Definitions

  • the present invention relates to a water-closet with a flushing cistern of the type as defined in the preamble to claim 1.
  • Water-closets or toilets have in most cases a water tank or cistern, which is connected to the actual toilet bowl and serves to accommodate the volume of water needed for flushing.
  • this water cistern has been made of the same kind of porcelain as the toilet bowl itself and has then been screwed to this by means of bolts extending through the bottom of the cistern.
  • a water-filling and flushing system is mounted, and the supply conduit to this also extends through the bottom of the cistern.
  • the water cistern is at the upper end closed with a porcelain cover, through which the operating member of the flushing mechanism or system extends.
  • the porcelain cover is in many cases loosely arranged on the cistern and is held in place by a sleeve nut being passed through a hole in the cover and screwed together with the corresponding threaded pipe of the flushing mechanism or system.
  • This prior-art construction suffers from many drawbacks. For instance, it is often difficult to achieve tightness in the passages through the bottom of the flushing cistern and provide an attractive and permanent joint in the transition between the toilet bowl and the cistern bottom.
  • a further drawback is that maintenance, e.g.
  • the bottom valve face is in turn connected to a filling and flushing system, whose lower end is fixed by means of the same valve face.
  • the inner cistern has outwardly directed flange portions forming shoulders, by which the inner cistern rests against a supporting surface of the toilet bowl.
  • For securing the inner cistern to the toilet bowl use is made of a number of clamping screws which, from the inside of the inner cistern, have been passed through the flange portions of the inner cistern and down into the corresponding hole in the supporting surface of the toilet bowl.
  • a considerable drawback of this known construction thus is that the outer tank may easily, owing to the selected method of securing, be dislodged if the user applies great pressure to the outer cistern, for instance when seating himself and bumping against the outer cistern with his back.
  • the outer cistern is secured to the toilet merely indirectly via the inner tank and the filling and flushing system. Since the inner tank and this system are made of a thin, flexible material, the outer cistern can be dislodged even by minor forces which are directed to the upper part of the outer cistern. Moreover, any maintenance or exchange of the bottom valve and the filling and flushing system is connected with the requirement of screwing off the inner cistern from the toilet bowl, which is an operation that necessitates qualified mechanics.
  • the invention thus relates to a water-closet having a toilet bowl and a flushing fluid cistern attached thereto.
  • This comprises an inner cistern and a casing or outer cistern.
  • the inner cistern rests against the toilet bowl by means of an external flange which also forms a supporting surface for the casing.
  • the inner cistern is secured to the toilet bowl by fastening means which are arranged on the outside of the inner cistern and engage with the flange of the inner cistern.
  • Above and at a distance from the supporting surface there is at least one locking projection extending over the supporting surface.
  • On the outside of the cistern there is at least one turnable fixing hook.
  • the casing has an inwardly directed flange at least at the locking projection or projections and at the fixing hook or hooks and is fixed to said supporting surface by means of these projections and hooks.
  • the inner cistern and the outer cistern are designed in such a manner that the inner cistern has an outwardly directed flange or is connected with a bottom plate, the outer edge of which forms this flange.
  • the flange forms a supporting surface for the lower edge of the outer cistern and can also form a seal between the lower edge of the outer cistern and a supporting surface of the toilet bowl.
  • the inner cistern is attached to the toilet bowl by means of fastening elements which are secured to the outwardly directed flange and therefore are located outside the flushing fluid space of the inner cistern.
  • the inner cistern comprises on the one hand one or more locking projections, under which the corresponding flange of the outer cistern can be inserted, and, on the other hand, at least one turnable locking hook, which is turnably attached on the outside of the inner cistern, preferably on the outwardly directed flange, and the shaft of which is accessible from the outside of the water-closet.
  • the filling and flushing system or flushing device is mounted in the inner cistern and its operating member projects through a hole in the top of the outer cistern.
  • a sleeve nut can be used to stabilise the flushing system or device relative to the outer tank, but when using the invention, it is not necessary for this sleeve nut and the flushing system or device to take up any forces for retaining the outer cistern, since this is held in place by the fastening means arranged at the lower end.
  • the torque at the points of attachment will be much smaller when applying an overturning pressure to the outer cistern as compared with the above-mentioned known construction of the inner and outer cisterns.
  • the invention also confers the advantage that the outer flange of the inner cistern can serve as attachment for the necessary inlet pipe which is to be connected to the water conduit. If desired, when using the invention it is therefore possible to assemble in advance the inner cistern, connection pipe, filling and flushing system, bottom valve and distributing or flushing pipe to a single unit, which in simple motions can be put in place and secured to the toilet bowl. It is particularly advantageous if the flushing pipe is joined to the bottom valve in a fixed and completely sealed fashion and therefore is independent of the fitting problems connected with a flushing pipe that is loosely arranged in the toilet bowl.
  • the outer cistern can be moved down over and be fastened under the locking projection or projections of the inner cistern and then be secured by means of the turnable hook or hooks accessible from the outside, while the flange of the inner cistern serves as a sealing insert between the lower edge of the outer tank and the corresponding supporting surface of the toilet bowl.
  • the drawings illustrate a water-closet having a toilet bowl 10, at the rear end of which there is a pit 11 for receiving a distributing or flushing pipe 12, whose two branches are passed through openings 13 in the pit wall and are connected to flushing nozzles (not shown) inside the rim 14 of the toilet bowl.
  • a seat 15 At the upper edge of the pit 11, there is a seat 15. Inside this seat, there are inwardly directed wall portions 16 having through-holes 17 for fastening means which will be described below.
  • the water-closet also comprises an inner cistern 18, which is made of some suitable plastic material.
  • the bottom 19 of the inner cistern is attached to a cistern or bottom plate 20, which extends outside the bottom 19 to form an outwardly directed circumferential flange 21.
  • this flange may be integrated with the inner cistern.
  • the flange 21 rests against the seat 15 of the toilet bowl.
  • the flange 21 serves as attachment for fastening means 22, which in this case are in the form of expansion bolts, which are accessible from the upper side of the flange and which in the mounted position of the inner cistern extend down through the above-mentioned through-holes 17 to hold the inner cistern hard against the seat 15.
  • the heads of the expansion bolts can abut directly against the flange 21 (not shown in this embodiment), but can also (as is the case in the preferred embodiment as shown) abut indirectly against the flange 21.
  • this is thus formed with a shoulder 38 spaced from the bottom plate 20 and the supporting surface 39 formed thereof.
  • the fastening means 22 engage with this shoulder 38 and the flange 21, which results in the cistern being very strongly secured.
  • the bottom plate can be formed with upwardly directed lugs 40 which prevent the fastening bolts of the fastening means 22 from being inclined.
  • the locking projection or projections 23 and the fixing hook or hooks 24 serve to lock a casing or outer cistern 25 which is slipped onto the inner cistern 21 and the lower edge of which rests against the supporting surface 39 of the flange 21 supported by the seat 15.
  • the casing 25 has at its lower end an inwardly projecting flange 26 at least in the positions straight in front of the holding-down projection or projections 23 and the fixing hook or hooks 24.
  • the mutual distance between the locking projection 23 and the shaft of the opposite fixing hook 24 is so much smaller than the distance between the inwardly directed free edges of the corresponding inwardly directed flanges 26 at the lower edge of the casing 25 that the casing, when being mounted, can be slipped onto the inner cistern, pushed backwards such that the flange 26 on the front of the casing is pushed in between the locking projection 23 and the flange 21 and is then fixed in place by turning the fixing hook 24, which thus engages over the flange 21 (see Fig. 1).
  • the stub shaft of the hook may have a hexagonal hole in its free end face for receiving a hex key wrench.
  • a filling and flushing system or flushing device 27 has been mounted in the inner cistern 18 by an external threaded connecting piece 28 being passed through a hole in the bottom 19 of the cistern and in the flange-forming cistern plate 20, such that the device 27, by an abutment surface 30, comes into abutment against the cistern plate.
  • a sealing ring 30 is suitably inserted between the abutment surface and the cistern bottom 19, a sealing ring 30 is suitably inserted.
  • a sleeve-shaped locking nut 31 is screwed to the downwardly extending portion of the connecting piece 28 and adapted to clamp the flushing device in the cistern and to simultaneously clamp the cistern plate 20 against the cistern bottom 19.
  • the distributing pipe 12 is then attached to the sleeve-shaped locking nut 31, for instance by being snapped over this.
  • the cistern plate 20 can suitably have downwardly projecting stabilising projections 32, which ensure that the two branches of the distributing pipe 12 are oriented in the correct, forwardly directed positions.
  • the cistern 18 has indentations 33 in the positions where the fastening means 22 and the fixing hooks 24 are arranged.
  • the toilet bowl 10 also has indentations 41 in the positions of the fixing hooks 24, which thus become accessible from the outside of the inner cistern, the outwardly directed flange 21 of the inner cistern 18 extending as a roof over this indentation.
  • a connecting pipe 34 with coupling means 35 is also attached to the flange portion 21 of the cistern plate 20 and is extended along one of the indentations 33 to the upper edge of the inner cistern and from there to the flushing device 27.
  • the operating member 36 of the device is extended upwards, such that it extends through a passage in the top of the casing 25.
  • a sleeve nut 37 is in prior-art manner used to stabilise the position of the operating member 36 in the passage.
  • this sleeve nut and the flushing device need not take up any forces for clamping the outer cistern or casing to the toilet bowl, but it is sufficient if the sleeve nut stabilises the position of the flushing device relative to the casing.
  • the invention has been shown in connection with a special type of filling and flushing system.
  • the invention may also be used for all types of filling and flushing systems which are mounted in a flushing fluid tank.
  • a separate bottom plate or flange it is possible in some systems to weld or in some other manner permanently attach the plate or flange to the inner cistern.
  • the invention also makes it possible to design a water cistern, in which the cistern and the flushing system are permanently joined together and completely without passages, which may cause water leakage.
