A RETRACTABLE SCREEN ASSEMBLY
Disclosed herein is a screen retraction mechanism for a retractable screen assembly (10). The screen retraction mechanism comprises a roller housing (14). The screen 5 retraction mechanism comprises a roller (200) spinnably mounted within the roller housing (14) and for rolling a screen material sheet (32) thereon. The screen retraction mechanism comprises a torsion spring (202) coupled to the roller (200) for rotationally biasing the roller (200). The screen retraction mechanism (10) comprises a tension adjuster (206) coupled to an end of the torsion spring (202) and configured to move in 10 and out of engagement with the roller housing (14), wherein the tension adjuster (206) is spinnable to selectively tension the torsion spring (202) when out of engagement with the roller housing (14).
