Definitions
- the invention relates to a blocking device, in particular an anti-theft device, for a lock actuator or electric lock, in particular for a door lock of a motor vehicle, a device of the type of those which include, on the one hand , a lock intended to block an actuator control rod, this lock, when actuated, opposing manual action on a frieze zipper, or equivalent, linked to the control rod, said lock being able to be moved transversely relative to the direction of movement of the control rod, and to cooperate with abutment surfaces provided on this rod and, on the other hand, means for driving the lock.
- a device of this kind is, for example, described in patent document DE-A 3 247 018.
- the frieze zipper allows manual unlocking of the lock on the side opposite the entry of the key.
- the frieze zipper allows, from the inside, to control the lock and, for example, unlock it if the door has been closed from the outside. If the door glass is broken, access to the frieze pull is permitted and the door can be opened after unlocking the lock.
- the blocking devices proposed to date require improvement both from the point of view of their simplicity of construction, and from the point of view of the safety of their operation.
- the object of the invention is, above all, to provide a locking device for an actuator, of the type defined above, which better meets the various requirements of practice than hitherto and which, in particular, is of simple construction and economical and has high operating reliability. It is further desired that this blocking device can be controlled without problem by an electric motor or equivalent.
- a blocking device in particular an anti-theft device, for a lock actuator or electric lock, in particular for the door lock of a motor vehicle, of the kind defined above, is characterized in that the above means for driving the lock comprise elastic means arranged between the lock and a thrust member, so that the force intended to move the lock in the direction corresponding to the blocking of the control rod, is transmitted by the above means elastic, sufficient space being provided between the thrust member and the latch, in the direction of movement of the latch, to allow the elastic means to absorb the displacement of the thrust member if the latch encounters an obstacle and is arrested in his displacement.
- the drive means can come directly into contact with the lock or a part secured to the lock to control the movement of this lock in the direction which causes unlocking.
- the drive means may comprise a rotary cam capable of acting on the thrust member and on the latch or an integral part of this latch, depending on the direction of rotation of the cam.
- This rotary cam is advantageously constituted by an eccentric disc.
- a rectangular light can be passed through the lock, two sides of which are parallel to the direction of movement of the lock, the said rotary cam being disposed inside this light so as to cooperate with the rear part of the light remote from the area of the lock intended to cooperate with the abutment surfaces of the said control rod, the aforesaid thrust member also being placed in this light on the side of the cam opposite to the rear part of the light, the said elastic means being placed between the thrust member and a front transverse edge of said lumen.
- a blind hole can be provided in the thrust member and in the aforesaid transverse front edge to serve as housing for part of the elastic means.
- These elastic means are preferably constituted by a helical compression spring.
- the pushing member can be formed by a piece with a U-shaped cross section, the aforesaid cam being housed in the concavity of the U, while the branches of this U are in sliding contact with the faces of the light of the lock which are parallel to the direction of movement of this lock.
- the control rod may include a rack, the teeth of which constitute the abutment surfaces; the lock is then constituted by a comb, or the like, and comprises complementary teeth capable of engaging between those of the rack.
- the drive means advantageously include an electric motor capable of driving the above-mentioned rotary cam in rotation in order to control the locking or unlocking.
- the invention also relates to a lock equipped with a blocking device as defined above.
- a locking device D for an actuator 1, more particularly a door lock actuator of a motor vehicle comprises, on the one hand, a lock 2 intended to block a control rod 3 of the actuator and, on the other hand, drive means 4 for the lock 2.
- this rod 3 acts, in a conventional manner, on a mechanism not shown, making it possible to move a lever; an example of a mechanism associated with the control rod is described in patent FR No. 82-17072 filed on October 12, 1982 in the name of the plaintiff and published under the number 2,534,303. It is sufficient to refer to this document for more in detail on a mechanism capable of being associated with control rod 3.
- the latch 2 when actuated and occupies the locking position shown in Figures 1 and 2, is adapted to oppose a manual action on a frieze zipper (not shown), or equivalent, linked to the rod control 3, for example by means of an ear 5 provided with a hole 6, provided at the end of the rod 3.
- the lock 2 is suitable for being moved transversely, and, generally, orthogonally to the direction A of the movement of the rod 3.
- the rod 3 can be moved in translation, in this direction A, by any appropriate means, in particular due to the cooperation of a screw 7, driven in rotation but immobilized in direction A, with a nut immobilized in rotation, but which can move in translation in direction A, this nut being linked to the rod 3.
- Control of the rotation of the screw 7 perhaps provided by an electric motor not shown in Figure 1.
- the axial end 8 of the screw 7 is arranged in the form of a pin mounted in a plain bearing.
- the drive means 4 of the lock 2 (see FIGS. 1 and 2) comprise elastic means 9 arranged between the lock 2 and a pushing member 10, so that the force intended to move the lock 2 in the corresponding direction when the rod 3 is blocked is transmitted by the above elastic means 9.
- Sufficient space is provided between the thrust member 10 and the latch 2 to allow the elastic means 9 to absorb the displacement of the thrust member 10 , if the latch 2 encounters an obstacle and is stopped in its movement as shown in FIGS. 3 and 4.
- the drive means 4 come directly into contact with the lock 2 (see Figures 5 and 6) or a part integral with this lock, to control the movement of said lock in the direction which causes unlocking.
- the drive means 4 comprise a rotary cam 11 advantageously constituted by an eccentric disc 12. This disc 12 is locked in rotation on a shaft 13 whose geometric axis is offset relative to the center of the disc 12.
- the shaft 13 is advantageously constituted by the output shaft of an electric motor 14 housed inside of the housing 15 of the actuator.
- the shaft 13 is parallel to the direction A.
- the lock 2 is constituted by a sort of plate with a rectangular outline, the mean plane of this plate being orthogonal to direction A.
- the plate constituting the lock 2 is mounted in a housing 16 (FIG. 1) of the housing 15, the mean plane is orthogonal to tree 13; this housing 16 has two parallel faces 17 serving to guide the movements of the plate constituting the lock 2.
- This lock 2 is crossed by a light 18 of rectangular shape, opening onto the two large flat faces of the lock 2.
- Two sides 19, 20 of the light 18 are parallel to the direction of movement of the lock and are intended to serve as a guide for the thrust member 10.
- the rotary cam 11 is disposed inside the light 18 so as to be able to cooperate with the rear part 21 of the light, this part 21 being distant from the front zone 22 of the latch 2 intended to cooperate with the abutment surfaces B of the said control rod 3.
- the pushing member 10 is also placed in the slot 18; this member 10 is located on the side of the cam 11 opposite the rear part 21 of the slot 18.
- the elastic means 9 are placed between the thrust member 10 and the front transverse edge 23 of the slot 18.
- the elastic means 9 advantageously consist of a helical compression spring 24, the ends of which are engaged in blind holes 25, 26 provided respectively in the thrust member 10 and in the transverse edge 23.
- the pushing member 10 as visible in FIG. 2, is advantageously formed by a part with a U-shaped cross section turning its concavity towards the rear part 21 of the slot 18.
- the cam 11 is housed in the concavity of the U and the branches of this U are in sliding contact, through their outer surfaces, with the faces 19, 20 of the slot 18 of the lock.
- the control rod 3 comprises, on its longitudinal edge turned towards the latch 2, a rack 27 whose teeth 28 constitute, by their lateral surfaces substantially orthogonal to the longitudinal axis of the rod 3, the abutment surfaces B.
- the rod 3 may include a central longitudinal opening 29 between two branches of this rod 3. This opening 29 is suitable for receiving the screw 7.
- the ex hoppers of the branches of the rod 3 projecting from the housing 15 are joined by a transverse plate 30 secured to the ear 5.
- the latch 2 comprises, on its face turned towards the rod 3, complementary teeth 31, two in number according to the embodiment of Figure 1, suitable for engaging between those 28 of the rack.
- the power to the electric motor 14 is controlled so that this motor rotates in a direction which causes moving the lock 2 in the direction of the rod 3, in order to engage the teeth 31 of the lock 2 between those 28 of the rack.
- the direction of rotation of the eccentric 12 and therefore of the shaft 13 of the motor which allows such movement of the lock 2 to ensure the locking corresponds to the direction of rotation of the hands of a watch.
- the locking position is ensured maintained because the spring 24 keeps the thrust member 10 in contact with the cam 11 and the latch 2 in contact with the rod 3, which prevents any untimely movement of the device, due to vibrations for example.
- the unlocking of the rod 3 is obtained by controlling the rotation of the shaft 13 and of the motor 14 in the opposite direction to that which caused the locking. According to the representation of Figure 5, this movement corresponds to a rotation of the cam 11 in the counterclockwise direction.
- the unlocking position is ensured maintained because the spring 24 keeps the thrust member 10 in contact with the cam 11, and the latch 2 in contact with the housing 15, which prevents any untimely movement of the device due to vibrations for example.
- the locking device is of a simple embodiment, while being of a particularly safe operation.
