular between the upper and lower sides, are narrow. It is preferable that the front opening of the fastener slider 10 which is the entrance / exit of the fastener element 30 is arranged on the left and right sides of the connecting plate 235 so as to eliminate the influence on the movement of the fastener element as much as possible. From this point of view, it is desirable that the connecting plate 235 be wide at the upper and lower ends and narrow at the upper and lower intermediate portions.

  It is desirable to provide first engagement protrusions (protrusions) 211 and 221 for engaging the wing body 100 at the rear end portions of the upper plate 210 and the lower plate 220. For convenience, the upper plate 210 side is referred to as a first upper engagement protrusion 211, and the lower plate 220 side is referred to as a first lower engagement protrusion 221. A first upper engagement protrusion 211 is provided to engage with the upper wing plate 110, and a first lower engagement protrusion 221 is provided to engage with the lower wing plate 120. The first upper engagement protrusion 211 and the first lower engagement protrusion 221 each have a front vertical lock surface and a rear inclined guide surface. With this configuration, the first cover on the wing body 100 side as described later is provided. Smooth engagement with the engaging portion 114 and sufficient locking after the engagement can be ensured.

  In this embodiment in which the wing body 100 is provided not by integrating the upper wing plate 110 and the lower wing plate 120 but by dividing them, it is desirable to provide a partition wall 240 at an intermediate position between the upper plate 210 and the lower plate 220. Furthermore, the partition wall 240 is preferably smaller in size than the upper plate 210 and the lower plate 220. The partition wall portion 240 is configured such that the outer peripheral portion thereof can be inserted into the groove in the head portion of the fastener element 30, thereby facilitating stabilization of movement of the fastener element 30. Further, in this case, a relatively large plane size of the partition wall 240 can be secured, the stability of inserting the upper blade 110 between the upper plate 210 and the partition 240 is improved, and the lower plate 220 and the partition wall The stability of inserting the lower blade 120 between 240 can be improved.

  The pull handle attaching column 202 is an optional cantilever portion extending in an arc from the base end connected to the upper surface of the upper plate 210. The base end is connected to the upper plate 210 and the free end is the upper plate 210. It is arranged further rearward. The proximal end of the pull handle mounting column 202 may be called the front end, and the free end thereof may be called the rear end. In this embodiment, the handle attachment column 202 extends further to the rear than the rear ends of the upper plate 210 and the lower plate 220, thereby ensuring engagement between the handle attachment column 202 and the upper blade plate 110. Become. A holding space 205 for receiving and holding the bar portion 320 of the handle 300 is defined between the handle attachment column 202 and the upper plate 210.

  A second engaging protrusion (protrusion) 261 for engaging with the upper blade 110 is provided on the flat surface 253 facing the lower side at the free end of the pull handle mounting column 202. The second engagement protrusion 261 has a substantially L-shaped bent shape with the tip thereof facing backward, and is provided with a lock surface 2612 facing the flat surface 253 on which the second engagement protrusion 261 is provided. Further, the second engaging projection 261 is provided with a rear reinforcing portion 2613 that connects the flat surface 253 and the lock surface 2612 at the center of the left and right sides, and further, a front reinforcing portion 2614 is provided on the opposite side. Thus, by providing at least one reinforcement part in the 2nd engagement protrusion 261, the mechanical strength of the 2nd engagement protrusion 261 is suitably ensured. Note that the flat surface 253 may be referred to as a second engagement protrusion arrangement surface.

  Although not necessarily limited to this mode, the illustrated engagement convex portion 250 is a wall portion that is narrow in the left-right direction and extends in the front-rear direction, and connects the upper plate 210 and the lower plate 220 up and down in the center in the left-right direction. Moreover, it connects with the connection board 235 in the center of right and left. Due to the configuration of the engagement convex portion 250, the displacement of the lower plate 220 with respect to the upper plate 210 and / or the opposite displacement is less likely to occur, and the mechanical strength of the frame body 200 is suitably ensured. The engagement convex portion 250 may be divided into a plurality of front and rear portions, and a gap may be provided between each divided portion. You may provide many holes which penetrate the engaging convex part 250. FIG.

  The engagement convex portion 250 is desirably narrow in the left and right directions, and is sufficiently narrower than the left and right widths of the upper plate 210, the lower plate 220, and the connecting plate 235. In a certain form, the maximum left-right width of the engaging convex portion 250 is smaller than the minimum left-right width of the connecting plate 235. For example, the maximum left / right width of the engaging convex portion 250 is 1/2 or less, more preferably 1/3 or less, and even more preferably 1 or less of the maximum left / right width of the upper plate 210 or the lower plate 220 or the connecting plate 235. / 4 or less, and in some cases, 1/5 or less. The left and right widths of the engaging projections 250 are set so as to have a certain width from the viewpoint of securing mechanical strength. For example, the minimum left-right width of the engaging convex portion 250 is 1/10 or more of the minimum left-right width of the upper plate 210, the lower plate 220, or the connecting plate 235, sometimes 1/9 or more, and sometimes 1 / 8 or more.

  The engaging convex portion 250 is apparently divided into upper and lower portions by the partition wall portion 240. In other words, the engagement protrusion 250 includes an upper engagement protrusion 251 above the partition wall 240 and a lower engagement protrusion 252 below the partition wall 240. The upper engaging convex portion 251 gradually decreases in the lateral width as it goes upward from the upper and lower intermediate positions of the upper plate 210 and the lower plate 220, in this example, from the position of the partition wall 240. The left and right widths of the lower engaging convex portion 252 gradually decrease as it goes downward from the position of the partition wall portion 240. The configurations of the upper engaging convex portion 251 and the lower engaging convex portion 252 do not need to be the same, and may be appropriately different.

  On the lower surface of the upper plate 210 and the upper surface of the lower plate 220, auxiliary engaging convex portions 263 that are connected to the engaging convex portions 250 and extend further rearward are provided. The auxiliary engaging convex portion 263 is provided at the left and right intermediate portion between the left and right ends of the upper plate 210 and the lower plate 220, in this example, the left and right center, and extends rearward from the engaging convex portion 250 at a constant height. The height of the auxiliary engagement convex portion 263 is, for example, not more than the thickness of the upper plate 210 and the lower plate 220 and not more than the thickness of the flat plate portions of the upper blade plate 110 and the lower blade plate 120. The surface facing the rear of the auxiliary engagement convex portion 263 is an inclined surface, but this is not necessarily the case.

  7 to 9 show the upper wing plate 110 constituting the wing body 100. Note that the lower wing plate 120 has the same configuration as the upper wing plate 110, and therefore redundant illustration is omitted. By configuring the upper wing plate 110 and the lower wing plate 120 to have the same configuration, it is possible to prevent a mistake of upside down in the assembly process.

  The upper wing plate 110 is a substantially flat plate-like member having a lower surface facing the lower wing plate 120 and an upper surface on the opposite side of the lower wing plate 120, and a front portion having a constant width and a front portion that is wide from the rear to the left and right. including. A flange portion 140 is provided on the left and right sides of the upper wing plate 110, and a column portion 130 constituting an upper portion of the guide column of the fastener slider 10 is provided on the front end thereof. The lower wing plate 120 has the same configuration as the upper wing plate 110. The lower wing plate 120 is a flat plate member having an upper surface facing the upper wing plate 110 and a lower surface opposite to the upper surface, and a column portion 130 constituting a lower portion of the guide column of the fastener slider 10 at the front end thereof. Is provided. In this embodiment, the pillar portion 130 is provided separately, but may be non-divided as described in the fourth embodiment. Since the lower surface of the upper wing plate 110 faces the upper surface of the lower wing plate 120, these may be referred to as opposed inner surfaces.

  The upper wing plate 110 has an engagement groove 160, an auxiliary engagement groove 112, a stop portion 113, a first engaged portion 114, and a second engaged portion 115 arranged linearly from the front end to the rear end side. It has the structure made. The same applies to the lower wing plate 120, and the description regarding the lower wing plate 120 will be omitted in the following description.

  The engagement groove 160 extends linearly from the front end to the rear end side of the upper wing plate 110 at the left and right center of the upper wing plate 110. In this embodiment, since the column part 130 is provided in the left and right center of the front end of the upper blade 110, the engagement groove 160 penetrates the column part 130 up and down. The engaging protrusion 250 of the connecting portion 230 of the frame body 200 can be inserted into the engaging groove 160. The engagement of the engagement protrusion 250 and the engagement groove 160 favorably guides the insertion of the upper wing plate 110 into the frame body 200 or the frame 200 into the upper wing plate 110, and the frame 200 and the upper wing. The left-right displacement of the upper blade plate 110 with respect to the frame body 200 after the plate 110 is assembled is sufficiently restricted. The engagement groove 160 is a bottomless groove provided in such a manner as to penetrate the column part 130 from the upper surface of the upper blade 110.

  4 and 8 will be described in comparison. The front / rear length L2 of the engagement groove 160 is preferably the same as or longer than the front / rear length L1 of the engagement protrusion 250. In short, L1 ≦ L2 is satisfied. By satisfying this condition, the engaging convex portion 250 is completely accommodated in the engaging groove 160, the engaging convex portion 250 is included in the column portion 130, and the fastener element is mainly based on the design of the column portion 130. Can be defined. In other words, the engagement convex portion 250 does not affect the movement of the fastener element.

  As shown in FIG. 8, the column part 130 has a column front part 131 in which the left and right widths gradually increase from the front to the rear, and the column rear part that gradually decreases in the left and right widths from the front to the rear and reaches the rearmost end. 132. The horizontal width of the column part 130 is maximized between the column front part 131 and the column rear part 132. The engaging groove 160 extends from the front to the rear in the left and right center of the column front portion 131, and extends from the front to the rear in the left and right center of the column rear portion 132 toward the rearmost end 133 of the column rear portion 132 and before reaching it. Terminate with According to such a configuration, a sufficient longitudinal length of the engagement groove 160 can be ensured, and sufficient engagement between the engagement groove 160 and the engagement convex portion 250 can be ensured.

  The ratio of the front / rear length L2 of the engagement groove 160 to the front / rear length L3 of the column part 130 is preferably L2> L3 / 2, and more preferably L2> L3 × 3/4.

  An auxiliary engagement groove 112 is provided further rearward of the engagement groove 160. The auxiliary engagement groove 112 is a shallow concave portion with a bottom that does not penetrate the upper blade 110, unlike the engagement groove 160, although extending in the front-rear direction with the same lateral width as the engagement groove 160. The above-described auxiliary engagement convex portion 263 can be inserted into the auxiliary engagement groove 112, whereby the auxiliary engagement convex portion 263 and the auxiliary engagement groove 112 are engaged, and the upper blade plate with respect to the frame body 200 is engaged. 110 displacement, in particular, left-right displacement is restricted.

  On the upper surface of the upper wing plate 110, there is further provided a concave stop portion 113 communicating with the auxiliary engagement groove 112 and having the same depth as the auxiliary engagement groove 112. The left-right width of the stop portion 113 is wider than the left-right width of the auxiliary engagement groove 112, and the left-right width is set slightly wider than the left-right width of the first engagement protrusion 211 provided on the frame body 200. . The stop portion 113 is provided to temporarily stop the first engagement protrusion 211 before the first engagement protrusion 211 of the frame body 200 is engaged with the first engaged portion 114, and thereby, as described later. Assembly can be realized.

  The first engaged portion 114 further rearward than the stop portion 113 is a recess in which the upper surface of the upper blade 110 is recessed. When the first engagement protrusion 211 of the frame body 200 is engaged with the first engaged portion 114, the removal of the upper blade plate 110 from the frame body 200 is suitably restricted. In addition, the 1st to-be-engaged part 114 may be a through-hole which penetrates the upper wing board 110 instead of a recessed part.

  The second engaged portion 115 further rearward than the first engaged portion 114 is provided in the form of a through hole that penetrates the upper blade plate 110. The second engaged portion 115, which is a through hole, is provided with a protrusion 1155 that protrudes from the wall surface inward in the radial direction of the through hole. The lock surface 2612 of the second engagement protrusion 261 described above is engaged with the protrusion 1155, and the engagement between the second engagement protrusion 261 and the second engaged portion 115, that is, the pulling attachment column 202 and the upper wing plate 110. Engagement is ensured.

  When the second engagement protrusion 261 of the handle attachment column 202 of the frame body 200 is engaged with the second engaged portion 115, the removal of the upper blade plate 110 from the frame body 200 is sufficiently restricted. By engaging the second engagement protrusion 261 and the second engaged portion 115 while bending the pull attachment column 202 downward, after the engagement, the pull attachment plate 202 and the upper wing plate 110 are attracted to each other. It is possible to secure sufficient solidity between the upper blade 110 and the frame body 200. The opening shape of the second engaged portion 115 that opens in the upper blade 110 extends back and forth so as to allow the insertion of the rear reinforcing portion 2613 and the front reinforcing portion 2614 of the second engaging protrusion 261 described above. ing.

  A manufacturing method of the assembly-type fastener slider 10, that is, a process of attaching the wing body 100, here, the upper wing plate 110, to the frame body 200 will be described with reference to FIG. Each component is manufactured in advance by molding a resin material.

  First, the pull handle 300 which is an optional component is engaged with the pull attachment column 202 of the frame body 200. The gap between the puller mounting column 202 and the upper plate 210 is widened by elastic deformation of the puller mounting column 202, and the bar portion 320 of the puller 300 is inserted between them, thereby holding between the puller mounting column 202 and the upper plate 210. The bar portion 320 of the handle 300 is received and held in the space 205. In addition, when omitting the pull handle 300, the assembly process of the pull handle 300 to the frame body 200 is naturally unnecessary.

  Next, as shown in FIG. 10A, the upper wing plate 110 is inserted between the upper plate 210 and the partition wall 240 of the frame body 200, and at the same time, the upper wing plate 110 is inserted into the engagement groove 160 of the upper wing plate 110. The upper engaging convex portion 251 of the frame body 200 is inserted. The engagement groove 160 is long in the front-rear direction, and similarly the upper engagement convex portion 251 is long in the front-rear direction. Therefore, the upper wing plate 110 is preferably inserted into the frame body 200 in the front-rear direction by these engagements. Guided. As shown in FIG. 10A, both the first engagement protrusion 211 and the second engagement protrusion 261 of the frame body 200 correspond to the corresponding first engaged portion 114 and second engaged portion 115, respectively. Not engaged.

  When the upper blade plate 110 is further inserted into the connecting plate 235 side which is the back side of the frame portion 201, the state shown in FIG. 10B, the second engagement protrusion 261 is disposed in the hole of the second engaged portion 115, but the lock surface 2612 of the second engagement protrusion 261 is not in the second engaged portion 115. The protrusion 1155 is not locked. Further, the first engagement protrusion 211 is temporarily stopped at the stop portion 113, and the first engagement protrusion 211 is not engaged with the first engaged portion 114. That is, the state of FIG. 10B is an intermediate transition state that has not reached the final engaged state.

  Next, when the upper wing plate 110 is further moved to the connecting plate 235 side, which is the inner side of the frame portion 201, while the puller attachment column 202 is pushed down to the upper wing plate 110 side to bend the puller attachment column 202, FIG. The assembly can be completed as shown in FIG. 10C, the upper wing plate 110 is pulled upward by the second engagement protrusion 261 of the pull handle attachment column 202, while the second engagement protrusion 261 of the pull handle attachment column 202 is pulled by the upper wing plate 110. It will be in the state pulled down, and a stronger solidarity of upper wing board 110 and frame 200 can be secured.

  In FIG. 10C, the lower wing plate 120 assembled to the frame body 200 is also shown for reference. When the assembly of the wing body 100 with respect to the frame body 200 is completed as shown in FIG. 10C, the wing body 100 cannot be extracted from the frame body 200 substantially. This is because the wing body 100 and the frame body 200 are engaged with each other at a plurality of engagement positions and the extraction is restricted, and the upper wing plate 110 is applied with an attractive force between the wing body 100 and the frame body 200 as described above. It is because it has been. By making disassembly of the assembled fastener slider 10 substantially impossible, when the fastener slider 10 is incorporated in the slide fastener 90 and used, the slide fastener 90 cannot be used due to disassembly. It can be avoided.

  Ensuring the intermediate transition state shown in FIG. 10 (b) is not limited to the upper plate 210 and the upper wing plate 110, but is particularly advantageous in connecting the pull attachment bracket 202 and the upper wing plate 110, As described with reference to FIG. 10 (c), the second engagement protrusion 261 of the pull handle mounting column 202 is formed on the second engaged portion 115 of the upper blade plate 110 while bending the pull handle mounting column 202 toward the upper blade plate 110. By engaging, the pulling attachment column 202 and the upper wing plate 110 are brought into a state of being attracted after assembly, and a better connection between the frame body 200 and the upper wing plate 110 can be secured. In the form where the lower wing plate 120 does not engage with the pulling attachment column 202, the second engaged portion 115 of the lower wing plate 120 is unnecessary, but the same configuration as the upper wing plate 110 is used as described above. As a result, assembly errors of the fastener slider 10 can be prevented.

  Furthermore, in the present embodiment, as described at the beginning, a structure that cannot be realized by a mold apparatus for a non-assembly type resin fastener slider, the end of the left and right flange portions 140 as shown in FIG. A claw portion 145 provided to protrude toward the column portion 130 at the front end is provided on the upper wing plate 110 and the lower wing plate 120. As shown in FIG. 11, when an external force F such as lateral pulling is applied to the fastener tape 20, the claw portion 145 is configured to enter between adjacent fastener elements 30, thereby sliding on the fastener element row. The position of the moving fastener slider 10 can be temporarily locked. As is apparent from FIG. 11, the cross-sectional shape of the connecting portion 230 is T-shaped in an arbitrary plane perpendicularly intersecting the vertical direction, and the engagement convexity is based on the left and right center of the connecting plate 235 extending left and right. The portion 250 extends rearward longer than the left and right width of the connecting plate 235.

Second Embodiment
The second embodiment will be described with reference to FIGS. 12 and 13. FIG. 12 is an exploded perspective view of the wing body of the fastener slider. FIG. 13 is a front view of the upper wing plate of the fastener slider.

  In the present embodiment, unlike the first embodiment, an opening pattern in which a plurality of openings 190 are arranged is provided on the upper and lower surfaces of the wing body 100. By providing the opening pattern, raw materials such as resin used for the wing body can be reduced, the weight thereof can be reduced, and the fastener slider can be easily slid around. In consideration of design, it is desirable to arrange the openings 190 regularly, for example, in a lattice pattern.

  In the present embodiment, a plurality of reinforcing ribs 195 are provided on the opposing inner surface of the wing body 100 in place of or in addition to the description in the previous paragraph. Reinforcing ribs 195 are provided on the inner surfaces of the upper wing plate 110 and the lower wing plate 120 of the wing body 100, and the area where the fastener element 30 contacts the inner surfaces of the upper wing plate 110 and the lower wing plate 120 is reduced. The sliding resistance of the fastener slider 10 is reduced. Furthermore, a recess or a through hole is formed in accordance with the reinforcing rib 195, so that raw materials such as resin used for the wing body 100 can be reduced, and the weight can be reduced. Note that when the openings are formed between the reinforcing ribs 195, design characteristics can be added to the wing body 100 by the arrangement of the reinforcing ribs 195.

  In the present embodiment, in place of or in addition to the matters described in the previous paragraph, the first engagement toward the second engaged portion 115 between the first engaged portion 114 and the second engaged portion 115 is performed. A restriction structure 116 that restricts the movement of the engagement protrusion 211 is provided. Accordingly, the first engagement protrusion 211 is prevented from moving over the first engaged portion 114 to the second engaged portion 115 side, and assembly failure of the fastener slider 10 can be prevented.

  As can be seen from FIG. 12, the reinforcing rib 195 includes a first reinforcing rib that extends diagonally from the lower left to the upper right and a second reinforcing rib that extends from the lower right to the upper left. The main plate portion of the upper wing plate 110 is constructed by integrating the first reinforcing rib and the second reinforcing rib. An opening 190 is opened between the adjacent first reinforcing ribs, and an opening 190 is opened between the adjacent second reinforcing portions.

  As shown in FIG. 12, the restricting structure 116 is desirably provided in a U shape so as to surround the first engaged portion 114. In more detail, when the wing body 100 is assembled to the frame body 200, it is desirable that the regulation structure 116 is protruded in a manner surrounding the upper plate 210 of the frame body 200. Thereby, the movement of the 1st engagement protrusion 211 from the 1st to-be-engaged part 114 to the 2nd to-be-engaged part 115 can be controlled suitably.

  The opening pattern and the rib pattern shown in FIG. 12 are examples, and each pattern may be configured as shown in FIG. That is, the opening shape of the opening 190 is arbitrary, and is not limited to a rhombus, but may be an opening shape such as a square, a rectangle, a circle such as a perfect circle and an ellipse, a star shape, a crescent shape, or any degree of deformation thereof. I do not care. The number of openings may be two or more, and an arrangement of two openings can be understood as an opening pattern. The number of reinforcing ribs is also arbitrary, and an arrangement of two or more reinforcing ribs can be understood as a rib pattern.

<Third Embodiment>
A third embodiment will be described with reference to FIGS. 14 to 16. FIG. 14 is an assembly process diagram of the fastener slider. FIG. 15 is a front view of the upper wing plate of the fastener slider. 16 is a cross-sectional view of the upper wing plate of the fastener slider, and shows a cross section taken along the two-dot broken line XVI-XVI in FIG.

  In this embodiment, the 1st to-be-engaged part 114 which the 1st engagement protrusion 211 engages is provided as the pivot piece 117 which can be pivoted up and down instead of a hole. Even in such a case, the same effects as those in the above-described embodiment or any combination thereof can be obtained.

  In the present embodiment, in addition to or in place of the description in the above paragraph, the handle attachment column 202 does not engage with the upper blade 110 at the rear end, that is, the second engagement protrusion is omitted. The upper wing plate 110 is provided with a retaining piece 118 that can pivot vertically on the rear end side of the first engaged portion 114.
