Definitions

  • the present invention relates in general to a flushing device for toilet bowls and, more particularly, to a structural improvement in such a flushing device for cleanly flushing a toilet bowl using high water pressure by selectively operating either of two flush levers in accordance with the kind of excrement to be washed away.
  • a typical flushing device for toilet bowls has one flush lever cooperating with a flush valve installed in the bottom of a flush tank.
  • the flush lever In order to flush a toilet bowl having the above device after relieving oneself, the user operates the flush lever.
  • the flush tank has been charged with water to a level limited by a floater in the tank.
  • the lever When the lever is operated as described above, a predetermined amount of water is discharged from the tank into the toilet bowl to flush the toilet bowl. That is, the above flushing device discharges a predetermined amount of water from its flush tank into the toilet bowl regardless of the kind of excrement when a user operates the flush lever after relieving oneself. Therefore, the above flushing device has a problem in that it wastes the large amount of water.
  • This flushing device has two flush levers, that is, a feces lever and a urine lever, which cooperate with their associated flush valves separately installed in the bottom of the flush tank.
  • a feces lever When the feces lever is operated, the full amount of water is discharged from the tank to flush the toilet bowl. Meanwhile, when the urine lever is operated, only about half the water is discharged from the tank to flush the toilet bowl.
  • the urine lever when the urine lever is operated, the water is discharged from the tank using low water pressure not sufficient to completely flush the toilet bowl. With the low water pressure, the operation of the urine lever may be often accompanied with the operation of the feces lever for completely flushing the toilet bowl. Thus, the above flushing device is problematic in that it wastes rather than saves water.
  • an object of the present invention to provide a flushing device for toilet bowls in which the above problems can be overcome and which discharges a predetermined amount of water from the flush tank into the toilet bowl using high water pressure sufficient enough to flush the toilet bowl when either the urine or feces lever is selectively operated in accordance with the kind of excrement to be washed away, the flushing device thus effectively flushes the toilet bowl with the appropriate amount of water and thereby saves water.
  • the present invention provides a flushing device for toilet bowls comprising first and second levers, further comprising an openable flush valve provided in a flush tank to selectively open a water outlet of the tank; a bracket mounted to the top of the flush valve; a rotatable operating rod rotatably coupled to and extending upwardly from the bracket, the rod being selectively lifted up in accordance with the opening motion of the valve and having both a key member at a given portion and a pair of rotating arms at a lower portion; a floater arm cooperating with the operating rod to stop the descending motion of a floater at a predetermined position, the floater arm having a guide member for slidably receiving the top portion of the operating rod and guiding the lifting motion of the rod; and first and second operating links cooperating with the first and second levers respectively, one end of each link being coupled to a lever body having the levers and the other end of each link being connected to an associated rotating arm of the operating rod by means of an associated wire.

  • FIG. 1 is a perspective view showing the construction of a flushing device for toilet bowls in accordance with a preferred embodiment of the present invention.
  • the above device 1 separately includes first and second flush levers, that is, a feces lever 16 and a urine lever 17, and has a bracket 4 which is mounted to the top of an openable flush valve 3.
  • This valve 3 is installed in a flush tank 30 to selectively open a water outlet 2 formed in the bottom of the tank 30.
  • a rotatable operating rod 5 having a key member 5a at the appropriate portion is coupled to the bracket 4 and extends upwardly from the bracket 4.
  • the top portion of the above operating rod 5 in turn is slidably fitted in a guide hole 7b formed in a guide member 7a of a floater arm 7.
  • Mounted to the free end of the arm 7 is a floater 6.
  • the above operating rod 5 is rotatable in opposite directions as shown in Fig. 2.
  • the guide hole 7b formed in the guide member 7a is a key hole suitable for selectively receiving the key member 5a in accordance with rotation of the rod 5.
  • a biasing member 25 for example a coil spring, is coupled to a given portion of the floater arm 7 at one end thereof. The other end of the biasing member 25 is fixed to a water supply tower 26.
  • the flushing device also includes a pair of operating links, that is, the first and second links 11 and 12 which cooperate with the two levers 16 and
  • Each link 11, 12 is coupled to the lever body 10 at one end thereof.
  • the links 11 and 12 also have their holes 11a and 12a at their other ends.
  • the holes 11a and 12a of the links 11 and 12 are connected to their associated wires, 8 or 9 respectively, at one end.
  • the wires 8 and 9 are for feces and urine respectively.
  • the other ends of the wires 8 and 9 are connected to the bracket 4.
  • Fig. 2 is an enlarged perspective view showing in detail the structure for coupling the operating rod 5 to the bracket 4.
  • the bracket 4 mounted to the top of the flush valve 3 has a shaft hole 4a.
  • the shaft hole 4a rotatably receives the lower portion of the operating rod 5.
  • a pair of rotating arms 5b having their holes 5c and 5d are integrally formed on the outer surface of the lower portion of the rod 5.
  • the arms 5b extend radially outward from the rod 5.
  • the rotating arms 5b are disposed under the shaft hole 4a.
  • the wires 8 and 9 extending from the holes 11a and 12a of the operating links 11 and 12 are coupled to the holes 5c and 5d of the rotating arms 5b respectively after passing a guide hole 4b formed in the bracket 4.
  • Fig. 3 is a schematic view of the above flushing device used for washing feces away.
  • the rotating arm 5b of the rod 5 coupled to the wire 8 is turned leftward or rightward, thereby letting the key member 5a of the rod 5 be aligned with the key hole part of the guide hole 7b.
  • the operating rod 5 is lifted up until a stopper 5a 1 provided in the bottom portion of the key member 5a is stopped by the guide member 7a having the guide hole 7b. Therefore, the flush valve 3 is lifted up to open the water outlet 2.
  • the water outlet 3 is opened, the water is discharged from the tank 30 using high water pressure. As the water is discharged from the tank 30, the floater 6 floating on the water surface naturally descends.
  • the flush valve 3 is forcibly closed to stop flushing water before the buoyancy of the floater 6 has been completely consumed.
  • the above flushing device effectively saves water when the device is used for washing away feces.
  • Fig. 4 is a schematic view of the above flushing device used for washing away urine.
  • the rotating arm 5b of the rod 5 coupled to the wire 9 is turned in a direction opposite to the rotating direction of the rod 5 in the case of operating the feces lever 16. Therefore, the key member 5a of the rod 5 is located at a position which diverges from the key hole part of the guide hole 7b. The key member 5a in this state will not pass the key hole part of the guide hole 7b even when the rod 5 is lifted up.
  • the above flushing device As the flushing device used for washing away urine discharges the water from the flush tank 30 until the top end of the key member 5a is stopped by the guide member 7a of the floater arm 7. Therefore, the above flushing device remarkably reduces the amount of water consumed when washing away urine.

  • Fig. 5 is a sectional view showing the structure for coupling the two operating links 11 and 12 to the lever body 10 of the above flushing device.
  • the outer portion 20 of the cylindrical lever body 10 is fitted in the porcelain flush tank 30 and fixed to the tank 30 using a nut 21.
  • the body's middle portion 22 which is coupled to the link 12 is connected to the lever 17, while the body's inner portion 23 which is coupled to the link 11 is connected to the lever 16.
  • the middle and inner portions 22 and 23 of the lever body 10 are rotatable relative to the outer portion 20 fixed to the tank 30.
  • the present invention provides a flushing device for toilet bowls which has two levers, that is, feces and urine levers, cooperating with their associated operating links.
  • feces and urine levers When either the feces or urine lever is selectively operated in accordance with the kind of excrement to be washed away, an operating link cooperating with the operated lever is lifted up to pull up an associated wire.

Abstract

Dispositif perfectionné de chasse d'eau pour cuvettes de W.-C. Ce dispositif décharge dans la cuvette une quantité d'eau prédéterminée provenant du réservoir de chasse, la pression de l'eau étant suffisamment élevée pour rincer la cuvette lorsque l'on actionne de manière sélective l'un des leviers 'urine' et 'matières fécales' en fonction du type de déjection à évacuer. Ce dispositif permet donc de rincer de manière efficace la cuvette au moyen d'une quantité d'eau appropriée, ce qui réduit la consommation d'eau. Le dispositif possède un élément de liaison monté sur le robinet de chasse. Une tige rotative d'actionnement est reliée à cet élément et s'étend vers le haut à partir de celui-ci. Un bras à flotteur coopère avec la tige d'actionnement de manière à bloquer dans une position prédéterminée le déplacement vers le bas d'un flotteur. Une paire de liaisons d'actionnement coopèrent avec des leviers respectifs.
