Definitions

  • the present invention relates to a lock, particularly for a motor vehicle door.
  • this lock comprises:
  • the interference existing in a circumferential direction between these teeth reduces or preferably eliminates the possibility of the cylinder being rotated about the axis of the cavity of the bush, when the cylinder, as normally happens in break-ins, is forced axially inwards.
  • This interference therefore makes impossible to forcibly turn the cylinder, when acting from the outside, and thus to move the bolt operating member without authorization.
  • the lock to which the anti-torque security device of the present invention is fitted may also have other security devices, e.g. of the type in which, during attempted break-ins, a component is expelled in a radial direction in such a way as to break the continuity of the mechanism for transmitting movement from the proximal end of the cylinder to the bolt.
  • the level of security of the lock is greatly enhanced.
  • the anti-torque security device of the present invention can also be used as a single security device for a lock.
  • a lock particularly for a motor vehicle door, comprises (Figs. 1 and 2) a fixed bush 10 with a sleeve 11 attached to its distal end like an extension.
  • the bush 10 defines internally a cylindrical cavity 12 about whose axis 14 there rotates a cylinder 16 which is fitted with a restoring spring 18 and has a first weakened cross section 20 and a second weakened section 22 close to its proximal and distal ends respectively.
  • a slot 24 Around a circumferential section of the proximal portion of the bush 10 is a slot 24 able to house cylinder 16 retention means in the form of an inverted U-shaped spring 26.
  • the spring 26 prevents, in normal operation of the lock, translational movement of the cylinder 16 in an axial direction, once the cylinder has been inserted into the cavity 12.
  • the cylinder 16 is able to turn about the axis 14 when the appropriate key is inserted into the keyway.
  • the lock also includes an operating member 28 for operating a bolt (which in itself is conventional and not illustrated in the figures), which member 28 is controlled by a nose 30 that protrudes from the distal end of the cylinder 16 and passes through a central opening defined by an annular flange 32 located at the distal end of the bush 10.
  • the operating member 28 is also acted upon by springs 34 which react against a fixed surface of the sleeve 11.
  • teeth 36, 38 There protrude from the facing surfaces of the distal end of the cylinder 16 and of the annular flange 32 (Figs. 3 and 4) respective pluralities of circumferentially spaced teeth 36, 38.
  • the teeth 36, 38 of each plurality are staggered with respect to those 38, 36 of the other plurality - as will be described in more detail later - in such a way that movement of the cylinder 16 towards the distal end of the bush 10 causes, due to the interlocking of the teeth 36, 38, the formation of a continuous annular structure.
  • the nose 30 of the cylinder 16 has, at its distal end, an enlarged portion 40 which is followed by, when proceeding towards the proximal end, a portion 42 whose cross section is smaller than that of the enlarged portion 40 and therefore recessed compared with the latter.
  • the portion 40 is of polygonal, in particular rectangular section and is engaged in a slot 44 of complementary shape formed in a plate 46 integral with the operating member 28, so as to transmit a torque.
  • the distal portion 52 of the cylinder 16 still inside the bush 10 is therefore irreversibly locked inside it and cannot be returned to its original position in which it turns freely.
  • the portions of narrower cross section 42 of the nose 30 of the cylinder 16 could be circular so that no torque can be transmitted once it is in the slot 44 of the plate 46 integral with the operating member 28 following an attempted break-in.
  • This detail further enhances the locks' security because, even in the hypothetical event that the thief manages to turn the cylinder 16 by overcoming the resistance presented by the interlocking of the teeth 36, 38, the circular-section portion 42 of the nose 30 would rotate idly inside the slot 44 and could not therefore produce any movement in the operating member 28.
