Background to the Invention Furniture and, in particular, desks for information technology equipment, school furniture, office furniture and laboratory furniture generally comprises square or rectangular desks having a support leg at each corner thereof. Each leg has two support struts which extend perpendicularly to each other in order to support the desk surface. In certain situations, it may be required to have the desk arranged in a non-linear fashion, for example against an undulating wall. With conventional desks this may be unsightly due to the edges of the desks appearing to be haphazardly arranged. Similarly, when rooms, for example, computer rooms are rearranged, the new arrangement may require different shaped support surfaces.

Accordingly, this requires new furniture to be purchased to fit the required shape.

In addition, if a desk is required to have a irregular shaped desk surface then a special frame must be built which is time consuming and expensive since it may only be required for a single situation or location.

Alternatively, a standard square or rectangular support frame may be used which does not evenly or properly support the desk top and any items thereon.

Furniture for technology equipment, and in particular computers printers etc. generally have a number of wires associated therewith. Such wires are unsightly and can also be difficult correctly to identify which cable is which, for example in a large computer room or cyber cafe the number of wires may cause problems especially if the arrangement of the furniture is to be changed. In addition, in publicly accessible areas it is advantageous to hide and prevent access to any cables to prevent any misuse, either accidental or intentional, to the equipment.

It is an aim of the present invention to overcome at least one problem associated with the prior art whether referred to herein or otherwise.

Description of the Preferred Embodiments As shown in Figure 1, adjustable furniture support apparatus 10 comprises a support leg 12 and retaining means in the form of a retaining member 14 which is arranged to retain a support member 16 to the support leg 12. The support member 16 is arranged to extend radially away from the longitudinal axis of the support leg 12 and the support leg 12 is arranged, in use, to be in a substantially vertical plane whilst the support member 16 is arranged to be in a substantially horizontal plane.

Accordingly, the support member 16 is substantially perpendicular to the support leg 12. The support leg 12 has a foot 22 provided at the lower end thereof to be supported on the floor or ground. The foot 22 may be adjustable and can be screwed into or out of the support leg 12 in order for the height of the support leg 12 to be adjusted.

As shown in Figure 3 and Figure 4, an item of furniture, for example a desk 18 or table, comprises a number of support legs 12 and support members 16. Each support leg 12 retains and support two support members 16. Each support member 16 extends from a first support leg 12 to a second support leg 12. Accordingly, the item of furniture includes four support legs 12 and four support members 16.

As shown in Figure 4, the support members 16 are arranged to support a support surface 19 thereon. The support surface 19 (as shown in Figure 6) may simply be rested on the support members 16 but preferably securement apparatus 80 for the support surface 19 is preferably used. The securement apparatus 80 will be described in more detail later.

As shown in Figure 1, Figure 2 and Figure 17 to 21, the retaining member 14 comprises a collar secured at an upper end of the support leg 12. The collar may be a discrete member which is secured to the leg. The collar has an outer surface which is generally cylindrical. The outer surface has a plurality of retaining grooves 24 provided thereon. Accordingly, the outer surface comprises a profiled or keyed surface. The grooves are spaced around the periphery of the collar and are spaced at angled increments, 0 and preferably at 15° increments.

The support member 16 has a retaining flange 26 defined at a longitudinal end thereof. The retaining flange 26 is arranged, in use, to locate with a retaining groove 24 of the collar in order to retain the support member 16 to the support let at a selected angle about the longitudinal axis of the support leg 12. Accordingly, the retaining member 14 enables the support member 16 to be retained to the support leg 12 at a selected an adjustable angle about the longitudinal axis of the support leg 12. Since the retaining grooves 24 are provided at 15° increments, this enables two or more support members 16 to be retained at a selected angle relative to each other, although this angle may be dictated by the increments. The 15° incremented

grooves enables the popular and frequent angle of 90° to be easily achieved whilst also enabling other popular angle such as 30°, 45°, 60°, 180° etc and all other multiples of 15°. Accordingly, the adjustable furniture support apparatus 10 can be used to support difficult shaped support surfaces 19 and to create different shaped desks etc. For example, regular polygon shaped desks irregular polygon shaped desks, (as shown in Figure 7) square, rectangular, triangles, pentagon, hexagon, octagon, etc, shaped desks and also other trapezoidal shaped desks.

The retaining grooves 24 are shaped to prevent removal of the retaining flange 26 from the retaining groove 24 and in particular the prevent movement of the support member 16 along the longitudinal direction of the support member 16. The retaining flange 26 is inserted into the retaining groove 24 by locating the retaining flange 26 above the retaining groove 24 and then sliding the support member 16 and hence the retaining flanges 26 into the retaining groove 24. This movement is along the longitudinal direction of the support leg 12 and also the longitudinal direction of the retaining groove 24 and the retaining flange 26. The shape of the retaining groove 24 and the co-operating shape of the retaining flange 26 thereby prevents the retaining flange 26 from being removed from the retaining groove 24 by pulling the support member 16 along its longitudinal axis. Each retaining groove 24 has a retaining portion and a mouth portion with the retaining portion retaining the retaining flange 26 therein whilst the mouth portion preventing the retaining flange 26 passing through the mouth portion.

Similarly, the retaining flange 26 comprises a retaining

portion and a neck portion. The securement of the retaining flange 26 in a retaining groove 24 is shown in Figures 18 to 21.

The retaining grooves 24 are tapered from the upper end to the lower end as shown in Figure 17. Similarly, the retaining flange 26 is tapered from an upper end to a lower end as shown in Figure 18. Accordingly, as uhe retaining flange 26 is moved downwardly the retaining groove 24 securely grips or retains the retaining flange 26. The tapered retaining flange 26 and tapered retaining groove 24, once assembled, prevent or inhibit relative movement therebetween and especially in directions not along the longitudinal direction of the support leg 12.

This results in the join being secure and without rocking movement which may be present in conventional furniture joins. Conventional furniture joins may rely on the manufacturing tolerances between the joins which may be expensive to prevent rocking or the furniture may be cheap and thereby is at risk from rocking. The tapered flange 26 may also have a projection 25 at the lower end thereof to locate in a recess 27 at the bottom of the tapered groove 24 in a fully interlocked position.

The retaining flange 26 can only be removed from the retaining groove 24 by reversing the insertion movement i. e. moving the retaining flange 26 upwards relative to the retaining groove 24.

The retaining means comprises a plate or cover 30 which is arranged to be located over the upper surface of the retaining member 14. The cover 30 thereby prevents the

retaining flanges 26 from being removed from the retaining groove 24.

The cover 30 is secured to the retaining member 14 by a securement element 32 or elements in the form of a screw (s) or bolt (s). The cover 30 is circular and is arranged to co-operate with an upper end edge or the longitudinal end of the support member 16, for example the upper end edge 40 of the support member 16 may be arcuate.

Accordingly, this conceals any gap and creates a good join. As the cover is screwed or otherwise urged downwardly on to the upper end of the support leg the tapered flanges 26 are urged into the tapered groove 24 to provide a secure join.

Furthermore, a first longitudinal end of the support member 16 has an arcuate or cylindrical end surface 42 to co-operate with the outer surface of the retaining member 14 as shown in Figure 2. The longitudinal end (s) or longitudinal end face (s) 42 are tapered inwardly from an upper end to a lower end as shown in Figure 1, Figure 3 Figure 7 and Figure 17 to Figure 21a. The sides 6,7 of the longitudinal end faces 42 are curved and more particularly are convex. This shape further provides a strong join between the support member and the support leg. In addition, the support member 16 itself is tapered along the longitudinal extent thereof towards the longitudinal end, as shown in Figure 2.

The retaining portion of the retaining flange 26 is generally circular or cylindrical and is tapered from an upper end to a lower end. Similarly, the retaining portion of the retaining groove 24 is generally

cylindrical or circular in cross-section. As previously explained, the retaining flange 26 and the retaining groove 24 are both tapered.

Since the retaining member 14 enables a plurality of support members 16 to be retained therefrom, each leg may be arranged to support more than one support surface 19, as shown in Figure 5. For example, if two desks IS are to be placed adjacent to each other, rather than each desk 18 having a full set of four legs, where the desks 18 are adjacent, a single leg could be used in order to retain support members 16 for more than one desk 18.

Accordingly, this substantially reduces the amount of equipment required and thereby reduces the cost.

Similarly, each support member 16 may be arranged to support two adjacent support surfaces, as shown in Figure 5.

As shown in Figure 8 and Figure 9, the support leg 12 may be provided with a base 38. The base 38 is arranged to support the support leg 12 on the floor and may enable the support leg 12 to be a free standing unit. The base 38 extends radially around the longitudinal axis of the support leg 12.

The base 38 may extend through between 135°and 170around the longitudinal axis of the support leg 12.

In an alternative embodiment, the base 38 may be arranged to provide a free standing leg in order to support a support surface 19 thereon, i. e. a single support leg 12 may be arranged to support the support surface 19. The retaining member 14 of the support leg 12 may be arranged

to have a number, for example three or four support members 16 extending outwardly (e. g. radially outwardly), therefrom. This arrangement may be arranged to provide a pedestal table. Accordingly, the base may extend the full 360° around the longitudinal axis of the support leg 12.

As shown in Figure 9. Figure 10 and Figure 11, the support leg 12 may be arrangea to support a monitor directly thereon and also to support a support surface 19. Two support legs 12 may be arranged to support the support surface 19 therebetween. Since only two support legs 12 are used, with each support leg 12 supporting two support members at generally 180° relative to each other (not shown) this provides economic and space saving furniture.

In addition, a row of desks can be arranged to be non- linear, for example to be aligned with a non-linear wall and in particular may provide a row of desks and monitors for use in a cyber cafe or computer room.

The support leg 12 has a passageway defined therethrough which preferably extends through the longitudinal length of the support leg 12. The passageway may enable cables to pass therethrough and, in particular, enables cables for information technology equipment to pass therethrough, for example cables for computer, printers and monitors etc. In addition, the support leg 12 may have a socket 44 or sockets to enable external cables to be plugged in, as shown in Figure 11. An internal cable may be provided which may extend through the passageway to the upper end or desk 18 surface or to another socket. The support leg 12 may have an actuating switch 46 associated with the or each socket in order to turn the socket on or off. In addition, the support leg 12 may have a removable and

replaceable cover 46 to provide access to the passageway through the support leg 12 as shown in Figure 8.

As shown in Figures 12 to 14 and Figure 22, the retaining member may comprise two annular (or cylindrical) members 62,64. The support member 16 has an annular member 62 or 64 secured thereto, for example, the annular member 62 or 64 may be integral with the support member 16. A first support member 16'may have a lower annular member 62 secured thereto whilst a second support member 16"may have an upper annular member 64 secured thereto.

The lower annular member 62 is arranged to locate over a retaining surface provided by a boss 60. The boss 60 provides an outer generally cylindrical retaining surface.

The retaining surface is tapered outwardly from the upper end thereof, i. e. the cross-section of the boss extends outwardly from the upper end to the lower end. Similarly, each annular member 62,64 has an inner retaining surface which is tapered outwardly from an upper end to a lower end. In particular, the retaining surfaces of the boss and the annular members 62,64 are arranged at an angle, a, which may be in the region of 1-5° and preferably is substantially 1. 5°.

In use, the lower annular member 62 is located over the boss in order to support a first support member 16'at an angle about the longitudinal axis of the support leg 12.

The upper annular member 64 is then located over the boss in order to support a second support member 16"at an angle about the longitudinal axis of the support leg 12.

The first support member 16'can then be rotated, about the longitudinal axis of the support leg, relative to the

second support member 16"in order for the first support member 16'to be located at any predetermined angle relative to the second support member 16".

A cover 30 is located on to the upper end of the boss 60 and is secured thereto by a securement element 32. The securement element 32 is arranged to urge the cover 30 downwards which thereby urges the upper annular member 64 and the lower annular member 62 downwards. This forces the retaining surface of the annular members 62,64 to abut and to be urged against the retaining surface of the boss 60. This prevents the support members 16', 16"from being rotated about the boss 60 and therefore locks the support members 16', 16"in position.

In-order to adjust or reconfigure the furniture, the securement element 32 can be loosened to enable the first support member 16'and the second support member 16"to be rotated about the boss 60 to another relative angle to provide support means for a support surface 19.

Accordingly, this embodiment enables the support members 16', 16"to be at any angle relative to each other.

In alternative embodiments, the boss 60 may be arranged to support one or more than two (for example four) annular members in order to support the corresponding number of support members.

As shown in Figures 1,15 and 16, securement apparatus 80 for a support surface 19 comprises an engagement portion 82 which is arranged to locate in an opening or engagement groove 84 provided along the support member 16.

Accordingly, the support member 16 provides a support

rail. The engagement portion 82 is provided on an engagement arm 86.

The securement apparatus 80 comprises a retaining member 88 and a securement member 90. The retaining member 88 provides a housing or surface in order for the securement member 90 to locate adjacent thereto.

In use, the engagement portion 82 is located in the groove 84. In performing this, the engagement portion 82 is flexed downwards whilst being pushed into the retaining groove. Once in the specified position in the groove 84, the engagement portion 82 flexes upwardly to locate in a recessed portion 100 in the groove 84.

An abutment surface 92 of the retaining member 88 abuts and locates on the upper surface 94 of the support member 16. A co-operating portion 96 of the retaining member 88 also locates in the groove 84. As the securement member 90 is located into the housing or surface provided (for example a shaped surface) in the retaining member 88, a securement or locking arm 98 secures or locks the securement member 90 to the retaining member 88 and hence to the support member 16. The securement member 90 comprises a co-operating member 106 which interlocks with an interlocking portion 108 provided on the retaining member to help to retain the securement member 90 adjacent to the retaining member 88.

As can be seen in Figure 16, the groove 84 comprises a recessed portion 100. The engagement portion 82 is moved into the recessed portion 100 in the secured position.

This thereby prevents the engagement portion 82 from being

removed from the groove 84 and hence the securement apparatus 80 is secured to the support member 16. In the fully secured position, a locking surface 102 on the securement member 90 or locking arm 98 engages with a locking surface 104 on the engagement arm 86.

The securement member 90 is secured to the lower surface of tne support surface 19, for example by adhesive means which may comprise an adhesive tape or glue. The securement member 90 is secured to the support surface 19 prior to the locating the securement member 90 adjacent to the retaining member 88. In use, a plurality of securement members 90 are secured to the underside of the support surface 19 at predetermined locations.

Corresponding retaining members 88 are then secured into the grooves 84 provided by the support members 16 for the support surface 19. The support surface is then lowered on to the support members 16 in order for the securement members 90 to be secured to the retaining members 88 which are already secured to the support members 16.

The support surface 19 is locked to the support members 16 since the securement or locking surface 102 of the securement member 90 engages the locking surface 104 on the retaining member 88.

The securement apparatus 80 may act in pairs in order for one securement apparatus to secure one edge of the support surface 19 whilst the second support apparatus secures a second opposite edge of the support surface 19.

The securement member 90 provides a support surface 110 in order to support the support surface 19 of the desk 18.

Alternatively or additionally, the retaining member 88 may also provide a support surface. The support surface of the securement member 90 may have a projecting portion 91 in order to project into a recess provided in the lower surface of the support surface 19. This may provide alignment means to enable the locking members 90 to be correctly positioned relative to the outer edge of the support surface 19 in order for-the locking surface 1-02 of the securement member 90 to be correctly positioned relative to the locking surface 104 of the retaining member 88.

The groove 84 extends along the longitudinal length of the support member 16 and, therefore the securement apparatus 80 can be located at any position along the length thereof. The engagement portion 82 is provided on a resilient member (for example an engagement arm 86) in order for the engagement portion 82 to be movable, for example to flex down whilst being inserted into the groove and then to flex up into the recessed portion 100. The engagement arm 86 and engagement portion 82 move downwardly relative to the co-operating portion whilst being inserted into the groove and then naturally flexes upwardly to project into the recessed portion 100.

In addition, each support member 16 provides two grooves along both lateral sides and, therefore, a single support member 16 can be used to support a support surface 19 at either side thereof.

The engagement arm 86 comprises a resilient portion and preferably comprises a resilient material. The engagement arm 86 is biased towards the second (or secured) position

and, therefore the engagement portion 82 is flexed down by a wall of the opening or groove 84 whilst being inserted into the groove 84 and then flexes upwardly naturally to project into the recessed portion 100. The co-operating portion 96 acts as a guide whilst the engagement portion 82 is being inserted and, in the second position, the co- operating position abuts the lower surface of the groove 84 whilst the engagement portion 82 projects with the recessed portion in order to secure the securement apparatus 80 to the support member 16.

As shown in Figure 23, in an alternative embodiment, the support leg 12 may be arranged in a cantilever arrangement and in particular for the support legs 12 to be located towards the rear edge of the support surface 19. For example, when two desks are adjacent to each other a person working at the desk can simply and quickly move to the adjacent desk and the support legs 12 will not obstruct this movement and, in particular, a person in a chair with wheels can simply wheel themselves to the adjacent desk without moving away from the desks.

The support leg 12 comprises a lower support member 16"or lever arm 16"which is arranged to project radially away from the support leg 12 at a lower position. The lever arm 16"extends from the support leg 12 and locates underneath the support surface 19 in order to support the support surface 19. The lever arm 16"locates below the support member 16".

The lever arm 16"projects or extends away from the support leg 12 and is angled downwardly in order to abut and engage the ground at a location spaced from the

support leg 12. Accordingly, the forces acting on the support surface 19 are transferred through the support leg 12 and are transferred to the ground by the lever arm 16".

For example the foot 22 of the support leg may act as a pivot on the ground with the lever arm preventing rotation about the foot 22.

The lever arm 16"is secured to the support leg 12 by a lower retaining member 14". Accordingly, the lever arm can be arranged to project outwardly from the support leg 12 at an adjustable angle. For example, if the item of furniture is reconfigured and the size or shape of the support surface 19 is altered (and for example if the position of the upper support member 16"is changed) then the location and position of the lever arm 16"can similarly be changed. Preferably the lower retaining member 14"is spaced from the floor by a foot portion.

The lever arm 16"may comprise a substantially arcuate member. It is appreciated that all embodiments of the retaining member may be used to secure the lever arm 14" to the support leg 12.

The lever arm 16"does not require the groove or rail as previously described on the earlier embodiments of the support member 16.
