Storm window framing, including a tape frame having a tape-receiving channel defined by spaced, parallel inner and outer ribs and one surface of a connecting web, a pane-receiving channel and a seat boss, the seat boss including a pair of spaced jaws defining between them a seat boss channel, keyhole-shaped in transverse section and with an outwardly opening, outwardly flaring mouth, and a glazing frame having a tenon strip with a head and neck adapted to fit in the keyhole-shaped seat boss channel and a root flared complementarily to and adapted to fill the mouth of the tape frame seat boss channel when the head and neck are fully seated, and, integral with and cantilevered from the root, a pane biasing leaf strip, extending at an angle toward the pane-receiving channel of the tape frame. Preferably, the full framing includes a sill section, extending along a lower edge of a pane and engaging a window sill. The sill section is preferably a one-piece shape, with a pane-receiving channel, a pane biasing leaf strip extending at an angle toward the pane-receiving channel, and a base, extending from the pane-receiving channel and leaf strip a substantial distance beyond the leaf strip to form a wide, sill-engaging platform.
In a storm window wherein a pane is held in extruded frame members mounted to a window by adhesive, the improvement comprising, along at least two sides of said pane, a tape frame having a pane channel defined in part by an upstanding inner wall and one external surface of a boss at an outer edge of said tape frame, said boss including a pair of spaced jaws defining between them a channel, keyhole shaped in transverse cross section and with an outwardly opening, outwardly flaring mouth;

It has been proposed in the past to provide frost shields for windows and windshields, in which a frame is mounted on a window by means of tape or adhesive, as shown in patents to Hogelund, U.S. Pat. No. 1,777,435, and Walz, U.S. Pat. No. 2,111,343. Extruded plastic moldings for windows have been proposed, as indicated in U.S. Pat. Nos. 3,455,080, Meadows, and Crane, No. 3,363,390, and a combination of the two, in Bero, No. 3,939,620.
One of the objects of this invention is to provide a storm window frame of extruded plastic, which, through at least three sides, is provided with double-faced tape by which the frame can be mounted to an existing window, which is simpler, more economical, and more effective than any of the prior art devices.
Other objects will become apparent to those skilled in the art in the light of the following description and accompanying drawings.
In the drawings, FIG. 1 is a view in front elevation of a window with a storm window frame of this invention in place;
FIG. 2 is a transverse sectional view of a portion of the upper framing before it is placed around a pane, and without the double faced stripping by which it is adhered to the window;
FIG. 3 is a sectional view taken along the line 3--3 of FIG. 1;
Referring now to the drawings for one illustrative embodiment of frame of this invention, reference numeral 1 indicates a window with a frame 2 with a flat inside surface 3 extending entirely around it. A storm window 4 of this invention, with a pane 5 and a frame 6, is mounted on the window frame 2, in such a way as to engage a window sill 7 along its lower edge.
The storm window 6 is made up of side sections 11 and 12, a top section 13 and a sill section 14.
The side sections 11 and 12 and top section 13 can be of identical construction. Each of them is made up of a one-piece tape frame 20 and a one-piece glazing frame 21.
