Definitions

  • the present invention relates generally to toilets, and more particularly to toilet flush and refill mechanisms, and still more particularly to a toilet flush and refill mechanism actuated by a button operatively connected to an air piston or a sheathed push wire.
  • Conventional toilet flush mechanisms employ a mechanical linkage comprising a handle having an interior arm connected to a chain.
  • the chain is connected to a flush valve which includes a rubber flapper covering the 2-3 inch diameter toilet tank drain hole.
  • the rubber flapper typically a buoyed flapper
  • the handle is depressed, the chain lifts the rubber flapper (typically a buoyed flapper) to expose the drain hole and water is rapidly released into the toilet bowl.
  • a filler float descends and triggers a filler valve to open.
  • the rubber flapper follows the water level back down until it is again seated on the drain hole and the tank and the toilet bowl are refilled to the desired level.
  • Gilley US Pat. No. 5,291 ,620, discloses a push button toilet flushing apparatus, comprising a flapper assembly for opening and closing access to a drain from the storage tank.
  • a trigger assembly for initiating a flush includes a trigger arm with one end engaged with the push button and the other end adapted to engage a distal arm of a pivotal lever arm, the lever arm carrying a buoyant float. Pushing the button causes disengagement of trigger arm and the lever arm and causes the lever arm to rise, and the lever arm engages the flapper assembly to open the drain.
  • the apparatus described in Gilley is actually a more complex assembly than conventional flushing mechanisms.
  • U.S. Pat. No. 5,319,810 to Metzger, teaches a toilet flushing arrangement designed to encourage keeping the toilet seat and cover in the closed position when the toilet is not in use.
  • the arrangement includes a flexible line having an inner end connected to an internal flush valve and an outer end automatically detachably connectable to a toilet seat cover, when the cover is moved to a vertical open position, so that, when the cover and seat are moved toward a horizontal closed position, tension on the line will lift the flush valve causing the toilet to be flushed.
  • a much earlier apparatus disclosed in U.S. Pat. No. 3,936,889, to Wibroe, comprises toilet flush mechanism that includes a handle that may be selectively pushed and rotated when a full (rather than partial) flush is desired.
  • the mechanism incorporates a pivotable member attached to a float arm which serves to close the opened tank valve as the float arm descends to limit the amount of water dispensed by the tank.
  • the pivotable member is rotated away from engagement with the tank valve to permit the tank valve to remain open until a full tankful of water has been dispensed from the tank.
  • the present invention is a push button actuated toilet flush apparatus that simplifies and modernizes its prior art predecessors, hi accordance with the present invention, there is provided an improved mechanism for initiating a toilet flush and the subsequent refill of the toilet tank.
  • the inventive apparatus comprises
  • Still a further object of the present invention is to provide a button actuated toilet flush and refill mechanism that is less prone to mechanical failure.
  • Yet another object of the present invention is to provide a button actuated toilet flush and refill mechanism that is elegant in design and appearance.
  • a still further object of the present invention is to provide a button actuated toilet flush and refill mechanism that is essentially silent when operated.
  • FIG. 1 is a perspective view showing the button actuated toilet flush and refill mechanism of the present invention installed in a toilet tank;
  • FIG. 2 is a side elevation schematic view showing the functional elements of the pneumatic push button mechanism employed in a first preferred embodiment of the present invention.
  • FIGS. 1 and 2 wherein like reference numerals refer to like components in the various views, there is illustrated therein a new and improved button actuated toilet flush and refill mechanism, generally denominated
  • FIGS. 1 and 2 wherein like reference numerals refer to like components in the various views, there is illustrated therein a new and improved button actuated toilet flush and refill mechanism, generally denominated 100 herein.
  • FIGS. 1 and 2 illustrate a first preferred embodiment of the invention, showing that the apparatus comprises, in its most essential aspect, a push button assembly 110, mounted in the front side 120 of a conventional toilet tank 130.
  • the push button assembly is preferably a momentary button having a push-to-activate action and comprises a push button 140 in a first housing 150, which may be a pneumatic housing, hydraulic housing, or flexible wire housing.
  • the button device includes a button head 160 which is in an elevated configuration 170 (Position 1) when the mechanism is ready for flushing and fully depressed configuration 180 (Position 2) when pushed to actuate a flush.
  • the push button is integral with a piston 190 and piston head 200, the latter having an outer surface 210 in sealing engagement with the interior wall 220 of the first housing through an O-ring seal 230 when such housing is a pneumatic or hydraulic housing.
  • a fluid seal is not imperative for actuation of a flexible wire device.
  • the first housing 150 preferably includes a fluid (i.e., liquid or gas, including air) inlet 240 having a check valve 250 incorporated into the fluid inlet. It further includes a fluid outlet 260 having a check valve 270 incorporated into the fluid outlet. Finally, a compression spring 280 is disposed between the piston head 200 and the sealed end 290 of the first housing and is employed to urge the piston head into the elevated configuration when the user releases the button.
  • a fluid i.e., liquid or gas, including air
  • a fluid outlet 260 having a check valve 270 incorporated into the fluid outlet.
  • a compression spring 280 is disposed between the piston head 200 and the sealed end 290 of the first housing and is employed to urge the piston head into the elevated configuration when the user releases the button.
  • the push button assembly 110 is in fluid communication with a flapper actuation mechanism 300 through a fluid line 310.
  • the flapper actuation mechanism comprises a second housing 320, which, again, may be a pneumatic, hydraulic, or flexible wire housing.
  • the second housing has a fluid inlet 330 with a check valve 340 disposed therein.
  • It further includes a piston 350 having a piston head 360 with an outer side 370 in sealing engagement with the interior side 380 of the second housing 320, preferably by means of an O-ring seal 390, much as with the first housing assembly.
  • the piston head includes a small fluid passage 360a, which is dimensioned to permit a slow flow of fluid (including, without limitation, air and/or hydraulic fluid) to pass during operation of the mechanism.
  • a compression spring 400 is disposed between the piston head 360 and the ceiling 410 of the second housing.
  • the piston further includes a mechanical connection 420 which is operatively connected to the rubber flapper valve 430 through a chain 440 and arm 450 assembly.
  • the flapper actuation mechanism 300 is preferably mounted proximate the upper end of the overflow tube 460.
  • the pneumatic components of the system may be replaced with mechanical elements comprising a push wire slidingly inserted into a sheath and connected at one end to the push button and at the other end to the mechanical connection to arm 450, employing means well known in the art. While this embodiment does not have the advantage of prohibiting a continual flush, its mechanical simplicity reduces manufacturing costs.
  • the push button for actuating a flush may itself be located in any of a number of positions proximate the toilet, either to suit the convenience of the user/owner, or to comply with regulatory rules, such 4.27 of the ADA Accessibility Guidelines for Buildings and Facilities, concerning controls and operating mechanisms.
  • the push button can be located on the side of the toilet tank, on a sink or counter top close to the toilet, on a wall or stall side near the toilet, or even on the floor immediately in front of or to the side of the toilet.
  • the button can and should be configured so that it can be properly depressed with either a foot or with a gnarled fist, herein.
