Patent

CA 2516052

A blind fastener for insertion through an aperture in a workpiece, the fastener comprising a pin (11), a sleeve (21) and an abutment member (32); the pin (11) extending inside the sleeve (21) and engaging therewith at or near a first end (24) of the sleeve; the sleeve having a radially expandable portion; the abutment member (32) being adjacent the second end (25) of the sleeve and projecting radially therefrom and the pin (11) extending beyond the abutment member (32); in which the abutment member is removably secured to the sleeve by means sufficiently strong to allow handling of the assembled fastener to be inserted in the aperture in the workpiece and installed therein, but sufficiently weak to allow the abutment member to be removed from the sleeve so that the pin and sleeve can be forced out of the aperture on the workpiece, to remove the fastener therefrom.

L'invention concerne un rivet aveugle destiné à être introduit dans une ouverture d'une pièce, comprenant une cheville (11), une enveloppe (21) et un élément de butée (32). La cheville (11) est située à l'intérieur de l'enveloppe (21) et entre en prise avec cette dernière à proximité ou au niveau d'une première extrémité (24) de l'enveloppe. L'enveloppe comporte une partie avec une collerette. L'élément de butée (32) est situé à proximité de la seconde extrémité (25) de l'enveloppe et forme une projection radiale. La cheville (11) dépasse l'élément de butée (32). L'élément de butée est fixé de façon amovible à l'enveloppe par un moyen suffisamment solide pour que le rivet assemblé puisse être introduit et mis en place dans l'ouverture de la pièce, mais suffisamment fragile pour que l'élément de butée puisse être retiré de l'enveloppe pour que la cheville et l'enveloppe puissent être sortis avec force de l'ouverture de la pièce, pour retirer le rivet.
