JPH10280347A - External pipe of column for car stopper fence - Google Patents

Abstract

PROBLEM TO BE SOLVED: To use this external pipe of the fence column for a car stopper as both embedding type and detachable type, by dividing the external pipe to a plurality of vertical stages and making the length of fence column adjustable and connecting them to each other. SOLUTION: An external pipe is divided at the middle part to upper and lower pipes 3, 4 and the upper and lower flanges 31, 41 are integrally formed at the respective divided ends. A protrusion and a recession 42, 32 fitted to each other are formed in these upper and lower flanges 31, 41. When the external pipe is used as an embedding type, the protrusion and the recession are fitted mutually and superposed and fixed with screws 5 and nuts 6 to form a connection part 7 and join these upper and lower external pipes 3, 4.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outer pipe of a bollard post, and more particularly to an outer pipe of a bollard post that is strong in strength and can be used in both buried and detachable types.

[0002]

2. Description of the Related Art Conventionally, a buried fence post for storing the entire length of a pole in an outer pipe when not in use, and a detachable fence for extracting a pole from the outer pipe when not in use and storing the pole in another place when not in use. There are pillars. Because the buried fence post stores the entire length of the pole in the outer pipe when not in use, the outer pipe is formed longer than the full length of the pole, and the removable fence post pulls the pole out of the outer pipe when not in use The outer pipe was formed shorter than the pole, and each outer pipe had a different length. For this reason, outer pipes were separately made for buried and removable fence posts.

[0003]

The outer pipe is
Since production with synthetic resin using a molding die is preferable,
In the case of a conventional outer pipe of a bollard post, two types of molding dies are required for a pole having the same diameter, a buried type and a detachable type, and there is a problem that the die manufacturing cost is high.

[0004] In view of this problem, the invention according to claim 1 divides the outer pipe of the bollard fence post into a plurality of upper and lower stages, joins the fence post so that the length thereof can be adjusted, and installs or dismounts the fence post. An object of the present invention is to provide an outer pipe of a bollard fence post that can be used for any of the fence posts.

[0005]

According to a first aspect of the present invention, there is provided a car stop fence post having an outer pipe for accommodating a pole, the outer pipe being separated into a plurality of stages. Upper and lower flange portions are provided integrally at the lower end of the separated upper pipe and the upper end of the lower pipe, respectively, and the upper and lower flange portions can be joined.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view of an outer pipe of a brace post according to the present invention.

FIG. 1 is a partial cross-sectional side view of the buried fence post of the present invention, FIG. 2 is a plan view of FIG. 1, and FIG.
FIG. 2 is a bottom view of FIG. 1.

The outer pipe 1 shown in FIG. 1 is a buried fence post for storing the entire length of the pole 2 when not in use.
Is longer than the pole 2 and is formed in a round shape as shown in FIG. In the present embodiment, the outer pipe is round, but may be square.

The outer pipe 1 is preferably produced by injection molding a synthetic resin such as vinyl chloride into a closed mold, but it is preferably made of a cast (die-cast) product of aluminum, zinc alloy or the like. It is not limited to a synthetic resin.

At this time, the molding die is manufactured so that the outer pipe 1 is divided into two parts at the upper and lower middle portions, and the upper pipe 3 having upper and lower flange portions 31 and 41 at the divided ends with the die.
And the lower pipe 4 are formed to form concave and convex portions 32 and 42 which are fitted to the contact surfaces of the flange portions 31 and 41, respectively. This uneven portion is not always necessary.

[0011] Even if the pole guide 8 is integrated into the upper pipe 3 as a flange at the upper end, a separately prepared pole guide (not shown) is inserted into the upper end of the upper pipe 3 and a fixing plate (not shown). ), Both the upper pipe and the pole guide may be fixed.

When used as a buried fence post, FIG.
As shown in the figure, the upper and lower flange portions 31 and 41 of the upper pipe 3 and the lower pipe 4 are overlapped, the concave and convex portions 32 and 42 are fitted together, and the upper and lower pipes 3 and 4 are joined with the screw 5 and the nut 6. And

The total length of the upper pipe 3 and the lower pipe 4 is
It becomes longer than the length of the pole 2 and can be used as a buried fence post.

[0014] The connecting portion 7 is provided at a position other than the one portion of the intermediate portion.
It can be provided at a plurality of locations in the vertical direction of the outer pipe 1,
By providing the connecting portion 7, the strength of the outer pipe 1 can be increased.

When used as a removable fence post, the upper and lower flange portions 31 and 41 of the connecting portion 7 are connected to the screw 5 and the nut 6
And only the upper pipe 3 of the outer pipe 1 is used.

The outer pipe 1 is provided with reinforcing ribs 9 to reinforce the outer pipe 1.

[0017]

According to the first aspect of the present invention, since the outer pipe can be separated into a plurality of upper and lower stages and can be joined freely, if the outer pipe is joined longer than the length of the pole, the buried fence post can be used. It can be used as a detachable fence post if separated shortly. Therefore, it is not necessary to use two types of molding dies for the buried type and the removable type fence post, and there is an effect that the die manufacturing cost is reduced.

According to the present invention, since the outer pipe is divided into a plurality of upper and lower stages and molded, the molding die can be reduced in size.
Die manufacturing costs are significantly lower.

Further, by providing the connecting portion, the strength of the outer pipe can be increased.
