Description

{Locking Device for Doors}

More particularly, the present invention relates to a locking device for a window, and more particularly, to a locking device for locking a window when the window frame is moved to a predetermined position when the window is closed, And to maintain the airtightness by securing a strong adhesion between the vertical close part and the vertical rail.

Generally, at least one door or window is installed inside and outside the building to divide / separate the indoor space or to divide / separate the indoor and the outdoor, and by opening and closing them, the user can go out and circulate the air .

In the above-mentioned conventional window, the window frame and the window frame overlap (door and door) or the window frame and the door frame (door and door frame) And the latching ring can be hooked to the latching piece in a state in which the window (door) is closed, so that the locking mechanism of the window is closed when the window system is closed . An example of such a conventional locking device is disclosed in Patent No. 10-0882419.

The conventional locking device for a window has a structure in which a latching piece and a latching ring are installed around a knob, and the latching ring is directly connected to the rotation of the knob so that a plurality of flat plates, And connection devices. That is, since the rotational movement of the handle is required to include a plurality of components for converting the intermediate connection piece formed in the longitudinal direction into the upward and downward translation movement and finally transmitting the upward and downward translation movement of the intermediate connection piece to the up- There is a problem that the cost is excessive.

In the case of a window having a height larger than that of a general person, since the handle is located at a position that is less than 1/2 of the height of the door and is located at a position deviated from the center of the door, The locking device may be disproportionately placed, resulting in a slight swing at the door.

In addition, the conventional locking device for a window is provided with a latching ring projecting from the outer surface of the vertical frame, which is not preferable for appearance, and there is a risk that the locking ring may be damaged by collision or may be injured when an infant is actuated.

In addition, in the conventional window locking device, when the user directly manipulates the latch ring (i.e., the user moves the door to the doors with a predetermined force and then pushes the door with force larger than the force for moving the door for restraint, The locking device may not be switched to the locked state due to the carelessness of the user when the user does not perform the locking operation. Accordingly, due to the fear of theft and the external wind pressure, And the noise is generated.

In addition, when the locking lever is used for a long period of time, it is difficult to maintain the locked state completely because the locking ring and the locking lever are loosened, so that it is inconvenient to repair the locking device through periodic inspection.

In addition, since the retaining ring and the retaining piece are assembled to the window frame or the door in a state of being fixedly coupled to the different window frame or the door frame, respectively, There is a possibility that the protruding hook and the hook are damaged or broken.
