Definitions
- the invention relates to a motor vehicle locking device, with a coupling arrangement consisting essentially of an actuating lever and a release lever that can be detachably coupled to it, wherein the actuating lever and the release lever can be coupled to one another, starting from a disengaged basic position, by a two-stroke actuation of the actuating lever, and wherein a first stroke of the Actuating lever is provided storing memory lever, so that the actuating lever can act upon the release lever following the storage lever in its second stroke.
- Motor vehicle locking devices with coupling arrangements consisting essentially of an actuating lever and a release lever that can be detachably coupled thereto are often used as a motor vehicle locking device in connection with the realization of an internal actuating lever chain in motor vehicle locks.
- internal actuating lever chains are often acted upon in so-called two-stroke operation for safety reasons.
- the first stroke of the actuating lever serves to unlock the motor vehicle lock and in particular the motor vehicle door lock.
- a locking mechanism provided at the end of the actuating lever chain and previously closed is opened. This prevents unintentional door openings, which increases security.
- the invention is based on the technical problem of further developing such a motor vehicle locking device in such a way that the usual two-stroke actuation can be retained even if a safety function or safety unit is additionally implemented.
- the invention based on a generic motor vehicle locking device, proposes within the scope of the invention that a safety lever is additionally provided which, in its "secured” position, prevents a subsequent movement of the release lever during the second stroke of the actuating lever and in its "position” unlocked” allows.
- the securing lever is therefore firstly and additionally realized in addition to the clutch arrangement consisting essentially of the actuating lever and the release lever that can be detachably coupled to it, as well as the storage lever.
- the safety lever can be part of a safety unit.
- This security unit may be non-limitingly a child security unit. In principle, however, the security unit can also be a locking unit, an anti-theft device or a combination.
- the design within the scope of the invention is such that the safety lever in its “secured” position prevents the subsequent movement of the release lever during the second stroke of the actuating lever.
- the storage lever does not assume a storage position to be explained in more detail below when the safety lever is in the “secured” position.
- the release lever cannot follow the storage lever either and accordingly open the locking mechanism. According to the invention, such a subsequent movement of the release lever during the second stroke of the actuating lever is only possible if the safety lever assumes its “unlocked” position.
- the motor vehicle locking device is reset to its starting position, so that irritation of the user is avoided in this respect as well.
- the safety lever can advantageously be acted upon manually and/or by an electric motor, so that the motor vehicle
- Closing devices or motor vehicle door locks can easily be synchronized on each rear motor vehicle side doors. This is where the main advantages can be seen.
- the further design is such that the safety lever interacts with a latching element which is set up to implement the previously described and releasable storage position of the storage lever.
- the safety lever usually has a carrier contour. With the help of the entrainment contour, the locking element in question can experience an impact on the part of the safety lever.
- the procedure here is usually such that the safety lever transfers and can transfer the latching element via the entrainment contour from a latching position permitting the storage position of the storage lever to a release position preventing the storage position and vice versa.
- an additional stop contour is usually also provided.
- the stop contour of the safety lever is designed to interact with a handle and/or an electric motor drive. In this way, the safety lever can easily be transferred to its desired functional position “secured” or “unsecured” manually, for example, via the handle or by remote control via the electric motor drive or by both procedures.
- the "secured" position of the safety lever corresponds to the fact that the release lever cannot follow the second stroke of the actuating lever, and the locking mechanism is closed accordingly
- the “unlocked” position of the safety lever corresponds to the release lever following the stroke of the actuating lever during the second stroke of the actuating lever and opening the locking mechanism accordingly.
- the acted upon release lever usually works on a pawl as part of the locking mechanism made up of pawl and rotary latch. Since the pawl is in latching engagement with the rotary latch when the locking mechanism is in the closed state, an opening movement on the part of the release lever causes the pawl to be lifted from its latching engagement with the rotary latch. The spring-loaded rotary latch then opens and releases a previously caught locking bolt.
- the associated motor vehicle door and the relevant motor vehicle lock or motor vehicle door lock can be opened.
- a sensor that queries the safety lever is provided.
- This sensor can be used to query the respective position and position of the safety lever in the sense of "unlocked” or “secured".
- the sensor is a switch that is acted upon, for example, via a contour on the safety lever.
- a shift lever is implemented in addition to the storage lever.
- the shift lever is generally elastically coupled to the storage lever via a spring.
- the spring elastically coupling the two levers ensures that the switching lever ultimately follows the storage lever that is in its storage position and remains temporarily.
- the actuating lever follows the accumulator lever that is in the storage position, and the actuating lever can thereby act on the shift lever.
- the shift lever in this position, the shift lever usually rests against the release lever with a stop contour interacting with the release lever, the second stroke of the actuating lever is transferred to the release lever, which opens the locking mechanism as desired - as described.
- the shift lever, the storage lever and the release lever are usually and advantageously mounted coaxially with one another and rotatably. That is, the three aforementioned levers have a common axis for their rotary movement.
- a motor vehicle locking device is made available that still requires two-stroke actuation in order to be able to open the locking mechanism, even if the additionally provided safety lever and consequently a corresponding safety unit assumes its “unlocked” position.
- the safety lever is additionally implemented or not.
- FIGS. 7 to 14 the relevant motor vehicle locking device with the safety lever remaining in the “unlocked” position.
- FIGS. 1 and 14 show a motor vehicle locking device which initially has a locking mechanism 1 consisting essentially of a rotary latch and a pawl.
- the locking mechanism 1 is in a closed state, in which the pawl engages in the catch in a latching manner.
- FIG. 14 shows an opening process of the locking mechanism 1, which corresponds to the locking mechanism 1 being acted upon with the aid of a release lever 2.
- the release lever 2 it is necessary for the release lever 2 to pivot in a clockwise direction about its axis 3, as can be understood by comparing FIGS.
- the basic structure of the motor vehicle locking device includes a clutch arrangement 2, 4, which is composed of the release lever 2 already mentioned on the one hand and an actuating lever 4 on the other hand.
- the actuating lever 4 is mounted so as to be rotatable about its own further axis of rotation 5 spaced apart from the axis 3 .
- a safety lever 6 is then realized, which is mounted so that it can rotate about an axis 7 and can be acted upon with the aid of an electric motor drive 8 .
- This corresponds to rotary movements of the safety lever 6 about its axis 7 in the clockwise direction, as can be understood by comparing FIGS.
- This is accompanied by a change in the functional position of the safety lever 6.
- this is in its “unlocked” position, whereas the safety lever 6 occupies its “secured” position in each of FIGS.
- the safety lever 6 is equipped with a stop contour 6a, which interacts with the electric motor drive 8 or from
- the transition from the "unlocked" position of the safety lever 6 according to Fig. 1 to the “secured” position as shown in Fig. 2 corresponds to the electric motor drive 8 performing a more or less pronounced linear movement and thus over the Stop contour 6a pivots the safety lever 6 clockwise about its axis 7 as desired.
- the described pivoting movement of the safety lever 6 can also be carried out manually using a handle through a corresponding interaction with the stop contour 6a, although this is not shown in detail.
- a storage lever 9 can also be seen, which can interact with an additionally provided latching element 10 .
- the storage lever 9 and the latching element 10 have corresponding and interlocking latching elements 9a, 10a.
- the latching elements 9a, 10a only interact if the latching element 10 assumes its latching position shown in FIG from FIG. 1 to FIG. 9 can be traced.
- the storage lever 9 assumes the storage position shown in FIG. 9.
- the latching element 10 assumes its release position, as is shown by way of example in FIG. 2, there is no latching interaction between the two latching elements 9a, 10a. In order to transfer the latching element 10 from its latching position as shown in FIG. 1 to the release position, for example according to FIG. In addition
- the safety lever 6 has a driving contour 6b, which is used to act on the latching element 10.
- the figures also show a sensor 11 which, according to the exemplary embodiment and not by way of limitation, is a switch.
- the sensor 11 or switch may be connected to a control unit, not shown, which is not only set up to query the position of the safety lever 6 via the sensor 11 but also serves to control the electric motor drive 8 .
- the position of the safety lever 6 is queried using the sensor or switch 11 in such a way that the safety lever 6 has a switching contour 6c shown in the detail in Fig. 1, which has a spring belonging to the sensor or switch 11 and thus the sensor or switch 11 applied when the safety lever 6 changes from its “unlocked” position as shown in FIG. 1 to the “secured” position according to FIG. 2, as can be understood from the respective excerpts there.
- the actuating lever 4 and the release lever 2 not only define the clutch arrangement 2, 4 already described, but also the actuating lever 4 and the release lever 2 starting from a disengaged basic position shown in FIG a two-stroke actuation of the actuation lever 2, which is to be described in detail below, can be coupled to one another, as can ultimately be understood from FIGS. 13 and 14.
- the procedure is such that first the storage lever 9 storing the first stroke of the actuating lever 4 is provided. That is, the first stroke of the operating lever 4 ensures that the storage lever 9 moves into its storage position, as shown in FIGS. In this way, the actuating lever 4 in its second stroke to the
- the safety lever 9 is now also provided, which in its "secured” position shown in Figures 2 to 6 prevents the previously described subsequent movement of the release lever 2 during the second stroke of the actuating lever 4 and allows it in its "unlocked” position, as the sequence of figures in Figures 10 to 14 makes clear.
- a shift lever 12 is implemented in addition to the safety lever 6 and the storage lever 9 is also of particular importance.
- the shift lever 12 is coupled to the storage lever 9 via a spring 13 .
- the shift lever 12 has a stop contour 12a that interacts with the release lever 2 .
- another stop contour 12b is realized on the shift lever 12, which is described below.
- the release lever 2 can be pivoted clockwise about its axis 3 using the actuating lever 4 and is able to release the locking mechanism 1 to open.
- the shift lever 12 , the storage lever 9 and finally the release lever 2 are mounted on the same axis as one another and each can be rotated about the common axis 3 .
- the actuating lever 4 is again subjected to a first stroke, in such a way that the actuating lever 4 performs the previously described counterclockwise movement about its axis 5, this is what happens
- the storage lever 9 in the functional position of FIG. 9 is transferred to the storage position already mentioned.
- the two latching contours 9a, 10a engage on the one hand on the latching element 10 and on the other hand on the storage lever 9.
- the accumulator lever 9 is held in its functional position according to FIG. 9, even when the actuation of the actuating lever 4 ends.
- the further stop contour 12b on the shift lever 12, which has already been mentioned, may additionally ensure that the latching contours 9a, 10a are detached from one another.
- a (spring-assisted) resetting of the release lever 2 starting from the open position of the locking mechanism 1 according to FIG. 14 leads to a counterclockwise rotation of the release lever 2 about the axis 3.
- the switching lever 12 and thus also the storage lever 9 may be carried along via the stop contour 12b become.
