Description

The invention relates to a lock arrangement, in particular for vehicle doors or vehicle doors, preferably for a tailgate. The lock assembly of the type in question has a lock housing on which a rotary latch is rotatably mounted, which is movable at least between an open position and a main latching position. Further, the lock assembly on a pivotally mounted on the lock housing pawl which is movable between a locking position in engagement with the locking position and a release position.

A lock assembly of the type described is, for example, from the DE 10 2013 113 384 A1 known. In this known lock arrangement, the pawl by means of a control element, which comprises a gear and is in driving connection with a motor drive, moved from the blocking position in the direction of the release position to release the catch for opening the vehicle door or vehicle door. The control element is moved by the motor drive, wherein the drive after opening the vehicle door or vehicle door also ensures that the control element for a new opening operation is moved back to its original position. During the closing process, a locking bolt engaging in the jaw of the rotary latch ensures that the rotary latch is rotated from its open position into its main locking position, with the rotary latch engaging the locking pawl during this rotary movement. In the main locking position of the rotary latch, a movement of the rotary latch into its open position is then only possible again when the locking pawl is moved from its locking position into its release position, which is realized by the control element described above. In the main position of the catch, however, the catch in rotate over the main latching position overstroke position, whereby a game is generated to the pawl and the catch can move relative to the latch bolt, causing a perceivable rattling noise for the user. In particular, in lock assemblies that are used in flat-mounted tailgates, the sealing forces are low, whereby only a very little to no tension on the lock assembly of catch and pawl acts whereby the catch is possible to rotate in the above-described overstroke position, which leads to the described as well as unwanted rattle noise. For this reason, known from the prior art, a solution in which the mouth of the rotary latch is provided with rubber-like buffers to reduce unwanted rattling noise due to the relative movement between the locking pin and rotary latch. However, such bumpers wear quite heavily and moreover increase the force required to be used to close the lock assembly.

The invention has for its object to develop a lock assembly in a structurally simple manner and cost, in which an undesirable noise due to a relative movement between the catch and latch bolt is effectively avoided. In particular, a solution is to be created by the rotational movement of the catch is avoided in an overstroke after the catch and the pawl are already locked.

The object is achieved in that a pivotally mounted blocking lever is arranged on the lock housing, which is pivotable between a standby position and a blocking position. Preferably, the blocking lever is rotatably arranged on the lock housing. In the ready position, the blocking lever is without engagement with the rotary latch. This preferably means that the catch is rotatable about an entire constructively permitted angle of rotation, without the catch touching the lock lever in the ready position. The blocking lever is pivotally mounted from the standby position to a blocking position on the lock housing. After pivoting into the blocking position, a blocking surface of the blocking lever is positioned relative to the main catch position in the rotary latch, that the blocking lever at least then comes into operative connection with a locking counter surface of the rotary latch when the catch is in its main latching position and in this constellation in addition to a Over-stroke position of the rotary latch acting torque acts on the rotary latch. In particular, it can be provided that the blocking surface of the blocking lever prevents the locking counter surface of the rotary latch on a rotary movement of the rotary latch beyond its Hauptastaststellung addition into an overstroke position by blocking the catch, so it is in the way. At least, however, rotation of the rotary latch via the main latching position is largely limited by the latching lever in the blocking position.

Furthermore, the invention provides that an at least translationally guided release member is arranged on the lock housing, which is movably guided at least between a non-triggering position and a release position, wherein over one or both of said positions beyond possible leadership must not be excluded.

The blocking lever is spring biased towards its blocking position, so he seeks at least from its standby position in the direction of the blocking position. The trigger member is biased to its non-triggering position, so it strives at least from its triggering position to its non-triggering position. In its non-release position, the trigger member blocks the blocking lever, so that it is prevented from making a pivoting movement from the ready position in the direction of the blocking position.

In other words, so trigger member and locking lever are formed and positioned relative to each other that the blocking lever in its non-triggering position, to which he yes - if he is not hindered - strives, the blocking lever provides an obstacle, with which the blocking lever on the movement is prevented in the direction of its spring bias.

Advantageous and expedient refinements and developments of the invention will become apparent from the dependent claims.

The invention provides a lock assembly in a structurally simple manner and cost, which is characterized by a simple structure and yet effective prevents rotation of the catch from its main latching position in a so-called overstroke position, if or after the pawl has reached its blocking position and the blocking lever has taken its blocking position after bringing about the closing. Characterized in that a rotational movement of the rotary latch is prevented or at least limited in a beyond the main latching position overstroke position in the sequence, the known from practice problem of unwanted rattling noise is effectively avoided. The invention is characterized by a purely mechanical solution, which manages in practice, unlike known lock arrangements without any rubbery and wear-prone buffer elements. Due to the fact that the catch due to the blocking of the catch by the blocking lever - depending on the design of the lock assembly - can not reach or at most slightly in an overstroke position, the advantage is further achieved that even with jerky closing of the lock, such as by throwing a vehicle door, at which the lock is arranged, a hard stop of the vehicle door or its seal is avoided.

The invention thus has the advantage already explained in detail above that, by providing a blocking lever, a movement of the rotary catch into an overstroke position by the blocking lever is prevented. The fact that a trigger member and a locking lever in the illustrated spring-biased configuration are arranged oriented to each other on the lock housing is to release the locking lever for avoiding movement of the rotary latch in an overstroke position provided a favorable and structurally elegant solution, with the blocking of Rotary latch to avoid the assumption of an overstroke effectively and easily to the corresponding concretely present conditions, such as the space provided, customizable manner is implemented.

The trigger member is preferably formed in one piece, but it is also not excluded that multi-part release members are used.

According to an advantageous embodiment, the trigger member is designed such that upon movement of the trigger member against a contact force which biases the trigger member in the non-triggering position, upon reaching the triggering position, the trigger member releases the pivotal movement of the blocking lever in the blocking position. In this embodiment, the blocking of the blocking lever by the trigger member is thus brought about by moving the trigger member against its contact force.

In order to cancel the blockage of the blocking lever by the trigger member, a counter-member is provided in a preferred embodiment, which is arranged on the rotary latch. The counter-member is positioned on the rotary latch such that when the rotary latch is rotated in the direction of rotation from the open position to the main-latching position, the counter-member is operatively connected to an end-side contact surface of the triggering member. After the active compound occurs, the continued rotation of the Rotary catch in the direction of rotation of the open position in the main latching position entrainment of the trigger member against its contact force in the direction of the release position.

It is particularly preferred if the counter-member is designed as a bolt and is positioned such that the entrainment of the trigger member takes place by the bolt pushes the trigger member against its contact force, according to the leadership of the trigger member by a guide means of the lock assembly. In an elegant embodiment, the bolt is oriented parallel to the axis of rotation of the rotary latch. Furthermore, embodiments may be provided in which the counterpart is formed integrally with the rotary latch, whereby manufacturing costs can be saved.

A preferred constructional solution, which converts the intended avoidance of a movement of the blocking lever to its blocking position, provides a retaining formation arranged or formed on the blocking lever and a holding extension arranged on the triggering member. Halteausformung and holding extension are formed and positioned relative to each other, that the retaining shape of the blocking lever, at least when the trigger member is in its non-triggering position, is in operative connection with a holding surface of the holding extension. By the operative connection of the blocking lever is prevented from pivoting from its standby position to its blocking position. For example, the operative connection may be implemented as a blockage of the holding formation by the holding surface, as a result of which the holding formation, and with this also the blocking lever, is prevented from rotating in the direction of rotation from the ready position to the blocking position of the blocking lever.

According to a preferred embodiment, the holding extension is locally tapered along a portion of its longitudinal extent. The rejuvenation is parallel to the Blocking lever pivot axis of the blocking lever provided and includes a portion of the holding extension, which moves in the release position to the position of the holding surface in the non-release position. As a result, when the release member is moved into the release position, the operative connection between the retaining formation and the retaining extension is released. It is preferably provided that the holding formation is dimensioned in a direction parallel to the blocking lever pivot axis such that the holding formation can slide past it in the tapered region of the holding extension. The blockage of Halteausformung and thereby the blocking lever is thus canceled and released pivoting of the blocking lever in its blocking position. The taper of the holding extension is preferably dimensioned such that the operative connection between the holding formation and the holding extension is resolved upon reaching the release position by the trigger member.

It is preferably provided that the action of the rotary latch on the trigger member is adapted such that the trigger member reaches the triggering position in a position in which the rotary latch assumes an overstroke position beyond the main latching position. In other words, only a first over-rotation of the rotary latch beyond the main latching position in an overstroke position results in (for example by means of the counter-member) the triggering member being pressed up to its release position.

In a further development, the catch and blocking lever are formed and positioned relative to each other, that the blocking lever pivots in the blocking position due to the spring bias when in overstroke rotary latch in the direction blocking position stores before reaching its blocking position on a lateral surface of the still located in the over-stroke rotary latch. Only after turning back the catch in the skin-locking position, the blocking lever enters a recess of the catch and takes his blocking position. From the moment of taking the blocking position by the blocking lever a renewed movement of the rotary latch is prevented in an overstroke position due to the operative connection between locking surface and barrier counter-surface or at least limited. A movement of the catch is thus blocked in both possible directions of rotation. By placing the locking lever on a lateral surface of the rotary latch is achieved that damage to the locking lever is avoided in too early incidence of the locking lever in the exception of the catch. Due to the fact that the blocking lever only enters the exception of the rotary latch when the rotary latch is turned back in the direction of its main latching position and assumes its blocking position there, the transmission of force peaks to mechanical components connected to the rotary latch, such as, for example, to a cable pull actuator coupled to the rotary latch, avoided or reduced.

In order to accomplish the return movement of the blocking lever from its blocking position without additional components, according to an advantageous embodiment, a radially extending from the axis of rotation of the rotary latch stop element is arranged on the rotary latch. Stop element and locking lever are formed so adapted to each other and positioned relative to each other, that upon rotation of the catch from the main latching position into the open position, the stop element presses the blocking lever in the direction of its ready position. Preferably, the stop element is an integral part of the rotary latch, whereby reduced manufacturing costs and advantageous mechanical stability of the rotary latch can be achieved.

For a space-saving design of the lock assembly, a guide element is preferably arranged to guide the trigger member on the lock housing, which comprises the blocking lever pivot axis rotationally symmetrical. To be translationally guided by the guide element, can the trigger member having a slot and / or a long groove with rectilinear central axis which are coupled to the guide element and are guided by this.

Preferably, the trigger member is translationally guided to ensure the most compact design of the lock assembly. But it can also be provided an additional rotational movement component.

It is understood that the features mentioned above and those yet to be explained can be used not only in the respectively indicated combination but also in other combinations or in isolation, without departing from the scope of the present invention. The scope of the invention is defined only by the claims.

Further details, features and advantages of the subject matter of the invention will become apparent from the following description taken in conjunction with the drawing, in which an exemplary preferred embodiment of the invention is shown.

Show it:

• Figs. 1 to 8 : An exemplary embodiment of the already explained above variant of the lock assembly according to the invention in different stages of a sequence of movements.

In Fig. 1 an embodiment of the lock assembly 1 according to the invention is shown. It is a lock housing 2 shown, for reasons of clarity, however, only partially. On the lock housing 2, a rotatably mounted rotary latch 4 is arranged, which is spring-biased in the direction of rotation R. Further, a pivotally mounted pawl 5 is arranged on the lock housing. In the presentation of the Fig. 1 the rotary latch 4 is shown shortly before reaching its main locking position, which can be reached by correspondingly slight further rotation of the rotary latch 4 counterclockwise (based on the paper plane of the illustration shown). The pawl 5 is still in its release position and is due to a corresponding preload with their Bearing surface pressed against a lateral surface of the rotary latch 3. On the lock housing 2, a blocking lever 7 is also arranged, which is rotatably mounted and whose locking lever pivot axis 6 designed as a rotation axis with the axis of rotation of the guide member 17 is identical. The blocking lever 7 is located in one of its two extreme positions, namely in the so-called readiness position. In the standby position, the blocking lever 7 is removed as far as possible from the rotary latch 4 and there is no interaction with the rotary latch 4. The blocking lever is spring biased to make a rotational movement in the direction of the arrow F. However, a movement of the blocking lever in the direction of the arrow F is prevented by a trigger member 10, which prevents the movement of the blocking lever 7 in the direction of its blocking position by mechanical blockade.

The aforementioned trigger member 10 is also arranged on the lock housing 2. For this purpose, the trigger member 10 has a slot 18 which is guided in translation by a guide element 17 designed as a bolt, that is, at least translationally movable. The trigger member 10 is located in the illustration shown in one of its two possible end positions, which coincides in the illustrated embodiment with the non-triggering position. The trigger member is spring-biased to move from its trip position towards the non-trip position. The direction of the spring preload is shown by the arrow K. In its non-release position, a holding extension 15 arranged on the trigger member 10 is positioned such that a holding surface 14 of the holding extension 15 prevents movement of the blocking lever 7 in the direction of its biasing force by the holding surface 14 blocking the movement of the holding formation 13 of the blocking lever 7. In principle, the holding extension 15 can be positioned at any position of the blocking lever 7; It is essential that a pertinent Operational connection is present that a movement of the blocking lever 7 is prevented in the direction of its blocking position, as long as it is not released by moving the trigger member 10 to its release position.

In Fig. 2 is in a detailed presentation of the situation Fig. 1 illustrates how by suitable design of the trigger member 10, the movement of the blocking lever 7 is prevented in the direction of its blocking position. In the presentation of the Fig. 2 is omitted, inter alia, on the presentation of the lock housing 2. The perspective of Fig. 2 corresponds to a consideration of the back of the representation of Fig. 1 , It can be seen holding the formation 13, which extends radially from the axis of rotation 6 of the blocking lever 7, wherein the holding formation 13 and the locking surface 8 are positioned at two mutually remote ends of the blocking lever 7. Further, a holding extension 15 can be removed, which extends in a direction parallel to the blocking lever pivot axis 6 direction to a position plane of the blocking lever out and thereby provides a holding surface 14. The holding surface 14 is formed with the holding Ausformung 13 of the blocking lever so coordinated and positioned relative to each other, that at least when the trigger member 10 is in its non-triggering position, an operative connection between Halteausformung 13 and support surface 14, which is a pivoting of the locking lever 7 to his Blocking position prevented.

A movement of the blocking lever 7 to its blocking position is inhibited, since the holding surface 14 of the holding extension 15 blocks the movement of the holding formation 13 in the direction of rotation, which corresponds to a movement of the blocking lever 7 to its blocking position. A rotational movement of the due to its corresponding spring bias actually aspiring in the direction of the blocking position blocking lever 7 to its blocking position is thus prevented.

Fig. 3 differs from Fig. 1 in that the catch 4 is opposite to the one in FIG Fig. 3 shown position was moved in the direction of its main latching position. In the Fig. 3 The illustration shown corresponds to this main position. In the main locking position, the pawl 5 is immersed in a locking recess 19 of the rotary latch 4. A blocking surface 20 of the pawl 5 is connected to a locking counter surface 21 of the rotary latch 4 in operative connection and prevents turning back of the rotary latch in the direction of its open position. Upon rotation of the rotary latch 4 in the direction of the main latching position, a counter-member 11 designed as a bolt, which is coupled to the rotary latch 4, has come into operative connection with an end-side contact surface 12 of the triggering member 10. By continued rotation of the rotary latch 4 in the direction of rotation, in which the catch has also reached the main latching position from the open position, the trigger member 10 is pressed against its pointing in the direction K contact force to its release position and thereby moved translationally.

If starting from the in Fig. 3 The main catch position of the rotary latch 4 shown the catch 4 moves in the direction of rotation from the open position to the main latching position of the rotary latch 4, the catch is when the main latching position of the catch 4 is overcome, in a so-called overstroke position, such as in Fig. 4 a is shown. The overstroke position can be characterized, inter alia, by the fact that the pawl 5 is no longer in contact with the counter-locking surface of the rotary catch 4. As a result of the further rotation of the rotary latch 4 beyond the main latching position into an overstroke position, the triggering member is further moved counter to its biasing force acting in the direction K until the triggering member 10 reaches its triggering position as a result of its translatory movement. The release position is not in the illustrated example with an end position when moving between the two existing ends of the slot 18th identical. As Fig. 4b can be seen, a portion of the holding extension 15 of the trigger member 10 is moved in the release position against the biasing force, which is parallel to the blocking lever pivot axis 6 with respect to the support surface 14 having tapered region. The tapered region is positioned relative to the holding formation such that the holding formation 13 can now slide past the holding extension 15. A rotational movement of the blocking lever 7 in the direction of F due to its spring bias, ie to the blocking position of the blocking lever, is then released. From the representation of Fig. 4a shows that the rotary latch is dimensioned such that when the pin 11 pushes the trigger member in the release position, the blocking lever 7 is blocked when pivoting in the direction of its blocking position of a peripheral surface of the rotary latch 4 and the blocking lever is initially on the lateral surface of the rotary latch 4 stores.

Upon retraction of the rotary latch 4 from the overstroke position to its main latch position, as in Fig. 5 shown, the blocking lever 7 then immersed in a recess of the rotary latch 4, in which the blocking lever 7 can assume its blocking position and can enter with its blocking surface 8 in operative connection with the locking counter surface 9 of the rotary latch 4. In this position, the blocking surface 8 blocked by their positioning relative to the barrier counter-surface 9 a renewed rotational movement of the rotary latch 4 beyond the main latching position in an overstroke position. In the in Fig. 5 A rotation of the rotary latch 4 from the main latching position to the open position is prevented by the locking pawl 5 located in the blocking position and rotation of the rotary latch in an overstroke position is ensured by the blocking surface 8 provided the blocking lever 7 prevents which absorbs a force effecting a corresponding rotational movement.

Opening the lock by turning the catch to an open position is only after swinging out of the pawl 5 from the locking recess of the catch 4 out, so after releasing the locking, possible. The release of the locking can be done for example by an actuator or mechanically, the actual mechanism used for this purpose for the present invention is immaterial. The same applies to the rotation of the rotary latch, which is preferably brought about with an actuator, but can also be accomplished otherwise.

Upon rotation of the rotary latch 4 from the main latching position in the direction of its open position of the blocking lever 7 is moved due to a suitable shape of the rotary latch 4 again in the direction of its standby position. In order to provide the force required for this purpose against the biasing force of the blocking lever, the rotary latch 4 has a stop element 16 which extends radially from the axis of rotation 3 of the rotary latch. The positioning and the shape of the stopper member 16 is selected taking into account the exact geometric configuration and positioning of the blocking lever 7 such that upon rotation of the catch from the main latching position in the direction of the open position, the stopper member 16 enters into force with the blocking lever 7 and the blocking lever. 7 in this case continued rotation of the rotary latch 4 against its spring bias in the direction of its standby position, preferably up to the standby position, presses.

In order to illustrate the pressing of the blocking lever 7 in its standby position, is in Fig. 7 the same position of the explained movement as in Fig. 6 shown, however, for better visibility of the stop member 16, the locking lever 7 and the pressing of the Stop element 16 against the blocking lever 7 without showing the trigger member 10th

In Fig. 8 is shown that may be provided in an alternative embodiment, that the design and arrangement of rotary latch 4, counter member 11, trigger member 10 and blocking lever 7 can also be adapted to each other so that when reaching the main latching position and immediately before entering the pawl in the locking recess already the trigger member has reached its release position and the blocking lever 7 assumes its blocking position.
