Abstract
Abstract A plant-growth structure equipped with a growth media in which seeds can be planted and nurtured thereby into mature plant growth suitable for harvesting, in the case of agricultural plants. The structure includes an elongated container providing a chamber therealong in which such growth media resides, and the container has sidewalls provided at their upper ends with outwardly extending flanges to which a top cover overlying such chamber and the growth media therein is releasably attached by means of clamp-type fasteners. An irrigation system runs through the chamber to enable the growth media and plant life therein to be irrigated, and a drainage system associated with the container permits any excess liquids resulting from irrigation to drain from the growth media and chamber.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
198 words
A plant-growth structure comprising a longitudinally extending rigid container having a bottom wall and side walls extending upwardly therefrom and end walls cooperative with said bottom and side walls to provide a chamber for receipt therein of a growth medium for plant life, an irrigation conduit for supplying such growth medium with liquids, a drainage system including an outlet provided by said container to enable excess liquids to drain from such growth medium, said sidewalls having outwardly projecting flanges adjacent their upper edges, a top closure extendable over said chamber in overlying relation with said flanges, fastener means for releasably securing said top closure to said flanges, said bottom wall extending upwardly and inwardly from said sidewalls to a higher elevation adjacent its longitudinal center and along the longitudinal edges thereof and provided along such center with a longitudinally extending recess receiving said irrigation conduit, said conduit being provided with longitudinally spaced apertures therealong through which said irrigation liquids can be released into such growth medium, and said bottom wall having a pair of longitudinally extending channels respectively disposed along the longitudinal edges thereof at a lower elevation than said recess for carrying excess liquids to said outlet.
Claim 2
Dependent Claim
198 words
A plant-growth structure comprising a longitudinally extending rigid container having a bottom wall and side walls extending upwardly therefrom and end walls cooperative with said bottom and side walls to provide a chamber for receipt therein of a growth medium for plant life, an irrigation conduit for supplying such growth medium with liquids, a drainage system including an outlet provided by said container to enable excess liquids to drain from such growth medium, said sidewalls having outwardly projecting flanges adjacent their upper edges, a top closure extendable over said chamber in overlying relation with said flanges, fastener means for releasably securing said top closure to said flanges, said bottom wall extending upwardly and inwardly from said sidewalls to a higher elevation adjacent its longitudinal center and along the longitudinal edges thereof and provided along such center with a longitudinally extending recess receiving said irrigation conduit, said conduit being provided with longitudinally spaced apertures therealong through which said irrigation liquids can be released into such growth medium, and said bottom wall having a pair of longitudinally extending channels respectively disposed along the longitudinal edges thereof at a lower elevation than said recess for carrying excess liquids to said outlet.
Claim 3
Dependent Claim
67 words
The structure of claim 1 in which said fastener structure includes a pair of clamps respectively cooperative with said flanges for securing said top closure thereto, in which said top closure is a relatively thin flexible membrane, and in which each of said clamps is a substantial continuous C-shaped member of substantially the same length as said flanges so as to extend from end to end thereof.
Claim 4
Dependent Claim
27 words
The structure of claim 1 in which said container is relatively rigid, and in which said end walls are removably securable to the side and bottom walls.
Claim 5
Dependent Claim
196 words
A plant-growth structure comprising a longitudinally extending rigid container having a bottom wall and sidewalls extending upwardly therefrom and end walls cooperative with said bottom and sidewalls to provide a chamber for receipt therein of a growth medium for plant life, an irrigation conduit for supplying such growth medium with liquids, a drainage system including an outlet provided by said container to enable excess liquids to drain from such growth medium, said bottom wall extending upwardly and inwardly to a higher elevation adjacent its longitudinal center than along the longitudinal edges thereof and being Provided along such center with a longitudinally extending recess receiving said irrigation conduit, said conduit having longitudinally spaced apertures through which irrigation liquids can be released into such growth medium, and at least one of said end walls being provided with a pair of transversely spaced outlet ports defining the aforesaid outlet and with an opening passing said irrigation conduit therethrough, said bottom wall having a pair of longitudinally extending channels respectively communicating with said outlet ports and disposed along the longitudinal edges of said bottom wall at a lower elevation than said recess for carrying excess liquids to said outlet ports.
Claim 6
Dependent Claim
196 words
A plant-growth structure comprising a longitudinally extending rigid container having a bottom wall and sidewalls extending upwardly therefrom and end walls cooperative with said bottom and sidewalls to provide a chamber for receipt therein of a growth medium for plant life, an irrigation conduit for supplying such growth medium with liquids, a drainage system including an outlet provided by said container to enable excess liquids to drain from such growth medium, said bottom wall extending upwardly and inwardly to a higher elevation adjacent its longitudinal center than along the longitudinal edges thereof and being Provided along such center with a longitudinally extending recess receiving said irrigation conduit, said conduit having longitudinally spaced apertures through which irrigation liquids can be released into such growth medium, and at least one of said end walls being provided with a pair of transversely spaced outlet ports defining the aforesaid outlet and with an opening passing said irrigation conduit therethrough, said bottom wall having a pair of longitudinally extending channels respectively communicating with said outlet ports and disposed along the longitudinal edges of said bottom wall at a lower elevation than said recess for carrying excess liquids to said outlet ports.
Claim 7
Dependent Claim
98 words
The structure of claim 4 in which said side walls have outwardly projecting flanges adjacent their upper edges, and further comprising a relatively thin flexible membrane defining a top closure extending over said chamber and growth medium in overlying relation with said flanges, and fastener structure releasably securing said top closure to said flanges and including a pair of clamps respectively cooperative with said flanges for securing said top closure thereto, each of said clamps being a substantially continuous C-shaped member of substantially the same length as said flanges so as to extend from end to end thereof.
