Description

K I P P T O R K I P P T O R
Die Erfindung betrifft ein Kipptor mit einem Torblatt, welches entlang im wesentlichen horizontal verlaufender, innerhalb eines Gebäudes angeordneter Führungsschienen zwischen einer Öffnungsstellung und einer Schließstellung verschiebbar ist, wobei das Kipptor unterhalb der Führungsschienen über als zweiseitige Hebel wirkende Lenker an einer Zarge angelenkt ist, welche Lenker um eine Drehachse verdrehbar an der Zarge befestigt, mit einem ersten Ende verdrehbar an dem Torblatt angeordnet und mit einem zweiten Ende über Federn zum Gewichtsausgleich gegenüber dem Gebäude abgestützt sind.The invention relates to a tilting gate with a door leaf which can be displaced between an open position and a closed position along essentially horizontally running guide rails arranged inside a building, the tilting gate being articulated below a guide frame on the handlebars acting as two-sided levers, which links attached to the frame so as to be rotatable about an axis of rotation, arranged with a first end so as to be rotatable on the door leaf and supported with a second end via springs for weight compensation in relation to the building.
Derartige Kipptore sind bekannt. Beispielsweise werden derartige Kipptore als Garagentore verwendet, die entweder für Garagen mit einem Stellplatz oder mit zwei nebeneinander liegenden Stellplätzen geeignet sind. Dementsprechend sind die Kipptore unterschiedlich dimensioniert, wobei auch Kipptore für andere Ein¬ satzzwecke bekannt sind, deren Abmessungen und das damit verbundene Ge¬ wicht wesentlich über den Abmessungen und dem Gewicht eines Garagentores für eine Garage mit zwei Stellplätzen liegt. Die gattungsgemäßen Kipptore wei¬ sen in der Regel an ihren seitlichen oberen Enden Laufrollen auf, die in im wesentlichen horizontal verlaufenden Führungsschienen geführt sind, welche bei¬ spielsweise an der Decke eines Gebäudes angehängt sind. Darüberhinaus sind beidseitig des Torblattes Lenker gelenkig an dem Kipptor befestigt, welche um eine Drehachse drehbar an einer Zarge gelagert sind, die in der Mauerwerksöff¬ nung beispielsweise einer Garage an der Mauerleibung befestigt ist. An dem dem Befestigungspunkt der Lenker am Torblatt gegenüberliegenden Ende der Lenker sind Federn angeordnet, die einerseits in entsprechende Bohrungen des Lenkers eingehängt und andererseits im Bodenbereich des Gebäudes, vorzugsweise an der Zarge angeschlagen sind. Diese Federn sind in Abhängigkeit des Gewichtes des Kipptores dimensioniert und können beispielsweise auch als Doppelfedern, d.h. als zwei nebeneinander angeordnete Federn ausgebildet sein. Die Federn dienen dem Gewichtsausgleich beim Bewegen des Torblattes aus seiner Öffnungsstellung in seine Schließstellung und umgekehrt. Hierbei wird durch die Federn eine der Gewichtskraft beim Schließen des Torblattes entgegenwirkende Kraft dadurch er¬ zeugt, daß die Federn beim Schließen des Torblattes gespannt werden. In umge¬ kehrter Weise unterstützten die in der Schließstellung vorgespannten Federn das Überführen des Torblattes aus der Schließstellung in die Öffnungsstellung, da die durch die Vorspannung in den Federn gespeicherte Energie beim Öffnen des Torblattes über die Lenker auf das sich bewegende Torblatt übertragen wird.Such tilting gates are known. For example, tilting doors of this type are used as garage doors, which are suitable either for garages with one parking space or with two parking spaces lying next to one another. Accordingly, the tilting gates are dimensioned differently, whereby tilting gates are also known for other purposes, the dimensions and the associated weight of which are substantially greater than the dimensions and weight of a garage door for a garage with two parking spaces. The tilting gates of the generic type generally have rollers on their lateral upper ends which are guided in essentially horizontally running guide rails which are attached, for example, to the ceiling of a building. In addition, on both sides of the door leaf, links are articulated to the tilt gate, which are rotatably mounted about an axis of rotation on a frame which is fastened in the masonry opening, for example a garage, to the wall reveal. On that Fastening point of the handlebars on the door leaf opposite end of the handlebars are springs which are hooked into corresponding holes in the handlebars on the one hand and on the other hand are preferably attached to the frame in the floor area of the building. These springs are dimensioned as a function of the weight of the tilting door and can also be designed, for example, as double springs, ie as two springs arranged next to one another. The springs serve to balance the weight when moving the door leaf from its open position to its closed position and vice versa. In this case, a force which counteracts the weight when the door leaf closes is generated by the springs in that the springs are tensioned when the door leaf closes. Conversely, the springs pretensioned in the closed position support the transfer of the door leaf from the closed position to the open position, since the energy stored in the springs by the pretension is transmitted via the handlebars to the moving door leaf when the door leaf is opened.
Bei derartigen Kipptoren ist die Montage sehr kraft- und arbeitsintensiv, da ins¬ besondere bei größeren Kipptoren, d.h. bei solchen mit einem hohen Gewicht sehr starke Schraubenfedern zum Gewichtsausgleich verwendet werden müssen, die beim Einbau des Kipptores vorgespannt werden. Diese Arbeitsweise ist dar- überhinaus sehr unfallträchtig, da durch das Vorspannen der Federn große Ener¬ gien aufgebracht werden müssen, die bei nicht ordnungsgemäßer Montage der Federn zu einem Abrutschen der Federn führen können.With tilting gates of this type, the assembly is very energy-intensive and labor-intensive, since in particular with larger tilting gates, i.e. for those with a high weight, very strong coil springs must be used to balance the weight, which are preloaded when the tilting gate is installed. This method of operation is also very accident-prone since large energies have to be applied by pretensioning the springs, which can cause the springs to slip if the springs are not properly installed.
Ausgehend von diesem Stand der Technik liegt der Erfindung die A u f g a b e zugrunde, ein Kipptor der gattungsgemäßen Art zu schaffen, das auch bei sehr großen Abmessungen und den damit verbundenen starken Federn in einfacher und sicherer Weise montierbar ist.Starting from this prior art, the invention is based on the objective of creating a tilting gate of the generic type which can be installed in a simple and safe manner even with very large dimensions and the strong springs associated therewith.
Die L ö s u n g dieser Aufgabenstellung sieht bei einem gattungsgemäßen Kipp¬ tor vor, daß im Bereich der Drehachse der Lenker eine Vorrichtung zum Vor¬ spannen der Federn angeordnet ist, die bei der Montage des Tores mit den Fe¬ dern verbunden und mit dem zweiten Ende des Lenkers, vorzugsweise in Öff¬ nungsstellung des Tores verbindbar ist. Bei dem erfindungsgemäßen Kipptor ist somit eine Einrichtung zum Vorspannen der Federn vorgesehen, wobei die Vorspannung der Federn nur in einem be¬ stimmten kleinen Maß ausgeführt wird. Die Vorrichtung ist hierzu bei der Mon¬ tage des Tores mit den Federn verbunden. Nachdem die Federn im Bereich des Torblattes montiert sind, wird das Torblatt beispielsweise aus seiner Schlie߬ stellung in seine Öffnungsstellung überführt, wodurch die zweiten Enden der Lenker in den Bereich der Vorrichtung zum Vorspannen der Federn gelangen. In der Öffnungsstellung des Tores kann dann die Vorrichtung zum Vorspannen der Federn mit dem zweiten Ende des Lenkers verbunden werden, so daß beim Schließen des Torblattes die Vorrichtung zum Vorspannen der Federn mit den Lenkern um die Drehachse verschwenkt wird, wodurch eine weitere Vorspan¬ nung, nämlich die für die Handhabung eines derartigen Tores notwendige Vor¬ spannung in den Federn erzeugt wird. Hierdurch wird eine konstruktiv einfache Ausgestaltung des erfindungsgemäßen Kipptores, insbesondere der erfindungs¬ gemäßen Vorrichtung erzielt, wobei der Schwingarm beispielsweise an der Zarge oder auch am Mauerwerk des Gebäudes befestigt werden kann.The solution to this task provides in a generic tilting gate that a device for biasing the springs is arranged in the region of the axis of rotation of the link, which is connected to the springs and to the second end when the gate is assembled of the handlebar, preferably in the open position of the gate. In the tilting gate according to the invention, a device for prestressing the springs is thus provided, the prestressing of the springs being carried out only to a certain small extent. For this purpose, the device is connected to the springs during the assembly of the gate. After the springs have been mounted in the area of the door leaf, the door leaf is, for example, transferred from its closed position into its open position, as a result of which the second ends of the links reach the area of the device for pretensioning the springs. In the open position of the gate, the device for pretensioning the springs can then be connected to the second end of the handlebar, so that when the door leaf is closed, the device for pretensioning the springs with the handlebars is pivoted about the axis of rotation, as a result of which a further pretensioning, namely the pretension necessary for handling such a gate is generated in the springs. In this way, a structurally simple configuration of the tilting gate according to the invention, in particular the device according to the invention, is achieved, the swing arm being able to be fastened, for example, to the frame or to the masonry of the building.
Nach einem weiteren Merkmal der Erfindung ist vorgesehen, daß der Schwingarm im Querschnitt im wesentlichen U-förmig ausgebildet ist und vorzugsweise an einem Lagerbock schwenkbeweglich angeordnet ist, der an der Zarge oder un¬ mittelbar am Mauerwerk des Gebäudes befestigbar ist. Bei dieser Ausgestaltung ist es insbesondere möglich, die Kombination aus Schwingarm und Lagerbock auch bei solchen Toren einzusetzen, die eine entsprechende Vorrichtung zum Vorspannen der Federn nicht aufweist. Es handelt sich demzufolge um eine selb¬ ständig handhabbare Vorrichtung, die auch bei bereits bestehenden Toren nach¬ gerüstet werden kann, beispielsweise im Zuge von Wartungsarbeiten, bei denen Federn ausgetauscht werden. Hierbei wird der Lagerbock mit der Zarge ver¬ schraubt. An dem Lagerbock ist der Schwingarm, der im Querschnitt im wesentlichen U-förmig ausgebildet ist, mit zumindest einem Schenkel, vorzugsweise mit beiden Schenkeln drehbar befestigt.According to a further feature of the invention, it is provided that the swing arm is essentially U-shaped in cross-section and is preferably arranged so as to be pivotable on a bearing block which can be fastened to the frame or directly to the masonry of the building. With this configuration, it is in particular possible to use the combination of the swing arm and bearing block even in the case of gates which do not have a corresponding device for prestressing the springs. It is therefore a device which can be handled independently and which can also be retrofitted to existing gates, for example in the course of maintenance work in which springs are replaced. The bearing block is screwed to the frame. The swing arm, which is essentially U-shaped in cross section, is rotatably attached to the bearing block with at least one leg, preferably with both legs.
Eine einfache Befestigung der Federn an der Vorrichtung zum Vorspannen der Fedem wird dadurch erzielt, daß die Vorrichtung an ihrem dem Drehpunkt ge¬ genüberliegenden Ende eine Achse aufweist, an welcher ein hakenförmiges Ele¬ ment zur Verbindung der Vorrichtung mit der Feder bzw. den Fedem eingehängt ist. Es ist hierbei nach einem weiteren Merkmal vorgesehen, daß das haken¬ förmige Element an seinem der Achse gegenüberliegenden Ende abgewinkelt ist und eine Bohrung aufweist, die vorzugsweise von einem Gewindestab durch¬ griffen ist, an welchem die Feder bzw. die Fedem befestigt sind. Durch den Gewindestab kann die Vorspannung der Fedem nach der Montage des haken¬ förmigen Elementes an der Vorrichtung zum Vorspannen der Fedem eingestellt werden.A simple attachment of the springs to the device for biasing the Fedem is achieved in that the device has at its end opposite the pivot point an axis on which a hook-shaped element for connecting the device to the spring or springs is suspended. It is provided according to a further feature that the hook-shaped element is angled at its end opposite the axis and has a bore which is preferably passed through by a threaded rod to which the spring or springs are attached. The prestressing of the springs can be adjusted by the threaded rod after the hook-shaped element has been mounted on the device for prestressing the springs.
Eine einfache Befestigung des zweiten Endes des Lenkers an der Vorrichtung zum Vorspannen der Fede wird dadurch erzielt, daß die Achse an zumindest einem Ende ein Innengewinde hat, welches mit einem Bolzen zusammenwirkt, mit wel¬ chem das zweite Ende des Lenkers an der Vorrichtung befestigbar ist. Demzu¬ folge wird bei der Montage des Kipptores das Torblatt in seine Öffnungsstellung überführt, wodurch der Lenker parallel zu dem im wesentlichen vertikal ange¬ ordneten Schwingarm ausgerichtet wird. Mittels eines Bolzens, der durch das zweite Ende des Lenkers gesteckt und in das Innengewinde der Achse geschraubt wird, wird der Schwingarm formschlüssig mit dem zweiten Ende des Lenkers verbunden, so daß beim Schließen des Torblattes der sich um die Drehachse be¬ wegende Lenker den Schwingarm, welcher sich ebenfalls um die Drehachse dreht, mitnimmt, so daß die Federn nunmehr mit der notwendigen Federkraft vorgespannt werden, welche die bestimmungsgemäße Unterstützung der Öff- nungs- und Schließbewegung des Torblattes ermöglicht.A simple attachment of the second end of the handlebar to the device for pretensioning the spring is achieved in that the axle has an internal thread on at least one end, which interacts with a bolt with which the second end of the handlebar can be attached to the device . Accordingly, the door leaf is moved into its open position during assembly of the tilting door, as a result of which the handlebar is aligned parallel to the essentially vertically arranged swing arm. By means of a bolt which is inserted through the second end of the handlebar and screwed into the internal thread of the axle, the swing arm is positively connected to the second end of the handlebar, so that when the door leaf is closed the handlebar moving about the axis of rotation engages the swing arm , which also rotates about the axis of rotation, so that the springs are now pretensioned with the necessary spring force, which enables the intended support of the opening and closing movement of the door leaf.
Das zweite Ende des Lenkers weist hierbei vorzugsweise eine Bohrung auf, die in gleichem radialen Abstand zum Drehpunkt angeordnet ist, wie die Achse der Vorrichtung. In weiterhin bevorzugter Ausführungsform der Erfindung ist vorge¬ sehen, daß jede Feder von einem teleskopierbaren Stab durchgriffen ist, der mit seinen beiden Enden mit den Enden der Feder verbunden, einerseits im Boden¬ bereich verankert und andererseits an dem Hakenelement und/oder dem Gewinde¬ stab befestigt ist. Dieser teleskopierbare Stab besteht im wesentlichen aus zwei Elementen, wobei das eine Element in das zweite Element einschiebbar ist. Vor¬ zugsweise hat der teleskopierbare Stab einen rechteckigen, insbesondere quadra¬ tischen Querschnitt, so daß in einfacher Weise Verschraubungselemente an dem Stab befestigt werden können. Die Länge der beiden ineinander zu schiebenden Elemente ist hierbei abhängig von dem Weg, welcher in horizontaler Richtung zwischen den Endstellungen des Lenkers, d.h. in der Öffnungsstellung des Tor¬ blattes einerseits und der Schließstellung des Torblattes andererseits besteht.The second end of the handlebar preferably has a bore which is arranged at the same radial distance from the fulcrum as the axis of the device. In a further preferred embodiment of the invention, it is provided that each spring is penetrated by a telescopic rod, which is connected with its two ends to the ends of the spring, anchored on the one hand in the bottom area and on the other hand on the hook element and / or the thread rod is attached. This telescopic rod essentially consists of two Elements, wherein the one element can be inserted into the second element. The telescopic rod preferably has a rectangular, in particular square, cross section, so that screwing elements can be attached to the rod in a simple manner. The length of the two elements to be pushed into one another is dependent on the path which exists in the horizontal direction between the end positions of the handlebar, ie in the open position of the door leaf on the one hand and the closed position of the door leaf on the other.
Nach einem weiteren Merkmal der Erfindung ist vorgesehen, daß der Lagerbock im wesentlichen U-förmig ausgebildet ist, wobei die beiden Schenkel des Lager¬ bocks koaxial angeordnete Bohrungen aufweisen, welche die Drehachse definie¬ ren und vorzugsweise mit den Schenkeln des U-förmigen Schwingarms verbun¬ den sind. Diese Ausgestaltung hat insbesondere den Vorteil, daß sie eine stabile Verbindung zwischen Lagerbock und Schwingarm darstellt, so daß auch größere Kräfte, beispielsweise die Kräfte von zwei starken, parallel geschalteten Schrau¬ benfedern auf den Lagerbock übertragen werden können. Vorzugsweise erfolgt die Verbindung zwischen Lagerbock und Schwingarm durch zwei getrennte Bol¬ zen, was insbesondere hinsichtlich der Montagevereinfachung Vorteile hat.According to a further feature of the invention it is provided that the bearing block is essentially U-shaped, the two legs of the bearing block having coaxially arranged bores which define the axis of rotation and are preferably connected to the legs of the U-shaped swing arm ¬ are. This embodiment has the particular advantage that it represents a stable connection between the bearing block and the swing arm, so that larger forces, for example the forces of two strong, parallel helical springs, can be transmitted to the bearing block. The connection between the bearing block and the swing arm is preferably made by two separate bolts, which has advantages in particular with regard to simplifying assembly.
Schließlich ist nach einem weiteren Merkmal der Erfindung vorgesehen, daß ein Schenkel des Schwingarms zwischen dem Lagerbock und dem Lenker angeord¬ net ist.Finally, according to a further feature of the invention, it is provided that one leg of the swing arm is arranged between the bearing block and the handlebar.

Ein in den Figuren 1 bis 3 dargestelltes Kipptor 1 besteht aus einem einen Rah¬ men 2 aufweisenden Torblatt 3, das zwischen einer Öffnungsstellung (Figur 2) und einer Schließstellung (Figur 3) hin- und herbewegbar ist. Hierzu sind an dem Rahmen 2 am oberen Ende Laufrollen 4 in Lagerböcken angeordnet, welche in im wesentlichen horizontal ausgerichteten Führungsschienen 5 geführt sind. Die Führungsschienen 5 sind mit ihrem einen Ende an einer Zarge 6 befestigt und stützen sich darüberhinaus mittels nicht dargestellter Befestigungselemente an einem nicht näher dargestellten Gebäude ab. Beispielsweise sind die Führungs¬ schienen 5 im Deckenbereich einer Garage befestigt.A tilting gate 1 shown in FIGS. 1 to 3 consists of a door leaf 3 having a frame 2, which can be moved back and forth between an open position (FIG. 2) and a closed position (FIG. 3). For this purpose, rollers 4 are arranged in bearing blocks on the frame 2 at the upper end, which are guided in essentially horizontally aligned guide rails 5. The guide rails 5 are fastened at one end to a frame 6 and are additionally supported on a building, not shown, by means of fastening elements (not shown). For example, the guide rails 5 are fastened in the ceiling area of a garage.
Die Zarge 6 setzt sich aus zwei parallel und im wesentlichen lotrecht verlaufen¬ den Elementen sowie einem im wesentlichen horizontal verlaufenden , die beiden lotrechten Elemente verbindenden Element zusammen, wobei die Elemente als Profillei sten, vorzugsweise aus Stahl ausgebildet sind. Bodenseitig ist die Zarge 6 über ein Winkelelement 7 an einem im Bodenbereich angeordneten Schwellen¬ element 8 an •gee*-schlossen.The frame 6 is composed of two parallel and essentially perpendicular elements and an essentially horizontal element connecting the two vertical elements, the elements being designed as profiled strips, preferably made of steel. On the base side, the frame 6 is connected via an angle element 7 to a threshold element 8 arranged in the base area.
An dem Rahmen 2 sind fe er zwei Lenker 9 um jeweils einen Drehpunkt 10 schwenkbeweglich angeschlossen, wobei die Lenker 9 im unteren Bereich des Rahmens 2, d.h. in dem Bereich angeordnet sind, der dem die Laufrollen 4 auf¬ weisenden Bereich des Rahmens 2 gegenüberliegt. Die Lenker 9 sind als Profil- stäbe, vorzugsweise mit rechteckigem Querschnitt ausgebildet und über einen Lagerbock 11 an den vertikal verlaufenden Elementen der Zarge 6 befestigt, wo¬ bei der Lagerbock 11 eine Drehachse 12 hat, um die der Lenker 9 verdrehbar ist. Der Lagerbock 11 ist mittels Schrauben 13 mit der Zarge 6 verschraubt.On the frame 2 he two links 9 are pivotally connected about a pivot point 10, the links 9 being arranged in the lower area of the frame 2, ie in the area opposite the area of the frame 2 which has the rollers 4. The links 9 are designed as profile bars, preferably with a rectangular cross section, and over one Bearing bracket 11 fastened to the vertically extending elements of the frame 6, the bracket 11 having an axis of rotation 12 about which the handlebar 9 can be rotated. The bearing block 11 is screwed to the frame 6 by means of screws 13.
Jeder Lenker 9 hat ein erstes Ende 14, welches am Rahmen 2 befestigt ist und ein zweites Ende 15, welches gegenüber dem Gebäude über zumindest eine Feder 16 zum Gewichtsausgleich abgestützt ist. Die Fede 16 werden bei derartigen Kipptoren 1 beim Bewegen des Torblattes 3 in die Schließstellung gespannt, so daß die Federn 16 beim Schließen des Torblattes 3 eine der Gewichtskraft des Torblattes 3 entgegenwirkende Kraft erzeugen. Im umgekehrten Fall, beim Öff¬ nen des Torblattes 3 werden die Federn 16 entspannt, so daß die sich entspan¬ nenden Fedem 16 die Öffnungsbewegung des Torblattes über das zweite Ende 15 des Lenkers 9 unterstützen. Hierzu sind die Fedem 16 im Bereich des Winkel¬ elementes 7 mittelbar an der Zarge 6 befestigt.Each handlebar 9 has a first end 14 which is attached to the frame 2 and a second end 15 which is supported relative to the building by at least one spring 16 for weight compensation. In such tilting gates 1, the springs 16 are tensioned when the door leaf 3 is moved into the closed position, so that the springs 16 generate a force counteracting the weight of the door leaf 3 when the door leaf 3 is closed. In the opposite case, when the door leaf 3 is opened, the springs 16 are relaxed, so that the relaxing springs 16 support the opening movement of the door leaf via the second end 15 of the link 9. For this purpose, the springs 16 are indirectly attached to the frame 6 in the area of the angle element 7.
Um die Montage eines Kipptores 1 innerhalb des Gebäudes in einfacher und sicherer Weise durchzuführen, ist an dem Lagerbock 11 eine Vorrichtung 17 zum Vorspannen der Fede 16 angeordnet, die bei der Montage des Kipptores 1 mit den Federn 16 verbunden und mit dem zweiten Ende 15 des Lenkers 9 in der Öffnungsstellung des Tores 1 verbindbar ist. Die Vorrichtung 17 zum Vorspan¬ nen der Federn 16 besteht aus einem Schwingarm 18, der um die Drehachse 12 der Lenker verdrehbar an dem Lagerbock 11 angeordnet ist. Der Schwingarm 18 ist im Querschnitt U-förmig ausgebildet, wobei seine beiden Schenkel 19 und 20 über Lagerbolzen 21 und 22 an zwei Schenkeln 23 und 24 des ebenfalls U-förmig ausgebildeten Lagerbocks 1 1 angeordnet, und die beiden Schenkel 23 und 24 über einen Steg 25 miteinander verbunden sind, der mit den Schrauben 13 an der Zarge 6 verschraubt ist. Die beiden Lagerbolzen 21 und 22 sind in koaxial gegen¬ überliegenden Bohrungen der Schenkel 23 und 24 des Lagerbocks 11 angeordnet und bilden die Drehachse 12. Wie insbesondere aus der Figur 4 zu erkennen ist liegt der Schenkel 19 des Schwenkarms 18 an der Innenseite des Schenkels 23 des Lagerbocks 11 und der Schenkel 20 des Schwenkarms 18 an der Aussenseite des Schenkels 24 des Lagerbocks 1 1 an. Parallel zu dem Schenkel 20 ist der Lenker 9, nämlich das zweite Ende 15 angeordnet, wobei der Lenker 9 ebenfalls an dem Lagerbolzen 2 gehalten ist, so daß sich Lenker 9 und Schwingarm 18 um dieselbe Drehachse 12 drehen.In order to carry out the assembly of a tilting gate 1 within the building in a simple and safe manner, a device 17 for biasing the spring 16 is arranged on the bearing block 11, which is connected to the springs 16 during assembly of the tilting gate 1 and to the second end 15 of the Handlebar 9 is connectable in the open position of the gate 1. The device 17 for preloading the springs 16 consists of a swing arm 18 which is arranged on the bearing block 11 so as to be rotatable about the axis of rotation 12 of the links. The swing arm 18 is U-shaped in cross-section, its two legs 19 and 20 being arranged via bearing pins 21 and 22 on two legs 23 and 24 of the likewise U-shaped bearing block 11, and the two legs 23 and 24 via a web 25 are connected to each other, which is screwed to the frame 6 with the screws 13. The two bearing bolts 21 and 22 are arranged in coaxially opposite bores of the legs 23 and 24 of the bearing block 11 and form the axis of rotation 12. As can be seen in particular from FIG. 4, the leg 19 of the swivel arm 18 lies on the inside of the leg 23 of the bearing block 11 and the leg 20 of the swivel arm 18 on the outside of the leg 24 of the bearing block 11. The handlebar 9, namely the second end 15, is arranged parallel to the leg 20, the handlebar 9 likewise is held on the bearing pin 2 so that the link 9 and the swing arm 18 rotate about the same axis of rotation 12.
Der Schwingarm 18 weist an seinem freien Ende in beiden Schenkel 19 und 20 jeweils eine Bohrung auf, die koaxial zueinander angeordnet sind und durch wel¬ che eine Achse 26 gesteckt ist. Diese Achse weist in ihren den Schenkeln 20 zu¬ gewandten Ende eine Bohrung 27 mit Innengewinde auf. Über einen Bolzen 28 ist der Lenker 9 mit seinem zweiten Ende 15 in der montierten Stellung des Kipptores 1 an dem Schwingarm 18 befestigt, wobei der Bolzen 28 in die Boh¬ rung 27 eingeschraubt ist.The swing arm 18 has at its free end in both legs 19 and 20 a bore, which are arranged coaxially to each other and through which an axis 26 is inserted. This axis has in its end facing the legs 20 a bore 27 with an internal thread. The handlebar 9 is fastened to the swing arm 18 with its second end 15 in the assembled position of the tilting gate 1 via a bolt 28, the bolt 28 being screwed into the bore 27.
Wie aus der Figur 4 zu erkennen ist, ist der Lenker 9 als Rohr mit quadratischem Querschnitt ausgebildet, wobei an den Enden des Lenkers 9 Verschlußstopfen 29 angeordnet sind.As can be seen from FIG. 4, the handlebar 9 is designed as a tube with a square cross section, with sealing plugs 29 being arranged at the ends of the handlebars 9.
Auf die Achse 26 ist ein hakenförmiges Element 30 gehängt, welches an seinen der Achse 26 gegenüberliegenden Ende im wesentlichen rechtwinklig abgewin¬ kelt ist und somit einen Steg 31 hat, in dessen Mittelbereich eine Bohrung ange¬ ordnet ist, die von einem Gewindestab 32 durchgriffen ist. Der Gewindestab 32 ist über eine Mutter 33 relativ zum Steg 31 einstellbar, wobei an dem der Mutter 33 gegenüberliegenden Ende des Gewindestabes 32 die Feder 16 befestigt ist, so daß über den Gewindestab 32 die Vorspannung der Feder 16 einstellbar ist.A hook-shaped element 30 is hung on the axis 26, which is angled substantially at right angles at its end opposite the axis 26 and thus has a web 31, in the central region of which a bore is arranged which is penetrated by a threaded rod 32 . The threaded rod 32 is adjustable relative to the web 31 via a nut 33, the spring 16 being fastened to the end of the threaded rod 32 opposite the nut 33, so that the prestressing of the spring 16 can be adjusted via the threaded rod 32.
Aus der Figur 5 ist zu erkennen, daß die Feder 16 von einem teleskopierbaren Stab 34 durchgriffen ist, der mit seinem unteren Ende gemeinsam mit der Feder 16 an dem Winkelelement 7 und mit seinem oberen Ende an den Gewindestab 32 befestigt ist.It can be seen from FIG. 5 that the spring 16 is penetrated by a telescopic rod 34 which is fastened with its lower end together with the spring 16 to the angle element 7 and with its upper end to the threaded rod 32.
Schließlich ist aus der Figur 4 zu erkennen, daß die --arge 6 über ein L-förmig ausgebildetes Winkelelement 35 mit dem Gebäude verbunden ist, wobei das L- förmige Winkelelement 35 mittels Schrauben 36 mit der Zarge 6 verschraubt ist.Finally, it can be seen from FIG. 4 that the frame 6 is connected to the building via an L-shaped angle element 35, the L-shaped angle element 35 being screwed to the frame 6 by means of screws 36.
Der Einbau des voranstehend beschriebenen Kipptores 1 insbesondere die Mon- tage der Fedem 16 an dem Lenker 9 wird nachfolgend beschrieben:The installation of the tilting gate 1 described above, in particular the assembly days of the Fedem 16 on the handlebar 9 is described below:
Bei der Montage des Kipptores 1 wird nachdem die Führungsschienen 5 und die Zarge 6 am Gebäude befestigt sind, das Torblatt 3 zusammen mit seinem Rahmen 2 mit den Laufrollen 4 in die Führungsschienen 5 eingeführt, woraufhin die Len¬ ker 9 an den Lagerböcken 11 im Bereich der Zarge 6 angeschlagen werden, wo¬ bei zwischen dem Lenker 9 und dem Schenkel 24 des Lagerbocks 11 der Schen¬ kel 20 des Schwingarms 18 angeordnet ist. Der Schwingarm 18 ist bereits werk- seitig mit der Feder 16 verbunden, die an dem Winkelelement 7 angreift und so¬ mit mittelbar mit der Zarge 6 verbunden ist. Über den Gewindestab 32 kann eine erste Vorspannung der Feder 16 eingestellt werden.When installing the tilting gate 1, after the guide rails 5 and the frame 6 are fastened to the building, the door leaf 3 together with its frame 2 with the rollers 4 is inserted into the guide rails 5, whereupon the link 9 on the bearing blocks 11 in the area the frame 6 can be struck, the leg 20 of the swing arm 18 being arranged between the link 9 and the leg 24 of the bearing block 11. The swing arm 18 is already connected at the factory to the spring 16, which engages the angle element 7 and is thus indirectly connected to the frame 6. A first bias of the spring 16 can be set via the threaded rod 32.
Um nunmehr den Lenker 9 mit der Feder 16 für den bestimmungsgemäßen Ge¬ brauch zu verbinden, wird das Torblatt 3 in Richtung der Pfeile 37 in die Öff¬ nungsstellung überführt, wie sie in der Figur 2 dargestellt ist. Hierdurch gelangt das zweite Ende 15 des Lenkers 9 in eine parallele Stellung zu dem Schwingarm 18. Mittels des Bolzens 28, der eine Bohrung 38 (Figur 1) im zweiten Ende 15 des Lenkers 9 durchgreift, wird der Lenker 9 mit seinem zweiten Ende 15 mit dem Schwingarm 18 verbunden. Hierzu wird der Bolzen 28 in die Bohrung 27 der Achse 26 im Schwingarm 18 eingeschraubt. Wird nunmehr das Torblatt aus seiner in Figur 2 dargestellten Öffnungsstellung in seine in Figur 3 dargestellte Schließstellung überführt, so wird der Schwingarm 18 von dem zweiten Ende 15 des Lenkers 9 mitgenommen, so daß die bestimmungsgemäße Vorspannung in der Feder 16 aufgebaut wird, welche beim erneuten Öffnen des Torblattes 3 die Öffnungsbewegung des Torblattes unterstützt. Beim Schließen des Torblattes 3, d.h. beim Überführen des Torblattes aus der in Figur 2 dargestellten Öffnungs¬ stellung in die in Figur 3 dargestellte Schließstellung werden die Fedem 16 ge¬ spannt, so daß die hierzu notwendige Spannkraft der Gewichtskraft des Tor¬ blattes 3 entgegenwirkt und das manuelle Schließen eines derartigen Torblattes auch bei großen Abmessungen und hohen Gewichten ermöglicht.In order now to connect the handlebar 9 to the spring 16 for the intended use, the door leaf 3 is moved in the direction of the arrows 37 into the open position, as shown in FIG. 2. As a result, the second end 15 of the link 9 comes into a parallel position to the swing arm 18. By means of the bolt 28, which passes through a bore 38 (FIG. 1) in the second end 15 of the link 9, the link 9 becomes with its second end 15 connected to the swing arm 18. For this purpose, the bolt 28 is screwed into the bore 27 of the axis 26 in the swing arm 18. If the door leaf is now transferred from its open position shown in FIG. 2 to its closed position shown in FIG. 3, the swing arm 18 is carried along by the second end 15 of the handlebar 9, so that the intended pre-tension is built up in the spring 16, which occurs when it is renewed Opening the door leaf 3 supports the opening movement of the door leaf. When closing the door leaf 3, i.e. When the door leaf is transferred from the open position shown in FIG. 2 to the closed position shown in FIG. 3, the springs 16 are tensioned so that the tension force required for this counteracts the weight of the door leaf 3 and the manual closing of such a door leaf also with large dimensions and high weights.
Durch die voranstehend beschriebene Vorgehensweise beim Einbau derartiger Kipptore 1 wird eine einfache und sichere Montage insbesondere der Schrauben- fedem zum Gewichtsausgleich bereitgestellt, wobei auch die Montage von ent¬ sprechend starken Fede bei größeren Kipptoren beispielsweise mit Doppelfeder- paketen problemlos durchgeführt werden kann. Die Verletzungsgefahr durch zurückspringende Fede wird bei diesem Kipptor erheblich verringert.The procedure described above for installing tilting gates 1 of this type enables simple and safe installation, in particular of the screw provided to compensate for the weight, and the installation of correspondingly strong springs in larger tilting gates, for example with double spring packages, can also be carried out without any problems. The risk of injury due to the spring returning is significantly reduced with this up-and-over door.
Die insbesondere aus dem Lagerbock 11 und dem Schwingarm 18 bestehende Vorrichtung 17 zum Vorspannen der Fedem kann aber auch getrennt von einem derartigen Kipptor Verwendung finden, da es ohne weiteres möglich ist, eine derartige Vorrichtung 17 derart auszubilden, daß bereits bestehende Kipptore da¬ mit nachgerüstet werden können, so daß beim Auswechseln von Fedem, bei¬ spielsweise nach Federbrüchen ebenfalls die Vorteile der Vorrichtung 17 genutzt werden könne. Von besonderem Interesse ist hierbei, daß der Schwingarm 18 ausreichend dimensioniert ist, da durch das Einhängen der Fedem und die Bol¬ zenverbindung zwischen dem Schwingarm 18 und dem Lenker 9 Querkräfte auf¬ treten. Diese Querkräfte können vorzugsweise durch die U-förmige Ausbildung des Schwingarms 18 aufgenommen werden, da diese konstruktive Ausgestaltung des Schwingarms 18 die notwendige Stabilität aufweist. Ferner ist es möglich, bei größeren Kipptoren die Seitenzargen, die Einheit aus Lagerbock und Schwing¬ arm sowie Federpaket vormontiert anzuliefern, so daß am Montageort lediglich noch der Lenker des Torblattes mit dem Schwingarm in voranstehend beschrie¬ bener Weise verbunden werden muß. Hierdurch wird die Montage erheblich er¬ leichtert und es wird insbesondere die bislang mit der Montage verbundene Ge¬ fahr des Aufbringens der Vorspannkraft vermieden. The device 17, in particular consisting of the bearing block 11 and the swing arm 18, for prestressing the springs can also be used separately from such a tilting gate, since it is readily possible to design such a device 17 in such a way that existing tilting gates are retrofitted with it can be, so that when replacing Fedem, for example after spring breaks, the advantages of the device 17 can also be used. It is of particular interest here that the swing arm 18 is dimensioned sufficiently, since 9 lateral forces occur due to the suspension of the springs and the bolt connection between the swing arm 18 and the link 9. These transverse forces can preferably be absorbed by the U-shaped design of the swing arm 18, since this design of the swing arm 18 has the necessary stability. In the case of larger tilting gates, it is also possible to deliver the side frames, the unit consisting of the pedestal and the swing arm and spring assembly preassembled, so that only the handlebar of the door leaf has to be connected to the swing arm in the manner described above at the installation site. This considerably facilitates assembly and, in particular, the risk of applying the pretensioning force previously associated with the assembly is avoided.
