embodiment 310

[0028] The weather-strip of the present invention can also be attached to the cover member using an adhesive or through a strip attached to the sealing member that in turn is adhesively attached to the cover member as illustrated in FIG. 6. The embodiment 310 includes a sealing member 312 and an adhesive strip 314 having a backing 316 and a layer of adhesive 318. The embodiment 310 is secured directly to the cover member through the use of the adhesive.

[0029] Another embodiment of the present invention is illustrated in FIG. 4. The embodiment in FIG. 4 includes a sealing member 112 similar to the sealing member illustrated in FIG. 1. The sealing member is attached to an attaching member that has an “L”-shaped cross sectional profile. The attaching member also includes barbs 124 which are positioned in a direction so that the attaching member can be inserted into a kerf (not shown), but resists removal of the attaching member from the kerf once inserted into the kerf. The attaching m...

embodiment 210

[0030] Another embodiment of the present invention is illustrated in FIG. 5. The embodiment 210 includes a sealing member 212 similar to the sealing members discussed with respect to FIGS. 1 and 4. The attaching member 215 includes a leg portion 225 that extends from the cap portion 226 bent in an “L” shaped manner such that the distal end portion 227 is substantially parallel to the cap portion 226. It will be appreciated that the embodiment 210 engages a kerf (not shown) that is located on the surface 90 degrees from the surface from which the sealing portion 212 extends.

Abstract

A weather-strip construction includes a frame member and a cover member and a weather-strip. The cover member mates with the frame member and the weather-strip forms a weather seal between the frame member and the cover member. The weather-strip includes a foamed sealing portion. The weather-strip is secured to either the frame member or the cover member. The foamed sealing portion of the weather-strip provides the weather seal and extends continuously along either the frame member or the cover member depending to which one it is attached and extends along any sharp corners continuously without interruption such that a continuous weather seal is formed between the cover member and the frame member.

Description

CROSS-REFERENCE TO RELATED APPLICATION [0001] This application claims the benefit of U.S. Provisional Application 60 / 602,132 filed on Aug. 17, 2004 for inventor James L. Peterson et al. and entitled ONE PIECE CORNERING WEATHER-STRIP.BACKGROUND OF THE INVENTION [0002] The present invention relates to weather-strips and in particular relates to weather-strips that have a sealing member made from a foamed polymer. [0003] Presently there are several materials being used to make foamed weather-strips for residential windows and doors. These materials produce very satisfactory weather-strips. Such weather-strips have a foamed sealing member and an attaching member that is used to secure the sealing member to the door or window. Typically the attaching member is made of a solid polymer. [0004] One material used for the foamed sealing member in weather-strips is SANTOPRENE®. SANTOPRENE® is an elastomeric thermoplastic rubber which may be foamed to produce extruded cylindrical and other prof...
