Definitions
- the present invention relates to a stator for glitter lock.
- a steering wheel lock of a motor vehicle 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rest position (also called a stop position) in which a suitable key can be introduced, forwards or backwards, or withdrawn axially from rear to front, and at least one angular position of use, in which the key can not be extracted from the rotor, the rotor comprising a rotary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.
- the steering column when the rotor is in the rest position, key extracted, and a retracted front position inside the housing.
- the invention more specifically relates to a motor vehicle lock, comprising a rotor mounted to rotate about its axis in a stator, in which flakes are slidably mounted in the rotor, in a transverse direction, between at least one projecting intermediate position. in which they immobilize in rotation the rotor with respect to the stator, and a retracted intermediate position in which they are received inside the rotor and towards which they are forced by the introduction into the rotor of a suitable key,
- the invention proposes a motor vehicle latch stator, this latch comprising a rotor rotatably mounted about an axis in the stator, rotor in which flakes of identical external shape are slidably mounted in the rotor, each straw comprising a guide portion having a guide width in translation and another locking part having a protruding width penetrating into the groove of the stator, in a transverse direction, between at least one projecting intermediate position in which they immobilize in rotation the rotor with respect to the stator while entering the groove of the stator provided for this purpose, and a retracted intermediate position in which they are received inside the rotor and towards which they are forced by the introduction into the rotor of a corresponding key, each straw consisting of a lamella of form substantially rectangular, the guide in slots of the rotor being carried by the guiding portion of the straw and the projecting portion being located along the length of the straw and at least at one end of the straw,
- this lock is characterized by the fact that the width of the groove of the stator receiving the flakes is very slightly greater than the projecting width of the flakes except at the right of at least one flake where locally the width of the groove of the stator receiving the flakes is clearly greater than the salient width of the flakes.
- the invention has the following additional features taken in isolation or in combination:
- the width of the groove of the stator receiving the flakes may be greater than the projecting width of the flakes by a few tenths of a millimeter and, in line with at least one flake, the width of the groove of the stator may be greater than the projecting width of the flakes at least about one millimeter.
- the width (L2) of the groove of the stator receiving the flakes may be less than the width (L3) of at least five tenths of a millimeter to ensure that at least one flake is not in contact with the stator when others are when the rotor is forced into rotation.
- the rotor may be in two parts, the central portion being made of plastic and the outer portion may constitute a metal sleeve to improve the wear properties and thus increase the life of the components of the lock.
- the metal sleeve may be zinc alloy and aluminum because this alloy is easily obtained by molding and offers acceptable mechanical characteristics.
- the stator may be obtained by pressure molding of plastics possibly loaded with high strength fibers to the extent that the mechanical properties of these materials are good and the cost of production in large series relatively low.
- Figure 1 shows a front view of a straw.
- Figure 2 shows a section of an assembly comprising a stator, a rotor, and a straw.
- Figure 3 shows a section of an assembly comprising a stator, a rotor, a flake and a key.
- Figure 4 shows an exploded perspective of a rotor, a key and flakes.
- Figure 5 shows a top view of a stator according to the invention.
- Figure 5bis shows an enlarged partial top view of a stator according to the invention or are shown the upper part of the flakes and their housing in the stator.
- FIG. 6 shows a section of the stator, rotor and flake assembly according to the AK plane according to the invention.
- Figure 7 shows a section of the stator assembly, rotor, flake according to the plane AD according to the invention.
- FIGS. 2, 3 and 4 show a rotor 10 comprising a series of housings 14 in which the flakes 12 can slide in a transverse direction perpendicular to the axis of the rotor 10.
- the flakes 12 are made substantially in the form of plates and they are slidably mounted between an intermediate projecting position which is shown in FIG. 2 and a retracted position shown in FIG. 3.
- the flakes 12 are guided in their housings 14 by two external lateral edges 34 of transverse orientation. These lateral edges constitute the useful surface guiding flakes.
- the flakes 12 When the flakes 12 are in the projecting position, that is to say when they are arranged partially outside the housings 14 of the rotor 10, the flakes 12 are intended to block any rotational movement of the rotor 10 with respect to a stator 15 (see Figure 2). On the contrary, when the flakes 12 are in the retracted position, the rotor 10 can rotate freely about its axis A1 in the stator 15.
- the flakes 12 are brought to their retracted position by means of a matching key 16 whose key shank 18 cooperates with the flakes 12 to cause them to slide inside the housings 14.
- the key rod 18 is intended to be introduced axially into a key passage which extends axially inside the rotor 10, the key rod 18 then being received inside a window 22 arranged in each of the Sequins 12.
- the key shank 18 is here of rectangular section, elongated in the sliding direction of the flakes.
- the key shaft 18 On each of its two opposite faces 24 which are parallel to the sliding direction of the flakes, the key shaft 18 comprises a cam path 26 which is recessed.
- Each flake 12 comprises a radial lug 28 which extends towards the inside of the window 22 from an edge 30 of the window 22 parallel to the transverse direction of sliding of the flake 12.
- This radial lug 28 is intended to be received in the cam path 26 of in order to exactly follow the profile so that an axial displacement of the key 16 causes a displacement of each of the flakes 12 according to their sliding direction.
- the cam path 26 is delimited by two parallel edges, but not rectilinear, which control the movements of the flakes 12 in both directions in the sliding direction.
- the position of the radial lug 28 on the edge 30 of the window 22 of each flake 12, and the profile of the cam path 26 of the key 16 are such that if the key is compliant, when the latter is axially engaged to bottom in the rotor 10, the flakes 12 are in the retracted position to release the latch lock.
- cam tracks 26 of each of the faces 24 open at the free front end of the key shank 18 where they disclose a flare intended to facilitate the entry of the lugs 28 in the cam path 26 when the introduction of the key 16 into the rotor 10.
- the present invention can be used with flakes comprising or not comprising a return spring. Here the chosen solution is without a spring.
- the cam path 26 in which the pins 28 are received causes a displacement of each straw 12 in its sliding direction so that when the key shaft 18 is completely removed, the flakes 12 are in their projecting position.
- each straw 12 comprises, on one of its lateral edges 34 parallel to the direction of sliding, a notch 36 within which the strip 32 of play catching is intended to be partially received.
- the strip 32 of clearance clearance which is fixed in the rotor 10, is capable of cooperating with transverse flanges 38 which delimit the notch 36 to limit the stroke of the flake 12, as is shown in the figures 2 and 3.
- the flakes 12 comprise, on the outer lateral edge 34 opposite to the one carrying the notch 36, an indexing nose 37 which extends transversely towards the outside. So that this indexing nose 37 does not hinder the sliding movement of the flake 12, the housings 14 of the rotor 10 are provided with a clearance 39 corresponding to the spout 37.
- the flakes may be blocked for example by deformation of the material of the rotor.
- a spring 19 working in compression can be placed between the rotor and each straw to maintain the flakes in the extended position when the key is removed.
- the useful translational guide width of the flakes LO is the same for all flakes.
- This width LO is very slightly less than the width of all the slots of the rotor to ensure minimal clearance gliding flakes in the slots of the rotor.
- the width L2 of the housing provided in the stator at the slots (F2, F4, F5, F6) is slightly greater than the width L1 of the flakes in order to ensure the easy entry and exit of the flakes in the stator housing but without excessive play.
- a slot L 3 is provided, L 3 being substantially greater than L 1 and L 2 so that the field of the flakes can never be in contact with the stator.
- the flakes corresponding to the slots Fl and F3 can not be hooked because they can not be wedged and pre-engaged with a hook in the stator by forced rotation of the rotor.
- the invention applies to many forms of keys having a section in the form of I (called “snake”), in the shape of + (called “wave”) or in the form of "MNPRS"
