Definitions

  • the present invention relates to a mechanism for a flushing device for flushing a toilet, comprising a transfer means for transferring a force applied thereto to a connecting member connecting the transfer means to an outlet valve.
  • Toilets typically include a toilet bowl, which is adapted to receive solid and liquid waste and water, and a cistern, which provides a reservoir for the water for flushing the waste from the bowl.
  • a flushing device is mounted within the cistern, which is operable from the outside of the cistern to initiate the flushing.
  • the flushing device may also be arranged to regulate the amount of water entering the bowl during the flushing process.
  • a fill valve may be mounted in the cistern to refill the tank with a predetermined amount of water to be used during the next flushing process.
  • the flushing device may include a flush or outlet valve, one or several floating bodies and an actuation mechanism.
  • the outlet valve opens to release water from the cistern into the bowl and closes when the water reaches a predetermined lower level in the cistern.
  • a float valve opens when water is released from the cistern and closes when the water reaches a predetermined upper level in the cistern.
  • Dual-flush toilets may provide a selection between a flushing with a first water volume for liquid waste and a second water volume for solid waste.
  • a dual-flush toilet includes a selection device accessible from on the outside of the cistern.
  • the selection device is connected to the outlet valve at the bottom of the cistern.
  • the selection device may be connected to the flushing device by shafts, which operate a lever connected to the outlet valve by a connecting member. Depression of a rocker button or separate buttons of the selection device depresses the lever in the direction of the longitudinal direction of the flushing device, whereby the connecting member lifts the outlet valve.
  • the end of the shaft is in constant connection with the lever.
  • Cisterns made of porcelain typically have a variance in height depending on the manufacturing process.
  • the variance for a typical porcelain cistern is ⁇ 6 mm. However other ranges are possible depending on the size of the cistern.
  • the adjustability of the axial distance from the selection device to the outlet valve may be provided by an adjustable shaft extending downwardly from the selection device towards the lever.
  • the length of the shaft has to be determined and the shaft adjusted to accommodate a particular height of the cistern.
  • the shaft may be adjusted by simply cutting it in an appropriate length.
  • the flushing device is useless for taller cisterns. This procedure is cumbersome and has to be carried out for each installation.
  • the shaft has threads that mate with threads of the lever, such that the shaft may be adjusted. However, also this procedure has to be carried out for each installation.
  • EP 0 845 560 A1 relates to a flushing installation with a plurality of different flushing volumes being provided with an operating device, which is provided with a lying transmission element connected to lifting means of the flushing installation and two elements connected to the transmission element for operation thereof with a different stroke.
  • US-A-6 081 938 discloses a dual-flush toilet having a flushing device which is operated by a selection device mounted on top of the toilet.
  • the selection unit is connected to the flushing device by means of a shaft operating a lever in the manner similar to that described above.
  • Adjustability of the flushing device to cisterns of different height is provided in that a connecting member connecting the lever to the outlet valve is selectably adjustable by snap fittings.
  • this design reduces the problem of cutting the shaft, the height of the lifting means still has to be individually adjusted to cisterns of different height. This procedure is cumbersome, as the height of the connecting member has to be determined to accommodate a particular height of the cistern. This procedure has to be carried out for each installation.
  • EP- A- 1 191 158 discloses a mechanism for a flushing device for flushing a toilet having the features of the preamble of claim 1.
  • this object is achieved by a mechanism for a flushing device for flushing a toilet having the features of claim 1.
  • the transfer means may be an arcuate lever. Furthermore, the contact surface of the transfer means may have an arcuate cross section.
  • the mechanism may be connected to an actuation unit having a rocker button connected to at least one leg, which is arranged to apply said force to the contact surface when the rocker button is depressed.
  • the actuation unit may be detachably attached to the flushing device.
  • the leg and the contact surface may be arranged to, in operation, cooperate in a mutually sliding relationship.
  • the mechanism may comprise a first and a second transfer means.
  • the first transfer means may be arranged to actuate the connecting member to cause a flushing with a first volume of water when the force is applied to the contact surface of the first transfer means.
  • the second transfer means may be arranged to actuate the connecting member to cause a flushing with a second volume of water, when the force is applied to the contact surface of the second transfer means.
  • a floating body may be displaceably connected to an outer periphery of the flushing device.
  • the floating body is displaceable in the direction of the longitudinal axis of the flushing device and arranged to actuate a hook up mechanism for engagement with a protruding member.
  • the floating body may be slideably attached to a displaceable shaft for regulating a flushing volume.
  • the mechanism may be provided at a first end of the flushing device, and the hook up mechanism may be pivotally connected to the flushing device at a second end thereof:
  • the hook up mechanism is arranged to fail to engage a protruding member connected to the outlet valve when the connecting means and the outlet valve are moved a first distance and arranged to engage the protruding member when moved a second distance.
  • the hook up mechanism is attached to an upper end of the displaceable shaft and arranged to engage the transfer means when actuated.
  • the mechanism according to the invention may comprise a means for displacing the connecting member a first distance when the first transfer means is actuated and a second distance when the second transfer means is actuated.
  • a stopping member of the first or the second transfer means may be arranged to engage a displacement limiting member connected to the connecting member for limiting the amount of displacement of the connecting member and the outlet valve when the first transfer means is actuated
  • a toilet comprising a cistern, in which the mechanism for flushing the toilet according to the invention is mounted.
  • the toilet may comprise a detachable cover for covering an opening of the cistern.
  • the cover may have an opening into which an actuation unit is inserted and attached to the mechanism, which may be adjustably mounted to an outlet opening of the cistern for centering the flushing device to the opening of the cover.
  • the mechanism is automatically adjusted to different heights of cisterns. Such different heights are due to tolerances in porcelain manufacturing. Also, it is an advantage that the quantity of water of the second flush volume may be easily adjusted simply by adjusting the height of the floating body, which is easily accessible from the top of the cistern. Furthermore, it is an advantage of the invention that it may automatically take care of radial misalignment between the legs of the actuation unit and the transfer means.
  • the mechanism can be used without the actuation unit. Thus, the toilet may be tested during manufacturing without mounting the actuation unit, which is an advantage as it saves time and thus reduces manufacturing costs. It is also an advantage that the flushing device may be mounted by a robot as no adjustment of height is necessary.
  • the flushing device is easily accessibly and thus service-friendly. It is an advantage of the hook up mechanism that it is always surrounded by the water, so that it is not exposed to lime deposit, and comprises few parts, wherein it is cheap to manufacture.
