ABSTRACT:
A vehicle-mounted device for positioning traffic cones (14) on the street and for collecting them from the street. Each cone has a conical hollow body (15) and a base (16). The cones are stacked and nested in a supply (8) comprising a hollow vertical body open at least at its base (28) to permit the reception of the base (16) of a cone. A platform (4) is disposed about a vertical axis (10) and disposed below the base (28) of the supply (8). The platform (4) has at least one opening (6) and a fork formed of two fingers (7) which are substantially horizontal and are spaced from each other in a direction radially of the platform so as to let pass only the body (15) of a cone and not the base (16) of the cone. These fingers are disposed at a height (H) above the platform (4) at least equal to the thickness of the base (16) of a cone such that in the course of movement of the supply (8) and the platform (4) relative to each other in rotation about the vertical axis (10) in a direction such that the fingers of the fork enter the stack of cones contained in the supply, the opening (28) of the supply will pass above the opening (6) provided in the platform (4) and the fingers (7) of the fork will penetrate between the bases (16) of the last cone (14) of the stack in the supply and the next-to-last cone, thereby detaching from the stack during such relative displacement the last cone which then descends to the street and retaining the next-to-last cone. Much the same structure can be used during collection of the cones from the street.
