A cradle includes first and second frames in the form of an inverted "U", the
legs
thereof crisscrossing and being connected to one another by sliding clamps in the
crisscrossing point. Above the crisscrossing points, the structure has a third
frame supporting a basket. The third frame is hinged to opposite points of the
legs of the second frame and linked to the first frame so that altogether there
are at least three connecting points between the first, second and third frames.
An element adjustably joining both parts of the first and second frames is provided
beneath the crisscrossing points, the element fixing the degree of opening between
the frames thereby regulating the height of the basket.
