- a motor vehicle steering lock comprising a housing in which a rotor is rotatably mounted between an angular rest position (also called a stop position) in which a suitable key can be inserted, front to back, or withdrawn axially from rear to front, and at least one angular position of use, in which the key can not be extracted from the rotor, the rotor having a rotary output member forming a cam which is capable of cooperating with a control finger carried by a slider to control the movements of the latter.
- the slider is slidably mounted in the housing in an axial direction, between a rear anti-theft position to which it is resiliently biased and in which it projects axially rearwardly through an opening of the housing for rotationally locking a housing member.
- a feeler located in the vicinity of the rotor inlet can be urged by the key when it is introduced into said rotor
- the invention has the following additional features taken in isolation or in combination:
- the blade may be articulated around a hinge integral with the body, this hinge having as axis of rotation an axis located on the body and perpendicular to the axis of rotation of the rotor, the elastic means tending to bring the front end closer together the blade radially towards the center of the rotor may be a compression spring placed between the body and the blade.
- the blade may be an elastic blade fixed in its rear part to the body; the elastic blade may have such a shape at rest that it has a natural tendency to move towards the inside of the rotor, so that when the rotor is in the stop position and the key is withdrawn, the slider is free to be pushed by the elastic means towards the rear of the lock to block the direction, and that when the key is inserted into the lock, the tilting probe being in position out, the slide being driven by the slope of the cam towards the front of the lock, the hook of the elastic blade of the slide comes around the tilting probe to come hook so that the slide and thus the bolt is maintained in position of security.
- the blade may comprise, at its rear part, a folding constituting an abutment for taking up force, this part passing through a first central orifice of the slider,
- the blade may comprise in its front part a folding constituting an arming stop limiting the radial displacement of the flexible blade,
- the blade may comprise in its front part a folding constituting a lateral guide member to the extent that this folding can slide laterally in a notch of the slider provided for this purpose, the probe can be articulated along an axis perpendicular to the axis of the rotor
- the control finger can be rotatably mounted about a radial axis to reduce friction between the control finger and the cam.
- the cam may be made of plastic materials possibly loaded with high-strength fibers, especially in the case where the control finger is rotatably mounted around a radial axis
- the cam may be made of zinc alloy and aluminum.
- the probe may be made of zinc alloy and aluminum or plastic materials.
- the elastic blade may be made of spring steel or beryllium copper heat treated - the elastic blade and the body of the slider can be made from the same piece by cutting and stamping.
- Figure 1 schematically shows a section of a lock according to the invention, the key being inserted into the rotor, the rotor being in the stop position, the slide being in the retracted position.
- Figure 2 shows schematically a section of a lock according to the invention, the key being removed from the rotor, the rotor being in the stop position, the slide being in the extended position.
- FIG. 3 schematically shows a section of a lock according to the invention, the key being inserted into the rotor, the rotor being driven by the key in rotation, and the slide being driven in axial translation towards the front of the lock, by through the slope of the cam acting on the control finger of the slider,
- FIG. 4A schematically shows the slide comprising an articulated blade, a compression spring tending to driving the slider back of the latch and a compression spring between the blade and the body tending to drive the front end of the blade radially inwardly of the rotor.
- Figure 4B shows schematically in exploded view the slide composed of a body and an elastic blade.
- Figure 5 shows schematically a perspective view of a cam.
- the device mainly comprises a housing 1, a rotor 2, a key 3, a tilting probe 4, a spring 1 10, a slide 100 equipped with a blade elastic 130, a control finger 140 and a cam 8 integral with the rotor 2.
- Figure 1 shows a section of the front part of the lock.
- the key 3 is inserted into the rotor 2.
- the cam 8 is secured at the end of the rotor.
- the tilting probe 4 can rotate about an axis 43 perpendicular to the axis of the rotor.
- the key pushes on the rocking finger 4 and hooks the flexible blade 130 which is secured longitudinally with the body 100 of the slide.
- FIG. 3 shows the lock while the key 3 has been inserted in the rotor 2.
- the finger 140 is forced to follow the ramp of the cam and forces the slide 100 to move according to the arrow V.
- the flexible blade 130 is pushed by the rocking finger 4 which slides on the gently sloping portion of the hook placed at the end of the flexible blade, to return to the end position in the fully retracted position of FIG.
- the housing 1 comprises a front 1 1 of introduction of the key, and a rear face 12.
- This housing comprises a substantially circular orifice for housing the rotor and the cam. It further comprises an axial housing forming a slide.
- the rotor 2 is rotatably mounted in the housing. It includes an opening on the side of the front of the housing for the introduction of the key.
- the key 3 can be introduced into the rotor by the front face of the housing.
- the tilting probe 4 comprises an upper portion 41 cooperating with the lower part of the key 3, a lower portion 42 in the form of a hook, and an axis of rotation 43 perpendicular to the axis of the rotor.
- the spring 1 10 works in compression. It rests at one of its ends on the bearing surface of the housing and on the other on a bearing surface of the slide.
- the slider 100 comprises at one end a portion 101 for mechanically connecting it to a locking bolt of the steering column of a vehicle. It also comprises on its lower part a bearing surface 120 allowing the support of the spring 1 10. This bearing surface is obtained by stamping the body of the slide.
- the slider slides in the axial housing of the housing provided for this purpose.
- the control finger 140 cooperates with the cam 8. Here this control finger is rotatably mounted on a stepped shaft traversed by a rivet for securing the assembly.
- a notch 102 guides the front end of the elastic blade laterally during its radial movement.
- the metal elastic blade 130 is here formed by stamping and then heat treated to optimize its mechanical characteristics. It can be made of spring steel or beryllium bronze for example.
- This elastic blade comprises six distinct zones Z1 to Z7 each providing a particular function.
- the rearmost zone Z1 comprises a 90 degree return entering a hole in the slider body provided for this purpose.
- the zone Z2 comprises a circular through orifice allowing the passage of a rivet allowing both the fixation of the flexible lamella on the body of the slider and the fixing of the control finger 140.
- the zone Z3 is a flexible flat surface.
- Zone Z4 is a surface substantially perpendicular to the body of the slider.
- Zone Z5 has a surface having a gentle slope so that when the slide passes from the extended position to the retracted position, the elastic blade is forced to approach the body of the slide to snap into the hook shape of the tilting probe. 4.
- Zone Z6 is substantially perpendicular to the body of the slider. The elastic blade in this zone Z6 is guided by the notch 102 of the body 100 of the slide.
- Z7 zone is a redan of the elastic blade which keeps the elastic blade in a rest position of the elastic blade and which corresponds to a position of the elastic blade farthest from the body of the slider.
- the cam 8 has a body 81 of generally cylindrical shape coaxial with the rotor, having a cavity opening at the cylindrical face through a successively defined orifice, from a first axial face F1 of the body, by an axial face F2, a radial face F3 extending at a short distance from the second radial face of the body, and a substantially helical curved face F4 which terminates at the first radial face of the body.
- the bottom of the cavity 120 has on the side of the first radial face of the body a cylindrical portion adjacent to the curved face followed by a concavity or clearance of substantially parallelepiped shape.
- It also has a cup shape C constituting a kind of ramp for guiding the tilting finger from the concavity to the cylindrical radial face along a path comprising a radial section bringing the finger against the curved face, then a curved section along from the curved face, to finally reach the cylindrical portion, before returning to the right of concavity the first radial face before returning to the concavity.
- control finger follows the cam (surface F4).
- the slide then moves towards the front of the rotor until the control finger arrives on the inner face of the cam (surface F1).
- the slide is then in the retracted position.
- the control finger follows the inner face (surface F1) of the cam which is a flat surface perpendicular to the axis XX '. During this movement the control finger and the slide do not move. The slider remains in the retracted position. Arriving near the stop position the control finger is no longer supported on the front face of the cam but in this case the slide is retained by the elastic blade whose surface Z4 is retained by the hook 42 of the tilting probe which prevents the control finger to enter the axial groove (C) of the cam.
- the spring 1 10 pushes the slide which tends to raise the hook of the tilting probe taking into account the respective slopes of the tilting probe hook and the zone Z4 of the elastic blade.
- the slide can then move backwards.
- the control finger freely enters the groove C of the cam.
- the slide is then in the extended position by driving the locking bolt of the vehicle direction.
- Figure 5 shows the relative positions of the control finger 140 relative to the cam. The finger passes successively from the position A to the position B then the positions C, D, then returns to position A after passing through the positions C and B.
