Abstract

Abstract A bumper assembly for a marine structure where a vertical resiliently encased main cylinder is secured at the upper end to the marine structure by a releasable connection with the lower support for the main cylinder including an upstanding stab post extending into the bottom of the main cylinder and coaxially aligned with the upper end of the main cylinder. A resilient cylinder is positioned between the inside of the main cylinder and the outside of the stab post. Preferably the internal diameter of the resilient cylinder is slightly larger than the diameter of the stab post and provides a pivotal cushion at the bottom of the main cylinder to permit angular displacement of the main cylinder from the vertical position.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 67 words
In a bumper assembly where a vertical main cylinder is secured at the upper end to a marine structure by a releasable connection, the combination comprising: a. a lower support for said main cylinder including an upstanding stab post extending into the bottom of said main cylinder in coaxial alignment with said upper end; and b. a resilient cylinder between said main cylinder and said stab post.
Claim 2
Dependent Claim 67 words
In a bumper assembly where a vertical main cylinder is secured at the upper end to a marine structure by a releasable connection, the combination comprising: a. a lower support for said main cylinder including an upstanding stab post extending into the bottom of said main cylinder in coaxial alignment with said upper end; and b. a resilient cylinder between said main cylinder and said stab post.
Claim 3
Dependent Claim 15 words
The combination of claim 1 wherein said stab post includes a conically shaped upper end.
Claim 4
Dependent Claim 50 words
The combination of claim 1 wherein said resilient cylinder comprises a cylindrical rubber liner secured to the bottom portion of the inside of said main cylinder, such that said liner contacts with the periphery of said stab post to provide a pivotal cushion at the bottom of said main cylinder.
Claim 5
Dependent Claim 30 words
The combination of claim 3 wherein the height of said cylindrical rubber liner is about equal to the distance said stab post extends into the bottom of said main cylinder.
Claim 6
Dependent Claim 119 words
In a bumper assembly where a vertical main cylinder is secured at the upper end to a marine structure by a releasable connection, the combination comprising: a. a lower support for said main cylinder secured to said marine structure including an upstanding stab post having a conically shaped upper end and extending into the bottom of said main cylinder, coaxially aligned with said upper end; and b. a resilient cylinder secured to the bottom portion of the inside of said main cylinder and of internal diameter slightly larger than the diameter of said stab post, such that said resilient cylinder contacts the periphery of said stab post to provide a pivotal cushion at the bottom of said main cylinder.
Claim 7
Dependent Claim 119 words
In a bumper assembly where a vertical main cylinder is secured at the upper end to a marine structure by a releasable connection, the combination comprising: a. a lower support for said main cylinder secured to said marine structure including an upstanding stab post having a conically shaped upper end and extending into the bottom of said main cylinder, coaxially aligned with said upper end; and b. a resilient cylinder secured to the bottom portion of the inside of said main cylinder and of internal diameter slightly larger than the diameter of said stab post, such that said resilient cylinder contacts the periphery of said stab post to provide a pivotal cushion at the bottom of said main cylinder.
Claim 8
Dependent Claim 83 words
In a bumper assembly for a marine structure: a. a resiliently encased vertical main cylinder; b. means for securing the upper end of said main cylinder to said marine structure; c. a lower support for said main cylinder including an upstanding stab post extending into the bottom of said main cylinder, coaxially aligned with said upper end; and d. a resilient cylinder secured to the inside of said main cylinder and of internal diameter slightly larger than the diameter of said stab post.
Claim 9
Dependent Claim 83 words
In a bumper assembly for a marine structure: a. a resiliently encased vertical main cylinder; b. means for securing the upper end of said main cylinder to said marine structure; c. a lower support for said main cylinder including an upstanding stab post extending into the bottom of said main cylinder, coaxially aligned with said upper end; and d. a resilient cylinder secured to the inside of said main cylinder and of internal diameter slightly larger than the diameter of said stab post.
Claim 10
Dependent Claim 22 words
The bumper assembly of claim 6 wherein said means for securing the upper end of said main cylinder comprises a releasable connection.
Claim 11
Dependent Claim 26 words
