Description
DESCRIPTIFDESCRIPTION
La présente invention concerne un ensemble clef et vis ou écrou dans un montage très The present invention relates to a key and screw or nut assembly in a very
particulier pour éviter les vols de roue ou selle de vélo. particularly to prevent theft of a wheel or bicycle saddle.
Le montage de divers éléments composant un vélo s'effectue d'une manière traditionnelle par vis et écrou. Or la démontabilité d'éléments nobles tels que roue, selle... en utilisant des clefs classiques du commerce facilite le vol. L'ensemble selon l'invention permet de remédier à cet inconvénient. Il comporte en effet une bague libre en rotation entourant l'écrou ou la tête de vis. Une clef particulière et unique comprend des formes pour coopérer et entrer en contact avec des saillies et des creux disposés selon une configuration correspondante à un arrangement, à un code précis The various components of a bicycle are assembled in the traditional way using screws and nuts. However the dismantling of noble elements such as wheel, saddle ... using conventional commercial keys facilitates theft. The assembly according to the invention overcomes this drawback. It indeed comprises a free rotating ring surrounding the nut or the screw head. A particular and unique key includes forms for cooperating and coming into contact with projections and recesses arranged in a configuration corresponding to an arrangement, to a specific code.
l o qui autorise seul le vissage ou le dévissage. l o which only authorizes screwing or unscrewing.
Pour cela, des ergots équipent l'intérieur de la bague, des cannelures et encoches équipent l'écrou ou la tête de vis. Ces divers équipements donnent trois niveaux de combinaisons par For this, lugs equip the inside of the ring, grooves and notches equip the nut or the screw head. These various equipments give three levels of combinations per
leurs nombres, leurs formes, leurs positions et orientations. their numbers, shapes, positions and orientations.
Un exemple de réalisation est donné par les dessins suivants: I 5 La figure 1 représente la bague de l'ensemble La figure 2 représente l'écrou La figure 3 représente l'écrou monté et équipé de sa bague La figure 4 représente la clef La figure 5 représente les ergots sur la bague An example of embodiment is given by the following drawings: I 5 FIG. 1 represents the ring of the assembly FIG. 2 represents the nut FIG. 3 represents the nut assembled and fitted with its ring FIG. 4 represents the key La Figure 5 shows the pins on the ring
2 o Les figures 6 et 7 représentent les cannelures et encoches sur l'écrou. 2 o Figures 6 and 7 show the grooves and notches on the nut.
Le montage de l'écrou (2) sur la vis (11) suivant la figure 3 bloque un élément (12). The mounting of the nut (2) on the screw (11) according to Figure 3 blocks an element (12).
L'écrou est entouré d'une bague (3) rigide indéformable, libre en rotation mais piégée par un épaulement (10) situé sur l'embase de l'écrou. La bague est dotée d'ergots (4) suivant les figures 1 et 5. Ces ergots sont construits et choisis en nombre, en forme, en position et orientation. Ils permettent un premier niveau d'introduction de la clef (1) (Fig. 4) qui The nut is surrounded by a rigid non-deformable ring (3), free to rotate but trapped by a shoulder (10) located on the base of the nut. The ring is provided with lugs (4) according to FIGS. 1 and 5. These lugs are constructed and chosen in number, shape, position and orientation. They allow a first level of introduction of the key (1) (Fig. 4) which
comprend sur son pourtour extérieur des encoches appropriées (7). includes on its outer periphery appropriate notches (7).
L'écrou (2) comporte des rainures (13) en correspondance avec les ergots (4) pour être emboîté dans la bague (3). A mi-épaisseur l'écrou comporte sur son pourtour (Fig. 2 et 6) des cannelures (5) qui représentent le deuxième niveau d'introduction de la clef (1) qui The nut (2) has grooves (13) in correspondence with the lugs (4) to be fitted into the ring (3). At mid-thickness the nut has on its periphery (Fig. 2 and 6) grooves (5) which represent the second level of introduction of the key (1) which
3 0 comprend sur son pourtour intérieur des cannelures femelles (8) appropriées (Fig. 4). 3 0 includes on its inner periphery appropriate female grooves (8) (Fig. 4).
Ces cannelures sont construites et choisies en nombres, en formes, en positions et orientations. These grooves are constructed and chosen in numbers, shapes, positions and orientations.
C'est ainsi que la figure 6 présente des cannelures plus ou moins régulières. This is how Figure 6 presents more or less regular grooves.
- 2 Sur sa partie supérieure, l'écrou (2) est doté d'encoches (6) (Fig. 7) . Elles définissent le troisième et dernier niveau d'introduction de la clef (1) qui comprend sur le fond de sa - 2 On its upper part, the nut (2) is provided with notches (6) (Fig. 7). They define the third and last level of introduction of the key (1) which comprises on the bottom of its
cavité des saillies (9) en correspondance avec les encoches de l'écrou. projection cavity (9) in correspondence with the notches of the nut.
Les trois niveaux d'introduction de la clef sur l'écrou sont représentés par des ergots (4) puis les cannelures (5) et enfin les encoches (6). Ils représentent à eux seuls une infinité de The three levels of introduction of the key on the nut are represented by lugs (4) then the grooves (5) and finally the notches (6). They alone represent an infinity of
combinaisons ce qui autorise à dire qu'une seule clef peut former un ensemble anti-vol. combinations which allows us to say that a single key can form an anti-theft unit.
L'ensemble selon l'invention est particulièrement destiné à protéger du vol les divers équipements de vélo mais aussi, et d'une façon générale, tout équipement de véhicule The assembly according to the invention is particularly intended to protect the various bicycle equipment from theft but also, and in general, any vehicle equipment
monté par vis écrou.mounted by screw nut.
