Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a fence post on which a chain can be attached and detached.

[Conventional technology]

Traditionally, this type of fence post was made in 1983.
In the former, a keyhole-shaped locking part is formed on the upper side of the pole, and two discs connected to the tip of the chain are attached to the rod body. In the latter method, a window hole is formed on the upper side of the pole, and a key is operated inside the pole to protrude into the inside of the window hole. A lock rod was provided, and an end member that was inserted into the window hole and engaged with the lock rod was connected to the tip of the chain.

However, in the former method, the connecting member having an E-shaped cross section is simply locked in the keyhole-shaped locking portion, and there is a high risk that the connecting member will easily separate from the locking portion.

In addition, in the latter method, the end member inserted into the window hole is locked to the lock rod, so the fear of the chain coming off is eliminated, but the lock rod is raised with the end member inserted into the window hole. It was impossible to lock the end member unless the key was operated.

[The problem that the idea aims to solve]

According to the conventional method, if the chain is easy to connect, there is a risk of separation, and if the separation is resolved, the chain installation becomes complicated.
The problem was that the temporary fixing state could not be obtained.

[Means to solve the problem]

The present invention consists of a hollow pole that stands on the ground, a locking window that is formed on the upper side of the pole and has a T-shape with vertically long holes and horizontally long holes, and a locking window that rotates inwardly above the locking window. It consists of a cam plate that is freely attached and can open and close a horizontally elongated hole, and an operating part that faces the outer surface of the pole and rotates the cam plate.

[Effect]

Then, the most advanced ring of the chain is arranged horizontally and inserted into the horizontally elongated hole opened by operating the cam plate, and the ring that continues from this is arranged vertically and inserted into the vertically elongated hole, and the most advanced ring is inserted into the vertically elongated hole. Place the ring on the back of the vertical hole and temporarily fasten the chain to the locking window.

In this state, the cam plate is rotated to close the horizontally elongated hole, thereby preventing the vertical ring from rising, that is, the most distal ring from separating from the horizontally long hole.

Furthermore, by operating the cam plate to open the horizontally long hole, the most advanced ring can be removed from the horizontally long hole.

〔Example〕

Hereinafter, an embodiment of the present invention will be described based on the drawings. 1 is a hollow pole installed on the ground;
It can be freely immersed into an outer cylinder 2 buried underground.

Reference numeral 3 denotes a T-shaped locking window formed on the upper side surface of the pole 1, which is formed by a horizontally elongated hole 4 and a vertically elongated hole 5.

Reference numeral 6 denotes a locking mechanism provided on the upper inner side of the locking window 3. A rectangular cam plate 7 that can freely open and close the horizontally elongated hole 4 is rotatably attached to the locking mechanism, and its operation part 8 is placed on the upper outer side of the locking window 3. I'm letting you do it. Reference numeral 9 denotes a chain stretched between the poles 1, and at its tip, a connecting member 11 connected to a locking body 10 that is fitted into the hollow pole 1 through the horizontally long hole 4 is connected. , the connecting member 11 is connected to the horizontal locking body 10 by changing the angle in the vertical direction so as to be inserted into the vertically elongated hole 5. That is, the locking body 10 has a horizontal shape with respect to the connecting member 11 inserted into the vertical hole 5, and the relationship between the locking body 10 and the connecting member 11 is the same as that of the rings forming the chain 9. .
The other end of the chain 9 that is locked to the locking window 3 is housed in the adjacent pole 1 so as to be freely retractable, and is inside the window 12 formed on the opposite side of the locking window 3 of the pole 1. The locking body 10 of the chain 9 is fixedly attached to the communication hole 14 of the empty chamber 13 provided in the . 15 is a stopper attached to the rear end of the chain 9.

In the embodiment shown in the drawings, the pole 1 has a circular cross section, but it may also have a rectangular cross section.

[Effect of idea]

As mentioned above, this invention has a T on the upper side of the pole.
By forming a letter-shaped locking window, the most advanced ring of the chain can be inserted through the horizontally long hole of this locking window, and by inserting the next ring into the vertically long hole, the most advanced ring can be inserted into the vertically long hole. located on the back of the chain, the chain can be easily temporarily secured to the locking window, and the chain can be tensioned without the need for a special connecting device at the end of the chain. It is also possible to use connectors formed in a vertical and horizontal relationship.

In addition, since a cam plate that can freely open and close the horizontally elongated hole is rotatably attached to the upper inner side of the locking window, it is possible to open and close the horizontally elongated hole from the topmost ring of the chain, which is located on the back of the vertically elongated hole and is temporarily secured. It is possible to prevent the withdrawal of

Moreover, the operation of rotating the cam plate is separate from the operation of locking the end of the chain to the locking window, and each operation can be easily and reliably performed in a separate state.
