Definitions

  • the invention relates to a roofing seat device suitable for mounting to two roof battens for lateral movement along the battens.
  • Roof construction generally involves affixing rafters to a base (building shell) to define an inverted V-shape structure above the base.
  • the rafters are covered with felt or other waterproof material.
  • Across the felt are affixed a series of cross battens perpendicular to the rafters.
  • the battens are generally parallel to the top edge of the inverted V-shape structure.
  • a series of overlapping slates are laid or fixed to the battens.
  • Slating roofs can be a difficult task for workers as they are someway from the ground and need to feel secure as they work. Particularly, a worker or user in such a situation will be required to frequently move his or her position, so as to collect slates, lay the slates on wooden battens and move onto the next portion of the roof that he or she is working on.
  • one roof may be at an angle of 45 degrees to the vertical, whereas a second roof may be at an angle of 20 degrees to the vertical.
  • United Kingdom patent application GB 2229482 discloses a roofing seat device capable of engaging with roof battens for rolling movement across a slanted roof during construction or slating of the roof, the device comprising a support base having first batten engagement means, second batten engagement means, and a seat disposed at an angle with respect to the support base for supporting a person during use, wherein the first and second batten engagement means comprise rollers adapted to roll along a batten, and wherein the spacing between the first and second batten engagement means can be adjusted.
  • both of the batten engagement means are adjustable with respect to the support, thereby allowing adjustment of the device to fit to roofs with battens having different spacing and to allow the seat maintain a horizontal disposition on roofs of different pitches.
  • Fig. 1 it will be seen that when a person is located on the seat of the device, most of the weight will be loaded axially onto the length adjustable bar which causes wear and tear, and ultimately breakage, of the adjustment mechanism of the adjustable bar. Further, adjustment of the device to enable it to be mounted on roofs having different pitches requires adjustment of the batten engagement means, even if the batten spacing on the roofs is the same.
  • EP 0042465 and German Utility Model No. 8705770 both disclose a carriage suitable for engagement with and rolling movement along two roof battens or roof mounted.
  • the carriages disclosed in both applications are not adjustable so that they cannot be used on roofs with battens having different spacing.
  • the support surface is unsuitable for use as a seat for a person.
  • US Patent Publication No. 2008/0309033 discloses a seat for a person on a roof that can only be applied on the roof ridge and not on inclined roof sides.
  • a roofing seat device capable of engaging with roof battens for rolling movement across a slanted roof during construction or slating of the roof, the device comprising a support base having first batten engagement means, second batten engagement means, and a surface for supporting a person during use, wherein the first and second batten engagement means comprise rollers adapted to roll along a batten/rail, wherein the first and second batten/rail engagement means comprise rollers adapted to roll along a batten/rail, wherein the first batten/rail engagement means comprises two spaced apart pairs of rollers each pair comprising a first roller which is adapted to engage a top of a first batten/rail and a second roller which is adapted to engage an upper side of the first batten/rail, and the second batten engagement means comprises two spaced apart rollers each roller adapted to engage a top of a second batten/rail; characterised in that the surface for supporting the person is a seat which is adapted for adjustment of the angle of the seat with respect
