Abstract
An indication box used with an electronic smart lock indicates if a public service room is in use. A color plate partially shown in a window moves vertically up and down with door handle motion. Unlike other indicators, the door handle and not lock actives use indication to avoid mishaps from forgetting to lock the door. The color plate is spring loaded with a V-shaped bottom. The color plate vertically moves by a cam having two L-shaped portions forming a V-shaped recess to initially secure the color plate's V-shaped bottom. Cam activation is through a dial head that moves with the door handle. When the color plate indicates use, the V-Shaped bottom rests on one of the cam's L-shaped portions. The color plate may also include braille markings. The indication box is used on a door's front portion with any electronic smart lock design and operates without electrical power.
