Definitions

  • the present invention relates to a lock, particularly for safes, with burglar-proof locking bolt.
  • the aim of the present invention is therefore to provide a lock equipped with a locking bolt which, if forced, causes the engagement of a locking system which stops all axial movement of said locking bolt for retraction into the lock.
  • a lock with burglar-proof locking bolt particularly for safes, comprising a locking bolt slideable between a position in which it may engage a striker in the abutment jamb of a safe door and a position in which it retracts into a seat in the lock stile of a door, the bolt being loosely coupled to a lever which is articulated, at one end, to a movable element actuated by the lock and which is provided with a laterally protruding tooth at the opposite end, mutual contact planes being defined in said locking bolt and in said lever, said planes being inclined with respect to the sliding axis of the locking bolt so as to produce, when the locking bolt is externally forced to retract into said seat, deflection of said lever into a position in which said tooth abuts against the mouth of said seat so as to lock the locking bolt in the striker engagement position.
  • the reference numeral 1 indicates the lock stile of the door of a safe, proximate to which a known lock, of the key or combination type, is mounted; only the tang 2 of said lock, which actuates one or more locking bolts 3, is shown in the drawing.
  • the locking bolt 3 is constituted by a cylindrical barrel which is coupled to a lever 4 which is articulated to the tang 2 by means of a threaded bolt 5.
  • the reference numeral 6 designates a rod to which any additional locking bolts are connected; said rod is fixed to the tang 2 at right angles to the sliding direction of said tang.
  • the locking bolt 3 is guided in a seat 7 of the lock stile 1 so as to engage, when the safe is in closed position, a selvage 8 defined in the abutment jamb 9 of the door of said safe.
  • the free end of the lever 4 has a tooth 10, which protrudes laterally upward from the upper edge of the lever, and an oblique lower edge 11.
  • the lever 4 is inserted in a slot 12 which partially cuts the locking bolt 3 along a diametrical axial plane, forming an oblique bottom 13 which acts as abutment for the oblique edge 11 of the lever 4.
  • the locking bolt 3 and the lever 4 are mutually connected by means of a pin 14 which is diametrically inserted in the locking bolt 3 at right angles to the plane of the slot 12.
  • the pin 14 passes through a slot 15 of the lever 4 whose dimensions are such as to allow the lever 4 to perform axial strokes with respect to the locking bolt 3 and oscillate by an extent sufficient to allow the tooth 10 to leave the slot 12.
  • the locking bolt 3 is returned into the seat 7 after the lever 4 has covered an idle stroke portion defined by the play with which the pin 14 is inserted in the slot 15.
  • a substantial advantage of the invention is constituted by the fact that the forcing action applied to the locking bolt is not transmitted to the tang 2 and thus to the lock, which therefore suffer no damage at all and maintain their full efficiency. It should be noted that the locking bolt 3, by virtue of its structure, and the lever 4, by being protected by the locking bolt, also do not suffer appreciable deformations, so that the safe remains accessible even after the forcing attempt.
