Definitions
- the invention relates to the opening locks of a motor vehicle.
- an edge of the track for example the upper edge, ensures the positioning of the half-flakes on the left in the rotor while the other edge, for example the lower edge. , ensures the positioning of half glitters located on the right. It usually follows a complicated track shape so that the key is difficult and expensive to manufacture.
- An object of the invention is to provide a lock with a large number of possible combinations but whose key is easier to manufacture.
- a lock device for opening a vehicle which comprises:
- a latch comprising half-flakes forming two subassemblies extending facing one another;
- a key having, on distinct faces, tracks having non-rectilinear edges capable of cooperating with the half-glitters to unlock the latch, each track having a dimension, measured from one to the other of the edges in a direction perpendicular to a longitudinal direction of the key, constant when traversing the longitudinal direction.
- each track on the key can be made for example by means of a single passage of a cutter.
- the simplification of manufacturing does not lead to compromise on safety. Indeed, the presence of half-glitter provides a number of possible combinations that remains very high.
- the tracks are identical in axial symmetry between them.
- This embodiment makes it possible to house the key indifferently in one or the other of two symmetrical positions with respect to a longitudinal axis of the key. We are therefore in the presence of a reversible key.
- This embodiment can be achieved by placing flakes so that their coding protuberances are identical in axial symmetry on both sides of the housing of the lock for receiving the key.
- the number of combinations that can be envisaged if sixteen half-straws are provided is about 8000, which provides a high degree of security.
- This type of lock remains difficult to force since its opening requires the positioning of all half-glitters which are movable independently of each other.
- the tracks have different shapes from each other.
- the key is irreversible so that it must be introduced into the lock by respecting one of the two aforementioned positions.
- each side of the key is then associated with an independent code on the other side.
- 8000 codes are obtained on one side and 8000 codes on the other, which makes a total of sixty-four combinations. million which can all be used without additional prohibition insofar as both sides are independent.
- This embodiment requires a particular positioning of the key but offers a much greater number of combinations and a level of security to match.
- the forcing is very difficult since it requires the independent positioning of each half-glitter.
- each half-straw of a subset extends opposite a half-straw of the other subset.
- the key and the lock can be given a reduced length.
- each subassembly comprises half-flakes capable of protruding from different respective faces of a frame of a rotor of the latch.
- the device comprises for each half-straw a return member in position, specific to the half-straw.
- the key has rectilinear upper and lower edges.
- the faces of the key are flat.
- a bolt for a vehicle opening which comprises half-flakes forming two subassemblies extending facing one another, the half-flakes being able to cooperate, to unlock the vehicle. latch, with a key having on tracks distinct tracks having non-rectilinear edges, each track having a dimension, measured from one to the other of the edges in a direction perpendicular to a longitudinal direction of the key, constant when we go through the longitudinal direction.
- This lock is recognizable by the fact that it can be unlocked by means of a key of the aforementioned type.
- a key for a vehicle door latch which has tracks on opposite faces having non-rectilinear edges, each track having a dimension, measured from one to the other of the following edges. a direction perpendicular to a longitudinal direction of the key, constant when traveling in the longitudinal direction.
- FIG. 1 is an exploded perspective view of some parts of a lock according to the invention with its key;
- FIG. 1 is a perspective view of the same parts in the assembled state
- FIG. 3 is a partial sectional view of the lock of FIG. plane perpendicular to its longitudinal axis;
- FIG. 4 shows two elevational views of two sides of the lock key of Figure 1 in a first embodiment
- Figure 5 is a figure similar to Figure 4 showing the key in a second embodiment.
- FIGS. 1 to 3 illustrate a rotating barrel lock 2 which is intended to equip a device for locking and unlocking an opening leaf of a motor vehicle.
- This lock is part of a device 4 which also comprises a key 6 for actuating the lock for unlocking.
- the key comprises an insert 8 having a general rectangular parallelepiped shape.
- the directions Y and Z are perpendicular to the direction X.
- the direction Y extends according to the thickness of the key while the direction Z extends along its width or its height.
- the insert 8 has a length in the X direction very large compared to its width in the Z direction, itself large in front of its thickness in the Y direction.
- the insert 8 has two planar main faces 10 oriented in opposite directions. and each perpendicular to the Y direction.
- Each of the faces 10 has a track 12 carved in this face from a front end 13 of the insert and extending in the longitudinal direction X towards the other end.
- Each track 12 starts the corresponding face on a constant thickness in the direction Y. It is delimited in the direction Z by two opposite edges 14 and 16 facing each other and extending opposite one another. These edges have non-rectilinear shapes.
- Figure 1 shows the rotor 20 of the lock.
- the lock further comprises a stator which is of a conventional type and has not been illustrated. Reference is made to this subject for other conventional aspects of the on-demand lock FR-2 882 081 in the name of the applicant, for example.
- the latch comprises movable half-flakes 22 received in respective locations 24 of the rotor provided for this purpose.
- Each of the half-flakes 22 has a generally flat shape delimited by a circumferential edge having a suitable shape.
- the half-flakes 22 and the locations 24 are divided into two subsets 26 and 28 extending on either side of a median longitudinal plane of the lock and therefore in particular on both sides of the axis.
- the half-flakes 22 extend from and other of the housing 34. All the half-glitters are parallel to each other.
- the two subassemblies have the same number of half-flakes 22, in this case equal to eight for a total of sixteen half-flakes in the latch.
- the half-flakes are placed in correspondence and coincidence from one subset to another.
- Each half-straw of one of the subassemblies thus extends in coincidence with a half-straw of the other subassembly, the two half-straws being coplanar and facing one another.
- the rotor 20 comprises, for each half-flap, return means 38 formed here by a spring bearing on the one hand against a frame of the rotor 20 and on the other hand against a protuberance of the half-flake.
- Each half-straw is mounted movable in the direction Z relative to the frame so as to extend projecting from the frame, out of the latter, in the upper part of the rotor for some of the half-flakes and in the lower part of the rotor for other half-glitter.
- some, here four in number, half glitters of the left subassembly are biased upwards by their return member so that they extend in the absence of the key protruding from an upper face of the rotor. It is the same for some, here four in number, half glitters of the right subset. All these half-glitters are illustrated above the frame in Figure 1.
- Each half-flake comprises an internal protuberance or relief 40 extending into the housing 34 and towards the semi-flake lying opposite.
- the protrusion is intended to cooperate with one of the tracks 12 of the key when it is inserted into the housing.
- the key and the tracks are arranged so that each track is associated with the respective one of the left and right subsets.
- one of the edges 14 or 16 cooperates with the protuberances 40 of the subassembly associated with the track in order to maneuver the half-glitters by a cam effect until they are placed in a position where they do not extend protruding from the faces of the rotor.
- the half-glitters are therefore in the erased position.
- each of the half-glitters is movable relative to the frame independently of all other half-glitters.
- the unlocking is obtained solely by cooperation of the tracks 12 with the half-glitter of the two subassemblies.
- each of the tracks 12 is provided so that the width f of the track is constant along the track when it travels along the direction X. This width is measured next Z direction. Under these conditions, the two edges 14 and 16, although they are not rectilinear, follow each other along the direction X.
- the key is reversible. It can therefore be introduced into the housing 34 in order to obtain the unlocking in any one of the two symmetrical positions of the other relative to the longitudinal axis of the key which corresponds to the axis 32 when this one is in the housing. The user does not have to worry about inserting the key in one of these positions.
- the two tracks 12 are identical to each other and occupy symmetrical positions with respect to the axis of symmetry of the insert e.
- the two sub-sets of flakes are configured so that, in the unlocked position, the protuberances 40 also occupy positions symmetrical to each other within each pair of half-flakes placed in correspondence. We can predict for example that it is the entire half-straw which is symmetrical to the other. Therefore, the position of the protuberances 40 on one of the subassemblies completely determines the position of the protuberances 40 of the other subassembly.
- the second embodiment has been illustrated in Figure 5. It differs from the previous only in that the key is not reversible. Under these conditions, the user must take care to introduce it into the housing 34 respecting a particular positioning, in other words it is the predetermined one of the two faces of the insert which must always come opposite one of the housing faces. In other words, from the position of the key in the housing which allows to obtain the unlocking, we can not obtain the unlocking by reintroducing the key after making it turn around its axis.
- the width f of each track is as previously constant when traversing the track along the direction X.
- the two tracks this time have different shapes from each other. It follows that the configuration of one of the sub-sets of flakes is in no way determined by the configuration of the other. For example, in the presence of sixteen half-glitter, we obtain sixty-four million possible combinations by providing that each half-straw can have four different positions in the direction Z.
- each mode only the combinations in which four of the half-flakes of the same subassembly extend above the axis and four others extend below the axis will be retained.
- the manufacture of the keys in these two embodiments is particularly simple. Indeed, given the constant width t, a single cutter passage makes it possible to make the track on the corresponding face of the key.
- the manufacturing costs are reduced and the lock is associated with a high level of security even if the number of possible combinations is greater in the second mode than in the first.
