Abstract

A closing device (10) with a rotor (11) which has a cylindrical periphery (17) and which accommodates spring-loaded locking mechanisms on one side. With a closing device of this type, a pivoting tilting moment of the locking mechanisms may occur. A stator (21) for rotationally mounting the rotor (11) has a blocking channel (22) which is delimited by two flanks (23, 24) and into which the end of the spring-loaded locking mechanisms moves when the key is withdrawn, hereby preventing the rotor (11) from turning. Starting from a zero position, the rotor (11) can be moved into at least one other working position in two opposite directions (25, 26), respectively. The aim of the invention is to render the device more secure against break-in attempts by picking. To this end, there is a widened channel section (40) in the stator (21) on the flank (23) of the blocking channel (22) that is oriented in the direction of the tilting movement (25). Said widened channel section (40) has a larger inside width (41) than the rotor receiving element but is flatter than the radial depth (42) of the blocking channel (22). When the rotor (11) is moved into a rotation position in the direction of the tilting direction of the locking mechanism following manipulation, the locking mechanism rests on an inwardly pointing support surface provided inside the widened channel section (40) with its end. The locking mechanism therefore projects beyond the periphery of the rotor (11), hereby intercepting any rotation of the rotor (11) back (26) in the opposite direction of rotation from the other flank (24) of the blocking channel (22), resulting from further manipulation.

Description

Rotor in the stator has the locking device that is particularly useful for automobile that spring carries lockable mechanism

The present invention relates to the locking device of the described type of a kind of preamble as claimed in claim 1.This device suffers the person's of having no right the trial of prying open.A kind of method of prying open is a kind of omnipotent unblanking (Nachschliessen) by so-called " theft method ".In this case, the lockable mechanism in the rotor is without permission, does not promptly have selection (einsortieren) corresponding regulation key of attaching troops to a unit, and rotor can be rotated in stator by a tool for destroying.This is by successively lifting single lockable mechanism continuously, simultaneously rotor is applied that torque carries out.Because between lockable mechanism and its guide rail in rotor and and stator in inevitable error between the keyhole size, the lockable mechanism of being handled can be bearing on the inner face of accommodation hole in the stator by seamed edge outside it after removing torque.Therefore this lockable mechanism at first is fixed on the position of its selection.Corresponding process is to implement with second lockable mechanism subsequently.This finally also can carry out at every other lockable mechanism continuously.This method is by following situation support.

Each lockable mechanism is to be one-sided spring-loaded in rotor.Can produce the upset of lockable mechanism in rotor because of above-mentioned error thus; A torque is arranged on lockable mechanism, make this lockable mechanism crooked to rotation direction.This rotation direction of rotor abbreviates " reverses direction " below as.Easier aforementioned omnipotent the unblanking of carrying out by the theft method of opposite direction, this opposite direction is hereinafter referred to as " reverse flip direction " at the reverses direction ratio.This device can rotate to both direction from the zero position of an expression resting position usually, and this both direction plays difference in functionality in corresponding lock or equipment.A rotation direction, i.e. reverses direction can make the lock locking that this device attaches troops to a unit or other equipment of attaching troops to a unit work, in the then release or inoperative of reverse flip direction.People without permission may expect further improving the theft method, makes lockable mechanism be handled the position that the relative rotor in back at least temporarily is fixed on its selection at its upturned position.This fixing can being undertaken by a kind of cold spray (K  ltespray), this method make in radial motion short time of lockable mechanism owing to spring-loaded and inoperative; Rotor and lockable mechanism have constituted a temporary transient rigid structure unit.This element of construction turns round to the reverse flip direction by tool for destroying then.This moment, temporarily fixing lockable mechanism arrived opposite side by keyhole, made thus to arrive an operating position, and this position has only usually with the key of regulation and could realize, for example made the affiliated lock release of device or made corresponding apparatus inoperative.Therefore by this theft method that changes slightly, can make fairly simple theft method not only can be used to realize important lock function, and can pry open lock along the reverse flip direction by cold spray or similar approach along reverses direction.Because this improved method of prying open just produced very big danger, promptly the lock function that needs protection especially that kept of rotor reverse flip direction has been subjected to threat.

Task of the present invention provides and a kind ofly provides the locking device of the simple compactness of type as claim 1 preamble, and it can't be pried open or be difficult to pries open.According to the present invention, this task realizes that by the described measure of claim 1 characteristic it has following Special Significance.

Measure of the present invention is, aforementioned lockable mechanism is not the position of selection completely that is positioned on the rotor circumference after the reverse theft method of rotor upset having implemented, and this position is for being essential by tool for destroying or similar item rotary rotor or reverse flip rotor.Be responsible for by the described passage of claim 1 characteristic expansion section for this reason.Behind the upset reversible control, although rotor also is positioned at a turned position, lockable mechanism still extends radially out the circumference above rotor.Lockable mechanism is engaged in the passage expansion section, abuts on the bearing surface in the sensing at this place's lockable mechanism.If adopt above-mentioned destruction methods this moment, in the turned position that rotor is handled,, be useless then for the rotation along the reverse flip direction conversely by cold spray or similar approach pin locking mechanism.That is, in this reverse rotation, the lockable mechanism that stretches out above circumference has bumped against on the side, opposite of keyhole.Thereby rotor is stuck in the stator.Stoped thus and pried open device of the present invention.

Other advantages and measure are provided by dependent claims, following description and accompanying drawing.The present invention shown in the drawings and prior art embodiments.Show the device cross section that is in diverse location respectively with enlarged drawing among the figure.

Fig. 1 is a kind of locking device of prior art, and wherein key is pulled out the zero position that the back rotor is in the expression resting position,

Fig. 2 has inserted key in the lock shown in Figure 1,

Fig. 3 is a lock shown in Figure 1, wherein successfully implements aforesaid theft method by a unshowned tool for destroying in the reverses direction of diagram lockable mechanism upper edge rotor,

Fig. 4 is similar to Fig. 1, is the initial state of device according to the present invention before inserting corresponding key,

Fig. 5 is similar to Fig. 3, is the initial period of lock of the present invention shown in Figure 4 being implemented the theft method,

Fig. 6 is right after the latter half after shown in Figure 5 when apparatus of the present invention shown in Figure 4 are implemented the theft method,

Fig. 7 stops the final stage of prying open lock when apparatus of the present invention shown in Figure 4 are implemented the theft method.

Fig. 1 to 3 shows the locking device 10 ' of prior art, and shows locking device 10 of the present invention at Fig. 4 to 7.In order to indicate corresponding member, used identical Reference numeral in both cases.Shown in Fig. 1 to 7, described device 10 or the following same structure of 10 ' main existence.

Device 10 or 10 ' comprises a rotor 11, and this rotor has a guide 12 radially to be used for the lockable mechanism 13 of a sheet.This lockable mechanism 13 is in unidirectional by the spring-loaded shown in the power arrow 14.Be arranged in a spring 15 in the side direction chamber and be used for spring-loaded, this spring 15 is pressed to lockable mechanism one end 16 among of keyhole 22 of dual setting herein when key is extracted.Keyhole 22 radially is arranged in the stator 21.In this case, device 10 or 10 ' comprises gang's lockable mechanism, when the key that inserts as can be seen from Figure 2, in the position that vertically is misplaced mutually of the engaging-in control curve 31 of these lockable mechanisms, described control curve is here formed by a conduit wall of special-shaped passage, but also can with other modes for example breach track form constitute.Because key 30 here is so-called " revolution key ", this control track 31 is arranged in the mirror-image arrangement mode in the both sides of key axle.For the space reason, the adjacent lockable mechanism in this family's lockable mechanism alternately is subjected to the effect of its spring-loaded 14, and therefore adjacent lockable mechanism 13 enters in one of two opposed keyholes 22 under no key state shown in Figure 1.This keyhole 22 is limited by two sides 23,24.Rotor 11 has a cylindrical side face 17, and it stretches out from the end 16 of lockable mechanism 13 in original position shown in Figure 1.

Stator 21 has a cavity 27 that mates with outline 17, and as shown in Figure 2, rotor 11 can be to 25,26 rotations of two opposite directions by inserting key 30.Rotor 10 original position under static state abbreviates " zero position " as below by 11.0 expressions of the chain-dotted line among the figure.Rotor 11 longitudinally has a suitably key channel 18 of abnormity, there is shown its axis 20, so that can rotate to two directions of

arrow

25 or 26 by rotor 11.Usually use key 30 for this reason.At the insertion state of key shown in Figure 2 30, lockable mechanism 13 order is distributed on the side face 17 of rotor 11 and no longer reaches in its keyhole of attaching troops to a unit 22.This order distributes and realizes by the subtend convex shoulder 19 of locating corresponding to the affiliated tracking point of the control curve 31 in key 30.In order to realize personalization, at one for example in the sheet system of eight lockable mechanisms 13, on a short transverse and/or another short transverse, there are four height steps different just to be enough to distinguish the difference of single assembly 10 or 10 ' with the starting altitude of control curve 31.

Then by inserting key 30, it is same by first operating position shown in the chain-dotted line plane 11.1 that rotor 30 and lockable mechanism 13 are forwarded to herein from aforementioned zero position 11.0 when rotation 25 shown in Figure 2, driving lever that links to each other with rotor 11 in this operating position or similar item can implement should with the function of wanting of 10 or 10 ' the coefficient equipment of device.11.1 be in a plurality of operating positions of rotor 11.In this case, in order to distinguish notion, with the reason that describes in detail, will be called " reverses direction " along the rotation of arrow 25, and rightabout rotation 26 is called " reverse flip direction " because of below.Because the inevitable scale error of the guide 13 in lockable mechanism 13 and the rotor 11 loads 14 by unidirectional spring and can make lockable mechanism 12 crooked, as shown in Figure 1.Produce a torque that acts on the lockable mechanism 13 thus, its direction is illustrated by arrow 28 in Fig. 1.This upset 28 is by the inner check restriction, for example by the protuberance backstop of holding spring-loaded 14 on the cavity 27 of stator 21.Concerning the following method of prying open of so-called " theft method ", the seamed edge 32 of reverses direction 25 arrives a more favourable position than another seamed edge 33 in sensing Fig. 2 of lockable mechanism shown in Figure 1.Further set forth by Fig. 3 below.

In the theft method, as described in starting, overcome spring by a proper tools and carry the lockable mechanism that 14 priorities promote each obstruction, its rotor 11 is arranged in Fig. 1 zero position 11.0 places.Simultaneously, a slight torque puts on the reverses direction 25.The result is come out from keyhole 22 by the lockable mechanism 13 handled finally as shown in Figure 3, just still is supported on its favourable seamed edge 32 on the inner surface of the cavity 17 in the stator 21.In lockable mechanism subsequently, implement this method in a similar manner.At last all lockable mechanisms 13 of rotor 11 are implemented, thereby lockable mechanism seamed edge 32 is supported on the inner surface of cavity 17 of stator, make rotor 11 can do the rotation of a minimum from zero position shown in Figure 3 11.0.After this first failure stage, rotor 11 can forward the operating position 11.1 here to along reverses direction 25 shown in Figure 2, also can realize by tool for destroying at the corresponding function of this location means 10 ' or 10.

In device 10 of the present invention, shown in Fig. 6 and also the operating position 11.1 that further describes is had one to installing 10 the less important function of safety, for example when being used for automotive lock, pin corresponding lock.Although arrived operating position 11.1 by aforesaid operations thus, but still can not realize opening lock 10 of the present invention.Although in known devices 10 ', can have a similarly configuration, therefore aforesaidly adjust rotors 13 by tool for destroying to reverses direction 25 and can not realize prying open lock, finally can pry open known this device with other following knack.

As shown in Figure 3, in known devices 10 ', can temporarily fix by the abundant propelling position of lockable mechanism 13 in stator that the operation to reverses direction 25 realizes.For example to introduce a kind of cold spray 34 grades by keyhole along introducing arrow 35 directions just enough for this reason, and this makes that this operated position of lockable mechanism 13 is at least temporarily fixing.This finds out by the fixed point 36 between the inner limit of the guide 12 in lockable mechanism 13 and the rotor 11 that in Fig. 3 described guide for example can be made with ice crystal (Eiskristallen).This moment, spring carried 14 inoperative.Rotor 11 is turned round once more along reverse flip shown in Figure 3 reverse 26.Because lockable mechanism 13 temporarily is fixed in the position of this operation in stator 11, the keyhole 22 under rotor can turn over, and fixing lockable mechanism 13 is radially shifted out because of spring carries 14.So rotor 11 has also arrived the opposed operating position of having described by Fig. 2 11.2, should be able to implement the major function of the equipment of being attached troops to a unit in this operating position.Then must be in a kind of lock 11.2 carry out release in the operating position.Therefore should point out that the mechanism by operation and fixation in known devices 10 ' still can finally pry open corresponding lock by described back

rotation

25,26.

This is avoided by a kind of simple suitable partially measure in the present invention, shown in Fig. 4 to 7.Here only provide difference, others as previously mentioned.

A main difference part of the present invention is that according to Fig. 4, the rank of a side 23 of sensing reverses direction are high different with the opposite side 24 of pointing to reverse flip direction 26.That is, in device 10, at lockable mechanism 13 positions a passage expansion section 40 is set in stator 21 at least.Therefore there are a combination passage that constitutes by keyhole 22 and passage expansion section 41, this combination passage itself to be highly abnormity at this place.Here should mention that the whole side of the sensing reverses direction of this combination passage can be divided into the side section 37,38 of rotation dislocatin, only is provided with two in this example.See that radially the lateral surface section has constituted aforesaid first side 23 of keyhole 22, the front said that its degree of depth was more shallow.Other side section 38 of this combination passage is positioned at the inner end of passage expansion section 40.Two section 37,38 span 47 mutual rotation dislocatin that pass through passage expansion section 40 here.This passage expansion section has increased a clear span 41 than the actual cavity of rotor 11.But this clear span is compared with the keyhole 22 whole clean dark 42 that can find out on opposite side 24 and is designed more smoothly, as shown in Figure 4.The keyhole degree of depth 42 is determined by the difference in height between passage substrate 39 and the cylindrical side face 17 substantially.

Obviously, in device 10, rotor 11 can have only a lockable mechanism 13.But install the lockable mechanism 13 of the 10 subtend convex shoulders 19 that have gang to have usually to be misplaced highly mutually.Passage expansion section 40 only is arranged on one of these lockable mechanisms and goes up just enoughly, and other position of the rotor 10 that occupies at other lockable mechanism can be designed by known way.If a sheet system has eight lockable mechanisms, wherein passage expansion section 40 is positioned in the manufacturing or on the space favourable as far as possible position.Can use first lockable mechanism or last lockable mechanism, but whichever all occupies 19 pairs of particularly advantageous height and positions of safe effect of its subtend convex shoulder, also will further describe this safe effect below for this reason.For the manufacturing technology reason, also can adopt the top of this lockable mechanism family or rearmost one group.All lockable mechanisms 13 of yes especially reliably this family all are provided with this passage expansion section.The radially clear span 41 of aforementioned increase in case of necessity also can all be designed to difference to each lockable mechanism.

Fig. 5 shows device 10 of the present invention, and it is in an operated state, illustrates by known devices shown in Figure 3 10 ' and describes.In Fig. 6, arrived the position of rotation shown in unobstructive operating position 11.1 itself along rotor 11 aforesaid reverses direction 25 by operated lockable mechanism 13 always, but significantly different with the similar state of known devices 10 ' shown in Figure 3.In device of the present invention, as shown in Figure 6, operated lockable mechanism 13 has clinged on the bearing surface 44 in the sensing of passage expansion section 40.At this moment, lockable mechanism 13 stretches out the side face 17 of rotor 11 with a termination 43.If similar Fig. 3 implements to fix 36 by a kind of cold spray or similar approach now, then do not realize whatever, as shown in Figure 7.

In Fig. 7, shown in fixed point 36, the lockable mechanism 13 shown in Figure 6 operated position that radially is misplaced in rotor 11 is at least temporarily fixing.Then, rotate if a kind of pressure of reverse flip direction 26 is implemented in the 11.1s, unobstructive operating position that also can find out from Fig. 7, then operated lockable mechanism 13 has kept off on opposed second side 24 of keyhole 22 with its termination of stretching out 43.Hindered rotor 11 from zero position shown in Figure 7 being rotated further along empty arrow 46.Operating position 11.2 can't reach by above-mentioned destruction methods.Device 10 of the present invention is antitheft.

Providing in this case, the radial depth 41 of passage expansion section 40 is constant with respect to the width 45 that holds only by shown in Fig. 7 middle chamber constant at this place, and this holds width 45 is to be determined by the cylindrical side face 17 of rotor 11.Bearing surface 44 in passage expansion section 40 is also basic coaxial with rotor axis 20.But also can be arranged to abnormity in case of necessity.

Further describe by Fig. 6, preferably passage expansion section 40 is seen along reverses direction 25 and has been embodied as a passage span 47, and this span is put angle 48 between farthest the operating position 11.1 greater than zero position 11.0 and range zero.
