Abstract
A bearing for a sail furling apparatus includes a spherical body having a longitudinal axis and containing a cylindrical longitudinal through-opening for receiving a cable of the furling apparatus. The body is freely rotatable on the cable and protects the furled sail from abrasive contact with the cable. The body contains a plurality of spaced longitudinal channels in the outer surface to define a plurality of spaced flutes to further space the furled sail from the cable and to facilitate smooth furling and unfurling of the sail.
Claims
exact text as granted — not AI-modified1 - 10 . (canceled)
11 . A bearing for a sail furling apparatus, comprising a body having a longitudinal axis, said body containing a cylindrical longitudinal through-opening for receiving a cable of the sail furling apparatus, said body being freely rotatable relative to the cable.
12 . A bearing as defined in claim 11 , wherein said body has a generally spherical configuration.
13 . A bearing as defined in claim 12 , wherein said bearing contains a plurality of spaced grooves in an outer surface, said grooves extending parallel to said longitudinal axis to define a plurality of flutes on said bearing outer surface.
14 . A bearing as defined in claim 13 , wherein said grooves are equally spaced around the circumference of said bearing.
15 . A bearing as defined in claim 14 , wherein said bearing includes flat top and bottom surfaces perpendicular to said longitudinal axis, whereby when a plurality of said bearings are arranged adjacent to each other on a cable of the sail furling apparatus, said top and bottom surfaces of adjacent bearings are in contiguous relation.
16 . A bearing as defined in claim 14 , wherein said bearing is formed of a rigid material.
17 . A bearing as defined in claim 16 , wherein said bearing is formed of synthetic plastic material.Join the waitlist — get patent alerts
