Definitions
- the present invention relates to the field of connectable structures for use in residential properties, industrial properties, municipal parks, gardens or indoor/outdoor spaces.
- the invention relates to a connector system for use in the connection of liquid reservoirs, which may include tanks and, is particularly suited for use in equalising connected reservoirs and/or the liquid stored in such reservoirs.
- the present invention will be described with reference to a rain water tank for use at a residential property, it should be appreciated that the present invention is not so limited and relates more generally to liquid storage reservoirs used in a wide range of applications. In particular the present invention may be used for non-residential purposes, such as in industry or farming.
- one existing method of connecting tanks includes using a pipe of any convenient material to connect pre-cast ports of adjacent tanks and placing a washer and nut (or similar) at each end of the pipe to tighten the pipe in the port.
- this method of connection can start to fail as the tank and pipe expand and contract over time causing the fasteners to strip or damage the tank.
- Another existing method of connecting tanks includes using a fitting such as a threaded metal screw that is fixed cast into the tank to define the port.
- a pipe with a corresponding thread at each end cap then be screwed into the port.
- the lack of flexibility in this arrangement can cause damage to the tank during fitting, or stripping of the thread in the port.
- independent movement of a tank places stress on fixed cast fittings and may damage, stretch or crack the side wall of the tanks.
- Sealant can also be applied in an attempt to achieve a watertight seal between a pipe and port in a tank.
- sealant may not seal properly if the material is wet or in the presence of aggregate or 'blow holes' or aggregate holes at the port of a pre-cast concrete tank.
- sealants are not suitable for total submersion in water, some dry hard and are prone to cracking under stress, and some become porous over extended periods of time. Repairing a leak due to sealant failure is a time consuming and expensive process.
- some tanks are provided with an integral, connector that is typically cast into the tank when it is fabricated.
- connectors sold under the name CAST-A-SEALTM are made of rubber and cast into concrete tanks.
- the connector is simply tightened around a pipe using a stainless steel take-up clamp. This is of course impractical when the tanks to be joined are abutted to each other.
- Such a device is reliant on the installer to ensure an external band is tightened correctly or not damaged in any way.
- the connector is not fitted correctly or damaged due to independent movement of a tank or the pipe or corrosive properties effecting the tightening band, it is difficult to repair and it may be necessary to go through the expensive process of replacing the entire tank.
- some tanks have an integral polymeric connector known as a 'press seal'.
- a 'press seal' the entire tank becomes unusable if the O-ring included in the device is abraded or otherwise damaged by careless installation or independent movement of adjacent tanks.

- a first liquid reservoir 101 is located adjacent a second liquid reservoir 102, each reservoir having a respective first port 105 and second port 106.
- a further reservoir may be. positioned adjacent the second reservoir and connected in a similar fashion to that described herein and this may be repeated for any number of further reservoirs connected in modular fashion.
- the reservoirs are located In a row, or at right angles to adjacent reservoirs.
- a conduit 107 is in communication between the two reservoirs, either end of the conduit 107 being located through the respective ports 105 & 106.
- two first seals 109a & 109b in the form of O-rings are located in the first port 105 and encircle one end of the conduit 107.
- Two second seals 110a & 110b are located in the second port 106 and encircle the other end of the conduit 107.
- the seal means shown in the preferred embodiment herein of figure 1 is not limited to use of O-rings as there are forms of seals that provide a similar function in sealing the conduit in accordance with the present invention.
- a number of variations on seal formation including but not limited to channel rubber or sealing strips may be incorporated into the structure of liquid reservoirs disclosed herein.
- figures 6A to 6C show an alternate sealing means to the conventional O-ring.
- suitable variants of seals for the purposes described herein are commercially available from a number of suppliers in the market and a number of appropriate examples are depicted in product information available at http://www.ormistonrubber.com.au/general.php.
- the walls of the first liquid reservoir 101 and second liquid reservoir 102 are each of a thickness of 100 to 150 mm or more. Hence the combined wall thickness when the reservoirs are abutting is 200 to 300 mm or more.
- the reservoirs 101 & 102 are shown in Figure 1 as defining a rectangular space; it is to be understood that this is a preferred form and that the reservoirs 101 & 102 need not be of constant horizontal cross-sectional shape and need not even be rectangular In horizontal cross section, as is described in conjunction with other figures of this specification.,
- the reservoirs may be manufactured of any convenient material such as moulded polymeric material such as UV-stable frost and heat resistant polypropylene, or cast concrete.
- the reservoirs 101 & 102 have a storage capacity in the range of from about one thousand litres to about two thousand litres.
- the conduit 107 is therefore typically 200 to 300 mm or more and can be manufactured of any convenient material such as PVC.
- the seals 109 & 110 are able to be independently removed from the conduit and their respective ports 105 & 106.
- the ports 105 & 106 are configured to include a seat for each seal 109 & 110.
- the seat may be formed by any convenient means, such as by forming an appropriately shaped recess during casting of the liquid reservoir.
- the seals 109 & 110 are O-rings the seat may be of circular, square or polygonal shape as convenient for cross sectional shape of the O-ring.
- the connector may comprise a conduit 115 having one end located through a first port 117 formed in the wall 119 of a first reservoir, and the other end located through a second port 118 formed in the wall 120 of a second reservoir.
- the periphery of each port 1.17 & 118 may be cast to include a seat of any convenient shape for a first seal 122 and second seal 123 respectively.
- the ports 117 & 118 may comprise an appropriately recessed formation such as a taper at their inner and/or outer ends in cross section as shown so that the conduit 115 can move without touching the periphery of the ports 117 &118 or breaching the watertight sealing of the connection.
- non-return valves may be provided, either in association with the conduit 115 or as a separate fitting.
- the reservoirs 101 & 102 may be suitably reinforced to withstand pressure loadings from the liquid contents and to provide adequate support for loading from garden beds and the like.
- the reservoirs 101 & 102 are provided, either integrally or as an attached component, with skids or other mechanisms to allow ease of movement and handling.
- Each reservoir may also have structural reinforcing support by way of ground engaging means incorporated into the structure to
- retaining wall support mechanisms such as flat plates and/or horizontal divides to prevent tanks from moving when empty. Soil from a retaining wall may be placed against a reservoir 101 or 102 and in a counter force also holds water tank stable from movement.
- These support mechanisms may be further stabilised by devices driven into the ground such a star pickets or the like.
- the support mechanisms may be of any suitable size or configuration and may be an integral moulding or add-on as required, as would be recognised by the person skilled in the art.
- Figure 2A is a cross-sectional view being an enlargement of a port 105A of a liquid reservoir 101 in accordance with an embodiment of the present invention showing a seal means 109a for sealing around a conduit 107.
- An exaggerated taper 201 is applied to the wall of the reservoir 101.
- Figure 2A omits the seat for the seal means 109a for the purpose of illustration.
- Figure 2B is another cross-sectional view also being an enlargement of a port 105B of a liquid reservoir 101 in accordance with a preferred embodiment of the invention.
- Seal means 109b is used to seal a conduit 107 within the port 105B.
- a taper 202 is again applied to the wall of the reservoir forming the port 105B and is exaggerated in figure 2B for the purpose of illustration.
- a seat 203 which in this particular embodiment protrudes out from the edge of the orifice in the port 105B so as to assist in preventing the conduit touching the side of the reservoir wall.
- ports 105, 106 etc are lined up to accommodate conduit 107 for the flow of liquid therebetween.
- the side walls of the ports of the tanks are tapered to prevent the conduit or pipes touching the wall(s) of the tanks which could cause unwarranted pressure on the pipes and sealing means as a result.
- Seal means in the form of casting or O-rings are seated or cast in PVC moulding and protrude, in a preferred embodiment, out from the edge of the orifice so formed by the ports so as to also prevent pipe touching the side of the tank walls.
- FIGs 2A and 2B only one O-ring is used per tank.
- the protrusion so formed may be sufficient in certain embodiments to prevent the conduit from touching the walls of the reservoir without the need for a tapering of the reservoir wall(s).
- one option is to cast a shape in the wall of a concrete reservoir and then the seal, preferably an
- O-ring may be pushed into the formed shape to provide the seal.
- a PVC sleeve or an equivalent component of predetermined shape may be cast into the reservoir wall to house a removable O-ring, for example.
- the shape of the orifice of the reservoir may be so designed that it has a small taper to also prevent the pipe/conduit from touching the side of the concrete reservoir. That means the only point of seal is the pipe or conduit on the seal or seal.
- the other way of achieving this is to make the orifice large enough and the seal protruding to provide enough space around a removable O-ring so as not to touch the concrete wall. If the pipe was to press against the concrete wall of the tank there is a possibility the O-ring may not seal correctly in the event the structure moves somewhat. In a most preferred form, it is intended to use only one O-ring per tank wall.
- Figures 3 and 4 illustrate how three reservoirs 120, 121 & 122 may be placed side by side and plumbed together using the connector of preferred embodiments of the present invention to create the appearance of a stepped garden bed.
- the downpipe is aligned with an aperture 126 which is in turn aligned with a filter assembly (not shown) that discharges filtered water into the reservoir 122.
- one or more of the reservoirs may be positioned at right angles relative to at least one adjacent reservoir.
- Each of liquid storage reservoirs 120, 121 & 122 is mounted with containers 129a, 129b & 129c suitable for Use as garden beds.
- containers 129a, 129b & 129c suitable for Use as garden beds.
- other structures may be alternately formed or provided at the top of or- adjacent one or more reservoirs so that the system can function otherwise as, for example, a garden seat or table top or other device for outdoor furniture use.
- the containers 129a, 129b and 129c have drainage channels in their bases to allow water to freely move along the bases to allow hydroponic .cultivation.
- water is pumped through the container with pump and then to waste or back into one of the liquid storage reservoirs 120, 121 or 122 for recirculation.
- inventions of figures 1 to 5 may further comprise attachment points for the attachment of external cladding, mouldings or the like.
- external cladding or mouldings may comprise natural or artificial timber or stone, or other decorative material.
- connection system of the present invention is now described.
- FIGS 6A to 6C show an embodiment of the connection system where a moulding 601 of suitable material is engaged into the internal wall of the reservoir forming the port 106 or 105.
- the moulding 601 has an integral barrier 603 comprising an , integral flange and furthermore, the moulding also comprises sealing means' 602 adapted for making a liquid tight seal with the conduit 107.
- sealing means' 602 adapted for making a liquid tight seal with the conduit 107.
- Figures 7A to 7C also show a moulding 701 for engagement with the internal wall of the ports 105, 106.
- the internal walls are recessed to form a tapered cross section.
- the moulding includes internal flanges
- the moulding 701 is also adapted for engaging a separate sealing means
- the moulding 701 includes an integral flange for forming a barrier 703, best shown in figure 7C 1 that will work in combination with the tapered recess of the internal walls of the ports 105, 106 to restrict contact between the conduit 107 and the structure of liquid reservoirs 101 , 102.
- FIG 8A to 8C 1 there is an example shown that omits a moulding and in place has a concrete moulding of the reservoir itself to form the internal walls of the ports 105, 106.
- the walls are also tapered in this example and in combination with the O-ring seals 802 are adapted to restrict contact between the conduit 107 and the liquid reservoirs 101 , 102.
- Figures 9A to 9C show an example of a variation in the embodiment shown in figures 7A to 7C that omits the internal flanges 704 that are shown in figures 7B and 7C. In all other resects the embodiment of figures 9A to 9C is the same as that shown in figures 7A to 7C.
- connection system as described herein provides for a convenient and effective means of allowing liquid to flow between adjacent reservoirs and thus equalise the liquid contained therein. Furthermore, with the benefit of restricting contact between the conduit 107 and the structure of the liquid reservoirs 101 , 102 particularly when relative movement between reservoirs may occur in a number of circumstances, it is possible to maintain an equilibrium between adjacent reservoirs or tanks as the case may be.
- a seal internal to the tank or reservoir walls is provided with a seal of any sort or similar to an O" ring which may or may not be removable and with the edges of the tank wall at such an angle to allow substantial conduit or PVC pipe movement without hitting the side of the tank walls thus causing leakage.
- "cast in place” seals be a further option and incorporation of a large flange cast into the tank structure with an internal "O" ring structure may suffice.
- the O" ring structure and flange combination are designed to not protrude past the side or edge of the tank to interfere with the abutment of each tank to the other.
- a large flange incorporating "O" ring and external taper of tank wall provide flexibility for movement of tanks for any reason.
- This particular embodiment allows conduit or PVC pipe to be easily pushed between two adjoining tanks and provide an adequate seal.
- the internal "O" ring seal is not removable and is to be manufactured from suitable materials to ensure integrity of the "O" ring seals are maintained at all times. While this invention has been described in connection with specific embodiments thereof, it will be understood that it is capable of further modification(s).
- a seal means which may comprise at least one "O-ring” component that is fixedly andtar permanently mounted into a port of a structure, which may be in the form of a liquid reservoir.
- a suitable "O- ring” component suitable for this embodiment is manufactured by Presealed Systems LLC.
- the Pre Sealed Systems mid body seal as a suitable seal may be cast straight into the concrete wali of a reservoir and provides a suitable seal and enough space so a taper may not be required to prevent pipe touching the concrete. However, in this embodiment, the O-ring cannot be removed for maintenance.
- a nail and a screw may not be structural equivalents in that a nail employs a cylindrical surface to secure wooden parts together, whereas a screw employs a helical surface to secure wooden parts together, in the environment of fastening wooden parts, a nail and a screw are equivalent structures.
