Lock Hang

Lock Hang is a safety reminder and an easy solution to address the common problem of people leaving things behind in public places, especially public restrooms.

It is common for people to leave their bags behind in public restrooms. Lock Hang works in a simple manner to serve as a reminder. The handle functions as a hanger, a reminder and an indicator of occupancy. When the handle is ajar, it indicates that the cubicle is not in use. After entering the cubicle, one simply places the personal belongings on the handle and the act itself automatically locks the door. 

The handle, when flushed against the door, indicates that the cubicle is in use. When business is completed, personal belongings will have to be removed from the handle to unlatch the lock and open the door. This automatically prevents people from leaving things behind in public bathrooms.
