Rolling clear handle / Public handle

The handle in the rapid transit system was used
broadly. It would be considerated that many germs
remained on the handle, and the handle was not
easy to clean, because they were too much and
small.
In this design, designer took the Nano-foam
rubber for the clean media, and constructed in
the rolling axis on the handle. While you used,
just easy to pull down and the other side will
turned up. The part someone used before you
will clear up by pass through the Nano-foam
rubber.
The handle designed in curved surface,
and let the user easy to use. If you won't
to touch the unclean handle, just pull down.
