<p>The automatic plug for wash basins, bidets and bathtubs is of the type having the usual hollow cylindrical body and a vertically movable shutter. The shutter has a hollow shaft able to travel in a guide bushing secured to the hollow cylindrical body. Means of snap-locking are provided, co-operating to maintain the shutter in closed position, and a pushbutton can travel in the hollow shaft and is intended to release the snap-locking means upon external command. When the shutter is pushed downward, the snap-locking means maintain it in closed position, while the actuation of the pushbutton produces releasing of the snap-locking means and thus the automatic opening of the shutter under the action of an opposing spring. <IMAGE></p> |
