Description
- The present application is a divisional application of co-pending application Ser. No. 10/852,558, filed in the U.S. Patent and Trademark Office on May 24, 2004, entitled “TOILET FLUSHING ARRANGEMENT”, which claims priority from United Kingdom Application Serial No.: 0312014.4 filed in the United Kingdom on May 24, 2003. This divisional application claims priority to the aforementioned patents applications which are incorporated herein by reference for all purposes in their entireties.
- This invention concerns a toilet flushing arrangement, and also a toilet flushing system incorporating such an arrangement.
- With conventional flushing toilets, a significant amount of water is used with each flush which after certain uses is not wholly required and is thus wasteful of water. Dual flushing arrangements are available providing for low volume and high volume flushes, but these are generally of relatively complex configuration. Furthermore, such arrangements usually cannot be retrofitted, and therefore if dual flushing is required, new flushing systems are needed for each toilet at a location.
- According to the present invention there is provided a toilet flushing arrangement, the arrangement comprising an open topped sleeve locatable in a toilet cistern to surround the flush outlet and to extend to a required height in the cistern, with a selectively openable opening provided in a lower part of the sleeve, such that the arrangement provides two flushing modes: a low volume flush with the opening closed, wherein substantially only the water within the sleeve plus the volume of any water located above the top of the sleeve, is flushed; and a high volume flush with the opening open, wherein substantially the volume of the water in the cistern, whether or not in the sleeve, above the lowest part of the opening, is flushed.
- A closure may be provided, selectively locatable over the opening to close same. The closure may be spring urged to a closed position. The closure may be located on the outside of the sleeve, and may be pivotally mounted thereto.
- A control arrangement may be provided such that a first operation thereof causes a low volume flush, and a second operation thereof causes a high volume flush.
- The control arrangement may be provided with a pivotally movable handle, such that a first pivotal movement thereof causes a low volume flush, and a further pivotal movement in the same direction causes a high volume flush.
- The control arrangement may be configured such that after a first pivotal movement of the handle the spring urging of the closure can be felt and must be overcome to cause a high volume flush.
- The control arrangement may include a cam arrangement enagagable with a control mechanism for the flush valve, such that pivotal movement of the control mechanism causes pivotal movement of the cam arrangement.
- The sleeve may have a base, and a hole may be provided therein, or can be formed therein, to locate around the flush outlet.
- The sleeve may have markings and/or areas of weakness provided at an upper part thereof to permit the sleeve to be formed to a required height.
- Alternatively, or in addition selectively removable openings or cut-outs may be provided in an upper part of the sleeve to allow the effective height of the sleeve to be selected.
- As a further possibility, the sleeve could include a further sleeve part mounted in a telescopic manner thereto, and the effective height of the sleeve can be adjusted by telescopic movement of the further sleeve part.
- The sleeve may be formed with areas or lines of weakness on each side thereof to permit the opening to be provided on a respective required side of the sleeve for either left handed or right handed operation.
- The sleeve and flush valve may be formed as a single unit. Alternatively, the sleeve may be fitted around an existing flush valve.
- The invention also provides a toilet flushing system, the system comprising a cistern, a flush valve, control apparatus for the flush valve, and a toilet flushing arrangement according to any of the preceding twelve paragraphs operably located in the system.
- Embodiments of the present invention will now be described by way of example only and with reference to the accompanying drawings, in which:
-
FIG. 1 is a diagrammatic cutaway view of a conventional toilet flushing system; -
FIG. 2 is a similar view toFIG. 1 but incorporating a first toilet flushing arrangement according to the invention; -
FIG. 3 is a diagrammatic perspective view of part of the system ofFIG. 2 ; -
FIG. 4 is a diagrammatic plan view of part of the system ofFIG. 2 ; -
FIG. 5 is a diagrammatical cross-sectional view through part of the system ofFIG. 2 ; -
FIG. 6 is a diagrammatic front view of the system ofFIG. 2 ; -
FIGS. 7, 8 and 9 are diagrammatic perspective views of components of a control arrangement of the system ofFIG. 2 ; -
FIG. 10 is a diagrammatic perspective view of part of a second system according to the invention; -
FIG. 11 is a similar view toFIG. 10 of part of a third system according to the invention, andFIGS. 12 and 13 are diagrammatic side views of further parts of the third system. -
FIG. 1 shows a conventional toilet flushing system 10 with aflush valve 12 operated by alever 14 which causes pivotal movement of abar 16 which connects to thevalve 12 by alink 18. In use thecistern 20 in which the system 10 is located automatically fills through arefill tube 22 to a required height. This required height can be adjusted using theknob 24. Filling takes place into anoverflow pipe 26 which can receive water in the event that excess water is supplied into thecistern 20. - To flush the system 10, the
lever 14 is pushed downwardly causing pivotal movement about itsmounting 28. This raises thebar 16 and hence link 18 and causes theflush valve 12 to operate. Following flushing, theflush valve 12 will automatically reclose and thecistern 20 will be refilled through thetube 22. There are of course other conventional types of flushing systems, incorporating for instance a floating ball valve or other type of floating valves which cause the cistern to stop filling when a required water level therein is detected. - FIGS. 2 to 9 show a first
toilet flushing arrangement 30 according to the invention fitted to the system 10 shown inFIG. 1 . Thearrangement 30 comprises an open toppedhousing 32 with an opening 33 in thebase 34 thereof through which flushing water can pass. In plan view thehousing 32 has a generallycircular front section 36 extending from a smaller generally rectangularrear section 38. These shapes are chosen so as to not cover and thus permit free access to, theconventional mounting holes 39 for thecistern 20. An opening 40 is provided on the side of thehousing 32 towards thebase 34 thereof, on the left hand side as shown inFIG. 2 . - A
closure 42 is provided for the opening 40 in the form of agate 44 which is pivotally mounted byprojections 46 thereon to the outside of thehousing 32. An upwardly extendingbar 48 is provided at the free end of thegate 44, which mounts towards its upper end one end of aspring 50. The other end of thespring 50 is mounted to a hole adjacent the top of thehousing 32 on an opposite side thereof. Thespring 50 urges thegate 44 to a closed position. - A
control arrangement 52 is provided for selective opening of thegate 44 as follows. Thecontrol arrangement 52 connects to thelever 14, and includes arectangular plate 54 which is mounted in thecistern 20. Ashaft 56 extends from thelever 14 through ahole 58 in theplate 54. Acam member 60 is mounted on the free end of theshaft 56 within the cistern. The cam member comprises alower part 62 providing a cam surface engageable against thebar 16 towards the left hand end thereof, as shown inFIG. 2 . Thecam member 60 also comprises a diametrically oppositeupper part 64 in the form of a finger with an opening 66 therein to receive one end of acable 68 which connects to ahole 70 provided at the upper end of thebar 48. - The
bar 16 is pivotally mounted towards its left hand end as shown inFIG. 2 by aprojection 72 on theplate 54 which engages in ahole 74 provided on a projectingpart 76 of thebar 16. The end of thebar 16 extending from theprojecting part 76 is substantially straight and engages with the cam surface of thelower part 62. - In use, if only a low volume flush is required, the
lever 14 is pressed downwardly until any particular resistance is felt. This causes flushing in a conventional manner with thecam member 60 engaging against thebar 16 lifting thelink 18 and henceflush valve 12, thereby causing water to be flushed into the toilet. The water flushed is however only the volume within thehousing 32 and also the volume spaced above the top of thehousing 32 i.e. that between thelines FIG. 6 . - When it is required to have a higher volume of flush, the
lever 14 is pushed further down against the felt resistance, which is in fact provided by thespring 50. This causes further rotation of thecam member 60, which does not cause further pivoting of thebar 16 as thecam member 60 will be moving from the position shown by dotted lines inFIG. 8 . This rotation does though cause thecable 68 to pull thebar 48 away from thehousing 32 against the force of thespring 50, and hence open thegate 44. Therefore in this flush all the water above the line 82 (FIG. 6 ) which is level with the bottom of theopening 40, will flush, irrespective of whether this water is in thehousing 32 or outside thereof. -
FIG. 10 shows analternative housing 84 of a second arrangement, whichhousing 84 in this instance is cylindrical. Ahole 86 which could be cut by an installer is shown, which would locate around the flush outlet of a cistern. Whilst inFIG. 5 theflush valve 12 is shown as a single unit with thehousing 32, the arrangement can readily be retrofitted to an existing toilet flushing system with a housing such as thetype 32 or thetype 84. - FIGS. 11 to 13 show components of a third arrangement.
FIG. 11 shows ahousing 90 which in plan view has anarcuate end 92, which would normally be located towards the rear of a cistern, with two inclined convergingside walls 94 extending from the ends thereof, which are connected by acurved apex 96. Apanel 98 is provided in each of the walls delimited by a line ofweakness 100. A respective one of thepanels 98 can be removed to provide respectively left handed or right handed operation of the arrangement as required. Further, selectively removable openings 99 are provided in an upper part of thehousing 90 to allow the effective height of the housing to be selected. -
FIG. 12 shows aclosure 102 which can be mounted to respectively selectively close either of the openings formed by removal of a respective one of thepanels 98. Theclosure 102 has two vertical inwardly facingpins 104 locatable in asemi-circular recess 106 of ahinge plate 108 shown inFIG. 13 . Theplate 108 is mountable to thehousing 90 adjacent a respective opening by a mountingflange 110 using for instance holes 112 in theflange 110, or using glue. Abar 114 extends from the top and bottom of theclosure 102 for engagement with an operating arrangement similar to that shown for thearrangement 30. - Various other modifications may be made without departing from the scope of the invention. For instance, an upper part of the housing could be provided with markings and/or lines of weakness to enable the housing to be cut to a required height for a particular toilet system. Alternatively, selectively removable openings or cut outs can be provided in an upper part of the housing which could be removed as required to provide an effective top height of the housing.
- There are thus described arrangements which provide for a simple yet effective way of providing a dual flush in a toilet flushing system. The arrangements can be selected to provide a required volume of water in a low volume flush. The arrangements can readily be retrofitted to existing toilets, or supplied new as a complete unit. The arrangements are of relatively simple construction and can thus be inexpensively and robustly manufactured.
- Whilst endeavouring in the foregoing specification to draw attention to those features of the invention believed to be of particular importance it should be understood that the Applicant claims protection in respect of any patentable feature or combination of features hereinbefore referred to and/or shown in the drawings whether or not particular emphasis has been placed thereon.
