<p>1. Loading device for a vehicle, of the tail-lift type, comprising - a fixed upright (1), - a telescopic upright (2), one end of which is articulated on the fixed upright so that it can pivot between a first, folded position, to which the gravitational forces tend to bring it back, and a second, unfolded position, - a platform (3) articulated on the other end of the telescopic upright (2), the platform being able to move between a first, folded position and a second, unfolded position, in which it is approximately horizontal, the platform being kept in its second position, under the action of gravity, by interaction with a first abutment (8) on the telescopic upright (2), and - a level (4) which can move between a first, folded position, in which the telescopic upright (2) can adopt its first position under the action of gravity, and a second, blocking position, in which it is pushed back and held by the telescopic upright (2) which then occupies its second position, the movement of the lever (4) beyond its second position being prohibited by a second abutment (7) fixed to one of the uprights, the said loading device being characterized in that - the level (4) is in a single piece, it delimits a cam surface and it has one end articulated on one of the uprights and the other end forming a sliding surface on the other upright, so that the lever tends to adopt its second position under the action of gravity, and - the platform (3) carries a cam follower (5) intended to interact with the cam surface of the lever (4) so that, when the platform (3) moves from its second to its first position, the follower (5) pushes back the lever (4) from its second to its first position.</p> |
