Battery operated projection screen with spring assisted roller and replaceable fascia

Abstract

A casing for a projection screen and a motorized projection screen system and method for controlling the same are disclosed herein. The casing includes a fascia and endcaps which are affixed to the casing spine without the use of tools thereby providing easy access to the working components housed within the casing and providing flexibility to the consumer in the appearance of the casing. The motorized projection screen system includes a roller having a projection screen attached thereto and a reversible motor operatively connected to the roller such that rotation of the motor causes the roller to rotate and the projection screen to be raised or lowered. The system also includes a biasing mechanism operatively connected to the roller such that rotation of the roller to lower the projection screen biases the roller toward rotation in the opposite direction. The biasing mechanism reduces the power requirements of the reversible motor of the system as it assists in lifting the weight of the projection screen. Furthermore, in one embodiment, the motor utilized is a DC motor and the system includes a DC power supply thereby providing a portable system and eliminating the requirement to connect the system to an external power supply.
