  • APR 9 I974 SHEET 1 OF 2 SHEET 2 BF 2 PATENTEB APR 91574 TOILET SEATS The invention relates to toilet seats. Toilet seats are often unhygienic and can harbor disease and therefore have frequently to be cleaned and preferably sterilised or disinfected, particularly where the seats are used in public places such as termini, places of entertainment, or other venues where large numbers of people use a limited number of toilet seats. The risk of one person infecting a great many others is correspondingly increased.
  • the toilet seat may have an end of an air bleed pipe of drip feed apparatus located inthe back of the seat such that when the seat is lifted the end of the pipe will always be submerged in fluid, so as to prevent flooding of the seat.
  • the spacing between the edges of adjacent holes is not more than one-fourth inch.
  • a toilet seat having a duct therein, holes in the upper surface of theseat in'communication with the duct, means on the back of the seat for retaining a fluid reservoir, and means for controlling a flow of fluid from a reservoir into the duct.
  • FIG. 1 is a diagrammatic plan view of a toilet seat
  • FIG. 2 is a view of a section through the seat taken on the line 2-2 in FIG. 1;
  • FlG. 3 is a view of a section through the seat taken on the line 3-3 in FIG. 1;
  • FIG. 4 is a longitudinal section of a bottle unit.
  • a toilet seat as shown in FIG. 1 of the accompanying drawings shows the distribution of the fluid feed pipe'll and the air bleed pipe 12 in a toilet seat.
  • the air bleed pipe 12 is located on the base of the.
  • seat cavity and an aperture 16 is so dimensioned as to be obturated by a predetermined fluid level in the seat cavity 13.
  • the two pipes 11 and 12 pass through a seat cavity 14' and into a reservoir 15 which is located in the back of the seat so as to provide a gravity or pressure feed thereto.
  • the air bleed pipe 12 extends-to the top of the reservoir and the fluid feed pipe 11 extends into the bottom of the reservoir when the seatis in a horizontal position.
  • the air bleed tube 12 terminates at the back of the seat so that when the seat is raised it is always obturated by the fluid which runs into the back of the seat.
  • the volume and disposition of a space R, at the back of the seat is such that when the correct level of fluid is continued in the seat cavity 13, and the seat is lifted to a substantially vertical position, the fluid will flow into the space R forming a fluid level above that in the reservoir 15 so as to prevent fluid flow therefrom and resultant flooding of the seat caused by successive raising and lowering thereof.
  • the disposable container 23 is adapted to be slid axially into the bore in the seat, the container having a groove 12A in which a tongue on the seat engages to locate the container.
  • a plug 31 is provided to hold the container 23 in the seat.
  • The-plug 31 and the container 23 may be of transparent material so as to provide a visual means for determining the fluid level in the container 23.
  • a transparent window 32 may alternatively be provided in the upper surface of the seat.
  • Perforations or holes in the upper surface of the seat are such that the vapour of thedisinfecting fluid effectively sterilises the entire upper surface of the seat with which 'a user comes into contact.
  • a dam means 27 may be provided.
  • the seat is advantageously made of a plastics material by an injection mouldingprocess.
  • the holes in the surface of the seat may be of any convenient shape for example narrow rectangular slots are veryeffective.
  • the container 13 may contain a pressurised gaseous disinfectant. which would be released into the seat cavity 13 through a valve. This would eliminate the need for having the seat accurately levelled and there would be an additional advantage that there would be no liquidswilling about in the seat thus eliminating the slight risk of temporarily wetting the seat surface.
  • a toilet seat a surface whereon the weight of a person is received, said surface including a number of discrete aperture means to disinfect said surface, and means to disinfect said surface, said last-mentioned means comprising reservoir means for disinfectant, said reservoir means forming an integral part of said seat, and cavity means extending throughout said seat below said surface, said discrete aperture means communicating said surface with said cavity means, feed pipe means and air bleed pipe means entering said reservoir means through a wall thereof, said feed pipe means connecting aninterior region of said reservoir,- means containing disinfectant with said cavity means such that said reservoir means is communicated with said surface, and said bleed pipe means connecting said interior of said reservoir means with atmosphere, said bleed pipe means including an aperture means which is capable of being obturated by disinfectant in said cavity means whereby flow through said feed pipe means is cut off.
  • said cavity means has a portion at the rear of said seat, said portion being of such a size and volume that when the seat is vertical, disinfectant in said portion is disposed at a level higher than disinfectant in said reservoir means, whereby disinfectant is prevented from flowing from said reservoir means along said feed pipe means in said vertical position.
