Abstract

A folding gate comprises two rectangular segments connected for articulation by hinges, said first segment being supported directly by a gate wing bearing. Said second segment includes a panel and a carrier structure to support the weight of the panel, said carrier structure comprises a pivot arm which is disposed at the upper edge of the second segment and from which the panel is suspended, wherein the pivot arm is connected by its one end to a carrier structure of the first segment in articulated fashion such that the pivot arm is movable not only about a vertical axis but to a limited extent also about a horizontal axis with respect to the first segment, and wherein the other end of the pivot arm is guided horizontally and supported vertically at a glide track arrangement by means of a guide roller. By this structure any impact hitting the panel of the second segment practically is not transmitted to the first segment. The weight of the second segment is carried approximately evenly by the glide track arrangement and by the first segment.

Description

Die Erfindung bezieht sich auf ein Falttor gemäss dem Oberbegriff von Anspruch 1.The invention relates to a folding door according to the preamble of claim 1.

Ein solches Falttor ist bekannt (z. B. DE-A Nr. 2829912). Es findet insbesondere bei Fabrik-und Lagerhallen Anwendung und hat den Vorteil, dass mit seiner Hilfe verhältnissmässig breite Tor- öffnungen geschlossen werden können, wobei der zum Öffnen der Torflügel, von denen in der Regel zwei vorgesehen sind, benötigte Raum sowie der für die geöffneten Torflügel benötigte Raum verhältnismässig gering ist. Beim Öffnen wird jeder Torflügel gefaltet, so dass seine Segmente aneinander anliegen. Das Öffnen erfolgt üblicherweise mit Hilfe einer Öffnungsvorrichtung, die die Torflügel maschinell öffnet und beispielsweise von einer Lichtschranke gesteuert wird, die anspricht, wenn sich ein Fahrzeug dem Falttor nähert.Such a folding door is known (e.g. DE-A No. 2829912). It is used in particular in factories and warehouses and has the advantage that it can be used to close relatively wide door openings, the space required to open the door leaves, two of which are generally provided, and the space required for the open ones Gate wing space is relatively small. When the gate is opened, it is folded so that its segments lie against each other. The opening is usually carried out with the aid of an opening device which mechanically opens the door leaves and is controlled, for example, by a light barrier which responds when a vehicle approaches the folding door.

Bei dem bekannten Falttor sind die Tragkonstruktionendereinzelnen Segmente als steife Rahmen ausgebildet, die auch Abschnitte entlang den einander zugewandten Rändern der beiden Segmente haben. Zwischen diesen Abschnitten der Tragkonstruktionen befinden sich mehrere über die Höhe des Falttors verteilte Scharniere, die für die gelenkige Verbindung zwischen dem ersten Segment und dem zweiten Segment sorgen und ausserdem das gesamte Gewicht des zweiten Segmentes tragen und in die Tragkonstruktion des ersten Segmentes einleiten. Die in der Laufschienenanordnung laufende Leitrolle stützt sich lediglich in einer horizontalen Ebene an der Laufschienenanordnung ab und sorgt dafür, dass das vom ersten Segment abgewandte Ende des oberen Randes des zweiten Segmentes beim Öffnen und Schliessen der gewünschten, durch die Laufschienenanordnung bestimmten Bahn folgt.In the known folding door, the supporting structures of the individual segments are designed as rigid frames, which also have sections along the mutually facing edges of the two segments. Between these sections of the supporting structures there are several hinges distributed over the height of the folding door, which provide the articulated connection between the first segment and the second segment and also bear the entire weight of the second segment and lead into the supporting structure of the first segment. The guide roller running in the running rail arrangement is supported only in a horizontal plane on the running rail arrangement and ensures that the end of the upper edge of the second segment facing away from the first segment follows the desired path determined by the running rail arrangement when opening and closing.

Im Betrieb kann es bisweilen vorkommen, dass kräftig gegen eines oder mehrere Segmente der Torflügel gestossen wird, beispielsweise wenn die Öffnungsvorrichtung das Falttor nicht schnell genug öffnet und ein Transportfahrzeug gegen das noch nicht vollständig geöffnete Falttor fährt. In einem solchen Fall wird häufig nicht nur die getroffene Segmentfüllung, sondern auch die Tragkonstruktion des betreffenden Segmentes beschädigt. Ausserdem wird häufig selbst dann auch das erste Segment beschädigt, wenn der Stoss unmittelbar nur auf das zweite Segmente erfolgt ist. Diese Beschädigungen verursachen einen erheblichen Reparaturaufwand.During operation, it can sometimes happen that one or more segments of the gate wing are pushed hard, for example if the opening device does not open the folding door quickly enough and a transport vehicle drives against the folding door which has not yet been fully opened. In such a case, not only is the segment filling hit, but also the supporting structure of the segment in question is damaged. In addition, the first segment is often damaged even if the impact was only immediately on the second segment. This damage causes a considerable amount of repair work.

Der Erfindung liegt die Aufgabe zugrunde, das gattungsgemässe Falttor derart auszubilden, dass der Reparaturaufwand im Falle von Stössen gegen das Falttor verringert ist.The invention has for its object to design the generic folding door in such a way that the repair effort in the event of bumps against the folding door is reduced.

Diese Aufgabe wird erfindungsgemäss durch die Merkmale im kennzeichnenden Teil von Anspruch 1 gelöst.According to the invention, this object is achieved by the features in the characterizing part of claim 1.

Bei dem erfindungsgemässen Falttor ist die Segmentfüllung des zweiten Segments am Schwenkarm aufgehängt, der sich am oberen Rand des zweiten Segments befindet, wobei die Tragkonstruktion des zweiten Segments vorzugsweise ausschliesslich aus dem Schwenkarm besteht. Aufgrund der erfindungsgemässen Ausbildung kann eine tragende Verbindung zwischen den beiden Segmenten an ihren einander zugewandten Rändern und im wesentlichen über deren gesamte Höhe entfallen, so dass Stösse gegen die Segmentfüllung des zweiten Segmentes praktisch nicht zum ersten Segment übertragen werden und demzufolge dieses auch nicht beschädigen können. Die erfindungsgemässe Ausbildung sorgtferner dafür, dass das Gewicht des zweiten Segmentes in etwa zu gleichen Teilen von der Laufschienenanordnung und vom ersten Segment getragen wird. Im Vergleich zum bekannten Falttor, bei dem das erste Segment bzw. dessen Tragkonstruktion das gesamte Gewicht des zweiten Segmentes zu tragen hat, ist somit die Belastung des ersten Segmentes durch das zweite Segment beim erfindungsgemässen Falttor verringert. Damit nicht aufgrund ungünstiger Toleranz oder aufgrund von Richtfehlern trotz der Abstützung des Schwenkarms an seinem anderen Ende an der Laufschienenanordnung das gesamte Gewicht des zweiten Segmentes an der Gelenkverbindung zwischen dem Schwenkarm und der Tragkonstruktion des ersten Segmentes in diese eingeleitet wird, ist beim erfindungsgemässen Falttor vorgesehen, dass der Schwenkarm ausser um eine vertikale Achse auch begrenzt um eine horizontale Achse relativ zum ersten Segment bewegbar ist, so dass der Schwenkarm frei zwischen den beiden Abstützungen an seinen beiden Enden hängen kann und eine statische Überbestimmung vermieden ist, die eine stärkere Dimensionierung der Tragkonstruktion des ersten Segmentes erfordern würde.In the folding door according to the invention, the segment filling of the second segment is suspended from the swivel arm, which is located at the upper edge of the second segment, the support structure of the second segment preferably consisting exclusively of the swivel arm. Due to the design according to the invention, a load-bearing connection between the two segments on their mutually facing edges and essentially over their entire height can be dispensed with, so that impacts against the segment filling of the second segment are practically not transmitted to the first segment and consequently cannot damage it. The design according to the invention also ensures that the weight of the second segment is borne in approximately equal parts by the running rail arrangement and by the first segment. In comparison to the known folding door, in which the first segment or its supporting structure has to bear the entire weight of the second segment, the load on the first segment by the second segment is reduced in the folding door according to the invention. So that the entire weight of the second segment at the articulated connection between the swivel arm and the supporting structure of the first segment is not introduced into it due to unfavorable tolerance or due to alignment errors despite the support of the swivel arm at its other end on the running track arrangement, the inventive folding door provides that the swivel arm can be moved around a horizontal axis relative to the first segment in addition to a vertical axis, so that the swivel arm can hang freely between the two supports at its two ends and a static overdetermination is avoided, which means that the supporting structure of the structure is more dimensioned first segment would require.

Die Tatsache, dass beim erfindungsgemässen Falttor die Segmentfüllung des zweiten Segmentes am Schwenkarm aufgehängt ist, schliesst nicht aus, dass die Segmentfüllung des zweiten Segmentes mit dem ersten Segment unmittelbar verbunden ist, sofern es sich bei der letztgenannten Verbindung nicht um eine zur Übertragung stärkerer vertikaler und/oder horizontaler Kräfte geeignete Verbindung handelt, sondern beispielsweise lediglich um nachgiebige Dichtleisten oder Manschetten, die den Spalt zwischen den beiden Segmenten abdichten sollen.The fact that in the folding door according to the invention the segment filling of the second segment is suspended on the swivel arm does not exclude that the segment filling of the second segment is directly connected to the first segment, provided that the latter connection is not a vertical and / or horizontal forces suitable connection, but, for example, only about flexible sealing strips or sleeves, which are intended to seal the gap between the two segments.

In vorteilhafter Ausbildung der Erfindung kann vorgesehen sein, dass die Tragkonstruktion des ersten Segments einen Steifen, L-förmigen Rahmen umfasst, dessen einer Schenkel vertikal auf der oder parallel zur Achse des Torflügellagers verläuft und dessen anderer Schenkel waagerecht entlang dem oberen Rand des ersten Segmentes verläuft und an seinem freien Ende die gelenkige Verbindung mit dem einen Ende des Schwenkarms aufweist.In an advantageous embodiment of the invention, it can be provided that the supporting structure of the first segment comprises a rigid, L-shaped frame, one leg of which runs vertically on or parallel to the axis of the gate wing bearing and the other leg of which runs horizontally along the upper edge of the first segment and has at its free end the articulated connection with one end of the swivel arm.

Bei dieser Ausbildung sind die Tragkonstruktionen des Torflügels ausschliesslich entlang den Rändern der Toröffnung und somit in einem Bereich angeordnet, in dem die Gefahr, dass sie direkt getroffen werden, am geringsten ist, und zudem die Entfernung vom am häufigsten getroffenen Bereich des Falttores, der sich unten nahe dem freien Rand des zweiten Segmentes befindet, am grössten ist. Gerade in Verbindung mit diesem L-förmigen Rahmen als Tragkonstruktion des ersten Segmentes ist die Einleitung ungefähr des halben Gewichts des zweiten Segmentes in die Laufschienenanordnung und somit die teilweise Entlastung des ersten Segmentes vom Gewicht des zweiten Segmentes von besonderem Vorteil, weil dadurch der horizontale Schenkel entsprechend schwächer ausgebildet sein kann.With this design, the supporting structures of the gate wing are arranged exclusively along the edges of the gate opening and thus in an area where the risk of being hit directly is the lowest, and also the distance from the most frequently hit area of the folding door, which is located near the free edge of the second segment at the bottom is largest. Especially in connection with this L-shaped frame as the supporting structure of the first segment, the introduction of approximately half the weight of the second segment into the running track arrangement and thus the partial relief of the weight of the second segment from the first segment is particularly advantageous because the horizontal leg accordingly can be weaker.

In weiterer vorteilhafter Ausbildung der Erfindung kann vorgesehen sein, dass die Segmentfüllungen Bahnen aus einem flexiblen Werkstoff sind. Hierfür kommt insbesondere Weich-PVC oder Gummi in Frage. Die Segmentfüllungen können aber auch aus zwei übereinander angeordneten, steifen Platten bestehen, wobei die untere Platte jeweils an der oberen Platte aufgehängt ist. Auch in diesem Fall bleibt das Prinzip gewahrt, dass zumindest beim zweiten Segment die Segmentfüllung vom Schwenkarm getragen wird und keine tragende Verbindung zwischen den beiden einander zugewandten Rändern des ersten und zweiten Segments besteht, wobei jedoch zugleich wegen der steifen Ausbildung der Platten die Möglichkeit besteht, das Falttor als verschliessbares Aussentor einzusetzen. Die Ausbildung der Segmentfüllungen in Form einzelner steifer Platten, die lediglich aufgehängt sind und nicht in einen sie allseits umschliessenden steifen Rahmen eingesetztsind, bringt den Vorteil mitsich, dass bei den üblichen Beschädigungen lediglich eine einzelne Platte ausgetauscht zu werden braucht, die übrigen Platten und die Tragkonstruktionen jedoch unbeschädigt sind und nicht repariert zu werden brauchen.In a further advantageous embodiment of the invention, it can be provided that the segment fillings are webs made of a flexible material. Soft PVC or rubber are particularly suitable for this. The segment fillings can also consist of two rigid plates arranged one above the other, the lower plate being suspended from the upper plate in each case. In this case too, the principle is maintained that, at least in the second segment, the segment filling is carried by the swivel arm and there is no load-bearing connection between the two mutually facing edges of the first and second segments, but at the same time there is the possibility due to the rigid construction of the plates, use the folding door as a lockable outer door. The design of the segment fillings in the form of individual rigid plates, which are only suspended and are not inserted into a rigid frame surrounding them on all sides, has the advantage that, with the usual damage, only a single plate needs to be replaced, the remaining plates and the supporting structures however, are undamaged and do not need to be repaired.

Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen gekennzeichnet.Further advantageous embodiments of the invention are characterized in the subclaims.

Im folgenden wird zunächst das Falttor gemäss den Fig. 1, 2 und 3 beschrieben. Das dargestellte Falttor befindet sich in oder vor einer nicht dargestellten Toröffnung, entlang deren oberer Begrenzung eine Laufschienenanordnung 2 befestigt ist, die im wesentlichen aus zwei zueinander parallelen, geraden, horizontal verlaufenden Laufschienen 4 und 6 besteht, wie dies Fig. 3 zeigt. Am in Fig.1 linken Rand der Toröffnung befindet sich ein Torflügellager, das aus einem unteren Zapfenlager 8 und einem oberen Zapfenlager 10 besteht, die gemeinsam eine vertikale Achse 12 definieren, um die ein insgesamt mit 14 bezeichneterTorflügel geschwenkt werden kann, der im dargestellten, geschlossenen Zustand die Hälfte der Toröffnung schliesst.The folding gate according to FIGS. 1, 2 and 3 is first described below. The folding door shown is located in or in front of a door opening, not shown, along whose upper boundary a running rail arrangement 2 is fastened, which essentially consists of two parallel, straight, horizontally running running rails 4 and 6, as shown in FIG. 3. At the left edge of the gate opening in FIG. 1 there is a gate wing bearing, which consists of a lower pivot bearing 8 and an upper pivot bearing 10, which together define a vertical axis 12, about which a gate wing, generally designated 14, can be pivoted, which closed state closes half of the door opening.

Der Torflügel 14 besteht aus einem ersten, in Fig. 1 linken Segment 16 sowie einem zweiten, in Fig. 1 rechten Segment 18. Die beiden Segmente 16 und 18 haben einen im wesentlichen rechteckigen Umriss. Das erste Segment 16 weist eine Segmentfüllung 20 in Form einer Bahn aus einem elastischen, flexiblen Werkstoff, beispielsweise aus Weich-PVC, auf, die sich praktisch über die gesamte Höhe und die gesamte Breite des ersten Segmentes 16 erstreckt. Ferner umfasst das erste Segment 16 eine Tragkonstruktion in Form eines L-förmig Rahmens 22, der aus einem vertikalen Schenkel 24 und einem am oberen Ende mit dem vertikalen Schenkel 24 fest verbundenen horizontalen Schenkel 26 besteht, der in Fig. 1 nach rechts vom vertikalen Schenkel 24 ausgeht. Der vertikale Schenkel 24 ist an seinen beiden Enden in den Lagern 8 und 10 drehbar gelagert. Auf den Innenseiten der beiden Schenkel 24 und 26 ist beispielsweise durch Schweissen jeweils eine Leiste 28 bzw. 30 befestigt. Die beiden Leisten 28 und 30 dienen dazu, an ihnen die Segmentfüllung 20 beispielsweise mit Hilfe einiger nicht dargestellter Schrauben am in Fig. 1 linken und oberen Rand der Segmentfüllung 20 zu befestigen.The gate wing 14 consists of a first segment 16 on the left in FIG. 1 and a second segment 18 on the right in FIG. 1. The two segments 16 and 18 have an essentially rectangular outline. The first segment 16 has a segment filling 20 in the form of a web made of an elastic, flexible material, for example made of soft PVC, which extends practically over the entire height and the entire width of the first segment 16. Furthermore, the first segment 16 comprises a supporting structure in the form of an L-shaped frame 22, which consists of a vertical leg 24 and a horizontal leg 26 which is fixedly connected to the vertical leg 24 at the upper end and which is to the right in FIG. 1 from the vertical leg 24 goes out. The vertical leg 24 is rotatably supported at its two ends in the bearings 8 and 10. On the inner sides of the two legs 24 and 26, for example, a strip 28 or 30 is attached, for example by welding. The two strips 28 and 30 serve to fasten the segment filling 20 to them, for example with the aid of a few screws, not shown, on the left and upper edge of the segment filling 20 in FIG. 1.

Es ist erkennbar, dass die Tragkonstruktion des ersten Segmentes 16, die aus dem Rahmen 22 besteht, sich ausschliesslich entlang dem in Fig. 1 linken und oberen Rand des Segmentes 16 erstreckt und keine Elemente am unteren und rechten Rand des Segmentes 16 hat. Die Tragkonstruktion des ersten Segmentes 16 verläuft somit ausschliesslich entlang dem Rand der nicht dargestellten Toröffnung, d. h. in einem Bereich, auf den im Betrieb praktisch keine unmittelbaren Stösse ausgeübt werden.It can be seen that the supporting structure of the first segment 16, which consists of the frame 22, extends exclusively along the left and upper edge of the segment 16 in FIG. 1 and has no elements on the lower and right edge of the segment 16. The support structure of the first segment 16 thus runs exclusively along the edge of the gate opening, not shown, i. H. in an area to which practically no direct impacts are exerted.

Am in Fig. 1 rechten Ende des horizontalen Schenkels 26 befindet sich ein Zapfen 32, an dem eine Öffnungsvorrichtung für das Falttor angreift, von der in Fig. 1 lediglich ein pneumatischer Zylinder 34 dargestellt ist, der je nach Beaufschlagung das erste Segment 16 entweder in die dargestellte Schliessstellung schwenkt oder aus dieser heraus in eine nicht dargestellte Offenstellung bringt. Auf die genaue Ausbildung der Öffnungsvorrichtung kommt es jedoch zum Verständnis der Erfindung nicht an.At the right end of the horizontal leg 26 in FIG. 1 there is a pin 32 on which an opening device for the folding door engages, of which only a pneumatic cylinder 34 is shown in FIG. 1, which, depending on the loading, the first segment 16 either in the closed position shown pivots or brings it out of this into an open position, not shown. The precise design of the opening device is not important for understanding the invention.

Das zweite Segment 18 des Torflügels 14 umfasst eine Segmentfüllung 36, die so wie die Segmentfüllung 20 aus einer Bahn, aus einem flexiblen, elastischen Werkstoff besteht und die sich praktisch über die gesamte Höhe und Breite des zweiten Segmentes 18 erstreckt. Dabei ist erkennbar, dass sich die Segmentfüllungen 20 und 36 im Bereich ihrer einander zugewandten Ränder überlappen und dass der in Fig. 1 rechte Rand 30 der Segmentfüllung 36 derart verläuft, dass dort eine Überlappung mit der entsprechenden Segmentfüllung 40 des ansonsten nicht dargestellten rechten Torflügels vorliegt, wenn das Falttor geschlossen ist.The second segment 18 of the gate wing 14 comprises a segment filling 36 which, like the segment filling 20, consists of a sheet made of a flexible, elastic material and which extends practically over the entire height and width of the second segment 18. It can be seen that the segment panels 20 and 36 overlap in the region of their mutually facing edges and that the right edge 30 of the segment panel 36 in FIG. 1 extends such that there is an overlap with the corresponding segment panel 40 of the otherwise not shown right gate wing when the folding door is closed.

Das zweite Segment 18 umfasst ausser der Segmentfüllung 36 als Tragkonstruktion einen steifen, im wesentlichen geraden Schwenkarm 42, der beispielsweise aus einem Profilrohr hergestellt sein kann. Der Schwenkarm 42 verläuft entlang dem oberen Rand des zweiten Segmentes 18 und somit der Segmentfüllung 36, die am Schwenkarm 42 mit Hilfe einer Leiste 44 befestigt ist, die am übrigen Schwenkarm 42 angeschweisst ist. Die Verbindung zwischen der Leiste 44 und der Segmentfüllung 36 bewirken einige nicht dargestellte Schrauben. Das gesamte Gewicht der Segmentfüllung 36 wird vom Schwenkarm 42, an dem die Segmentfüllung 36 ausschliesslich aufgehängt ist, getragen, so dass zum Tragen der Segmentfüllung 36 keine weiteren Tragkonstruktionsabschnitte entlang den beiden seitlichen Rändern oder entlang dem unteren Rand des Segmentes 18 notwendig sind. Aufgrund der beschriebenen Ausbildung der Segmentfüllung 36 und des Schwenkarmes 42 sowie der beschriebenen Verbindung zwischen dem Schwenkarm und der Segmentfüllung ist die Segmentfüllung am Schwenkarm 42 gelenkig aufgehängt, denn die Elastizität und Flexibilität des Werkstoffs, aus dem die Segmentfüllung 36 besteht, erlaubt es, die Segmentfüllung nach vorne oder hinten zu schwenken, wobei ihr nahe der Leiste 44 befindlicher Bereich etwas umgebogen wird, ohne dass nennenswerte Kräfte in den Schwenkarm 42 eingeleitet werden.In addition to the segment filling 36 as the supporting structure, the second segment 18 comprises a rigid, essentially straight swivel arm 42, which can be made for example from a profile tube. The swivel arm 42 runs along the upper edge of the second segment 18 and thus the segment filling 36, which is fastened to the swivel arm 42 with the aid of a strip 44 which is welded to the rest of the swivel arm 42. The connection between the strip 44 and the segment filling 36 effect some screws, not shown. The entire weight of the segment filling 36 is borne by the swivel arm 42, on which the segment filling 36 is only suspended, so that no further supporting construction sections along the two lateral edges or along the lower edge of the segment 18 are necessary for carrying the segment filling 36. Due to the described design of the segment filling 36 and the swivel arm 42 and the described connection between the swivel arm and the segment filling, the segment filling is articulated on the swivel arm 42, because the elasticity and flexibility of the material from which the segment filling 36 is made allows the segment filling to pivot forward or backward, its area near the bar 44 being slightly bent without any significant forces being introduced into the pivot arm 42.

Der Schwenkarm 42 ist an seinem in Fig. 1 linken Ende gelenkig mit dem freien Ende des horizontalen Schenkels 26 verbunden. Die Ausbildung dieser Gelenkverbindung zeigt ausführlich Fig. 2. Zwischen dem Schenkel 26 und dem Schwenkarm 42 ist ein Zwischenstück 46 angeordnet, in dem zwei Lagerbohrungen 48 und 50 ausgebildet sind. In die Lagerbohrung 48 ist ein Lagerstift 52 eingesetzt, dessen Achse in vertikaler Richtung verläuft und die Schwenkachse zwischen dem ersten Segment 16 und dem zweiten Segment 18 definiert. Der Lagerstift 52 ist an seinem oberen und an seinem unteren Ende in Laschen 54 befestigt, von denen in Fig. 2 lediglich die untere Lasche 54 erkennbar ist und die ihrerseits am freien Ende des Schenkels 26 befestigt sind. Diese Ausbildung ermöglicht es, das Zwischenstück 46 in einer horizontalen Ebene um den Lagerstift 52 und somit relativ zum Schenkel 26 zu verschwenken. Die andere Lagerbohrung 50 hat eine waagerechte Achse, die in gewissem Abstand zur Achse der Lagerbohrung 48 verläuft. In die Lagerbohrung 50 ist ein Lagerstift 56 eingesetzt, der mit seinen beiden Enden am in den Fig. 1 und 2 linken Ende des Schwenkarms 42 befestigt ist, so dass der Schwenkarm 42 relativ zum Zwischenstück 46 in einer senkrechten Ebene verschwenkt werden kann. Die vorstehend beschriebene Gelenkverbindung ist somit derart, dass der Schwenkarm 42 relativ zum Schenkel 26 und somit zum Rahmen 22 ausser um eine vertikale Achse, nämlich die Achse des Lagerstiftes 52, auch um eine horizontale Achse, nämlich die Achse des Lagerstiftes 56 bewegbar ist.The swivel arm 42 is articulated at its left end in FIG. 1 to the free end of the horizontal leg 26. The design of this articulated connection is shown in detail in FIG. 2. Between the leg 26 and the swivel arm 42 there is an intermediate piece 46 in which two bearing bores 48 and 50 are formed. A bearing pin 52 is inserted into the bearing bore 48, the axis of which extends in the vertical direction and defines the pivot axis between the first segment 16 and the second segment 18. The bearing pin 52 is fastened at its upper and at its lower end in tabs 54, of which only the lower tab 54 can be seen in FIG. 2 and which in turn are attached to the free end of the leg 26. This design makes it possible to pivot the intermediate piece 46 in a horizontal plane around the bearing pin 52 and thus relative to the leg 26. The other bearing bore 50 has a horizontal axis which runs at a certain distance from the axis of the bearing bore 48. In the bearing bore 50, a bearing pin 56 is inserted, which is fastened with its two ends to the left end of the pivot arm 42 in FIGS. 1 and 2, so that the pivot arm 42 can be pivoted in a vertical plane relative to the intermediate piece 46. The articulated connection described above is thus such that the swivel arm 42 can be moved relative to the leg 26 and thus to the frame 22 in addition to a vertical axis, namely the axis of the bearing pin 52, and also about a horizontal axis, namely the axis of the bearing pin 56.

Am in Fig. 1 rechten Ende ist der Schwenkarm 42 an einem Laufwagen 58 aufgehängt, wie dies ausführlicher in Fig. 3 gezeigt ist. Vom rechten Ende des Schwenkarms 42 geht ein in Fig. 1 senkrecht zur Zeichenebene verlaufender kurzer Querarm 60 aus, an dessen freiem Ende ein vertikal verlaufender Stab 62 befestigt ist. Auf dem Stab 62 ist drehbar in Höhe der beiden Laufschienen 4 und 6 eine Leitrolle 64 gelagert, die von den beiden Laufschienen 4 und 6 in einer horizontalen Ebene geführt wird, so dass die Leitrolle 64 lediglich der durch die Laufschienenanordnung 2 definierten geraden Bahn folgen kann. Dadurch ist zugleich auch die Bewegungsbahn des in Fig. 1 rechten Randes des zweiten Segmentes 18 beim Öffnen und Schliessen des Falttoresfestgelegt. An seinem oberen Ende ist der Stab 62 mittels eines nicht ausführlich gezeigten, geeigneten Gelenkes derart gelenkig am Laufwagen 58 aufgehängt, dass der Stab 62 innerhalb eines gewissen Bereichs nach allen Seiten bezüglich des Laufwagens 58 geschwenkt werden kann. Die Verbindung zwischen dem Stab 62 und dem Laufwagen 58 ist allerdings derart, dass sie vertikale Kräfte vom Querarm 60 und somit vom Schwenkarm 42 in den Laufwagen 58 einleiten kann, der diese wiederum mit Hilfe von Laufrollen 66, die auf den Oberseiten der Laufschienen 4 und 6 laufen können, in die Laufschienen und somit in die Laufschienenanordnung 2 einleitet.At the right end in FIG. 1, the swivel arm 42 is suspended from a carriage 58, as is shown in more detail in FIG. 3. From the right end of the swivel arm 42 a short transverse arm 60 extends perpendicular to the plane of the drawing in FIG. 1 and a vertically extending rod 62 is fastened to the free end thereof. On the rod 62, a guide roller 64 is rotatably mounted at the level of the two guide rails 4 and 6, which is guided by the two guide rails 4 and 6 in a horizontal plane, so that the guide roller 64 can only follow the straight path defined by the guide rail arrangement 2 . This also defines the path of movement of the right edge of the second segment 18 in FIG. 1 when the folding door is opened and closed. At its upper end, the rod 62 is articulated on the carriage 58 by means of a suitable joint (not shown in detail) in such a way that the rod 62 can be pivoted in all directions with respect to the carriage 58 within a certain range. The connection between the rod 62 and the carriage 58 is, however, such that it can introduce vertical forces from the transverse arm 60 and thus from the swivel arm 42 into the carriage 58, which in turn by means of rollers 66, which are on the upper sides of the rails 4 and 6 can run, introduces into the running rails and thus into the running rail arrangement 2.

Auf die vorstehend beschriebene Weise ist somit der Schwenkarm 42 an seinen beiden Enden aufgehängt, nämlich einerseits mit Hilfe des Laufwagens 58 an der Laufschienenanordnung 2 und andererseits mit Hilfe des Zwischenstücks 46 am Rahmen 22. Aufgrund der Tatsache, dass der Schwenkarm 42 am Rahmen 22 auch in einer vertikalen Ebene verschwenkbar ist, was beim dargestellten Ausführungsbeispiel durch das Stiftlager mit dem Lagerstift 56 und der Lagerbohrung 50 ermöglicht ist, nimmt der Schwenkarm 42 eine solche Lage ein, dass das Gewicht des zweiten Segmentes 18 entsprechend der Geometrie des zweiten Segmentes 18 gleichmässig auf die beiden Abstützungen des Schwenkarm 42 verteilt ist, so dass der Rahmen 22 lediglich so dimensioniert zu werden braucht, dass er den auf ihn entfallenden Gewichtsanteil des zweiten Segmentes 18 tragen kann.In the manner described above, the swivel arm 42 is thus suspended at both ends, namely on the one hand with the help of the carriage 58 on the running rail arrangement 2 and on the other hand with the aid of the intermediate piece 46 on the frame 22. Due to the fact that the swivel arm 42 on the frame 22 also is pivotable in a vertical plane, which is made possible in the illustrated embodiment by the pin bearing with the bearing pin 56 and the bearing bore 50, the swivel arm 42 assumes a position such that the weight of the second segment 18 is evenly corresponding to the geometry of the second segment 18 the two supports of the swivel arm 42 are distributed, so that the frame 22 only has to be dimensioned such that it can carry the weight portion of the second segment 18 which is attributable to it.

Aus der vorstehenden Beschreibung ergibt sich, dass bei dem erläuterten Torflügel 14 die Tragkonstruktionen der beiden Segmente 16 und 18 ausschliesslich im Bereich der Ränder der Toröffnung bzw. der Ränder des Torflügels angeordnet sind und somit ausserhalb desjenigen Bereichs, in dem die grösste Beschädigungsgefahr besteht. Zudem sind die beiden Segmente 16 und 18 nicht entlang ihren einander zugewandten Rändern tragend miteinander verbunden, so dass in diesem Bereich keine stärkeren Kräfte von einem Segment zum anderen übertragen werden können. Dem steht nicht entgegen, dass beispielsweise am unteren Rand des Torflügels 14 die beiden Segmentfüllungen 20 und 36 beispielsweise mittels einer elastischen Lasche 68 miteinander verbunden sind, die verhindern soll, dass die beiden Segmentfüllungen 20 und 26 sich falsch überlappen, die jedoch stärkeren Stossbeanspruchungen nicht standhalten würde.It follows from the above description that in the case of the gate leaf 14 explained, the supporting structures of the two segments 16 and 18 are arranged exclusively in the region of the edges of the gate opening or the edges of the gate leaf and thus outside the region in which there is the greatest risk of damage. In addition, the two segments 16 and 18 are not connected to one another in a load-bearing manner along their mutually facing edges, so that no greater forces can be transmitted from one segment to the other in this region. This does not conflict with the fact that, for example, at the lower edge of the gate wing 14, the two segment fillings 20 and 36 are connected to one another, for example by means of an elastic tab 68, which is intended to prevent the two segment fillings 20 and 26 from overlapping incorrectly, but which is stronger would not withstand their shock loads.

Das Ausführungsbeispiel gemäss Fig. 4 stimmt weitgehend mit dem vorstehend anhand der Fig. 1 bis 3 beschriebenen Ausführungsbeispiel überein und unterscheidet sich von diesem lediglich hinsichtlich der Ausbildung der Segmentfüllungen, weswegen eine erneute Beschreibung der übrigen Elemente nicht erfolgt. Bei dem Ausführungsbeispiel gemäss Fig. 4 besteht die Segmentfüllung 36 des zweiten Segmentes 18 aus zwei steifen, rechtwinkligen Platten 74 und 76, die übereinander angeordnet sind, wobei die untere Platte 76 an der oberen Platte 74 aufgehängt ist, die wiederum an der Leiste 44 aufgehängt ist. Die jeweiligen Aufhängungen sind nicht steif, so dass beispielsweise die untere Platte 76 relativ zur oberen Platte 74 verschwenkt werden kann, ohne dass zugleich die obere Platte 74 mitbewegt wird.The embodiment according to FIG. 4 largely corresponds to the embodiment described above with reference to FIGS. 1 to 3 and differs from it only with regard to the design of the segment fillings, for which reason the other elements are not described again. 4, the segment filling 36 of the second segment 18 consists of two rigid, rectangular plates 74 and 76, which are arranged one above the other, the lower plate 76 being suspended from the upper plate 74, which in turn is suspended from the bar 44 is. The respective suspensions are not stiff, so that, for example, the lower plate 76 can be pivoted relative to the upper plate 74 without the upper plate 74 also being moved.

Auf ähnliche Weise besteht die Segmentfüllung 20 des ersten Segmentes 16 aus zwei rechtwinkligen, steifen Platten 70 und 72, von denen die obere an den Leisten 30 und 22 befestigt ist, während die untere Platte 72 an der Leiste 28 befestigt ist und ausserdem an der oberen Platte 70 aufgehängt ist. Die Befestigungen der Platten 70 und 72 an den Leisten 30 und 28 sind vorzugsweise derart, dass im Falle von Stössen auf die Platten 70 und 72 die Befestigungsmittel brechen, bevor die Leisten 28 und 30 und der Rahmen 22 beschädigt werden.Similarly, the segment fill 20 of the first segment 16 consists of two rectangular rigid plates 70 and 72, the upper of which is attached to the strips 30 and 22, while the lower plate 72 is attached to the strip 28 and also the upper Plate 70 is hung. The fastenings of the plates 70 and 72 to the strips 30 and 28 are preferably such that in the event of impacts on the plates 70 and 72, the fastening means break before the strips 28 and 30 and the frame 22 are damaged.

Die steifen Platten 70, 72, 74 und 76 ermöglichen es, ein Falttor aus zwei Torflügeln der Art, wie sie in Fig. 4 dargestellt ist, als verschliessbares bzw. verriegelbares Aussentor zu verwenden. Zugleich ist es jedoch möglich, im Falle von Beschädigungen des Torflügels die jeweils beschädigte Platte auszutauschen, ohne dass zugleich das entsprechende Segment oder gar beide Segmente mit ihren Tragkonstruktionen ausgetauscht oder repariert zu werden brauchen.The rigid plates 70, 72, 74 and 76 make it possible to use a folding door made of two door leaves of the type shown in FIG. 4 as a closable or lockable outer door. At the same time, however, it is possible, in the event of damage to the gate wing, to replace the respectively damaged plate without the corresponding segment or even both segments with their supporting structures having to be exchanged or repaired at the same time.

Auch bei der Ausführungsform gemäss Fig. 4 gilt, dass die beiden Segmente 16 und 18 an ihren einander zugewandten Rändern nicht tragend miteinander verbunden sind. Dies schliesst jedoch nicht aus, dass sich dort nicht steife Verbindungselemente befinden, beispielsweise ein Abdeckelement 78 in Form eines elastischen Streifens, der den Spalt zwischen den beiden Segmentfüllungen 20 und 36 witterungsdicht schliesst.4 also applies that the two segments 16 and 18 are not connected to each other at their mutually facing edges. However, this does not rule out the fact that there are non-rigid connecting elements, for example a cover element 78 in the form of an elastic strip, which closes the gap between the two segment fillings 20 and 36 in a weatherproof manner.

Es versteht sich, dass sowohl bei der Ausführungsform gemäss Fig. 1 als auch bei der Ausführungsform gemäss Fig. 4 das Falttor jeweils durch einen nicht dargestellten zweiten Flügel vervollständigt ist. Allerdings sind auch Falttore mit lediglich einem aus miteinander verbundenen Segmenten bestehenden Torflügel möglich.It goes without saying that both in the embodiment according to FIG. 1 and in the embodiment according to FIG. 4, the folding door is in each case completed by a second wing (not shown). However, folding gates with only one gate wing consisting of interconnected segments are also possible.
