Abstract
An improved slat assembly and curtain for a rolling door assembly employing the improved slat are provided. The slat assembly has a primary slat with a lower bead having a downwardly facing cavity which is used to retain an elastomeric sealing strip which seals the space between adjacent interlocked slats in the curtain. The slat assembly may be provided with a backer slat and material filling a void between the primary slat and backer slat to improve the thermal insulation and/or acoustical insulation and absorption properties of the slat assembly and curtain.
Claims36
A slat assembly for use in a curtain of interlocking slats in a rolling door assembly comprising:
- a primary slat, said primary slat further comprising;
- a web portion having a longitudinal extent, an outer surface, an inner surface, an upper edge and a lower edge;
- an integral upper bead disposed inwardly of said outer surface of said web, said upper bead being joined to said web at said upper edge thereof along the entire longitudinal extent of the web, said upper bead having an upper curved portion;
- and
- an integral lower bead disposed inwardly of said outer surface of said web, said lower bead being joined to said web at said lower edge thereof along the entire longitudinal extent thereof, said lower bead having a curved portion, said curved portion forming a downwardly opening cavity extending along said longitudinal extent of said web;
- wherein an upper surface of said curved portion of said lower bead is shaped to corresponding geometry to an inner surface of said curved portion of said upper bead,
- wherein said upper curved portion of said upper bead is so constructed and arranged to pivotably engage said upper surface of a lower bead of a first adjacent slat to be disposed above said primary slat when said curtain is constructed, and said upper surface of said lower bead is so constructed and arranged to be pivotably engaged within an upper bead of a second adjacent slat to be disposed below said primary slat when said curtain is constructed;
- and
- wherein said slat assembly further comprises seal means for sealing a space between a lower extent of said primary slat and an upper extent of said second adjacent slat to be disposed below said slat assembly, said seal means being retained in said downwardly opening cavity of said lower bead.
A curtain for use in a rolling door assembly comprising:
- a plurality of pivotably engaged slat assemblies, each of said plurality of slat assemblies further comprising:
- a primary slat comprising a web portion having an outer surface, an inner surface, an upper edge, and a lower edge, said slat having a longitudinal extent,
- an integral upper bead disposed inwardly of said outer surface of said web, said upper bead being joined to said web at an upper edge thereof along said longitudinal extent of said web;
- and
- an integral lower bead disposed inwardly of said outer surface of said web, said lower bead being joined to said web at said lower edge thereof along said longitudinal extent of said web, said lower bead having a curved portion forming a downwardly opening cavity extending along said longitudinal extent of said web;
- wherein said upper bead of each of said plurality of slats has a curved portion having an inner surface pivotably engaging and corresponding in geometry to an upper surface of a lower bead of an adjacent one of said plurality of slats disposed immediately thereabove in said curtain;
- and wherein said upper bead of each of said slats overlaps a lower bead of a slat disposed immediately thereabove in an interlocking manner;
- and
- wherein each of said plurality of slat assemblies further comprises seal means for sealing a longitudinally extending space between adjacent primary slats on an outer side of said curtain, said seal means being retained in said downwardly opening cavity of said lower bead.
