INVENTOR. RICHARD N. ANDERSON ATTORNEYS WINDOW STRUCTURE CROSS-REFERENCE TO RELATED APPLICATIONS The invention is a storm sash for piggyback installation on prime window sash having a frame with an exterior surface and a prime glazing panel secured within the frame in spaced relation to one surface of the frame, such as the prime sash disclosed in applicants US. Pat. No. 3,643,377, issued Feb. 22, 1972 and applicants co-pending application Ser. No. 36,303, filed June 22, l970.

BACKGROUND OF THE INVENTION l. Field of the Invention The invention relates to window structures and refers more specifically to a storm sash and means for securing the storm sash to a prime window sash, which storm sash and securing means are particularly simple in construction, economical to manufacture, and efficient in use.

2. Description of the Prior Art In the past, storm windows have usually included relatively massive frames which have been rigidly secured to a building over prime window structure. Such prior storm windows have entirely separate sash members including sash frames and sash glazing panels and have, therefore, been relatively expensive and often difficult to install over prime window structure.

SUMMARY OF THE INVENTION It is the purpose of the present invention to provide a storm sash which may be conveniently installed in a piggyback fashion on a prime window sash to provide an insulating air space between the storm sash glazing panel and the prime sash glazing panel. For this purpose a unique dual durometer plastic strip is disclosed operable to securely receive the periphery of a storm sash glazing panel, space the storm sash from a prime window glazing panel, and seal the storm sash glazing panel within the frame of the prime window sash.

The storm sash is secured to the prime window sash by an extension on the dual durometer plastic peripheral strip cross section in one modification of the invention. A plurality of modifications of a retainer clip are also disclosed for holding the storm sash in assembly with the prime window sash.

DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown best in FIG. 1, the storm sash 10 of the invention is applied to prime window structure 12. The lower exterior right hand corner of the prime window structure 12 illustrated includes a sill 14, a jamb 16, a prime sash 18 having a prime glazing panel 20 secured therein by glazing strip 22, and a trim molding 24. It will be particularly noted that the outer surface 26 of the prime window structure 12 is in spaced relation to the prime glazing panel 20.

The storm sash 10 of the invention includes the storm glazing panel 28, the peripheral plastic strip 30 and the retainer clip 32.

The peripheral strip 30 as best shown in FIG. 3 is a dual durometer hardness plastic extrusion and includes a relatively hard U-shaped cross section portion 34 for receiving the periphery of the storm sash glazing panel 28 as shown in FIG. 2. Relatively soft longitudinally extending barbs project inwardly and toward the connecting portion of the U-shaped cross section portion from both legs thereof for securing the strip to the storm glazing panel 28. A relatively hard longitudinally extending spacing projection 38 is provided on the cross section of the strip 30 projecting substantially in the plane of the connecting part of the U-shaped cross section portion of the strip toward the prime glazing panel 20 with the storm sash 10 in assembly, as shown in FIG. 2. Projection 38 serves to space the storm glazing panel 28 from the prime glazing panel 20.

In addition, the strip 30 includes a longitudinally extending relatively soft sealing flange 40 projecting downwardly from the U-shaped cross section portion of the strip 30 before assembly of the storm sash 10, as shown in FIG. 3. The flange 40 is arcuately deformed as shown best in FIG. 2 on assembly of the storm sash in a prime sash 12 to provide a seal between the storm sash and prime sash.

The retainer clips 32 are generally L shaped and include a portion 42 adapted to engage the plastic strip 30 of a storm sash in installation, as shown best in FIG. 2. The portion 44 of the retainer clip 32 includes an opening 46 therein through which a screw or the like is inserted to secure the retainer clip 32 in an adjusted position on the prime sash l2 with the storm sash 10 in assembly as shown best in FIGS. 1 and 2. As illustrated, the retainer clip 32 is of variable thickness providing an offset 48 preventing interference with the glazing member 22 of the prime window structure 12 and the plastic strip 30 of the storm sash 10.

In use, the glazing strip 30 is first positioned around the periphery of the storm glazing panel and the assembled storm sash 10 is positioned within the frame 26 of the prime sash 18. The retaining clips 32 are then positioned and secured to the prime sash 18. The stonn sash 10 is thus installed in a piggyback fashion on the prime sash I8 to provide excellent insulation at a minimum cost with substantially no maintenance problems. In addition, the original prime window structure is substantially unchanged in appearance.

In the prime window structure 60 illustrated in FIG. 5, a prime sash 62 is pivotally supported by pivot means 64 in frame 66. A weather seal 68 is provided between the periphery of the prime sash 62 and the prime window structure frame 66. A prime glazing panel 70 is held in the prime sash 62 by means of the glazing strip 72.

The storm sash 74 includes the storm glazing panel 76 and the dual durometer plastic strip 78. The plastic strip is applied to the storm glazing panel 76 around the periphery thereof and the assembled storm glazing panel and plastic strip are secured in the prime window structure 60 in piggyback fashion.

As shown better in FIG. 6, the plastic strip 78 includes the relatively hard U-shaped cross section portion 80 into which the edge of the storm glazing panel 76 is inserted and the relatively soft barb portions 82 for retaining the storm glazing panel 76 and the plastic strip 78 in assembly. The plastic strip 78 further includes the relatively soft sealing flange 84 for sealing between the storm sash 74 and the glazing strip 72, as shown best in FIG. 5.

The plastic strip 78 further includes the relatively hard cross section portion 86 extending generally arcuately from the bottom of the U-shaped portion of the cross section of the plastic strip terminating in an L- shaped cross section part 88 adapted to fit within the recess 90 in the prime sash and around bead 92 as shown in FIG. 5 to retain the storm sash 74 in assembly with the prime sash 62 without separate retainer clips.

The prime window structure illustrated in FIG. 7 is the same as that of FIG. 6 so that the same reference numerals are used to designate the same portions of the prime window structure. However, the storm sash 94 illustrated in FIG. 7 besides the glazing panel 96 includes a modified dual durometer hardness plastic strip 98 which is better shown in FIG. 8 in perspective. A retaining clip 100 better shown in FIG. 9 is used for retaining the assembled glazing panel 96 and plastic strip 98 on the prime window structure.

The pla ti strip again includes the rigid U-shaped cross section portion 102 and the relatively flexible barb portions 104 for receiving and holding the periphcry of the glazing panel 96 respectively. The sealing flange 106 is again provided to seal between the storm sash 94 and the glazing strip 72 and is of softer plastic than the relatively hard U-shaped portion 102 of the strip 98.

The retaining clip 100 is substantially S-shaped in cross section and is provided with the longitudinally extending foot portion 108 and the heel portion 110. In assembly, the foot portion 108 of the clip 100 is received in the recess in the prime sash jamb with the head 92 between the foot portion I08 and the heel portion 112 of the clip 100, as shown in FIG. 7. The retaining clip which is of relatively rigid plastic may be of any desired length to provide the required holding force on the storm sash structure 94.

The prime window structure and the glazing panel and plastic strip of the storm sash jamb section illustrated in FIG. 10 are the same as those illustrated in FIG. 7 and have, therefore, been indicated by the same reference numerals. However, the retaining clip 114 as illustrated in FIG. 11 includes a pivot head 116, a transition portion 118, a retaining portion and a camming portion 122. In use, the pivot head 116 of the retaining clip 114 is positioned in the recess 90 in the prime sash jamb and the retainer portion 120 together with the transition portion 118 is rotated about the pivot head 126 until the cam portion 122 snaps over the bead 92 of the prime sash jamb to lock the storm sash in position on the prime sash.

Similarly, the prime window structure and the storm glazing panels and plastic strips illustrated in the window jamb sections illustrated in FIGS. 12 and 14 are the same as those illustrated in FIGS. 7 and 10 and have, therefore, been given the same reference numerals. However, the retaining clip illustrated in FIG. 13 has been used to mount the storm glazing panel and plastic strip in piggyback fashion on' the prime window sash as shown in FIG. 12, while the retaining clip illustrated in FIG. 15 has been used to secure the storm glazing panel and peripheral plastic strip in the prime window sash illustrated in FIG. 14.

The retaining clip 124 illustrated in FIG. 13 includes the tabs 126 and 128 at the opposite ends thereof, the body portion 130 located centrally thereof and in spaced relation to the tabs 126 and 128 having the toe portion 132 at the end thereof. A camming portion 134 is provided centrally of the body portion of the retaining clip 124.

In assembly as shown in FIG. 12, the relatively thin tabs 126 and 128 are inserted between the U-shaped portion 102 of the plastic strip 98 and the storm glazing panel 96 on movement of the clip 124 to cam the camming portion 134 of the clip over the bead I36 especially provided on the particular plastic strip 98 illustrated in FIG. 12 until the toe portion 132 of the clip snaps over the bead 92 on the sash to lock the clip in position as shown in FIG. 12.

With such construction, the camming portion 134 tends to apply pressure to hold the toe portion 132 against head 92 when removal of the clip 124 is attempted. Physical bending of the plastic clip 124 is thus necessary to remove the storm sash 74.

The retaining clip 126 includes the elongated bar portion 140 having longitudinal groove 152 therein terminating in the end portions 142 and 144 extending at right angles thereto and the foot portion 146 extending in the same direction as the end portions 142 and 144 of the bar portion. The retaining portion 148 of retaining clip 126 extends at right angles to the foot portion and includes the bead 150 thereon, as shown in FIG. 15.

In use, the foot portion 146 and the end portions 142 and 144 of the bar portion 140 and the bar portion 140 is inserted in the recess 90 in the prime sash 62, as shown best in FIG. 14 with bead 92 in groove 52. The elongated bar portion 140 permits flexing of the clip 126 in the recess 90 to engage or disengage the clip 140 from the bead 92 to remove the clip 126 from the recess 90 when it is desired to remove the clip. Thus, the clip 126 has the particular advantage of self storing in the recess 90.

Furthermore, with the clip 126 at one extreme of the movement thereof in the recess 90, the storm sash '74 may be removed from the prime sash 62 without removing the clips 126. Loss of the clips on inserting and removing the storm sash when the clips 126 are used is therefore not likely.
