Detailed Description Referring to the drawings and initially to Figs. 1 to 15 thereof there is illustrated a clamping system for modular fumiture according to the invention. The clamping system comprises a support beam 1 and a clamp for mounting to the support beam 1.

The support beam 1 is generally of light gauge metal and may for example be an extruded aluminium tube with a hollow interior 3. The beam 1 is of generally square shape in transverse cross section and has four projecting lobes 5, one at each corner. Concave portions 6 extend between each lobe 5. The clamp may comprise one, two, three or four identical clamping elements 10 for mounting to the beam 1. Each clamping element 10 has a single recess 12 of complementary shape to a lobe 5 so that the clamping element 10 can engage with and slidably move along the beam 1 by engagement of the beam lobe 5 in the clamp recess 12. Each clamping element 10 comprises a single piece having a recess 12 of complementary shape to that of the lobe 5. In use, the clamping element recess 12 fully embraces the lobe S for securely mounting the clamp to the beam 1.

The clamping element 10 fully embraces the lobe 5 so that accessories can be locked firmly to the support rail 1 without rotating, for example to hold accessories in a vertical or horizontal position relative to the support rail 1.

The support rail 1 shape is instrinsically strong to resist bending and twisting loads, thus minimising its size and wall thickness.

A entire structure such as a desk structure may be fixed to the support rail 1, therefore the complete metal structure can be pre-assembled without Worktops or screens enabling clear access for the installation of cabling and under-desk information technology equipment.

Worktops and screens can therefore be added when there is less risk of damage.

The height of the support rail 1 relative to the floor is constant, providing a consistent datum.

Screens are fixed to the support rails 1 also Worktops at variable heights: when floor standing storage or floor standing screens are added, their overall heights remain consistent with the desk- mounted screens.

Worktop sizes and fixing positions are consistent whatever the desking configuration: there is no need for multiple fixing positions therefore specification and assembly is simplified.

In the invention the beams may be orientated horizontally. In addition, the clamping action by which a single lobe is fully embraced by a groove of complementary shape in a clamping element provides a firm mounting which is resistant to twisting around the centre axis of the beam.

Each clamping element 10 also has holes 16 for fixing the clamping element to the beam lobe 5 and/or another clamping element. In this case the holes 16 are screw threaded for engagement with a fixing such as a bolt 20 extending between adjacent clamping elements. The clamping elements have threaded holes 17 for receiving fixing screws 18 which may be used to attach other elements 15 to the clamp 10. The beam 1 also has access holes 19 in the base thereof to facilitate hidden fixing/adjustment.

Clamping elements 10 are used at least in sets of two. They can perform more than one function, where positions of different accessories can be coincident, for example a pair of clamping elements 10 can fix one accessory to the support rail 1 and a third or fourth clamping element 10 can be fixed to the first or second clamping element 10 to provide a firm location. Therefore in one position along the length of the support rail 1 there could be two, three or four clamping elements 10 performing one, two, three or more functions fiom the same overall clamping assembly.

Figs. 10 to 15 illustrate the mounting of the clamping elements 10 to a beam 1. There may be a number of clamping elements(s) 10 mounted to the beam 1.

Figs. 10 to 12 illustrate a single clamping element 10 associated with a beam 1. The clamping element 10 may be mounted to a lobe 5 of the in one of two orientations (Figs. 10 and 1 1).

Fig. 13(a) and 13(b) illustrate two clamping elements 10 mounted to the beam 1. The clamping elements 10 are fixed to the beam 1 using a fixing screw 20 as illustrated. In Figs. 13(0) and 13(d) there are two clamping elements 10 which are arranged in a different configuration to provide four fixing holes 17 (two from each clamp 10) for mounting another element 15 using fixing screws 18.

Referring to Figs. 14(a) and 14(b) there is illustrated a support beam 1 with three clamping elements 10 mounted thereto. The arrangement provides an assembly to which a range of other elements can be mounted.

Figs. I5(a) and l5(b) illustrate a support beam 1 with four clamping _elements 10 mounted thereto. A wide range of other elements 15 can be readily mounted to the assembly using fixing screws 18.

The clamping elements 10 may be used to mount a wide range of accessories such as those illustrated in Figs. 16 to 20.

Fig. 16 shows an accessory holder 25 mounted to pairs of clamping elements 10 which in turn can be marked in any desired position on a support beam 1. The accessory holder 25 has grooves which provide supports for articles such as paper trays and the like.

Fig. 17 shows a power socket unit 26 mounted to pairs of clamping elements 10 which in turn can be mounted in any desired position on a support beam 1.

Fig. 18 illustrates a pair of clamping elements 10 with attachments 2 for mounting a screen therebetween.

Fig. 19 shows a pair of clamping elements 10 with a panel support 28 marked thereto.

Referring to Fig. 20 there is illustrated a pair of clamping elements 10 with an extra screen modular clamp 28, 29.

Referring to Fig. 21 there is illustrated a top support rail 30 mounted to spaced-apart pairs of clamping elements 10. The rail has depending legs 31 which can be mounted to the clamping elements in a number of different positions to adjust the height of the support rail 30 above the clamping elements as illustrated in Figs. 22 to 24. Again the clamping elements can be mounted to the support beams 1 at any desired location.

Figs. 25 to 28 illustrate an end insert 35 for a support beam 1 which may be used for example, for joining a beam 1 to an end fi'ame. The end insert 35 comprises an end frame top element 36 and an end frame bottom element 37 which are fixed together by means of grub screws 38, 39.

The insert ends 36, 37 are sized and shaped to slide into the open hollow ends of a beam 1. Each of the elements 36, 37 is formed with a raised land 40, 41 respectively which forms end stops for limiting the insertion of the insert into adjacent beams 1. Figs. 29 to 31 illustrate an assembly of the end insert 35 inserted into a beam 1 and an end frame 42. Access for grub screws 38, 39 to expand the elements 36, 37 is illustrated.

Referring now to Figs. 32 to 38 there is illustrated a post link unit 45 for use with a support beam 1 and a post 44. The link unit 45 comprises a top element 46 and a bottom element 47 which are fixed together with a grub screw 48. The top element 46 has a depending block 49 with a threaded hole 50 to receive a fixing bolt 51. A washer 52 is also used on the bolt 51. Access for adjusting the grub screw 53 is provided through the hole 19 in the beam 1.

Referring to Figs 39 to 46 there is illustrated a beam to beam link unit 50 comprising a top link element 51 and a bottom link element 52. A grub screw 53 is used to fix the link unit 50 in situ.

The link elements 51, 52 each have a section 54, 55 respectively for insertion and engagement in the open end of one beam 1 and a head part 56, 57 which embrace two lobes 5 of another beam 1. In this way an upright beam 1 can be readily jointed with a horizontal support beam 1. Thus, two adjacent support rails 1 can be joined at right angles to each other.

Referring to Figs. 47 to 55 there is illustrated a shared end frame link unit 60 which enables two support rails end to end to attach to a desk end fi°ame. The end frame can therefore be shared between two adjacent desks. The shared endframe link unit 60 comprises a top link element 61 and a bottom link element 62 which are joined together by grub screws 63, 64. In effect the link unit acts as an internal bridge between adjacent beams 1.

The various elements described above can be used to assemble a very wide range of furniture systems.

One such furniture system 70 is illustrated in Figs. 5 6 to 5 9.

Figs. 60 to 66 are views of various end frames that may be assembled using the connection system described above. The end frames may have varying length and shape.

Referring to Figs. 67 to 71 there are illustrated various worktop or tabletop support systems. The support systems comprise at least two spaced-apart support beams 1 and associated clamping elements 10. A support arm 100 extends between the support beams 1 and is mounted to the associated clamping elements 10. In the arrangement of Figs. 67 and 68 the support arm 100 is height adjustably mounted to the clamping elements 10 using mountings 101 with a plurality of mounting holes 102 through which fixing screws 103 may be engaged, depending on the desired height for a worktop 104. Some of the clamping elements 10 may have extensions 105 to define a slot 106 to receive a screen 107 which may be held in place by clamping screws 108.

The arrangement of Figs. 69 to 71 is similar to that of Figs. 67 to 68. The arrangement of Figs. 69 to 71 may be used in link tops typically of L-shape where a slide rail cannot be used.

A meeting table system is illustrated in Figs. 72 to 74 and again comprises a pair of spaced-apart support beams 1 and associated clamping elements 10. A worktop or tabletop 110 is mounted on the clamping elements 10 and is clamped in place by fixings 111 which extend through some of the clamping elements 10.

Panel supporting systems are illustrated in Figs. 75 to 77. In this case two pairs of clamping elements 10 are longitudinally spaced-apart along a beam 1 and a panel 120 is mounted to the clamping elements by fixing screws 121. There may be a spacer block 122 to provide a recess 123 for the panel 120. The panel may for example comprise a user power interface module or may have grooves which provide supports for articles such as paper trays and the like.

A cable riser track system is illustrated in Figs. 78 and 79. The cable track system comprises at least two spaced — apart support beams 1 and associated clamping elements 10. The clamping elements 10 are in this case mounted to uprights 130. The uprights 130 are spaced-apart to define a space 131 therebetween for reception of cables. The cable-receiving space is defined by an enclosure 132 which in this case has an access door or lid 133.

Referring now to Figs. 80 to 83 there is illustrated a cable track system comprising a pair of spaced-apart support beams 1 and associated clamping elements 10 and a cable track 140 mounted to the clamping elements 10. One of each pair of clamping elements 10 has a clip 141 with a downtumed and intumed lip 142 which support mesh elements 143 of the cable track 140.

The track 140 is of flexible mesh construction to facilitate ease of mounting and de-mounting of the track 140 to the clips 141 as illustrated particularly in Fig. 83.

A divider screen support system is illustrated in Figs. 84 to 85. The divider screen support system comprises a pair of spaced —— apart support beams 1 and associated clamping elements 10.

Screen receivers in the form of channel sections 151 are mounted to opposed clamping elements to receive a screen 152 therebetween. Holes 153 are provided in the channels 151 to clamp the screen 152 in a desired position. The screen 152 is raised to accommodate a worktop 155 or the like.

Referring to Figs. 86 to 88 there is illustrated an overdesk support system comprising a support beam 1 and associated clamping elements 10. An overdesk support 160 is mounted to the clamping elements 10. The support 160 may be used to mount a computer screen or TV monitor or to provide a bracket to support an overdesk shelf 165.

Figs. 89 to 91 illustrate a desk screen system in which an inner plate 170 is mounted to a clamping element 10 and an outer plate 171 is mounted to the inner plate 170, a space therebetween being controlled by a suitable spacer 172. A panel screen 174 is located between the plates 170, 171. A desktop 173 is also supported by the clamping elements 10.
