Eine derartige Kabine ist bereits aus der JP 07009853 bekannt.Such a cabin is already out of the JP07009853 known.

Es ist eine Vielzahl verschiedener Türen und Schwenktüren für derartige Kabinen bekannt, die jedoch alle den Nachteil aufweisen, schwer montierbar zu sein, eine aufwendige Befestigungskonstruktion zu benötigen oder aber instabil mit der Kabine verbunden zu sein.There are a variety of different doors and swing doors known for such cabins, but all have the disadvantage of being difficult to install, to require a complex mounting structure or unstable connected to the cabin.

Besonders im letzten Fall besteht die enorme Gefahr, daß sich die Türe aufgrund von Schwingungen und Erschütterungen, die beim Betrieb des Krans, des Baggers oder dergleichen auftreten, von der Kabine löst.Especially in the latter case, there is an enormous risk that the door due to vibrations and vibrations that occur during operation of the crane, the excavator or the like, dissolves from the cabin.

Aufgabe der Erfindung ist es eine Kabine mit einer Schwenktüre vorzuschlagen, welche einfach und kostengünstig herzustellen und zu montieren ist und trotzdem sicher mit der Kabine verbunden und sicher zu bedienen ist.The object of the invention is to propose a cabin with a swing door, which is simple and inexpensive to manufacture and assemble and still safely connected to the cabin and safe to use.

Diese Aufgabe wird dadurch gelöst, daß die Schwenktüre im wesentlichen über ein einziges Traggelenk mit der Kabine verbunden ist.This object is achieved in that the swinging door is connected to the car essentially via a single ball joint.

Hierdurch wird die Türe sicher, aber dennoch beweglich mit der Kabine verbunden.As a result, the door is securely but still connected to the cabin movable.

Es hat sich dabei als sehr vorteilhaft erwiesen, wenn das Traggelenk am oberen Ende des Türausschnittes bzw. dem oberen Ende der Türe angeordnet ist.It has proven to be very advantageous if the ball joint is arranged at the upper end of the door cutout or the upper end of the door.

Ebenfalls als vorteilhaft hat es sich erwiesen, wenn das Traggelenk einstellbar, insbesondere in vertikaler Richtung einstellbar ausgebildet ist.Also, it has proved to be advantageous if the support joint is adjustable, in particular in the vertical direction is adjustable.

Hiermit lassen sich Fertigungstoleranzen sowie verschleißbedingte Abweichungen problemlos ausgleichen.This makes it easy to compensate for manufacturing tolerances and wear-related deviations.

Eine weitere, sehr vorteilhafte Fortbildung der Erfindung ist auch darin zu sehen, daß wenigstens eine weitere Führung zwischen Türe und Kabine angeordnet ist.Another, very advantageous development of the invention is also to be seen in that at least one further guide between the door and the cabin is arranged.

Damit wird die Türe gegenüber der Kabine stabilisiert.This stabilizes the door opposite the cab.

Es hat sich dabei als sehr vorteilhaft erwiesen, wenn die weitere Führung als Hebel ausgebildet ist.It has proved to be very advantageous if the further guide is designed as a lever.

Eine ebenfalls sehr vorteilhafte Ausgestaltung der Erfindung liegt auch darin, daß das Traggelenk und die weitere Führung derart ausgebildet sind, daß diese zusammen die Bewegungsbahn der Türe definieren.A likewise very advantageous embodiment of the invention lies in the fact that the support joint and the further guide are designed such that they together define the path of movement of the door.

Durch diese Ausgestaltungen können sehr genaue Bewegungsbahnen definiert werden, wobei die Türe sicher gehalten wird.By these embodiments, very accurate trajectories can be defined, the door is held securely.

Es hat sich auch als sehr vorteilhaft erwiesen, wenn am unteren Ende der Tür bzw. des Türausschnittes eine Führung zum Stabilisieren der Türe vorgesehen ist.It has also proved to be very advantageous if a guide for stabilizing the door is provided at the lower end of the door or the door cutout.

Hiermit wird die Türe nochmals gehalten.This will hold the door again.

Eine sehr vorteilhafte Fortbildung der Erfindung liegt auch darin, daß das Traggelenk und die Führungen derart angeordnet sind, daß die Türe beim Öffnen und Schließen eine Bewegungsbahn zu durchlaufen vermag, die wenigstens annährend einem Abschnitt eines Parallelogramms entspricht.A very advantageous development of the invention lies in the fact that the ball joint and the guides are arranged such that the door when opening and closing is able to traverse a trajectory which corresponds at least approximately to a portion of a parallelogram.

Ebanfalls als sehr vorteilhaft hat es sich erwiesen, wenn das Traggelenk und die Führungen derart angeordnet und ausgebildet sind, daß sie ermöglichen, daß die Türe wenigstens annährend mit einer senkrecht gerichteten Bewegung auf den Türausschnitt auftrifft.Ebanfalls has proved to be very advantageous when the ball joint and the guides are arranged and designed such that they allow the door to impinge on the door opening at least approximately with a vertically directed movement.

Beide Ausgestaltungen stellen ein sicheres Schließen der Türe sicher und sorgen aber dennoch dafür, daß der Türausschnitt möglichst gut von der Türe im geöffneten Zustand freigegeben wird.Both embodiments ensure a safe closing of the door and yet ensure that the door cutout is released as well as possible from the door in the open state.

Eine weitere, erfindungsgemäß sehr vorteilhafte Ausgestaltung der Erfindung liegt auch darin, daß die Türe wenigstens eine Verriegelungseinrichtung aufweist.Another, according to the invention very advantageous embodiment of the invention is also the fact that the door has at least one locking device.

Mit 1 ist in Fig. 1 eine Kabine zur Verwendung bei einem Kran, Bagger oder dgl. mit einer Schwenktüre 2 bezeichnet. Die Türe 2 ist im Bereich des oberen Randes mittels einem an einem Tragarm 3 angeordneten Traggelenk 4 mit der Kabine 1 verbunden. Das Traggelenk 4 nimmt das Gewicht der Türe auf. Das von der Türe 2 abgewandte Ende des Tragarmes 3 ist im Bereich des Türausschnittes 5 gelenkig mit der Kabine 1 verbunden.With 1 is in Fig. 1 a cabin for use in a crane, excavator or the like. With a swing door 2. The door 2 is connected to the car 1 in the region of the upper edge by means of a support joint 4 arranged on a support arm 3. The ball joint 4 takes on the weight of the door. The remote from the door 2 end of the support arm 3 is pivotally connected to the cabin 1 in the region of the door cutout 5.

Zusätzlich ist ebenfalls im Bereich des oberen Randes der Türe 2 ein Führungshebel 6 angeordnet, der wie der Tragarm 3 sowohl gelenkig mit der Türe 2 als auch mit der Kabine 1 verbunden ist. Der Tragarm 3 und der Führungshebel 6 definieren zusammen die Bewegungsbahn 7 der Türe 2 beim Öffnen und Schließen. Zur Ausrichtung der Türe 2 kann der Führungshebel 6 in seiner Länge verstellt werden. Dazu ist der Hebel 6 aus zwei lösbar miteinander verbundenen Teilen 8 und 9 aufgebaut.In addition, a guide lever 6 is also arranged in the region of the upper edge of the door 2, which, like the support arm 3, is connected both to the door 2 and to the cabin 1 in an articulated manner. The support arm 3 and the guide lever 6 together define the path of movement 7 of the door 2 during opening and closing. For aligning the door 2, the guide lever 6 can be adjusted in its length. For this purpose, the lever 6 is composed of two detachably interconnected parts 8 and 9.

Über ein Langloch 10 im Teil 8 lässt sich die Länge des Führungshebels 6 einstellen.About a slot 10 in Part 8, the length of the guide lever 6 can be adjusted.

Am unteren Ende der Türe 2 sind zwei weitere Führungshebel 11 und 12 vorgesehen, welche die Türe 2 an ihrem unteren Ende zusätzlich fixieren und stabilisieren. Wenigstens einer der beiden Hebel 11 und 12 ist genauso wie der Führungshebel 6 längenverstellbar ausgebildet.At the lower end of the door 2, two further guide levers 11 and 12 are provided, which additionally fix the door 2 at its lower end and stabilize. At least one of the two levers 11 and 12 is designed to be adjustable in length as well as the guide lever 6.

Die durch die Führungshebel 6, 11 und 12 sowie der Tragarm 3 definierte Bewegungsbahn 7 ist derart ausgebildet, daß die Türe wenigstens annährend senkrecht auf den Türausschnitt 5 trifft. Dadurch werden eventuell vorgesehene Gummidichtungen nur in Dichtungsrichtung beansprucht und nicht durch auftretende seitliche Kräfte deformiert.The defined by the guide lever 6, 11 and 12 and the support arm 3 trajectory 7 is formed such that the door meets at least approximately perpendicular to the door opening 5. As a result, any intended rubber seals are only claimed in the sealing direction and not deformed by lateral forces occurring.

An den beiden Längskanten 13 und 14 der Türe 2 ist jeweils etwa in der Mitte je eine Verriegelungseinrichtung 15 vorgesehen, welche in Gegenlager 16 einzugreifen vermögen, die entsprechende Positionen am Türausschnitt 5 einnehmen.At the two longitudinal edges 13 and 14 of the door 2 each have a locking device 15 is provided approximately in the middle, which are able to intervene in abutment 16, occupy the corresponding positions on the door opening 5.

Beim Verschließen der Türe 2, wobei die Verriegelungseinrichtungen 15 in die Gegenlager 16 eingreifen, wird die Türe 2 senkrecht gegen den Türausschnitt 5 gezogen und dort gesichert.When closing the door 2, wherein the locking means 15 engage in the abutment 16, the door 2 is pulled vertically against the door cut-5 and secured there.

Es besteht die Möglichkeit, daß eine weitere Verrieglungsvorrichtung 17 im Bereich des unteren Endes der Türe 2 vorgesehen sein kann, welche in ein Gegenlager 17a eingreift, die Türe 2 im geöffneten Zustand gegenüber der Kabine 1 fixiert und dadurch verhindert, daß die Türe 2 versehentlich zufällt. Diese Fixierung im geöffneten Zustand sorgt auch dafür, daß etwaig auftretende Schwingungen und Vibrationen keine schädlichen Auswirkungen auf die Türe 2 ausüben können.There is the possibility that a further Verrieglungsvorrichtung 17 may be provided in the region of the lower end of the door 2, which engages in an abutment 17a, the door 2 fixed in the open state relative to the car 1 and thereby prevents the door 2 accidently falls , This fixation in the open state also ensures that any vibrations and vibrations occurring can not exert any harmful effects on the door 2.

Etwa in der Mitte der Türe 2 kann eine Betätigungseinrichtung 18 vorgesehen sein, welche -wie in den Zeichnungen dargestellt- als drehbeweglicher Griff ausgebildet sein kann.Approximately in the middle of the door 2, an actuating device 18 may be provided, which -as shown in the drawings-can be designed as a rotatable handle.

Diese Betätigungseinrichtung 18 betätigt beim Öffnen der Türe 2 die Verriegelungseinrichtungen 15, wodurch die Verbindung zwischen Verriegelungseinrichtung 15 und Gegenlager 16 gelöst wird. Beim Schließen der Türe 2 wird dagegen die Verriegelungseinrichtung 17 betätigt, wodurch die Fixierung gelöst wird und die Türe 2 geschlossen werden kann.This actuator 18 operates when opening the door 2, the locking means 15, whereby the connection between locking device 15 and abutment 16 is released. When closing the door 2, however, the locking device 17 is actuated, whereby the fixation is released and the door 2 can be closed.

Die Betätigungseinrichtung 18 kann dabei mittels Zugstangen 19 und 20 auf die Verriegelungseinrichtungen 15 und 17 wirken. Es ist aber auch denkbar, daß beliebige andere mechanische Verbindungen zwischen der Betätigungseinrichtung 18 und den Verriegelungseinrichtungen 15 und 17 vorgesehen sein können.The actuating device 18 can act on the locking devices 15 and 17 by means of tie rods 19 and 20. But it is also conceivable that any other mechanical connections between the actuator 18 and the locking means 15 and 17 may be provided.

Die Betätigungseinrichtung 18 kann zur Verbindung mit den Zugstangen 19 und 20 eine Kulissenscheibe 21 aufweisen, in welche die Zugstangen 19 und 20 eingreifen.The actuator 18 may have a link plate 21 for connection to the tie rods 19 and 20, in which the tie rods 19 and 20 engage.

Mit Hilfe der Kulissenscheibe 21 kann sichergestellt werden, daß nur die jeweils gewünschten Verriegelungseinrichtungen 15 und 17 betätigt werden, während die anderen freigegeben sind.With the help of the crank disc 21 can be ensured that only the respectively desired locking means 15 and 17 are actuated while the others are released.

Die Betätigungseinrichtung 18 kann auch ein Schloß 22 aufweisen, welches die Betätigungseinrichtung 18 vor unbefugter Benutzung zu sichern vermag.The actuator 18 may also include a lock 22 which is capable of securing the actuator 18 against unauthorized use.

Auf der Innenseite der Türe 2 können den Verriegelungseinrichtungen 15 Notbetätigungen 23 zugeordnet sein, welche es ermöglichen die Türe 2 auch dann von innen zu öffnen, wenn die Betätigungseinrichtung 18 durch das Schloß 22 blockiert ist.On the inside of the door 2, the locking devices 15 can be associated with emergency actuations 23, which make it possible to open the door 2 from the inside even when the actuator 18 is blocked by the lock 22.

Dazu kann die Kulissenscheibe 21 derart ausgeführt sein, daß die Zugstangen 19 so viel Spiel in der Kulissenscheibe 21 haben, daß die Notöffnung der Verriegelungseinrichtungen 15 nicht behindert ist.For this purpose, the link plate 21 may be designed such that the tie rods 19 have so much game in the link plate 21 that the emergency opening of the locking means 15 is not hindered.
