The table assemblies find particular application in a function or hospitality environment. The present invention also extends to accessories, particularly elevation stands for supporting an object for display on a table surface.

0 o Background of the invention 0 There are many situations, particularly in the function or hospitality environment, where a large number of tables are required to be temporarily set up for use and then packed away for storage. There is a requirement to be able to do this as quickly as possible with a minimum number of staff.

The traditional tables used in these situations are known as trestle tables. Trestle tables have a flat table top with depending legs that are permanently attached to the bottom surface of the table top. The legs are pivotable and when folded lie flat against the bottom surface so that the trestle tables can be stacked together when not in use.

One of the main problems with trestle tables is that they can accidentally fold when knocked from one end. However, providing complicated means for locking the legs contributes substantially to set up and disassembly time.

Another problem with trestle tables is that their appearance is quite unattractive in formal or professional settings. it is therefore standard practice to drape the tables with table cloths. This of course adds to the time required to set up a room full of tables and to clear the room. Additional cost is incurred for laundering the table cloths.

It is therefore an object of the present invention to provide an improved table assembly that alleviates some of the problems with current tables for this purpose and achieves a balance between efficiency of set up and disassembly time, stability and appearance.

o A table assembly 10 is provided that includes a removable table top 12 having respective generally flat main surfaces 14, 16. In the embodiments shown in Figures 1, 2, 6-10, the main surfaces 14, 16 may have different finishes such that the appearance of the table assembly 10 can be changed by flipping the table top 12. In another form, o table top 12 may be glass or otherwise transparent. A supporting structure 18 is used to r- support the table top 12 when in the assembled position, as best shown in Figures 1, 2 o 10 and 6. As shown in Figure 1, two supporting structures 18 may be used to support a single table top 12 of greater length.

The supporting structure 18 includes at least two frames 20a, 20b, each frame has two upright legs 22 connected by horizontal members 24, 26 adjacent the respective ends 28, 30 of the upright legs 22. It can be seen from the Figures, the ends 28 engage the ground and the table top 12 rests on the ends 30 of upright legs 22.

However, it will be appreciated that the supporting structures 18 shown are symmetrical about a horizontal central plane and therefore may be orientated with either ends 28 or ends 30 engaged with the ground. This allows the set up of the table assemblies to be accomplished quickly, as ensuring correct orientation of the support structures 18 is not required.

The frames 20a, 20b are mutually articulated about a vertical axis 32, best shown in Figure 4. The two frames 20a, 20b are coupled, at a position intermediate the respective ends 34, 36 of the horizontal members 24, 26, by vertical pins 38. As can be seen in Figures 3 and 4, the frames 20a, 20b pivot about the vertical axis 32 with respect to each other between an expanded position (Figure 3) for supporting the table top 12 and a collapsed position (Figure 4) for storage.

The table tops 12 are removable, such that they can be stacked separately to the supporting structures 18. The table assemblies 10 can be stored on trolleys, the supporting structures 18 hang on racks, with the horizontal members 26 hooking over arms on the trolley so as to be suspended.

COMS ID No: ARCS-170960 Received by IP Australia: Time 16:58 Date 2007-12-03 03/12/2007 16:53 freehills 12345678 9/23 005060024 o In the embodiments shown in Figures 1 to 5, the supporting structure 18 does not extend past the perimeter 40 of the main surfaces 14, 16 and is therefore neatly hidden beneath the table top 12.

oAs can be seen from the different embodiments shown in the drawings, the supporting structures may have relatively short horizontal members 24, 26 as shown in lN Figures 1 and 2 creating a substantially square arrangement of the upright legs 22. In this case, two supporting structures 18 are used to support a long table top 12.

o Alternatively, the horizontal members 24, 26 may be long, as shown in Figure 3, such that one supporting structure 18 is used to support a long table top 12. For ease of manufacture and aesthetic reasons, the upright legs 22 in this embodiment typically Chave a circular cross-section and may be made from tubular steel. The horizontal members 24, 26 typically have a rectangular cross-section and may be box section steel.

To set up the table assembly 10 shown in Figure 2, the supporting structure 12 is stored in the collapsed position and is lifted off the trolley and set on the ground with ends 28 of the upright legs 22 on the ground. One of the frames 20a is then pivoted with respect to the other frame 20b, until a projection 42 on horizontal member 26a abuts against horizontal member 26b to limit the angular expansion of the supporting structure 18. The table top 12 is then lifted and sat on top of the ends 30 of the upright legs 22.

In the embodiment shown in Figure 3 to 5, the table top 12 includes four recesses 44 contained within fixtures 46. The fixtures are preferably stainless steel and are inserted into pre-drilled hollows 48 in main surface 14 so as to be flush. The ends of the upright legs 22 positively engage in the recesses 44 to stabilise the supporting structure 18 in the expanded position. The table cannot be accidentally knocked over, as the table top 12 must be lifted to disengage the ends 30 of the upright legs 22.

In the embodiment shown in Figures 6 to 8, each upright leg 22 includes a seat in end 30. The upright legs 22 have a rectangular cross-section and a corner is cut away to create a horizontal surface 52 and a vertical surface 54. The table top 12 rests on the seat 50, with the main surface 14 engaged with horizontal surface 52 and the perimeter, or edge, 40 of the table top 12 engaging with the vertical surface 54, thereby COMS ID No: ARCS-170960 Received by IP Australia: Time 16:58 Date 2007-12-03 03/12/2007 18:53 freehlIs 12345678 10/23 005060024 6 O stabilising the supporting structure 18 in the expanded position. Similar to above, the 0 N table cannot be knocked over accidentally, as the table top 12 must be lifted to Sdisengage the ends 30 of the upright legs 22.

The advantage of the embodiment shown in Figures 6 to 8 is that the supporting structure 18 can be expanded by pivoting the frames 20a, 20b to where the horizontal Cmembers 24, 26 lie perpendicular to one another. The table top 12 can then simply be dropped into place on the seats 50. The table top 12 can have different finishes on the 2main surfaces 14, 16 to create two different aesthetically appealing looks. The different finishes may be two different colours, so that all tables in a room are the same colour or may alternate.

A variation of the embodiment shown in Figures 6 to 8 is shown in Figures 9 and The upright legs 22 have a cut away angle to create the seat 50 with one horizontal surface 52 and two vertical surfaces 54. The corners 60 of the table top 12 engage in the seats 50 to stabilise the supporting structure 18 in the expanded position.

A tablrassembly 1?r ade according to any of the aspects of the present invention is easily and quickly assembled by a single person. The simplicity of the appearance makes it suitable for any function, without the table top being draped. In some forms of the invention positive engagement between the supporting structure and table top prevents accidental collapsing of the table assembly, whilst providing easy and simple engagement and disengagement for setting up and storage.

Figures 11 to 13 show another aspect of the invention, being elevation stands 200. Elevation stands 200 are used for supporting an object for display on a table surface 212, such as plates, bowls etc (not shown) for serving food. The table surface may be part.of a table assembly according to one of the embodiments shown in Figures 1 to 11. The table assemblies and one or more elevation stands 200 may form a matching set for functions, as shown in Figure 12.

The elevation stands 200 include at least two frames 220a, 220b each having two upright legs 222 connected by at least one substantially horizontal member 224, COMS ID No: ARCS-170960 Received by IP Australia: Time 16:58 Date 2007-12-03 03/12/2007 16:53 freehills 12345678 11/23 005060024 7 O whereby the object rests on the end 230 of the upright legs or on the substantially 0 N horizontal members 224; 0The frames 220a, 220b are mutually articulated about a vertical axis by coupling the horizontal members at a position intermediate their respective ends 234, 236, such that the frames 220 pivot about the vertical axis with respect to each other between an cexpanded position for supporting the object and a collapsed position for storage.

As can best be seen in Figure 13, the upright legs 222 may be constructed in at least two longitudinal sections 260, 261 that clamped together to retain an end 234 of a o horizontal member 224 between two sections 260, 261. As can be seen in Figure 12, c- 10 the frames 220 may include two horizontal members 224, 226. In this embodiment there is included three longitudinal sections 260, 261, 263 to clamp the horizontal member 224 between sections 260 and 261 and to clamp the horizontal member 226 between sections 261 and 263.

The longitudinal sections 260, 261 each include an internal thread 262 and the end of the horizontal members 224 include an aperture 264, whereby a threaded connector 266 is inserted through the aperture and into the internal threads 262 of the longitudinal sections 260, 261, which are tightened, as illustrated in Figure 13 to clamp the horizontal member 224 between two sections 260, 261.

A vertical pin (not shown) may be used to couple the horizontal member 224a of one frame 220a to the horizontal member 224b of another frame 220b. This is best illustrated in Figure 11. Preferably, the vertical pin is threaded and is received in an internally threaded stopping member 268 that clamps against the lower horizontal member 224b to prevent movement of the frames 220.
