Spring loaded vertical and horizontal self aligning roller chock

摘要

A self-aligning roller chock comprises a deck mounting structure which includes a boss member coupled to the deck and a swivel base plate rotationally coupled to the boss member for rotation about an axis substantially perpendicular to the deck; a pivot assembly coupled to the swivel base plate; a frame coupled to the pivot member and configured to pivot relative to the deck mounting member about the pivot assembly; and a sheave wheel rotationally mounted within the frame adapted to receive rigging line therein. The chock will pivot about two axes providing a self-aligning horizontal and vertical alignment with a resulting force of the rigging line. The self-aligning roller chock may further include a spring coupled to the frame and partially supporting the weight of the frame and the sheave wheel at least when the axis of the sheave wheel is non-parallel to the plane of the deck.

1. A self-aligning roller chock comprising:
A) A deck mounting structure configured to be secured to a deck; B) A pivot assembly coupled to the deck mounting structure; C) A frame coupled to the pivot member and configured to pivot relative to the deck mounting member about the pivot assembly; D) A sheave wheel rotationally mounted within the frame adapted to receive rigging line therein and wherein the frame and sheave wheel will pivot to provide a self-aligning vertical alignment with a resulting force of the rigging line; and E) A spring coupled to the frame and partially supporting the weight of the frame and the sheave wheel at least when the axis of the sheave wheel is non-parallel to the plane of the deck.
