Abstract

See full text

The present invention is a safety braking system for a hand-pushed rollator, which allows the user to engage different operation modes: a park mode, a walk mode, and a brake mode. The present invention comprises a wheel mechanism, a cable assembly, and a handlebar mechanism. The wheel mechanism allows a wheel to rotate during walk mode, to engage the wheel with a parking brake during park mode, and to engage the wheel with a friction brake during brake mode. The wheel mechanism pivots the parking brake and the friction brake on a lever in order to switch between the different operation modes. The handlebar mechanism allows the user to shift between the different operation modes and is engaged to the wheel mechanism through the cable assembly. The handlebar mechanism uses two levers that are pushed and pulled by the user in order to shift between the different operation modes.
