Patent number: 7830600Abstract: An electric roll-up limit device includes a tube coupled by a tube rotor to an electric motor. The tube rotor contains a rocker bar that extends from the tube and activates a lower limit switch when a sheet of material is fully unrolled from the tube. A base below the tube rotor contains a pull bar cavity and an actuator device with a rotatable support frame and a rotatable actuator lever. The support frame supports the actuator lever and prevents it from rotating in one direction to activate an upper limit switch. A spring couples the rotation of the support frame and the actuator lever. When the sheet is fully rolled onto the tube, the pull bar cap retracts into the pull bar cavity and butts against the support frame. This causes the support frame to release the actuator lever, which then rotates to activate the upper limit switch.Type: GrantFiled: February 27, 2008Date of Patent: November 9, 2010Assignee: Sachii Fergameri Overseas Inc.Inventor: Guoliang Jiang

Patent number: 7617860Abstract: An elevator door system includes a motor rotating a vertical reel, and an elevator door. The door can be formed of a plurality of vertically aligned rigid panels or can be a sheet of material which is rigid or reinforced in the vertical direction or can have any other appropriate form making it suitable for being wound upon and unwound from the reel. The door is mounted to a flexible force transmission member provided along an entire width of the door and interconnected to the reel. Accordingly, the forces generated by the motor for opening and closing the door are substantially transmitted through the transmission member rather than being imparted onto the door itself. Hence, in use the strain on the door is greatly reduced and therefore the quantity of material used for the door and consequently its cost and mass can be reduced without deteriorating performance.Type: GrantFiled: October 19, 2006Date of Patent: November 17, 2009Assignee: Inventio AGInventor: Peter A.

The channel has first and second side walls that extend from an interior portion of the tubular wall toward the exterior surface. The second side wall extends further away from the longitudinal axis of the roller tube than the first side wall. This creates a lip in the exterior surface of the roller tube, enabling the attachment insert to be mounted flush with the exterior surface of the roller tube and avoiding any bumps from being formed in the sheet material as it is wound around the tube. The tube wall varies in thickness and has a relatively thick section to accommodate the channel being formed therein.Type: GrantFiled: March 3, 2006Date of Patent: November 10, 2009Inventor: Stephen Lukos

Patent number: 7448426Abstract: A power-off door closing device of fire proof rolling door in which the rolling door slides down to close by its own weight under abnormal power-off condition by brake-releasing action or by brake-applied action of a braking pin actuated by a energized solenoid, through successive movement of the first end of a sliding lever of a solenoid with a bent arm, a clamp member and a brake actuating rod. This device can be easily changed into non-failsafe door closing fire proof type with original configurations wherein the solenoid is reverse located so that the brake-released action caused by an energized solenoid or the brake-applied action under abnormal power-off condition applies. A reserved power supply temporarily energizes the solenoid to maintain a temporary brake-releasing under abnormal power-off condition, to enable the rolling door sliding down to close by its own weight.Type: GrantFiled: November 29, 2004Date of Patent: November 11, 2008Inventor: Chung-Hsien Hsieh

Publication number: 20080236763Abstract: An electronically-controlled roll-up window shade that can easily be installed by a homeowner or general handyman is disclosed. The motorized shade includes an internal power source, a motor, and a communication system to allow for remote control of the motorized shade. One or more motorized shades can be controlled singly or as a group. In one embodiment, the motorized shades are used in connection with a zoned or non-zoned HVAC system to reduce energy usage. In one embodiment, the motorized shade is configured to have a size and form-factor that conforms to a standard manually-controlled motorized shade. In one embodiment, a group controller is configured to provide thermostat information to the motorized shade. In one embodiment, the group controller communicates with a central monitoring system that coordinates operation of one or more motorized shades. In one embodiment, the internal power source of the motorized shade is recharged by a solar cell.Type: ApplicationFiled: June 11, 2008Publication date: October 2, 2008Inventor: Lawrence Kates
