Abstract:
PROBLEM TO BE SOLVED: To obtain an inexpensive cable tension adjusting mechanism for a window opening/closing device which enables simultaneous tension adjustment of an upper and a lower cables of the mechanism in a non-irreversible manner. SOLUTION: The cable tension adjustor comprises two cams 3, 4 and a torsion spring 2. The two cams are mounted opposite to each other to be rotatable around an axis 1. The torsion spring centered at the shaft 1 includes a first end section 8 stopped by the first cam 3 of the cams and a second end section 9 stopped by the second cam of the cams. The torsion spring 2 torques each of the cams 3, 4 whereby an angular distance between the cams is reduced when the cable tension is insufficient. COPYRIGHT: (C)2006,JPO&NCIPI
Abstract:
A motor driving a garage door is controlled by a controller, and the rotation of the motor in the normal and reverse directions is normally controlled in response to an actuating signal applied to the controller from a main push button switch. In a specific-mode in which an actuating signal is applied to the controller from an emergency push button switch, a mat switch or a fire sensor, the latter signal has priority over the former signal, and the motor is driven to move the garage door to its full-open position.
Abstract:
The disclosure is directed to motorized closure assembly, comprising: an opening frame configured to fit around the opening; a substantially rectangular closure slab having a closure slab frame configured to surround the substantially rectangular closure slab and sealingly fit within the opening frame; and a motorized driver, wherein the motorized driver is entirely embedded within the closure slab frame or within a combination of the closure slab frame and the opening frame, the motorized driver configured to slidably move the slab between an open position and a closed position.
Abstract:
Eine Spannvorrichtung zum Spannen eines Zugelements wenigstens eines entlang einer Führungsschiene oder dergleichen verschiebbaren Schiebeflügels umfasst ein vom Zugelement umschlungenes Umlenkelement, ein Verstellelement, an dem das Umlenkelement gelagert ist, sowie ein relativ zur Führungsschiene festlegbares Basisteil, in dem das Verstellelement in und entgegen der Spannrichtung verschiebbar geführt ist, wobei das Verstellelement relativ zu dem Basiselement entgegen einer Federkraft in eine durch eine lösbare Rastverbindung zwischen Verstellelement und Basiselement definierte Ausgangsposition verschiebbar und durch Lösen der Rastverbindung aus dieser Ausgangsposition wieder freiggebbar ist.
