The vertical length of the fourth leg 40 is equal to the vertical length of the third leg 38. In the present embodiment, the vertical lengths of the third leg portion 38 and the fourth leg portion 40 of the lower member 22 are the same as the first leg portion 28 of the upper member 21 and the length of the second head portion 36. It is shorter than the vertical length of the second leg portion 31. In other words, in a state where the bolt 23 is inserted into the insertion hole 27 and screwed into the female screw hole 37, the first to fourth engagements from the contact point between the lower surface of the first head 26 and the upper surface of the second head 36. The vertical distances to the engaging points of the pawls 29, 32, 39, 41 and the lip portion 13 are equal to each other.

  The bolt 23 includes a prismatic head portion 46 and a shaft portion 47 protruding from the head portion 46 and engraved with a screw thread. The outer diameter of the head 46 is larger than the inner diameter of the insertion hole 27, and the outer diameter of the shaft portion 47 is smaller than the inner diameter of the insertion hole 27. The shaft 47 is screwed into the female screw hole 37. It is preferable that the tip of the shaft portion 47 is flat.

  With the first head 26 overlaid on the second head 36, the bolt 23 is inserted from its tip so as to pass through the insertion hole 27 and the female screw hole 37 in order from the upper side. The head portion 46 is formed in a size that cannot pass through the insertion hole 27, and the shaft portion 47 passes through the insertion hole 27 and is screwed into the female screw hole 37, whereby the upper member 21, the lower member 22, and The bolt 23 constitutes the clip 1 which is one assembly.

  Since the inner diameter of the insertion hole 27 of the upper member 21 is larger than the outer diameter of the shaft portion 47, the upper member 21 and the combined body of the lower member 22 and the bolt 23 can be relatively rotated about the shaft portion 47. It has become. When the first leg portion 28 and the third leg portion 38 are rotated closest to each other and the second leg portion 31 and the fourth leg portion 40 are closest to each other, that is, first to fourth. When the leg portions 28, 31, 38, 40 and the first to fourth locking claws 29, 32, 39, 41 are arranged substantially linearly in plan view, the first locking claw 29 and the third locking claw 39 The distance in the left-right direction between the protruding ends and the distance in the left-right direction between the protruding ends of the second locking claw 32 and the fourth locking claw 41 are equal to each other and become L1 (see FIG. 4) (close state). At this time, the second head 36 has a shape with the front left and rear right corners cut off in a plan view, so that the second head 36 does not become an obstacle to the rotation. The first leg portion 28 and the third leg portion 38 are rotated so that they are closest to each other, and the second leg portion 31 and the fourth leg portion 40 are closest to each other, or the same direction from this state. When the second head portion 36 is rotated, the notched corner portion of the second head portion 36 can abut one or both of the first protrusion portion 30 and the second protrusion portion 33.

  Further, the upper member 21 and the lower member 22 are such that the longitudinal direction of the first head portion 26 and the second head portion 36 is along the front-rear direction, and each of the first to fourth leg portions 28, 31, 38, 40 is The main surfaces are parallel to each other and face in the left-right direction so that the first to fourth locking claws 29, 32, 39, 41 constitute the apex of the parallelogram in plan view. When the upper member 21 and the lower member 22 are relatively rotated, the left-right direction distance between the protruding ends of the first locking claw 29 and the third locking claw 39, the second locking claw 32 and the second locking claw The distance in the left-right direction between the projecting ends of the four locking claws 41 is equal to each other and becomes L2 (see FIG. 5) (expanded state). L1 is smaller than the distance L3 (see FIGS. 4 and 5) between the lip portions 13, and L2 is set larger than L3.

  Next, with reference to FIGS. 4-6, the coupling | bonding procedure of the field receiver 3 and the field edge 4 by the clip 1 is demonstrated. 4 to 6, (a) is a rear view, and (b) is a bottom view in which the field edge receiver 3 and the field edge 4 are omitted. First, as shown in FIG. 4, the field edge 4 is arranged below the field edge receiver 3 in a direction perpendicular to the field edge receiver 3 in a plan view, and the field edge is formed by holding means (not shown) such as a wire or handheld. 4 is temporarily fixed. Next, above the portion where the field edge receiver 3 and the field edge 4 intersect in plan view, below the first head 26 and the second head 36, the first to fourth legs 28, 31, 38, The clip 1 is arranged so that 40 is located. Next, the first leg part 28 and the third leg part 38 are arranged on the front side in the width direction of the field edge receiver 3, and the second leg part 31 and the fourth leg part 40 are on the rear side in the width direction of the field edge receiver 3. The clip 1 is moved downward so that the clip 1 receives the field edge receiver 3. Thereby, each of the 1st head 26 and the 2nd head 36 is arrange | positioned so that the upper part of the field receiver 3 may be straddled. At this time, the upper member 21 and the lower member 22 are relatively rotated so that the first leg portion 28 and the third leg portion 38 are closest to each other, and the second leg portion 31 and the fourth leg portion 40 are Are in close proximity to each other. By setting the proximity state, the distance between the protruding ends of the first locking claw 29 and the third locking claw 39 and the distance between the protruding ends of the second locking claw 32 and the fourth locking claw 41 are L1. Becomes smaller than the distance L3 between the lip portions 13. In this state, the first to fourth locking claws 29, 32, 39, 41 are inserted between the lip portions 13, and the lower ends of the first to fourth leg portions 28, 31, 38, 40 are Place inward. When the lower surface of the second head 36 is in contact with the upper surface of the upper wall portion 7 of the field edge receiver 3, the lower ends of the first to fourth leg portions 28, 31, 38, and 40 are lip in the field edge 4. It is arranged at a predetermined depth below the portion 13.

  Next, as shown in FIG. 5, the upper member 21 is arranged such that the first leg portion 28 and the third leg portion 38 are separated from each other, and the second leg portion 31 and the fourth leg portion 40 are separated from each other. And the lower member 22 are relatively rotated, and the longitudinal directions of the first head portion 26 and the second head portion 36 are along the front-rear direction, and the first to fourth leg portions 28, 31, 38, 40 The surfaces are parallel to each other and set in an expanded state facing the left and right direction. By making it into an expanded state, the left-right direction distance between the protruding ends of the first locking claw 29 and the third locking claw 39 and the left and right distance between the protruding ends of the second locking claw 32 and the fourth locking claw 41 are set. The directional distance becomes L2 and is larger than the distance L3 between the lip portions 13, and the first locking claw 29 and the fourth locking claw 41 can be hooked on the left lip portion 13, respectively. Each of the second locking claw 32 and the third locking claw 39 can be hooked to the right lip portion 13.

  Next, the amount of protrusion of the bolt 23 from the lower surface of the second head 36 is increased by screwing the bolt 23 into the female screw hole 37. Since the front end portion of the bolt 23 abuts against the upper surface of the upper wall portion 7 of the field receiver 3, the protruding amount of the bolt 23 increases, so that the upper member 21 placed on the lower member 22 and the lower member 22. Is displaced upward with respect to the field edge receiver 3 and the field edge 4. As a result, as shown in FIG. 6, each of the first locking claw 29 and the fourth locking claw 41 moves into the lip groove 14 on the left side and gets caught, and the second locking claw 32 and the third locking claw 32 are engaged. Each of the pawls 39 moves into the right lip groove 14 and is caught. As described above, the clip 1 joins the field edge 4 to the field edge receiver 3.

  At this time, the first locking claw 29 and the fourth locking claw 41 are locked in the left lip groove 14, and the second locking claw 32 and the third locking claw 39 are locked in the right lip groove 14. Since the first to fourth locking claws 29, 32, 39, 41 and the lip groove 14 cooperate with each other, the clip 1 and the field edge 4 with respect to the vertical direction are relative to each other. Prevent rotation. Further, the first projecting portion 30 and the third leg portion 38 are in contact with or close to the vertical wall portion 6 of the field edge receiver 3, and the second projecting portion 33 and the fourth leg portion 40 are disposed behind the upper wall portion 7. Since the fourth leg 40 is in contact with or close to the side edge, and the fourth wall 40 is further in contact with or close to the rear side edge of the lower wall part 8, the first protrusion 30, the second protrusion 33, the third leg 38 and The fourth leg 40 cooperates to prevent relative rotation between the clip 1 and the field edge receiver 3 about the vertical direction. Therefore, the relative rotation of the field edge receiver 3 and the field edge 4 about the vertical direction is prevented via the clip 1.

  In the clip 1 of the present embodiment, the upper member 21 is sandwiched between the insertion member 27 and the shaft member 47 of the bolt 23 through the insertion hole 27 and the lower member 22 screwed with the head of the bolt 23. Is in a state. Therefore, the upper member 21 and the assembly of the lower member 22 and the bolt 23 are assembled so as to be able to relatively rotate about the shaft portion 47. By rotating, the lateral distance between the lower ends of the first leg portion 28 and the third leg portion 38 and the lateral distance between the lower ends of the second leg portion 31 and the fourth leg portion 40 can be changed. The left-right distance between the protruding ends of the first locking claw 29 and the third locking claw 39 and the left-right distance between the protruding ends of the second locking claw 32 and the fourth locking claw 41 can be changed. . For this reason, in order to pass the 1st-4th latching claw 29,32,39,41 between the lip | rip parts 13, the upper side member 21 and the lower side member 22 (especially 1st-4th leg part 28,31, 38, 40) need not be flexible. Therefore, it is possible to increase the rigidity of the upper member 21 and the lower member 22 and to increase the load resistance (strength) and earthquake resistance of the clip 1.

  Further, the clip 1 can be easily inserted into the field edge 4. When inserting the clip 1 into the field edge 4, the first leg portion 28 and the third leg portion 38 are close to each other, and the second leg portion 31 and the fourth leg portion 40 are close to each other. The upper member 21 and the lower member 22 are rotated relative to each other with the shaft portion 47 as the axis, and the distance between the projecting ends of the first to fourth locking claws 29, 32, 39, 41 in the left-right direction is reduced. Therefore, the first to fourth locking claws 29, 32, 39, 41 can be inserted between the lip portions 13. Further, after the insertion, by rotating the upper member 21 and the lower member 22 in the opposite directions, the distance between the projecting ends of the first to fourth locking claws 29, 32, 39, 41 in the left-right direction is increased. Each of the first to fourth locking claws 29, 32, 39, 41 is arranged below the lip portion 13 (lip groove 14). Thereafter, when the bolt 23 is screwed into the female screw hole 37, each of the first to fourth locking claws 29, 32, 39, 41 is pulled upward and hooked on the lip portion 13 (lip groove 14). As described above, when the clip 1 is used, at the work site, from the state where the upper member 21, the lower member 22 and the bolt 23 are in one assembly, the connection work between the field edge 4 and the field edge receiver 3 is performed. You can start. Therefore, the clip 1 can be mounted easily and quickly as compared with a type in which the locking claw is inserted inward of the field edge 4 for each member and then the members are combined.

  Since each of the upper member 21 and the lower member 22 is arranged so as to straddle the upper portion of the field edge receiver 3 and is coupled to the field edge 4 at both ends thereof, the upper member 21 and the lower member 22 are temporarily coupled by the bolts 23. Even if the upper member 21 and the lower member 22 are separated, the upper member 21 and the lower member 22 can each independently maintain the support of the field edge 4 with respect to the field edge receiver 3.

  Although the description of the specific embodiment is finished as described above, the present invention is not limited to the above embodiment and can be widely modified. For example, the first protrusion 30 and the second protrusion 33 may be omitted. Further, the mounting angle between the field edge 3 and the field edge receiver 4 can be changed by shifting the positions of the first protrusion 30 and the second protrusion 33 by the same distance in opposite directions in the front-rear direction. . Further, the material of the upper member 21, the lower member 22, and the bolt 23 is not limited to metal, and may be resin, for example.
