  • the gutter system 10 comprises a plurality of gutter tiles 20, a gutter 22 and a water collection system in the form of a plurality ofa plurality of conventional roof tiles 24
  • the tiles 20 and 24 are supported upon rafters 26 and the underside ofthe rafters 26 are closed off from the elements by roof eaves panels 28
  • the rafters 26 also support a facia 30 which in turn supports the butter 22
  • the gutter tiles 20 are arranged in much the same manner as the conventional tiles 24 except that they lie over the gutter 22 to close off the gutter 22 This is in complete contrast to what is accepted as how roof sheeting should be laid in relation to a gutter 22
  • each of the gutter tiles 20 has an upper surface 40, a lower surface 42, an upstream end 44 and a downstream end 46
  • the gutter tile 22 is formed with a conventional tile section 48 which extends from the upstream end 44 to intermediate the length of the tile 20, and a modified tile section 50 which extends from the downstream end 46 to intermediate the length of the tile 20
  • the purpose of the conventional tile section 48 is to enable the tile 20 to fit into the conventional tile 24 in the normal way, and the purpose of the modified tile section is to more efficiently control the flow of water into the gutter 22 whilst inhibiting the passage of debris into the gutter 22
  • the conventional tile section 48 has a central ridge 52 which in intended to split the flow of water down the tile 20 into two halves
  • the conventional tile section 48 has a profile which allows the tile 20 to couple with the conventional tile 24 at its upstream end 44 and to couple with further gutter tiles 20 at its sides
  • the modified tile section 50 has a water control surface 60, a plurality of holes 62, a pressurisatio ⁇ slot 64, a facia sealing surface 66 and a fastening lug 68
  • the water control surface 60 typically has gullies 70 arranged in a criss-cross pattern and having an appearance similar to a bar of chocolate
  • the gullies 70 are interposed with bumps 72
  • the holes 62 are located in the gullies 70 in the downstream end of the water control surface 60 and are arranged above the gutter 22
  • the holes 62 allow the flow of water from the water collection surface 60 into the gutter 22
  • the holes 62 have a profile which includes a curved upper lip 80 located in the upper surface 40 of the tile 20
  • the curved upper lip 80 leads to an inlet cone 82, which terminates at a cusp 84, which leads into a fluted siphon tube 86, which has its outlet at a discharge end 88 located in the lower surface 42 of the tile 20
  • the inlet cone 82 typically has an angle of greater than about 40o to the horizontal
  • the fluted siphon tube 86 flares from the cusp 84 to the discharge end 88 by an angle of 2o to 3o typically If the angle is smaller than this the siphon effect is inhibited and if the angle is much larger than this the siphon effect does not occur Also, to assist in achieving the siphon effect the tube 86 must be longer than it is wide and more particularly that its length be about twice its width
  • the holes 62 are offset in the gullies 70 This has the effect of causing th water to spiral into the holes 62 as indicated by arrows 90
  • the size of the arrows 90 indicates the speed and energy of the water as it flows into the holes 62
  • water that does not flow into an upstream one ofthe holes 62 tends to flow into one ofthe downstream ones of the holes 62
  • the pressunsation slot 64 is located in the downstream end 46 of the tile 20 and sits over the edge ofthe gutter 22 so as to form an aperture for air to flow into a gutter chamber 92 formed by the gutter tile 20 and the gutter 22 (see Figures 1 and 7)
  • the pressurisation slot 64 allows air to flow into the gutter chamber 92 to pressurise the gutter chamber 92 and flow upwardly out ofthe holes 62 in the direction of arrows 94 It is this upward flow of air through the holes 62 which assists in inhibiting the lodging of debris in the holes 62
  • the facia sealing surface 66 seals the lower surface 42 of the tile 20 to the gutter 22 so as to seal off the gutter chamber 92 to ensure that the flow of air goes through the holes 62 instead of leaking into the roof cavity 96
  • the fastening lug 68 is located proximate the downstream end 46 and sits over the gutter 22
  • the fastening lug 68 receives a clip 98 which is pivotably attached to the gutter 22 at one end and which sp ⁇ ng clips on to the fastening lug 68
  • the fastening lug thus positively attaches the tile 20 to the front edge ofthe gutter 22 This has the effect of maintaining the definition ofthe pressurisation slot 64 and hence ensuring the gutter chamber 90 will be pressurised by the flow of air in the vicinity of the gutter 22
  • the gutter system 10 in accordance with another aspect of the present invention has an adjustable height gutter 99 comprising a plurality of brackets 100, a facia 102 and a plurality of clips 104 for fixing the gutter 20 to the rafters 26.
  • the brackets 100 typically have ganged nails formed in them for fixing to the rafters 26.
  • the facia 102 is shaped to sit upon the brackets 100 and so be attached to the rafters 26
  • the facia has a plurality of horizontally disposed ridges 110 located proximate its upper end.
  • the gutter 22 also has a plurality of horizontally disposed ridges 112 arranged to mate with the ridges 1 10 of the facia.
  • the ridges 110 and 112 are arranged so as to provide a ratchet effect as the gutter 22 is pushed upwardly. In this way the height ofthe gutter 22 with respect to the facia 102 can be adjusted. This is necessary where the pitch of the roof varies such as shown in Figures 10.4 (14o pitch) and 10.5 (45o pitch). Then once the gutter tiles 20 are laid the front ofthe gutter 20 is supported by the connection to the tiles 20 with the clips 98. That is, the ridges 110 and 112 on the facia 102 and the gutter 22 allow easy adjustment ofthe height ofthe gutter 22 for rooves of differing pitch.
  • the tile could be a metal tile 120 for use with metal roof sheeting 122.
  • the tile 120 is similar to the tile 20 and like numerals denote like parts.
  • the only real difference between the tile 120 and tile 20 is that the tile 120 has a corrugated profile so as to match the profile of the roof sheeting 122. It is to be understood, however, that the tile 120 could have other profiles to match roof sheeting 122 of differing profiles.
  • the system is a method of efficiently separating water and litter or debris.
  • the cover is designed with to cope with the maximum likely water flow and provide the maximum flat area to obstruct litter.
  • the typical pipe has a cross-sectional area of around 50 sq cm. receiving the water from about 14 metres of gutter (50 sq. metres of roof)
  • the inlet area is around 15,000 sq. cm., or 300 times bigger than the area of the down-pipe outlet.
  • the house gutter inlet area is clearly many times greater than necessary to collect the water.
  • the inlet hole 62 area on 14 metres of Sadleir system gutter tiles is about 400 sq. cm., or 8 times the cross-sectional area of the down-pipe. This still leaves around 97% of the cover surface available to prevent debris such as falling leaves from lodging in the gutter. The debris is blown away in the wind or simply slides off the roof.
  • the Sadleir system allows around 3 to 5 times the gutter 22 capacity. This additional capacity is designed to cope with the variations in down-pipe capacity, roof slope, varying length of collection surface and occasional temporary blocking of holes 62.
  • the separation of storm water and road litter requires some variation to the system used on roof gutters.
  • the road gutters are generally exposed to the wind resulting in better drying of litter and greater movement. Additionally, gutters are generally cleaned on a regular basis by road sweepers Water takes longer to reach the pipe system on the roads compared to the roof situation Road slopes are generally less than that on the roof and the water has further to travel
  • roof litter is in the form of twigs, leaves or needles
  • Leaves are generally flat with length and width greater than about 10 mm
  • the holes 62 on the Sadleir system are about 7 mm in diameter and the inlet cone 82 is about 20 mm in diameter
  • Pine needles and twigs are similar in shape and character Both can have very small diameters, down to about 2 mm and are generally greater than 50 mm in length They often have hooks protruding from part of the stem When they fall on to a roof or road, they tend to stay flat Providing the surface is relatively smooth and no wind-protected gullies exceed about 20 mm in width and length, the twigs and needles are blown freely around and off the roof or down the road This is the case with the Sadleir gutter system
  • the Sadleir gutter system 10 uses a substantially smooth flat surface 40 which can be streamlined by minimising wind obstructions from tiles 20, 24, gutter 22, or curbing SLOPING UPPER SURFACE
  • the cover In order for gravity to assist the cleaning process, the cover needs some level of slope. The greater the slope, the easier it is for material to slide off the roof. Tests indicate the Sadleir gutter system 10 can cope with up to 40 degrees in slope without effecting the water control surfaces 60
  • Water coming off a roof can travel in the form ofa fast flowing, narrow and erratic stream.
  • This water In order for this water to enter a number of scattered drainage holes 62 whose axis is at right-angles to the flow, it needs to be slowed, controlled and guided into the holes.
  • the speed of water flowing down a roof gully or roadway gutter can often exceed 100 cm sec. At this speed, a horizontal water stream initially arcs down with an average radius of about 4 cm. For the stream to flow into a pipe, an inlet cone of around 10 cm in diameter would be required. This size hole 62 would not effectively filter many types of debris. Slowing the water can be done by a number of methods including, the bumps 72 and the gullies 70.
  • the size of the bumps 72 or gullies 70 need to be large enough to provide sufficient turbulence in the water in order to absorb the kinetic energy in the water and thereby slow the flow.
  • the bumps 72 or gullies 70 work well when the width of the bumps 72 is similar to the inlet cone 82 diameter (20 mm) wide, the height of the bumps 72 is similar to the hole 62 diameter (7 mm) and the gap between the bumps 72 has similar area to the filter hole 62 area (0 3 sq.cm ).
  • These devices are designed to slow the water to a speed which allows it to fall naturally into the filter hole 62.
  • the slowed water stream in these applications is 30 cm/sec and at this speed, the initial average fall radius is around 1 cm. This radius allows an effective filter inlet cone 82 diameter of around 2 - 3 cm.
  • the bumps 72 and gullies 70 also act to spread and direct the water into the holes 62 which are usually located in the gullies 70. By using a number of gullies 70, the water flow can be split into smaller streams which are more suited to the smaller holes 62 needed to prevent debris from entering the gutter 22.
  • the main function of the hole 62 is to allow the maximum flow of water through to the gutter 22 and prevent leaves and other foreign materials from getting in.
  • Key elements in the hole 62 design include the number and size of the holes 62 as mentioned earlier. Additionally, the filter pipe design must take into account the interaction of the inlet shape and surface tension, the nature and roughness of the fabrication material, the shape, length and overall angle of the filter pipe and the velocity and direction of the incoming flow.
  • the features of hole 62 design can be grouped as follows
  • Spiralling input streams is one way to assist the entry of relatively fast moving water into the filter holes 62.
  • a 7 mm diameter stream of water spiralling into a 2 cm diameter cone inlet 82 will travel around the cone a circumferential distance of about 5 cm before it encounters its own incoming stream. If the stream of water falls more than its diameter (ie about 7 mm) then the stream of water will not encounter its own stream again and so will continue to spiral down the hole 62
  • This system allows relatively fast moving water to enter a smaller hole than would be the case in direct stream entry
  • the rotation of the earth causes water to naturally spiral down holes in an anti-clockwise direction in the Southern Hemisphere and in the clockwise direction in the Northern Hemisphere. This is called the Coriolis Effect and if the inflow water guides create a spiral direction in the same direction, then the spiralling effect is enhanced and the water flows more quickly If not, the spiralling can still work but it will be retarded by this effect.
  • the inlet cone 82 needs to be designed to handle the spiralling water. This means that the entry lip 80 on the cone 82 needs to be rounded as much as possible so as to keep the water in contact with it.
  • the walls ofthe speed slowing bumps 72 can be used as part of the inlet cone 82 to increase the radius ofthe lip 80
  • the inlet cone 82 also needs to have a relatively steep cone angle if inflow is spiralling This is to overcome the centrifugal force caused by the rotation ofthe water stream and to allow it to fall into the filter hole 62.
  • An angle of less than 40 degrees from the hole axis has been found necessary in tests on roof tiles 20
  • the inlet cone 82 has a cusped lower end 84
  • the angle ofthe wall changes abruptly from around +40 degrees to the axis to around -2 degrees This causes debris objects that are greater than the diameter ofthe cusped hole (7 mm) to be blocked from entering the hole At the cusp 84, the cone 82 angle is large enough to prevent wedging and the debris remains free to move on top of the surface. If the debris object is smaller than the cusped hole 84, then it will fall through and continue down a widening tube 86
  • the final part of the filter tube 62 is the fluted pipe 86
  • the fluted pipe 86 prevents the lodging of small particles as mentioned above
  • the pipe length relative to its diameter needs to be large enough to produce a syphons effect
  • the hole length needs to be at least twice that ofthe average hole diameter.
  • a successful tile 20 developed by the inventor has a hole length of 18 mm and an average diameter of 7.5 mm.
  • GUTTER PRESSURISATION The above systems handle the large majority of debris that land on roads and houses but small amounts of material can sit in the recessed holes 62 and prevent them from functioning properly.
  • the Sadleir gutter tile has the outer lip curved over the lip ofthe gutter 22 with a gap 64 that allows air to enter the gutter chamber 90 and the underside 42 ofthe tile 20 is flat (at the facia sealing surface 66 - shown in Figures 6 and 9) to seal the gutter chamber 90 This causes the gutter chamber 90 to be slightly pressurised when there is wind enter into the slot 64.
  • the pressurisation causes air to clear out the drain holes 62 (arrows 94 in Figure 7).
  • a matching 'gutter tile' 20 made in the same production process and material as the roof tiles gives the best lowest cost and quickest route to the market.
  • the next option could be a soft steel which could be stamped or rolled and punched and then coated or galvanised.
  • the manufacturing cost here is expected be between $1 and $2 per metre of gutter.
  • the two current systems of covering gutters are with concrete mouldings or steel grates.
  • Concrete mouldings would appear to be the preferred process as the set-up costs could be relatively low and the cost per product would also be low.
  • a cover measuring 500 mm x 1000 mm could cost around $50 to manufacture.
  • gutter tiles 20 would be done by the tiler at the same time as the roof.
  • the gutter tile 20 is expected to last the life of the roof and would survive a number of gutter replacements.
  • the gutters 22 remain clean, saving time and money in maintenance for the house owner/landlord and preventing expensive wall and ceiling damage from inward overflow from the gutters 22. 2. Gutters 22 remain clear and dry and this minimises corrosion, giving the gutters 22 much longer life.
  • Lower gutters 22 that is with respect to the top ofthe rafters 26 and the facia 102 used in the system 10 stop overflow from gong back into the house and prevent water damage to walls, ceilings and eaves.
