Definitions

  • the invention relates to a codable cylinder lock with at least one locking body secured against rotation and at least one cylinder body rotatable about an axis of rotation by means of a key relative to the locking body, and with tumblers which can be displaced in recesses in the cylinder body and the locking body, at least some of which, when the lock is locked, at least one Interface between the locking body and the cylinder body penetrates, wherein the formation of at least part of the tumblers can be changed.
  • the tumblers After the filler pieces have been moved, the tumblers, the design or the displacement of which has been changed by removing or inserting filler pieces, have to be respectively further or less far than previously in the recesses of the magazine and by means of a new key adapted to the recoded lock the guide parts are moved until the end faces of the locking pins coincide with the parting surfaces, so that the lock can be opened.
  • the key has an annular cross-section, with axial grooves of different lengths being arranged in its end facing the lock, engaging in the actuating pins, which protrude beyond an annular end face of the guide part of the lock facing the key.
  • DE-U1-91 13 193 discloses a codable cylinder lock with a cylinder body rotatable about an axis of rotation and a locking body which bears against the circumferential surface of the cylinder body and is secured against rotation, in which the coding of the lock and the key can be reversibly changed .
  • the cylinder lock there has a blocking device which can be moved radially in the cylinder body and which, when the lock is locked, passes through a separating surface between the cylinder body and the locking element.
  • several locking elements are arranged axially parallel, each of which is provided with a recess on its upper side and can be displaced with the aid of the key.
  • the recesses are offset according to the key secret arranged that when the lock is locked, a blocking web of the blocking device rests against the top of the locking elements, which are displaced when inserting a key adapted to the coding of the lock so that the recesses below the web align with one another, so that the web when the cylinder body rotates can be pressed inwards into the recesses and the engagement of the blocking device in the blocking body can be canceled.
  • the number of possible codings is limited, however, because due to the limited space available, only a few locking elements (four in the illustrated embodiment) can be accommodated in a cylinder body, the exchange of which in the illustrated embodiment results in only 24 different codings.
  • the invention is based on the object to improve a cylinder lock of the type mentioned in such a way that a recoding of the lock is possible while the old key is still used, with a number of coding options remaining large.
  • the coding of the cylinder lock can be changed by changing a mutual arrangement and / or a number of tumblers that pass through the separating surface, and that the key can be changed both to a changed number and to one modified arrangement of the tumblers penetrating the interface is reversibly adaptable.
  • Mutual arrangement of the tumblers penetrating the dividing surface is understood to mean the relative position which the tumblers which do not penetrate the dividing surface when the lock is locked compared to those tumblers which penetrate the dividing surface.
  • the two coding criteria, number and arrangement can be freely selected independently of one another, so that there is a large number of coding options which can be set as desired.
  • the features of the invention further ensure that if one of several keys is lost or stolen as a precaution against unauthorized opening of the lock by third parties, it is sufficient to transcode the lock and the other keys.
  • the key is recoded simply by adjusting actuators for the tumblers, so that neither an exchange of parts nor the involvement of a specialist company is necessary.
  • the coding can furthermore be reversibly changed by changing a displacement path of at least one tumbler, ie the path which is required to shift the tumbler from a locked position into an open position, and at the same time also the key to a changed displacement path reversibly adaptable.
  • This measure can the already existing large number of coding possibilities are raised again, since this criterion is independent of the other criteria.
  • Another preferred embodiment of the invention provides that the cylinder body and the locking body are arranged one behind the other in the direction of the axis of rotation, and that the cylinder body and the locking body each have mutually aligned recesses in which the tumblers under the action of at least one compression spring are longitudinally displaceable .
  • an axial distance between an actuator of the key interacting with the tumblers and an end face of the key that can be placed against an end face of the cylinder body can be reversibly changed. In this way, all coding criteria of the lock can be taken into account with one setting per tumbler.
  • a further preferred embodiment of the invention provides that the tumblers have at least one actuating pin projecting over an end face of the cylinder body, and that the key has axial recesses for engaging the actuating pins on at least one end face which can be placed against the end face, the length of the recesses is changeable.
  • the recesses of the key are limited in the axial direction by stop faces of the actuating members rotatably mounted in the key, which are expediently rotatable about axes of rotation which are aligned parallel to the longitudinal axes of the actuating pins and are offset with respect to these.
  • Another advantageous embodiment of the invention provides that some of the tumblers have at least one locking core which, when the lock is locked, passes through the separating surface or the separating surfaces between the cylinder body and the locking body, while the locking cores of the remaining tumblers have end faces arranged in the separating surface, so that these tumblers do not secure the cylinder body against rotation even when the lock is locked.
  • both the number and arrangement of the tumblers, the locking core of which passes through the separating surface, and the number of locking cores of each tumbler and thus their displacement path can be changed.
  • the tumblers being common to both cylinder bodies.
  • the tumblers expediently penetrate both cylinder bodies and the locking body and each have two actuating pins, between which a different number of locking cores are arranged.
  • the locking cores of the tumblers provided with a locking core each have end faces arranged in the separating surface when the lock is locked and therefore must not be displaced when the key is inserted, since their locking cores would otherwise penetrate one of the separating surfaces and thus prevent the cylinder body from rotating, which are also used two or more locking cores provided tumblers when the lock is locked, the two separating surfaces between the locking body and the cylinder bodies and must therefore be moved so far when the key is inserted until the end faces of one or more locking cores coincide with the separating surfaces, in which case a locking core with which Key facing cylinder body is rotated while the remaining locking cores are between the parting surfaces of the locking body.
  • a further embodiment of the invention provides that the key has two opposing end faces which can be placed against end faces of the cylinder body, with a reversibly variable axial distance between one cooperating with one of the tumblers actuator of the key and the two end faces is the same, so that the key can be pressed with one end face from the outside against one end face and with the other end face from the inside against the other.
  • the double cylinder lock 1 shown in the drawing consists essentially of a locking body 6 secured against rotation in a lock case 4, two cylinder bodies 12, 14 rotatable by means of a key 8 with respect to the locking body 6 about an axial axis of rotation 10, and a plurality of tumblers 16 which Distributed in a ring shape around the axis of rotation 10, the locking body 6 and the cylinder body 12, 14 are displaceably mounted in the axially extending recesses 20, as well as a drilling security device 24 inserted in a continuous central stepped bore 22 of the cylinder lock 1.
  • the locking body 6 has the shape of a disc 26, which is in the axial direction of the recesses 20 and the stepped bore 22 is penetrated, and over the cylindrical peripheral surface 28 a comb 30 with a cylindrical peripheral surface 32 protrudes, which is offset in the axial direction by annular shoulders 34 with respect to the peripheral surface 28 of the disk 26.
  • the comb 30 has two diametrically opposite recesses 36, 38 arranged laterally in the lock case 4 in the installed state, which are delimited at the top and bottom by parallel guide surfaces 40.
  • the cylinder bodies 12 and 14, each bearing against an end face 42 or 44 of the locking body 6, are essentially cylindrical in shape and have indentations 46, 48 on their ends facing the locking body, each of which has an edge projecting axially from an end face 50, 52 53,57 are limited, the inner and axial boundary surfaces abut against the annular shoulders 34 of the locking body 6.
  • the recesses 20 are formed as stepped bores 54, which are introduced from the end face 50, wherein a compression spring 56 is inserted into the recesses 20, which is in the direction of an axial end face 58 of the cylinder body 12 against an annular shoulder 62 of the stepped bore 54 supports.
  • the cylinder body 14 is, in contrast, formed in two parts, the compression springs 56 are each inserted into a bore 61 of a receiving part 59 facing the locking body 6 and are supported against an end face 63 of a cap-shaped end part 65 which is placed on the receiving part 59 and on this by grub screws 67 is held, which are screwed from the outside into threaded bores of the end part 65 and into radial bores of the receiving part 59 engage.
  • the tumblers 16 inserted into the recesses 20 against the force of the compression springs 56 in the axial direction to each side consist of two actuating pins 64, between their facing ends 66 in the embodiment shown in FIGS. 2 and 3 in accordance with a desired coding or two locking cores 68 are loosely inserted.
  • a recoding of the lock 1 takes place in this embodiment either by changing the number of tumblers 16a or 16b with one or two locking cores 68 by adding or removing a locking core 68 for one or more tumblers 16a or 16b, or by changing the mutual arrangement, ie the sequence of adjacent tumblers 16a or 16b with one or two locking cores 68 is changed in that locking cores 68 are removed one or more times from a locking device with two locking cores 68 and inserted into a locking device with a locking core.
  • a change in both criteria, i.e. the number and the mutual arrangement is of course also possible.
  • the number of locking cores 68 of a tumbler 16 in the exemplary embodiment of FIGS. 12 and 13 can be between one and four, so that a recoding by changing the displacement path of at least some of the tumblers 16 is in each case replaced by a tumbler 16 with a larger or smaller one Number of locking cores 68 takes place, alternatively to or simultaneously with a change in the number and / or arrangement of the locking cores with a locking core. Since both the number of tumblers with one, two, three or four locking cores 68 as well as their mutual arrangement can be changed, the number of possible codings is enormously high.
  • the actuating pins 64 each have an enlarged Part of the stepped bore 54 of the cylinder body 12 or in the bore 61 of the receiving part 59 slidably guided, supported against the compression spring 56 and resting against a locking core 68, and a head part 72 in the unloaded state by a predetermined amount over the axial end faces 58, 60 Cylinder body 12, 14 protruding actuating part 74, which is slidably guided in the narrower part of the stepped bore 54 or in a bore 55 of the end part 65.

  • the outer edge of the end face 70 is chamfered in each case in order to facilitate the insertion of the locking core 68 into the recess 20.
