Definitions

  • the field of this invention concerns an automatic device for preventing animals coming up into drain pipes, and in particular into toilet bowls.
  • lever mechanisms can, over time, get worn making it impossible for the WC to continue working normally; therefore, they need to be continually serviced.
  • said devices can be used only in the pipes for discharging wastewater and they adapt, badly or not at all, to other types of discharges, which also suffer from the same problem of animals coming up into the discharge outlets.
  • the object of this invention is to overcome one or more of the drawbacks of the prior art.
  • Another object of this invention is to make available a completely automatic device to guard against animals coming up through WC drain pipes.
  • Another object of this invention is to make available a completely mechanical device to guard against animals coming up through drain pipes.
  • Another object of this invention is to make available a device to guard against animals coming up through drain pipes that can also be installed outside the pipes.
  • An important object of this invention is to make available a device to guard against animals coming up through drain pipes that is easy to construct and easy to operate.
  • a fundamental object of this invention is to make available a device to guard against animals coming up through drain pipes that is reliable also in the long term.
  • a further object of this invention is to make available a device to guard against animals coming up through drain pipes that works safely.
  • the automatic device for preventing animals coming into drainage pipes includes, between the drainage pipe of a facility connected to the hydraulic drainage system for waste water, a mobile divider in the water pipe, with automatic return, hinged at the top and swinging, being able to tilt in the direction of the outflow, i.e. capable under the thrust of the discharge water to tilt partially without excessive contrast, freeing the pipe section for the outflow of the water, and returning under the action of its own weight to assume a rest position closing practically all the section, to prevent animals coming up into the bowl.
  • the object of the invention can be configured as a completely mechanical device.
  • the movement for the operation of said mobile divider is automatic, not requiring any external instigation to intervene with respect to the flow of water.
  • the closure made by the mobile divider on the stop is carried out by maintaining a light positive closing force (which can be given by the inclination that is slightly offset with respect to the vertical).
  • said device requires no maintenance because of the way it is made and as a result, it can be used in all circumstances since it can also be used in places that are not easily reached.
  • the advantage of the mobile divider lies in the fact that it is not connected to any kinematic or lever mechanisms, also external.
  • said divider is flat and level, preferably with a smooth surface (facilitating the self-cleaning).
  • Another advantage of the mobile divider of the invention lies in the fact that it does not obstruct the outflow section, since it can tilt, without inserting any appreciable overpressure in the outflow and having practically a negligible effect on the outflow itself.
  • said mobile divider can be inserted and become part of the toilet bowl, near to, or inserted in, the relative syphon of the discharge pipe.
  • the toilet bowl 1 has a seat 2 for the user, with a tapered zone 3 connected hydraulically with a siphon 4.
  • the siphon is usually adopted to prevent the outflow pipe 5 freely discharging the vapours of the waste water pipes to which the outflow pipe is connected with the room in which the toilet is installed.
  • the device of the invention is installed in a toilet bowl 7 that has been prepared for it, or else on a toilet bowl of the prior art that has been appropriately modified.
  • Said divider 11 is mobile, it is held up at the top in a tilting manner by a hinge 13 with a horizontal axis, which allows said divider to swing, with a movement of partial rotation in the direction of the flow of the water, and under the pressure of this water when released from the flushing system to then take up its basically vertical rest position due to the effect of its own weight.
  • This movement then, is completely automatic and does not require either the opening of the discharge section or any action to close it with any kinematic or lever mechanisms operated externally.
  • said divider 11 is subject to natural forces, like the pressure of the water flow to open it, and the force of gravity to close it, it is extremely reliable and does not need any maintenance or work to deal with wear and tear.
  • the limitation of the travel of the opening movement of the divider 11 can be realised by the inner surface of the pipe.
  • the limitation of the travel of the closing movement of the divider 11 is composed of one or more stop bushings or by one or more protrusions 14 that stick out slightly from the surface of the pipe, and therefore have no influence on the re-sectioning of the free section of the outflow.
  • said pre-charge is obtained by keeping the divider 11 slightly inclined, offsetting the hinging point 13 with respect to the stop bushes or protrusions 14.
  • this device Since this device is extremely reliable and requires no maintenance, it can also be recessed or hidden so it cannot be seen, allowing the toilet bowl to look the way it looks in the prior art. Lastly, it should be noted that the presence of this divider 11, while closing completely and being an insurmountable and impossible obstruction for the animals 15 that live in the sewerage networks to get through, does not insert any sizeable element for restricting the free section of the outflow section.
