Curvilinear conveyor chain suitable for running along a guide comprising at least one curved section

A link of a curvilinear conveyor chain suitable for running along a guide comprising at least one curved section, said curved section comprising a pair of guide bodies spaced apart from each other and having respective side surfaces which are faced to each other and which define a curved path, wherein one of said lateral surfaces defines the inner side of said curved path and the other of said lateral surfaces defines the outer side of said curved path, wherein said link comprises:

• a plate body having:
• a first surface defining a support surface adapted to support products to be transported,
• below said first surface, a second surface substantially flat and defining at least one plane resting and sliding on at least one respective support surface of a raceway of straight sections of said guide,
• an articulation portion extending below said first surface of said plate body and substantially in the middle thereof, and comprising at least a pair of housings transverse to the travel direction (DS) of said conveyor chain along said guide and adapted to accommodate each a respective articulation pin of said link with similar links, respectively preceding and following, to form said conveyor chain,
• wherein said link has at least one substantially flat reaction surface (SR) extending below said first surface of said plate body in a plane transverse to the longitudinal axes (X-X) of said articulation pins and which, when said conveyor chain runs along said at least one curved section, is adapted to contact at least a portion of the lateral surface defining the inner side of said curved path to generate a radial reaction force (RR) acting on said link along a direction of action (DRR) extending above said longitudinal axes (X-X) of said articulation pins, wherein said reaction surface (SR) comprises at least one section extending above said second surface of said plate body interpenetrating it.
