It is to be appreciated that each of the embodiments is specifically described and that the present invention is not to be construed as being limited to any specific feature or element of any one of the embodiments. Neither is the present invention to be construed as being limited to any feature of a number of the embodiments or variations described in relation to the embodiments.
Referring to
The roof rain gutter system 10 includes a drainage pipe 14 that is positioned within and extends along the gutter 12. A coarse heavy filler material 16 (not shown) in the form of crushed stone is placed on top of the drainage pipe 14 and allows the passage of rain water into the drainage pipe. In addition the coarse heavy filler material 16 assists with holding the drainage pipe 14 in position.
In the system 10, a rain guttering component 18 is positioned above a drop outlet 20 of the gutter 12. The rain guttering component 18 is configured to direct water flowing through the drainage pipe 14 downwardly into the drop outlet 20. Advantageously the rain guttering component 18 is adapted to surround the drop outlet 20 to prevent the passage of coarse heavy filler material 16 through the drop outlet 20.
The weight of the coarse heavy filler material 16 is supported in the retrofit with the use of a bracket arrangement 22 shown in
The coarse heavy filler material 16 is provided in the form of coarse construction aggregate. The aggregate 16 is preferably large enough to resist the flow of fluid and provide advantageous drainage into the drainage pipe 14. The drainage pipe 14 comprises corrugated drainage pipe.
The system 10 is considered to provide an advantageous filter system where conventional drainage pipe can be advantageously accommodated in gutter systems of different sizing. When the drainage pipe 14 is slightly smaller in cross section than the gutter, the coarse heavy filler material 16 fills the remaining space on one or both sides of the gutter 12. The functionality and adaptability of the system 10 is considered to provide several commercial advantages over existing systems such as foam filter systems.
It is considered that the use of two or three different drainage pipe sizes is suitable for the most commonly used sizes of roof gutter. The stone aggregate filling the gutter space creates a three dimensional filter before rain water is carried by the drainage pipe and is directed through the drop outlet.
In addition the system advantageously allows for retrofitting to gutters having internal brackets. This is achieved by the drainage pipe 14 being threaded underneath the internal brackets before the coarse heavy filler material 16 is applied. The system 10 also allows for fitting into gutters where the roof partly extends over the gutter opening which is one problem of several existing systems.
The coarse heavy filler material provides a relatively flat surface without relatively large recesses that would otherwise accumulate leaf material. The system 10 is considered to assist with preventing leaves and other debris from collecting in the top of the gutter 12.
The use of the coarse heavy filler material 16 also serves to protect the drainage pipe 14 from exposure to the sun and the weight of the coarse heavy filler material 16 serves to assist with securing the drainage pipe 14 in position.
The use of coarse heavy filler material 16 may also be of benefit in a bush fire situation. Firstly by preventing the accumulation of leaf material and secondly, to a lesser degree, by protecting the plastic drainage pipe itself. In addition, with stones, they assist with preventing embers from entering the roof cavity as they bridge the gap between the gutter and roof.
A method 28 of installation of the roof rain gutter system 10 is illustrated in
In some instances fasteners in the form of tek screws are used to hold the drainage pipe and fittings together before placement of the stones. Other fittings that may be needed for the drainage pipe include joiners, right angle bends and end plugs.
The form of the roof rain gutter component 18 is highlighted in
As shown the first fluid port 38 is arranged at about 90 degrees to the second fluid port 40. The portion 42 of the body 36 between the first fluid port 38 the second fluid port 40 provides a cover portion 44 for preventing the passage of coarse heavy filler material 16 through the drop outlet 20.
The first fluid port 38 is arranged as channel open at both ends 46. Notably a cover portion 48, shown in
Referring to
The form of the body 36 provides the first fluid port 38 with two opposite openings 60 for allowing connection to a drainage pipe on either side. Each opening 60 of the first fluid port 38 is adapted to connect to drainage pipe extending along the gutter 12 or alternatively, be closed by the closure 48.
In practice, the drainage pipe 14 and the coarse heavy filler material 16 may be purchased separately. The provision of the roof rain gutter component 18 and brackets 24 may be provided as a kit for providing the system 10.
Components for circular gutters could also have such protrusions. Nonetheless a component 160 forming another preferred embodiment is shown in
The roof rain gutter component 18 and the roof rain gutter system 10 individually and as a whole are considered to be advantageous. The applicant has also designed a number of advantageously brackets described below.
Referring to
a and 13b show another bracket 200. Advantageously with this bracket a hole can be drilled into the face of a wall 210, or otherwise, and the upper end 212 of the bracket fitted therein. A number of the brackets can be placed in series around the outside of the wall to support a length of guttering. The bracket 200 is considered to be particularly useful when attaching to thin material such as roofing iron.
In the case of a facia, the facia would be thicker than the roofing iron. In such a case it is considered that it would be more practicable to use a bracket (such as bracket 68) that screws on. In the case of the bracket 200 there is an offset 214 in the design to accommodate the roofing iron.
The bracket 200 when designed for a different thickness material has a different offset. It is considered that the bracket 200 is a particularly good bracket for use in the situation of attaching to thin metal as it has a good holding force.
Referring to
More particularly the first portion 82 is formed by bending a first flange portion 90 along a first fold line 92. The second portion 86 is formed by bending a second flange portion 94 along a second fold line 96. Advantageously a third fold line 98 is provided on the second flange portion 94 for overlapping the first portion 82. As shown in
As shown in
The reason for the extension 148 is removable to allow a person to install the gutter onto the bracket. Current brackets are all one piece and do not require this because the gutter is installed by engaging the outer lip of the gutter into the hook of the bracket and then swung up into position. The brackets have a small ledge of 10 mm deep to hold the bottom back edge of the gutter or they have a clip mechanism to engage and hold onto the inside top edge of the gutter.
With the present bracket the supporting member 145 prevents installing in this manner. Rather, the gutter is placed on the supporting member 145 and then the extension piece is engaged in the gutter lip, rotated and fastened to the member 144 with a tek screw through the holes provided.
The extension piece 148 could be screwed together at a different location however in this embodiment the brackets are made to match each individual gutter profile that should rarely be needed.
With the currently used brackets the gutter lengths are joined together as much as possible while the gutter is hanging down and then is swung up into position. Installing using the present brackets is considered to be advantageously easier as the gutter is supported in its final position before being joined and attached.
As shown in
In addition in this embodiment the member for mounting to a supporting structure 140 is strengthened by having a flange 218 on each side to form a shallow channel that is deep enough to accommodate the head of a tek screw bolt. This also creates a gap between the supported gutter and the facia that it is attached to. This is considered to provide an advantageous gap for overflow.
Furthermore the bracket 138 made from single piece of sheet metal (not including the attaching clip 148).
Furthermore, one feature of the bracket 170 is that that is it can be firstly attached underneath the gutter before it is closed together. This advantageously facilitates the easy insertion of the screw through a hole 178 and into whatever it is attached to, as an extension driver, be it a screw or socket driver, can fit between the open gap, thus allowing it to be square onto the head of the screw. The bracket 170 is sold in the open state, and once securely attached, it is simply a matter of bending up the bottom brace 176 and at the same time springing up the top member 180.
In this case the bottom brace 176 is bent up until the end of the bottom brace clears the end of the top member 180. The top member 180 is then let to spring back into its right angle position and the end of the bottom brace 176 engages into the groove 182 of the top flange. Folding over the end of the top member 180 is considered to be advantageous.
As shown, the hole 178 allows the bolt to pass through, which this design allows to be located near the top of the bracket, which results in it being possible to make the back of the bracket shorter than an equivalent bracket without a brace member. (As the material is much thicker the bolt hole must be further down.) There are two reasons why this is an advantage. First there can be a lack distance between the bottom of a gutter and the edge of the supporting facia board or other member. Secondly they are more aesthetically pleasing and less noticeable if they have less depth.
A slot is preferably positioned at location 216 at the bend of the brace section to facilitate it bending at that spot instead of it flexing or bending along the brace or back section when it is forced up.
As would be apparent there are to different types of brackets disclosed herein. The first type are those that are used to provide extra support under the gutters. These are all right-angle brackets secured under the gutters. The second type are a replacement for the currently used brackets. These would be used when installing a new gutter and do not require the additional strengthening brackets.
It is considered that current brackets used in Australia have two major design defects. Firstly, they do not positively resist downward force. As they have no bracing component to prevent the gutters from sagging the more weight of material in the gutter the more the gutter sags.
Secondly, the back portion of the bracket where they are mounted to the facia board is flat. There is no provision for the head of a bolt as they were designed to be used with flat headed nails. These often work their way out over time.
Whilst tek screws are now usually used but even the minimal head types still protrude more than the flat headed nails. This does not allow the gutter to sit in the bracket correctly and it precludes the use of tek screws with socket heads.
Many of these brackets only have one hole at the top which is offset to one side due to the design of the top member of the bracket. This makes them difficult to satisfactorily attach to roofing iron clad walls or other situations where the mounting surface is not flat or as wide as the bracket.
In summary, preferred embodiments of the present invention are considered to provide a number of systems and methods including those that advantageously:
The brackets are considered to provide further embodiments of the present invention.
It is to be recognised that various alterations and equivalent forms may be provided without departing from the spirit and scope of the present invention. This includes modifications within the scope of the appended claims along with all modifications, alternative constructions and equivalents.
