<p>The invention relates to multi-functional window units. The sash (200(a,b)) can be sledded and pivoted by using sliding roller mechanism (260(a,b)), in which the window frame assembly (100) comprises a pair of horizontal frame (112(a,b)) and a pair of vertical frame (131(a,b)). Sash assembly which fixing the glass comprises a pair of sash frame (208(a,b)) cooperated the horizontal frame and a pair of side frame (206(a,b)) cooperated the vertical frame. Each horizontal frame has a cavum (118(a,b)) with opening. Guild rail (124(a,b)) for sliding is on the bottom frame (116(a,b)). A pair of assistant guild rail (126(a,b)) is on both side frame (114(a,b)) respectively. On the sliding roller mechanism sliding along the cavum distribute multi wheels (280), which cooperated with the guild rail and the assistant guild rail. A pin (262) is fixed on the sliding roller mechanism, in one of said frame, for rotating the window frame assembly. The window unite can be rotated outwards at discretion angle on arbitrarily position in its sliding path by a link (342).</p> |
