Abstract
Description
Die Anmeldung betrifft ein Rastgelenk, insbesondere zur Positionierung eines Rücken- oder eines Fußteiles an Sitz- und Liegemöbeln nach dem Oberbegriff des Anspruches 1.The Application relates to a locking joint, in particular for positioning a back or a foot part on sitting and lying furniture according to the preamble of claim 1.
Es sind Rastgelenke für den vorher genannten Einsatzzweck bekannt, bei denen die beiden Gelenkarme über ein Ratschengetriebe miteinander gekoppelt sind. Bei einem solchen Ratschengetriebe greift in den Feststellpositionen eine Klinke mit ein bis zwei Rastzähnen in einen stirnseitig teilverzahnten Kranz am anderen Gelenkarm ein. Die am anderen Gelenkarm vorgesehene Klinke ist zur Aufhebung der Rücklaufsperre in eine Endposition verschwenkbar, derart, dass der oder die Eingriffszähne aus dem Zahnbereich herausgelangen. In der Regel ist die Klinke dabei gegen einen Rückstellfederdruck betätigbar.It are locking joints for known the aforementioned purpose in which the two Articulated arms over a ratchet gear are coupled together. In such a Ratchet gear engages in the locking positions with a pawl one to two ratchet teeth in a frontally partially toothed ring on the other articulated arm. The provided on the other articulated arm pawl is to lift the Backstop pivoted to an end position, such that the one or more engagement teeth get out of the tooth area. As a rule, the latch is included against a return spring pressure actuated.
Nachteil bei diesem Stand der Technik ist die geringe Zahl von miteinander kämmenden Zähnen. In Anbetracht der zu berücksichtigenden Hebelarme, die sich bei Sitz- und Liegemöbeln bezüglich des verschwenkbaren Rücken- oder Fußteiles ergeben, sind die Zahnbelastungen sehr hoch. Es besteht die Gefahr des Abbrechens von Zähnen, beispielsweise, wenn das Fußteil mit relativ hohem Gewicht belastet wird. Dementsprechend werden bei den bekannten Konstruktionen die miteinander kämmenden Zahnelemente mit hohen Festigkeitswerten eingesetzt.disadvantage in this prior art, the small number of each other meshing Teeth. In Considering the one to be considered Lever arms, which in seating and reclining furniture with respect to the pivoting back or foot section result, the tooth loads are very high. There is a danger the breaking off of teeth, for example, if the foot part is loaded with a relatively high weight. Accordingly, become in the known constructions intermeshing Toothed elements with high strength values used.
Die Aufgabe der Erfindung besteht darin, ein Rastgelenk der eingangs genannten Art vorzuschlagen, bei dem in den Rücklauf gesperrten Positionen möglichst viele Zähne von entsprechenden Getriebelementen ineinander greifen, so dass die entsprechenden Flächenpressungen im Bereich der Zahnflanken niedriger sind.The The object of the invention is a locking joint of the above mentioned type suggest possible in the locked in the return positions many teeth mesh of corresponding gear elements, so that the appropriate surface pressures are lower in the region of the tooth flanks.
Gelöst wird die Erfindungsaufgabe mit einem Rastgelenk mit den Merkmalen des Anspruchs 1. Bei einer solchen erfindungsgemäßen Konstruktion kämmen jeweils zwei Rastzahnkränze in der rücklaufgesperrten Position über einen Winkelbereich von 360° miteinander. Die Kraftbelastung ist daher an den einzelnen Zähnen gegenüber den Konstruktionen nach dem Stand der Technik deutlich geringer, so dass diese erfindungsgemäßen Rastgelenke sehr viel sicherer sind und auch den Einsatz von Materialien mit geringeren Festigkeitseigenschaften ermöglichen.Is solved the invention task with a locking joint with the features of Claim 1. In such a construction according to the invention comb respectively two ratchet rings in the reverse-locked Position over an angular range of 360 ° with each other. The force load is therefore at the individual teeth opposite the constructions after the State of the art significantly lower, so that these locking joints invention are much safer and also using materials with allow lower strength properties.
Gemäß Anspruch 2 wird für das erfindungsgemäße Rastgelenk eine geeignete Abhebvorrichtung für das axial verschiebbare Zahnkranzelement vorgeschlagen, welches in einfacher Weise in einer Endposition des zu verschwenkenden Gelenkarmes die Rücklaufsperre aufhebt, um damit eine Rückstellposition in andere Ausgangslagen zu ermöglichen.According to claim 2 will be for the locking joint according to the invention proposed a suitable lifting device for the axially displaceable sprocket element, which in a simple manner in an end position of the to be pivoted Articulated arm the backstop repeals, thereby creating a reset position into other starting positions.
Insbesondere aus optischen Gründen ist gemäß Anspruch 3 das axial verschiebbare Rastzahnkranzelement mit der Rückstellfeder in einem offenen Gehäuse am ersten Gelenkarm geführt aufgenommen. Dadurch ist das gesamte Getriebe nach außen abgedeckt.Especially for visual reasons is according to claim 3, the axially displaceable latching ring element with the return spring in an open case guided on the first articulated arm added. As a result, the entire transmission is covered to the outside.
