Definitions

  • the present invention relates to a toilet and a closure device which automatically closes the toilet outlet when the toilet is not in use.
  • the present invention is particularly directed towards a device for use with a septic system or pit toilet.
  • sewage may be treated in septic tanks or pits.
  • Septic tanks and pits are typically watertight chambers in which bacterial decomposition of the sewage sludge takes place.
  • Inlet and outlet vents are generally provided to allow a flow of air through the tank or pit.
  • the vents are typically covered with a fly proof mesh to prevent flies from entering the tank or pit.
  • the bacterial decomposition generates unpleasant odors.
  • the inlet and outlet vents are located external to the room. It is therefore important that the inlet and outlet vents are the only openings into the tank or pit.
  • the water in the toilet bowl provides an effective seal for the septic tank.
  • odor and fly control of the septic tank is normally not a problem in these systems .
  • toilets do not have a water seal and are sometimes referred to as "dry" toilets.
  • Such toilets are normally used in arid or remote areas where there is an unreliable water supply.
  • toilets of this type have a bowl which opens directly into the septic tank or pit. It is therefore important for odor and fly control that the toilet lid remains closed when the toilet is not in use. This relies upon a person to reclose the lid immediately after use.
  • people often .neglect to close the lid and the present inventor has observed that this is particularly so in some communities who are unfamiliar with the operation of dry toilets. Extended exposure of the septic tank or pit contents to the atmosphere within the toilet room may also occur if the toilet lids and seats are broken and/or removed by vandals.
  • Toilets having means for closing an outlet are known. Such known closure devices may be vacuum operated or operated by compressed air. These mechanisms require a power source. Power operated closure devices are not viable in isolated areas where no power is available. Also, these toilets require manual operation such as pulling a lever, pressing a button or are operated in response to raising and lifting of the toilet lid. It can be seen that these types of devices also suffer from the disadvantage that some degree of manual intervention is required. Further disadvantages of the known devices are that they are typically complicated to manufacture and operate and have a number of parts which require servicing and maintenance. They are therefore unsuitable for use in remote areas where regular servicing is not possible.
  • a device for closing an outlet of a toilet including a sliding member which is slidable between a closed and an open position and which is biased towards the closed position, an actuating means for sliding the sliding member between the closed and open positions and which is adapted to be actuated by the weight of a user, such that when the toilet is in use, the actuator slides the slide member to the open position and when the toilet is not in use, the slide member is returned to and maintained in the closed position.
  • the device of the present invention may be used with any type of "dry" toilet having an outlet.
  • Such toilets include conventional toilets having a ceramic bowl, wooden bench type toilets, portable toilets or toilets for use in moving vehicles.
  • the actuating means may be any suitable type of actuator which is operated by the weight of a user.
  • the actuating means may include an arm and lever which is located such that it abuts the lower surface of a toilet seat. When a user sits on the seat, the arm or lever is depressed which actuates the sliding member to open. This can be accomplished by a suitable lever arrangement.
  • the actuating means may include a pressure actuator located beneath the seat . The pressure actuator in turn controls a hydraulic or pneumatic ram which operates to move the sliding member to the open position. When the pressure is released, the rams return the sliding member to the closed position.
  • the sliding member of the toilet of the present invention may be of any suitable type.
  • the sliding member In the closed position, the sliding member should substantially restrict the entry of flies into and odor from the septic tank or pit. It is not necessary that an airtight seal be provided, although a substantially airtight seal is preferred.
  • the device has a pair of opposing semicircular slide members which slide away from and to each other so as to open and close the opening.
  • the device is housed in a frame having an upper portion movable between an upper and a lower position relative to the frame. The upper frame portion is biased towards the upper position.
  • the actuating means is operatively associated with the frame member and the lower part of the toilet pan is adapted to rest on the frame member.
  • a device for closing an outlet of a toilet having a frame, a frame member movable between an upper and a lower position in response to weight being placed on a toilet pan, biasing means for biasing the frame member in the upper position and a closure means movable between a closed and an open position when the frame member is depressed and a closed position.
  • the device further includes an additional actuating means adapted to locate on the floor or ground directly in front of the toilet.
  • the closure may also be activated to open when a user is standing in front of the toilet bowl.
  • Figure 2 is a schematic side view of the toilet of Figure 1 in the open position and Figure 3 is a plan view of the toilet of Figure 1.
  • Figure 1 illustrates a device 11 having a frame 12.
  • a pan 10 of a toilet rests on frame 12 and the frame is supported by legs 9.
  • An outlet conduit 13 is housed within the f ame 12. Sewage passes into the tank or pit through conduit 13.
  • a pair of semicircular slide members 14, 15 are located in conduit 13 and are illustrated in the closed position. The slide members are slidable between open and closed positions and pass through slots 16, 17 located on conduit 13.
  • a drip tray 18 extends about conduit 13 and below slide members 16, 17.
  • the frame 12 has a rectangular upper frame member 20.
  • the frame member is movable between upper and lower positions in response to weight placed on pan 10.
  • the frame member 20 is biased in the upper position by springs 21.
  • any type of resilient material may be used to bias the position of the upper frame member 20 " such as a portion of an elastomeric plastic material such as rubber.
  • a vertical rod 22 is attached at its upper end to the upper frame member 20.
  • Rod 22 is pivotally attached at its lower end to one end 23, 24 of a pair of arm members 25, 26.
  • Each arm member 25, 26 has a further arm 27, 28 extending normal thereto. To these arms 27, 27 are pivotally attached opposing ends of a pneumatic cylinder 29.
  • the lower ends 30, 31 of the arm members 25, 26 have an elongate aperture 32, 33 located therein. Through each aperture 32, 33 extends a linkage 34, 35 which is attached at one end to a respective slide member 14, 15.
  • the opposing side of the device has identical features.
  • Figure 3 is a plan view of the device of figure 1.
  • the slide members are illustrated in the closed 14a, 15a position and in the open 14b, 15b position.
  • the rod 22 may extend further along the toilet pan and abut the lower face of a toilet seat.
  • Weight on the seat actuates the device in the manner as described above.
  • An advantage of having the device in a frame beneath the pan as illustrated in the Figures, is that the whole device may be enclosed and cannot be tampered with or vandalized. Further, the device will also function if the seat has been removed or damaged.
  • the device may also be operated by a foot pedal, not illustrated.
  • the pedal may be pivotally connected at one end to the floor.
  • a spring or other biasing means may be located at the other end of the pedal so as to lift the pedal slightly above floor level.
  • the pedal is attached via a lever to rod 22. In use, when the pedal is depressed the slide members are caused to open in the manner as described above. When not in use, the spring returns the pedal and slide members to the closed position.
  • the springs or other biasing means as used in the present invention are preferably selected so that the device will only be actuated to open when the weight on the pan, toilet seat or pedal exceeds about 9kg.
  • This weight corresponds to the average weight of a child who is beginning to use a toilet.
  • the seal cannot be activated during cleaning of the toilet or by smaller children who may be crawling on the toilet. It can be seen that this provides an additional advantage in that objects which may be inadvertently dropped in the toilet will be caught by the slide members and will not fall into the septic tank or pit.
  • the foot pedal may also be connected to a water cistern.
  • Water nozzles may be located on opposing edges of the inner surface of the upper part of the bowl. When the pedal is activated, any water in the cistern may be released to wash out the bowl. It will be appreciated that in arid areas, fresh water may not always be available for washing the bowl. In these circumstances the water cisterns may be adapted to collect gray water.
  • the device of the present invention effectively seals a septic tank or pit irrespective of the position of the toilet lid.
  • the device automatically opens when the toilet is being used and subsequently closes when the toilet ceases to be used.
  • the device also does " not rely on external power sources such as compressed air, solar power or mains electricity.
  • the device has a minimal number of moving parts and is particularly suited for installation in remote areas where regular servicing or maintenance is not possible. Finally, the outlet is closed automatically and no manual control is required.
  • the device may also be fully enclosed and no moving parts are exposed. This means that the device may at least partially protected from vandalism. Further, the device does not require the presence of a toilet seat for operation.
