Description

[Detailed Description of the Invention] This invention relates to a pole interlocking support device that facilitates the burying of relatively lightweight poles such as traffic sign poles and outdoor light poles.

Conventionally, when installing poles upright in the ground, it is necessary to dig a hole as deep as the pole's embedding length, which is time-consuming and especially difficult to install on narrow roads or bottom gardens where excavators such as drill scrapers cannot enter. The problem was that it had to be dug by hand, which required a considerable amount of labor.

The purpose of this invention is to address the problems mentioned above.

That is, this invention uses a plurality of conical or pyramidal cylinders, and slidably inserts a plurality of cylinders, such as a middle cylinder and a lower cylinder, each having a smaller diameter into an upper cylinder with a larger diameter. When each cylindrical body is successively extruded and joined and extended, both adjacent cylindrical bodies are prevented from coming out by the overlapping margin at the ends, and a radial vane is removably attached to the outer peripheral surface of the upper cylindrical body, and the tip of the lower cylindrical body is At the same time as fixing a blind board, make the tip of the pole protrude from this blind board, drive the lower cylinder into the soil first, extend it in a joint style, and insert the lower end of the pole into this joint type cylinder. This is a leg-type support device for poles that is inserted and fixed with a coagulant or the like.

Hereinafter, embodiments of this invention will be described based on the accompanying drawings. As shown in FIGS. 1 and 2, the pole joint support device of this invention has a conical middle tube that gradually becomes smaller in diameter into a conical upper tube 1 with a larger diameter that expands upward. The body 2 and the conical lower cylinder 3 are slidably inserted, and when each cylinder is pushed out and stretched one after another and added, the adjacent cylinders come into close contact with each other at the overlap margin 4 (see Figure 3) at the ends, preventing them from coming out. state, and a pair of rectangular blades 5 are attached to the outer peripheral surface of the upper cylindrical body 1 with screws 6.
A blind plate 7 is fixed to the tip of the lower cylindrical body 3 and serves as a stopper during driving, and a tip 8 is protruded from the blind plate 7.

In addition to the above-mentioned combination of three cylinders, the upper cylinder 1, the middle cylinder 2, and the lower cylinder 3, the interlocking leg type support device can also combine two cylinders or four or more cylinders depending on the application. You can also combine them. The blades 5 are useful for improving stability when buried in the soil, but can be removed if the pole is short.

The lower cylindrical body 3 is formed so that the size of the upper surface of the blind plate 7 is substantially the same as the tip end surface of the inserted pole 9 (see FIG. 3).

FIG. 4 is a perspective view showing another embodiment of this invention. This pole's interlocking support device is a combination of an upper cylinder 1, a middle cylinder 2, and a lower cylinder 3 in the shape of a square pyramid, and when extended in an interlocking manner, each cylinder is attached to the cylinder core. It has excellent stability as it does not move around the axis. Therefore, the blades 5 can be omitted from the upper cylindrical body 1.

The pole interlocking support device according to this invention has the above-described structure. When using this device, as shown in FIG. , bury the shortened support device a little here to stabilize it, apply the driving tool to the blind plate 7 of the lower cylindrical body 3, and drive it almost vertically into the soil, as shown in Figure 3. As shown, the lower cylindrical body 3
As time goes on, the middle cylindrical body 2, which is locked at the overlapping margin 4, also penetrates into the soil, and the entire body is extended into a jointed state, and the casting is completed.
The lower end of the pole 9 is inserted into this cylindrical body, and while it is supported in an upright state by coming into contact with the blind plate 8, mortar 11 is filled and solidified, and the recess 10 is buried and the ground is leveled.

As described above, the pole joint support device of this invention has many advantages as listed below.

(1) If multiple cylinders are stacked in a shortened state, the bulk will be reduced and it will be advantageous for transportation and storage.

(2) It is a driven type, which allows the cylindrical body to be in close contact with the soil, resulting in a more solid buried condition than the conventional buried type, and the time and effort of digging deep holes can be omitted, making it easier to bury. can be done easily and quickly.

(3) Depending on the purpose, attaching blades to the cylindrical body,
Stability can be increased as appropriate by making each cylinder body.
