Abstract
Abstract A shock absorbing arrangement for marine structures includes an annular elongated hollow body with an elastomer body molded adjacent one end of the annular body, the elastomer body having a plurality of circumferentially spaced voids therein extending from one end of the body and terminating in spaced relation relative to the other end of the body. A cylinder is molded in the center of the body and has an open end facing in the same direction as the open end of the voids and a closed end adjacent but spaced from the other end of the elastomer body and the elastomer body is provided with an enlargement adjacent the closed cylinder end to serve as a shock absorber and bumper.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
165 words
A shock absorbing arrangement for marine structures comprising: a. an annular, elongated hollow body; b. an elastomer body molded in said hollow body adjacent one end thereof; c. a cylinder molded centrally of and extending longitudinally of said elastomer body; d. said cylinder having one end projecting beyond one end of said elastomer body and having a closed end positioned in spaced relation to and adjacent the other end of said elastomer body; e. said elastomer body having a plurality of voids circumferentially spaced about said cylinder, said voids each having an open end facing toward the cylinder end which projects beyond said one elastomer end and terminating in spaced relation to the other end of said elastomer body to form a closed end on said void; and f. said voids having a configuration so that the circumference of said elastomer body between adjacent voids and adjacent said cylinder approximates the circumference of said elastomer body between adjacent voids and adjacent said annular, hollow body.
Claim 2
Dependent Claim
165 words
A shock absorbing arrangement for marine structures comprising: a. an annular, elongated hollow body; b. an elastomer body molded in said hollow body adjacent one end thereof; c. a cylinder molded centrally of and extending longitudinally of said elastomer body; d. said cylinder having one end projecting beyond one end of said elastomer body and having a closed end positioned in spaced relation to and adjacent the other end of said elastomer body; e. said elastomer body having a plurality of voids circumferentially spaced about said cylinder, said voids each having an open end facing toward the cylinder end which projects beyond said one elastomer end and terminating in spaced relation to the other end of said elastomer body to form a closed end on said void; and f. said voids having a configuration so that the circumference of said elastomer body between adjacent voids and adjacent said cylinder approximates the circumference of said elastomer body between adjacent voids and adjacent said annular, hollow body.
Claim 3
Dependent Claim
20 words
The invention of claim 1 wherein said elastomer body is provided with an enlargement centrally disposed on said other end.
Claim 4
Dependent Claim
35 words
The invention of claim 1 wherein said circumferential spaced voids are generally triangular in configuration with the apex of the triangle adjacent said cylinder and the base of said triangle adjacent said annular, hollow body.
Claim 5
Dependent Claim
13 words
The invention of claim 2 wherein said enlargement is generally hemispherical in configuration.
