Description

[Detailed description of the invention] Industrial application field This invention is intended to be buried underground with an upper opening that can be opened and closed by a lid facing the ground surface, thereby restricting the passage of people or vehicles. The present invention relates to a support on which a pole can be freely inserted and removed.

BACKGROUND TECHNOLOGY Conventionally, in this type of support, a lid body that can freely open and close the upper opening of the cylindrical body is attached by a shaft, so that the opening can be closed when the pole is not erected.

Problems that the invention aims to solve: However, since the lid body is attached to the cylindrical body irremovably, and the shaft is buried underground, it is impossible to replace the lid body if it breaks. In addition, when the lid was opened, the surface of the lid came into contact with the edge of the opening and remained open, resulting in damage, and in either case, the lid was unsightly.

Means for Solving the Problems Therefore, the present invention aims to provide a support body with a replaceable lid, which consists of a cylindrical main body with a wide mouth opening at the top and a wide mouth part connected to the upper end. , a removable seat plate that covers the periphery of the wide opening and has a through hole in the center, a recess cut into a part of the seat plate to communicate with the through hole, and a tongue piece that fits into the recess. It consists of a cover body with a through hole formed protruding from the edge thereof, and a shaft that supports a tongue piece below the recess and supports the cover body on a seat plate so as to be openable and closable.

Further, it is preferable that the end of the tongue piece is extended downward and a stopper is provided on the side edge thereof.

Function The cylindrical main body 1 is buried in the ground with the opening 2 of the wide mouth part 3 facing the ground surface, and the seat plate 5 to which the lid body 10 is attached so as to be openable and closable is removably fixed to the opening 2. Then, open the lid 10 and open the through hole 7 of the seat plate 5.
The lower part of the pole 17 is inserted and supported.
When the pole 17 is not erected, the lid 10 is closed to prevent obstacles to traffic and to prevent stones and the like from falling.

In addition, if the end of the tongue piece 11 is extended downward 12 and a stopper 13 is provided on the side edge of the extended part 12, the stopper 13 will hit the seat plate 5, causing the lid 10 to open excessively. prevent.

Embodiment An embodiment will be described below with reference to the drawings. Reference numeral 1 denotes a cylindrical body having an opening 2 at the top and a wide mouth portion 3 attached to the upper end, and a bottom plate 4 disposed at the lower end.
Reference numeral 5 designates a seat plate attached to the upper end of the wide mouth portion 3 with screws 6, and a through hole 7 is provided in the center, and a downward step portion 8 is formed at the edge of the through hole 7. A part of this through hole 7 is cut outward to form a recess 9. 10 connects the edge to the stepped portion 8 of the seat plate 5
The lid body is placed on the seat plate 5 to close the through hole 7, and a part of its edge extends outward to form a tongue piece 11 that fits into the recess 9 of the seat plate 5. Reference numeral 12 denotes an extension of the end of the tongue 11 bent downward, and its both side edges are extended to form a stopper 13. 14 is a reinforcing material provided on the back side of the lid body 10;
Both ends are fixed to the back surface of the seat plate 5 between and the extension part 12, and the lid body 10 can be opened and closed by holding a shaft 15 extending below the recessed part 9. 16 is the lid body 10
17 is a pole set on the ground, 18
is a locking device.

Although the embodiments in the drawings show circular cross-sections, it is also possible to use square cross-sections.

Effects In the present invention, the seat plate 5 to which the lid 10 is attached so that it can be opened and closed is removably attached to the wide opening 3 at the upper end of the main body 1, so the shaft 15 that allows the lid 10 to be opened and closed is attached to the wide opening 3. Since the main body 1 is located inside the ground, there is no problem with burying the main body 1 underground, and reliable opening and closing operations can be performed.

Even if the lid body 10 is damaged, the seat plate 5 can be removed and replaced easily. moreover,
The wide mouth portion 3 has a space below the seat plate 5 and can be used as an engaging portion of a locking device 18 that prevents the pole 17 erected from being pulled out.

Further, the end portion of the tongue piece 11 is extended downward 12,
By providing the stopper 13 on the side edge, the stopper 13 is attached to the seat plate 5 when the lid body 10 is opened.
In this case, the lid body 10 can be maintained in a state along the upright pole 17 so as not to become an obstacle to traffic.

As described above, the present invention allows the lid 10 to be used without damage or damage, and can be buried underground with the opening facing the ground surface and used as a support on which the pole 17 can be erected as needed. Beneficial.
