  • the assembly of this embodiment comprises a combination of various components from which a safety guardrail fence can be constructed. It is the intention of the invention to provide an assembly for constructing a safety guardrail fence around a periphery of a roof surface of a building to provide a means of preventing persons working on the roof from falling therefrom.
  • the assembly in accordance with the first preferred embodiment comprises posts 10, rails 12 and at least one support device 14.
  • the posts 10 are of generally serpentine form in a lengthwise direction, i.e. generally "S"-shaped.
  • each post 10 comprises lower middle and upper portions (10a, 10b, 10c) which are each inclined with respect to an adjacent portion.
  • a lower portion 10a of a post 10 locates within a socket member 16 of a support device 14 such that said post 10 can be located on a roof surface 18 adjacent a parapet 20 thereof and supported to be extending generally upwardly therefrom.
  • the support device 14 comprises an elongate planar base member 22 with the socket member 16 located adjacent one end thereof extending upwardly therefrom.
  • the socket member 16 is inclined with respect to the base member 22 such that it leans slightly towards the end of the base member 22 farthest from its point of attachment to said base member 22 and makes an angle of slightly less than 90° with the base member 22. Consequently, the posts 10 are supported by support devices 14 with their lower portions 10a inclined with respect to the base member 22 and thus the roof surface 18 at a similar angle of inclination.
  • each post On the middle and upper portions (10b, 10c) of each post are located collars 24 which, in use, enable rails 12 to be supported between adjacent posts 10 in a conventional manner, as is better illustrated in figure 3.
  • the form of the posts 10 is such that, when in a first position (as shown in figure 2) , rails 12 supported between the posts 10 are generally positioned on a support means side of the posts 10, i.e. on an inner side of the posts relative to the roof parapet 20.
  • the fence so constructed can be generally inclined inwardly from the parapet 20 in a conventional manner thus providing the same level of protection afforded by the known systems.
  • the form of the posts 10 and the arrangement of the rail support collars 24 thereon is such that said posts can be rotated from their first conventional positions through 180° about their longitudinal axis to occupy second positions supported by the support devices 14.
  • Figure 4 illustrates this and shows that, in this case, an axis passing through the centre of the support cellars 24 and thus, in use, the centre of supported rails 12 makes ar. angle of 90° with the base member 22 cf a supper" device 14.
  • the rails 12 are then supported ir. positions on an outer side of the posts 10 relative co the roof surface 18.
  • the assembly of the first preferred embodiment can, without requiring any additional components, allow a guardrail fence to be constructed in which, in one case, the fence inclines inwardly from the roof periphery or, in another case, the fence is generally perpendicular to the roof surface 18, assuming, of course, that the roof surface is itself horizontal.
  • the guardrail fence still provides the degree of safety required of such a fence.
  • FIG 5 A further distinct advantage of the present invention is better illustrated by figure 5 in which it can be seen that a guardrail fence has been constructed on an inclined portion 18a of a roof surface 18.
  • the posts 10 can be placed in their second positions relative to the support devices 14 to counter the angle of inward incline of the sloping roof portion 18a thus still providing an effective guardrail fence. It will be appreciated that the safety of the guardrail fences of the known systems having an inclined form would be compromised by a further inward incline due to their being constructed on an inwardly inclined sloping roof portion since their vertical height would be reduced.
  • the dimensions of the posts 10 of the first preferred embodiment are such that, with the rail support collars 24 arranged on the middle and upper portions (10b, 10c) of said posts 10, supported rails 12 are spaced outwardly from the lower portion 10a of the posts 10 by a distance greater than the diameter of a rail.
  • the distance A illustrating this is approximately one and a half times the diameter of a rail 12 and this has been found to provide the degree of incline required for a fence of conventional height when the posts 10 are arranged in their respective first positions and yet allow a fence which has rails 12 supported generally one above each other in a plane perpendicular to the support surface when the posts 10 are arranged in their respective second positions.
  • Figure 6 shows a subassembly of an assembly according to a second embodiment of the invention.
  • This comprises, in addition to a support device 30 and posts 10 shown in the figure 1, rails (not shown) to be supported between adjacent posts 10.
  • the support device 30 is of a different form to that of the first embodiment and comprises an arcuate support member 32 having at a first end an anchor block 34 which rests upon the roof surface 18. A second end of the support member 32 engages a post 10 to support it in a generally upright position.
  • the posts 10 are also of serpentine form although they are arranged such that, when supported on the rocf surface 16, the lower portions 10a thereof are normal to said surface 18.
  • the posts 10 can occupy first positions as shown in the figure and can be rotated through 180° to occupy second positions (not shown) .
  • the rail support collars 24 are arranged on only the upper portions 10c of the posts 10.
  • the upper portions 10c are longer than the corresponding portions of the posts 10 of the first embodiment.
  • the figure shows the subassembly in its normal arrangement on a horizontal building roof surface but it will be appreciated that, on an inwardly sloping roof surface 18 the posts 10 can be arranged in their second positions to provide an inwardly inclined guardrail fence without the addition of further components to the assembly.
  • Figure 7 shows a side elevational view of a subassembly for an assembly according to a third embodiment of the present invention which, in addition to the posts 40 and support devices 14 shown in the figure, comprises rails (now shown) .
  • the support devices 14 are of similar form to those of the first embodiment although the sockets 16 of the support devices 14 are preferably at right angles to the base members 22.
  • the posts 40 are of a different form comprising straight posts with spars 42 extending outwardly therefrom and having rail support collars 24 at their outer ends. As shown in the figure, the posts 40 are in their first positions relative to the support devices 14 and a guardrail fence constructed therefrom would have a conventional form.
  • guardrail fence can be constructed in which the rails are supported outwardly of the roof to provide more room for workers on the roof .
  • an assembly according to the invention may comprise any combination of the various components of described embodiments.
  • an assembly might comprise the posts of the third embodiment with the support devices of the second embodiment together with rails.
