Abstract

L’invention concerne une structure de rétraction pour rail coulissant, qui comprend un rail fixe (1), un rail escamotable (3) et une unité de rétraction (300). L’unité de rétraction comprend un élément guide (8), un élément fixe (4), un rail coulissant (5), une glissière (20), un élément crochet (30) et un élément élastique (6). Le rail coulissant comporte deux rails (13, 14) placés bout à bout, et deux fentes (15) de crochet sont formées sur les extrémités avant de deux rails placés bout à bout. L’élément crochet est placé sur le rail coulissant, et une partie rotative (31) de l’élément crochet est placée sur une partie (21) d’axe rotatif de la glissière. Dans une autre forme de réalisation, la partie (41) d’axe rotatif de l’élément crochet est prévue sur le rail (100) d’axe rotatif du rail coulissant, et les deux rails placés bout à bout du rail coulissant sont placés de part et d’autre de la partie rotative ou de la partie d’axe rotatif de l’élément crochet. En situation de rétraction, l’élément crochet est dans une phase de contrainte en raison de la force de traction de l’élément élastique, de sorte que l’élément crochet produit un effet de mise en about permettant à la structure rétractable de rail coulissant de former un assemblage bout à bout stable. Les deux forces d’aboutement appliquées sur l’élément crochet par le rail escamotable sont transmises aux deux rails placés bout à bout, de sorte que l’élément crochet peut glisser de manière stable le long du rail coulissant, tourner sans à-coup quand il atteint la fente de crochet et être fixé de manière stable dans les deux fentes de crochet.
