Definitions
- the invention relates to a lock cylinder, in particular a programmable lock cylinder, and a method for programming a lock cylinder.
- Lock cylinders have a stator (sometimes also called “cylinder housing”) that can be non-rotatably attached to a lock and a rotor (sometimes called “cylinder core”) that can be rotated around the axis of the lock cylinder when a suitable key is inserted. As a result of the rotation of the rotor, output means are moved which are used to actuate a bolt or other means associated with the desired function of the locking cylinder.
- stator sometimes also called “cylinder housing”
- a rotor sometimes called “cylinder core”
- the rotor is a cylinder inserted into the stator with a plurality of bores which extend through the rotor and the stator and into each of which a tumbler, a counter-tumbler and a helical spring are inserted. Guard locking and counter locking can be moved along the axis of the bore and a restoring force is applied by the helical spring.
- Lock cylinders are typically manufactured individually, so that each of the tumblers has a length that is matched to an associated key. The lengths correspond to the coding introduced in the key, which is manifested in depressions of different depths in a defined position (and scanned by the respective tumbler) on the key. This means that a great deal of effort must be made for both production and distribution.
- a locking cylinder can be programmed, i.e. individualized, retrospectively after assembly.
- a generic, ie not yet customizable, still programmable locking cylinder can be manufactured, which enables more efficient and more automated production.
- generic locking cylinders can be supplied, which are only programmed afterwards, for example at the place of use or at a dealer.
- WO 2010/103032 A1 it is proposed in WO 2010/103032 A1 to provide tumblers, the length of which is adjustable by turning a part of the tumbler provided with an internal thread relative to a part of the tumbler provided with a matching external thread.
- Other programmable locking cylinders are e.g. from EP 2 152 986, WO 2007/05051 1 A2 and US 2003/0084692 A1.
- No. 3,190,093 shows a locking system for serrated keys in which the locking cylinder is initially programmed to a temporary key and can be reprogrammed to a secondary key with a less deep notch at the location of a special tumbler-counter tumbler pair.
- a programmable locking cylinder is known from WO 2016/141496 which, compared to the prior art, enables simple, precise, rapid and secure programming, which also enables a great number of different permutations and great flexibility. This is done by a tumbler and counter tumbler are each composed of two parts that are each connected to one another in a press fit. The total effective closing length of the guard locking and the counter locking can be changed by moving the two guard locking parts or the two counter locking parts against each other.
- the programming - i.e. changing the total length of guard locking and counter locking depending on the required coding - is carried out by a tool which moves part of the counter locking and part of the guard relative to each other, whereby the closing length of the guard locking and the closing length of the Change counter-locking.
- the disadvantage is that a relatively large number of relatively small components have to be assembled in the production of the programmable cylinder with separation arrangement, especially since the separation arrangement itself generally also consists of several elements, and tumbler and counter-tumbler are also made up of four parts It is an object of the present invention to provide a mechanically programmable lock cylinder which overcomes the disadvantages of the prior art.
- the locking cylinder should be as simple as possible to manufacture and program without having to compromise on security.
- a mechanically programmable lock cylinder which has a stator and a rotor with a key channel that can rotate in the stator and into which a key can be inserted.
- the rotor and stator have a plurality of bores extending transversely to the keyway (i.e. radially with respect to an axis of the lock cylinder) and in a basic state in pairs aligned with one another for receiving tumbler-counter tumbler pairs.
- Such bores are known per se for mechanical lock cylinders.
- the bores run “radially” does not have to mean that their axis runs exactly through the cylinder axis and is perpendicular to it, although that is a possibility. Rather, the bores can also meet, for example, perpendicularly on a flat side / the key channel but be slightly offset from the central axis, and / or it is also possible that they hit the key channel at an angle.
- “radial” generally denotes directions to the key channel towards or away from this, in contrast to directions that are “axial” in relation to the lock cylinder, which run parallel to the keyway and the axis of rotation of the rotor.
- a tumbler element which defines at least one base body of a tumbler axis which coincides with an axis of the bores, and a programming part arrangement having.
- the base body has a radially inner end section which protrudes into the key channel in order to scan a coding of the key, as is known per se from tumblers.
- the base body also has a plurality of predetermined breaking points.
- the programming part arrangement is held by the base body and has at least one separating joint. The programming part arrangement is displaceable along the tumbler axis relative to the base body, so that the parting line can optionally be aligned with one of the predetermined breaking points.
- a mechanical programming of the lock cylinder can then take place in such a way that, with the programming key inserted, the programming part arrangement can first be brought into a position in which the mentioned separating line is aligned with the shear surface between rotor and stator. This can be done using a generic tool that does not need to have any information about the programming to be carried out. Then, by rotating the rotor, the base body can be separated along the predetermined breaking point at which the separating joint is aligned. The separating joint then, together with the separating point between the resulting fragments of the base body, forms a separating surface of the tumbler-counter-tumbler pair obtained through the programming.
- the programming part arrangement consists of a first and a second programming part, which are separated from one another by the separating joint.
- the programming parts can be separate, or possibly also be separated from one another at the point of the parting line by a further predetermined breaking point.
- the radially inner fragment of the base body together with the radially inner programming part forms the tumbler
- the radially outer fragment of the base body with the radially outer programming part forms the counter hold.
- the guard locking / counter locking pairs then each have two parts and correspond to those in WO 2016/141496 described, composed of a total of four parts tumbler-counter tumbler pairs and consequently also have their advantages. Due to the procedure according to the invention, however, there is no need for a separation arrangement. The approach according to the invention presented here is therefore much simpler, in particular also in terms of assembly.
- the programming part arrangement has a plurality of the parting lines. This can mean in particular that, in addition to a radially inner first programming part and a radially outer second programming part, at least one third programming part arranged between these is present.
- the joints between the first and third programming part on the one hand and between the third and second programming part on the other hand can be aligned one after the other to the shear surface between rotor and stator by different programming keys and thus a guard locking system with several separating surfaces is created at the corresponding position, creating a so-called "master Key System “(MKS) can be generated in which a cylinder can be unlocked with various matching keys.
- MKS master Key System
- tumbler elements with just one separating joint are generally also present - at correspondingly different positions in the cylinder - for generating conventional tumbler-counter-locking pairs, i.e.
- tumbler elements with several parting lines are generally only present in one or a few positions in the lock cylinder.
- the parting lines of the programming part arrangement will generally form a plane which can be aligned with the shear surface between rotor and stator, ie they are in Tangential reference to the cylinder axis. In the case of radial bores, this means that the corresponding parting line runs perpendicular to a guard locking axis.
- the predetermined breaking points are designed in such a way that they also enable the base body to be separated along a plane that is tangential with respect to the cylinder axis. They can in particular be formed by grooves running around the outside of the base body (in a plane tangential with respect to the cylinder axis) and / or, if the base body is locally hollow-cylindrical, grooves running around on the inside.
- the programming parts of the programming part arrangement can, for example, each have the shape of a cylindrical ring - in particular with a bevel or beveled end face - and surround a part (coding part) provided with the predetermined breaking points.
- This part can in turn be hollow-cylindrical, in particular so that it has sufficient elasticity, and the formation of the predetermined breaking points as circumferential grooves is then particularly favorable.
- the coding section can be wood-cylindrical with an inner diameter corresponding to the circumstances, and the programming element arrangement can then be arranged inside the hollow cylinder and, for example, be designed as an arrangement of cylindrical blocks.
- the predetermined breaking points can also be formed in this embodiment by circumferential grooves. In both variants, circumferential grooves are conceivable on the outside (particularly easy to manufacture) and / or on the inside of the hollow cylinder.
- the configuration with programming parts which surround the part provided with the predetermined breaking points (coding part), however, has the advantage that after programming has been carried out, the predetermined breaking points through the respective cylindrical ring protected and protected against unwanted, for example subsequent breaking.
- the torque is very high, a break can occur.
- the total length of the tumbler element is constant when the separating element arrangement is displaced and does not depend on which of the predetermined breaking points the separating joint is aligned with.
- each individual programming element - is / are in embodiments connected to the base body with a press fit.
- An interference fit is sometimes referred to as an interference fit. Due to the press fit, the two parts are so firmly connected that they maintain their relative position even after years of use and after other typically occurring mechanical loads.
- the locking cylinder for each tumbler-counter-tumbler pair can have a spring, in particular a helical spring, which presses it radially inward.
- a spring in particular also act on the base body of each of the tumbler elements and, for example, be connected to it.
- the present invention also relates to a method for programming the lock cylinder.
- This programming is carried out as intended by a Key with a code to which the lock cylinder is to be programmed is inserted.
- the tumbler elements are then set up according to the coding by aligning the parting line (for tumbler elements with several parting lines: one of them) to the shear surface between the rotor and stator. This can be done with knowledge of the dimensioning of the programming part arrangement (this will be the same for all tumbler elements or at least in groups, for example) without the programming tool or the person programming having information about the coding, in particular with that described in WO 2016/141496 Action.
- the rotor in the stator is rotated in order to separate the base body at that predetermined breaking point which is aligned with the parting line and the shear surface.
- a key with the same coding can unlock the lock cylinder at any time.
- FIG. 1 shows a programmable lock cylinder in section
- FIG. 2 shows a tumbler element for the lock cylinder according to FIG. 1
- Fig. 6 shows the lock cylinder of Fig. 1 with the key inserted in front of the
- FIGS. 1 and 6 shows the lock cylinder of FIGS. 1 and 6 with the key inserted following the programming
- FIGS. 1, 6 and 7 shows the lock cylinder of FIGS. 1, 6 and 7 without a key following the programming; and 9 shows a variant of a tumbler element with a larger number of
- Fig. 1 shows a lock cylinder 1 with a rotor 5 and a stator 6 as well as a sleeve 7.
- the rotor forms a key channel 8. In the example shown, this is for inserting a flat key from the axially outside, i.e. in fig. 1 from the left, trained.
- the rotor has an output structure 9 which, after the lock cylinder has been installed as intended, interacts with or forms output means.
- the housing can include, in addition to the sleeve, further parts, for example, at least partially surrounding the sleeve, which is not shown in FIG. 1.
- the rotor and stator have radial bores 51 and 61 for tumbler-counter tumbler pairs. These bores of the rotor and stator are aligned with one another in a basic state shown in the figures and form a common tumbler bore.
- the present locking cylinder differs from locking cylinders of the known type in that it does not come with finished tumbler-counter-tumbler pairs is equipped, but with tumbler elements 2, one of which is shown enlarged in FIG.
- the tumbler element 2 has a base body 21, also shown in FIG. 3, which forms, radially inwardly (to the left in FIG. 2), an end section 22 which tapers to a point, for example, for scanning a key code.
- the base body has a flange-like widening 23 which, together with a shoulder of the radial bore in the rotor 5, forms a stop against which the base body is pressed by a spring 4 when no key is inserted.
- the tumbler element also has a coding section 24 on the radially outer side. In the illustrated embodiment, the coding part is sleeve-shaped.
- the spring 4 is firmly connected to the base body by an end piece of the spring being pressed into the hollow-cylindrical coding part 24 on the inside.
- the coding part holds an inner programming part 31 and an outer programming part 32.
- the inner and outer programming part can be displaced along the tumbler axis (that is, radially with respect to the lock cylinder) relative to the base body 21, the programming parts 31, 32 being mounted on the base body in such a way that they are not easy to move, but can only be moved with considerable effort.
- the programming parts 31, 32 which are also shown in FIG. 4 and FIG. 5, are designed as essentially cylindrical rings and pushed onto the coding section 24 of the base body 21.
- the programming parts 31, 32 are each provided with a bevel 38 on the outside with respect to their axis, the bevel being relatively pronounced towards the common parting line 39 (or can also be replaced by an end surface that slopes downwards overall) so that the lock cylinder does not jam, if the alignment of the parting surface formed by the parting line and break point is not perfectly aligned with the shear surface between rotor and stator.
- the radially further outwardly arranged second programming part 32 protrudes only insignificantly beyond the end surface of the base body 21, which is why the total length of the tumbler element 2 does not (at least not significantly) depend on the position of the programming parts relative to the base body. After programming, the sum of the lengths of guard locking and counter locking is always the same.
- a plurality of predetermined breaking points in the form of circumferential grooves 25 are formed on the coding part 24 of the base body.
- a shear force between the programming parts 31, 32 can cut the coding part 24 at these points, and the tumbler element is then composed of four parts: The radially inner fragment of the base body with the first programming part 31 held by it forms the tumbler, and the The radially outer fragment of the base body with the second programming part 32 forms the counter-locking device, a separating surface being created from the separating line 39 and the break point.
- FIG. 6 shows the lock cylinder from FIG. 1 with the key inserted, on which the lock cylinder is to be programmed.
- the tumbler elements 2 are shifted or not to a greater or lesser extent radially outwards against the force of the springs — which are not visible in FIGS. 6 and 7 for reasons of illustration.
- the intended depths the coding holes - with flat keys for example, three, four or five coding levels per hole can be provided, in the example shown three levels are assumed - are matched to the dimensions of the base body so that when the key is inserted, one of the predetermined breaking points with the shear surface between rotor 5 and stator 6 is aligned.
- the shear surface is aligned at positions 1, 3, 9 and 11 with the radially outermost predetermined breaking point, at position 5 with the middle predetermined breaking point and at position 7 with the radially innermost predetermined breaking point.
- the programming parts 31, 32 are then shifted radially inward relative to the base body, depending on the position, for example with the method as is known from WO 2016/141496.
- a tool can be used which has a long extension (dome) per radial bore 51, 61 in a row, which through an opening in the housing (here: the sleeve) with the second Programming part is brought into contact, whereupon the tool is pressed against a stop, whereby the second programming part 32 and the first programming part 31 are shifted radially inward so far that the interface between them is aligned with the shear surface between rotor and stator.
- this process can be carried out in parallel for several of the tumbler elements, for example for a whole row in each case, or it can also be carried out individually, coding element by coding element.
- a generic tool can be used which does not contain any information about the programming to be carried out. This is because the distance between the radially outer end face of the second programming part 32 and the said shear face is only determined by the - generic - extension of the second programming part along the axis of the tumbler bores.
- the programming parts are attached to the outside of the coding section, while the spring 4, which is the tumbler element or after programming the tumbler-counter tumbler pair pushes radially inwards and engages the inside of the base body.
- the opening through which the tool engages can be eccentric with respect to the radial bore.
- the tool can then have a corresponding pair of extensions.
- Other configurations which enable the tool to engage in order to move the programming parts and at the same time to support the spring are readily conceivable.
- FIG. 7 shows the lock cylinder with the key still inserted after this process and after the programming has been completed by cutting the base body at the location of the corresponding predetermined breaking point by rotating the rotor in the stator.
- the rotation of the rotor which, depending on the strength of the base body, can be associated with a certain substantial torque, can be carried out, for example, by a tool that acts on the output structure 9.
- Programming by turning the key is also possible, provided that a sufficiently high torque can be applied to the key.
- the radially inner fragment of the base body 5 forms a tumbler with the first programming part 31 held by it, and the radially outer fragment of the base body with the second programming part 32 forms a counter tumbler.
- Figure 8 shows the cylinder programmed accordingly.
- the mode of operation of the locking cylinder with its tumblers and counter-tumblers created by programming from the tumbler element corresponds to the programming of a conventional locking cylinder equipped according to the desired coding.
- the lock cylinder can be brought back into the state of FIG. 7, in which a rotation of the rotor in the stator is possible because all separating surfaces between tumbler and counter tumbler are aligned with the shear surface between rotor and stator.
- a special feature of the construction described is that the programmed guard locking-counter locking pairs all have the same overall length. This total length corresponds to the original length of the base body. The sum of the lengths of the guard locking and counter locking does not depend on the programming. This is an advantageous, depending on the application, even important security feature.
- tumbler-counter-tumbler pairs obtained by mechanical programming as described by conventional tumbler-counter-tumbler pairs by only fitting some of the radial bores with tumbler elements.
- This can also be used, for example, for an MKS, i.e. to produce a lock cylinder that can be unlocked with several differently coded keys.
- MKS i.e. to produce a lock cylinder that can be unlocked with several differently coded keys.
- WO 2016/141496 deals with the combinations between mechanically programmable guard locking / counter locking pairs and other guard locking / counter locking pairs.
- FIG. 9 shows a tumbler element for forming a tumbler-counter tumbler pair with a “split pin”.
- a third programming part 33 is arranged between the first programming part 31 and the second programming part 32.
- a second programming key is then inserted. This has a at the position of the tumbler to be provided with a split pin
- Coding hole the depth of which differs by the thickness of the third programming part from the depth of the corresponding coding hole of the first programming key.
- the rotor is then rotated again in the stator in order to cut through the base body at the location of a further predetermined breaking point 25. This then results in three fragments of the main body.
- One of them carries a radial inner one
- a middle fragment carries the third programming part and together with this forms the split pin.
- a radially outer fragment carries the second programming part and together with it forms the counter locking. The total length of these three elements tumbler-split pin-counter tumbler is again not dependent on the programming and corresponds to the original length of the base body 21.
- This procedure can also be used for more than one split pin, in which case the number of programming parts must be increased accordingly.
- the length of the base body 21 of the embodiment of FIG. 9 is greater than that of FIG. In a system with both guard locking / counter locking pairs with split pins and with guard locking / counter locking pairs without such, the lengths of these two can be the same or different. It can be provided that the number of programming elements is identical for all pairs, ie at all positions, and that the pairs with or without split pin only differ in that the former has been severed at the location of a second predetermined breaking point and the second not. For safety reasons, however, it can also be provided that this is not the case at the moment, and that the programming elements prevent a second severing through their dimensioning (axial length) at the positions where there should be no split pin.
- the principle of the programmable lock cylinder has been described above using the example “flat key”, in particular “reversible key”. But that is not a necessity.
- the principle can also be used analogously, for example, for pointed keys. These generally only have a single series of interlocking-interlocking pairs. In return, they allow a larger number of coding levels per position, which is why the base body and the programming element for such an embodiment will generally be longer than in the examples described above, and the base body will have a larger number of predetermined breaking points.
- the coding part of the base body can be sleeve-shaped with a comparatively somewhat larger inner diameter
- the programming elements can be arranged inside this coding part, for example as essentially cylindrical blocks.
- the predetermined breaking points are then, for example, through circumferential grooves formed on the inside and / or outside of the cylinder of the coding section.
- a first alternative to a press fit is, for example, a latching system, according to which the programming parts can latch into a plurality of defined positions relative to the base body.
- a second alternative to press fit is gluing, in which case a small amount of adhesive is then introduced between the base body and the programming parts before programming, and the tool is only removed, for example, after the adhesive has at least partially cured.
