摘要

A support rail system for hanging rolling doors has a shaped rail (212) fitted on the outside of the building (13) over the door opening. The rail is made from folded metal strip and comprises a flange for securing to the building and a sloping top (213) and a profile (114) open to the ground with ducts (218, 219) forming the support rails for the rollers. The rollers (216, 217) are shaped to fit into the V-shaped tracks and are fitted to the top edges of the doors (220, 221) by angled connecting supports. The shape of the rail system provides an integral weather support and the doors are simple to hang into the rails.
