Abstract
Drehfallenschloß mit einer Tragplatte für eine zwischen einer Verriegelungsstellung und einer Entriegelungsstellung schwenkbare, eine Rastausnehmung aufweisende Drehfalle und eine Sperrklinke, welche in Verriegelungsstellung der Drehfalle mit einer Nase – unterstützt durch eine an der Nase befestigte Feder – in der Rastausnehmung gehalten ist, wobei nach Aufhebung der Rastverbindung die Drehfalle unter Federkraft in ihre Entriegelungsstellung verschwenkt wird, dadurch gekennzeichnet, daß das der Nase (9) abgewandte Ende (15) der Feder (14) die Bewegung der Drehfalle (2) aus der Verriegelungsstellung (
Description
Die Erfindung betrifft ein Drehfallenschloß entsprechend dem Oberbegriff des Patentanspruchs 1.The invention relates to a rotary latch lock accordingly the preamble of claim 1.
Ein derartiges Schloß ist aus offenkundiger Benutzung bekannt, beispielsweise ist es im VW-Bus vom Typ T4 zu finden und hat dort die Aufgabe, die umklappbare Rückenlehne in ihrer aufrechten Normalstellung zu verriegeln. Zu diesem Zweck ist dem lehnenfesten Drehfallenschloß ein an der Karosserieseitenwand befindlicher Schließbolzen zugeordnet, der in der Verriegelungsstellung formschlüssig vom Drehfallenschloß umgriffen wird. Durch Betätigung eines einstückig mit der Sperrklinke ausgebildeten Hebels kann die Verbindung aufgehoben werden, dabei schwenkt die Drehfalle aus ihrer Verriegelungsstellung in ihre Entriegelungsstellung.Such a lock is over known use, for example, it is in the VW bus from Type T4 to find and the task there is the foldable backrest lock in their upright normal position. To this end is the backrest-fixed rotary latch lock on the side wall of the body located locking bolt assigned the form-fitting in the locking position Swivel latch lock encircled becomes. By actuation one piece with the pawl trained lever the connection can be broken , the rotary latch swings out of its locked position in their unlocked position.
Dieses bekannte Drehfallenschloß weist zwei Federn auf. Eine Schraubenfeder ist mit einem ihrer Enden an der Nase der Sperrklinke, mit ihrem anderen Ende an der Tragplatte befestigt. Sie hat die Aufgabe, beim Zurückklappen der Rückenlehne aus ihrer vorgeklappten Stellung in die Normalstellung die Nase der Sperrklinke zwangsläufig in die Rastausnehmung der Drehfalle zu ziehen und dort zu halten, also eine selbsttätige Entriegelung im Fahrbetrieb – hervorgerufen durch Erschütterungen – zu verhindern. Die zweite Feder ist eine Schenkelfeder, die auf dem Lagerzapfen der Drehfalle angeordnet ist und mit einem ihrer Schenkel an der Tragplatte und mit dem anderen an der Drehfalle festgelegt ist. Im Verriegelungszustand des Drehfallenschlosses ist die Schenkelfeder gespannt. Beim Entriegeln, wenn also mittels des Sperrklinkenhebels die Nase der Sperrklinke aus der Rastausnehmung herausbewegt worden ist, verschwenkt die Schenkelfeder die Drehfalle in die Entriegelungssteliung.This well-known rotary latch lock has two Springs up. A coil spring is at one of its ends on the Latch of the pawl, with its other end attached to the support plate. It has the task of folding back the backrest the nose from its folded position to the normal position the pawl inevitably pull into the catch recess of the rotary latch and hold it there, so an automatic Unlocking while driving - caused through vibrations - to prevent. The second spring is a leg spring that is on the journal the catch is arranged and with one of its legs on the Support plate and with the other is fixed to the catch. The leg spring is in the locked state of the rotary latch lock curious; excited. When unlocking, i.e. by means of the pawl lever the nose of the pawl has been moved out of the recess the leg spring pivots the rotary latch into the unlocking position.
Der Erfindung liegt die Aufgabe zugrunde, bei einem gattungsgemäßen Drehfallenschloß durch Änderung der Federanordnung den Aufbau des Drehfallenschlosses wesentlich zu vereinfachen, ohne daß seine Funktion beeinträchtigt wird.The invention is based on the object a generic rotary latch lock by change the spring arrangement the structure of the rotary latch lock essential to simplify without his Function impaired becomes.
Diese Aufgabe wird mit den kennzeichnenden Merkmalen des Patentanspruchs 1 gelöst. Es können also die oben beschriebenen beiden Aufgaben der Federanordnung mit nur einer Feder erreicht werden, wenn diese erfindungsgemäß angeordnet wird. Dadurch können Material und diverse Arbeitsgänge bei der Herstellung des Drehfallenschlosses eingespart werden.This task is done with the characteristic Features of claim 1 solved. So it can be the ones described above both tasks of the spring arrangement can be achieved with only one spring, if this is arranged according to the invention. This allows Material and various operations can be saved in the manufacture of the rotary latch lock.
Zweckmäßigerweise ist die einzige Feder als Schraubenfeder ausgebildet.Conveniently, the only one Spring designed as a coil spring.
