Abstract
A screen retraction mechanism for a retractable screen assembly, the screen retraction mechanism comprising: a roller housing; a roller spinably mounted within the roller housing and for rolling a screen material sheet thereon; a torsion spring coupled to the roller for rotationally biasing the roller; and a tension adjuster coupled to an end of the torsion spring and configured to move in and out of engagement with the roller housing, wherein the tension adjuster is spinnable to selectably tension the torsion spring when out of engagement with the roller housing.
Claims19
A screen retraction mechanism for a retractable screen assembly, the screen retraction mechanism comprising:
- a roller housing;
- a roller spinably mounted within the roller housing and for rolling a screen material sheet thereon;
- a torsion spring coupled to the roller for rotationally biasing the roller;
- a rotary damper assembly in rotary engagement with the roller;
- and
- a tension adjuster coupled to an end of the torsion spring and configured to move in and out of engagement with the roller housing, wherein the tension adjuster is spinnable to selectably tension the torsion spring when out of engagement with the roller housing;
- wherein the tension adjuster and the housing are cooperatively configured for dis engageable threaded engagement.
A kit of parts that can be assembled into a screen retraction mechanism, the kit comprising:
- a roller housing;
- a roller for spinably mounting within the roller housing and for rolling screen material sheet thereon;
- a torsion spring for coupling to the roller for rotationally biasing the roller;
- a tension adjuster for coupled to an end of the torsion spring and configured to move in and out of engagement with the roller housing, wherein the tension adjuster is for spinning to selectably tension in the torsion spring when out of engagement with the roller housing, wherein the tension adjuster and the housing are cooperatively configured for dis engageable threaded engagement;
- and a rotary damper assembly for rotary engagement with the roller.
A method of assembling a screen retraction mechanism, the method comprising the steps of:
- attaching a sheet of screen material to a roller for rolling the sheet of screen material thereon;
- spinnably mounting the roller within a roller housing;
- coupling the roller to a torsion spring;
- coupling a tension adjuster to the torsion spring;
- unthreading the tension adjuster from the housing;
- operating the tension adjuster to selectively tension the torsion spring;
- coupling the roller to a rotary damper assembly;
- and engaging the tension adjuster to the roller housing;
- threading the tension adjust with the housing.
