Patent

CA 2442707

A self-contained assembled fastener (11) includes a retainer (15), a through- pin (24) assemled to an over-molded knob (13), a rubber sleeve (17), and an end cap (19). The retainer (15) includes a radially disposed upward-facing cam ramp (26) that cooperates with a like cam ramp (29) on the knob (13) affixed to the pin (24). To secure two panels (12, 14) the retainer base is first fastened to a first panel preferably by clinch-type attachment (16) with the center pin extending through the retainer and through the two panels to be attached to the opposite side of the second panel. The rubber sleeve (17) is slidably fitted around the end of the pin (24) and is retained axially by an end cap (19). When the pin is turned, the cam-action between the pin ramp and the retainer ramp withdraws the pin axially upward from the retainer compressing the rubber sleeve and causing it to bulge against the backside of the second panel.

L'invention concerne une attache (11) assemblée autonome comprenant un dispositif de retenue (15), une broche traversante (24) associée à un bouton surmoulé (13), un manchon en caoutchouc (17) et un bouchon d'extrémité (19). Le dispositif de retenue (15) comporte une rampe de cames (26) tournée vers le haut, disposée radialement, qui coopère avec une rampe de cames (29) analogue disposée sur le bouton (13) fixé sur la broche (24). Pour fixer deux panneaux (12, 14), la base du dispositif de retenue est d'abord attachée à un premier panneau, de préférence par un type de fixation à river (16) avec la broche centrale s'étendant à travers le dispositif de retenue et à travers les panneaux à attacher au côté opposé du deuxième panneau. Le manchon en caoutchouc (17) est ajusté coulissant autour de l'extrémité de la broche (24) et retenu axialement par un bouchon d'extrémité (19). Lorsque la broche tourne, l'action des cames entre la rampe de broche et le rampe du dispositif de retenue retire la broche axialement vers le haut, à partir du dispositif de retenue, comprimant le manchon en caoutchouc et le faisant gonfler contre l'envers du deuxième panneau.
