A collapsible wheelbarrow includes a rigid front bracket, a wheel rotatably secured to the front bracket, and first and second handle arms pivotably attached to the front bracket. The first and second handle arms are laterally pivotable about first and second pivot axes respectively. The first and second pivot axes are each spaced apart from the axis of rotation of the wheel. Preferably a clamping device removably applies a clamping force between the first and second handle arms and clamps a rigid tray between the first and second handle arms. The tray is preferably interconnected with the first and second handle arms to permit relative movement in a lateral direction and to prevent relative movement in a forward rearward direction. Preferably, the front bracket has spaced apart upper and lower walls and the first and second handle arms extend between the upper and lower walls.

L'invention concerne une brouette pliable comprenant un support avant rigide, une roue fixée rotative au support avant ainsi que des premier et second bras à poignée fixés pivotants sur le support avant. Les premier et second bras à poignée sont pivotants latéralement autour de premier et second axes de pivot respectivement. Les premier et second axes de pivot sont espacés chacun de l'axe de rotation de la roue. De préférence, un dispositif de serrage applique de façon réversible une force de serrage entre les premier et second bras à poignée et il serre un plateau rigide entre les premier et second bras à poignée. Le plateau est de préférence relié aux premier et second bras à poignée pour permettre un mouvement relatif dans une direction latérale et pour empêcher le mouvement relatif dans une direction avant arrière. De préférence, le support avant présente des parois supérieure et inférieure espacées et les premier et second bras à poignée s'étendent entre les parois supérieure et inférieure.
