A frame particularly for use in a supplemental window which may be installed in an existing window case comprising sections of a linear extrusion forming a rigid body. The elements including a screw receiving channel, a channel adapted to hold sliding pins, a channel adapted to hold a pane and a channel adapted to fasten a compressible gasket to the element. Four such elements fastened together by means of screws form a rigid body surrounding the pane. The outside dimensions of this rigid body are slightly smaller than the inside dimensions of the window case in which it is adapted to be fitted. The rigid body is surrounded by a compressible gasket which is adapted to be compressed against the inside of the window case to form a seal therewith. The sliding pins are adapted to be slid into holes in the window case and to be locked in that position, thus providing a pivotal mounting for the supplemental window. The compressible gasket provides an effective weather and noise seal and holds the supplemental window in an open position when desired. The compressible gasket also compensates for irregularities in the linearity and dimensions of the window cases in which it is adapted to be fitted.
A frame for installation in a rectangular window case having pin receiving means thereon, said frame comprising a substantially planar rigid frame including four linear elements having first surfaces which together form an outer peripheral surface of said rigid frame which is rectangular, pivot pins mounted on said rigid frame, a compressible gasket attached to said linear elements, said compressible gasket being positioned adjacent said outer peripheral surface to provide an outer periphery which circumscribes the outer peripheral surface of said frame so that said gasket is adapted to be compressed between said outer peripheral surface and said window case when the window is closed, said pivot pins being positioned in an axis which is parallel to the plane of said frame and proximate to one side of said frame so that said frame is adapted to be mounted to permit it to be pivoted so that it may be positioned ajar of the window case, said pins being adapted to be positioned in said pin receiving means associated with said window case to permit pivotal movement of said frame about said axis whereby, when the window is open, the frame is held against movement by static frictional forces resulting from compression of portions of the gasket.
In combination with a window and a window case surrounding said window, a storm window comprising a frame within which a window pane is mounted, said frame comprising a rectangular rigid member including four linear elements fixedly positioned at right angles to one another, said elements having first surfaces which together form an outer peripheral surface of said frame, a compressible gasket mounted on said peripheral surface, said gasket being positioned adjacent said outer peripheral surface and being adapted to be compressed between said outer peripheral surface of said frame and said window case, pivot pins mounted on said frame and positioned in an axis which is parallel to the plane of the storm window, said axis being parallel to and proximate to one side of said frame, said pins being positioned in recesses in said window case to permit pivotal movement of said storm window about said axis, whereby when the window is open, the frame is held in position by static frictional forces resulting from compression of portions of the gasket.
