Definitions

  • the present invention relates to a locking device for a lock bolt which is adaptable to all locks, comprising at least one bolt ensuring the closing, for example of strong doors, armored doors, safes of any type, security furniture, strong cupboards and locks of the building.
  • the invention solves the above problem in a particularly appropriate manner by creating a space-saving device for preventing the opening of a lock by locking the bolt in the extended position in the event of an opening attempt, that this attempt to open takes place in particular by thermal means or by drilling.
  • the locking device for a lock bolt comprising at least one bolt, is characterized in that it comprises at least one locking plate for at least one bolt in the extended position and a holding element which controls bringing the locking plate into the locking position.
  • FIG. 1 there is shown schematically the door 1, pivoting along 2, of an armored system such as strong doors, armored doors, safes of any type, security furniture, strong cupboards, or the door of a system fitted with building locks.
  • an armored system such as strong doors, armored doors, safes of any type, security furniture, strong cupboards, or the door of a system fitted with building locks.
  • Door 1 in fig. 1 has a number of side bolts 3 shown in the drawing in the extended position in the wall framing the door 1, the lower bolts being assumed to enter directly into the ground or in the lower part of the door frame.
  • a locking plate 4 can slide in a corresponding groove in the lock housing and is crossed by the various bolts, while a locking system 5 allows to lock the locking plate 4 when an attempted break-in has brought the plate 4 into the locking position of the bolts 3.
  • a single locking plate 4 can be provided for the different bolts 3 corresponding to a given lock.
  • the various locking systems 5 of the locking plate 4, which can be respectively placed at variable locations on this plate, are preferably protected by a shield 6.
  • the lower part of door 1 does not have any shielding at the level of the blocking system.
  • FIGS. 2a and 2b there is shown a bolt 3 mounted on a support angle 10, the bolt 3 having a portion of smaller diameter 3a (fig. 2a) or simply a groove 3b (fig. 2b) delimiting, both shoulder 11.
  • the shoulder 11 of the bolt 3 is located at a distance from the end of the bolt 3 such that this shoulder slightly protrudes from the outside surface of the locking plate 4 when the bolt 3 is completely out of the lock, this locking plate 4 obviously having an orifice suitable for the passage of the bolt 3 and being mounted on a fixed support plate 12.
  • the locking plate 4 having for the passage of the bolt 3 a circular opening 13 extended by an oblong part 13a (fig. 3) or square 13b (fig. 5); the shape of this extension corresponds to that of the part of smaller diameter 3a (fig. 2a) or of the groove 3b (fig. 2b) of the bolt 3, the length of this groove 3b being also at least equal to the thickness of the locking plate 4.
  • the locking plate 4 is designed to be able to slide and the support plate has for this purpose guide pins 14 to which correspond the slots 15 provided in the locking plate 4.
  • a spring 20 is provided, one end of which is fixed at 21 to the support plate 12 and the other end of which is fixed at 22 to the locking plate 4.
  • a cable 23 is further connected at 24 to the locking plate 4 so that in the tensioned position of the cable 23, the latter is in the position of FIGS. 3 or 5 and lets the bolt 3 pass freely through the opening 13.
  • the locking plate 4 slides under the action of the spring 20 and then occupies the position of FIG. 7, that is to say a position such that the shoulder 11 of the bolt 3 comes into stop against the extension 13a (or 13b) of the opening 13 and prevents the bolt from entering inside the lock which is thus in the position for locking the bolt in the extended position.
  • the cable 23 by a reel return device 25, is placed on the surface of the system to be protected by following a predetermined path passing in particular through the compulsory passage points during an attack on the system by a burglar eventual.
  • the cable 23 is itself sensitive for example to heat (attack of the system by torch) or to cutting (attack of the system by drilling). Attacks on the system to be protected therefore result in a break in the wire 23 and a corresponding sliding maneuver of the locking plate 4 as indicated above.
  • an electromechanical device can be provided such that, if the current is interrupted by any attack by the system to be protected, the device triggers the operation of the locking plate 4, an electric wire then being placed in the sensitive places of the shielded system in the same way as the cable 23.
  • the operation of the locking plate 4 can be controlled by any other electromagnetic member incorporating an electrical or electronic means, either internal or external.
  • the locking plate It is also possible to control the operation of the locking plate by another mechanical type member, and for example by a lock or a mechanism controlled by a handle and which may itself be blocked by a lock.
  • the locking device according to the invention is no longer sensitive to any attack by the system to protect but can be controlled by a key or other security system.
  • the locking system 5 which is fixed to the support plate 12 comprises a finger 31 and a pressure spring 32 bearing against the screw 33 of the housing of the locking system 5.
  • the finger 31 abuts against a solid part of the locking plate 4.
  • the locking system 5 is then in the position shown in broken lines in Figs. 3 and 5.
  • the safety of the device is further increased by providing, as in FIG. 1, a particular shielding plate 6 at the level of the blocking system 5.
  • the blocking system 5 can be provided at any location on the locking plate 4 so as to be at a completely unspecified location.
