  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, this invention is not limited by the form of drawing shown below.

Embodiment 1 FIG.
This embodiment will be described with reference to FIGS.
The gantry 100 of this embodiment is for attaching the luminaire 200 to a pole 300 or a wall surface 400 such as a utility pole or a column.

  The gantry 100 includes a mounting portion 110 for installing the lighting fixture 200, two reinforcing portions 120 provided on both sides of the mounting portion 110, a connecting portion 130 that connects the two reinforcing portions 120 to each other, and an illumination. It has the lighting fixture fastener 140 which fixes the fixture 200 to the attaching part 110, and the fall prevention tool 150 for preventing that the lighting fixture 200 falls. The gantry 100 is formed by bending, pressing, welding, or the like, for example, a metal plate having a thickness of 1 mm to 4 mm.

  Further, the mounting portion 110 is mounted with a mounting end portion 111 cut into a trapezoidal shape so that the pole 300 can be mounted on one end side, a lighting fixture mounting hole 112 for mounting the lighting fixture 200, and a fall prevention device 140. A fall prevention tool mounting hole 113 is formed.

  The attachment end 111 is a cut-out end 111 a in which the upper side portion of the cut trapezoidal shape comes into contact with the pole 300.

  The reinforcing portion 120 has a standing portion 121 that is erected from the mounting portion 110 in a substantially vertical direction, and a wall mounting portion 122 that is formed on one end side of the standing portion 121 to which the pole 300 is attached. .

  In the standing portion 121, two rectangular, elliptical, or oval long holes 121a are formed on one end side to which the pole 300 is attached. The elongated hole 121 a is for fastening the gantry 100 to the pole 300 by the band 500.

  The upright portion 121 has a substantially right triangle shape, and when the portion corresponding to the base 121b is in contact with the mounting portion 110 and the portion corresponding to the height 121c is in contact with the pole 300, the portion corresponding to the hypotenuse 121d is It has a shape that draws a curve. This curve depicts a parabola that is recessed toward the base 121b and height 121c. Thus, by making the hypotenuse 121d into a curve, the area (volume) of the standing portion 121 can be reduced, and the weight can be reduced. Further, if the area of the upright portion 121 is reduced so as to have a corner portion on the hypotenuse 121d, stress may concentrate on the corner portion and cracks may occur. However, since the curved portion is formed, the stress is not concentrated. Therefore, the strength of the standing portion 121 does not decrease even when compared with the case where the hypotenuse 121d is a straight line, and substantially the same strength can be maintained.

  The wall attachment portion 122 is formed so as to protrude outward from the gantry 100, and a fixing hole 122a into which a wall surface fastener 410 such as a screw or a bolt for attaching to the wall surface 400 is inserted is formed.

  The connecting part 130 is formed with a flat part 131 and is attached to the reinforcing part 120 so that the flat part 131 is substantially parallel to the attaching part 110. The end side 131 a of the connecting portion 130 contacts the pole 300 when the gantry 100 is attached to the pole 300. That is, one side end portion (end side 131a) of the connecting portion 130 is arranged in the same straight line as the trapezoidal cutout end 111a when the attachment portion 110 is viewed from the front. Accordingly, when the gantry 100 is attached to the pole 300, the end of the connecting portion 130 comes into contact with one end of the attachment portion 110 and one end of the standing portion 121. It can be attached in a state where there is little backlash and inclination with respect to the pole 300.

  The luminaire fastener 140 is fastened to the nut 141 welded, welded or bonded to the attachment portion 110 so that the screw hole communicates with the luminaire attachment hole 112, and is fixed to the nut 141 to fix the luminaire 200. And a bolt 142.

  The fall prevention tool 150 is inserted into a wire 151 wound around the lighting fixture 200, a fall prevention mounting bracket 152 to which the wire 151 is mounted, and a fall prevention mounting hole 113, and the fall prevention mounting bracket 152 is attached to the mounting portion 110. And a fall prevention fastener 153 to be fastened. This fall prevention tool 150 is for preventing the lighting fixture 200 from falling onto the ground or the like when the lighting fixture fastener 140 fixing the lighting fixture 200 to the mounting portion 110 is removed.

  The fall prevention fastener 153 includes a nut 153a and a bolt 153b fastened to the nut 153a.

Next, a method for attaching the gantry 100 for attaching the luminaire 200 to the pole 300 will be described.
First, the pole 300 is brought into contact with one end side (attachment end portion 111) of the attachment portion 110, which is the end portion of the gantry 100, one end side (height 121 c) of the reinforcement portion 120, and the end side 131 c of the connecting portion 130. Make contact. In this state, the band 500 is wound around the pole 300 so as to communicate the long holes 121a of the two reinforcing portions 120. Since there are two long holes 121 a in the reinforcing portion 120, the gantry 100 is fastened to the pole 300 by tightening the two bands 500.

  Next, the lighting fixture 200 is placed on the mounting portion 110 of the gantry 100, the bolt 142 is inserted into the lighting fixture mounting hole 112, and fastened to the nut 141, thereby installing the luminaire 200 on the gantry 100.

  At this time, the weight of the lighting fixture 200 attached to the attachment part 110 is applied to the attachment part 110, and the attachment part 110 tends to be deformed. However, since the attachment portion 110 is reinforced by the reinforcement portion 120, deformation of the attachment portion 110 is suppressed. The reinforcing portion 120 is stressed to suppress the deformation of the mounting portion 110, and the hypotenuse 121d of the reinforcing portion 120 is also weighted. However, as described above, the hypotenuse 121d is formed with a curve. The stress due to the load is distributed. Therefore, it is possible to reduce the weight of the reinforcing portion 120 and to suppress deformation of the mounting portion 110.

  Further, when the reinforcing part 120 is pressed against the pole 300 due to the load of the lighting fixture 200, a force is applied in the direction in which the reinforcing parts 120 spread, but by connecting the two reinforcing parts 120 by the connecting part 130, It is possible to suppress the two reinforcing portions 120 from spreading.

  Finally, a method of attaching the gantry 100 for attaching the lighting fixture 200 to the wall surface 400 will be described.

A wall surface fixture 410 is provided on the wall surface 400. The wall surface fixture 410 includes, for example, an anchor bolt 411 that is attached to the wall surface 400 in advance and a nut 412 that is screwed to the anchor bolt 411.
First, the nut 412 attached to the anchor bolt 411 is removed, and the anchor bolt 411 is inserted into the fixing hole 122a. As a result, the wall surface attachment portion 122 comes into surface contact with the wall surface 400.
Next, the nut 412 removed from the anchor bolt 411 is retightened to the anchor bolt 411, the wall surface mounting portion 122 is sandwiched between the wall surface 400 and the nut 412, and the mount 100 is attached to the wall surface 400.
Next, the luminaire 200 is installed on the gantry 100 fixed to the wall surface 400, but the method and effect of attaching the luminaire 200 to the gantry 100 are the same as those when the gantry 100 is attached to the pole 200, and thus the description thereof is omitted. To do.
