Abstract

Le problème décrit par la présente invention est de permettre le stockage/le transport pratique d'une table, une vitrine, etc. lorsqu'elle n'est pas utilisée, par le retrait rapide des montants de son plateau et/ou de son socle. La solution selon la présente invention porte sur une structure de montant dans laquelle une pièce mobile en rotation est insérée dans une pièce fixe, une base configurant la pièce fixe étant fixée au plateau et/ou au socle, une saillie de blocage cylindrique courte faisant saillie depuis la base, un trou d'insertion étant percé dans la face inférieure de la saillie de blocage et des surfaces hélicoïdales qui sont légèrement en pente étant formées sur les deux côtés du trou d'insertion ; dans le même temps, la pièce mobile est fixée sur l'extrémité du montant, une plaque en croix est réalisée pour établir un pont sur le montant dans la direction du diamètre presque à son extrémité, et une tige de blocage en forme de T est prévue pour être située sensiblement au centre de la plaque en croix ; et en insérant la saillie de blocage de la pièce fixe dans la circonférence interne du montant de la pièce mobile en rotation tout en insérant la tige de fixation de la tige de blocage en forme de T dans le trou d'insertion de la face inférieure et en tournant le montant autour de l'axe, la tige de fixation est serrée sur la surface hélicoïdale tandis que la pièce mobile en rotation est fixée à la pièce fixe. Des rainures sont prévues sur la surface hélicoïdale à intervalles angulaires égaux selon un modèle de rayonnement.
