Abstract
Abstract A closure for a wall opening, such as a window, in which the closure is in the form of a rolling shield adapted to be wound up on a shaft. The shaft is rotatably mounted in a box and the box supports guides for the said edges of the shield so that the entire closure arrangement forms a unit adapted for being mounted on the wall containing the opening to be closed thereby in a simple manner.

Claim 1
Independent Claim
148 words
In combination on a rolling closure for a wall opening: a box having end walls, a shaft extending along said box and rotatingly supported by said end walls, a flexible shield having one end connected to said shaft and adapted to be rolled up on the shaft by rotation of the shaft, and a guiding frame guidingly engaging the lateral edges of said shield, said guiding frame being connected to said box and forming an assembly therewith adapted to be mounted as a unit in operative relation to the wall opening, actuating means for driving said shaft, an adjustably mounted transmission outside one of said end walls connecting said actuating means to said shaft and having a housing, and support rails on said one end wall supportingly engaging said housing and providing guiding means therefor, said guiding means being in the form of opposed U shaped support rails.
