Sliding window with improved air tightness

Abstract

The present invention relates to a sliding window 100 with improved air tightness including a window frame 110 having a plurality of rails 111 disposed along the longitudinal direction thereof, at least one pair of window sashes 120 slidingly coupled to the rails 111, and wheel assemblies 200 rotatably mounted on facing surfaces 123 of the window sashes 120 laid on each other when the window sashes 120 are closed, whereby at the moment when the wheel assemblies 200 are rolling-contacted with the facing surfaces 123 of the window sashes 120 upon the closing manipulation of the window sashes 120, the window sashes 120 are horizontally moved in the direction perpendicular to the sliding direction thereof.

Description

technical field [0001] The present invention relates to a sliding window, more specifically, to a sliding window with improved airtightness, which can make the sash closely contact the window frame when the sash is closed and manipulated to achieve high airtightness. Background technique [0002] Generally, windows or doors are installed in open parts to seal off the interior of a building from the exterior. Meanwhile, a window frame supporting a window or a door is classified into a wooden window frame and a metal window frame according to the material used. Recently, door or window frames are made of plastic or synthetic resin such as P.V.C. [0003] In the process of opening or closing a conventional sliding window, if the sash is slid in the closing direction while the sash handle is held by the user, the roller installed on the bottom edge portion of the sash rotates along the guide rail formed on the window frame, so that The sash is moved close to its opposite frame...

AI Technical Summary

Problems solved by technology

[0004] However, in the case of a conventional sliding window having a window frame and sashes, the mohair is worn due to repeated use over a long period of time, resulting in deterioration of the airtight performance

Therefore, cold or hot air from the outside may be introduced through the gap between the sash and the top and bottom edge portions of the window frame or the gap between the left and right sash adjacent to each other, so that the airtight state cannot be maintained.

This results in energy consumption and the introduction of foreign matter such as dust into the interior from the outside
