| Abstract: |
An anti-graffiti apparatus is for deterring taggers from performing tagging on private or public property such as freeway sound walls, freeway signs, tunnels, bridges, buildings, and other similar structures. The anti-graffiti apparatus is mounted adjacent to the top of the building wall. The anti-graffiti apparatus has a protective armor which protects the components of the anti-graffiti apparatus. The anti-graffiti apparatus has at least one sensor which is electrically connected to at least one in-line water valve which in turn is connected to a series of sprinkler spray heads which will spray water or other graffiti removing substances onto the walls. The sensor is mounted within the protective armor and directed down towards the ground and is adjacent the side wall of the building where graffiti is likely to occur. When someone comes adjacent the wall anywhere along the cover range of the sensor, the motion of the person will automatically activate the sensor which will in turn open the valve to cause the sprinkler heads to spray water or other anti-graffiti substance onto the walls and onto the tagger.

What is claimed is:
1. An anti-graffiti apparatus in combination with a wall of a building which has a specific area and a main water supply line for deterring a tagger from performing tagging, the apparatus comprising:
- a. an elongated protective armor mounted on said building wall and having one panel approximately at a 45° angle facing the ground, the panel having at least three apertures;
- b. at least two side-by-side adjacent sprinkler heads mounted within said protective armor and protruding out from a respective two of said at least three apertures of said panel for respectively spraying water against said specific area of said building wall and at the tagger;
- c. a water supply conduit mounted within said protective armor and connected to said at least two side-by-side adjacent sprinkler heads for supplying water to said at least two side-by-side adjacent sprinkler heads;
- d. at least one in-line valve mounted within said protective armor and having one end connected to said water supply conduit for controlling the water flow to said at least two side-by-side adjacent sprinkler heads and the other end connected to said main water supply line;
- e. at least one passive infrared sensor mounted within said protective armor and protruding out from a respective one of said at least three apertures of said panel for detecting the presence of the tagger within said specific area, the at least one passive infrared sensor causing activation of said at least one in-line valve which in turn activates said at least two side-by-side adjacent sprinkler heads, thereby spraying water onto said building wall and the tagger;
- f. timer means electrically connected to said in-line valve for controlling the time limit to deactivate said at least two side-by-side adjacent sprinkler heads from spraying water; and
- g. means for electrically powering said anti-graffiti apparatus, whereby when motion is sensed by said at least one infrared sensor, said at least one infrared sensor activates said in-line valve which in turn activates said at least two side-by-side adjacent sprinkler heads to spray water on said building wall and the tagger, thereby deterring the tagger from performing tagging on said building wall.
