Definitions
- the invention relates to a lock for a motor vehicle having the features of the preamble of claim 1.
- An initially mentioned lock comprises at least one usually made of metal lock plate (also called lock case) with a mounted thereon locking mechanism.
- the lock plate is usually provided with an inlet slot for receiving a locking bolt.
- the locking mechanism comprises a rotatably mounted rotary latch for receiving a locking bolt.
- the locking mechanism further has a pawl with which the catch can be locked.
- the catch of a motor vehicle lock usually has a bifurcated inlet slot formed by load arm and catching arm into which the locking bolt of a vehicle door or flap, for example bonnet or trunk lid, comes when the door or flap is closed.
- the locking pin then rotates the catch from an open position to a closed position. If the catch has reached a corresponding closed position, it is locked in this position via the pawl.
- the locking bolt can not leave the inlet slot of the rotary latch.
- This detent position is called main detent position or main detent position.
- pre-detent position serves to intercept the corresponding door or flap if it does not reach the main detent position when closing.
- the rotary latch in the pre-locking position, the rotary latch is not completely closed, but an opening movement of the rotary latch is already prevented by a pawl. That is why the area of Rotary latch, which receives the pawl in this position, referred to as a pre-detent.
- the pre-restraint thus represents a transition state between the opened state and the main rest and is provided for safety reasons.
- the locking pin exerts a corresponding pressure on the load arm. Since the load arm is connected to the rotary latch axis, a corresponding force is transmitted to the rotary latch axis.
- the stress can also affect the pawl. In a conventional lock, therefore, the individual parts of a locking mechanism are built so stable that they can cope not only with the daily operation, but also sudden impact stresses.
- the object is achieved by providing a lock with a lock case and a locking mechanism comprising a rotary latch with a load arm and a catch arm, which is rotatably mounted by means of a rotary latch axis.
- the catch can take a locking pin.
- the locking mechanism has a pawl for locking the catch.
- a pivotable power transmission latch is provided, with which a transmitted by a locking pin on the load arm force can be routed out of the locking mechanism and transmitted to the lock case, for example.
- the pivotable power transmission bolt is arranged in particular so that, in particular, the rotary latch axle is relieved.
- the power transmission bolt is therefore basically on the side of the inlet slot of the lock box on which the rotary latch axis is located.
- the power transmission bolt is in the open position of the lock or the locking mechanism in a rest position. Rest position means that then the power transmission bolt is unable to conduct forces out of the locking mechanism and transfer it to another component such as the lock case. It is further provided that the power transmission bolt is pivoted in the main locking position of the locking mechanism in such a position that the power transmission bolt is able to derive excessive forces from the locking mechanism. This situation is called "power transmission position" below.
- the necessary pivotal movements of the power transmission bar can be realized by springs or other mechanical solutions or electronically or magnetically triggered and / or controlled.
- a power transmission bolt of a motor vehicle lock is already in the non-prepublished German patent application with the official file number 10 2009 029 025.7 described. All features and designs of this German Patent application known lock may in principle also include the claimed with this patent application lock.
- the now claimed lock differs from that of the German patent application with the official file number 10 2009 029 025.7 However, known lock with respect to the rest position of the power transmission bolt. In the rest position, the power transmission bolt is in contrast to that from the German patent application with the official file number 10 2009 029 025.7 known teaching outside the plane in which the catch is rotated, ie above or below the catch to allow a particularly space-saving design.
- the use of the pivotable power transmission bolt to transmit excessive forces, such as may occur in a crash, from the ratchet on, for example, the lock box allows the interpretation of the locking mechanism on the forces occurring in daily use while the presence of emergency reserves for emergency (crash), since the forces are then transferred to the lock case or another external component and not alone on the catch, the rotary latch axis and possibly the pawl.
- the cost of materials for the lock can be reduced as a whole.
- An inventive lock can therefore be advantageous overall small and built with less weight.
- the power transmission bolt is preferably pivotally mounted such that the catch is able to pivot the power transmission bolt away from its power transmission position by a rotational movement from a closed position to the open position. If the power transmission bolt has been pivoted away in this way, then in one embodiment of the power transmission bolt is above or below the Lastarms of the catch and seen from the base of the lock plate, which basically has the inlet slot for the locking pin. In particular, is located the power transmission bolt then below the catch and thus below the load arm, because then the pivot or rotation axis of the power transmission bolt can be attached to the base of the lock plate and this is no additional component to provide. This represents a particularly simple, more space-saving design.
- the axis of rotation of the power transmission latch preferably extends at least substantially parallel to the inlet slot of the latch box.
- the power transmission bolt is pivotally mounted so that the catch is able to pivot the power transmission bolt away from its power transmission position as described above, there is advantageously a biased spring element capable of pivoting the power transmission bolt back into its power transmission position.
- the power transmission bolt is moved in this embodiment by the spring in its power transmission position when the catch is rotated from its open position towards the closed position and therefore releases the power transmission bolt.
- a substantially metal existing load arm which may have a sheath made of plastic, a nose made of plastic, which against the Power transmission bar abuts and pivots this when the catch is rotated from a latched position to the open position. Opening noises are minimized.
- microswitch actuated by the pivoting of the power transmission bar.
- the microswitch is used for control purposes, such as turning on interior lighting of the vehicle when the catch is not in the main latching position.
- the micro-switch can also be used to activate a warning signal when the power transmission latch is not pivoted into its power transmission position, even though the catch has reached its main detent position. This embodiment makes it possible to easily display a fault.
- a microswitch and other detector means can be used, which are able to signal a pivoting of the power transmission bar in a selected position.
- a detector means may for example be a proximity sensor capable of signaling an approach of the power transmission bar or a part of the power transmission bar.
- the power transmission latch is connected to a lever arm with which a microswitch or other detection means is actuated or triggered when the power transmission latch is pivoted.
- the lever arm is arranged so that it is pivoted through an opening of the lock plate, when the power transmission bolt is pivoted to its rest position.
- a microswitch or other detector means actuated or triggered by the lever arm may then advantageously be arranged on the side of the lock plate opposite the ratchet. The lock plate then separates so the locking of electrical or electronic components that are able to signal the position of the power transmission bolt.
- the lock comprises a lever capable of acting on the power transmission latch, hereinafter referred to as "control lever".
- the control lever comprises a first lever arm which is moved starting from a starting position, in particular by the locking pin, when the rotary latch is rotated by the locking bolt in the direction of the main locking position.
- the control lever comprises a second lever arm. If the first lever arm is moved together with the rotary latch in the direction of the main latching position, then the second lever arm can detect and move the pivotable power transmission latch so that the power transmission latch is pivoted into its power transmission position. Alternatively or additionally, the second lever arm reaches such a position that, in the main locking position of the locking mechanism of the power transmission bolt, it is prevented by the second lever arm from pivoting back into its rest position. The reliability of the lock is improved.
- the control lever which is capable of acting on the power transmission latch, includes means for moving the control lever to its home position when the latch is opened.
- Such means may be a spring which moves the power transmission latch to its home position when the latch is released or the lock is opened.
- This means may alternatively or additionally comprise a third lever arm, which is preferably moved by the locking pin when the locking mechanism is released and the locking pin is moved out of the locking mechanism.
- the second lever arm is prevented from moving by the power transmission latch when, for example, the power transmission latch can not be pivoted into the power transmission position by a spring or a correspondingly acting means due to damage. A door or flap can then no longer be properly closed. A corresponding damage does not go unnoticed in this embodiment.
- the catch comprises a main catch and a pre-ratchet.
- the first lever arm of the control lever is then preferably dimensioned and is thus rotated together with the catch during a closing operation, that a pawl initially can not lock into the pre-catch. It is the closing process otherwise occurring noise from the non-prepublished German patent application with the official file number 10 2008 046 931.9 avoided mentioned reasons.
- the corresponding lever is referred to in this German patent application as Vorrastunterdschreibungshebel.
- the known advantageous embodiments of the Vorrastunterdschreibungshebels known therefrom can in principle also be embodiments of the now claimed lock.
- the control lever is thus in one embodiment, at the same time a Vorrastunterdschreibungshebel.
- a pawl of the locking mechanism in the main latching position prevents the control lever from being able to reach its starting position, from which the control lever is able to move the power transmission latch into its power transmission position.
- the control lever can only be pivoted or rotated to its initial position when the pawl is pivoted away.
- the pawl which locks the catch in the main latching position, at the same time the pawl, which prevents the control lever from being turned back or pivoted in the main latching position to its initial position.
- a preloaded compression spring which is able to move the control lever in its two end positions.
- the second lever arm of the control lever presses against the power transmission bolt and thus contributes to the fact that the power transmission bolt is reliably held in its power transmission position.
- the other end position is the aforementioned starting position.
- the control lever is, for example, in its initial position and this is rotated by means of a locking pin in the direction of its other end position, the lever reaches a reversal point, from which the biased compression spring pushes the control lever in its other end position.
- control lever If the control lever is in its other end position and the control lever is rotated, for example, by means of a locking bolt in the direction of its initial position, the lever in turn reaches said reversal point, from which the prestressed compression spring then pushes the control lever into its initial position.
- the control lever is always moved completely into its respective end position and does not move out of such an end position unscheduled out. This will be the Operational safety of the locking further improved.
- the control lever is also designed as Vorrastunterd Wegungshebel, so it is ensured that the control lever during the closing of an associated vehicle door or vehicle door can not be unintentionally turned back together with the catch in the open position when the main detent position is not reached. The possibility of latching in the pre-locking position is thus improved.
- the rotary latch comprises a stop for the control lever.
- This stop is arranged so that it can additionally ensure that the control lever is moved in the direction of the starting position when the locking mechanism is unlatched. This embodiment ensures that the control lever can be moved back to its initial position even if the locking mechanism has been latched without a locking pin in the inlet slot.
- the lock is designed so that a pivoting of the power transmission latch in its rest position detects the control lever and moves in the direction of the starting position.
- This embodiment provides as an alternative or in addition to the aforementioned embodiment, that the control lever can be moved back to its initial position even if the locking mechanism has been locked without a locking pin is in the inlet slot.
- control lever there is a stop for the control lever.
- the control lever reaches this stop when it has been fully moved into its home position.
- the control lever is advantageously made of plastic to keep the weight of the lock low.
- control lever which acts on the power transmission bar, is also advantageous when the power transmission bar as described can be pivoted back and forth between two positions for the reasons mentioned above, but the rest position of the power transmission bar is not outside the plane within which the catch can be turned.
- the control lever can therefore be the subject of an independent invention, which does not comprise all the features of claim 1.
- the lock case or the lock plate is preferably constructed in two parts.
- the lock case comprises a metallic plate on which the catch and the pawl are rotatably mounted.
- the locking mechanism comprises a control lever, it is preferably also rotatably mounted on the metallic plate.
- the lock case is made of plastic to minimize the weight of the lock.
- the plastic part of the lock case is preferably fixedly connected to the metallic plate, for example by means of a screw, rivet and / or adhesive connection. Should it be expedient for reasons of stability, for example, then the lock case is made entirely of metal.
- the metallic plate of the lock case preferably extends angularly around the inlet slot of the lock case. At one end of the angle, the pawl of the locking mechanism is rotatably mounted and at the other end the catch. The metallic part of the lock case and thus its weight are minimized.
- Lock box width means the extent of the lock case along the inlet slot of the lock case. What is meant by lock case width is also clear from the embodiments described below.
- the pivotable power transmission bolt is in particular attached to the lock case and / or arranged so that it extends from a side wall of the lock case in the main latching position to the catch. This lateral wall adjoins the lock box entry slot for the lock bolt at a right angle.
- the power transmission bolt is arranged in particular adjacent to the inlet slot of the lock case, and preferably on the side of the inlet slot on which the rotary latch axis is arranged. In the main locking position, the power transmission bolt then adjoins the rotary latch in such a manner that the rotary latch is pressed against the power transmission bolt in the case of the abrupt stresses described. The power transmission bolt then absorbs the corresponding force and forwards it to the lock case, and indeed because of its attachment and / or due to its support on a corresponding side lock case wall.
- the power transmission bolt may be wholly or partly made of metal and of the same or a different material as the Be made catch.
- the power transmission bolt is made of plastic and in particular if it is supported on a corresponding side lock case wall.
- the power transmission bar is then on the one hand relatively light and on the other hand can be constructed stably enough to cope with the described requirements.
- the power transmission bolt in the installed state of the lock can always also be supported on a wall of the vehicle in order to transfer forces from the locking mechanism to other components in the main latching position, for example into a vehicle door or vehicle door.
- the power transmission bolt is preferably arranged within the lock case. Particularly preferably, it is arranged in spatial proximity to the rotary latch axis, very particularly preferably in spatial proximity to the load arm, in particular in spatial proximity to the load arm and the rotary latch axis. Such arranged power transmission bar basically requires no additional space.
- the power transmission bar touches the catch, preferably the load arm of the catch only when due to strong forces, the catch is moved in the main latching position in the direction of power transmission bolt. It is thus advantageously avoided the occurrence of frictional forces during normal operation due to a regular contact between the rotary latch and power transmission.
- the distance between the power transmission bolt and the rotary latch is chosen so small that the rotary latch axle can not be deformed so that it breaks before the catch is supported by the power transmission bar.
- the power transmission bolt is preferably cuboid, since the available space can then be used optimally. But there are also other Krafttragungsriegelgeometrien, such as Example rod-shaped or crescent-shaped embodiments used.
- the power transmission bolt is in the main detent position of the rotary latch in spatial proximity to the load arm, particularly preferably the power transmission latch enters a bulge of the load arm so as to maintain its position particularly reliably when high forces are transmitted from the rotary latch to the latter.
- Either the power transmission bolt can be particularly firmly anchored to a lock case wall on which it is for example mounted movably, for example by a guide or rivet and / or it can touch both the load arm and at least one lateral lock case wall in the main load position of the catch at high load ,
- the catch completely or partially made of metal.
- metal in the context of the invention here preferably steel, hardened steel or a steel alloy is used.
- at least the load arm is preferably made of metal or reinforced with metal.
- the metal in the invention are preferably steel, hardened steel and steel alloys for use.
- the catch can be completely or partially encased in plastic. Individual components of the rotary latch, in particular the catch arm, which is comparatively slightly loaded even in crash situations, can be used partially or completely made of plastic, to make the lock easy and inexpensive.
- the pawl may be formed of metal or plastic. Preferably, however, it is made of metal.
- both the pre-rest and the main rest is performed on the load.
- This allows a construction of the tentacle with low weight and contributes to the weight reduction and compactness of the overall construction.
- the locking positions are preferably formed entirely or partially of metal.
- the narrowest point of the load arm of the catch is preferably wider than the widest point of the catching arm, since above all the load arm is loaded.
- the installation space for a lock can be further reduced.
- the lock comprises a locking pin which has a cross-section in the form of a flattened circle in the sense of the non-prepublished German patent application with the official file number 10 2009 029 034.6 has, wherein the flattened portion of the circle rests in the main latching position on the rotary latch in the direction of the rotary latch axis, so as to be able to open a lock particularly easily.
- the known therefrom embodiments of a castle, in order to open such with little effort, may also include the presently claimed lock.
- the region of the rotary latch which encloses the rotary latch axis is preferably at least partially made of metal for reasons of stability.
- enclosing a metallic portion of the catch the rotary latch axis only partially and that in the non-prepublished German patent application with the official file number 10 2009 029 014.1 known way.
- the known therefrom embodiments of a castle, in order to open such with little effort, may also include the presently claimed lock.
- the metallic region of the rotary latch, which surrounds the rotary latch axis, is thus opened in the direction of the inlet slot of the rotary latch.
- the locking part ratio of the locking mechanism in one embodiment is equal to or greater than 3 in order to open the lock with little effort.
- Such a large blocking part ratio can be particularly easily by the German patent applications with the official file number 10 2009 029 014.1 such as 10 2009 029 034.6 achieve known embodiments, as already disclosed in these two patent applications.
- the lock according to the invention is outstandingly suitable for use in motor vehicles. It is easier and less expensive compared to traditional locks.
- FIG. 1 an embodiment of a locking mechanism with a catch comprising a wholly or predominantly made of metal load arm 1 and a wholly or predominantly made of plastic tentacle 2 and a pawl 3 is shown in the main latching position.
- the pawl 3 is pressed by a prestressed spring 4 in the direction of detent position and indeed in the main catch 1 b of the catch inside.
- the one spring arm 5 is supported for this purpose, as shown on a side lock case wall 6.
- the other spring arm 7 presses laterally against an upwardly projecting projection 8 of the lever arm 21 of the pawl 3, with which the catch has been locked.
- the pawl 3 is made with the exception of a sheath and the projection 8 made of metal.
- the projection 8 is fixed by means of the jacket on the pawl 3. Projection 8 and sheathing are made of plastic.
- the catch also includes a pre-rest 1a.
- the pawl can lock the catch, for example, when an associated door or flap was closed with insufficient speed or force, and the catch has therefore not reached the main detent position.
- An Indian FIG. 1 Unillustrated locking pin is prevented by the load arm 2 in the illustrated main detent position from leaving the inlet slot 9 of the lock case on which the catch and the pawl 3 are rotatably mounted.
- the locking pin can then press accordingly against the load arm 1 of the catch, but not against the tentacle 2 due to such forces.
- the load arm 1 therefore absorbs such a force.
- An existing plastic force transmission bolt 10 is positioned so that such excessive force in the Power transmission 10 is initiated. Since the power transmission bolt 10 is supported against the side lock case wall 6, the force is introduced into the lock case via this power transmission bar 10.
- the lateral lock case wall 6 is integrally connected perpendicularly to the wall 11 of the lock case, on which, inter alia, as shown, the metal axle 12 of the pawl 3 is fixed.
- axis 13 On the power transmission bolt 10 is an integrally connected thereto axis 13 is arranged.
- the power transmission bar 10 can be rotated about this axis 13 around between two end positions back and forth.
- end position In the in the FIG. 1 shown end position is the power transmission bar 10 in the power transmission position. Turning beyond this end position is prevented by a stop 11 a, which is provided in the form of a curvature through the wall 11 of the lock case.
- One end of the axle 13 of the transmission rod 10 is looped by a prestressed spring 14.
- the spring arms of the spring 14 are supported in a manner not shown that the spring 14 presses the power transmission bolt 10 in the direction of power transmission position.
- lever arm 15 From the axis 13 of the transmission rod 10 is an integrally connected thereto lever arm 15 from the side. With the help of this lever one or more micro-switches, not shown, or other detector means can be actuated or triggered, which are able to inform about the position of the lever arm 15 and thus the position of the power transmission rod 10.
- the lock shown comprises a completely made of plastic, rotatably mounted on the lock plate control lever, which is able to act on the power transmission bar 10.
- This control lever initially acts as Vorrastunterd Wegungshebel.
- the associated metal rotary axis 24 is at the same time also the axis of rotation of the rotary latch.
- the control lever is located above the rotary latch.
- This control lever comprises a first lever arm 16, which is moved by the locking pin when the locking mechanism is latched by the locking pin.
- the control lever includes a second lever arm 17.
- the first lever arm 16 is moved by the latch bolt, the second lever arm 17 may engage and move the pivotal power transmission latch 10 to pivot the power transmission latch 10 into its power transmission position.
- main locking position blocked the second lever arm 17, the power transmission bar 10 so that the power transmission bar 10 can not be pivoted out of its power transmission position.
- the Indian FIG. 1 shown lock case is only 5.5 cm wide.
- the distance between the lock case wall 6 and the opposite lock case wall 25 is therefore only 5.5 cm.
- the control lever which is able to act on the power transmission bar 10, comprises a third lever arm 18, by means of which the control lever can be moved in the direction of its initial position.
- the third lever arm 18 is engaged by the striker when the catch is unlatched and the striker is moved out of the ratchet. As a result, the control lever is moved into its starting position.
- the control lever or the pre-detent suppression lever will not immediately also turn back, since the striker will only detect the third lever arm after a delay. Because of this difference in movement, the first lever arm 16 then releases the lateral area of the rotary latch with the pre-rest 1a underneath, so that the lever arm 21 of the locking pawl 3 can now latch into the pre-locking position.
- the projection 8 of the pawl 3 prevents in the main latching position the control lever to get to its starting position. Should the control lever unintentionally want to rotate to its original position, then the end of the first lever arm 16 abuts against the projection 8, which prevents the continuation of the rotational movement. The control lever can thus be pivoted or rotated only in its initial position when the pawl 3 has been pivoted out of the detent position.
- the catch is provided with a protruding from the load arm 2 from above, consisting of plastic stop 19.
- the stop 19 is placed so that against this stop the first lever arm 16 and the second lever arm 17 can strike, but not the third lever arm 18.
- the stopper 19 is thus in principle suitable for moving the control lever or to hold it in certain positions.
- the lock shown comprises a stop 20 made of elastic material such as rubber for the catch and the control lever, which is fastened to the lock plate.
- This stop limits the rotational movements of the rotary latch and lever arm.
- a special feature of this stop 20 is that this is able to limit the rotational movements of the catch and / or the control lever in both directions of rotation. So only one component is needed, which is able to reduce the manufacturing cost. Due to the elastic properties of the stop 20 noise developments are minimized.
- the pawl 3 comprises two metal lever arms 21 and 22.
- the one lever arm 21 is used to lock the catch.
- the other lever arm 22 is detected and moved when the ratchet is to be unlocked.
- the lock shown also includes a spring 23, which presses the catch in the direction of the open position.
- FIG. 2 clarifies that includes in the FIG. 1
- the lock also shown a metal plate 26 (further lock plate), which extends from the axis 12 of the rotary latch 3 to the lock box inlet slot 9 around to the axis 24 of the rotary latch or the control lever, which is also a Vorrastunterdschreibungshebel.
- the plate 26 is located from the lock plate wall 11 as seen above the Vorrastunterdschreibungshebels and above the pawl 3.
- the two axes 12 and 24 open into the plate 26, which thereby contributes to the stability of Gesperres without having to operate excessive material costs.
- FIG. 3 shows a modified embodiment of the invention.

Description
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
Ein eingangs genanntes Schloss umfasst zumindest eine in der Regel aus Metall bestehende Schlossplatte (auch Schlosskasten genannt) mit einem darauf gelagertem Gesperre. Die Schlossplatte ist in der Regel mit einem Einlaufschlitz für die Aufnahme eines Schließbolzens versehen. Das Gesperre umfasst eine drehbar gelagerte Drehfalle für die Aufnahme eines Schließbolzens. Das Gesperre weist weiter eine Sperrklinke auf, mit der die Drehfalle verrastet werden kann.An initially mentioned lock comprises at least one usually made of metal lock plate (also called lock case) with a mounted thereon locking mechanism. The lock plate is usually provided with an inlet slot for receiving a locking bolt. The locking mechanism comprises a rotatably mounted rotary latch for receiving a locking bolt. The locking mechanism further has a pawl with which the catch can be locked.
Die Drehfalle eines Kraftfahrzeugschlosses verfügt üblicherweise über einen durch Lastarm und Fangarm gebildeten gabelförmigen Einlaufschlitz, in den der Schließbolzen einer Fahrzeugtür oder Klappe, beispielsweise Motorhaube oder Kofferraumklappe, gelangt, wenn die Tür bzw. Klappe geschlossen wird. Der Schließbolzen verdreht dann die Drehfalle von einer Öffnungsstellung in eine Schließstellung. Hat die Drehfalle eine entsprechende Schließstellung erreicht, so wird sie in dieser Position über die Sperrklinke verrastet. Der Schließbolzen kann den Einlaufschlitz der Drehfalle nicht mehr verlassen. Diese Raststellung wird Hauptrastposition oder Hauptraststellung genannt.The catch of a motor vehicle lock usually has a bifurcated inlet slot formed by load arm and catching arm into which the locking bolt of a vehicle door or flap, for example bonnet or trunk lid, comes when the door or flap is closed. The locking pin then rotates the catch from an open position to a closed position. If the catch has reached a corresponding closed position, it is locked in this position via the pawl. The locking bolt can not leave the inlet slot of the rotary latch. This detent position is called main detent position or main detent position.
Es gibt Kraftfahrzeugschlösser mit einer zweiten Rastposition, nämlich die so genannte Vorrastposition bzw. Vorraststellung, Die Vorrastposition dient dazu, die entsprechende Tür oder Klappe abzufangen, wenn diese beim Schließen die Hauptrastposition nicht erreicht.There are motor vehicle locks with a second detent position, namely the so-called pre-detent position or pre-detent position. The pre-detent position serves to intercept the corresponding door or flap if it does not reach the main detent position when closing.
In der Vorrastposition ist die Drehfalle folglich nicht vollständig geschlossen, jedoch wird eine Öffnungsbewegung der Drehfalle durch eine Sperrklinke bereits verhindert. Darum wird auch der Bereich der Drehfalle, der die Sperrklinke in dieser Position aufnimmt, als Vorrast bezeichnet. Die Vorrast stellt also einen Übergangszustand zwischen geöffnetem Zustand und Hauptrast dar und wird aus Sicherheitsgründen vorgesehen.Consequently, in the pre-locking position, the rotary latch is not completely closed, but an opening movement of the rotary latch is already prevented by a pawl. That is why the area of Rotary latch, which receives the pawl in this position, referred to as a pre-detent. The pre-restraint thus represents a transition state between the opened state and the main rest and is provided for safety reasons.
Der Druckschrift
Führt ein Crash dazu, dass sich eine Tür zu öffnen versucht, so übt der Schließbolzen einen entsprechenden Druck auf den Lastarm aus. Da der Lastarm mit der Drehfallenachse verbunden ist, wird eine entsprechende Kraft auf die Drehfallenachse übertragen. In Abhängigkeit von der Anordnung der Teile eines Gesperres kann sich die Beanspruchung auch auf die Sperrklinke auswirken. Bei einem üblichen Schloss werden daher die einzelnen Teile eines Gesperres so stabil gebaut, dass diese nicht nur dem täglichen Betrieb, sondern auch schlagartigen Stoßbeanspruchungen gewachsen sind.If a crash causes a door to open, the locking pin exerts a corresponding pressure on the load arm. Since the load arm is connected to the rotary latch axis, a corresponding force is transmitted to the rotary latch axis. Depending on the arrangement of the parts of a locking mechanism, the stress can also affect the pawl. In a conventional lock, therefore, the individual parts of a locking mechanism are built so stable that they can cope not only with the daily operation, but also sudden impact stresses.
Aus der Druckschrift
Der Gegenstand des Anspruchs 1 löst die Aufgabe der Erfindung Vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen.The subject of
Die Aufgabe wird gelöst durch die Bereitstellung eines Schlosses mit einem Schlosskasten sowie einem Gesperre umfassend eine Drehfalle mit einem Lastarm und einem Fangarm, welche mittels einer Drehfallenachse drehbar gelagert ist. Die Drehfalle kann einen Schließbolzen aufnehmen. Das Gesperre weist eine Sperrklinke für das Verrasten der Drehfalle auf. Außerdem ist ein schwenkbarer Kraftübertragungsriegel vorhanden, mit dem eine durch einen Schließbolzen auf den Lastarm übertragene Kraft aus dem Gesperre heraus geleitet und zum Beispiel auf den Schlosskasten übertragen werden kann. Der schwenkbare Kraftübertragungsriegel ist insbesondere so angeordnet, dass vor allem die Drehfallenachse entlastet wird. Der Kraftübertragungsriegel befindet sich daher grundsätzlich auf der Seite des Einlaufschlitzes des Schlosskastens, auf der sich auch die Drehfallenachse befindet.The object is achieved by providing a lock with a lock case and a locking mechanism comprising a rotary latch with a load arm and a catch arm, which is rotatably mounted by means of a rotary latch axis. The catch can take a locking pin. The locking mechanism has a pawl for locking the catch. In addition, a pivotable power transmission latch is provided, with which a transmitted by a locking pin on the load arm force can be routed out of the locking mechanism and transmitted to the lock case, for example. The pivotable power transmission bolt is arranged in particular so that, in particular, the rotary latch axle is relieved. The power transmission bolt is therefore basically on the side of the inlet slot of the lock box on which the rotary latch axis is located.
Der Kraftübertragungsriegel befindet sich in der geöffneten Position des Schlosses bzw. des Gesperres in einer Ruhestellung. Ruhestellung meint, dass dann der Kraftübertragungsriegel keine Kräfte aus dem Gesperre heraus zu leiten und auf ein anderes Bauteil wie zum Beispiel den Schlosskasten zu übertragen vermag. Weiter ist vorgesehen, dass der Kraftübertragungsriegel in der Hauptrastposition des Gesperres in eine solche Lage geschwenkt ist, dass der Kraftübertragungsriegel übermäßige Kräfte aus dem Gesperre herauszuleiten vermag. Diese Lage wird nachfolgend "Kraftübertragungsstellung" genannt. Die dafür erforderlichen Schwenkbewegungen des Kraftübertragungsriegels können durch Federn oder andere mechanische Lösungen realisiert werden oder aber auch elektronisch oder magnetisch ausgelöst und/oder gesteuert werden.The power transmission bolt is in the open position of the lock or the locking mechanism in a rest position. Rest position means that then the power transmission bolt is unable to conduct forces out of the locking mechanism and transfer it to another component such as the lock case. It is further provided that the power transmission bolt is pivoted in the main locking position of the locking mechanism in such a position that the power transmission bolt is able to derive excessive forces from the locking mechanism. This situation is called "power transmission position" below. The necessary pivotal movements of the power transmission bar can be realized by springs or other mechanical solutions or electronically or magnetically triggered and / or controlled.
Ein Kraftübertragungsriegel eines Kraftfahrzeugschlosses wird bereits in der nicht vorveröffentlichten deutschen Patentanmeldung mit dem amtlichen Aktenzeichen
Der Einsatz des schwenkbaren Kraftübertragungsriegels zur Übertragung von übermäßigen Kräften, wie diese bei einem Crash auftreten können, vom Gesperre auf zum Beispiel den Schlosskasten erlaubt die Auslegung des Gesperres auf die im täglichen Gebrauch auftretenden Kräfte bei gleichzeitigem Vorhandensein von Sicherheitsreserven für den Notfall (Crash), da die Kräfte dann auf den Schlosskasten oder ein anderes externes Bauteil übertragen werden und nicht alleine auf die Drehfalle, die Drehfallenachse und ggfs. die Sperrklinke. Der Materialaufwand für das Schloss kann so insgesamt reduziert werden. Ein erfindungsgemäßes Schloss kann daher vorteilhaft insgesamt klein und mit geringerem Gewicht gebaut werden.The use of the pivotable power transmission bolt to transmit excessive forces, such as may occur in a crash, from the ratchet on, for example, the lock box allows the interpretation of the locking mechanism on the forces occurring in daily use while the presence of emergency reserves for emergency (crash), since the forces are then transferred to the lock case or another external component and not alone on the catch, the rotary latch axis and possibly the pawl. The cost of materials for the lock can be reduced as a whole. An inventive lock can therefore be advantageous overall small and built with less weight.
Der Kraftübertragungsriegel ist vorzugsweise derart schwenkbar gelagert, dass die Drehfalle den Kraftübertragungsriegel durch eine Drehbewegung von einer Schließstellung in die geöffnete Stellung aus seiner Kraftübertragungsstellung weg zu schwenken vermag. Wurde der Kraftübertragungsriegel auf diese Weise weggeschwenkt, so befindet sich dann in einer Ausführungsform der Kraftübertragungsriegel oberhalb oder unterhalb des Lastarms der Drehfalle und zwar von der Grundfläche der Schlossplatte aus gesehen, die grundsätzlich den Einlaufschlitz für den Schließbolzen aufweist. Insbesondere befindet sich der Kraftübertragungsriegel dann unterhalb der Drehfalle und damit unterhalb des Lastarms, weil dann auch die Schwenk- oder Drehachse des Kraftübertragungsriegels an der Grundfläche der Schlossplatte befestigt sein kann und hierfür kein zusätzliches Bauteil vorzusehen ist. Dies stellt eine besonders einfache, weiter Platz sparende Bauweise dar.The power transmission bolt is preferably pivotally mounted such that the catch is able to pivot the power transmission bolt away from its power transmission position by a rotational movement from a closed position to the open position. If the power transmission bolt has been pivoted away in this way, then in one embodiment of the power transmission bolt is above or below the Lastarms of the catch and seen from the base of the lock plate, which basically has the inlet slot for the locking pin. In particular, is located the power transmission bolt then below the catch and thus below the load arm, because then the pivot or rotation axis of the power transmission bolt can be attached to the base of the lock plate and this is no additional component to provide. This represents a particularly simple, more space-saving design.
Bereits aufgrund eines Türdichtungsdrucks steht eine relativ große Kraft bereit, die die Drehfalle von einer verrasteten Stellung in ihre Öffnungsstellung zu bewegen vermag. Das Öffnen des Gesperres wird daher für den Bediener nicht erschwert, wenn die Drehfalle einen Kraftübertragungsriegel während eines Öffnens verschwenkt.Already due to a door seal pressure is a relatively large force is ready, which is able to move the catch from a locked position to its open position. The opening of the ratchet is therefore not difficult for the operator when the catch pivots a power transmission latch during opening.
Ist der Kraftübertragungsriegel so schwenkbar mit einer Drehachse an der Schlossplatte befestigt, dass die Drehfalle den Kraftübertragungsriegel wie zuvor beschrieben nach unten aus seiner Kraftübertragungsstellung weg zu schwenken vermag, dann verläuft die Drehachse des Kraftübertragungsriegels vorzugsweise zumindest im Wesentlichen parallel zum Einlaufschlitz des Schlosskastens.If the power transmission latch is pivotally mounted to the lock plate with an axis of rotation such that the rotary latch is able to pivot the power transmission latch downwardly away from its power transmission position, then the axis of rotation of the power transmission latch preferably extends at least substantially parallel to the inlet slot of the latch box.
Ist der Kraftübertragungsriegel so schwenkbar befestigt, dass die Drehfalle den Kraftübertragungsriegel wie zuvor beschrieben aus seiner Kraftübertragungsstellung weg zu schwenken vermag, so gibt es vorteilhaft ein vorgespanntes Federelement, das den Kraftübertragungsriegel in seine Kraftübertragungsstellung zurück zu schwenken vermag. Der Kraftübertragungsriegel wird bei dieser Ausführungsform durch die Feder in seine Kraftübertragungsstellung bewegt, wenn die Drehfalle von ihrer Öffnungsstellung in Richtung Schließstellung gedreht wird und den Kraftübertragungsriegel daher freigibt.If the power transmission bolt is pivotally mounted so that the catch is able to pivot the power transmission bolt away from its power transmission position as described above, there is advantageously a biased spring element capable of pivoting the power transmission bolt back into its power transmission position. The power transmission bolt is moved in this embodiment by the spring in its power transmission position when the catch is rotated from its open position towards the closed position and therefore releases the power transmission bolt.
In einer Ausführungsform der Erfindung umfasst ein im Wesentlichen aus Metall bestehender Lastarm, der eine Ummantelung aus Kunststoff aufweisen kann, eine aus Kunststoff bestehende Nase, die gegen den Kraftübertragungsriegel stößt und diesen verschwenkt, wenn die Drehfalle aus einer verrasteten Position in die Öffnungsstellung gedreht wird. Öffnungsgeräusche werden so minimiert.In one embodiment of the invention, a substantially metal existing load arm, which may have a sheath made of plastic, a nose made of plastic, which against the Power transmission bar abuts and pivots this when the catch is rotated from a latched position to the open position. Opening noises are minimized.
In einer Ausführungsform der Erfindung gibt es wenigstens einen Mikroschalter, der durch das Schwenken des Kraftübertragungsriegels betätigt wird. Der Mikroschalter wird zu Steuerungszwecken benutzt, so zum Beispiel zum Einschalten einer Innenbeleuchtung des Fahrzeugs, wenn die Drehfalle sich nicht in der Hauptrastposition befindet. Der Mikroschalter kann außerdem dazu genutzt werden, um ein Warnsignal zu aktivieren, wenn der Kraftübertragungsriegel nicht in seine Kraftübertragungsstellung eingeschwenkt ist, obwohl die Drehfalle ihre Hauptrastposition erreicht hat. Diese Ausführungsform ermöglicht es auf einfache Weise, eine Störung anzuzeigen.In one embodiment of the invention, there is at least one microswitch actuated by the pivoting of the power transmission bar. The microswitch is used for control purposes, such as turning on interior lighting of the vehicle when the catch is not in the main latching position. The micro-switch can also be used to activate a warning signal when the power transmission latch is not pivoted into its power transmission position, even though the catch has reached its main detent position. This embodiment makes it possible to easily display a fault.
Anstelle eines Mikroschalters können auch andere Detektormittel eingesetzt werden, die ein Schwenken des Kraftübertragungsriegels in eine gewählte Position zu signalisieren vermögen. Ein solches Detektormittel kann beispielsweise ein Näherungssensor sein, der eine Annäherung des Kraftübertragungsriegels oder eines Teils des Kraftübertragungsriegels zu signalisieren vermag.Instead of a microswitch and other detector means can be used, which are able to signal a pivoting of the power transmission bar in a selected position. Such a detector means may for example be a proximity sensor capable of signaling an approach of the power transmission bar or a part of the power transmission bar.
In einer Ausführungsform der Erfindung ist der Kraftübertragungsriegel mit einem Hebelarm verbunden, mit dem ein Mikroschalter oder ein anderes Detektormittel betätigt oder ausgelöst wird, wenn der Kraftübertragungsriegel verschwenkt wird. Vorzugsweise ist der Hebelarm so angeordnet, dass dieser durch eine Öffnung der Schlossplatte hindurch geschwenkt wird, wenn der Kraftübertragungsriegel in seine Ruhestellung verschwenkt wird. Ein Mikroschalter oder ein anderes Detektormittel, der durch den Hebelarm betätigt oder ausgelöst wird, kann dann vorteilhaft auf der Seite der Schlossplatte angeordnet sein, die dem Gesperre gegenüberliegt. Die Schlossplatte trennt dann also das Gesperre von elektrischen oder elektronischen Bauteilen, die die Stellung des Kraftübertragungsriegels zu signalisieren vermögen.In one embodiment of the invention, the power transmission latch is connected to a lever arm with which a microswitch or other detection means is actuated or triggered when the power transmission latch is pivoted. Preferably, the lever arm is arranged so that it is pivoted through an opening of the lock plate, when the power transmission bolt is pivoted to its rest position. A microswitch or other detector means actuated or triggered by the lever arm may then advantageously be arranged on the side of the lock plate opposite the ratchet. The lock plate then separates so the locking of electrical or electronic components that are able to signal the position of the power transmission bolt.
In einer Ausführungsform der Erfindung umfasst das Schloss einen Hebel, der auf den Kraftübertragungsriegel einzuwirken vermag und der nachfolgend "Steuerungshebel" genannt wird. Der Steuerungshebel umfasst einen ersten Hebelarm, der von einer Ausgangsstellung ausgehend insbesondere durch den Schließbolzen bewegt wird, wenn die Drehfalle durch den Schließbolzen in Richtung Hauptraststellung gedreht wird. Der Steuerungshebel umfasst einen zweiten Hebelarm. Wird der erste Hebelarm zusammen mit der Drehfalle in Richtung Hauptraststellung bewegt, dann kann der zweite Hebelarm den schwenkbaren Kraftübertragungsriegel so erfassen und bewegen, dass der Kraftübertragungsriegel in seine Kraftübertragungsstellung eingeschwenkt wird. Alternativ oder ergänzend gelangt der zweite Hebelarm in eine solche Lage, dass in der Hauptrastposition des Gesperres der Kraftübertragungsriegel durch den zweiten Hebelarm daran gehindert wird, in seine Ruhestellung zurück zu schwenken. Die Betriebssicherheit des Schlosses wird so verbessert.In one embodiment of the invention, the lock comprises a lever capable of acting on the power transmission latch, hereinafter referred to as "control lever". The control lever comprises a first lever arm which is moved starting from a starting position, in particular by the locking pin, when the rotary latch is rotated by the locking bolt in the direction of the main locking position. The control lever comprises a second lever arm. If the first lever arm is moved together with the rotary latch in the direction of the main latching position, then the second lever arm can detect and move the pivotable power transmission latch so that the power transmission latch is pivoted into its power transmission position. Alternatively or additionally, the second lever arm reaches such a position that, in the main locking position of the locking mechanism of the power transmission bolt, it is prevented by the second lever arm from pivoting back into its rest position. The reliability of the lock is improved.
Der Steuerungshebel, der auf den Kraftübertragungsriegel einzuwirken vermag, umfasst Mittel, die den Steuerungshebel in seine Ausgangsstellung zu bewegen vermögen, wenn das Schloss geöffnet wird. Ein solches Mittel kann eine Feder sein, die den Kraftübertragungsriegel in seine Ausgangsstellung bewegt, wenn das Gesperre entrastet bzw. das Schloss geöffnet wird. Dieses Mittel kann alternativ oder ergänzend einen dritten Hebelarm umfassen, der vorzugsweise von dem Schließbolzen bewegt wird, wenn das Gesperre entrastet und der Schließbolzen aus dem Gesperre heraus bewegt wird.The control lever, which is capable of acting on the power transmission latch, includes means for moving the control lever to its home position when the latch is opened. Such means may be a spring which moves the power transmission latch to its home position when the latch is released or the lock is opened. This means may alternatively or additionally comprise a third lever arm, which is preferably moved by the locking pin when the locking mechanism is released and the locking pin is moved out of the locking mechanism.
Die vorgenannten Ausführungsformen mit dem Steuerungshebel, der auf den Kraftübertragungsriegel einzuwirken vermag, gewährleisten in verbesserter Weise, dass der Kraftübertragungsriegel sich in der Kraftübertragungsstellung befindet, wenn das Gesperre verrastet worden ist.The aforementioned embodiments with the control lever, which is able to act on the power transmission, ensure in an improved manner that the power transmission in the Power transmission position is located when the locking mechanism has been locked.
In einer Ausführungsform der Erfindung wird der zweite Hebelarm durch den Kraftübertragungsriegel an einer Bewegung gehindert, wenn der Kraftübertragungsriegel zum Beispiel aufgrund einer Beschädigung nicht durch eine Feder oder ein entsprechend wirkendes Mittel in die Kraftübertragungsstellung eingeschwenkt werden kann. Eine Tür oder Klappe kann dann nicht mehr ordnungsgemäß verschlossen werden. Eine entsprechende Beschädigung bleibt also bei dieser Ausführungsform nicht unbemerkt.In one embodiment of the invention, the second lever arm is prevented from moving by the power transmission latch when, for example, the power transmission latch can not be pivoted into the power transmission position by a spring or a correspondingly acting means due to damage. A door or flap can then no longer be properly closed. A corresponding damage does not go unnoticed in this embodiment.
In einer Ausführungsform der Erfindung umfasst die Drehfalle eine Hauptrast und eine Vorrast. Der erste Hebelarm des Steuerungshebels ist dann vorzugsweise so dimensioniert und wird so zusammen mit der Drehfalle während eines Schließvorgangs gedreht, dass eine Sperrklinke zunächst nicht in die Vorrast einzurasten vermag. Es wird beim Schließvorgang ein andernfalls auftretendes Geräusch aus den in der nicht vorveröffentlichten deutschen Patentanmeldung mit dem amtlichen Aktenzeichen
Unterdrückt der erste Hebelarm zunächst das Einrasten einer Sperrklinke in die Vorrast, so kann die Drehfalle nur dann in der Vorrastposition verrastet werden, wenn die Drehfalle über die Vorrast hinaus gedreht wurde, die Hauptrastposition aber nicht erreicht hat und daher anschließend in Richtung Öffnungsstellung zurückdreht.Suppresses the first lever arm first, the engagement of a pawl in the pre-catch, the catch can only be latched in the pre-locking position when the catch rotated beyond the pre-rest was, the main position but has not reached and therefore subsequently backwards in the direction of opening position.
In einer Ausführungsform der Erfindung hindert eine Sperrklinke des Gesperres in der Hauptrastposition den Steuerungshebel daran, in seine Ausgangsstellung gelangen zu können, von der aus der Steuerungshebel den Kraftübertragungsriegel in seine Kraftübertragungsstellung zu bewegen vermag. Der Steuerungshebel kann erst in seine Ausgangsstellung geschwenkt oder gedreht werden, wenn die Sperrklinke weg geschwenkt wird. Insbesondere ist die Sperrklinke, die die Drehfalle in der Hauptrastposition verrastet, zugleich die Sperrklinke, die den Steuerungshebel daran hindert, in der Hauptrastposition in seine Ausgangsstellung zurückgedreht oder geschwenkt zu werden.In one embodiment of the invention, a pawl of the locking mechanism in the main latching position prevents the control lever from being able to reach its starting position, from which the control lever is able to move the power transmission latch into its power transmission position. The control lever can only be pivoted or rotated to its initial position when the pawl is pivoted away. In particular, the pawl, which locks the catch in the main latching position, at the same time the pawl, which prevents the control lever from being turned back or pivoted in the main latching position to its initial position.
In einer Ausführungsform der Erfindung gibt es eine vorgespannte Druckfeder, die den Steuerungshebel in seine beiden Endstellungen zu bewegen vermag. In der einen Endstellung drückt der zweite Hebelarm des Steuerungshebels gegen den Kraftübertragungsriegel und trägt so dazu bei, dass der Kraftübertragungsriegel zuverlässig in seiner Kraftübertragungsstellung gehalten wird. Die andere Endstellung ist die vorgenannte Ausgangsstellung. Befindet sich der Steuerungshebel beispielsweise in seiner Ausgangsstellung und wird dieser mit Hilfe eines Schließbolzens in Richtung seiner anderen Endstellung gedreht, so erreicht der Hebel einen Umkehrpunkt, von dem aus die vorgespannte Druckfeder den Steuerungshebel in seine andere Endstellung hineindrückt. Befindet sich der Steuerungshebel in seiner anderen Endstellung und wird der Steuerungshebel zum Beispiel mit Hilfe eines Schließbolzens in Richtung seiner Ausgangsstellung gedreht, so erreicht der Hebel wiederum den genannten Umkehrpunkt, von dem aus die vorgespannte Druckfeder dann den Steuerungshebel in seine Ausgangsstellung hineindrückt. Bei dieser Ausführungsform wird sichergestellt, dass der Steuerungshebel stets vollständig in seine jeweilige Endstellung hinein bewegt wird und sich aus einer solchen Endstellung nicht unplanmäßig heraus bewegt. Hierdurch wird die Betriebssicherheit des Gesperres weiter verbessert. Ist außerdem der Steuerungshebel zugleich als Vorrastunterdrückungshebel ausgestaltet, so wird so sichergestellt, dass der Steuerungshebel während des Schließens einer zugehörigen Fahrzeugtür oder Fahrzeugklappe nicht unplanmäßig zusammen mit der Drehfalle in Richtung Öffnungsstellung zurückgedreht werden kann, wenn die Hauptrastposition nicht erreicht wird. Die Möglichkeit des Verrastens in der Vorrastposition wird so verbessert sichergestellt.In one embodiment of the invention, there is a preloaded compression spring which is able to move the control lever in its two end positions. In one end position, the second lever arm of the control lever presses against the power transmission bolt and thus contributes to the fact that the power transmission bolt is reliably held in its power transmission position. The other end position is the aforementioned starting position. The control lever is, for example, in its initial position and this is rotated by means of a locking pin in the direction of its other end position, the lever reaches a reversal point, from which the biased compression spring pushes the control lever in its other end position. If the control lever is in its other end position and the control lever is rotated, for example, by means of a locking bolt in the direction of its initial position, the lever in turn reaches said reversal point, from which the prestressed compression spring then pushes the control lever into its initial position. In this embodiment, it is ensured that the control lever is always moved completely into its respective end position and does not move out of such an end position unscheduled out. This will be the Operational safety of the locking further improved. In addition, if the control lever is also designed as Vorrastunterdrückungshebel, so it is ensured that the control lever during the closing of an associated vehicle door or vehicle door can not be unintentionally turned back together with the catch in the open position when the main detent position is not reached. The possibility of latching in the pre-locking position is thus improved.
In einer Ausführungsform der Erfindung umfasst die Drehfalle einen Anschlag für den Steuerungshebel. Dieser Anschlag ist so angeordnet, dass dieser ergänzend sicherzustellen vermag, dass der Steuerungshebel in Richtung Ausgangsstellung bewegt wird, wenn das Gesperre entrastet wird. Diese Ausführungsform stellt sicher, dass der Steuerungshebel auch dann in seine Ausgangsstellung zurückbewegt werden kann, wenn das Gesperre verrastet worden ist, ohne dass sich ein Schließbolzen im Einlaufschlitz befindet.In one embodiment of the invention, the rotary latch comprises a stop for the control lever. This stop is arranged so that it can additionally ensure that the control lever is moved in the direction of the starting position when the locking mechanism is unlatched. This embodiment ensures that the control lever can be moved back to its initial position even if the locking mechanism has been latched without a locking pin in the inlet slot.
In einer Ausführungsform der Erfindung ist das Schloss so gestaltet, dass ein Verschwenken des Kraftübertragungsriegel in seine Ruhestellung den Steuerungshebel erfasst und in Richtung Ausgangsstellung bewegt. Diese Ausführungsform stellt im Vergleich zur vorgenannten Ausführungsform alternativ oder ergänzend sicher, dass der Steuerungshebel auch dann in seine Ausgangsstellung zurückbewegt werden kann, wenn das Gesperre verrastet worden ist, ohne dass sich ein Schließbolzen im Einlaufschlitz befindet.In one embodiment of the invention, the lock is designed so that a pivoting of the power transmission latch in its rest position detects the control lever and moves in the direction of the starting position. This embodiment provides as an alternative or in addition to the aforementioned embodiment, that the control lever can be moved back to its initial position even if the locking mechanism has been locked without a locking pin is in the inlet slot.
In einer Ausführungsform gibt es einen Anschlag für den Steuerungshebel. Der Steuerungshebel erreicht diesen Anschlag, wenn er vollständig in seine Ausgangsstellung hinein bewegt worden ist.In one embodiment, there is a stop for the control lever. The control lever reaches this stop when it has been fully moved into its home position.
Der Steuerungshebel besteht vorteilhaft aus Kunststoff, um das Gewicht des Schlosses gering zu halten.The control lever is advantageously made of plastic to keep the weight of the lock low.
Der vorgenannte Steuerungshebel, der auf den Kraftübertragungsriegel einwirkt, ist auch dann vorteilhaft, wenn der Kraftübertragungsriegel zwar wie beschreiben zwischen zwei Stellungen aus den genannten Gründen hin und zurück geschwenkt werden kann, aber die Ruhestellung des Kraftübertragungsriegels nicht außerhalb der Ebene liegt, innerhalb der die Drehfalle gedreht werden kann. Der Steuerungshebel kann also Gegenstand einer eigenständigen Erfindung sein, die nicht sämtliche Merkmale des Anspruchs 1 umfasst.The aforementioned control lever, which acts on the power transmission bar, is also advantageous when the power transmission bar as described can be pivoted back and forth between two positions for the reasons mentioned above, but the rest position of the power transmission bar is not outside the plane within which the catch can be turned. The control lever can therefore be the subject of an independent invention, which does not comprise all the features of
Der Schlosskasten bzw. die Schlossplatte ist bevorzugt zweiteilig aufgebaut. Der Schlosskasten umfasst zu einem eine metallische Platte, auf der die Drehfalle und die Sperrklinke drehbar angebracht sind. Umfasst das Gesperre darüber hinaus einen Steuerungshebel, so wird dieser vorzugsweise ebenfalls an der metallischen Platte drehbar angebracht.The lock case or the lock plate is preferably constructed in two parts. The lock case comprises a metallic plate on which the catch and the pawl are rotatably mounted. In addition, if the locking mechanism comprises a control lever, it is preferably also rotatably mounted on the metallic plate.
Darüber hinaus besteht der Schlosskasten aus Kunststoff, um das Gewicht des Schlosses zu minimieren. Der aus Kunststoff bestehende Teil des Schlosskastens ist mit der metallischen Platte vorzugsweise fest verbunden, so zum Beispiel mittels einer Schraub-, Niet- und/ oder Klebeverbindung. Sollte es zum Beispiel aus Stabilitätsgründen zweckmäßig sein, so besteht der Schlosskasten vollständig aus Metall.In addition, the lock case is made of plastic to minimize the weight of the lock. The plastic part of the lock case is preferably fixedly connected to the metallic plate, for example by means of a screw, rivet and / or adhesive connection. Should it be expedient for reasons of stability, for example, then the lock case is made entirely of metal.
Die metallische Platte des Schlosskastens verläuft vorzugsweise winkelförmig um den Einlaufschlitz des Schlosskastens herum. Am einen Ende des Winkels ist die Sperrklinke des Gesperres drehbar befestigt und am anderen Ende die Drehfalle. Der metallische Anteil des Schlosskastens und damit sein Gewicht werden so minimiert.The metallic plate of the lock case preferably extends angularly around the inlet slot of the lock case. At one end of the angle, the pawl of the locking mechanism is rotatably mounted and at the other end the catch. The metallic part of the lock case and thus its weight are minimized.
Vorteilhaft gibt es einen metallischen Streifen, der sich vom Schlosskasten aus gesehen oberhalb der Drehfalle und der Sperrklinke befindet. An den beiden Enden dieses metallischen Streifens sind die Achsen von Drehfalle und Blockadehebel befestigt. Diese Ausführungsform trägt dazu bei, einerseits die erforderliche Stabilität bereitzustellen und dennoch das Gewicht durch einen hohen Kunststoffanteil gering zu halten.Advantageously, there is a metallic strip, which is seen from the lock case above the catch and the pawl. At the two ends of this metallic strip, the axes of the catch and the blocking lever are attached. These Embodiment contributes on the one hand to provide the required stability and still keep the weight low by a high plastic content.
Da bei dem erfindungsgemäßen Schloss übermäßige Kräfte aus dem Gesperre heraus geleitet werden, können sämtliche Bauteile des Gesperres sehr klein ausgeführt werden, so zum Beispiel der Durchmesser der Drehfallenachse, damit einhergehend der Abstand zwischen Einlaufschlitz der Drehfalle und Drehfallenachse sowie die Breite von Lastarm der Drehfalle. So kann eine Schlosskastenbreite von maximal 7 cm realisiert werden. Schlosskastenbreite meint die Erstreckung des Schlosskastens entlang des Einlaufschlitzes des Schlosskastens. Was unter Schlosskastenbreite zu verstehen ist, wird ferner auch anhand der weiter unten beschriebenen Ausführungsbeispiele deutlich.Since excessive forces are conducted out of the locking mechanism in the lock according to the invention, all components of the locking mechanism can be made very small, such as the diameter of the rotary latch axis, along with the distance between the inlet slot of the rotary latch and rotary latch axis and the width of the load arm of the rotary latch. Thus, a lock case width of a maximum of 7 cm can be realized. Lock box width means the extent of the lock case along the inlet slot of the lock case. What is meant by lock case width is also clear from the embodiments described below.
Der schwenkbare Kraftübertragungsriegel ist insbesondere am Schlosskasten befestigt und/ oder so angeordnet, dass dieser von einer seitlichen Wand des Schlosskastens in der Hauptrastposition bis zur Drehfalle reicht. Diese seitliche Wand grenzt in einem rechten Winkel an den Schlosskasten-Einlaufschlitz für den Schließbolzen an. Der Kraftübertragungsriegel ist insbesondere benachbart zum Einlaufschlitz des Schlosskastens angeordnet und zwar bevorzugt auf der Seite des Einlaufschlitzes, auf der auch die Drehfallenachse angeordnet ist. In der Hauptrastposition grenzt der Kraftübertragungsriegel dann derart seitlich an die Drehfalle, dass die Drehfalle bei den beschriebenen schlagartigen Beanspruchungen gegen den Kraftübertragungsriegel gedrückt wird. Der Kraftübertragungsriegel nimmt dann die entsprechende Kraft auf und leitet diese an den Schlosskasten weiter und zwar aufgrund seiner Befestigung und/ oder aufgrund seiner Abstützung an einer entsprechenden seitlichen Schlosskastenwand.The pivotable power transmission bolt is in particular attached to the lock case and / or arranged so that it extends from a side wall of the lock case in the main latching position to the catch. This lateral wall adjoins the lock box entry slot for the lock bolt at a right angle. The power transmission bolt is arranged in particular adjacent to the inlet slot of the lock case, and preferably on the side of the inlet slot on which the rotary latch axis is arranged. In the main locking position, the power transmission bolt then adjoins the rotary latch in such a manner that the rotary latch is pressed against the power transmission bolt in the case of the abrupt stresses described. The power transmission bolt then absorbs the corresponding force and forwards it to the lock case, and indeed because of its attachment and / or due to its support on a corresponding side lock case wall.
Der Kraftübertragungsriegel kann ganz oder teilweise aus Metall bestehen und aus dem gleichen oder einem anderen Material wie die Drehfalle gefertigt sein. Bevorzugt besteht der Kraftübertragungsriegel jedoch aus Kunststoff und zwar insbesondere, wenn dieser sich an einer entsprechenden seitlichen Schlosskastenwand abstützt. Der Kraftübertragungsriegel ist dann einerseits relativ leicht und kann andererseits stabil genug konstruiert werden, um den beschriebenen Anforderungen gewachsen zu sein. Alternativ zu einer seitlichen Schlosskastenwand kann sich der Kraftübertragungsriegel im eingebauten Zustand des Schlosses stets auch an einer Wand des Fahrzeugs abstützen, um in der Hauptrastposition Kräfte aus dem Gesperre geeignet auf andere Bauteile zu übertragen, also zum Beispiel in eine Fahrzeugtür oder Fahrzeugklappe hinein.The power transmission bolt may be wholly or partly made of metal and of the same or a different material as the Be made catch. Preferably, however, the power transmission bolt is made of plastic and in particular if it is supported on a corresponding side lock case wall. The power transmission bar is then on the one hand relatively light and on the other hand can be constructed stably enough to cope with the described requirements. As an alternative to a lateral lock case wall, the power transmission bolt in the installed state of the lock can always also be supported on a wall of the vehicle in order to transfer forces from the locking mechanism to other components in the main latching position, for example into a vehicle door or vehicle door.
Der Kraftübertragungsriegel ist bevorzugt innerhalb des Schlosskastens angeordnet. Besonders bevorzugt ist er in räumlicher Nähe zur Drehfallenachse angeordnet, ganz besonders bevorzugt in räumlicher Nähe zum Lastarm, insbesondere in räumlicher Nähe zum Lastarm und zur Drehfallenachse. Ein derart angeordneter Kraftübertragungsriegel erfordert grundsätzlich keinen zusätzlichen Bauraum.The power transmission bolt is preferably arranged within the lock case. Particularly preferably, it is arranged in spatial proximity to the rotary latch axis, very particularly preferably in spatial proximity to the load arm, in particular in spatial proximity to the load arm and the rotary latch axis. Such arranged power transmission bar basically requires no additional space.
Bevorzugt berührt der Kraftübertragungsriegel die Drehfalle, vorzugsweise den Lastarm der Drehfalle nur dann, wenn aufgrund von starken Kräften die Drehfalle in der Hauptrastposition in Richtung Kraftübertragungsriegel verschoben wird. Es wird so das Auftreten von Reibungskräften während des Regelbetriebs aufgrund einer regelmäßigen Berührung zwischen Drehfalle und Kraftübertragungsriegel vorteilhaft vermieden. Der Abstand zwischen Kraftübertragungsriegel und Drehfalle ist so klein gewählt, dass die Drehfallenachse nicht derart verformt werden kann, dass diese bricht, bevor die Drehfalle durch den Kraftübertragungsriegel abgestützt wird.Preferably, the power transmission bar touches the catch, preferably the load arm of the catch only when due to strong forces, the catch is moved in the main latching position in the direction of power transmission bolt. It is thus advantageously avoided the occurrence of frictional forces during normal operation due to a regular contact between the rotary latch and power transmission. The distance between the power transmission bolt and the rotary latch is chosen so small that the rotary latch axle can not be deformed so that it breaks before the catch is supported by the power transmission bar.
Der Kraftübertragungsriegel ist bevorzugt quaderförmig, da der zur Verfügung stehende Bauraum dann optimal genutzt werden kann. Es sind aber auch andere Kraftübertragungsriegelgeometrien, wie zum Beispiel stabförmige oder halbmondförmige Ausgestaltungen einsetzbar.The power transmission bolt is preferably cuboid, since the available space can then be used optimally. But there are also other Krafttragungsriegelgeometrien, such as Example rod-shaped or crescent-shaped embodiments used.
Bevorzugt befindet sich der Kraftübertragungsriegel in der Hauptrastposition der Drehfalle in räumlicher Nähe zum Lastarm, besonders bevorzugt gelangt der Kraftübertragungsriegel in eine Ausbuchtung des Lastarms hinein, um so besonders zuverlässig seine Position beizubehalten, wenn hohe Kräfte von der Drehfalle auf diesen übertragen werden.Preferably, the power transmission bolt is in the main detent position of the rotary latch in spatial proximity to the load arm, particularly preferably the power transmission latch enters a bulge of the load arm so as to maintain its position particularly reliably when high forces are transmitted from the rotary latch to the latter.
Entweder kann der Kraftübertragungsriegel besonders fest an einer Schlosskastenwand verankert sein, an der er zum Beispiel beweglich gelagert ist, beispielsweise durch eine Führung oder Niete und/oder er kann in der Hauptrastposition der Drehfalle bei hoher Last sowohl den Lastarm als auch wenigstens eine seitliche Schlosskastenwand berühren.Either the power transmission bolt can be particularly firmly anchored to a lock case wall on which it is for example mounted movably, for example by a guide or rivet and / or it can touch both the load arm and at least one lateral lock case wall in the main load position of the catch at high load ,
Kräfte werden in einer Ausführungsform vom Kraftübertragungsriegel in seine Drehachse eingeleitet. Von dieser Achse aus werden Kräfte dann in die Haltemittel eingeleitet, die die Achse drehbar halten.Forces are introduced in one embodiment of the power transmission bar in its axis of rotation. From this axis forces are then introduced into the holding means, which hold the axis rotatable.
Erfindungsgemäß kann die Drehfalle ganz oder teilweise aus Metall bestehen. Als Metall im Rahmen der Erfindung kommt hierbei bevorzugt Stahl, gehärteter Stahl oder eine Stahllegierung zur Anwendung. Bevorzugt wird im Rahmen der vorliegenden Erfindung wenigstens der Lastarm aus Metall gefertigt oder mit Metall verstärkt. Als Metall im Rahmen der Erfindung kommen bevorzugt Stahl, gehärteter Stahl und Stahllegierungen zur Verwendung.According to the invention, the catch completely or partially made of metal. As metal in the context of the invention here preferably steel, hardened steel or a steel alloy is used. In the context of the present invention, at least the load arm is preferably made of metal or reinforced with metal. As the metal in the invention are preferably steel, hardened steel and steel alloys for use.
Die Drehfalle kann ganz oder teilweise mit Kunststoff ummantelt sein. Einzelne Bestandteile der Drehfalle, insbesondere der auch in Crashsituationen vergleichsweise gering belastete Fangarm können teilweise oder vollständig aus Kunststoff gefertigt sein, um das Schloss leicht und kostengünstig auszugestalten.The catch can be completely or partially encased in plastic. Individual components of the rotary latch, in particular the catch arm, which is comparatively slightly loaded even in crash situations, can be used partially or completely made of plastic, to make the lock easy and inexpensive.
Die Sperrklinke kann aus Metall oder Kunststoff ausgebildet sein. Bevorzugt ist sie jedoch aus Metall ausgeführt.The pawl may be formed of metal or plastic. Preferably, however, it is made of metal.
Bevorzugt ist sowohl die Vorrast als auch die Hauptrast am Lastarm ausgeführt. Dies erlaubt eine Bauweise des Fangarmes mit geringem Gewicht und trägt zur Gewichtsreduktion und Kompaktheit der Gesamtkonstruktion bei. Hierbei sind die Rastpositionen bevorzugt ganz oder teilweise aus Metall ausgeformt.Preferably, both the pre-rest and the main rest is performed on the load. This allows a construction of the tentacle with low weight and contributes to the weight reduction and compactness of the overall construction. Here, the locking positions are preferably formed entirely or partially of metal.
Die schmalste Stelle Lastarm der Drehfalle ist bevorzugt breiter als die breiteste Stelle des Fangarms, da vor allem der Lastarm belastet wird. Der Bauraum für ein Schloss kann so weiter reduziert werden.The narrowest point of the load arm of the catch is preferably wider than the widest point of the catching arm, since above all the load arm is loaded. The installation space for a lock can be further reduced.
In einer Ausführungsform der Erfindung umfasst das Schloss einen Schließbolzen, der einen Querschnitt in Form eines abgeflachten Kreises im Sinne der nicht vorveröffentlichten deutschen Patentanmeldung mit dem amtlichen Aktenzeichen
Der Bereich der Drehfalle, der die Drehfallenachse umschließt, ist vorzugsweise aus Stabilitätsgründen zumindest teilweise aus Metall gefertigt. Um Gewicht zu reduzieren und um ein Schloss mit geringem Kraftaufwand öffnen zu können, umschließt ein metallischer Bereich der Drehfalle die Drehfallenachse nur teilweise und zwar in der aus der nicht vorveröffentlichten deutschen Patentanmeldung mit dem amtlichen Aktenzeichen
Vorzugsweise ist das Sperrteilverhältnis des Gesperres in einer Ausführungsform gleich oder größer als 3, um das Schloss mit geringem Kraftaufwand öffnen zu können. Ein derart großes Sperrteilverhältnis lässt sich besonders leicht durch aus den deutschen Patentanmeldungen mit dem amtlichen Aktenzeichen
Durch jede dieser Maßnahmen im Einzelnen und vor allem im gegenseitigen Zusammenspiel entstehen besonders günstige Kraftverteilungsverhältnisse im täglichen Betrieb und in Crashsituationen, die eine kompakte Bauweise mit geringem Gewicht bei hoher Sicherheit erlauben.By each of these measures in detail and especially in mutual interaction arise particularly favorable power distribution conditions in daily operation and in crash situations that allow a compact design with low weight and high security.
Das erfindungsgemäße Schloss eignet sich hervorragend für den Einsatz in Kraftfahrzeugen. Es ist leichter und kostengünstiger im Vergleich zu herkömmlichen Schlössern.The lock according to the invention is outstandingly suitable for use in motor vehicles. It is easier and less expensive compared to traditional locks.
Nachfolgend werden Ausführungsbeispiele der vorliegenden Erfindung beschrieben.Hereinafter, embodiments of the present invention will be described.

Die Drehfalle umfasst noch eine Vorrast 1a. In dieser kann die Sperrklinke die Drehfalle beispielsweise dann verrasten, wenn eine zugehörige Tür oder Klappe mit nicht hinreichender Geschwindigkeit oder Kraft geschlossen wurde, und die Drehfalle daher die Hauptrastposition nicht erreicht hat.The catch also includes a pre-rest 1a. In this, the pawl can lock the catch, for example, when an associated door or flap was closed with insufficient speed or force, and the catch has therefore not reached the main detent position.

Hierdurch wird der Steuerungshebel in seine Ausgangsstellung hinein bewegt.The control lever, which is able to act on the
Wird der erste Hebelarm 16 des Steuerungshebels bzw. des Vorrastunterdrückungshebels gemeinsam mit dem Fangarm 2 der Drehfalle durch einen Schließbolzen in Richtung Schließstellung gedreht, so befindet sich eine Auflagefläche 16a des ersten Hebelarms 16 oberhalb der Vorrast 1a. Aufgrund des Vorsprungs 8 der Sperrklinke 3 kann daher die Sperrklinke 3 nicht in die Vorrast 1a hinein bewegt werden, wenn sich die Drehfalle gemeinsam mit dem Vorrastunterdrückungshebel in Richtung Schließstellung bewegt. Daher gleitet dann der Hebelarm 21 der Sperrklinke 3 geräuschlos über den seitlichen Konturbereich mit der Vorrast 1a hinweg. Verläuft alles planmäßig, dann rastet der Hebelarm 21 der Sperrklinke 3 schließlich in der Hauptrast 1 b ein. Sollte die Drehfalle allerdings die Hauptrastposition nicht vollständig erreichen und sich wieder zurückdrehen, so wird sich der Steuerungshebel bzw. der Vorrastunterdrückungshebel nicht sofort ebenfalls zurückdrehen, da der Schließbolzen erst verzögert den dritten Hebelarm 18 erfassen wird. Aufgrund dieser unterschiedlichen Bewegung gibt dann der erste Hebelarm 16 den darunter befindlichen seitlichen Bereich der Drehfalle mit der Vorrast 1a frei, so dass der Hebelarm 21 der Sperrklinke 3 nun in die Vorrast- einzurasten vermag.If the
Der Vorsprung 8 der Sperrklinke 3 hindert in der Hauptrastposition den Steuerungshebel daran, in seine Ausgangsstellung zu gelangen. Sollte sich der Steuerungshebel unplanmäßig in seine Ausgangsstellung drehen wollen, so stößt das Ende des ersten Hebelarms 16 gegen den Vorsprung 8, was das Fortsetzen der Drehbewegung verhindert. Der Steuerungshebel kann also erst in seine Ausgangsstellung geschwenkt oder gedreht werden, wenn die Sperrklinke 3 aus der Raststellung heraus geschwenkt worden ist.The projection 8 of the
