A door can be opened inside and outside is very popular at hospitals and elderly facilities! A Japanese leading shutter maker produced the world’s first door named “Hikuosu” whose meaning is “pull or push to open”!
“Hikuosu” is an universal designed door and can be opened from both side, inside and outside. Its sliding door can be folded in half, either inside or outside. It is mainly adopted at hospitals and facilities for aged where a lot of wheelchair users are staying. The company is one of the major shutter makers in Japan, but they’re developing some other functional doors, too.
