Description
Background of the Invention
The invention relates to an instant levy block system. More particularly, the invention relates to a system of modular, reusable blocks, for creating a levy.
Severe flood conditions have occurred throughout the country in the recent era. Although flooding is expected by those living on coastal shorelines, flooding can also occur in unexpected locations. Flood damage can be as devastating as any other natural or man-made disaster.
Other attempts at preventing flood damage by creating a dam or levy involve apparatus that is complicated in manufacture and on-site assembly, is heavy and cumbersome, and does not provide adequate protection.
U.S. Pat. No. 4,330,224 to Muramatsu et al., discloses a collapsible rubber dam installations which is filled with a fluid upon on-site installation.
U.S. Pat. No. 4,692,060 to Jackson, discloses a water-bag dam or dike and method. A water-bag is filled with water, and assumes the shape of a triangular prism.
U.S. Pat. No. 4,981,392 to Taylor, discloses a water inflatable structural module that comprises two cylindrical water holding chambers joined along a horizontal mid-plane.
U.S. Pat. No. 5,040,919 to Hendrix, discloses a device for controlling flood waters and/or hazardous liquid spills.
While these units may be suitable for the particular purpose employed, or to general use, they would not be as suitable for the purposes of the present invention as hereafter described.
Summary of the Invention
It is an object of the invention to produce a levy block system that can effectively protect property from rising flood waters.
It is another object of the invention to produce a levy block system that can be quickly and easily deployed into use, and then disassembled for reuse.
It is a further object of the invention to produce a levy block system that is inexpensive to manufacture.
It is a still further object of the invention to produce a levy block system that provides a large degree of structural strength and stability per unit.
The invention is an instant block levy system, for constructing a levy, comprising a plurality of blocks, a plurality of connecting pegs, and a plurality of stakes. The block has a top surface and bottom surface, upper shaftways extending vertically into the top surface, and lower shaftways extending vertically into the bottom surface. The block has a ballasting chamber, and a fill hole in fluid communication with the ballasting chamber. The blocks are stacked, such that a lower shaftway from a top block is concentric with a upper shaftway from a bottom block, so that the upper and lower shaftways can be connected with the connecting peg. The block has stake shaftways, extending through the block from the top surface to the bottom surface, so that the stake may be inserted therethrough, to anchor the block to the ground.
To the accomplishment of the above and related objects, the invention may be embodied in the form illustrated in the accompanying drawings. Attention is called to the fact that variations are contemplated as being part of the present invention, limited only by the scope of the claims.

Detailed Description of the Preferred Embodiment
FIG. 1 illustrates a block 20, which is the basic unit of the levy system of the present invention, by which a plurality of blocks 20 are combined to form a levy. The block 20 is in the form of a rectangular prism, and has a top surface 22, a bottom surface 24, and four sides 25.
The top surface 22 has a fill hole 26, for receiving a fill plug 28, having a threaded fill shaft 30. The fill hole 26 has a file hole counterbore 29, so that the fill plug 28, when fully inserted into the fill hole 26, can rest below the top surface 22. Upper shaftways 32 extend vertically into the block 20 from the top surface 22. The upper shaftways 32 have substantially the same diameter, and extend substantially the same distance into the block 20.
Stake shaftways 34 extend vertically through the block 20 from the top surface 22 to the bottom surface 24. A stake 36, approximately the same diameter as the stake shaftway 34 can be used to anchor the block to the ground. The stake 36 may have an enlarged optional stake head 38. The stake 36 is further illustrated in FIG. 6. The stake has a sharp end 39, opposite the stake head 38.
A drain hole 40 is present in the block near the bottom surface 24, on one of the sides 25. The drain hole 40 receives a drain hole plug 42, having a threaded drain shaft 44. The threaded drain shaft 44 creates a tight seal, even under undue pressure against the drain hole plug 42.
A pair of end plates 46 are mounted onto two opposite sides 25. The opposite sides are connected by a connecting edge 48. The end plates are each substantially the same size as the side 25 to which they are mounted, are mounted parallel to each other, and are each offset an equal distance from the connecting edge 48.
FIG. 2 is a top plan view, illustrating the block 20. Ballasting chambers 50, illustrated with hidden lines, are in fluid communication with the fill hole 26, and the drain hole 40. The ballasting chambers 50 are used for holding water within the block 20, to increase its weight, and thus, the overall stability of the levy constructed with the blocks.
Lower shaftways 52 extend vertically into the block from the bottom surface. The lower shaftways 52 do not extend fully through the block 20, and thus appear as hidden lines in FIG. 2. The lower shaftways 52, each extend substantially the same distance up into the block 20. The lower shaftways 52 are of a diameter that is substantially the same as the diameter of the upper shaftways 32.
Each stake shaftway 34 has a stake shaftway counterbore 35, for accepting the stake head 38. The stake shaftway counterbore 35 allows the stake head 38 to rest below the top surface 22.
Referring to FIG. 10, the relative positioning of the upper shaftways 32 and lower shaftways 52 is such that two blocks can be stacked on top of each other, with a top block 20T staggered halfway across a bottom block 20B. When the blocks are thus arranged, at least one upper shaftway on the bottom block will be concentric with a lower shaftway of the top block. The blocks can then be connected with a connecting peg 54.
Referring to FIG. 7, the connecting peg 54 is substantially cylindrical. The diameter of the connecting peg 54 is substantially the same as the diameter of the upper shaftway 32 and lower shaftway 52.
Referring to FIG. 10, the length of the connecting peg 54 is substantially the same as the sum of the distance that the upper shaftway 32 extends into the bottom block 20B and the distance that the lower shaftway 52 extends into the top block 20T.
FIG. 3 and FIG. 4 illustrate the relative positioning of the end plates 46. Referring to FIG. 3, the end plates are attached to a pair of opposite sides 25, at a fixed distance from the connecting edge 48. Also illustrated is that the end plates 46 are essentially parallel to each other.
FIG. 4 details an optional drain plug cut-out 56, in the end plate 46 of the side 25 bearing the drain plug 42.
FIG. 5 illustrates the block 20, with an end plate removed, according to line 5--5 in FIG. 2. The ballasting chamber 50 is shown with hidden lines, as is the fill hole 26. The drain hole 40, the ballasting chamber 50, and the fill hole 26 are all in fluid communication.
FIG. 8 and 9 illustrate that when the blocks 20 are stacked, adjacent end plates 46 come into close proximity, creating a seal therebetween.
The blocks 20 may be formed of plastic, or firm rubber. The end plates 46 should preferably be made of rubber, to create a tight seal between the end plates of adjacent blocks. The connecting pegs may be fabricated out of plastic, rubber or steel. The stakes should be made of steel.
