Background of the Invention During construction, and prior to the floors being permanently closed (for example by a curtain wall) temporary fencing is required adjacent the periphery of floor 1o slabs for safety purposes. Current barrier assemblies have a number of disadvantages including difficulty in providing openings for the purposes of gates, difficulty in respect of accommodating different lengths to which the barrier assemblies are to be applied, difficulty in respect of installation adjacent slab edges, difficulty in accommodating columns and other 15 protrusions, inhibiting work that is to be performed beyond the barrier assembly, such as the installations of brackets and curtain walls, with the workmen remaining on the safe side of the barrier assembly and providing suitable connection points for anchors used for safety lines and harnesses. Object of the Invention 20 It is the object of the present invention to overcome or substantially ameliorate at least one of the above disadvantages. Summary of the Invention According to a first aspect of the present invention there is disclosed herein a barrier assembly to be secured to a supporting surface, said barrier assembly including: 25 at least one upright to be fixed to the surface so as to extend upwardly therefrom; a barrier supported by the upright and including a lower barrier portion, said barrier portion being longitudinally elongated and longitudinally horizontally extending; and a kickboard assembly including a relatively rigid elongate base and a resilient 30 member extending longitudinally of said base, said base being secured to said barrier portion so as to extend longitudinally therealong. Preferably, said base has an upper and a lower longitudinally extending edge portion and said resilient member is attached to said base adjacent said lower edge portion.

2 Preferably, said base has a longitudinally extending groove, and said resilient member having a longitudinally extending projection located within the groove to secure the resilient member to the base, said groove being located adjacent said lower edge portion. 5 Preferably, wherein said base has a second longitudinally extending groove, the second groove being located adjacent said upper edge portion, and said resilient member has a second longitudinally extending portion locatable in said second groove, to selectively locate the resilient member adjacent the base. According to a second aspect of the invention there is disclosed herein a barrier 1o assembly to be secured to a supporting surface, said barrier assembly including: at least one upright to be fixed to the surface so as to extend upwardly therefrom; a barrier supported by the upright and including a lower barrier portion, said barrier portion being longitudinally elongated and longitudinally horizontally extending; an intermediate member placed on the surface so as to extend upwardly is therefrom and be secured to said barrier portion; and a kickboard assembly including a relatively rigid elongate base and a resilient member extending longitudinally of said base, said base being secured to said intermediate member so as to extend longitudinally along said barrier. Brief Description of the Drawings 20 A preferred form of the present invention will now be described by way of example with reference to the accompanying drawings wherein: Figure 1 is a schematic isometric view of a barrier assembly; Figure 2 is a further schematic isometric view of the barrier assembly of Figure 1; 25 Figure 3 is a schematic side elevation of a kickboard assembly to be used with the barrier assembly of Figure 2; Figure 4 is a schematic enlarged view of portion of the assembly of Figure 3; Figure 5 is a schematic end elevation of a kickboard base employed in the assembly of Figure 3; and 30 Figure 6 is a schematic side elevation of a frame employed in the barrier assembly as illustrated in Figures 1 and 2. Detailed Description of the Preferred Embodiment In the accompanying drawings there is schematically depicted a barrier assembly 10. The barrier assembly 10 is to be fixed to the upper surface 12 of a concrete floor slab 35 11 having an edge 13.

2a The assembly 10 includes an upright 14 which in this embodiment is a frame 15. The frame 15 has generally vertically oriented posts (uprights) 16 joined at their upper ends by a transverse brace 17 and a bottom plate 18. Typically the plate 18 would be bolted to the slab 11. 5 The posts 16 are generally parallel and the brace 17 and plate 18 are generally normal to the posts 16 and therefore also generally parallel.

3 In the present embodiment only one frame 15 is illustrated. However a plurality of frames 15 may also be employed. Supported by the frame 15 and a foot (support) 19 is a barrier 20. The barrier 20 has a longitudinal generally horizontal length 21 and includes a pair of barrier members 5 22 and 23. The members 22 and 23 are slidably coupled so that sliding relative movement therebetween adjusts the length 21. The member 23 includes a top and a bottom rail 24 and 25, each rail 24 and 25 includes a tubular member 26 to which there is attached an "angle" member 28 so that there are guide channels 27 provided within which the member 23 is slidably located. 1o In this respect it should be appreciated both members 22 and 23 are slidable through the stirrup 19, with the foot 19 being spaced from the frame 15 so as to support the barrier 20 in a raised position relative to the surface 12. The barrier member 23 has end vertical end portions 29. The member 22 has upper and lower tubular rails 30 and vertical end portions is 31. To retain the members 22 and 23 in a desired configuration providing a desired length 21, they are clamped together by means of a clamp device 32. The clamp device 32 includes a clamp bar 33 pivotally attached at its upper end to the portion 17 by means of a pivot pin 34 for angular movement about a generally horizontal axis 35 that is 20 generally parallel to the barrier 20. The axis 35 is spaced from the barrier 20 so the clamp member 33 provides a space within which the members 22 and 23 are located. The lower end of the clamp bar 33 is provided with a threaded shaft 36 having a handle 37 that is manipulated by a user. The threaded shaft 36 engages a nut 38 fixed to the post 16. Upon angular movement of the shaft 36 by manipulation of the handle 37, 25 the clamp bar 36 is moved into clamping engagement with the members 22 and 23 to clamp them, and therefore fix them, in a predetermined position relative to the frame 15. As is best seen in Figures 1 and 2, the barrier 20 is horizontally longer than it is vertically deep. The frame 15 is provided with a bracket 39 providing an aperture 40 aligned with 30 the aperture 41 of the stirrup 19. The apertures 40 and 41 receive portion of the kickboard assembly 42 so as to retain the kickboard assembly 42 generally positioned below the barrier 20. The kickboard assembly 42 includes a base 43 that would have end portions engaged in the apertures 40 and 41 so as to be supported thereby. The base 43 has longitudinally extending grooves 44. In this regard the base 43 has an upper 35 longitudinally extending portion 45 and a lower longitudinally extending portion 46, with 4 the lower groove 44 being located adjacent or at the lower portion 46. The upper groove 44 is located adjacent the upper portions 45. Releasably attached to the base 43 is a flexible member 47. The flexible member 47 has an end lip 48 with a longitudinally extending projection 49 that is received within 5 the lower groove 44 so as to attach the flexible member 47 to the base 43. As is best seen in Figure 3, the flexible member 47 has a lower sheet portion 50 joined to the lip 48, with the sheet portion 50 having a further projection 51 that is received within the upper groove 44 to aid in securing the flexible member 47 in a raised position generally abutting the base 43. 10 Preferably, the base 43 is an extruded aluminium section and is generally rigid relative to the flexible member 47. Typically the flexible member 47 would be formed of rubber, synthetic rubber or other flexible plastics material. As best seen in Figure 4, each groove 44 has entrance flanges 52 that engage the. head 53 of each projection 49. Each head 53 has steps 54 that engages the adjacent flange is 52 to aid in retaining the projection 47 in the associated slot 44. Resilient deformation of the head 49 provides for insertion and removal with respect to the associated slot 44. As best seen in Figure 6, the frame 15 includes an eyelet 55 providing an anchor point for a harness to be worn by a user. At least one of posts 16 is provided with one or more apertures 56 that are preferably of a "key hole" configuration providing for the 20 attachment of accessories such as stands and screens to the frame 15. In the above described preferred embodiment, the barrier assembly 10 has the advantage of being locatable adjacent the edge 13 while also being adjustable in length 21. Still further the flexible member 47 covers apertures extending inwardly from the edge 13, while the projection 51 is selectively locatable in the upper groove 44 to retain 25 the sheet portion in a raised position spaced from the horizontal rest portion laying on the surface 12. Use of the clamp assembly 32 enables sliding movement of the members 22 and 23 to provide openings when desired.
