Embodiments of the present invention will be described below with reference to the drawings. The present invention is not limited to the embodiments shown in the drawings.

Embodiment 1.
This embodiment will be described with reference to FIGS.
The pedestal 100 of this embodiment is for mounting the lighting fixture 200 on a pole 300 such as an electric pole or a pole or a wall surface 400.

The pedestal 100 includes a mounting portion 110 for mounting the lighting fixture 200, two reinforcing portions 120 respectively provided on both sides of the mounting portion 110, a connecting portion 130 connecting the two reinforcing portions 120, and a lighting unit. A lighting fixture fastener 140 for fixing the fixture 200 to the mounting portion 110 and a fall prevention device 150 for preventing the lighting fixture 200 from falling. The gantry 100 is formed by, for example, bending, pressing, or welding a metal plate having a thickness of 1 mm to 4 mm.

In addition, the mounting portion 110 is mounted with a trapezoidal mounting end portion 111 for mounting the pole 300 on one end side, a lighting fixture mounting hole 112 for mounting the lighting fixture 200, and a fall prevention tool 140. A fall prevention tool mounting hole 113 is formed.

The mounting end 111 is a notched end 111 a of the trapezoidal shape, the upper side of which is in contact with the pole 300.

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

The upright portion 121 has two oblong holes 121a having a rectangular shape, an elliptical shape, or an oval shape formed at one end side to which the pole 300 is attached. The elongated hole 121a is for fastening the pedestal 100 to the pole 300 by the band 500.

The standing portion 121 has a substantially right-angled triangular shape, and when the portion corresponding to the bottom side 121b contacts the mounting portion 110 and the portion corresponding to the height 121c contacts the pole 300, the portion corresponding to the hypotenuse 121d is , Has a curved shape. This curve draws a parabola that is recessed toward the base 121b and the height 121c. In this way, by making the oblique side 121d 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 standing portion 121 is reduced so that the oblique side 121d has a corner, stress may concentrate at this corner and cracks may occur, but since it is formed in a curved line, stress does not concentrate. Therefore, even if the oblique side 121d is made straight, the strength of the standing portion 121 does not decrease, and the strength can be maintained almost the same.

The wall mounting portion 122 is formed so as to project toward the outside of the gantry 100, and has a fixing hole 122a into which a wall surface fastener 410 such as a screw or a bolt for mounting on the wall surface 400 is inserted.

A flat portion 131 is formed on the connecting portion 130, and the connecting portion 130 is attached to the reinforcing portion 120 such that the flat portion 131 is substantially parallel to the attachment portion 110. The edge 131a 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 notched end 111a of the trapezoidal shape when the mounting portion 110 is directly viewed. Accordingly, when the pedestal 100 is attached to the pole 300, one end of the attachment portion 110 and one end of the standing portion 121 come into contact with the edge of the connecting portion 130, so that the pedestal 100 is stable with respect to the pole 300. It can be attached in a loose state (a state in which there is little rattling or inclination with respect to the pole 300).

The lighting fixture fastener 140 is fastened to the nut 141 welded, welded, or bonded to the mounting portion 110 so that the screw hole communicates with the lighting fixture mounting hole 112, and is fastened to the nut 141 to fix the lighting fixture 200. The bolt 142.

The fall prevention tool 150 is inserted into the wire 151 wound around the lighting fixture 200, the fall prevention fitting 152 to which the wire 151 is attached, and the fall prevention fitting attachment hole 113, and the fall prevention fitting 152 is attached to the attachment portion 110. It has a fall prevention fastener 153 to be fastened. The fall prevention tool 150 is for preventing the lighting fixture 200 from dropping to the ground or the like if the lighting fixture fastener 140 that fixes the lighting fixture 200 to the mounting portion 110 comes off.

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

Next, a method of attaching the pedestal 100 for attaching the lighting fixture 200 to the pole 300 will be described.
First, the pole 300 is brought into contact with one end side (mounting end 111) of the mounting portion 110, which is the end portion of the gantry 100, one end side (height 121c) of the reinforcing portion 120, and the end side 131c of the connecting portion 130. Contact. In this state, the band 500 is wound around the pole 300 so that the elongated holes 121a of the two reinforcing portions 120 communicate with each other. Since two long holes 121a are provided in each of the reinforcing portions 120, the pedestal 100 is fastened to the pole 300 by tightening two bands 500.

Next, the lighting fixture 200 is placed on the mounting portion 110 of the pedestal 100, the bolt 142 is inserted into the lighting fixture mounting hole 112, and is fastened to the nut 141, whereby the lighting fixture 200 is installed on the pedestal 100.

At this time, the weight of the lighting fixture 200 attached to the attachment portion 110 is applied to the attachment portion 110, and the attachment portion 110 tends to deform. However, since the mounting portion 110 is reinforced by the reinforcing portion 120, deformation of the mounting portion 110 is suppressed. Note that the reinforcing portion 120 is stressed in order to suppress the deformation of the mounting portion 110, and the oblique side 121d of the reinforcing portion 120 is also weighted. However, as described above, since the oblique side 121d is formed by a curved line, The stress due to the load is dispersed. Therefore, it is possible to reduce the weight of the reinforcing portion 120 and suppress the deformation of the mounting portion 110.

Further, when the reinforcing portion 120 is pressed against the pole 300 due to the weight of the lighting fixture 200, a force is applied in a direction in which the reinforcing portions 120 spread, but by connecting the two reinforcing portions 120 with the connecting portion 130, It is possible to prevent the two reinforcing portions 120 from expanding.

Finally, a method of mounting the pedestal 100 for mounting the lighting fixture 200 on the wall surface 400 will be described.

A wall mount 410 is provided on the wall 400. The wall surface mount 410 includes, for example, an anchor bolt 411 that is mounted on 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 mounting portion 122 makes 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 pedestal 100 is mounted on the wall surface 400.
Next, the lighting fixture 200 is installed on the pedestal 100 fixed to the wall surface 400. The method and effect of attaching the luminaire 200 to the pedestal 100 are the same as when the pedestal 100 is attached to the pole 200, and therefore the description thereof is omitted. To do.
