Fig. 3 illustrates 5 rotatable lock core pins 25 that are inserted in its lock core pinhole 23.As hereinafter describing in detail, lock core pin 25 can center on its lock core pin rotational and move axially in lock core pinhole 23 when the engagement that is subjected to key.The free amount of spin that one projection that moves in dimple 24 only, 26 restriction lock core pins 25 are arranged on the lock core pin as mentioned above.
Fig. 5 is the stereogram of an embodiment of a rotatable lock core pin 25.Can see that rotatable lock core pin 25 is made of three parts: cotter way engagement end face and formed integrally therewith but rotated a main part 32 of end face by the pin that a central part separates is arranged on it; The one master collet portion 34 and that is enclosed within on this central part is enclosed within the sleeve packing ring 35 that pin rotates on the end face, can freely rotate relative to this sleeve part 34 of rotatable lock core pin 25.
Cotter way engagement end face 37 is towards keyhole 22, and pin rotates end face 38 towards the outer circumference surface of lock core 16 and can be by suitable rotational lock core and towards through hole 20 and alignment with it.
The shape of cotter way engagement end face 37 is before rotating 180 and symmetrical afterwards.But as hereinafter describe in detail in conjunction with Figure 27, the shape of cotter way engagement end face 37 is preferably made non axial symmetry, thus through rotating unspecified angle so that asymmetric when a corresponding rotatable joggle piece that a cotter way makes up changeable key 12 meshes.
The cotter way engagement end face of rotatable lock core pin 25 is preferably projection, as it is then better to be the cutter head shown in Fig. 5 and 25.The size of this cutter caput is made in the engageable groove on the rotatable joggle piece of following key.Also can be as hereinafter in conjunction with as described in Figure 10, fluting on the cotter way engagement end face 37 and with the rotatable joggle piece of key on a projections mesh.
Shown in Fig. 2 and 3, pin rotates on the end face 38 preferably has groove 39 and so on so that rotation cotter way end of engagement face 37 as described below.
As mentioned above, sleeve part 34 can rotate relative to cotter way engagement end face 37 in the time spent of doing that is subjected to enough big power, and this describes in detail hereinafter.This is as described below preferably unrestricted and be convenient to combination with instrument change cylinder lock 10 on the orientation around relatively rotating of lock core pin axis.
As mentioned above, sleeve packing ring 35 is enclosed near sleeve part 34 on the pin rotation end face 38.Sleeve packing ring 35 does not connect with the remainder of rotatable lock core pin 25 and can freely rotate relative to sleeve part 34.The effect of sleeve packing ring 35 is hereinafter handed over.The one suitable biasing mechanism of spring pin 40 as shown in Figure 2 and so on is used for a sleeve packing ring 35 and setovers to keyhole 22 directions.
Can see clearly especially from Fig. 2 and 4, cylinder lock 10 has the side chain spare of side slat 41 and so on to be used for optionally fixed lock core 16 and it can't be rotated relative to circular cylindrical shell 14 around axis 21.For example can be as can be seen from Figure 7, this fixedly is because side slat 41 straddles in the side slat slot 18 of the side slat slot 19 of lock core and circular cylindrical shell when not having suitable key to insert in keyhole 22.
Can know from Fig. 4 and to see, have on the side slat 41 with its on nicked sleeve part 34 arranged each rotatable lock core pin 25 projection 42 one to one.As can be seen, projection 42 can replace hereinafter in conjunction with Figure 10 and 11 described grooves.
The size of side slat projection 42 is made in the axial cut-outs 36 of the sleeve part 34 that can insert corresponding rotatable lock core pin 25.The corresponding length that axial cut-outs 36 cans be compared to projection 42 most is the longest slightly, thus only when projection 42 and otch 36 accurately align in rotation direction with axially projection 42 could insert in the otch 36.This requirement makes lock of the present invention in fact can not be opened by sledge, thus the safety that has improved this lock greatly.
Thereby the position of each projection 42 and shape make the turned position of rotatable lock core pin 25 when the rotatable lock core pin 25 of correct a changed key 12 engagements and axial location make side slat can withdraw from the side slat slot 18 of circular cylindrical shell can be in circular cylindrical shell 14 rotational lock core 16.
In some cases, can open the key of a plurality of locks, require to do the width of one or more axial cut-outs 36 widelyer than inserting required width for corresponding projection 42 in order to use master key.Also can use a more than axial cut-outs 36 and be used for master key.
Should see that the shape of side slat 41 needn't be as implied above and described.For example, side slat can become side pin or other one or more parts that can play same purpose.All these parts should be regarded as and be included in this manual and employed side slat of claim and side chain spare one speech.
Figure 10 and 11 illustrates the another kind of engagement system of side slat and lock core pin.As mentioned above and as shown in figure 11, another embodiment of side slat 100 does not use projection 42 shown in Fig. 1-6 embodiment and uses side slat groove 101.The size of side slat groove 101 is made and can be inserted for the pin projection 102 of the axial cut-outs 36 among the embodiment shown in Figure 10, as to replace Fig. 1-6.Side slat groove 101 and pin projection 102 with the embodiment of Fig. 1-6 in axial cut-outs 36 mode identical with side slat projection 42 intermesh.
Figure 14 example illustrates the present invention one can change key 12.Key 12 comprises a key bit 50 and a shaft 52.One or more rotating cotter way engagement end face joggle pieces 54 are arranged on the shaft 52, and Figure 14 illustrates 5 cotter way engagement end face joggle pieces.Can shown in label among Figure 16 56, slot on the rotatable cotter way end of engagement face joggle piece 54 or make projection shown in label among Figure 15 57 and respectively with the rotatable cotter way end of engagement face of lock core pin 25 on projection or groove fit.
Each rotatable cotter way end of engagement face joggle piece 54 is designed to and can meshes with the corresponding cotter way engagement end face of rotatable lock core pin 25.For example, for rotatable lock core pin embodiment shown in Figure 5, the size of the cutter head of the cotter way of rotatable lock core pin 25 engagement end face 37 is made in the cotter way engagement end face joggle piece 54 that can insert suitable fluting as shown in figure 16.Equally, for the cotter way engagement end face of fluting shown in Figure 10, the size of the fluting portion of lock core pin 25 is made and can be inserted for the projection 57 of joggle piece.
Rotatable cotter way end of engagement face joggle piece 54 preferably is the sort of U-shaped or the special-purpose circlip shape that Bossard of Switzerland and Seeger ofGermany is sold.
According to one embodiment of the present invention, in the dimple 58 that is preferably circle of each rotatable cotter way end of engagement face joggle piece 54 close fit on the shaft of key 12.Rotatable cotter way end of engagement face joggle piece 54 in dimple 58 tight fit and the elasticity of rotatable cotter way end of engagement face joggle piece 54 and outwards biasing only be chosen to just can in dimple 58, rotate during above certain threshold value when the rotatory force that is applied with screwdriver and so on instrument as described below.
According to one embodiment of the invention, thereby thereby carry out punching press at next-door neighbour's dimple 58 positions of key shaft and form lock prominent 59 and make a part of key materials embed the cotter way combination of this key of locking mesh part in the joggle piece 54 in that dimple 58 is other in case set and just can't rotate at these positions.Figure 17 illustrates because of carrying out the projection locking that punching press forms.Can remove lock prominent 59 and can be with instrument 60 (Figure 12) when needing as can be seen, from new change cotter way combination.
The working condition of the lock ﹠ key combination of illustrated embodiment of the present invention is as follows.From Fig. 5 and 10 respectively as seen, each rotatable lock core pin 25 meshes between the axial cut-outs 36 of the axis of the axial projections of end face 37 or groove and sleeve part 34 or the projection 102 at cotter way a changeable angle Z.
The orientation of the rotatable cotter way end of engagement face joggle piece 54 on the one correct key 12 makes the cotter way engagement end face 37 of when a key 12 all inserts in the keyholes 22 each rotatable lock core pin 25 and sleeve part 34 1 causes rotate and is positioned to guarantee corresponding cotter way end of engagement face joggle piece 54 correct engagement that turn on the projection of cotter way engagement end face 37 of each rotatable lock core pin 25 or groove and the key 12 automatically.
The correct location of rotatable lock core pin 25 makes the otch (Fig. 5) of rotatable lock core pin 25 or projection 102 (Figure 10) over against side slat 41 respectively shown in Fig. 3 and 11.
Thereby if key 12 rotates around lock core axis 21 lock core 16 is rotated around axis 21, then the inclined-plane of dimple 18 and side slat 41 with dimple 18 over against the inclined-plane make side slat 41 inner and move to rotatable lock core pin 25 to lock core 16.Because otch 36 or projection 102 be correctly alignment all, so the groove 101 of the pin projection 102 insertion side slats of the projection 42 insertion otch 35 of side slat 41 and/or rotatable lock core pin 25, thereby side slat 41 can move to lock core axis 21.This of side slat 41 moves and makes it can withdraw from circular cylindrical shell side slat socket 18 fully, thereby lock core 16 can center on 16 rotations of lock core axis and can open this cylinder lock in circular cylindrical shell 14.
As what insert keyhole is an incorrect key, then one or more otch 36 or projection 102 can not alignd, thereby can't realize inserting engagement between the sleeve part 34 of side slat and lock core pin 25, thereby the part of side slat 41 can be stayed in the circular cylindrical shell side slat socket 18, thereby lock core pin 25 can't rotate in circular cylindrical shell 14.
Best following carrying out in the time will changing the combination of cylinder lock 10: at first shown in Figure 12 and 13, cylinder lock 10 is pulled down so that expose the through hole 20 of circular cylindrical shell 14 from door or other installation components.One correct key 12 is inserted in the keyholes 22 and lock core 16 can be rotated in circular cylindrical shell 14.
If structure shown in Fig. 3 and 13 is rotated about 180 ° and make through hole 20 rotate end face 37 over against the pin of rotatable lock core pin 25 as shown in figure 13 to lock core 16 then.The pin that passes through hole 20 with the instrument 60 of screwdriver and so on then and insert rotatable lock core pin 25 rotates in the groove 39 of end face 38.Because sleeve packing ring 35 is hollow, so screwdriver and so on instrument can insert in the groove 39 that pin rotates end face 38.
Turning tool 60 and cotter way engagement end face 37 is rotated relative to sleeve part 34, and sleeve part 34 is inserted in owing to the projection 42 of side slat 41 in the otch 36 of sleeve part 34 and can't rotate relative to lock core 16.
Should see the corresponding rotatable cotter way end of engagement face joggle piece 54 of also key 12 and rotatable lock core pin 25 the simultaneously cotter way engagement of the rotation of instrument 60 end face 37 engagements.Like this, the combination of key 12 simultaneously, similarly change with the combination change amount with cylinder lock 10 automatically.
Like this, can rotate into any required angle to otch 36 or the angle between the projection 102 that cotter way meshes end face 37 and sleeve part 34.For ease of setting suitable angle, around each through hole 20, can be carved with scale 70 (Fig. 6) on the external surface of circular cylindrical shell 14, and instrument 60 can be carved with scale 72 as shown in figure 13.Certain scale 70 on the housing alignd with the scale 72 on the instrument can set each reproducible angle.
For ease of alignment, can use the magnifying glass 74 that correctly to focus or other Optical devices to make that the user is clear to see scale.Magnifying glass 74 preferably is contained on the instrument 60 and carries out alignment procedure so that correctly focus.
The possible number of combinations of each cylinder lock is very big.For example, if only use 12 different angles on each pin of 5 pins as shown in Figure 6, the possible number of permutations just reaches 12
5Or 248,832.If will increase angle number and/or the pin number that the number of permutations can improve each pin.
Also can use the mutually different pin of length, thereby corresponding rotatable cotter way end of engagement face joggle piece recessed degree in key is also different.Fig. 8 illustrates a such embodiment, and wherein, the length of rotatable lock core pin 125 is different, and the height of the external surface of the shaft 152 of each rotatable cotter way end of engagement face joggle piece 154 relative key 112 is also different.Fig. 1-6 illustrated embodiment also can be used the mutually different pin of length, and sleeve packing ring 35 is determining the maximum length of the corresponding length that equals side slat projection 42 of otch 36 at this moment, thereby requires the axial location of lock core pin 25 very accurate.
Key of the present invention can only have rotatable cotter way end of engagement face joggle piece on one side, but also on the two sides rotatable cotter way end of engagement face joggle piece is arranged all.As mentioned above, the combination of one group of rotatable cotter way end of engagement face joggle piece changes automatically along with the change of the combination of cylinder lock.
When needing, rotatable cotter way end of engagement face joggle piece on this key another side and the rotatable cotter way end of engagement face joggle piece change easily as shown in figure 18 on any secondary key one or both sides.One instrument 161 identical with instrument 60 (Figure 12) is used for rotatable cotter way end of engagement face joggle piece 54 is turned to desired location.For accurate engagement in rotation part 54, the shaft 52 of key 12 peripheral part of rotatable cotter way end of engagement face joggle piece 54 can be carved with circular cylindrical shell 14 on the identical scale of scale 70 (Fig. 6).
Be further accurately to rotate rotatable cotter way end of engagement face joggle piece 54, on each rotatable cotter way end of engagement face joggle piece 54 preferably just like shown in Figure 14-16, the recess 58 that in alignment procedure, uses.As on the instrument 61 as described in the top combination tool 60 magnifying glass 174 being housed preferably.
The microspike (not shown) that a succession of spaced apart is preferably arranged on the circumference of each rotatable cotter way end of engagement face joggle piece 54.In the engageable corresponding spaced apart dimple (not shown) on dimple 58 inwalls of these projections.These projection cards crash tightly snap in for one in these dimples and rotatable cotter way end of engagement face joggle piece be engaged in the dimple 57 more tightly just can duplicate a kind of combination on the key more accurately one.
This can use equally on rotatable lock core pin 25 and obtain same advantage, and the microspike (not shown) in the corresponding dimple that can snap in corresponding pinhole can be arranged at least a portion of lock core pin.
Above-mentioned basic embodiment only depends on side slat and lock core can't be rotated in circular cylindrical shell.In another embodiment of the present invention, also can or also can use drive pin, insert when it does not have correct key to insert in keyhole in the circular cylindrical shell and prevent that lock core from rotating relative to circular cylindrical shell.
Shown in Fig. 7 and 8, this another embodiment has used drive pin 180.Have in the circular cylindrical shell 181 position and lock core pinhole 183 over against circular cylindrical shell pinhole 182.The position of circular cylindrical shell pinhole 182 and size are made and can be inserted for drive pin 180.
As shown in Figure 7, when not having correct key 186 to insert in the keyhole 188 drive pin 180 crossovers in lock core pinhole 183 and circular cylindrical shell pinhole 182 and lock core 116 can't be rotated relative to circular cylindrical shell 181 around lock core axis 121.

Be applicable to shown in above Figure 14-16 that the key that the present invention one can change cylinder lock is the also changeable key of its combination.But in some cases, require to use it to make up immutable but flat key permanent fixation during fabrication.The flat key of this class still is much better than existing Medeco type key part and is still can use a large amount of different angles, and does not resemble the angle (being generally three kinds of angles) that can only use the existing Medeco type key seldom.
Figure 25 illustrates its example that makes up unmodifiable flat key.Have on the key 212 one or more its sizes make can with the fixing groove 213 of direction of the cutter head engagement of each rotatable pin of that class cylinder lock shown in Figure 24.These cutter heads are preferably axially not symmetrical, thus the shape difference after in 360 °, rotating arbitrarily.
The program that makes up the combination that changes the cylinder lock ﹠ key under the unmodifiable situation simultaneously at the cotter way of key with in conjunction with Figure 12 and 13 described identical, to have a key in the key that can change cylinder lock at least be that combination shown in Figure 14 can the change type as long as open.But,, make its correct unmodifiable key of combination shown in Figure 25 in addition rather than the key shown in Figure 180 of method that a kind of change can change the combination of key be shown with regard to available any appropriate process in case set up a kind of new combination.
In order further to improve the safety of cylinder lock arrangements of the present invention, the key of preferably guaranteeing to be used for to open this lock can't duplicate with existing technology and common key blank.For this reason, one embodiment of the present invention proposes, and each key comprises at least one floating part, and the effect of this floating part and structure are hereinafter handed in conjunction with Figure 19-23.
Figure 19 and 20 is respectively the end-view and the lateral view of a cylinder lock identical with cylinder lock shown in Fig. 7 and 8, and promptly it comprises drive pin.Obviously can find out, also can use that class shown in Figure 3 not have the cylinder lock of drive pin.
The key 312 that is used for opening cylinder lock shown in Figure 19 and 20 is with the difference of key shown in Figure 14, be used for meshing have at least in the parts of rotatable lock core pin 325 parts can be in the certain displacement scope relatively key 312 move up and down.
Figure 19 and 20 and the partial enlarged drawing 21 of Figure 20 in, key 312 has only a unsteady cotter way engagement end face joggle piece 330.As can be seen, any one or a plurality of cotter way engagement end face joggle piece can become unsteady cotter way engagement end face joggle piece.Other axial locations that can center on the joggle piece 340 of its rotational are as mentioned above fixed.
Contrast with joggle piece 340, can but needn't be around the axial location of the unsteady joggle piece 330 of its rotational fixing and can " float ".Therefore, for example, unsteady joggle piece can comprise that one enlarges flange 350, and this flange can slide between the primary importance shown in Figure 21 and the second place in a wicket, and in the time of on the second place, flange 350 moves up up to against a holding part 360.
Holding part 360 is preferably a circlip or other the outwards spring or the spring-like mechanism of biasing, thus for example when changing the combination of cylinder lock such as rotatory force be no more than predetermined threshold and just floating part be fixed into and can't rotate.In certain embodiments, unsteady joggle piece is not rotatable.At this moment, its rotational orientation is just fixing during fabrication.
" amount of floating " of joggle piece 330 of floating set for: stretch out outside the surface of key 312 when the joggle piece that floats leaves float farthest the time part of joggle piece 330 of key 312.
In the embodiment of Figure 19-23, lock core 364 is with the difference of above-mentioned lock core, and for example bias spring 368 and so on suitable mechanism offset pins 366 of radially setovering inwards of usefulness is arranged in the lock core 364.
In order to prevent that unsteady joggle piece 330 from rotating unintentionally, the shape of unsteady joggle piece 330 can be as shown in figure 21, thereby as do not rotate rotating holding part 360 joggle pieces 330 that float simultaneously and just can't not rotate, and holding part 360 only just can rotate when surpassing the rotatory force of predetermined threshold when being subjected to one.
During work, insert key 312 as mentioned above, but the joggle piece 330 that floats is pushed to key 312 and allows the key 312 correct keyholes that insert.When unsteady joggle piece 330 arrives its precalculated positions, offset pins 336 be used for radially promoting inwards floating joggle piece 330 and make float joggle piece 330 and lock core pin 325 as Figure 19 and 21 be shown in outside the plane of defining on key 213 surfaces and firmly mesh.
Unmodifiable as shown in figure 24 key 212 also can with one its make up unmodifiable cylinder lock and be used.As shown in figure 24, thus the angle X that the pin of this unmodifiable cylinder lock 380 is made of single-piece between the cutter 330 of axial cut-outs 386 and this pin is fixing during fabrication.The lock core pin (Fig. 5) that this whole structure can be employed with the cylinder lock embodiment of its cotter way shape variable, be made up of relatively turnable three parts is made comparisons.
