<P>PROBLEM TO BE SOLVED: To reduce the number of components of a predetermined amount draining system for excrement and urine flushing used for a flush toilet tank and simplify the system. <P>SOLUTION: A spindle is provided with an interlocking rod 11, and a swing member for urine flushing 14 and a swing member for excrement flushing 15 are provided on a base fastened to a tank inner wall with the lower parts of the swing members urged toward the spindle. The swing members have peripheral portions 21A, 21B for interrupting the rotation locus of the interlocking rod, respectively, and in the upper ends, notch portions 24A, 24B for receiving therein in a fitting manner the interlocking rod in upward swing state, respectively. Two weights are suspended by chains from the bottom potion of the swing member for urine flushing on the right side, and an interlocking bar 33 of the swing member for urine flushing extends toward the swing member for excrement flushing, while the swing member for excrement flushing has a lower part 35 for receiving the interlocking bar, with the swing members being in standstill positions, respectively. When flushing urine, the interlocking rod fitted into the swing member for urine flushing is released from the locked state by swing movement of the swing member for urine flushing caused by increase in gravity due to exposure of the first weight above the water level. When flushing excrement, the interlocking bar of the swing member for urine flushing is moved because of increase in gravity due to exposure of the second weight above the water level, so that the swing member for excrement flushing swings and an interlocking rod inserted into the swing member for excrement flushing is released from the locked state. <P>COPYRIGHT: (C)2013,JPO&INPIT |
