Abstract

The aim of the invention is to improve locking devices, especially for use in motor vehicles, in which a locking cylinder is mounted on at least one door and this locking cylinder is operated by a key (10) which has code tracks (13) on the flat sides (11) thereof. To this end, the profile (14) which typifies the key (10) and which, according to the state of the art, is arranged in the outer areas of the flat sides (11) of the key (10) is realized in the form of a groove (14) that is located on the narrow sides (12) of the key (10) and recessed therein. In addition, a projection is provided on the upper and/or lower narrow side of the key channel of the locking cylinder and, when the key (10) is inserted, the projection engages inside the groove (14') located on the key. The inventive measures permit the height of the key (10) to be reduced since the edges of the flat sides (11) of the key (10) can be brought close to the code path (13). In addition, the key (10) wobbles less by virtue of the fact that the projection is guided in the groove (14') when the key is inserted into the locking cylinder.

Description

Be used in particular for the locking device of motor vehicle

The present invention relates to a kind of type of skill locking device as described in the preamble that belongs to claim 1.Application of the present invention is motor vehicle etc. particularly.

Under the locking device situation of the above-mentioned type, be well known that and sent out at a quilt.Hu Fu (Fa.Huf) makes on the key, to have disposed encoded tracks symmetrically on two flat sides of key with the longitudinal axis rotation of key.On each of this two flat sides, in the zone at an edge, be provided with one respectively and make the standardized abnormal shape of key.These abnormal shapes that are positioned on two flat sides of key are to place symmetrically mutually to settle equally.By the rotational symmetric structure configuration of encoded tracks and abnormal shape, key just can be directed on two possible insertion positions in the key channel of a lock system.

This lock preferably is positioned on the door of a motor vehicle or the cover cap and by the operation that is inserted into the key in the key channel being realized to the locking of an operating means that is used to open a latch fitting or release or the realization operation to a derailing switch.

In order not to be that any key all can be imported in each lock, then describe as top, on the exterior zone of described flat side, be provided with abnormally-structured.Wherein, this abnormal shape of key for dissimilar locks by configuration differently with definite size; And respectively with the sidewall of key channel on correspondingly configured suitable every rib/raised structures.

This encoded tracks requires a definite minimum constructive height for the reason of manufacturing technology, does not have to rub in encoded tracks and can not pass through with hooking so that it also guarantees to make bolt when key is directed in the key channel.

Above the defective of this locking device be, the opening resistance of this lock can not further be lowered by dwindling of key channel because under it minimum constructive height of key by the technical decision of encoded tracks height and described abnormal shape by gauge.

In the known key key height reduce also can cause, these abnormal shapes that settle outside on the flat side of key will be cut described encoded tracks and can be opened these encoded tracks.Then, this key will no longer work.

Therefore task of the present invention is, a locking device of alleged type in the preamble section before the claim 1 is done development improve, to eliminate described defective.This task require to be that according to invention in the characteristic by claim 1 alleged measure realizes, it has following special meaning.

The abnormally-structured form with a groove that will be used to distinguish different key type according to claim 1 need is arranged at least one narrow side.By this measure, this key height can further be reduced, because this encoded tracks can not be again by this abnormally-structured being cut open.By described contingent the reducing of key channel, this lock system also becomes can be antitheft, because this opener must be littler for any situation, just can be directed in the key channel, and the maximum power that can apply also diminished.

In addition, just obtain wonderful effect in the time of on one or two the narrow side that a groove is arranged on key, key promptly of the present invention has reduced the described effect of waving and has therefore repeatedly imported and operating the especially little wearing and tearing that realized this lock and system bolt under this lock situation with key.

Be that a groove that is closed towards three vertical sides is closed on its and two flat side surface direction with respect to key inner with respect to key according to what claim 2 related to regard to being used for the standardized groove of key.

If as what stipulate in the claim 3, these grooves are separately positioned on two opposite opposed narrow surfaces of key, this key also can be imported in the key channel on each possible insertion position so.Yet this also relates to one and turns to key.

In addition, according to claim 4 highly significant be, a raised structures/every rib is set on the corresponding position in key channel, it just is engaged in this groove/these grooves of key when key inserts in the key channel.

According to claim 5 also highly significant be, on its side end, have a stop surface and this stop surface will be run into a head surface of settling on raised structures at the groove of settling on the key, the insertion of key has been limited according to this.

Surface relief structure more than the groove that is provided with according to claim 7, it can be changed for each key type, this is the number on surface in particular, and their mutual angles also have this surperficial form to change, and can make the key type of an enormous quantity according to this.

Surface segment and smooth surface segment in flute surfaces the combined setting and once more increased of this diversification in styles by will be radially.

According to claim 9 highly significant be, this will import to raised structures in the groove/have the side surface that is fit to like this every rib, the part of its surface segment corresponding with the key side at least in this groove is the shape connection.

By the different releasing structure of this groove and in key channel the releasing structure of the correspondence of raised structures just can in a lock system, on a master key, dispose the secondary key of a plurality of patterns accordingly.

The present invention's other measure and advantage can be by obtaining in dependent claims, following manual and the accompanying drawing.Embodiments of the invention have been described in the accompanying drawings.It shows:

Fig. 1 is the three-dimensional sketch of a key of the present invention;

Fig. 2 is along the sectional view that cuts open timberline II-II among Fig. 1;

Fig. 3 is corresponding to Fig. 2, the sectional view of another embodiment by key of the present invention;

Fig. 4 is corresponding to sectional view Fig. 2, that pass through one of prior art inner orbit key, and its height is corresponding to the height of the key in Fig. 2 and 3;

Fig. 5 is the lock sketch of the present invention in car door.

Locking device of the present invention is especially at the lock that is used for inner orbit key or hole slot key.

Locking device of the present invention comprises a lock 20, and its rotating post core (not shown herein) in a post shell (not shown herein) is lockable under normal mode by a plurality of spring-loaded system bolts 27.Be lamella made bolt under the situation shown in current.These system bolts 27 are importing up to specification just so being regulated under key 10 situations that are equipped with encoded tracks 13 on its planar side 11, that is, this system bolt no longer stretches out by the perimeter surface of post core, so this post core is just rotatable in the post shell.By the key 10 that rotates this insertion, the user just can be on this basis by this locking device and according to rotation direction release or operating means of locking of key 10.

This key 10 is being pushed in a lock 20 key channel 21 as shown in Figure 5 under the situation, the system bolt 27 that should settle in key channel 21 will cross the encoded tracks 13 that this is settled in this embodiment on two flat sides 11 of key 10.This makes bolt 27, and the abnormal shape figure that settles along encoded tracks 13 just pushing under key 10 situations according to guidance surface 16 moves in the lock 20.Just be at this system bolt on the terminal location of key 10 on the position of its post core that allows lock rotation.

Under key of the present invention 10 situations of describing as Fig. 1-3, a groove 14 ', 14 " is positioned on two narrow sides 12 of key 10." have one and discharge abnormal shape 17, it of comprising different surfaces segmentation 18,19 connects arrangement architecture to this groove 14 ', 14.Just can make many different groove types by the connection arrangement architecture of this different surfaces segmentation 18,19, make it is not that any key 10 can import in each lock 20 of this form of structure of predesignating into.

In the present embodiment of the master key of as shown in Figure 2 a lock system, except the surface segment 19 on plane, also settled post-surface segment 18, they have constituted the release abnormal shape 17 of groove 14 '.In the secondary key of in Fig. 3 sectional view, describing 10 ', belong to same lock system, be also included within the master key of describing among Fig. 2 10, only at groove 14 " the release abnormal shape in settled the surface segment 19 on plane.Secondary key 10 ' according to Fig. 3 can not be inserted in the main lock, because of its only with Fig. 2 in the master key 10 corresponding configurations described.But in contrast, this master key 10 also can be inserted in the lock with secondary key a 10 ' corresponding configuration and operate it.

As opposed members with respect to the groove of key side, on the narrow side 22 of the key channel 21 of lock 20, be provided with raised structures 24 (referring to Fig. 5), it settles with the longitudinal extension of key channel 22 with paralleling.
