Abstract: A removable security structure interposed between two window configurations is comprised of interconnecting horizontal and vertical members. One or more vertical members engages a gear junction of each horizontal member such that upon rotation of the vertical member, the horizontal member telescopically collapses. The reduction of length of each horizontal member disengages each horizontal member from a frame outlining the opening. The rotation of the vertical members also frees the upper portion of the vertical members of the security structure. With the upper and side portions of the security structure disengaged from the frame, the security structure can be rotated and removed from the opening allowing egress.
