  However, in the conventional pedestrian signal lamp mounting bracket described in Patent Document 1 described above, the connection between the tubular arm bracket side bracket and the signal lamp bracket is connected to the arm bracket outside the cylinder portion of the signal lamp bracket. Since the side metal fittings are covered with a set of fastening bolts and nuts, the fastening force (tightening force) is strong at the parts close to the fastening bolts and nuts. However, the fastening force (clamping force) decreases with increasing distance from the fastening bolt and nut.

  Therefore, in the conventional pedestrian signal lamp mounting bracket, when strong wind hits the pedestrian signal lamp mounting bracket, there is a risk that the pedestrian signal lamp will rotate at the connecting part between the arm bracket side bracket and the signal lamp bracket. There is a problem that there is.

  In particular, when fastening bolts and nuts are loosened due to secular change, or when the fastening bolts and nuts themselves deteriorate, the pedestrian signal lamp may rotate due to strong winds or the like.

  In addition to the fastening bolts and nuts, a tubular arm bracket side bracket and signal lamp side bracket are required between the arm bracket and the pedestrian signal lamp, so the number of parts is large and the weight of the bracket itself is large. As a result, there has been a problem that the mounting work is troublesome.

  Therefore, the present invention has been made paying attention to such problems, and it is difficult for the pedestrian signal lamp to rotate due to strong winds, etc., and the number of parts including the fastening bolts and nuts is reduced to reduce the number of parts. An object of the present invention is to provide a pedestrian signal lamp mounting bracket capable of reducing the weight and improving the mounting workability of the signal lamp.

In order to solve the above-described problem, the method for manufacturing a pedestrian signal lamp mounting bracket according to an embodiment of the present invention is configured such that one end side is connected to two braces extending from a support pole such as a power pole at regular intervals in the vertical direction. On the other hand, the other end side is connected to the upper or lower part of the pedestrian signal lamp, and is a pedestrian signal lamp mounting bracket for mounting the pedestrian signal lamp on a pole such as a utility pole, with one end on the arm While having a brace connecting part to be connected to gold, the other end side is a signal lamp side and has a skirt part whose front end part is spread outward, and the arm metal part is connected between the brace part and the skirt part. A cylindrical main body portion having a relay cylinder portion bent from the direction toward the direction of the signal lamp, and the outer diameter of the intermediate cylinder portion of the cylindrical main body portion and outside the skirt portion of the cylindrical main body portion It has a through hole with an inner diameter smaller than the diameter, and is almost even around the through hole. A plurality of bolt holes are provided at intervals, and an annular connecting portion connected to the cylindrical main body portion by passing the relay cylindrical portion of the cylindrical main body portion through the through hole. The pedestrian signal lamp is passed through the through hole of the annular connecting part and the relay cylinder part of the cylindrical main body part is passed through the plurality of bolt holes around the through hole. respectively through the fastening bolt, and is connected by pressing the foot portion of the tubular body portion at the periphery the lower surface of the through hole of the annular coupling section to the pedestrian signal lamp device by tightening screwed nut walking In the method for manufacturing a signal lamp mounting bracket for a person, the cylindrical main body is bent by approximately 90 degrees to form a curved shape, and the skirt is provided on the other end, and then the cylindrical main body is connected to the annular connecting portion. The one end side of the relay cylinder part inside By extruding, the arm metal coupling part having an inner diameter that is equal to or larger than the outer diameter of the relay cylinder part and substantially the same as the outer diameter of the arm metal is formed, and the arm metal coupling part is formed of the cylindrical main body part. When forming one end side of the relay cylinder part from the inside to be larger than the outer diameter of the relay cylinder part and having an inner diameter substantially equal to the outer diameter of the arm metal so that the arm metal is inserted, the direction of the arm metal The protrusion amount of the armrest side connecting portion on the outer peripheral side of the relay tube portion bent toward the direction of the signal lamp is made larger than the protrusion amount of the armrest side connecting portion on the inner periphery side of the relay tube portion. It is characterized by that.
Here, before the Kiudekin connecting portion, by providing the bolt hole fastening the fastening bolt passing through for coupling the arm-four positions or more, can be selected through the direction of its tightening fastening bolt 2 or more It is good to do so.

In the method for manufacturing a pedestrian signal lamp mounting bracket according to the present invention , the pedestrian signal lamp is such that the relay cylinder part of the cylindrical main body part is passed through the through hole of the annular connecting part and is substantially even around the through hole. By passing fastening bolts through a plurality of bolt holes 12b provided at intervals, and screwing and tightening nuts, the lower end of the peripheral edge of the through hole of the annular coupling portion is walked along the skirt portion of the cylindrical main body portion. Since it pushes and connects with the signal lamp for people, it becomes possible to pinch the skirt part of a cylindrical main part with almost equal power. Therefore, it is possible to effectively prevent the pedestrian signal lamp from rotating due to strong wind or the like.
Further, since the number of parts other than the tightening bolt and nut is reduced to two points of the cylindrical main body and the annular connecting portion, the weight of the metal fitting itself can be reduced and the mounting workability of the signal lamp is improved. be able to.
Further, since the protrusion amount on the inner peripheral surface side of the arm metal connection portion is smaller than the protrusion amount on the outer peripheral surface side of the arm metal connection portion, the connection portion on the inner peripheral side of the arm metal connection portion and the relay cylinder portion is reduced.

  Embodiments 1 and 2 of a pedestrian signal lamp mounting bracket 1 according to the present invention will be described below with reference to the drawings.

Embodiment 1. FIG.
As shown in FIGS. 1 and 2, the pedestrian signal lamp mounting bracket 1 according to the first embodiment is connected to a pair of arm brackets 3 and 3 extending in a horizontal direction at a predetermined interval from a support pole 2 such as a utility pole. At the same time, it is connected to the upper and lower parts of a pedestrian signal lamp (hereinafter sometimes abbreviated as a signal lamp as appropriate) 4 for attaching the pedestrian signal lamp 4 to the pole 2 such as a utility pole. As a component other than the tightening bolts 51 and 61 and the nuts 52 and 62, a cylindrical main body 11 and an annular connecting portion 12 are provided.

  As shown in FIGS. 3 to 9, the cylindrical main body portion 11 has an arm metal coupling portion 11 a that is coupled to the arm metal 3 on one end side, and the other end side is the pedestrian signal lamp device 4 side. The front end portion has a skirt portion 11b that spreads outward, and is bent toward the direction of the pedestrian signal lamp 4 from the direction parallel to the longitudinal direction of the arm bracket 3 between the arm metal coupling portion 11a and the skirt portion 11b. A curved relay cylinder portion 11c.

  As shown in FIG. 9, the arm metal coupling portion 11a pushes one end side of the relay cylinder portion 11c of the cylindrical main body portion 11 from the inside so that the arm metal 3 is inserted inside as shown in FIG. The inner diameter r1 of the gold connecting portion 11a is formed to be equal to or larger than the outer diameter r2 of the relay cylinder portion 11c and substantially the same as the outer diameter of the arm metal 3. Extrusion from the inside refers to plastic working from the inside to the outside, and includes a wide range of technical methods such as bulge forming (hydroforming) and general press working.

  Here, as shown in FIG. 10 (a), the armband connecting portion 11a is formed by bending the cylindrical main body portion 11 by approximately 90 degrees to form a curved shape, and providing the skirt portion 11b on the other end side. The cylindrical main body 11 is passed through the annular connecting portion 12 as shown in FIG. 10 (b), and then the one end side of the relay cylindrical portion 11c is pushed out from the inside as shown in FIG. 10 (c). As shown in FIG. 9, an arm metal coupling portion 11a having an inner diameter r1 which is equal to or larger than the outer diameter r2 of the relay cylinder portion 11c and substantially the same as the outer diameter of the arm metal 3 is formed. And after forming the arm metal coupling part 11a as mentioned above, four bolt holes 11a1 mentioned later are formed in the arm metal coupling part 11a.

  At that time, as shown in FIG. 9, the armband connecting portion 11 a is a relay that is bent from the direction parallel to the outer peripheral surface of the armmetal connecting portion 11 a and the longitudinal direction of the armmetal 3 toward the pedestrian signal lamp 4. In a state where the protruding amount d1 between the outer peripheral surface of the cylindrical portion 11c is larger than the protruding amount d2 between the inner peripheral surface of the armature connecting portion 11a and the inner peripheral surface of the relay cylindrical portion 11c, An inner diameter r1 of 11a is secured.

  Therefore, as shown in FIGS. 10A to 10C, after bending the relay cylinder part 11c, one end side of the cylindrical main body part 11 is expanded to the size of the outer diameter of the arm metal 3, thereby connecting the arm metal coupling part 11a. Since the protrusion amount d2 on the inner peripheral surface side of the arm metal connecting portion 11a is smaller than the protrusion amount d1 on the outer peripheral surface side of the arm metal connecting portion 11a, the arm metal connecting portion 11a and the relay cylinder portion 11c are provided. It is possible to suppress the occurrence of cracks and the like at the connecting portion on the inner peripheral side of the tube, and the cylindrical body portion 11 can be easily processed accordingly, and the pedestrian signal lamp 4 can be stably supported over a long period of time. A pedestrian signal lamp mounting bracket 1 can be provided.

  Further, as shown in FIG. 4 and the like, the arm metal connecting portion 11a is provided with four bolt holes 11a1 through which the tightening bolts 61 for connecting to the arm metal 3 are provided at intervals of 90 degrees. Two penetration directions of the bolt 61 can be selected in the horizontal direction and the vertical direction.

  Therefore, even when the direction of the bolt hole through which the fastening bolt 61 of the arm metal 3 is passed is changed easily and flexibly.

  As shown in FIG. 9, the annular connecting part 12 has an outer diameter r2 or more of the relay cylinder part 11c of the cylindrical main body part 11, and the outer diameters of the arm metal connecting part 11a and the skirt part 11b of the cylindrical main body part 11. The through hole 12a has an inner diameter smaller than r3, and the relay cylinder part 11c of the cylindrical main body part 11 is configured to pass through the through hole 12a.

  Therefore, the annular connecting portion 12 and the tubular main body portion 11 constituting the pedestrian signal lamp mounting bracket 1 of the first embodiment are provided with a tightening bolt 51 and a nut before being attached to the pedestrian signal lamp 4 or the brace 3. Since it is not separated even if it is not fastened with 52, it is easy to store and transport, and even during installation, the parts are not separated even without the fastening bolt 51 and nut 52, so it is easy to install at a high place. But work efficiency improves.

  In addition, the annular connecting portion 12 is provided with three bolt holes 12b for passing the fastening bolts 51 for attachment to the pedestrian signal lamp 4 at every 120 degrees at substantially equal intervals. However, the number and interval of the bolt holes 12b are merely examples, and the number corresponding to the number of connection holes and the interval of the pedestrian signal lamp device 4 is provided.

  Further, as shown in FIG. 9 and the like, the annular connecting portion 12 is formed in a U-shaped cross section and is provided with an inner annular convex portion 12c and an outer annular convex portion 12d, thereby reducing the weight of the annular connecting portion 12 itself. In consideration of the thickness of the bottom portion 11b of the cylindrical main body portion 11 and the fastening force to the bottom portion 11b, the height of the lower end portion (tip portion) of the inner annular convex portion 12c is set to the outer annular convex portion 12d. It is made higher than the height of the lower end part (tip part).

  It is also possible to pass the annular coupling part 12 through the relay cylinder part 11c after forming the arm metal coupling part 11a by pushing one end side of the relay cylinder part 11c from the inside. In this case, the annular connecting portion 12 is formed of a half ring (two or more may be used).

  Therefore, the pedestrian signal lamp mounting bracket 1 of the first embodiment includes the cylindrical main body portion 11 and the annular connecting portion 12, and is connected to the arm metal 3 via the arm metal connecting portion 11a of the cylindrical main body portion 11. On the other hand, the pedestrian signal lamp 4 passes through the through hole 12a of the annular connecting part 12 through the relay cylinder part 11c of the cylindrical main body part 11 and a plurality of bolt holes at substantially equal intervals around the through hole 12a. The fastening bolts 51 are passed through the respective bolts 12b, and the nuts 52 are screwed into the fastening bolts 51 from the back side of the outer side surface of the pedestrian signal lamp 4 to be tightened. Between the lower end portion of the annular convex portion 12c and the outer surface of the pedestrian signal lamp 4 (other members such as a washer and waterproof packing may be interposed between them if necessary). By sandwiching the skirt part 11b, the ring In connection portion 12 is pressed against the skirt portion 11b of the cylindrical main body portion 11 in the pedestrian signal lamp unit 4 connecting the tubular main body portion 11 in the pedestrian signal lamp unit 4. Note that, conversely, a configuration in which the fastening bolt 51 is passed from the inside of the pedestrian signal lamp 4 and the nut 52 is screwed from the annular connecting portion 12 side is naturally possible.

  Therefore, according to the pedestrian signal lamp mounting bracket 1 of Embodiment 1, the skirt portion 11b of the cylindrical main body portion 11 is sandwiched between the plurality of fastening bolts 51 and the nuts 52 fastened at substantially equal intervals with a substantially equal force. Therefore, it is possible to effectively prevent the pedestrian signal lamp 4 from rotating due to strong wind or the like, and to provide a structure in which the pedestrian signal lamp 4 is difficult to rotate.

  Further, unlike the conventional pedestrian signal lamp mounting bracket described above, the fastening bolts and nuts that fasten the protruding connecting portions of the arm bracket side bracket and the signal lamp side bracket are unnecessary, thus reducing the weight of the bracket itself. In addition, it is possible to improve the installation workability of the signal lamp.

  Further, four bolt holes 11a1 ′ through which the fastening bolts 61 for connecting to the arm metal 3 pass are provided in the arm metal connecting portion 11a ′ at intervals of 90 degrees, and the fastening bolts 61 of the arm metal 3 are passed therethrough. Even if the direction of the bolt hole is changed, it can be easily and flexibly handled.

  Therefore, according to the pedestrian signal lamp mounting bracket 1 of the second embodiment, like the pedestrian signal lamp mounting bracket 1 of the first embodiment, the inner annular convex portion 12c at the periphery of the through hole 12a of the annular coupling portion 12 is provided. In order to fix to the pedestrian signal lamp 4 by sandwiching the skirt part 11b of the cylindrical main body part 11 between the lower end part and the outer surface of the pedestrian signal lamp apparatus 4, the skirt part 11b of the cylindrical main body part 11 is fixed. It is possible to pinch with almost equal force, and can effectively prevent the pedestrian signal lamp 4 from rotating due to strong wind or the like than the conventional one, and provide a structure in which the pedestrian signal lamp 4 is difficult to rotate. In addition, since the number of fastening bolts and nuts to be used is reduced, the weight of the metal fitting itself can be reduced, and the mounting workability of the signal lamp can be improved.
