Definitions
- Anti-theft fastening device for fastening a wheel to the hub of a motor vehicle.
- the present invention relates to an antitheft fastening device for securing a wheel on the hub of a motor vehicle, comprising a threaded distal portion, a holding portion intended to be applied against the rim of the wheel to be fixed, and a proximal driving portion, intended to be buried in a well of said rim, and which allows the transmission to said threaded portion of a tightening or loosening torque through a key or the like, the coupling of the key or the like with said driving part being made through concordant impressions which comprise on the one hand said drive part and on the other hand said key or the like, the shape, dimensions and positioning characteristics of said fingerprints constituting a code.
- each of the wheels that at least one of the fastening screws has a head which requires a special key to be able to be maneuvered.
- Numerous screw devices or the like are thus known, provided with coding means, for example those described in documents GB 2.006.371, FR 2.359.730 and FR 2.567.215 and WO 03/081057.
- These devices comprise on the one hand a screw whose head has either peripheral and / or facial notches arranged angularly irregularly, and on the other hand a socket-type key provided with pins or fingers arranged according to the same arrangement and intended to to cooperate with said notches in order to achieve the coupling capable of allowing the transfer of torque.
- the inviolability of these devices is increased when the rim of the wheel is provided with narrow and deep wells for burying the screw heads, preventing their grip by a lateral approach by means of a clamping tool.
- the fraudulent attempts against these devices are practiced in force, either by an axial attack and slightly biased with a burin, or by using a key presenting another code, or a part of the code, and by stamping it axially against the coded head.
- the object of the present invention is to propose an antitheft fastening device for fastening a wheel to the hub of a motor vehicle, making it possible to overcome this disadvantage.
- the antitheft fastening device for fastening a wheel to the hub of a motor vehicle comprises a threaded distal portion, a holding part intended to be applied against the rim of the wheel to be fixed, and a part proximal drive, intended to be buried in a well of said rim, and which allows the transmission to said threaded portion of a tightening torque or loosening through a key or the like, the coupling of the key or analogous with said driving portion being achieved through concordant impressions that comprise on the one hand said drive portion and on the other hand said key or the like, the shape, dimension and positioning characteristics of said fingerprints constituting a code, and it is characterized in that:
- said proximal drive portion is chosen to have a diameter close to that inside said well
- said indentations that comprise said proximal drive portion are formed on the periphery thereof opposite the inner wall of said well when said fixing device is in position to maintain said wheel, and they are shallow, - said proximal drive portion is surmounted by an element which covers and which is able to pivot freely and axially.
- the indentations that comprise said proximal drive portion are in the form of an alternation, peripherally, of recessed areas and in relief, and forming slots distributed around the periphery of the proximal training part.
- the raised areas form a partial frustoconical segment, that is to say that the outer wall of each of them is tapered, inclined towards the proximal end.
- each zone in relief has at least one lateral edge, that on which the loosening torque must be exerted, which is beveled, that is to say inclined relative to the adjacent hollow area.
- the proximal portion comprises a cylindrical axial extension, on which is threaded the element able to pivot freely and axially, which comprises for this purpose an axial channel whose extreme orifice has a chamfer, while the end portion of said extension comprises an axial blind hole which, after placement of said element, is flared through a crimping operation, so that the end portion extends into the chamfer.
- FIG. 1 shows a schematic perspective view of an antitheft device according to the invention.
- FIG. 2 shows a schematic perspective view of the same antitheft device in use situation.
- FIG. 3a, 3b and 3c show sectional views along a median axial plane of the same antitheft device, and corresponding to different steps of manufacturing said device.
- FIG. 4 shows a perspective view of a tool for maneuvering in tightening or loosening the antitheft device according to the invention.
- an antitheft device 1 according to the invention can be seen.
- This antitheft device 1 comprises a distal threaded portion 2 intended to pass through the rim of the wheel to be fixed to a hub, and to be screwed into this hub; an intermediate portion 3, which is in the form of a disc and intended to be applied against the rim, and in this case associated with a washer 30; and a proximal drive portion 4, which allows the transmission to said threaded distal portion 2 of a tightening or loosening torque through a tool 5 such as that shown in FIG. 4.
- the proximal drive portion 4 consists of an extension of the disk consisting of the intermediate holding portion 3, in the peripheral face 40 of which are made notches 41, which form a recess matching the profile of the tool 5, way to allow the transmission of a couple.
- the peripheral face 40 consists of a frustoconical profile wall whose diameter narrows more closely to the proximal portion 4.
- notches 41 are made by cold forging, which avoids resorting to complex machining operations.
- the notches 41 create an alternation of recessed areas and raised areas 42, to form slots.
- the number and non-regular distribution of the notches 41 create code.
- a rim 6 to be fixed through anti-theft devices 1 according to the invention and more precisely a portion of the rim 6, which has a hole 60 for the passage of the threaded distal portion 2, this hole 60 being formed in the bottom of a well 61 adapted to allow the burial of the intermediate holding portion 3 and the proximal portion 4.
- transverse dimensions of the proximal portion 4, and more exactly at the peripheral face 40, are very close to those internal to the well 61.
- the notches 41 are shallow in the radial direction, so that the space which extends between the bottom 43 of a notch 41 and the inner wall 62 of the well 61, is narrow, so as to make it impossible introducing into the well 61 a clamping tool.
- each raised area 41 has two beveled side edges 44, that is, they do not extend in radial planes, but are inclined relative to the bottoms 43 of the adjacent slots 41.
- the proximal portion 4 is surmounted by an element 7 in this case in the form of a ring, able to pivot axially freely.
- the proximal portion 4 has a cylindrical axial extension 45 on which the element 7 is threaded via an axial channel 70 whose end orifice has a 71.
- the end portion 46 of the extension 45 comprises an axial blind hole 47 which, after placement of the element 7 (FIG. 3b), is flared (FIG. 3c) through a crimping operation, so that the end part 46 extends in the chamfer 71, so as to carry out the holding, with the possibility of axial pivoting, of the element 7.
- This key 5 is in the form of a tip having an end 50 is shaped to allow its adaptation to a tool, in this case this end is, not limited to, hexagonal shape, and the other end consists of a cylindrical sleeve 51, the end edge is cut to form an alternation of crenellations 52 and teeth 53, so complementary to the slots formed by the hollow zones 41 and the relief zones 42.
- the number, the distribution and the shape of the recessed areas 41 constitute a code that is difficult to circumvent, especially since the proximal portion 4 is buried at the bottom of the well 61, and that makes it difficult to read this code. .
- the shape of the raised areas 42 essentially the inclinations of the face 40 and the edges 44, prevents the transmission of a torque by means of a universal key, manufactured for the occasion and having only one tooth 53, which could only escape during a training attempt.
