The blocking unit is pivotably fastened at a strap (2) by a common pivoting axis (5) arranged centrally in the head, and is designed as a wedge-shaped blocking unit. The blocking unit movably rests against a stop edge (9) of the strap with its side turned away from the teeth of the blocking unit.

Description

Die Erfindung betrifft einen Rastbeschlag nach dem Oberbegriff des Anspruchs 1.The invention relates to a catch fitting according to the preamble of claim 1.

Solche Rastbeschläge werden eingesetzt, um Funktionsteile, wie Lehnen oder Kopfstützen aus einer Grundstellung in eine veränderte Stützstellung zu verschwenken. Dabei ist der das zu verschwenkende Teil tragende Rasthebel in unterschiedliche Winkelstellungen verschwenkbar und dort jeweils gegen ein Zurückschwenken arretierbar. Aus einer vorgeschwenkten Gebrauchs-Endstellung heraus kann das Funktionsteil freilaufend zurückverschwenkt werden, wozu die Arretierung außer Funktion gesetzt wird.Such locking fittings are used to pivot functional parts, such as backrests or headrests from a basic position in a modified support position. In this case, the latching lever carrying the part to be pivoted is pivotable into different angular positions and can be locked against pivoting back there. From a pre-pivoted use end position, the functional part can be pivoted backward, for which purpose the lock is disabled.

Ein gattungsgemäßer Rastbeschlag ist aus der DE 83 18 928 U1 bekannt. Zur Arretierung des schwenkbaren Rasthebels ist darin ein Klinkengesperre vorgesehen, das aus einer Außenverzahnung des Rasthebels und einer ein Sperrglied bildenden Sperrklinke besteht, die in der Arretierstellung in eine Zahnlücke der Außenverzahnung des Rasthebels eingreift.A generic catch fitting is from the DE 83 18 928 U1 known. For locking the pivotable locking lever a ratchet mechanism is provided therein, which consists of an external toothing of the locking lever and a locking member forming a pawl which engages in the locking position in a tooth gap of the external toothing of the locking lever.

Der Rasthebel und die Lasche, die üblicherweise an einem feststehenden Möbelteil befestigt ist, zu dem die Lehne oder Kopfstütze verschwenkbar ist, sind auf einer gemeinsamen Schwenkachse gelagert, wobei die Lasche den gebildeten Kopf des Rasthebels überdeckt.The locking lever and the tab, which is usually attached to a fixed furniture part to which the backrest or headrest is pivotable, are on one mounted common pivot axis, wherein the tab covers the formed head of the locking lever.

Grundsätzlich hat sich die Funktion dieses Rastbeschlages bewährt. Allerdings sind einige Nachteile zu erkennen, die zum einen die Handhabung beeinträchtigen und zum anderen die Platzierung, beispielsweise in einem Sitz-oder Liegemöbel, erschweren.Basically, the function of this detent fitting has been proven. However, some disadvantages can be seen, on the one hand affect the handling and on the other hand, the placement, for example, in a sitting or lying furniture complicate.

Letzteres deshalb, weil sich vor allem durch die Anordnung eines Ausklinkhebels, mit dem die Sperrklinke aus ihrem Wirkbereich herausgedrückt wird zur Entriegelung des Rastbeschlages und der auf den Rasthebel aufgesetzt ist, eine relativ große Bauhöhe ergibt. Dieser hohe Aufbau verhindert naturgemäß eine geforderte, Platz sparende Unterbringung von Funktionsbeschlägen.The latter, because above all by the arrangement of a release lever with which the pawl is pushed out of its effective range for unlocking the detent fitting and is placed on the locking lever, results in a relatively large overall height. This high construction naturally prevents a required, space-saving accommodation of functional fittings.

Bauartbedingt ist überdies die Zahnteilung der Außenverzahnung relativ groß, da die eingreifende Sperrklinke eine ausreichende Belastungsfähigkeit aufweisen muss, was in diesem Fall einer gewünschten feinstufigen Verstellung entgegensteht.Due to the design, moreover, the pitch of the external teeth is relatively large, since the engaging pawl must have sufficient load capacity, which in this case precludes a desired fine-scale adjustment.

Ein anderer Rastbeschlag der gattungsgemäßen Art ist aus der EP 1 510 150 B1 bekannt. Dieser bekannte Rastbeschlag weist einen ersten Arm, der mit einem Gehäuseabschnitt versehen ist, und einen zweiten Arm auf, der mit einem Gehäuseabschnitt des ersten Arms verbunden ist, so dass er um eine erste Achse oszilliert, wobei der zweite Arm mit einem Zahnradabschnitt versehen ist. Dabei ist bei dem bekannten Rastbeschlag ein Keilelement vorgesehen, das schwebend lose gelagert in einem Fenster des Gehäuseabschnitts angeordnet ist und in Riegelstellung mit seiner einen gezahnte Stirnseite in den Zahnradabschnitt des zweiten Arms eingreift. Zudem ist an der anderen Stirnseite des Keilelements eine Kontaktfläche vorhanden, die eine Keilfläche berührt, um auf diese Weise den zweiten Arm so in seiner Beweglichkeit einzuschränken, dass er in einer sich in Bezug auf den ersten Arm erstreckenden Richtung oszilliert. Dabei ist der Zahnradabschnitt des Keilelements so ausgebildet, dass er die erste Achse als Mitte aufweist.Another catch fitting of the generic type is from the EP 1 510 150 B1 known. This known detent fitting has a first arm provided with a housing portion and a second arm connected to a housing portion of the first arm so as to oscillate about a first axis, the second arm being provided with a gear portion. In this case, a wedge element is provided in the known catch fitting, which is floatingly mounted loosely arranged in a window of the housing portion and in the locked position engages with its one toothed end face in the gear portion of the second arm. In addition, at the other end face of the wedge member there is a contact surface which contacts a wedge surface so as to restrain the second arm in its mobility so as to oscillate in a direction extending with respect to the first arm. In this case, the gear portion of the wedge member is formed so that it has the first axis as the center.

Beim praktischen Gebrauch des aus der EP 1 510 150 B1 bekannten Rastbeschlags zeigt sich, dass seine Verriegelung in der jeweils gewünschten Schwenkstellung und seine Entriegelung zum Verändern der jeweiligen Schwenkstellung schwierig ist. Darüber hinaus neigen seine Verzahnungen zu vorzeitigem Verschleiß, was eine exakte Einstellung der Schwenkstellung zusätzlich erschwert.In practical use of the EP 1 510 150 B1 Known detent fitting shows that its locking in the respective desired pivot position and its unlocking for changing the respective pivot position is difficult. In addition, its teeth tend to wear prematurely, which further complicates an exact adjustment of the pivot position.

Der Erfindung liegt daher die Aufgabe zugrunde, einen kostengünstig herstellbaren Rastbeschlag der gattungsgemäßen Art mit konstruktiv geringem Aufwand so weiterzuentwickeln, dass er sich zuverlässig und exakt verstellen lässt.The invention is therefore based on the object, a cost-producible latching fitting of the generic type with structurally little effort so that he can be adjusted reliably and accurately.

Diese Aufgabe wird durch einen Rastbeschlag mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a catch fitting with the features of claim 1.

Durch diese konstruktive Ausgestaltung des Rastbeschlages ergeben sich eine ganze Reihe von Vorteilen gegenüber einem Rastbeschlag nach dem Stand der Technik.This structural design of the detent fitting results in a whole series of advantages over a detent fitting according to the prior art.

So ist zunächst einmal zu erwähnen, dass durch die keilförmige Ausbildung des Sperrgliedes eine räumlich sehr kleine Gestaltung möglich ist. Die Kraftübertragung in der Arretierstellung des Rasthebels erfolgt über die aneinander liegenden Keilflächen des Sperrgliedes einerseits und der Anschlagkante andererseits und nicht, wie beim Stand der Technik über die Verzahnung.So it should first be mentioned that a spatially very small design is possible by the wedge-shaped design of the locking member. The power transmission in the locking position of the locking lever via the contiguous wedge surfaces of the locking member on the one hand and the stop edge on the other hand and not, as in the prior art on the teeth.

Während der Rasthebel in Verschwenkstellung durch Einklemmen des Sperrgliedes zwischen der Anschlagkante der Lasche und der Verzahnung des Kopfes entgegen der Verschwenkrichtung arretiert ist, wird im weiteren Verlauf der Verschwenkung der Rasthebel über eine letzte verschwenkte Nutzstellung hinaus entriegelt, so dass er über seinen gesamten Schwenkbereich freilaufend zurückgeschwenkt werden kann in eine Ausgangsstellung.While the locking lever is locked in the pivoting position by clamping the locking member between the stop edge of the tab and the toothing of the head against the pivoting, is unlocked in the further course of pivoting the locking lever on a last pivoted use position out, so that it swung free-running over its entire pivoting range can be in a starting position.

Zur Entriegelung greift eine Drucknase an das Sperrglied an und bringt dies gegen die Kraft einer Druckfeder außer Eingriff mit der Verzahnung.For unlocking engages a pressure nose on the locking member and brings this against the force of a compression spring out of engagement with the teeth.

Vorzugsweise ist diese Drucknase ebenfalls auf der Schwenkachse gelagert. Dabei ist die Schwenkbewegung in eine Ausgangsstellung des Rasthebels durch einen daran angeschlossenen Anschlagbolzen begrenzt, der in einer Kulisse der Lasche geführt ist.Preferably, this pressure nose is also mounted on the pivot axis. The pivoting movement is limited to a starting position of the locking lever by a stopper bolt connected thereto, which is guided in a backdrop of the tab.

Die Erfindung erlaubt eine sehr feine Teilung der Verzahnung, wodurch sich die Anzahl der Raststellungen gegenüber dem Rastbeschlag nach dem Stand der Technik wesentlich vergrößert, mit der Folge einer Komfortverbesserung.The invention allows a very fine pitch of the teeth, whereby the number of locking positions relative to the locking fitting according to the prior art substantially increased, with the result of a comfort improvement.

Darüber hinaus zeichnet sich der neue Rastbeschlag durch seine fertigungstechnisch äußerst einfache Realisierung aus, die zu einer sehr kostengünstigen Herstellung führt.In addition, the new locking fitting is characterized by its manufacturing technology extremely simple implementation, which leads to a very cost-effective production.

Auch die Abmaße des neuen Rastbeschlages sind gegenüber dem bekannten verringert, wodurch sich ein verbesserter Einsatz in dem entsprechenden Möbel ergibt.The dimensions of the new detent fitting are reduced compared to the known, resulting in an improved use in the corresponding furniture.

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

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der beigefügten Zeichnungen beschrieben.An embodiment of the invention will be described below with reference to the accompanying drawings.

In den Figuren ist ein Rastbeschlag, insbesondere für verstellbare Lehnenteile eines Sitz- oder Liegemöbels gezeigt, der eine Lasche 2 sowie einen daran über eine Schwenkachse 5 verschwenkbaren Rasthebel 1 aufweist.In the figures, a detent fitting, in particular for adjustable backrest parts of a sitting or lying furniture is shown, which has a tab 2 and a pivotable about a pivot axis 5 locking lever 1.

Der Rasthebel 1 ist in dem der Schwenkachse 5 zugewandten Endbereich als ein kreisbogenförmiger Kopf 3 mit einer Außenverzahnung 4 ausgebildet und in Pfeilrichtung (Figur 3), entsprechend der Anzahl der Zähne der Außenverzahnung 4 in Raststellungen verschwenkbar.The locking lever 1 is formed in the pivot axis 5 facing the end portion as a circular arc-shaped head 3 with an external toothing 4 and in the direction of arrow ( FIG. 3 ), according to the number of teeth of the external teeth 4 in locking positions.

Um den Rasthebel 1 in der jeweiligen Raststellung zu arretieren, ist ein keilförmig ausgebildetes Sperrglied 6 vorgesehen, das einerseits mit Zähnen 7 versehen ist, die in die Außenverzahnung 4 des Kopfes 3 eingreifen und das auf einer gegenüberliegenden Seite an einer Anschlagkante 9 der Lasche 2 verschiebbar anliegt.In order to lock the locking lever 1 in the respective locking position, a wedge-shaped locking member 6 is provided, which is provided on the one hand with teeth 7 which engage in the external teeth 4 of the head 3 and the displaceable on an opposite side to a stop edge 9 of the tab 2 is applied.

Bei einer Belastung des Rasthebels 1 entgegen der durch den Pfeil in Figur 3 gekennzeichneten Schwenkrichtung, wird das Sperrglied 6 in den zwischen die Anschlagkante 9 und die Verzahnung 4 gebildeten Keilspalt gezogen, so dass der Rasthebel 1 in dieser Position arretiert ist.At a load of the locking lever 1 opposite to the arrow in FIG. 3 marked pivoting direction, the locking member 6 is pulled into the wedge gap formed between the stop edge 9 and the teeth 4, so that the locking lever 1 is locked in this position.

Unterstützt wird diese sozusagen Einzugsbewegung des Sperrgliedes 6 durch eine Druckfeder 8, die sich einerseits an einer Außenkante des Sperrgliedes 6 und andererseits an der Lasche 2 abstützt.This so-called retraction movement of the locking member 6 is supported by a compression spring 8, which is supported on the one hand on an outer edge of the locking member 6 and on the other hand on the tab 2.

Bei einer Verschwenkung in besagter Pfeilrichtung wird das Sperrglied 6 gegen die Kraft der Druckfeder 8 aus dem Keilspalt herausgedrückt, so dass der Rasthebel 1 gegenüber der Lasche 2 frei verschwenken kann.When pivoting in said direction of the arrow, the locking member 6 is pushed out against the force of the compression spring 8 from the wedge-shaped gap, so that the locking lever 1 can pivot freely relative to the tab 2.

Im Übrigen ist am Sperrglied 6 ein sich beidseitig erstreckender Zapfen 10 angeordnet, der auf einer Seite in einer Führung 13 der Lasche 2 geführt ist, wodurch die Bewegung des Sperrgliedes 6 begrenzt ist.Incidentally, on both sides of the locking member 6 extending pin 10 is arranged, which is guided on one side in a guide 13 of the tab 2, whereby the movement of the locking member 6 is limited.

Auf der anderen Seite dient der Zapfen 10 dem Ausrücken des Sperrgliedes 6 aus seiner Verkeilstellung, um den Rasthebel 1 aus einer verschwenkten Endstellung zurückzuschwenken in eine Ausgangsposition.On the other hand, the pin 10 serves the disengagement of the locking member 6 from its Verkeilstellung to zurückzuschwenken the locking lever 1 from a pivoted end position in a starting position.

Dabei korrespondiert der Zapfen 10, wie in den Figuren 4 und 5 sehr deutlich erkennbar ist, mit einer auf der Schwenkachse 5 gelagerten Drucknase 14.In this case, the pin 10 corresponds, as in the FIGS. 4 and 5 is very clearly visible, with a mounted on the pivot axis 5 pressure nose 14th

Zu deren Verdrehung im Sinne eines Drückens gegen den Zapfen 10 sind an dem Rasthebel 1, beidseitig der Drucknase 14, Druckstifte 15 befestigt, die sich gegenüberliegen.To their rotation in the sense of pressing against the pin 10, pressure pins 15 are fixed to the locking lever 1, on both sides of the pressure nose 14, which are opposite each other.

Bei der in der Figur 4 gezeigten Stellung, in der der Rasthebel 1 gegenüber der Lasche 2 in einer abgewinkelten Raststellung verharrt, sind die Zähne 4 des Sperrgliedes 6 mit der Verzahnung 7 in Eingriff.When in the FIG. 4 shown position in which the latching lever 1 relative to the tab 2 remains in an angled detent position, the teeth 4 of the locking member 6 with the teeth 7 in engagement.

Entsprechend der Pfeilrichtung in Figur 4 wird der Rasthebel 1 verschwenkt, unter jeweiliger Blockierung in den einzelnen, durch die Anzahl der Zähne vorgegebenen Rastpositionen, bis in eine Endstellung, die etwa der in der Figur 5 entspricht.According to the arrow direction in FIG. 4 the locking lever 1 is pivoted, with respective blocking in the individual, predetermined by the number of teeth locking positions, to an end position, which is approximately in the FIG. 5 equivalent.

Bei einer kurzen weiteren Verschwenkung des Rasthebels 1 wird einer der beiden Druckstifte 15, in der Figur 5 der rechte Druckstift 15, gegen die Drucknase 14 gedrückt, die den Zapfen 10 derart verschiebt, dass das Sperrglied 6 aus seiner Eingriffsstellung mit der Verzahnung 7 gebracht ist.In a short further pivoting of the locking lever 1, one of the two pressure pins 15, in the FIG. 5 the right pressure pin 15, pressed against the pressure nose 14, which moves the pin 10 such that the locking member 6 is brought out of its engaged position with the toothing 7.

In dieser in der Figur 5 erkennbaren Stellung verbleibt die Drucknase 14 und das Sperrglied 6 bis der Rasthebel 1 in eine Position verschwenkt wird, in der der linke Druckstift 15 gegen die Drucknase 14 stößt, und die Drucknase 14 verschwenkt, so dass der Zapfen 10 freiliegt und das Sperrglied 6 mittels der Druckfeder 8 in seine Eingriffsposition mit der Verzahnung 4 gebracht wird.In this in the FIG. 5 recognizable position remains the pressure nose 14 and the locking member 6 to the locking lever. 1 is pivoted to a position in which the left pressure pin 15 abuts against the pressure nose 14, and the pressure nose 14 is pivoted, so that the pin 10 is exposed and the locking member 6 is brought by the compression spring 8 in its engaged position with the teeth 4.

Zur Begrenzung des Schwenkweges des Rasthebels 1 ist, wie in der Figur 1 erkennbar, in der Lasche 2 eine kreisbogenförmige, konzentrische Kulisse 11 vorgesehen, in der ein Anschlagstift 12 der Rasthebels 1 geführt ist, wobei die Länge der Kulisse 11 den Schwenkweg des Rasthebels 1 begrenzt.To limit the pivoting of the locking lever 1, as in the FIG. 1 recognizable, in the tab 2 a circular arc-shaped, concentric gate 11 is provided, in which a stop pin 12 of the locking lever 1 is guided, wherein the length of the gate 11 limits the pivoting of the locking lever 1.

Alternativ kann die Schwenkbewegung des Rasthebels 1 auch durch die Druckstifte 15 begrenzt werden, wobei der in der Figur 4 erkennbare linke Druckstift 15 in einer Endstellung an einem Anschlag 16 der Lasche 2 zur Anlage kommt, während der rechte Druckstift 15 in der anderen Endstellung an der Drucknase 14 anliegt, die wiederum in ihrer Verschwenkung begrenzt ist, wie dies in der Figur 5 verdeutlicht ist. In diesem Fall kann auf die Kulisse 11 und den Anschlagstift 12 verzichtet werden.Alternatively, the pivoting movement of the locking lever 1 can also be limited by the pressure pins 15, wherein in the FIG. 4 recognizable left pressure pin 15 comes in an end position against a stop 16 of the tab 2 to the plant, while the right pressure pin 15 abuts in the other end position of the pressure nose 14, which in turn is limited in its pivoting, as shown in the FIG. 5 is clarified. In this case, can be dispensed with the backdrop 11 and the stopper pin 12.
