Title (EN) WET-FIT FASTENER
(FR) ÉLEMENT DE FIXATION À AJUSTEMENT PAR VOIE HUMIDE
Abstract:
(EN) The present invention is concerned with improvements to removable fasteners and is particularly related to removable and re-usable fasteners for use in wet-fit applications, such as joining components that include a sealant or adhesive. A dowelling fastener (200) is provided having a head end and an insertion end and a cylindrical dowelling portion, wherein the fastener is provided with a plunger (204) at the insertion end for clearing material from a hole as the fastener is inserted into the hole, wherein the plunger is rigid and has a circular cross section with a diameter substantially the same as the dowelling portion of the fastener, the plunger tip thereby being a close fit with the hole. The plunger of the present invention is intended specifically for clearing materials from the bore and therefore has other features optimised for this purpose, including ridges around its periphery.
(FR) La présente invention concerne des améliorations apportées à des éléments de fixation amovibles et concerne en particulier des éléments de fixation amovibles et réutilisables destinés à être utilisés dans des applications à ajustement par voie humide, telles que des composants d'assemblage qui comprennent un agent d'étanchéité ou un adhésif. Un élément de fixation par chevillage (200) comporte une extrémité de tête et une extrémité d'insertion et une partie de chevillage cylindrique, l'élément de fixation étant pourvu d'un piston (204) au niveau de l'extrémité d'insertion pour dégager le matériau d'un trou lorsque l'élément de fixation est inséré dans le trou, le piston étant rigide et présentant une section transversale circulaire dont le diamètre est sensiblement identique à celui de la partie de chevillage de l'élément de fixation, la pointe du piston étant ainsi étroitement ajustée avec le trou. Le piston selon la présente invention est destiné spécifiquement à dégager des matériaux de l'alésage et présente donc d'autres caractéristiques optimisées à cet effet, y compris des crêtes autour de sa périphérie.
