Abstract
A lockable corner bracket includes a lockable encapsulated axle pulley which houses one end of a length of cord, with the free end secured to a side bracket. A cord locking mechanism is used to lock the encapsulated axle pulley and prevent unwinding of the cord, or loss of tension, during transport and installation to facilitate do-it-yourself installation. The axle pulley is further configured with a central slot to allow frontal insertion of a roller tube. The corner bracket may be used with a manual roller screen including roller tubes fitted with spring assist systems to facilitate winding and unwinding of the screen, or with roller tubes fitted with a tubular motor to drive rotation of the roller tube.

A corner bracket and side frame member assembly for a retractable screen system, comprising
- a corner bracket comprising:
- an axle pulley comprising a roller tube support structure located on an external side of the axle pulley wherein the roller tube support structure defines a slot formed from a slot opening and at least one receiving cavity opposite the slot opening such that in use a roller tube is inserted into the slot and the at least one receiving cavity receives at least one locking projection located on an end surface of the roller tube;
- a locking mechanism for locking the pulley;
- a side frame member wherein the corner bracket is connected to or formed at a first end of the side frame member, the side frame member comprising
- a cord tensioning system housed in the side frame member and comprising a plurality of pulleys and a cord tension adjustment arrangement that defines a cord circuit wherein in use the cord tension adjustment arrangement adjusts the tension in the cord as a screen is wound and unwound from the roller tube;
