Abstract

The invention relates to a lock with a locking mechanism comprising a rotary latch - preferably at least partially composed of metal - with a load arm and a catch arm, which is rotatably mounted on a catch axis, and which can receive a cotter pin, characterised in that the distance between the inner end of the cotter pin and the contact point between cotter pin and load arm is shorter than the distance between the contact point between cotter pin and load arm and the outer end of the cotter pin. The opening forces of a vehicle lock are minimised as a result.

Description

Kraftfahrzeugs«: hloss  Motor vehicle «: hloss
Die Erfindung betrifft ein Schloss für ein Kraftfahrzeug mit den Merkmalen des Oberbegriffs von Anspruch 1 . The invention relates to a lock for a motor vehicle having the features of the preamble of claim 1.
Ein Schloss für ein Kraftfahrzeug umfasst ein Gesperre mit einer drehbar gelag erten Drehfalle für die Aufnahme eines Schließbolzens, der auch Schlossha lter gena nnt wird . Das Gesperre weist weiter eine Sperrklinke auf, mit der die Drehfalle für ein Halten des Schließbolzens verrastet werden kann. A lock for a motor vehicle comprises a locking mechanism with a rotatably mounted rotary catch for receiving a locking bolt, which is also suitable for locking. The locking mechanism further has a pawl with which the catch can be latched for holding the locking bolt.
Die Drehfalle eines Kraftfa hrzeugschlosses verfügt üblicherweise über einen durch Lastarm und Fa ngarm gebildeten gabelförmigen Einlaufsch litz (auch Einlaufmaul genannt) in den der Schließbolzen einer Fahrzeugtür oder Kla ppe, beispielsweise Motorhaube oder Kofferraumkla ppe, gelangt, wenn die Tür oder Klappe geschlossen wird . Der Schließbolzen bzw. Schlossha lter dreht dann die Drehfalle von einer Öffnungsstellung in Richtung Schließstellung, bis die Sperrklinke die Drehf alle verrastet. Diese Position wird Rastposition genannt. Der Schließbolzen kann den Einlaufschlitz der Drehfal le dann nicht verlassen. The catch of a Kraftfa vehicle lock usually has a ngarm by load arm and Fa fork-shaped Einlaufsch litz (also called inlet mouth) in the locking bolt of a vehicle door or Kla ppe, such as hood or Kofferraumkla ppe, passes when the door or flap is closed. The locking pin or Schlossha age then rotates the catch from an open position towards the closed position until the pawl the Drehf all locked. This position is called detent position. The locking pin can not leave the inlet slot of Drehfal le then.
Es gibt Kraftfahrzeugschlösser mit einer zwei Rastpositionen und zwar einer Vorrastposition und einer H auptrastposition. Die Vorrastposition dient dazu, die entsprechende Tür oder Klappe abzufangen, wenn diese beim Schließen die Hauptrastposition nicht erreicht. Wird die Drehfalle ausgehend von der Vorrastposition entsprech end weiter gedreht, so erreicht diese schließlich die H auptrastposition. Bei einem Kraftfa hrzeugsch loss wird u. a . aus Gründen der Bedienerfreundlichkeit angestrebt, dieses mit geringer Kraft öffnen zu können. Die Kraft, die für das Öffnen aufzuwenden ist, hängt in der H auptrastposition unter anderem von einem H ebelverhältnis zwischen Drehpunkt der Drehfalle und H auptrast (erster Hebel) sowie zwischen Drehpunkt der Drehfalle und Konta ktbereich bzw. Konta ktpunkt zwischen dem Schließbolzen und dem Lastarm (zweiter Hebel) ab. Der erste Hebel beginnt beim Mittelpunkt der Drehfalle und mündet senkrecht in die Richtung der Kraft ein, entläng der der Lastarm der Drehfalle in der Hau ptrastposition gegen die Sperrklinke drückt. Der zweite Hebel beginnt beim Mittelpun kt der Drehfallenac hse. Befindet sich das Gesperre in der Hauptrastposition, so übt der Schließbolzen eine Kraft aus, deren Richtung einen rechten Winkel mit dem zweiten Hebel einschließt, wie anhand der Figur 1 der DE 1 0 2009 029 01 6 A I veranschaulicht wird. Der zweite Hebel endet auf H öhe dieses Kraftpfeils. There are motor vehicle locks with a two locking positions and that a pre-locking position and a H auptrastposition. The pre-detent position serves to intercept the corresponding door or flap if it does not reach the main detent position when closing. If the catch, starting from the pre-latching position, is turned further, the latch finally reaches the home-latching position. In case of a power failure, u. a. for the sake of user-friendliness sought to be able to open this with little force. The force to be used for opening depends, among other things, on a balance between the two Fulcrum of the catch and H auptrast (first lever) and between the pivot point of the catch and Konta ktbereich or Konta ktpunkt between the locking pin and the load arm (second lever) from. The first lever starts at the center of the catch and opens vertically in the direction of the force, entläng the press arm of the catch in the Hau ptrastposition presses against the pawl. The second lever starts at the center point of the rotary traps. If the locking mechanism is in the main locking position, then the locking bolt exerts a force whose direction encloses a right angle with the second lever, as illustrated by FIG. 1 of DE 1 0 2009 029 01 6 AI. The second lever ends at the height of this force arrow.
Das Längenverhä ltnis zwischen dem ersten Hebel und dem zweiten Hebel wird Sperrteilverhältnis genannt. J e größer dieses Sperrteilverhältnis ist, umso geringer ist der für ein Entrasten eines Gesperres erforderliche Kraftaufwand . The Längenverhä ratio between the first lever and the second lever is called blocking part ratio. The larger this locking part ratio, the lower the force required for unlocking a locking mechanism.
Die DE 1 0 2009 029 01 6 A I Figur 1 offenbart ein an einer aus Metall bestehenden Platte eines Schlosskastens befestigtes Gesperre, bei dem das Sperrteilverhältnis 3 beträgt. Der Lastarm der Drehfalle ist deutlich breiter a ls ihr Fa ngarm ausgeführt ist. Der Fangarm verjüngt sich zu seinem offenen Ende hin, da dieses Ende am gerin gsten bel astet wird . So wird Material und Gewicht eingespart. I m Unterschied dazu wird der Lastarm zu seinem offenen Ende hin dicker, um sowohl eine Rastfläche für die Vorrastposition als auch eine Rastfläche für die H auptrastposition am Lastarm anord nen zu können . The DE 1 0 2009 029 01 6 A I Figure 1 discloses a mounted on a plate made of metal plate of a lock case locking in which the locking part ratio is 3. The load arm of the rotary latch is significantly wider than its handle arm. The tentacle tapers towards its open end, as this end is the least affected. This saves material and weight. In contrast to this, the load arm becomes thicker toward its open end in order to be able to arrange both a latching surface for the pre-latching position and a latching surface for the high-load latching position on the load arm.
Die Sperrklinke des Gesperres ist angrenzend an eine seitliche Schloss kastenwand angeordnet, so dass sich die Sperrklin ke gegen diese Schlosskastenwand abstützen kan n , wenn diese im Crashfall einer starken Kraft ausgesetzt werden sollte. Um ein günstiges Sperrteilverhältnis zu erzielen, wird gemäß der Druckschrift DE 102009029014 AI vorgeschlagen, den Abstand zwischen dem Schließbolzen und der Achse der Drehfalle in der Hauptrastposition zu minimieren. Aus Stabilitätsgründen sind die diesbezüglichen Möglichkeiten jedoch begrenzt. The pawl of the locking mechanism is arranged adjacent to a side lock box wall, so that the Sperrklin ke can be supported against this lock case wall kan n, if this should be exposed to a strong force in the event of a crash. In order to achieve a favorable blocking part ratio, it is proposed according to the document DE 102009029014 AI to minimize the distance between the locking pin and the axis of the rotary latch in the main detent position. For stability reasons, however, the possibilities are limited.
Bei den aus den Druckschriften DE 102009029014 AI sowie DE 102009 029 016 AI bekannten Schlössern mit Gesperre befindet sich die Achse der Drehfalle in einem Bereich, der den Lastarm mit dem Fangarm verbindet und zwar von der Seite mit dem außen liegenden Ende des Einlaufmauls entlang des zweiten Hebels aus gesehen hinter dem inneren Ende des Einlaufmauls. Eine solche Anordnung der Achse einer Drehfalle ist ferner aus den Druckschriften DE 102009026921 AI sowie DE 102010 003483 AI bekannt. In the known from the documents DE 102009029014 AI and DE 102009 029 016 AI locks with locking the axis of the catch is in an area that connects the load arm with the tentacle and that from the side with the outer end of the inlet mouth along the second Levers seen from behind the inner end of the inlet mouth. Such an arrangement of the axis of a rotary latch is also known from the publications DE 102009026921 AI and DE 102010 003483 AI.
Das innen liegende Ende bzw. das innere Ende des Einlaufmauls meint vom genannten Kontaktbereich oder Kontaktpunkt zwischen Schließbolzen und Lastarm aus gesehen das Ende, welches beim Grund des Drehfallen-Einlaufschlitzes liegt. Das außen liegende Ende meint vom besagten Kontaktpunkt zwischen Schließbolzen und Lastarm aus gesehen das Ende, welches in Richtung Öffnung des Einlaufschlitzes der Drehfalle liegt. The inner end or the inner end of the inlet mouth means from the said contact area or contact point between the locking pin and the load arm from the end, which lies at the bottom of the rotary latch inlet slot. The outer end of said contact point between the locking pin and load arm from the end, which lies in the direction of opening of the inlet slot of the rotary latch.
Die Druckschriften DE 102007585 AI sowie DE 102010036924 AI zeigen im Vergleich dazu eine seitlich versetzte Anordnung der Drehfallenachse relativ zum inneren Ende des Einlaufmauls und zwar gesehen entlang des zweiten Hebels von der Seite mit dem außen liegenden Einlaufmaulende aus gesehen. Darüber hinaus sind Drehfallenachse und inneres Einlaufmaul nach wie vor hintereinander im vorgenannten Sinne angeordnet. Die zuvor beschriebenen Merkmale eines Schlosses können einzeln oder in beliebiger Kom bination mit der vorliegenden Erfindung kombiniert werden, soweit nachfolgend nicht ausdrü cklich etwas anderes angegeben wird . The documents DE 102007585 A1 and DE 102010036924 AI show in comparison to a laterally offset arrangement of the rotary latch axis relative to the inner end of the inlet mouth and seen as seen along the second lever from the side with the outer inlet mouth end. In addition, rotary latch axis and inner inlet mouth are still arranged one behind the other in the aforementioned sense. The above-described features of a lock can be combined singly or in any combination with the present invention, unless expressly stated otherwise.
Es ist Aufgabe der vorliegenden Erfindu ng , ein Schloss für ein Kraftfahrzeug mit geringem Kraftaufwand öffnen zu können . It is an object of the present invention to be able to open a lock for a motor vehicle with little effort.
Die Aufgabe der Erfindung wird durch ein Schloss mit den Merkmalen des ersten Anspruchs gelöst. Vorteilhafte Ausführungsformen ergeben sich aus den Unteransprüchen . The object of the invention is achieved by a lock with the features of the first claim. Advantageous embodiments will be apparent from the dependent claims.
Zur Lösung der Aufgabe wird gemäß Anspruch 1 ein Schloss mit einem Gesperre u mfassend eine Drehfalle mit eine m Lastarm und einem Fangarm bereitgestellt, welche auf einer Drehfallenachse drehbar gelagert ist und die einen Schließbolzen aufneh men kann .

I m U nterschied dazu gibt es jedoch Bereiche von Drehfallenachse und innerem Ende des Einlaufmauls, die nebeneinander angeordnet sind . Au ßerdem gibt es vorteilhaft einen Bereich der Drehfallenachse, die vor dem inneren Ende des Einlaufmauls angeordnet ist. Bei dieser letztgenannten Ausführungsform reicht die Achse der Drehfalle in den Fangarmbereich hin ein . To solve the problem, a lock with a locking u comprehensive a catch provided with a m Lastarm and a tentacle, which is rotatably mounted on a rotary latch axis and a lock pin can take men according to claim 1. Seen from the side with the outer end of the inlet mouth along the second lever, the rotary latch axis is displaced laterally in accordance with the prior art known from the documents DE 1 0 2007 585 A1 and DE 1 0 201 0 036 924 A1 arranged next to the inner end of the inlet mouth. In contrast to this, however, there are areas of the rotary catch axis and the inner end of the intake mouth, which are arranged side by side. For putting in there is advantageously a portion of the rotary latch axis, which is arranged in front of the inner end of the inlet mouth. In this latter embodiment, the axis of the catch reaches into the tentacle area.
Es wird so möglich, die Länge des zweiten Hebels nahezu beliebig klein zu di mensionieren , ohne die mechanische Stabilität zu gefährden . Es lassen sich so günstige Sperrteilverhältnisse von beispielsweise wenigstens 4 erzielen, oh ne dafür einen übermäßig großen Bauraum für das Gesperre bereitstellen zu müssen . Unproblematisch ist es möglich, ein Sperrteilverhältnis von fünf und mehr bereitzustellen, um so mit geringer Kraft das Gesperre entrasten zu können. It is thus possible, the length of the second lever almost arbitrarily small to di mensions, without jeopardizing the mechanical stability. It can be so cheap locking part ratios, for example, achieve at least 4, oh ne for it to provide an excessively large space for the locking mechanism. Unproblematic it is possible to provide a blocking division ratio of five and more so as to unlock the locking mechanism with little force.
In einer Ausführungsform der Erfindung befindet sich der Mittelpunkt der Drehfallenachse im vorgenannten Sinn hinter dem inneren Ende des Einlaufmauls der Drehfalle oder auf Höhe des inneren Endes. Es wird so sichergestellt, dass die Länge des zweiten Hebels geeignet von Null verschieden ist, um die Drehfalle mit Hilfe des Schließbolzens in Öffnungsrichtung drehen zu können. In one embodiment of the invention, the center of the rotary latch axis in the aforementioned sense is behind the inner end of the inlet mouth of the rotary latch or at the level of the inner end. It is thus ensured that the length of the second lever is suitably different from zero in order to be able to rotate the catch in the opening direction with the aid of the striker.
Da durch ein günstiges Sperrteilverhältnis von vier, fünf und mehr der auf die Sperrklinke ausgeübte Druck in der Hauptrastposition gering ist, wird diese mechanisch wenig belastet. In einer vorteilhaften Ausführungsform ist es daher möglich, diese aus Kunststoff zu fertigen, ohne die Stabilität des Gesperres zu gefährden. Vorzugsweise besteht die Achse der Sperrklinke jedoch aus Stabilitätsgründen aus Metall. Diese kann jedoch mit geringerem Durchmesser als üblich gefertigt werden. Hierdurch wird Material und Bauraum eingespart. Durch eine Fertigung der Sperrklinke aus Kunststoff wird vorteilhaft das Gewicht und der Herstellungsaufwand verringert. Außerdem wirkt sich eine Fertigung aus Kunststoff vorteilhaft auf eine Geräuschentwicklung aus, da diese reduziert wird und zwar insbesondere ein sogenannter Öffnungsplopp. Wird das Gewicht der Sperrklinke verringert, dann kann eine optional vorgesehene vorgespannte Feder für die Sperrklinke schwächer ausgeführt sein, was mechanische Belastungen vorteilhaft reduziert. Eine optional vorgesehene vorgespannte Feder für die Sperrklinke vermag die Sperrklinke insbesondere in ihre Raststellung hinein zu bewegen. Since a low blocking ratio of four, five and more of the pressure exerted on the pawl pressure in the main detent position is low, it is mechanically stressed little. In an advantageous embodiment, it is therefore possible to manufacture these from plastic, without endangering the stability of the locking mechanism. However, the axis of the pawl is preferably made of metal for stability reasons. However, this can be made with a smaller diameter than usual. As a result, material and space is saved. By manufacturing the pawl made of plastic advantageously the weight and the manufacturing cost is reduced. In addition, a production of plastic has an advantageous effect on a noise, since it is reduced and in particular a so-called Öffnungsplopp. If the weight of the pawl is reduced, then an optionally provided biased spring for the pawl may be made weaker, which advantageously reduces mechanical stress. An optionally provided prestressed spring for the pawl is able to move the pawl into its detent position, in particular.
In einer Ausführungsform der Erfindung verläuft das Einlaufmaul abschnittsweise bogenförmig um die Drehfallenachse herum und zwar insbesondere der Abschnitt, der das innere Ende des Einlaufmauls umfasst. Die Drehachse der Sperrklinke kann dadurch hinreichend entfernt von der Mittelachse des Schlosshalters bzw. des Schließbolzens angeordnet werden. Diese Ausführungsform ermöglicht weiter verbessert eine mechanisch stabile und dennoch kleine Bauform der Drehfalle. Weiter wird ermöglicht, die Drehfalle um weniger als 90° verschwenken zu müssen, um von ihrer Öffnungsstellung in die Hauptrastposition zu gelangen und umgekehrt. Kleine Schwenkbewegungen sind vorteilhaft und zwar unter anderem, um schnell und geräuscharm mit geringem Energieaufwand öffnen und schließen sowie den Bauraum klein halten zu können. Es hat sich weitere herausgestellt, dass durch die Führung des Schließbolzens,, die mit dem bogenförmigen Verlauf einhergeht, die Geräuschentwicklung während des Öffnens oder Schließens reduziert wird. Durch eine solche Führung wird ein Geräuschvorteil erzielt und zwar unabhängig von der Anordnung der Drehachse der Drehfalle. Die Führung stellt daher eine eigenständige technische Lehre dar, mit der Geräusche vorteilhaft reduziert werden können. Eine Führung im Sinne der vorliegenden Erfindung meint einen parallelen Verlauf von zwei sich gegenüberliegenden Begrenzungen, also den entsprechenden sich gegenüberliegenden seitlichen Konturen von Lastarm und Fangarm. Insbesondere ist die Breite einer Führung nur wenig größer als der Durchmesser eines Schließbolzens, um Geräuschvorteile zu erzielen und den Bauraum klein halten zu können. Bereits ab einer Führung, die sich über zumindest 5 mm erstreckt, lassen sich merkliche Geräuschvorteile erzielen. Es hat sich ferner herausgestellt, das in Kombination mit großen Sperrteilverhältnissen die Akustik weiter verbessert werden kann. In one embodiment of the invention, the inlet mouth extends in sections arcuately around the rotary latch axis and in particular the portion which comprises the inner end of the inlet mouth. The axis of rotation of the pawl can thereby sufficiently removed from the central axis of the lock holder and the lock pin to be ordered. This embodiment further enables a mechanically stable, yet small design of the rotary latch. It is also possible to pivot the catch by less than 90 ° in order to move from its open position to the main catch position and vice versa. Small swivel movements are advantageous, among others, to open and close quickly and quietly with low energy consumption and to keep the space small. It has further been found that by the guidance of the locking bolt, which is accompanied by the arcuate course, the noise during opening or closing is reduced. By such a guide, a noise advantage is achieved, regardless of the arrangement of the axis of rotation of the rotary latch. The guide is therefore an independent technical teaching, with the noise can be advantageously reduced. A guide according to the present invention means a parallel course of two opposing boundaries, so the corresponding opposite side contours of load arm and tentacle. In particular, the width of a guide is only slightly larger than the diameter of a locking bolt in order to achieve noise advantages and to be able to keep the installation space small. Starting with a guide that extends over at least 5 mm, noticeable noise advantages can be achieved. It has also been found that in combination with large blocking part ratios the acoustics can be further improved.
In einer Ausführungsform verläuft der Abschnitt des Einlaufmaul, welcher das äußere Ende des Einlaufmauls umfasst, bogenförmig und zwar umgekehrt bogenförmig im Vergleich zu dem in einer Ausführungsform vorgesehenen Abschnitt, der sich bogenförmig um die Drehfallenachse herum erstreckt. Diese Ausführungsform ermöglicht weiter verbessert eine mechanisch stabile und dennoch kleine Bauform der Drehfalle. Weiter wird verbessert ermöglicht, die Drehfalle u m weniger als 90° verschwen ken zu müssen, u m von ihrer Öffnungsstellung in die Hauptrastposition zu gelangen und umge kehrt. In einer Ausführungsform ist das Schloss derart insbesondere in einer Tür eingebaut, dass in der H auptrastposition das innere Ende des Einlauf mauls sich u nterhalb des oberen Endes des Einlauf mauls befindet. Die Achse der Drehfalle liegt dann unterhal b vom Schlosshalter in der Hauptrastposition, wenn das Schloss in einer Tür eingebaut ist. Es wird bei dieser Ausführungsform vermieden, dass aufgru nd des Türgewichts eine Kraft auf die Sperrklinke übertragen wird , was nachteilhaft zu mecha nischen Belastungen führen würde. Außerdem wird die Gefahr einer Versch mutzung verringert. Nachfolgend wird die Erfindung anhand einer in einer Figur dargestellten vorteilhaften Ausführungsform nä her erläutert. In one embodiment, the portion of the lead-in mouth that includes the outer end of the lead-in mouth is arc-shaped, and vice versa, arcuate in comparison to the portion provided in one embodiment that extends arcuately about the rotary-disc axis. This embodiment further enables a mechanically stable, yet small design of the rotary latch. Further is improved allows the catch to less than 90 ° verschwen ken to get from its open position to the main detent position and vice versa. In one embodiment, the lock is installed in such a way in particular in a door, that in the H auptrastposition the inner end of the inlet mouth is located m u nterhalb the upper end of the enema. The axis of the catch is then unterhal b from the lock holder in the main latch position when the lock is installed in a door. It is avoided in this embodiment that aufgru nd the door weight, a force is transmitted to the pawl, which would disadvantageously lead to mechanical loads African. In addition, the risk of contamination is reduced. The invention will be explained with reference to an advantageous embodiment shown in a figure nä ago.
Die Sperrklinke kann für ein Verrosten der Drehfalle a m Lastarm oder a m Fangarm verrosten. The pawl can rust for rusting the catch a m Lastarm or a m Fangarm.
Das a u ßen liegende Ende des Einlauf mauls der Drehfalle kann im eingebauten Zusta nd oberhal b des in nen liegenden End es liegen oder beispielsweise auch unterhalb. I nsbesondere wird dieser Ausrichtung auf den zur Verfügung stehenden Baurau m abgestim mt. The outer end of the inlet mouth of the rotary latch can lie in the installed state above the inside end or, for example, below it. In particular, this alignment is tailored to the available construction space.
Das Sperrteilverhältnis des erfi ndungsgemäßen Gegenstandes liegt bevorzugt oberhalb von drei, besonders bevorzugt oberhalb von fünf. Es hat sich herausgestellt, dass mit der vorliegenden Erfind ung insbesondere Sperrteilverhältnisse von 5,5 bis 6,5 in praktikabler Weise verwirklicht werden können . Sperrteilverhältnisse von bis zu 7 sind in der Regel möglich. Sperrteilverhältnisse von mehr als 7 können zwar auch realisiert werden, führen aber gru ndsätzlich zu unerwünscht großen Bau ra umvergrößerungen . The blocking part ratio of the object according to the invention is preferably above three, more preferably above five. It has been found that with the present invention in particular blocking sub-ratios of 5.5 to 6.5 can be implemented in a practical manner. Barrier ratios of up to 7 are usually possible. Blocking ratios of more than 7 can indeed be realized, but in principle result in undesirably large construction space enlargements.
Durch große Sperrteilverhältnisse kann insbesondere vorteilhaft eine Zuzieh hilfe mit gerin ger Leistung eingesetzt werden . By large blocking sub-conditions can be used in particular advantageous Zuzieh help with clotting ger performance.
Der Schlosshalter wird bevorzugt durch eine Klammer gehalten. The lock holder is preferably held by a clamp.
Figur 1 zeigt Gesperre in der Hauptrastposition . FIG. 1 shows ratchets in the main ratchet position.
Die Fig ur 1 zeigt eine Drehfalle 1 , die durch eine Sperrklinke 2 verrastet ist. Die Drehfalle umfasst einen Fangarm 3 u nd einen Lastarm 4, d urch die ein Einlaufschlitz 5 gebildet wird . Der Ein laufschlitz 5 hält einen Schlosshalter bzw. Schließbolzen 6. Zu m Beispiel a ufgrund eines Türdichtungsdrucks wird der Schlosshalter 6 mit einer Kraft F in Richtung des dargestellten Pfeils gezogen . Der Lastarm 4 verhi ndert jedoch, dass der Schlosshalter 6 du rch die Kraft F aus dem Gesperre heraus bewegt wird . Die Drehfalle 1 ist d urch eine Achse 7 drehbar gelagert. Diese Achse 7 der Drehfalle 1 reicht teilweise in den Bereich des Fangarms 3 hinein und befindet sich daher bereichsweise neben oder vor dem inneren Ende 8 des Einlaufma uls 5 und zwar gesehen entlang einer zum Kraftpfeil F sen krechten Richtung sowie vom äußeren Ende 9 des Einlaufmauls 5 aus gesehen . 1 shows a rotary latch 1 which is locked by a pawl 2. The rotary latch comprises a catching arm 3 and a load arm 4, by means of which an inlet slot 5 is formed. A running slot 5 holds a lock holder or locking pin 6. For example, due to a door seal pressure, the lock holder 6 is pulled with a force F in the direction of the arrow shown. However, the load arm 4 prevents the lock holder 6 from being moved out of the ratchet by the force F. The rotary latch 1 is rotatably supported by an axle 7. This axis 7 of the catch 1 extends partially into the region of the tentacle 3 and is therefore partially adjacent or in front of the inner end 8 of the Einlaufma uls 5 and seen along a direction of the force arrow F sen direction and from the outer end 9 of the inlet mouth. 5 seen from.
Die i n der Figur 1 gezeigte Ausrichtu ng der Drehfal le 1 entspricht dem in einer Tür eingebauten Zustand, so dass das außen liegende Ende 9 des Einlaufma uls 5 oberhalb des innen liegenden Endes 8 liegt. The orientation shown in FIG. 1 of the rotary latch 1 corresponds to the state installed in a door, so that the outer end 9 of the inlet sleeve 5 lies above the inner end 8.
In der Figur 1 wird ein Anschlag 1 0 gezeigt, d urch den eine übermäßige Schwenkbeweg ung der Drehfalle 1 entgegengesetzt zum Uhrzeigersinn und damit ausgehe nd von der Öffnungsstellung der Drehfalle 1 in Richtung Schließstellu ng verhindert wird. In the figure 1, a stop 1 0 is shown, d urch by the excessive Schwenkbeweg ung the rotary latch 1 opposite to the clockwise direction and thus out of the open position of the rotary latch 1 in the direction of Schließstellu ng is prevented.
Wird die Sperrklin ke 2 um ihre Achse 1 1 herum im U hrzeigersinn gedreht, so verlässt diese ihre Rastposition . Die Drehfalle 1 kann anschließend im Uhrzeigersin n in Richtung Öffnu ngsstellung gedreht bzw. geschwenkt werden . Hat die Drehfalle 1 ihre Öff n ungsstellung erreicht, so kann der Schlosshalter 6 das Gesperre verlassen . Der Anschlag 1 0 begrenzt auch diese Schwenk- bzw. Drehbewegung der Drehfalle 1 im Uhrzeigersin n, also ein Drehen für ein Öffnen des Gesperres. If the Sperrklin ke 2 is rotated around its axis 1 1 clockwise around, so she leaves her detent position. The catch 1 can then be rotated or pivoted in the clockwise direction n in the direction of opening. If the catch 1 has reached its opening position, the lock holder 6 can leave the locking mechanism. The stop 1 0 also limits this pivoting or rotational movement of the rotary latch 1 in the clockwise direction n, that is, a rotation for opening the locking mechanism.
Durch die Anordnung eines Bereichs der Ac hse 7 neben dem inneren Ende 8 des Ei nlaufmauls 5 ka n n ein in zum Kraftpfeil F senkrechter Richtung sehr geringer Abstand a zwischen Mittelpunkt der Drehfalle nachse u nd Kontaktbereich zwisc hen Schlosshalter 6 und Lastarm 4 bereitgestellt werden . Der dadurch bereitgestellte kleine zweite Hebel a beginnt beim Mittelpunkt der Drehfallenachse 7, mündet in der gezeigten Hauptrastposition senkrecht in den Kraftpfeil F ein und endet hier. I n der Figur 1 wird der Fall gezeigt, dass sich der Mittelpunkt der Drehfallenachse auf Höhe des i nnere n Endes 8 des Einlaufmauls liegt, wie dies durch eine eingezeichnete Linie verdeutlicht wird . By arranging a portion of the Ac hse 7 next to the inner end 8 of the egg nlaufmauls 5 ka n n in a direction perpendicular to the force F direction very small distance a between the center of the catch nachse u nd contact area between hen lock holder 6 and load arm 4 are provided. The thus provided small second lever a begins at the center of the rotary latch axis 7, opens in the main locking position shown perpendicular to the force arrow F and ends here. In the figure 1, the case is shown that the center of the rotary latch axis is located at the level of i nnere n end 8 of the inlet mouth, as is illustrated by a line drawn.
Der Abstand der Achse 7 zum i n neren Ende 8 ist ähnlich groß wie der Absta nd der Drehfallenachse 7 zum links gezeigte n Rand der Drehfalle bzw. des Fangarms 3. Die Achse 7 ist also zu mindest näherungsweise mittig zwischen dem inneren Ende 8 des Ei nlaufmauls 5 u nd dem gegenüberliegenden, äußeren Rand des Fangarms angeord net. Hierd urch wird die mechanisc he Stabilität und Belastbarkeit des Fangarms mit optimiertem Materialeinsatz gewährleistet. The distance between the axis 7 to neren end 8 is similar to the Absta nd the rotary latch axis 7 to the left shown n edge of the rotary latch or the tentacle 3. The axis 7 is thus at least approximately centrally between the inner end 8 of the egg jaw mouth 5 and the opposite, outer edge of the tentacle angeord net. This ensures the mechanical stability and load capacity of the tentacle with optimized material usage.
Um den Materialeinsatz weiter verbessert zu optimieren, ist der Fa ngarm 3 wie dargestellt auf Höhe des inneren Endes, bei der Drehfallenachse 7 breiter ausgeführt als der Lastarm 4. Vorzugsweise ist der Fangarm in diesem Bereich 1 ,5 bis 2,5 mal so breit wie der Lastarm 4. Bei den freien Enden angrenzend an das offene, äußere Ende 9 des Einlaufmauls 5 sind Fangarm und Lastarm jedoch wie dargestellt vorteilh aft ä hnlich breit, um den Materialeinsatz und damit Gewicht und Bauraum zu minimieren. Die Breite des Fangarms 3 entspricht hier der Breite des Lastarms 4. In order to optimize the use of materials further improved, the Fa ngarm 3 is as shown at the level of the inner end, in the rotary latch axis. 7 Preferably, the tentacle is in this area 1, 5 to 2.5 times as wide as the load arm 4. At the free ends adjacent to the open, outer end 9 of the inlet mouth 5 tentacle and load arm, however, are like shown advantageous aft ä similar wide to minimize the use of materials and thus weight and space. The width of the tentacle 3 here corresponds to the width of the load arm. 4
Der erste Hebel erstreckt sich entsprechend des dargestellten Abstands 5a, so dass das in der Figur 1 gezeigte Gesperre ein Sperrteilverhältnis von 5 aufweist. The first lever extends in accordance with the illustrated distance 5a, so that the locking mechanism shown in FIG. 1 has a locking part ratio of 5.
Das Einlaufmaul 5 verläuft ausge hend vom inneren Ende 8 zunächst bogenförmig um die Drehfallenachse 7 herum und zwar in etwa bis zur Hälfte der Gesa mtlänge des Einlaufmauls 5. Der sich daran anschließende Abschnitt des Einlaufmauls verläuft umgeke hrt bogenförmig bis in etwa zum außen liegenden Ende 9 d es Einlaufmauls. Dieser Verlauf leistet einen Beitrag für einen optimierten Materialeinsatz, mit dem die mechanische Stabilität erreicht werden kan n . Durch diese bogenförmigen Verläufe, die durch parallel verlaufende seitliche Begrenzungen bzw. Konturen von Lastarm 4 und Fa ngarm 3 gebildet sind , wird d er Schließbolzen 6 über mehr als 5 mm geführt. Durch eine solche Führun g lassen sich merkliche Geräuschvorteile erzielen . The inlet mouth 5 extends from the inner end 8 initially arcuately around the rotary latch axis 7 around and in about half of the Gesa mtlänge of the inlet mouth 5. The adjoining portion of the inlet mouth runs umgeke hrt arcuate to approximately the outer end. 9 the inlet mouth. This course contributes to optimized material use, with which the mechanical stability can be achieved. Through these arcuate courses, which are formed by parallel lateral boundaries or contours of load arm 4 and Fa ngarm 3, d the locking pin 6 is guided over more than 5 mm. Such guidance can provide appreciable noise benefits.
