Patent attributes
A self-cleaning urinal anti-splash device having a series of angled deflectors which send the urine stream ever deeper into a series of channels leading down toward the urinal drain. The angled deflectors not only send the urine stream ever deeper into the channels, but they simultaneously prevent the urine from exiting the channels in any direction other than downward toward the drain. This is accomplished by virtue of the fact that inner faces of the deflectors are adapted to deflect the urine back toward the urinal wall. No plane perpendicular to the direction of the initial urine stream is presented to the user. Gravity then causes it to flow to the drain. The device is also self cleaning because there is nothing to prevent the water of a flush cycle from passing through the vertical channels by gravity feed, thereby removing all the urine on the deflector surfaces. The device can be made of metal, plastic, rubber, or other inexpensive easily moldable substance. It has notches in the channels so the device is easily trimmed to size.
