Definitions
- the invention is directed to a closure device in the preamble of claim 1 specified type.
- the axial clutch and the overload protection ensures that the actuation of the closing functions only about the proper, in the cylinder core of the Lock cylinder inserted key are executable, but not by Tampering with a burglary tool.
- the overload protection of the locking device ensures that the locking cylinder is overloaded in the Casing.
- the latching and counter-latching part of this overload protection system rise automatically axially and also release the axial coupling between the cylinder core and the driver. This can cause violent rotation of the locking cylinder does not affect the rotation of the driver.
- the overload protection prevents the closure device is damaged in the event of violent attempts to break open. Therefore the device later with a proper key to Enforcement of the locking functions in the motor vehicle can be used.
- overload protection can provide axial forces when used from intrusion tools and stay engaged when turning violently the tumblers can be sheared off. Thereby can ultimately undesirable via the intrusion tool the locking functions are exercised.
- the lock cylinder destroyed by shearing the tumblers and not the device again operated via a key. This danger of departure can be avoided lower with a lifting profile with particularly flat flanks, but functional problems then arise.
- the invention has for its object an inexpensive, compact closure device the type mentioned in the preamble of claim 1 to develop in which the locking cylinder is no longer in the event of an overload moved axially.
- This is according to the invention by the in the characteristic of Claim 1 measures achieved, the following special Importance.

- the associated locking part of this overload protection is is not an integral part of the housing, but a separate one Part that can be moved axially in the housing.
- the housing has an axial guide, in which this locking part is axially displaceable but non-rotatable is positioned. The axial guide now acts on this separate one Locking part axially and loads it in the direction of the already mentioned axially fixed counter-locking part of the cylinder guide in the housing.
- the cylinder core also remains axially fixed in the event of an overload in the housing because it is axially fixed in its cylinder guide.
- the coupling member connected to the cylinder core the axial coupling axially fixed, while that connected to the driver Counter coupling member axially displaceable together with the locking part are. So if the locking part in case of overload against the axial spring load is pushed back, the counter-coupling member is released automatically from the coupling member axially fixed to the cylinder core Axial coupling.
- the lock cylinder also leads in the event of an overload no axial movements. The front end of the cylinder core can always be flush with the housing.

- the ball 41 will at a defined torque via the inclination of the inclined flank 44 lifted out of the axial recess 43 of the cylinder core 20 and drives onto the inner end face 28 of the cylinder guide 20.
- the pressure ring 33 is in the sense of already mentioned arrow 34 axially against the axial spring force 50 of the spring pushed back.
- the axial nose 35 located on the pressure ring 33 moves into the axial gap 26 between the two fingers 25 of the driver 23 a. Because of this longitudinal displacement 34 of the pressure ring 33 it comes also to release the axial coupling 30, as can be seen from FIG. 2.
- the coupling member 31 located on the cylinder core 10 remains axial stand, but the pressure ring-side counter-coupling member 32 moves away from it in the sense of the already mentioned longitudinal displacement arrow 34.
- the cylinder core 10 is together with the cylinder guide 20 in the sense of the rotary arrow shown in FIG. 2 29 rotated in the housing 16, but without this rotation 29 itself can affect in a corresponding actuation of the driver 23.
- the axial clutch 30 is namely released.
- the locking cylinder 10, 20 is located itself in an overload freewheel.
- the spring 51 described determines together with the inclination of the inclined surfaces 44, the limit value in the locking mechanism 40, in which the overload freewheel of the locking cylinder 10, 20 occurs. This limit is dimensioned so that there is definitely no damage the tumblers 14 of the cylinder core engaging in the blocking channels 24 10 occurs.
- the lock cylinder remains ineffective after the end Burglary attempts, again operated via key 15. Noteworthy is that the whole lock cylinder 10, 20 its through the aforementioned dash-dot line 39 in Fig. 1 and 2 illustrated axial position in the housing 16 not changed.
- the pressure ring 33 is only coupled to the cylinder core 10 1 in the housing 10 rotatable, but already at one small shift in the direction of the decoupling position shown in Fig. 2 guided non-rotatably in the housing 16. This is best done from Fig. 8 and 9 visible axial projection 38 on the pressure ring 33 and two best seen in Fig. 3 radial ribs 48 on the inner surface of the Housing 16.
- the projection 38 is in the normal case, according to FIG. 1, in the axial Distance to the end of the ribs. However, the one shown in FIG. 2 takes place Longitudinal displacement 34 of the pressure ring 33, the projection 38 moves in 3 shows the axial gap 49 between the two radial ribs 48 as best seen in the sectional view of FIG. 7 is.
- a modified embodiment is the second exemplary embodiment of FIG. 10 the locking mechanism 40 'shown.
- the counter-locking part 42 of the overload protection on the cylinder guide 20 is the same Formed as a recess 43 with inclined surfaces 44. It is sufficient, only go into the differences of this locking mechanism 40 '.
- the associated latching part 41 ' is part of what is shown in FIG. 10 special ring body 46, which is axially displaceable in the housing is.
- the ring body 46 has two radial lugs 47, which into the two axial grooves 45 already mentioned on the inner surface of the housing 16 intervene.
- the locking part 41 ' is profiled and has it Fall an outline, which is complementary to the described lifting profile of the counter-locking part 42 is designed.
- the annular body 46 is the axial bolt 11 enforces that explained in connection with FIG. 2 violent rotation 29 freely rotate relative to the ring body 46 leaves.
- the pressure ring 33 described in the previous embodiment arranged be, but then no longer the balls described above 41 has.
- the described axial clutch 30 is then in a similar manner as in the previous embodiment, namely between the axial bolt 11 and the pressure ring 33.
- the embodiment according to FIG. 10 could also be used for the next device, which will now be described.
- 11 to 14 is a third embodiment of the invention Locking device shown.
- the corresponding names Components the same reference numerals as in the previous Embodiment used, which is why the previous one Description applies.
- These figures correspond to the figures in FIG. 1, 2 and 4 and 5 of the first embodiment. It is enough just to address the differences.
- the axial spring load 50 acts here on the driver 56 on the in this case also formed as balls 41 locking part of a locking mechanism 40, which is already in connection with the first embodiment Analog overload protection described when using violence 12 causes.
- the inner end is supported the spring 51 via the snap ring 22 on the axial bolt 11, while the outer spring end acts on the driver 58.
- the driver 58 axially offset and has, similar to the pressure ring 33 in the first Embodiment, a radially offset peripheral zone shown in FIG. 14 56 and an adjacent radial heel surface 47, the Balls 41 of the locking mechanism sit again in axial grooves 45 from the housing, run on the peripheral zone 56 and are supported on the sales surface 57 from.
- the axial coupling 30 ' is similar in shape and effect as in the first embodiment, but there is a difference in that the dashed coupling in Fig. 12 and 13 highlighted 32 'is an integral part of the driver 58.
- the driver too 58 has an axial projection 59 which, in the normal case, according to FIG. 11, at an axial distance from the radial ribs provided in the interior of the housing 48 is arranged. In the event of an overload, as shown in FIG. 12, the projection moves 59 of the driver 58 in the free gap between the two radial ribs 48 and ensures that the driver 58 cannot be rotated in the housing 16.
- the arm 60 protruding from the driver 58, which is used for the execution of the locking functions is therefore in the transition to an overload case of Fig. 12 rotatably fixed relative to the housing 20.
- FIG. 11 to 14 Another difference of this third exemplary embodiment from FIG. 11 to 14 is that the longitudinal displacement 34 in the event of an overload of Fig. 12 in a corresponding displacement 34 of the entire driver 58 affects.
- This axial displacement 34 of the arm 60 has for Closing function is of no importance, because in the case of overload of FIG Non-rotatability of the driver 58 secured via the components 48, 59 is. You could this axial displacement 34 of the driver arm 60th also use it to free the arm 60 additionally with the subsequent lock link.
- This longitudinal shift 34 of the driver 58 does not affect the front in any way Range of the device from FIGS. 11 to 14. As can be seen, remain there the cylinder guide 20 and the cylinder core 10 located therein in unchanged, axially fixed position, as also there by the corresponding Dash-dot lines 39 are illustrated in FIGS. 11 and 12.
