Tatsuki Inagaki is Fifteen Years Old and a Third-Year Student in Junior High School from Nakatsugawa City, in the Gifu Prefecture, recently he had an interview to show his newest invention in a demonstration. The mechanism works by pulling on the orange tabs which then releases the security bars, making for an easy escape through the window. The tab is so easy to pull, even a primary school student can use the new invention to escape through the window. Currently, the security bar on windows in Japan is fixed onto the outside of buildings with glue and is acceptable by Japanese building fire codes, which in the case of an actual fire, renders the windows useless as an escape route.

Tatsuki’s invention is a response to the Kyoto Animation Arson in July 2019, Tatsuki mentioned in the interview the confusion about the purpose that Security Bars in Windows had served in situations such as the recent arson:

There are times when a person trying to escape from a window they are prevented from doing so by the security grating… This made me wonder ‘Why is a security barrier, which is supposed to protect lives, actually taking away lives?’
