A lighting fixture 4 is mounted, and the upper pole 3 is rotatably connected to the top of the lower pole 2, that is, a portion closer to the lower end side than the intermediate portion of the upper pole 2, and the upper pole 3 is connected to the lower pole 2. On the other hand, the fixing means 5 for fixing / releasing the standing position is set to the upper pole 3
Is provided at the lower end of the upper pole 3, and the upper pole 3 is turned over on the upper pole 3 around the connection point with the lower pole 2,
An operation bar 6 for performing a return operation is detachably provided. The lower pole 2 is a hollow rectangular member having a rectangular cross section, and is fixed vertically on a road surface or the like. The upper pole 3 also uses a hollow rectangular section member.
The lighting fixture 4 incorporates a well-known lighting lamp. Note that, in addition to the lighting fixture 4, a translucent plastic outer box to which various signs, advertising characters, and the like are attached may be provided.

Next, FIG. 3 is an enlarged view of a connection structure between the lower pole 2 and the upper pole 3 and a fixing means 5 for fixing / releasing the upper pole 3 to a standing position with respect to the lower pole 2. A diagram is shown and will be described below. The upper pole 3 and the lower pole 2 are attached to a mounting auxiliary fitting 8 provided so as to be clamped from the outside of the upper pole 3 at a position closer to a lower end side than an intermediate portion of the upper pole 3, and a bolt member 7.
Through the upper pole 3 via the retaining nut 9,
It is rotatable by inserting it through a mounting member 11 on the top end side of the lower pole 2 via a spacer member 10, attaching a retaining nut 12 to the bolt member 7, and screwing a tightening nut 13 to the bolt member 7. Are connected. On the other hand, the fixing means 5 includes an attachment frame 14 provided at the lower end of the upper pole 3 and an L frame attached to the lower pole 2.
The upper pole 3 is fixed to the lower pole 2 by screwing the metal fitting 15 into a nut 17 in the mounting frame 14 with a fixing bolt 16 having a threaded tip. The fixing means 5 is provided at the lower end of the upper pole 3.
The inspection workers' hands on the ground
Has arrived.

[0008] An operation bar 6 for rotating and falling and returning the upper stage pole 3 is provided on the upper stage pole 3 with a bolt member 7 serving as a connecting shaft between the upper stage pole 3 and the lower stage pole 2.
The upper pole 3 and the lower pole 2 are detachably mounted in the axial direction so that they can be operated only at the time of work by a clamp means 18 provided in the vicinity and near the lower end of the upper pole 3.
