Definitions

  • the invention relates to a device that can be mounted on doors that are equipped with a conventional cylinder-operated lock and that serves for manual actuation of the bolt and the latch of such a lock in conjunction with an electrical signal that an electromagnetic coupling device with very little Current consumption effectively controlled, as well as the advantageous safety and operational design of the entire closure device.
  • the solution is based on the fact that a drive axis is guided coaxially through an output axis from the outside of the door into the mechanical lock itself or on the inside of the door, that a first gearwheel is connected to the drive axis and a disk which forms part of an electromagnetic coupling device, that the output shaft is connected to a second gear and a cam, which the actuation of bolt and latch locks of conventional design is used that a pivot plate is mounted about the output axis, which carries the other part of an electromagnetic coupling device which, when energized by the disc, which is part of the drive axis, is pivoted out to a mechanical stop , The electromagnetic coupling device now passes into a slip when the drive axis continues to rotate.
  • the security-critical area of mechanical locks lies in the area of the lock cylinder and in the area of the lock tumblers above.
  • the critical area is reduced to the lock cylinder itself, because this must necessarily be exposed due to the key insert. If it is possible to remove the locking cylinder or parts of it by using force, all protection against unauthorized opening of a door is eliminated.
  • the danger described for mechanical locks applies in the same way to the locking device dealt with here, since it is mounted on a conventional mechanical lock and also uses a locking cylinder which is sensitive to the use of force on the outside of the door.
  • the invention has for its object to provide a much more wear-free, easy to use locking device with less force, which is safer against external use of force and against low battery voltage, which can be operated directly mechanically from the inside of the door and which otherwise have all the advantages of the above Locking device preserved.
  • the drive axis can be guided to the outside of the door at a distance from the output axis below the mechanical lock.
  • the output shaft engages the hollow shaft of a special locking cylinder from the inside of the door, enters into a non-rotatable connection with it and the special locking cylinder operates the latch and bolt of the mechanical lock with its locking cam. Since this special locking cylinder is a half cylinder and only has a connection to the inside of the door, but not to the outside of the door, the solution, which is favorable for security reasons, results in all security-critical areas of the mechanical lock and the special locking cylinder on the outside of the door with a drill-protected steel plate totally without any To be able to cover the opening in the safety-critical area. This solution is characterized in detail in claim 10.
  • the output axis of the coupling device accessible on the room side provides the advantageous possibility of mechanically actuating the lock directly from the inside of the door.
  • the current through the holding magnet is switched on automatically when the desired swivel position is reached.
  • the measures characterized in claim 7 result in the advantageous possibility of dispensing with a separate reserve switch and integrating it into the normal code entry keyboard.
  • the measures characterized in claim 8 result in the advantageous possibility for safety reasons, if necessary, to decouple the actuating part attached directly to the inside of the door mechanically driving the lock and to lock it in the decoupled position. This is important for safety reasons in the case of doors with a glass insert, where the direct drive for the lock could otherwise be operated after the glass insert has been destroyed and it has been reached inside.
  • the closure means comprises a common mechanical lock cylinder.
  • the measures characterized in claim 10 result in an arrangement which reliably protects against violent attempts at opening from the outside, since, in contrast to all conventional lock cylinders or locks, all security-critical areas of the lock and lock cylinder can be effectively protected by a drill-protected steel plate without any cylinder opening .
  • Fig. 1a the coupling device is shown in a sectional side view.
  • the drive axle 1 which can be driven from the outside of the door, is firmly connected to a gearwheel 2.
  • a gear 3 With this gear 2, a gear 3 is in constant engagement, which is rotatably mounted about the axis 4 and is used for power transmission and reversal of direction.
  • the gear 3 is in turn in constant engagement with a gear 5 which is freely rotatable about the output axis 6.
  • a disc 7 is rotatably connected consists of soft magnetic material and which is part of an electromagnetic coupling device which serves to pivot a pivot lever 8 made of non-magnetic material.
  • the second part of the electromagnetic coupling device is formed by the swivel magnet 9; which is preferably designed as a U-magnet and carries a coil 10 for generating a magnetic flux.
  • the contacting surfaces of the swivel magnet 9 and the disk 7 are ground in such a way that the air gap between the two parts is very small. This results in a large magnetic flux even with very little electrical excitation and thus a strongly attractive force between the disk 7 and the swivel magnet 9.
  • the disc 7 With the rotation of the axis 1, the disc 7 is rotated at the same time, so that when the pivot magnet 9 is excited, the pivot lever 8 also rotates by a predetermined angle.
  • a further, mainly U-shaped holding magnet 11 is fastened on this pivot lever 8 and can be excited by means of a coil 12.
  • the magnetic circuit for this magnet is closed by a sheet 13 which is fixed to the housing.
  • the contacting surfaces of the holding magnet 11 and the sheet 13 are also ground in such a way that the air gap between the two is very small.
  • the pivot lever 8 has run-on bevels 16, 17, 18, 19 which, when the pivot lever 8 rotates, axially move a further plate 20 arranged coaxially to the latter.
  • a rotationally fixed connection of the sheet 20 to the housing by means of a bracket 21 results in the axial displacement of the sheet 20 as the pivot lever 8 rotates.
  • a driver 22 which is mounted in a milled axis 6, is moved upwards against a spring 23 until it engages fully in pins 24 which are connected to the gear wheel 5. This creates a connection between the drive axle 1 and the output axle 6, via which very large forces can be transmitted.
  • the current supply for the pivot magnet 9 occurs only in such angular positions of the output axis 6 relative to the gear 5 that the driver 22 always is pushed up in the space between the pins 24.
  • one end of the winding of the coil 10 is connected to the housing, that is to say to ground.
  • the power supply to this winding end is carried out on a plate 25 which is mounted insulated from the housing.
  • a further insulating part 26 is attached between the plate 25 and the disk 7, which is connected to the axis 6 and is also rotated by it.
  • Contact springs 27 are arranged in two recesses of this insulating part 26 and cause a current transmission from sheet 25 to the disk 7 and thus to the coil 10.
  • the disc 7 now carries on its side facing the contact springs 27 a printed insulating layer in those segments in which a current supply to the coil is undesirable. This ensures that the coil 10 can be energized relative to the axis 6 only in those angular ranges of the gear wheel 5 in which it is possible to lift the driver 22 without bumping against the pins 24.
  • Fig. 3 the circuit for energizing the coils 10, 12 of the two magnets 9, 11 is shown in more detail.
  • the switch 28 is formed by electronics which, after the correct code input, connects a voltage source 29 to the coil 10 of the swivel magnet 9. 32 switched diodes 31, 29 back to the voltage source - thus closing the switch 28 with a current flows via a resistor 30 across the coil 10 and through one or more ge in the forward direction.
  • the resistances of the coils 10 and 12 are selected in connection with the resistor 30 and the threshold voltage formed by the diodes 31, 32 so that the current through the coil 12 largely drops to zero as the current flows through the coil 12.
  • a resistor 33 is connected in parallel with the resistor 30.
  • This switch can be closed by a button 34, which is labeled "reserve”, whereby the resistor 30 has no current-limiting effect and the current flow is increased for the period of time the button 34 is closed.
  • This is very advantageous for avoiding problems due to low battery voltage and at the same time very useful as an indication for the operator that a battery change is required.
  • This key 34 can be integrated into the existing code entry keyboard of the locking device.
  • the key 34 is at the same time a function key of this keyboard and, in addition to its function label as a code entry element, bears the label "Reserve”.
  • FIG. 4 shows the overall structure of a locking device with a locking cylinder and a coupling device with offset axes.
  • the entire security-critical lock area is covered by a steel plate 35 which is screwed to the inside of the door.
  • a small opening in the lower area of this steel plate leads an axis 1 below the lock - and thus in the safety-neutral area - to the outside of the door.
  • the dome is activated via axis 1 when the swivel magnet is energized direction 36 initiated a rotational movement in the correct direction of rotation in the cylinder 37.
  • the coupling device 36 is not energized, the axis 1 can be freely rotated.
  • the axis 1 is rotatably connected to the rotary knob 38 by an intermediate axis 39.
  • the intermediate axis 39 By a suitable selection of the intermediate axis 39 from a set of axes stepped in length, the locking device can be easily adapted to any door thickness when retrofitted.
  • the output shaft 6 is accessible from the rear of the coupling device 36 and thus allows the locking cylinder 37 to be driven directly from the inside of the door by means of an actuating part 40.
  • This is rotatable in the inner fitting 41, which covers all components of the inside of the door, and can be pulled out against a spring force. By pulling out the actuating part 40 by a few millimeters, the mechanical coupling to the coupling device 36 is canceled.
  • a pivotable sheet 43 located on the coupling device 36 can be folded between the actuating part 40 and the coupling device 36.
  • the coupling of the actuating part 40 to the coupling device 36 is thus permanently eliminated.
  • Another solution for decoupling a fixed - i.e. non-extractable - actuating part 40 from the output axis 6 consists in integrating a connecting plate (not shown in the drawing) with a lateral bevel in the actuating part 40, which engages in the slotted axis 6 and by one in the actuating part 40 located spring remains pressed.
  • the connecting plate When the actuating part 40 is in the correct position, in which the connecting plate is perpendicular to the cover plate 43, the connecting plate can be pushed into the actuating part 40 through the cover plate 43 due to the lateral bevel. The coupling of the actuating part ' s40 to the axis 6 is thus eliminated.
  • the cover plate 43 is designed to be lockable in its covering pivoting position by a mechanical lock 42 - preferably a lock cylinder. It is particularly advantageous that the same locking cylinder can still be used as a programming cylinder, the user of the locking device being able to feed in or change the locking information stored as a code of the locking device as soon as he has brought the key of this locking cylinder into a certain other position. Because only in this position is a switch, not shown in the drawing, actuated, which only activates program switching means not described here in the switched-on state and not shown in the drawing.
  • the lock cylinder 37 which causes the movement of the lock bolt when inserted in the lock 44, contains a hollow shaft 46 with a driving groove, to which the locking / opening cam 45 is firmly connected.
  • the output shaft 6 protrudes into this hollow shaft and transmits a rotary movement from the output shaft 6 to the closing / opening cam.
  • the depth of insertion of the output shaft 6 into the hollow shaft 46 is variable over a predetermined distance.
  • FIG. 5 shows the design of the special locking cylinder 37 in a detailed form.
  • a hollow shaft 46 which is fixedly connected to the cam 45, is inserted into the cylinder body so that it is only accessible from one side. The other side of the cylinder is closed and can be protected against drilling by a steel pin 47.
  • Fig. 5 the execution as a profile cylinder is shown. However, the execution is also possible as a round or oval cylinder or in any other external shape.
