Title
(EN) FACILITATED TIGHTENING DEVICE
(FR) DISPOSITIF DE SERRAGE A EFFET FACILITE
Abstract
(EN)
A facilitated tightening device allowing a bolt to be inserted smoothly by preventing a screw block engaged with the bolt from being inclined or fallen down, comprising a base (2) having a bolt insert hole (7) partly forming a bolt receiving surface (9) and an inclined surface (8) gradually decreasing in diameter toward the insert side of the bolt (6) in the state of being continued with the bolt insert hole (7) formed therein, a screw block (3) slid along the inclined surface (8) according to the axial movement of the inserted bolt (6) to be engaged with the bolt (6), an energizing member (5) energizing the screw block (3) in inner radial direction, and guide means (10, 11) engaged with the screw block (3) to prevent the screw block (3) from being fallen down in the base (2).
(FR)
L'invention concerne un dispositif de serrage à effet facilité, permettant d'introduire une cheville avec aisance, de manière à éviter que le support fileté en prise avec ladite cheville ne soit incliné ou ne tombe. Ce dispositif comprend une base (2) présentant un trou d'insertion de la cheville (7) formant en partie une surface de réception de la cheville (9) et une surface inclinée (8) dont le diamètre diminue progressivement en direction de la face d'insertion de la cheville (6), jusqu'à se trouver prolongé par le trou d'insertion de la cheville (7) formé dedans. Ledit dispositif comprend en outre un support fileté (3) coulissant le long de la surface inclinée (8) selon le mouvement axial de la cheville (6) introduite et devant se trouver en prise avec ladite cheville (6), un élément d'énergisation (5) énergisant le support fileté (3) dans un sens radial intérieur, ainsi que des éléments de guidage (10, 11) en prise avec le support fileté (3) afin d'éviter qu'il ne tombe dans la base (2).
