In Asia, bus accidents often result in heavy casualties. Because it is hard to open the door when the bus is full of people, especially at commuting hours. The existing safety hammer can hardly meet the demand of escaping.
Handle Hammer combines the safety hammer with the handrail. At usual times, it collects and stores a small amount of electricity through the swing of the armrest. When an emergency occurs, passengers can push the button to pick up the safety hammer to break the window. At the same time, all handrail screens show escape warning to keep everyone alert.
