Definitions

  • the present invention relates to a device for anchoring a protective boss for locks, particularly of the cylinder type.
  • the aim of the present invention is to provide a device which obviates the shortcomings of conventional devices and in particular can be installed even after fitting the external trim panel.
  • a device for anchoring a protective boss to a lock particularly of the cylinder type, characterized in that it comprises a plate-like element which is rigidly coupled to the lock and has an opening whose rim surrounds said cylinder and forms an undercut seat, said opening being adapted to receive said boss, means being provided with said boss which are suitable to engage in said seat and retain said boss anchored to said plate-like element, said boss being provided with holes for engaging screws for fixing said boss to said lock.
  • the reference numeral 1 generally designates a lock with a plurality of bolts 2 which can be actuated by means of a cylinder 3.
  • the lock 1 comprises a box-like body 4 which is protected, on the outer side, by a metal plate 5 which is in turn fixed to a sheet metal panel 5a which is installed for burglar-proofing in the door frame.
  • the metal plate 5 has, at a region that surrounds the seat 6 for the insertion of the cylinder 3, a quadrangular opening 7 against which an escutcheon 8, also made of metal, is fixed.
  • the escutcheon 8 is fixed by means of a peripheral weld which preferably does not exceed the thickness of the escutcheon 8.
  • the escutcheon 8 has a circular opening 9. Along the rim of the opening 9 there is a set of three recesses 10 which are angularly spaced by 120°, a corresponding number of lobes 11 being formed between such recesses.
  • the escutcheon 8 is rigidly coupled to the front face of the metal plate 5, the lobes 11 form, together with the wall of the box-like body 4, an undercut seat 12 whose thickness is equal to the thickness of the metal plate 5.
  • the opening 9 is meant to receive a boss 13 for protecting the cylinder 3.
  • the boss 13 comprises a cylinder made of a material which is particularly resistant to break-in stresses (drilling, traction) and is provided with a protected hole 14 for the insertion of the key that operates the lock.
  • the boss 13 is provided with two threaded holes for the engagement of screws 16 which are driven through the box-like body and by virtue of which the boss is fixed in order to neutralize undue rotational stresses.
  • the recesses 10 and the expansions 15 allow a bayonet coupling of the boss 13 by virtue of which the expansions 15, once inserted in the seat 12 through the recesses 10 and turned so as to engage the lobes 11 formed between the recesses 10, prevent, with the cooperation of the screws 16, the removal of the boss 13 from the lock protection position.
  • the innovative prerogative of the present invention is constituted by the fact that the boss 13 can be applied in the position for protecting the lock 1 after applying the door trim panel 17, as shown more clearly in Figure 2.
  • a ring 18 is arranged around the boss 13 and is meant to be fixed to the panel 17 in order to cover the boss insertion hole.
  • Figures 4, 5 and 6 are views of a solution in which the opening 9 of the escutcheon 8 is perfectly circular and instead of the recesses and lobes rigidly coupled to the boss, as in the previously described example, there is a ring 19 which is provided with an internal thread 20 and with a collar 21 which protrudes externally.
  • the collar 21 has a thickness which allows it to be accommodated in the seat 12, whereas the ring 19 has an outside diameter which is complementary to the diameter of the opening 9, so that it can be centered therein.
  • the boss 13 has, at one end, a thread 22 on which the ring 11 can be screwed by resorting to an adapted tool which acts in diametrically opposite notches 23 of the ring 19.
  • the rotation-preventing locking of the boss is achieved by the screws 16.
