Abstract
Abstract This invention is an erosion control device in the form of a plurality of nestled, triangular-in-cross-section modules forming units. These units can be interconnected to form erosion control device of any desired length. These erosion control and refurbishing devices are preferably made from recycled plastic and can be sand colored to blend with the natural scenery. They also will not harm the environment nor injure people who come into contact with the same.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
96 words
A shoreline erosion control and refurbishing means comprising: a first elongated, generally equilateral triangle-in-cross-section module; a second elongated, generally equilateral triangle-in-cross-section module disposed upside down inside and said first module; at least one shaft means passing generally vertically through said modules to lock the same, one relative to the other to form a unit means; and an end plate means mounted over open ends of said first module whereby the forces of nature coming into contact with the erosion control and refurbishing means will shown normal erosion and cause an area adjacent thereto to become refurbished.
Claim 2
Dependent Claim
96 words
A shoreline erosion control and refurbishing means comprising: a first elongated, generally equilateral triangle-in-cross-section module; a second elongated, generally equilateral triangle-in-cross-section module disposed upside down inside and said first module; at least one shaft means passing generally vertically through said modules to lock the same, one relative to the other to form a unit means; and an end plate means mounted over open ends of said first module whereby the forces of nature coming into contact with the erosion control and refurbishing means will shown normal erosion and cause an area adjacent thereto to become refurbished.
Claim 3
Dependent Claim
27 words
The means of claim 1 whereby a plurality of units can be secured together, end to end, with end plate means mounted on the open ends thereof.
Claim 4
Dependent Claim
20 words
The means of claim 1 wherein the modules forming each unit means are constructed at least partially from recycled plastic.
Claim 5
Dependent Claim
42 words
The means of claim 1 wherein an upper end of said shaft means terminates in a handle and a lower end of said shaft means terminates in an auger configuration whereby said unit means can be readily secured in its use location.
Claim 6
Dependent Claim
19 words
The means of claim 1 including a fin means downwardly protecting from a lower surface of said unit means.
Claim 7
Dependent Claim
15 words
The means of claim 5 wherein reinforcing gussets are provided for strengthening said fin means.
Claim 8
Dependent Claim
35 words
The means of claim 1 wherein at least one opening is provided through said end plate means whereby water salt, sand and other water-borne materials can ingress therethrough to an interior of said unit means.
Claim 9
Dependent Claim
19 words
The means of claim 7 wherein at least four openings are provided through each of said end plate means.
Claim 10
Dependent Claim
25 words
The means of claim 7 wherein valve means is provided to allow . ingress but to prevent egress of silt, sand and other water-borne materials.
Claim 11
Dependent Claim
22 words
The means of claim 9 wherein said valve means is a flap valve mounted on the interior of said end plate means.
Claim 12
Dependent Claim
42 words
The means of claim 9 wherein a means is provided for releasably locking said valve means closed whereby said unit can be floated to its use location and the valve means released to allow ingress of silt, sand and other water-borne materials.
Claim 13
Dependent Claim
28 words
The means of claim 11 wherein said locking means is a pin engaging an eyelet secured to a flap valve with said eyelet outwardly projecting through said opening.
Claim 14
Independent Claim
69 words
The method of deploying a shoreline erosion control and refurbishing means comprising: forming at least one elongated, generally equilateral triangle-in-cross-section unit; passing a shaft through said unit with a handle mounted on one end and a helical plate mounted on the opposite end; moving said unit to its use location; and manipulating said handle to cause said helical plate to auger into the ground to secure said unit thereto.
Claim 15
Independent Claim
69 words
The method of deploying a shoreline erosion control and refurbishing means comprising: forming at least one elongated, generally equilateral triangle-in-cross-section unit; passing a shaft through said unit with a handle mounted on one end and a helical plate mounted on the opposite end; moving said unit to its use location; and manipulating said handle to cause said helical plate to auger into the ground to secure said unit thereto.
Claim 16
Dependent Claim
37 words
The method of claim 13 wherein said unit is floated to its use location and valve means are opened to allow the same to fill with water and sink to the bottom prior to the manipulated step.
Claim 17
Dependent Claim
26 words
The method of claim 14 wherein said valve means are flap valves which allow ingress of silt, sand and other water-borne materials prevent the egress thereof.
Claim 18
Dependent Claim
60 words
The method of claim 13 wherein a first elongated, generally equilateral triangle-in-cross-section module is formed; a second elongated, generally equilateral triangle-in-cross-section module is formed; said second modules is disposed upside down inside said first module; and said shaft is passed vertically through said first and second module to lock the same, one relative to the other, to form said unit.
Claim 19
Dependent Claim
16 words
The method of claim 13 wherein said unit is formed at least partially from recycled plastic.
