Description
Background of the Invention
1. Field of the Invention
The present invention relates to a portable plant stand having a tapering support column and suspended shelves supported by the outer edges of the tapering support column.
2. Description of the Prior Art
One type of plant stand for supporting potted plants includes a vertical support column and horizontal shelves fixed at various positions along the support column. A plant stand disclosed in Slocum U.S. Pat. No. 163,417 includes a slightly tapered tubular metal support column with circular shelves attached by means of collars along the support column. The support column is hollow and perforated and a heat source is placed under the open lower end of the support column to heat the plants. Westphal U.S. Pat. No. 283,840 discloses another type of plant stand employing a slightly tapered tubular metal support column and horizontal shelves which are rotatably mounted on the support column. The support column also is mounted on casters.
The foregoing plant stands are formed principally of pre-formed metal components and appear to be expensive and complex, and not easily assembled and disassembled.
Summary of the Invention
In accordance with the present invention, an inexpensive and easily assembled portable plant stand for holding potted plants comprises a tapered support column including at least two interconnected elongated support members that extend upwardly from the bottom to the top of the support column and form the outer sides thereof. The support members are formed and interconnected such that the support column tapers inwardly as it extends from bottom to top. At least one shelf for holding plants is removably mounted on the support column. The shelf has an aperture therein that fits over the support column, the aperture being formed such that the tapered support column engages the sides of the shelf around the aperture and supports the shelf at a predetermined position along the support column.
The support column of the present invention includes a pair of opposed flat side members connected together by at least one flat center member that extends between the side members. The side members are releasably attached to the outer edges of the center member to permit easy assembly and disassembly of the support column. The side edges of the side members or the center member are tapered inwardly from the bottom to the top so that the support column tapers inwardly from bottom to top. Preferably, both the side members and the center member are tapered inwardly in this manner.
The shelves are supported on the support column by engagement of the edge of the shelf surrounding the aperture with the tapered outer surface of the support column.
The support column preferably is formed of three flat wooden members connected together so as to give the support column an H-shaped cross section. Each side member includes a pair of spaced cleats that hold the center member in a predetermined transverse position with respect to the side member. A single screw can be employed to attach each side member to the edge of the center member.
A base rail can be attached to the bottom of each side member for increasing the stability of the stand. Also, the support column can be mounted on a rotatable base assembly so that the entire plant stand is rotatable about a vertical axis.
The entire assembly can be fabricated from flat wooden pieces and packaged compactly for easy shipment. The support platform can be easily assembled and disassembled by means of two screws, one attaching each side to the center member. The shelves (which may be two or three shelves, depending upon the height of the support column) can then be mounted on the plant stand without any fasteners simply by placing the shelves over the top of the support column.
These and other advantages and features of the present invention will hereinafter appear, and, for purposes of illustration, but not of limitation, preferred embodiments of the present invention are described below and shown in the appended drawings.

Detailed Description of the Preferred Embodiments
Referring to the drawings, a plant stand 13 constructed in accordance with the present invention has a tapered support column 11 which is made from three members, a center member 10, a left side member 12, and a right side member 14. Each member is preferably formed of flat wood, with straight edges and plane surfaces, and is tapered inwardly toward its top. Each side member is atttached at the center of its inside surface to a side edge 22 of the center member 10 by means of a single screw 21. This makes assembly and disassembly of the stand an easy task and makes it possible to package the components of the stand in kit form in a compact, flat package. A bottom pair of spaced cleats 18 and a top pair of spaced cleats 16 are attached to the inside surfaces of the side members 12 and 14 abutting the center member 10 in order to properly position the center member with respect to the side members.
A cross-sectional view of the assembled support column resembles the capital letter "H" . At the bottom of the support column 11 is a base runner 20 attached to the outside surface of each side member 12 and 14. As shown in FIG. 3, the base runner 20 extends beyond the side edges of the side members 12 and 14 of the support column 11.
A bottom shelf 24 is mounted near the bottom of the tapered support column 11. As seen in FIG. 5, the bottom shelf has an octagonal outer configuration and has four circular openings 26 spaced around the shelf for holding potted plants. A rectangular aperture 28 is formed in the center of the shelf so as to fit over the support column. As shown in FIG. 6, two braces 34 are attached to the bottom surface of the shelf 24 adjacent opposite sides of the rectangular aperture. Bottom shelf 24 is mounted on the support column by fitting the shelf over the top of the support column 11 and moving the shelf downwardly to a point where the outer surfaces of the support column contact the edges of the central aperture 28. The braces 34 abut the side members 12 and 14 when the shelf 24 is wedged on the tapered support column and add to the stability of the shelf.
A top shelf 30 is also attached to the tapered support column 11 in the same manner as bottom shelf 24. The top shelf is of the same shape as the bottom shelf but is smaller than the bottom shelf. The upper shelf has a rectangular central aperture 32 for mounting the shelf on the support column and two circular openings therein for holding potted plants. The rectangular aperture 32 is smaller than the rectangular aperture 28 formed in the bottom shelf. As seen in FIG. 8, braces 35 are attached to the bottom surface of the shelf 30 and are aligned with two opposing edges of the rectangular aperture 32.
Top shelf 30 is mounted on the support column 11 in the same fashion as the bottom shelf 24. The outer plane surfaces of the side members 12 and 14 and its side edges will abut the braces 35 and the edges of the rectangular aperture 32 to rigidly support the top shelf 30. Due to the difference in size of the aperture 32, the top shelf will be supported near the top of the support column 11.
For convenience in handling and carrying the plant stand, an aperture or hand opening 36 is inserted through the top portion of the center member 10 of the tapered support column 11.
In another embodiment 40 of the invention, as seen in FIG. 9, a tapered support column 42 comprises side members 60 and 62 and center member 58 fastened together in the same manner as the sides and center member of support column 11. The principal difference between plant stand 40 and plant stand 13 is that support column 42 is taller than support column 11 in order to allow three shelves 50, 52, and 54 to be mounted on the support column with adequate space between the shelves. Another feature of the plant stand 40 is that the tapered support column is attached to a weighted rotating pedestal 56 instead of the runner base 20. The weighted rotating pedestal 56 allows the plant stand to revolve around its vertical axis so the position of the plants can be easily changed when desired. For example, when sun light is striking one side of the plant stand, the stand can be revolved to the side which is desired to receive the sunlight.
It should be understood that the foregoing embodiments of the present invention are merely illustrative of the preferred practice of the present invention and that various changes and modifications may be made in the arrangements and details of construction of the embodiments described herein without departing from the spirit and scope of the present invention.
