On the rocker lever (15) engages, between its point of articulation on the frame and its point of connection to the door leaf (33), a connecting rod (21), the lower end of which is guided on the door frame so as to be vertically displaceable. The lower end of the rod (21) is under the effect of a spring (26) which presses it upwards. <IMAGE>

Description

Die Erfindung betrifft ein Schwingtor, insbesondere für Ga­ragen, mit einem im Bereich seines unteren Endes an einem Rahmen geführten Torflügel, an dem beidseitig je ein Schwinghebel angreift, der im Bereich der Oberkante des Rah­mens angelenkt ist.The invention relates to a swing gate, in particular for garages, with a gate wing guided in the region of its lower end on a frame, to which a swing lever engages on both sides, which is articulated in the region of the upper edge of the frame.

Schwingtore dieser Art sind bekannt. Ihr Vorteil besteht darin, daß der Torflügel beim Öffnen des Tores nicht über die Bauflucht ausschwenkt.Up-and-over doors of this type are known. Your advantage is that the gate wing does not swing out over the building line when opening the gate.

Bei einem bekannten Schwingtor dieser Art (DE-U 81 06 873) ist der Schwinghebel an dem Torflügel bzw. einem mit diesem verbundenen Element angelenkt. Zusammen mit einer Rollenfüh­rung im unteren Bereich des Torflügels bestimmt der Gelenk­punkt des Schwinghebels die Kinematik des Torflügels. Das obere Ende des Torflügels bewegt sich etwa senkrecht zur Ebene des Rahmens nach hinten. Die Oberkante des Rahmens führt jedoch keine exakte geradlinige Bewegung aus.In a known swing gate of this type (DE-U 81 06 873), the swing lever is articulated on the gate wing or an element connected to it. Together with a roller guide in the lower area of the gate wing, the pivot point of the rocker arm determines the kinematics of the gate wing. The upper end of the gate wing moves approximately perpendicular to the plane of the frame to the rear. However, the top edge of the frame does not make an exact straight line movement.

Ebenfalls bekannt ist ein Schwingtor (DE-A 33 24 837), bei dem der Torflügel im Bereich seines oberen und unteren Endes an je einem Paar von Laufschienen geführt ist.A swing gate (DE-A 33 24 837) is also known, in which the gate wing is guided in the region of its upper and lower ends on a pair of running rails.

Ebenfalls bekannt ist ein Schwingtor dieser Art (DE-U 87 15 917), das einen automatischen Antrieb aufweist.A swing gate of this type is also known (DE-U 87 15 917), which has an automatic drive.

Zum Gewichtsausgleich ist bei Schwingtoren dieser Art häufig eine Zugfeder vorhanden, die beidseits am Torflügel in einem gewissen Abstand von dem Anlenkpunkt des Schwinghebels an­greift. Das andere Ende der Zugfeder ist im Bereich der Oberseite des Torrahmens befestigt. Diese Schraubenfeder liegt frei im Raum.To compensate for the weight of up-and-over doors of this type, there is often a tension spring which acts on both sides of the gate wing at a certain distance from the articulation point of the swinging lever. The other end of the tension spring is fastened in the area of the top of the goal frame. This coil spring is free in the room.

Weiterhin bekannt ist ein Garagentor mit horizontalen Lauf­schienen (DE-C2 30 14 414). Die Schwinghebel sind hierbei als Teleskoprohre mit einem Innenstab ausgebildet. An den Schwinghebeln greift je eine Gasfeder zum Öffnen des Tores an. Das durch die Gasfedern bewirkte Drehmoment führt zu einem Verkanten der Teleskopstange in dem Teleskoprohr und damit zu einer Schwergängigkeit der Öffnung.Also known is a garage door with horizontal tracks (DE-C2 30 14 414). The rocker arms are designed as telescopic tubes with an inner rod. A gas spring acts on the swing levers to open the gate. The torque caused by the gas springs leads to a tilting of the telescopic rod in the telescopic tube and thus to a sluggish opening.

Der Erfindung liegt die Aufgabe zugrunde, ein Schwingtor zu schaffen, das bei einfachem Aufbau leichter und kostengün­stiger herstellbar ist und leichtgängiger zu öffnen ist.The invention has for its object to provide a swing gate that is easier and cheaper to manufacture with a simple structure and is easier to open.

Zur Lösung dieser Aufgabe schlägt die Erfindung ein Schwing­tor mit den Merkmalen des Anspruchs 1 vor.To achieve this object, the invention proposes a swing gate with the features of claim 1.

Anstelle der Teleskoprohre, die verkanten können und schwer­gängig sind, greift nach der Erfindung der durch Federkraft in Öffnungsrichtung beaufschlagte Schwinghebel an einer Rol­ le des Torflügels an. Der Längenausgleich kann durch Abrol­len der Rolle an der Laufschiene erfolgen. Das Schwingtor ist nicht nur einfacher aufgebaut, sondern auch leichtgängi­ger.Instead of the telescopic tubes, which can tilt and are stiff, according to the invention, the rocker arm acted upon by spring force in the opening direction engages a roller le of the gate wing. The length can be adjusted by rolling the roller on the running rail. The up-and-over door is not only simpler in construction, but also smoother.

In Weiterbildung der Erfindung kann vorgesehen sein, daß an dem Schwinghebel ein Ende einer Stange angelenkt ist, deren anderes Ende am Rahmen verschiebbar geführt und unter Feder­wirkung in Richtung nach oben beaufschlagt ist. Dadurch wird es möglich, auf die Verwendung teuerer Gasfedern zu verzich­ten. Es wird möglich, die Feder seitlich am Torrahmen anzu­ordnen, so daß sie nicht mehr seitlich am Schwinghebel zu­gänglich ist. Die durch die Feder bewirkte Kraft wird über die starre Stange, die als Schubstange wirkt, auf den jewei­ligen Schwinghebel übertragen. Als Federn können insbeson­dere Zugfedern verwendet werden, für die ausreichend Platz vorhanden ist, so daß das von der Erfindung vorgeschlagene Schwingtor insbesondere bei großen Toren, beispielsweise Doppelgaragen, verwendbar ist.In a further development of the invention, it can be provided that one end of a rod is articulated on the rocker arm, the other end of which is slidably guided on the frame and acted upon by spring action in the upward direction. This makes it possible to dispense with the use of expensive gas springs. It becomes possible to arrange the spring laterally on the goal frame so that it is no longer accessible laterally on the rocker arm. The force caused by the spring is transmitted to the respective rocker arm via the rigid rod, which acts as a push rod. Tension springs in particular can be used as springs, for which there is sufficient space so that the up-and-over door proposed by the invention can be used in particular with large gates, for example double garages.

Die Erfindung schlägt in Weiterbildung vor, daß die Stange bei geschlossenem Torflügel etwa senkrecht verläuft. Die Stange liegt also unmittelbar benachbart zu den senkrechten Holmen des Torrahmens.The invention proposes in a further development that the bar runs approximately vertically when the gate leaf is closed. The bar is therefore immediately adjacent to the vertical bars of the goal frame.

Besonders günstig ist es, wenn zur Federbeaufschlagung des Schwingtors mindestens eine Zugfeder vorgesehen ist, die in einem Hohlprofil des Torrahmens untergebracht ist. Auf diese Weise ist die Zugfeder geschützt und abgeschlossen unterge­bracht, so daß sie nicht stören kann. Außerdem wird durch die Unterbringung in einem sowieso vorhandenen Hohlprofil des Torrahmens der Platzbedarf nicht vergrößert.It is particularly expedient if at least one tension spring is provided for spring loading of the swinging gate and is accommodated in a hollow profile of the goal frame. In this way, the tension spring is protected and housed so that it cannot interfere. In addition, the space requirement is not increased by the accommodation in an already existing hollow profile of the goal frame.

Für besonders schwere Torflügel schlägt die Erfindung vor, an jeder Seite des Torflügels zwei Schraubenfedern anzuord­nen, die beide hintereinander in dem Hohlprofil unterge­ bracht sind. Dabei ist erfindungsgemäß vorgesehen, daß jede Schraubenfeder an einem ihrer Enden an einem Zugelement, insbesondere einem Zugseil angreift, das durch die jeweils andere Feder in deren Längsachse hindurch verläuft. Auf die­se Weise werden die beiden Schraubenfedern räumlich hinter­einander angeordnet, während sie funktionell parallelge­schaltet sind. Dies führt zu einer Verstärkung der Feder­kraft, ohne daß der Platzbedarf steigt, wie dies bei Verwen­dung einer stärkeren Feder erforderlich wäre.For particularly heavy gate leaves, the invention proposes to arrange two coil springs on each side of the gate leaf, both of which are placed one behind the other in the hollow profile are brought. It is provided according to the invention that each helical spring engages at one of its ends on a tension element, in particular a tension cable, which runs through the other spring in its longitudinal axis. In this way, the two coil springs are spatially arranged one behind the other while they are functionally connected in parallel. This leads to an increase in the spring force without increasing the space requirement, as would be required if a stronger spring were used.

In Weiterbildung der Erfindung kann vorgesehen sein, daß die Stange an ihrem unteren Ende mit einem Ansatz versehen ist, der durch einen Schlitz des Hohlprofils des Rahmens hin­durchgreift. Dieser Ansatz wird an der Außenseite des Pro­fils mit mindestens einer Rolle geführt. An dem Ansatz greift innerhalb des Hohlprofils die mindestens eine Zugfe­der an. Da sich die Zugstange auch verschwenkt, wenn ihr unteres Ende sich geradlinig bewegt, führt dies zu einer Verschwenkung des Ansatzes, was durch die Führung mit Hilfe der Rollen nur an der Außenseite des Hohlprofils ermöglicht wird. Die Zugfeder erzeugt eine Kraftkomponente, die dafür sorgt, daß die Rolle immer an der Außenseite anliegt.In a further development of the invention it can be provided that the rod is provided at its lower end with an extension which engages through a slot in the hollow profile of the frame. This approach is performed on the outside of the profile with at least one roller. At least one tension spring acts on the shoulder within the hollow profile. Since the tie rod also pivots when its lower end moves in a straight line, this leads to a pivoting of the shoulder, which is only possible on the outside of the hollow profile due to the guide using the rollers. The mainspring creates a force component that ensures that the roller is always on the outside.

Erfindungsgemäß kann vorgesehen sein, daß die Schubstange an dem Schwinghebel in einem von dem Anlenkpunkt am Rahmen be­trachteten Abstand von etwa einem Viertel bis etwa einem Drittel der Länge des Schwinghebels angreift. Dieser Abstand bestimmt, wie weit sich das untere Ende der Schubstange nach oben bewegen muß, damit die Tür vollständig geöffnet wird.According to the invention it can be provided that the push rod engages the rocker arm at a distance from the pivot point on the frame of about a quarter to about a third of the length of the rocker arm. This distance determines how far the lower end of the push rod has to move up so that the door is fully opened.

Weitere Merkmale, Einzelheiten und Vorzüge der Erfindung ergeben sich aus der folgenden Beschreibung bevorzugter Aus­führungsformen der Erfindung sowie anhand der Zeichnung. Hierbei zeigen:

  • Fig. 1 schematisch die Seitenansicht einer Ausfüh­rungsform bei geschlossenem Tor;
  • Fig. 2 eine Seitenansicht bei teilweise geöffnetem Tor;
  • Fig. 3 eine Teilansicht der Anordnung zweier Zugfe­dern;
  • Fig. 4 eine perspektivische Detailansicht des unte­ren Endes eines Rahmenholmes.
Further features, details and advantages of the invention will become apparent from the following description of preferred embodiments of the invention and from the drawing. Here show:
  • Figure 1 shows schematically the side view of an embodiment with the gate closed.
  • Fig. 2 is a side view with the gate partially open;
  • 3 shows a partial view of the arrangement of two tension springs;
  • Fig. 4 is a detailed perspective view of the lower end of a frame spar.

Der Rahmen des in Fig. 1 schematisch in geschlossenem Zu­stand dargestellten Garagenschwingtores enthält zwei Seiten­holme 11, von denen in der Figur natürlich nur einer zu se­hen ist. Die Seitenholme 11 sind im Bereich der Oberseite 12 des Tores durch einen oberen Holm und im Bereich der Unter­seite 13 des Tores durch einen unteren Holm miteinander ver­bunden. Dadurch entsteht ein rechteckiger Rahmen.The frame of the overhead garage door shown schematically in FIG. 1 contains two side rails 11, of which only one can of course be seen in the figure. The side rails 11 are connected to one another in the area of the upper side 12 of the door by an upper bar and in the area of the lower side 13 of the door by a lower bar. This creates a rectangular frame.

An der Oberseite des Rahmens sind etwa horizontal verlaufen­de Laufschienen 30 angeordnet. In diesen Laufschienen 30 wird der obere Bereich des Torflügels 33 mit Hilfe von Rol­len 35 geführt.Runners 30 which run approximately horizontally are arranged on the top of the frame. The upper region of the gate leaf 33 is guided in these tracks 30 with the aid of rollers 35.

Im Bereich der Oberseite 12 des Rahmens ist an jeder Seite, d.h. etwa im oberen Bereich jedes Seitenholmes 11, eine La­sche 14 befestigt, beispielsweise angeschweißt oder ange­schraubt. An der Lasche 14 ist jeweils ein Schwinghebel 15 mit Hilfe einer Gelenkachse 16 angelenkt. Jeder Schwingebel kann also um die Gelenkachse 16 verschwenkt werden. Im Be­reich seines freien indes ist der Schwinghebel 15 mit einer Laufschiene 32 versehen. Eine Lasche 18 ist an der Seiten­kante des zwischen den Seitenholmen 11 befindlichen Torflü­gels befestigt, beispielsweise angeschraubt oder ange­schweißt. An der Lasche 18 ist eine Rolle 31 angeordnet. Diese Rolle 31 greift in die Laufschiene 32 ein, die im Bereich des Endes des Schwinghebels 15 in dessen Längsrich­tung verläuft. Der Grund hierfür ergibt sich durch die Tat­sache, daß der Ort der Rolle 31 nicht einen Kreis um die Gelenkachse 16 ausführt. Vielmehr ändert sich der Abstand der Rolle 31 von der Gelenkachse 16 bei der Öffnungsbewegung des Tors. Dieser Ausgleich wird durch das Eingreifen der Rolle 31 in der Laufschiene 32 ermöglicht. Die Laufrolle 31 kann selbstverständlich nur in Längsrichtung der Laufschiene 32 ausweichen kann, nicht jedoch in Querrichtung.In the area of the top 12 of the frame, a tab 14 is fastened, for example welded or screwed, on each side, ie approximately in the upper area of each side member 11. A rocker arm 15 is articulated on the bracket 14 with the aid of an articulated axis 16. Each rocker arm can thus be pivoted about the hinge axis 16. In the area of its free, however, the rocker arm 15 is provided with a running rail 32. A tab 18 is attached to the side edge of the gate leaf located between the side rails 11, for example screwed or welded. A roller 31 is arranged on the tab 18. This roller 31 engages in the running rail 32, which extends in the longitudinal direction in the region of the end of the rocker arm 15. The reason for this arises from the fact that the location of the roller 31 does not make a circle around the hinge axis 16. Rather, the distance of the roller 31 from the hinge axis 16 changes during the opening movement of the gate. This compensation is made possible by the engagement of the roller 31 in the running rail 32. The roller 31 can of course only avoid in the longitudinal direction of the track 32, but not in the transverse direction.

Der Torflügel ist im Bereich seines in geschlossenem Zustand unteren Endes an den Seitenholmen 11 des Rahmens geführt, beispielsweise dadurch, daß dort jeweils eine Rolle angeord­net ist, die in Laufschienen geführt ist. Wird das untere Ende des Torflügels aus der geschlossenen Stellung nach oben bewegt, so bewegt sich sein oberes Ende nach hinten bzw. innen, wobei der Schwinghebel 15 in Fig. 1 im Gegenuhrzei­gersinn verschwenkt wird. Diese Kinematik ist bekannt.The gate wing is guided in the region of its lower end in the closed state on the side rails 11 of the frame, for example in that a roller is arranged there, which is guided in running rails. If the lower end of the gate wing is moved upwards from the closed position, its upper end moves backwards or inwards, the rocking lever 15 being pivoted counterclockwise in FIG. 1. This kinematics is known.

An dem Schwinghebel 15 ist zwischen seinen beiden Gelenkach­sen 16 und 17 seitlich eine Lasche 19 befestigt, beispiels­weise angeschweißt. An der Lasche 19 greift das obere Ende 20 einer im Querschnitt runden Stange 21 gelenkig an. Dies geschieht beispielsweise durch einen Bolzen 22, der durch eine Öffnung im oberen Ende 20 der Stange 21 und eine ent­sprechende Öffnung in der Lasche 19 hindurchgreift. In ge­schlossenem Zustand erstreckt sich die Stange 21 senkrecht, d.h. parallel zum Seitenholm 11 des Torrahmens. Das untere Ende 23 der Stange 21 weist einen sich quer zur Längsrich­tung der Stange 21 erstreckenden Ansatz 24 auf. Der Ansatz 24 kann beispielsweise durch ein Flacheisen gebildet sein, das an das untere Ende der Stange 23 angeschweißt ist. Der Ansatz 24 erstreckt sich durch einen in Fig. 1 nicht sicht­baren Schlitz in das Innere des Seitenholmes 11. Dort be­sitzt der Ansatz 24 ein Loch 25. An diesem innerhalb des Seitenholms 11 befindlichen Teil des Ansatzes 24 greift eine Zugfeder 26 an, deren anderes Ende am oberen Ende 12 des entsprechenden Seitenholms 11 befestigt ist. Diese Zugfeder 26 beaufschlagt das untere Ende 23 der Stange 21 nach oben. Wird nun der Torflügel etwas geöffnet, so zieht die Feder 26 das untere Ende 23 der Stange 21 nach oben, so daß das obere Ende 20 der Stange 21 den Schwinghebel 15 nach hinten und oben schiebt. Diese Bewegung wird auf das Ende des Schwing­hebels 15 übertragen, der durch Angreifen an der Rolle 31 des Torflügels diesen öffnet. In vollständig geöffnetem Zu­stand des Torflügels liegt die Rolle 31 etwa horizontal zur Gelenkachse 16. Das untere Ende 23 der Stange 21 ist um eine bestimmte Strecke nach oben verschoben worden, die bei­spielsweise in der Größenordnung von 30 cm liegt. Den Zu­stand des Torflügels 33 bei teilweiser Öffnung zeigt Fig. 2. Hier hat die Stange 21 den Schwinghebel 15 bereits etwas aufgeschwenkt, wobei gleichzeitig der Torflügel 33 etwas geöffnet ist. Die am Ende der Lasche 18 angeordnete Lauf­rolle 31 befindet sich nicht mehr am Ende der Laufschiene 32, sondern bereits im mittleren Bereich. Bei vollständiger Öffnung des Torflügels 33 befindet sich die Laufrolle 31 am Ende der Laufschiene 32 des Schwinghebels 15.On the rocker arm 15 a tab 19 is laterally attached, for example welded, between its two hinge axes 16 and 17. The upper end 20 of a rod 21, which is round in cross section, articulates on the tab 19. This is done, for example, by a bolt 22 which extends through an opening in the upper end 20 of the rod 21 and a corresponding opening in the tab 19. In the closed state, the rod 21 extends vertically, ie parallel to the side rail 11 of the goal frame. The lower end 23 of the rod 21 has a shoulder 24 which extends transversely to the longitudinal direction of the rod 21. The extension 24 can be formed, for example, by a flat iron that is welded to the lower end of the rod 23. The extension 24 extends through a slot (not visible in FIG. 1) into the interior of the side rail 11. There the extension 24 has a hole 25 Part of the extension 24 located on the side rail 11 engages a tension spring 26, the other end of which is attached to the upper end 12 of the corresponding side rail 11. This tension spring 26 acts on the lower end 23 of the rod 21 upwards. If the gate wing is now opened somewhat, the spring 26 pulls the lower end 23 of the rod 21 upward, so that the upper end 20 of the rod 21 pushes the rocker arm 15 backwards and upwards. This movement is transmitted to the end of the rocker arm 15, which opens this by engaging the roller 31 of the gate wing. In the fully opened state of the gate leaf, the roller 31 lies approximately horizontally to the hinge axis 16. The lower end 23 of the rod 21 has been displaced upwards by a certain distance, which is, for example, of the order of 30 cm. The state of the gate leaf 33 with partial opening is shown in FIG. 2. Here, the rod 21 has already pivoted the rocker arm 15 somewhat open, and at the same time the gate leaf 33 is somewhat open. The roller 31 arranged at the end of the tab 18 is no longer located at the end of the running rail 32, but already in the middle region. When the gate leaf 33 is fully opened, the roller 31 is located at the end of the running rail 32 of the rocker arm 15.

Das untere Ende des Torflügels 43 wird durch eine Laufrolle 34 geführt, die an der Innenseite des Seitenholms 11 des Torrahmens angreift. Das obere Ende des Torflügels 33 wird durch eine weitere Rolle 35 geführt, die in der Laufschiene 30 läuft. Es versteht sich von selbst, daß auf beiden Seiten des Torflügels bzw. des Rahmens jeweils eine derartige aus Schwinghebel 15, Stange 21 und Laufschiene 30 bestehende Einrichtung vorgesehen ist.The lower end of the gate leaf 43 is guided by a roller 34 which engages on the inside of the side rail 11 of the goal frame. The upper end of the gate leaf 33 is guided by a further roller 35 which runs in the running rail 30. It goes without saying that such a device consisting of rocker arm 15, rod 21 and running rail 30 is provided on both sides of the gate wing or frame.

Um bei schweren Torflügeln ausreichend Federkraft zur Ver­fügung zu stellen, wäre es denkbar, eine besonders kräftige Feder in dem Seitenholm 11 anzuordnen. Stärkere Federn haben jedoch auch einen größeren Windungsdurchmesser, so daß ein Seitenholm 11 mit größerem Innenraum verwendet werden müßte. Um dennoch mit den kleineren Abmessungen der üblichen Sei­tenholme 11 auszukommen, schlägt die Erfindung vor, zwei Zugfedern 26 zu verwenden, die parallel wirken. Aus diesem Grunde wird eine Feder 26 an dem Ansatz 24 und eine zweite Zugfeder 26 an der Oberseite 12 des Seitenholms 11 befe­stigt. Jede Zugfeder 26 ist kürzer als die halbe Länge des Seitenholmes 11. Zur Verbindung mit dem jeweils anderen Punkt wird infolgedessen ein Zugseil 27 verwendet, siehe Fig. 3. Jedes Zugseil 27 erstreckt sich in der Längsachse durch die Windungen derjenigen Zugfeder 26, mit der es nicht verbunden ist. Dadurch wird funktionell eine Parallelschal­tung der beiden Zugfedern 26 erreicht, wobei die Zugfedern 26 räumlich jedoch hintereinander angeordnet sind. Selbst­verständlich läßt sich auf diese Weise auch die Parallel­schaltung von mehr als zwei Zugfedern erreichen.In order to provide sufficient spring force for heavy gate leaves, it would be conceivable to arrange a particularly strong spring in the side rail 11. However, stronger springs also have a larger coil diameter, so that a Side spar 11 with a larger interior space would have to be used. In order to get by with the smaller dimensions of the usual side rails 11, the invention proposes to use two tension springs 26 which act in parallel. For this reason, a spring 26 is attached to the neck 24 and a second tension spring 26 to the top 12 of the side member 11. Each tension spring 26 is shorter than half the length of the side rail 11. A tension cable 27 is consequently used for connection to the other point, see FIG. 3. Each tension cable 27 extends in the longitudinal axis through the turns of the tension spring 26 with which it is is not connected. Functionally, a parallel connection of the two tension springs 26 is achieved, the tension springs 26 being spatially arranged one behind the other. Of course, the parallel connection of more than two tension springs can also be achieved in this way.

Fig. 4 zeigt vergrößert und perspektivisch das untere Ende 23 der Stange 21. An dem unteren Ende ist der Ansatz 24 an­geschweißt, beispielsweise ein Flacheisen. Der Ansatz 24 greift durch den Schlitz 36 des Hohlprofils 37 des Seiten­holmes 11 des Torrahmens. Innerhalb des Hohlprofils 37 ist das Loch 25 zu sehen, an dem beispielsweise mit Hilfe eines Schäkels die Zugfedern 26 angreifen.Fig. 4 shows an enlarged and perspective view of the lower end 23 of the rod 21. At the lower end, the neck 24 is welded, for example a flat iron. The approach 24 engages through the slot 36 of the hollow profile 37 of the side rail 11 of the goal frame. The hole 25 can be seen within the hollow profile 37, on which the tension springs 26 engage, for example with the aid of a shackle.

Auf der Außenseite des Hohlprofils 37 weist der Ansatz 24 zwei Rollen 38 auf, von denen in Fig. 4 nur eine zu sehen ist. Die gegenüberliegende, auf der Rückseite des Ansatzes 24 vorhandene Rolle 38 ist nicht zu sehen, sie liegt jedoch an der gegenüberliegenden Längsseite des Schlitzes 36. Bei der Aufwärtsbewegung des unteren Endes 23 der Stange 21 ver­kippt sich der Ansatz 24 um eine horizontale Achse, was durch die einseitige Anordnung der Rollen 38 ermöglicht wird.On the outside of the hollow profile 37, the projection 24 has two rollers 38, of which only one can be seen in FIG. 4. The opposite roller 38 present on the rear side of the projection 24 cannot be seen, but it lies on the opposite longitudinal side of the slot 36. During the upward movement of the lower end 23 of the rod 21, the projection 24 tilts about a horizontal axis, which is caused by the one-sided arrangement of the rollers 38 is made possible.

Die Länge des Schlitzes 36 ist so bemessen, daß das Tor vollständig geöffnet werden kann. Sie hängt im wesentlichen neben den absoluten Abmessungen von dem Abstand zwischen der Gelenkachse 16 und dem Bolzen 22 ab.The length of the slot 36 is dimensioned so that the gate can be opened completely. In addition to the absolute dimensions, it essentially depends on the distance between the hinge axis 16 and the bolt 22.
