DESCRIPTION OF THE PREFERRED EMBODIMENT 
With reference now to the drawings, and in particular to FIGS. 1 through 6 
thereof, a new Plastic Timber Landscaping System embodying the principles 
and concepts of the present invention and generally designated by the 
reference numeral 10 will be described. 
More specifically, it will be noted that the Plastic Timber Landscaping 
System 10 comprises at least one elongated hollow rectangular member 20, 
and at least one joiner pipe 30 removably projecting through an end of the 
elongated hollow rectangular member 20. 
As best illustrated in FIGS. 1 through 4, it can be shown that the each 
elongated hollow rectangular member 20 includes a planar wood grain top 
23. At least one arcuate wood grain side 22 is adjacent to the planar wood 
grain top 23. A first knockout passage 24 is near one end of the elongated 
hollow rectangular member 20 projecting into the planar wood grain top 23 
through the bottom surface. A second knockout passage 26 is near the first 
knockout passage 24 spaced approximately the width of the elongated hollow 
rectangular member 20, and projecting into the planar wood grain top 23 
through the bottom surface. A third knockout passage 28 is near the end 
opposite the first and second knockout passages 24 and 26 the same 
distance away from the end as the first knockout passage 24, and 
projecting into the planar wood grain top 23 into the bottom surface. A 
fourth knockout passage 29 is near the third knockout passage 28 spaced 
approximately the same distance as the second knockout passage 26 from the 
first knockout passage 24, and projecting into the planar wood grain top 
23 into the bottom surface. A plurality of the elongated hollow 
rectangular members 20 are preferably staggered orthogonally to one 
another forming a hollow square structure which retains dirt 12 as shown 
in FIG. 1 of the drawings. The elongated hollow rectangular members 20 are 
secured to one another by a plurality of joiner pipes 30 projecting 
through the corresponding knockout members of each elongated hollow 
rectangular member 20. The joiner pipes 30 include a pair of finishing 
caps 32 removably secured at each end which prevent the joiner pipes 30 
from being removed from the knockout passages and produce a finished 
appearance to the present invention as shown in FIG. 1 of the drawings. 
The finishing cap 32 is constructed so as to resemble the planar wood 
grain top 23. 
In an alternative embodiment as shown in FIG. 5 of the drawings, at least 
one hollow semi-circular member 40 is formed to the appearance of natural 
wood. The hollow semi-circular member 40 includes a first end knockout 
passage 42 near one end. A second end knockout passage 44 is positioned 
near the end opposite of the first end knockout passage 42. A first 
central knockout passage 46 is positioned near one side of the center 
point on the hollow semi-circular member 40. A second central knockout 
passage 48 is positioned near the center point on the hollow semi-circular 
member 40 opposite of the first central knockout passage 46. A joiner pipe 
30 projects through a plurality of corresponding knockout passages of the 
hollow semi-circular members 40 forming a hollow cylindrical structure. 
The joiner pipes 30 include a pair of finishing caps 32 removably secured 
at each end which prevent the joiner pipes 30 from being removed from the 
knockout passages, where the finishing caps 32 have a wood grain 
appearance providing a finished appearance to the present invention. 
In another alternative embodiment of the present invention as shown in FIG. 
6 of the drawings, at least one semi-circular member 52 has one end 
projecting a finite distance along the tangential path including a 
plurality of aligning knockout passages 56 near the ends. At least one 
straight member 54 includes a plurality of aligning knockout passages 56 
which correspond to the aligning knockout passages 56 of the semi-circular 
member 52. A joiner pipe 30 projects through the corresponding aligning 
knockout passages 56 forming a hollow oblong structure 50 which retains 
dirt 12. The joiner pipes 30 include a pair of finishing caps 32 removably 
secured at each end which prevent the joiner pipes 30 from being removed 
from the aligning knockout passages, where the finishing caps 32 have a 
wood grain appearance providing a finished appearance to the present 
invention. 
In use, the user positions four elongated hollow rectangular members 20 end 
to end into a shape of a square as best shown by the bottom layer of FIG. 
1 of the drawings. The user then positions another four elongated hollow 
rectangular members 20 on top of the previous layer, where each elongated 
hollow rectangular member 20 of the top layer overlap and are orthogonal 
to the end of one elongated hollow rectangular member 20 of the bottom 
layer, and so forth. The user then projects a joiner pipe 30 though each 
corresponding knockout passage of the elongated hollow rectangular members 
20, thereby securing the bottom and top layers forming a strengthened and 
stable structure which retains dirt 12. 
As to a further discussion of the manner of usage and operation of the 
present invention, the same should be apparent from the above description. 
Accordingly, no further discussion relating to the manner of usage and 
operation will be provided. 
With respect to the above description then, it is to be realized that the 
optimum dimensional relationships for the parts of the invention, to 
include variations in size, materials, shape, form, function and manner of 
operation, assembly and use, are deemed readily apparent and obvious to 
one skilled in the art, and all equivalent relationships to those 
illustrated in the drawings and described in the specification are 
intended to be encompassed by the present invention. 
Therefore, the foregoing is considered as illustrative only of the 
principles of the invention. Further, since numerous modifications and 
changes will readily occur to those skilled in the art, it is not desired 
to limit the invention to the exact construction and operation shown and 
described, and accordingly, all suitable modifications and equivalents may 
be resorted to, falling within the scope of the invention.
