CA 2547309
A fastener system includes a screw (4) or bolt having two interleaved helical threads (5a, 5b), which bracket a helicoil (1). The helicoil expands and torques by various means to maintain hold and purchase between the screw coil combination and the substrate (9) into which the screw and helicoil are inserted even when the substrate recedes a significant distance from the screw and helicoil combination. The fastener system includes means for latching the tilt of the coil so as to minimize the constraining forces and optimize the motion of the helicoil, that results in the screw or bolt being pushed into the substrate.
Un système de fixation comprend une vis (4) ou un boulon muni de deux filetages hélicoïdaux entrelacés (5a, 5b) qui encadrent un Helicoil (1). L'Helicoil se dilate et fournit un couple de façon à maintenir la prise et l'appui entre une combinaison de spirale de vis et un substrat (9) dans lequel on insère la vis et l'Helicoil, même si le substrat est considérablement éloigné de la combinaison de vis et d'Helicoil. Le système de fixation comprend des moyens pour bloquer l'inclinaison de la spirale de façon à réduire au minimum la contrainte et à assurer un mouvement optimal de l'Helicoil, qui permet à la vis ou au boulon de s'enfoncer dans le substrat.
