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 Power consumption effectively controlled, as well as the advantageous safety and operational design of the entire firing 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 is used to actuate bolts and latches of locks of a conventional type, that a pivot plate is mounted around the output shaft, which carries the other part of an electromagnetic coupling device which, when energized, by means of the disc, which is part of the drive axle, is pivoted out to a mechanical stop, the electromagnetic coupling device now passing into a slip as the drive axle continues to rotate.
  • the electromagnetic coupling device which is used for the mechanical coupling of a gear transmission, must remain energized during the entire operating time, because otherwise the gear transmission is coupled out again by means of return springs.
  • the resulting slippage between the two parts of the electromagnetic coupling device results in mechanical abrasion of the parts, which limits the service life of the entire device.
  • the operator must apply additional forces when operating the lock, because the frictional forces caused by the electromagnetic coupling device must be applied in addition to the lock operating forces.
  • 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, any 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 mechanically directly 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 that 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 without being able to cover every 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 6 provide a simple indication that the battery voltage is approaching a critically low point and that a battery change will soon be necessary. After entering this state, the user is reminded of this need each time it is used, until he remedies it and changes the batteries.
  • 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 measures characterized in claim 9 result in the advantageous possibility of using a common mechanical locking cylinder for closing the inner actuating part in the uncoupled position and for securing against unauthorized reprogramming or reprogramming of the codes of the locking device.
  • the measures characterized in claim 10 result in an arrangement which reliably protects against violent opening attempts coming from the outside, since, in contrast to all conventional locking cylinders or locks, all security-critical areas of the lock and locking 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 on the axis 4 and serves for the transmission of force 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 to the gear wheel 5, which is made of soft magnetic material and which is part of an electromagnetic coupling device which serves to pivot out 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 magneti flows cal flux from one leg of the magnet back through the disc 7 to the other leg. This will firmly tighten the disc on the U-shaped magnet.
  • 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 comes with rotation of the swivel.
  • lever 8 the axial displacement of the sheet 20 is achieved.
  • 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 driven axle 6, via which very large forces can be transmitted.
  • the current supply for the swivel 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, which cause a current transfer from sheet metal 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. When the switch 28 is closed, a current flows back to the voltage source 29 via a resistor 30, the coil 10 and one or more diodes 31, 32 connected 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 means of a key 34, which is designated “reserve”, as a result of which the resistor 30 has no current-limiting effect and the current flow is increased for the period of the key 34 being 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 also a function key on 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.
  • 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 40 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 firmly connected to the cam 45, is inserted into the cylinder body so that it is accessible only on 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 design is also possible as a round or oval cylinder or in any other shape.
