  • a tank 10 of a conventional manual flush toilet “T is shown.
  • the toilet “T” includes a tank (10), a bowl (1 1), a chain (14), a flush valve and flapper (15), and an overflow tube (16).
  • the toilet “T” is flushed by manually depressing handle (12) and attached lever (13) to raise the flapper 15 and allow water in the tank 10 to flow out of the bottom of the tank 10 into the bowl 11.
  • the handle (12) is typically located on the left portion of the front of the tank 10, as shown in Figure 1, though it may also be located on the right or center portions of the tank as well as the left or right sides of the tank or on the lid.
  • the toilet “T” is retrofitted into an automatic flush toilet by replacing the flush handle 12 with a motion detector 20.
  • the motion detector 20 is mounted on the outside of the tank 10 over the hole through which the handle 12 previously extended.
  • the motion detector 20 includes optical sensors 21 that detect motion within its field of view.
  • the motion detector is powered by one or more batteries 29, for example AA batteries, that deliver a signal current along wiring 22 to a gear train 23 driven by a motor 28.
  • the gear train (23) is mounted to a tube (25) that is positioned over the overflow tube (16).
  • the tube (25) is open at the top to ensure that the overflow tube (16) functions properly.
  • the motion detector (21) detects motion at a predetermined level to indicate movement and transmits an output signal to the motor 28 to operate the gear train (23).
  • the gear train includes a lever (24) eccentrically-mounted such that rotation of the lever 24 by the gear train lifts the flush valve chain (14) to lift the flush valve flapper (15) in the same manner as a manual toilet, releasing water from the tank (10) into the bowl (1 1).
  • the operation of the lever 24 is shown by comparing the views of Figures 3 and 4.
  • the toilet “T” is retrofitted into an automatic flush toilet as in Figs 2-4 that utilizes a pivot connection 29 of the connector 27 to the flush valve 15.
  • This pivot connection 29 is attached to the gear train 23 at a point on a gear 26 displaced from the center of the gear 26.
  • the connector 27 of Figs 5 & 6 includes a rod portion and a chain portion, the rod portion being that portion pivotally attached 29 to the geai chain portion being that portion attached to the flush valve 15.

Abstract

Un appareil de chasse automatique pour convertir des toilettes à chasse manuelle en des toilettes à chasse automatique, et comprenant un détecteur devant être monté sur une paroi extérieure d'un réservoir des toilettes pour détecter une condition prédéterminée pour amorcer une opération de chasse des toilettes. Un transmetteur de signal transporte un signal indiquant l'apparition de la condition, et un moteur est prévu pour être positionné dans le réservoir pour recevoir un courant électrique indicateur de la condition provenant du transmetteur de signal. Une soupape de chasse est positionnée à proximité d'une paroi inférieure du réservoir et est connectée fonctionnellement au moteur pour être actionnée par le moteur lors de la réception par le moteur du courant électrique.
