Sektionalhub- oder Falttore sind seit langem bekannt und gebräuchlich. Sie sind aus lamellenartigen, im wesentlichen rechteckig plattenförmi- gen Sektionen zusammengesetzt, wobei zwei vertikal benachbarte Sek- tionen entlang einer gemeinsamen, horizontalen Schwenkachse, die parallel zu den Längsseiten der Sektionen verläuft, relativ zueinander verschwenkbar sind. Als Material für die Sektionen wird u. a. Leichtmetall wie z. B. Aluminium verwendet. Man unterscheidet dabei Hubtore, bei denen während des Anhebens die Sektionen im wesentlichen um 90° verschwenkt werden und im geöffneten Zustand das Tor parallel zur Decke verläuft, und Falttore, bei denen die benachbarten Sektionen während des Öffnens leporelloartig zusammengefaltet werden. Diese Tore werden dazu verwendet, um großflächige Öffnungen in Gebäuden, beispielsweise Garagen- oder Industrietore verschließen zu kön- nen, ohne dass weit ausschwenkende starre Türflügel verwendet werden.Sectional or folding gates have long been known and in use. They are composed of lamellar, essentially rectangular, plate-shaped sections, two vertically adjacent sections being pivotable relative to one another along a common, horizontal pivot axis which runs parallel to the long sides of the sections. As material for the sections u. a. Light metal such. B. aluminum used. A distinction is made between lifting gates, in which the sections are pivoted by 90 ° during lifting and the gate runs parallel to the ceiling when open, and folding gates, in which the adjacent sections are folded up like a leporello during opening. These gates are used to be able to close large openings in buildings, for example garage or industrial gates, without the use of rigid door wings that swing out far.
Um das Passieren des Tores für eine Einzelperson zu ermöglichen, ohne das gesamte Tor öffnen zu müssen, ist es bekannt, Türen in diese Tore zu integrieren, wobei das Türblatt ebenfalls aus mehreren relativ zueinander verschwenkbaren Sektionen zusammengesetzt ist, und die Schwenkachsen dieser Türblattsektionen koaxial zu den oben beschriebenen Schwenkachsen verlaufen. Die Tür ist zur Erhöhung der Stabilität der Konstruktion in einem aus vertikal und horizontal verlaufenden Zargen bestehenden Türrahmen eingesetzt. Diese Türen sollten auch als Fluchttüren, beispielsweise im Falle eines Brandes, verwendet werden können, wenn sich das Tor auf übliche Weise nicht mehr öffnen lässt.In order to allow an individual to pass through the gate without having to open the entire gate, it is known to have doors in it To integrate gates, the door leaf also being composed of a plurality of sections which can be pivoted relative to one another, and the pivot axes of these door leaf sections run coaxially with the pivot axes described above. The door is used to increase the stability of the construction in a door frame consisting of vertically and horizontally running frames. These doors should also be able to be used as escape doors, for example in the event of a fire, if the door can no longer be opened in the usual way.
Als Nachteil bei den bisher bekannten Toren mit einer integrierten Tür ist anzusehen, dass an der Unterseite der Türen immer eine horizontal verlaufende Zarge bzw. Schwelle angeordnet ist, die besonders in Notfällen, in denen ein rasches Verlassen des Gebäudes notwendig ist, eine Stolperschwelle darstellt, über die Personen stürzen und sich verletzen können bzw. die Evakuierung des Gebäudes verzögert wird. Diese Schwelle wird bisher als unerlässlich angesehen, da sie einerseits dazu dient der gesamten Torkonstruktion im geschlossenen Zustand eine hinreichende Stabilität zu verleihen und andererseits ver- mieden wird, dass beim Öffnen des Tores eine Verwindung der bodenseitigen Sektion senkrecht zur Hauptebene des Tores auftritt. Auch wird bei formschlüssigem Kontakt des Türblatts mit diesem stabilen, um die Türöffnung umlaufenden Türrahmen verhindert, dass sich die verschwenkbaren Sektionen des Türblatts relativ zum Tor bewegen. Diese Schwelle ist auch der Grund dafür, dass derartige Türen nicht alsA disadvantage of the hitherto known gates with an integrated door is that a horizontally running frame or threshold is always arranged on the underside of the doors, which represents a trip hazard, particularly in emergencies in which a quick exit from the building is necessary, over which people can fall and injure themselves or the evacuation of the building is delayed. This threshold has so far been regarded as indispensable because on the one hand it serves to give the entire door structure sufficient stability when closed and on the other hand it prevents the bottom section from twisting perpendicular to the main plane of the door when the door is opened. Also, if the door leaf comes into positive contact with the stable door frame surrounding the door opening, the pivotable sections of the door leaf are prevented from moving relative to the door. This threshold is also the reason why such doors are not considered

Ausgehend vom Stand der Technik hat sich die Erfindung zur Aufgabe gestellt, ein Hub- oder Falttor mit einer Türe derart zu gestalten, dass die bodenseitige, horizontal verlaufende Schwelle unterhalb des Türblattes entfallen kann, ohne dass die konstruktive Stabilität des Tores beeinträchtigt wird, sowie eine Verwindung der Torsektionen bzw. eine Relativbewegung des Türblattes zum Tor während des Öffnens nicht auftritt.Starting from the prior art, the invention has set itself the task of designing a lifting or folding door with a door such that the bottom-side, horizontally running threshold underneath the door leaf can be omitted without the structural stability of the door being impaired, and the door sections cannot be twisted or the door leaf can move relative to the door during opening.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, dass das Turblatt im geschlossenen Zustand des Tores sich bis zum Boden hin erstreckt, das Türblatt oder die Zarge mit mindestens einer Öffnung versehen ist, mindestens ein Schubbolzen axial, in der Hauptebene des Tores horizontal verschiebbar im bodenseitigen Bereich der Zarge oder des Türblatts angeordnet ist und der Schubbolzen bei geschlossener Tür in die Öffnung eingreift.According to the invention, this object is achieved in that the door leaf extends to the floor in the closed state of the door, the door leaf or the frame is provided with at least one opening, at least one push pin axially, horizontally displaceable in the bottom area of the door in the main plane of the door Frame or the door leaf is arranged and the push pin engages in the opening when the door is closed.
Der Kerngedanke der Erfindung besteht darin, dass das Türblatt mit mindestens einem Schubbolzen und mindestens einem von diesem mitbewegten Riegelelement relativ zur Zarge und damit dem Tor festgelegt wird. Der Schubbolzen ist axial, d. h. entlang seiner Längsachse, in horizontaler Richtung in der Hauptebene des Tores verlaufend ver- schiebbar. Er kann entweder im Türblatt oder in der die Tür umgebenden Zarge angeordnet sein. Zur Festlegung ist eine in der Zarge oder im Türblatt angeordnete Öffnung vorhanden, die mit dem verschiebbaren Schubbolzen korrespondiert, d. h. ihre Tiefe bzw. ihr Durchmesser ist auf die Abmessungen des Schubbolzens abgestimmt. Zur Arretie- rung des Türblattes in geschlossenem Zustand wird der Schubbolzen, der im bodenseitigen Bereich des Türblatts oder der Zarge angeordnet ist, axial verschoben und damit in Eingriff in die Öffnung gebracht, und eine Bewegung des Türblattes bzw. deren bodenseitiger Sektion senkrecht zur Hauptebene des Tores verhindert. Dazu ist der Schubbolzen idealerweise an der den Türangeln gegenüberliegenden Seite des Türblattes angeordnet, an der sich auch Türgriff und -schloß befinden.The main idea of the invention is that the door leaf is fixed with at least one push pin and at least one locking element moved by it relative to the frame and thus the door. The push pin can be moved axially, ie along its longitudinal axis, in the horizontal direction in the main plane of the door. It can be arranged either in the door leaf or in the frame surrounding the door. For fixing, there is an opening arranged in the frame or in the door leaf, which corresponds to the displaceable push pin, ie its depth or its diameter is matched to the dimensions of the push pin. To lock the door leaf in the closed state, the push pin, which is arranged in the bottom area of the door leaf or frame, is axially displaced and thus brought into engagement in the opening, and a movement of the door leaf or its bottom-side section perpendicular to the main plane of the Tores prevented. This is the push pin Ideally arranged on the side of the door leaf opposite the door hinges, on which the door handle and lock are also located.
Der Vorteil der Erfindung besteht darin, dass aufgrund der Erstreckung des Türblattes bis zum Boden hin, d. h. des Fehlens einer potentiellenThe advantage of the invention is that due to the extension of the door leaf to the floor, i. H. the lack of a potential
Stolperfalle in Form einer Türschwelle, diese Tür als Fluchtweg verwendbar ist. Außerdem wird beim Anheben des Tores zumindest die bodenseitige Sektion des Türblattes relativ zur umgebenden Torsektion festgelegt und damit eine Verbindung des Tores bzw. eine Relativbe- wegung des Türblattes zum Tor unterbunden.Trip hazard in the form of a threshold, this door can be used as an escape route. In addition, when the door is lifted, at least the bottom section of the door leaf is fixed relative to the surrounding door section, thus preventing a connection of the door or a relative movement of the door leaf to the door.
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand von Unteransprüchen.Advantageous embodiments of the invention are the subject of dependent claims.
Eine vorteilhafte Weiterentwicklung der Erfindung besteht darin, dass der Schubbolzen beim Verschieben in die Öffnung ein neben der Öffnung angebrachtes, in den Bewegungsquerschnitt des Schubbolzens hineinragendes, schwenkbares Riegelelement (z. B. eine Sperrklinke) zur Seite drückt oder schiebt, wobei dieses mit einem rastenartig aus- gebildeten Ende hinter die Kante einer auch als Widerlager bezeichneten Halteleiste am Tür- oder Torsegment fasst und einrastet. Durch das Verschwenken und anschließende Einrasten des Riegelelementes ist eine Bewegung des Türblattes oder zumindest seiner bodenseitigen Sektion in der Hauptebene des Tores selbst verhindert.An advantageous further development of the invention is that the push pin pushes or pushes to the side when moving into the opening, a pivotable locking element (e.g. a pawl) attached next to the opening and projecting into the movement cross section of the push pin, this with a detent-like trained end grips behind the edge of a retaining strip, also referred to as an abutment, on the door or gate segment and engages. The pivoting and subsequent latching of the locking element prevents movement of the door leaf or at least its bottom section in the main plane of the door itself.
Falls der Schubbolzen im Türblatt angeordnet ist und die dazugehörende Öffnung in der Zarge, dann muß das Riegelelement sich ebenfalls in der Zarge befinden und greift hinter die Halteleiste, die dann am Türblatt angebracht ist. Vorteilhafterweise ist das Türblatt bzw. sind die die Tür umgebenden Zargen mit mehreren der oben beschriebenen Schubbolzen und Rie- gelelemente ausgestattet. Damit kann das Türblatt an mehreren Stellen festgelegt werden, und insbesondere bei einem aus mehreren Sektionen zusammengesetzten Türblatt können die Schubbolzen und Riegelelemente in den seitlichen unteren und/oder oberen Randbereichen der Tür angeordnet werden, um eine Relativbewegung der einzelnen Tür- blattsektionen zu vermeiden.If the push pin is arranged in the door leaf and the associated opening in the frame, then the locking element must also be in the frame and reaches behind the retaining strip, which is then attached to the door leaf. The door leaf or the frames surrounding the door are advantageously equipped with several of the push bolts and locking elements described above. The door leaf can thus be fixed at several points, and in particular in the case of a door leaf composed of several sections, the push bolts and locking elements can be arranged in the lateral lower and / or upper edge regions of the door in order to avoid a relative movement of the individual door leaf sections.
Es wird vorgeschlagen, die axial verschiebbaren Schubbolzen in der Zarge und die damit korrespondierenden Öffnungen im Türblatt anzubringen. In dieser Ausgestaltung ist es möglich, den weiter unten be- schriebenen Antrieb der Schubbolzen ebenfalls an oder im Bereich derIt is proposed to attach the axially displaceable push pins in the frame and the corresponding openings in the door leaf. In this embodiment, it is possible to also drive the push pin described below on or in the area of the
Zargen, d. h. im Tor unterzubringen.Frames, d. H. to accommodate in the gate.
Alternativ dazu können die Schubbolzen auch im Türblatt und die Öffnungen in der Zarge angebracht werden. Die Energieversorgung, bei- spielsweise eine Stromleitung für einen elektrischen Bolzenantrieb, können dabei in geeigneter Weise, z. B. mit flexiblen Kabeln, vom Tor in das Türblatt geführt werden.Alternatively, the push pins can also be installed in the door leaf and the openings in the frame. The energy supply, for example a power line for an electric bolt drive, can be suitably, for. B. with flexible cables from the gate into the door leaf.
Zum Antrieb der Schubbolzen wird vorgeschlagen, dass sie elektro- magnetisch, z. B. über elektrische Stellmotoren oder mit Magnetschaltern, hydraulisch oder pneumatisch mit dem Fachmann bekannten Hydraulik- oder Pneumatiksystem, oder mechanisch bewegbar sind. Eine mechanische Bewegbarkeit des Schubbolzens kann beispielsweise nach Art eines bei konventionellen Türen verwendeten Schnappschlos- ses erfolgen, d. h. der Schubbolzen wird mit Federkraft bewegt und in die Öffnung in Eingriff gebracht. Dazu kann die Spitze des Schubbolzens auch halbkugelförmig abgerundet sein, um ein Ein- und Ausrasten aus der Öffnung zu ermöglichen. Des weiteren ist es dem Fachmann möglich, eine beliebige mechanische Vorrichtung anzubringen, die denTo drive the push pin it is proposed that they be electromagnetic, eg. B. via electric servomotors or with magnetic switches, hydraulically or pneumatically with the hydraulic or pneumatic system known to the person skilled in the art, or can be moved mechanically. A mechanical movement of the push pin can, for example, take the form of a snap lock used in conventional doors. This takes place, ie the push pin is moved with spring force and brought into engagement in the opening. For this purpose, the tip of the push pin can also be rounded off in a hemispherical manner in order to enable it to snap in and out of the opening. Furthermore, it is possible for the person skilled in the art to attach any mechanical device that the
Schubbolzen in Schließstellung arretiert, sobald das Tor angehoben wird.Push pin locked in the closed position as soon as the gate is raised.
Eine weitere vorteilhafte Ausgestaltung der Erfindung besteht darin, dass an der Unterseite des Türblattes weitere Bolzen in der Hauptebene des Tores vertikal angeordnet sind, die eventuell verschiebbar sind, und, im geschlossenen Zustand des Tores, in dazu korrespondierende Öffnung im Boden eingreifen können. Eine möglicherweise aus Sicherheitsbedenken erwünschte oder erforderliche zusätzliche Verschieb- barkeit der Bolzen kann ebenfalls in der oben beschriebenen Weise realisiert werden. In beiden Ausführungen dienen die Bolzen zunächst dazu, das Tor im geschlossenen Zustand zu stabilisieren, d. h. dass eine Bewegung des Tores und der Tür senkrecht zu seiner Hauptebene unterbunden ist. Eine solche Bewegung, beispielsweise unter dem Einfluß starken Winddrucks, würde auf Dauer zu Beschädigungen desAnother advantageous embodiment of the invention is that further bolts are arranged vertically on the underside of the door leaf in the main plane of the door, which may be displaceable, and, when the door is closed, can engage in a corresponding opening in the floor. Any additional displaceability of the bolts which may be desired or required for safety reasons can also be implemented in the manner described above. In both versions, the bolts are initially used to stabilize the door in the closed state, i.e. H. that movement of the gate and door perpendicular to its main plane is prevented. Such a movement, for example under the influence of strong wind pressure, would permanently damage the
Tores führen. Die zusätzliche Verschiebbarkeit der Bolzen über einen Antrieb kann, besonders im Bereich der Tür, als zusätzliche Sicherung gegen unbefugtes Benutzen dienen.Lead tores. The additional displaceability of the bolts via a drive can serve as additional security against unauthorized use, especially in the area of the door.
Vorteilhafterweise beträgt die Länge der Bolzen das drei- bis achtfache des Bolzendurchmessers. Bei geeigneter Materialwahl, insbesondere Metall- oder Edelstahl, können Bolzen mit einer derartigen Abmaßung ein maximales Biegemoment senkrecht ihrer Längsachse aufnehmen, ohne sich unter dessen Einfluß zu verformen. In einer vorteilhaften Ausgestaltung der Erfindung wird durch mindestens zwei der vertikal angeordneten Bolzen, den axial verschiebbaren Schubstößeln, die Bewegung der Schubbolzen angetrieben. Dazu kann der obere Bereich der beiden Schubstößel als Zahnstange ausgebildet sein, die bei ihrer vertikalen Bewegung nach oben, die über Zahnräder und ein Stahlband umgelenkt wird, den Schubbolzen aus der dazugehörenden Öffnung zieht.The length of the bolt is advantageously three to eight times the bolt diameter. With a suitable choice of material, in particular metal or stainless steel, bolts with such a dimension can absorb a maximum bending moment perpendicular to their longitudinal axis without being deformed under its influence. In an advantageous embodiment of the invention, the movement of the thrust bolts is driven by at least two of the vertically arranged bolts, the axially displaceable thrust tappets. For this purpose, the upper area of the two push rods can be designed as a toothed rack, which pulls the push pin out of the associated opening when it moves vertically upwards, which is deflected via toothed wheels and a steel band.
Dabei wird der Schubbolzen vorteilhafterweise gegen eine Druckfeder bewegt, die durch die Bewegung gespannt wird.The push pin is advantageously moved against a compression spring that is tensioned by the movement.
Insgesamt wird beim Schließen des Tores der Schubbolzen zurückbewegt und die Tür freigegeben. Beim Öffnen des Tores springen die Schubbolzen, angetrieben durch die Entspannung der Druckfedern, zurück in die Öffnungen und arretieren die Tür.Overall, when the gate closes, the push pin is moved back and the door is released. When the gate is opened, the push pins, driven by the release of the pressure springs, jump back into the openings and lock the door.
Gleichzeitig zu diesem Vorgang werden die Türsegmente durch die Riegelelemente gesichert, die hinter die Halteleisten einrasten, wie o- ben beschrieben.At the same time as this process, the door segments are secured by the locking elements, which snap into place behind the retaining strips, as described above.
Insgesamt wird durch diese gemeinsam wirkenden Vorrichtungen die Tür beim Öffnen des Tores arretiert und nach dem Schließen für die Benutzung freigegeben.Overall, these jointly acting devices lock the door when the gate is opened and release it for use after it is closed.
Zur Erhöhung der Gebrauchssicherheit des Tores wird vorgeschlagen, dass an der Unterkante des Tores eine an sich bekannte elektrome- chanische Sicherheitsleiste angeordnet ist, bei der ein leistenförmiger Geber in vertikaler Richtung entgegen einer Federkraft bewegbar ist. Sollte sich beim Schließen des Tores ein Gegenstand oder eine Person unterhalb des Tores befinden, wird die Kontaktleiste durch den Widerstand des Objekts relativ zum Tor bewegt und ein elektrischer Kontakt geschlossen, der mit einer Abschaltautomatik für den Torantrieb ver- bunden ist. Vorteilhafterweise ist die Sicherheitsleiste dreiteilig ausgeführt, d. h. dass links und rechts am Tor und an der Tür jeweils an der Unterkante eine Leiste angebracht ist. Dabei kann der Fachmann vorteilhaft die Leisten in geeigneter Weise so elektrisch miteinander verbinden, dass bei Auslösung auch nur einer Leiste die Abschaltautoma- tik reagiert und den Tor-Antrieb abschaltet. Dadurch ist die Sicherheit beim Aufenthalt unter allen drei Tor-Teilen gewährleistet.To increase the safety in use of the door, it is proposed that an electromechanical safety strip, known per se, be arranged on the lower edge of the door, in which a strip-shaped sensor can be moved in the vertical direction against a spring force. If an object or a person is below the gate when the gate is closed, the contact strip is moved relative to the gate by the resistance of the object and an electrical contact is closed, which is connected to an automatic shutdown for the gate operator. Advantageously, the security bar is made in three parts, that is to say that a bar is attached to the left and right of the gate and to the door on the lower edge. Here, the person skilled in the art can advantageously connect the strips to one another in a suitable manner in such a way that when only one strip is triggered, the automatic switch-off reacts and switches off the door drive. This ensures safety when staying under all three gate parts.
Einem weiteren Vorteil stellt eine Vorrichtung dar, mit der der am untersten Türblattsegment angebrachte Teil der Schutzkontaktleiste verti- kal schwenkbar oder anhebbar ist, weil die Tür nur leicht geöffnet werden kann, wenn die Kontaktleiste nicht auf dem Boden aufliegt.A further advantage is a device with which the part of the protective contact strip attached to the lowest door leaf segment can be pivoted or lifted vertically, because the door can only be opened slightly if the contact strip is not lying on the floor.
Um die Kontaktleiste vom Boden abzuheben, kann ein Antrieb eingebaut sein, der beim Öffnen der Tür, z. B. schon beim Betätigen der Türklinke, aktiviert wird.In order to lift the contact strip off the floor, a drive can be installed which, when the door is opened, e.g. B. is already activated when the door handle is actuated.
Um die Tür auch als Fluchtweg verwenden zu können, wird sie mit einem dem Fachmann bekannten Panikschloß ausgestattet. Dieses erlaubt das Öffnen auch einer abgeschlossenen Tür von innen, bei- spielsweise durch einfaches Herunterdrücken der Türklinke. Damit ist die rasche Evakuierung von Personen aus einem Gebäude ermöglicht, auch wenn diese nicht über einen geeigneten Schlüssel für die Tür verfügen. Bei einem vorgesehenen Antrieb der vertikal verlaufenden Bolzen an der Unterkante des Türblattes wird empfohlen, sie in Wirkverbindung mit dem Türgriff oder dem Türschloß zu stellen. Das bedeutet, dass bei Betätigung des Türgriffs oder Türschlosses, beispielsweise um die Tür zu öffnen, die Bolzen synchron verschoben werden. Dabei müssen sie zum Öffnen der Tür nach oben aus den Öffnungen im Boden herausgezogen und beim Schließen eingeschoben werden.In order to be able to use the door as an escape route, it is equipped with a panic lock known to the expert. This also allows a locked door to be opened from the inside, for example by simply pressing the door handle down. This enables people to be evacuated quickly from a building, even if they do not have a suitable key for the door. If the vertical bolts on the lower edge of the door leaf are intended to be driven, it is recommended that they be operatively connected to the door handle or door lock. This means that when the door handle or door lock is actuated, for example to open the door, the bolts are moved synchronously. To open the door, they have to be pulled up out of the openings in the floor and pushed in when closing.
Der Antrieb der Bolzen kann auch hier wie oben beschrieben erfolgen, und es kann z. B. beim Öffnen der Türe ein elektrischer Kontakt geschlossen werden, der einen elektrischen oder magnetischen Bolzenantrieb in Bewegung setzt. Insbesondere wird eine mechanische Wirkverbindung zwischen Bolzen und Türgriff vorgeschlagen, die aus einem Gestänge besteht, wobei dieses in Höhe des Türschlosses mit einer Zahnleiste ausgestattet ist, die in unmittelbaren Eingriff zu einem gezahnten Quadranten steht, der über die Türklinke um eine horizontale Achse verschwenkt wird. Das Gestänge bzw. die mit dem Bolzen verbundene Schubstange muß dabei in Höhe der horizontalen Schwenkachsen, an denen die einzelnen benachbarten Sektionen relativ zuein- ander verschwenkbar sind, ebenfalls über ein koaxiales Gelenk verfügen, um den Knick- bzw. Faltvorgang beim Öffnen des Tores zu ermöglichen.The drive of the bolt can also take place here as described above, and it can, for. B. when opening the door, an electrical contact is closed, which sets an electric or magnetic bolt drive in motion. In particular, a mechanical operative connection between the bolt and the door handle is proposed, which consists of a linkage, which is provided at the level of the door lock with a toothed strip which is in direct engagement with a toothed quadrant which is pivoted about a horizontal axis via the door handle. The linkage or the push rod connected to the bolt must also have a coaxial joint at the level of the horizontal pivot axes, on which the individual neighboring sections can be pivoted relative to one another, in order to prevent the folding or folding process when the door is opened enable.
Zur Verhinderung einer Bewegung des Türblattes in horizontaler Rich- tung in der Hauptebene des Tores wird das Türblatt und/oder die vertikalen Zargen mit hakenartigen Vorrichtungen ausgestattet, die entsprechend geformte Vorsprünge an Zargen bzw. Türblatt im geschlossenen Zustand der Tür hintergreifen. Insbesondere werden diese Haken im Bereich der Bolzen angeordnet, um ein Aufziehen des Spaltes zwischen Türblatt und Zarge, z. B. während des Öffnens zu verhindern.To prevent the door leaf from moving in the horizontal direction in the main plane of the door, the door leaf and / or the vertical frames are equipped with hook-like devices which engage behind correspondingly shaped projections on the frame or door leaf when the door is closed. In particular, these hooks in Area of the bolts arranged to open the gap between the door leaf and frame, for. B. to prevent during opening.
Eine weitere vorteilhafte Ausgestaltung der Erfindung besteht darin, dass auf beiden Schmalseiten des Tores im unteren Bereich eine Andrückrolle angebracht ist, die beim Schließen des Tores auf eine Zentrier- oder Arretierkurve aufläuft, die im unteren Bereich der Torzarge angebracht ist. Dadurch werden das Tor und die Tür im unteren Bereich zusammengeführt, ihre Position festgelegt und die Bolzen über den Öffnungen zentriert.A further advantageous embodiment of the invention consists in that a pressure roller is attached in the lower region on both narrow sides of the door, which, when the door closes, runs onto a centering or locking curve which is attached in the lower region of the door frame. This brings the door and door together in the lower area, determines their position and centers the bolts over the openings.
Damit wird erreicht, dass der Schubbolzen passgenau in die Öffnung eingeführt wird, wobei das Riegelelement so verschwenkt wird, dass es hinter der Halteleiste einrastet und gleichzeitig den elektrisch leitenden Kontakt zwischen den einzelnen Teilen der Sicherheitskontaktleiste herstellt.This ensures that the push pin is inserted precisely into the opening, the locking element being pivoted in such a way that it engages behind the retaining bar and at the same time establishes the electrically conductive contact between the individual parts of the safety contact bar.
Damit der Zweck einer genauen Zentrierung erreicht wird, der die einwandfreie Funktion des Schließmechanismus sicherstellt, ist die Höhe der Zentrier- oder Arretierkurve vorteilhaft variabel einstellbar gestaltet, so dass jederzeit nachjustiert werden kann.The height of the centering or locking curve is advantageously designed to be variably adjustable so that the purpose of precise centering, which ensures the perfect functioning of the locking mechanism, is achieved, so that readjustments can be made at any time.

Bei dem in Figur 1 dargestellten Ausführungsbeispiel der Erfindung handelt es sich um ein Sektionalhubtor, das aus mehreren, im wesentlichen rechteckigen Sektionen (1) besteht, die an horizontal verlaufenden Schwenkachsen (2) parallel ihrer Längsseiten relativ zueinander verschwenkbar sind. Um das Passieren des Tores für Personen zu er- möglichen, ohne dass das Tor an sich geöffnet werden muß, ist eineThe exemplary embodiment of the invention shown in FIG. 1 is a sectional lifting gate which consists of a plurality of essentially rectangular sections (1) which can be pivoted relative to one another parallel to their longitudinal sides on horizontally running pivot axes (2). To enable people to pass through the gate without having to open the gate itself, there is one
Tür eingesetzt, deren Türblatt seinerseits aus einzelnen Türblattsektionen (4) zusammengesetzt ist, wobei die horizontalen Schwenkachsen (5) zwischen benachbarten Türsektionen (4) koaxial zu den oben genannten Schwenkachsen (2) des Tores angeordnet sind. An der Unter- kante des Tores und der Tür ist eine dreigeteilte elektrische Schutzkontaktleiste (3) angebracht, die an eine Abschaltautomatik für den Torantrieb gekoppelt ist. In Figur 2 ist das Hubtor in halb aufgezogenem Zustand dargestellt. Hierbei erfolgt in dem Winkel zwischen Wand und Decke eine Ver- schwenkung der einzelnen Sektionen (1) im wesentlichen um 90° derart, dass in vollständig geöffnetem Zustand das Tor parallel zur Decke verläuft.Door is used, the door leaf of which in turn is composed of individual door leaf sections (4), the horizontal pivot axes (5) being arranged between adjacent door sections (4) coaxially with the above-mentioned pivot axes (2) of the door. A three-part electrical protective contact strip (3) is attached to the bottom edge of the door and door, which is coupled to an automatic switch-off for the door operator. In Figure 2, the lifting gate is shown in the half-open state. In the angle between the wall and the ceiling, the individual sections (1) are pivoted essentially by 90 ° in such a way that the gate runs parallel to the ceiling when fully open.
In Figur 3 sind die beiden untersten, bodenseitigen Sektionen (4) einer erfindungsgemäßen Tür eines Hubtores im geschlossenen Zustand dargestellt. Die unterste Sektion (4) liegt im wesentlichen formschlüssig mit ihrer Unterkante auf dem Boden (6) auf, zur Abdichtung kann auch eine zusätzliche Gummilippe an ihr angebracht sein. Ein in der Hauptebene des Tores angeordneter, möglicherweise in vertikaler Richtung axial verschiebbarer Bolzen (7) greift hier in eine mit ihm korrespondierende Öffnung (8) im Boden (6) unterhalb des Tores ein, wie es durch den Pfeil angedeutet ist. Damit wird eine Bewegung des Tores bzw. derIn Figure 3, the two bottom, bottom sections (4) of a door of a lifting gate according to the invention are shown in the closed state. The bottom section (4) lies essentially in a form-fitting manner with its lower edge on the floor (6); an additional rubber lip can also be attached to it for sealing. A bolt (7), which is arranged in the main plane of the door and is possibly axially displaceable in the vertical direction, engages in an opening (8) in the floor (6) below the door corresponding to it, as indicated by the arrow. This is a movement of the gate or
Tür senkrecht zur Ebene des Tores, beispielsweise unter dem Einfluß des Winddrucks, verhindert. Zwischen den beiden Sektionen (4) ist eine vom Fachmann beliebig ausführbare Schwenkachse (5) angeordnet, an der die beiden Sektionen (4) relativ zueinander verschwenkt werden können. Desweiteren ist ein Schubbolzen (9) dargestellt, der in Eingriff in eine Zarge (10) gebracht werden kann, wobei er axial, senkrecht zur Bildebene verschiebbar ist. Zur Vereinfachung der Darstellung wurde auf die Abbildung einer Antriebsvorrichtung für die Bolzen (7, 9) verzichtet. Sie kann auf vielfältige Weise elektromagnetisch, hydraulisch, pneumatisch oder mechanisch ausgelegt und auch mit einer geeigneten Steuerelektronik verbunden sein.Door perpendicular to the plane of the gate, for example under the influence of wind pressure, prevented. Between the two sections (4) is arranged a pivot axis (5) which can be designed by a person skilled in the art and on which the two sections (4) can be pivoted relative to one another. Furthermore, a push pin (9) is shown, which can be brought into engagement in a frame (10), wherein it can be moved axially, perpendicular to the image plane. To simplify the illustration, the illustration of a drive device for the bolts (7, 9) has been omitted. It can be designed electromagnetically, hydraulically, pneumatically or mechanically in a variety of ways and can also be connected to suitable control electronics.
In Figur 4 ist die Sektion (1) eines Tores mit einer Sektion (4) des Türblattes im vertikalen Querschnitt dargestellt. Im Türblatt ist links und rechts seitlich je ein Schubbolzen (9) angeordnet, der axial, in horizontaler Richtung in der Hauptebene des Tores verschiebbar ist, wie es durch die Pfeile angedeutet wird. Dabei kann er in Eingriff in eine korrespondierende Öffnung (11) in der Zarge (10) gebracht werden, die an der Türöffnung an drei Seiten umlaufend angeordnet ist. Zur Betätigung der Schubbolzen (9) wird ein beliebig wählbarer Antrieb (12) verwendet.In Figure 4, the section (1) of a gate with a section (4) of the door leaf is shown in vertical cross section. In the door leaf is left and On the right side a push pin (9) is arranged, which is axially, horizontally displaceable in the main plane of the door, as indicated by the arrows. It can be brought into engagement in a corresponding opening (11) in the frame (10), which is arranged around the door opening on three sides. An arbitrarily selectable drive (12) is used to actuate the push pins (9).
In Figur 5 ist ein vertikaler Schnitt durch das Tor in Höhe der Laufrollen dargestellt. Im unteren Bereich des Tores sind die beiden als Zahnstange ausgebildeten Schubstößel (13) zu erkennen, deren Bewegung über die Zahnräder (14) (Ritzel) und das Stahlband (15) zu den Schubbolzen (9) umgelenkt wird. Beim Schließen des Tores wird das Stahlband (15) aufgerollt. Es zieht dabei die Schubbolzen (9) aus den Öffnungen (11) und spannt die Druckfeder (16), deren Federkraft bei der Entspannung der Feder die Schubbolzen (9) beim Öffnen des Tores wieder in die Öffnungen (11) schiebt.In Figure 5, a vertical section through the gate is shown at the level of the rollers. In the lower area of the gate, the two pushrods (13) designed as toothed racks can be seen, the movement of which is deflected via the gears (14) (pinion) and the steel band (15) to the pusher pins (9). When the gate closes, the steel band (15) is rolled up. It pulls the push pins (9) out of the openings (11) and tensions the compression spring (16), the spring force of which pushes the push pins (9) back into the openings (11) when the gate is opened when the spring is released.
An der Schmalseite des Tores sind die Andrückrollen (17) angebracht, die beim Schließen des Tores auf die Zentrier- oder Arretierkurve (18) aufgelaufen sind und das Tor zentriert haben. Beim Öffnen des Tores laufen sie im oberen Bereich der Torzarge auf Laufschienen (19) oder frei.The pressure rollers (17) are attached to the narrow side of the door. When the door closes, they are pressed onto the centering or locking cam (18) and centered the door. When the door is opened, they run in the upper area of the door frame on running rails (19) or freely.
Figur 6 zeigt einen horizontalen Schnitt durch das Tor bei teilweise ge- öffneter Tür. Deutlich sind die an der Türzarge angeordneten Halteleisten (20) bzw. Widerlager zu erkennen, hinter die die an der Tür angebrachten Riegelelemente (21) (z. B. Sperrklinken) fassen, um die Tür in der Zarge (10) zu fixieren. Figur 7 zeigt einen Ausschnitt von Figur 6, in dem die Anordnung von Laufrollen (22) und Andrückrolle (17) zueinander verdeutlicht ist.Figure 6 shows a horizontal section through the gate with the door partially open. The retaining strips (20) or abutments arranged on the door frame can be clearly seen, behind which the locking elements (21) (e.g. pawls) attached to the door grip to fix the door in the frame (10). Figure 7 shows a section of Figure 6, in which the arrangement of rollers (22) and pressure roller (17) to one another is illustrated.
In Figur 8 ist ein Schnitt durch die Tür und die Türzarge in Höhe der Schubbolzen (9) dargestellt. Es sind die Halteleiste (20) und das Riegelelement (21) erkennbar, das in den Bewegungsquerschnitt des Schubbolzens (9) hineinragt und beim Verschieben des Schubbolzens (9) von diesem so verschwenkt wird, dass das rastenartig ausgebildete Ende hinter der Kante der Halteleiste (20) am einzelnen Tor- oder Tür- segment einrastet.FIG. 8 shows a section through the door and the door frame at the level of the push pins (9). The retaining strip (20) and the locking element (21) can be seen, which protrudes into the movement cross section of the push bolt (9) and is pivoted by the push bolt (9) when it is displaced such that the detent-like end behind the edge of the retaining strip ( 20) clicks into place on the individual gate or door segment.
Figur 9 zeigt einen Querschnitt durch den unteren Bereich der Tür.
