DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gate with a locking device using a dead bolt which can be locked and unlocked from inside and outside of the gate.

[0002]

2. Description of the Related Art Conventional locking methods for gates are generally known, such as kanuki or a drop lock of a type in which a rod-shaped object is dropped into a hole and inserted.

[0003]

In the conventional locking method using a kanuki or a locking method such as a drop lock, it is impossible to lock and unlock from both the outside and the inside of a site with a gate as a boundary. In addition to this, when a large sliding door is installed, a commercially available deadbolt-type key is attached to the vertical frame at the opening / closing end of the gate. As is well-known, it is easily destroyed due to shock at opening and closing and lack of latch strength, etc.,
Padlocks have been used for many years.

The present invention solves these problems, and enables locking and unlocking from both inside and outside positions of a gate, and since a key that locks with a deadbolt can be used, management using a master key common to buildings is also possible. Since the key body is fixed to the gate, it is invented for the purpose of providing a gate with a locking device that locks with a deadbolt that does not have to be attached and detached one by one like a cylinder padlock and there is no fear of loss. .
