Description

[Detailed Description of the Invention] This invention relates to a spacer for stably installing a snow pole that is planted on the shoulder of a road in snowy areas to indicate its position.

In snowy areas, it becomes difficult to distinguish the shoulder of the road when the snow is falling, and accidents such as snow removal vehicles veering off the shoulder and falling are common.

For this reason, in these regions, poles called red and white painted in red and white are erected on the shoulder of the road in winter, and even when it snows, the top of the pole sticks out above the snow, making it easy to identify the shoulder of the road. That's what I do.

In the winter, these snow poles are inserted into a cylinder buried on the shoulder of the road with their lower ends inserted into an upright position, and from spring to autumn they are removed from the cylinder and the cylinder is covered with a lid.

Such snow poles have traditionally been made of composite or resin and have a relatively large diameter, but in recent years, smaller diameter snow poles have been made of aluminum or steel pipes.

However, when such a small-diameter snow pole is inserted into a cylinder installed to hold a conventional large-diameter snow pole,
The snow pole is shaking and tilting, making it impossible to set it up stably and reliably.

The present invention is used when inserting a small-diameter snow pole into a buried cylinder for holding a conventional large-diameter snow pole, and allows the small-diameter snow pole to be planted straight without wobbling. The purpose of the present invention is to provide a spacer for installing snow poles that can be used to install snow poles.

Hereinafter, the present invention will be explained with reference to drawings showing embodiments.

1 and 2 show examples of the spacer of the present invention.

The spacer 2, which has a flange-shaped portion 1 formed at its upper end, is entirely made of plastic or resin, and has a hollow cylinder formed with a space 5 between an outer wall 3 and an inner wall 4 below the flange-shaped portion 2. It has a section 6.

A ventilation hole 7a is provided between the lower edge of the outer wall 3 and the lower edge of the inner wall 4.
A bottom plate 7 is provided to partition the inside and outside of the space 5.

At three locations on the upper part of the outer peripheral surface of the outer wall 3, there are protrusions 8, approximately equally spaced.
8 is prominent.

The lower end portions 8a of the protrusions 8, 8 are each inclined downward so that the height of the protrusions decreases.

On the other hand, protrusions 9, 9 are formed at three locations on the lower part of the inner peripheral surface of the inner wall 4 at approximately equal intervals.

The upper end portions 9a of the protrusions 9, 9 are each inclined upward so that the height of the protrusions decreases.

Next, a description will be given of an operation for planting a small-diameter snow pole in a large-diameter holding cylinder using the snow pole installation spacer constructed as described above.

First, as shown in Figure 3, a cylinder 1 is buried in the road shoulder.
Insert spacer 2 into 0.

The outer diameter of the cylindrical portion 6 of this spacer 2 is determined in advance by this cylinder 10.
Although the spacer 2 is formed somewhat loosely according to the inner diameter of the cylinder 10, the spacer 2 fits inside the cylinder 10 without wobbling because the protrusions 8, 8 press against the inner peripheral surface of the cylinder 10 and the outer wall 3 deforms elastically. match.

In addition, the flange-like portion 1 at the upper end of the spacer 2 is shaped like a cylinder 10.
Since the spacer 2 contacts the upper end of the cylinder 10, the spacer 2 does not fall into the cylinder 10.

Once the spacer 2 has been inserted in this way, the lower end of the snow pole 11 is then inserted inside the inner wall 4 of the spacer 2.

In this case as well, the inner diameter of the inner wall 4 is shaped in advance to be slightly larger than the outer diameter of the snow pole 11, but due to the pressure contact of the protrusions 9 and the elastic deformation of the inner wall 4, the snow pole 11 is held inside this inner wall 4 without wobbling.

The snow pole installation spacer of the present invention is structured and works as described above, so a small diameter snow pole can be installed without wobbling in a conventional large diameter snow pole installation cylinder, making it practical. The above effect is great.

Claims (1)

[Scope of utility model registration request] The outer wall 3 and the inner wall 4 are placed concentrically with a space 5 between them, and the lower end of the space 5 is closed with a bottom plate 7 having a ventilation hole 7a.
The upper end has a center hole having the same diameter as the inner wall 4, extends outward from the inner wall 4, and is closed with a flange-like portion 1 that is connected to the outer wall 3, forming a cylindrical portion 6 with synthetic resin. At three locations on the upper part of the outer circumferential surface of the snow pole, protrusions 8, 8 are integrally formed, the lower end 8a of which is inclined downwardly so as to be elastically inscribed in the existing large diameter snow pole installation cylinder. At three locations on the lower part of the inner circumferential surface of the inner wall 4, protrusions 9, 9 are integrally formed, which elastically circumscribe a small-diameter snow pole inserted with the upper end 9a slanting downward toward the top. A spacer for installing a snow pole.
