The platform support apparatus 2 comprises platform support means 3, a post support member 4, angle adjusting means 5, height adjusting means 6, surface support means 7, and frame fixing means 8. The apparatus 2 is constructed from steel components.
The platform support means 3 comprises a platform support member 10, formed of rectangular hollow section steel, and a clamping bar 12 connected near each of its COMS ID No: ARCS-210766 Received by IP Australia: Time 23:38 Date 2008-10-22 22/10 2008 22:34 +61 3 9543 8822 Morcom Pernat Morcni Prnat#0230 P.014/030 009 0 ends to the platform support member 10 by a pair of bolts 14 which are threadedly engaged through respective long nuts 16 welded within the platform support member 0 10. As shown in Figure 3, three side by side planks 86 form a platform 87 which is supported on the platform support member 10 and beneath the clamping arm 12.
The post support member 4 comprises a length of square tube 20 which projects upward from one end of the platform support member 10, and is rigidly welded to the 0 support member 10 via a clevis 18. As shown in phantom lines on Figure 3, a square 0 tubular safety post 104 may be mounted on the platform support member by sliding it 00 10 over the upright square tube 20 of the post support member 4. The safety post 104 0 supports horizontal safety rails 106 which extend across to another safety post mounted on a second platform support apparatus which is laterally spaced from the platform support apparatus 2 shown.
The angle adjusting arm 5 comprises first and second telescopic parts 24 and 26 respectively formed of square hollow section steel having a loose sliding fit therebetween. The first telescopic part 24 carries a series of spaced apart circular holes 28. The second telescopic part 26 also carries a series of spaced apart circular holes 30, although the centre to centre spacing 31 (see Figure 7) between adjacent holes 30 is only about 86% of the spacing 33 (see Figure 7) between adjacent holes 28. The holes 28 and 30 have the same diameter and the shaft of the D-pin 35 forms a loose fit therethrougli for locking the first and second parts 24, 26 together at the desired overall length of the arm The height adjusting means 6 comprises a height adjusting arm 32 and a sliding bracket 34. The bracket 34 is securely welded to one end of the platform support member 10. The sliding bracket 34 includes a bolt 36 which interconnects a pair of parallel flanges 37 and 39 of the bracket 34. The flanges 37 and 39 extend on respective sides of the height adjusting arm 32. The flanges 37 and 39 each carry a notch 38 (shown more clearly in Figure 7) adapted to receive the shaft of a D-pin and a circular hole 42 which is also adapted to receive a D-pin 44. The notch 38 may be aligned with any of a series of apertures 46 present along the height adjusting arm COMS ID No: ARCS-210766 Received by IP Australia: Time 23:38 Date 2008-10-22 22/10 2008 22:35 ±61 3 9543 8822 Morcom Pernat #0230 P.015/030 00 32. The top of the height adjusting ann 32 is pivotally attached at 48 to the top of the first telescopic part 24 of the angle adjusting arm The surface support means 7 comprises a pair of laterally extending feet 49 and interconnected by a telescopically adjustable intermediate member 52. The intermediate member 52 has an outer sleeve portion 51 within which slides an inner sliding portion 53. An L-handle locking screw 54 extends through the upper wall of 0 the outer sleeve portion 51 to clamp against the inner sliding portion 53 and thereby lock the intermediate member 52 at the desired length. First and second rising struts, 00 10 60 and 62 respectively, are welded to and extend upward from the outside end of the 0 outer sleeve portion 51, and are joined at their top ends by a spacing strut 64. Each foot 49, 50 has a layer of sheet rubber 70 present on its under surface to act as a cushion and assist grip.
The frame fixing means 8 is a clamping assembly. It comprises a first square tubular member 72 having a support holding member 74 welded thereto. The clamping assembly 8 has a second square tubular member 76 which slides telescopically within the first square tubular member 72, a clamping arm 78 which projects from the base of the second square tubular member 76, and a threaded shaft 80 which passes longitudinally through tubular members 76 and 72 and extends from both ends thereof. The shaft 80 passes out through an aperture in the top of the first square tubular member 72, where the shaft carries an enlarged head 82 which is too wide to fit down through the aperture in the top of the first square tubular member 72. The shaft 80 is threadedly engaged with a nut 1 10 which is welded to the base of the second square tubular member adjacent the clamping member 78.
Referring to Figure 3, the platform support apparatus 2 is shown in use on a pitched roof comprising roof tiles 108 laid on timber battens 100 which are fastened across underlying rafters 102.
The distance between the feet 49, 50 can be adjusted by telescopically lengthening or shortening (as indicated by arrow 94) the intermediate member 52. Rotation of locking member 54 in an anti-clockwise direction causes unlocking, allowing COMS ID No: ARCS-210766 Received by IP Australia: Time 23:38 Date 2008-10-22 22/10 2008 22:35 61 3 9543 8822 Morcom Pernat Marcni Prnat#0230 P.016/030 0 telescopic adjustmnent of the intermediate member 52. To lock the length of the intermediate member 52 and therefore the distance between the feet 50, the locking C) member 54 is rotated in a clockwise direction. The clamp assembly 8 is used to Ni retain the platform support apparatus 2 in position on the root, In order to attach the apparatus 2 to the roof, the length of the intermediate member is first adjusted so that the feet 49, 50 are spaced to be at least close to the centre to centre distance between a suitable pair of battens 100a, 100d. As seen in Figure 3, there are two flurther battens 10O0b, 100~c between those battens underlying the feet.
00 The middle tile 108a is displaced upwards so it rests beneath the uphill tile ]O8b 0 underlying uphill foot 49. This creates an opening 107 between the middle tile 108a and the downhill tile 108ce underlying the downhill foot The support holding member 74 of the clamp assembly 8 has a flat main clamping is face 114 and a downwardly depending lip 116 along that edge of the member 74 opposite the tubular member 72, so the member 74 has the form of an upside-down channel, As indicated by the arrow 96 in Figure 1, the member 74 is placed over the intermediate member 52 so the face 114 bears down on the outer sleeve portion 51, the lip 116 overhangs the side of the outer sleeve portion 51, and the second square tubular member 76 extends down through the opening 107 as seen in Figure 3. The head 82 of the shaft 80 is rotated to lower the clamping arm 78 until it is able to slip under the batten 100c which is immediately downslope of the opening 107. The clamping arm 78 is slid beneath the batten 100c and the head 82 rotated to tighten the clamping arm 78 up against the underside of the batten 100c, thereby clamping the platform support apparatus 2 to the roof.
In order to mount the platform 87 on to the apparatus 2, the bolts 14 are screwed upwards and the clamping arm 12 is raised (as indicated by upward arrow 84). An end of the plank 86 or planks is/are positioned between the clamping arm 12 and the platform support member 10 (as indicated by arrows 88). One end of each plank 86 is supported by the platform support member 10 shown whilst the other end of each plank 86 may be supported by a platform support member of an identical second platform support apparatus which is laterally spaced from the platform support COMS ID No: ARCS-210766 Received by IP Australia: Time 23:38 Date 2008-10-22 22/10 2008 22:35 ±61 3 9543 8822 Marconi Pernat #0230 P.017/030 00 12 apparatus 2 shown, where respective the feet 49, 50 of both platform support ci apparatuses are substantially in line. The clamping arm 12 is lowered (as indicated 0 by downward arrow 84) on to the top surface of the planks 86 and the bolts 14 are screwed down so that the planks 86 forming the platform 87 are secured on to the platform support member Figure 4 shows an atrtieconfiguration for the clamp assembly 8 which forms a 0 frame fixing means wherein the clamping arm 78 projects out on the same side of the 0 square tubular members 72, 76 as does the support holding member 74. This 00 10 orientation enables the clamping arm 78 to be clamped to a rafter 102 as shown in O Figure 5. This is more secure than clamping to a batten as in Figure 3 because the batten may not be securely affixed to the rafter. The same clamp assembly 8 may be swapped between the configurations in Figures 1 and 4 by unscrewing the shaft completely from the nut 110, separating the tubular members 72 and 76, and reassembling them in the desired orientation.
A pair of flanges 83 project from the first square tubular member 72 on the clamp assembly 8. As shown in Figure 5, the flanges are used for weather-proofing the roof beneath the apparatus. A panel of flexible plastic sheet 112 is used to cover the opening 107 between the tiles in order to prevent rainwater from leaking into the roof through the opening 107. The uphill portion of -the sheet 112 is held between the uphill tiles 108a and 108b, and the downhill portion of the sheet 112 is held between the downhill foot 50 and downhill tile l08e. The two parallel flanges 83 are provided on the first square tubular member 72 so that the plastic sheet may be tucked into the channel 85 between the flanges at a level which raises the perforated centre of the sheet 112 slightly above the surrounding portions of sheet in order to prevent leakage.
Optionally a short length of string (not shown) may be wound into and tied into the channel 85 to secure the sheet 112 to the clamp assembly

The angle of the platform support member 10 may be adjusted to the horizontal position so that the platform is horizontally aligned across the planks. To raise the angle of the platform support member 10 toward horizontal, the D-pin 3 5 through the angle adjusting arm 5 must first be removed. The first telescopic part 24 is slid down COMS ID No: ARCS-210766 Received by IP Australia: Time 23:38 Date 2008-10-22 22/10 2008 22:36 ±61 3 9543 8822 Morcom Pernat Morcm Penat#0230 P.018/030 00 13 o (as indicated by downwards arrow 90) around the second telescopic part 26 thereby shortening the angle adjusting arm. Once a substantially horizontal alignment of the o platform support arm 10 is reached, the shaft of the D-pin 35 is passed through whatever pair of apertures 28, 30 in the first and second telescopic parts 24, 26 is aligned, thereby locking the angle adjusting arm so that the platform support member remains substantially horizontal.
Conversely, to lower the angle of the platform support member 10 toward horizontal, the first telescopic part 24 is slid up (as indicated by upwards arrow 90) around the 00 i0 second telescopic part 26 thereby lengthening the angle adjusting arm. Again, once a suitably horizontal position of the platforms support arm 10 is reached, the D-pin is inserted into a pair of aligned apertures 28, 30 thereby fixing the length of the angle adjusting arm so that the platform support member 10 is held substantially horizontal.
As the two arrays of holes 28, 30 have different centre to centre spacings, only about every seventh set of four holes is in alignment at any one time. This allows very fine adjustment of the length of arm 5, and thus the angle of the platform support member which can be set at about 1P increments.
Either before or after the horizontal aligning of the support member 10, the support member 10 can be vertically adjusted to the desired height by raising or lowering (as indicated by arrows 92). D-pins 40, 44 are first removed to enable the sliding of bracket 34 up or down the height adjusting arm 32. The bracket 34 slides on bolt 36 'along the height adjusting arm 32. The bolt 36 remains through the bracket 34 to keep the bracket captive on the arm 32. The bracket is slid to a position such that the notch 38 is located just above a desired aperture 46 in the height adjusting armn 32.
The D-pin 40 is passed through the desired aperture and the bracket 34 is lowered so that the notch 38 fits down around the D-pin 40, thereby preventing the platform support member 10 from being lowered any further. Another D-pin 44 is then passed through the aperture 42 in the lower part of the bracket 34 in order to prevent upward tilting of the bracket 34. The downwards load from the platform is taken entirely by the D-pin 44 as the bolt 36 and D-pin 44 do not pass through the arm 32.

So the apparatus 2 is instead preferably screwed to the roof. This may ci be done without creating any perforations in the steel sheeting further to those required for conventional attachment of the sheet to the roof.
Mn In Figure 6, the platform support apparatus 2 is shown in use on a pitched roof 0) comprising a corrugated steel sheets 98 supported on roof battens 100 which are affixed underlying rafters 102. The length of the intermediate member 52 is adjusted o0 10 so that each foot 50 overlies. a batten 100. The feet 49, 50 are spaced to overly 0 respective battens 100 and the screw 54 is tightened slightly so as to allow some forced sliding between portions 51 and 53. At the position on the roof desired a few screws holding the corrugated steel down are removed and the feet 49, 50 placed over the holes so revealed. The base of each foot 49, 50 carries a plurality of slots 56 adapted to receive screws 58 therethiough. The feet 49 and 50 are then fastened to the battens 100 by screws 58, which are fed through the slots 56 and the existing holes in the corrugated steel and into the battens, thereby fixing the platform support apparatus 2 in position on the pitched roof. The rubber sheet cushions 70 prevent or reduce any damage to the upper surface of the sheet steel which may be painted.
The clamp assembly 8 is not needed in this embodiment of the invention.
Figure 7 shows the platform support apparatus 2 in a collapsed position suitable for transport and storage. In order to collapse the apparatus 2, D-pins 35, 40, and 44 are removed. The sliding bracket 34 is lowered down the height adjusting ann 32, and the angle adjusting arm 5 is lengthened causing the height adjusting ann 32 to pivot at 68 down towards a horizontal position.
