Description

Window safety locking device for ventilation and fall prevention}

The present invention relates to a safety locking device for a window, and more particularly, by allowing the position of the window to be fixed in a state where the window is not wide open but only a certain width is opened, ventilation is performed even when there is no person in the room, It relates to a safety lock on the window for ventilation and fall prevention, which can be blocked from intrusion.

In general, the locking device of the Miseogi window is fixed and installed on the side of the frame side of the outer window, and the half-moon-shaped hook is rotatably installed on the side of the frame of the inner window to close the Miseogi window. It is configured to lock the window by rotating the half-moon hook by a certain angle and combining it with the hook shape. In addition, as another example of a locking device, a hook is fixed to the shift bar that is interlocked by the rotation of the handle, and a hook is installed on the window frame, and the hook on the shift bar is rotated by turning the handle while the window is completely closed. A method of being inserted into and caught on the provided catch is applied.

Therefore, there is a problem that the window locking device cannot be used when the window is not completely closed but only a certain width is opened, and it is not only inconvenient as a person has to lock the window by operating the locking device while the window is completely closed. If so, the window can be opened from the outside, so that the unauthorized intrusion of outsiders is possible and there is a problem that it is exposed to the risk of theft.

In order to solve such a problem, Korean Patent Registration No. 0934453 "Window Locking Device" technology appeared, which is installed on a window frame and is a window-side locking unit with perforations formed at regular intervals on a plate-like plate. And, it is composed of a window frame-side locking unit installed on the window frame and provided with a stop bar installed in a vertical direction, and the stop bar is inserted into the perforated hole of the plate, and the position of the window is fixed to limit movement. However, the above patent is not easy to apply because first, the structure is very complex,

Second, if the positions of the window-side locking unit and the window-frame-side locking unit are not exactly the same, the locking operation will not be performed.However, since the position of the hole formed in the plate is not visible from the outside, the operation lever is operated from the outside of the case where the stop bar is installed. There is a problem that it is difficult to rotate and insert the stop bar into the hole,

Third, since the operating levers are installed on the upper and lower frames of the window frame, there is a problem that in order to lock the window, squat and operate the operation lever, and then operate the operation lever installed on the upper frame again.

In order to solve the above problems, the applicant (inventor) of the present invention has developed Patent Registration No. 1557762 "a window device equipped with a spring for variable length of a lock device". The position of the formed hole can be checked visually, but since the exact position of the rod provided in the locking device is not known, it is assumed that the rod will be at roughly a position, and the handle of the locking device is turned. If it does not match exactly, not only the position of the variable door cannot be fixed, but also the end of the rod is moved with the rod in contact with the surface of the door frame to match the exact position of the rod and the hole. There was a problem that the surface of the door frame is damaged because the door scratches the surface of the door frame.

The present invention was conceived to solve the above problems, and an object of the present invention is to fix the position of the window in a state where the window is not wide open but only open by a certain width, and further open the window opened by a certain width from the outside. By not allowing or closing the window, it is possible to open and fix the window by a certain width when going out and ventilate even if you go out and block intrusion from outsiders, and even if the window is opened by a certain width, a safety accident in which children, etc. fall. It is to provide a safety lock of the window for ventilation and fall prevention, which can prevent.
