  • Urinal mat
    Patent number: 5398347
    Abstract: A urinal mat provided with upstanding baffles to decelerate a stream of urine impinging thereon. The base of the mat is contoured and flexible to conform generally to the geometry within the urinal. Openings through the base are provided to permit liquids to drain through. Optionally provided are upstanding posts to receive a cake of deodorant thereon. An alternative embodiment provides a depression in the base into which deodorant may be deposited during manufacture. A flexible flange depends from an edge of the mat to engage the urinal sidewall in order to direct flush water over the mat.

  • Toilet anti-splash device
    Patent number: 4866793
    Abstract: A textured, contoured toilet anti-splash and silencer device for adjustable mounting on a toilet at the rear, or the front, of the bowl. The device, a contoured, textured maze, disperses urine into the water of the toilet bowl by breaking, without splash, the velocity of the urine stream, containing the urine within the contour, and then directionally draining the urine noiselessly into the water of the toilet. Depending solely upon the needs of the user the maze device can be suspended within the bowl on either adjustable mounts at the back of the toilet or on fixed mounts at the front of the toilet bowl, thereby ensuring that it is able to be positioned out of the way when the seat is lowered. The device is preferably made of molded plastics to ensure contours and for corrosion resistance. A flange on the device induces self-cleaning during toilet flushing in order to keep the device hygienically clean and odor free.
