Abstract: An adjustable highchair, comprising a seat which is associated with a frame by virtue of seat position adjustment elements, characterized in that the seat position adjustment elements comprise actuation elements which are arranged in an upward region of the seat which can be accessed easily.

Abstract: An articulation for folding frames comprising a hollow internal support, which is adapted to support the ends of respective rods which are pivoted to the internal support in two spaced points, and a pair of bar-like elements, each being provided with a first end pivoted to a respective rod and a second end pivoted to a pivot; the pivot being slideable in a slot formed in the internal support and being fixed to an external support which is movable with respect to the internal support so as to define at least two positions: an open position, in which the rods form an angle with respect to each other, and a closed position, in which the rods are folded and substantially parallel.

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.
