Definitions

  • the invention relates to a cylinder key of the type having a tubular insert and mobile piston.
  • Locks having tubular insert and mobile piston have been known for a long time.
  • a cylinder key of this kind is described for example in FR 2,604,206 .
  • This key comprises especially a tubular insert, which is open at its insertion end, and which contains a mobile piston stressed by a spring.
  • this piston has its course limited by a stop in the key receptacle of the cylinder and is pushed back up to a retraction shoulder of the insert, such that the insert necessarily lies in a determined position inside the key receptacle.
  • the insert is fitted with projections intended to control locking and unlocking of the mobile locking bodies of the cylinder stator.
  • the aim of the invention is to provide a key having a tubular insert and mobile piston, as well as a cylinder, which have additional coding possibilities.
  • Another aim of the invention is to provide a key and a cylinder which limit a little more lock-picking possibilities.
  • Yet another aim of the invention is to provide a key and a cylinder which are reasonable to machine and assemble.
  • a cylinder key of the type comprising:
  • the cooperation means enable the possibility of additional coding by making determination of the effective length of the key less obvious.
  • Another advantage offered by such a key is the possibility of increasing the number of combinations of coding means to ensure security of the cylinder-key mechanism while avoiding rendering the machining and assembly of the pieces more complex,
  • Another advantage is that it is more difficult to lock-pick the cylinder, especially because of unusual coding means.
  • the invention also provides a cylinder comprising:
  • the sliding pushing button enables the possibility of additional coding by making determination of the effective length of the key less obvious.
  • the invention provides a locking assembly comprising a key and a cylinder such as described above.
  • a locking assembly comprising a key 2 and a cylinder 1 is described below in reference to Figures 1a, 1b , 2, 2a , 2b and 3 .
  • the key 2 comprises:
  • the tubular insert 22 can be cylindrical in shape and extend along an axis I-I such as shown in Figure 1 .
  • the tubular insert 22 is provided with one or more projections 23 for controlling locking elements 15a of the cylinder into unlocking and locking, as further described in detail below. These projections 23 extend axially and radially over a certain length of the tubular insert 22 and are distributed over a periphery of the tubular insert 22.
  • the inner housing of the tubular insert 22 houses a piston 24 which is mobile in translation in said insert 22 and which is supported against a spring 25 arranged in the bottom of the inner housing of the tubular insert 22, this spring 25 exerting axial effort against this piston 24 tending to push it back towards the free end of the tubular insert 22.
  • the tubular insert 22 comprises one or more inner grooves 26 of determined position(s), form(s) and dimension(s) (see Figure 2a ).
  • a groove 26 extends along the tubular insert 22 parallel to the axis I-I of the tubular insert 22 and terminates at the free end of the tubular insert 22.
  • the groove 26 passes through for example the entire tubular thickness of the tubular insert 22 defining a slotted recess at the free end.
  • these grooves 26 can have different longitudinal dimensions relative to the tubular insert 22.
  • the mobile piston 24 can also comprise a protrusion 27 which extends radially relative to said piston and which is guided in a longitudinal slot 28 provided in the tubular insert 22, in projecting out of the tubular insert 22.
  • This protrusion 27, intended to cooperate with locking means of the cylinder, has a form defining:
  • the cylinder 1 with which the key 2 cooperates is described below.
  • the cylinder 1 comprises a tubular cylindrical longitudinal stator 10 comprising:
  • the cylinder 1 also comprises a longitudinal rotating rotor 11 adapted to control at least one locking tumbler of a door, a window, a vault or the like.
  • This longitudinal rotor 11 comprises in particular:
  • the longitudinal rotor 11 is housed in the housing 10'.
  • the key receptacle 13 and the inlet opening 12 are arranged to enable insertion of the tubular insert 22 along the axis I-I.
  • the sliding pushing button 14a comprises at least one second radial projection 14c cooperating with an inner groove 26 terminating at the free end of the insert 22, the groove 26, such as the projection 14c having an angular position, a form and a size at least in width such that the groove 26 can receive the second projection 14c during introduction of the tubular insert 22 into the cylinder 1.
  • the longitudinal average plane of the second projection 14c can substantially pass through the axis of the sliding pushing button 14a.
  • the first and second projections 14c of the sliding pushing button 14a form a single projection 14c.
  • the single projection 14c formed by the first and second projections 14c can have a Y-shaped cross-section.
  • a pump 17a anti-picking interposed between the longitudinal stator 10 and the longitudinal rotor 11, arranged behind the sliding pushing button 14a so as not to be accessible by a hook inserted in the key receptacle 13, and actuated by the latter in translation can be provided in the cylinder 1.
  • a spring 17b biases the anti-picking pump 17a towards its initial position.
  • the anti-picking pump 17a ensures additional security to the cylinder-key mechanism.
  • a secondary locking piston 16a mounted to radially slide can be interposed between the longitudinal rotor 11 and the longitudinal stator 10.
  • a spring 16b biases the piston 16a towards its interposition position.
  • the sliding pushing button 14a is connected to a driver 19 such that if it is displaced in translation, the driver 19 undergoes the same translation. Once this driver 19 is correctly positioned, it enables rotation of the rotor 11.
  • the key 2 has a mobile piston 24 inside its tubular insert 22, and that the free end of its tubular insert 22 has at least one groove 26 which engages on the projection 14c of the sliding pushing button 14a during insertion of the key 2, three lengths of insertion of the insert 22 can be defined.
  • a first length corresponds to the inserted length of the tubular insert 22 until the tubular insert 22 only contacts the sliding pushing button 14a.
  • a second length corresponds to the inserted length of the tubular insert 22 necessary for the sliding pushing button 14a to start being displaced in the same direction as the direction of insertion of the key 2.
  • the second length is the sum of the first length and of an additional length.
  • a third length corresponds to the inserted length of the tubular insert 22 necessary for the sliding pushing button 14a to sufficiently shift the driver 19 and correctly aligned the unlocking elements 15a relative to the followers 18 to free up rotation of the longitudinal rotor 11.
  • the key 2 further enables several codings:
  • the additional length is obtained:
  • the widths of the groove 26 and of the second projection 14c must therefore correspond, that is, they must be dimensioned so as to engage in each other.
  • the protrusion 27 constitutes other coding means of the cylinder-key mechanism.
  • Figure 3 shows the cylinder 1 prior to introduction of the tubular insert 22.
  • the initial mobile locking elements 15a shown here in the form of pumps for the sake of illustration, contact for example tangentially, the longitudinal stator 10 via the follower 18 fixed to the longitudinal stator 10.
  • a secondary locking piston 16a mounted to radially slide is interposed between the longitudinal rotor 11 and the longitudinal stator 10 and an anti-picking pump 17a is interposed between the longitudinal rotor 11 and the longitudinal stator 10, here via the follower 18.
  • Figure 4 corresponds to insertion of the lock 2 via the inlet opening 12 in the key receptacle 13, until the mobile piston 24 contacts with the sliding pushing button 14a, that is, the key has been introduced up to the first length of insertion.
  • the sliding pushing button 14a moves the mobile piston 24 in the direction opposite the direction of insertion of the key 2.
  • the second projection 14c of the sliding pushing button 14a is inserted in the groove 26.
  • Figure 5 corresponds to the configuration in which the key has been introduced up to the additional length. Either the mobile piston 24 comes into contact with the stop surface 29 provided inside the insert 22, or the second projection 14c engages the groove 26, or the end of the tubular insert 22 comes into contact with a surface 14e not in the projection of the sliding pushing button 14a.
  • the tubular insert 22 translates the sliding pushing button 14a in the same direction as the direction of insertion of the key 2 into the cylinder 1.
  • the sliding pushing button 14a in its displacement, axially drives a driver 19 to free up rotation of the longitudinal rotor 11 as known to the person skilled in the art.
  • Figure 6 illustrates the moment when the radial protrusion 27 of the mobile piston 24 contacts the secondary locking piston 16a mounted to radially slide between the longitudinal rotor 11 and the longitudinal stator 10 of the cylinder 1.
  • the protrusion 27 comprises a surface adapted to allow the secondary locking piston 16a to slide under the protrusion 27.
  • the protrusion 27 has a ramp inclined relative to the axis of the piston, the ramp then exerts pressure on the secondary locking piston 16a, shifting it radially to the axis I-I, when the key 2 is further introduced into the key receptacle 13.
  • Figure 7 corresponds to the moment when the sliding pushing button 14a contacts the anti-picking pump 17a, via a surface 14d opposite the projections 14c.
  • the sliding pushing button 14a drives the anti-picking pump 17a in translation.
  • the locking elements 15a have been positioned by the projections 23 of the tubular insert 22 of the key 2 so as to free up rotation of the longitudinal rotor 11, that is, so as to no longer be interposed between the longitudinal rotor 11 and the longitudinal stator 10 where the followers 18 is.
  • the locking elements 15a, the locking piston 16a, the anti-picking pump 17a and the sliding pushing button 14a are biased towards their initial position, that is, those of the initial configuration (see Figure 3 ), by the springs, respectively 15b, 16b, 17b, and 14b.
