Abstract
Abstract A ship safety device comprising normally-folded inflatable gas bags secured to broadsides of a ship, which gas bags are connected to a pressure-gas source through a valve for selective inflation in emergency. Each gas bag has a flange, which is secured to the ship broadside by fixtures, and two folding portions extending in the longitudinal direction of the ship for facilitating the folding thereof in an easily inflatable and deflatable fashion.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
120 words
A ship safety device, comprising at least one normally-folded inflatable gas bag secured to broadside of a ship, a pressure-gas source installed on board the ship, and a valved conduit communicating the pressure-gas source to the bag for selective inflation of the bag in case of emergency, said gas bag having a flat mounting portion to be kept in contact with the broadside of the ship and a flange formed along the periphery of the mounting portion, said flange having at least one reinforcing member embedded therein and being fastened to the broadside of the ship by fixtures, said fixtures forming long fixture contact surfaces extending along the flange so as to urge the flange continuously toward the ship broadside.
Claim 2
Dependent Claim
120 words
A ship safety device, comprising at least one normally-folded inflatable gas bag secured to broadside of a ship, a pressure-gas source installed on board the ship, and a valved conduit communicating the pressure-gas source to the bag for selective inflation of the bag in case of emergency, said gas bag having a flat mounting portion to be kept in contact with the broadside of the ship and a flange formed along the periphery of the mounting portion, said flange having at least one reinforcing member embedded therein and being fastened to the broadside of the ship by fixtures, said fixtures forming long fixture contact surfaces extending along the flange so as to urge the flange continuously toward the ship broadside.
Claim 3
Dependent Claim
55 words
A ship safety device according to claim 1 and further comprising hooks secured to broadside of the ship, eye pieces secured to the gas bag, and a rope extending between the hooks and the eye pieces in zigzag fashion when the gas bag is deflated and folded so as to hold the gas bag folded.
Claim 4
Dependent Claim
75 words
A ship safety device according to claim 1 and further comprising a cover member having lower edge integrally secured to lower edge of said flAnge, hooks secured to broadside of the ship, eye pieces secured to said cover member, and a rope extending between the hooks and the eye pieces in zigzag fashion when the gas bag is deflated and folded so as to hold the gas bag folded by covering the folded gas bag.
Claim 5
Dependent Claim
107 words
A ship safety device according to claim 1, wherein said gas bag is formed by an elastomer bag wall and has two permanent folding veins extending in the bag wall in a direction parallel to the cruising direction of the ship, said two veins defining three gas bag wall sections including one wall section between the two veins, one wall section above, and another wall section below the inter-vein wall section, said three wall sections forming a unitary gas bag upon inflation, while said three wall sections being automatically folded one on the other along the ship broadside upon removal of internal pressure from the gas bag.
Claim 6
Dependent Claim
97 words
A ship safety device according to claim 1, wherein said gas bag has two folding portions extending in parallel to the cruising direction of the ship, and the gas bag is foldable upon deflation in such a manner that upper portion of the gas bag which extends upwardly from the upper one of said folding portions is held adjacent the flat mounting portion, while covering the entire folded gas bag with lower portion of the gas bag, said lower portion extending between the lower one of said folding portions and lower edge of said flat mounting portion.
Claim 7
Dependent Claim
96 words
A ship safety device according to claim 5 and further comprising a plurality of ropes, each having one end connected to said gas bag, a winch mounted on board the ship and having opposite ends of the ropes connected thereto, and a rope guide means mounted on board the ship between the gas bag and the winch so as to guide movement of intermediate portions of said ropes, said winch selectively taking up said ropes for folding the gas bag along said folding portions and selectively releasing said ropes for allowing said gas bag to inflate.
Claim 8
Dependent Claim
35 words
A ship safety device according to claim 6, wherein said valved conduit includes a three-way valve selectively communicating said gas bag either to said pressure-gas source for inflation thereof, or to atmosphere for deflation thereof.
Claim 9
Dependent Claim
28 words
A ship safety device according to claim 7 and further comprising a holding lug integrally secured to said gas bag, said ropes being connected to said holding lug.
Claim 10
Dependent Claim
27 words
A ship safety device according to claim 5, wherein said folding portions of said gas bag have thinner walls than the remaining portions of the gas bag.
