Description

The present invention relates to a cone-shaped strut used for partitioning a special area such as a passage or a material storage place, particularly on a road, a construction site, an event venue, or the like.

The above-mentioned cone-shaped struts are arranged along an area to be partitioned by a plurality of cone-shaped struts so as to set a specific area, and when the above-mentioned specific area is released, the above-mentioned This is done by collecting multiple cone-shaped stanchions.

Therefore, it is widely used because it is possible to easily set and release a specific area and it does not require special construction such as a fence.

By the way, as shown in Patent Document 1, the above-mentioned cone-shaped strut is provided with a square-shaped base portion in order to ensure stability at the time of installation, and a conical strut portion is projected on the base portion. It has become.

Further, the base portion and the strut portion have a cavity whose inside is open downward so as to cover the strut portion of one cone-shaped strut in the cavity and the strut portion of another cone-shaped strut. A plurality of cone-shaped columns are stacked and stored by covering them with each other and fitting them to each other.

In the above-mentioned conventional technique, by stacking and storing a plurality of cone-shaped columns upward, the occupied area in the stored state is reduced, and the effect of reducing the occupied space at the time of storage or transportation is obtained.

However, even with such a conventional cone-shaped support, the following problems to be improved still remain.

That is, as described above, a square-shaped base portion is provided at the base of the cone-shaped column in order to ensure stable independence at the time of installation.
When a plurality of cone-shaped columns having such a configuration are randomly stacked while being fitted to each other, there is a problem that the orientation of the vertically overlapping base portions becomes sparse.

When the orientations of the base portions are not uniform in this way, the corner portions of one base portion are projected outward from the other side edge between the base portions located above and below.

Then, the storage space for the plurality of stacked cone-shaped columns is expanded by the amount that the corner portion protrudes from the side portion.

In order to solve such a problem, when stacking the plurality of cone-shaped columns, the lower side of the cone-shaped columns is adjusted so that the side edges of the bases of the cone-shaped columns are aligned with each other. It is necessary to cover the cone-shaped support, which makes the storage work of the cone-shaped support complicated.

On the other hand, in the plurality of cone-shaped struts stacked as described above, the outer surface of the stanchion portion of the inner cone-shaped stanchion is brought into surface contact with the inner surface of the outer stanchion portion over almost the entire surface.

Here, it is assumed that the contact pressure between the strut portions becomes excessively large when the force for covering the cone-shaped strut is large or when the force is suddenly dropped.
Further, 20 to 30 cone-shaped columns may be stacked and stored, and in this case, the load applied to the lower cone-shaped column becomes large and the above-mentioned contact pressure increases.

In this way, when the support columns are fitted to each other by a large contact pressure over almost the entire surface, a large force is required to separate these cone-type columns, and as a result, the installation work of the cone-type columns is required. Is complicated.

The present invention has been made to solve the problems remaining in the above-mentioned conventional technique, and the square-shaped base portion ensures stability when the cone-shaped support is installed, and the base portion is stored.

In this way, the work of aligning the orientation of the base portions of the cone-shaped columns to be overlapped is extremely simple.

On the other hand, when these a plurality of cone-shaped columns are overlapped with each other, the base portion of the upper cone-shaped column is brought into contact with the gap holding protrusion provided on the base portion of the lower cone-shaped column.

When the upper base portion abuts on the upper portion of the lower gap holding protrusion in this way, the relative positions of both cone-shaped columns in the vertical direction are restricted, and the distance or contact pressure between the upper and lower columns to be overlapped is constant. Is held in.

Here, by adjusting the height of the gap holding protrusion, the amount of gap between the upper and lower strut portions is adjusted, or the contact pressure between them is adjusted.

As a result, the plurality of cone-shaped columns to be stacked are stacked while forming a gap between them or at a predetermined contact pressure.

Then, when stacking in a state where the upper and lower cone-shaped columns are in contact with each other, by appropriately setting the contact pressure between the two, when carrying a plurality of stacked cone-shaped columns, between these cone-shaped columns. It is possible to suppress the deviation and make it easy to carry.

In addition, the above-mentioned contact pressure is set to the minimum contact pressure required for carrying the cone-type columns, so that the resistance when separating the stacked cone-type columns is minimized, and the separation of the cone-type columns is smooth. Can be.

It is preferable that the posture control piece is provided on a plurality of side edges of the base portion.

It is possible to enhance the relative position adjustment action around the central axis with respect to the column.

Further, it is preferable to provide the posture control piece over almost the entire length of the side edge of the base portion.
With such a configuration, when a plurality of cone-shaped columns are stacked, the guide surface of the lower cone-shaped columns can be enlarged to obtain a stable guide function.

A plurality of the posture control pieces may be provided at intervals along the side edges of the base portion.
With such a configuration, water, dust, etc. on the base portion can be easily discharged from between the posture control pieces to the outside of the base portion.

It is preferable that the gap holding protrusion is provided between the support column portion and the plurality of side edges of the base portion.
