BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a window structure, and more particularly, to a window structure that can prevent the flow of outside or inside air through a gap between a chassis assembly and a window assembly, It relates to the window structure.

Generally, a window structure is a structure including a chassis assembly embedded in an open formed portion of a building wall surface and a window assembly openably and closably installed in the chassis assembly.

Among the window structures, the chassis assembly includes a pair of horizontal side window frame frames forming upper and lower window frames, and a pair of vertical window frame frames forming left and right window frames.

In addition, the window assembly of the window structure includes a window and a window frame for restricting the window.

Meanwhile, although the above-described window structure has a variety of structures, a sliding window type window structure that opens and closes a window with a sliding door structure is mainly used. Such a sliding window type window structure is usually formed by a pair of window assemblies And is installed in the chassis assembly to be opened and closed in a sliding manner.

At this time, the guide rails are protruded from the opposite sides of the two horizontal side window frame frames constituting the chassis assembly, so that the two window assemblies are guided by the guide rails and can perform accurate sliding movement.

However, in the case of the above-described sliding door type window structure, since the two window assemblies are slidably installed while being spaced apart from each other, the outside air flows into the space between the chassis assembly and the window assembly or between the window assemblies, There is a disadvantage that the heat insulating property is low.
