Definitions

  • the invention relates to a safety lock with a pivoting stator of the type comprising a rotor swiveling in a stator by means of a notched key cooperating with locking members such as flakes or pairs of pistons returned by springs, said stator being pivotally mounted in a body and indexed elastically relative to this body, said rotor driving a lock control finger which, when the stator pivots with the rotor due to the introduction of a false key or a tool, is put out state of driving the lock due to the displacement of its axis of rotation made coaxial with the common axis of rotation rotor - stator or due to a radial translation of said finger.
  • Such a safety lock known from EP-0 151 081, has very high security against fraud attempts by rotation forcing and is also difficult to breach by probing the locking members. Indeed, any torque applied to the rotor causes it to rotate with the stator and the lock control finger is made inactive.
  • the drive finger is integral with a slide which is itself integral in rotation with the rotor and cooperating by cam effect with a recess in the stator and being returned by spring towards this recess .
  • This solution if it allows to build a short lock, has some faults, however. Indeed, the cooperation of the finger by cam effect with a recess in the stator can cause jamming, the angle of the recess and of the cooperating portion of the finger being critical.
  • the present invention aims to improve a lock of the type described in the introduction, in which said finger is integral with a movable slide in a diametrical groove of the rotor and resiliently biased outward, so as to avoid any risk of jamming and any premature wear of the lock.
  • the lock according to the invention is characterized in that the stator is provided with a radial opening which, in the rest position of the lock, extends said radial groove of the rotor and that a presser resiliently biased towards the inside the stator closes said opening in the rest position of the stator.
  • the presser clears the slide inside the rotor, at the start of rotation, and this slide is then held by the internal wall of the stator.
  • the stator pivots with the rotor and the edge of the opening lifts the presser so that, after rotation by a certain angle, the opening of the stator, which remains in the extension of the groove of the rotor, is no longer closed by the presser and the slide escapes through the opening, producing the radial translation of the finger it carries and which thus becomes coaxial with the rotor-stator assembly.
  • An important characteristic of the invention resides in that the presser cooperating with the opening of the stator forms the angular indexing of the lock, which allows a particularly simple, compact and economical construction.
  • the security lock shown in the accompanying drawings by way of example is constituted by a rotor 1 which can rotate in a coaxial stator 2, without lateral displacement, under the action of the opening key.
  • the stator 2 can rotate, without lateral displacement, inside a sleeve or body 3.
  • the rotor 1 is extended by a cylindrical plate 4 carrying a blind groove 5 in which a slide 6 carrying a drive finger 7 circulates which is perpendicular to it.
  • the slide 6 is hollow and contains a compression spring 8 which rests, on the one hand on the blind end of the groove 5 and on the other hand on the bottom of the slide 6 to project said slide 6 out of the groove 5.
  • a plate 9 is fixed by means of screws 10 on the open face of the plate 4 so as to hold the slide 6 inside the groove 5.
  • a cutout made in the plate 9 allows the movement of the drive finger 7 of the center on the periphery of the plateau 4.
  • the rear part of the stator 2 has a recess 12 completely surrounding the plate 4. It is milled along a plane parallel to the axis XX of the rotor so as to produce an opening 11 of the width of the slide 6. An opening 13 is made in the sleeve 3 for passing a presser 14 pushed by a leaf spring 15.
  • the presser 14 In the rest position, the presser 14 is applied to the milled part 11 of the stator 2, the spring 15 having a preponderance on the spring 8 of the slider 6 so that said slider 6 is kept entirely inside the groove 5.
  • a threshing cam 16 is applied internally against the closed end of the sleeve 3. It carries a stud 17 which engages in a hole with its diameter made in the rear face of the sleeve 3 on the axis X X. It also carries a extension which comes out through an opening 19 made in the sleeve 3.
  • the threshing cam 16 carries on its face opposite the plate 4 an opening 18 in which the finger moves.
  • a cap 20 covers the sleeve 3 on which it is fixed d '' in any way, to maintain the rotor - stator assembly inside the sleeve 3.
  • the control of the opening linkage is effected from the external extension of the threshing cam 16.
  • the device When the training finger 7 must rotate 360 degrees, for example to actuate a bolt, the device is produced according to the example of FIG. 3.
  • the threshing cam is replaced by a rotary part 22 rotating on the axis XX. It carries a groove 25 in which engages the drive finger 7, made from the axis XX over a length related to the amplitude of movement of the drive finger 7.
  • a plate 23 is fixed by screw 24 on the part 22 to prevent its lateral movement.
  • the plate 23 carries a finger 21 eccentric with respect to the axis X X.
  • the rotor 1 drives the stator 2 by the locking members such as pistons or flakes.
  • the stator 2 causes the lifting of the presser 14 and the release of the slider 6 pushed by the spring 8.
  • the finger 7, integral with the slider 6, moves towards the axis XX, its stroke being limited by the cutting of the plate 9 so that the clearance of the finger 7 being zero or insufficient, cannot cause either the threshing cam 16 or the part 22.
  • the rotor and the stator remain integral by the slider entered in the cutout of the stator so that, in the event of a false operation or fraud already indicated, it cannot have separation between rotor and stator until the completion of the complete turn.
  • the lock can operate normally with the compliant key, even from a position other than the initial position, the completion of the rotation of the rotor-stator assembly ensuring the return of the slide 6 inside the groove 5 by the action of the presser 14.
  • the presser 14 shown in Figure 1 can be made of synthetic material bonded to the sleeve 3 or molded therewith. It can be made of spring steel and fixed in any way on the sleeve 3.
  • the presser 14 can also be produced, according to FIG. 9, by means of a leaf spring 26 bearing on the rear face of the sleeve 3
  • the presser 14 is secured to a sliding plate 27 external to the sleeve 3 and returned to the low position by a spiral spring 28 acting on the stops 29 and 30 located on the sleeve and on the workpiece. sliding 27.
  • the presser may incidentally include a device aimed at indexing the position of the rotor more precisely in order to facilitate the removal of the key.
  • the presser 14 carries a slight recess 31 in which is housed the rounded end of the slide. The indexing thus produced of the slide leads to that of the rotor.
  • the milling of the stator can be carried out in two oblique planes, the shape of the presser being adapted to the cut thus produced, to allow it to be raised during the rotation of the stator. This arrangement allows faster movement of the slide.
  • the invention also applies to locks whose rotor is eccentric relative to the stator.
  • the cylindrical plate 4 rotates in the recess 12 of the stator 2.
  • the machining of the stator 2 around the recess 12 is eccentric so as to widen the bearing surface 32 of the presser 14 to ensure better immobilization of the stator.
