Definitions

  • the present invention relates to a protection device for a lock cylinder.
  • the present invention relates to the field of lock protection mechanisms, and more specifically the cylinders into which the key must be inserted in order to open the lock.
  • cylinders protrude from the lock or are otherwise exposed and are therefore susceptible to possible tampering, e.g. through the use of acid and/or tampering devices such as a drill.
  • a protection device according to the preamble of claim 1 is e.g. known from DE 296 19 390 U1 .
  • the technical task of the present invention is therefore to make available a protection device capable of overcoming the drawbacks resulting from the prior art.
  • the object of the present invention is therefore to provide a protection device that is capable of preventing tampering of the protection device itself.
  • a further object of the present invention is therefore to provide a protection device that can effectively protect the cylinder by preventing it from being exposed in a way that could facilitate tampering.
  • a protection device for a lock cylinder comprising a stator body comprising a coupling portion which may be coupled, during a configuration of use of the device, to a lock comprising a cylinder and a rotor body inserted into the stator body and rotatable about an axis of rotation of the rotor body, that is parallel, in use, to an insertion axis of a key of the cylinder which may be inserted into an insertion slot defined by the cylinder.
  • the rotor body is selectively rotatable, in use, between a closed position, wherein a locking wall of the rotor body completely occludes an inlet section of the insertion slot, and an open position, wherein an access window of the rotor body is coaxially arranged to the inlet section of the insertion slot.
  • the rotor body further comprises a mechanical locking device which may be switched between an unlocking configuration, wherein the rotor body is rotatable between the closed position and open position and vice versa, and a locking configuration, wherein the rotor body is locked at least in the closed position.
  • the device further comprises an actuating key of the rotor body, which may be inserted into an access portion of the mechanical locking device opposite, in use, to the locking wall, configured to switch the mechanical locking device from the locking configuration to the unlocking configuration and vice versa.
  • said body comprises at least one shaped guide defined in a perimeter portion of the stator body
  • said mechanical locking device comprises at least one locking box having a first end at least partially counter-shaped with respect to said shaped guide;said locking box being switchable, according to an insertion of said actuating key into said access portion, between the locking configuration wherein said first end is kept in contact by meshing with said shaped guide preventing the rotor body from rotating, and the unlocking configuration wherein said locking box is movable along a movement axis (M) perpendicular to said axis of rotation (A) of the rotor body so that said first end slides freely on said shaped guide allowing the rotor body to rotate.
  • M movement axis
  • A axis of rotation
  • the mechanical locking device comprises at least one set of pins and corresponding counter-pins, wherein each pin and counter-pin may be translated along a respective translation axis extending along a respective longitudinal extension axis of the pin, depending on an insertion of the actuating key into the access portion.

  • the locking box comprises a plurality of seats each adapted to define a translation axis of a respective pin and counter-pin, wherein in the first position the counter-pins are contained within respective seats defining the unlocking configuration, and the second position wherein the counter-pins are at least partially contained within the seat defining the locking configuration of the rotor body i.e. of the mechanical locking device.
  • the protective plate is movable sliding along a movement direction, perpendicular in use to the axis of rotation of the rotor body.
  • front is intended to mean an orientation of a user with respect to the device 1 (or vice versa) when it is installed or applied or mounted to the cylinder "C".
  • the open position means a position of the rotor body 3 in which an access window 3b of the rotor body 3 itself is arranged coaxially to the inlet section of the insertion slot.
  • the access window 3b is circular in shape or otherwise suitable to allow a total superposition which, in the open position, does not prevent the insertion of a key into the slot "F” or cylinder "C". In this way, the key can be inserted into the slot "F" when required.
  • the access window 3b is made in the form of a circular hole.
  • the rotor body 3 is rotatable between the open position and the closed position with a rotation about its axis of rotation "A" of at least 90°. Even more preferably, the rotor body 3 is rotatable between the open position and the closed position with a rotation about its axis of rotation "A" of at least 180°.
  • the rotor body 3 is rotatable between the open and closed position with a rotation of 180°.
  • the access window 3b and the locking wall 3a are located in opposite circular sectors of the rotor body 3.

  • the rotor body 3 further comprises a mechanical locking device 4 that can be switched between an unlocking and a locking configuration.
  • the mechanical locking device 4 is only equipped with mechanical components and has no electronic and/or magnetic components. Thus, barring heavy destructive tampering with the device 1, tools known for electrical or mechanical tampering with locks would be totally ineffective against the device 1 or the mechanical locking device 4.
  • the mechanical locking device 4 is a suitable mechanism to prevent rotation of the rotor body 3 when such rotation is not required.
  • the device 1 further comprises an actuating key 5 of the rotor body 3, which may be inserted into an access portion 6 of the mechanical locking device 4 opposite, in use, to the locking wall 3a.
  • the actuating key 5 is configured to switch the mechanical locking device 4 from the locking configuration to the unlocking configuration and vice versa.
  • the mechanical locking device 4 comprises a certain number of pins 4b and a corresponding number of counter-pins 4c.
  • the actuating key 5 is made to intercept the pins 4b in the access portion 6 and push the pins 4b against their respective counter-pins 4c during insertion and, once fully inserted, bring all the pins 4b and counter-pins 4c from the second position to the first position.
  • the locking box 7 has a first end 7a at least partially counter-shaped to the shaped guide 8.
  • the locking box 7 is switchable, depending on the insertion of the actuating key 5 into the access portion 6, between the first locking configuration and the unlocking configuration.

  • the first end 7a i.e. the locking box 7
  • the shaped guide 8 has an obtuse angle conformation and the first end 7a has a conformation suitable for meshing into the obtuse angle.
  • the locking box 7 is movable along a movement axis "M", perpendicular to the axis of rotation "A" of the rotor body 3, so that the first end 7a slides freely on the shaped guide 8 allowing rotation of the rotor body 3.
  • the first end 7a i.e. the locking box 7 maintains a reduced pressure contact with the shaped guide 8 and therefore, in the event of rotation of the rotor body 3, is able to make a minimal movement along the movement axis "M" which prevents it from meshing in the shaped guide 8 itself.
  • the locking box 7 is equipped with elastic return means (not shown) configured to keep the locking box 7 itself (i.e. the first end 7a) in contact with the shaped guide 8.
  • the return means exert a force on the locking box 7 to keep it in contact along the shaped guide 8 so that, in the locking configuration, the first end 7a remains meshed to the shaped guide 8, and in the unlocking configuration the first end 7a is free to slide in the shaped guide 8 preventing meshing of the first end 7a in the shaped guide when rotation of the rotor body 3 takes place.
  • the elastic return means are defined in a second end 7d of the locking box 7, opposite the first end 7a.
  • the mechanical locking device 4 comprises a pair of locking boxes 7, arranged laterally with respect to the locking wall 3a.
  • the locking boxes 7 are symmetrical to each other.

  • the counter-pins 4c are at least partially contained in their respective seats 7b and 7c, while the pins 4a are partially contained in the seats 7c and partially occupy the access portion 6.
  • the counter-pins 4c When the counter-pins 4c are in the second position ( Figure 4A ), they prevent movement of the locking box 7. In other words, the translation axis "T” and the movement axis "M” are perpendicular and incident to each other. Thus, the counter-pins 4c define blocks that prevent the movement of the locking box 7 along the movement axis "M", thus keeping the first end 7a meshed to the shaped guide 8.
  • the mechanical locking device 4 comprises at least two sets of pins and counter-pins 4a and a pair of locking boxes 7 opposed to each other with respect to the access portion 6 of the mechanical locking device 4.

  • the shape and profiles of the supporting elements 5b and slats 5c can be customised according to requirements, thus being able to take different shapes that can be coupled to the access portion 6 of the device and the pins 4b.
  • the slats 5c extend, when the actuating key 5 is inserted into the access portion 6, along an extension axis "L" of the slats 5c perpendicular to the extension axis (i.e. the translation axis "T") of the pins 4b.
  • Each slat 5c has a profile suitable for moving the respective set of pins and counter-pins 4a from the second position to the first position during an insertion of the actuating key 5 into the access portion 6.
  • each slat 5c has a particular thickness or shape suitable to intercept the respective pin 4b, during the insertion of the engagement portion 5a into the access portion 6, so as to move it back into the seat 7c in order to move the counter-pin 4c into the seat 7b. Therefore, the slats 5c allow for customisable profiles according to the user's needs.
  • the slats 5c are removably replaceable with additional slats 5c as a function of the second position taken by the set of pins and counter-pins 4a.
  • the slats 5c are removable (only when necessary) from the engagement portion 5a, e.g. by sliding between two supporting elements 5b (as for example depicted in Figure 5B ).

  • At least the grip portion 5d is made of plastic material.
  • the grip portion 5d comprises a meshing tooth 5e adapted to reversibly hook onto the access window 3b when the actuating key 5 is inserted into the access portion 6.

  • the step 10b has a conformation such that, during the rotation of the rotor body 3, it is inserted below the lower portion of the protective plate 10 or slides out of it so as to realise the sliding of the protective plate 10 along the guide 10a. Therefore, the step 10b has two curved or inclined ends defining a sliding ramp suitable for sliding the lower portion of the protective plate 10, which is thus able to be lifted and partially superimposed on the coupling seat 2b.
  • the device 1 is able to overcome the drawbacks of the prior art.
  • a user wishing to open the lock will use the actuating key 5 to switch the mechanical locking device 4 between the locking configuration and the unlocking configuration and then rotate the rotor body 3 between the closed position and the open position.
