Abstract

The invention relates to a locking system comprising a lock and a number of keys which fit one lock. The appropriate keys which can be inserted into the lock channel have differing lock codes which actuate the locking mechanism of the lock. It is proposed that, in order to improve the security of the lock, each lock code should have allocated to it its own unique independently operated lock mechanism.

Description

By lock and many handles is a locking device that phase-locked key of joining is formed

The present invention relates to a kind of is a locking device that phase-locked key of joining is formed by lock and many handles, wherein, can insert the phase bitting in the key selectively, has the locking coding of the locking mechanism of the operated lock that differs from one another.

The known many form of structure of the locking device of the above-mentioned type.Can finish main locking task by means of this locking device.In a kind of master key system, in certain crowd, respectively distribute a single key, this single key is always only joined an independent lock.But can handle whole locks of master key system by means of master key.Can for example relate to the magnetic code key about key, it makes and sells co-operation with the magnetic lock of lock.Flat key also is a prior art, and this key is shaped on the locking otch of the locking pin that is used to arrange lock core in their wide side or on their narrow limit.Yet the shortcoming of this locking device is the following fact: can find out main locking coding from the many single key that exists, thereby reduce the safety of this locking device.

The objective of the invention is to design a kind of locking device of the above-mentioned type simple in structure, make it to improve safety, by existing secondary key, that is single key, can not find the locking coding of master key.

In this class locking device for achieving the above object, in lock be automatic manipulation alone of every kind of locking coding configuration and only be tuned to wherein a kind of locking mechanism of locking coding.

According to such design, the safety that has improved the above-mentioned type locking device.What are no matter have the quantity of the secondary key of locking coding, the locking coding of master key all can not be found.Because every kind of locking coding of a key all disposes a locking mechanism alone.When inserting relevant key, can only handle this locking mechanism.Other locking mechanism is unaffected.Therefore the locking coding is irrelevant each other, so people also just can not calculate or find out the locking coding of master key.

About locking device can relate to a kind of locking pin of magnetic of the locking mechanism that has magnetic code and handled by its, locking mechanism is by moving operating contact maker when the key that insertion matches.Eminency of the present invention in this case is, every key only has coding at part surface, remaining part surface does not have the locking coding, and a gulde edge arranged, it just is used to force locking mechanism displacement, and with do not have the locking mechanism that locking coding local surfaces matches on the key and keep motionless.The key card that its part surface contains the locking coding is used as key.This part surface and the locking mechanism that matches with it are overlapping when key is inserted, and arrange the locking pin of magnetic, thereby can drive relevant locking mechanism by the gulde edge in this part surface front.Another part surface is no locking coding.It does not apply any influence to the locking pin.This locking mechanism still keeps locking.That is to say that always when a locking mechanism reach, another locking mechanism is not driven.Can also relate to the coding of other types about key, for example be tape or punched card in form.Especially this solution security advantage of tape is very outstanding, because the easiest identification of hole coding, and, the easiest analysis when on an object, having major and minor key.

Favourable being improved to, locking mechanism are designed to be equipped with the slide block arranged side by side of magnetic lock cotter, are shaped on vacancy on the key, are used to insert the engages stop of this locking mechanism slide block, this slide block and the part surface phase configuration of not having the locking coding on the key.Corresponding lock this turned out to be reliable structure thereby kept.Slide block only separates by a boundary seam along its direction of motion.According to the size of locking mechanism slide block, also can determine the size of that part surface that contains coding of key.If key is inserted, then its locking coding is arranged the magnetic lock cotter of that relevant locking mechanism slide block.By gulde edge in the part surface front that coding is arranged, act on power on the engages stop of locking mechanism slide block, therefore this locking mechanism slide block is driven bonding station.But another locking mechanism slide block is slack, is not shaped on a vacancy because there is the part surface of locking coding on locating surface, so engages stop is inserted in this vacancy when key is passed forward.

In addition, thought of the present invention can be incorporated in the locking mechanism with rotating lock core cylinder, and this lock core cylinder is equipped with the locking pin, and they are arranged in unlocked position by the locking otch of the formation of key coding.Essence of the present invention in this case is, be provided with two lock core cylinder parts that respectively constitute a locking mechanism, they respectively are equipped with lock set cotter, and after each half key adaptive with one was neat with the locking pin row, lock core partly can move on to a bonding station with driven member.Be equally in this case, by locking coding, that is can not find out the locking coding of master key by the locking otch of secondary key, it doesn't matter between just the coding of single key and master key were encoded.This locking mechanism system partly is made up of two lock core cylinders now, and wherein each lock core cylinder partly has row's locking pin.Can the locking pin row of this or another lock core cylinder part is neat with corresponding half key, and then this lock core cylinder transposition of partial that just can release arrive the bonding station with driven member.Another lock core cylinder part state that then still keeps Locked.

Favourable way is, with the semicylinder of two lock core cylinder partial design for engaging one another along a longitudinal joint, is furnished with lock set cotter on each semicylinder, for they are equipped with the phase distribution of middle casing, these two semicylinders respectively have a vertical key guide groove that separates, and can move on to respectively vertically and the driven member position engaged by means of key, wherein, middle casing is contained in the shell rotationally.This means, after corresponding half key is inserted, just can carry out locking and handle.Will all not insert by two and half keys for handling.If inserted wherein one half key, then the locking otch by means of it comes into line the locking pin, and thereby makes that relevant lock core cylinder partly be displaced to release under the situation of bonding station at it.Can realize rotatablely moving by means of this half key now.This rotatablely moves and is partly passed to middle casing by other that by the lock core cylinder of locking, so this middle casing is and then moving in the shell transfer.

This has proved favourable way, and driven member is bearing on the rear side end wall of shell, and it has the non-circular cross section that is used for the projection engagement of lock core cylinder part.The engagement cross section complementation of two projections and the non-circle of driven member.One of them projection inserts in the driven member engagement cross section just to be enough to serve to spur.

By another kind of scheme also can be, two lock core cylinder parts are contained in vertically continuously in their set middle casings, a lock set coremaking pin respectively is equipped with and, they and the co-operation of distribution mutually of middle casing, wherein, lock core cylinder partly has the vertical key guide groove aligned with each other at the different length key, can mobile lock core cylinder part by means of these keys, reach the purpose that is in the driven member position of engagement, wherein, middle casing is contained in the shell rotationally.In this case, also it doesn't matter mutually for the locking of key coding.By for example encoding and derivation to encode than the locking of long key than the locking of short single key.If for example insert this short key, then it is listed as relevant locking pin row, and allows this lock core cylinder partly to move so that engage with driven member.When using that long key, also realize this situation.This key be passed in the inserting side lock core cylinder part vertical key guide groove and insert in vertical key guide groove of another lock core cylinder part, locking pin row there is neat, so, and then just can move this lock core cylinder part.

The further design of this scheme comprises, dorsal part in lock core cylinder part key inserting side has a blade that extends radially, be used for moving the transmission lath of a middle casing that is attached thereto, and middle casing is rotatably connected therewith, this transmits lath preceding a distance of that lock core cylinder radial system moving plate partly in the inside on the throne and stops, and this lock core part stretches in the engagement cross section of driven member with a non-circular projection.This braking blade will be inside that lock core cylinder pin and do not allow its rotation.When using that weak point key, when the lock core cylinder in the inserting side moves, its blade that extends radially is transmitting power of effect on the lath, and this transmits lath and acts on the brake(-holder) block after through an idle stroke, makes a recess disengage from of brake(-holder) block and shell.Now, this radial blade and middle casing inside are rigidly connected, so its rotation passes to that lock core cylinder of drive driven member inside.Moving of the lock core cylinder part of the inside of carrying out by means of long key causes brake(-holder) block rotation release equally, so driven member be rotated and be driven to the lock core cylinder part can attaching troops to a unit in its middle casing.

Suggestion is in addition transmitted lath and is provided with a control boss, it and the trip bolt co-operation of inner middle casing.When using short key to make the reach of transmission lath, trip bolt places the off-position by the control boss.This trip bolt prevents from owing to insert aid in vertical key guide groove lock core cylinder inside partly to be rotated with middle casing.Always allow to use the key that conforms with the regulations, handle so that can carry out locking.

Again be in the home position that conforms with the regulations after handling at locking, not only brake(-holder) block but also inboard middle casing all are subjected to the active force that the contrary connector of a compression spring meshes direction.

For increasing changeability, locking mechanism can be taken out and pack into by the present invention's design.There is not encoding relation mutually because belong to the locking mechanism of lock, so can change.No matter be the locking device of carrying magnetic coding key, or its key is provided with in form to the locking device of the coding of locking otch and can so do.In having the locking device of magnetic code, one or two locking mechanism slide block can be extracted out from the shell of lock, and available other replacement.For example, after a construction stage, can take out a locking mechanism slide block, and have the locking mechanism slide block of coding to replace, after being inserted into, irreversibly stay in the shell of lock with another.Just can not locking with the corresponding key of using in the past.This measure provides such possibility,, realizes belonging to the locking plan of a locking system after whole locks have been installed that is, and irrelevant with the locking device of producing in manufactory.

Changeability can also further be optimized, that is, make at least one locking mechanism that a code conversion device is arranged, and it is magnetic pin support movably by means of the key motion in form.It can be designed to the form of revolving part.When using follow-up key, by being in the magnetic pin support of tooth engagement mutually, just can cause step-type rotation, so previous key no longer can use.This point in conjunction with a plurality of locking mechanisms of a lock, is brought additional codifiability again.

The characteristics that are used to handle the key of the locking device that is provided with magnetic code are, a gulde edge of band vacancy that is used to handle engages stop and always only handles the engages stop of a locking mechanism slide block is arranged, wherein, vacancy is with respect to the distance of gulde edge retraction, and the locking mechanism slide block shift motion of handling with gulde edge is suitable.If key inserts the insertion groove of locking device, then drive the engages stop of that relevant locking mechanism slide block, and thereby make it mobile at the gulde edge of the part surface front that coding is arranged.The engages stop of adjacent locking mechanism slide block is then imbedded in the vacancy that bounces back with respect to gulde edge.Because the locking mechanism slide block shift motion that the amount of retraction and gulde edge are handled is suitable, so this engages stop can unhinderedly be imbedded in the vacancy, does not apply power on this engages stop.A key does not have vacancy although be provided with the coding that conforms with the regulations on a part surface, and it can not pass relevant locking mechanism slide block forward so.Also have,, also just can not move forward completely, so can not accomplish the joint sought if the depth design of vacancy gets inadequately.

Another hidden ingredient is that gulde edge and vacancy are arranged on the offset from center place on the key.If the vacancy of the key that will insert is not aimed at the engages stop that it faces, can not reach the combination of being sought so equally.

Can obtain the advantage of operating technology aspect by the following stated: be shaped on mark on one wide of key.For example, this mark can point out it related be single key or master key.This mark can point out that also key is not put upside down the side, otherwise does not allow to cause bonding station equally when implementing to insert.

Should mention also that at last vacancy is positioned at the part surface place of no locking coding.Therefore, there is the part surface of coding can not reduced because of vacancy.

Lock core cylinder part 84 back of key inserting side, design has a blade that extends radially 100.It is used for passing one and transmits lath 101.Transmit lath 101 for settling, an outer cannelure 102 that is located in the middle casing 83 is arranged.Blade 100 is in such situation, that is, when lock core cylinder part 84 moved, it inserted in the outer cannelure 102 with being rigidly connected, and will transmit lath 101 and move towards the direction of a radial system moving plate 103 of lock core cylinder part 85.For this purpose, transmit lath 101 place separated by a distance before brake(-holder) block 103 and stop, brake(-holder) block 103 shapes are inserted in the radial slot 104 of shell 78 suitably when lock is in lockup state.Radial slot 104 is communicated with a ring cavity 105 of shell 78.The compression spring 106 of a truncated cone shape is bearing on cylinder bottom or the end wall 79, and both also loads to middle casing 83 to brake(-holder) block 103.Therefore, that form and prevent this assembly that they rotate mutually by lock core cylinder part 85 and middle casing 83 by the locking pin, can not in shell 78, rotate.

Transmit lath 101 and be provided with radially inside control boss 107 towards an end of brake(-holder) block 103.It and one steady pin 108 co-operation of guiding radially in middle casing 83.Compression spring 109 with steady pin 108 to external pressure.Steady pin 108 is designed to fork-shaped, as shown in figure 15.Yoke 110 is round transmission lath 101, and shape is embedded in the radial slot 104 of shell 78 suitably.The web 111 restriction steady pins 108 of fork outwards move, and are used for and transmit control boss 107 joints of lath 101.Design difference when the front, lock core cylinder part 85 has been under the state that engages with driven member 80 rotation at home position, meshes in the cross sections 113 to a certain degree because the projection of lock core cylinder part 85 inserts driven member 80 112 this moments.For making 85 releases of lock core cylinder part, compare the key 114 that designs longlyer with key 93 with one.Its length dimension is designed to can make it to pass lock core cylinder part 84 and insert in the lock core cylinder part 85 that axially connects.Locking otch 115 made on the narrow limit of the key bar of key 114 is used for arranging the locking pin.

Draw following working method according to this design:

As shown in figure 16, being designed to short key 93 has inserted in the lock core cylinder part 84.Locking otch 116 by key 93 is arranged locking

89,91, so and then lock core cylinder part 84 just can be along moving with respect to middle casing 82 towards inner direction.When moving inward, blade 100 inserts in the outer cannelure 102, has set up with middle casing 83 to be rotationally connected.Meanwhile, pass transmission lath 101 vertically by blade 100.Control boss 107 makes steady pin 108 and shell 78 disengage from.In addition, by transmitting lath 101 brake(-holder) block 103 of lock core cylinder part 85 is moved, and thereby lock core cylinder part 85 is

moved.Locking pin

90,92 also works to drive middle casing 83 simultaneously.In this position that moves forward, brake(-holder) block 103 is in the annular chamber 105 of shell 78, and therefore, rotatablely moving of key 93 passes to middle casing 83 by blade 100, and by the there locking

90,92 pass to lock core cylinder part 85, the latter drives driven member 80.

Can only rotary cylinder lock core part 84 and thereby also rotatable middle casing 82 by means of an aid.Change middle casing 83 but can not be with.If opener inserts in vertical key guide groove 88 of lock core cylinder part 85 always, then owing to brake(-holder) block 103 and steady pin 108 are arranged, so it can not rotate.Even when the assembly of being made up of middle casing 83 and lock core cylinder part 85 may be moved axially because steady pin 108 still keeps meshing with shell, thus the shell locking rotatablely move.

Therefore, it is just possible that the manipulation of lock only relends the key 114 that helps design longly.When this key 114 was inserted, it passed vertical key guide groove 87 of inserting side lock core cylinder part 84, afterwards, inserts vertical key guide groove 88 of follow-up lock core cylinder part 85.The locking otch 115 of key bar one side is arranged locking

90,92, thereby lock core cylinder part 85 can be along the longitudinal movement by key is top.When this vertically moved, the brake(-holder) block 103 of lock core cylinder part 85 left radial slot 104, and entered in the annular chamber 105 of shell 78, as shown in figure 17.Can rotate driven member 80 by means of lock core cylinder part 85 then.This rotational motion passes to lock core cylinder part 84 equally and attaches troops to a unit in its middle casing 82.

After extracting key, taper compression spring 106 is sent relevant member back to home position.

Can change middle casing 82, need only the transverse holes 95 ' insertion of passing the shell 78 that feeds inner annular groove 95 with an instrument, and pin 94 is pushed back.
