  • the pin 17 rests in a branch 19 of the guide rail 18 whereas the pin 17" rests in the vertical portion of guide rail 18.
  • the two pins 17' define an axis about which the closet seat ring 11 can be turned up.
  • the pins 17 and 17" are preferably rotatably mounted in the seat ring 11 so as to reduce the friction occuring when they are moved along the guide rail.
  • the cover 13 For cleaning the closet seat ring 11 after use of the closet, the cover 13 is first opened by means of handle 14. Cover 13 is held in its open position by a stop means or a retaining means. Then the closet seat ring 11 is turned up about the axis defined by pins 17' by means of handle 12, until pins 17" are lowered to the point where branch 19 bifurcates from the vertical portion of guide rail 18. Thereafter the seat ring 11 is pushed downwards until all four pins are in the vertical portion of guide rails 18. The seat ring 11 can then be released so that it falls into the cleaning box 15 under gravity action; If desired, it is also possible, of course, to guide seat ring 11 by holding handle 12 until the lowermost position is reached.
  • the rear end surface of seat ring 11 may preferably be provided with a cushioning strip of rubber or the like for reducing the shock on impact,
  • a triggering device could in turn be actuated for example by a means detecting when the weight of a user is removed from the seat ring after use, or by the operation of a flushing handle or knob for flushing closet bowl 10 in usual manner.
  • the closet seat ring 11 in cleaning box 15 is held' in a vertical position by the four guide pins which are located at positions indicated by reference numerals 20 and 21. Additional clamping devices may be provided for retaining the pins in these positions.
  • FIG. 4 diagrammatically depicts an optional device for pulling the closet'seat 11 into the cleaning box 15.
  • a pulling cable 22 is attached to the lowermost end of seat ring 11. Cable 22 runsover two rollers 23 and is tensioned by a helical spring 24. The seat ring 11, when it has been released, is automatically pulled into its end position by spring 24.
  • cover 13 Before the starting of-a cleaning operation cover 13 is closed manually or automatically. Cover 13 then contacts the upper end of the cleaning box via a sealing strip 9 of rubber or the like for forming a water tight closure.
  • Automatic closing of cover 13 may be brought about, for example, by a linkage operated by closet seat ring 11, when this reaches its lowermost position in cleaning box 15, for releasing a cover retaining device so that cover 13 drops into closed position.
  • cover a resilient hook 25 (FIGS. 5 and ,6) which slides over the nose of seat ring 11 and engages therebelow when cover 13 closes.
  • the turbine 30 When seat ringll is in its lowermost the turbine 30 may then be drivenin the reverse direction so that the rubber flaps are pressed against theseat ring 1'1 for wiping the water off it.
  • Drying of the seat ring 11 may be enhanced by adding to the water during the last phases of washing a drying agent, for example in the form of an alcohol.
  • a drying agent for example in the form of an alcohol.
  • the water adhering to the seat ringll could also be removed or shaken off by vibrating the seat ring. Drying can be accelerated and/or supplemented, if desired, by the application of radiant heat.
  • one or more annular heating elements may be provided in cleaning box 15.
  • cover 13 is pulled down by hook so that rubber strip 9 resting on the rim of cleaning box 15 forms the desired tight closure.
  • the closet seat ring 11 falling into its lowermost end position can' also, if desired, actuate aswitch 26 (FIG. 5) for starting a closet bowl flushing operation, or for causing cover 13 to close and initiating the cleaning of the seating surface as described hereinafter and at the same time starting the flushing of the closet bowl. This cleaning and flushing can then beterminated automatically after a predetermined time.
  • the rear wallof the cleaning box 15 is disposed so as to leave ample room'for a cleaning device.
  • tap water from an annular distributing line 27 is sprayed onto the closet seat ring 11 by way of suitable nozzles. It is possible, if desired, to first heat the water externally of the cleaning'box by means of a heat ing device, or to take the water from a warm water conduit. Also, a detergent may be added to the water by appropriate means. The water leaves cleaning box 15 by way of a conduit 27a, for reasons of economy it can then additionally be used for flushing the closet bowl. After the cleaning described above the closet seat 11 is disinfected. This may be achieved for example by adding a disinfectant medium to the water which is sprayed onto the seat.
  • FIG. 7 shows a modified device for cleaning the closet seat ring'by spraying water or other cleaning liquid onto it.
  • the water emerges from tubular arms 28 having suitable nozzles.
  • the arms 28 are rotatably mounted on the rear wall of the cleaning box 15, they. are rotated by the reaction force of the water jets leaving the nozzles, in a manner which is known in lawn sprinklers.
  • the cleaning effect may be enhanced by providing the ends of arms 28 with brushes 29.
  • the arms 28 may also be rotated by means of a turbine 30. In this case water flows through the turbine and at the same time through the arms 28 and through openings therein provided within the brushes 29. Similar constructions are known in devices for washing automobiles.
  • the turbine 30 may continue to rotate the arm 28'after the flow of water therefrom has stopped, so that the brushes 29 then wipe the water from the closet seat ring 11. It is also possible to mount two rubber flaps behind the brushes. After washing,
  • aspring could be provided which is compressed by the seat ring 11 falling into its lowermost position, and which is locked in the, compressed state. This spring may then be released after cleaning for automatically raising the seat ring 11 somewhat. Finally a pulling cable and/or a motor could be used for raising the seat ring 11.
  • the closet seat ring 1 1 may be cleaned in a most simple and inexpensive way if all the above described operations are'carried out by hand. However, partly or fully sophisticated embodiment, all operations may be controlled and effected automatically by a programmed control unit and corresponding motors and drive arrangements. It is obvious that such a solution would be relatively'expensive and require a comparatively large space.
  • FIGS. 9 to 13 illustrate an embodiment of the invention in which the cleaning box is-disposed laterally of the closet bowl.
  • This arrangement may be advantageous for the following reasons. Since the closet seat is turned about an axis parallel to its longitudinal extension, the height of the cleaning box must only be sufficient to receive the width of the closet seat. The height of the cleaning box can therefore be smaller than in the arrangement according to FIGS. 1 to 8. In existing toilets, where there is little free space behind the closet bowl, it is generally possible without difficulty to arrange a cleaning apparatus having a cleaning box laterally of the closet bowl.
  • FIG. 9 shows a diagrammatic plan view of a closet arrangement in its position immediately before or after use.
  • a closet seat ring 31 which rests on a closet bowl (not visible in the drawing) is provided with a handle 32 on one side and with two lateral arms 33 on its other side.
  • Each arm 33 carries on its end a sliding element in the form of a ball 34 which is disposed in a partly cut out hollow shaft 35.
  • This shaft 35 extends horizontally through two vertical guide rails 36 in a cleaning box 37 which is shown without its cover in FIG. 9.
  • a toothed wheel 38 is mounted on an end of shaft 35 outside cleaning box 37.
  • a hydraulic cylinder 43 (FIG. 13) is first actuated by the operation of a usual closet flushing device.
  • cylinder-43 turns hollow shaft 35 through 90.
  • This shaft which is cut out within guide rails 36 as shown in FIG. 11, its wall extending below arms 33, raises'these arms and also turns them through 90 so that seat ring 31 is turned into a vertical position.
  • Arms 33 are bent as shown in FIG. 10, and therefore the seat ring 11 in its vertical position is disposed laterally of the guide rails 36, the arms 33 extending through slots 39 in the guide rails. Under the action of gravity the turned-up seat ring 31 falls vertically down into cleaning box 37 adjacent to guide rails 36.
  • seat ring 31 actuates a lever 40 which closes cover 42 of cleaning box 37 by means of a linkage 41 (FIG. 12).
  • a helical spring 42a is disposed in cleaning box 37 so as to be compressed by the seat ring 31 reaching its lowermost position, a latch (not shown) being actuated at the same time for retaining seat ring 31 in this end position.
  • the operation of this latch is detected by an electric switch which then starts an electronic program control unit for automatically effecting the cleaning (for example washing and drying) of seat ring 31.
  • a casing could of course be provided for covering toothed'segment 46 and the drive means therefor.
  • These drive means could comprise a motor, for example an electric motor, in place of cylinder 43 and plunger 44.
  • a motor could be started by any suitable means, for example by the actuation of the closet flushing device as described, or by means of a switch that may be operated manually or automatically as soon as a user leaves the closet seat and thereby discharges it. Such a switch might then in turn automatically actuate the closet flushing device.
  • the actual cleaning operation in cleaning box 37 can be carried out in the manner already described, by means of cold and/or warm water which is sprayed from nozzles, and if desired with the aid of rotating brushes. Disinfecting and drying agents may be added to the water. Air and/or radiant heat may be used for drying the closet seat ring.
  • an electric motor for opening and closing the hinged cover of the cleaning box.
  • the seat ring preferably is disposed in the cleaning box when the closet is not in use.
  • the seat ring in its cleaning position rests on a vertically movable support member in the form of a horizontal bar which is guided in the cleaning box and whose two ends are connected to the cleaning box cover by connecting elements in the form of cables or chains, for example.
  • a person who wants to use the closet pushes a button for starting the electric motor which then opens the cleaning box cover.
  • the cables or chains attached to the cover act to raise somewhat the said bar and the seat ring resting thereon. From this raised position the'seat ring may then conveniently be gripped by hand and moved into the position of use on the closet bowl.
  • a switch is actuated, for instance by one of the arms carrying the seat ring, for starting the electric motor in the reverse direction to close the cleaning box cover again.
  • the electric motor is again switched on for opening the cleaning box cover.
  • the hydraulic cylinder 43 then turns the closet seat ring up in the manner described, and from the swung-up position the seat ring drops into the cleaning position under the action of gravity, thereby pushing the aforesaid bar into its lowennost position.
  • the cables or chains connected to this bar pull the cleaning box cover down to close it. After the cleaning, the seat ring remains in the cleaning position with the cleaning box cover closed.
  • FIGS. 14 to 16 illustrate a further closet arrangement with a cleaning box disposed behind the closet bowl and in which the seat ring is moved into and out of the cleaning box by mechanical means.
  • the drive is derived from a pivotable closet bowl cover 51.
  • a pulley 52 attached to cover 51 is connected by means of a belt 53 to a further pulley 54 so that the latter turns as cover 51 is swung up or down.
  • Pulley 54 drives, by means of a toothed segment 66 attached to it, a toothed wheel 55.
  • a link 56 is fixed to the toothed wheel 55 and is pivotable together with the same.
  • the free or outer end of link 56' is connected to the forward end portion of a closet seat ring 58 by means of a hinge joint 57.
  • the rear end of seat ring 58 is provided on either side with a guide pin 59 projecting into a respective guide rail 60 for guiding the seat ring.
  • cover 51 After use of the closet the cover 51 is in its swung-up position as shown in FIG. 15, and the cleaning box 62 is closed by a flap 61 which is urged into its closed position by a spring 63. Cover 51 is now swung down onto the closet bowl by means of a handle 64. During this movement of cover 51 a closet flushing device is actu ated (by means not shown), and belt 53 is driven in the direction of the arrow in FIG. 14. Belt 53 and pulleys 52 and 54 may be provided with teeth or other suitable surface formations to prevent slipping. Toothed segment 66 which is provided on a portion of the circumference of pulley 54 now turns toothed wheel 55 together with link 56. Seat ring 58 is thereby raised and moved into the cleaning box.
  • guide rails 60 The shape of guide rails 60 is chosen so that seat ring 58 is securely guided into its cleaning position in cleaning box 62.
  • the guide rails 60 start on both sides of seat ring 58 from a position adjacent the rear end of the position of use of the seat ring, and they extend into the cleaning box 62.
  • These guide rails 60 and the wheels 52, 54 and 55 togetherwith belt 53 are so designed relatively to each other that seat ring 58 reaches its cleaning position after a 40 rotation of cover 51. When cover 51 has been swung down by 40, the last tooth of segment 66 disengages from toothed wheel 55 so that the latter is no longer driven.
  • Seat ring 58 is retained in its cleaning position (FIG. 16) by a weight 67 adjustably mounted on link 56. On reaching this cleaning position, seat ring 58 actuates a switch 68 for starting the actual cleaning operations which may be controlled and effected in the manner already described. After the above mentioned initial turning of 40 cover 51 can be completely closed down onto the closet bowl (FIG. 16) without obstruction by seat ring 5,8. in this closed position cover 51 covers the closet bowl and at the same time closes cleaning box 62.
  • cover 51 On completion of the cleaning operations, or before the next use, cover 51 is raised, and during this raising the above described movements take place in reverse directions, bringing seat ring 58 out of cleaning box 62 into the position of use.
  • Weight 67 also serves to retain the seat ring in its position of use on the closet bowl.
  • An arrangement for automatically cleaning a closet seating surface on a closet seat ring after use comprising:
  • a cleaning box mounted adjacent to and substantially on the same level as a closet bowl and adapted to receive said seat ring;
