Abstract
Abstract The hull of a ship is maintained at a distance from a quay or the hull of another ship by means of a fender having a deformable chamber whose wall is composed of flexible toric elements. The edges of the latter are tightened between ported flanges having the general shape of the rim of a car wheel and bearing stops for limiting the crushing of the chamber. Alternatively, the crushing limiter stop is a cylindrical sleeve of compressible resilient material fitted to a bottom of the chamber and projecting therein towards the opposite bottom, so as to constitute by itself a permanent backing auxiliary fender.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
112 words
In a fender device having a backing plate and a flexible wall fitted at one end thereof to said backing plate and projecting therefrom to another end to bound a deformable hollow chamber bottomed by said backing plate and collapsible by crushing of said wall towards said backing plate, the improvement comprising a resilient deformable generally cylindrical sleeve housed within said hollow chamber in spaced relationship with said wall thereof with a peripheral clearance being left between said sleeve and said wall for the entire length and periphery of said wall, said sleeve being fitted to said backing plate and projecting therefrom to end short of said another end of said wall.
Claim 2
Dependent Claim
112 words
In a fender device having a backing plate and a flexible wall fitted at one end thereof to said backing plate and projecting therefrom to another end to bound a deformable hollow chamber bottomed by said backing plate and collapsible by crushing of said wall towards said backing plate, the improvement comprising a resilient deformable generally cylindrical sleeve housed within said hollow chamber in spaced relationship with said wall thereof with a peripheral clearance being left between said sleeve and said wall for the entire length and periphery of said wall, said sleeve being fitted to said backing plate and projecting therefrom to end short of said another end of said wall.
Claim 3
Dependent Claim
43 words
Device as claimed in claim 1, wherein said generally cylindrical sleeve has an outer diameter about twice its inner diameter and a length substantially equal to two-thirds of said outer diameter and to half the inter-bottom span of said deformable chamber when extended.
Claim 4
Dependent Claim
43 words
Device as claimed in claim 1, further comprising a ring fitted outwardly of said chamber on the outer face of said opposite bottom thereof and in alinement and cooperative relation with said generally cylindrical sleeve for engagement therewith upon crushing of said chamber.
Claim 5
Dependent Claim
56 words
Device as claimed in claim 3, further comprising a ported plate at said opposite bottom of said deformable chamber to communicate the inside thereof with said bottom outer face, and a peripheral lip fitted to said plate and protruding outwardly of said chamber beyond said ring, whereby said ring is sunk with respect to said lip.
Claim 6
Dependent Claim
19 words
Device as claimed in claim 4, wherein said plate comprises separate ports opening respectively inside and outside said ring.
Claim 7
Dependent Claim
15 words
Device as claimed in claim 4, wherein said ring has flow passage means formed therethrough.
Claim 8
Dependent Claim
19 words
Device as claimed in claim 1, wherein a peripheral groove is formed on said sleeve to facilitate deformation thereof.
Claim 9
Dependent Claim
28 words
Device as claimed in claim 1, wherein said generally cylindrical sleeve is fitted in said chamber so that the respective axes thereof are substantially parallel to each other.
Claim 10
Dependent Claim
28 words
Device as claimed in claim 1, wherein said generally cylindrical sleeve is fitted in said chambeR so that the respective axes thereof are substantially transverse to each other.
