Title: Flexible rigging
IPC: B63B15/02
Filed: 1984-04-19
Abstract: The invention relates to a process for eliminating the play of mechanical connections and the slack of the ropes of the rigging of the masts of vessels in order to avoid dismasting. It is characterised by the addition of a spring 3, 5 on each shroud of the rigging. When the mast 1 is stressed by the force F, the triangle ABC is deformed, AC extends, the spring 3 supporting this extension. The triangle ABD is deformed, AD shortens, and the spring 5 absorbs this shortening. When the force F is reversed to become F', the movement of the springs 3, 5 is reversed, but the shrouds 2, 4 remain taut and their mechanical connections without play. The mast can be installed on a spherical articulation 6 or pivot bearing 7. The process according to the invention is intended in particular for equipping the rigging of masts of all types of vessels.
