Definitions

  • the present invention relates to a locking device having a base body, which has a core receptacle, with a cylinder core which is rotatably received about an axis of rotation in the core receptacle of the main body and has a key channel for a closure device associated key, and with a plurality of tumblers, partially in The keyway protrude and are designed to lock the cylinder core in a normal position of the cylinder core against rotation out of the normal position, unless they are arranged, in particular by the associated key, in a cylinder core releasing configuration.
  • Such a closing device can in particular be designed as a lock cylinder, for instance for use in doors, wherein it may then be a cylinder housing for the cylinder core in the base body.
  • the main body can also be formed, for example, by the lock body of a lock, for example a mobile lock such as a padlock.
  • the locking device can in principle be designed in any other way, but in each case according to the same principle, a rotation of the cylinder core only by means of the correct key is possible and otherwise locked by the tumblers.
  • the cylinder core does not necessarily have an exact cylindrical shape.
  • it is at least substantially cylindrical, with the core receptacle provided for it in the main body having a corresponding shape, so that the cylinder core can be reliably rotated in the core receptacle. is gert.
  • the axis of rotation of the rotatability can then correspond in particular at the same time to a cylinder axis and / or an axis of symmetry of the cylinder core or the core receptacle.
  • the keyway advantageously extends parallel to the axis of rotation, and in particular the axis of rotation passes through the keyway, so that the associated key, when inserted into the keyway, can be rotated together with the cylinder core about its own axis.
  • Said normal position of the cylinder core of the closing device is a rotational position in which the cylinder core can be locked by the tumblers against rotation, namely in particular if not the associated key inserted in the keyway.
  • the cylinder core starting from said normal position after a full rotation about the axis of rotation again occupy such a rotational position, but this rotational position is not considered as a further normal position, but as the same normal position. Since one locking state of the locking device can change as a result of one or more full revolutions of the cylinder core, the normal position is therefore not set to a specific locking state.
  • the respective object on which the locking device is provided e.g.
  • the cylinder core is basically rotatable relative to the main body. However, in the normal position this rotation can be prevented by the tumblers initially.
  • the tumblers can be used, for or be designed as platelet tumblers and are expediently biased into a position in which they extend over the interface between the base body and the cylinder core such that they thereby lock the cylinder core against rotation relative to the base body.
  • each of the plurality of tumblers is moved to just that position in which it no longer locks the cylinder core with respect to the main body, this position being different for different tumblers.
  • the enabling configuration i. to know which tumbler must be positioned and how.
  • This information is coded in the key associated with the locking device insofar as the key, in particular a profile provided on a key shank of the key, optionally forces the tumblers into their respective releasing position counter to a bias when the key is correctly inserted in the keyway of the cylinder core ,
  • the safety of the respective closing device therefore depends, among other things, on how easily the tumblers are held in a manner other than by the key associated with the closing device - e.g. by so-called setting the tumblers by means of lock picking tools or by means of a simulated
  • a locking device of the type mentioned a key for such a locking device, a locking system comprising such a locking device and such a key, or to provide a key blank for making such a key which provides improved protection against irregular unlocking while allowing for easy and comfortable operation.
  • the object is achieved by a locking device having the features of claim 1, by a key having the features of claim 14, by a locking system having the features of claim 18 and by a key blank having the features of claim 19.
  • the cylinder core has a movably mounted locking element which is radially outwardly biased relative to the axis of rotation and which is designed to be held in a neutral position by the associated key against this pretensioning.
  • the blocking element and the cylinder core on which it is mounted may be connected to each other for common rotation about the rotation axis, so that the blocking element can not be rotated without the blocking element without the cylinder core and the cylinder core.
  • the cylinder core can be locked against rotation by the movement path which passes through the locking element upon rotation of the cylinder core is blocked. Since the blocking element is movably mounted on the cylinder core, the respectively traversed trajectory depends on the respective position of the blocking element, so that the rotation of the cylinder core can be blocked in dependence on the position of the blocking element.
  • the blocking element is biased radially outwardly, ie in a position in which it extends as far as possible within its mobility currently possible radially away from the axis of rotation away.
  • the blocking element is preferably mounted at least substantially linearly displaceable on the cylinder core, wherein the direction of the mobility is aligned in particular at least substantially radially to the axis of rotation, ie the axis of rotation intersects.
  • the blocking element can also be oriented differently from it and / or be movably mounted on the cylinder core, for example pivotally or rotatably, wherein the blocking element is then biased radially outwards insofar as it is biased in the direction of a position a point of the blocking element which is farthest from the axis of rotation is as far as possible from the axis of rotation. Contrary to this bias, the blocking element can be kept in a neutral position.
  • the blocking element In the neutral position, the blocking element thus extends radially with respect to the axis of rotation not so far outward as in positions in which the blocking element is biased contrast and therefore occupies it, if it is not held in the neutral position, ie in particular when the cylinder core is operated without a key or with a wrong key.
  • the blocking element In the neutral position, the blocking element may in particular be arranged such that it does not protrude beyond the cylinder core in the radial direction, but in particular terminates flush with a lateral surface of the cylinder core. If it is not held in this neutral position, the blocking element is then displaced as a result of the bias in a position in which it projects beyond the cylinder core.
  • the neutral position need not necessarily designate a single radial position of the blocking element, but may also include all those positions of the blocking element in which the blocking element radially outward no further than up to a certain edge position, for example, that position in which it flush closes with a lateral surface of the cylinder core is arranged.
  • the blocking element is specially designed, in particular by the associated key, to be held in this neutral position.
  • the interaction kung between the bowl and the blocking element, by which the holding is achieved can in principle be done in various ways, for example mechanically or preferably magnetically (as will be explained below).
  • the interaction is such that as far as possible or only with possible lent great effort in other ways than with the associated key holding the locking element in the neutral position against the bias can be achieved and that copying of the key with respect to this function also possible not or only with the greatest possible effort to accomplish is.
  • additional locking against irregular rotation of the cylinder core can be realized by the blocking element in addition to the blocking of the cylinder core by the tumblers, whereby the safety of the locking device is improved. Since the same bowl can be used for arranging the tumblers in the releasing configuration as for holding the blocking element in the neutral position, advantageously no additional effort is required for a user of the closing device in spite of the additional securing in the operation of the locking device.
  • the additional locking of the cylinder core by said blocking element takes place in cooperation of the blocking element with a formed on an inner circumferential surface of the core receiving stop portion and depending on whether the locking element is held in the neutral position or due to the bias beyond the neutral position also radially is offset externally.
  • the inner lateral surface of the core receptacle can be formed, in particular, by a, preferably cylinder-jacket-shaped, inner wall of the core receptacle, against which the cylinder core rests with an outer circumferential surface or slides along during rotation.
  • the abutment portion can be formed, for example, by a step in said lateral surface at which the radius of the lateral surface changes abruptly.
  • the lateral surface may, for example, have a depression which is limited in the circumferential direction on at least one side by such a step.
  • the limit position can be assumed starting from the normal position, for example by a rotation of the cylinder core about the rotation axis by at least about 5 °, preferably by at least about 10 °, in particular by at least about 20 °.
  • the cylinder core is freely rotatable in the releasing configuration of the tumblers. In other words, it is a prerequisite for rotation of the cylinder core from the normal position that the tumblers are arranged in the releasing configuration; but if this is the case, the cylinder core can be rotated in at least one direction of rotation to the limit position and regardless of whether the locking element is held in the neutral position or not.
  • the blocking element In the limit position, however, it depends on the position of the blocking element, whether the blocking element can be moved past the stop section and thus the cylinder core can be rotated beyond the limit position or whether the blocking element abuts against the stop section and thereby causes the cylinder core to rotate is prevented beyond the limit position. Only when the blocking element is in the neutral position despite the bias, it can be guided past the stopper portion. Otherwise, so if it extends beyond the neutral position radially outward, the blocking element abuts against the stopper portion. Thus, even if one should succeed in arranging the tumblers in the releasing configuration, the cylinder core is at least secured against turning beyond said limit position.
  • the cylinder core is not locked by the blocking element but not in the starting position, namely the normal position, but is freely rotatable up to the limit position.
  • the blocking element is adapted to be held by the associated key by magnetic attraction in the neutral position.
  • the blocking element or at least a part thereof may comprise a soft magnetic material that can be attracted by a provided in the key at a suitable location, in particular on a key shank of the key, permanent magnet. Due to this magnetic interaction, the blocking element can then be held in the neutral position as long as the key is inserted in the key channel. Otherwise, however, the blocking element is not held in the neutral position, so that it can not be passed in the limit position on the stopper portion.
  • a magnetic attraction acting on the blocking element and defined with respect to the location and the direction is a prerequisite for being able to turn the cylinder core beyond the limiting position.
  • Such magnetic attraction of the locking element can not be easily adjusted by means of lock picking tools.
  • key blanks used to copy keys typically do not have magnetic elements to create a defined magnetic attraction.
  • even copied keys can be provided with permanent magnets. However, this increases the cost of producing the copy considerably. Therefore, by this embodiment, the safety of the locking device according to the invention against irregular operation can be further increased.
  • a holding portion is formed on the inner Mantelflä- surface of the core receptacle, which holds the locking element in the normal position of the cylinder core against the biasing force acting on the locking element in the neutral position.
  • the blocking element is thus not only in the neutral position when the key of the locking device is inserted key is inserted into the keyway and holds the locking element, in particular by magnetic attraction, in the neutral position, but regardless of the key also then, when the cylinder core is in the normal position, in which it is then held by the said holding portion of the core holder in the neutral position.
  • the blocking element is further arranged so that it is at least substantially immediately adjacent to the inserted in the keyway key in the neutral position, so that there provided a permanent magnet only has to have a relatively short range in order to reliably cooperate magnetically with the blocking element.
  • a transition section is formed on the inner circumferential surface of the core receptacle between the stopper portion and the holding portion along which increases the radius of the core receptacle with respect to the axis of rotation from the holding portion to a adjacent to the abutment portion recessed portion.
  • the radial height profile of the transition section in the circumferential direction defines the radial position of the locking element in dependence on the respective rotational position of the cylinder core on its way from the normal position in the Limit position or vice versa from the limit position to the normal position.
  • the blocking element In the normal position, the blocking element is held by the holding portion in the neutral position, whereas the blocking element in the limit position abuts against the abutment portion adjacent recess portion having a larger radius compared to the holding portion, so that the blocking element in the limit position of the cylinder core on the neutral position protrudes radially outward.
  • the radius of the core receptacle changes, ie the radial height profile of the transition section, preferably continuously, thus has no abrupt transitions, so that the blocking element along the entire course of the transition section can be passed unhindered.
  • the radius increases from the holding section to the recess section in a monotone, although not necessarily strictly monotone, although this increase does not necessarily have to be uniform, but, for example, a curved course is also possible.
  • Such a transition section can act as a kind of ramp by which the blocking element is automatically urged against its bias in its neutral position when the cylinder core is rotated from the limit position to the normal position.
  • a further abutment portion is formed on the inner circumferential surface of the core receptacle, which is arranged in the opposite direction from the normal position of the cylinder core in comparison to said abutment portion and by which a further different from the normal position limit position of the cylinder core is defined up to which the cylinder core in the releasing configuration of the tumblers, starting from the normal position in the opposite direction of rotation is freely rotatable and in which the blocking element, if it is not in the neutral position, but in particular projects radially outward on the neutral position, at the other Stop section abuts to lock rotation of the cylinder core in the opposite direction beyond the further limit position addition.
  • the named point with respect to which the inner circumferential surface of the core receptacle is designed to be rotationally symmetrical in particular, it may correspond to the midpoint of the mentioned holding section in the circumferential direction.
  • the closing device comprises a guide element which is inserted into a recess of the base body provided on the inner lateral surface of the core receptacle and has the stopper section. If a further stop section, a holding section and / or a transition section are also provided, the guide element preferably also has one or more of these elements.
  • the stopper portion is formed in this embodiment, not directly in the body, but in a separate guide member, which is, however, attached to the body.
  • Such an embodiment has the advantage, for example, that the guide element, which cooperates with the blocking element, can be formed from a different material than the base body, in particular a material which may be suitable especially for the function of the guide element. Furthermore, by introducing a corresponding recess and inserting the guide element into the recess, the basic body of a conventional closing device can thus be retrofitted in accordance with the invention.
  • the said recess in a direction tangential to the axis of rotation has a continuous uniform cross section, ie that the cross section is at least substantially constant in the said tangential direction.
  • the recess may extend tangentially to the axis of rotation from outside the main body into the main body, so that the guide element, which advantageously has a corresponding cross section, can long this extension can be used in the recess.
  • the recess then extends from an outside of the main body at least to the inner lateral surface of the core receptacle or along it, so that the inserted guide element can interact with the blocking element of the cylinder core inserted into the core receptacle.
  • the recess extends completely through the base body, so that the guide element can be selectively inserted into the recess at one of two opposite ends of the recess from outside the base body.
  • the provision of a tangential recess with consistently uniform cross-section has not only advantages in assembling the locking device, but also in the manufacture of the body, since the recess can be introduced in this way by a broaching operation from outside the body in the body.

In this position, the blocking element 33 abuts in the circumferential direction against a stop section 51 formed on the inner circumferential surface of the core receptacle 15 when the cylinder core 17 is rotated out of the normal position (compare FIG. 1 b). In this respect, the stopper section 51 defines the limit position of the cylinder core 17 shown in FIG.
  • the blocking element 33 When the blocking element 33 abuts against the abutment portion 51, the radially outer shoulder 37, 39 'formed by the increase in diameter 37 lies straight against the inner circumferential surface of the core receptacle 15. As a result, the blocking element 33 is supported particularly reliably on the abutment portion 51, so that the blocking of the cylinder core 17 beyond the limit position can not be overcome.
  • stop portion 51 ' On the inner circumferential surface of the Kernaufnahnne 15 is another stop portion 51 'is formed, which defines in a similar manner as said stopper portion 51 a further limit position of the cylinder core 17, beyond which the cylinder core, starting from the Nornnal too in a second, the first rotational direction opposite Direction of rotation (in the example shown in the counterclockwise direction) can not be rotated as long as the locking element 33 is not held in its neutral position and thereby can be passed to the stop portion 51 '.
  • the stopper portions 51, 51 ' are at least substantially symmetrical to each other.
  • the provided on the key shank 29 of the associated key 27 permanent magnets 49 may be sufficiently strong to pull the locking element 33 from a relative to the neutral position radially outwardly offset position in the neutral position.
  • this is advantageously not necessary because the blocking element in the normal position shown in Fig. 1 a of the cylinder core 17, in which the key 27 can be inserted into the key shank 29, anyway by a formed on the inner circumferential surface of the core holder 15 holding portion 53 in the neutral position is held.
  • the two abutment portions 51, 51 ' are arranged equidistant from the holding portion 53 in the circumferential direction, so that the two limit positions relative to the normal position of the cylinder core 17 have the same angle of rotation, albeit in the opposite direction of rotation.
  • abutment portion 51 and the holding portion 53 each have a transition portion 55, 55' along which the radius of the core receptacle 15 with respect to the axis of rotation R starting from the holding portion 53 to a the respective stop portion 55, 55 'adjacent respective recess portion 57, 57' increases.
  • the transition section 55, 55 acts insofar as a ramp on which the blocking element 33 slides along with its radially outer end side due to the bias, so that the locking element 33 is forced back into its neutral position upon rotation of the cylinder core 17 from one of the two limit positions into the normal position.
  • a rotation of the cylinder core 17 is thus not blocked from a limit position to the normal position, as would be the case if between the respective recess portion 57, 57 'and the holding portion 53, a step would be formed.
  • the holding section 53, the transition sections 55, 55 ', the recessed sections 57, 57' and the abutment sections 51, 51 ' are each not formed directly in the main body 13, but in a separate guide element 59, which is in one on the inner Cloak surface of the core receptacle 15 provided recess 61 of the base body 13 is inserted.
  • the recess 61 has been introduced into the main body 13 as pocket milling.
  • FIGS. 4a, 4b, 5 and 6 show an alternative embodiment in which the recess 61 'has been introduced into the main body 13 by a broaching operation from outside the main body 13.
  • the recess 61 'in this embodiment has a continuous uniform cross-section, because the recess 61' can be thought of as a geometric body with respect to a longitudinal axis constant cross-section, with the axis of rotation R tangential arrangement the longitudinal axis of the main body 13 is subtracted.
  • the guide element 59 ' which advantageously has a corresponding cross section (cf., FIG. 6), can simply be pushed into the recess 61' from outside the main body 13, instead of from the core seat 15.
  • the recess 61 ' may, for example, have the cross-section shown in FIG. 5, which has at least substantially the shape of an isosceles trapezium.
  • a rectangle connects to the shorter base side of the trapezoid, so that the recess 61 'is open to the outside of the main body 13 throughout.
  • the recess 61 ' can also be closed like a channel, so that it is open to the outside of the main body 13 only at two ends or only at one end of its longitudinal extent.
  • the recess 61 ' is in any case open in such a way that the guide element 59' can be placed in the recess 61 'such that at least the stop section 51 and possibly also the further stop section 51', the holding section 53, the transition sections 55 , 55 'and / or the recessed portions 57, 57' are arranged on the inner circumferential surface of the core receptacle 15 in order to be able to interact with the blocking element 33 of the cylinder core 17.

Abstract

L'invention concerne un dispositif de fermeture, notamment un cylindre de fermeture, comprenant un corps de base qui possède un logement de noyau, un noyau de cylindre qui est accueilli dans le logement de noyau du corps de base de manière à pouvoir tourner autour d'un axe de rotation et qui possède un canal à clé pour une clé associée au dispositif de fermeture, ainsi que plusieurs arrêts de gâchette qui font partiellement saillie à l'intérieur du canal à clé et qui sont configurés pour bloquer le noyau de cylindre, lorsque celui-ci se trouve dans une position normale, afin de l'empêcher de tourner depuis la position normale, sous réserve qu'ils ne se trouvent pas dans une configuration qui libère le noyau de cylindre, notamment par la clé associée. Le noyau de cylindre possède un élément de blocage monté mobile et précontraint dans le sens radial vers l'extérieur par rapport à l'axe de rotation, lequel est configuré pour être maintenu dans une position neutre par la clé associée en s'opposant à la précontrainte. Sur une enveloppe intérieure du logement de noyau est formée une portion de butée, laquelle définit une position limite du noyau de cylindre, différente de la position normale, jusqu'à laquelle le noyau de cylindre peut tourner librement à partir de la position normale dans la configuration de libération des arrêts de gâchette et dans laquelle l'élément de blocage, sous réserve qu'il ne se trouve pas dans la position neutre, vient en butée contre la portion de butée afin de bloquer une rotation du noyau de cylindre au-delà de la position limite.
