Definitions

  • This invention relates to an electromechanical locking unit in accordance with the preamble of claim 1, to a switch arrangement therefor and to a lock system.
  • an electromechanical locking unit it is possible to use either the mains supply or a battery or other separate power source suitable for the purpose, for instance an accumulator, which can be located a distance away from the actual locking site.
  • the use of mains power or a power source located at a distance away from the locking site requires the provision of wiring.
  • a battery can, naturally, be used as an extra power source in the event of a power failure.
  • a battery can also be used as the main power source if it is desired to use the locking unit as a separate, so-called "stand alone" unit independent of the mains supply and thus also free from any mains wiring.
  • the battery is located in the locking unit itself or in the vicinity of the locking unit.
  • Different mechanical connecting arrangements are known, by means of which the insertion of the key of a lock into the lock simultaneously causes, through its movement, a power circuit to be switched on. This kind of known mechanical switch requires space and since it has moveable parts which are prone to wear is generally unsatisfactory.
  • An aim of the present invention is to provide a locking unit with a novel current switch arrangement, which is constructionally simple and reliable in use and from which the drawbacks of the known art mentioned above are essentially eliminated.
  • an electromechanical locking unit as claimed in the ensuing claim 1.
  • the locking unit With such a locking unit saving of the life of the battery is achieved so that the current is switched on only when the key is inserted into the lock.
  • the locking unit is, however, relatively simple in construction and is operationally reliable, since it does not include movable parts.
  • the reed switch and the permanent magnet means are mutually positioned so that the reed switch normally remains in an open position in the magnetic field provided by the permanent magnet means.
  • the permanent magnet means comprises two permanent magnet elements located on different sides of the key hole and jointly providing the magnetic field required for operation of the reed switch.
  • the reed switch and the permanent magnet means may be located inside a protection element of the locking unit which protects the cylinder lock from outside, and in particular which provides protection around the key hole ahead of the cylinder lock mechanism in the insertion direction of the key.
  • the piece of ferromagnetic material conveniently comprises a sleeve-like piece of iron or the like fastened to the key shank.
  • the piece is located at the lower part of the key shank associated with the key bow, whereby the piece affects the magnetic field activating the reed switch when the key is inserted right down to the bottom of the key channel of the cylinder lock.
  • the key bow can with advantage be case-like so that it also encloses the piece of ferromagnetic material of iron or the like.
  • the locking unit includes a pulse controlled switch which is arranged to be closed by the reed switch under the influence of the key for connecting the electronic control unit to the power source. Hence, only the generation of a minor, initial pulse is required to activate the connection.
  • the locking unit may also include further means, for example a micro circuit, for opening the pulse controlled switch after finishing the operation of the locking unit. Such an arrangement preserves the life of the battery and keeps the switch arrangement constructionally as uncomplicated as possible.
  • the advantages of the invention can best be met when the power source of the locking unit is a replaceable battery.
  • the drawings show a cylinder lock 1 of a locking unit which is operated in a known manner by the shank 2a of a key 2.
  • the cylinder lock 1 cooperates with a lock housing 3 mounted in a door or the like for moving a lock bolt 3a.
  • the locking unit also includes electrically operated blocking means 4 controlled by an electronic unit 5 and which functions independently of the locking mechanism of the cylinder lock 1.
  • the blocking means 4 has a locked position which prevents force being transmitted from the key 2, via the cylinder lock 1, to the lock bolt 3a, and a releasing position.
  • the operation of the blocking means 4 is dependent on an electronic code of the key which code is memorized in a memory circuit 2b located in the key, in practice more specifically in the key bow.
  • a current switch means 6 connects circuits in the electronic unit 5 to a battery 17.
  • the electronic code associated with the key is supplied to the unit 5 and/or is read in a known manner such as, for instance, through induction.
  • antenna means 7 are used to read the code sent from the key. If the correct code is read, the electronic unit 5 causes the blocking means 4 to be moved into its releasing position, which allows the lock bolt 3a to be removed by operation of the key 2.
  • the locking unit may also be provided, in a known manner, with a protective fitting 8 for protecting the lock parts 1, 4, 6 and 7 against attempted forcing from outside.
  • the battery 17 may, for instance, be located in the electronic unit 5 itself or in the immediate vicinity of the electronic unit.
  • the current switch means 6 provides current to the electronic unit 5 only when the key 2 is inserted into the lock 1.
  • the current switch means 6 comprises a so called reed switch 10 and two permanent magnets lla and llb.
  • the reed switch 10 is located in the magnetic field provided by the magnets and is in a normally open condition.
  • a piece 12 of ferromagnetic material e.g.
  • a sleeve of ferromagnetic material located on the shank of the key 2 causes a change in the magnetic field.
  • the reed switch 10 provides a control voltage pulse Ubat in a circuit 13, which closes a pulse-controlled switch 14 under the influence of a capacitor 15 included in the circuit 13.
  • the electronic unit 5 is connected to the battery 17.
  • a micro circuit 16 included in the electronic unit 5 opens the switch 14 to save battery life.
  • the reed switch 10 and the permanent magnets lla and 11b are with advantage arranged in a separate switch unit 9 located inside the protection fitting 8.
  • the switch means could also be located inside the cylinder lock, in which case the piece 12 of ferromagnetic material would be located correspondingly closer to the free end of the key shank 2a.
  • the number of permanent magnets provided can be varied. It is only necessary that the reed switch remains open when the key is not in the lock and is closed when the key is inserted into the lock to influence the magnetic field created by the permanent magnets.
  • the piece 12 of ferromagnetic material is with advantage designed so that on the one hand it provides a change in the magnetic field, detected by the reed switch 10, when the key is inserted into the lock and on the other hand can easily be supported and fastened to the key.
