Abstract

The invention concerns a folding door with several pairs (2, 3) of panels and fitted with a simple, functional and space-saving device for opening out the individual pairs (2, 3) of panels. Fixed to the neighbouring panels (2a, 3a) of two pairs (2, 3) of panels are entrainment pieces (7) in whose field of traverse lie the arms (8a) of two-armed levers (8). The other arms (8b) of the levers (8) extend to the nearest respective panel (2a) and (3a) so that, when one of the panels (e.g. 2a) pivots, from a certain point in the pivoting motion a turning moment is generated which acts via the entrainment piece (7), the lever arm (8a) and the lever arm (8b) on the neighbouring panel (3a) in the opening direction.

Description

Die vorliegende Erfindung betrifft eine Falttür mit mehreren Flügelpaaren, wobei die Flügel jedes Flügelpaares gelenkig miteinander verbunden und jeweils zwei benachbarte Flügelpaare an einer gemeinsamen Trageinrichtung anscharniert sind und zumindest die Trageinrichtung bzw. die Trageinrichtungen mindestens längs einer horizontalen Führungsschiene geführt ist bzw. sind und daß jeweils an mindestens einem im Scharnierbereich liegenden Flügel ein Mitnehmer angeschlossen ist.The present invention relates to a folding door with a plurality of wing pairs, the wings of each wing pair being articulated to one another and each two adjacent wing pairs being hinged to a common support device and at least the support device or the support devices being guided at least along a horizontal guide rail and that and in each case a driver is connected to at least one wing located in the hinge area.

Eine Falttür der gattungsgemäßen Art ist aus der DE-A-1759226 bekanntA folding door of the generic type is known from DE-A-1759226

Bei Falttüren der gattungsgemäßen Art besteht das Problem, daß beim Öffnen der Flügelpaare aus der Schließlage heraus ein Drehmoment auf die einzelnen Flügel ausgeübt werden muß, welches die Flügel dazu veranlaßt, aus der Schließlage heraus um die Gelenkachse herum einzuknicken.In folding doors of the generic type, there is the problem that when the pairs of wings are opened, a torque must be exerted on the individual wings from the closed position, which causes the wings to buckle around the hinge axis from the closed position.

Beim Öffnungsvorgang kann auf das erste Flügelpaar, welches ein Benutzer zu öffnen gedenkt, meist über eine handhabe das erforderliche Drehmoment aufgebracht werden.During the opening process, the first pair of wings, which a user intends to open, can usually be manipulated the required torque can be applied.

Bei der Falttür gemäß der DE-A-17 59 226 sind die anschließenden Flügelpaare über je ein Getriebe miteinander gekuppelt, wobei die Getriebe eine synchrone Öffnungs- und Schließbewegung bewirken.In the folding door according to DE-A-17 59 226, the adjoining pairs of wings are coupled to one another via a gear mechanism, the gear mechanisms causing a synchronous opening and closing movement.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Falttür der gattungsgemäßen Art zu schaffen, bei der eine kostengünstig herstellbare und platzsparende Öffnungshilfe beim Öffnen aller Flügelpaare verwirklicht ist.The present invention has for its object to provide a folding door of the generic type, in which an inexpensive to manufacture and space-saving opening aid is realized when opening all pairs of wings.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß an der gemeinsamen Trageinrichtung ein um eine parallel zur Scharnierachse verlaufende Drehachse schwenkbarer, zweiarmiger Hebel angeschlossen ist, dessen einer Hebelarm im Schwenkbereich des Mitnehmers liegt und dessen anderer Hebelarm sich bis in den Bereich des Flügels erstreckt, der dem mit dem Mitnehmer ausgestatteten Flügel benachbart ist, so daß ab einem bestimmten Schwenkwinkel des mit dem .Mitnehmer ausgestatteten Flügels über den zweiarmigen Hebel ein in Öffnungsrichtung wirkendes Drehmoment auf den benachbarten Flügel ausgeübt wird.This object is achieved in that a two-armed lever is connected to the common support device which can be pivoted about an axis of rotation parallel to the hinge axis, one of which lever arm lies in the pivoting range of the driver and the other of which lever arm extends into the area of the wing which corresponds to the with the driver equipped wing is adjacent, so that from a certain pivoting angle of the wing equipped with the driver, a torque acting in the opening direction is exerted on the adjacent wing via the two-armed lever.

Eine derartige Konstruktion bietet eine hochwirksame Öffnungshilfe beim Auffalten der aufeinanderfolgenden Flügelpaare, ohne daß hierzu eine besondere Handhabungstechnik durch den Benutzer erforderlich ist. Darüber hinaus ist eine erfindungsgemäße Öffnungshilfe einfach aufgebaut, besteht aus nur wenigen Einzelteilen und, bedingt durch die Tatsache, daß der zweiarmige Hebel um eine parallel zur Scharnierachse verlaufende Drehachse schwenkbar ist, ist die erfindungsgemäße Öffnungshilfe auch äußerst platzsparend, was insbesondere bei Falttüren für Schränke von großer Bedeutung ist.Such a construction offers a highly effective opening aid when unfolding the successive pairs of wings without requiring a special handling technique by the user. In addition, an opening aid according to the invention is simply constructed, consists of only a few individual parts and, due to the fact that the two-armed lever about a parallel to the hinge axis extending axis of rotation is pivotable, the opening aid according to the invention is also extremely space-saving, which is of particular importance in the case of folding doors for cupboards.

Weitere Merkmale der Erfindung sind Gegenstand von Unteransprüchen.Further features of the invention are the subject of dependent claims.

Anhand der beigefügten Zeichnungen wird die vorliegende Erfindung im folgenden ausführlich beschrieben.The present invention will be described in detail below with reference to the accompanying drawings.

Es zeigen:

Show it:
  • 1 is a schematically illustrated rear view of a folding door with two pairs of wings,
  • 2 shows the detail designated II in FIG. 1 on an enlarged scale, partially shown in section,
  • 3 shows a section along the line III-III in FIG. 2,
  • 4 shows a section corresponding to FIG. 3 with a partial opening position of the wing pairs,

  • 6 shows a section along the line VI-VI in FIG. 5 with the folding door partially open,
  • 7 is a partial view in the direction of arrow VII in FIG. 5.

Die in Figur 1 dargestellte Falttür 1 weist zwei Flügelpaare 2 und 3 auf, wobei die Flügel 2a und 3a jedes Flügelpaares 2 und 3 gelenkig miteinander verbunden sind, was durch angedeutete Scharniere 4 verdeutlicht ist.The folding door 1 shown in Figure 1 has two pairs of wings 2 and 3, wherein the wings 2a and 3a of each pair of wings 2 and 3 are hinged together, which is illustrated by indicated hinges 4.

Die beiden benachbarten Flügelpaare 2 und 3 sind an einer gemeinsamen Trageinrichtung 5 anscharniert und diese Trageinrichtung 5 ist in bekannter Weise längs einer horizontal verlaufenden Führungsschiene 6 verschiebbar geführt.The two adjacent wing pairs 2 and 3 are hinged to a common support device 5 and this support device 5 is guided in a known manner along a horizontally extending guide rail 6.

Die in Figur 1 jeweils äußeren Flügel 2a und 3a sind darüber hinaus ebenfalls in der Führungsschiene 6 verschiebbar geführt.The outer wings 2a and 3a in FIG. 1 are also also displaceably guided in the guide rail 6.

Dies bedeutet, daß die Falttür 1 - bezogen auf die Darstellungsweise nach Figur 1 - sowohl nach links wie auch nach rechts geöffnet werden kannThis means that the folding door 1 - based on the representation according to Figure 1 - can be opened both to the left and to the right

Es sei an dieser Stelle schon darauf hingewiesen, daß der Grundgedanke der vorliegenden Erfindung nicht in ursächlichem Zusammenhang damit steht, ob die Falttür 1 nach beiden Seiten hin geöffnet werden kann oder ob jeweils einer der endseitigen Flügel 2a oder 3a bezüglich der Führungsschiene 1 festgelegt ist. Im letzteren Falle würde sich dann die Falttür 1 lediglich nach rechts oder nach links öffnen lassenAt this point it should be pointed out that the basic idea of the present invention is not causally related to whether the folding door 1 can be opened on both sides or whether one of the end wings 2a or 3a is fixed with respect to the guide rail 1. In the latter case, the folding door 1 would then only be able to be opened to the right or to the left

Das Problem, mit dem sich die vorliegenden Erfindung beschäftigt, ist darin zu sehen, daß beim Öffnen einer Falttür 1 auf die Flügel 2a und 3a der beiden Flügelpaare 2 und 3 ein Drehmoment ausgeübt werden muß, welches bewirkt, daß sich die Flügel 2a bzw. 3a aus ihrer Schließlage heraus unter Drehung um die Scharniere 4 einknicken.The problem with which the present invention is concerned is that when a folding door 1 is opened, a torque must be exerted on the wings 2a and 3a of the two wing pairs 2 and 3, which causes the wings 2a and 3a snap out of its closed position while rotating around the hinges 4.

Bei demjenigen Flügelpaar 2 oder 3, welches von einem Benutzer im Falle des Öffnens an einer nicht dargestellten Handhabe erfaßt wird, wird dieses entsprechende Drehmoment durch Ausübung einer entsprechenden Zug- oder Druckbewegung etwa lotrecht zum betreffenden Flügelpaar 2 oder 3 ausgeübt.In the case of the pair of wings 2 or 3 which is grasped by a user in the event of opening on a handle (not shown), this corresponding torque is exerted approximately perpendicular to the relevant pair of wings 2 or 3 by exercising a corresponding pulling or pushing movement.

Es geht nun im Falle der vorliegenden Erfindung darum, ein derartiges Drehmoment auch auf das in Öffnungsrichtung jeweils nachfolgende Flügelpaar 2 oder 3 gewissermaßen autotisch aufbringen zu können, damit auch dieses Flügelpaar 2 oder 3 aus seiner Schließlage heraus eingeknickt bzw eingeklappt wird.In the case of the present invention, the aim is to be able to apply such a torque to the pair of wings 2 or 3 following in the opening direction, so to speak, so that this pair of blades can also be applied automatically 2 or 3 is buckled or folded out of its closed position.

Es versteht sich, daß die gleiche Problematik bei weiteren Flügelpaaren immer gleichartig entsteht und daß für die Überwindung dieses Problems immer die gleichen Lösungsmittel Verwendung finden.It goes without saying that the same problem always arises in the same way for other wing pairs and that the same solvents are always used to overcome this problem.

Wie nun speziell aus den Figuren 2 bis 4 hervorgeht, ist an den beiden im Scharnierbereich zweier benachbarter Flügelpaare 2 und 3 liegenden Flügel 2a und 3a jeweils ein Mitnehmer 7 befestigt und an der gemeinsamen Trageinrichtung 5 sind zwei zweiarmige Hebel 8 angeordnet, welche jeweils um eine parallel zur Scharnierachse verlaufende Drehachse 9 schwenkbar sind und von denen jeweils ein Hebelarm 8a im Schwenkbereich des zugeordneten Mitnehmers 7 liegt und deren jeweils anderer Hebelarm 8b sich bis in den Bereich des Flügels 2a bzw. 3a erstreckt, der dem mit dem Mitnehmer 7 ausgestatteten Flügel 2a oder 3a benachbart ist.As can be seen specifically from FIGS. 2 to 4, a driver 7 is fastened to each of the two wings 2a and 3a lying in the hinge area of two adjacent pairs of wings 2 and 3, and two two-armed levers 8 are arranged on the common support device 5, each by one Axis of rotation 9 running parallel to the hinge axis and each of which a lever arm 8a lies in the pivoting range of the associated driver 7 and the other lever arm 8b of which extends into the area of the wing 2a or 3a which corresponds to the wing 2a equipped with the driver 7 or 3a is adjacent.

Insbesondere die Figuren 3 und 4 machen nun deutlich, daß bei der Öffnung eines Flügelpaares - im dargestellten Ausführungsbeispiel des Flügelpaares 3 - der am Flügel 3a befestigte Mitnehmer 7 ab einem bestimmten Schwenkbereich des betreffenden Flügels 3a ein Drehmoment auf den zugeordneten zweiarmigen Hebel 8 ausübt bedingt dadurch, daß der Mitnehmer 7 auf den Hebelarm 8a einwirkt. Die entsprechende Kraft wird über den zweiten Hebelarm 8b auf den benachbarten Flügel 2a übertragen und bewirkt dort die Ausübung eines Drehmomentes auf diesen Flügel 2a, was ein Einknicken des nachfolgenden Flügelpaares 2 zur Erleichterung der Öffnungsbewegung auch dieses nachfolgenden Flügelpaares 2 zur Folge hat.In particular, Figures 3 and 4 make it clear that when a pair of wings is opened - in the illustrated embodiment of the pair of wings 3 - the driver 7 attached to the wing 3a exerts a torque on the associated two-armed lever 8 from a certain pivoting range of the wing 3a in question because of this that the driver 7 acts on the lever arm 8a. The corresponding force is transmitted to the adjacent wing 2a via the second lever arm 8b and there causes a torque to be exerted on this wing 2a, which causes the subsequent wing pair 2 to buckle to facilitate the opening movement of this subsequent wing pair 2 as well.

Würde hingegen analog das Flügelpaar 2 als erstes manuell geöffnet, so würde über den am Flügel 2a befestigten Mitnehmer 7 der entsprechend zugeordnete zweiarmige Hebel 8 betätigt, dessen Hebelarm 8b in diesem Falle dem benachbarten Flügel 3a im Sinne des Einknickens beaufschlagen würde.If, on the other hand, the pair of wings 2 were opened manually first, the correspondingly assigned two-armed lever 8 would be actuated via the driver 7 attached to the wing 2a, the lever arm 8b of which in this case would act on the adjacent wing 3a in the sense of buckling.

Die Anordnung zweier Mitnehmer 7 und zweier Hebel 8 ist dann erforderlich, wenn die Falttür - wie im Ausführungsbeispiel dargestellt - nach beiden Seiten hin geöffnet werden kann.The arrangement of two drivers 7 and two levers 8 is required when the folding door - as shown in the embodiment - can be opened on both sides.

Ist hingegen ein endseitiges Flügelpaar 2 oder 3 festgelegt, genügt die Anordnung eines Mitnehmers 7 und eines Hebels 8, um das vorstehend beschriebene Einknicken des jeweils nachfolgenden Flügelpaares zu bewirken.If, on the other hand, an end pair of wings 2 or 3 is fixed, the arrangement of a driver 7 and a lever 8 is sufficient to bring about the buckling of the subsequent pair of wings described above.

Die Figur 2 macht deutlich, daß die Hebel 8 an einer als Scharnierträger ausgebildeten Trageinrichtung 5 angeschlossen sind. Es handelt sich hier um eine bekannte und deshalb nicht weiter beschriebene Trageinrichtung 5 in Form eines etwa U-förmigen Bügels 10, der einerseits als Scharnierträger und andererseits als Laufrollenträger dient.FIG. 2 makes it clear that the levers 8 are connected to a support device 5 designed as a hinge support. This is a known and therefore not further described support device 5 in the form of an approximately U-shaped bracket 10, which serves on the one hand as a hinge support and on the other hand as a roller support.

Da die beiden Hebel 8 an dieser bekannten Trageinrichtung 5 unmittelbar befestigt sind und außerdem nicht weiter über die zugeordneten Flügel 2a und 3a hinaus vorstehen als um das blaß der Trageinrichtung 5 selbst, ist die wie vorstehend beschriebene Öffnungshilfe für die gesamte Falttür äußerst platzsparend, was insbesondere dann von großem Vorteil ist, wenn der hinter einer derartigen Falttür 1 befindliche Raum möglichst optimal genutzt werden soll, beispielsweise bei einem Schrank.Since the two levers 8 are directly attached to this known support device 5 and also do not protrude beyond the associated wings 2a and 3a beyond the pale color of the support device 5 itself, the opening aid described above is extremely space-saving, which in particular It is of great advantage if the space behind such a folding door 1 is to be used as optimally as possible, for example in a cupboard.

Da die Öffnungshilfe letztendlich auch nur aus einfachen Bauteilen besteht, ist sie auch einfach und preiswert herstellbar.Since the opening aid ultimately only consists of simple components, it is also simple and inexpensive to manufacture.

Zur Erleichterung der Bewegungsübertragungen von den Mitnehmern auf die Hebel 8 einerseits und den Hebelarmen 8b auf die Flügel 2a und 3a andererseits sind die Mitnehmer 7 und die Hebelarme 8b mit Gleitrollen 11 ausgestattet.To facilitate the transmission of movement from the drivers to the levers 8 on the one hand and the lever arms 8b to the wings 2a and 3a on the other hand, the drivers 7 and the lever arms 8b are equipped with sliding rollers 11.

Abweichend von dem in den Figuren 3 bis 4 dargestellten Ausführungsbeispiel ist es natürlich auch denkbar, die Mitnehmer 7 und die Hebel 8 im mittleren Bereich der Flügel 2a und 3a zu montieren oder sowohl im oberen wie auch im unteren Endbereich derartige Mitnehmer 7 und Hebel 8 anzubringen.Deviating from the exemplary embodiment shown in FIGS. 3 to 4, it is of course also conceivable to mount the drivers 7 and the levers 8 in the central region of the wings 2a and 3a or to mount such carriers 7 and levers 8 both in the upper and in the lower end region .

Dies hängt letztendlich vorrangig vom Gewicht der Flügel 2a und 3a ab.Ultimately, this depends primarily on the weight of the wings 2a and 3a.

Die Figuren 5 bis 7 machen deutlich, daß auch bei Trageinrichtungen 5 in Form von Scharnierträgern mit Doppelscharnieren - insbesondere wieder für schwere Flügel 2a und 3a - die Mitnehmer 7 und die Hebel 8 im Bereich zwischen den Scharnieren 12 platzsparend angeordnet sein können.Figures 5 to 7 make it clear that even with support devices 5 in the form of hinge brackets with double hinges - especially again for heavy wings 2a and 3a - the driver 7 and the lever 8 in the area between the hinges 12 can be arranged to save space.

Werden zwei benachbarte Flügelpaare 2 und 3 in bekannter Weise an durchlaufenden Lisenen anscharniert, können die Hebel 8 in entsprechenden Ausnehmungen dieser Lisenen problemlos montiert sein.If two adjacent pairs of wings 2 and 3 are hinged in a known manner to continuous pilaster strips, the levers 8 can be mounted in corresponding recesses in these pilaster strips without any problems.

Die Anbringung der Mitnehmer 7 und der Hebel 8 ist montagetechnisch unproblematisch, insbesondere ist es auch denkbar, bereits bestehende Falttüren mit derart gestalteten Öffnungshilfen nachzurüsten.The attachment of the driver 7 and the lever 8 is unproblematic in terms of assembly, in particular it is conceivable to retrofit existing folding doors with opening aids designed in this way.

Sowohl die Mitnehmer 7 wie auch die Hebel 8 sind vorzugsweise aus Kunststoff gefertigt. Das gleiche gilt für die Gleitrollen 11.Both the driver 7 and the lever 8 are preferably made of plastic. The same applies to the sliding rollers 11.

Durch entsprechende Gestaltung der Hebel 8 und der Mitnehmer 7 kann festgelegt werden, ab welchem Öffnungswinkel die erwünschte Öffnungshilfe in Kraft tritt. Ebenso kann durch entsprechende Dimensionierung der Hebel 8 sichergestellt werden, daß das auf den nachfolgenden Flügel ausgeübte Drehmoment im Sinne der erwünschten Öffnungshilfe ausreichend groß ist.By appropriate design of the lever 8 and the driver 7 it can be determined from which opening angle the desired opening aid comes into force. Likewise, appropriate dimensioning of the lever 8 can ensure that the torque exerted on the following leaf is sufficiently large in the sense of the desired opening aid.
