ABSTRACT:
In an extensible arm having a reticular lattice structure with a polygonal cross-section, particularly for space modules or vehicles, each longitudinal side of the lattice structure includes first and second kinematic pantograph chains each constituted by a plurality of rods articulated together so as to define a series of aligned X-shaped elements. The rods of the second kinematic chain are shorter than the rods of the first kinematic chain, and the articulations between the X-shaped elements of the second kinematic chain located on one side of the latter coincide with the articulations between the X-shaped elements of the first kinematic chain located on the same side. This lattice structure can adopt any configuration between a fully retracted configuration in which the kinematic chains constituting the structure are all closely packed, and a fully extended configuration in which the rods of the X-shaped elements of the second kinematic chain are substantially parallel to each other so as to define straight struts in correspondence with the vertices of the section of the lattice structure. The rods of the X-shaped elements of the first kinematic chain, however, are disposed as diagonals connecting the struts. The articulated connections between the rods of the first and second kinematic chains are constituted by rotary couplings.
