Description

DETAILED DESCRIPTION OF THE INVENTION

[0001] The present invention is directed to a locking device as defined in the preamble of claim 1. In addition to the device located at the rear of the vehicle, there is another locking device with its own locking member at the door of the vehicle. To enable the various devices to be controlled centrally and in synchrony with each other, a central locking device is utilized,
This central locking device will be abbreviated hereinafter as "ZV device". The ZV device has drives, which act on the ZV levers in the individual locking devices and move them between two swing positions. In the usual case, the eccentric lever connected to the ZV lever then reaches the corresponding pivoting position, that is, the safety position in which the associated locking member is inactive, or the safety release in which the locking member is effectively set. To reach the position.

A locking device has a closing cylinder with a key-operable cylinder core, which is positively and / or force-coupled to the driver. This driver is arranged coaxially with the eccentric lever already described. In addition, an impact spring is provided which, after a key operation, automatically shifts the cylinder core to a neutral position, which is between a safe and a safe release position. In this neutral position, insertion and removal of the key into and from the cylinder center is possible.

[0003] Furthermore, however, the cylinder core can still be rotated by a key into a safe position beyond the safe position, in which the eccentric lever is locked. Furthermore, in the safe position, the key can likewise be inserted into the cylinder center and can be withdrawn.

In known devices, such as those described in the generic concept, the eccentric lever is fixedly connected to the ZV lever. Both levers are always able to swing in synchronization. This means that when the lever pair is in its safe position, but is activated by a control command coming from outside the device, and the ZV device attempts to move the ZV lever to its safe release position, the cylinder core is in the safe position in the cylinder center. Leads to operational failure. This leads to tightening inside the closing cylinder, which tightening eliminates or at least prevents the insertion of the key into the cylinder core. Such tightening
This occurs, for example, between the tumbler to be controlled by a key and the associated locking passage in the closing cylinder.

In a further known locking device, starting from a safe position, the lever pair is moved to its unlocked position, in which it is possible for the first time to operate the locking member of the device, so that a very large angle value is reached. Rotation of the cylinder center is required. That is, in known devices, the key must be turned from a safe position, beyond a neutral position, to a safety release position in the cylinder center. This large key rotation is not ergonomic and impairs operating comfort.

An object of the present invention is to provide the above-described operation flow, which is no longer generated, and which is superior in terms of a high degree of operational comfort, as described in the general concept of claim 1. It is to develop a reliable locking device. According to the invention, this is achieved by the measures recited in the characterizing part of claim 1 with the following special significance.

In the present invention, a connecting means is arranged between the ZV lever on the one hand and the eccentric lever on the other hand. This coupling means causes that when performing a key rotation in the normal angular range from the neutral position to the safety release position between the safety positions, both levers are locked together without rotation. However, when a safe position exists, in the present invention there is a decoupling of both levers. The above-mentioned operational disturbance in the safe position does not occur. This is because the ZV lever is not restrained and can be moved from the safe position to the safe release position without entraining the eccentric lever. As a result, no tightening takes place inside the closing cylinder. Further, a connecting member is arranged between the cylinder center and the eccentric lever, and when the key rotation is performed starting from the safe position and when the ZV lever is previously moved to the safety release position, The connecting member connects the cylinder center to the eccentric lever. In this case, a small key rotation is sufficient; the cylinder center need only be moved from the safe position to the neutral position in order to move the eccentric lever, which is in the safe position up to that point, to its unlocked position. This small angle of rotation is very easy to operate and makes the operation of the locking device easy.

[0008] Further measures and advantages of the invention are evident from the dependent claims, the following description and the drawings. BRIEF DESCRIPTION OF THE DRAWINGS The invention is illustrated in the drawings with reference to an exemplary embodiment.

The locking device shown in FIGS. 1 and 2 is at the rear of the vehicle to perform a closing function with respect to the rear flap. The locking device has a closing cylinder 10 which can best be seen from FIG.
, 12. The cylinder cores 11 and 12 are supported in a housing 13 arranged at a fixed position, and can be rotated by a key (not shown in detail). The cylinder core consists of an outer section 12, which is
It has a keyway 15 for accommodating a key which can be best seen from FIG. 1 with a protective cap 14. The end of the outer section 12 of the cylinder center protrudes outwardly from the vehicle body plate, which is indicated by a broken line in FIG. Here the key passage is accessible. Also located in this outer section 12 of the cylinder core are tumblers 16 which can be operated by keys, the positions of these tumblers being indicated by broken lines in FIG.

Another section 11 of the cylinder center is joined so as not to turn around this outer section 12. This section 11 is oriented towards the inside of the vehicle and is therefore referred to as the "inner section". The inner section 11 comprises various components 2 arranged coaxially.
0, 30, and 40. Between the two sections 11, 12 of the cylinder core there may also be an overload connection, not shown in detail. If the outer section 12 is subjected to a torque below a predetermined limit, there is a non-coupling between both core sections 11,12. Therefore, the key rotation of the outer section 12 causes the inner section 11 to rotate together in synchronization. However, if a torque exceeding this limit is applied to the outer section by an intrusion tool or the like, the overload connection disconnects the inner section 11 from the outer section 12 of the cylinder core. The outer section 12 entrained by the penetrating tool rotates idly in the housing 13, so that this rotation is not transmitted to the inner section 11 and the components 20, 30, 40 here.

An entrainer 20 first belongs to these components, and the entrainer is connected to the cylinder core 11.
It is rotatably supported above and has an axial projection 21 and a radial projection 22. Alongside the axial entrainment projection 21, there is also a stationary housing projection 75. These projections lie in an axial plane offset with respect to the sectional guidance in FIG. 3 and are surrounded by both legs 26, 27 of an impact spring 25, which is located around the cylinder core 11. The cylinder center is held in the neutral position indicated by the vertical line 50 by the impact spring 25. By means of the inserted key, the cylinder center can be pivoted selectively into a rotational position represented by the line 51 or 51 'in FIG. The associated rotation angles, represented by 53 or 53 'in FIG. 1, can be equal and each be at 55 °. When the cylinder cores 11, 12 are moved by the key to the rotational position 51 or 51 ′ and then released, the cylinder cores 11, 12 are automatically returned to the neutral position 50 again by the impact spring 25. To allow and limit this rotation 53, 53 ', the housing 1
3 comprises, according to FIG. 3, a window 29, which has end stops 28, 28 ′ for the driver projection 22.

The latter is evident from FIGS. 5a and 5b. In the section here, of the entrainer 20, only the axial entrainment finger 23 is shown, which is delimited by two radial shoulders 24, 24 '. In FIG. 5a, the rotation to the position 51 in FIG. 1 has been performed and in FIG. 5b the opposite rotation to the position 51 ′ of the cylinder center 11 has been performed, but in both FIGS. ,
Occupies the same position. At that time, the shoulder portion 24 in FIG.
4 'is a corresponding opposing shoulder 34 of the eccentric lever 30, another component of the device.
Or 34 ′.

The eccentric lever 30 is rotatably arranged on the cylinder core 11 by a support piece 33. The support piece 33 has the aforementioned opposing shoulders 34, 34 '. Due to the key rotation in the direction of the arrow 18, the eccentric lever 30 reaches the position evident from FIG. 5 a, this position being shown in solid lines in FIG. 1 and this position being represented by the auxiliary line 31. I have. Thereby, the first locking member 4 evident in FIGS.
Numeral 5 is moved to a position where another lock member (not shown in detail) to which it belongs is set invalid. Therefore, in this case, the eccentric lever 30 is in the “safe position”. The locking member 45 is in this case a sliding body which is movable on the guide bar 35 of FIG. 1, and this sliding body can also be moved on the bar 35 to an opposite position, not shown in detail. In this opposite position of the lock member 45, the lock member is effectively set.

By contrast, when the cylinder center 11 is turned by the key in the opposite direction as indicated by the arrow 18 ′, the shoulder 24 ′ and the opposing shoulder 34 ′ cooperate and the eccentric lever is moved in FIG. To another location 30 'apparent from This position 30 'is implied by the dashed line in FIG. Its position is indicated by the auxiliary line 31 'here. In this case, the first lock member 45 has been moved to a position not shown in FIG. 1, at which position the next lock member is effectively set. The lock can therefore be opened in this position 30 'by manipulation of the handle or the like. Thus, it can be seen that this position 30 'is the "safe release position" of the eccentric lever.

Another component of the device which has emerged is the so-called ZV lever 40 according to FIG. 6 a, which, on the other hand, is sandwiched by a support piece 43 on the previously described support piece 33 of the eccentric lever 30. , Are rotatably arranged on the cylinder core 11. The ZV lever 40 cooperates with the drive of the central locking device already mentioned earlier. This drive acts on the support hole 42 of the ZV lever 40 via a rod. The ZV lever 40 is shown in solid lines in FIG. 1 and by an auxiliary line 41 by this drive of the central locking device, or, as will be explained in more detail, by the aforementioned reverse rotation 18 'of the key. From the position shown in FIG. 6a, it is possible to move to another position 40 'shown in dashed lines in FIG. 1 which is recognized in FIG. 6b and represented by an auxiliary line 41'.

According to FIG. 2, the ZV lever 40 is fixed to the cylinder core 11 by the support piece 43.
, Wherein the ZV lever is axially fixed by a safety ring 19 or the like. According to FIGS. 2 and 6 a, both levers 30, 40 are normally non-rotatably connected by a connecting means 55. This connecting means 55
Consists, in this case, of a spring-loaded axially movable pin,
It is movable in the longitudinal direction within the radial guide 44 of the ZV lever 40. As can best be seen from FIG. 2, the pin 55 can be divided in the axial direction of the closing cylinder 11 into two pieces 56, 57, which have different lengths and In the following, the connection piece 56 and the control piece 57 can be referred to for obvious reasons. These pieces 56, 57 have a profile shape that is evident from FIG. 6a. The support pieces 43 and 33 of both levers 30, 40 have radial openings 36, 46, which are penetrated by pins 55. Pin 55 is spring loaded by spring 58 in the direction of arrow 59 in FIG. As a result, the inner end of the control piece 57 of the pin 55 is
7 is in elastic contact. For better guidance, the inner end of the control piece 57 has a rounded profile, while the inner end of the adjacent short connecting piece 56 is formed concave and the eccentric lever 30 It does not protrude inward beyond the support piece 33.

The radial passage 46 of the support piece 43 is limited to the profile width of the pin 55, while the radial passage 36 of the support piece 33 is formed to have a step in its width. , And have different inner widths for both pin pieces 56, 57. The radial passage 36 is narrowly defined in the range of the connecting piece 56,
Therefore, in the case that can be seen from FIGS. 6a and 6b, both levers 3
Between 0 and 40 there is a rotational entrainment. The two levers 30, 40 are then connected to one another in a non-rotating manner and, on the one hand, by the key rotation 18, 18 ′ or also by the drive of the central locking device, , 40 and 30 ', 40' on the other hand. Due to the effective and inactive positions achieved thereby of the locking member 45 already described with respect to the next locking member, both levers 30, 40 represented by lines 31 or 41
Is known as the "safe position", whereas the other positions 30 ', 40' of both levers, represented by the lines 31 'or 41', are the "safe release positions" already mentioned.

The stepped radial passage 36 in the support piece 33 of the eccentric lever 30 is
In the region of the long control piece 57 of the pin 55, it has a large width, which is evident from FIG. 6a already described, which is delimited by the rotary stops 38, 38 '. These rotary stops 38, 38 'correspond to the angle difference 47 between the two positions 40, 40' represented by the auxiliary lines 41, 41 ', which is evident from FIG.
The swing of the ZV lever 40 relative to zero is enabled. This is used in that special case, as is evident from FIG. 6d, in which the cylinder core 11 is in a so-called "safe position", which is indicated in FIG.
Is represented by

This safe position 52 in FIG. 1 is achieved, starting from the neutral position 50, only by a key rotation of the cylinder core 11 by an angle value 54, which is much larger than the aforementioned rotation angle 53. . This angle value 54 is 90 ° in this case. This angle value 54 is also entered in the cross-section representation in FIG. 4b, which shows the safe position 52 of the cylinder core 11 shown here with a dot. The neutral position 50 of the cylinder core 11 in the same cross-sectional view can be seen in the preceding FIG. 4a and is marked in FIG. 4b by an auxiliary line 50. In the passage 48 on the diameter of the cylinder core 11 there is a spring and two balls 49. These spheres
4a and 4b, are pushed radially outward into notches 29 or 29 'by the spring force indicated by the arrows, which are in the ring opening of the driver 20. Therefore, in the normal case according to FIG. 4a and in the special case according to FIG. 4b, there is first a force-coupled connection between the driver 20 and the cylinder core 11. However, on the one hand the ring opening of the driver and on the other hand the cylinder core 1
The circumference of one has a non-round contour. 4a, or in the special case according to FIG. 4b, a further rotation stop 39 'acts between the driver 20 and the cylinder core 11.

In the normal case of FIG. 4 a, as already explained with reference to FIGS. 5 a and 5 b, the driver 20 is moved from the neutral position represented by the auxiliary line 50 to the aforementioned arrows 18, 18 ′
, The protected and unprotected rotational position 51 of FIG.
Moved to 51 '. As seen in FIG. 4a, at this time both components 20, 11 move together. This takes place first because of the aforementioned force connection between the two balls 49 and the recesses 29. But still further, as is evident from FIG. 4a, there is a positive connection between these components 20,11. This shape connection, in this case,
It is constituted by a sphere 32 or the like which is freely movably arranged in the radial opening 62 of the entrainer 20. This is because the sphere 32 is engaged by a part of its cross-section in the radial recess 63 of the cylinder core 11. 4a, the entrainer 20 is also entrained by a positive connection during the aforementioned rotation 18, 18 'of the cylinder core 11 according to FIG. 4a. Thus, in the normal case of FIG. 4a, both components 20, 11 move synchronously during rotation.

This changes when the cylinder core 11 is moved to its safe position 52 here, when it transitions from the normal case to the special case of FIG. 4b. Housing 1
On the inner surface of 3 there is a radial opposing recess 64 in which the sphere 32 arrives after an initial rotation 65 of the units 11, 20, which are movable together according to FIG. Is this initial rotation 65 greater than the rotation angle 53 described in connection with FIG.
It can be equal to this. After this initial rotation 65, the ball 32 is
And can be removed from the radial recess 63 of the cylinder core 11.
The sphere 32 is pushed into the opposing recess 64 in the radial opening 62 by the contoured surface of the cylinder core 11 represented by 66 in FIG. At this time, there is a positive connection between the housing 13 and the driver 20. This particular position of the entrainer 20 can be recognized by its entraining finger 23 ", represented by 23" in FIGS. 5c and 5d. The entrainment body 20 is stopped by this shape connection. During the remaining rotation 67 of the cylinder core 11 implied in FIG. 4a to the complete angle value 54 evident from FIG. 4b, both balls 49 are first lifted out of their conventional notches 29,
The conventional rotary stopper 39 of FIG. 4a comes off. The ball then falls into the already described rotationally offset notch 29 'inside the ring of the entrainer 20, so that a second locking position is evident from FIG. 4a. At this time, however, there is a rotary stop 39 between the two components 11, 20 due to the non-round profile already described. As a result, the rotation angle value 54 of the cylinder center 11 is limited.

In the safe position of FIG. 4b, the situation is evident from FIGS. 5c to 6d.
The key passage 15 occupies a position perpendicular to the neutral position 50 in front of FIGS. 5a to 6b in the safe position. In this safe position, pulling out and insertion of the key from the cylinder core 11 are possible without any restriction. This is achieved by another locking passage, not shown in detail, inside the housing 13, in which the end of the previously described tumbler 16 evident in FIG. 2 can enter. Due to the mechanism already described, the eccentric lever 3 in the safe position
0 is in its safe position, which is basically represented by the auxiliary line 31, where the associated lock is set to invalid. According to FIGS. 5 c and 5 d, the eccentric lever 30 is furthermore locked in its safe position 31. The entraining finger in position 23 "bears by means of its shoulder 24 the corresponding opposing shoulder 34 of the eccentric lever 30. Therefore, it is not possible to rotate the eccentric lever 30 in the direction of arrow 68 in FIG. .

In the safe position 52 of the cylinder core 11, the connection of the ZV lever to the eccentric lever 30 is released, as is apparent from FIG. This means that the cylinder core 11
The control surface 37 pushes the end of the long control piece 57 of the pin 55 radially outwards against a spring force 59. As a result, the adjacent connecting piece 56 of the common pin 55 comes out of its associated narrow area in the radial opening 36 of the eccentric lever 30 and its concave end releases the associated support piece 33. . The disengaged ZV lever can thereby be moved from the secure position shown in FIG. 6c to its unlocked position, which is clear from FIG. 6d, by means of the already described drive of the central locking device. However, the eccentric lever 30 locked in the safe position 52 does not change its position. Thus, also in the unlocked position 40 'of the ZV lever according to FIG. 6d, the lock member cannot be operated; the lock is in the inactive position.
In the case of FIG. 6d as well, the pin 55 is in the uncoupling position already described. The end of the control piece 57 is resiliently supported by a convex continuation 69 represented by 69 of the control surface 37 of the cylinder core 11, which in this case
This is because the peripheral surface of the cylinder core 11 is simply formed.

However, between the cylinder core 11 and the eccentric lever 30 there is still a special connecting member 60, which in this case consists of a roller. The roller 60 corresponds to the concave area 71 of the control profile in the cylinder center 11 and the concave area 72 of the opposite profile on the inner surface of the support piece 43 of the ZV lever. 6d, the support piece 33 has a radial hole 70 for the roller 60 to be loosely received therein.

Due to the locked position of the eccentric lever 30 in the safe position 52 and the rotational entrainment in the radial hole 70 in FIGS. 6c and 6d, the roller 60 is also in the rotational position indicated by 61. In the safe position of FIG. 6c, the ZV lever is still aligned with the roller 60 by its concave area 72 of the opposing profile, but this changes in the safe release position of FIG. 6d. Because, at this time, the convex area 73 of the opposing profile in the support piece 43 corresponds to the concave area 71 of the cylinder center 11.
It is because it pushes. This convex area 73 is simply formed by the inner ring surface of the lever support piece 43.

At this time, starting from FIG. 6D, the cylinder core 11 is moved from the safe position 52 again to FIG.
When trying to move to the neutral position 50 in the direction of the return rotation arrow 18 "of d, the ZV lever remains in its safe release position. The end of the concave area 71 of the control profile is
When hitting the roller 60 which has been stopped by this time, the entrainer 20 is also released after the initial return rotation indicated by the rotational arrow 74 from FIG. 4b; the ball 32 is again placed in the radial recess 63 of the cylinder core 11. Fall into There is then again a locking engagement between the two balls 49 and the other notch pair 29 of the driver 20. Then again the driver 20 automatically rotates back to the neutral position 50, as during each normal closing movement. At this time, the eccentric lever 30 is swung by the cylinder core 11 and the roller 60 to the safety release position 30 '. The eccentric lever 30 is thus simultaneously swiveled by a complete angle value 47 which is evident from FIG. 1 during a return rotation 18 ″ with an angle value 54 between the two positions 50, 52 of 90 °. Thus, the key does not need to be turned any further, corresponding to an angle value 54 between 50 and 52. This provides a comfortable operation simplification.

At this time, according to FIG. 6 b, both levers 30 ′, 40 ′ are again in their respective unlocked positions. The roller 60 has reached the rotational position 61 'in FIG. 6b, where it is again aligned with the concave area 72 of the opposite profile belonging to the ZV lever. Then again the pin 55 has reached its connecting position, in which both levers 30 ', 40' are connected to one another so that they do not rotate again. These levers can be re-synchronized to their safe position, which is evident from FIG. 6a, via the drive of the central locking device, which selectively engages at 42 of the ZV lever 40 'in FIG. 6b. With respect to the connecting member 60, the following control movement then takes place.

During the key rotation represented by 18 in FIGS. 5 b and 6 b, first, as already mentioned, via the shoulder 24 of the entraining finger 23 and the opposing shoulder 34 of the support piece 33
The eccentric lever 30 'is also entrained, so that the radial hole 7 in its support piece 33
In the case of 0, the roller 60 is also entrained. The roller 60 therefore rides on the peripheral surface 69 of the cylinder core 11, which at this time serves as the convex area of the control profile, which, according to FIG.
Into the concave area 72 of the opposite profile. Then both levers 30,
There is a second form-locking connection between 40; besides the pin 55 which is effective for the connection, the roller 60 also brings together both levers 30,40.
