Marking device support on pivotable cradle carried by trolley

A device for the marking of a surface including:

• a supporting chassis,
• marking means including a marking implement designed to create a point or a mark on said surface, and
• means for movement of the marking implement parallel to a first and a second plane of motion, said planes being perpendicular to each other and to the surface to be marked, in order to create two-dimensional symbols on the surface to be marked within a marking window, where the movement of the marking implement parallel to said first plane of motion is effected by at least one rotation of the marking implement around an axis parallel to said second plane of motion,
• wherein the means for moving the marking implement include at least:
• a linear guidance rail connected to the chassis and a trolley fitted to said rail to be mobile in linear motion in a direction parallel to said second plane of motion and to the surface to be marked,
• motor means for driving the trolley in linear movement in both directions along the linear guidance rail,
• an oscillating cradle, which is connected to the trolley on a face that is oriented toward the surface to be marked to pivot in relation to the trolley on said axis parallel to said second plane of motion, and which supports the marking implement opposite to the trolley,
• and motor means for the movement in rotation, in both directions, of the cradle on said axis parallel to said second plane of motion, and which include at least one arm, having first and second ends, the first end being connected to the cradle, and the second end being located opposite to the first end and equipped with a toothed sector engaging a sprocket wheel that is driven in rotation by a motor.
