Description
BACKGROUND OF THE
In general, a sliding door installed in a living room or a veranda is automatically locked when a window is closed, and a lock is provided to open the window by releasing the lock state by manual operation of the handle.
Conventional door handles are largely lever-type so as to release a locked state and to apply a force to the gripped hands so that a large door with a large size and a heavy weight can be opened more conveniently.
In the conventional lever-type door handle, when the handle is rotated to open the door, the operation pin rotates the stopper of the locking device, the stopper operates the operation member having the operation piece or the gear, and the operation member then operates the latch The lock state is canceled.
When the locked state of the door is released, the door is moved in the horizontal direction by the force acting on the lever and is opened.
In this process, the angle of rotation of the conventional door handle is usually maintained at angle of 36 to 42 degrees, and therefore, the direction of action of the force applied to the handle is close to the direction of action (horizontal direction) So that the strength of the force for opening the door is largely influenced, so that the door of the door can not be easily opened by the fragile housewife or the young child as the door is opened.
For example, "a support structure for a window locking device" of
SUMMARY OF THE INVENTION Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and it is an object of the present invention to provide a sliding door which can be easily opened by opening and closing the upper and lower latches with minimum rotation of the lever operated to open the sliding door And to provide a door locking device which can simplify the structure of the door and improve the convenience of assembly and productivity.
According to an aspect of the present invention, there is provided a door locking device comprising a main body mounted on a sliding door, a stopper having a shaft hole formed at a center thereof in a through hole of the main body, A pair of upper and lower brackets coupled to the upper and lower fixing shafts and having a latching rib and a returning rib, a coil spring for assisting rotation of the latch, a rotating body that is operated by being inserted into the shaft hole of the stopper, A cover having a pin, a cover closing the opening portion of the body, and a hooking portion mounted on the door frame so as to fix the door when the latching rib of the latch is inserted; A guide pin is protruded from the upper and lower portions of the through-hole of the main body, and a guide hole is formed in the stopper so as to be linearly moved after being inserted into the guide pin; A coil spring interposed in a guide pin of the main body is provided to provide an elastic force when the stopper linearly moves; Wherein the shaft hole inner diameter of the stopper and the outer diameter of the rotating body are provided at two to three places where the engaging step is provided at one side and the spiral step is formed at the other side, A stepped upper and a lower engaging groove are formed in the latch, and upper and lower ends of the stopper come into contact with the upper and lower latching grooves; When the stopper is linearly moved backward and forward by the operation of each of the rotator operated by the artificial rotational force of the handle and the actuation of the latch by the help of the contact with the hook, the upper and lower ends of the stopper are engaged with the upper catching groove The latching rib of the latch is released from the latching opening to allow the door to be opened. When the upper and lower ends of the stopper are positioned in the upper latching groove of the latch, the latching rib of the latching latch is inserted into the latching opening to maintain the locked state of the door It can be a technical feature.
According to the present invention, when the rotating body is rotated by the operation of the handle, when the spiral end of the rotating body rotating by the small force is changed to the linear motion pushing the spiral end of the stopper, the upper and lower ends of the stopper are engaged Since the door can be easily opened by the operation of the stopper due to the small rotation of the rotating body, the rotation angle of the handle for operating the rotating body, which is the direction of action of the force, Since it is closer to the horizontal direction than the conventional one, convenience for minimizing energy consumption required to open the moving door is provided, and its structure is simple, which is easy to manufacture and assemble, which is very economical.
