Abstract

L'invention concerne une serrure pour échafaudage destiné à sécuriser une liaison embrochée (11) entre deux éléments structuraux d'échafaudage (13, 13') qui forment ensemble un conduit de passage (15), comprenant un goujon (17) destiné à être inséré dans le conduit de passage (15) et un dispositif de fermeture (19) destiné à bloquer le goujon (17) inséré dans le conduit de passage (15). Le goujon possède une portion de butée (21) à une première extrémité et une portion d'insertion (23) munie d'un retrait de verrouillage (25) à une deuxième extrémité. Le dispositif de fermeture (19) possède un corps de serrure (27, 127, 227) muni d'un conduit d'insertion de goujon (29) et d'une cavité réceptacle de cylindre (31). Un cylindre de fermeture (47, 147, 247) muni d'un élément de verrouillage (33, 71, 133) se loge dans la cavité réceptacle de cylindre (31). L'élément de verrouillage (33, 71, 133) peut être déplacé au choix entre une position de libération, dans laquelle l'élément de verrouillage (33, 71, 133) libère le conduit d'insertion de goujon (29) du corps de serrure (27, 127, 227) pour une insertion ou un retrait de la portion d'insertion (23) du goujon (17), et une position de verrouillage, dans laquelle l'élément de verrouillage (33, 71, 133) vient en prise dans le conduit d'insertion de goujon (29) du corps de serrure (27, 127, 227) et verrouille la portion d'insertion (23) du goujon (17) au niveau du retrait de verrouillage (25) lorsque la portion d'insertion (23) du goujon (17) est insérée dans le conduit d'insertion de goujon (29) du corps de serrure (27, 127, 227).
