Abstract

A side outlet device suitable for use in combination with a rainhead to form an overflow assembly is adapted to enable the rainhead to be mounted external to the building in relation to a wall of the building, to one side of a box guttering extending interiorly along the wall, whereby water flowing from the roof is able to pass through the side outlet device to a downpipe via the overflow device. The side outlet device has a respective end section at first and second opposite ends, with the first end section having a form corresponding to the form of a box gutter end section such that, with the side outlet device mounted in relation to the wall, the first end section extends through the wall and is receivable in the gutter receptor of the overflow device. The second end section is adapted for connection to the box guttering to enable water to flow from the box guttering and through the side outlet device to the overflow device.

Dependent claims

A side outlet device, suitable for use in an overflow assembly including a combination of the side outlet device and a rainhead, the overflow assembly mountable, in relation to a roof area, adjacent to an outer a wall of a building, the side outlet device to be in communication with the rainhead, the rainhead to be mounted on an external side of the wall opposite box guttering extending along an interior side of the wall, whereby water flowing from the roof area and along the box guttering is able to pass, in turn, through the side outlet device and the overflow device to a downpipe of the building, the side outlet device comprising:

an elongate body extending between first and second opposite ends of the body, the body formed by at least two sections adapted for sealable longitudinal inter-fitting, the at least two sections including a first end section at the first end of the body and a second end section at the second end of the body, the body including:
a first side wall extending along a first side of the body;
a second side wall extending along a second side of the body opposite the first side;
and
a base wall extending between the first and second side walls, the first side wall, the second side wall, and the base wall defining an open-topped channel extending between the first and second end sections, the open-topped channel having a U-shaped cross-section;
the first end section having a form of a box gutter end section adapted for communication with the rainhead;
the second end section including:
a lateral wall extending across the channel transverse to the first and second side walls;
and
a U-shaped lateral inlet defined in at least one of the first side wall or the second side wall, the inlet having a lower edge spaced apart from the base wall of the body;
and
a flange adjacent a peripheral edge of the inlet to facilitate lateral connection of the inlet to an end outlet of the box guttering to enable water to flow from the box guttering laterally into the channel and then flow longitudinally from the second section of the body to and through the first section of the body, and into the rainhead.

an elongate body extending between first and second opposite ends of the body, the body formed by at least two sections adapted for sealable longitudinal inter-fitting, the at least two sections including a first end section at the first end of the body and a second end section at the second end of the body, the body including:
a first side wall extending along a first side of the body;
a second side wall extending along a second side of the body opposite the first side;
and
a base wall extending between the first and second side walls, the first side wall, the second side wall, and the base wall defining an open-topped channel extending between the first and second end sections;
the first end section having a form of a box gutter end section adapted for communication with the rainhead;
the second end section including:
a lateral wall extending across the channel transverse to the first and second side walls;
and
a U-shaped lateral inlet defined in at least one of the first side wall or the second side wall, the inlet having a lower edge spaced apart from the base wall of the body;
and
a flange adjacent a peripheral edge of the inlet to facilitate lateral connection of the inlet to an end outlet of the box guttering, the base wall to be lower than the flange and lower than a sole of the end outlet of the box guttering to facilitate hydraulic operation of the side outlet device by creating a knickpoint for water flowing laterally into the channel from the box guttering, the water to then flow longitudinally from the second end, to and through the first end of the body and into the rainhead.
