Definitions

  • the invention relates to a lock cylinder, in particular a profile cylinder intended for mortise locks, which is provided with a cylinder housing and a cylinder core, which is rotatably mounted therein and carries a lock bit, which can be actuated by key-operated tumbler elements and by an additional locking element against unauthorized rotation which can be actuated by means of a built-in electromagnet is to be secured.
  • Such a lock cylinder can be used in a variety of different door locks, the lock actuation, depending on the lock design and lock bolt nature different pivoting movements of the cylinder core or the key that requires it. If a key has to be turned several times in the lock cylinder, as is the case with lock bolts that can be excluded at multiple speeds, the locking element to be unlocked electromagnetically must be in its unlocking position with every full turn of the key. In addition, when the key is removed, the additional electromagnetically actuatable locking element must also return to its locking position.
  • a profile lock cylinder of the above type is the subject of the older German patent application P 37 12 300.9.
  • the electromagnet actuating the additional blocking element is operated in the open-circuit principle, the blocking element being in its blocking position when the electromagnet is de-energized. Regardless of the conventional pin tumblers, the cylinder core is only released when the electromagnet is energized. If such a lock cylinder is installed in a door lock, which requires more than one turn of the key to be actuated, then the electromagnet unlocking the locking element must be supplied with power during the entire actuation period. This period of time can be relatively long if the lock user temporarily interrupts the actuation process or even leaves the key in the lock.
  • the invention is therefore based on the object of improving and perfecting a locking cylinder of the type mentioned at the outset in such a way that its electromagnet actuating the additional locking element can be operated with the lowest possible energy consumption.
  • This object is achieved essentially in that in the cylinder core a displaceable by the key against the action of a return spring control element is arranged, which, when the key is inserted, locks the locking element displaced into its release position by brief current excitation of the electromagnet and only after removal of the key again can return to its locked position.
  • control element consists of a control pin, which is displaceably mounted in an axially parallel bore of the cylinder core and acts under the action of a locking spring acting on its one end and trying to bring it into the locking position, and provided with locking means for the locking element at the other end there is a coupling piece which is also axially displaceable and acts under the action of the return spring which is stronger than the locking spring and which is to be acted upon by the tip of the key to be inserted and thereby brought into a disengaged position lifted from the control pin and thereby releasing the latter for its locking position.
  • the locking element can nevertheless consist of a locking pin radially displaceable in the cylinder core, but also of a locking slide radially displaceable in the cylinder housing web.
  • the electromagnet and the blocking element which can be actuated by it are advantageously arranged in the longitudinal center of the locking cylinder. In this way, the adjustment stroke of the locking element and thus also of the electromagnet actuating it can be kept as small as possible, so that the electromagnet can be dimensioned comparatively weak and its power consumption is lower.
  • the invention also provides that the locking cylinder is provided, as mentioned, with a control pin forming the control element, which is displaceably mounted in an axially parallel bore in the cylinder core, and with a locking means arranged at one end, which is displaceable in the locking position of the control pin and unlocking position of the in the cylinder housing stored locking element closes a cooperating locking pocket in the cylinder, but the locking means advantageously from one at the end of the control pin facing it, which is pivotable into the locking pocket of the cylinder core, there is a locking plate.
  • a weak locking spring expediently acts on its side opposite the control pin.
  • the profile lock cylinder shown in FIGS. 1 to 5 is provided with a cylinder housing 1, in the circular cylindrical part 1 'of which the cylinder head 3 carrying the lock bit 2 or which can be coupled to it is rotatably supported.
  • This core 3 is conventionally provided with tumbler pins 5 which can be actuated by a key 4 and which - as shown in FIG.
  • the cylinder core 3 is also provided with an additional locking element in the form of the locking pin 10, which additionally protects the cylinder core 3 against unauthorized rotation and which is brought into its release position (FIG. 2) solely by brief current excitation of the electromagnet 11 housed in the cylinder housing web 1 "
  • the electromagnet 11 has an armature 11 ′′ which partially moves out of its coil winding sleeve 11 ′ when current is excited.
  • the coil winding 11 ′′ is connected via the connecting cable 111v to a corresponding power supply source, which only needs to supply brief current pulses, for example of only about 0.1 seconds, for the respective actuation of the electromagnet 11.
  • the control pin 13 which is displaceably mounted in an axially parallel bore 12 of the cylinder core 3, cooperates with the locking pin 10. It is under the action of a comparatively weak locking spring 14 which engages at one end and which tries to push it into its locking position shown in FIGS. 1 and 2. At the other end of the control pin 13, in the rest position shown in FIGS.
  • the coupling piece 15 is axially displaceable in the cylinder core 3 in its recess 3 ', which is under the action of the return spring 16, which is stronger than the locking spring 14 and can be supported on the hub of the lock bit or also a clutch body 17 conventionally accommodated therein, which is provided for the possible clutch connection between the lock bit 2 and the cylinder core 3 in one or the other of the double profile cylinder halves. 1 and 2, the coupling piece 15 is to be acted upon by the tip 4 'of the key 4, namely to bring it into a disengaged position when the key is fully inserted, in which the return spring 16 is tensioned more, but the control pin 13 is released for its locking position.
  • the locking pin 10 which is mounted essentially radially displaceably in the core bore 18, projects with its upper, laterally notched end 10 'into a lateral recess 13' on the control pin 13, whereby it is at the same time guided against rotation.
  • the flank 13 "of the pin recess 13 'facing the locking spring 14 serves in the locking position of the control pin 13 shown in FIG. 2 as a locking means for the locking pin 10, because it is thereby held in its release position raised by the current-excited electromagnet 11, for which purpose sheer frictional engagement between the locking surface 13 " and the locking pin 10 is sufficient.
  • This locking engagement can also take place in a form-fitting manner, for example in such a way that there would be a nose-like projection on the locking pin 13 in the region of the recess flank 13 ", which could engage in a corresponding latching recess at the locking pin end 10 '.
  • the other flank 13" of the pin recess 13' is also beveled, just like the locking pin end 10 'facing it, so that the locking pin 10 is thereby displaced when the control pin 13 is moved inward through its inclined surface 13''into its in FIG. 3 shown locking position can be shifted like a wedge.
  • the locking spring 14, the control pin 13, the locking pin 10 and the electromagnet 11 lie in a parallel plane offset from the pin tumblers which can be acted upon by keys.
  • its locking end 10 is provided with a bevel 10" corresponding to the associated cylinder core circumferential area.
  • the exemplary embodiment shown in FIGS. 6 and 7 differs from the one described above only by its different design of the electromagnet 19, which here, as in the case of the older German patent application P 37 12 300.9, is accommodated in a built-in housing 20 which is fitted in a cylinder housing web 1 ". laterally available, flat recess 21 directly adjoining the lock bit recess 1 "is installed.
  • the electromagnet 19 consists essentially of the iron core 23 accommodated in the recess 22 of the installation housing 20, the coil winding 24 wound around its central web 23 'and the armature lever 25 lying flat on the bottom of the recess 22. At the free end of the armature lever 25 this sits with the Locking lever 10 cooperating anchor part 26.
  • the design of the locking pin 10, the control pin 13 cooperating with it and the arrangement of the locking spring 14, the coupling piece 15 and the return spring 16 correspond to the embodiment shown in FIGS. 1 to 5.
  • the locking element consists of a locking slide 27 radially displaceable in the cylinder housing web 1 ", which is firmly connected to the armature of the electromagnet 11 housed in the same web bore 11v.
  • the locking slide 27 is under the effect of it in the shown locking position to press the locking spring 28.
  • the locking slide 27 is pulled out by short current excitation of the electromagnet 11 from the locking slot 29 present in the cylinder core 3.
  • Bearing control pin 13 provided with a locking means forming wing 13 1v , which also protrudes into the locking slot 29 and in the locking position of the control pin 13 indicated by dash-dotted lines in Fig. 8 protrudes into the path of movement of the locking slide 27 and thereby briefly in its by the electromagnet 11 unlocked position.
  • the mode of operation of the control pin 13 corresponds entirely to the function of the control pin 13 present in the aforementioned exemplary embodiments.
  • the lock cylinder described above with its electromagnetically actuated locking element is particularly suitable for electronic lock cylinders in which the key, in addition to its conventional mechanical identification features, namely its key cuts and its key profile, also has one or more electronic identifications, as a result of which mechanically identical keys are additionally distinguished and are authorized can be checked so that the usual functions of electronically operating access systems can also be performed in conventional cylinder locking systems.
  • a control with evaluation electronics and power supply is assigned to each such lock cylinder. It is essential to keep these cylinders and their associated electronics as simple as possible and to be able to install them. Battery operation is the best option for this. Since the current consumption in the new lock cylinder is extremely low, such an electronic cylinder can be operated much longer with the battery provided. Furthermore, no special signal transmitter and control measures are necessary to allow the additional locking element to reach the locking position, since this occurs automatically as soon as the key is removed from the cylinder core.
  • the control pin 13 could also be brought into the locking position directly by the inserted key and held therein.
  • plug couplings can be used, such as those found in the embodiment shown in FIGS. 8 and 9 in the form of the plug pins 31 arranged in a lower recess 30 in the cylinder housing web 1 ".
  • This plug coupling is special then useful if in each of the two halves of the profile double cylinder an electromagnet 11 or 19 in is installed. If the electromagnet is only seated in one half of the cylinder, the connecting cable could easily be firmly connected to the electromagnet, but the connecting cable should then be appropriately protected by a grommet adapted to the cylinder housing.
  • the profile lock cylinder shown in FIGS. 10 to 13 is also provided with a cylinder housing 41, in whose circular cylindrical part 41 ' the cylinder core 43 which carries the lock bit 42 or can be coupled to it is rotatably supported.
  • This core 43 is conventionally provided with tumbler pins 45 which can be actuated by a key 44 and which cooperate with the housing pins 48 which are displaceably mounted in the cylinder housing web 41 ′′ in the bores 46 provided there and acted on by tumbler springs 47.
  • the cylinder core 43 is additionally secured against unauthorized rotation by an electromagnetically actuated tumbler.
  • This consists of the locking element 52 forming the armature of the electromagnet 51, which acts under the action of the armature spring 53 acting on its head 52 ' , which tries to press the locking armature 52 into the locking pocket 54 provided on the circumference of the cylinder core.
  • the electromagnet 51 is arranged with its armature 52 and its spring 53 in the longitudinal center of the cylinder housing 41 ′′, namely in a somewhat enlarged housing bore 55, which is therefore in the same plane as the housing locking holes 46.
  • Correspondingly in the center of the profile cylinder or on the circumference of its Core 43 also contains the locking pocket 54. As shown in FIG.
  • this has a slightly larger diameter than the head 52 ′ of the armature 52 of the electromagnet 51 forming the locking element. This ensures that the armature 52 is not even with slight swiveling or axial movements of the inserted key and thus also of the cylinder core 43, the electromagnet 51 would prove to be too weak under certain circumstances.
  • the undercut 52 "present on the head 52 'of the armature 52" increases the locking engagement security.
  • the control pin 57 is slidably mounted in the axially parallel bore 56. It protrudes with its end 57 'into a recess 58 of the cylinder core which runs transversely to the cylinder axis and tangentially contacts the locking pocket 54.
  • recess 58 contoured in the form of a segment of a circle the correspondingly contoured and slightly angled locking plate 59 is accommodated with an axial pivoting play. It is held by the weak locking spring 60 housed in the core 43 at the end 57 'of the control pin 57. At the other end of the control pin 57, in the rest position shown in FIG.
  • a coupling piece 61 which cannot be rotated but is axially displaceable in the recess 43 'in the cylinder core 43, has an insertion pocket 61' for the tip of the key 44.
  • the coupling piece 61 is above the coupling pair 62 under the action of the return spring 63, which is stronger than the locking spring 60 and which can be supported on the coupling body 64 accommodated in the other cylinder core half.
  • the return spring 63 could equally well be arranged between the coupling body 61 and the coupling body pair 62.
  • the coupling bodies 61, 62 and 64 are designed in a known manner so that they are able to couple the core of this cylinder half after respective insertion of the key into a lock cylinder half after a corresponding axial displacement while simultaneously disengaging the other cylinder core with the lock bit 42 so as to be rotationally driven.
  • the electromagnet 51 inserted into the bore 55 of the cylinder housing web 41 "has a sleeve 51 'carrying the coil winding. Its bottom 51" consists of soft iron and has a concave recess 51 "". The end of the recess 51 opposite this Electromagnetic armature 52 has a correspondingly convex projection 52 "'. As has been shown, the magnetic field present between the electromagnet armature 52 and the coil sleeve base 51 "is considerably amplified, which is particularly important for the initial tightening of the electro armature 52, which is therefore the furthest distance from the coil sleeve base 51".
  • a ball detent to hold the latter in its rest position, which consists of the detent ball 66 located in the radial bore 65 of the cylinder core 43 and the spring 67 acting on it and the detent recess 68 present in the cylinder housing. This measure also helps to keep the blocking anchor 52 as low-friction as possible at the time of its release movement.
  • the cylinder housing web 41 " is also provided on the end face with a plastic cover cap 69, which is clipped onto the housing web 41" correspondingly flattened in its push-on area. With its bottom 69 ', it engages under the outermost tumbler bore 46', in which, in addition to the housing pin 48 'and the tumbler spring 47', a permanent magnet 70 is slidably mounted, which via a reed contact, not shown, arranged in the housing web 41 "
  • the control electronics can be brought into corresponding data and energy exchange via the detector coil 71 provided in the plastic cap 69 with an electronic coding accommodated in the key 44.
  • the tumbler pins 45, 48 are inserted in the conventional manner Parting plane 49 between core 43 and lock cylinder housing 41 shifted.
  • the control electronics are switched on via the permanent magnet 70 which is correspondingly displaced when the key is inserted, which in turn ensures brief current flow through the electromagnet 51, as a result of which the electromagnet armature 52 is disengaged from the locking pocket 54.
  • the coupling bodies 61, 62 Since, together with the key insertion, the coupling bodies 61, 62 have also been displaced so that they have been lifted off the control pin 57, the latter can be axially displaced under the influence of the weak locking spring 60 and thereby pivot the locking plate 59 into the recess 54, thereby causing the Electromagnetic armature 52 allowed to hold in its unlocking position shown in FIGS. 11 and 12.
  • the electromagnet 51 therefore does not need to remain energized for the unlocking of the cylinder core 43. If the key 44 is withdrawn from the cylinder core 43, the control pin 57 is thereby displaced via the correspondingly displaced coupling bodies 61, 62 by the return spring 63 into its rest position shown in FIG.
  • the energy-saving central arrangement of the electromagnet 51 can also be used in the case that its blocking element which can be acted upon by it is accommodated not in the cylinder housing but in the cylinder core, because even then the blocking plate 59, with a correspondingly different installation method, has the blocking element in it would allow locking position to lock. It is also fundamentally possible, with the appropriate design and arrangement, to let the locking plate reach the locking position solely under its own weight and to be able to move the control pin 57 relieved of its return spring 63. However, the locking spring 60 deserves preference for this, since it ensures greater switching reliability.
