Abstract

An improved airtight closing sliding door with contact pressure and integrated one-hand operation which lowers itself in its closed position and thereby hermetically seals the door frame as well as the door sill by way of continuously effective contact pressure whose door leaf is suspended from the cam plate of a carrying shaft, and which is lowered from horizontally to vertically downwards position by turning the carrying shaft.

Description

Die Erfindung betrifft eine Schiebetür nach dem Gattungsbegriff des Anspruches 1, deren Türblatt zum Teil von einem auf einer Laufschiene mitrollen den, im verschlußseitigen Laufrollengehänge gelagerten Kipphebel und zum Teil von einer oder mehreren, separat gelenkig zwischen einer Tragwelle und einer Nockenscheibe einer Nockenwelle gelagerten Druckfedern hochgehalten wird und an den Nocken der Tragwelle aufgehängt ist und die sich in Verschlußstellung absenkt und dabei den Türrahmen sowie die Türschwelle durch einen ständig wirkenden Anpreßdruck hermetisch abdichtet (DD-PS 230 893).The invention relates to a sliding door according to the preamble of claim 1, the door leaf held up partly by a roller on a running track, the rocker arm mounted in the lock-side roller hanger and partly by one or more, separately articulated between a support shaft and a cam disk of a camshaft compression springs is and is suspended from the cams of the support shaft and which lowers in the closed position and thereby hermetically seals the door frame and the door sill by a constantly acting contact pressure (DD-PS 230 893).

Dieses hermetische Verschließen bzw. Öffnen erfolgt jeweils mit nur einer synchron ablaufenden technologischen Betätigung als Nachgang zum Zuschieben bzw. als Vorlauf zum Aufschieben sowohl mittels Handbetätigung als auch mittels motorischen Antriebs.This hermetic closing or opening takes place with only one synchronously operating technological operation as a follow-up for closing or as a lead for opening both by means of manual operation and by means of a motor drive.

Das selbständige Einfallen des Türblattes in die Verschlußstellung gewährleistet zusätzlich die Anordnung einer Selbstschließanlage.The independent falling of the door leaf in the closed position also ensures the arrangement of a self-locking system.

Das Anwendungsgebiet derartiger Schiebetüren ist der Einsatz als Kühlraum- und Gefrierraumtüren, als Feuerschutztüren oder als schalldämmende Türen im Bauwesen.The field of application of such sliding doors is the use as cold room and freezer room doors, as fire protection doors or as soundproofing doors in construction.

Bekannt sind Schiebetüren, die an einer durch Betätigungseinrichtung verdrehbaren Tragwelle aufgehängt sind und durch Betätigung nach dem Zuschieben radial abgesenkt werden.Sliding doors are known which are suspended from a support shaft which can be rotated by an actuating device and which are lowered radially by actuation after being closed.

Weiter bekannt sind Türen, die an im Schiebebereich nach außen gekippten Laufrollengehängen gelenkig aufgehängt und mit Stützrollen gegen eine Druckschiene abgestützt sind. In Verschlußstellung wird diese Abstützung freigegeben und das Türblatt fällt durch sein Eigengewicht ins Lot. Eine andere Art sind Schiebetüren, bei denen das Abdichten durch eine zum Fußboden und zur Wandfläche geneigte schiefe Ebene der Laufschiene erreicht wird. Und es gibt Schiebetüren, die in Verschlußstellung eine Vertiefung in der Laufschiene aufweisen, die sowohl senkrecht als auch diagonal sein können und damit das Türblatt absenken. Charakteristisch für alle vorgenannten Arten von Schiebetüren mit durch ihr Eigengewicht ins Lot fallenden Türblättern ist der fehlende horizontale Anpreßdruck, der für einen hermetischen Verschluß jedoch entscheidend ist. Das Öffnen und Schließen dieser Türen erfolgt durch separate Kurbeln oder Handräder, die über den Totpunkt einer Kreisbewegung in Hochlage gehalten werden und eine aufwendige Betätigung darstellen. Bei anderen Türen, deren Dichtung nur durch die schiefe Ebene erreicht wird, ist durch die sehr starke Reibung zusätzlich ein großer Kraftaufwand erforderlich.Also known are doors which are hingedly suspended on castor hangers tilted outwards in the sliding area and are supported with support rollers against a pressure rail. This support is released in the locked position and the door leaf falls vertically due to its own weight. Another type are sliding doors, in which the sealing is achieved by an inclined plane of the running rail inclined to the floor and to the wall surface. And there are sliding doors that have a recess in the running rail in the closed position, which can be both vertical and diagonal and thus lower the door leaf. Characteristic of all of the above-mentioned types of sliding doors with door leaves falling due to their own weight is the lack of horizontal contact pressure, which, however, is crucial for a hermetic closure. These doors are opened and closed by means of separate cranks or handwheels, which are held high above the dead center of a circular movement and represent a complex operation. With other doors, the seal of which can only be reached through the inclined plane, a great deal of effort is required due to the very high friction.

Es sind auch Türen bekannt, die durch Druckfedem an einer Tragwelle hochgehalten werden und bei denen der horizontale Anpreßdruck durch das Überkippen der Druckfedern beim Schließen erzeugt wird, was jedoch ein hartes Einwuchten des Türblattes zur Folge hat.Doors are also known which are held up by pressure springs on a support shaft and in which the horizontal contact pressure is generated by the pressure springs tipping over when closing, but this results in hard balancing of the door leaf.

In der DD-PS 230893 wird eine luftdicht schließende Schiebetür mit Anpreßdruck beschrieben, bei der das Türblatt circa zur Hälfte von einem auf einer Laufschiene mitrollenden Kipphebel und zur anderen Hälfte von einer separaten, gelenkig gelagerten Hubfeder zwischen Laufrollengehänge und einem Zwischenzahnrad der Betätigungseinrichtung hochgehalten wird. Der horizontale Anpreßdruck wird durch das Überkippen der Hubfeder beim Schließen erzeugt, was jedoch ein hartes Einwuchten des Türblattes zur Folge hat.DD-PS 230893 describes an airtight sliding door with contact pressure, in which the door leaf is held up about half by a rocker arm that rolls on a running rail and the other half by a separate, articulated lifting spring between the roller hanger and an idler gear of the actuating device. The horizontal contact pressure is generated by tilting the lift spring when closing, which however results in hard balancing of the door leaf.

In der FR-A-1 451 538 ist eine Schiebetür beschrieben, die an einer feststehenden Achse mittels Kurbelstangen und einer weiteren Achse aufgehängt ist. Die feststehende Achse steht in Verbindung mit einem in einer Laufschiene geführten Laufrollengehänge. Über eine bewegliche Nockenscheibe wird bei Betätigung eines inneren oder äußeren Griffes ein Gestänge und damit auch die Schiebetür nach oben oder unten bewegt, je nachdem, in welche Richtung eine Rolle, die von einer Feder an die Nockenbahn gedrückt wird, an der Nockenscheibe entlanggleitet.FR-A-1 451 538 describes a sliding door which is suspended on a fixed axis by means of crank rods and a further axis. The fixed axis is connected to a roller hanger guided in a running rail. A linkage and thus also the sliding door is moved upwards or downwards via a movable cam disc when an inner or outer handle is actuated, depending on the direction in which a roller that is pressed against the cam track by a spring slides along the cam disc.

Die Aufgabe der Erfindung besteht ausgehend von einer Schiebetür der eingangs genannten Art darin, die Nachteile der beschriebenen Schiebetüren mit hochhaltenden Druckfedern auszuschalten und um einige Vorteile zu erweitern, wobei insbesondere der Betätigungsablauf von Schließen und Senken bzw. Heben und Öffnen so harmonisiert werden soll, daß die Türen in Verschlußstellung weich und selbsttätig zufallen und dadurch ein einfache Motorisierung sowie der Einsatz als Selbstschließanlage ermöglicht wird. Dabei soll der Verschleiß des Dichtgummis reduziert werden.The object of the invention is based on a sliding door of the type mentioned is to eliminate the disadvantages of the sliding doors described with high-pressure springs and to expand some advantages, in particular the operation of closing and lowering or lifting and opening should be harmonized so that the doors close softly and automatically in the locked position, thereby enabling simple motorization and use as a self-locking system. The wear on the rubber seal should be reduced.

Zur Lösung der Erfindungsaufgabe ist die Schiebetür gemäß Anspruch 1 gekennzeichnet. Das Türblatt ist an Nocken einer Tragwelle aufgehängt wobei die Nocken von der Tragwelle horizontal nach außen stehen und in dieser Stellung die Nocken von einer oder mehreren Druckfedern mit der Kraftkompression von 3/4 bis 2/3 des Türblattgewichtes abgestützt werden. Die restliche Hochhaltekraft übernimmt ein auf der Laufschiene mitrollender Kipphebel.To solve the problem of the invention, the sliding door is characterized according to claim 1. The door leaf is suspended on cams of a support shaft, the cams standing horizontally outwards from the support shaft and in this position the cams are supported by one or more compression springs with the force compression of 3/4 to 2/3 of the door leaf weight. The remaining hold-up force is taken over by a rocker arm that rolls on the running rail.

Die Abstützung dieser Hochhaltedruckfeder erfolgt so, daß sie mittels kippbaren Gelenken von der stabil gelagerten Tragwelle kraftschlüssig auf die abstehenden Nocken einer vorgelagerten Nockenwelle wirken und dieser Kraftanteil über die rückwirkenden Schubstangen auf die Nocken der Tragwelle und dem hier angehängten Türblattgewicht entgegendrückt.This high-pressure spring is supported in such a way that it acts by means of tiltable joints from the stably mounted support shaft on the protruding cams of an upstream camshaft and this force component presses against the cams of the support shaft and the door leaf weight attached here via the retroactive push rods.

Nach einer bevorzugten im Anspruch 2 gekennzeichneten Ausführungsart der Erfindung beträgt der radiale Abstand der Schubstangengelenke an der Nockenwelle ca. das 1,5 bis 2 fache des Abstandes an der Tragwelle, was eine Reduzierung der Verdrehungswinkel für die Betätigung von ca. 90° der Tragwelle auf ca. 45° der Nockenwelle ermöglicht. Hierbei bleibt die Kompressionskraft der Druckfedern beim Ausschwenken der Federgelenke aus der Flucht Tragwelle-Nokkenwelle weitgehende erhalten bzw. entsteht durch den sich ausbildenden Kraftabstand zur Drehachse der Nockenwelle in Verbindung mit Dimensions und Vorspannung der Druckfedern die anteilige genügende Hochhaltekraft. Für den Anpreßdruck des Türblattes in der oberen Horizontalen werden entsprechend der Merkmalen des Anspruchs 3 separate Anpreßfedern zwischen Tragwelle und Nockenwelle angeordnet, die wie die Hochhaltefedern einerseits auf der Tragwelle und andererseits auf der Nockenwelle lagern, jedoch um den Verdrehungsbereich von ca. 45° nach unten versetzt angelenkt sind. Die Anpreßfedern erreichen ihre maximale Kraftwirkung dann, wenn die Hochhaltedruckfedern ihre Kraftwirkung aufheben. In der Hochlage ist dies genau umgekehrt. Damit steht jeweils der Anpreßdruck dem Hochhaltedruck entgegen, einer von beiden wird aber auf Grund des von 0° auf 45° wechselnden Abstand in den Endstellungen neutralisiert bzw. gespeichert, während der andere sein Maximum erreicht.According to a preferred embodiment of the invention characterized in claim 2, the radial distance of the push rod joints on the camshaft is approximately 1.5 to 2 times the distance on the support shaft, which reduces the angle of rotation for the actuation of approximately 90 ° of the support shaft approx. 45 ° of the camshaft. The compression force of the compression springs remains when the spring joints are swiveled out of the alignment shaft-nok kenwelle largely receive or arise from the developing force distance to the axis of rotation of the camshaft in connection with dimensions and preload of the compression springs, the proportionate sufficient holding force. For the contact pressure of the door leaf in the upper horizontal, according to the features of claim 3, separate contact springs are arranged between the support shaft and the camshaft, which, like the holding springs, support the support shaft on the one hand and the camshaft on the other hand, but by a rotation range of approx. 45 ° downwards are articulated offset. The contact springs reach their maximum force when the high pressure springs cancel their force. In the high position, this is exactly the opposite. This means that the contact pressure opposes the holding pressure, but one of the two is neutralized or stored in the end positions due to the distance changing from 0 ° to 45 °, while the other reaches its maximum.

Durch die Anordnung von zweierlei Federn kann der Hochhalte- und der Anpreßdruck in günstiger Weise unabhängig voneinander gespannt und eingestellt werden. Beim Drehen der Nockenwelle mittels der Betätigungseinrichtung in die Hochhaltung der Tür wird der Kraftwirkungsabstand der Hochhaltedruckfeder zur Drehachse der Nockenwelle schnell vergrößert und die vorgespannte Federkraft bewirkt etwa zu 3/4 bis 2/3 das Ausheben des Türblattes. Das Hochhaltende Restgewicht trägt der bereits genannte, auf der Laufschiene mitrollende und im verschlußseitigen Laufrollengehänge gelagerte Krafthebel. Der dazugehörige Lastarm hat zu dem Kraftarm ein Verhältnis von ca. 1:4 bis 1:8 und an ihm ist über ein Gleitlager sowohl das Türblatt mit seinem Restgewicht als auch die Hebelbetätigungseinrichtung angelenkt. Die Last-Kraftarmumsetzung von 1:4 bis 1:8 verursacht von dem noch belassenen Restgewicht einen sehr geringen Rollendruck, der beim Schieben kaum bemerkbar ist.The arrangement of two springs enables the holding and contact pressure to be tensioned and adjusted independently of one another in a favorable manner. When the camshaft is turned into the upright position of the door by means of the actuating device, the force action distance of the hold-up pressure spring to the axis of rotation of the camshaft is quickly increased and the pretensioned spring force causes the door leaf to be lifted by about 3/4 to 2/3. The holding residual weight is borne by the already mentioned power lever, which rolls on the running rail and is mounted in the lock-side running gear suspension. The associated load arm has a ratio of approx. 1: 4 to 1: 8 to the power arm and both the door leaf with its residual weight and the lever actuation device are articulated to it via a slide bearing. The load-force conversion from 1: 4 to 1: 8 causes a very low roller pressure from the remaining weight, which is hardly noticeable when pushing.

Erst in den Verschlußstellung, d.h. am Ende der Laufschiene kann dieser Kraftarm nach unten ausweichen und das Türblatt fällt nunmehr mit dem geringen Restgewicht nach unten. Das die andere Hochhaltekraft der Hochhaltefeder noch mit- bzw. entgegenwirkt, entsteht ein weiches Einfallen des Türblattes. Die Kraftaufteilung zwischen Hochhaltefeder und Kipphebel kann durch Spannen der Hochhaltefeder je nach den Erfordernissen variiert werden.Only in the closed position, i.e. At the end of the track, this arm can move downwards and the door leaf now falls down with the low residual weight. The other hold-up force of the hold-up spring also acts or counteracts the door leaf falling in softly. The force distribution between the holding spring and the rocker arm can be varied by tensioning the holding spring according to the requirements.

Das Absenken des mitrollenden Krafthebels erfolgt an einem am Ende der Laufschiene angebrachten Sperrbogen. Dieser Sperrbogen verhindert außerdem beim Ausheben mittels der Betätigungseinrichtung ein vorzeitiges Wegschieben.The rolling power lever is lowered on a locking elbow attached to the end of the running rail. This locking bow also prevents premature pushing away when lifting by means of the actuating device.

Die Kraftaufwendung für die Betätigung ist insgesamt geringer wie für Schiebetüren ähnlicher Bauart, da die eingestellten Federkräft immer erhalten bleiben. Die kraftübertragenden Betätigungshebel und Notöffnungshebel sind am Türblatt immer wie außen so angeordnet, daß deren Betätigung jeweils in gleicher Richtung zum Schieben erfolgt, wobei das Kraftübertragungsverhältnis so gewählt ist, daß das Öffnen um einen geringen Mehrdruck wie das Schieben benötigt. Damit entsteht die gewollte zusammengefaßte leichte Einhandbetätigung.The effort required for actuation is lower overall than for sliding doors of a similar design, since the set spring force is always retained. The force-transmitting actuating lever and emergency opening lever are always arranged on the door leaf as well as outside so that they are actuated in the same direction for pushing, the power transmission ratio being selected so that opening requires a little more pressure than pushing. This creates the desired, summarized, easy one-hand operation.

Die erfindungsgemäße Schiebetür ist entsprechend der Merkmalen des Anspruchs 4 des weiteren gekennzeichnet durch einen zusätzlichen und gegenüber der manuellen Betätigungseinrichtung angeordneten zweiten nach oben stehenden Motorbetätigungshebel, der motorisch mit einem Zugseil oder einer Kette betätigt wird. Der nach oben stehende Motorbetätigungshebel ist auf einer Achswelle am Türkoffer gelagert, wobei dessen Kraftarm von einem Zugseil oder einer Kette nach dem Zufahren oder vor dem Auffahren in dieser Richtung weiterbewegt wird, wodurch der rechtwinklig abgebogene Lastarm über ein Zwischengelenk und eine oben an der Nockenwelle angelenkte Hubstange die Nockenwelle und damit auch die Tragwelle in Verschluß- oder Offenstellung verdreht.The sliding door according to the invention is further characterized in accordance with the features of claim 4 by an additional and opposite to the manual actuating device arranged second upstanding motor operating lever, which is operated by a motor with a pull rope or a chain. The upright engine operating lever is mounted on an axle shaft on the door case, the power arm of which is moved in this direction by a pull rope or chain after closing or before opening, whereby the right-angled load arm is articulated via an intermediate joint and an articulated arm on the top of the camshaft Lift rod rotates the camshaft and thus also the support shaft in the closed or open position.

Aufgrund der spiegelbildlich eingreifenden Kraftwirkung des Motorbetätigungshebels im gegenüberliegenden Laufrollengehänge ergibt sich auch hier wieder in günstiger Weise ein synchronisierter Ablauf von Schieben und Schließen bzw. Öffnen und Schieben und damit eine sehr einfache motorische Schaltung zwischen zwei Endschaltern, wobei zur Verhinderung des Einklemmens von Personen oder Fahrzeugen und zur Gewährleistung sicherheitstechnischer Belange zusätzlich ein Notaufschalter zwischen dem Seil oder der Kette und dem Motorbetätigungshebel in Kombination mit einer Druckfeder eingebunden ist und während des Zufahrens alle Steuerbefehle auf Auffahren geschaltet sind.Due to the mirror-image intervening force of the motor operating lever in the opposite roller hanger, a synchronized sequence of pushing and closing or opening and pushing results again in a favorable manner and thus a very simple motorized connection between two limit switches, thereby preventing people or vehicles from getting caught and to ensure safety-related matters, an emergency switch is additionally integrated between the rope or chain and the engine operating lever in combination with a compression spring and all control commands are switched to opening while the vehicle is closing.

In einer günstigen Ausführungsform der Erfindung gemäß den in den Ansprüchen 5 und 6 angegebenen Merkmalen ist zusätzlich zur Handbetätigung auf Grund der sehr leichten Schiebekraft der Anbau einer zeitverzögerten Selbstschließanlage vorgesehen. Dabei wird an dem verschlußseitigen Laufrollengehänge ein Rückzugseil angeklemmt, welches auf einer Seiltrommel aufgewickelt und freigegeben wird. Die Seiltrommel wird ihrerseits durch ein aufgespultes Zugseil mit einem aufgehängten Gewicht oder einer Zugfeder immer in Verschlußdrehrichtung gezogen. Mit dem Aufschieben wird diese Rückzugskraft zunächst mit überwunden und gleichzeitig durch eine Sperrklinke an der Seiltrommel geben sofortiges Wiederzurollen des Türblattes gesichert. Mittels eines einstellbaren elektrischen Zeitrelais mit einem Schaltbereich von etwa 0 bis 300 sek. und eines nachgeschalteten Kurzhubmagnetes wird über eine Verbindungsstange nach Ablauf der eingestellten Offenhaltezeit die Sperrklinke aus der Arretierung gelöst und das Türblatt wird durch Gewicht oder Zugfeder in die Verschlußstellung gezogen, wo es durch das erfindungsgemäße System selbsttätig in den Verschluß fällt. Das diesen Vorgang bewirkende Gewicht besteht aus aneinandergekoppelten Teilgewichten, die nur in ganz offenem Zustand alle vom Boden angehoben sind und einen sicheren Anlauf nach der Sperrklinkenauslösung gewährleisten. Dabei wird in günstiger Weise der nach dem Ausheben des Türblattes zum Anschieben aus der Ruhelage etwas größere Kraftbedarf nicht noch zusätzlich mit dem vollen, sondern nur mit einem geringen Teilgewicht erhöht.In a favorable embodiment of the invention according to the features specified in claims 5 and 6, in addition to manual operation, the installation of a time-delayed self-locking system is provided due to the very slight pushing force. In this case, a retraction cable is clamped to the lock-side roller suspension, which is wound up on a cable drum and released. For its part, the rope drum is always pulled in the direction of lock rotation by a coiled pull rope with a suspended weight or a tension spring. By pushing this retraction force is overcome at the same time and at the same time a locking pawl on the cable drum ensures that the door leaf rolls back immediately. By means of an adjustable electrical time relay with a switching range of approximately 0 to 300 seconds. and a downstream short-stroke magnet, the pawl is released from the locking device via a connecting rod after the set hold-open time has elapsed, and the door leaf is pulled into the locked position by weight or tension spring, where it falls automatically into the lock due to the system according to the invention. The weight causing this process consists of a part coupled together weights that are only lifted off the floor when fully open and ensure a safe start after the pawl is released. In this case, the somewhat greater power requirement after lifting the door leaf to push it out of the rest position is not additionally increased with the full, but only with a low partial weight.

Durch die Erfindung, insbesondere durch die Gesamtkonzeption der radialen Türblattabsenkung von horizontal außen nach senkrecht unten entsteht ein fast horizontales Anschlagen des Türblattes, welches mit den bisher bekannten Lösungen nicht realisierbar war. Dadurch entfällt bis auf die zwei unteren Ecken die den Verschleiß fördernde Dichtgummireibung, so daß ein Weichgummiprofil wie z.B. Magnetbandprofil aus dem Kühlschrankbau verwendet werden kann. Die untere Führung und Anpressung des Türblattes erfolgt außen in an sich bekannter Weise mittels eines Führungseisens, welches nach unten eine verstellbare Schrägfläche zum Einrutschen des Türblattes beim Absenken besitzt. Innenseitig erfolgt die Führung an einem über die Türbreite angebrachten und über dem Magnetprofilband erhöhten Stahlprofil, welches nur in der Verschlußstellung durch Abflachung das Absenken des Türblattes an dem Rahmen ermöglicht.The invention, in particular the overall concept of the radial door leaf lowering from horizontally outside to vertically below, results in the door leaf striking almost horizontally, which was not possible with the previously known solutions. Apart from the two lower corners, this eliminates the rubber seal that encourages wear, so that a soft rubber profile such as Magnetic tape profile from refrigerator construction can be used. The lower guiding and pressing of the door leaf takes place on the outside in a manner known per se by means of a guide iron which has an adjustable inclined surface at the bottom for the sliding of the door leaf when lowering. The inside is guided on a steel profile attached over the door width and raised above the magnetic profile band, which only allows the door leaf to be lowered on the frame by flattening in the closed position.

Anhand eines angebildeten Ausführungsbeispieles wird die Erfindung im folgenden näher erläutert: Es zeigenThe invention is explained in more detail below on the basis of an illustrated exemplary embodiment: It shows

An einer Laufschiene 2 aus zwei verbundenen Winkelstählen sind zwei Laufrollengehänge 3 außenseitig am Türblatt 1 aufgehängt. Um Bauhöhe einzusparen, sind die Laufrollen 4 innerhalb des U-förmigen Verbundprofiles der Laufschiene 2 angeordnet. Durch die Führungsrollen 5 sind die Laufrollengehänge 3 stabil gelagert.Two roller hangers 3 are suspended on the outside of the door leaf 1 on a running rail 2 made of two connected angle steels. To save overall height, the rollers 4 are arranged within the U-shaped composite profile of the rail 2. The roller hangers 3 are stably supported by the guide rollers 5.

Die Laufrollengehänge 3 bestehen aus zwei seitlichen senkrechten Laufrollenstegblechen 6 und einer quer verbindenden Laufgrundplatte 7. In die Stegbleche 6 sind innenseitig die Tragwellenlager 8 zur Aufnahme der Tragwelle 9 und außenseitig die Nockenwellenlager 10 der Nokkenwelle 11 angeordnet. An die Tragwelle 9 sind mittig zwei Aufhängenocken 12 angeschweißt, die zwei Lagerbohrungen besitzen.The roller hangers 3 consist of two lateral vertical roller web plates 6 and a transversely connecting running base plate 7. In the web plates 6, the support shaft bearings 8 for receiving the support shaft 9 are arranged on the inside and the camshaft bearings 10 of the camshaft 11 on the outside. Two suspension cams 12 which have two bearing bores are welded to the center of the support shaft 9.

Die in Verschlußstellung nach unten stehende Bohrung dient als Aufhängegelenk 13 des verstellbaren Aufhängebügels 14, an dem das Türblatt 1 aufgehängt ist. Die um 45° nach dem Türrahmen 15 zu versetzt vorgesehene Bohrung dient als Schubstangengelenk I 16 zur Anlenkung einer kraftübertragenden Schubstange 17. Das andere Ende dieser Schubstange 17 ist am Schubstangengelenk II 18 der Nockenscheibe 19 an der vorgelagerten Nockenwelle 11 angelenkt. Der Abstand des Schubstangengelenkes 1118 zur Nokkenwellenachse steht dabei im Verhältnis von ca. 1:2. Damit entsteht aus der ca. 90°-Verdrehung der Tragewelle 9 eine um 45°-Verdrehung der Nockenwelle 11. Zwischen der Tragwelle 9 und der Nockenscheibe 19 der Nockenwelle 11 werden kräftige Hochhaltedruckfedern 20 und Anpreßfedern 21 mit kippbaren Federanschlußgelenken 22 eingebaut.The downward bore in the closed position serves as a suspension joint 13 of the adjustable suspension bracket 14, on which the door leaf 1 is suspended. The 45 ° offset to the door frame 15 provided bore serves as a push rod joint I 16 for articulating a force-transmitting push rod 17. The other end of this push rod 17 is articulated on the push rod joint II 18 of the cam disk 19 on the upstream camshaft 11. The distance between the push rod joint 1118 and the camshaft axis is approximately 1: 2. This results from the approximately 90 ° rotation of the support shaft 9 by a 45 ° rotation of the camshaft 11. Between the support shaft 9 and the cam disk 19 of the camshaft 11, strong holding pressure springs 20 and pressure springs 21 with tiltable spring connection joints 22 are installed.

Je nach Stellung der Nockenwelle 11 bzw. dem Abstand der Kraftwirkung zur Drehachse der Nokkenwelle 11 wechseln die Federkräfte jeweils zwischen einem Maximum und Null. In Verschlußstellung des Türblattes 1 liegen die Federanschlußgelenke 22 der Hochhaltedruckfedern 20 in Flucht mit den Achsen der Tragwelle 9 und der Nockenwelle 11, so daß die Kraftwirkung der Hochhaltedruckfeder 20 in dieser Stellung aufgehoben ist. Die um ca. 45° an der Nockenscheibe 19 versetzt angelenkten Anpreßfedern 21 haben hingegen ihr Maximum erreicht und bewirken ein Anpressen des Türblattes 1. In der Offenstellung des Türblattes 1 dagegen erreicht die Kraftwirkung der Hochhaltedruckfedern 20 ihr Maximum mit etwa 2/3 bis 3/4 des Türblattgewichtes. Für die Hochhaltung des Rest gewichtes von 1/4 bis 1/3 des Türblattes 1 ist in dem verschlußseitigen Laufrollengehänge 3 ein Kipphebel 23 gelagert, dessen Lastarm 24 diesen Gewichtsanteil über ein Gleitlager 25 und eine Hubstange 26 von der Nockenscheibe 19 der Nockenwelle 11 aufnimmt und über den Kraftarm 27 mittels einer Rolle 28 als Druckkraft auf die Laufschiene 2 überträgt. Dabei bewirkt die Lastarm-Kraftarmumsetzung des mitrollenden Kipphebels 23 von 1:4 bis 1:8 einen sehr geringen Rollendruck.Depending on the position of the camshaft 11 or the distance of the force effect from the axis of rotation of the camshaft 11, the spring forces alternate between a maximum and zero. In the closed position of the door leaf 1, the spring connection joints 22 of the holding pressure springs 20 are in alignment with the axes of the support shaft 9 and the camshaft 11, so that the force of the holding pressure spring 20 is canceled in this position. The pressure springs 21, which are articulated by approximately 45 ° on the cam disk 19, on the other hand, have reached their maximum and cause the door leaf 1 to be pressed against them. In the open position of the door leaf 1, on the other hand, the force of the holding pressure springs 20 reaches its maximum with approximately 2/3 to 3 / 4 of the door leaf weight. For maintaining the rest of the weight of 1/4 to 1/3 of the door leaf 1, a rocker arm 23 is mounted in the lock-side roller hanger 3, the load arm 24 of which takes up this proportion by weight via a slide bearing 25 and a lifting rod 26 from the cam disk 19 of the camshaft 11 and transmits via the power arm 27 by means of a roller 28 as a compressive force on the running rail 2. The load arm force arm conversion of the rolling rocker arm 23 from 1: 4 to 1: 8 causes a very low roller pressure.

In der Verschlußstellung des Türblattes 1 hat die Rolle 28 des Kraftarmes 27 das Ende der Laufschiene 2 erreicht und kann hier mit diesem geringen Restgewicht über einen Senkbogen 29 nach unten ausweichen. Der Senkbogen 29 verhindert gleichzeitig ein vorzeitiges Aufschieben des Türblattes 1 beim Ausheben desselben. Das Ausheben des Türblattes 1 erfolgt durch innen-und außenseitig am Türblatt 1 angeordnete Handbetätigungshebel 30 bzw. Notöffnungshebel 31, deren Kraftwirkung richtungsgleich mit der jeweiligen Schieberichtung ist. Über ein Hubgelenk 32 der Hubstange 26 am Ende des Lastarmes 24, des Kipphebels 23 und eines Gleitlagers 25 wird die Betätigungskraft auf die Nockenscheibe 19 der Nockenwelle 11 und auch auf den Kipphebel 23 übertragen, so daß der Kraftarm 27 mit seiner Rolle 28 ebenso wie das Türblatt 1 ausgehoben oder gesenkt werden kann.In the closed position of the door leaf 1, the roller 28 of the power arm 27 has reached the end of the running rail 2 and, with this low residual weight, can dodge downwards via a countersunk arch 29. The countersunk arch 29 simultaneously prevents the door leaf 1 from being pushed open prematurely when the latter is lifted out. The door leaf 1 is lifted out by means of manual actuation lever 30 or emergency opening lever 31 arranged on the inside and outside of the door leaf 1, the force effect of which is in the same direction as the respective sliding direction. About a lifting joint 32 of the lifting rod 26 at the end of the load arm 24, the rocker arm 23 and a slide bearing 25, the actuating force is transmitted to the cam plate 19 of the camshaft 11 and also to the rocker arm 23, so that the power arm 27 with its roller 28 as well as that Door leaf 1 can be raised or lowered.

Die untere Führung und Anpressung des Türblattes 1 erfolgt in an sich bekannter Weise mittels eines Führungseisens 35, welches nach unten eine verstellbare Schrägfläche zum Einrutschen des Türblattes 1 beim Absenken besitzt.The lower guiding and pressing of the door leaf 1 takes place in a manner known per se by means of a guide iron 35 which has an adjustable inclined surface at the bottom for the sliding of the door leaf 1 when lowering.

Wie in Figur 4 dargestellt, kann zusätzlich zum manuellen Handbetätigungshebel 30 oder auch selbständig ohne denselben für eine Betätigung mit Motor 33 im entgegengesetzten Laufrollengehänge 3 ein nach oben stehender Motorbetätigungshebel 36 angeordnet werden, der motorische mit einem Zugseil 37 oder einer Kette 37 bewegt wird. Wie ersichtlich, ergibt sich auch hier wieder unter der Zwischenschaltung eines Hubgelenkes 32, einer Hubstange 26 und der Nockenscheibe 19 der Nockenwelle 11 wie vor beschrieben ein synchroner Ablauf von Schieben und Schließen bzw. Öffnen und Schieben und damit auch eine sehr einfache motorische Schaltanlage 34. Die Mitnahme des Motorbetätigungshebel 36 durch gas Zugseil 37 oder die Kette 37 erfolgt sicherheitstechnisch über eine Sicherheitsfeder 38, die ab einer einstellbaren Belastung bzw. Kompressions mechanisch einen zwischen der Ankopplung angeordneten Notaufschalter 39 betätigt, so daß bei Einklemmen von Personen oder Fahrzeugen das Türblatt 1 sofort wieder auffährt. Die erhöhte Anschubkraft aus der Ruhelage wird diesbezüglich durch eine entsprechende Schaltung zwischen dem Aufschalter I 40 und dem Aufschalter II 41, die etwa 20 cm Abstand haben, überbrückt. Die Notaufschaltung erfolgt also erste nach dem etwa 20 cm-Anlauf.As shown in FIG. 4, in addition to the manual manual actuation lever 30 or also independently without the same for an actuation with motor 33 in the opposite roller linkage 3, an upstanding motor operating lever 36 can be arranged, which is moved motorically with a pull rope 37 or a chain 37. As can be seen, the interposition of a lifting joint 32, a lifting rod 26 and the cam disk 19 of the camshaft 11 results in a synchronous sequence of pushing and closing or opening and pushing and thus also a very simple motorized switchgear assembly 34. The entrainment of the motor operating lever 36 by gas pull cable 37 or the chain 37 takes place safety-related via a safety spring 38, which mechanically actuates an emergency stop switch 39 arranged between the coupling as of an adjustable load or compression, so that when people or vehicles are caught, the door leaf 1 immediately opens again. The increased pushing force from the rest position is bridged in this regard by a corresponding circuit between the switch I 40 and the switch II 41, which are about 20 cm apart. The emergency cut-in therefore takes place first after the approximately 20 cm start-up.

In Figur 5 ist eine Ergänzung der manuellen Betätigung durch eine zeitverzögerte Selbstschließanlage dargestellt. In Höhe der Laufschiene 2 ist am verschlußseitigen. Laufrollengehänge 3 ein Rückzugseil 42 angeklemmt, das von einer seitliche angeordneten Seiltrommel 43 aufgerollt oder freigegeben wird. Die Seiltrommel 43 wird ihrerseits durch ein aufgespultes Zugseil 44 mit einem angekoppelten Gewicht 45 oder einer Zugfeder 46 immer in Verschlußdrehrichtung gezogen, sofern dies nicht verhindert wird. Zur Erreichung einer Zeitverzögerung für den Türdurchgang ist seitlich an der Seiltrommel 43 eine Sperrklinke 47 angebracht, die nach Ablauf einer eingestellten Zeit an einem elektronischen Zeitrelais 48 mittels einer Verbindungsstange 49 und eines Kurzhubmagnetes 50 gelöst wird. Danach wird das Türblatt 1 durch das Gewicht 45 oder einer Feder 46 in Verschlußstellung gezogen, wo es durch das eingangs beschriebene System selbsttätig in den Verschluß fällt. Die Zugkraft besteht dabei aus aneinandergekoppelten Teilgewichten 51, die nur in ganz offenem Zustand alle vom Boden angehoben sind, und einen sicheren Anlauf nach der Sperrklinkenauslösung gewährleisten, Andererseits wird die erhöhte Anschubkraft aus der Ruhelage nicht sofort mit dem vollen, sondern nur um ein Teilgewicht 51 erhöht.FIG. 5 shows a supplement to the manual actuation by a time-delayed self-locking system. At the level of the track 2 is on the lock side. Roller suspension 3 clamped a retraction cable 42 which is rolled up or released by a cable drum 43 arranged on the side. The cable drum 43 is in turn always pulled in the direction of closure rotation by a spooled pull rope 44 with a coupled weight 45 or a tension spring 46, unless this is prevented. In order to achieve a time delay for the door passage, a pawl 47 is attached to the side of the cable drum 43, which is released on an electronic time relay 48 by means of a connecting rod 49 and a short-stroke magnet 50 after a set time. Then the door leaf 1 is pulled by the weight 45 or a spring 46 into the closed position, where it falls automatically into the lock due to the system described at the beginning. The tractive force consists of coupled partial weights 51, all of which are only raised from the ground in the fully open state, and ensure a safe start after the pawl has been released elevated.

Das gleiche gilt für die Anordnung einer oder mehrerer Zugfedern 46.The same applies to the arrangement of one or more tension springs 46.

Airtight closing sliding door according to claim 1 and 2, characterised in that the upper horizontal pressure against the door leaf (1) is effected by means of one or more separate pressure springs (21), which, like the upholding pressure springs (22), rest on the supporting shaft (9) on the one hand and against the cam shaft (11) on the other, in the twisting region however, they are connected downwardly displaced by approximately 45°, so that although the contact pressure counteracts the upholding pressure, in the end positions, however, as a result of the clearance having changed from 0 to approximately 45°, one of the two respectively is neutralised or stored and the other one respectively reaches its maximum.
4. Airtight closing sliding door according to claim 1 to 3, characterised in that in addition to and opposite to the manual operating device, there may be arranged a second one which is operated by a motor in such a way that the power arm of an upwardly positioned motor operating lever (36), which is mounted on an axle shaft of the door leaf (1), after travel in the closure direction or before travel in the open position, is moved further in this direction by a chain (37) or a traction cable (37) which, through a lifting linkage (32) and a lifting bar (26) connected at the top of the cam shaft (11), causes the rectangularly offset load arm together with the lifting bar (26) and therefore also the supporting shaft (9) to be twisted into the closure or open position.
5. Airtight closing sliding door according to claim 1 to 3, characterised in that additionally to the manual operation of a delayed self-closing installation it is possible to add on in such a way that a pull-back cable (42) secured to the suspended roller (3) is rolled up or released by a cable drum (43), this cable drum (43) itself always being rotated in the closure direction through a second traction cable (44) wound onto the cable drum (43) by means of a suspended weight (45) or a wound up traction spring (46), when being pushed open however this cable is initially blocked by a ratchet (47) which, only after an adjustable time has elapsed, is released by a time relay (48) via a short-stroke magnet (50) and a connecting rod (49) so as to trigger the door closing operation.
6. Airtight closing sliding door according to claim 5, characterised in that the suspended weight (46) for the self-closing operation consists of a number of loosely connected individual weights (51), which only lift off the floor successively one at a time.
