<p>Of the type that are coupled together by socketing without resorting to the use of articulation rods or axes between links, where one of the longitudinal edges is equipped with a series of socketed pieces (3), in the form of a hook, where there are seating devices (5) whose interior noticeably exceeds the semi-cylinder and that are segmented by means of an intermediate partition (6) for strengthening purposes, which has a flat edge included on the imaginary plane of the mouth of those seating devices (5), whereas the protruding pieces (4) take the form of a pair of coaxial and opposite pivots (8), equipped with one single flat side (9) that facilitates access to the seating devices (5) for the assembly between links and that is coplanar with the edge (7) of the partitions (6) when the chain is working in a normal situation. It is thus possible to make the socketed pieces (3) rigid thanks to the partitions (6), in view of the fact that it is not necessary to deform the mouth of the seating devices (5) to insert the pivots (8) of the protruding pieces into them.</p> |
