Abstract:
PROBLEM TO BE SOLVED: To provide a combined door having a characteristic for reducing dangerous damages. SOLUTION: A header section 3' is guided on a traveling rail 6 which horizontally extends to a door frame 1 and has a vertical end segment 7 on a frame side. The other sections 3 following the header section 3' are guided by a guide rail 9 having a vertical segment along the door frame 1 and a horizontal segment parallel to the traveling rail 6 holding the header section, as well as having an arc connecting the two segments. A door driving means 5 which is fitted to one of the sections 3 connected under the header section 3' has at least one power take-off spindle 10 fitted to the section 3 and is provided with a vane wheel 11 at its end. The vane wheel 11 for power transmission is engaged with the guide rail 9 of the section 3 and moves a door panel 2. COPYRIGHT: (C)2005,JPO&NCIPI
Abstract:
A retrofitable retractable screen system suitable for use with windows including small caravan windows. A retractable screen is mounted on a spindle, and a cord is guided from a spindle pulley within a side frame member through a compact double backed path to an end panel attached to the distal end of the screen. A tension adjustment arrangement is either located behind an end panel attached to the distal end of the screen with a compact profile to allow it to be fitted to small windows. A tension adjustment arrangement is either located within the side housing or a screen cross bar adjusts the tension in the cord as the screen is wound and unwound from the spindle to provide a smooth mechanism to extend and retract the screen. The system can include two screens, such as a blind and an insect screen, each located at opposite ends of the frame.
Abstract:
Die vorliegende Erfindung betrifft einen Aktuator mit einer rückensteifen Kette, einem Antriebs- motor, und einer vom Antriebsmotor antreibbaren Schnecke mit Wendelnut, wobei die rücken- steife Kette Eingriffsmittel aufweist und an der Schnecke entlanggeführt ist und mit dieser zum Antreiben der rückensteifen Kette mittels der Eingriffsmittel und der Wendelnut im Eingriff steht. Ein solcher Aktuator soll kompakter und gegebenenfalls verschleißärmer ausgeführt werden. Hierzu ist der Kerndurchmesser der Schnecke größer als der doppelte Abstand der Motorachse zur Motorseite, an der die rückensteife Kette entlanggeführt ist, und die rückensteife Kette mit den Eingriffsmitteln zumindest teilweise am Antriebsmotor entlanggeführt.
Abstract:
A door closer or operator includes a pivoting pinion on the door closer housing for transmitting door motion, and a cam connected thereto. A connecting member extends along a spring and engages the peripheral edge of the cam. Rotation of the cam causes a change in length of the portion of the connecting member between the position tangent to the cam peripheral edge and the spring second end to expand or compress the spring, resulting in a force transmitted along a longitudinal axis of the connecting member as a result of spring deflection. The cam peripheral edge has a profile with a varying radial distance between the cam axis and the connecting member at the position tangent to the cam peripheral edge such that the radial distance is changed as the spring expands or compresses to maintain a desired constant torque about the axis of the cam and pinion.
