Definitions

  • This invention relates to walkways for installation on roofs, and to a combination of such a walkway with a fall restraint system.
  • One option is to provide a physical barrier at the edge of the roof. Whilst this is relatively simple, it can be unsightly, bulky and costly to install.
  • Another option is to provide a line-based fall restraint system, such as the MANSAFE (RTM) system provided by Latchways pic of Wiltshire, United Kingdom. This requires the installation of some sort of sliding anchorage for a line for a user, and is separately purchased and installed on the roof, potentially requiring a further set of mountings on the roof to those for the walkway, hence presenting more opportunity for the integrity of the roof to be violated, with the potential for water ingress or cold bridging.
  • RTM line-based fall restraint system
  • a walkway for installation on a roof comprising a tread for a user to walk upon, the tread being bounded along an elongate side by a toe guard having an elongate extent, and an anchorage for a fall restraint system.
  • the toe guard may provide a location for the anchorage.
  • the anchorage will be a sliding anchorage, being able to slide along the extent of the toe guard.
  • a fall restraint system can be attached directly to the walkway, thus doing away with the need to provide a separate fall restraint system; only a single apparatus need be purchased and attached to a roof, with a single set of mountings.
  • the toe guard can efficiently serve two purposes, as a toe guard and as a location for the anchorage .
  • the toe guard may comprise an elongate tube coupled to the tread.
  • the tube may have a slot along the length of the toe guard, which may provide the location for the anchorage .
  • the anchorage may be received in the tube through the slot, so that a captive part of the anchorage is held captive within the tube, but typically will be able to slide within the tube along the slot.
  • the tube will be rectangular, and preferably square, in cross section.
  • the captive part of the anchorage may comprise a carriage having at least one, and preferably a plurality, typically two, wheels depending therefrom. This will enable the anchorage to traverse corners in either direction.
  • the anchorage may also comprise a mounting point for the fall restraint system; this may comprise a hitch onto which a line can be connected.
  • the tread may be substantially elongate between first and second points along a first direction, and then elongate along a second direction different to the first direction between second and third points; in such a case the toe guard may curve at the second point between running in the first and second directions.
  • the toe guard may extend around two edges of the tread, being an elongate edge along the first direction and a short edge at the transition into the second direction.
  • the anchorage may comprise a line (such as a wire or cable) running along the length of the walkway.
  • the line would be coupled to or mounted on the toe guard. The fall restraint system could then run along the line .
  • a combination comprising the walkway of the first aspect of the invention and a fall restraint system coupled to the anchorage .
  • the fall restraint system may comprise a flexible line attached to the anchorage, typically at the mounting point or hitch. This line would typically be coupled to a user, potentially via a lanyard.
  • the fall restraint system may also comprise a fall arrest system, which is arranged to gradually dissipate the kinetic energy of a falling user.
  • the walkway of the first aspect of the invention installed on a roof.
  • the walkway may form part of the combination of the second aspect of the invention.
  • Figure 1 shows a transverse cross section through a walkway in accordance with an embodiment of the invention
  • Figure 2 shows a plan view of the walkway of Figure 1 ;
  • Figure 3 shows a longitudinal cross section through the walkway of Figure 1 ;
  • Figure 4 shows a side elevation of the sliding anchorage of the walkway of Figure 1 ; and Figure 5 shows an end elevation of the sliding anchorage of Figure 4.
  • the accompanying drawings show a walkway 1 that can be installed on a roof, where it is desired to reduce the likelihood of a user of the walkway falling and injuring themselves.
  • the walkway 1 comprises a tread 2, which comprises a plurality of metal (typically extruded aluminium) slats 3 held between a pair of toe guards 4, 5, again typically formed of extruded aluminium.
  • the toe guards 4, 5 run along each lateral edge along the length 6 of the walkway and each engage the slats through a socket portion 9, 10. They each provide an upstanding portion 7, 8 at the edge of the tread 2, which provides an edge to alert a user that they are approaching the edge of the walkway 1.
  • the upstanding portion 7 is provided by a tubular box section 1 1.
  • This has a slot 12 therein, extending along the length 6.
  • a sliding anchorage 13 is provided that is held captive within the box section 1 1 , so that a carriage portion 14 is received within the tube, but a mounting portion 15 extends out of the slot.
  • a flexible line (not shown) can then be attached to the mounting portion 15 (of the form of a hitch or bolt or similar) in order to be attached to the user as a fall restraint or fall arrest system.
  • the carriage portion 14 is U-shaped as shown in Figure 4 of the accompanying drawings and carries four wheels 16; two above the slot 12 and two below, with a pair of wheels 16 on each arm of the U-shape.
  • the sliding anchorage 12 can slide along the length 6 of the first toe guard 4 as a user walks to and fro along the walkway 1.
  • the location of the sliding anchorage is provided within the first toe guard 4, thus providing an integrally formed walkway and fall restraint system whilst making efficient use of the first toe guard 4.
  • less material is used and fewer products need to be bought in order to provide a safe walkway on a roof. Only the mountings required to mount the walkway to the roof are required; there is no need for a separate set of mountings for the fall restraint system.
  • the first toe guard 4 can extend around a front side 20 of the walkway 1 at right angles to the length 6.
