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.
Claims17
A link of a rigid chain, comprising at least one flange of generally rectangular shape and of substantially constant thickness perpendicular to a main plane of the flange on a surface of the flange, the flange comprising a first part and a second part, each of the parts comprising:
- a heel having a surface configured to bear against a surface of a heel of a flange of an adjacent link of the rigid chain, and
- a base forming a bearing having a rotation axis of said link and said adjacent link extending perpendicular to the main plane through a central axis of the base,
- the heel and the base lying on respective opposite sides of the main plane and parallel to said main plane,
- wherein the heel of the first part and the heel of the second part both lie on one side of the main plane whilst the base of the first part and the base of the second part both lie on the opposite side of the main plane.
A link of a rigid chain, comprising at least one flange of generally rectangular shape and of substantially constant thickness perpendicular to a main plane of the flange on a surface of the flange, the flange comprising a first part and a second part, each of the parts comprising:
- a heel having a surface configured to come to bear against a surface of a heel of a flange of an adjacent link of the rigid chain, and
- a base forming a bearing having a rotation axis of said link and said adjacent link extending perpendicular to the main plane through a central axis of the base,
- the heel and the base lying on respective opposite sides of the main plane and parallel to said main plane,
- wherein the base of the first part and the base of the second part are substantially symmetrical with respect to one another relative to a central transverse plane perpendicular to the main plane.
A link of a rigid chain, comprising at least one flange of generally rectangular shape and of substantially constant thickness perpendicular to a main plane of the flange on a surface of the flange, the flange comprising a first part and a second part, each of the parts comprising:
- a heel having a surface configured to come to bear against a surface of a heel of a flange of an adjacent link of the rigid chain, and
- a base forming a bearing having a rotation axis of said link and said adjacent link extending perpendicular to the main plane through a central axis of the base,
- the heel and the base lying on respective opposite sides of the main plane and parallel to said main plane,
- wherein the flange bears lateral surfaces oriented so as to limit the relative rotation of the link and said adjacent link by abutting against lateral surfaces of said adjacent link, and
- wherein the flange further comprises a nipple on the same side of the main plane as the bases, the heels featuring one of said lateral surfaces, the nipple bearing another of said lateral surfaces, so that the lateral surface of the heel comes to abut against the corresponding lateral surface of the nipple of said adjacent link and the lateral surface of the nipple comes to abut against the corresponding lateral surface of the heel of said adjacent link.
