Definitions

  • the invention relates to a device according to the preamble of claim 1.
  • the invention is based on such an arrangement and further develops it in an advantageous manner.
  • Such a closure device has become known from the German patent specification DE 3338604 C2 and the European patent application 0 140 028 based thereon.
  • an electromagnetic coupling device is effectively controlled, via which a rotary element on the outside of the door is connected to an element performing the lock actuation on the inside of the door.
  • the electromagnetic coupling device includes a swivel magnet, with the aid of which a mechanical coupling of a drive axis to an output axis is produced via a driver after reaching a specific swivel position.
  • the closure device has an additional holding magnet with a holding plate, which holds the swivel magnet for the duration of the current flow in this swiveled-out position, so that the swivel magnet, which operates with a higher current requirement and also with slippage with wear, can be switched off from the current flow.
  • This patented arrangement is ideal for the operation of multi-turn locks that require up to 2 full revolutions of the output axis to lock or unlock.
  • the described device is unnecessarily complex and voluminous.
  • the invention has for its object to provide a less complex and compact coupling device.
  • the object is achieved by the measures characterized in claim 1.
  • the coupling device is shorter and cheaper to manufacture, whereby the operation with regard to freedom from wear is completely sufficient for the planned application with quarter and half-turn locks.
  • the retractable design of the pins 24 described in claim 4 ensures that a force-free and non-destructive engagement of the driver 22 between the pins 24 of the drive element 5 is made possible in any position of the output axis 6 relative to the drive element 5.
  • the measures characterized in claim 5 achieve an embodiment of the coupling device with two offset axes, which enables opening-free external protection of the security-critical lock areas.
  • the measures characterized in claim 6 introduce a further gear wheel into the closure device, which allows the drive and driven axes to be arranged at a greater distance from one another and which also enables a reversal of direction between the two axes.
  • the measures characterized in claim 7 result in an arrangement which reliably protects against violent attempts at opening coming from the outside, since all security-critical areas of the lock are covered by a reinforced plate without 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.
  • This in turn is in constant engagement with a gear 5, which is freely rotatable about the output axis 6.
  • a disc 7 is rotatably connected, which consists of soft magnetic material and the represents part of an electromagnetic coupling device.
  • 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 coil 10 When the coil 10 is energized, the magnetic flux flows back from one leg of the magnet through the disk 7 to the other leg.
  • the disc 7 is thereby firmly attracted to the swivel magnet 9.
  • 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 disk 7 With the rotation of the axis 1, the disk 7 is rotated at the same time, so that when the swivel magnet 9 is excited, the swivel body 8 also rotates by a predetermined angle. We call the current flow required for this swinging-out process entrainment current.
  • the swivel body 8 is fixedly connected to the swivel magnet 9.
  • a swivel contact 3 is attached to the swivel body 8.
  • the swivel contact 3 touches the electrical contacts 14 or 15, as a result of which the current is switched from the higher driving current to the substantially lower holding current. Further details are shown in FIG. 3.
  • the holding current can be dimensioned so that the contact between the pivoting contact 3 and the contacts 14 or 15 is maintained as long as the current supply lasts.
  • the pivoted swivel body 8 is thus held in its swiveled-out position.
  • the swiveling body 8 is returned to its starting position by return springs 16, 17.
  • the swivel magnet 9 is fixed to the swivel body 8.
  • the swivel body 8 is rotatably mounted about the output axis 6, just like a running plate 20. With the rotation of the swiveling body 8, the running plate 20 is rotated by the latter.
  • 1c shows a sectional partial view of the swivel body 8, the running plate 20 and the housing 18.
  • Recesses 19 are incorporated into the housing 18, into which webs 21 protrude.
  • the webs 21 are firmly connected to the tread plate 20.
  • the run-up bevels resulting from the recesses 19 result in the running plate 20 being displaced in the axial direction when the running plate 20 rotates.
  • a driver 22, which is mounted in a milled recess in the output shaft 6, is pushed upwards against a spring 23 until it fully engages in pins 24 which are connected to the drive element 5. This creates a mechanical coupling between the drive axle 1 and the output axle 6, via which large forces can be transmitted.
  • the drive element 5 shows a detailed view of the drive element 5 with retractable pins 24 in a top view and in a sectional side view.
  • the driver 22 touches the pins 24.
  • the pins 24 are designed such that they can be sunk into the drive element 5 when the driver 22 is placed on it.
  • the driver 22 which is initially still stationary, engages in the gap between the pins 24.
  • the springs 25 bring the countersunk pins 24 back into the normal position, so that when the drive element 5 continues to rotate, the driver 22 is also rotated with the aid of the pins 24, as a result of which the output shaft 6 is also rotated.
  • a coupling of the output axis 6 to the drive axis 1 is then provided as long as the current flow continues.
  • Fig. 3 the simplest type of circuit for switching between driving current and holding current 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 arrangement. If voltage U is switched on to the arrangement and the arrangement is in its rest position, the contacts 14, 15 are open with respect to the swivel contact 3. In this state, the transistor TRI is open, i.e. the full driving current flows through the coil 10 of the swivel magnet 9.
  • the swivel magnet 9 with the swivel body 8 is then swung out through the disk 7 until the swivel contact 3 touches one of the contacts 14 or 15.
  • the transistor TRI is thus closed and only a small holding current flows through the coil 10 via the resistor R2. This holding current can be adjusted by correctly dimensioning R2 and the resistance of the coil 10 so that the contact remains closed as long as the current supply lasts.
  • the swivel body 8 has a purely two-point operation, which is also a permissible operating mode: if there is contact between swivel contact 3 and contact 14 or 15, the transistor TRI closes. The current in the coil 10 thus goes to zero via the freewheeling diode D1. As a result, the swivel body 8 moves back towards the zero position by spring force. This removes the contact from the contacts. The transistor TRI is opened again via the resistor R1, so that the higher driving current can flow again via the coil 10. As a result, the swivel body 8 is rotated again until the contacts are again touched, etc. This rapid switching on and off of the coil 10 continues as long as the arrangement is energized and the drive shaft 1 is rotated.
  • FIG. 4 the overall structure of a locking device with lock 44 and a coupling device 36 with offset axes is shown.
  • the outer protective and support plate 35 is screwed against the inside of the door.
  • the staggered arrangement of drive axis 1 and output axis 6 of the coupling device 36 makes it possible to protect the entire safety-critical area of the lock 44 by means of an armor plate 45 that does not open.
  • the drive axle 1 is extended towards the outside of the door with the aid of an intermediate axle 39.
  • the coupling device can be actuated with the aid of an outer rotary element 38 when the swivel magnet 9 is energized, which in turn is connected via the output axis 6 to the lock 44 and thus to the locking elements of the lock.
  • drive shaft 1 and thus also outer rotating element 38 can be freely rotated.
  • the output shaft 6 is accessible from the inside of the coupling device 36 on the inside of the door and thus permits the direct mechanical drive of the lock 44 by means of an inner actuating element 40 from the inside of the door.
