Definitions

  • the present invention relates to a device for combination locks.
  • the rotatable dial used for input of the combination must be rotated a number of revolutions, and the required number of revolutions is related to the number of combination wheels included in the combination lock, e.g. for a lock having three combination wheels, the dial must be rotated at least three revolutions to secure completion of a locking operation. It is well known that many users only slightly turn said dial, whereby the lock appears to be locked. However, in such a case, it is extremely easy for an unauthorized person to operate the dial and thereby cause the combination wheel within the lock that has been slightly moved to return to the correct position for opening, and to gain access to the location protected by the combination lock.
  • Combination locks do not normally include a device indicating whether or not the dial has been rotated a sufficient number of revolutions in correct rotary direction to secure a complete locking operation, and it is thus assumed that a user by its own initiative will rotate the dial in the correct direction, and with a sufficient number of revolutions.
  • GB-A-2 093 520 discloses a monitoring system for monitoring and electronical indication of the operative condition of a combination lock. It is based on having one side surface of the combination wheels included in a combination lock with areas that are alternately light reflecting and light non-­reflecting. An optical detector is arranged adjacent to said side surface, including a light source and a light sensitive element. A part of the lock bolt mechanism is also correspon­dingly arranged with areas of light reflecting and non-­reflecting type, and a second optical detector is arranged adjacent hereto. This makes it possible, in combination with an associated electronical circuit, to monitor the rotation of a combination wheel as well as the position of a part related to the lock bolt mechanism. However, this monitoring system is an integrated part of the combination lock, and it is thus no solution for existing installations of combination locks.
  • the object of the present invention is to disclose a device adapted to monitor that a complete locking operation is carried out with regard to existing installations of combina­tion locks for safes and similar, which can be installed in a simple and rapid fashion, without demounting or modifying existing lock mechanism.
  • the device is arranged to monitor that a combination lock is completely locked, and it is mainly characterised in that it includes a means arranged adjacent to the dial whereby input of the combination is performed, arranged to monitor the rotary direction of the dial, and in combination with an associated electronical circuit initiate counting of the revolutions of the dial when same is rotated in a direction arranged to release the combination wheels of the lock, and to perform counting for a predetermined number of revolutions when the rotary direction is maintained unchanged.
  • Fig. 1 is intended to serve as an example of how a device according to the present invention, as a complete unit denominated A, can be located in relation to the dial 1 whereby input of the combination of a combination lock is performed.
  • the device A is attached to the same outside surface of a safe door or similar as the dial 1, and adjacent to the dial 1.
  • the device according to the present invention can also be arranged with only a smaller part B of the device attached adjacent to the dial 1, electrically connected by means of a wired circuit C to a second part D of the device, the second part D including associated electronical circuits and electric power supply, whereas the first part B includes means for monitoring the rotary movements of the dial 1.
  • a permanent magnet 2 has been arranged located attached within a surrounding hole, and adjacent to the dial 1 are two tongue elements or Reed relays 3, 3′ arranged, which are operated successively in relation to each other when the dial 1 is rotated in any desired rotary direction.
  • the present rotary direction can thus be decided, and counting of the number of rotary revolutions can also be initiated and carried out when rotation is performed in the rotary direction that results in locking of the combination lock, i.e. releases the combination wheels included in the combination lock.
  • FIG. 4 A further example of how such monitoring can be carried out is shown in Fig. 4.
  • the tongue elements 3, 3′ have been replaced by two coils 4, 4′, which, when the dial is rotated, cause an electric current pulse, whereby the sequence of order of generated current pulses on one hand facilitate monitoring of the rotary direction for the dial, and on the other hand also facilitate initation and counting of each other successively following rotary revolutions in a pre-­determined rotary direction.
  • FIG. 5 A modification of the embodiment of Fig. 4 is shown in Fig. 5.
  • two permanent magnets 2, 2′ are arranged in successively following positions in relation to each other by the peripheral portion of the dial, and with the north and south pole of the permanent magnets 2, 2′ arranged in an opposed relationship to each other.
  • Only one coil 4 is now required to monitor the rotary direction, and the number of revolutions, since the direction of the current for two each other successively following current pulses from the coil 4 indicate the rotary direction of the dial 1.
  • a counting circuit can be initiated, which counts the number of rotary revolutions while the pulse sequence is maintained in the same order.
  • Fig. 5 can obviously be further modified, e.g. by arranging the two permanent magnets 2, 2′ to influence one or a number of magnetically operable switch means, which make it possible to receive an output signal representative for the order in which the permanent magnets 2, 2′ pass during the rotary movement of the dial 1, thus indicating rotary direction and facilitating count of each other successively following revolutions in a certain and predetermined rotary direction.
  • FIG. 6 A further alternative embodiment is shown in Fig. 6.
  • a visually readable marking 5 has now been applied by an outer portion of the dial 1, e.g. a tape attachable against the dial and having bar code markings of previously known type.
  • Such bar code markings include lines spaced from each other, having a varied width, extending in a transverse relationship to the rotary direction.
  • Reading of the rotary direction can obviously also be carried out by means of mechanical sensing, and an example of this is shown in Fig. 7.
  • a wheel 7 is arranged in contact with a peripheral portion of the dial 1, and its rotary direction, and the number of revolutions, make it possible to monitor in which direction the dial 1 is rotated, and to count the number of successively following revolutions in a pre­determined rotary direction.
  • the method by which the rotation of the wheel 7 is sensed with regard to rotary direction/re­volutions may be varied in a number of ways using known prior art, e.g. by arranging the wheel 7 to operate an electrical switching means for each completed revolution but only provided that rotation is performed in a certain direction. If rotation is performed in the opposed direction, a second switching means can be operated, which will reset a counter circuit connected to the first switching means.
  • the above described operations (a - c) are initiated only when a safe door or similar, intended to be locked, has been moved to a closed position. This can be accomplished by a magnetic switch or other type of switching means, which is influenced when a closing operation is performed, or when the lock bolts are moved to an interconnecting position.
  • a voltage feed is applied to a timer circuit.
  • the dial 1 of the combination lock not be rotated a predetermined number of revolutions, for example four, in one direction only and within the time period monitored by the timer circuit, e.g. 10 seconds, the counter is reset, and the dial must again be rotated four revolutions. Should the counter circuit not be influenced during the time period monitored, an acoustic signal source is connected, which will indicate to the user that a correct locking sequence has not been performed.
  • the device may also advantageously be arranged with a terminal for connection to an alarm system. This would result in the advantage, that when switching on the alarm system, it is checked whether or not the combination lock has been locked with the correct number of revolutions. Furthermore, when the alarm system is switched on, the dial of the combination lock can not be manipulated, without causing alarm transmission.
  • the device can obviously further include one or a number of optical signalling sources, e.g. of LED type, intended to indicate status. Accordingly, for example, a green LED may be lit when the lock is completely locked, whereas a red indicates when the lock is in an open position, or only partly locked. Obviously, for example, the latter may be arranged to be connected when the aforementioned timer circuit is connected, and to be switched off or replaced by another optical signalling source when a complete locking operation has been performed.
  • one or a number of optical signalling sources e.g. of LED type, intended to indicate status. Accordingly, for example, a green LED may be lit when the lock is completely locked, whereas a red indicates when the lock is in an open position, or only partly locked.
  • the latter may be arranged to be connected when the aforementioned timer circuit is connected, and to be switched off or replaced by another optical signalling source when a complete locking operation has been performed.
  • the device according to the present invention is advan­tageously arranged to be fed from one or a number of elec­trical batteries enclosed within the device, whereby voltage feed from a mains voltage source is not required.
  • a suitable battery voltage source can be stated a 9 volt battery
  • the device may also advantageously include a voltage monitoring circuit, arranged to acoustically or optically indicate when the battery voltage has been reduced below a predetermined limit, and when a change of battery thus should be performed.
