Definitions

  • the invention relates to a locking 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 is to be secured against unauthorized twisting by means of tumbler elements which can be acted upon by a key and a locking element which can be actuated by means of an electromagnet. and wherein control electronics actuating the electromagnet and associated power supply switch are provided.
  • Lock cylinders of the above type are known, for example, from AU-PS 320466.
  • the control electronics are housed in the lock case containing the profile cylinder.
  • a microswitch is built into their power supply line, which, when the cylinder core is rotated, has a mechanical and electronic coding that matches it provided key can be actuated either by a pivoting tumbler plate or by a cam disc that is fixed on the cylinder core next to the lock bit.
  • a profile lock cylinder known from DE-OS 3501345, which is also provided with an electromagnetic tumbler, some of its tumbler pins serve as switching contacts via which an intrusion detection system can be armed.
  • the invention is therefore based on the object of providing a locking cylinder of the type mentioned at the outset which does not have the abovementioned shortcomings, but rather ensures simple, undisturbed and energy-saving power supply for the associated control electronics.
  • This object is achieved in that the power supply switch belonging to the control electronics is designed as a magnetosensitive switch accommodated in the cylinder housing, the actuating magnet of which is coupled in terms of movement to one of the housing-side tumbler elements. This ensures that when the appropriate key is inserted, the actuating magnet is brought into the closing, shifting positions like a tumbler element in the magnetosensitive switch and thus the control electronics are supplied with power. Since the magneto-sensitive switch works without contact and is not exposed to any risk of corrosion or contamination, it remains permanently functional with a consistently low electrical contact resistance.
  • the actuating magnet is advantageously designed as a cylindrical-pin-shaped permanent magnet and in the outermost tumbler bore between the housing pin therein and its actuating spring arranged, the magnetosensitive switch is further accommodated in a housing recess which is adjacent to the aforementioned tumbler bore, in particular runs parallel to the latter and is laterally offset relative to the other tumbler bores.
  • the magnetosensitive switch is advantageously designed as a reed contact. However, it can also be designed as a Hall sensor or as a Wiegand sensor.
  • the lock cylinder can also be provided in a manner known from DE-OS 3500353 with a detector attached to the end of the cylinder housing for electronic data and energy exchange between control electronics and key, whereby according to a further feature of the invention the cylinder housing is covered on the end side by a plastic cap containing the detector which also engages under the outermost housing tumbler pin hole.
  • a plastic cap containing the detector which also engages under the outermost housing tumbler pin hole.
  • the plastic cap is expediently clipped onto the cylinder housing, whereby it protrudes with a projection on its bottom into the housing locking pin bore which it covers on the underside and, with its upper concave edge edge, engages behind a collar projection provided on the end face of the cylinder core and provided with a corresponding undercut.
  • the plastic cap can easily be mounted on the correspondingly flattened cylinder housing in this area. With an appropriate surface finish, it also ensures an appealing appearance of the locking cylinder section protruding from the door fitting.
  • the profile lock cylinder shown in Figs. 1 and 2 has a correspondingly profiled cylinder housing 1, in the hollow cylindrical region 1 'of the rotatably mounted cylinder core 2 is housed. On its opposite side there is a further, correspondingly rotatably mounted cylinder core 2 '. Between the two cylinder cores is rotatably supported in the housing recess 1 ⁇ of the locking bit 3, which can be coupled to the respective associated cylinder core 2 for rotary driving via the rotatably connected coupling pieces 4 and their axial displacement when the key 5 is inserted.
  • the key channel 6 provided with corresponding profile ribs in the cylinder core 2 serves to receive the key 5 to be inserted.
  • the cylinder core 2 is rotationally locked to the cylinder housing 1 by means of pin tumblers of conventional designs.
  • These tumblers consist of the core and housing bores 2′′′ or 1 ′′′ seated core pins 7 and housing pins 8 and the pressure springs 9 acting on the latter.
  • the key cuts or notches 5 'present in the key shaft make the tumbler pin pairs 7, 8 at Inserting the key 5 so displaced against the action of its springs 9 that the joint 10 located between each pin pair comes into agreement with the separating surface 11 located between the cylinder housing 1 and cylinder core 2, so that the core 2 relative to the housing 1 by means of the inserted key 5 could basically be twisted.
  • the core 2 is additionally blocked against rotation by the armature 12 of an electromagnet 13, which acts as a locking bolt and is accommodated in the bore 14 of the cylinder housing 1.
  • the head 12 'of the armature 12 engages under the action of the compression spring 15 in a recess on the cylinder core 2 on its circumference 16.
  • To actuate the electromagnet 13 and its armature 12 is a not shown, in the castle or better still on the inside of Control electronics housed in the door fitting, which, via the detector 17 mounted on the end face of the cylinder, with the key 5, which also contains a non-mechanical coding, in mutual electronic data and bring energy exchange.
  • the control electronics respond and ensure that the electromagnet 13 is briefly acted upon by current. As a result, its armature 12 moves out of the recess 16 in the cylinder core 2, causing the latter to twist and thus correspondingly close the Castle can be made.
  • the power supply to the control electronics is expediently carried out in an energy-saving manner by means of a battery (not shown), if possible also accommodated on the inside of the fitting.
  • the magnetosensitive switch in the form of the reed contact 19, which is accommodated in the recess 18 in the cylinder housing 1, is installed in the power supply line leading to the control electronics.
  • the magnet required for its actuation is designed as a cylindrical-pin-shaped permanent magnet 20 which is accommodated between the housing pin 8 'seated in the outermost housing bore 1 IV ' and its actuating spring 9 '.
  • the magnet 20 is so as the pin 8 'slidably mounted in the housing bore 1 IV .
  • the front side of the cylinder housing 1 is covered by a plastic cap 21, which forms the detector 17 and forms a coil of the control electronics, which also has the outermost one Housing magnet containment pin bore 1 IV engages under permanent magnets 20.
  • the plastic cap 21 is clipped onto the cylinder housing 2 in such a way that it protrudes with a projection 21 'present on its bottom into the housing retaining pin bore 1 IV covered by it on the underside, while with its upper concave-shaped edge 21' behind one present on the end of the cylinder core 2 , with an appropriate undercut 2 ′′′ provided collar projection 2 IV .
  • the plastic cap 21 is flush with the outside in the overlap area on both sides and below with corresponding flats 22 and 22 'provided cylinder housing 1.
  • the plastic cap 21 protrudes somewhat over the end face of the cylinder core 2, whereby the detector coil 17 housed in the plastic cap in the End face 5 ⁇ of the key 5 housed counter detector can come particularly close.
  • a horizontally running longitudinal cable channel 23 is cut out on one long side of the cylinder housing 1, which merges into a vertically running transverse cable channel 24 on the end face.
  • the power lines shown by the coil detector 17 and by the reed contact 19 can be passed gently, so that they do not interfere with the assembly of the profile cylinder in the lock, especially since they or the like in the channels 23, 24 by resin can be set. Like the control electronics, these lines are not particularly shown in the drawings.
  • the reed contact 19 is first closed via the correspondingly displaced permanent magnet 20 and the power supply to the control electronics is thus switched on.
  • the latter ensures that the electromagnet 13 is briefly flowed through by current, whereby its anchor bolt is pulled out of the recess 16 in the core and the core is released for its rotation by the inserted key, after the mechanical tumbler pin pairs have already been correspondingly adjusted and thereby brought into the separation position between core 2 and cylinder 1.
  • the release position of the anchor bolt 12 can be maintained by means not shown here until the key 5 is extracted again.
  • the electromagnet 13 therefore only needs to be flowed through by the current for a short time.
  • a further requirement for a correspondingly energy-saving battery operation of the electronic cylinder 13 is that the control electronics be switched on by the permanent magnet 20 acting on the reed contact. This switching on takes place for a short period of time both when the key 5 is inserted and when it is removed.
  • the reed contact 19 can in principle also be replaced by a Hall sensor or a Wiegand sensor of known design and mode of operation, as a result of which the control electronics can also be switched on in conjunction with a key-operated pin tumbler.
  • the cap 21 is advantageously made of insulating plastic. It makes the locking cylinder protruding a maximum of 3 mm from a security shield optically advantageous and at the same time difficult to attack.
