2. Description of the Related Art Conventionally, as described in Japanese Utility Model Publication No. 3-20330, a core column called a rotating body is screwed to the bottom of an outer cylinder,
There has been proposed a car stop in which a pillar is inserted into a gap between the inner circumference of the outer cylinder and the outer circumference of the core pillar to stand. In addition, it is generally known that a detachable cap is attached to the upper end of the outer cylinder, or a cap that can be opened with a hinge is used to prevent dust and dirt from entering the outer cylinder when the support is not erected. I have.

[0003]

However, in the above-mentioned structure, when the support is not erected, it is a fair fairness 3-20330.
In the case of the one described in the official gazette, there is a gap between the inner circumference of the outer cylinder and the outer circumference of the core column, so the prevention of the inflow of earth and sand is incomplete. The management of the cap was troublesome at that time, and in the case of a hinged cap that could be opened, the cap was exposed on the ground and the scenery was not good, and there was a problem for pedestrian safety. Further, since there is a gap between the outer cylinder and the column, rattling occurs when the column is erected.

[0004]

The car stop of the present invention is a detachable car stop, in which an outer cylinder for vertically arranging a pillar is buried in the ground, and a core post having a lid plate formed on the upper part thereof is provided. Standing on the bottom surface of the outer cylinder, the outer diameter of the lid plate is slightly smaller than the inner diameter of the column, and a flexible body is attached to the upper end of the outer cylinder or the upper surface of the lid plate to form an outer cylinder. The lower part of the column is inserted and fixed so as to bend the flexible body in the gap between the core columns, and when the car stop is not used, the flexible body causes the earth and sand to flow into the outer cylinder. In addition to preventing the above, it is not necessary to remove the cap when the pillar is erected, there is no need to manage the cap, the cap does not project above the ground, the scenery is good, and pedestrians do not trip over and Since the flexible body is interposed in the space between the columns, the columns do not rattle.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below. FIG. 1 is a longitudinal sectional view of an essential part showing an example of an embodiment of a car stop of the present invention.

Reference numeral 1 denotes an outer cylinder, which is embedded in one or a plurality of pieces in the ground, and a pillar 2 is inserted and erected inside the outer cylinder when a car stop is used. The outer cylinder 1 is cylindrical and has a bottom portion 11 closed and a flange portion 12 formed on the upper portion. Outer cylinder 1
A core 3 is formed on the bottom 11 of the. The outer diameter of the core pillar 3 is slightly smaller than the inner diameter of the outer cylinder 1, and is provided on the inner surface of the outer cylinder 1 so as to be coaxial with the center axis of the outer cylinder 1. A cover plate 31 is formed on the top of the core pillar 3. The height of the core column 3 is substantially the same as the height of the outer cylinder 1, and the cover plate 31 is at the same level as the flange portion 12. An elastic plate such as a rubber plate is adhered to the flange portion to form the flexible body 4. The flexible body 4 is a donut-shaped plate in which a hole having the same diameter as the outer diameter of the lid plate 31 or a slightly smaller diameter is formed in the center thereof. The outer cylinder 1 and the core 3 are usually produced by adhering a metal plate such as a steel plate or a stainless steel plate to a metal pipe such as a steel pipe or a stainless steel pipe by welding or the like, and appropriately surface-treated. As described above, the flexible body 4 may be formed only by forming a hole in the elastic plate, but it is more preferable if the slits 41 are radially formed as shown in FIG. 3 because the flexibility is improved.

Another example of the embodiment of the present invention will be described below. FIG. 2 is a longitudinal cross-sectional view of a main part showing another example of the embodiment of the car stop of the present invention.
