Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a tall pole for displaying a streamer, a national flag, etc.

[0002]

[Prior art]

 A conventional pole is a single rod, and it was difficult to carry and build it. Therefore, recently, one pole is divided into multiple poles, and at the place where the pole is built, the divided poles are assembled into one pole and then constructed.

[0003]

[Issues to be solved by the device]

 However, even a conventional assembly-type pole is built after it is assembled into one pole, so when it is built, it becomes a long pole. The length of the pole is more than 10m, and since it is made of metal, it becomes a considerable weight. Therefore, if the place to build the pole is small, 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. Met. Especially when it was windy, it was very dangerous. Then, the work required two or more manpower. Therefore, the present invention solves such a conventional problem, allows a pole to be built safely and easily, enables even a narrow space, and enables one person to work.

[0004]

[Means for Solving the Problems]

 The present invention comprises a pole 5a having slidably inserted divided poles 5b, 5c, 5d, 5e, 5f, and 5h having different diameters, and a pillar driven into the ground so as to sandwich the pole 5a. In the pole 5 fixed to the above, a sub-pole 11 having a pulley 13 fixed at the tip is built along the pole 5a, and another pulley 15 is attached to one end of the rope 14 passed through the pulley 13 and another pulley 15 is attached. The wire 17 and one end of the safety belt 18 are hung on the hanging tool 16 of 15, and the length of the safety belt 18 is adjusted to the length of the poles 5b, 5c, 5d, 5e, 5f. Of course, the number of columns may be one. Further, an inverted V-shaped notch 31 is provided at the lower ends of the poles 5b, 5c, 5d, 5e, and 5f, and pin holes 30 are provided in the poles 5a, 5b, 5c, 5d, 5e, and 5f. The pin 40 can be inserted into the hole 30 and the inverted V-shaped notch 31. The wire 17 and the safety belt 18 may be directly attached to the rope 14.

[0005]

[Action]

 First, the pillars 1 and 2 are driven into the ground so as to sandwich the pole 5a, and the bolts 7 and 7a are passed through the through holes 3, 4, 3a and 4a of the pillars 1 and 2 and the through holes 6 and 6a of the pole 5a. Tighten, fit the fixing metal fitting 8, and tighten with the bolt 9 to fix the pole 5a to the columns 1 and 2. Next, the auxiliary pole 11 having the pulley 13 fixed to the tip is built along the pole 5a, and the wire 17 and the safety belt 18 are attached to the hook 16 of another pulley 15 attached to one end of the rope 14 passed through the pulley 13. The wire 17 is hung on the bolt 21 for connecting and fixing the pole 5h and the pole 5f, and the other end of the safety belt 18 is hung on the head of the bolt 9 of the fixing fitting 8. Next, when the other end of the rope 14 is pulled, the pole 5f is lifted, and when the pole 5f rises until the safety belt 18 is pulled, the pin 40 is penetrated into the pin hole 30. Then, the pole 5f is slightly rotated, and when the pin 40 is fitted into the inverted V-shaped notch 31, the rope 14 is released. Next, the bolts 22 and 23 are passed through the bolt holes 32, 33, 34 and 35 of the poles 5e and 5f, tightened with nuts, and the pin 40 is removed. 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, Assemble the pole and build it at the same time.

【Example】

 An embodiment of the present invention will be described with reference to the drawings. First, as shown in FIG. 2, through-holes 3, 2 are respectively formed in columns 1, 2 driven into the ground so as to sandwich a pole 5a. 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 fastened with bolts. Similarly, the through holes 3a and 4a and the through hole 6a of the pole 5a are fastened with bolts 7a, and the fixing bracket 8 And 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 the other pulley 15, and the wire 17 is hooked on the bolt 21 of the bolts 20 and 21 in which the pole 5h and the pole 5f are fixed in advance. Hook the hole at the other end of the safety belt 18 on the head of the bolt 9 of the fixing metal 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 and 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. Tighten with a nut and remove pin 40. Since the safety belt 18 is provided, the pole 5f will not rise too much, but as a precaution, a mark 36 may be provided near the lower end of the pole 5f. Then, when the rope 14 is hooked 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 bolted in order to erect the pole 5, the string 12 is unwound, and the auxiliary 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.
