Description

TECHNICAL FIELD The present invention relates to a cone-shaped post that is used to demarcate special areas such as passageways and material storage areas, particularly on roads, construction sites, event venues, and the like.

By arranging the above-mentioned cone-shaped struts along the area to be partitioned by a plurality of cone-shaped struts, a specific area is set, and when canceling the above-mentioned specific area, the This is done by retrieving multiple cone-shaped struts.

Therefore, it is widely used because it is possible to easily set and cancel the specific area and does not require any special work such as a fence.

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

In addition, the base portion and the strut portion have a cavity whose interior is opened downward, and the strut portion of one cone-shaped strut is covered with the strut portion of the other cone-shaped strut in the cavity. A plurality of cone-shaped struts are stacked and housed by fitting them over each other.

Utility Model Registration No. 3029459

In the prior art described above, by stacking and storing a plurality of cone-shaped posts, the area occupied in the stored state is reduced, and the effect of reducing the occupied space during storage and transportation is obtained.

However, even with such a conventional cone-shaped post, there are still the following problems to be solved.

That is, the base of the cone-shaped support is provided with a square-shaped base in order to ensure stable self-reliance at the time of installation as described above.
If a plurality of cone-shaped support columns having such a structure are casually stacked while being fitted together, there is a problem that the orientations of the vertically overlapping base portions become sparse.

If the directions of the base portions are not aligned in this way, the corner portion of one base portion will protrude outward from the side edge of the other between the base portions positioned above and below.

In addition, since the corner protrudes from the side, the storage space for the plurality of stacked cone-shaped columns is widened.

In order to solve such a problem, when stacking the plurality of cone-shaped posts, the direction of the upper cone-shaped posts is adjusted so that the side edges of the bases of the respective cone-shaped posts are aligned with each other, while the lower cone-shaped posts are aligned. Since it is necessary to cover the cone-shaped support, the operation of storing the cone-shaped support becomes complicated.

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

Here, it is assumed that the contact pressure between the support portions becomes excessively large when the cone-shaped support is applied with a large force or when it is suddenly dropped.
Also, the cone-shaped struts may be stacked in groups of 20 to 30. In this case, the load applied to the lower cone-shaped struts increases, increasing the aforementioned contact pressure.

In this way, when the support sections are fitted with a large contact pressure over almost the entire surface, a large force is required to separate the cone-shaped support, and as a result, the installation work of the cone-shaped support is required. is complicated.

The present invention has been made to solve the problems remaining in the above-described conventional technology, and the square-shaped base part ensures the stability of the cone-shaped post when it is installed, and the base part when stored. It is an object of the present invention to facilitate the aligning operation and to simplify the separating operation of a plurality of stacked cone-shaped posts.

In order to solve the above-described problems, the cone-shaped post of the present invention comprises a substantially square-shaped base and a substantially conical support that is erected integrally upward from a substantially central portion of the base. At least one of the side edges of the base portion is provided with a posture regulating piece directed obliquely upward, and between the side edge of the base portion and the strut portion, the upward direction of the base portion is provided. A protruding gap holding projection is provided.

The cone-shaped column of the present invention is installed with the base portion placed on the installation surface.
In this state, since the base portion is formed in a substantially square shape, each side of the base portion prevents tilting and enables stable installation.

At the time of recovery, one cone-shaped support is lifted and overlapped so that the support part of another cone-shaped support enters the cavity.

At this time, by rotating the superimposed cone-shaped support around its center axis, the outer surface of the attitude control piece of the upper cone-shaped support is made to face the surface of the attitude control piece of the lower cone-shaped support.

When the upper cone-shaped support is lowered, the attitude control pieces of the upper cone-shaped support are stacked while being guided by the attitude control pieces of the lower cone-shaped support.

Here, since the posture regulating pieces are in a fixed positional relationship with respect to the side edges of the base portion, as described above, the posture regulating pieces of the upper cone-shaped support are aligned with the posture of the lower cone-shaped support. By being guided by the restricting pieces, the base portions of the upper and lower cone-shaped columns are also stacked with their side edges and corners aligned in the vertical direction.

Therefore, when the cone-shaped posts are stacked, the respective base portions are aligned, and the area occupied during storage is within the range of the shape of the base portions.

In this way, the operation of aligning the orientation of the base portions of the overlapping cone-shaped struts is a very simple operation.

On the other hand, when the plurality of cone-shaped columns are superimposed, the base portion of the upper cone-shaped column is brought into contact with the gap holding projection 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 position of both cone-shaped columns in the vertical direction is regulated, and the gap or contact pressure between the superimposed upper and lower column portions is constant. is held to

Here, by adjusting the height of the gap holding projection, the amount of gap between the upper and lower support columns is adjusted, or the contact pressure therebetween is adjusted.

As a result, the plurality of stacked cone-shaped struts are stacked while forming a gap therebetween or with a predetermined contact pressure.

When stacking the upper and lower cone-shaped pillars in contact with each other, by appropriately setting the contact pressure between the two, when carrying the stacked cone-shaped pillars, the contact between these cone-shaped pillars can be reduced. It is possible to suppress misalignment and facilitate its carrying.

In addition, the above-mentioned contact pressure is the minimum contact pressure necessary for carrying the cone-shaped posts, so that the resistance when separating the stacked cone-shaped posts is minimized, and the cone-shaped posts can be separated smoothly. can be

It is preferable that the attitude control pieces are provided on a plurality of side edges of the base portion.
With such a configuration, when the cone-shaped struts are superimposed, the lower cone-shaped strut guides the upper cone-shaped strut at a plurality of locations, thereby allowing the lower cone-shaped strut to guide the upper cone-shaped strut. It is possible to enhance the relative position adjustment action about the central axis with respect to the strut.

Moreover, it is preferable that the posture regulating piece is provided over substantially the entire length of the side edge of the base portion.
With such a configuration, when a plurality of cone-shaped columns are superimposed, the guiding surface of the lower cone-shaped columns can be enlarged, and a stable guiding function can be obtained.

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

It is preferable that the gap holding protrusions are provided between the supporting column and the plurality of side edges of the base.
With such a configuration, the upper cone-shaped support is supported at a plurality of locations by the gap holding projections of the overlapping lower cone-shaped support, so that the support of the upper cone-shaped support can be stabilized. can.

The gap holding protrusions may be linearly provided along the side edge of the base portion.
By adopting such a configuration, it is possible to further stabilize the support by increasing the support area of the gap holding projections that support the superimposed upper cone-shaped support.

A plurality of the gap holding projections may be provided at intervals along the side edge of the base portion.
By adopting such a configuration, water and dust on the base portion between the support portion can be easily discharged to the side edge of the base portion.
