Abstract
Abstract Apparatus for forming an above ground bed in which plantlife may be grown and for irrigating the bed. The apparatus comprises a plurality of modular members arranged to be readily connected to one another to form a walled enclosure disposed on the ground. The enclosure is arranged to be filled with a plant growing medium, e.g., soil, to form the bed. Each of the members is an elongate hollow body having a pair of ends. At each end is a releasable connector portion which is arranged to releasably connect the members to one another at various angles to form enclosure of various shapes. Each of the members includes an inner wall having a plurality of small apertures which are in communication with the hollow interior of the member. At least one of the members includes a fitting for a hose to enable water to be introduced therein. The connectors include couplings which allow water introduced into one member to flow into the other members, whereupon the liquid may slowly seep out of the apertures and into the bed to irrigate the bed. The members also include openings extending through them to enable them to be staked to the ground. A recess is provided in the top wall of each member at one end thereof to enable auxiliary structures, e.g., trellises, frames, etc., to be mounted thereon. The staking openings can also be used for mounting the auxiliary structures.

Total Claims: 15
Claim 1
Independent Claim
261 words
Apparatus for forming an above ground bed in which plant life may be grown and for irrigating said bed, said apparatus comprising a plurality of modular members and releasable connecting means therefor, said members being arranged to be readily connected to one another by said releasable connecting means to form a walled enclosure disposed generally horizontally on the ground, said enclosure being arranged to be configured in various shapes and to be filled with a plant growing medium to form said bed, each of said members comprising an elongate hollow body having a pair of ends, said releasable connecting means being located adjacent each of said ends, each of said releasable connecting means comprising generally vertically oriented conduit means and ring means releasably disposed about said conduit means, said ring means and said conduit means cooperating with each other and with two of said members to releasably pivotally connect said two of said members to each other at any one of various angular orientations with respect to a vertical axis extending through said conduit means to form an enclosure of one of said various shapes, said conduit means introducing a liquid into the interior of one of said two members from the other of said members to which said one member is pivotally connected, each of said members including a plurality of small apertures in communication with the hollow interior of said member, whereupon said liquid may flow through said conduit means from one member to another and slowly seep out of said members into said bed to irrigate said bed.
Claim 2
Dependent Claim
