DESCRIPTION OF EMBODIMENTS

[0042] Referring now to Figures 1 and 2, there is shown a valve assembly 1 for a gutter outlet or downpipe according to an embodiment. [0043] The valve assembly 1 comprises a valve body 2 comprising an inlet 4a, an outlet 4b, a passageway 4 extending between the inlet 4a and the outlet 4b, and a closure element 10 movable between an open position and a closed position with respect to the passageway 4 through the valve body 2.

[0044 ] In a typical installation, the inlet 4a of the valve body 2 is connected to an outlet for a gutter, and a downpipe (optional) is connected to the outlet 4b of the valve body 2. In an alternative, the valve assembly may be installed between lengths of downpipe.

[0045] When the closure element 10 is in its open position (as illustrated in Figures 1 and 2), water from the gutter may flow through the passageway 4 and into the downpipe. When the closure element 10 is in its closed position (as illustrated in Figure 10) it blocks the passageway 4, preventing flow therethrough, and causing water to be collected in the gutter.

[0046] The closure element 10 comprises a shutter 10 movable by way of a translation. The shutter 10 comprises a generally planar and elongate body 12, where the body 12 curves in the direction of its elongation, and comprises a pair of substantially parallel sides extending in the direction of its elongation.

[0047] The valve assembly 1 further comprises a shutter housing 20 depending from the valve body 2. The shutter housing 20 is adapted to house the shutter 10 when this is in its open position with respect to the passageway 4 through the valve body 2. The shutter housing 20 comprises a generally planar and elongate housing body which extends outwardly from the valve body 2, curving downwardly (i.e. in the direction of the outlet 4b) as it extends outwardly from the valve body 2. In this respect, the curvature of the shutter housing 20 substantially matches the curvature of the shutter 10.

10048] The shutter housing 20 further comprises a pair of substantially parallel sides 22 extending in the direction of its elongation. Each of the parallel sides of the shutter housing 20 comprises a shutter guide track (or slot) internally, for guiding the sides of the shutter 10 as it translates (or slides) between its open and closed positions.

[0049] With reference to Figure 10, it can be seen that where the shutter 10 intersects the passageway 4 of the valve body 2, the valve body 2 seats sealing elements 15 (O-rings in this case) above and below the shutter 10, to prevent water from leaking past the shutter 10 when this is in its closed position.

[0050] An underside (or outlet side) of the shutter housing 20 comprises a slot 24 extending from its outermost end in the direction of its elongation. [0051 ] An underside (or outlet side) of the shutter 10 comprises a rigid tab 14 projecting outwardly therefrom at a position towards its outermost end. When the shutter 10 is assembled in the valve body 2 and shutter housing 20, this rigid tab 14 extends through the slot 24 in the shutter housing 20, and is guided in the slot 24 as the shutter 10 translates (or slides) between its open and closed positions.

[0052 ] The tab 14 is laterally curved so as to define a concavity. Together with the underside of the shutter 10, the concave side of the tab 14 defines a socket 30 which, when the valve assembly 1 is in use, is generally directed in a downward direction (i.e. toward the outlet 4b) for receiving an end of a pole-like member.

[ 00531 In use, when, as is the general case, there is no threat posed by fire, the closure member 10 of the valve assembly 1 will be set in its open position (see Figure 2), so that the gutter can drain normally through the passageway 4 of the valve assembly 1.

[ 00541 In use, in the event that a fire does threaten the building, a user can quickly and easily move the shutter 10 of the valve assembly 1 from its open position (see Figure 2) to its closed position (see Figure 5) with respect to the passageway 4, by inserting an end of a pole-like member (such as a broom handle) into the socket 30, and pushing in an upwardly direction at least, causing movement of the shutter 10 up and out of its shutter housing 20 and into its closed position in the valve body 2, in which position the shutter 10 substantially obstructs the passageway 4. The gutter can then be filled with water using a hose or sprinkler, reducing the risk that material caught in the gutter can be set alight by embers.

[0055J This upwards pushing action is significantly easier to effect from below, and/or using a pole-like member, than is a sideways pushing action. Moreover, the ability to effect closure of the valve assembly 1 from below, and without need for a ladder, makes operation of the valve assembly 1 quicker, easier and safer than the operation of other valves.

[0056] When the threat of fire has passed, a user can move the shutter 10 of the valve assembly 1 from its closed position to its open position with respect to the passageway 4, by pulling downward on the tab 14. For convenience, a wire or string can be secured to the tab 14 via a hole therethrough, and the shutter 10 opened by pulling downward on the wire or string.

[0057] In the case of the illustrated embodiment, the valve body 2 and shutter 10 are moulded from a PVC-U (although its material need not be so limited), and the shutter housing is integrally moulded with the valve body 2. [0058] Referring now to Figures 3 and 4, where there is illustrated a heat shield assembly 50 for protecting the plastic valve assembly 1 from the radiant heat of an approaching bushfire threat, without interfering with its function.

[0059 ] The heat shield assembly 50 comprises a pair of attachment clamps 52, an outer heat shield element 54, and an inner heat shield element 56, both of zinc plated powder coated steel, and supported by spacers 58 depending from the attachment clamps 52 (optionally clips could be used). The inner and outer heat shield elements 56 and 54 are spaced apart from each other, and the attachment clamps 52 (and thus the valve assembly 1 in turn), by the spacers 58.

[0060] With reference to Figures 5 through 1 1 , it can be seen how in use, the heat shield assembly 50 can be positioned as required, and secured with respect to the valve assembly 1 using the attachment clamps 52, which clamp around the valve body 2.

[0061 1 In use, in the event that a fire does threaten the building, the outer shield element 54 shields the valve assembly 1 from direct radiant heat, while the inner shield element 56 helps reduce a temperature at the valve assembly 1 by way of a flue effect. In an alternative design, only one shield element may be employed.

[0062] Throughout the specification and the claims that follow, unless the context requires otherwise, the words "comprise" and "include" and variations such as "comprising" and "including" will be understood to imply the inclusion of a stated integer or group of integers, but not the exclusion of any other integer or group of integers.

[0063] The reference to any prior art in this specification is not, and should not be taken as, an acknowledgement of any form of suggestion that such prior art forms part of the common general knowledge.

[0064] It will be appreciated by those skilled in the art that the invention is not restricted in its use to the particular application described. Neither is the present invention restricted in its preferred embodiment with regard to the particular elements and/or features described or depicted herein. It will be appreciated that the invention is not limited to the embodiment or embodiments disclosed, but is capable of numerous rearrangements, modifications and substitutions without departing from the scope of the invention as set forth and defined by the following claims.
