Tencent Digital (Compiler: Human) When the RoChair wheelchair first appeared in 2011, we were attracted by this unconventional wheelchair design driven by the drive rod rowing. Now that RoChair has been redesigned four years later, it has come to us with a new look and appearance that looks more in line with the public's aesthetic, and it is also very interesting to operate.
Generally speaking, most wheelchairs use both hands to roll the wheel forward to achieve the purpose and direction of advancement. This RoChair wheelchair allows us to roll the hub backwards with both hands and allow the hub to rotate by stretching. Get up to achieve the purpose of progress.
As for the benefits of such a design, first of all, pulling the edge of the wheelchair back instead of pushing it forward can make the user's arms more natural force, and better use of the shoulders and back muscles. According to RoChair's inventor, using this design can save 25% of the force needed to advance a wheelchair, and it can also reduce muscle damage caused by prolonged use.
At the same time, this improved RoChair wheelchair also provides some auxiliary power through its special hub design through the center motor, and this design can even be adapted to any existing wheelchair.
However, it should be noted that this wheelchair costs $2,100 (approximately RMB14,160). Basically, if you want to upgrade your existing wheelchair, you will also have to spend a lot.
