Abstract
Description
DESCRIPTIOIN
La présente invention se rapporte d1une façon générale å la réalisation de mesures de périmètres extérieurs sur des volutes solides présentant une extrémité libre.DESCRIPTION
The present invention relates generally to the realization of measurements of external perimeters on solid scrolls having a free end.
I1 est usuel par exemple en art dentaire,d'utiliser un dentimètre pour la prise du périmètre des préparations. It is customary, for example in dentistry, to use a dentimeter for taking the perimeter of the preparations.
Ce mode opératoire présente l'inconvénient d'obliger l'opérateur à enfiler un fil,habituellement métallique, par deux trous ménagés dans un manche support et ce pour réaliser une boucle arbitraire fixée par enroulement autour du manche.This procedure has the drawback of forcing the operator to thread a wire, usually metallic, through two holes in a support handle, in order to produce an arbitrary loop fixed by winding around the handle.
Ce procédé est long, délicat et peu pratique.This process is long, delicate and impractical.
Le dispositif suivant 11 invention permet d'éviter ces inconvénients.The device according to the invention avoids these drawbacks.
L'invention est matérialisée,suivant l'un de ses aspects,par un
support faisant office de manche de préhension.The invention is embodied, according to one of its aspects, by a
support acting as grip handle.
Dans ce support est enchassé à l'origine une boucle préfabriquée
en fil souple.In this support is originally encased a prefabricated loop
in flexible wire.
Suivant une particularité judicieuse, le fil à périmctre peut se torsader hors du manche ou dans le manche sans risque de rupture au serrage.According to a judicious feature, the perimeter wire can be twisted out of the handle or into the handle without risk of breaking when tightened.
Par une autre caractéristique ce dispositif est présenté sous forme de diamètres progressifs préalablements déterminés à la fabrication à partir d'un porte bague étalon.By another characteristic, this device is presented in the form of progressive diameters previously determined during manufacture from a standard ring holder.
Ce qui évite la réalisation extemporannée de boucles à diamètre incert
Le dispositif objet de l'invention peut aisément hêtre dapté sur tout
support habituel,que ce soit une pince ou que ce soit sur des manches This avoids the extemporaneous realization of loops with uncertain diameter
The device which is the subject of the invention can easily be adapted to any
usual support, whether pliers or on sleeves
