Description

lock assembly

The invention relates to a lock assembly, in particular for vehicle doors or vehicle doors, with a

Lock housing, a rotatably mounted on the lock housing rotary latch, which in a locking position for locking the

Vehicle door or vehicle door and an open position for

Release of the vehicle door or vehicle door is movable, and a pivotally mounted on the lock housing pawl, between a the catch in its locked position

locking position and releasing the catch releasing position is movable, wherein the pawl is formed in the blocking position a rotational movement of the catch in the direction of the open position blocking.

A lock arrangement of the type described is known for example from DE 10 2012 102 724 AI. This known lock assembly has a catch and a

Rotary latch in a detent position retaining pawl, wherein the catch and the pawl are rotatably mounted on a lock housing. During the closing process, a locking bolt engaging in the jaw of the catch ensures that the

Rotary latch is rotated from its open position into its detent position, wherein in this rotary motion, the catch with the

Pawl engages. In the locked position of

Rotary latch is then a movement of the catch in her

Open position only possible again when the pawl is moved from its blocking position to its release position, which is realized by means of a drive element provided for this purpose. In the detent position of the catch but can

Rotary catch in a beyond the detent position

Rotate Überhubsteilung, whereby a game is generated to the pawl and the catch can move relative to the locking pin, which is a perceptible to the user Rattling noise causes. In particular, in lock assemblies that are used in flat-mounted tailgates, the sealing forces are low, creating only a very little to no tension on the lock assembly of rotary latch and

Pawl acts whereby the catch is possible to rotate in the overstroke position described above, resulting in the described as well as unwanted rattling noise. For this reason, a solution is known in the known from DE 10 2012 102 724 AI lock assembly in which a rotatably mounted on the lock housing Ruhigstellungselement is provided which ensures that in locking position of the catch of the locking bolt between the rotary latch and the hebeiförmigen

Quenching element is clamped so that a relative movement of the locking bolt with respect to the catch, which is responsible for the disturbing rattling noise, is prevented. A disadvantage of this known lock arrangement is that for immobilizing an additional component is needed, which is reflected in higher production costs and in a reduced compactness of 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 is avoided and characterized by a compact design

out draws.

In a lock arrangement of the type described, this object is achieved in that the pawl is formed in the blocking position a rotational movement of the catch in a direction opposite to the open position blocking. The pawl thus blocks one

Rotational movement of the catch both in the direction of rotation of her

Open position as well as in the open position

opposite direction of rotation. Consequently, a rotational movement of the rotary latch in both directions of rotation alone by the

Locking pawl blocked. Advantageous and expedient embodiments and

Further developments of the invention will become apparent from the

Subclaims.

With the invention, a lock assembly is provided in a structurally simple manner and cost, which is characterized by a simple and compact design and yet effective rotational movement of the catch from their

Detent position out in both directions prevented when the pawl is arranged in its locked position. Characterized in that the pawl prevents rotation of the catch in a beyond the detent position Überhubsteilung at a time from which the pawl is arranged in its blocking position, the known from the prior art problem of unwanted rattling noise is effectively avoided. The invention is characterized by a purely mechanical solution, which, in contrast to known prior art lock arrangements without an additional component, such as

For example, a hoof-shaped immobilization element, and without any rubbery and wear-prone buffer elements manages.

The invention provides according to an advantageous embodiment, that at a longitudinal end of the pawl, a hook-shaped trained pawl portion is formed, which has a first locking surface, and that the rotary latch is a radial

having protruding locking element with a first contact surface, wherein in the blocking position, the pawl with her

Pawl portion of the locking element engages under the first contact surface and the pawl with the first locking surface on the first bearing surface at least partially so

is present that a rotational movement of the rotary latch is blocked in the direction of the open position.

A compact design of the lock assembly is ensured in a further embodiment of the invention in that the pawl is spaced from the first locking surface second Blocking surface, wherein the rotary latch has a second contact surface spaced from the first contact surface, and wherein in the blocking position, the pawl with the second

Blocking surface on the second bearing surface at least

partially abuts such that a rotational movement of the

Rotary latch is blocked in a direction opposite to the open position.

According to a first embodiment of the invention, it is particularly advantageous if the latching element of the rotary latch is designed as a radially projecting from the rotary latch and tooth-shaped projection and that the pawl portion of the pawl has a mouth-shaped and adapted to the tooth-shaped projection of the rotary latch recess, wherein in Locked position of the tooth-shaped projection of the rotary latch is at least partially disposed lying within the mouth-shaped recess of the pawl. The mouth-shaped pawl portion of the pawl and the tooth-shaped projection of the catch go in the blocking position of the pawl and in the locked position of the catch one

positive connection, by which both a movement of the catch in its open position and in one of

Open position opposite direction is blocked. In this case, the mouth-shaped recess is adapted to the tooth-shaped projection such that the functionality for both in

Lock position desired wedge effect as well as for easy release of catch and pawl when opening the

Vehicle flap is guaranteed.

It is structurally particularly favorable in the embodiment of the first embodiment, when the first contact surface and the second contact surface of the rotary latch facing away from each other

Side edges of the tooth-shaped projection are. Accordingly, the first blocking surface and the second blocking surface are aligned facing an interior of the mouth-shaped recess and arranged opposite one another and facing each other. The

Rotary latch and the pawl thus have a constructive simple shape, which can be produced inexpensively using known manufacturing processes.

According to the tooth-shaped approach and the

maulförmige recess matched to one another that in the locked position between the tooth-shaped projection and the

mouth-shaped recess a Keilverhakung occurs. As a result, wedged during travel of a motor vehicle, the pawl and the catch with each other, causing rattling

be prevented. With regard to the wedging action or

Wedge locking it is in design for the first

Embodiment particularly favorable when the first contact surface and the second contact surface in the direction of the pawl at a contact surface angle between 5 ° and 15 °

are arranged diverging from each other. With respect to the wedge effect, it is also favorable for the pawl when the first locking surface and the second locking surface are disposed in a direction away from the rotary latch at a locking surface angle diverging from each other, which is smaller than the predetermined contact surface angle for the rotary latch.

The invention provides a design for a second

Embodiment before that the first abutment surface of the second abutment surface is formed opposite, wherein the

Rotary latch has an investment recess, which is connected to the first

Abutment surface is disposed adjacent and formed, wherein the second abutment surface forms at least one wall portion of the investment recess.

For the second embodiment, it is provided in a further refinement that the contact recess has a contact contour which is coordinated with the hook-shaped catch portion

in the blocking position, at least in sections, the first blocking surface on the first contact surface and, at least in sections, the second blocking surface on the second

Abutment surface such that a rotational movement of the

Rotary latch in the direction of the open position and in one of Open position opposite direction, so one

Überhubsteilung, are blocked.

In terms of a sufficient wedge effect, it is in

Configuration of the second embodiment is advantageous if the first contact surface and the second contact surface are arranged in the direction of the pawl under a contact surface angle between 75 ° and 85 ° apart from each other.

For the first embodiment and for the second

Embodiment, it is particularly favorable in terms of functionality (wedge effect, but also a slight release of the catch and pawl upon opening of the vehicle door), when the first locking surface has a greater length than the second locking surface. This ensures that in

Lock position, the wedge effect is present and that

Slightly release the catch and the pawl if the catch should reach its open position. Equally favorable to the

Functional safety affects both in design

Embodiments of when the first abutment surface has a greater length than the second abutment surface.

For both embodiments, it is in terms of

Operability also advantageous if the first

Contact surface and the second contact surface in the direction of

Pawl are arranged under a contact surface angle diverging from each other. With respect to the pawl, it is also advantageous if the first locking surface and the second locking surface are arranged in a direction away from the rotary latch direction at a locking surface angle diverging from each other.

Thus, in the blocking position sufficient friction is present so that the wedging of pawl and rotary latch in the locked position does not solve and yet for a

Opening operation of the tailgate a release of the wedging is possible, the invention provides in an embodiment that in

Locked position, the first locking surface parallel to the first Contact surface is arranged, wherein the first locking surface and the second locking surface are designed to diverge in the direction of the rotary latch. Likewise, it is advantageous if, in the blocking position, the first blocking surface parallel to the first

Contact surface is arranged, wherein the distance between the first blocking surface and the second blocking surface increases in the direction of the rotary latch.

According to an alternative embodiment, it is conceivable that the first blocking surface is not designed parallel to the first contact surface, but that it is at least one of

Surfaces (blocking surface (s) and / or contact surface (s)) are surfaces designed in a radius, in which the radii of the surfaces (blocking surface (s) and / or abutment surface (s)) have the same radius, but the radii centers offset from each other lying, so that it is only a line touch of

Locking surface and contact surface comes. With the help of such an embodiment, the friction conditions between

Locking surface and contact surface are set. The offset of the radii centers also causes the pawl is always pulled by the rotary latch, which urges in the open position in the locked position.

In order to rotate the catch from its locking position to the open position, it is provided in an embodiment that the rotary latch is spring-biased in the direction of its open position. In this way, can be applied to a motor drive to move the

Rotary latch can be dispensed with.

At the same time, the invention provides in a further embodiment that the pawl is spring-loaded in the direction of its blocking position by means of a spring element. The

Spring element thus urges in the blocking position, the hook-shaped pawl portion of the pawl always in the direction of the rotary latch, so that the clamping action between the

Pawl portion of the pawl and the rotary latch is supported by the spring element. This is supported by a thigh of the spring element on the lock housing, whereas the other leg of the spring element, for example, on a

Ratchet lug of the pawl is applied.

It is understood that the above and

hereinafter to be explained features not only in the combination specified, but also in others

Combinations or alone, without departing from the scope of the present invention. The scope of the invention is defined only by the claims.

FIG. 2 shows a perspective view of the lock arrangement 3 shown merely by way of example in FIG. 1, whereas in FIG. 3 the lock arrangement is shown in a single part illustration. In FIGS. 4 to 11, for reasons of

Clarity on a representation of an apparent from Figures 2 and 3 lock housing 4 is omitted.

FIGS. 2 to 8 show a first embodiment of the invention, whereas FIGS. 9 to 11 show a second embodiment. The following

Description is valid for both embodiments, although only the first embodiment for certain components provides a detailed description. On the special

Differences between the two embodiments will be explicitly noted.

Figures 2 and 3 show the lock assembly 3, in which a not shown in the figures and fixedly arranged on the motor vehicle 1 locking bolt with a

Drehfallenmaul 5 a rotary latch 6 cooperates, in

Closed position of the lock assembly 3 of the locking pin is trapped in the rotary latch jaw 5 of the rotary latch 5 and the catch 5 is engaged with a pawl 7, so that the

Tailgate 2 is locked, whereas the tailgate 2

can be pivoted when the catch 5 and the

Pawl 7 are disengaged and the locking pin itself can move out of the rotary latch jaw 5 out. Of course, a reverse arrangement is conceivable in which the lock assembly 3 is fixedly fixed to the motor vehicle 1 and the locking bolt with the tailgate 2 is mitbewegbar.

Consequently, the lock assembly 3 according to the invention comprises the

Rotary latch 6, which is rotatable about an axis of rotation 8 at the

Lock housing 4 is mounted (see Figure 2). In Figure 2, the catch 6 is arranged in a detent position, which is a position for locking the vehicle door 2. Upon rotation about the axis of rotation 8 in the clockwise direction, the rotary latch 6 can be moved to an open position to release the locking pin and thus the vehicle door 2. The rotary latch 6 is spring-biased in the direction of its open position. This means that, for example, a spring exerts a force on the rotary latch 6 to urge the rotary latch 6 in the open position when the

Rotary latch 6 is arranged in the locking position. In this case, the pawl 7 holds the catch 6 in its locked position when the pawl 7 is arranged in a blocking position (see Figure 2). The pawl 7 is pivotally mounted on the lock housing 4 via a pivot axis 9 and between the locking position, in which the pawl 7 secures the catch 6 in its locked position, and a release position releasing the catch 6 movable. The pivot axis 9 itself is with the help of a

pivotally mounted on the lock housing 4 mounted movement element 10 movably mounted on the lock housing 4. At least when the pawl 7 is to assume its blocking position, a spring element 11 shown only in FIG

Pawl 7 and urges a free longitudinal end 14 of the

Pawl 7, which is designed as a hook-shaped

Pawl portion 12 is formed, in the direction of the rotary latch 6. The spring element 11 thus ensures that the pawl 7 is spring-loaded from its release position in the direction of its locking position by means of the spring element 11. A first leg IIa of the spring element 11 is supported on the Lock case 4, whereas a second leg IIb of the spring element 11 rests against a pawl pin 7a of the pawl and exerts on the pawl pin 7a acting in the direction of the rotary latch 7 force on the pawl 6.

The hook-shaped latch portion 12 has a first blocking surface 15. Furthermore, a radially protruding latching element 16 (see FIG. 2), which has a first contact surface 17, is formed on the rotary latch 6. By the first locking surface 15 is the pawl 7, when in the

Locking position is arranged, a rotational movement of the rotary latch 6 in the direction of the open position (see arrow 18 in Figure 4) blocking formed by the locking pawl 7 engages with its pawl portion 12, the locking element 16 on the first contact surface 17 and the pawl 7 with the first Locking surface 15 on the first bearing surface 17 at least

partially abuts such that a rotational movement of the rotary latch 6 is blocked in the direction of the open position. The first locking surface 15 and the first contact surface 17 are not completely in contact with each other in the locked position or detent position. Rather, the first blocking surface 15 rests, at least in sections, on the first contact surface 17, as shown for different states in FIGS. 6 to 8, wherein states are also conceivable in which the first contact surface 17 rests completely on the first blocking surface 15. As can be seen from the figures, the first blocking surface 15 is the

Pawl 7 with a greater length 19 formed as the length 29 of the first bearing surface 17 of the rotary latch 6. Further, the length 19 of the first locking surface 15 is formed larger than the length 20 of the second locking surface 21 (see Figure 5).

Finally, the length 29 of the first contact surface 17 is formed larger than the length 30 of the second contact surface 22 (see Figure 4).

Characteristic of the invention and for both

Embodiments it is that the pawl 7 in the Blocking a rotary movement of the rotary latch 6 in a direction opposite to the open position direction (see arrow 23 in Figure 4) is designed to block. For this purpose, the pawl 7 a spaced from the first locking surface 15 second

Locking surface 21, whereas the rotary latch 6 has a second bearing surface 22 spaced from the first contact surface 17. In this case, in the blocking position, the pawl 7 with the second blocking surface 21 at least partially on the second contact surface 22 such that a rotational movement of the

Rotary catch 6 in the opposite direction of the open position

23 is blocked.

With reference to the first embodiment of the invention, which is shown in Figures 2 to 8, the locking element 16 of the rotary latch 6 is formed as a radially projecting from the rotary latch 6 and tooth-shaped projection 24. The pawl portion 12 of the pawl 7 has in the first embodiment, a mouth-shaped recess 25 which on the tooth-shaped projection

24 of the catch 6 is tuned. Here, the tooth-shaped projection 24 of the rotary latch 6 is dimensioned such that upon movement of the pawl 7 from the release position in the

Lock position, the jaw-shaped recess 25 without friction and contact the tooth-shaped projection 24 of the catch 6 at least partially receives and surrounds and that upon movement of the pawl 7 from the locked position in the

Release position, the pawl 7 and the catch 7 slightly loose and disengage. In the

Locking position is the tooth-shaped projection 24 of the rotary latch 6 at least partially within the mouth-shaped recess

25 of the pawl 7 arranged lying. As can be seen from FIG. 4, the first abutment surface 17 and the second abutment surface 2 of the rotary catch 6 are facing away from one another

Side edges 24a and 24b of the tooth-shaped projection 24th

In contrast, the first blocking surface 15 and the second

Locking surface 21 to an interior 26 of the mouth-shaped recess 25 facing and arranged facing each other and facing each other, as shown in Figure 5.

It is also characteristic of the invention that a jamming between the tooth-shaped projection 24 of

Rotary latch 6 and the mouth-shaped recess 25 of the pawl 7 adjusts when the pawl 7 in its locked position

is arranged and the projection 24 is at least partially disposed lying in the recess 25. For then leads a minimal movement of the rotary latch 6, which is less than the given by the elastic flap seal movement tolerance, to a wedging of the tooth-shaped projection 24 in the

mouth-shaped recess 25, as shown in Figures 6 to 8 for different relative positions of the catch 6 to

Pawl 7 is shown. The jamming or wedging of projection 24 and recess 25, but also the release of this

Deadlock to release the tailgate 2 is thereby

favors that the first contact surface 17 and the second

Contact surface 22 in the direction of the pawl 7 under a

Abutment surface angle 27 between 5 ° and 15 ° apart from each other are arranged (see Figure 4). The contact surface angle 27 is preferably 10 °. Jamming or wedging of projection 24 and recess 25 is further facilitated if the first locking surface 15 and the second

Locking surface 21 in a direction away from the catch 6

Direction below a locking surface angle 28 are arranged diverging from each other. In this case, the locking surface angle 28 is smaller than the abutment surface angle 27 is formed. to

Illustrating the contact surface angle 27 and the

Locking surface angle 28, the respective dashed line, which marks the course of the first locking surface 15 and the first bearing surface 17, parallel to the dashed line, which indicates the course of the second locking surface 21 and the second contact surface 22. It is further provided that in the blocking position, the first locking surface 15 is arranged parallel to the first contact surface 17, wherein the first locking surface 15 and the second locking surface 21 are designed to be divergent in the direction of the rotary latch 6. This means that in the blocking position, the first blocking surface 15 is arranged parallel to the first contact surface 17, wherein the distance 50 between the first blocking surface 15 and the second blocking surface 21 in the direction of the rotary latch 6 increases.

In the figures 6, 7 and 8 states are shown, in which the pawl 7 is arranged in its locked position and the catch 6 is in its detent position. The above-described construction of the pawl portion 12 of the pawl

7 and the locking element 16 of the catch 6 provide at a force acting on the catch 6 force which is transmitted through the tailgate 2 on the locking pin on the catch 6 that the tooth-shaped projection 24 of the catch 6 in the mouth-shaped recess 25 of the pawl 7 so wedged or hooked that 2 rattling noises are prevented during the driving operation of the motor vehicle. The entanglement, which may also be referred to as jamming or wedging, is for the states shown in FIGS. 6 through 8

characterized in that in the blocking position both the first

Blocking surface 15 at least in sections at the first

Bearing surface 17 abuts and the second locking surface 21 at least in sections on the second bearing surface 22nd

is applied, so that both a rotational movement of the rotary latch 6 is blocked in the direction of the open position 18 and a

Rotary movement of the rotary latch 6 in the open position

opposite direction 23 is blocked. By the

described wedge action or wedge locking is ensured that the catch 6 in the locked position of the catch 6 and in the blocking position of the pawl 7 not at all about the axis of rotation

8 can turn. Figs. 9 to 11 show a second embodiment of the present invention. The second embodiment differs from the first embodiment by an alternative

Embodiment of rotary latch 6 'and pawl 7', which will be discussed below. In the second embodiment, in the case of the rotary latch 6 ', the first contact surface 17' of the second contact surface 22 'is formed opposite. The rotary latch 6 'in this case has an investment recess 31 which is connected to the first

Bearing surface 17 'is formed adjacent. Furthermore, the second contact surface 22 'forms at least one wall section of the

Investment recess 31, as can be seen in particular in FIG. The first blocking surface 15 'is arranged facing away from the second blocking surface 21'. The first blocking surface 15 'and the second blocking surface 21' are in a direction away from the rotary catch 7 'under the blocking surface angle 28

arranged diverging from each other. Furthermore, the first contact surface 17 'and the second contact surface 22' in the direction of the pawl 7 'under a contact surface angle 27, which is between 75 ° and 85 °, arranged diverging from each other, wherein the contact surface angle 27 is greater than that

Locking surface angle 28. Unlike the first

Embodiment, in the second embodiment, the first locking surface 15 'has a smaller length 19 than the second

Locking surface 21 ', which is not absolutely necessary, because the second locking surface 21' only has to have a length with which it can at least partially rest against the second contact surface 22 '. Consequently, the first blocking surface 15 'may alternatively have a greater length 19 than the second blocking surface 21'. By contrast, also in the second embodiment, the first contact surface 17 'has a greater length 29 than the second contact surface 22'. Like from the

Viewing together of Figures 10 and 11 shows, further, the investment recess 31 has a hook-shaped

Pawl section 12 tuned contact contour 32. These In the blocking position, the first blocking surface 15 'abuts, at least in sections, on the first contact surface 17' and the second blocking surface 21 'at least partially against the second contact surface 22', so that a rotational movement of the rotary latch 6 'both in the direction of the open position and is blocked in a direction opposite to the open position. In the second embodiment, the locking surface angle is smaller than 28 as in the first embodiment

Contact surface angle 27 formed, as shown in Figures 10 and 11 can be seen. The operation of the second

Embodiment is identical and is carried out according to the identical Verklemmungsprinzip by the first in blocking position

Locking surface 15 'at least in sections at the first

Bearing surface 17 'is applied and the second locking surface 21'

at least in sections on the second contact surface 22 'is applied, so that reference is made with respect to the principles of the invention to the comments on the first embodiment.

According to a first embodiment, the

Invention on a lock assembly 3 for a vehicle door 2. The lock assembly comprises the lock housing 4, the rotary latch 6 rotatably mounted on the lock housing 4 and the pawl 7 pivotally mounted on the lock housing 4

Pawl 7 has the mouth-shaped recess 25 which receives the tooth-shaped projection 24 of the catch 6 in the blocking position at least in sections such that both the first blocking surface 15 at least partially at the first

is applied. The sectional concerns of the locking surfaces 15, 21 on the contact surfaces 17, 22 establishes a positive connection between the pawl 7 and the rotary latch 6, so that both a rotational movement of the rotary latch 6 is blocked in the direction of the open position 18 and a rotational movement of the Rotary catch 6 is blocked in the direction opposite to the open position 23.

Of course, the invention described above is not limited to the described and illustrated embodiments. It can be seen that many of the embodiments shown in the drawing, the expert

according to the intended application obvious
