Abstract: A stationary base plate, a chain drum locking mechanism and a reducer mechanism are provided for a manual rolling door operator, in which the reducer mechanism has an output shaft and the chain drum locking mechanism has a chain drum, a wedge wheel, a drive shaft, a plurality of moving rollers, and fixed rods. If the chain drum is rotated in any direction by a force pulling a chain run around the chain drum, the fixed rods push against the moving rollers to release a wedging action from the wedge wheel which simultaneously renders the drive shaft to be rotated. However, if the force stop to pull the chain, the wedge wheel locks the moving roller by the wedging action due to the weight of a curtain of slats so as to stop the rotation of the drive shaft.

Abstract: A partition mount system includes an integrated plunger assembly. The integrated plunger assembly is constructed and arranged to be integrated into an interior of an end of an extension pole, for example a standard telescoping extension pole. Mounting of the plunger in an interior portion of the pole in this manner provides for a sleek design that is relatively lightweight. Assuming that the pole in which the anchor is mounted is part of a telescoping pole system, the anchor and plunger do not interfere with full travel of the interior pole with respect to other poles in the telescoping system. In this manner, operation of the telescoping pole system is not inhibited by the integrated plunger assembly.

The gear (7) and the reeling drum (2) are rotatable in the winding or releasing direction by pulling the pull rope (12) downward without actuating the rack (9).

Abstract: Each screen (1) of a group of screens is configured by a method in which a function is approximated, the function giving the instantaneous axial position (H(t)) of the load bar (2) thereof along an axis (Z) of translation in the form of a function having, as a variable, the instantaneous angular position (y(t)) of a winding device (4). The load bars of the screens are sequentially moved into a plurality of positions in which the load bars are aligned, and then the angular position (y(t)) of the winding device is determined. Next, the coefficients defining the approximation function of each screen are determined. The movement of the load bar of each screen is controlled by an instantaneous angular-position set value (?(t)), which is in turn predetermined from a representative profile using the one-to-one approximation function.
