Polymeric sealing/spring strip and exTrusion method of producing same

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The following is a detailed description of the preferred embodiments of the invention which are presently considered to be the best modes of the invention for a variety of applications.
FIG.
1 shows a cross-section view of a first embodiment type in accordance with the present invention.
FIG.
1 shows sealing/spring strip 1 which comprises polymeric extrudate 2.
Polymeric extrudate 2 has upper surface 3 from which extend extension portions 4 so as to form well 5.
Well 5 is completely filled with silicone rubber 6 so as to expose a meniscus forming resilient surface 7 of silicone rubber.
Sealing/spring strip 1 is employed by fixing it to a first surface 8 which, together with second surface 9 represent two surfaces between which a seal is desired.
Once fixed to first surface 8, the sealing/spring strip may be urged against-second surface 9 so that resilient surface 7 forms a seal against second surface 9.
Sealing/spring strip 1 may be affixed to first surface 8 by any well-known mechanical means such as through the use of nails, screws, bolts, adhesives or any other equivalent mechanical force.
Alternatively and preferably, the sealing/spring strip 1 may be integrally incorporated into the balance of the structure represented by first surface 8 (such as in the form of an integral polymeric piece).
FIG.
6 shows a cross-sections of a sealing/spring strip in accordance with a first embodiment type of the present invention, and featuring a profile adapting the strip for use in a dual pane window assembly.
This embodiment shows that the base portion of the extrudate may be shaped to adapt to any particular application.
In the case of FIG.
6, the profile of the extrudate is adapted to accept and maintain in position two glass panes in a dual pane thermal window assembly, in accordance with known geometries for such assemblies.
Such assemblies may be manufactured in accordance with assembly and production practices known in the art.
FIG.
6 shows base portion shows jamb liner 60 which incorporates base portions 61, each provided with extension portions 62, forming respective wells 63, and adapted to hold silicone rubber bead 64
