THIS IS NOT THE STRUCTURE OF THE TRIPLE-SASH WINDOWS

摘要

PURPOSE: A structure of a triple-sash window without a window frame is provided to widen a view and to reduce manufacturing costs because a window frame is not required. CONSTITUTION: A structure of a triple-sash window without a window frame comprises an upper frame(20), a frameless window frame(30), and a frameless window unit(40). An upper insertion groove(21) is formed in the upper frame. The upper frame is coupled to one end of a window frame(200). Window glass grooves(32), upper window glass grooves(33), and lower window glass grooves(35) are formed in the frameless window frame. The frameless window unit has a frameless window glass inserted into the upper and lower window glass grooves.
