Title (EN) VARIABLE ATTACHING DEVICE
(FR) ATTACHE VARIABLE
Abstract:
(EN) An attaching device and more particularly a variable attaching device is disclosed. An attaching device (figure 1) comprises an active element (1), a male element (7), an intermediate part (8) and a screw (9) comprising a separating pivot (12). Such an attaching device is operational owing to the action of the separating pivot (12) upon the segments (3, 4), of the active element, these acting against the walls of the male element (7). It is semi-removable in the sense that it can only be removed after extracting the screw (9). Such an attaching device can be made removable by simply cutting and removing the removable pivot (12) from the screw (9) and replacing the screw (9). The invention may find a number of applications, particularly in the field of dental prosthesis or in the mechanical field (chains, joints).
(FR) La presente invention a trait au domaine technique des attaches et plus particulierement a celui des attaches variables. Soit une attache telle que representee a la fig. 1 composee d"un element actif (1), d"un element male (7), d"une piece intermediaire (8) et d"une vis (9) comportant un pivot ecarteur (12). Une telle attache est fonctionnelle grace a l"action du pivot ecarteur (12) sur les segments (3, 4), de l"element actif, ceux-ci agissant contre les parois de l"element male. Elle est semi-amovible dans la mesure ou elle ne peut etre defaite que par le retrait de la vis (9). L"attache predecrite peut etre rendue amovible par le simple fait de sectionner et d"enlever le pivot amovible (12) de la vis (9) et de remettre cette derniere en place. La presente invention peut certainement trouver de nombreux cas d"application, notamment dans le domaine de la prothese dentaire ou en mecanique (chaines, articulations).
