Patent ID: 8459329

Claim:
A flexible partition roller system for positioning a flexible partition at a desired vertical position relative to a ceiling comprising: a flexible partition including a top edge having a coupling for suspending the partition from a ceiling, a bottom edge, and side edges, an elongated cylinder extending from one side edge of the partition to an opposite side edge, the cylinder being connected to the partition and dividing the partition into an upper and lower portion, an outer bearing fixed to an outside surface of a first end of the elongated cylinder, the outer bearing having an outside surface including a protrusion extending radially with respect to the elongated cylinder, an arm having a proximal end coupled to the outer bearing outer surface, the outer bearing permitting rotation of the elongated cylinder with respect to the arm, the outer bearing outer surface protrusion inhibiting any axial motion of the arm relative to the elongated cylinder, and a counterweight fixed to a distal end of the arm, to inhibit movement of the arm during any rotation of the elongated cylinder, a motor having a rotor portion and a stator portion, the rotor portion being coupled to the elongated cylinder for rotating the cylinder, and a bracket fixed to the stator portion of the motor and to the arm proximal end, the bracket extending over the protrusion of the outer bearing to couple the arm to inhibit rotation of the stator during any rotation of the elongated cylinder.
