Self-watering planter assembly

摘要

A self-contained, low-maintenance planter assembly used indoors or outdoors to provide prolonged self-watering of plants in a tray preferably supported by an easily height-adjustable frame insert positioned within the lower reservoir portion of a fluid-containing planter housing. Interior tray-lifting members are located adjacent to the tray's top edge, and the tray's bottom surface has perforations. Plant roots may be in growth/support medium distributed directly into the tray, or in drainable pots. Fluid-permeable material under the growth/support medium allows surplus rainwater to refill the planter housing via the tray's perforations in outdoor applications, while an overfill prevention hole in the planter housing prevents nutrient/liquid therein from entering the tray, with wicking member or members instead distributing nutrient/liquid upwardly to tray-supported plant roots. No tools or power/water connections are needed for assembly function. Applications include, but are not limited to, residential and commercial use, including hotels, convention centers, malls, and schools.

主权项

1. A self-contained and self-watering planter assembly providing reduced maintenance for container-grown plants, said planter assembly comprising:
a planter housing with an upper portion having a top edge, a bottom reservoir portion with a bottom interior surface, and at least one overfill prevention hole limiting a fluid volume of said bottom reservoir portion; a tray with a bottom surface having a plurality of perforations and a dimension allowing said tray to be positioned substantially within said upper portion of said planter housing, said tray also having a top edge and interior handle means adapted for lifting said tray and located adjacent to said tray top edge; a tray support sized and configured for positioning within said bottom reservoir portion of said planter housing, said tray support also having a top surface and downwardly converging legs positioned beneath said to surface, said tray support having a height dimension such that said top surface is positioned above said at least one overfill prevention hole in said planter housing, wherein said tray is supported only by said tray support; at least one layer of fluid-permeable material sized and positioned to cover said perforations in said bottom surface of said tray, said at least one layer of fluid-permeable material having at least one hole aligned with one of said perforations in said tray; and a plurality of wicking members with a different wicking member extending through each of said at least one hole of said at least one layer of fluid permeable material and the perforation aligned therewith, each said wicking member also having an upper end, a lower end, and a length dimension sufficiently large for extension between said tray and said bottom surface of said bottom reservoir portion of said planter housing and providing one-way transport of liquid from said planter housing to said tray, each said wicking member also having an additional length dimension on said upper end and positioning thereof allowing substantially even distribution of fluid within said tray, wherein once said tray support is placed within said planter housing, and said tray is lowered into said planter housing and positioned on said top surface of said tray support and situated substantially within the planter housing's upper portion, said fluid-permeable material covering said perforations in said tray allows excess fluid in said tray to move via gravity downwardly into said bottom reservoir portion of said planter housing, while said plurality of wicking members extending from said tray downwardly into said bottom reservoir portion draws fluid therein upwardly into said tray for continued self-watering of at least one plant supported by said tray without over-saturation of plant roots, with said at least one overfill prevention hole in said reservoir allowing exit of surplus fluid in said planter housing and preventing fluid in said bottom reservoir portion from moving upwardly and contacting said tray.
