IMPROVED ISOLATION ASSEMBLY

[0001] The present invention relates to an improved isolation assembly, and in particular to an improved isolation assembly, including an isolating hose burst protection valve and water unit combined.

BACKGROUND TO THE INVENTION

[0002] Modern homes require plumbed fittings to be stylish, of course, but also compact, space saving and reliable. Many people live in close communities such as in flats or apartments. In these, or in fact in any home or building a flood is highly undesirable. Many modern homes use a mixer tap with a flexible hose, or a toilet with a similar flexible hose fitting. An issue with the flexible hose fitting is that it is at full water pressure so if there is any damage to the hose, the water will flood out, with nothing stopping the full pressure and flow water. For example, should the flexi-hose break or wear out the water will rush out at full flow and only turning off the water supply will stop the flood. If nobody is home to notice the problem, or if people are home but are asleep, many thousands of litres of water can have flooded out before the accident is noticed and the water flow stopped. Water is highly damaging, and if it floods through several apartments the insurance bill to repair the damage can be very high. Therefore, the present invention seeks a better way to prevent these avoidable flooding incidents through use of an isolating hose burst protection valve.

[0003] The subject invention provides an improved isolation assembly for use with toilet fitting, tap or other plumbed water unit, to act to prevent flooding if the hose itself is damaged. This surprisingly clever invention protects against these kinds of unwanted floods, and enables a bathroom unit to be supplied as a convenient unit with a built-in flood stop valve, removing the need to source and buy the unit of choice and the flood safety valve and flexi-hose to install the unit. In this way the end consumer does not need to buy multiple products but actually a single tap, mixer, toilet, or other plumbed water unit can be supplied all together, with the

specPA2065119 needed flood stop protection, and readily installed. The invention provides a significant advantage over existing system, not only in the flood protection but also the integrated product, to enable easier fitting of a flood protected toilet for example. With the increase of home DIY enthusiasts integrated and readily installed items, with the safety items included is of a very high benefit to the consumer and to the retailer as an attractive package. Further, a societal benefit is provided, to ensure the flood safety valve is installed at the same time as the water unit for most water units in the future.

[0004] The following describes non-limiting examples of the invention being used with reference to being an assembly including toilet in one form, and also optionally a mixer tap assembly. The invention is an extremely useful and beneficial advance on the prior art, and may be provided in a variety of assembled forms, with any water unit, where inclusion of a isolating hose burst protection valve may be useful. For example, the invention may be used for an integral toilet installation, sink, tap, mixer tap, or any other combined installation where the flow control may be of use. It is not intended to limit the invention to the described examples, the invention may be used in any suitable arrangement. However, use for a toilet assembly and, separately, a mixer tap assembly, are particular useful forms of the invention, and as such are specifically defined in the claims.

[0005] For clarity, any prior art referred to herein, does not constitute an admission that the prior art forms part of the common general knowledge, in Australia or elsewhere.

DETAILED DESCRIPTION OF THE DRAWINGS INCLUDING A BEST METHOD

[0075] Referring to Figure 1 and the components of Figures 10 to 45 in particular, isolating hose burst protection valve 10 is illustrated in detail. Isolating hose burst protection valve 10 is provided in the subject invention as a highly desirable and useful complete unit (the rest of components not shown for the first embodiment) for fast installation with guaranteed flood protection. The complete unit includes isolating hose burst protection valve 10, with a flexi-hose connected to the mains supply at one end and plumbed domestic installations such as a toilet or mixer tap at the other, as described fully with respect to the second and third preferred embodiments. The invention is fully directed to this combined unit, of isolating hose burst protection valve, flexi-hose and water unit, to provide a significantly improved flood isolation installation, removing the need to source, and combine each separate component. It would be easy for an amateur installer, to omit the important isolating hose burst protection valve, if the unit was not provided integrally as in the subject invention. The invention enables a DIY enthusiast or skilled amateur to install the complete unit easily, and the floods stop valve is already part of the assembly, even if the installed did not know that this was a desirable inclusion in a professional installation. The all-in-one unit is unique in the

specPA2065119 industry providing strong flood protection and the convenience for the installer to be able to purchase and install a single multifunction unit. The hard work has been done already in the preparation and development by the inventor of this clever invention, to address the growing problem, of potential floods, and in a way that allows simpler, safe installation.

[0076] Isolating hose burst protection valve 10 has housing 20 to house the components in use, allowing desired flow at safe flow rates. Once installed the clever features of isolating hose burst protection valve 10 are hidden by the housing and protected until they are called into action through the water pressure exceeding the predetermined safe rate of 6 litres a minute, as described further below. Housing 20 includes end 22 and inlet 24 for the mains water flow, or other water flow to supply the water unit. Outlet 26 to the flexi-hose enables water flow in usual use to supply the water unit (neither shown for this form of the invention). Rotation through use of a turnable on/off, as known in the art, enables the hole or a blocked face to be presented to allow or block flow of water to the outlet in the usual manner. Separate to the usual on/off controls isolating hose burst protection valve 10 includes flood protection using water-tight assembly 28, with jumper valve and post 32, O-rings 34, 36 and 38, and screw mandrel 40 with grooves 42, end 44, and internal thread 45 are also included. Further gasket 46 can be seen with cartridge cover 48 with ends 50 and 51. End 50 corresponds to end 52 held in by screw 54. Each of these corresponding parts in the second and third embodiments, which is exactly the same as the first embodiment, fits together as shown in Figures 6 and 9 accordingly. The exploded view of Figure is useful for ease of illustration of the components.

[0077] As water flows through isolating hose burst protection valve 10 the water is stopped or allowed to flow, depending upon the status of core 60, with hole 62, and end 64. When hole 62 is in an open position water flow from the attached mains can flow to the outlet and hence to the water unit. In this way when the tap is turned on or the toilet flushed water is sent to the unit in the normal manner, as

specPA2065119 flow is open and able to occur. Spring 66, O-ring 68, spring holder 70 and circlip 72 together are arranged so that spring 66 is bias towards the outlet.

[0078] Water is passed through the inlet side 24 and core 60, bypassing water tight assembly 30 and is biased towards water outlet 26 at a pre-determined flow rate (in the open position). When the pre-determined rate is exceeded, usually the result of a damaged water hose or damaged water inlet device, the expected volume of water will exceed the predetermined flow rate of the isolating hose burst protection valve 10 resulting in the core 60 and spring assembly 66 forcing the water shutoff to the biased outlet.

[0079] Through use of the invention, installation is a straightforward process. The water unit is connected to the flexi-hose, with isolating hose burst protection valve such should the flow exceed the pre-set parameters of the valve, that is exceeding flow of 6 litres per minute, flow is stopped entirely. It is not pressure of the water that will cause the shutoff, as this can vary through the day, but rather the flow rate exceeding 6 litres per minute thereby activating isolating hose burst protection valve to stop all flow. In this manner, the clever invention provides an excellent manner of hose burst flood prevention, automatically in response to the flow rate exceeding 6 litres per minute.

[0080] Referring to Figures 2 to 6, and the components of Figures 10 to 43 of the isolating hose burst protection valve 110, a second preferred embodiment of the invention will be described isolating hose burst protection valve assembly 105, where isolating hose burst protection valve 110 is provided as a combined unit with a toilet. Isolating hose burst protection valve 110 works in exactly the same way as described for valve 10, but is described as the entire assembly.

[0081] Isolation assembly 105, includes valve 110 with housing 120, end 122 and inlet 124 for the mains water flow, and outlet 126 to the water unit for this particular invention, as described for the first embodiment. Water-tight assembly 128 is

specPA2065119 included, with jumper valve 130 and post 132, O-rings 134, 136 and 138. Screw mandrel 140 with grooves 142, end 144, is included with an internal thread 145. Gasket 146 can be seen with cartridge cover 148 with ends 150 and 151. End 150 corresponds to end 152 held in by screw 154.

[0082] Toilet suite 80 is plumbed in the usual way for the waste, including waste outflow pipe 82. Isolation assembly 105 includes toilet suit 80, water restrictor 84, flexi-hose 90, with end 92, and isolating hose burst protection valve 110, provided as a total unit a isolating hose burst protection valve safety toilet assembly.

[0083] As water flows from the mains supply through inlet 124, water can flow to toilet 80 in the usual way, so if flushed water flows and then refills the cistern. The water flows through isolating hose burst protection valve 110, flexi-hose 92 and water restrictor 84, which maintains suitable water pressure. As shown water restrictor 84 is a 6 litres a minute restrictor. Again, the status of core 160, with hole 162, and end 164 is important, and will allow or prevent the flow of water. Spring 166, O-ring 168, spring holder 170 and circlip 172 again cooperate together so that spring 166 is bias towards the outlet.

[0084] Any and all forms of toilet may be used with the invention to provide a flood stop isolation assembly including a toilet for an improved toilet installation.

[0085] Referring to Figures 7 to 9, and the components of Figures 10 to 45 a third preferred embodiment of the invention will be described, including isolation assembly 305, with isolating hose burst protection valve 310. Isolation assembly 305 is provided as a combined unit with a mixer tap 94, and two flexi hoses to provide hot and cold water in a way that is protected with a flood safety valve.

[0086] The mixer tap form could be adapted for any suitable for use in any domestic or commercial application. The tap may be for a sink such as in a bathroom or in a kitchen, and as illustrated is described as a mixer tap installed in a kitchen

specPA2065119 benchtop (not shown). The mixer tap as illustrated is 160 millimetres in height above the bench top extends 230 millimetres with an outlet 120 millimetres above the bench top. A water restrictor valve is included between the flexi-hose inlet sand mixer tap 94 to restrict flow to 6 litres a minute.

[0087] Similar to the previous two embodiments, isolation hose burst protection valve assembly 305, includes valve 310 with housing 320, end 322 and inlet 324 for the mains water flow, and outlet 326 to mixer tap. Water-tight assembly 328 is included, with jumper valve 330 and post 332, O-rings 334, 336 and 338. Screw mandrel 340 with grooves 342, end 344, is included with an internal thread 345. Gasket 346 can be seen with cartridge cover 348 with ends 350 and 351. End 350 corresponds to end 352 held in by screw 354.

[0088] Referring to Figures 10 to 12, circlip 72, 172, and 372 is illustrated, of isolation valves, 10, 110 and 310. Circlip 72, 172, and 372 is made of metal and has a diameter to the outer perimeter of 13.7 millimetres.
