Sealing strip

Inventors: Hast, Gunnar;

Attorney, Agent or Firm: Pollock, Vande Sande & Priddy
A sealing strip, especially for doors and windows, comprising a porous, resilient core and an outer covering which encloses the core and is circumferentially prolongated to form an elongated mounting flange extending lengthwise along the strip. A gas-proof, flexible foil material is inserted between the core and the covering and is likewise circumferentially prolongated. The foil material and the outer covering are bound to each other only in the region of the mounting flange so as to permit a certain sliding movement between those portions of the foil material and the outer covering, which enclose the core, when the strip is compressed or resiliently expanded. |

DETAILED DESCRIPTION I claim: 1.
A sealing strip for doors, windows and the like, comprising, in combination (a) an elongated, resilient, porous core of a synthetic foam material; (b) a flexible covering enclosing said core and consisting of an outer layer of textile material an an inner layer of a gas-proof, flexible foil material; (c) said outer and inner layers both being prolongated circumferentially so as to jointly form an elongated mounting flange and being bound together only in the region of said mounting flange; (d) the thickness of the outer and inner layers being dimensioned so as to permit resilient expansion of the core without substantial resistance from said layers while permitting sliding movement between those portions of said layers which enclose the core.
2.
A sealing strip according to claim 1, wherein the foil material is dark colored so as to protect the core from sunlight.
3.
A sealing strip according to claim 1, wherein the thickness of said inner layer is 0.
05 to 0.
08 mm.
Description:
BACKGROUND OF THE INVENTION The invention relates to a sealing strip, especially for doors or windows, comprising an outer covering, e.
g.
, of textile material, and enclosed therein a resilient core of porous material, such as foamed plastic, textile fibres, foamed rubber or the like, the outer covering being circumferentially prolongated to form an elongated mounting flange extending lengthwise along the strip.
Previously known sealing strips with a porous resilient core, usually of foamed plastic, have, in contrast to strips of extruded solid plastic, a good ability to recover, i.
e.
, to resume their original shape.
However, the strips of foamed plastic (with or without an outer covering of textile material) available on the market all have the disadvantage of serving as a soot and dust filter rather than a sealing device.
Furthermore, the foamed plastic rapidly deteriorates by the influence of the soot and dust particles being gathered in the pores of the foamed plastic material
