  Since the clip of Patent Document 1 described above has a structure in which the horizontal plate portion can be easily bent in order to improve the mounting workability, the thickness of the member is thin and the strength is not excellent. Further, since the field edge is only locked from below by the locking pieces, there is room for improvement in the field edge support performance.

  On the other hand, since the joint fitting of Patent Document 2 fixes the field edge 130 and the field edge receiver 120 by tightening the bolt 103 and the nut 104, the thickness of the member can be increased and high strength can be obtained. However, since the plate material for fixing the field edge 130 and the field edge receiver 120 and the metal fitting for improving the support performance of the field edge 130 are separate members, the number of parts is large, and further, the state in which these plate material and metal hardware are held. Therefore, it is necessary to perform tightening work with the bolt 103 and the nut 104, and there is a problem that much work is required for the construction.

  From such a viewpoint, an object of the present invention is to provide a field edge fixing clip that is easy to construct and can fix a field edge with high support performance.

  The invention according to claim 1 for solving the above-mentioned problem is a field edge for fixing a field edge arranged in a grooved shape with a lip on the lower side of the field edge receiver so that the groove opening faces upward. In the fixing clip, a field edge connecting portion connected to the field edge, and a field edge receiving connection portion integrally formed with the field edge connecting portion and connected to the field edge receiving portion, the field edge connecting portion, Locking means provided with locking plate portions that support the lip portion of the field edge from below at both ends in the width direction of the narrow plate portion narrower than the groove opening width of the field edge, and the narrow plate portion integrated And a cover plate comprising a hanging plate portion that covers the side surface portion of the field edge on a wide plate portion that is flush with the width of the field edge and is flush with the field edge. .

  According to such a configuration, the field edge connecting portion and the field edge receiving connection portion are integrally formed, so that the number of parts is small and attachment to the field edge can be easily performed. In addition, since the locking means and the cover means are integrally formed, the lip part of the field edge can be supported from the lower side with one member and the side surface part of the field edge can be held down, improving the field edge support performance. Can be made.

  In the invention according to claim 2, the locking means is provided at a proximal end portion of the field edge connection portion near the field edge receiving connection portion, and the cover means is provided at a distal end portion of the field edge connection portion. The hanging plate portion is characterized in that a lower end edge portion is inclined so that a hanging length on the locking means side is shortened.

  When fixing the field edge fixing clip having such a configuration to the field edge, first, the cover means is raised so that the locking means is at the bottom, and the narrow plate portion of the locking means is the edge of the field edge. Inserted from the groove opening in an oblique state with an angle with the width direction, and rotated so that the narrow plate part is in the same direction as the width direction of the field edge with the locking plate part in the field edge . Thereafter, the field edge connection portion with the cover means facing upward is leveled and returned to the field edge, and the side surface portion of the field edge is covered with the hanging plate portion. Here, since the lower end edge part of the hanging plate part is inclined, it is easy to work without interfering with the field edge when rotating the field edge fixing clip.

  The invention according to claim 3 is characterized in that a penetrating hole is formed in the hanging plate part.

  According to such a configuration, if the hanging plate portion is fixed to the side surface portion of the field edge through screws or screws through the through hole, the field edge support performance is further improved.

  Further, the invention according to claim 4 is characterized in that the field edge receiving connection part is bent from the edge connection part and is bent from the upper end of the rising edge part so as to surround the field edge receiver from above. And a bent portion is formed at a distal end portion of the hanging plate portion, and the bent portion extends to a proximal end side of the hanging plate portion and rises up. The lever plate material which protrudes from the surface of the plate portion is formed to be flush with each other.

  According to such a configuration, the bent plate portion is bent while pushing the lever plate material using the lever principle in a state where the hanging plate portion is placed on the edge receiver, but by providing the lever plate material, Since the distance between the fulcrum and the force point can be increased, even if the plate thickness of the field edge fixing clip is thick, it can be easily folded by a worker without using a special jig. And since a field edge holder is pinched | interposed by a standing board part and a bending part, the fixing performance to the field edge receiver of a field edge fixing clip improves. Further, when the field edge fixing clip is attached to the field edge receiver, the lever plate material is raised, so that when the ceiling base material is looked up from below, it can be easily confirmed whether or not it is attached.

  Further, in the invention according to claim 5, both sides in the width direction of the rising plate portion are recessed inward, and the width between the lower end portion and the upper end portion of the rising plate portion is wider than the lower end portion and the upper end portion. It is characterized by being configured to be narrow.

  According to such a configuration, the width between the lower end portion and the upper end portion of the rising plate portion is narrower than that of the lower end portion and the upper end portion. When the narrow plate portion is rotated so as to be in the same direction as the width direction of the field edge, the rising plate portion and the lip portion of the field edge are less likely to interfere with each other, and the rotation is facilitated.

  The invention according to claim 6 is characterized in that the base end portion of the bent portion is narrower than the base end portion of the hanging plate portion.

  According to such a configuration, since the bending length of the bent portion can be shortened, the force required for bending the bent portion can be reduced, and the bending work can be easily performed. This configuration is particularly effective when the width of the field edge is large and the width of the rising plate portion and the hanging plate portion is wide.

  Further, the invention according to claim 7 is characterized in that the field edge receiving connection part is bent from the field edge connection part and is bent from the upper end of the rising plate part so as to surround the field edge receiver from above. And a projecting portion for holding the edge of the upper end surface of the field edge receiver is provided at the tip of the hanging plate part, and the rising edge is provided with the edge receiver. A spring plate portion inclined to the side is provided.

  According to such a configuration, when the field receiver is inserted into the lower part of the hanging plate part, one surface of the field receiver is locked to the convex part, and the other surface is biased to the convex part side by the spring plate part. Therefore, the field edge receiver is clamped, and the fixing performance of the field edge fixing clip to the field edge receiver is improved.

  The field edge fixing clip according to the present invention exhibits an excellent effect that the field edge can be fixed easily with high support performance.

(First embodiment)
A procedure for attaching a field edge fixing clip and a field edge and a field edge receiver according to the first embodiment of the present invention will be described in detail with reference to the drawings. In the description, the same reference numerals are used for the same elements, and duplicate descriptions are omitted.

  As shown in FIGS. 1 and 2, the field edge fixing clip 1 according to this embodiment is for fixing a field edge 90 to the lower side of the field edge receiver 80. Although only a single field edge receiver 80 and field edge 90 are illustrated, each of the field edge receivers 80 and the field edge 90 is arranged in parallel and arranged so as to be in a lattice shape orthogonal to each other in plan view.

  As shown in FIG. 1, the field edge receiver 80 is made of grooved steel having a U-shaped cross section, and is arranged so that the groove opening is in a horizontal direction. The field edge receiver 80 is configured by integrally forming a web 81 arranged vertically, a lower flange 82 and an upper flange 83 arranged horizontally. The field edge 90 is comprised with the grooved steel with a lip, and is arrange | positioned so that the groove opening may become upward. The field edge 90 is configured by integrally forming a bottom surface portion 91, a pair of side surface portions 92, 92, and a pair of lip portions 93, 93. The lip portion 93 enters the inner side in the width direction from the side surface portion 92, and its tip end portion is bent toward the bottom surface portion 91 side and hangs down. The sizes of the field edge receiver 80 and the field edge 90 conform to JIS standards and are appropriately selected according to various conditions such as the size and weight of the ceiling.

  As shown in FIGS. 1 and 2, the field edge fixing clip 1 includes a field edge connection part 10 and a field edge receiving connection part 50. The field edge connecting portion 10 and the field edge receiving connection portion 50 are made of a single metal plate, and are integrally formed by performing various processes such as cutting, bending, and punching. The field edge connecting portion 10 is a portion connected to the field edge 90 and includes a locking means 11 and a cover means 31. The locking means 11 is provided at the base end portion of the field edge connection portion 10 near the field edge receiving connection portion 50, and the cover means 31 is provided at the distal end portion of the field edge connection portion 10.

  The locking means 11 is a part that locks the lip 93 from below. The locking means 11 is a locking plate portion 13 that supports the lip portions 93 of the field edge 90 from below at both ends in the width direction of the narrow plate portion 12 having a width dimension W1 narrower than the groove opening width S1 of the field edge 90. Are provided respectively. The locking plate portion 13 is inserted inside the field edge 90. The locking plate portion 13 includes a hanging portion 13a that extends downward from both ends of the narrow plate portion 12, and a folded portion 13b that extends outward from the lower end in the width direction and faces upward. The tip of the folded portion 13b enters the inside of the lip portion 93 (see (c) in FIG. 2). The tip of the folded portion 13b is inclined and tapered. In addition, in this embodiment, although the front-end | tip of the folding | turning part 13b has faced upwards, it is not the meaning limited to this, The shape which only spreads in the width direction outer side may be sufficient.

  The cover means 31 is a part which covers from the upper side of the field edge 90 and covers the side surface portions 92, 92 of the field edge 90 from the outside. The cover means 31 is provided with a hanging plate portion 33 on a wide plate portion 32 that is integral with the narrow plate portion 12 and has the same width dimension W2 as the width S2 of the field edge 90. The hanging plate portion 33 is provided at both ends in the width direction of the wide plate portion 32 so as to be parallel to the longitudinal direction of the field edge 90 to be attached. The hanging plate portion 33 is bent at a substantially right angle with respect to the wide plate portion 32. The lower end edge of the hanging plate part 33 is inclined so that the hanging length on the locking means 11 side (base end side) is shortened. This is to improve the installation workability of the field edge fixing clip 1 to the field edge 90. The installation work will be described later. The inclined surface of the lower end edge portion of the hanging plate portion 33 and the inclined surface of the distal end portion of the folded portion 13b of the locking plate portion 13 are substantially parallel. In addition, if it is a state close | similar to parallel, it does not need to be parallel. The distance S3 (see FIG. 2B) between the line extending the lower end edge of the hanging plate portion 33 and the line extending the inclined surface of the tip of the folded portion 13b of the locking plate portion 13 is The dimension is slightly larger than the height of the lip portion 93 of the edge 90.

  A through hole 34 is formed in the hanging plate portion 33. The through hole 34 is for inserting a fixing member such as a screw. The fixing member is driven into the side surface portion 92 of the field edge 90 from the hanging plate part 33 side, and the field edge 90 is attached to the field edge fixing clip 1. Used when fixing.

  The field edge receiving connection part 50 includes a rising plate part 51 that is bent from the field edge connection part 10 and a hanging plate part 61 that is bent from the upper end of the rising plate part 51 and surrounds the field edge receiving 80 from above.

  The rising plate portion 51 is bent at a right angle continuously from the narrow plate portion 12 and becomes vertical when in use. The rising plate portion 51 is formed with a wide upper portion for strength improvement. The width of the upper portion is appropriately selected according to the size of the field edge receiver 80, the weight of the field edge 90, and the mounting pitch of the field edge fixing clip 1. A through hole 52 is formed in the rising plate portion 51. The through hole 52 is for inserting a fixing member such as a screw. The fixing member is driven into the web 81 of the field edge receiver 80 from the rising plate portion 51 side, and the field edge fixing clip 1 is inserted into the field edge receiver 80. Used when fixing. The upper end portion of the rising plate portion 51 is formed with a notch 53 at the center in the width direction, and is connected to the hanging plate portion 61 in a bifurcated shape. The notch 53 is a portion cut to form a lever plate 63 described later.

  The hanging plate portion 61 is bent at a right angle continuously from the rising plate portion 51 and becomes horizontal during use. The hanging plate part 61 is bent to the opposite side to the field edge connecting part 10. The base end portion of the hanging plate portion 61 is connected to the upper end portion of the rising plate portion 51 and has a bifurcated shape. A bent portion 62 is formed at the tip of the hanging plate portion 61. The bent portion 62 is formed so as to connect the ends of the bifurcated portions. The bent portion 62 is a portion for vertically bending the field edge receiver 80 after it is set and sandwiching the field edge receiver 80 from both sides in the horizontal direction together with the rising plate part 51. The bent portion 62 is provided with a lever plate 63 integrally. The lever plate material 63 is a part that is gripped and pushed up by hand when the bent portion 62 is bent. The lever plate material 63 is disposed between the forked portions of the base end portion of the hanging plate portion 61. The lever plate member 63 extends to the proximal end side of the hanging plate portion 61 and protrudes to the opposite side of the bent portion 62 from the surface of the rising plate portion 51. The surface of the lever plate 63 is flush with the surface of the bent portion 62. The lever plate 63 is formed with reinforcing ribs 64 that swell upward. The reinforcing rib 64 is formed to extend from the vicinity of the distal end portion of the lever plate member 63 to the bent portion 62.

  A through hole 67 is formed in the bent portion 62. The through hole 67 is for inserting a fixing member such as a screw, and is used when the fixing member is driven into the field edge receiver 80 and the field edge receiver 80 is fixed to the field edge fixing clip 1. In addition, since the field edge receiver 80 of this embodiment is U-shaped in cross section and the bent portion 62 is located in the opening portion, the through hole 67 is not used, but in the case of a square pipe-shaped field edge receiver, A through hole 67 may be used.

  A bending guide groove 65 is formed at the base end portion of the folding portion 62 (in the vicinity of the end portion position of the upper flange 83 of the field receiver 80), which is a folding line of the hanging plate portion 61. The bending guide groove 65 is formed on the upper surface of the hanging plate portion 61 so as to have a V-shaped cross section or a U-shaped cross section.

  Next, with reference to FIG. 3, a construction procedure when the field edge 90 is fixed to the field edge connection portion 10 of the field edge fixing clip 1 having such a configuration will be described.

  First, as shown in FIG. 3A, the cover means 31 is lifted obliquely upward so that the locking means 11 is on the lower side, and the narrow plate portion 12 and the rising plate portion 51 are V-shaped. Like that. Then, in order to prevent the locking plate portion 13 from interfering with the lip portion 93 of the field edge 90, the width direction of the narrow plate portion 12 of the locking means 11 intersects the width direction of the field edge 90, and the field edge fixing clip 1 is positioned on the field edge 90. In the present embodiment, the locking plate portion 13 is rotated by 90 degrees so that the locking plate portion 13 extends along the longitudinal direction of the field edge 90, but is not limited to 90 degrees. The angle does not matter as long as it does not interfere with the portion 93. In this state, the field edge fixing clip 1 is lowered and the locking plate portion 13 is inserted inside the field edge 80.

  Thereafter, as shown in FIG. 3B, the field edge fixing clip 1 is rotated so that the cover means 31 is located at the upper part of the field edge 90. As a result, the folded portion 13 b at the tip of the locking plate portion 13 enters the lower side of the lip portion 93. At this time, since the lower end edge portion of the hanging plate portion 33 is inclined, it is difficult to interfere with the upper end of the lip portion 93 of the field edge 90, so that the rotation can be performed smoothly. Further, since the tip end portion of the folded portion 13 b of the locking plate portion 13 is inclined and tapered, the locking plate portion 13 is less likely to interfere with the lower end of the lip portion 93. Further, a distance S3 (see FIG. 2B) between a line extending the lower end edge of the hanging plate portion 33 and a line extending the inclined surface of the distal end portion of the folded portion 13b of the locking plate portion 13 is obtained. Since the size is slightly larger than the height of the lip portion 93, the lip portion 93 can pass therethrough and the field edge fixing clip 1 can be reliably rotated.

  Then, as shown in FIG. 3C, the rising plate portion 51 is raised so as to be perpendicular to the field edge 90. Then, the cover means 31 contacts the field edge 90, and the hanging plate part 33 covers the side surface parts 92, 92 of the field edge 90 from the outside. Thus, the mounting of the field edge fixing clip 1 to the field edge 90 is completed.

  Here, since the hanging plate portion 33 covers the side surface portions 92, 92 of the field edge 90 from the outside, the field edge fixing clip 1 and the field edge 90 do not rotate with each other. As a result, the leading edge of the locking plate portion 13 does not deviate from the lower side of the lip portion 93 and the field edge 90 can be reliably supported, so that the support performance of the field edge 90 is greatly improved. Become. Further, the field edge 90 comes into contact at a plurality of locations of the locking means 11 and the cover means 31 and is thus supported in a stable state.

  Even in this state, the support performance of the field edge 90 by the field edge fixing clip 1 is high, but if the field edge 90 is screwed using the through hole 34 of the hanging plate part 33, the support performance is further improved. Can be improved. If the screw fixing is performed at a position where a lot of force is applied, such as in the vicinity of the connecting portion of the ceiling brace, the seismic force can be transmitted to the ceiling brace and the displacement of the ceiling material can be suppressed. Moreover, if the said screw fixation is performed in the ceiling peripheral part used as the vicinity of a wall, the shift | offset | difference of a ceiling material can be suppressed and it can suppress that a ceiling material collides and interferes with a wall surface.

  Next, with reference to FIG. 4, a construction procedure for fixing the field receiver 80 to the field receiver connection portion 50 will be described.

  First, as shown in FIG. 4A, the field edge fixing clip 1 and the field edge 90 are moved so that the rising plate portion 51 contacts the web 81 of the field edge receiver 80. At this time, the lower flange 82 of the field edge receiver 80 is in contact with the upper surface of the field edge 80 and the upper flange 83 is in contact with the lower surface of the hanging plate portion 61. Then, the operator holds the tip of the lever plate 63 and lifts it up in an arc shape with the tip of the upper flange 83 (the right end in FIG. 4A) as a fulcrum.

  Then, as shown in FIG. 4B, the bent portion 62 that rotates integrally with the lever plate material 63 is bent, and the field edge receiver 80 is formed by the rising plate portion 51 and the bent portion 62. It is pinched and fixed. Here, the fixing of the field edge fixing clip 1 to the field edge receiver 80 is completed. The bent portion 62 is bent downward about the tip of the upper flange 83. In other words, the folding part 62 is folded using the lever principle in a state where the hanging plate part 61 is placed on the field receiver 80, but by providing the lever plate material 63, the distance between the fulcrum and the force point is increased. Can be made longer. Thereby, even if the plate | board material of the field edge fixing clip 1 is thick, it can be easily bent by an operator's human power, without using a special jig | tool. Further, since the reinforcing rib 64 is formed on the lever plate 63, it is possible to cope with a strong stress. Furthermore, since the guide groove 65 is formed, the bending position can be easily determined and the bent portion 62 can be bent beautifully.

  Since the field edge receiver 80 is sandwiched between the rising plate part 51 and the bent part 62, the fixing performance of the field edge fixing clip 1 to the field edge receiver 80 is improved. Further, since the field edge receiver 80 is also sandwiched between the hanging plate portion 61 and the field edge 90, the performance of fixing the field edge fixing clip 1 to the field edge receiver 80 is further improved. Furthermore, when the field edge fixing clip 1 is attached to the field edge receiver 80, the lever plate material 63 is raised. Therefore, when the ceiling base material is looked up from below or when the ceiling base material is seen from the scaffold, it can be easily confirmed visually whether or not the mounting operation is completed.

  As described above, according to the field edge fixing clip 1 of the present embodiment, the field edge connection part 10 and the field edge receiving connection part 50 are integrally formed. Installation to the edge receiver 80 can be performed easily. Specifically, the field edge 90 can be easily fixed to the field edge connection part 10 simply by inserting the locking plate portion 13 into the field edge 90 and rotating the field edge fixing clip 1 to get up. . Further, since the locking means 11 and the cover means 31 are integrally formed, the lip portion 93 of the field edge 90 can be supported from the lower side and the side surface portion 92 of the field edge 90 can be pressed by one member. The edge fixing clip 1 can be prevented from rotating, and the support performance of the field edge 90 can be improved.

  In addition, by tilting the lower end edge of the hanging plate portion 33, when the field edge fixing clip 1 is rotated, it does not interfere with the field edge 90 and is easy to work. Furthermore, since the hanging plate part 33 is not made smaller than necessary, the strength of the cover means 31 can be secured.

  Further, when the field edge fixing clip 1 is fixed to the field edge receiver 80, the field edge fixing clip 1 is horizontally moved while being engaged with the field edge 90, and the rising plate portion 51 and the field edge receiver 80 are brought into contact with each other and folded. Since the bending part 62 should just be bent, it can respond to either a new ceiling or an existing ceiling.

(Second embodiment)
A field edge fixing clip according to a second embodiment of the present invention will be described in detail with reference to the drawings. The field edge fixing clip 1 according to the second embodiment is different from the first embodiment in the structure of the field edge receiving connection part 50 ′. In addition, since the structure of the field edge connection part 10 is the same as that of 1st embodiment, it attaches | subjects the same code | symbol and abbreviate | omits description.

  As shown in FIGS. 5 and 6, the field edge connection part 50 ′ is bent upward from the rising edge part 51 ′ bent from the field edge connection part 10 and the upper edge of the rising edge part 51 ′. And a hanging plate portion 61 ′ that surrounds.

  The rising plate portion 51 ′ is bent at a right angle continuously from the narrow plate portion 12 and becomes vertical when in use. The rising plate portion 51 ′ has a wide upper portion. The width of the upper portion is appropriately selected according to the size of the field edge receiver 80, the weight of the field edge 90, and the mounting pitch of the field edge fixing clip 1. A through hole 52 similar to that of the first embodiment is formed in the rising plate portion 51 ′. A U-shaped opening 54 is formed in the upper portion of the rising plate portion 51 ', and the plate material is left inside. This plate material is bent so that the tip portion protrudes toward the arrangement side of the field edge receiver 80 to form a spring plate portion 55. That is, when the field edge receiver 80 is installed, the spring plate part 55 is pushed back to the rising plate part 51 ′ side by the web 81 of the field edge receiver 80. The web 81 of the receiver 80 is elastically biased.

  The hanging plate portion 61 ′ is bent at a right angle continuously from the rising plate portion 51 ′ and becomes horizontal during use. The hanging plate portion 61 ′ is bent on the side opposite to the field edge connecting portion 10. Cutout portions 68 are formed at both ends in the width direction of the hanging plate portion 61. The notch 68 has a rectangular shape in plan view. Each notch portion 68 is formed at a position away from the base end portion of the hanging plate portion 61 ′ by a dimension substantially equal to the width dimension of the upper flange 83 of the field edge receiver 80.

  The plate material on the front end side of the notch 68 is bent. Specifically, the plate material is bent downward so that a straight line connecting the corner at the back of the notch 68 and the corner at the tip of the hanging plate 61 'becomes a folding line. As viewed from the side, the bent portion 69 is gradually lowered as the lower end surface moves toward the rising plate portion 51 ′. The bent portion 69 protrudes downward from the hanging plate portion 61 ′ and constitutes a convex portion that holds down the edge portion of the upper end surface of the field receiver 80 (the front end surface of the upper flange 83). Of the peripheral edge portion of the bent portion 69, the cut surface portion of the notch portion 68 abuts against the distal end surface of the upper flange 83, thereby pressing the edge receiver 80.

  Next, with reference to FIG. 7, a construction procedure for fixing the field receiver 80 to the field receiver connection portion 50 'will be described.

  First, as shown in FIG. 7A, the field edge fixing clip 1 and the field edge 90 are moved so that the rising plate portion 51 ′ approaches the web 81 of the field edge receiver 80. At this time, first, the distal end portion of the hanging plate portion 61 ′ comes into contact with the base end surface of the upper flange 83 of the field edge receiver 80, but the field edge fixing clip 1 is further pushed. Then, since the lower end surface of the bent portion 69 is inclined, the hanging plate portion 61 ′ is gradually pushed up by the upper flange 83 of the field edge receiver 80 and is warped elastically.

  Then, as shown in FIG. 7B, when the bent portion 69 (convex portion) passes through the upper flange 83, the warped hanging plate portion 61 ′ returns to its original shape, and the bent portion The peripheral edge portion 69 holds the front end surface of the upper flange 83 of the field edge receiver 80. This completes the fixing of the field edge fixing clip 1 to the field edge receiver 80. At this time, the web 81 is in contact with the rising plate portion 51 ′, and the spring plate portion 55 is pushed back toward the rising plate portion 51 ′. Therefore, the field edge receiver 80 is elastically biased toward the bent portion 69 by the restoring force of the spring plate portion 55, so that it is sandwiched and fixed between the bent portion 69 (convex portion) and the spring plate portion 55. The

  According to the field edge fixing clip 1 according to the present embodiment, substantially the same operational effects as the first embodiment can be obtained. In particular, according to the field edge receiving connection portion 50 ′, the field edge fixing clip 1 can be fixed to the field edge receiver 80 only by moving the field edge fixing clip 1 horizontally.

(Third embodiment)
A field edge fixing clip according to a third embodiment of the present invention will be described in detail with reference to the drawings. The field edge fixing clip 1 according to the third embodiment is different from the first embodiment in the structure of the field edge receiving connection portion 50 ". In the third embodiment, the field edge 90 is described as an example having a wide width. Since the configuration of the field edge connecting portion 10 is the same as that of the first embodiment except for the wide width, the same reference numerals are given and description thereof is omitted.

  As shown in FIG. 8, the field edge connection part 50 ″ is suspended from the upright plate part 51 ″ bent from the field edge connection part 10 and bent from the upper end of the rising edge part 51 ″ to surround the field edge receiver 80 from above. And a hanging plate portion 61 ″. Similarly to the field edge connection part 10, the field edge receiving connection part 50 ″ is formed wider than the first embodiment in accordance with the width of the field edge 90.

  The rising plate portion 51 "is continuously bent from the narrow plate portion 12 at a right angle and becomes vertical when in use. The rising plate portion 51" has a shape in which both sides in the width direction are recessed inward, The width between the lower end portion and the upper end portion of the rising plate portion 51 ″ is configured to be narrower than that of the lower end portion and the upper end portion. The width is once narrowed, and the width is increased from the narrow portion toward the upper end portion. Both sides in the width direction of the rising plate portion 51 ″ are cut in a chevron shape. The portion having the largest cut amount on both sides in the width direction of the rising plate portion 51 ″ (hereinafter, referred to as “narrow portion 56” may be referred to. ), In the step of fixing the field edge fixing clip 1 to the field edge 90, when the narrow plate part is rotated in the same direction as the width direction of the field edge with the locking plate part in the field edge. In addition, the rising plate portion 51 ″ is a portion approaching the lip portion 93 of the field edge 90 (a portion that easily comes into contact). The upper end portion of the rising plate portion 51 ″ has the same width as the lower end portion.

  The hanging plate portion 61 ″ is bent at a right angle continuously from the rising plate portion 51 ″ and becomes horizontal during use. As in the first embodiment, the hanging plate portion 61 ″ has a bifurcated shape with the base end portion connected to the upper end portion of the rising plate portion 51, and a bent portion 62 is formed at the distal end portion thereof. The bent portion 62 is formed so as to connect the tips of the bifurcated portions.The base end portion of the hanging plate portion 61 ″ has the same width as the upper end portion of the rising plate portion 51 ″. Thus, the width becomes narrower toward the bent portion 62. Accordingly, the folding line of the hanging plate portion 61 (the width of the base end portion of the bent portion 62) is shortened.

  Reinforcing ribs 20 (shown only for the field edge connection part 10) are formed on the narrow plate part 12 and the wide plate part 32 of the field edge connection part 10 and the rising plate part 51 "of the field edge receiving connection part 50". May be. The reinforcing rib 20 is formed to extend from the narrow plate portion 12 of the field edge connecting portion 10 to the wide plate portion 32. When the reinforcing rib is formed on the rising plate portion 51 ″ of the field edge receiving connection portion 50 ″, it is preferably formed so as to pass through the narrow portion 56.

  According to the field edge fixing clip 1 according to the third embodiment, by forming the narrow part 56 in the rising plate part 51 ", the locking plate part 13 is in the field edge 90 as shown in FIG. When the field edge fixing clip 1 is rotated in this state, the rising plate portion 51 ″ and the lip portion 93 of the field edge 90 are less likely to interfere with each other and can be easily rotated, thereby facilitating the work.

  Further, since the base end portion of the bent portion 62 is made narrower than the base end portion of the hanging plate portion 61 ″, the bent length of the bent portion 62 can be shortened. Can be reduced, and the bending work can be easily performed.
