Abstract
Abstract The improved revetment system is created using a plurality of substantially identical blocks which comprise a body having at least one channel therein leading to a slot and at least one arm extending outwardly of the body and terminating in a locking ear. The ear engages in a slot of an adjacent block and is of less depth than the slot, with the arm being of a length at least equal to and preferably greater than that of the channel, the slot including a removable spacer tab therein which abuts a terminal edge of the ear to keep the blocks spaced apart and an area of the block defined by the arm and ear having an arcuately downwardly sloped top surface with a terminal edge of the ear defining a lowermost position along the arcuate surface.

Claim 5
Dependent Claim
85 words
A block for use in creating a revetment system, the block having a body including at least one lateral channel terminating in an interior slot and at least one ear engaged by an arm extending laterally outwardly of the body, a top surface area of the block defined by the arm and the at least one ear sloping arcuately downwardly from a top surface of the body in a manner such that a terminal edge of the ear defines a lowermost point along the arc.
Claim 6
Dependent Claim
15 words
The block of claim 3 wherein a removable spacer tab is incorporated into said slot.
Claim 7
Dependent Claim
134 words
A block for use in creating a revetment system, the block having a body including at least one lateral channel terminating in an interior slot and at least one ear engaged by an arm extending laterally outwardly of the body, the arm being of a length at least equal to a length of the at least one channel and the at least one ear having a width and depth less than a width and depth of the slot, the slot incorporating a removable spacer tab and a top surface area of the block defined by the arm and the at least one ear sloping arcuately downwardly from a top surface of the body in a manner such that a terminal edge of the at least one ear defines a lowermost point along the arc.
Claim 8
Dependent Claim
134 words
A block for use in creating a revetment system, the block having a body including at least one lateral channel terminating in an interior slot and at least one ear engaged by an arm extending laterally outwardly of the body, the arm being of a length at least equal to a length of the at least one channel and the at least one ear having a width and depth less than a width and depth of the slot, the slot incorporating a removable spacer tab and a top surface area of the block defined by the arm and the at least one ear sloping arcuately downwardly from a top surface of the body in a manner such that a terminal edge of the at least one ear defines a lowermost point along the arc.
Claim 9
Dependent Claim
14 words
The block of claim 5 wherein said interior slot has an inner lateral wall.
Claim 10
Dependent Claim
18 words
The block of claim 6 wherein said spacer tab extends into said slot from said inner lateral wall.
Claim 11
Dependent Claim
20 words
The block of claim 7 wherein said spacer tab is engaged to said inner lateral wall by a narrow neck.
Claim 12
Dependent Claim
26 words
The block of claim 8 wherein said spacer tab abuts the terminal edge of an ear of an adjacent block which is engaged within said slot.
Claim 13
Dependent Claim
26 words
The block of claim 9 wherein said ear of said adjacent block slides toward and away from said lateral wall when said spacer tab is removed.
Claim 14
Dependent Claim
26 words
The block of claim 10 wherein an arm of said adjacent block is slidably engaged within said at least one lateral channel leading to said slot.
Claim 15
Dependent Claim
25 words
The block of claim 11 wherein a plurality of adjacent blocks engage each other in the form of a matrix to produce a revetment system.
Claim 16
Dependent Claim
10 words
The block of claim 12 having a plurality of arms.
Claim 17
Dependent Claim
11 words
The block of claim 12 having a plurality of interior slots.

Dependent Claim
14 words
The block of claim 12 having an equal plurality of arms and interior slots.
Claim 19
Dependent Claim
104 words
A revetment system comprising a plurality of interlocking blocks, each block having a body including at least one lateral channel terminating in an interior slot and at least one ear engaged by an arm extending laterally outwardly of the body, the arm being of a length at least equal to a length of the at least one channel and the ear having a width and depth less than a width and depth of the slot, the slot incorporating a removable spacer tab therein against which a terminal edge of the ear of an adjacent block abuts to maintain a spaced relationship between the blocks.
Claim 20

Claim 24
Dependent Claim
132 words
A revetment system comprising a plurality of interlocking blocks, each block having a body including at least one lateral channel terminating in an interior slot incorporating a removable spacer tab and at least one ear engaged by an arm extending laterally outwardly of the body, the arm being of a length at least equal to a length of the at least one channel and the at least one ear having a width and depth less than a width an depth of the slot, and a top surface area of the block defined by the arm and the at least one ear sloping arcuately downwardly from a top surface of the body in a manner such that a terminal edge of the at least one ear defines a lowermost point along the arc.
