Abstract

A limiting stop for the swinging angle of an arm which is pivotally mounted on a fixed structure. The stop consists of a pair of parallel links which are connected for relative sliding motion between at contracted position and an extended position. At least one of the links has an elongated slot and the other link has a laterally projecting tongue which extends into the slot for movement along the slot. One end of the slot has a stopping surface which is engaged by the tongue when the links are in the extended position for determining the swinging angle of the arm.

Description

Die Erfindung betrifft einen Begrenzungsanschlag für den Schwenkwinkel eines um eine Lagerachse beweglichen Armes, bei welchem eine Strebe einerseits an dem die Lagerachse tragenden Bauteil angelenkt ist und an­dererseits am Arm im Abstand von der Lagerachse angreift.The invention relates to a limit stop for the pivot angle of an arm movable about a bearing axis, in which a strut is articulated on the one hand on the component supporting the bearing axis and on the other hand engages the arm at a distance from the bearing axis.

Derartige Begrenzungsanschläge werden beispielsweise auf dem Entwick­lungsgebiet der Baubeschläge oft benötigt. So werden sie beispielsweise benutzt, um den Öffnungswinkel von Ausstellarmen für Fenster und Türen relativ zum feststehenden Rahmen und/oder zum Flügel zu begrenzen.Such limit stops are often required, for example, in the development area of building hardware. For example, they are used to limit the opening angle of opening arms for windows and doors relative to the fixed frame and / or the sash.

Der für die Unterbringung solcher Begrenzungsanschläge verfügbare Einbau­raum ist dabei oft relativ gering. Trotzdem ist es aber wichtig, daß die Begrenzungsanschläge die ihnen zugedachte Funktion dauerhaft sicher er­füllen.The installation space available for accommodating such limit stops is often relatively small. Nevertheless, it is important that the limit stops perform their intended function safely in the long term.

Nach der Erfindung wird ein gattungsgemäßer Begrenzungsanschlag geschaffen, der bei relativ geringem Einbauraum und hoher Funktionssicherheit eine bauliche einfache Ausgestaltung aufweist. Ein solcher Begrenzungsanschlag zeichnet sich durch die Kennzeichnungsmerkmale des Anspruchs 1, nämlich dadurch, aus, daß die Strebe aus zwei baugleichen Laschen mit je einem Längsschlitz und einer diesem mit Abstand vorgelagerten sowie aus der Laschenebene abgewinkelten Anschlagzunge besteht, daß die Anschlagzunge jeder Lasche jeweils in den Längsschlitz der anderen Lasche ausschließlich längsschiebbar eingerückt ist, daß das Anschlagende des Längsschlitzes jeder Lasche deren Anschlagzunge benachbart liegt, daß jede Anschlagzunge an ihrem Ende seitwärts auskragende Stütznasen aufweist, die lediglich im Bereich einer erweiterten, vom Anschlagende des Längsschlitzes entfernten Endausklinkung mit den Längskanten des Längsschlitzes in den Laschen in Stützeingriff bringbar ist, und daß die Relativverschiebung der Laschen auf ein Maß begrenzbar ist, das den Abstand zwischen dem Anschlagende und der erweiterten Endausklinkung der Längsschlitze beider Laschen unterschreitet.According to the invention, a generic limit stop is created which has a simple construction with a relatively small installation space and high functional reliability. Such a limit stop is characterized by the characterizing features of claim 1, namely characterized in that the strut consists of two structurally identical tabs, each with a longitudinal slot and a stop tongue in front of it and angled from the tab plane, in that the stop tongue of each tab is only pushed longitudinally into the longitudinal slot of the other tab, so that the stop end of the Longitudinal slot of each tab whose stop tongue is adjacent, that each stop tongue has sideways projecting support lugs, which can only be brought into support engagement with the longitudinal edges of the longitudinal slot in the tabs in the region of an enlarged end notch from the stop end of the longitudinal slot, and that the relative displacement of the Tabs can be limited to a dimension that is less than the distance between the stop end and the extended end notch of the longitudinal slots of both tabs.

Nach Anspruch 2 können erfindungsgemäß die voneinander abgewendeten Enden beider Laschen lediglich schwenkbar einerseits an dem die Lager­achse tragenden Bauteil und andererseits am Arm angelenkt sein, während Anspruch 3 vorsieht, daß die Laschen der Strebe aus Bandmaterial mit flach­rechteckigem Querschnitt bestehen.According to claim 2, the mutually facing ends of the two tabs can only be pivoted on the one hand to the bearing-bearing component and on the other hand to the arm, while claim 3 provides that the tabs of the strut consist of strip material with a flat rectangular cross-section.

Es liegt auf der Hand, daß die Laschen zur Bildung eines erfindungsgemäßen Begrenzungsanschlags leicht und einfach als Stanzbiegeteile gefertigt werden können und daß sich dabei jeweils zwei dieser Laschen durch einfache Steck­kupplungsverbindungen zu einer als Begrenzungsanschlag dienenden, innerhalb vorgegebener Grenzen längerverstellbaren Strebe zusammensetzen lassen.It is obvious that the tabs for forming a limit stop according to the invention can be easily and simply manufactured as stamped and bent parts, and that two of these tabs can be put together by simple plug-in coupling connections to form a strut which serves as a limit stop and can be adjusted within predetermined limits.

In der Zeichnung ist der Gegenstand der Erfindung in einem Ausführungsbei­spiel dargestellt. Es zeigt

  • Fig. 2 einen Längsschnitt durch den Begrenzungsanschlag nach Fig. 1 in Ruhestellung bzw. zusammengescho­benem Zustand.
In the drawing, the object of the invention is shown in one embodiment. It shows

  • Fig. 2 shows a longitudinal section through the limit stop of FIG. 1 in the rest position or pushed together.

In Fig. 1 der Zeichnung ist in schematisch vereinfachter Darstellung, nämlich durch eine strichpunktierte Linie, der feststehende Rahmen 1 eines Fensters, einer Tür od. dgl. gezeigt, an dem über ein Trag- und Führungslenkersystem 2 ein Flügel 3 schwenkbeweglich aufgehängt ist.In Fig. 1 of the drawing is shown in a schematically simplified representation, namely by a dash-dotted line, the fixed frame 1 of a window, a door or the like, on which a wing 3 is pivotally suspended via a support and guide link system 2.

Das Trag- und Führungslenkersystem 2 weist dabei einen Tragarm 4 auf, der um eine Lagerachse 5 schwenkbeweglich am feststehenden Rahmen 1 aufgehängt ist. Mit dem Tragarm 4 sind über zwei Gelenkzapfen 6 und 7 zwei Lenker 8 und 9 verbunden, die eine übereinstimmende Längenabmessung haben. Jeder der Lenker 8 und 9 ist dabei wiederum über je einen Gelenk­zapfen 10 bzw. 11 an eine Führungsschiene 12 angeschlossen, die am Flügel 3, parallel zu dessen Ebene liegende, festgelegt werden kann. Der zwischen den Gelenkzapfen 6 und 7 gelegene Teilabschnitt des Tragarms 4 bildet mit den beiden Lenkern 8 und 9 sowie mit der die beiden Gelenkzapfen 10 und 11 tragenden Führungsschiene 12 ein Lenkerparallelogramm 13, welches den Flügel 3 mit dem feststehenden Rahmen 1 verbindet. Die Bewegung des Lenkerparallelogramms 13 wird dabei durch einen Steuerlenker 14 beeinflußt, der einerseits um einen Gelenkzapfen 15 schwenkbar am feststehenden Rahmen aufgehängt ist und andererseits mit einem Gelenkzapfen 16 zwischen den Gelenkzapfen 6 und 10 am Lenker 8 angreift. Der Steuerlenker 14 wirkt dabei auf das Lenkerparallelogramm 13 so ein, daß der Flügel 3 bei seiner Öffnungs- und Schließbewegung längs einer Bahn geführt wird, die wenigstens annähernd von Kreisbogen um eine latente Gelenkachse begrenzt ist, die in der Nähe der den Lagerstellen 5 und 15 benachbarten Seitenkante des Flügels 3 liegt.The support and guide link system 2 has a support arm 4 which is suspended on the fixed frame 1 so as to be pivotable about a bearing axis 5. With the support arm 4 two links 8 and 9 are connected via two pivot pins 6 and 7, which have a matching length dimension. Each of the links 8 and 9 is in turn connected via a respective pivot pin 10 or 11 to a guide rail 12 which can be fixed on the wing 3, lying parallel to its plane. The section of the support arm 4 located between the pivot pins 6 and 7 forms, with the two links 8 and 9 and with the guide rail 12 carrying the two pivot pins 10 and 11, a link parallelogram 13 which connects the wing 3 to the fixed frame 1. The movement of the handlebar parallelogram 13 is influenced by a control link 14 which is pivotally suspended on the one hand on the fixed frame about a pivot pin 15 and on the other hand engages with a pivot pin 16 between the pivot pins 6 and 10 on the handlebar 8. The control arm 14 acts on the parallelogram 13 so that the wing 3 is guided in its opening and closing movement along a path which is at least approximately delimited by a circular arc around a latent hinge axis which is in the vicinity of the bearing points 5 and 15 adjacent side edge of the wing 3 is.

Damit Beschädigungen am Fenster oder an der Tür sowie an den Trag- und Führungslenkersystemen 2 vermieden werden, ist es notwendig, den Schwenk­ winkel für den Tragarm 4 um seine Lagerachse 5, beispielsweise auf 90° zur Ebene des feststehenden Rahmens 1, zu begrenzen. Als Begrenzungs­anschlag für den Schwenkwinkel des Tragarmes 4 wird daher eine Strebe 17 benutzt, die einerseits und den Gelenkzapfen 18 am feststehenden Rahmen 1 schwenkbeweglich aufgehängt ist und andererseits am Tragarm 4, beispiels­weise über den Gelenkzapfen 6, im Abstand von der Lagerachse 5 angreift.In order to avoid damage to the window or door as well as to the support and guide link systems 2, it is necessary to pivot Angle for the support arm 4 to limit its bearing axis 5, for example to 90 ° to the level of the fixed frame 1. A strut 17 is therefore used as a limit stop for the pivoting angle of the support arm 4, which is pivotally suspended on the one hand and the articulation pin 18 on the fixed frame 1 and on the other hand acts on the support arm 4, for example via the articulation pin 6, at a distance from the bearing axis 5.

Die Strebe 17 wird dabei von zwei baugleichen Laschen 19a und 19b ge­bildet. Jede dieser Laschen 19a und 19b weist einen Längsschlitz 20a bzw. 20b auf und ist darüberhinaus mit einer aus der Laschenebene abgewinkelten Anschlagzunge 21a bzw. 21b versehen.The strut 17 is formed by two identical tabs 19a and 19b. Each of these tabs 19a and 19b has a longitudinal slot 20a or 20b and is also provided with a stop tongue 21a or 21b angled out of the tab plane.

Die Anschlagzunge 21a bzw. 21b jeder Lasche 19a bzw. 19b greift jeweils in den Längsschlitz 20b bzw. 20a der anderen Lasche 19b bzw. 19a ausschließ­lich längsverschiebbar ein. Dabei ist das Anschlagende 22b bzw. 22a des Längsschlitzes 20b bzw. 20a jeder Lasche 19b bzw. 19a benachbart von deren Anschlagzunge 21b bzw. 21a vorgesehen.The stop tongue 21a or 21b of each bracket 19a or 19b engages in the longitudinal slot 20b or 20a of the other bracket 19b or 19a only in a longitudinally displaceable manner. The stop end 22b or 22a of the longitudinal slot 20b or 20a of each tab 19b or 19a is provided adjacent to its stop tongue 21b or 21a.

In der aus Fig. 1 ersichtlichen, ausgezogenen Endstellung der Strebe 17 wird der Abstand zwischen deren Anlenkachsen 6 und 18 auf das Maß 23 begrenzt. Bei dieser ausgezogenen Länge der Strebe 17 wirkt dann die Anschlagzunge 21a der Lasche 20a mit dem Anschlagende 22b im Längsschlitz 20b der Lasche 19b zusammen, während umgekehrt die Anschlagzunge 21b der Lasche 19b am Anschlagende 22a im Längsschlitz 20a der Lasche 19a zur Anlage kommt, wie das deutlich der Fig. 1 entnommen werden kann.In the extended end position of the strut 17 shown in FIG. 1, the distance between the articulation axes 6 and 18 thereof is limited to the dimension 23. With this extended length of the strut 17, the stop tongue 21a of the bracket 20a then interacts with the stop end 22b in the longitudinal slot 20b of the bracket 19b, while conversely the stop tongue 21b of the bracket 19b comes into contact with the stop end 22a in the longitudinal slot 20a of the bracket 19a, as is the case 1 can be clearly seen.

Damit die die Strebe 17 bildenden Laschen 19a und 19b auf einfache Art und Weise zusammengebaut und zusammengehalten werden können, weist jede Anschlagzunge 21a und 21b an ihrem freien Ende seitwärts auskragende Stütznasen 24a bzw. 24b auf. Diese Stütznasen 24a bzw. 24b können ledig­lich im Bereich einer erweiterten Endausklinkung 25a bzw. 25b, die dem vom Anschlagende 22a bzw. 22b entfernten Ende des Längsschlitzes 20a bzw. 20b zugeordnet ist, mit den Längskanten der Längsschlitze 20a bzw. 20b in Stütz- und Halteeingriff gebracht werden.So that the straps 17a and 19b forming the strut 17 can be assembled and held together in a simple manner, each stop tongue 21a and 21b has, at its free end, laterally projecting support lugs 24a and 24b. These support lugs 24a and 24b can only in the region of an enlarged end notch 25a or 25b, the end of the longitudinal slot 20a remote from the stop end 22a or 22b or 20b is assigned to be brought into support and holding engagement with the longitudinal edges of the longitudinal slots 20a or 20b.

Nach dem Zusammensetzen der beiden Laschen 19a und 19b zur Strebe 17 wird dann die Relativverschiebung der Laschen 19a und 19b zueinander auf ein Maß 26 begrenzt, das den Abstand zwischen dem Anschlagende 22a bzw. 22b und der erweiterten Endausklinkung 25a bzw. 25b der Längsschlitze 20a und 20b beider Laschen 19a und 19b unterschreitet. Einem unerwünschten und selbsttätigen Entkuppeln der die Strebe 17 bildenden beiden Laschen 19a und 19b wird dadurch auf einfache Art und Weise entgegengewirkt.After the assembly of the two tabs 19a and 19b to the strut 17, the relative displacement of the tabs 19a and 19b to one another is then limited to a dimension 26 which is the distance between the stop end 22a or 22b and the extended end notch 25a or 25b of the longitudinal slots 20a and 20b falls below both tabs 19a and 19b. An undesired and automatic decoupling of the two straps 17a and 19b forming the strut 17 is thereby counteracted in a simple manner.

Die beiden Laschen 19a und 19b der Strebe 17 sind baulich völlig identisch gestaltet und können daher in ein und demselben Werkzeug, vorzugsweise aus Bandmaterial mit flach-rechteckigem Querschnitt, als Stanzbiegeteile gefertigt werden. Wichtig ist dabei, daß die Anschlagzungen 21a und 21b der beiden Laschen 19a und 19b in die ihnen zugeordneten Längsschlitze 20b und 20a lediglich längsverschiebbar eingreifen, während die freien Enden der Strebe 17 auf den Gelenkzapfen 6 und 18 lediglich schwenkbeweglich gehalten sind.The two tabs 19a and 19b of the strut 17 are structurally completely identical and can therefore be manufactured as stamped and bent parts in one and the same tool, preferably from strip material with a flat rectangular cross section. It is important that the stop tongues 21a and 21b of the two tabs 19a and 19b only engage in the longitudinal slots 20b and 20a assigned to them in a longitudinally displaceable manner, while the free ends of the strut 17 are only pivotably held on the pivot pins 6 and 18.

Selbstverständlich ist die Benutzung der Strebe 17 als Begrenzungsanschlag für den Schwenkwinkel eines um eine Lagerachse beweglichen Armens nicht auf Trag- und Führungslenkersysteme 2 beschränkt, wie sie in Fig. 1 gezeigt sind. Vielmehr ist ein durch die Strebe 17 gebildeter Begrenzungsanschlag überall dort benutzbar, wo es darum geht, den Schwenkwinkel für einen um eine Lagerachse beweglichen Arm relativ zu dem die Lagerachse tragenden Bauteil zu begrenzen.Of course, the use of the strut 17 as a limit stop for the swivel angle of an arm movable about a bearing axis is not limited to support and guide link systems 2, as shown in FIG. 1. Rather, a limit stop formed by the strut 17 can be used wherever the aim is to limit the swivel angle for an arm movable about a bearing axis relative to the component carrying the bearing axis.

Abschließend sie noch erwähnt, daß es nach dem Zusammenbau der Laschen 19a und 19b zur Strebe 17 auch möglich ist, in die Endausklinkungen 25a und 25b der Längsschlitze 20a und 20b Füllstücke, z.B. aus Kunststoff, rastend einzudrücken, um dadurch das unerwünschte Entkuppeln zu verhindern.Finally she mentions that after assembling the tabs 19a and 19b to the strut 17 it is also possible to insert filler pieces, e.g. made of plastic, push in to prevent undesired decoupling.
