Definitions

  • CH-A-340 152 shows a lock of this kind intended to ensure high security.
  • the introduction of a compliant key correctly erases the selection members and activates the rotor.
  • the lock comprises secondary selection members urged by balls placed in housings forming ramps, at the rotor / stator separation.
  • the secondary selection members which are pushed radially inward, can enter, by their ends, in corresponding imprints of the key, at the start of the rotation of the rotor.
  • the object of the invention is, above all to provide a lock in which the rotational connection between the key and the rotor is established by the longitudinal insertion movement of the key, so that a non-conforming key can turn madly in the key housing.
  • the lock be of simple construction with as few parts as possible.
  • a lock of the kind defined above is characterized in that the rotor is slidably mounted in the stator and comprises a sleeve-shaped part engaged in an annular housing of the stator and that elastic means are provided between the rotor and the stator to cause their relative sliding, the selection members being arranged to prevent such sliding until they are correctly erased, the retractable connection means being provided to establish a connection in rotation between the key and the rotor and being actuated by the sliding of the rotor relative to the stator so that a non-conforming key can turn mad in the housing, the aforesaid connecting means being arranged to bring back the rotor in a rest position, against the elastic means, when removing a conforming key.
  • the retractable connection means between the key and the rotor comprise, on the side of the rotor, a radially movable pin projecting outwardly in a recess in the stator comprising a ramp capable of pushing the pin radially inward during the sliding of the rotor relative to the stator, while the inner radial end of the aforesaid pin is adapted to project into a bore of the rotor, extending the housing of the stator, so as to enter a recess provided at the end of the key, this pin being biased radially outwards by a spring.
  • the selection members include flakes whose mean plane is orthogonal to the direction of the axis of the stator housing, these flakes being arranged in chambers of the stator parallel, one behind the other, and having two ends of greater width and a narrower intermediate part, each flake passing through an opening provided in the wall of the rotor sleeve, each of these rotor openings comprising two parts of different angular extent, axially offset, communicating through a narrower passage, l 'assembly being such that, in the rest position, a wide end of a straw is engaged in the part of reduced angular extent of the opening of the rotor and thus blocks in rotation the rotor relative to the stator, while when the flakes are correctly erased, the narrow part of each flake is opposite the passage of the corresponding opening, c e which allows the sliding of the rotor relative to the stator, the aforementioned narrow part of the flake then arriving in the part of greater angular extent of the opening, which allows the
  • the invention consists, apart from the arrangements set out above, of a certain number of other arrangements which will be more explicitly discussed below in connection with an exemplary embodiment described with reference to the attached drawing, but which is by no means limiting.
  • Figure 1 of this drawing is an axial vertical section of a latch at rest according to an embodiment of the invention.
  • Figure 2 shows, similarly to Figure 1, the lock while a conforming key has been introduced and the threshing machine has moved in translation.
  • Figure 3 is a section along line III-III, Figure 1.
  • Figure 4 is a partial top view of openings of the rotor intended to be crossed by a selection member.
  • a latch 1 comprising a stator 2 in which is rotatably mounted, for an angular range of extent A ( Figure 3), a rotor 3 linked in rotation to a threshing machine 4 , suitable for controlling a lock mechanism.
  • the rotor 3 and the thresher 4 form a single piece and it will be considered, subsequently, that the rotor and the thresher are combined.
  • the two parts could however be produced separately, means of link at least in rotation being provided between the two parts.
  • Selection members 5, constituted by flakes 6 are mounted to move radially in chambers 7 of the stator.
  • the flakes 6 have their mean plane orthogonal to the axis of the stator and are parallel, being arranged one behind the other.
  • Each straw is biased radially inward by a spring 8 compressed between the outer end of the straw and an outer cylindrical wall secured to the stator 2.
  • Each straw 6 has two enlarged ends 6 a , 6 b and a narrower intermediate part 6 c .
  • the edge of the inner end 6b , projecting into the housing 9, has a convex shape as visible in FIG. 3.
  • the rotor 3, the far side of the cam 4, comprises a cylindrical sleeve 3 is slidably and rotatably in an annular chamber 10 provided in the stator 2.
  • the chamber 10 is closed by a transverse wall 11 of the inlet side of the key, while this chamber 10 opens, on the opposite side, into a bore 12 which opens to the outside.
  • the portion 3b of the rotor housed in this bore has a greater radial thickness than the sleeve 3 has its inner cylindrical surface and defines a bore 3 c in the extension of the housing 9.
  • Springs 13 are provided between the inner end of the sleeve 3 a and the wall 11, to work in compression and to push the rotor 3 so as to have a tendency to move it away from the wall 11.
  • Each wafer 6 passes through a corresponding opening 14 provided in the sleeve 3 has the rotor.
  • the dimension, or axial thickness, of an opening 14 in a direction parallel to the common axis of the rotor and the stator, is greater than twice the thickness of a straw 6.
  • the opening 14 comprises a part 14 a ( see Figure 4), closer to the thresher, of reduced angular extent substantially corresponding to that of the enlarged end 6a of the associated tumbler.
  • the part 14 a communicates with a part 14 b (FIG. 4) of greater angular extent, equal to A (FIG. 3), located towards the wall 11.
  • the communication between the two parts 14 a , 14 b is ensured by a passage 14 c whose width is just sufficient to allow the passage of the narrow part 6 c of the glitter.
  • the axial dimension of the part 14b is sufficient for the thickness of the straw to be engaged in this part.
  • Connection means L are provided to establish a rotational connection between the rotor 3 and a conforming key 15 inserted into the housing 9 of the stator, when all the flakes 6 have been correctly erased.
  • These connecting means L, retractable include, on the side of the rotor 3, a radially movable pin 16 comprising a head 16 has stronger diameter protruding outwardly, in a recess 17 of the stator 18 having a clean ramp push the pin 16 radially inward when the rotor 3 slides.
  • This pin 16 comprises a rod 16 b of smaller diameter, integral with the head 16 a , suitable for passing through the bottom of a blind bore, provided in the part 3 b of the rotor, to project into the bore 3 c extending the housing 9.
  • a helical spring 19, arranged around the rod 16 b , between the bottom of the housing and the head 16 a is capable of pushing the pin 16 outwards to keep it in abutment against the ramp 18.
  • the recess 17 is aligned with the recesses of the stator 2 in which the springs 8 of the flakes are housed, these recesses opening onto the outside of the surface of the stator. These recesses are closed by an attached part 20 fixed on the stator, part on which the ramp 18 is provided.
  • the key 15, as visible in FIG. 2, comprises a rod of revolution comprising parts of different diameters (connected by frustoconical transition surfaces) arranged so that, when the key 15 has been inserted in the housing 9 of the stator , the flakes 6 are correctly erased, that is to say that all the intermediate parts 6 c are aligned to the right of the thickness of the sleeve 3 a , which allows the rotor 3 and the threshing machine 4 to move, under the action of spring 13, to the left of the drawing according to the representation.
  • the key 15 comprises, at the end, a recess 21 in which is suitable for engaging the end of the rod 16 b .
  • the angular extent of this recess 21 is substantially equal to that of the rod 16b so that the connection in rotation between the key 15 and the rotor 3 is ensured substantially without angular play.
  • a torsion spring 22 is provided around the end of the stator 2 adjacent to the thresher to exert a return torque of the thresher 4 relative to the stator 2 and to return the thresher to the zero position.
  • the parts In the zero position, or rest position, the parts are in the positions shown in FIG. 1 and the flakes 6 block the rotor 3 in translation and in rotation with respect to the stator 2 because the enlarged heads 6 have flakes are engaged, at least partially, in part 14 a , of reduced angular extent, of the corresponding opening 14.
  • the sliding movement of the rotor 3 causes the head 16 a of the pin 16 to cooperate with the ramp 18.
  • the pin 16 is therefore pushed radially inwards and its rod enters the recess 21 establishing the rotational connection between the key 15 and the assembly of the rotor 3 and of the thresher 4.
  • the recess 21 is not located in line with the rod 16 b , because the key is introduced in any relative angular position. It follows that the alignment of the parts 6 c is ensured but that the pin 16 cannot descend radially inwards because the rod of this pin comes into abutment against the cylindrical end of the key 15 in an area where the obviously 21 is not present. It suffices for the user to turn the key, in the lock, a little less than one turn, in any direction, so that the recess 21 passes in front of the rod 16b . At this moment, under the thrust of the springs 13 and the action of the ramp 18, the rod 16b can enter the recess 21 and the rotor, with the thresher 4, move in translation.
  • the user By rotating the key 15, the user drives the rotor 3 and the threshing machine 4, within the angular range A and controls the lock.
  • the withdrawal of the key 15 causes the rotor 3 and the thresher 4 to retreat by cooperation of the rod 16b and the end of the recess 17 furthest from the key entry.
  • the locking in translation of the rotor 3, relative to the stator 2, in the retracted position, is ensured by the displacement of the flakes 6 which are no longer correctly erased.
  • the non-conforming key will rotate freely inside the stator 2 and the rotor 3, without controlling the thresher 4.
