Definitions
- Motor vehicle lock in particular motor vehicle door lock
- the invention relates to a motor vehicle lock, in particular a motor vehicle door lock, with a locking mechanism consisting essentially of a rotary latch and a pawl, and with an actuating lever chain working on the locking mechanism with a clutch lever, the clutch lever closing the actuating lever chain in the engaged state to act on the locking mechanism and in when the clutch is disengaged, and the clutch lever engages with a pin in a link of a positioning lever that guides it to change between these two stable end positions.
- Motor vehicle locks and in particular motor vehicle door locks of the conventional design according to the previously explained type have, for example, a clutch lever which is pivotally accommodated about an axis in or on an actuating lever becomes.
- the clutch lever has a control cam or link into which the clutch lever can engage with a pin.
- the actuating lever supporting the clutch lever can work on a release lever and, through the actuating lever chain closed in this way, lift the pawl from its engagement with the rotary latch in the closed position of the locking mechanism. In this way, the associated motor vehicle lock or its lock is opened.
- the clutch lever In addition to this engaged state of the clutch lever and the associated stable end position, it is also possible for the clutch lever to be pivoted relative to the actuating lever in such a way that the clutch lever does not move when the actuating lever is acted upon can be brought into engagement with the release lever. In this case, the clutch lever assumes its disengaged state as further second stable end positions.
- the previously mentioned control cam or link is provided on a control lever in the prior art.
- a comparable prior art which also describes a generic motor vehicle lock, is the subject of DE 10 2019 127 109 A1.
- a clutch lever is again implemented, which is guided using a link.
- the clutch lever has a pin that engages in the link.
- the backdrop is provided in or on an adjusting lever.
- the lever chain can be moved into a closing operating position using an emergency operating lever using an electric motor drive.
- the state of the art has basically proven itself. However, due to the sometimes complex movement of the clutch lever with its pin inside the link, malfunctions or even malfunctions are possible.
- the invention aims to provide a remedy here overall.
- the invention is based on the technical problem of further developing such a motor vehicle lock and in particular a motor vehicle door lock in such a way that functional reliability is increased and malfunctions are avoided.
- the invention proposes in a generic motor vehicle lock and in particular a motor vehicle door lock that the link implemented on or in the positioning lever is designed as a two-way link in such a way that the pin is moved along a first path by acting on the clutch lever reaches its first end position and after the clutch lever is acted upon again along a second, separate path.
- the two end positions i.e. H. the first end position and the second end positions correspond to the engaged or disengaged state of the clutch lever. Both end positions are assumed to be stable. Due to the different ways of taking the respective end position, any malfunctions are fundamentally avoided, in contrast to the prior art.
- the design is further made in such a way that the two-way link has at least one separating stop that separates the two ways from one another. Usually two separating stops are implemented. In addition to the separation stop, an evasive stop is provided.
- the interaction between the evasive stop and the separating stop ensures that the first path and the second path are spatially and functionally separated from one another and that the first end positions and the second end position are assumed in a stable manner and without mutual influence.
- two separating stops and one escape stop are provided inside the link according to the invention.
- the positioning lever carrying the link is equipped with a center-zero spring.
- the center-zero spring ensures that the link or the positioning lever has and assumes a basic position, from which pivoting movements of the positioning lever and thus also pivoting movements of the link carried by the positioning lever take place against spring force and the center-zero Spring ensures a reset starting from this basic position.
- the center-zero spring can advantageously be designed as a leg spring arranged on a bearing pin of the positioning lever with a winding section and two legs extending from it. The procedure is usually such that the winding section encloses the bearing pin and the two legs are each arranged on the edge of the positioning lever or act on it.
- the usual procedure is to assign a return spring to the clutch lever.
- the return spring ensures that the clutch lever is pretensioned or reset, comparable to the link, towards a basic position assumed by the clutch lever as well as the link. To now move the clutch lever, the force of the return spring assigned to the clutch lever must be overcome.
- the clutch lever is equipped with at least two arms, a pin arm carrying the pin and an additional clutch arm.
- the operating lever chain can be closed when the clutch lever is engaged and opened when the clutch is disengaged.
- the clutch lever may be mounted on an actuating lever and, in the engaged state, when the actuating lever is acted upon, take along a release lever, which in turn lifts the pawl from its latching engagement with the rotary latch.
- the disengaged state of the clutch lever corresponds to the fact that when the actuating lever is acted upon by the clutch lever mounted thereon, it becomes empty compared to the release lever, so that the actuating lever chain is mechanically interrupted in this case and the locking mechanism consisting of the rotary latch and pawl in the closed state cannot be opened.
- the previously described clutch arm which in the example case ensures the mechanical connection from the actuating lever to the release lever, and the pin arm of the clutch lever carrying the pin are typically spaced apart and in particular arranged at an angular distance from one another. In fact, it has proven useful if the coupling arm and the pin arm are mounted so that they can rotate about a common axis.
- the clutch lever is usually also equipped with an actuation arm.
- the actuating arm, the pin arm and the clutch arm have the common axis for rotating the clutch lever.
- the clutch lever can be actuated via the actuating arm. This allows the clutch lever - as described - to be guided between the two stable end positions with its pin within the link.
- the action on the clutch lever via its actuating arm can be realized and implemented in any way.
- the clutch lever is actuated manually via the actuating arm.
- Direct manual application has proven to be beneficial here.
- the actuating arm is acted upon indirectly or directly, for example via a locking cylinder.
- the clutch lever is acted upon and thus actuated via the clutch arm using an electric motor drive.
- the electric motor drive can take on a multiple function in such a way that with its help the clutch lever is not only engaged and disengaged, but also an electric motor opening is possible.
- the electric motor drive can in principle also open the locking mechanism in question by electric motor, as is the case in the generic prior art according to DE 10 2019 133 654 A1 is described in detail.
- the design of the backdrop according to the invention ensures that it is a two-way backdrop with the first path and the second path separated from it and the two reached via this stable end positions for a particularly functional structure, which at the same time prevents any malfunctions. This is where the main advantages can be seen.
- FIG. 1 to 6 show the motor vehicle lock according to the invention during the transition of the clutch lever from its basic position shown in FIG. 1 to the first end position in the illustration according to FIG. 6 along a first path and
- the figures show a motor vehicle lock, which is a motor vehicle door lock. This is reduced to its essential elements for the invention.
- the motor vehicle lock or motor vehicle door lock has a locking mechanism 1, 2 consisting of a rotary latch 1 and a pawl 2, which is only indicated in FIG 5.
- the release lever 4 and the clutch lever 5 overall define an actuating lever chain 4, 5, with the help of which the locking mechanism 1, 2 shown in FIG. 1 can be opened.
- an opening movement of the locking mechanism 1, 2 shown in the closed state in FIG. 1 corresponds to the fact that the clutch lever 5 is not only in its engaged state shown in dash-dotted lines in FIG. but also carries out a pivoting movement in the counterclockwise direction about its axis 6, which is also indicated in FIG.
- the clutch lever 5 may be mounted on an actuating lever, not shown.
- the engaged state of the clutch lever 5 corresponding to the dash-dotted representation in FIG works and can also work with its clutch arm 5a on the release lever 4, which in turn acts on the pawl 2.
- the pawl 2 pivots about its axis in the counterclockwise direction and releases the rotary latch 1, which was previously rusted with the pawl 2 in the closed position of the locking mechanism 1, 2.
- the rotary latch 1 can then swing open in the clockwise direction indicated in FIG. 1 and in turn releases the locking bolt 3 and thus an associated motor vehicle door.
- the overall design is such that the operating lever chain 4, 5 working on the locking mechanism 1, 2 is equipped with the previously mentioned clutch lever 5.
- the clutch lever 5, in its engaged state shown in dash-dotted lines in FIG. 1, ensures that the actuating lever chain 4, 5 is closed to act on the locking mechanism 1, 2.
- the disengaged state of the clutch lever 5 shown in solid lines in FIG. 1 and assumed in FIG. 1 means that the actuating lever chain 4, 5 is opened.
- the clutch lever 5 engages with a pin 7 in a link 8 guiding it, ie the clutch lever 5, to change between these two stable end positions.
- the link 8 is provided on a positioning lever 9.
- the positioning lever 9 is only shown schematically and can be pivoted about an axis 10 according to the exemplary embodiment.
- the positioning lever 9 may be an adjusting lever, as is also provided in comparable motor vehicle locks and in particular in the generic prior art according to DE 10 2019 133 654 A1.
- link 8 on or in the positioning lever 9 is designed as a two-way link 8 according to the exemplary embodiment.
- the pin 7 on the clutch lever 5 can cover a first path 11 within the link 8 until it reaches the first end position of the pin 7 in the functional position according to Fig. 6.
- the pin 7 is able to complete a second path 12, starting from the first end position as shown in Fig. 6 up to the second end position as shown in Fig. 10 and in the same way in the basic position according to Fig. 1.
- the second end position according to Fig. 1 or 10 may belong to the “secured” position of a safety device, which accordingly corresponds to the “disengaged” state of the clutch lever 5.
- the first end position in the functional position according to Fig. 6 represents the "unlocked” state of the safety device and accordingly the "engaged” state of the coupling lever 5.
- the safety device may be a locking device, a child safety device, an anti-theft device or even combinations.
- the link 8 is not only designed as a two-way link 8, but also in such a way that when the clutch lever 5 is acted upon Pin 7 reaches the first end position in FIG. 1 passes. Both paths 11, 12 are spatially and functionally separated from each other.
- the two-way backdrop 8 is equipped with a separating stop 81 that separates the two paths 11, 12 from each other.
- two separating stops 81, 82 are provided. In addition to the two separating stops 81, 82, you can also see an evasive stop 83.
- the two separating stops 81, 82 are found on both sides of the escape stop 83, which is provided opposite a recess formed between the two separating stops 81, 82, into which the pin 7 dips at the end of the first path 11 and in the first end position according to FIG. 6 is held in contact with the separating stop 82.
- the positioning lever 9 is equipped with a center-zero spring 13, which is only indicated, which according to the exemplary embodiment may be designed as a leg spring, which with its winding section encloses a bearing pin defining the axis 10 and has two legs extending from the winding section.
- the clutch lever 5 is in turn equipped with a return spring 14, which ensures that the clutch lever 5 returns to its basic position shown in FIGS. 1 and 10 or the second stable end position (“secured” by the safety device and “disengaged” by the clutch lever 5). is transferred.
- the clutch lever 5 is additionally equipped with a pin arm 5b carrying the pin 7 in addition to the clutch arm 5a already mentioned.
- an actuating arm 5c is usually provided.
- the three previously mentioned arms 5a, 5b and 5c of the clutch lever 5 are rotatably connected to the common axis 6.
- the three arms 5a, 5b and 5c each define the clutch lever 5 at an (angular) distance from one another.
- the positioning lever 9 together with the link 8 has been pivoted counterclockwise about the axis 10, so that As a result, the center-zero spring 13 has been deflected. After reaching the functional position in FIG. 3, the center-zero spring 13 ensures that the positioning lever 9 and with it the link 8 are reset in the counterclockwise direction, as can be seen from a transition from FIG. 3 to FIG can. Now the pin 7 rests against the avoidance stop 83.
- the associated actuating arm 5c may be operated manually or with an electric motor drive, as explained in the description instructions. That is, comparable to the ballpoint pen principle already described, a renewed application in the same direction of the clutch lever 5 ensures that the previously achieved locking or reaching the first end position in the illustration according to FIG. 6 after completing the first path 11 is canceled by the pin 7 and can also be canceled.
- the action of the clutch lever 5 on its actuating arm 5c in a counterclockwise direction about its axis 6 during the transition from FIG. 6 to FIG. 7 now results in the pin 7 being able to leave the lower separating stop 82.
- the center-zero spring 13 is able to act on the positioning lever 9 about its axis 10 in a counterclockwise direction, so that the pin 7 changes from the functional position according to FIG. 7 to the position according to FIG. 8.
- the positioning lever 9 can be reset again using the center-zero spring 13, which corresponds to the positioning lever 9 and with it the link 8 around the associated one Pivot axis 10 counterclockwise, as can be seen in the transition from Fig. 9 to
