Patent ID: 8661734

Claim:
A window assembly comprising a frame in which are received sliding and security members, the security member having a ventilating part received within a first sub-frame and a non-ventilating part received within a second sub-frame, with the sliding member being slidably moveable over the security member between a first position in which air may pass through the ventilating part, so as to ventilate the room in which the window assembly is located, and a second position in which no such ventilation can occur, wherein the ventilating part is received within a pair of opposed inwardly facing gaps in the first sub-frame which both open towards each other out onto a first common plane, the non-ventilating part is received within a pair of opposed inwardly facing gaps in the second sub-frame which both open towards each other out onto a second common plane, and said inwardly facing gaps in the first and second sub-frames are of substantially the same width; wherein said inwardly facing gaps are each defined by at least a bottom and two opposed spaced apart legs, wherein the opposed spaced apart legs forming each gap extend approximately the same distance from the bottom of the gap, and wherein the opposed spaced apart legs are substantially parallel to each other and also to the common plane onto which the gap opens; and a concealing clip extending between one of the opposed legs defining each inwardly facing gap in the first sub-frame and the ventilating part.
