Definitions

  • the present invention relates to safety locks for dwelling doors and safes of the type comprising:
  • the object of the present invention is that of providing a lock of the above indicated type which has a safety degree much greater than that of the locks of the prior art.
  • the invention provides a safety lock for dwelling doors or safes having the above indicated features and characterised in that said safety lock is further provided with auxiliary locking means able to engage said at least one bolt or a member movable along with said bolt, in order to lock said at least one bolt when it is in its closed position, said lock further comprising:
  • Said transponder device may be of the so called "passive" type, i.e. it may be able to take the energy requested for transmitting its message from the coming signal. In this manner, it is not necessary to provide a supply battery within the key on which the transponder device is mounted, although of course this possibility is considered within the scope of the present invention.
  • Said electrically controlled locking means comprise for example an auxiliary bolt, driven by a solenoid or an electric motor, adapted to engage any one of the movable members of the lock to provide the additional locking of the latter in the closed condition.
  • said auxiliary bolt may be mounted within the frame of the door so as to cooperate with the main bolt of the lock in order to lock it in position once the latter is in the extended condition for engagement within a corresponding aperture formed within the frame of the door.
  • GB-A-2 204 353 discloses an electronically operable lock including means for transmitting pulses to a circuit in the key, this circuit rectifying the pulses received to provide a d.c. power supply for transmitting a key code back to the lock.
  • detection of presence of the authorized key merely causes actuation of an electomagnetic clutch which rotatably connects the key-operated cylinder to the lock mechanism.
  • reference numeral 1 diagrammatically and generally designates the structure of a door of a dwelling provided with a safety lock 2 having multiple bolts 3 which in the locked condition of the lock extend out of the structure of the lock and engage holes 4 formed in a fixed frame 5 anchored to the wall adjacent to the door 1.
  • the details of construction of the lock 2 are not shown in the annexed drawings, since the structure of the lock can be made in any known way and since this details do not fall, taken alone, within the scope of the present invention. Furthermore, the elimination of said details from the drawings renders the latter easier to understand.
  • the example shown refers to the case of a safety lock provided with a double-bit safety key 6 which is to be received within a key hole 7 formed within the housing of the lock to drive simultaneously the movement of the multiple bolts 3, and two vertical rods 8 whose free ends are for engaging seats formed respectively in the floor and in a bracket anchored to the wall when the lock is in the closed condition.
  • auxiliary bolts such as the bolt 9 shown in figure 2, or the bolts 10,11 shown in figure 3.
  • the bolt 9 is able to engage a corresponding seat 9a formed in one of the main bolts 3 to lock the latter in position in the closed condition of the lock.
  • bolt 10 is associated with a lever 12 connected to the inner mechanism of the lock, so as to prevent the lock to be opened when it is in the position shown in figure 3.
  • the bolt 11 is instead able to cooperate with a seat (not shown) formed in the upper rod 8, to lock the latter in position in the closed condition of the lock.
  • each auxiliary bolt 9,10,11 is driven by an actuating device, respectively designated by 9b, 10a, 11a, which may be comprised for example of a solenoid or an electric motor, for example a linear electric motor.
  • Said actuating devices are electrically connected by lines 13 to an electronic control unit 14 including a circuit board 15 connected by a line 16 to a supply battery 17 of a rechargeable type, which on its turn is connected to a supply socket 18.
  • the circuit board 15 is further connected by a line 19 to an electronic device 20 including a transmitter 21 and a receiver 22 which are for cooperation with a transponder device 23 which is associated with the handgrip portion of the safety lock 6.
  • the details of construction of the transmitter 21, the receiver 22 and the transponder device 23 are not shown herein since they may be promptly understood by the skilled men in the art.
  • the transponder device 23 is substantially a device able to receive a signal which is sent by the transmitter 21 as well as to reply with a signal which is received by the receiver 22.
  • the transponder device 23 is provided with a memory containing a pre-established code which renders the key 6 the only one authorised to open the lock.
  • the device 20 recognises the presence of the authorised key 6 and gives a corresponding signal to the electronic control unit 14 which thus enables the deactivation of the auxiliary bolts (9;10,11) when the lock is opened by the key.
  • the electronic control unit automatically provides for driving the auxiliary bolts in order to obtain the additional locking of the lock.
  • the device 20 can be mounted within the fixed frame of the door (figure 1) or on the housing of the lock 2 (figure 3).
  • the safety lock according to the invention provides a safety degree much greater than that afforded by the locks of the same type which have been made thus far.
  • the lock cannot be opened by a key which is identical to the authorised key but having no transponder device with the said pre-established code memorised therein.
  • the transponder device may be of the passive type, i.e. of the type able to take the energy requested to send the response signal from the received signal, but it can be also of the active type which requires the provision of a supply battery in the key.
