Upon repeated actuation of the push button 50, the locking pin 38 is moved upward again due to the tensioned spring 49, as shown in Fig. 2.

Abstract

L'invention concerne une voiture à pousser, en particulier une poussette, pourvue de plusieurs roues (14, 18) montées sur un châssis (12) et pouvant tourner autour d'axes de rotation (26). Au moins une des roues (14, 18) est réalisée sous la forme d'une roue de guidage pivotante (24). La voiture à pousser présente en outre une unité d'immobilisation (36) destinée sélectivement à la libération et au blocage de cette aptitude au pivotement, pourvue d'un élément de blocage (40) et d'un élément de logement (44) présentant un logement d'élément de blocage (48). Ces éléments sont mobiles l'un par rapport à l'autre entre une position de blocage et une position de libération, par le fait qu'on amène l'élément de blocage (40) et/ou l'élément de logement (44) dans un état de précontrainte, dans lequel l'élément de blocage (40) peut être précontraint en direction de l'élément de logement (44) et/ou l'élément de logement (44) peut être précontraint en direction de l'élément de blocage (40), et dans lequel l'élément de blocage (40), lors d'un pivotement consécutif de la roue de guidage (24), s'enfonce automatiquement dans le logement d'élément de blocage (48) de l'élément de logement (44).
