Abstract

ABSTRACT OF THE DISCLOSURE
Pots for flowers, plants, etc. made of monolithic concrete or similar settable material which are economical with respect to the amount of the concrete or similar material required and therefore relatively light in weight, have a center horizontal region which is hexagonal in outline, and an internal cavity of circular cross-section extending inwardly from the top, which is preferably in the shape of an inverted frustocone, and have the upper and lower parts of the exterior rounded off towards the respective tops and bottoms thereof, the rounding off extending substantially to the central horizontal plane at the edges of the hexagon.

Description

1066~56 The invention is concerned with a plant pot formed of concrete or other settable material as a monolithic, upwardly open hollow body with poly-gonal outline and essentially smooth outer surfaces.
Plant pots from concrete of various forms and styles are known.
They generally have a rectangular or round cross-section and are, depending on size, of different weights. With larger plant pots, it is known to build them on several frameworks by depositing in layers, whereby also variations in configuration are possible.
It is the problem of the invention to find a structure for mono-lithic plant pots which consist of a single part, which are easily made, and which do not have too great material consumption and consequently are not too heavy and which, in spite of these limitations, are aesthetically pleasing and make a great variability in an area possible, especially through the possibility of collecting several such plant pots in a group.
Accordingly, the invention provides a plant pot comprising a mono-lithic structure formed of concrete or similar settable material, said pot having therein a cavity of circular cross-section opening at the top, the exterior of said pot adjacent the middle horizontal plane thereof having a generally hexagonal configuration, the upper and lower outside edges of said pot being rounded off, and including means at the interior of the pot to receive a transporting device.
Thus, the invention solves the above problem by a plant pot which has, first of allJ a specific form of the shape of a hexagon in outline, with hollow space which is circular in cross-section and with the upper and lower exterior of the pot rolmded off toward the top and bottom. This rounding off preferably reaches approximately to the horizontal middle plane of the plant pot at the edges of the hexagonal structure.
The outer surfaces of the plant pot are approximately slightly ' Y
sloped in opposite directions towards the horizontal middle plane. In the outer surface, in the area of ~he horizontal middle plane, an annular groove ,,."~

.. ~.,' ,-~Q

:: ' lO~G056 can be provided. The hollow space inside the p]ant pot is appropriately~
according to the style, formed as an inverted truncated cone.
The plant pots of the invention have the advantage of an especially compact and variety rich exterior form which can readily be constructed of concrete. The outer edges are essentially rounded off so that they are largely insensitive against damage. Through the combination of the hexa-gonal form with the rounded edges and with the hollow interior o~ round cross-sectional shape, material and weight are economized and nevertheless i:
a form agreeable to the eye is attained.
Through the special construction of the plant pot, the further possibility exists that several of these kind of pots may be arranged in various dispositions with respect to one another, whereby at least an optical blending of the individual pots is produced according to the proportion of height to breadth or the proportion of rounding off of the individual pots which produces elliptical or circular outer surfaces.
Especially interesting groupings are produced if pots made according to the invention, are employed in different size arrangements. Thus, it is suitable to graduate the sizes according to a pattern, for example, with once, twice~ three times, etc., the length of a side.
In the inner wall of the plant pots, provision can be made for applying a transporting apparatus. Thus~ recesses may be arranged in two diametrical opposite places for the application of a transporting girder.
The advantages of these measures lie above all in that the transporting device can be inserted without the places on which the device is ; fastened appearing on the outside.
The invention will be further explained below with the aid of the exemplified embodiments shown in the drawing, wherein:
- Figure 1 is a three-quarter view of a plant pot;
Figure 2 is a plan view thereof;

igure 3 is a cross-sectional view ~aken on line III - III of Figure 2;
Figure 4 is a cross-sectional view taken on line IV - IV of Figure 2; and Figure 5 is a plan view of a group of differently sized plant pots of the invention.
Referring now to the drawings~ plant pot 1 is a monolithic~
"' :
hollow body open at the top, made of concrete or other settable material, as, for example, asbestos cement. It has, in outline, the form of a regular hexagon (Figure 2). A hollow space 2 in the interior of the pot formed of circular outline serves as the plant space for the reception of a cultivating substrate. It has the form of an inverted frustocone~ a sloping inner wall

3 and a bottom 4 which is ~omewhat sunken at the center part. In the center of the bottom 4, a threaded socket 5 is formed in which a pipe riser 6, for . .~, limiting the height of the water level~ can be screwed in.
From the inner wall 3, recesses 7 are provided on opposite sides of the body of the plant pot 1, in which a transport girder (not shown) can 'i be inserted. By means of the transport girder, the plant pot 1 can be shifted wlth the aid of a conventional lifting appliance.
The plant pot 1 is rounded off on the exterior at the upper edge 8 and at the lower edge 9. In the area of the edges of the hexagonal sides 10, the rounding off reaches up to the area of the middle plane X-X of the plant pot 1, as is indicated by Figures 3 and 4. The plant pot 1 thus attains a shape approximating that of a hexagonal nut. According to the proportion of the lateral length of the hexagon to the height of the plant pot 1 and to , the extent of the rounding off the remaining outer surfaces 11 are eliptical : ,,, ~: or circular in appearance ~see Figure 1).
~ The outer surfaces 11 are divided in the area of ~he horizontal i middle plane by a groove 12. The sur~aces 11' and 11" lying above and below .
, :,. . .

the groove 12 slope slightly away from the middle plane X-X (see Figure 4).
An illustration of the arrangement of such plant pots is shown in Figure 5 in plan view. Here, three different size types A, B, & C~ of plant pots are shown which are assembled to an irregular group. In these, the proportionate sizes have a definite relation to one another. Thus, the lateral length of the largest plant pot A amounts to twice that of the inter-mediate plant pot B and thrice that of the smallest plant pot C. Through the geometrically similar outline form, the individual plant pots can be set up in a space as a mosaic to ones liking.
The plant pots of the invention are first of all chosen and filled with soil or the like and planted with flowers, shrubs, trees, or the like.
At the same time~ transportable plant substitutes from plastic, wire baskets or the like find use, which receive the soil and can be exchanged without transporting the plant pots themselves.
The pots can also be used in various other ways, e.g. as well troughs, being provided with covers of wood or plastic, shaped as seating accommodations or with attached seats. By virtue of its hexagonal structure, a series of pots arranged one after the other, can be provided, e.g. for de-marking of footpaths and traffic areas, without producing boredom, since the side surfaces are always interrupted. When the plant pots do not stand side by side, they can be connected by rails, chains, ropes, or the like, as a barrier.
