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.
