Abstract

A versatile yet highly simplified and exceptionally utilitarian plant growth apparatus assembly is comprised of a combination, in desired practical plurality, disposition and geometry and arrangement, of several individual and self-contained functional units and structures that are modular in nature and applicability and cooperable for engagement and association with one another so as to constitute the wanted and/or necessary resultant effective and operable assembly; the modular units being severally and characteristically in the nature of either mechanical structure members and/or environmental control systems electrical or otherwise in nature and/or light-providing components; the several said units further being peculiarly adapted for very quick and easy mounting and construction into, change and alteration within, addition to or disassembly from the structured apparatus assembly.

Claims

1. Plant growth apparatus for use in artificial light horticulture comprising a plurality of modular elements adapted to be quickly and easily assembled into an integral structure and wherein the relative dispositions of said modular elements within said structure can be readily altered, which apparatus comprises:

a. a pair of upright substantially vertical support columns;

b. internal support means disposed between said vertical columns to laterally space and rigidize said vertical columns into a base frame;

c. laterally extending leg portions affixed at the bottom of each of said vertical columns to support said base frame in generally upright fashion;

d. receptive connecting means at corresponding spaced intervals on the laterally outward face portions of said vertical columns;

e. at least a pair of laterally extending shelf support brackets having fastening means at their inner ends adapted to be fastened into said receptive connecting means on said vertical columns, each pair of brackets being respectively disposed one on each of said columns at the same vertical position on the same face side of the columns;

f. an elongate, multiple outlet electric power strip energized by a single external power feed line connection positioned vertically on one of said support columns and extending vertically on said column for at least a portion of the column height, with at least one of the electric outlets in said strip being closely adjacent the fastening point of each of said shelf support brackets disposed on said column;

g. at least one generally rectangular light-providing shelf unit substantially horizontally disposed upon each pair of said laterally extending support brackets, said light-providing shelf unit comprising;

i. a flat upper surface adapted to hold plant materials and other objects as a shelf area,

ii. an open under section containing laterally disposed therein at least one fluorescent tube light, the area beneath said open under section defining a plant growth area which is substantially as wide as the distance between said column supports, and

iii. end encasement sections extending longitudinally outwardly from said open under section, said encasement sections containing the ballast units and other electrical circuitry for the fluorescent light operation, and wherein said shelf support brackets engage said light-providing shelf unit outside said plant growth area at said end encasement sections.

2. The apparatus of claim 1 wherein said power strip is contained within one of said vertical columns.

3. The apparatus of claim 1 additionally comprising roller means on said laterally extending leg portions to permit movement of the apparatus.

4. The apparatus of claim 1 additionally comprising an electric current timer device capable of opening and closing the external power feed of said power strip in order to automatically control in predetermined sequence the light supply to said plant growth area.

5. The apparatus of claim 1 additionally comprising a rotatable, generally cylindrically arranged clinestat positioned between said vertical columns and wherein at least one of said light-providing shelf units projects over said clinestat in a spaced, generally tangential plane relative to said clinestat.

6. The apparatus of claim 5 wherein at least two of said light-providing shelf units are positioned tangentially over said clinestat on opposite sides of said vertical columns.

7. The apparatus of claim 1 wherein at least one of said light-providing shelf units is substantially vertically disposed at the extremity of at least one pair of said laterally extending shelf bracket supports.

8. The apparatus of claim 1 additionally comprising an unlighted base shelf unit positioned under at least one of said light-providing shelf units on at least one side of said vertical support columns.

9. The apparatus of claim 8 having at least two of said unlighted shelf units and at least two of said light-providing shelf units and wherein at least one of each of said units is supported on opposite sides of said vertical columns.

10. The apparatus of claim 8 wherein at least two of said light-providing shelf units are supported on said vertical columns one over the other.

11. The apparatus of claim 8 wherein at least two of said light-providing shelf units are supported on said brackets in a laterally extending, side-by-side relationship.

12. The apparatus of claim 8 additionally comprising at least one transparent box-like, plant growth enclosure curtain suspended from one of said light-providing shelf units to enclose the plant growth area beneath said shelf unit.

13. The apparatus of claim 12, wherein said enclosure curtain comprises a five-sided open-bottomed box of a transparent, flexible plastic material with its dependent sides being unattached to one another at the vertical side edges.

14. The apparatus of claim 13 wherein said enclosure curtain has reflectorized inner side wall surfaces.

15. The apparatus of claim 8 additionally comprising at least one flexible transparent sheet having a reflectorized inner surface suspended from an outer lateral edge of at least one of said light-providing shelf units and extending down to an immediately adjacent lower shelf unit.

16. The apparatus of claim 15 wherein said reflectorized sheet is suspended by and suppliable from a window shade roller type device.

17. The apparatus of claim 8 additionally comprising means for plant growth irrigation.

18. The apparatus of claim 8 additionally comprising means for plant growth humidification.

19. The apparatus of claim 1 wherein at least two of said light-providing shelf units are supported on said vertical columns one over the other.

20. The apparatus of claim 1 wherein at least two of said light-providing shelf units are supported on said brackets in a laterally extending, side-by-side relationship.
