[Detailed description of the device]

[0001]

[Field of Industrial Application] The present invention relates to a tall pole for displaying carp streamers, national flags, and the like.

[0002]

2. Description of the Related Art A conventional pole is a single rod,
The work to build was difficult. Therefore, recently, one pole is divided into a plurality of poles, and at the place where the poles are built, the divided poles are assembled into one pole and then constructed.

[0003]

[Problems to be Solved by the Invention] However, even a conventional assembling-type pole is constructed by assembling it into one pole, so that it is a long pole when constructed. The length of the pole is 10 m or more, and since it is made of metal, it is considerably heavy. Therefore, if the place to build the pole is narrow, it is difficult to actually build it, and even if it can be built in a wide place, the weight of the whole pole is very heavy and it is dangerous to build the heavy pole vertically. there were. Especially when it was windy, it was very dangerous. And, the work required two or more manpower. Therefore, the present invention solves such a conventional problem,
It is a safe and easy way to build a pole, and it can be used in a narrow space so that one person can work on it.

[0004]

According to the present invention, the poles 5b, 5c, 5d, 5e, 5f and 5h having different diameters are slidably inserted into the ground so as to sandwich the pole 5a and the pole 5a. In the pole 5 which is composed of a pillar and the pole 5a is fixed to the pillar, a pulley 13 is attached to the tip.
The auxiliary pole 11 fixed with is fixed along the pole 5a, another pulley 15 is attached to one end of the rope 14 passed through the pulley 13, and the wire 17 and the safety belt 18 are attached to the hook 16 of the other pulley 15. The length of the safety belt 18 is adjusted to the length of the poles 5b, 5c, 5d, 5e, 5f by hanging one end. Of course, the number of columns may be one. further,
An inverted V-shaped notch 31 is provided at the lower end of each of the poles 5b, 5c, 5d, 5e, and 5f.
The pin holes 30 are provided in d, 5e, and 5f, and the pin holes 30 and V
The pin 40 can be inserted into the character-shaped notch 31.
The wire 17 and the safety belt 18 may be directly attached to the rope 14.

[0005]

Operation: First, the poles 5a are sandwiched so that the columns 1, 2
Drive into the ground, and the through holes 3, 4, 3a of the columns 1 and 2,
4a and the through holes 6, 6a of the pole 5a, bolts 7, 7a
Through the bolts, tighten the bolts, fit the fixing brackets 8 and tighten the bolts 9 to fix the poles 5a to the columns 1 and 2. Next,
An auxiliary pole 11 having a pulley 13 fixed at its tip is built along the pole 5a, and a wire 17 and a safety belt 18 are hung on a hook 16 of another pulley 15 attached to one end of a rope 14 passed through the pulley 13. , The wire 17 is hooked on the bolt 21 connecting and fixing the pole 5h and the pole 5f, and the other end of the safety belt 18 is hooked on the head of the bolt 9 of the fixing member 8. Next, pulling the other end of the rope 14 lifts the pole 5f and pulls the safety belt 18 until the pole 5f is pulled.
When f rises, the pin 40 penetrates the pin hole 30. Then, the pole 5f is slightly rotated, and when the pin 40 fits into the inverted V-shaped notch 31, the rope 14 is released. Next, the bolt holes 32, 33, 34, 3 of the poles 5e, 5f
Insert bolts 22 and 23 through 5, tighten with a nut, pin 40
Remove. Then, next, the pole 5e and the pole 5d are connected and fixed, the pole 5d and the pole 5c are connected and fixed, the pole 5c and the pole 5b are connected and fixed, and further, the pole 5b.
And the pole 5a are connected and fixed, the pole is assembled, and at the same time the pole is built up.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. First, as shown in FIG. 2, the pillars 1 and 2 driven into the ground so as to sandwich the pole 5a are penetrated respectively. The holes 3, 3a, 4, 4a are provided. A bolt 7 is passed through the through holes 3 and 4 and the through hole 6 provided in the pole 5a and bolted. Similarly, the through holes 3a and 4a and the through hole 6a of the pole 5a are bolted with the bolt 7a, and the fixing bracket 8 And then tighten the bolts 9 to fix the poles 5a to the columns 1 and 2. Next, as shown in FIG. 1, after the pole 5a is built up, the auxiliary pole 11 having the pulleys 13 of the two wheels fixed at the tip is built along the pole 5a and tied with the string 12 to be fixed. Another pulley 15 is attached to one end of the rope 14 passed through the pulley 13. Then, the wire 17 and the hole at one end of the safety belt 18 are hooked on the hanging tool 16 of another pulley 15, and the wire 17 is hooked on the bolt 21 of the bolts 20 and 21 connecting and fixing the pole 5h and the pole 5f in advance. The hole at the other end of the safety belt 18 is hooked on the head of the bolt 9 of the fixing fitting 8 shown in FIG.

Next, when the other end of the rope 14 shown in FIG. 1 is pulled, the pole 5f is lifted up and the position of the hole of the safety belt 18 is adjusted in advance to the length of the pole 5f. As shown in FIG. 5, when the pole 5f is lifted up near the lower end, it is pulled by the safety belt 18,
The rope 14 does not rise any further. When the pole 5f rises, the pin 40 is passed through the pin hole 30 and the pole 5f is slightly rotated, and when the pin 40 fits into the inverted V-shaped notch 31, the rope 14 is released. When the pin 40 is penetrated, the bolt hole 32 and the bolt hole 34 are aligned with each other. Therefore, the bolt 22 is penetrated into the bolt holes 32 and 34, and then the bolt 23 is penetrated into the bolt holes 33 and 35, and the nut is penetrated. Tighten and remove the pin 40. Since the safety belt 18 is provided, the pole 5f does not rise too much, but a mark 36 may be provided near the lower end of the pole 5f as a precaution, just in case.
Then, when the rope 14 is hung on the nut 23 and the rope 14 is pulled, the pole 5e is lifted and the lower end of the pole 5e is bolted. Then, the pole 5d, the pole 5c, the pole 5b, and the pole 5a are sequentially bolted to build the pole 5, the string 12 is unwound, and the sub pole 11 is removed. The length of the safety belt 18 is adapted to the length of the pole 5e, the pole 5d, the pole 5c, and the pole 5b. On the contrary, when removing the pole 5, the procedure of building up can be reversed.

[0008]

The peculiar effect of the present invention is that since the pole can be assembled and installed at the same time, the installation is very easy and safe. Moreover, it can be installed safely even in a small installation location. Furthermore, it can be installed by only one person. And it is very easy and safe to remove the pole. In addition, the present invention has a compact structure and can be supplied at a low cost because of its structure.
