RIGID CHAIN LINK AND RIGID CHAIN EQUIPPED WITH SUCH LINK

摘要

Link (200n) of rigid chain (100), comprising at least one cheek (1), of generally rectangular shape, of thickness (93, 97) substantially constant perpendicular to its main plane (81). The cheek (1) comprises a first portion (2) and a second portion (4). Each of the parts (2, 4) comprises: - a heel (5) arranged to bear against a corresponding heel of an analogous cheek (1n-1; ln + 1) of a link (200n-1; 200n + 1) adjacent to the rigid chain (100), and - a base (7) arranged to form a bearing about an axis (400) of rotation relative to said adjacent link (200n-1; 200n + 1) . The heel (5) and the base (7) extend respectively on one side and the other of the main plane (81) and parallel to said main plane (81).
