  • Patent number: 6213154
    Abstract: A volume adjusting faucet includes a body with an outlet, a switch and an adjust valve, and a rod portion. The rod portion has a through hole at a proper location and vertical to a passageway for containing the adjust valve, which has a valve body and a valve cap both provided with an annular groove for a O-shaped ring to fit therein. The valve body has a small neck portion with a vertical hole. Then the valve body is inserted in the through hole from one side, and the valve cap is inserted in the through hole from the other side to screw with the valve body together. If the adjust valve is rotated by the switch, the angle between the through hole and the passageway is altered to alter the volume of water flowing out. Further, the small neck portion enables water to flow with the minimum volume even if the through hole and the passageway form 90 degrees, achieving the function of water saving.

  • Patent number: 5813059
    Abstract: A two-stage water-saving flushing device adapted to be fixed in a toilet tank includes an overflow tube made up of one outer tube and one filter tube extensibly connected with the outer tube to be applied to different-sized toilet tanks. The flushing device further has a pressing unit which has a base plate with a cylinder for housing a pressing tube and a function rod inserted through the pressing tube. The function rod is pressed down to flush a large amount of water, and pulled up to flush a small amount of water, by a first arm pulled up to lift a valve of a low-level exit tube connected with the first arm with a chain, and by a second arm pulled up to lift a valve of a high-level exit tube connected with the second arm with a chain.

  • Patent number: 4805654
    Abstract: This invention provides a sun shield for automobiles. The sun shield has a collapsible framework for supporting a flexible cloth. The framework has at least three legs radially and isometrically extended from the framework. In the free end of each leg there is a sucker adapted to attach to the roof of an automobile. Therefore, the cloth can be easily mounted above an automobile to shade it from the unpleasant and damaging effects of the sun's rays, and it can also be easily detached from the roof of the automobile and folded into the trunk of the automobile.
