Abstract:     The four-wheeled T-handlebar carriage is deliberately designed for the senile and the invalid. The rider can easily operate the carriage with the aid of the T-shaped steering handlebar and drive safely without fear of overbalancing while the provision of four wheels ensures extraordinary stability for the carriage body. A safe and pleasant drive on the carriage is therefore attainable to all the senile and invalid population.
