Claim:
A door anti-latch device for preventing a door from latching, the device comprising: a base; means for mounting the base to a door or a door frame; and a lever rotatably mounted to the base so that the lever can rotate about a pivot point from a blocking position to a non-blocking position, the lever including a handle end and an opposing stop end, wherein the pivot point is positioned between the ends of the lever; wherein the lever can be rotated between the open position and the non-blocking position by moving the lever handle end; the lever rotation is in a plane that is generally perpendicular to a door jamb stop surface and generally parallel to a door jamb side surface; and wherein, when the base is mounted to the door or door frame, the lever stop end will prevent the door from latching when the lever is in the blocking position and will not prevent the door from latching when the lever is in the non-blocking position.
