Roll bar device for retractable awnings

摘要

A roll bar adapted for attachment along one edge of an awning sheet so that the awning sheet can be retracted around the roll bar or extended away from the roll bar includes a generally cylindrical tubular element having longitudinally extending indentations therein with a generally circular groove in the indentation which is partially defined by a pair of upstanding lips having a space therebetween into which the awning sheet can be inserted. The edge of the awning sheet inserted into the groove has a sleeve formed therein which receives an elongated rod which is larger in diameter than the spacing between the lips so that the rod cooperates with the lips in retaining the edge of the awning sheet in the roll bar. The lips are designed such that the ends thereof can be flared outwardly to facilitate insertion of the awning sheet into the groove without snagging and possibly damaging the awning sheet material. The roll bar further includes a plurality of screw-receiving openings in opposite ends thereof to facilitate attachment of an end cap thereto. The end cap has a plurality of spaced dogs around its perimeter and the angular relationship of the dogs to the roll bar is adjustable by variable utilization of the screw-receiving openings in the end of the roll bar with screw-type fasteners extending through the end cap and into the roll bar.
