Abstract

Abstract A floatable device having a ridged body containing a plurality of tie points near the edge and a substantially central orifice. Several bodies may be tied in series to form a ladder for ingress and egress of boats. The body may be filled with closed cell foam to sustain buoyancy if the ridged body is pierced or cracked. The body may be tinted a bright, safety color. The ties securing the blocks together may be whipped with a clamp having a tapered end to prevent the knots from slipping.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 269 words
An improved floatable ladder arrangement for mounting on a boat, and comprising, in combination: a unitarily fabricated, rigid, body having a front surface, a back surface substantially coextensive with said front surface, and a peripheral edge defining the boundaries of said front and back surface; said front and back surface defining a preselected geometric surface, having a center line, and free of sharp edge portions; said peripheral edge having a preselected width and defining a smooth transition with said front and back surface thereby enclosing a hollow space; a plurality of first walls mounted between said front and back surface at preselected locations near the upper and lower, right and left edges of said geometric surface defining a plurality of tie point orifices remote from said center line of said body; said first walls having substantially the same width as said peripheral edge and defining a smooth transition with said front and back surface; a second wall mounted between said front and back surface substantially in the center portion of said geometric surface defining a step orifice of a preselected size; said second wall having substantially the same width as said peripheral edge and defining a smooth transition with said front and back surface; and, a plurality of ties mounted through said tie points of adjacent bodies to form a plurality of connected bodies in a predetermined, latterly stable, configuration whereby a user may tie one end of said configuration to the boat and hang the other end of said configuration over the side of the boat thereby providing a pathway for ingress/egress from the boat to the water.
Claim 2
Dependent Claim 269 words
An improved floatable ladder arrangement for mounting on a boat, and comprising, in combination: a unitarily fabricated, rigid, body having a front surface, a back surface substantially coextensive with said front surface, and a peripheral edge defining the boundaries of said front and back surface; said front and back surface defining a preselected geometric surface, having a center line, and free of sharp edge portions; said peripheral edge having a preselected width and defining a smooth transition with said front and back surface thereby enclosing a hollow space; a plurality of first walls mounted between said front and back surface at preselected locations near the upper and lower, right and left edges of said geometric surface defining a plurality of tie point orifices remote from said center line of said body; said first walls having substantially the same width as said peripheral edge and defining a smooth transition with said front and back surface; a second wall mounted between said front and back surface substantially in the center portion of said geometric surface defining a step orifice of a preselected size; said second wall having substantially the same width as said peripheral edge and defining a smooth transition with said front and back surface; and, a plurality of ties mounted through said tie points of adjacent bodies to form a plurality of connected bodies in a predetermined, latterly stable, configuration whereby a user may tie one end of said configuration to the boat and hang the other end of said configuration over the side of the boat thereby providing a pathway for ingress/egress from the boat to the water.
Claim 3
Dependent Claim 15 words
An improved floatable ladder arrangement defined in claim 1 wherein said body is air tight.
Claim 4
Dependent Claim 31 words
An improved floatable ladder arrangement defined in claim 1 further comprising: closed cell foam mounted within said body to fill the hollow space between said front side and said back side.
Claim 5
Dependent Claim 16 words
An improved floatable ladder arrangement defined in claim 1 wherein said geometric surface is a square.
Claim 6
Dependent Claim 16 words
An improved floatable ladder arrangement defined in claim 1 wherein said geometric surface is a rectangle.
Claim 7
Dependent Claim 26 words
An improved floatable ladder arrangement defined in claim 1 further comprising: a preselected color tint added to the material used to unitarily fabricate said rigid body.
Claim 8
Dependent Claim 288 words
An improved floatable ladder arrangement for mounting on a boat, and comprising, in combination: a unitarily fabricated, rigid, body having a front surface, a back surface substantially coextensive with said front surface, and a peripheral edge defining the boundaries of said front and back surface; said front and back surface defining a preselected geometric surface, having a center line, and free of sharp edge portions; said peripheral edge having a preselected width and defining a smooth transition with said front and back surface thereby enclosing a hollow space; a plurality of first walls mounted between said front and back surface at preselected locations near the upper and lower, right and left edges of said geometric surface defining a plurality of tie point orifices remote from said center line of said body; said first walls having substantially the same width as said peripheral edge and defining a smooth transition with said front and back surface; a second wall mounted between said front and back surface substantially in the center portion of said geometric surface defining a step orifice of a preselected size; said second wall having substantially the same width as said peripheral edge and defining a smooth transition with said front and back surface; a plurality of ties mounted through said tie points of adjacent bodies to form a plurality of connected bodies in a predetermined, latterly stable, configuration whereby a user may tie one end of said configuration to the boat and hang the other end of said configuration over the side of the boat thereby providing a pathway for ingress/egress from the boat to the water; and, a molded clamp mounted on each end of each of said plurality of ties to whip each bitter end.
Claim 9
Dependent Claim 288 words
An improved floatable ladder arrangement for mounting on a boat, and comprising, in combination: a unitarily fabricated, rigid, body having a front surface, a back surface substantially coextensive with said front surface, and a peripheral edge defining the boundaries of said front and back surface; said front and back surface defining a preselected geometric surface, having a center line, and free of sharp edge portions; said peripheral edge having a preselected width and defining a smooth transition with said front and back surface thereby enclosing a hollow space; a plurality of first walls mounted between said front and back surface at preselected locations near the upper and lower, right and left edges of said geometric surface defining a plurality of tie point orifices remote from said center line of said body; said first walls having substantially the same width as said peripheral edge and defining a smooth transition with said front and back surface; a second wall mounted between said front and back surface substantially in the center portion of said geometric surface defining a step orifice of a preselected size; said second wall having substantially the same width as said peripheral edge and defining a smooth transition with said front and back surface; a plurality of ties mounted through said tie points of adjacent bodies to form a plurality of connected bodies in a predetermined, latterly stable, configuration whereby a user may tie one end of said configuration to the boat and hang the other end of said configuration over the side of the boat thereby providing a pathway for ingress/egress from the boat to the water; and, a molded clamp mounted on each end of each of said plurality of ties to whip each bitter end.
