A sliding engagement between the pair of mountings and first elongate element may be provided.
[0024] The position of the mounting or mountings on the first elongate element may be variable. It is particularly preferred that the mounting can be slid along the first elongate element. The mounting may be positioned on the first elongate element by means of a releaseable fastener, such as a bolt.
[0025] The second element portion may be retained within the mounting in the first state by means of a releaseable fastener, such as a bolt. The releaseable fastener may engage one or more second element portions, preferably a pair of second element portions on opposing sides of the first elongate element.

[0027] Preferably one or more of the work surfaces is a table surface. Ideally, the work surfaces are releasably fastened to the furniture support system. Preferably, the one or more work surfaces are reversible.
[0028] Preferably the lower surface of the work surface engages with the upper surface of the first elongate element and / or further elongate element or elements. A non-slip material may be provided between the work surface and the first elongate element / further elongate elements.
[0029] Various embodiments of the invention will now be described, by way of example only, and with reference to the accompanying drawings, in which:-
Figure 1 illustrates a plan view from below of a table support structure and table top profile;
Figure 2 illustrates the support system of Figure 1 in a state suited for transportation and / or storage;
Figure 3a illustrates a side view of the pivot brackets of Figure 1 and Figure 2;
Figure 3b illustrates a plan view of the pivot bracket of Figure 3a;
Figure 4 illustrates an alternative pivot bracket according to the present invention; and
Figure 5 illustrates a plan view of a support structure according to the invention illustrating a variety of possible features.
[0030] As illustrated in Figure 1, the invention provides a new manner for achieving a work surface support system. The support system consists of an upright 2 provided at each end of an elongate element 4. The uprights are of tubular form. A further upright 6 is provided at each end of the pivotally mounted elements 8. Again, the upright 6 is of tubular form. The elements 8 include a first elongate portion 10 which links the uprights 6 to a pivot location 12 and a second elongate portion 14 extending from the pivot location 12 to the end 16 of the elongate element 8 which is distal to the uprights 6. The whole of the element 14 is received within pivotal brackets 18 on each side of the elongate element 4, as described in more detail below.
[0031] In the supporting state, first state, illustrated in Figure 1, the support system provides good support for the work surface 20 by contact between the lower surface 22 of the work surface 20 and the upper surface of the elongate elements 4 and 8.
[0032] To facilitate storage and / or transportation of the furniture, the work surface 20 is readily de-mountable and the support system can be folded to a storage state, second state, as illustrated in Figure 2.
[0033] To achieve the transition from the support state to the storage state, releaseable fastenings attaching the elements 14 to the bracket 18 and / or element 4 are released. This allows the elements 10 to be swung towards the elements 4, whilst the elements 14 swing outward away from element 4, in both cases about the pivot locations 12. The net result is a support frame which assumes a low profile and volume in its storage state, but which provides effective support in its support state. Additionally this is achieved using pivoting locations which are hidden from the user and whilst employing a single leg at each of the more visible locations to the user.
[0034] As illustrated in Figures 3a and 3b, the pivotal bracket 18 is formed of a U-shaped cross section with planar and parallel upper and lower parts 30, 32 and perpendicular joining part 34. The element 14 of elongate element 8 is configured to be a very snug fit within the U-shaped channel, as illustrated by the dotted profile 36 in Figure 3a.
[0035] To restrain the element 14 in position in the bracket 18, a releaseable fastening, such as a bolt is passed through the element 14 and engages aperture 38 in the bracket 18 and / or a location in the elongate element 4. A common bolt or other releaseable fastening system could be used to fix both of two opposing elements 14 on the different elongate elements 8.
[0036] The pivotal mounting for the elongate element 8 on the bracket is provided by apertures 40 in the upper surface 30 and lower surface 32 of the bracket. These apertures cooperate with a pin or other suitable pivot which passes through and engages with the element 8.
[0037] As well as the style of bracket illustrated in Figures 3a and 3b, with one such bracket being provided on each side of the elongate element 4, other bracket configurations are possible. Thus, as illustrated in Figure 4, it is possible to provide a bracket 50 on each side of the elongate element 4 with those two brackets 50 being joined by a linking plate 52 which passes underneath the element 4. Apertures 40, define the hinges in the same way as described above, and aperture 38 provides a location to receive the fastener or the elongate element 8 and / or to fix the position of the pair of brackets 50 on the elongate element 4.
[0038] As illustrated in Figure 5 a variety of different extents for the elongate element 8 can be provided by varying the length of element 10 (10a is longer than 10b, for instance) and / or by varying the angle α separating the element 10 from element 14 of elongate element 8. Thus, an angle α of 120° may apply to elongate element 8b whereas an angle α of approximately 150 ° applies to elongate element 8c.
[0039] As illustrated in Figure 5, the brackets may provide hinge locations 12, as described above, together with locations 60 which receive the releaseable fasteners for fastening the elongate elements 8 to the brackets 18.
[0040] This embodiment of the invention also illustrates that the elongate element 4 need not be provided with uprights itself, all of the uprights potentially being provided on pivotally mounted elongate elements 8.
[0041] To provide increased flexibility the position of the pairs of brackets 18 on the elongate element 4 can potentially be varied by sliding the bracket assembly along the length of elongate element 4. Thus moving the pair of arms 8a and 8d towards the left hand side of Figure 5 would enable significantly longer work surface 20 to be supported.
