Description:
"A TOILET SEAT AND LID" THE PRESENT INVENTION relates to a toilet seat and lid.

It is usual for a toilet to be provided with both a seat and a lid. A toilet seat, especially in a toilet that is used by a number of different people, may come into contact with the bare skin of a number of people within a short time. It is often thought that germs or the like maybe passed from person to person via a toilet seat. The bowl of a toilet may be inadequately flushed after use and may remain a source of infection.

The present invention seeks to provide a toilet seat and lid in which the risk of germs being pass from person to person is reduced or obviated.

According to this invention there is provided a toilet seat and toilet lid combination, the combination incorporating a source of disinfectant and means to supply disinfectant from said source to said toilet seat and/or the toilet bowl and means to actuate said means to supply disinfectant from the source to the seat and/or the toilet bowl when the lid is in a predetermined position relative to the seat.

Preferably the source of disinfectant comprises a reservoir for disinfectant formed within the said lid.

Conveniently the source of disinfectant comprises a canister removably connected to said lid.

Advantageously the source of disinfectant is connected to a conduit, said conduit incorporating a dispensing valve adapted to be opened when the seat is in a predetermined position relative to the lid, the conduit extending to at least one opening communicating with a space defined between the seat and the lid when the seat and the lid are adjacent each other.

Preferably the source of disinfectant is connected to a conduit, said conduit incorporating a dispensing valve adapted to be opened when the seat is in a predetermined position relative to the lid, the conduit extending to at least one nozzle located to direct disinfectant to a toilet bowl on which the combination is mounted.

Conveniently the source of disinfectant is connected by the valve and conduit to both at least one opening communicating with a space defined between the seat and the lid, when the seat and the lid are adjacent each other, and at least one nozzle located to direct disinfectant into a toilet bowl on which the combination is mounted.

Conveniently the valve comprises a plunger mounted for movement within a bore, resilient means being provided to bias the plunger to one position in the bore, with part of the plunger projecting beyond the end of the bore, the plunger being movable against the bias provided by said resilient means to an intermediate position in which a passageway defined in the plunger is brought into an alignment with parts of the conduit aligned with the bore to establish communication between the source of disinfectant and the space defined between the seat and lid.

According to another aspect of this invention there is provided a toilet seat and toilet lid combination, the lid being provided with a replaceable canister containing disinfectant fluid, the canister being connected to a conduit incorporating the valve, the valve being adapted to be opened when the seat is in a predetermined position relative to the lid, the conduit extending to at least one of an opening to supply disinfectant from the source to a space between the lid and the seat, and the nozzle to direct disinfectant into a toilet bowl on which the combination is mounted, so that as the lid is opened or closed, disinfectant is provided to the seat and the bowl.

Preferably the conduit extends to said opening and to said nozzle.

In an alternative embodiment the source of disinfectant and the means to actuate the supply of disinfectant comprise a pump-action canister adapted to pump disinfectant into a space defined between the seat and the lid when the seat and lid are adjacent each other.

Conveniently means are provided to actuate the pump action of the pump-action canister in response to movement.

Advantageously a recess is provided in the lid to accommodate the pump-action canister, and wherein a drive member is present within the recess, means being provided to drive the drive member axially of the recess in response to movement of the lid relative to the seat.

Preferably the drive member is adapted to move axially of the recess without rotating relative to the lid, the drive member being provided with a threaded axial bore, a threaded member engaging said threaded bore, the threaded member being adapted to be held in a fixed position such that rotation of the lid causes the drive member to actuate the pump-action canister.

Conveniently the means to supply disinfectant are activated as the lid is being closed.

In order that the invention may be more readily understood, and so that further features thereof may be appreciated, the invention will now be described, by way of example, with reference to the accompanying drawings in which: FIGURE 1 is a front view of part of a toilet and a toilet seat and lid arrangement with the seat and lid elevated, FIGURE 2 is a side view of the toilet seat and lid arrangement of Figure 1 with internal parts shown in phantom, FIGURE 3 is a sectional view of part of the seat and lid of Figures 1 and 2 which illustrates a bore adapted to receive a valve member to form a valve to dispense a disinfectant, FIGURE 4 illustrates a sectional view corresponding to Figure 3 which illustrates the bore and the valve member, showing the valve in an initial closed condition, FIGURE 5 is a sectional view corresponding to Figure 4 which illustrates the valve in an open condition, FIGURE 6 is a sectional view corresponding to Figure 4 which illustrates the valve in a second closed condition, FIGURE 7 is a plan view of the valve of Figures 4 to 6, FIGURE 8 is a view corresponding to Figure 1 which illustrates an alternative embodiment of the toilet seat lid arrangement, FIGURE 9 is a view corresponding to Figure 8 which illustrates an embodiment which is a modification of Figure 8, FIGURE 10 is a sectional view of part of the embodiment of Figure 9, FIGURE 11 is a perspective view of part of a toilet seat and lid which illustrates a further alternative embodiment of the invention, FIGURE 12 is an exploded perspective view of part of the embodiment shown in Figure 11, and FIGURE 13 is an enlarged view, with parts shown in phantom, of the embodiment of Figures 11 and 12.

Referring initially to Figures 1 and 2 the rim of a toilet bowl 1, pivotally supports, in a conventional manner, a toilet seat 2 and toilet lid 3.

The outer periphery of the toilet lid 3 carries a downwardly directed lip 4. The under-surface of the lid has a central oval raised region 5. Defined between the downwardly directed lip and the central raised region 5 is an annular channel 6 in the under-surface of the lid 3. The channel 6 is dimensioned to receive the toilet seat 2. Formed on the base of the channel are a plurality of spaced protrusions 7 which extend into the channel.

A hollow cavity 8 is formed within the raised region 5 formed on the lid 3. The hollow cavity is a reservoir to contain a disinfecting fluid. The disinfecting fluid may be under pressure. The cavity 8 communicates with a first conduit 9 for filling the cavity 8, the conduit 9 leading to the exterior of the lid. A non-return valve 10 is provided at the end of the conduit 9 adjacent the outer surface of the lid. A second conduit 11, in the form of an excess pressure venting conduit, also extends from the cavity 8 to the outer surface of the lid 3 and incorporates a pressure relief valve 12.

At the region of the reservoir 8 within the toilet lid closest to the pivotal mounting a further conduit 13 is provided. The conduit 13 initially extends from the reservoir 8 towards the upper surface of the toilet lid 3. The conduit 13 changes direction at a point which is central to the toilet lid and extends substantially parallel with the upper surface of the toilet lid. The conduit extends for some distance parallel to the upper surface of a toilet lid towards the pivotal mounting to a point at which the conduit is divided into two and forms two arms which extend laterally outwardly parallel with the axis of the pivotal connection of the lid and seat to the toilet bowl. Each arm terminates with a conduit portion which is re-directed towards the under- surface of the toilet lid. The ends of these conduit portions define a pair of outlets 14 which communicate with the annular channel 6 in the toilet lid. The conduit 13 is bisected by a dispensing valve 15. The dispensing valve will be described in further detail hereinafter.

Figure 3 shows part of the toilet seat 2 and toilet lid 3, and in particular r shows the part of the lid 3 where the valve 15 is provided. Part of the conduit 13 within the lid 3 is illustrated. Bisecting the conduit 13 at a point in which it is running parallel to the upper surface of the toilet lid is a substantially cylindrical blind bore 16. The bore extends from a point in the under-surface of the toilet lid towards the upper surface of the toilet lid. The closed end of the bore is substantially filled by a compression spring 17. Two O-rings 18 are provided which are received in respective annular grooves formed in the side wall of the bore on either side of the point at which the bore bisects the conduit 13. The portion 18 of the bore closest to the underside of the toilet seat and adjacent the open end of the bore is provided with two diametrically opposed axially extending slots or grooves 19 formed in the side wall of the bore. The slots or grooves 18 extend from the open end of the bore only part way along the length of the bore.

As can be seen in Figure 4, a substantially cylindrical plunger 20 is located within the bore 16. The plunger has a portion adjacent the lower end thereof which is provided with diametrically opposed projecting ribs 21 which are slidingly received within the slots or grooves 19 as shown. The engagement of the ribs 21 with the slots 19 prevents rotation of the plunger 20 within the bore 16, whilst also limiting the axial extent of the movement of the plunger 20 within the bore 16. The lower end of the plunger has a rounded formation. At a point adjacent the upper end of the plunger, the plunger is provided with a transverse passage 23, which extends across the diameter of the plunger. The part of the plunger 20 that defines the passage 23 is received by the O-rings 18 with a sliding sealing fit.

In the initial condition illustrated in Figure 4, the seat is down and the lid is up. The plunger is positioned in the bore so that the rounded end of the plunger projects beyond the under-surface of the toilet lid. The other end of the plunger is in contact with the compression spring 17. The passage 23 is not positioned between the O-rings, but instead is located at a point spaced axially of the bore 16 from the O-rings 18, towards the open end of the bore 16. In this position the passage 23 is not aligned with the conduit 13, and consequently the valve is closed.

Figure 5 illustrates the valve in an open condition when the toilet lid and toilet seat are being brought together, or are being moved apart. In this condition the rounded end 22 of the plunger is in contact with the toilet seat 2 and the plunger is compressed against the compression spring 17 putting the passage 23 substantially in alignment with the conduit 13. Consequently the valve 15 is open. Disinfecting fluid from the reservoir 8 is able to flow through the conduit 13 in the direction of the arrow 24 and exit via the outlets 14 into the annular channel 6 provided in the toilet lid.

Figure 6 illustrates a final condition of the valve 15. In the final condition the toilet seat and toilet lid are in full contact with one another. The rounded edge of the plunger is pressed inwardly by the toilet seat against the bias of the compression spring 17. The passage 23 is at a point where it is not in alignment with the conduit 13 and consequently the valve is closed. The passage 23 is at a position past the O-ring 18 which is closest to the upper surface of the toilet lid. The ribs 21 of the plunger are pushed up against a seat defined by the ends of the slots 19 of the bore 16. The plunger is thus unable to move any further against the bias provided by the compression spring.

When the toilet seat and lid combination are in use, it is to be appreciated that initially it is necessary to fill the reservoir 8 provided in the toilet lid. To fill the reservoir 8 a pressurised liquid or gas is supplied to the reservoir 8 via the conduit 9. The non-return valve 10 in the conduit 9 works in a similar fashion to that in a cigarette lighter. The conduit 11 and pressure release valve 12 allow any air remaining in the reservoir 8 to escape as the liquid is supplied to the reservoir 8 via the conduit 9.

When the disinfecting apparatus is in use, it is to be appreciated that initially the toilet seat and toilet lid may both be in the lowered position, thus being in contact with one another. When the lid to the toilet seat is lifted to permit use of the toilet, the plunger in the dispensing valve 15, which is initially compressed by the toilet lid, will be permitted to move from a closed position through an open position in which the passage 23 is in alignment with the conduit 13. Some disinfecting fluid is discharged through the outlets 14. The dispensing valve then moves into the closed condition in which the plunger extends past the surface of the toilet lid. Thus some disinfectant fluid is discharged as the toilet lid is opened immediately prior to use of the toilet.

After use of the toilet, when the lid of the toilet is lowered, the toilet seat will come into contact with the upper surface of the plunger 22 and compress the plunger 22 against the compression spring 17. The spring 17 will act as a damper to the movement of the toilet lid, so that the lid will move slowly during the final stage of closing of the lid. The passage 23 will pass a point in which the passage 23 is in alignment with the conduit 13 and disinfecting fluid will be able to pass from the reservoir, through the conduit 13 and the passage 23 to the outlets 14. The fluid will be discharged through the outlets 14 into the channel 6. It is to be appreciated that this dispensation of fluid when the lid is being lowered is more effective than the dispensation of fluid which is provided when the lid is being raised as more disinfecting fluid is discharged than when the lid is opened, and also because the disinfecting fluid is injected into the space between the base of the channel 6 in the lid and the upper surface of the toilet seat 2 just as the toilet seat 2 substantially seals the channel 6. There is a space between the base of the channel and the upper surface of the seat 2, because of the presence of the projections 7. The disinfecting fluid, possibly in a vapour form, will flow through the space between the base of the channel 6 and the seat 2. Thus the entire upper surface of the seat 2 is subjected to the disinfecting fluid.

As the toilet lid is completely closed against the toilet seat the valve 15 will move into its final position with the plunger 20 being completely compressed against the compression spring 17 and the passage 23 moving into a condition where it is not in alignment with the conduit 13.

Figure 8 illustrates an alternative embodiment of the toilet seat and lid combination. The arrangement is similar to that described in Figure 1 and consequently like parts will not be re-described.

In this embodiment a reservoir of disinfecting fluid, which may be a liquid or a gas, is releasably connected to the toilet lid, instead of being integrally formed within the lid.

Provided on the lower surface of the central region of the toilet lid 3 are a number of depending resilient tongues 24. A canister 25, which may be pre- filled with a disinfecting fluid, in the form of a liquid or a gas is clipped into place beneath the lid and is retained, by the resilient tongues 24. One end of the canister 25 is provided with a releasable sealing mechanism 26. The sealing mechanism 26 serves to connect the canisters to the conduit 13 up- stream of the valve 15. The toilet lid may be configured to define a recess in the under-surface of the lid which is dimensioned to accommodate the canister 25. Thus the canister 25 is discretely hidden way. A clip-on cover maybe provided which conceals the canister.

The illustrated embodiment operates in substantially the same way as has been described for the first embodiment. However, the canister, when empty, is removed and is replaced by a new canister.

Referring now to Figures 9 and 10, a further modified embodiment of the invention is described which is similar to that of Figure 8. Like references will be used for like parts which will not be re-described.

The canister 25 of Figure 8 in this embodiment is connected, by means of the valve 15 and the conduit 13, to at least one outlet constituted by a nozzle 27 which is located on the under-side of the lid adjacent the canister 25 so as to direct a jet of disinfectant directly into the toilet bowl.

In this embodiment it is preferred to utilise a liquid disinfectant, and thus, as the toilet seat is lowered, liquid disinfectant is sprayed on to the toilet bowl through the or each nozzle 27. The nozzle or nozzles 27 may be designed and located so that disinfectant is applied to all of the exposed surface of the toilet bowl. As the lid is subsequently raised, in order to ready the toilet for use, more liquid will be dispensed through the nozzle or nozzles 27 so that the toilet bowl is again disinfected immediately prior to use.

It is to be appreciated that in a further modified embodiment of the invention, the valve 15 may serve to connect the reservoir or disinfectant, not only to one or more nozzles 27 adapted to direct this disinfectant into the toilet bowl, but also to the outlets 14 as described in the embodiment illustrated with reference to Figures 1 to 7. Thus the disinfectant may be applied to both the toilet bowl and the toilet seat.

Since it is preferred to utilise a liquid disinfectant for application through the nozzle or nozzles 27 to the toilet bowl, and since it is preferred to utilise a gaseous disinfectant for application to the toilet seat, in a further modified embodiment the replaceable canister may comprise two chambers, one containing disinfectant liquid, the other containing a disinfectant fluid, the two chambers being connected to respective valves of the type described above, one valve serving to connect a chamber containing a disinfectant liquid to one or more nozzles adapted to direct the liquid into the toilet bowl, and the other valve serving to connect a chamber containing gas to outlets such as the outlets 14 adapted to direct the gas to the toilet seat. The canister, containing the two chambers, may be provided as a single integral unit, or may be provided as two sub-units.

Referring now to Figures 11 to 13, a further embodiment of the invention is illustrated. In this embodiment a mounting bracket 30 is provided adapted to be connected to a toilet pan, and a toilet seat 31 and a lid 32 are pivotally supported by the bracket 30. The bracket 30 comprises a planar plate 33 adapted to rest on the top of the toilet bowl, the planar plate defining two apertures 34 (only one of which is shown) each adapted to receive a bolt by means of which the plate is secured to the toilet pan. The planar plate presents two upstanding lugs 35, each of which defines a horizontally extending bore 36 adapted to receive a pivot pin.

The toilet seat 31 is of conventional form and is provided with two rearwardly extending lugs 37 which are dimensioned to be located adjacent the outer faces of the upstanding lugs 35. Each lug 37 is provided with a recess or bore adapted to receive pivot means passing through the said bores 36 in the lugs 35 so that the seat 31 is pivotally connected to the toilet pan.

The lid 32 is also pivotally connected to the toilet pan by means of the lugs 35. The seat 32 is provided with two rearwardly extending lugs 38 adapted to be located adjacent the inner faces of the upstanding lugs 35 provided on the plate 33. The lugs 38 provided on the seat are also provided with means adapted to co-operate with the pivot means passing through the bore 36 of each of the lugs 35.

As will become clear from the following description, the pivot means associated with the lug 35 and the lug 38 shown most clearly in Figure 10, are adapted to actuate a pump dispenser which is contained within the lid 32 of the toilet seat.

As shown most clearly in Figure 12, the upper surface of the toilet seat 32 is recessed between the lugs 38. The recess forms a part cylindrical cavity 40, the axis of the cavity being substantially co-aligned with the axis about which the lid pivots relative to the toilet bowl. At one end of the cavity, adjacent the lug 38, which is shown most clearly in Figure 10, the base of the cavity is provided with a generally cylindrical projection 41, the axis of the cylindrical projection being parallel with the axis of the cavity.

The generally cylindrical recess 40 is dimensioned to accommodate a canister 42 adapted to contain a disinfectant fluid. The canister is provided, at one end, with a cap 43, the cap 43 incorporating an ejection nozzle 44. The canister is such that if the cap 43 is depressed axially of the canister, fluid from within the canister is ejected through the ejection nozzle 44 by means of a pump mechanism contained within the canister. The canister thus comprises a pump dispenser.

The canister is positioned within the part cylindrical recess 40.

Between the cap 43 of the canister 42 and the lug 38 shown most clearly in Figure 10, a drive member 45 is positioned. The drive member 45 is of a generally disc-shape, with a part cylindrical cut-out 46 formed in the periphery thereof dimensioned to receive the cylindrical projection 41 formed in the base of the recess 40. The drive member 45 is provided with an axial threaded bore 47. The drive member 45 is located inn a vertical position with cut-out 46 engaging the cylindrical projection 41.

A pivot pin 48 is illustrated. The pivot pin has a first cylindrical end 49 which is adapted to engage in an appropriate recess or bore formed in a lug 37, formed on the toilet seat 31. The pivot pin has an intermediate portion 50 dimensioned to be received as a friction fit within the bore 36 formed in the upstanding lug 35. Thus the pivot pin itself is prevented from rotating. The pivot pin 48 then has a further cylindrical portion 51 which is adapted to be received in a bore 52 provided in the lug 38 which is illustrated most clearly in Figure 12, to enable the toilet lid to rotate about the pivot pin 48. The pivot pin 48 terminates with a threaded portion 52 adapted to be received within the threaded bore 47 provided in the drive member 45.

The recess 40 forms the rear part of a generally semi-circular recess 53 of uniform depth defined in the upper surface of the toilet seat 32. The semi- circular recess 53 has its diametric portion extending between the lugs 38. A cover 54 for the recess 40 is provided, the cover being of semi-circular form, and thus having a configuration to correspond with the configuration of the recess 53. The cover is provided with a depending side wall 55 which presents, towards the diametric portion of the cover 54, two depending lugs 56,57. The lugs 56,57 are dimensioned to be located adjacent the inner faces of the lugs 38 provided on the toilet lid 32. The inner face of one lug 38 is provided with a recess 58 adapted to be engaged by a projection 59 of corresponding form provided on the outer face of the adjacent lug 56 carried by the cover 54.

The other lug 57 of the cover 54 is provided with a U-shaped slot or recess 60 having a width substantially equal to the width of the portion 51 of the pivot pin 48.

It is to be appreciated that before the canister 42 is located in position within the recess 40, the cover 54 may be mounted in position by engaging the projection 59 on the lug 56 provided on the cover 54, with the recess 58 provided on the lug 38 of the lid 32, and moving the lug 57 so that the slot 60 formed in the lug 57 embraces the portion 51 of the pivot pin 50. The canister 40 may then be located in position with the cap 43 being located adjacent the drive member 45. The cover 54 may then be moved pivotally to a position in which the cover 54 substantially closes the recess 53, thus concealing the canister.

As can be seen more clearly from Figure 11, the recess 40 defines a protrusion on the underside of the lid 32 located between the lugs 35 carried by the mounting plate 30. An aperture 61 is formed in the wall that forms the recess 40, that aperture being co-aligned with the ejection nozzle 44 of the canister 42.

It is to be appreciated that as the toilet lid 32 is rotated relative to the support plate 30, the drive member 45 will be constrained to rotate with the lid because of the engagement of the recess 46 formed in the periphery of the drive member 45, and the cylindrical projection 41 formed in the basis of the recess 40. As the drive member 45 rotates, because of the screw-threaded engagement of the screw-threaded bore 47 and the screw-threaded terminal portion 52 of the pivot means 48, the drive member 45 will be driven axially within the recess 40.

The arrangement is such that, as the lid 32 is closed, thus bringing the lid 32 adjacent the toilet seat 31, the drive member 47 is driven axially of the recess 42 engage the cap 43 provided on the canister 42 causing the dispensation of some fluid from within the canister 42 through the ejection nozzle 44 of the canister and through the aligned aperture 61 formed in the wall defining the recess 40. The fluid is thus injected into the space between the lid 32 and the seat 31. The upper surface of the seat 31 is thus subjected to the disinfecting fluid from the canister 42.
