Description

  The present invention relates to a pole mounting bracket for mounting an electric / electronic device or an electric / electronic device storage box on which the electric / electronic device is mounted on a utility pole or other poles.

  As the pole mounting bracket, as shown in FIG. 11, the mounting bracket 100 for mounting an electric / electronic device storage box or the like is provided with a concave arc-shaped receiving portion 101 corresponding to the pole diameter. It is known that both ends of a band 102 around which a pole (I) is wound are temporarily fixed with bolts and nuts 103 and then bolts and nuts 103 are firmly tightened and fixed. However, this is only the extent that the band 102 is simply hooked to the pole at the time of temporary fixing, and for tightening the bolt, the tightening distance of the bolt 103 and the nut 103 is long, and the number of times that the bolt is rotated is large and the workability is poor. . In addition, since the bolt 103 cannot be firmly tightened unless it is at a small angle that is tangential to the band 102, a large-diameter pole (A-1) as shown in FIG. When the diameter mounting bracket 100 is used, the angle between the band and the bolt becomes large, so that accurate mounting is impossible. Therefore, as shown in FIGS. 11A and 11C, it is necessary to manufacture the mounting bracket 100 including the receiving portion 101 for each pole having a different diameter, which increases the cost.

Therefore, the applicant has proposed a pole mounting bracket shown in Patent Document 1 that can be used for various pole diameters, but this is merely the extent that the band is simply hooked on the pole during temporary fixing. In the subsequent final tightening, the tightening distance of the bolt and nut is long, and the number of times the bolt is rotated is large, so that the workability is poor.

Therefore, if the hook portion is locked with a locking hole that is located in the hook portion provided in the window hole among the many locking holes of the band, it can be strongly fixed temporarily. . After that, if the bolt is advanced and rotated and the fastening member is slid, the band portion extending from the front opening to the hook portion is pressed by the fastening member and the band is extended, so that the main fastening can be strongly performed. Since the fastening can be performed firmly, the number of rotations of the bolt is small and the workability is excellent. In this case, since the band is bent in a V shape with the fastening member as a fulcrum, the tightening operation is performed in two directions around the fastening member, so that the advancing rotation distance of the bolt can be reduced and the fastening bracket body is The size of the bolt in the longitudinal direction can be reduced.

  In addition, it is assumed that a locking hole is provided over the entire length of the band, and that the locking part for fixing the base end side of the band of the fastening bracket body is made of a hook part, and the locking hole on the base end side of the band is attached and detached. Even if a long band is used for a small-diameter pole, the hook hole corresponding to the pole diameter is locked to the hook from the base end side of the band. The part left at the base end can be installed without inconvenience of touching many things by sandwiching it between the front side of the band and the pole, so it can handle poles of various diameters just by preparing a long band It is.

Next, a preferred embodiment of the present invention will be described with reference to the drawings.
Reference numeral 1 denotes a fastening metal fitting body. The fastening metal fitting body 1 is formed by connecting left and right side plate portions 12 and 13 in front of both side edges of the back plate portion 11 and connecting the upper plate in front of the upper edge of the back plate portion 11. The part 14 is formed in a square box shape by bending the lower plate part 15 in front of the lower edge. Then, the front opening side, that is, the front edge of the upper plate portion 13 and the lower plate portion 14 is formed as a concave shape, and two points at both ends of each concave shape are formed in the pole receiving portion 2 that contacts the pole (A).

  Further, as shown in FIGS. 1 and 2, a base of a band 3 for winding a pole in which a large number of locking holes 31 are arranged at a predetermined interval on one side of the fastening metal fitting body 1, that is, the right side plate 13. A locking portion 4 for fixing the end side is provided as a hook portion 4 which is bent inwardly at the inner edge on the front side of the window hole 13 a provided in the side plate portion 13. The locking hole 31 on the base end side can be detachably fixed. Further, as shown in FIGS. 6 and 7, a window hole 11 a formed in the back plate part 11 after being inserted into the fastening metal body 1 from the front side opening near the other side of the fastening metal body 1, that is, the left side plate part 12. A hook portion 5 that locks the locking hole 31 on the distal end side of the band 3 protruding from the outside is bent at the inner edge of the window hole 11a near the left side plate portion 12.

  Reference numeral 6 denotes a fastening member that slides by advancing rotation of the bolt 7, and the fastening member 6 faces the band 3 at a location located between the front opening and the hook portion 5 in the fastening metal body 1. Further, a position closer to one side of the fastening metal body 1 than the hook portion 5, that is, the left side plate portion 12 is provided as a standby position.

  The tightening member 6 has a cylindrical shape, and as means for making it slidable, the rail long holes 8 and 8 are arranged at the front and rear centers so as to face the upper plate portion 14 and the lower plate portion 15. The upper plate portion 14 and the lower plate portion 15 are provided on the outer sides of the upper plate portion 14 and the lower plate portion 15 by fitting the elongated holes 8 and 8 with projections 61 and 61 protruding from the upper and lower ends of the cylindrical fastening member 6. Screwed through a washer. In addition, as shown in FIG. 6, the upper and lower ends of the fastening member 6 having a columnar shape have circular arcs at the periphery, so that a washer or the like is provided between the upper and lower ends of the fastening member 6 and the inner surface of the upper plate portion 13 and the lower plate portion 14. It can be easily mounted and manufactured without rattling up and down without intervening inclusions. As shown in FIG. 3, the bolt 7 is screwed into a female screw portion 7 a provided on the left side plate portion 12, and rotates forward so that the tip presses the fastening member 6, which will be described later by the fastening member 6. The band 3 can be finally tightened.

  Further, as shown in FIG. 6, a recess 62 in which the tip of the bolt 7 is fitted is provided in the fastening member 6 so that the tip of the bolt 7 is surely pressed against the cylindrical fastening member 6. The projecting portions 61 and 61 are formed in a square shape so that the fastening member 6 does not rotate around the projecting portions 61 and 61 so as to face the tip of the bolt 7. In addition, as shown in FIG. 7, the fastening member 6 may be attached to the U-shaped holder 9 so that the upper and lower ends thereof are rotatable, and the holder 9 is provided in the fastening hardware body 1 by the sliding means as described above. Further, the structure of the fastening member 6 is not limited as long as the contacting band 3 slides, and may be a polygonal columnar shape or a columnar shape in which only the contact portion is an arc.

  What is configured in this manner is that the pole receiving portions 2 formed on both end sides of the front plate opening side upper plate portion 14 and the lower plate portion 15 of the square box-shaped fastening bracket body 1 are formed in the concave shape. Since it is in contact with (a), it can cope with various poles having a diameter or more that do not fit into the concave shape. Then, the pole receiving portion 2 is brought into contact with the pole (A) in this way and is bent inward to the inner edge of the front side of the window hole 13a provided in one side portion of the fastening metal fitting body 1, that is, the right side plate portion 13. The front end side of the band 3 for winding the pole, the base end side of which is fixed to the engaging portion 4 provided as the hook portion formed, is close to the other side portion of the fastening metal body 1, that is, the left side plate portion 12, that is, the left side. FIG. 8 shows a window hole 11a formed in the back plate portion 11 after being inserted into the fastening metal fitting body 1 through a guide hole 12b provided in a bent piece portion 12a formed at the front end of the plate portion 12 toward the front opening. Pull it out like so.

  Then, the fastening member 6 that slides by the forward rotation of the bolt 7 is hooked to the position where the belt in the place between the front opening and the hook part 5 bent in the window hole 11a faces in the fastening body 1. Since the position closer to one side of the fastening bracket body than the portion 5, that is, the left side plate portion 12 is provided as a standby position, the band 3 can be tightened like a belt buckle with the fastening member 6 as a fulcrum, Of the numerous locking holes 31 of the band 3, the locking holes 31 that are to be located in the hook portions 5 provided in the window holes 11 a can be strongly temporarily fixed by locking the hook portions.

  Thereafter, as shown in FIG. 9, when the bolt 7 is advanced and rotated and the fastening member 6 is slid to the right side plate portion 13 side, the band located between the front opening and the hook portion 5 is tightened. Since the band 3 is pressed by the member 6 and stretches, it can be strongly tightened, and since the temporary fixing can be firmly performed, the number of times that the bolt is rotated is small and the workability is excellent. Then, as shown in FIG. 1, attach a separate equipment mounting bracket (B) to the band 3 and attach an electrical equipment storage box (C) to the equipment mounting bracket (B), or tighten as shown in FIG. An electrical equipment storage box (c) can be directly attached to the metal fitting body 1. Further, since the band 3 is bent in a V shape with the fastening member 6 as a fulcrum, the fastening operation is performed in two directions around the fastening member 6, so that the advancing rotation distance of the bolt 7 can be reduced and the fastening is performed accordingly. The left and right sizes, which are the longitudinal direction of the bolts of the metal fitting body 1, can be reduced.

  Further, when the standby position of the fastening member 6 is close to the left side plate portion 12, the V-shaped angle of the band having the fastening member 6 as a fulcrum is large, and the fastening member 6 bolt can be rotated with a small torque, while the number of times of rotation is small. On the contrary, when the standby position of the fastening member 6 is a position away from the left side plate portion 12, the V-shaped angle of the band with the fastening member 6 as a fulcrum becomes small, and the bolt must be rotated with a large torque. Although it is not necessary, it is possible to fasten the band quickly because only a few rotations are required. Therefore, the standby position of the fastening member 6 may be set according to workability and the weight of the electrical equipment storage box to be attached.

  When the band 7 is finally tightened by moving the bolt 7 forward and sliding the fastening member 6 toward the right side plate part 13, a force spreading outward is applied to the left and right side plate parts 12 and 13 due to the reaction. 4 and 5, the extension piece portions 14 c and 15 c on both sides of the upper plate portion 14 and the lower plate portion 15 are bent so as to contact the upper and lower outer surfaces of the left and right side plate portions 12 and 13. Thus, it can sufficiently withstand the force spreading outward and can be manufactured at low cost without the need for welding.

  Further, the base end of the band 3 is assumed to be provided with a locking hole 31 over the entire length of the band 3, and the locking portion 4 for fixing the base end side of the band 3 of the fastening metal fitting 1 is formed of the hook portion 4. Even if the long band 3 is used for a small-diameter pole, it corresponds to the diameter of the pole from the base end side of the band 3 by detachably locking the side locking hole 31. The portion left at the base end after the locking hole 31 is locked to the hook portion 4 is projected from the front opening of the fastening bracket body 1 and is held between the front side of the band 3 and the pole to touch many things. Therefore, it is possible to deal with poles of various diameters simply by preparing a long band 3.
