  As shown in FIGS. 1 to 14, the slide fastener 400 includes a pair of left and right element rows 300, a slider 200 that moves back and forth to open and close the pair of left and right element rows 300, and a stopper 350. As the slider 200 moves forward, the pair of left and right element rows 300 is closed, and when the slider 200 moves backward, the pair of left and right element rows 300 is opened.

  In each of the left and right element rows 300, the hook elements 100 are continuously constructed via the ring body 150. The hook element 100 includes a main body 120 and a hook 110 connected to the main body 120. The main body 120 includes an engaged portion 130 with which the hook portion 110 of the hook element 100 of the mating partner is engaged. Specifically, an engaged portion 130 protruding forward is provided at the front end portion of the main body 120, and a later-described eye hole 121 through which the ring body 150 is passed is provided in the engaged portion 130. The hook element 100 is manufactured by molding a metal raw material with a mold, for example, die casting. The ring body 150 is originally a metal wire, and is processed into a ring shape so as to connect the hook elements 100 to each other by machine or manual work. The ring body 150 may not be a closed ring body but may be a partially opened ring body.

  Engagement and disengagement between the left and right hook elements 100 through the ring body 150 is achieved by the forward and backward movement of the slider 200. Note that the left and right hook elements 100 to be engaged are not adjacent to each other right and left but are offset from each other in the front-rear direction.

  The forward movement of the slider 200 causes the hook portion 110 of the left hook element 100 to be inserted into the right wheel body 150, and the hook portion 110 of the left hook element 100 passes through the right wheel body 150 of the main body portion 120 of the right hook element 100.

Similarly, the hook part 110 of the right hook element 100 is inserted into the left ring 150 by the advancement of the slider 200, and the hook part 110 of the right hook element 100 passes through the left ring 150 and the main body of the left hook element 100. Engage with the engaged portion 130 of the portion 120. In this way, the left and right element rows 300 are closed.

  As the slider 200 moves backward, the hook portion 110 of the left hook element 100 is extracted from the right wheel body 150, and the hook portion 110 of the left hook element 100 and the engaged portion 130 of the main body portion 120 of the right hook element 100 are extracted. Is disengaged. As the slider 200 moves backward, the hook part 110 of the right hook element 100 is extracted from the left wheel body 150, and the hook part 110 of the right hook element 100 and the engaged part 130 of the main body part 120 of the left hook element 100 are extracted. Is disengaged. In this way, the left and right element rows 300 are opened. As can be understood from the following description, the orientation of the left and right hook elements 100 and the respective ring bodies 150 is accurately controlled by the slider 200 when the slider 200 moves forward and backward.

  A pair of front and rear eye holes 121 through which a ring is passed is provided at the front and rear end portions of the main body 120 of the hook element 100, and a pair of upper and lower projections 122 extending in the front-rear direction are provided on the upper and lower surfaces of the main body 120. . The pair of upper and lower protrusions 122 are provided symmetrically. The main body 120 is provided with an attachment hole 123 on the opposite side of the hook part 110, and the convex part 122 is sandwiched between the hook part 110 and the attachment hole 123.

  With respect to the left hook element 100, the hook 110 is connected to the right edge of the main body 120, extends to the right, and then bends backward. Regarding the right hook element 100, the hook portion 110 is connected to the left edge of the main body portion 120, extends to the left side, and then bends backward. The hook part 110 has a wide base part connected to the main body part 120 and extends in a tapered or arcuate manner from the base part toward the tip, thereby ensuring sufficient engagement with the corresponding ring body 150. The

  As can be seen from FIG. 3, when the left and right element rows 300 are closed, the hook portion 110 of the left and right hook elements 100 is located at the front end where the eye holes 121 a of the right and left other hook elements 100 are present.

This promotes the connection or unity between the left and right hook elements 100.

  With respect to the hook elements 100 adjacent to the front and rear, a metal wire is passed through the eye hole 121a at the front end of the rear hook element 100 and the eye hole 121b at the rear end of the front hook element 100, and this metal wire is processed into an annular shape. Thus, the front and rear hook elements 100 are connected via the ring body 150. With respect to the same hook element 100, the left and right opening width of the eye hole 121b on the rear end side is wider than the left and right opening width of the eye hole 121a on the front end side. Further, the eye hole 121b on the rear end side is provided in an arc shape so as to surround the convex portion 122 in a short range. With this configuration, the orientation correction of the hook element 100 when the slider 200 moves forward is promoted.

  An acute angle formed by an axis L10 connecting the center of the mounting hole 123 and the tip of the hook portion 110 with respect to the axis L20 extending in the front-rear direction coincident with the extending direction of the convex portion 122 is defined as θ °. In this case, the acute angle θ ° is 50 ° or more, 90 ° or less, and more preferably 66 ° to 66.5 °. Thereby, the suitable insertion of the hook part 110 with respect to the corresponding ring body 150 is ensured.

  Note that the hook element 100 is vertically symmetric and left-right asymmetric, and the same hook element 100 can be used in the left element row 300 and the right element row 300. The ring body 150 is originally a metal wire, and has the same configuration with respect to the left and right element rows 300. Of course, the configuration of the ring body 150 in the left and right element rows 300 may be different.

As can be understood from FIG. 1, the main body 120 of the hook element 100 is supported by the support plate 245, and the hook portion 110 of the hook element 100 is supported by the lower guide plate 240. When the support plate 245 is not provided, there is a concern that the hook portion 110 of the left hook element 100 may be caught by the front end of the lower guide plate 240 when the slider 200 is advanced to close the left and right element rows 300. In this case, it becomes necessary to manually release the state in which the hook portion 110 is hooked on the front end of the lower guide plate 240. The shape of the hook part 110 itself is not so flexible from the viewpoint of ensuring sufficient engagement between the passage of the corresponding ring body 150 and the hook element 100 of the mating counterpart. In the present embodiment, based on these points, the support plate 245 is connected to the lower guide plate 240 to ensure a smoother movement of the slider 200 and to open and close the left and right element rows 300 more smoothly. To do.

  The upper surface of the support plate 245 is stepped down from the upper surface of the lower guide plate 240, and collision with the convex portion 122 on the lower surface of the hook element 100 is avoided. A step portion 244 is provided between the support plate 245 and the lower guide plate 240. The stepped portion 244 is provided with a stepped surface that connects the upper surface of the lower guide plate 240 and the upper surface of the support plate 245, and this stepped surface is a downward slope that slowly falls from the upper surface of the lower guide plate 240 to the upper surface of the support plate 245. Surface. A guide protrusion 246 extending in the front-rear direction is provided on the left edge of the support plate 245. The guide protrusion 246 corrects the posture of the ring body 150 and the hook element 100 before entering the slider 200, and makes it easy to enter the slider 200 smoothly. When the slider 200 moves forward and backward, the position of the ring body 150 and the convex portion 122 of the hook element 100 is restricted between the step portion 244 and the guide protrusion 246.

  The guide protrusion 246 does not extend across the entire length of the support plate 245. The guide protrusion 246 is not provided at the front end portion or the rear end portion of the support plate 245 but is provided at the front and rear central portions thereof, and the guide protrusion 246 functions to prevent the movement / flow of the ring body 150 and the hook element 100. Is avoided. A notch portion in which the support plate 245 is notched is provided between the guide protrusion 246 and the left lower flange portion 221. This is because the support plate 245 and the guide protrusion 246 are not necessary in this portion.

  The distance between the guide protrusion 246 and the stepped portion 244 is equal to the distance between the lower flange portion 221 and the lower partition structure 225, and is larger than the left and right width of the convex portion 122 of the hook element 100 and the left and right width of the connecting column 250. Slightly wide.

  An operation when the slider 200 is advanced to close the slide fastener 400 will be described. The slider 200 is advanced, and the left wheel 150 in front of the slider 200 is disposed on the support plate 245 and is regulated between the guide protrusion 246 and the step 244. When the slider 200 is further advanced, the hook element 100 positioned one forward of the ring body 150 is disposed on the lower guide plate 240 and the support plate 245, and the convex portion 122 on the lower surface of the hook element 100 is the guide protrusion. The position is restricted between H. 246 and the stepped portion 244. Further, the hook part 110 of the hook element 100 is disposed in a lower space between the lower guide plate 240 and the intermediate connecting part 253. When the slider 200 is further advanced, the hook portion 110 of the hook element 100 passes through the lower space described above, and ascends the third inclined surface 240m provided on the lower guide plate 240, so that the hook element 100 and the upper wing plate 210 are moved. It is introduced into the space between the lower blades 220.

  The hook portion 110 of the hook element 100 passes through the space between the upper raised portion 261 and the lower raised portion 262 and passes between the upper partition structure 215 and the lower partition structure 225. The convex part 122 on the upper surface of the main body part 120 of the hook element 100 advances in the guide groove between the upper flange part 211 and the upper partition structure 215. Similarly, the convex portion 122 on the lower surface of the main body portion 120 of the hook element 100 advances in the guide groove between the lower flange portion 221 and the lower partition structure 225. Immediately after the hook portion 110 passes through the space between the upper raised portion 261 and the lower raised portion 262, the hook portion 110 is inserted into the right-side ring body 150, and then the main body portion 120 of the mating hook element 100 is engaged. Engage with the mating portion 130.

  The guide groove between the left upper flange portion 211 and the upper partition structure 215 and the guide groove between the right upper flange portion 211 and the upper partition structure 215 are provided so as to approach slowly rearward from the front. . The guide groove between the left lower flange portion 221 and the lower partition structure 225 and the guide groove between the right lower flange portion 221 and the lower partition structure 225 are provided so as to approach slowly from the front toward the rear. . As described above, the upper wing plate 210 and the lower wing plate 220 are vertically symmetrical and are provided with four guide grooves having right and left mirror images, and the upper and lower convex portions 122 of the ring body 150 and the main body 120 of the hook element 100 are guided. .

  When the non-engaged left hook part 110 and the left ring body 150 located one rear as viewed from the right ring body 150 and the right hook element 100 come close to each other according to the guidance by the four guide grooves described above, The left hook part 110 located one forward is moved to the right and inserted into the right wheel body 150. When the slider 200 is further advanced, the hook element 100 and the ring body 150 arranged on the left and right are moved inward in the left-right direction so that the hook portion 110 is inserted deeper into the ring body 150. In this way, the hook portion 110 of the left hook element 100 passes through the right wheel body 150.
