  • an external feature 330 is also able to be fitted to the installed external facade 320.
  • the hoist 230 When it becomes necessary for the perimeter safety screen assembly 1 to be raised up the side of the building, the hoist 230 would be connected to the folding section 212 via the cable 231 and the folding section 212 would be moved to its open position (as shown in Figures 4 and 9) enabling the hinged platform 210 and the hanging screen assembly 200 to which it depends to be lifted past the completed external feature 330 and exterior facade 320. Once the hinged platform 210 has passed the external feature 330 it is able to be lowered to its closed position.

  • FIG. 411 Rotatably depending from a distal end of the bracket 411 is an inner platform 420 atop a folding section 421 adapted to move between a closed position and an open position ft can be seen that this folding section 421 has a first distal end 422 and a second proximal end 423, and that the folding section 421 is rotatably attached to the distal end of the bracket 414 at a position intermediate its first and second ends 422, 423.
  • the folding section 421 When in the closed position, the folding section 421 is rotated such that the inner platform 420 is substantially horizontal and parallel with the outer platform 410, and the proximal end 423 of the folding section 421 bears against the underside of the horizontal arm 412 of the bracket 411 so as to support the folding section 421 in this position.
  • the folding section 421 When in the open position, the folding section 421 is rotated up such that the inner platform 420 is substantially vertical and perpendicular to the outer platform 410, the distal end 422 of the folding section 421 extending upward, above the outer platform 410, and the proximal end 423 of the folding section 421 extending downward, below the outer platform 410.

  • the hinged platform 400 further comprises an intermediate flap section 440 pivotally attached to a distal end of the outer platform 410 and configured to bear against the upper surface of the inner platform 420. It will be appreciated that when the folding section 421 is in the closed position, the intermediate flap section 440 lies across a gap formed between the inner and outer platforms 420, 410, and as the folding section 421 is moved to the fully open position, it can be seen that the intermediate flap section 440 pivots upwardly while continuing to bear against the inner platform 420, through to the fully open position where the intermediate flap section 440 lies against the inner platform 420.
  • the hanging screen assemblies only comprise a single hinged platform, it will be appreciated that in alternate embodiments, the hanging screen assembly may comprise multiple hinged platforms or a combination of fixed and hinged platforms. For instance, in an alternate embodiment, a hanging screen assembly may comprise two platforms, where the uppermost platform is fixed and the lowermost platform is hinged.
  • a single embodiment may, for succinctness and/or to assist in understanding the scope of the disclosure, combine multiple features. It is to be understood that in such a case, these multiple features may be provided separately (in separate embodiments), or in any other suitable combination. Alternatively, where separate features are described in separate embodiments, these separate features may be combined into a single embodiment unless otherwise stated or implied. This also applies to the claims which can be recombined in any combination. That is a claim may be amended to include a feature defined in any other claim. Further a phrase referring to “at least one of’ a list of items refers to any combination of those items, including single members. As an example, “at least one of: a, b, or c” is intended to cover: a, b, c, a-b, a-c, b-c, and a-b-c.
