Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
138 words
A constructional plant pot unit comprising a constructional unit having a plurality of radially extending pots arranged around a central hole defined by an upwardly extending and tapering tube, said pot being defined by convexedly radiussed outer parts and corresponding intervening concavedly radiussed interconnected parts whereby a pot of one unit can be mated with a concave part of a laterally adjacent similar unit, said unit having a base connecting said pots to said tube and each of said pots with recesses provided therein and adjacent said base with said recesses being arranged so as to seat upon the concave parts of a subjacent similar unit whereby at least a column of vertically aligned units may be built with each unit angularly off-set relative to subjacent or/and superjacent units and with laterally adjacent units of adjacent columns connected.
Claim 2
Dependent Claim
138 words
A constructional plant pot unit comprising a constructional unit having a plurality of radially extending pots arranged around a central hole defined by an upwardly extending and tapering tube, said pot being defined by convexedly radiussed outer parts and corresponding intervening concavedly radiussed interconnected parts whereby a pot of one unit can be mated with a concave part of a laterally adjacent similar unit, said unit having a base connecting said pots to said tube and each of said pots with recesses provided therein and adjacent said base with said recesses being arranged so as to seat upon the concave parts of a subjacent similar unit whereby at least a column of vertically aligned units may be built with each unit angularly off-set relative to subjacent or/and superjacent units and with laterally adjacent units of adjacent columns connected.
Claim 3
Dependent Claim
35 words
A constructional plant pot unit as claimeD in claim 1, wherein drainage holes are provided in each pot at a point where said tapered tube defining said central hole joins said base of said unit.
Claim 4
Dependent Claim
42 words
A constructional plant pot as claimed in claim 2, wherein cut-outs are provided in said base of said unit which cut-outs function to provide a circulation of air to growing media when filled within said central hole defined by said tapered tube.
Claim 5
Dependent Claim
55 words
A structure as claimed in claim 3 further comprising at least one additional plant pot unit, said units being arranged in the form of a column with each unit off-set angularly relative to subjacent or/and superjacent units whereby each pot is located in vertical alignment with a concave part of a subjacent or/and superjacent unit.
Claim 6
Dependent Claim
60 words
A structure comprising a plurality of columns of plant pot units as claimed in claim 4, said columns being arranged in the form of a wall with pots of each column of said units mating with concave parts of units of an adjacent column of said units and being connected by said grooves formed in said bases of said units.
Claim 7
Dependent Claim
46 words
A structure, as claimed in claim 4, including reinforcing means inserted through the vertically aligned central holes of said plant pot units, each said reinforcing means consisting of an apertured tube thereby to facilitate irrigation of growing media when filled into the pots of said units.
