Patent CA-2436381-A1 (CA)
Title: Roll-up door curtain and guides
Inventor: THOMPSON DAVID S
IPC: E06B9/58
Filed: 2003-08-01
Abstract: A roll up door assembly for covering a door space comprising a rubber sheet having vertical side edge portions with a front lock strip secured to the front surface and a rear lock strip secured to the rear surface of each vertical side edge. The front and rear locking strips are staggered with respect to each other in the transverse direction of these strips. The sheet is coilable on a barrel mounted above the door. The staggered orientation of the lock strips assists in the tracking of the sheet during coiling on the barrel. A pair of vertically extending door guides each define a vertical slot oriented and sized to accept a respective vertical side edge portion for guided vertical movement therein. Each door guide assembly has a windbar attached thereto, positioned to narrow the opening of the slot such the narrowed opening has a smaller width than the total thickness of each side edge portion of the sheet. Tension spring assemblies bias the windbar with sufficient force to normally hold the vertical side edge portion within the slot while permitting the side edge portion to be released from the slot through the opening upon an impact to the sheet.
