Patent

CA 2038862

A rolling door assembly includes a flexible curtain having an inner end, an outer end and side edges. The inner end of this curtain is mounted to a rotatable curtain roll. The assembly includes a sprocket mounted on the curtain roll and a continuous chain loop that extends around this sprocket and is connected to a motor drive to form a curtain winding and unwinding mechanism. Two drive loop members are in operable engagement with the curtain roll for purposes of loop travel during rotation of the roll. The bottom end of the curtain is secured to the two drive members so that the bottom end and the drive loop members travel together. There are also two adjusting mechanisms connected between the bottom end of the curtain and the two loop members to accommodate a difference in speed of travel between the loop members and the bottom end of the curtain, the latter moving at a variable speed as the curtain is wound up or unwound.
