Abstract:
The invention relates to a power transmitting arrangement for doors, preferably revolving or swinging doors with door leaves (30) moving in a circular path inside lateral partitions (33) and useful for both driving and braking means (13, 22) for the operation and braking of the door. Between a stationary element (K1) and a relatively same element displaceable element (K2) is arranged a power transmission including an engagement surface (Y) at the one element and at least one engagement means (18, 23) at the other element wherein power such as motor power for the operation of the door and/or inertia derived from the door on the braking of the same is transmitted utilizing at least one obliquely against the surface of engagement (Y) arranged and such engagement means carrying swingably arranged arm so movable that the power engagement increases with increasing torque.
Abstract:
A motor driven revolving door, also called a roundabout entrance, providing an air lock and comprising a revolving central body (5) with door leaves, each of which may be swung in either direction from a mainly radial rest position around a vertical axis at some distance from the revolving axis of the central body (5). The central body (5) is sustained by one bearing only placed at the bottom just above or in floor level, and the bearing is designed to absorb both radial and axial forces as well as tilting moments, aiming at tilting the revolving axis away from its vertical position. In comparison with other roundabout entrances it is now possible to obtain freelier transparent designs, and simpler sealing between the revolving central body (5) and the floor and ceiling respectively, the ceiling construction can be simplified and therefore less costly, also the required work on the installation site is simplified and less expensive.
Abstract:
Embodiments of electric motor driven door or barrier opener with a manually operable drive for use in the event of a power failure are provided. The operator comprises a gear box drive connectable with an electric motor of said operator, said gear box comprising an output for drive coupling with said door to effect opening and closing of said door by said motor and a shaft that drive rotates when said motor rotates. The shaft carries a free wheeling manually rotatable drive wheel as said manually operable drive and useable in the event of power failure to effect manual drive rotation movement of said shaft to open and close the door via said gearbox. The manually rotatable drive wheel comprises at least one drive coupler mounted to move in a generally radially extending direction relative to a central longitudinal axis of said shaft so that manual rotation of said drive wheel in the event of a power failure will effect a movement of the at least one drive coupler in the generally radially extending direction to effect a drive coupling between said drive wheel and said shaft to input drive to said shaft to permit manual opening and or closing of said door.
Abstract:
Electro-mechanical and electronically controlled access devices are described for controlling access to a building, premises or area in a secure manner such that a subject who is deemed ineligible for access will be barred entry and may be optionally retained. The devices can contain multiple rotatable door panels, which can be positioned behind one another. The door panels can be controlled by mechanized arms or other control devices in order to control the passage through the device. The direction of flow through a device according to these embodiments is electronically controlled and may be changed at any point in time. At any instant in time, the flow through the device is unidirectional. Multiple devices can be stacked together to form clusters, which can be controlled according to traffic, time of day, or other factors.
Abstract:
A revolving driving force structure of a revolving wing for an automatic revolving door is provided, in which a revolving door of an automatic revolving door having an inner body with a revolving door at an inner side of an outer body provided at a front end of a transparent wall member is generated based on a rotation roller protruded from the inner body and by an operation motor which rotates the rotation door, and the rotation roller is supported on an inner support protrusion, and it is possible to prevent any safety accident based on a stable rotation of the inner body and the revolving wing and a constant gap during the rotation of the revolving wing, and a simple structure can be obtained, and a durability and life span increase without any load.
Abstract:
Die Erfindung richtet sich auf eine Türeinrichtung (10) mit mindestens einer Tür (11), zum Öffnen und Schließen eines Durchganges (27), wie sie in Kaufhäuser, öffentlichen Gebäuden od. dgl. verwendet wird. Die Türen (11) selbst sind in einer Türhalterung (12) bewegbar, z.B. drehbar oder längsverschiebbar gehalten. Weiter ist die Türeinrichtung (10) mit wenigstens einer Luftschleiereinrichtung (30) versehen, die sich im Wesentlichen über die ganze Höhe des Durchgangs (27) erstreckt und die einen austretenden Luftschleier (33) erzeugt, so dass der Durchgang (27) bei geöffneter Tür (11) durch den Luftschleier (33) abgeschirmt ist. Der erzeugte Luftschleier (33) dient dazu, den Energieverlust zu senk-en, der dadurch entsteht, das Luft aus dem Außenbereich (28) der Türeinrichtung (10) in den Innenbereich (29) der Türeinrichtung (10) gelangen kann oder umgekehrt. Um eine Türeinrichtung (10) zu erhalten, die nicht nur den Durchgang von Gegenständen und Personen ermöglicht, sondern gleichzeitig eine Identifizierung von den Personen, Gegenständen oder dgl. vornimmt und die Handhabung dabei möglichst einfach und unkompliziert vonstatten geht, wird vorgeschlagen, die Türeinrichtung (10) mit zumindest einem zusätzlichen Identifizierungssystem (40) zu versehen, Dieses Identifizierungssystem (40) weist zumindest eine Sensoreinheit (41) , eine Steuerungseinheit (42) und eine Ausgabeeinheit (43) auf, die miteinanderverbunden sind. Weiterhin ist zumindest eine Sensoreinheit (41) des Identifizierungssystems (40) in der Luftschleiereinrichtung (30) integriert.
