<p>This cradle comprises an articulated metal framework being formed by an upper frame, four legs and a base structure. The cradle is characterised in that a shrouding is fitted to each of the four legs of the cradle, said shrouding being for each of said legs formed by a respective upright, rigid piece having an angular cross-section, a shrouding being upperly fitted between said upright, rigid pieces and being thereby applied on the four upper frame side members, this latter shrouding being for each of said side members made up by a respective semiflexible length having a generally prismatic cross-section. A cap is inferiorly and securely fitted to each of said upright shrouding pieces, at least two of said caps having a respective wheel fitted to each of them, said wheel not projecting from the cap base, this latter having an arcuately bevelled portion allowing the wheel to come into contact with the floor and to thus rest on it when the cradle's legs have been made to adopt an inclined position. <IMAGE></p> |
