Definitions
- the invention relates to a lock cylinder, in particular a programmable lock cylinder, and to a method for programming a lock cylinder.
- Locking cylinders include a non-rotatably mountable stator (sometimes called a “cylinder housing”) on a lock and a rotor (sometimes called a “cylinder core”) rotatable upon insertion of a mating key about the axis of the lock cylinder. By rotating the rotor drive means are moved, which serve to actuate a bolt or other related to the desired function of the lock cylinder means.
- the rotor is an inserted into the stator cylinder with a plurality of bores extending through the rotor and the stator, and in each of which a tumbler, a Gegenzunnen and a coil spring are used. Guard locking and counter-locking are movable along the bore axis and acted upon by the coil spring with a restoring force. When a key suitable for the lock cylinder is pushed into the lock cylinder, the tumblers position themselves in this way.
- a separating gap (dhiA the separating surface, parting line or separating point) formed between tumbler and counter-locking coincides with a parting line (ie the parting surface / shear surface) between the rotor and the stator. So it comes the tumbler completely in the rotor and the Gegenzurois completely in the stator to lie. This allows rotation of the rotor within the stator and thus can enable unlocking of a locking system.
- Locking cylinders are typically manufactured individually, so that each of the tumblers has a length matched to an associated key. The lengths correspond to the coding introduced in the key, which manifests itself in depressions of different depths in defined (and scanned by the respective tumbler) position on the key.
- programmable lock cylinders are e.g. from EP 2 152 986, WO 2007/05051 1 A2 and US 2003/0084692 A I.
- the US 3,190,093 shows a locking system for Zacken Simplyl, in which the lock cylinder is initially programmed to a temporary key.
- the lock cylinder has at a position a special tumbler Gegenzuariasfar, wherein the tumbler has a sleeve and an insertable into the sleeve against a frictional force further element, for example. A ball.
- This further element is rounded off to the parting line with the Gegenzuiens out.
- a secondary key with a less deep notch is used at the location of the special tumbler counter-locking pair, the cylinder will lock due to too long tumblers per se.
- the temporary key will not fit anymore.
- this reprogramming system has the disadvantage that only a very limited reprogramming is possible and only in one direction (from a key with a deeper notch to a key with a less deep notch) is possible. Therefore, the system is also not suitable for the concept of first producing a generic, unprogrammed cylinder and only later, for example. On site, to program the cylinder. It is also very delicate, the force necessary for pushing the further element into the sleeve (exerted by a shearing motion) on the one hand not too grow large, without, on the other hand, the connection between sleeve and further element is loose.
- the programming should be easy and / or quick and secure.
- Another object of the invention is. To provide a programmable lock cylinder that is mechanically robust, in particular so that the programming is still accurate even after years of use and / or other mechanical stress. Another object of the invention is to enable a particularly simple programming of a lock cylinder. Yet another object of the invention is to enable a particularly rapid and / or particularly precise programming of a lock cylinder.
- the programmable lock cylinder and / or tools used for programming should preferably be relatively easy to manufacture and meet high safety requirements.
- a lock cylinder of the type described here is a mechanical lock cylinder (which does not exclude the additional presence of electronic rule / electromechanical security features) and has a stator and a rotatable rotor in the stator with a Proföfinung, in which a key is inserted. He further has a plurality of tumbler-Gegenzunes pairs, which are mounted in bores in the rotor or stator, wherein the corresponding bores of the rotor and the stator are aligned with each other when the rotor is relative to the stator in an initial position in which an insertion and removal of a key is possible.
- a tumbler having two parts whose relative position is adjustable and fixable, which are in particular by the two parts are joined together in a press fit.
- a lock cylinder according to the first aspect is adapted to be programmable by a tool which applies a thrust force to the counter-lock or directly to the tumbler to telescope the two parts of the tumbler while pushing a key with the desired coding is inserted into the cylinder and forms a dependent on the coding inside stop for each tumbler.
- the lock cylinder according to the first aspect has an access for the tool, through which the tool, for example.
- the finished assembled state of the lock cylinder in which like a spring pushes the respective Schmidtzuiens inward
- Such an access exists, for example, in one access opening per tumbler counteracting pair with programmable (length-adjustable) tumbler.
- a genetic (programmable) lock cylinder can be made in which tumblers, counter-stops and springs are already mounted and the stator e.g. is sheathed by a sleeve or other housing.
- the two parts of the tumblers are connected to each other (in particular in the press-fit) that the tumblers all have at least such a length as is needed for any key for which the lock cylinder is to be programmable, maximum.
- the tumblers only have to be shortened (by pushing the two parts into one another), that the parting line between the tumblers and the counter-tumblers for all tumbler counter-locking pairs with the parting line coincide between rotor and stator.
- the rotor is then rotatable within the stator;
- the tumblers have exactly the length required for this purpose.
- the tool may have a mechanical stop, which prevents precisely further introduction of the dome into the lock cylinder, when the desired position (parting line between tumbler and Gegenzulets coincides with parting line between the rotor and stator together) is reached.
- a programmable lock cylinder can be created, it being possible for this to be programmable in a particularly simple manner.
- the closing cylinder in addition to said tumbler counter-locking pairs with (at least) two-part tumblers may have further tumbler counter-lock pairs, for example, with ordinary one-piece tumblers.
- a closing effective length of each of the tumblers can be reduced by telescoping the respective first and second parts.
- the closing effective length is the length that measures the tumbler along a bore axis that defines the hole in the rotor in which the tumbler is mounted (in this text the term "bore " is used independently of the corresponding structures ( Holes / cavities / openings) are made, ie it is not limited to a production by drilling).
- the countertop. which is used in combination with the length-adjustable tumbler, which can be adjusted by the adjustable relative position of the first and second parts, may be a conventional one-piece counter-lock in embodiments. Such is particularly sufficient in locking systems with at most medium security requirements.
- a (mechanical) locking cylinder for example according to the first aspect, which also has a stator and a rotatable rotor in the stator with a key opening into which a key can be inserted. It also has a plurality of tumbler-counter-pairs. which are mounted in bores in the rotor or stator, wherein the corresponding bores of the rotor and the stator are aligned with each other when the rotor relative to the stator in a Home position is in which an insertion and removal of a key is possible.
- At least one of the tumblers has a first and a second part, which can be brought into and fixed in different positions relative to each other, and at least the associated Jacobzuanno has a third and a fourth part in different positions relative to each other can be brought and fixable in these, wherein a total effective closing length of the tumbler along an axis of the relative position of the first and the second part depends and a total effective length of the Jacobzuiens along an axis of the relative position of the third and the fourth part depends.
- both the tumbler and the counter-lock are adjustable in their closing effective length.
- first, second, third and fourth parts may be formed and arranged relative to each other at the starting position such that movement of the fourth part relative to the third part by a path length L causes movement of the second part relative to the first part by the same path length L. If such a displacement of the second part relative to the first part causes a shortening of the tumbler by L, can be effected simultaneously so that increases the length of the counter-lock by L - the sum of the lengths thus remains constant.
- the second part may for this purpose be arranged axially with respect to the bore axis within the fourth part and aligned therewith.
- An outside part of the first part may also be aligned with an inside part of the third part.
- first and the third part there may be present between the first and the third part a separation arrangement which is in physical contact with the first and the third part and due to which a plurality of possible parting lines between the first part and the third part are defined namely at least where the
- S eparati onsord tion is in contact with the first part and where the separation arrangement in contact with the third part, and for example, also within the separation arrangement.
- the separation arrangement for example, a plurality of separation elements, which are not or only loosely connected (via a predetermined separation point).
- the second and fourth parts can be aligned with each other and in the axial direction relative to the first and third part - at least inwardly - be displaced, and on the other hand, an outside game of the first part, the separation assembly and an inside game of the third part aligned with each other.
- the second and the fourth part can be arranged radially inside the inside part of the third part (preferably of the whole third part), the separation arrangement and the outside part of the first part, which the second and fourth part surrounded like a sleeve.
- the separation arrangement for example, one or preferably comprise a plurality of rings which are loosely stacked on each other in the latter case or by a detachable connection (in particular predetermined separation point) are interconnected.
- the actual parting line between tumbler and Gegenzuiens is by the - displaceable, i. per programmable - parting line defined between second and fourth part.
- programming may be possible that allows the second relative to the fourth part to be spaced apart, allowing a plurality of different codes to fit the tumbler-antagonist pair (multiple code levels), which is more complex for multiple locking systems a lock-opening keys (so-called Master Key Systems MKS) is usable.
- a programming tool used can act directly on the second part.
- the fourth part may have a passage opening through which the programming tool can also act on the second part, even if the cylinder is already assembled with Gegenzuiens.
- a programming tool of the type described above with reference to the first aspect can then also have at least one programming pin in addition to the mandrels, which is for example guided in the tool and protrudes so far beyond the stop during programming depending on the desired programming that the second part during the Programming is moved to the desired extent compared to the first part.
- a programming pin can, for example, coaxially into the bore be guided insertable in the tool, and, for example, be guided axially through an inner opening in the respective mandrel.
- the programming pin relative to the stop surface of the tool in different positions can be brought, this position, for example.
- the - known - coding of the key is selected at the position of the corresponding tumbler counter-locking pair.
- a stop for limiting a movement of the respective tumbler into the key opening is formed by the respective first part.
- the stop cooperates with a stop in the rotor bore for the tumbler.
- the first parts each have a portion (for example, a cross-sectionally annular portion) in which they fill a cross section of a bore in the rotor, in which the respective tumbler is movably mounted. The same may apply additionally or alternatively, if appropriate, for the third part and / or the separation arrangement.
- a game must remain, through which the mobility of the tumbler is ensured in the opening in the rotor.
- the second parts each have a section in which they completely fill a cross-section of a bore in the rotor, in which the respective tumbler is movably mounted.
- This can lead to an increased mechanical stability and mechanical strength of the lock cylinder and correspondingly to increased safety of the lock cylinder.
- the second part may in this context, for example, be T-shaped or mushroom-shaped. This possibility is at best omitted in embodiments with the separation arrangement, if it is present as preferred radially outward side.
- a stamp (also referred to as a shaft) is formed by the second part, which is inserted into an opening in the press fit adapted thereto opening in the associated first part.
- a punch can be cylindrical and the opening in the associated first part to be hollow cylindrical.
- the first part may, for example, be sleeve-shaped at least on the outside.
- the first and / or the second part may, for example, be rotationally symmetrical, in particular a rotating part.
- the same optionally optionally applies to the third and / or the fourth part and / or the separation arrangement.
- the bores in the rotor or stator are radially, for example, with respect to the axis of rotation of the rotor, which favors in particular the use of rotationally symmetrical parts.
- skewed bore axes are also conceivable with respect to the axis of rotation - depending on the arrangement of the coding on the key.
- an outer filling is formed by the first part and an inner guide by the second part.
- an inner guide is formed by the first part and an outer guide by the second part.
- the third part and the separation arrangement analogously form an outer guide and the second and the fourth part an inner guide - or possibly vice versa.
- the corresponding inner guide outer guide pair can on the one hand ensure a movement of the two parts when programming along the same axis and on the other hand, if necessary (with a correspondingly long version) a strong press fit and thus a great mechanical stability of the connection of the two parts.
- the first and the second part are displaceably connected relative to one another in a press fit.
- the same may be complementary or alternatively in embodiments according to the second aspect for the third and fourth part of the case.
- An interference fit is sometimes referred to as an interference fit. Due to the interference fit, the two parts are so firmly connected that they maintain their relative position even after years of use and other typically occurring mechanical stress. And on the other hand, the length of the tumbler during programming can be adjusted by the applied mechanical Krälte. These forces are so great that the two parts in press fit can be moved relative to each other, which leads to the length adjustment of the tumbler and thus to the programming.
- an artificial material eg an artificial stone, or even a polymer-based plastic, with or without filler
- first, second and optionally third, fourth parts and / or parts of the separation arrangement may consist of the same or completely or partially different materials. Any combinations and permutations are possible.
- first and the second or the third and the fourth part may for example alternatively be made of plastic, for example of a polymer or a polymer composite material.
- the lock cylinder per tumbler-Gegenzunnen- pair a coil spring.
- such plantszurien may have at their respective remote from the keyhole end a recess for receiving the respective coil spring.
- the lock cylinder has a housing, for example a sleeve, which surrounds the stator, and each of the coil springs is in contact with an inner surface of the housing at its end facing away from the key opening.
- the invention also relates to a device having one of the lock cylinder described and a tool.
- the tool may be used to program the lock cylinder and be formed as described in the present patent application.
- it may have a stop surface and at least one protruding from the stop surface mandrel. It can also have several mandrels that protrude the same distance from the stop surface.
- the tool may be characterized in that it has at least one abutment surface and at least one protruding from the abutment surface mandrel, wherein the diameter and length of the at least one mandrel are adapted for programming the lock cylinder.
- the method for programming a lock cylinder relates to a lock cylinder which has a stator and a rotatable rotor in the stator with a key opening into which a key can be inserted. and further comprising at least one tumbler having a first and a second part which are interconnected in a press fit.
- a closing effective length of the tumbler when inserted in the key opening key, in particular by an outside of the Locking cylinder attacking tool, in particular when the key is completely introduced to a key stop, so that each coding is positioned as intended relative to the corresponding tumbler-Gegenzuiens pair, a closing effective length of the tumbler by telescoping or moving apart of the first and second part, reduced in particular by telescoping.
- the tool has a stop surface and a protruding from the stop surface mandrel.
- the mandrel may also be referred to as a rod and causes the telescoping of the first and second parts.
- the spine can be a massive spike.
- the mandrel may be a hollow mandrel (or a hollow rod).
- Such a tool can allow very precise programming, and it can be relatively easy to manufacture.
- the stop surface is flat. However, it can alternatively also have a curvature.
- the mandrel is guided into the stator until the abutment surface abuts against a counter-abutment and a force is exerted by the mandrel on the second part, by means of which the telescoping is effected.
- the said counter-stop is usually formed by a part of the lock cylinder.
- it can be formed by a housing surrounding the stator, for example a sleeve, more precisely by an outer surface of the housing.
- the counter-stop is formed by the stator itself (more precisely, by an outer surface of the stator).
- the said force can be directed in the direction of the key.
- the force can be directed along a bore axis of the bore, in which (or which) is the tumbler in the rotor.
- the abutment surface has a curvature which is adapted to a curvature of the counter-stop.
- stator is encased by a housing (eg sleeve)
- (access) openings can be provided in the housing, through which the mandrel can be passed, so that the mandrel can be introduced through the housing into the stator.
- a parting line between the stator and the rotor there is a parting line between the stator and the rotor, and a length of the mandrel measured from the abutment surface is such that after inserting the mandrel into the stator until the abutment surface abuts against the counter-abutment, the first and second parts are so are pushed into one another so far that an end of the tumbler facing away from the key coincides with the parting line.
- the tool acts indirectly (by the mandrel presses the counterpart or a part thereof against the tumbler) or directly (by pressing on the second part) on the second part, while an inner end of the first part is present at the corresponding coded key. If the parting line between the tumbler and the counter-locking is moved up to the level of the parting line between the rotor and the stator, the locking cylinder is programmed. In particular, the tool carries no information about the coding: it is rather transferred from the key to the lock cylinder in the described method.
- This method can also be applied to embodiments according to the second aspect, in which the counter-locking is in two parts and thus has a third and a fourth part. Then, for example, the tool acts on the second part via the fourth part, ie the tool shifts the fourth part inwards relative to the first part - while, for example, the third part is prevented by the separation arrangement from being displaced inward - and the fourth part shifts the second part inwards relative to the first part, which may be equivalent to a telescoping of the second and first parts.
- a tool in which a programming pin acts directly on the second part to make it spaced from the fourth part - this to define a plurality of parting lines to create a MKS can be.
- a programming pin acts directly on the second part to make it spaced from the fourth part - this to define a plurality of parting lines to create a MKS can be.
- mandrels may be present, which act in the manner described above on the fourth part.
- the two parts Before and after programming and thus before and after the telescoping or moving apart of the first and second parts, the two parts are connected to one another, for example, in an interference fit.
- the telescoping of the first and second part can be done in particular by exerting a force acting in the direction of the key, so that thereby the first and the second part are pushed into each other.
- the first part can be present at the key. Since the first and the second part are already interleaved (interlocked) before programming, the said telescoping of the first and second parts during programming generally corresponds to a further telescoping of the first and second parts.
- the lock cylinder with tumbler and associated counter-locking on the guard and the counter-locking associated coil spring wherein when the telescoping of the first and second parts, the mandrel extends through at least part of the helical spring, in particular extends completely through the helical spring.
- a lock cylinder of course has several tumbler-counter pairs.
- the method described is readily applicable to the case of lock cylinders with two or more tumblers, each with at least two parts.

- Fig. 7 it is also seen that the dome 9a of the tool are inserted through openings in the housing (here the sleeve 7), and that the coil springs then surround the mandrels; the openings in the housing have a smaller diameter than the coil springs, so that the latter can be supported on the inner surface of the housing.
- the spikes 9 a of the tool 9 are inserted through the sleeve 7 into the stator 6, in each case extending through the interior of one of the helical springs 4.
- a force K is symbolized in Fig. 9, by means of which the parts 2a and 2b which are in mutual interference fit are pushed into one another. This leads to the shortening of the length of tumblers 2 which can be seen in FIG.
- Fig. 10 are abutment surface 9b (the tool 9) and counter-stop 8 (Schhesszyhnders 1) in contact, so that by means of the tool 9 no further force for telescoping the two parts 2a, 2b of the tumblers 2 is more exercisable.

- Fig. 16 shows schematically a two-part tumbler 2, in section.
- This tumbler 2 corresponds to that shown in FIGS. 3 and 4.
- the first part 2a is sleeve-shaped and forms (through an inner bore) an inner guide 2j for the shaft 2i of the second part 2b, which is T-shaped or mushroom-shaped.
- the first part 2a further has a stop 2c, through which (through cooperation with the stop l b, see Fig. 6) the tumbler 2 is held in its bore and too far intrusion of the tumbler 2 in the keyhole l a is prevented.

- the tumbler 2 of FIG. 17 is similar to that of FIG. 16. But in this case, the guiding of the second part 2b in the bore is better, but this entails a more complicated production of the second part 2b.
- an inner guide is formed by the second part 2b, while a shaft guided therein is formed by the first part 2a.
- the stopper 2c is formed by the first lo part 2a as in Figs. However, this brings a small wall thickness of the sleeve-shaped second part 2b with it.
- the wall thickness of the sleeve-shaped second part 2b can be greater, so that the second part 2b can be quite robust. However, this can simplify optical readability of the encoding.
- bronze may be chosen for the first part 2a and brass for the second part 2b.
- Typical dimensions are maximum diameter of the tumblers: between 2 mm and 3 mm, and stem or guide diameter between 1 mm 20 and 1.6 mm, with a (diameter-related) oversize for the press fit of between 0.015 mm and 0.04 mm.

- the lock cylinder 1 in addition to the two-part tumblers 2 and two-part Jacobyen 30, which is particularly well seen in Figures 28 and 29.
- the programmable guard-tumbler pairs (in FIG. 20 all ten pairs shown are shown as programmable pairs, but combinations with conventional tumbler-tumbler pairs are also conceivable) are constructed as follows: the first part 2a of the tumbler has the inner end 2e, which projects into the keyway la. It has on the outside a sleeve-like, an opening to the outside opening forming portion which a guide 2j for the second part 2b forms.
- the second part is formed as an inner part, which is feasible inside the sleeve-like portion and which is introduced in the initial configuration only with its inner end in the guide 2j. Because the first part and the second part are matched in their dimensioning so that a press fit results, the second part 2b is fixed relative to the first part 2a.
- the counter-tumblers 30 also have a third, outer part 30a and a fourth, inner part 30b.
- the fourth part 30b is guided in the first part 30a, which is designed sleeve-shaped for this purpose, with a through opening.
- the dimensioning of this through opening is matched to the outer dimensions of the fourth part, that also results in an interference fit between these parts.
- the through opening of the third part 30a can be flared outwards, so that irrespective of the position of the fourth part 30b, an opening 30d bounded towards the bottom (in the arrangement according to FIG. 28, a circumferential groove) results, into which a helical spring of the above described type can engage, the outside of an inner surface of a housing surrounding the stator of the type also already described above pending.
- the fourth part itself is likewise sleeve-shaped, with an inner opening 30c extending in the direction of the bore axis.
- This embodiment is optional and, in embodiments, serves the purpose of programming a "master key system” (MKS), which will be explained in more detail below.
- MKS master key system
- separation arrangement 40 between the first part 2a and the third part 30a.
- This has a plurality of separation elements 41, 42, 43, between each of which a parting line is formed.
- the thickness of the separation elements corresponds to the difference between two adjacent possible coding depths of coding holes of the key (which is here designed as a flat key / reversible key, if the invention is carried out with a pointed key, the thickness corresponds to the distance between two adjacent possible coding stages of the key pink profile).
- the separation elements can be fixed both relative to the second part 2b and relative to the fourth part 30b, here also by an interference fit, by having a continuous, matched in the inner diameter according to the outer diameter of the first and fourth part opening. Accordingly, after the programming, the separation elements can be calculated according to the tumbler or counter-holding.
- a fixation of the separation elements relative to tumbler or Gegenzulets is not even necessary, by the way; Rather, these may, for example, be arranged loosely relative to guard locking / counter-locking, since their function during programming lies in the definition of the distance between the first and third part and the position of the separation elements relative to tumbler and counter-locking is already defined by the arrangement.
- the separation elements 41, 42, 43 are formed as perforated discs. Alternatively, they may initially form a one-piece element with separating points corresponding to the parting lines. Others too Geometries, for example slotted rings are possible; Also not excluded is a permutation inside-out (ie, the second and fourth part are each sleeve-shaped, and the first and third part and the separation arrangement are performed in these sleeves), in the latter case openings for the mandrels of the tool in (in FIGS 20 et seq.) Housing may not be adapted and, for example, may be designed crescent-shaped.
- Fig. 21 shows the lock cylinder of FIG. 20 after insertion of a key 10.
- the tumbler Jacobzuroisspaare are shifted according to the coding of the key in different mass outward, against the spring force of the springs not shown.
- the lock cylinder is ready to be programmed according to the code of the inserted key 10.
- FIG. 22 shows the programming.
- a tool 9 with mandrels 9a designed analogously to the tool described with reference to the first aspect is positioned relative to the lock cylinder such that the pins 9a protrude into the bore and then pressed against the cylinder until a stop surface 9b abuts against a corresponding abutment surface of the cylinder ( formed by the outer surface of the stator in Fig. 22, or alternatively by a surface of the housing not shown).
- the mandrels 9a act on the fourth part, which is pushed further relative to the bore, unless it is due to a particularly deep Codtechniksbohrung the key (as in Fig. 21 at the position PI) anyway so deep in the hole sitting that the corresponding Dorn 9a did not reach it.
- the fourth part 30b is displaced inwardly relative to the third part by the pressing force, thereby pushing the second part inwards relative to the first part. Due to the At the key 10 or the separation arrangement 40, the first and third parts are prevented from moving inwards.
- the length of the mandrels 9a is matched to the dimension of the fourth part, that when pushing the tool up to the stop for all Zuroiss- Gegenzunnenspaare the parting line between the second and the fourth part - which forms the parting line between tumbler and Gegenzunnen - on the parting line between the rotor and stator is aligned, which can be seen well in Fig. 22. Since there is a parting line between the separation order 40 and the first 2a or the third part 30b or between elements 41, 42. 43 of the separation arrangement at each coding depth of the coding bore, this is both a sufficient and necessary condition for that, if the key 10 is introduced, the rotor 5 can be rotated relative to the stator 6.
- Fig. 22 two tools 9 are drawn, one for each of the illustrated coding rows. It is of course also in the presence of several rows, as is usually the case for flat keys to work with only one tool; the tool is then used sequentially for programming the various rows.
- the housing surrounding the stator eg sleeve, not shown in Figures 20-27
- the housing surrounding the stator has an opening aligned therewith per bore in the stator to which a smaller diameter than the bore but a larger diameter than the respective mandrel of the tool has, so that a stop surface for the coil spring is formed and the mandrel can nevertheless act through this opening on the fourth part 30 b.
- the diameter of the mandrel may be larger than the diameter of the inner opening 30c of the fourth Part 30b, but it is smaller than the diameter of the coil spring and the fourth part 30b.
- Fig. 23 shows the programmed lock cylinder after deduction of the key 10. So that the lock cylinder can be actuated by rotation of the rotor 5, the key 10 or a key identical to it must be inserted so that all joints between the second and fourth elements are positioned accordingly.
- lock cylinders to be operated by a plurality of different keys to provide different access permissions, such as for a main entrance and apartment doors, for a master key, or for more complex different hierarchy levels.
- the tumbler counter-hold pairs must have a plurality of parting lines in order to be able to be actuated by different keys, and / or tumbler / counter-hold pairs must be omitted altogether.
- MKS systems Systems with locking cylinders, which can be opened by several different keys, are here called MKS systems. Two possibilities will now be described with reference to FIGS. 24-27, which - in addition to the trivial solution of simply omitting pairs of tumbler / tumbler pairs - give locking cylinders according to the invention also suitability for MBS systems.
- FIG. 24 shows a lock cylinder, which in the initial configuration corresponds to that of FIG. 20 during programming, in a set-up analogous to FIG. 22.
- the tool 9 is constructed more complexly.
- the spikes 9a it has a plurality of programming pins 90. which are guided coaxially with the tumbler and Gegenzuienssbohrung by the tool and can be passed through the inner opening 30c of the fourth part 30b and through the inner opening of the separation assembly 40 and so can act directly on the second part 2b.
- the tool 9 per mandrel is equipped with a programming pin 90, but this is optional: if it is known from the outset. At which position the tumbler-counter-hold pair should have a plurality of joints, an assembly can only be present at those positions.
- the functions of the mandrels 9a and the programming pins 90 can also be implemented by two different tools which are set successively, or the same tool can be used twice without programming pins and once with programming pins twice in succession.
- the programming pins 90 are adjustable (in the illustrated embodiment relative to the body and the spikes 9a of the tool) that they protrude differently far into the holes and slide the second parts 2b different degrees inward when guiding the tool to the stop 9b. In particular, it can push a second part 2b further inward than it has been pushed by the fourth part 30b by the action of the dome 9a, so that in this case the second part lies at a defined distance from the fourth part. You can see that in Fig. 25, too. which shows the situation after removing the tool 9 and removing the key.
- the distance at the position PI is two units (one unit is the difference between two adjacent possible defined coding depths of encoder holes of the Key, corresponding to the distance between two adjacent joints of the separation assembly 40, here corresponding to the thickness of one of the separation elements 41, 42, 43), three units at position P5, one at position P3, and none at positions P2 and P4 Distance available.
- the separation elements in the space may optionally remain in the bore of the tumbler or the counterstay when the rotor is rotated relative to the stator - similar to a so-called “split pin” as known in conventional mechanical locking systems with MKS function.
- the number of parting lines per tumbler-antagonist pair is a + 1, where a is the distance measured in said units.
- Fig. 26 shows an alternative approach to this, in which individual pairs of tumbler counteracting - in the example shown, the two pairs with respect to the key opening completely inside, ie the leftmost in the illustration of Fig. 26 - not programmable, but as a pair of conventional tumblers 22 and Gegenzunnenen 23, with a split pin 24 in between, are formed.
- the split pin 24 - or at most several split pins per pair of holes - can be formed as known per se in different thicknesses, and so different joints correspondingly defined coding depths of the corresponding bore on the key. Thawing and programming of the other guard locking counter pairs is as described with reference to FIG. 20-23.
- Fig. 27 shows the lock cylinder 1 after programming.
- the conventional MKS-tumbler-counter-hold pairs can optionally be identical for all lock cylinders of a series of lock cylinders and thus also be deliverable as generic cylinders, but their design provides a MKS function.
- a first alternative to interference fit is, for example, a latching system, according to which the second part relative to the first part and / or optionally the fourth part can engage relative to the third part at a plurality of defined positions.
- the second part may have a small circumferential rib or at least one latching projection which can engage in one of a plurality of corresponding grooves or latching openings of the first part; The same applies analogously to the fourth part and the third part.
- a second alternative to press-fitting is to glue, then a small amount of adhesive is introduced between the first and second part and / or between the third and fourth part before programming, and the tool is removed only after the adhesive has cured.
