Description

OPEN-AND-CLOSE DISPLAY FOR SLIDING WINDOW {APPARATUS FOR LOCKING OF AUTOMATIC OPENED AND OPEN-AND-CLOSE DISPLAY FOR SLIDING WINDOW}

The present invention relates to an opening/closing display and an automatic opening locking device for sliding windows, and more particularly, locking a window in which a housing having a handle having a driving rotation shaft, a central rotating member, a locking member, and a lower auxiliary rotating member is installed. The locking member is easily opened from the window frame in which the release member is installed, and the window is completely locked to the window frame, and the locking member is provided with a rotating member connected to the locking member, an opening/closing indicator, and an opening/closing indicator hole to lock and open the locking member. It relates to an opening/closing display and an automatic opening locking device for a sliding window to be displayed on the provided outer cover.

Various windows are provided inside and outside the building for the purpose of controlling access and lighting.

At this time, the window may be divided into a sliding type, an opening type, or a fixed type according to the opening and closing method, and the double sliding type mainly forms a medium-large window installed in a living room and a veranda of a house.

Such a sliding window is opened and closed by sliding in the transverse direction as the roller at the bottom of the window rotates in the rail of the window frame when pushing or pulling to one side while holding the handle provided on the window.

On the other hand, in the case of recent medium-sized sliding windows, thicker glass or double-layered glass is applied to the window frame than before in order to improve the insulation performance, so the load of the window frame is significant, as well as the window and window frame to improve noise and outdoor air inflow blocking performance. Since the airtight means is applied between the window and the airtight means, it is not easy to slide the window and the door by pushing or pulling the handle while holding the handle, and there is a problem with the inconvenience of opening the window.

In addition, there is a problem in that the window is not kept completely tightly locked to the window frame, or the security effect is inferior because the window is not properly locked to the window frame when the window is locked in the window frame.

In addition, there is a problem in that the locking and unlocking of the windows and the windows frames are not visually confirmed by the user in the window opening locking device installed on the windows, so that the locking and unlocking of the windows and doors are incomplete.
