ergonomic door handle

designer's own words:

the door handle we have designed is made of 2 levels connected to each other by a bar.it is made of metal and it is designed by 3 13 year old students.
we have tried to use the least extra things we could and we have tried to make it as more simple as we can.
but it has got something extra at the end of the lower level to make it easier to use.
