Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a car stop fence installed at the entrance to a parking lot or park.

[Conventional technology]

Conventionally, in such fences, a fence chain or fence bar that spans between the upper ends of adjacent fence posts connects the fence posts by engaging hooks attached to the fence posts or inserting rings. It was configured to connect to the top end.

[Problem that the invention attempts to solve]

However, when using the conventional fence, in order to open the entrance and exit so that people can pass through, as shown in the examples below, the fence posts are sunk and stored in cylinders buried underground, or as described below. As shown in another embodiment, it is difficult to dispose of the fence chains and bars when removing the fence posts from holes formed in the ground, that is, when removing the fence. In other words, in the case of the former, when the fence post is sunk and stored in an underground cylinder, either the fence chain or fence bar is removed from the fence post and sunk stored, or the fence chain or fence bar is sunk while connected to the fence post. However, when removing fence chains and fence bars from fence posts and storing them in a submerged position, store them in a place where people and cars cannot pass to prevent the removed fence chains and bars from being stepped on and damaged by people or cars. It is very inconvenient to secure a storage location and transport the fence chains and bars to the storage location. When storing the fence in a submerged manner, it is inevitable that the fence chains and fence bars will crawl on the ground where people and cars pass, and that the fence chains and fence bars will be stepped on by people and cars. It is easily damaged. On the other hand, in the latter case, either remove the fence chain or fence bar from the fence post, pull out the fence post, and remove it.
Alternatively, you can either pull out and remove the fence post with the fence chain connected to the fence post, but when you remove the fence chain or fence bar from the fence post and pull out the fence post and remove it,
Similarly to the above, it is very inconvenient in terms of securing a storage location for fence chains and fence bars and transporting them to the storage location, and when removing a fence post with the fence chain connected to the fence post, It's too heavy to actually do.

There is also a method of storing the fence chain inside the fence post by forming a hole in the lid fixed to the top of the fence post to allow the fence chain to be inserted into the fence post from above. When inserting into the fence post through the hole,
When the fence chain gets caught on the periphery of the hole, it bends and takes time to insert.

The fence according to the present invention was developed in view of the above-mentioned circumstances, and the purpose of the present invention is to provide a fence that can be easily and quickly set up and removed from entrances and exits, etc.

[Means for solving problems]

The characteristic structure of the fence according to the present invention is that a lid fixed to the top of a cylindrical fence post is inserted into the fence post from above with a fence bar extending between the top ends of adjacent fence posts in an upward and downward direction. A hole is formed in which the fence bar can be inserted, and a retaining portion is attached to the insertion side end of the fence bar to prevent the fence bar from being pulled out upwardly from the hole by coming into contact with the lid. is constructed such that it can be bent freely using a point slightly above the lid as a fulcrum when the retaining portion is in contact with the lid, and the effects thereof are as follows.

[Effect]

In other words, by inserting the fence bar into the fence post through the hole formed in the lid, the fence bar can be stored inside the fence post, so when removing the fence, the fence bar can be inserted and stored inside the fence post. This eliminates the need for a special storage location for the fence bars and the need to carry the fence bars to the storage location, and prevents the fence bars from being stepped on by people or vehicles, thereby preventing damage to the fence bars. Moreover,
The fence bar is not bendable like a fence chain,
Since it is straight and rigid, when the fence bar is inserted or removed through the hole formed in the lid, there is no chance of the fence bar getting caught on the periphery of the hole.

[Effect of idea]

Therefore, it has become possible to assemble and disassemble the fence easily and easily on site in a short period of time.

〔Example〕

Examples of the present invention will be described below.

As shown in Figure 4, it is cylindrical and has a lid 3 at its upper end.
A fence A is constructed by erecting a plurality of fence posts 1 with attached fence posts 1 at appropriate intervals and extending a fence bar 4 between the upper ends of adjacent fence posts 1.

As shown in FIG. 3, each of the fence posts 1 is held in a fixed tube 2 buried underground so as to be slidable between an upwardly protruding working position and a storage position retracted into the fixed tube 2. A position fixing tool 2A is attached to the upper end of the fixing tube 2 for fixing the fence post 1 pulled up to the working position.

As shown in FIG. 4, the fence bar 4 is divided into two parts 4A and 4B at its longitudinal center.

As shown in FIGS. 1 and 2, holes 3a are provided in the lid 3 of the fence post 1 through which the divided fence bar parts 4A and 4B can be inserted into the fence post 1 from above in an upwardly facing position. , 3a, and contact the lower ends of the divided fence bar portions 4A, 4B which are in an up-and-down attitude with the lower surface of the lid 3, so that the divided fence bars 4A,
When the divided fence bar portions 4A, 4B are housed in the fence post 1, the divided fence bar portions 4A are provided with retaining portions 7, 7 that prevent the portions 4B from being pulled out upward from the holes 3a, 3a, and at the upper end portions. , 4B from falling from the holes 3a, 3a are provided with retainers 5, 5 which also serve as lifting operation handles for the divided fence bar portions 4A, 4B, respectively. , 5 are in contact with the lid 3, the lid 3
It is configured to be able to bend freely by using the points slightly above the fulcrums R, R.

The retaining portion 7 is provided with a coil spring 8 that cushions the impact when the lid 3 is brought into contact with the lid 3.

Split fence bar parts 4A, 4 bent into horizontal position
The means for connecting the ends of B are shown in Figure 5 A, B,
As shown in C, a nut-like member 6A that can be threaded is attached to the end of one divided fence bar portion 4A, and a bolt-like member 6B is fixed to the end of the other divided fence bar 4B.
Attach the nut-shaped member 6A and bolt-shaped member 6B.
By screwing together the divided fence bar portion 4A,
This is a means for connecting 4Bs.

9 is a handle for pulling up the fence post 1, and 10 is a reflective tape.

[Another example]

As shown in FIG. 6, the fence A is constructed by inserting and erecting the fence posts 1 directly into holes H drilled in the ground without using the fixed tube 2.
