Abstract

L'invention concerne un dispositif de freinage et d'immobilisation destiné à un châssis d'un chariot roulant (10), par exemple une poussette, comportant un frein à tambour (26) et une poignée d'actionnement de frein (20) qui sert à déplacer un élément de commande (60) du frein à tambour (26). La mâchoire (44) du frein à tambour (26) peut être déplacée d'une position médiane dans une première direction allant radialement vers l'extérieur jusqu'à une position de freinage pour le contact par frottement d'une surface de frottement (54) avec la surface circonférentielle intérieure (50) de la paroi de tambour (40) et dans une seconde direction, opposée à la première, jusqu'à une position d'immobilisation dans laquelle une denture intérieure (76) de la mâchoire qui peut venir en prise avec la denture extérieure (80) d'un élément de blocage (42) pour verrouiller l'élément de blocage (42) provoque l'immobilisation.
