Abstract
The disclosed rain gutter bracket comprises a mounting member (1) and a support arm
(2). The mounting member has a series of offset surfaces parallel to the abutted fascia
board. The outer surface (1c) of the primary surface (1a) and offset secondary surface
(11) allows for mounting large fixing means, attaching the bracket to the fascia, that do
not impinge on the offset gutter abutted to surface (11). The inner face of the secondary
surface (4), offset to the primary surface (1a), creates a controlled back gap overflow
feature. A support arm portion (2a) is attached to the secondary offset surface (4) and
has an adapted free end (2f,2g) that engages with a hollow reinforcing rib at the upper
end of the front wall of the gutter. The back wall of the gutter (17) engages with a
flexible device (10) held in a containment device (12) that facilities temporary gutter
mounting until finally secured by a fixing means (19) that connects the gutter (17) to the
containment device (12) and via the mounting member (1) to the building fascia surface.
Description
AUSTRALIA Patents Act 1990
The following statement is a full description of this invention including the best method of performing it known to me.
Field of Invention
[001] This invention is concerned with improvements in gutter brackets for supporting rainwater gutters on metal and timber fascia trim.
Background of Invention
[002] Current Australian industry manufacturing practice, for rainwater gutter brackets, is to provide a multitude of parts that should or may include:
• bracket (fascia attachment means) • stiffener (gutter outer edge support arm) • clip (saddle type joiner mechanism) • spacer (a gap means for water overflow)
[003] The major manufacturers produce roll-formed gutters with either a rib or v end form in the rear wall of the gutter. These deformations or folds are intended to not only strengthen the back wall but engage with joining mechanisms that secure the gutter to the fascia.
[004] Prior art that illustrates such joining mechanisms isB16296/95, AU 30239/84,1985046564, 19990051383, 1994064661, 1995016296, 2016222479, 2009222483,2009901600, 2011213740, 2016222479 and 2018278998.
[005]. Another desirable feature may allow for managed water overflow.
[006] Prior art that illustrates a spacer (agap means for water overflow) are 2009222483,2009901600, 2016222479, 2016262775, JP 9-242279, JP 2001 049812 A, AU 2009222483 Al and 2018278998.
[007] In general, all the major Australian manufacturers provide at least two possible solution's one being bottom member brackets (timber fascia) and others (metal fascia) incorporating aspects ofB16296/95. More specifically inward facing projections on the joiner mechanisms (described in B16296/95) that engage with a rib or folded edge formed in the upper portion of the rear wall of gutters are produced by various manufacturers.
[008] Focusing on the invention as disclosed in AU-B16296/95 this was intended to provide a hidden bracket solution in a unitary form that did not require painting to match Colorbond gutters an important design consideration.
[009] It can be shown that the invention disclosed byAU-B16296/95 (and others) is a light duty gutter bracket concerning bending forces, imposed by the centroid of the water mass in the gutter cross section, as the sheet metal support arm transitions into the vertical fascia attachment surface.
[010] In addition, AU-B16296/95 is devoid of a built-in spacer for overflow requirements (NCC Volume Two (Part 3.5.3)). AU 2009222483 Al from the same designers does show a gutter offset design but exhibits the same poor cross sectional water flow profile due to a single sheet piece metal and clipping design which necessitates the support arm descending into the gutter water flow profile.
[011] However, the industry has continued to provide solutions, spring and base members, that AU-B16296/95 was meant to overcome. Non-spring solutions as described in AU-B16296/95 have "a floor member" or "base member" that supports the rear portion of the gutter floor. The base member enhances load carrying capacity in the vertical direction but is inboard of the centroid of the gutter cross section. As a result, they have a lesser effect on gutter rolling tendencies that must be opposed by stiffeners or support arms that project out from the abutted Fascia board and engage in rolled forms of the upper front edge of the gutter.
[012] The identified general problem of painting the "base member" as described by AU-B16296/95 remains.
[013] International Patents JP 2001-049812 A and JP 0 -242279 address the gutter rolling tendencies with deeper support arm sections concerning bending forces imposed by the centroid of the water mass in the gutter cross section.
[014] The gutter outer edge stiffeners or arms on current Australian sheet metal bracket forms generally have a low resistance to bending as a cantilever, in opposing gutter rolling tendencies as the transverse sheet metal arms, transition into the vertical fascia attachment parts of the bracket.
As already mentioned, a major design problem with current gutter single piece sheet metal bracket designs and prior art, including AU-B16296/95 and 1985046564, is that they show bracket forms that project down into the cross sectional profile of the water flow and act to catch leaves and other debris coming off the roofing system. This can be seen in, and others, 1985046564, 1994064661, 1995016296, 2009222483, 20112113740,2026262775 and AU 2009222483 Al. As a result, minimal obstruction to water flow is an extremely important design and operational aspect.
[015] Again, another design problem that affects all gutter brackets is that roll forming is not an exact art for creating sheet metal forms as opposed to stamping, folding or pressing with dies and press tools. As a result, the final roll-formed gutters can exhibit wide tolerances in nominal dimensions in the various rolled forms and shapes.
[016] At the same time current industry installation practice is to, in addition to installing the manufactured bracket parts, install additional screws through the back wall of the gutter and into the fascia board. This identifies installation issues not yet resolved by currently available gutter brackets or identified by prior art nor resolved by those currently experienced in the art.
[017] Therefore, this new invention disclosed within, provides an innovative rainwater gutter bracket that overcomes or ameliorates issues and disadvantages of existing and prior art gutter brackets.
Summary of the Invention
[018] The new invention has a range of advantageous effects not in any specific order as follows:
[019] A primary effect of this invention is to provide a rainwater gutter bracket that can be supplied with or quickly modified on site, with an insertable flexible device, that accepts differing gutter profiles that have specific sheet metal gutter clipping or joining characteristics specific to each manufacturer those characteristics are matched and accepted by the insertable flexible device.
[020] A secondary effect of this invention is to provide a sheet metal rainwater gutter bracket with a separate support arm, in a rod form, welded to the sheet metal.
[021] A tertiary effect of this invention is to provide a variation of the sheet metal rainwater gutter bracket with a formed pocket, in the sheet metal, that allows a separate support arm, in rod form, to be inserted and subsequently float in the vertical direction to allow for gutters with back walls of differing heights to the front of the gutter. The rod form can also be replaced with another rod form possessing a longer or shorter horizontal arm to suit various gutter widths.
[022] A quaternary effect of this invention is providing a rainwater gutter bracket that creates minimal interference with water flow along the length of the channel of the gutter profile.
[023] A quinary effect of this invention is to provide a rainwater gutter bracket that can be installed on metal or timber fascia board and does not require painting to match Colorbond pre-painted steel used in the manufacture of roofing and long run guttering.
[024] A senary effect of this invention is to provide a rainwater gutter bracket to allow the bracket to be fitted with larger fixing means, as in common hexagonal roof screws, that do not impinge on the back wall of the installed gutter. The larger fixing means to increase the strength of attachment to the fascia in timber or metal
[025] A septenary effect of this invention is to provide a rainwater gutter bracket that is offset to the back wall of the gutter to create a controlled back gap in accordance with NCC (National Construction Code) Volume Two (Part 3.5.3).
[026] The rainwater gutter bracket, as disclosed, is preferably made from galvanised steel sheet metal and galvanised steel rod, however, other metals and materials can also be used.
[026] The current invention incorporates all of the above advantageous features in a hidden rainwater gutter bracket solution.

A detailed description of the embodiment or embodiment
[028] It can be seen from Figure 1 that the sheet metal bracket 1 comprises a primary mounting surface la that abuts the mounting face of the abutted fascia board. The sheet metal bracket 1 has a plurality of mounting apertures 8,9, and 9a to facilitate mounting to the abutted front surface of a fascia board with various fixing means. Bracket 1 has an angled stepped form 3 that creates secondary mounting surfaces 4 and 11, parallel to and, at a fixed distance from the frontal face of the abutted fascia board. Attached to the inward-facing mounting surface 4 is a support arm 2. The support arm 2 comprises a vertical member 2a attached to 4, a curved transitional portion 2b, a downwardly inclined portion 2c, a curved transitional portion 2d, a transverse portion 2e, a curved transitional portion 2f and an upwardly inclined portion 2g.
[028a] It can also be seen, from Figure 3, parallel and offset to the secondary mounting surface 11 an outward facing tertiary mounting surface 12, surface 12 also having an opposite inward facing surface 12a, 12 and 12a comprise tertiary mounting surfaces, that in combination with the outward facing secondary surface 11 creates a rigid or semi rigid containment device.
[029] Figure 2 shows the outward face 12 of the rigid or semi-rigid containment formed in the sheet metal of the gutter bracket 1 and an insertable flexible device 10. The rigid or semi-rigid containment device contains the insertable flexible device where the flexible device accepts the vertical back wall of an inserted gutter
The insertable flexible device 10 allows capture and holding of the gutter length for positioning, alignment and fixing needs. The pre-punched clearance and alignment hole 5a in surface 12, in the containment device, aligns with the pre punched smaller diameter pilot hole 5 in surface 4 and allows various final fixing means to lock the back wall of the attached sheet metal of the gutter bracket in its final position. The formed hole 5b in the insertable flexible device 10 aligns with the pre-punched holes 5 and 5a. The vertical surface 11 abuts the abutted back wall 17 of the installed gutter. The axis of the transverse member 2e, of the support arm, is fixed at 90 degrees in the plan view, to the bracket surfaces 11, 1a and as a result at 90 degrees to the line of the abutted frontal surface of the fascia board.
[030] Figure 3 shows the insertable flexible device 10 disengaged from the containment device 12.
[031] Figure 4 shows that the insertable flexible device 10 is formed with a parallel arm 13,14 (second element) that engages with the vertical surfaces of the containment device 12 allowing the inserted flexible device to be positioned and float along the vertical axis and horizontal axes of the surface 12. The flexible device has an internal void 16 that allows the flexible device to bend and flex as the surfaces 15 (first element ) engage with the deformations formed in the back wall of an inserted gutter. The surfaces 15 can be moulded in any shape to suit the back wall deformations of a particular gutter, it can be seen that the various shapes in the flexible device could be angular, circular, folded, projecting, or any combination of a 3-dimensional form. The flexible device can contain multiple shapes that accept more than one gutter profile. Surface 15 can also act as a pressure or friction surface that can hold a flat gutter wall. The insertable device can be replaced by an alternative flexible device at any point from manufacture to installation. The improved gutter bracket can be supplied with one flexible device or multiple flexible devices.
[032] Figure 5 is an isometric view of the fixed gutter installed on the rainwater gutter bracket abutted to the fascia board. The locking screw 19 is clearly shown locking the gutter onto the bracket through apertures 5, 5a (fourth element) and 5b (third element). For installation, the gutter 17 is initially engaged at 17a with the support arm portion 2f and the 2g. The gutter is then manually rotated about the initial engagement points 2f and2g until the back wall of gutter 17 meets the vertical abutted surface 11
[033] Figure 6 is the rear perspective view of the alternative form of the sheet metal showing the formed pocket 20 with the inserted support arm.
