Displacement of the shield S takes place between a permission position for passage of the key or other, in which said passage port is clear, and at least one obstruction position in which said passage port is at least partly obstructed by said shield S.
  • the shield is disposed inside the frame, internally of box 2 for example.
  • shield S is adapted to generate a growing obstruction of the passage port of the key depending on the shield position; for instance, shield S at least has a substantially inclined profile S'.
  • the shield is disposed parallel to the safety plates 4 and preferably is formed with an anti-manipulation plate 22.
  • the anti-manipulation plate 22 is disposed parallel to the safety plates 4. As shown in Fig. 1, the anti- manipulation plate 22 is disposed in an intermediate position relative to the pack of safety plates 4; alternatively, the anti-manipulation plate can be disposed at any position relative to the pack of safety plates 4.
  • Slide slots of the anti-manipulation plate 22 have been identified by reference numeral 5; they are adapted to respectively receive a pin 6 associated with box 2 for guiding the movement of the anti-manipulation 22 plate inside box 2.
  • the anti-manipulation plate 22 comprises a window 23 having an indented edge.
  • the window has an inclined profile 24 defining at least one apex 25.
  • two opposite inclined profiles define an apex 25.
  • the position of apex 25 corresponds to overcoming of a groove 9 with reference to the opening movement of the safety pin 13 relative to the safety plates 4.
  • the anti-manipulation plate 22 shown in the figure comprises two apices 25 corresponding to overcoming of the first and third grooves 9 respectively, with reference to the opening movement of the safety pin 13 relative to the safety plates 4.
  • Denoted at 26 is a displacement wing, in particular a lifting-up wing, extending transversely of the planar extension of the anti-manipulation plate 22.
  • a displacement wing in particular a lifting-up wing, extending transversely of the planar extension of the anti-manipulation plate 22.
  • two displacement wings 26 are provided which extend away from the plane of the anti-manipulation plate 14 towards opposite directions.
  • the displacement wing 26 extends in such a manner that it is disposed transversely of at least one safety plate 4 parallel to the anti-manipulation plate 22.
  • displacement wing 26 is for example disposed at an upper edge of the anti-manipulation plate 22.
  • the safety plate 4 drags along the anti-manipulation plate 22.
  • the displacement wings 26 define constraint means between the anti-manipulation plate 22 (shield S) and at least one safety plate. Said constraint means is operative when passing to the enabling position of the safety plate.
  • At least one first displacement (lifting) of the anti-manipulation plate 22 and correspondingly of shield S is therefore generated by displacement (lifting) of at least one safety place 4 instead of being generated by the key that, at the anti-manipulation plate 22, preferably has maximum piercing.
  • the inclined profile 25 is adapted to interact with the bolt member 12, in particular the safety pin 13, to make the anti-manipulation plate 22 further rise, for instance until it is disposed so that its apex 26 rests on the safety pin 13, on passage between the second position and first position of the bolt member 12.
  • the inclined profile 25 terminates at a support position of the anti-manipulation plate 22 on the bolt member 12, at apex 26 for example.
  • the inclined profile 25 defines a shaped profile adapted to (preferably further) lift the anti-manipulation plate to a further obstruction position, as clarified when describing operation of the lock according to the present invention.
  • the shaped profile 25 and safety pin 13 form translation cam means operating between the anti- manipulation plate 22 and the bolt member 12.
  • the anti- manipulation plate 22 comprises a passage slot 27 for the key.
  • the passage slot 27 is delimited by a closed profile P.
  • the passage slot 27 comprises a first or upper portion substantially closely following or comprising the area of the key passage port (in a plane parallel to the safety plates) and a second or lower portion of varying width along the height of the anti- manipulation plate.
  • the term "height” it is intended the vertical size of the anti-manipulation plate with reference to Fig. 1 or 2; by width it is intended the horizontal size of the anti-manipulation plate with reference to Fig. 1 or 2, in the plane of the plate itself .
  • the width of the lower portion of slot 27 increases from a lower edge of the lower portion, in which it is smaller than the width of the passage port, until opening into the upper portion where it is the same as or greater than the width of the passage port.
  • the lower portion of slot 27 has at least one size smaller than the corresponding size of the passage port in the plane of the anti- manipulation plate.
  • the anti-manipulation plate 22 comprises a passage opening for the key (having an open or closed profile) provided with a first portion substantially closely following or comprising the area of the key passage port and a second portion confining the shield.
  • the anti- manipulation plate 22 is usually disposed to a height in which the upper portion of slot 27 is aligned with opening 7 and is extended enough to closely follow or comprise such a passage port.

  • the anti-manipulation plate 22 (or generally the shield S) is raised by the manipulation instrument and the safety plates 4, thus partly obstructing the key passage port. Possibly partial sliding of the bolt member 12 according to arrow A causes further raising of the anti-manipulation plate 22 and further obstruction of the passage port.
  • shield S can be mounted inside the safety lock in such a manner that it is shiftable even due to movement of the bolt member alone from the closed position to the open position causing the translation cam means to intervene.
  • the constraint means between the anti-manipulation plate and the safety plates can be different, and lower wings on the safety plates adjacent to the anti-manipulation plate can be for example provided.
