Description

WO 98/09556 PCT/AU97/00131 1 STAND ASSEMBLY FIELD OF THE INVENTION This invention relates to a stand assembly and in one preferred aspect relates to a stand assembly suitable for displaying and holding trays or shelves for supporting plants, wine bottles, books, store merchandise etc.

BACKGROUND TO THE INVENTION Numerous types of display assemblies have been proposed for merchandise. However, in the case of stands for plants, particularly display stands, the plants should be displayed in such a way that the different tiers of plants receive adequate lighting. Furthermore, it is important that the stand may be easily moved from place to place and that it can fit through narrow openings if it is necessary to move the stand around a premises or plant nursery. Thus it is preferable that the stand be foldable to ensure that its dimensions can be compressed in order to allow it to be moved through narrow apertures.

BRIEF SUMMARY OF THE INVENTION This invention provides a stand assembly, which comprises: a base to which is attached rotatably a framework for a set of stand platforms; and a location member for positioning the framework at selected angles, SUBSTTUTE SHEET (Rule 26) SrTIAT 9 7 00 RECEIVED 15 1998 2 wherein each platform is rotatably attached to the framework in such a manner that the rotatably attached framework produces a stable level condition in each of the platforms.

Accordingly, in one particularly preferred embodiment, the invention provides an adjustable stand assembly for mounting one or a plurality of stand platforms in a variety of aspect positions, said assembly including a base and an upwardly extending generally open framework for mounting said platforms wherein said base is adapted for generally horizontal placement on level ground and includes two substantially parallel spaced apart sides, said open framework includes two spaced apart side strut assemblies each strut assembly comprising a forward strut and a pair of telescopically cooperative rearward struts wherein said forward strut is pivotally engaged at or near a first end of a first side of said base and the internal rearward strut of said rearward strut pair is pivotally engaged away from said first end of said first base side wherein said forward strut and rearward external strut are bridged by one or a plurality of pivotally fixed transverse supports being adapted to engage said platform or platforms such that the telescopic adjustment of said rearward strut pair provides a coordinated adjustment of the angle of inclination of said platforms wherein said angle of inclination can be maintained substantially as the framework is pivoted relative to said base.

BRIEF DESCRIPTION OF THE DRAWINGS One embodiment of the invention is illustrated in the accompanying drawings in which: Figure 1 is a perspective view from one side and to the rear of the stand assembly according to the invention; RFigure 2 is a front view of the stand assembly shown in Figure 1; T 0

bTAJ9 7 0 0 1 RECEIVED 1 5 138 3 Figures 3A, 3B, 3C, 3D 'and 3E show differing platform and how they fit to the stand assembly; and Figures 4A, 4B, 4C, 4D and 4E correspond to Figures 3A, 3B, 3C, 3D and 3E (n part).

DETAILED DESCRIPTION OF THE DRAWINGS Preferably the base comprises a square or rectangular base frame, for example, a substantially flat 4-sided frame preferably supported by castors.

Preferably near one side of the base frame, for example, a longer side, is located an upwardly extending framework adapted to rotate from a substantially upright position to a substantially squat position.

The framework is preferably constructed from a frontward (as seen in use) strut and a substantially parallel rearward strut. The struts are preferably joined by a plurality of substantially parallel, substantially horizontal supports, each support being attached rotatably to its corresponding strut.

The framework is preferably supported by a prop member which preferably extends downwardly to the base frame and may be altered in a position with respect to the base frame, whereby the angular presentation of the framework may be selected.

Preferably the rotatable attachment of each rearward strut to the base frame is by means of a slot in the base frame allowing the framework sufficient slop in its movement to simplify rotation at other attachment points.

The trays may be shaped to hold objects of various shapes, for example, they Rmay be provided with depressions to accommodate pot plants.

-0 M&A ~7VT O) AM: NU 4 Two advantages of the stand assembly according to the inventor are: Firstly it will fold substantially flat for ease of transport; and Secondly, the tilt positions of the various shelves may be selected.

Turning to the accompanying drawings, Figures 1 and 2, a stand assembly comprises a base frame 11, which itself comprises two side girders 12 and 13 with rear and front girders, 14 and 15 arranged in the form of a rectangle. The base frame 11 is supported by casters 16', 16", 17', 17" at each corner of the rectangle. Plates 18 and 19 extend upwardly from side girders 12 and 13 respectively. Two corresponding series of indents such as 20', 20", 20"' etc are let into the upper portions of each plate 18 and 19.

An upwardly extending framework 21 comprises two forwardly mounted (as viewed in use) struts 22' and 22" and two rearwardly mounted strut pairs 23' and 23" both rotatably attached to plates 18 and 19 respectively. Each rearward strut pair is made up of an internal strut and a telescopically mounted external strut 23'. The struts 23' and 23" are joined by transverse (as viewed in use) supports 28', 28", as are struts 22" and 23" by other supports (unnumbered). A U-shaped stay 25, 26, 27 is pivotally attached to strut 22' and 22" and fits into the corresponding series of indents 20', 20", 20"' etc.

Finally, a pivot member provided with a spigot or wheel 29 is shown projecting through a slotted groove 30 in plate 18 to provide the requisite amount of movement to allow the framework to fold down.

The corresponding strut 23" is also supplied with a pivot member which fits into the corresponding plate 19.

The fixed front pivot is formed at a raised position on the base side relative to the slot 30 so to allow the frame work to completely fold flat against the base.

This clip is used as a locking means to maintain the strut in position. The corresponding clip on the strut 23' has not been shown.

Figure 2 shows the relationship of platforms 31', 31" and 32" In Figures 3A, 3B, 3C, 3D and 3E, various types of platforms are shown. Thus, platform 40 has a generally rectangular framework 41 with slots 42' and 42" at opposite ends. Numeral 43 indicates one of a series of pot holders. Platform 44 and 45 have different series of pot holders. Platform 46 has a flat bottom 47. Platform 31' has a mesh bottom 47.

Figures 4A, 4B, 4C, 4D and 4E correspond to Figures 3A, 3B, 3C, 3D and 3E (in part).
