Description

Die Erfindung betrifft eine Drehkreuzanlage für eine Personendurchgangskontrolle mit einem um eine gegenüber einer Horizontalen um etwa 45° geneigte Drehachse drehbaren und mittels einer entriegelbaren Sperrvorrichtung in wenigstens einer Drehrichtung gegen Drehung sperrbaren bzw. zur Drehung freigebbaren Sperrelement, das einen Lagerteller und wenigstens zwei in Umfangsrichtung beabstandet voneinander von diesem im Winkel zur Drehachse vorstehende Sperrarme besitzt, die infolge Drehung des Sperrelements um seine Drehachse nacheinander aus einer im wesentlichen horizontalen, einen Personendurchgang sperrenden Sperrposition in eine den Durchgang freigebende Drehstellung betätigbar sowie um quer zur Längsachse des jeweiligen Sperrarms verlaufende Anlenkachsen abklappbar am Lagerteller angelenkt und jeweils mittels eines am Lagerteller verschwenkbar gelagerten und durch Federkraft in ihren Verriegelungslagen gehaltenen Sperriegels in ihren normalen Betriebsstellungen verrastet sind, wobei die Sperriegel jeweils bei in Sperrposition stehendem Sperrarm mittels einer federkraftbeaufschlagten und durch einen Elektromagneten in Vorspannlage gehaltenen Entriegelungsvorrichtung bei Wegfall der magnetischen Haltekraft in ihre den jeweiligen Sperrarm zum Abklappen um seine Anlenkachse am Lagerteller aus seiner Sperrposition in eine den unbehinderten Personendurchgang zulassende Abklapplage freigebende Entriegelungsstellung betätigbar sind.The invention relates to a turnstile system for a Passage control with one by one opposite a horizontal axis of rotation inclined by approximately 45 ° rotatable and by means of an unlockable locking device in at least one direction of rotation against rotation locking element that can be locked or released for rotation, the one bearing plate and at least two in the circumferential direction spaced from each other at an angle has locking arms protruding to the axis of rotation which due to rotation of the locking element about its axis of rotation successively from an essentially horizontal, a blocked passage position in a rotary position enabling the passage can be actuated as well as transversely to the longitudinal axis of the respective locking arm Running articulation axes can be folded down on the bearing plate articulated and in each case by means of a on the storage plate pivoted and spring loaded in their Locking positions held locking bolt in their normal operating positions are locked, the Locking bolt each with the locking position Locking arm by means of a spring-loaded and held in bias position by an electromagnet Unlocking device when the magnetic Holding force in their respective locking arm to fold down around its pivot axis on the bearing plate from its Locked position in an unobstructed passage Allowable unfolding unlocking position are operable.

Derartige Drehkreuzanlagen werden in Verbindung mit Personenschleusen eingesetzt, um einen kontrollierbaren Eingang bzw. Ausgang von Personen zu ermöglichen. Der Durchgang durch diese Personenschleusen wird durch Weiterschalten eines Drehkreuzes in Abhängigkeit vorher definierbarer Kriterien freigegeben, die automatisierbar überprüfbar sind. Gleichzeitig soll bei derartigen Drehkreuzanlagen sichergestellt sein, daß in ausgewählten Situationen, wie beispielsweise Notfällen, ein unkontrolliertes und schnelles Passieren dieser Personenschleusen möglich ist.Such turnstile systems are used in conjunction with Security gates used to make a controllable Allow people to enter or exit. Of the Passage through these security gates is by switching of a turnstile depending on it beforehand definable criteria released that can be automated are verifiable. At the same time with such Turnstile systems must be selected Situations, such as emergencies, an uncontrolled and fast passage through these security gates is possible.

Eine solche Drehkreuzanlage ist beispielsweise aus der DE-OS 28 25 787 bekannt. Im Falle der Stromunterbrechung oder Abschaltung wird bei dieser Drehkreuzanlage ein Elektromagnet stromlos und eine Entriegelungsvorrichtung nicht länger in einer Vorspannlage gehalten. Ein Schieber der Entriegelungsvorrichtung wird dann durch Federkraft derart bewegt, daß er einen den Sperrarm haltenden Sperriegel so verschwenkt, daß er außer Eingriff mit einer mit dem Sperrarm verbundenen Lagerzunge gelangt. Im folgenden fällt der Sperrarm infolge der auf ihn wirkenden Schwerkraft in eine den Durchgang freigebende Abklapplage. Um die Drehkreuzanlage anschließend wieder einzurichten, muß der Sperrarm von Hand wieder in die Horizontallage verschwenkt werden, bis die Lagerzunge erneut mit dem Sperriegel verrastet. Zuvor muß der Schieber entgegen der auf ihn wirkenden Federkraft durch den Elektromagneten der Entriegelungsvorrichtung wieder in seine ursprüngliche Betriebsstellung bewegt werden.Such a turnstile system is from, for example DE-OS 28 25 787 known. In the event of a power cut or turn off with this turnstile system an electromagnet without current and an unlocking device no longer held in a pretension position. A slide of the unlocking device is then moved by spring force so that he one Locking arm locking bolt pivoted so that it disengaged from one connected to the locking arm Bearing tongue. In the following the locking arm falls due to the gravity acting on him Fold-out position that allows passage. Around the turnstile then set up again, the locking arm swung back into the horizontal position by hand until the bearing tongue is locked again locked. Previously, the slide must be counter to the one on it acting spring force by the electromagnet of the unlocking device back to its original Operating position are moved.

Diese Drehkreuzanlage muß mit einem starken Elektromagneten ausgestattet sein. Die Wiedereinrichtung von Hand nach einer Abschaltung ist insbesondere bei weitläufigen Betriebsgeländen recht umständlich.This turnstile system must have a strong electromagnet be equipped. The re-establishment of Hand after a shutdown is especially at extensive premises quite cumbersome.

Der Erfindung liegt daher die Aufgabe zugrunde, eine fernsteuerbare Drehkreuzanlage zu schaffen, die einen gegenüber dem Stand der Technik vereinfachten Aufbau und einen reduzierten Energiebedarf aufweist. Darüber hinaus soll die Anlage in weiterer Ausgestaltung nach einer Abschaltung weitestgehend selbsttätig wieder in die normale Betriebsstellung gelangen.The invention is therefore based on the object remote controllable turnstile system to create one simplified structure compared to the prior art and has a reduced energy requirement. About that In addition, the plant should be in a further design a shutdown largely automatically back in get the normal operating position.

Bei einer Drehkreuzanlage gemäß dem Oberbegriff des Anspruchs 1 wird diese Aufgabe dadurch gelöst, daß die Sperriegel als in Abhängigkeit von der Betriebsstellung des jeweils zugeordneten Sperrarms mittels eines Lagerkörpers des Sperrarms verschwenkbare doppelarmige Hebel ausgebildet sind, wobei der eine Hebelarm mit dem Lagerkörper in Eingriff bringbare Rastmittel und der andere Hebelarm eine von dem Lagerkörper des in Abklapplage schwingenden Sperrarms betätigbare Rückstelleinrichtung für die Entriegelungsvorrichtung aufweist.In a turnstile system according to the preamble of Claim 1 this object is achieved in that the Locking bolt as a function of the operating position of the respectively assigned locking arm by means of a Bearing body of the locking arm pivotable double-armed Levers are formed, the one lever arm with the bearing body engageable locking means and the other lever arm one of the bearing body of the in Folding position swinging locking arm actuable reset device for the unlocking device having.

Dadurch, daß die Sperriegel jeweils mit einer Rückstelleinrichtung versehen sind, wird die Entriegelungsvorrichtung ohne zusätzlichen Energieaufwand in ihre Vorspannlage zurückbewegt, während der Sperrarm in die Abklapplage schwingt. Der Elektromagnet der Entriegelungsvorrichtung hat somit ausschließlich eine Haltefunktion. Er kann dementsprechend kleiner ausgeführt werden, so daß auch der Haltestrom des Elektromagneten reduziert ist.The fact that the locking bolt each with a reset device are provided, the unlocking device without additional energy expenditure in your Preload position moved back while the locking arm in the Folding position swings. The electromagnet of the unlocking device therefore only has a holding function. Accordingly, it can be made smaller be so that the holding current of the electromagnet is reduced.

Nach Anspruch 2 ist die Arretierung des Sperrarms in seiner Sperrposition dadurch wesentlich vereinfacht, daß eine federkraftbeaufschlagte Riegelnase des Sperriegels mit der Riegelschulter eines mit dem Sperrarm verbundenen Lagerkörpers verrastet.According to claim 2, the locking of the locking arm is in its locking position considerably simplified in that a spring-loaded bolt nose of the locking bolt with the bolt shoulder one connected to the locking arm Bearing body locked.

Gemäß einer Weiterbildung nach Anspruch 3 weisen die Sperriegel auf der dem Lagerkörper des jeweiligen Sperrarms zugewandten Seite eine Aussparung und eine ansteigende Kurvenbahn auf, mit der beim Abklappen des Sperrarms der Nocken des zugeordneten Lagerkörpers zusammenwirkt. Dadurch ist sichergestellt, daß der Nocken des Lagerkörpers am Anfang des Abklappvorganges quasi ungehindert unterhalb des Sperriegels schwingen kann und am Ende des Abklappens über die ansteigende Kurvenbahn die Entriegelungsvorrichtung wieder spannt. Hierdurch ist die Funktionssicherheit der Drehkreuzanlage in der Weise erhöht, daß im Falle der Abschaltung der Sperrarm vollständig in die vertikale Abklapplage herabfällt. Bei Stromwiederkehr gelangt die Entriegelungsvorrichtung wieder in ihre ursprüngliche Vorspannlage. Das Wiedereinrichten der Drehkreuzanlage ist somit durch bloßes Weiterschalten des Lagertellers möglich, da der entlang der Aussparung zurückschwingende Nocken wieder mit dem Sperriegel verrastet.According to a development according to claim 3, the Locking bolt on the bearing body of the respective locking arm facing side a recess and a rising Curve path with which when the locking arm is folded down the cam of the associated bearing body interacts. This ensures that the cam the bearing body at the beginning of the folding process, so to speak can swing freely underneath the locking bolt and at the end of the folding over the ascending curve track the release device tensions again. This ensures the functional reliability of the turnstile system increased in such a way that in the event of shutdown the locking arm completely in the vertical fold-down position falls down. When power returns, the Unlock device back to its original Preload position. Reinstalling the turnstile system is thus by simply advancing the bearing plate possible because the one swinging back along the recess Cam locked again with the locking bolt.

Nach Anspruch 4 ist die Entriegelungsvorrichtung der Drehkreuzanlage jeweils nur mit dem in Sperrposition befindlichen-Sperrarm in Eingriff bringbar. Hierdurch wird im Falle einer Abschaltung oder bei Stromausfall nur der jeweils den freien Durchgang durch die Personenschleuse sperrende Sperrarm abgeklappt. Demzufolge muß bei der Wiedereinrichtung der Drehkreuzanlage auch nur ein Sperrarm wieder verrastet werden.According to claim 4, the unlocking device Turnstile system only with the one in the locked position locking arm can be brought into engagement. Hereby in the event of a shutdown or power failure only the free passage through the security gate locking arm folded down. Therefore must even with the re-establishment of the turnstile system a locking arm can be locked again.

Mit der Ausgestaltung nach Anspruch 5 ist ein passives Sicherheitssystem verwirklicht, da im Falle einer Stromunterbrechung oder Stromabschaltung das Abklappen des jeweils sperrenden Sperrarm selbsttätig ausgelöst wird. Hierzu ist eine erste Schraubenfeder vorgesehen, die im Falle der Auslösung eine an den Führungsstangen befestigte Auslöseplatte derart gegen den nasenartigen Vorsprung des Sperriegels drückt, daß dieser Sperriegel außer Eingriff mit dem Lagerkörper des Sperrarms gelangt. Die Auslösung des Sperriegels erfolgt demnach rein mechanisch. Hierdurch ist eine hohe Funktionssicherheit der Auslösung gewährleistet. Dies ist insbesondere im Falle einer Notabschaltung ein entscheidender Vorteil.With the configuration according to claim 5 is a passive Security system implemented as in the event of a power cut or power cut off the folding of the blocking arm is triggered automatically. A first coil spring is provided for this purpose if triggered, one attached to the guide rods Trigger plate so against the nose-like Projection of the locking bar presses that this locking bar out of engagement with the bearing body of the locking arm reached. The lock bolt is triggered accordingly purely mechanical. This ensures a high level of functional reliability the triggering guaranteed. This is particularly so a crucial one in the event of an emergency shutdown Advantage.

Jeweils eine zweite schwächere Schraubenfeder, die auf Führungsstangen der Auslöseplatte aufgenommen sind, wirkt entgegen der Federkraft der ersten Schraubenfeder und verhindert somit ein ungebremstes Auftreffen der Auslöseplatte auf den nasenartigen Vorsprung des Sperriegels. Diese Ausgestaltung des Erfindungsgegenstandes reduziert den Verschleiß der Anlage und erhöht somit deren Lebensdauer. Die zweiten Schraubenfeern halten ferner eine metallische Halteplatte, die auf den Führungsstangen der Auslöseplatte zwischen den Schenkeln der Haltekonsole aufgenommen ist, in Anlage an auf den Führungsstangen angeordneten Sprengringen. In each case a second weaker coil spring on Guide rods of the release plate are received, acts against the spring force of the first coil spring and thus prevents an unchecked impact the release plate on the nose-like projection of the Locking bolt. This embodiment of the subject matter of the invention reduces system wear and increases hence their lifespan. The second screw fires also hold a metal holding plate on the guide rods of the release plate between the Legs of the holding bracket is included in the system on snap rings arranged on the guide rods.

Dadurch, daß die Auslöseplatte der Entriegelungsvorrichtung in ihren seitlich über die Führungsstangen überstehenden Bereichen Auflauframpen aufweist, ist sichergestellt, daß beim Weiterschalten des Lagertellers die sich unter der in Vorspannlage gehaltenen Auslöseplatte hindurch drehenden Nocken des Lagerkörpers nicht mit der Auslöseplatte in Anschlag gelangen. Dies ist insbesondere beim Wiedereinrichten der Drehkreuzanlage durch bloßes Weiterschalten des Drehtellers ein die Funktionssicherheit erhöhender Vorteil.The fact that the release plate of the unlocking device in their protruding laterally over the guide rods Areas has ramp ramps, it is ensured that when switching the bearing plate under the release plate held in the pretension position rotating cams of the bearing body not with the release plate to go to the stop. This is particularly the case with Reinstall the turnstile system simply by switching on of the turntable the functional reliability increasing advantage.
