Abstract

PURPOSE:To make the opening or closing of a gate easily and thoroughly performable by suspensibly supporting a freely turnable arm on one side of paired gate posts, and installing a chain wheel, being free of drawing in-and-out motion, in the other one. CONSTITUTION:A freely turnable arm 3 is suspensibly supported on one side gate 1 of a gate, while a chain wheel 5, winding a chain 4 so as to be free of drawing in-and-out motion, is installed in the other side gate post 2. When the chain wheel 5 is driven and the chain 4 is drawn in the gate post 2, an arm 3 suspended on the gate post 1 is overhung to the gate center as its tip is pulled by the chain 4, thus the gate is closed. When the wheel 5 is rotated in reverse and the chain 4 is delivered, a tip of the chain 4 is drawn up to a base of the gate post 1 by dint of energizing force of the arm 3 so that the whole chain 4 lies on a ground surface, opening the gate to the full.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to an improvement of a chain gate suitable for entrances and exits of automobile parking lots and the like.

Prior Art and Problems In the conventional gate of this type, a chain G41 is loosely connected between one side gate post (1) and the other side gate post (21) as shown in Fig. 3.
There are some that have been installed.

In Fig. 3, the solid line indicates the "closed gate state" where cars cannot pass through, and the chain (4) is stretched. On the other hand, the chain line indicates the "open gate state" where cars etc. can pass through.
The state of the chain is shown, with most of the chain (l/8) lying on the ground, but only the part near the side gatepost (1) floating in the air and slanted.

This is the chain foil installed on the other side gatepost (a).
Even when the chain (A) is extended by operating the chain 51, the center of the chain reaches the ground surface, and both sides of the chain are supported diagonally. Even if you try to lower this diagonal part to the ground surface and further extend the chain (2), the center part of the chain (A) does not move, so only the chain (A) on the foil (9 side) descends to the ground surface, and the opposite side This is because the chain (4) is supported diagonally and does not fall.

Means for Solving the Problems This invention solves the above problems with extremely simple means. When "closing the gate", it is enough to tension the chain (2) as before, and when "opening" the gate, it is enough to tension the chain (2). By simply letting out the chain (a), the entire chain descends to the ground, providing a chain gate that can open the entire gate.

That is, the present invention provides, in a gate consisting of a pair of gateposts, a rotatable arm is suspended and supported on the four gateposts,
The other side gatepost is equipped with a chain foil that can freely retract and extend the chain, and the tip of the chain wound around the chain foil is the tip of the arm! ! The gist is the structure of ``Chien Gate,'' which is characterized by the fact that it is dressed up.

Operation This invention is constructed as described above, so when the chain wheel is driven and the chain is retracted into the other side gate post, -
The end of the arm, which is suspended from the side gate post, is pulled by the chain and extends to the center of the gate.
The tip of the chain is pulled to the base of the fourteen gate pillars by the force of the arm, and the entire chain lies on the ground, and the gate is completely opened.

Embodiment To explain this invention with reference to FIG. 1, the gate consists of fourteen cylindrical columns (1) and a gate post (J) on the other side, and an arm (3) is suspended and supported on the four gate posts (1). It is a chain, and the other side gatepost (a
It is wound around a chain foil (5) provided in the. This chain foil (9 can be operated freely with a caustic wire or wired)
8 drive (not shown). The tip of the chain 4 is attached to the tip of the arm (3). When this chain (4) is retracted into the other side gate post f21 by the boil (5), the arm (3) is pulled by the chain at its tip and turns upward rij1 to close the gate t. Become.

Next, when the foil (4 is reversely rotated and chain 0) is let out, the arm (3) hangs down due to its own bias and the chain (
Guide the tip of 4) to the base of the 14 gate pillars (]) and open the gate. If the arm (3) is not sufficiently biased by its own weight, the weight port may be used via the wire (6), for example, as shown in [2]A.

Although the present invention has been described as a pair of gateposts full [2], it goes without saying that the present invention also applies to buildings or other objects.

Effects of the Invention ■ As is clear from the description, when according to the present invention, by extending the chain and retracting it, the game 1- is opened,
j] There is an effect that the chain can perform very easily and completely.

Claims (1)

[Claims] In a gate consisting of a pair of gateposts, a rotatable arm is suspended and supported on one side of the gatepost, and a chain foil is provided on the other side of the gatepost, and the chain can be freely retracted and retracted, and the tip of the chain is wound around the chain foil. A chain gate characterized by being connected to the tip of the arm.
