ABSTRACT:
The framework, particularly for folding cots, includes an upper frame having a pair of longitudinal members and a pair of cross-members which are pivoted to corner joints and which can be folded in a median portion. Corner legs are associated with the corner joints, and the cover legs are articulated to a lower frame which is substantially H-shaped and which include rods which are articulated proximate to the lower end of the legs at one of their ends and which are connected in pairs to the ends of the central portion of the H-shaped frame at their other end. The central portion has a first lower connecting joint and a second lower connecting joint, each of which is articulated to the end of connecting rods which are articulated to a central plate at their other end.
