Referring to the drawings there is illustrated a modular office furniture assembly according to the invention indicated generally by the reference numeral 1. The assembly 1 comprises a number of upright ground-engaging screens 2 interconnected in a cruciform shape to define a number of work stations 3. In this case, each work station 3 is provided with a desk 4 and optionally drawers 5.

Each screen 2 comprises a rectangular framework 10 (Fig. 3) having a number of cladding panels 11, 12, 13 mounted on an exterior of the framework 10. Each framework 10 is formed by a number of vertical and horizontal frame members 14, 15 secured together by fasteners such as screws or rivets. A pair of height adjustable feet (not shown) are provided at a lower end of each framework 10.

Referring in particular to Figs. 4 to 7 the screens 2 are interconnected by connector brackets 20 and associated locking keys 19. Each connector bracket 20 is generally W-shaped and has a pair of mutually perpendicular mounting flanges 21 interconnected by a V-shaped web 22. An elongate slot 23 is provided in each flange 21 and complementary slots 24 are provided in an end wall 25 of each framework 10 (see Fig. 3). It will be noted that the slots 24 are arranged in pairs at the top and bottom of the end wall 25. The locking key 19 has a pair of spacedapart plates 28 interconnected by a narrowed neck 29. The plates 28 are sized to pass through the slots 23, 24 when aligned longitudinally with the slots 23, 24 as shown in Fig. 5 and at X in Fig. 7, to locate the neck 29 within the slots 23, 24 such that upon subsequent rotation of the key 19 the plates 28 engage outer sides of the slots 23, 24 as shown in Fig. 6 and at Y in Fig. 7 to clamp the bracket 20 to the end wall 25 of each framework 10. As can be seen in Fig. 4 the flanges 21 of each bracket 20 seats against the end wall 25 with the slots 23, 24 in alignment. The key 19 can then be inserted through the slots 23, 24 and turned to clamp the bracket 20 to the framework 10. In this way with four brackets 20 top and bottom, each framework 10 can be interconnected with the two adjacent frameworks 10. It will be appreciated that the frameworks 10 can thus be readily easily and quickly interconnected in a secure manner to define the work stations .

It will be noted that a lip 30 is provided at an outer free end of each flange 21. As can be seen in Fig. 4 each end of the framework 10 is channel-shaped with the end wall 25 defining with outwardly projecting side walls 31 a channel for reception of the flanges 21 of the connector brackets 20. The flanges 21 seat against the end wall 25 and the web 22 and lip 30 extend outwardly from the flange 21, engaging against the side walls 31 to securely position the brackets 20 in engagement with the framework 10. This fits in correctly aligning adjacent frameworks 10 and securely holds the frameworks 10 together.

Referring in particular to Figs. 8 to 11, the arrangement for mounting the cladding panels 11, 12, 13 on each framework 10 is shown. The upper cladding panels 11 and lower cladding panels 13 are mounted on support screws 40 which project outwardly of the framework 10. The screws 40 are engagable with inverted keyhole-shaped slots 41 which are recessed in a rear of the panels 11, 13. Thus, the panels 11, 13 can be readily easily and quickly mounted on the framework 10.

It will be noted that the cladding panels 12 are mounted by hinges 45 on the framework 10 and can be swung outwardly and upwardly to provide access to power points 46 and other cable connections which are routed through and housed within each screen 2.

A cable passage opening 35 is provided at a lower end of the hinged cladding panel 12. A resilient flap 36 is attached at a lower end of the hinged cladding panel 12 extending across the opening 35 to close the opening. Thus a cable can be lead from the powerpoint 46 through the opening 35 the flap 36 deflecting to allow through passage of the cable.

Flanged outer edges 50 are provided for each end wall 25 of the framework 10. Each flanged edge 50 has a number of vertically spaced-apart slots 51 for reception of associated support brackets 52 (Fig. 12) having spacedapart lugs 53 for complementary interengagement with the slots 51. The brackets 52 can conveniently be used to support the desktops 4. An alternative arrangement of desktop support bracket is shown in Fig. 14. Fig. 13 shows another Z-shaped support bracket having a hooked upper end 56 which can be mounted intermediate the ends of a screen 2 hooking over the lower cladding panel 13 and engaging one of the horizontal frame members as shown in Fig. 8. A horizontal lower flange 57 supports the desktop 4.

The invention is not limited to the embodiment hereinbefore described which may be varied in both construction and detail.
