Insulated roll-up door

Claim 2

A roll-up door comprising: a plurality of elongated adjoining slats; hinge means for coupling said adjoining slats together for relative movement of said slats between a vertical co-planar arrangement when the door is closed, and an arcuate arrangement when the door is being rolled up; each of said slats including a U-shaped elongated channel having a web portion interconnecting inwardly directed opposed flange portions, said web portions of said slats cumulatively defining a front face of the door; distal ends of said opposed flange portions of each slat terminating in forwardly directed arcuately curved first and second segments to define said hinge means; said first segment on each slat having a curvature substantially concentric with and smaller than a curvature of said second segment on each respective slat; said smaller first segment defining an elongated hinge pin for insertion into a hinge barrel of an adjoining slat on one side thereof; said larger second segment defining an elongated hinge barrel for receiving a hinge pin of an adjoining slat on an opposite side thereof; and insertable and removable elongated insulation members being co-extensively disposed along each slat with each insulation member being positioned between said opposed flange portions of each respective slat; each of said insulation members having a thickness from front to rear thereof less than depth of each of said U-shaped slat channels correspondingly from front to rear thereof so that said front of each of said insulation members is in a rearwardly spaced apart relationship to said web portion of each of said slats;

Claim 3

first and second support means on opposing sides of each of said insulation members for suspending each of said insulation members in said rearwardly spaced apart relationship to each of said slat web portions to provide an air space therebetween for additional insulation, said air space extending from one flange portion of each of said slats to the other flange portion of each of said slats; said first support means including an elongated arcuate hook extending from a rear edge on one side of said insulation member for latching around an exterior of said elongated hinge barrel on each respective slat; said second support means including an elongated lip resiliently projecting from said rear edge on the opposite side of said insulation member; said elongated lip being in continuous engagement on an elongated hook of an adjoining insulation member for suspending said insulation member above said slat web portion of its respective slat; said elongated hook of each insulation member securing and suspending said insulation member relative to its respective slat; foot means for wedging against said one flange portion beneath said elongated hinge pin on each respective slat to retain said insulation members in its suspended position along said respective slats; said foot means including an elongated foot projecting from a front edge on said opposite side of each insulation member; said opposite side of each insulation member being provided with recess means between said lip and said foot for accommodating said elongated hinge barrel and elongated hook of its associated adjoining slat; and said recess means including an arcuate recess having a curvature extending from said foot to be concentric with an arc of rotation of said adjoining slats.

Claim 4

first and second support means on opposing sides of each of said insulation members for suspending each of said insulation members in said rearwardly spaced apart relationship to each of said slat web portions to provide an air space therebetween for additional insulation, said air space extending from one flange portion of each of said slats to the other flange portion of each of said slats; said first support means including an elongated arcuate hook extending from a rear edge on one side of said insulation member for latching around an exterior of said elongated hinge barrel on each respective slat; said second support means including an elongated lip resiliently projecting from said rear edge on the opposite side of said insulation member; said elongated lip being in continuous engagement on an elongated hook of an adjoining insulation member for suspending said insulation member above said slat web portion of its respective slat; said elongated hook of each insulation member securing and suspending said insulation member relative to its respective slat; foot means for wedging against said one flange portion beneath said elongated hinge pin on each respective slat to retain said insulation members in its suspended position along said respective slats; said foot means including an elongated foot projecting from a front edge on said opposite side of each insulation member; said opposite side of each insulation member being provided with recess means between said lip and said foot for accommodating said elongated hinge barrel and elongated hook of its associated adjoining slat; and said recess means including an arcuate recess having a curvature extending from said foot to be concentric with an arc of rotation of said adjoining slats.

Claim 5

A roll-up door as in claim 1, wherein said insulation members include hollow sleeves for receiving insulation material therein.

Claim 6

A roll-up door as in claim 1, wherein said curved first and second segments extend only partially across said flange portions toward said web portion so that said first and second segments are spaced from said web portion.

Claim 7

A roll-up door as in claim 1, wherein said arcuate recess is greater than required to provide an air space for additional insulation.

Claim 8

A roll-up door as in claim 1, wherein each insulation member includes an elongated hollow sleeve having a substantially rectangular cross sectional configuration defined by front and back walls interconnected by opposing side walls and said elongated hook extending from a back edge of the other side wall.

Claim 9

A roll-up door as in claim 5, and further comprising an elongated intermediate wall extending between said front and back walls of said insulation member for additional support.

Claim 10

A roll-up door as in claim 1, wherein each insulation member is integrally molded of a plastic material.

Claim 11

A roll-up door as in claim 1, and comprising stop members connected to lateral ends of said slats to close off said slats for maintaining said insulation members along said slats.

Claim 12

A roll-up door as in claim 8, wherein said stop members includes two legs to provide an L-shaped configuration, one leg being secured onto said slat and the other leg closing off the lateral end of said slat.

Claim 13

A roll-up door as in claim 8, wherein each of said stop members is formed from a flat construction, one part of said stop member being secured onto a web portion of said slat and another part thereof being bent substantially perpendicular to said one part after securement to said web portion to close off the lateral end of said slat.

Claim 14

A roll up door as in claim 1, wherein associated portions of said hinge means are integral with each of said slats.
