Abstract
Link for a rigid chain, comprising at least one flange, of rectangular overall shape, with a substantially constant thickness perpendicularly to its main plane. The flange comprises a first part and a second part. Each of the parts comprises a heel designed to bear against a corresponding heel of a similar flange of an adjacent link of the rigid chain, and a base designed to form a bearing about a rotary pin with respect to said adjacent link. The heel and the base each extend on either side of the main plane and parallel to said main plane.
Claims13
A rigid chain formed by assembling links one after the other, each link of the rigid chain comprising at least one flange, of rectangular general shape, of substantially constant thickness perpendicular to its main plane, the flange comprising a first part and a second part, each of the first and second parts comprising:
- a heel adapted to come to bear against a corresponding heel of an analogous flange of an analogous link of the rigid chain, two analogous links having longitudinally aligned flanges, each heel bearing a front surface oriented so as to come to bear against a corresponding surface of said analogous link, the front surface and the longitudinal edge surface being substantially perpendicular, the front surface being substantially continuous, planar and perpendicular to a transverse direction, and
- a base adapted to form a bearing around a rotation axis relative to an adjacent link,
- the heel and the base lying on respective opposite sides of the main plane and parallel to said main plane.
