Definitions

  • This invention lies in the field of mechanisms for the flushing of a toilet cistern and the mechanism may be adapted for certain other analogous purposes.
  • An object of the invention is to provide a dual flush mechanism which is not prone to leakage.
  • a further object is to provide one which is of robust and simple construction, which will be durable.
  • a further object is to provide one which presents the user with a clear and simple means of effecting a choice between a large flush and a small flush.
  • the solution proposed in accordance with the present invention provides a toilet flushing mechanism for a toilet cistern which comprises an inner upright pipe fixed to the cistern flushing outlet so that the bore of the inner pipe communicates with the flushing outlet, this pipe thus providing an outlet for flushing water at its lower end and comprising two inlets for flushing water at two different heights in the inner pipe, one a lower height and the other a higher height, together with a lower outer pipe or sleeve loosely slidable upwards and downwards on the inner pipe and having a sealing seat at its lower end which can seal on to a flange at the bottom of the inner pipe when the lower sleeve is in its lower most position thereby occluding the lower flushing inlet on the inner pipe but the upper end of the lower sleeve in this position not occluding the upper flushing inlet on the inner pipe, together with a second and upper outer pipe or sleeve again loosely slidable upwards and downwards on the inner
  • the first flushing actuator can be actuated and this will then lift the lower sleeve (and incidentally simultaneously also upper sleeve) and the lifting of the lower sleeve will then allow water from the cistern to enter the lower flushing inlet into the inner pipe and the flush will then continue for a longer period until the water level of the cistern has dropped to the lower flushing inlet on the inner pipe. This will, of course, then be a large flush.
  • the levels of the two flushing apertures in the inner pipe can be determined in order to determine the volume of each of the flushes, in relation to the cistern size.
  • the size of the inlet apertures and the bore of the inner pipe will, of course, determine the rate of flushing and this can be set in accordance with required good practice as mentioned in the introductory parts of this specification.
  • This flushing mechanism then requires only two sealable seats on the concentrically arranged sleeves which are conveniently located in appropriate positions by their loose slidable fit over the inner pipe. These two sealing seats can thus utilise a rubber sealing washer or gasket to seat on to a suitable flange on the base of the inner pipe in the case of the lower sleeve and on to a suitable flange at the top end of the lower sleeve in the case of the upper sleeve.
  • the actuating mechanisms may conveniently comprise two handles fixed on to coaxial shafts, the first handle on an inner shaft for the large flush and the second handle on an outer hollow shaft co-axial with the first for the small flush.
  • Each of these shafts can then have a bell crank or the like with suitable linkages to link into each of the sleeves.
  • the designs also have a basic simplicity which makes them simple to install.
  • the small flush can be actuated by the small handle (e.g. 27 in figure 2) and the large flush by the large handle (e.g. 22 in figure 2) which is a logical and obvious selection for the user. This can obviate any need for marking the handles, providing it is not confusing.
  • the toilet flushing mechanism generally indicated by the numeral 1, comprises an inner upright pipe 2 which is fixed to the cistern of which only the floor 3 is partially shown, by screwing the spigot 4 of the pipe 2 to the flushing outlet of the cistern by means of a nut (not shown) and using a sealing washer 5.
  • the sealing washer 5 bears against an integral flange 6 of the pipe 2.
  • the bore 7 of the inner pipe 2 thus communicates with the flushing outlet 8 of the inner pipe 2 which in turn leads of course to the flushing of the toilet bowl.
  • the inner pipe 2 has two inlets for flushing water at two different heights, an inlet 9 at a lower level and an inlet 10 at a higher level.
  • a lower loosely slidable sleeve 11 is provided so that it can slide upwardly and downwardly on the inner pipe 2, it has a sealing seat at its lower end constituted by a sealing washer 12 provided at a lower flange 13 of the pipe 11. This seal can seal onto the bottom end of the inner pipe.
  • the upper end 14 of the lower sleeve 11 which is constituted by a flange does not occlude the upper flushing inlet 10 of the inner pipe.
  • An upper sleeve 15 is provided also loosely slidable on the inner pipe 2 and having a seal 16 at the lower end of the upper sleeve 15 which is constituted by a flange 17 and which can then seal in the lower most position of the upper sleeve onto the flange 14 of the lower sleeve 11. In this position the upper flushing inlet 10 of the inner pipe 2 becomes occluded.
  • a bracket 18 is provided so that a link 19 can lead to a crank 20 fixed on an outer hollow concentric shaft 21 which is operable by a handle 22. This allows for the lifting of the lower sleeve 11 so as to initiate a large flush.
  • the upper sleeve 15 is provided with a yoke 23 to which a link 24 connects to a crank 25 which is fixed on an inner concentric shaft 26 operable by a handle 27 so as to lift the upper sleeve 15 thereby initiating a small flush.
  • the mechanism is also provided with a bracket 28 on to which an arm 29 is pivoted at the pin 30, the distal end of the arm 29 carrying a float which is lifted when the cistern is full.
  • a bracket 28 on to which an arm 29 is pivoted at the pin 30, the distal end of the arm 29 carrying a float which is lifted when the cistern is full.
  • the inner pipe 2 has three vertically extending ridges, of which one, 40, is visible in figure 6; these ridges ease the sliding of the sleeves on the inner pipe.
  • the lower sleeve 11 which is shown in figure 8, has a ridge 40 of double tapering shape, (see also figure 3), instead of two flanges, to provide a smoother action with the catch 33.
  • Two flanges 41 and 42 are provided to hold between them the rubber seal 12 which is shown in figure 10.
  • the upper sleeve similarly has two flanges 44 and 45 to hold between them the rubber seal 16, which is the same as the seal 12, shown in figure 10.
  • the seats for the rubber seals are the upper edge 46 of a circular wall 47 on the lower sleeve and the upper edge 48 of a circular wall 49 on the spigot 4 of the inner pipe.
