High efficiency motorized roller screen and method of operation
First Claim
1. A method of operating a deployable screen system, the steps comprising:
- providing a roller tube;
connecting screen material to the roller tube;
positioning a motor and a controller within the roller tube;
connecting at least one battery with the motor and the controller;
sensing a first tug when the screen material is in a retracted position; and
moving the screen material to a deployed position in response to sensing the first tug;
wherein the roller tube rotates around a pair of non-rotating support shafts extending outwardly from opposing ends of the roller tube.

Abstract
The invention advantageously provides a deployable screen system that includes a roller tube, a motor/controller unit and a power supply unit. The motor/controller unit is disposed within the roller tube, and includes a bearing, rotatably coupled to a support shaft, and a DC gear motor. The output shaft of the DC gear motor is coupled to the support shaft such that the output shaft and the support shaft do not rotate when the support shaft is attached to the mounting bracket. The deployable screen system is operable by tugging, manual movement and wireless control. The DC gear motor is underpowered by a plurality of batteries positioned within the roller tube. In this way a novel, useful and nonobvious deployable screen system is presented.
