Aus Sicherheitsgründen ist an der Innenseite der Schiebetür der Hebel mit einem Notöffnungssystem versehen, das es eingeschlossenen Personen gestattet, die Verriegelung der Tür von innen im Notfall zu lösen.Sliding doors with locking devices are preferred in walk-in and accessible cold rooms, cold stores and warehouses etc. For safety reasons, the lever is on the inside of the sliding door an emergency opening system that allows trapped people, release the locking of the door from the inside in an emergency.

Darstellung der ErfindungPresentation of the invention

Aufgabe der Erfindung ist es, eine elektrisch steuerbare, besonders einfache und zuverlässige Verriegelungseinrichtung zu schaffen.The object of the invention is an electrically controllable, particularly simple and to create reliable locking device.

Die Erfindung löst diese Aufgabe durch die Merckmale des kennzeichnenden Teils des Anspruchs 1 und sie besteht darin, daß bei einer Verriegelungseinrichtung der genannten Art mit Notöffnungshebel, einem davon betätigten Steuernocken und einem vom Steuernocken bewegten Kipphebel mit Haken, auf den anderen Arm des Kipphebels ein Elektromagnet einwirkt und daß eine Einlaufschräge des Hakens auf einem ortsfesten Bolzen ruht. Dabei liegt in einer Grundstellung die Einlaufschräge als Steuerweg zwischen dem Bolzen und dem Haken.The invention solves this problem by the features of the characterizing part of claim 1 and it consists in the fact that in a locking device said Type with emergency opening lever, one of which actuated control cams and one rocker arm with hook moved by the control cam, on the other Arm of the rocker arm acts on an electromagnet and that an inlet slope the hook rests on a fixed bolt. It is in a basic position the entry slope as a control path between the bolt and the hook.

Bei Betätigung der Tür auf diesem Steuerweg senkt sich der Kipphebel in eine Sperrstellung ab, wenn weder der Elektromagnet erregt noch das Notöffnungssystem betätigt ist. In dieser Sperrstellung rastet der Bolzen im Hakenmaul ein und die Tür kann nicht weiter geöffnet werden. Bei erregtem Elektromagnet oder im Notöffnungsfall wird der Kipphebel vom Magneten oder dem Steuernocken in seiner Ausgangsstellung gehalten, damit der Haken den ortsfesten Bolzen passieren kann und die Tür sich aufschieben läßt.When the door is operated in this way, the rocker arm lowers a blocking position if neither the electromagnet excites nor the emergency opening system is operated. In this locked position, the bolt snaps into the hook mouth on and the door cannot be opened any further. When the electromagnet is energized or in the event of an emergency opening, the rocker arm is released from the Magnet or the control cam held in its original position so that the hook can pass the stationary bolt and the door can be pushed open leaves.

Bei einem bevorzugten Ausführungsbeispiel der Erfindung ist die damit ausgerüstete Schiebetür so ausgebildet, daß die der Verriegelungseinrichtung benachbarte Rolle in einer Mulde der Laufschiene ruht, wodurch sich eine definierte Schließlage ergibt. In a preferred embodiment of the invention, the one equipped with it Sliding door designed so that the locking device adjacent role rests in a trough of the running rail, causing a defined closed position results.

In Fig. 1 ist mit 1 der Laufwagen bezeichnet, der u.a. am linken Ende eine Rolle 2 trägt. Unter dem Laufwagen ist eine ortsfeste Laufschiene 3 angeordnet, die am Ort der Rolle 2 eine Rastmulde 3a aufweist. Am linken Rand ist die Türzarge 4 angeordnet. Die Laufschiene 3 trägt einen Bolzen 5. Zur eigentlichen Verriegelungseinrichtung gehört eine Platine 6, die über Bohrungen 6a, 6b mit dem Laufwagen 1 verschraubt ist.In Fig. 1, 1 denotes the carriage, which among other things. at the left end carries a role 2. There is a stationary track 3 under the carriage arranged, which has a locking recess 3a at the location of the roller 2. On the left The edge of the door frame 4 is arranged. The running rail 3 carries a bolt 5. A circuit board 6 belongs to the actual locking device is screwed to the carriage 1 via bores 6a, 6b.

Im unteren Bereich der Platine 6 ist ein Steuernocken 7 auf einem Bolzen 8 schwenkbar gelagert. An einem linken Vorsprung 7a greift eine Zugstange 9 an. Eine Zugfeder 10 hält den Steuernocken 7 in der dargestellten Ruhelage. Bewegt man die Stange 9 mit dem nicht dargestellten Öffnungshebel nach unten, so drückt die Steuerfläche 7b gegen einen Kipphebel 11. Dieser Hebel besteht aus einem längeren linken Arm, der einen Haken 11a aufweist, und einem kürzeren rechten Arm, der den Anker 12a eines Elektromagneten 12 trägt. Der Lagerbolzen 13 für den Kipphebel 11 liegt zwischen dem Aufsetzpunkt 11b des Steuernockens 7 und dem Anker 12.In the lower area of the circuit board 6 there is a control cam 7 on a pin 8 pivoted. A pull rod engages on a left projection 7a 9 on. A tension spring 10 holds the control cam 7 in the rest position shown. If you move the rod 9 with the opening lever, not shown downward, the control surface 7b presses against a rocker arm 11. This Lever consists of a longer left arm, which has a hook 11a and a shorter right arm, the armature 12a of an electromagnet 12 carries. The bearing pin 13 for the rocker arm 11 is between the touchdown point 11b of the control cam 7 and the armature 12.

In der gezeichneten Grundstellung (geschlossene Tür) ruht der Kipphebel 11 auf dem Bolzen 5. Er befindet sich am Beginn der Einlaufschräge 11c des Hakenmauls.The rocker arm is at rest in the basic position shown (closed door) 11 on the bolt 5. It is located at the beginning of the inlet slope 11c of the hook's mouth.

In Fig. 2 ist die Verriegelungseinrichtung allein nochmals in Grundstellung gezeichnet.
Wenn man die Zugstange 9 über einen auf der Innenseite oder einen zusätzlich auf der Außenseite angebrachten Griff betätigt, so wird der Steuernocken 7 entsprechend Fig. 3 nach links gekippt, bis sich die Steuerfläche 7b an den Aufsetzpunkt 11b des Kipphebels 11 anlegt. Zugleich wandert die Tür nach rechts. Die Rolle 2 verläßt die Mulde 3a der Laufschiene und hebt dabei das Türblatt leicht an. Da der Kipphebel 11 hochgehalten wird, läuft der Haken 11a über den Bolzen 5, und die Tür kann aufgeschoben werden.In Fig. 2 the locking device alone is drawn again in the basic position.
If the pull rod 9 is actuated via a handle on the inside or an additional handle on the outside, the control cam 7 is tilted to the left in accordance with FIG. 3 until the control surface 7b bears against the contact point 11b of the rocker arm 11. At the same time, the door moves to the right. The roller 2 leaves the trough 3a of the running rail and slightly raises the door leaf. Since the rocker arm 11 is held up, the hook 11a runs over the bolt 5 and the door can be pushed open.

Fig. 4 zeigt die Lage der Teile bei der Öffnung der Tür über einen automatischen Antrieb. Die Entriegelung erfolgt über einen elektrischen Impuls, der beim Starten von einer Codetastatur oder einem Kartenleser ausgeht und den Elektromagneten erregt. Bei angezogenem Anker 12a kann der Haken 11a über den Bolzen 5 hinweglaufen.Fig. 4 shows the position of the parts when opening the door via an automatic Drive. The release takes place via an electrical impulse, starting from a keypad or a card reader and excited the electromagnet. When the anchor 12a is tightened, the hook can 11a run over the bolt 5.

Fig. 5 zeigt den Ablauf, wenn weder ein Impuls anliegt noch der Außen- oder Innenhebel betätigt ist.
Mit dem Beginn des Steuerweges rutscht die Einlaufschräge 11c des Kipphebels 11 über den Bolzen 5. Da der Schwerpunkt des Hebels 11 links vom Lagerbolzen liegt, kippt der Hebel unter Ablösen des Ankers 12a nach links, bis die Blockadestellung erreicht ist.
Die Kippbewegung des Hebels 11 kann abweichend von der Darstellung auch durch eine Zugfeder ausgelöst werden.
Es ist ein besonders vorteilhaftes Merkmal der Erfindung, daß die Tür nicht permanent hart verriegelt ist, sondern in einer Verriegelungsbereitschaft steht. Erst bei Beginn der Türbewegung, also beim Zurücklegen der Steuerstrecke, wird ein evtl. vorhandener Öffnungsbefehl abgefragt und umgesetzt.Fig. 5 shows the sequence when neither a pulse is present nor the outer or inner lever is actuated.
With the beginning of the control path, the lead-in slope 11c of the rocker arm 11 slides over the bolt 5. Since the center of gravity of the lever 11 is to the left of the bearing bolt, the lever tilts to the left while releasing the armature 12a until the blocking position is reached.
Deviating from the illustration, the tilting movement of the lever 11 can also be triggered by a tension spring.
It is a particularly advantageous feature of the invention that the door is not permanently locked hard, but is ready to lock. An opening command, if any, is only queried and implemented at the start of the door movement, i.e. when the control section is covered.

Gewerbliche VerwertbarkeitCommercial usability

Die beschriebene Ver- und Entriegelungseinrichtung kann sowohl bei lediglich von Hand aufzuschiebenden Türen oder Toren als auch bei motorbetätigten Einheiten benutzt werden. In jedem Fall muß aber innen ein Notauslösegriff vorgesehen sein, damit man unabhängig von Hilfsenergien (Strom oder Druckluft) einen Fluchtweg öffnen kann.The described locking and unlocking device can be used for both doors or gates to be pushed open by hand as well as motor-operated ones Units are used. In any case, there must be an emergency release handle on the inside be provided so that one is independent of auxiliary energy (electricity or compressed air) can open an escape route.

In der bevorzugten Ausführungsform ist auch auf der Außenseite der Tür ein Handgriff angeordnet, der über ein Zylinderschloß blockiert oder von der Zugstange 9 des Notöffnungssystems entkuppelt werden kann. Im Normalbetrieb ist der äußere Handgriff blockiert oder entkuppelt, also ohne Funktion. Lediglich bei einem Versagen der elektrischen Ansteuerung wird der Schlüssel benutzt, um eine Notöffnung von Hand zu bewirken. In the preferred embodiment is also on the outside of the door a handle arranged that blocks via a cylinder lock or from the pull rod 9 of the emergency opening system can be uncoupled. In normal operation the outer handle is blocked or uncoupled, i.e. without Function. Only if the electrical control fails the key is used to make an emergency opening by hand.
