(EN) RETRACTABLE FIXATION DEVICE
(FR) DISPOSITIF RETRACTABLE DE FIXATION
Abstract
(EN)
A fastener (10) for securing two members (3, 4) together through an aligned bore (4) in the two members (3, 4), the fastener comprising a longitudinally extending body (12) having at least one opening (14, 16) adjacent each of respective ends thereof, the body having a central bore hole, a threaded shaft (22) concentrically disposed in the central bore hole and having opposite threads (23A, 24A) at each end, with a rotation applying member (25) at an accessible end, a nut (27, 28) provided on each of the opposite threads (23A, 24A) in threaded engagement with the respective thread, at least one longitudinally extending engaging finger attached to each of the nuts and disposed adjacent a respective one of the openings (14, 16), the fingers (18, 20) being adapted to extend through the respective opening (14, 16) when the shaft (22) is turned in a first direction to cause the nuts (27, 28) to move toward each other, thereby causing the fingers (18, 20) to engage, when the openings (14, 16) at each end are disposed in the aligned bore (4) adjacent different ones of said two members (1, 3) to be secured together, with respective ones of said two members (1, 3), thereby securing the two members (1, 3) together.
(FR)
L'invention porte sur une fixation (10) destinée à assembler deux éléments (3, 4) au moyen d'alésages alignés (4) pratiqués dans lesdits éléments (3, 4). La fixation comprend: un corps oblong (12) présentant au moins une ouverture (14, 16) proche de chacune de ses extrémités, un alésage central, un axe fileté (22) se plaçant dans l'alésage central dont les extrémités opposées sont filetées dans des sens opposés (23A, 24A) et dont l'extrémité accessible est munie d'un élément (25) permettant de transmettre une force de rotation; deux écrous (27, 28) engagés sur leur filetage respectif (23A, 24A); au moins un doigt longitudinal d'ancrage solidaire de chacun des écrous et contigu à son ouverture respective (14, 16) et conçu pour s'engager lors du vissage dans l'ouverture (14, 16) de son côté respectif, les doigts (18, 20) étant conçus pour se déployer dans leur ouverture respective (14, 16) lorsqu'on fait tourner l'axe dans un premier sens, ce qui rapproche les écrous (27, 28) et met les doigts (18, 20) en contact avec leurs éléments respectifs (1, 3) qui se trouvent ainsi ancrés l'un à l'autre, les ouvertures (14, 16) pratiquées à chacune des extrémités ayant auparavant été placées dans les alésages alignés (4).
