Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a street pole on which illumination lights, signal lights, and other street signs can be installed in desired combinations according to installation conditions.

(Prior Art) In conventional street poles, a metal belt is simply tightened to the mounting position of a columnar pole, and the end of the mounting arm is bolted to the outer bent edge of one end of the metal belt.
It was constructed to be integrated with welding.

(Problem to be solved by the invention) However, since metal belts are configured to be wrapped directly around the middle part of a columnar pole, even a slight tightening defect can easily cause the fixation to become unstable. When trying to install a The aesthetic appearance of the streets was to become even worse.

The present invention eliminates these conventional drawbacks, and improves the stability of fixation by allowing the pole to be mounted almost in line with the outer diameter of the pole, and also allows the mounting arm to be placed in two or more directions from the same position. Furthermore, it is an object of the present invention to provide a street pole that can be changed and replaced, and at the same time exhibits an excellent aesthetic appearance.

(Means for solving the problem) In order to achieve the above object, the present invention makes the mounting arm installation part of the pole a small diameter part, and the length of the small diameter part is at least twice the vertical width of the tightening belt. forming a substantially U-shaped tightening belt around the small diameter portion,
A mounting part is provided with a structure in which a mounting tool having a mounting arm fixing seat with a vertical length approximately twice to twice or more than the vertical width of the tightening belt is sandwiched on the open end side of the tightening belt, It is characterized in that the mounting arm is fixed to the mounting arm fixing seat to form a street pole.

(Function) The tightening belt is wrapped around the small diameter part so that the outer diameter approximately matches the outside diameter of the pole. The mounting arm can be extended in the direction.

(Example) Figure 1 shows an example of a street pole according to the present invention, in which a roadway lighting light is installed at the upper end, a roadway signal light, etc. is installed at the middle position, and a sidewalk is installed at the 180° opposite side of the same position. Lighting lights are installed on each side, and sidewalk signal lights are installed at the bottom.

Also, Figure 2 shows another example,
Roadway illumination lights, signal lights, etc. on both the left and right sides are installed at the top and middle positions. The installation of the mounting arm for supporting lights and other indicators can be arranged in a wide variety of other ways, and this variety will become clear in the following description.

FIGS. 3 and 4 show the configuration of the mounting portion of the mounting arm of the street pole illustrated above.

Reference numeral 1 is a pillar-shaped pole, and although the cross-sectional shape may be any shape, it is shown as a hollow circle in the figure, and the small-diameter part 1 is used to attach lighting lights, signal lights, and other display objects.
It is becoming known as a. The small diameter portion 1a is formed by fitting the small diameter pole into the main body of the pole 1 in a connected manner and welding it together. For example, in the case of the upper end of the pole 1 shown in FIG. 1, the length is twice as long as the vertical width of the tightening belt 2. In the case of the middle part and the lower part, the length is set to approximately multiple times the length of the tightening belt 2, such as four times the length.

The tightening belt 2 has a tightening end portion 2 extending in parallel from a curved portion 2a that is wrapped around the small diameter portion 1a of the pole 1 and whose outer surface is approximately flush with the outer peripheral surface of the pole 1.
It is formed into a substantially U-shape with a b.

Inside the tightening end 2b, there is a small diameter portion 1 of the pole.
A thick plate-shaped connecting member 3 having an inner end that can come into contact with a is brought into contact with a screw hole 3a formed in advance in the member.
In contrast, a bolt 4 is screwed through a bolt insertion hole 2c formed in advance in the tightening end 2b to connect the two, and bolts 5, 5 are inserted through both the tightening end 2b and the connecting member 3. Insertion hole 2
A plurality of each of d and 3d (two of each in the figure) are formed.

Note that the tightening end portion 2b and the connecting member 3 may be integrated by welding.

The fixture 6 has a mounting arm fixing seat 6a having a width approximately equal to the diameter of the pole 1 and a vertical length approximately multiple times (approximately twice in the figure) the vertical width of the tightening belt 2. At the center of the upper half of the back side, there is a connecting member 3, which is interposed with a slight gap between the connecting members 3, 3 when the tightening belt 2 is tightened to the small diameter part 1a, and at the same time, the tip part is in contact with the small diameter part 1a. A connecting protrusion 6b of a possible shape is provided protrudingly, and a wire insertion hole 6c is formed in the upper center of the mounting arm fixing seat 6a, and a plurality of screw holes 6d for fixing the attaching arm are formed in the other part. Screw holes 6e, 6e into which the bolts 5, 5 are screwed are formed from both sides.

Reference numeral 8 denotes the base of the mounting arm 7 in any form, and has an end surface 8a that comes into contact with the surface of the mounting arm fixing seat 6a, and a wire insertion hole (not shown) and a screw hole 6d are screwed into the end surface 8a. A bolt insertion hole (not shown) is formed for tightening the bolt, and a space 8b for bolt tightening is formed on the outside of the end surface 8a. The contacting edge piece 8c is formed in an overhanging manner.

The tightening belt 2 is wound around the small diameter portion 1a of the pole, and the connecting member 3 is placed inside both tightening ends 2b.
3 are connected with bolts 4, 4, and then the connecting protrusion 6b is inserted between both connecting members 3, 3, and the bolt 5 is tightened from the outside of the tightening end 2b to fix the whole, thereby forming a mounting part. As a result, the curved portion 2a
tightens the small diameter part 1a, and the inner end of the connecting member 3 and the inner end of the coupling protrusion 6b firmly abut on the small diameter part 1a, and at the same time, these are supported by the step between the pole 1 and the small diameter part 1a. The entire mounting part is stabilized and firmly fixed.

The mounting arm 7 is connected and fixed to the mounting arm fixing seat 6a,
The mounting arm 7 is equipped with illumination lights, signal lights, guidance displays, and other arbitrary displays.

The aspect of the mounting portion having the above configuration will be further explained.

First, in the example shown in FIG. 5, that is, the attachment part shown in the middle of the pole in FIG. The upper end of the tightening belt 2 is attached to the tightening end 2b.
The mounting arm fixing seat 6a is installed so that half of the mounting arm fixing seat 6a extends downward, and the second-stage tightening belt 2 is oriented left and right opposite to the above, and the mounting arm fixing seat 6a is The half part is installed so as to extend to the same position as the upper tightening belt 2, and the third stage has a two-split cylindrical body with the same width as the tightening belt 2 and the same diameter as the curved part 2a. The fourth stage is placed vertically symmetrically with the first stage.

According to this, since the first and fourth stage mounting arm fixing seats 6a and 6a are arranged vertically and continuously on the right side, a large mounting arm that straddles the entire surface of both fixing seats is installed. The bases 8 of 7 can be connected and fixed,
On the left side, a small mounting arm 7 can be connected and fixed to the upper mounting arm fixing seat 6a.

Figure 6 is a diagram of the mounting part around which the four tightening belts 2 shown in the middle part of the pole in Figure 2 are wrapped, and is vertically symmetrical to the upper two stages in Figure 5 above. It is composed of two lower stages arranged in the lower part. According to this, since the mounting arm fixing seats 6a are arranged vertically and continuously on both the left and right sides, it is possible to connect and fix the large mounting arms 7 on both the left and right sides.

FIG. 7 is a diagram of the attachment part shown at the bottom of the pole in FIG.
The upper and lower stages are vertically symmetrically arranged, and mounting arm fixing seats 6a are continuously arranged on one side, and the middle two stages have two mounting arm fixing seats 6a having the same diameter as the curved part 2a of the tightening belt. A split cylindrical body is wrapped around it. According to this, the large mounting arm 7 can be connected and fixed only to one side.

FIG. 8 shows yet another installation example, in which the mounting part is installed in the small diameter part 1a for 6 stages of the tightening belt, and 1, 2
The tiers are arranged in the same way as the 1st and 2nd tiers in Figure 5, and 3
The 3rd tier is arranged in the same way as the 1st tier, and the 6th tier is arranged in the same way as the 1st tier.
They are disposed vertically symmetrically with the tiers, and a split cylindrical body having the same diameter as the curved portion 2a of the tightening belt is wound around the fourth and fifth tiers. According to this, since three mounting arm fixing seats 6a are consecutively arranged on the right side, a larger mounting arm 7 than the above can be connected and fixed, and on the left side, a small mounting arm 7a can be connected and fixed. 7 can be connected and fixed.

In addition to the above, many other types of mounting portions can be selected. For example, the number of stages of the tightening belt 2 can be set arbitrarily, and the direction of the tightening belt 2, that is, the extending direction of the mounting arm 7, can be variably installed at an arbitrary angle, so that it can be moved in a desired direction such as front and rear, left and right, or diagonally. The mounting arms can be combined and installed in the following directions.
