Abstract:
The invention relates to door leaf element for a sliding door system, which is characterized in that the door leaf element (2) can be slid along a guide rail (7, 42) and can be swiveled about a first and a second swivel axis (25). A door closer (16) forms an integral part of the door leaf element (2) and/or an arm of a lever (12, 13) is disposed in the door leaf element. The door leaf element (2) is guided by means of guiding elements (9) in an upper and a lower end area.
Abstract:
A motorized window operator for opening and closing a window having a mechanical drive system including a rotatable drive axle. A housing contains a motor which is in operative engagement with a gear train having an output gear. The output gear is engageable with an engagement means mounted upon the drive axle of the window. For engaging the output gear train with the engagement means, operation of the motor will rotate the drive axle to either open or close the window according to desire. The gear train is dissengageable from the engagement means which at the same time dissengages power to the motor. The drive axle can then be manually operated.
Abstract:
A door closer the closing force of which can be adjusted is provided with a device for indicating the selected closing force. The device used to indicate the prevailing closing force is actuated in dependence on the adjustment of the spring which determines the closing force.
Abstract:
The synchronizing mechanism for the unfolding of articulated carrier elements which are outwardly extendable or inwardly retractable in a bellows-type arrangement on each side of a satellite body comprises a system of gear-train units placed alternately at one end of a driving carrier element. The mechanism is adapted to cooperate with at least one drive motor for folding-back or unfolding the carrier elements.
