Abstract

The anti-theft shield is used on a vehicle wheel nuts, comprising an adaptor (1) which is fixed onto the nut. The bottom (1b) of the adaptor incorporates blind holes (1e) engageable by pins (6) projecting from a special drive spanner (2), the number of holes equalling the number of pins. The geometrical layout of the holes matches that of the pins and can have equal or unequal hole spacings, together with angular or radial offsetting. The holes are set inside a collar (1g) to deny thieves access to the holes. The central area (1h) of the bottom surface may be raised by a nominal bevel, the tool head being locally recessed (2d) to accommodate the raised area with clearance.

Suivant l'Addition, on a voulu améliorer, d'une maniere ap prdciable, les moyens de l'invention et les résultats avantageux attendus. Following the addition, we wanted to improve, in a appreciable manner, the means of the invention and the expected advantageous results.

On rappelle, selon les caractéristiques du Brevet, que le dispositif comprend essentiellement un organe adaptateur ouvert au moins une extrémité en étant agencé intérieurement pour coiffer l'écrou ou autres organes à pans à protéger et pour être centré et positionné angulairement sur ledit écrou ; un ou des moyens coopérant avec ledit organe adaptateur et ltécrou ou autres, pour les rendre solidaires d'une manière indémontable ; 1 extrémité de l'organe adaptateur, opposée à l'extrémité d'engagement sur l'écrou ou autre, présentant un agencement ou conformation avec des creux et/ou des saillies destinés d coopérer avec des saillies et/ou des creux que présente, d'une manière complémentai re, l'extrémité (2a) d'un organe dentraSnement qui peut être par ailleurs conformé à l'autre extrémité avec des pans ou méplats ou autres moyens de coopération avec une clé classique de démontage. It will be recalled, according to the characteristics of the Patent, that the device essentially comprises an adapter member open at least one end while being arranged internally to cover the nut or other flange members to be protected and to be centered and angularly positioned on said nut; one or more means cooperating with said adapter member and the nut or the like, to make them integral in a non-removable manner; 1 end of the adapter member, opposite the engagement end on the nut or the like, having an arrangement or conformation with depressions and / or protrusions intended to cooperate with protrusions and / or depressions that this presents, in a complementary way, the end (2a) of a toothed member which can also be shaped at the other end with flats or flats or other means of cooperation with a conventional disassembly key.

Selon l'Addition, à partir de cette conception et des caractéristiques du Brevet, il a été conçu et mis au point une réalisation suivant laquelle, la face de l'organe adaptateur où débouchent les ouvertures, présente une collerette circulaire de faible épaisseur destinée à rendre difficile l'accès aux dites ouvertures en prévenance des actions malveillantes. According to the Addition, on the basis of this design and of the characteristics of the Patent, it has been designed and developed an embodiment according to which, the face of the adapter member where the openings open, has a thin circular collar intended to make it difficult to access said openings in order to prevent malicious actions.

Selon une autre caractéristique, une portée centraleest formée en débordement de la face de l'organe adaptateur où débouchent les ouvertures, pour rendre difficile l'accès aux dites ouvertures en combinaison avec la collerette notamment. According to another characteristic, a central bearing is formed in overflow from the face of the adapter member where the openings open, to make access to said openings difficult in particular with the flange.

Ces caractéristiques et d'autres encore ressortiront de la suite de la description. These characteristics and others will emerge from the following description.

Pour fixer ltobjet de l'Addition, sans toutefois le limiter, dans le dessin annexé
La figure 1 est une vue en perspective de l'organe adaptateur selon l'Addition.
To fix the object of the Addition, without however limiting it, in the attached drawing
Figure 1 is a perspective view of the adapter member according to the Addition.

La figure 2 est une vue en coupe longitudinale de l'organe adaptateur avec en regard et en alignement, organe d'entraîne- ment. FIG. 2 is a view in longitudinal section of the adapter member with, facing and in alignment, the drive member.

La figure 3 est une vue en coupe transversale cansidérée selon la ligne 3-3 de la figure 2. FIG. 3 is a cross-sectional view taken along line 3-3 of FIG. 2.

La figure 4 est une vue en coupe longitudinale du dispositif selon l'Addition positionné sur un écrou en vue de son serrage ou desserrage. Figure 4 is a longitudinal sectional view of the device according to the addition positioned on a nut for tightening or loosening.

Afin de rendre plus concret l'objet de l'Addition on le décrit maintenant d'une maniere non limitative en se référant à l' exemple des figures du dessin. In order to make the object of the Addition more concrete, it is now described in a nonlimiting manner with reference to the example of the figures in the drawing.

On rappelle pour une meilleure compréhension de la suite de la description, que le dispositif selon l'invention comprend un organe adaptateur (1) conformé pour coiffer et entre solidaire de l'écrou(E) relatif à l'assemblage à réaliser des deux-pièces (P et P1) (notamment et respectivement le moyeu et la jante). Un organe d'entraSnement (2) coopère avec l'organe adaptateur (1) et est actionné par une clé classique de manoeuvre (3) (figure 4). It will be recalled for a better understanding of the following description, that the device according to the invention comprises an adapter member (1) shaped to cover and between integral with the nut (E) relating to the assembly to be produced of the two- parts (P and P1) (in particular and respectively the hub and the rim). A drive member (2) cooperates with the adapter member (1) and is actuated by a conventional operating key (3) (Figure 4).

De mime, le fond tlb) de l'organe adaptateur (1) présente des trous borgnes (le) en nombre variable, disposés circulairement à intervalles réguliers ou non en étant décalés radialement ou non. Similarly, the bottom tlb) of the adapter member (1) has blind holes (le) in variable number, arranged circularly at regular intervals or not, being offset radially or not.

Dans ces trous (le) sont engagés et centrés les doigts (6) que présente en débordement, d'une manière correspondante, l'organe d' entraSnement (2).In these holes (the) are engaged and centered the fingers (6) that presents in overflow, in a corresponding manner, the drive member (2).

Suivant addition, la face (ldEde organe adaptateur où débouchent les trous (le), présente une collerette circulaire (1g) convenablement positionnée par rapport à la disposition de l'ensem- ble des trous (le) de sorte que lesdits trous sont situés à l'intérieur de la collerette qui rend ainSi difficile l'accès aux trous (le) en prévenance d'actions malveillantes. Cette collerette extérieure (zig) est relativement peu épaisse. According to addition, the face (ldEde adapter member where the holes open (the), has a circular flange (1g) suitably positioned relative to the arrangement of all the holes (le) so that said holes are located the inside of the collar which makes access to the holes (the) difficult in order to prevent malicious actions. This external collar (zig) is relatively thin.

De même, la face (Id) de l'organe adaptateur (1) présente en débordement, une portée centrale (lh) convenablement positionnée de façon à ce que l'ensemble des trous (le) se situe à l'extérieur de ladite portée (lh) (figure 3). Le royale de cette portée (lh) est, comme la collerette lg) et avantageusement en combinaison avec ladite collerette, de rendre difficile l'accès aux troues (le)o
Le bord périphérique (1h1) de cette portée (lh) est de plus très légèrement conique, sans pour cela exclure une conception cylindrique.
Similarly, the face (Id) of the adapter member (1) has an overhang, a central bearing (lh) suitably positioned so that all of the holes (le) is located outside of said bearing (1h) (figure 3). The royal of this litter (lh) is, like the flange lg) and advantageously in combination with said flange, to make access to the holes (the) difficult.
The peripheral edge (1h1) of this span (lh) is also very slightly conical, without excluding a cylindrical design.

L'organe d'entraSnement (2) présente en bout un dégagement (2d) qui donne passage avec un léger jeu à la portée (lh) lorsde l'engagement des doigts (6) dans les trous (le) de l'organe adaptateur (1) (figure 4). The drive member (2) has at the end a clearance (2d) which gives passage with a slight clearance to the range (lh) during the engagement of the fingers (6) in the holes (le) of the adapter member (1) (figure 4).

Les avantages ressortent bien de la description en particulier on souligne - La fonction importante de la collerette (lg) et de la portée (lh) qui rendent difficile l'accès aux trous (le) par des outils classiques autres que la clé d'entrainement (2) normalement prévue. The advantages emerge clearly from the description in particular it underlines - The important function of the flange (lg) and the range (lh) which make it difficult to access the holes (le) by conventional tools other than the drive key (2) normally expected.

L'Addition ne se limite aucunement à celui de ses modes d' application non plus qu'à ceux des modes de réalisation de ses diverses parties ayant plus spécialement été indiquées ; elle en embrasse au contraire toutes les variantes.  The Addition is in no way limited to that of its modes of application any more than to those of the embodiments of its various parts having been more especially indicated; on the contrary, it embraces all its variants.
