Abstract
A brake system for a rollator may include a brake handle, a braking device operatively coupled to the brake handle, and a gear rim mechanically coupled to at least one wheel of the rollator. The brake handle may be pivotally attached to a frame of the rollator and comprises a service-brake position and a parking-brake position while the braking device may be disposed on the frame of the rollator proximate the at least one wheel. When the brake handle is in a service-brake position, a braking member of the braking device is frictionally engaged with an inner portion of a rim of the at least one wheel thereby braking the wheel. When the handle is in a parking-brake position, the braking member of the braking device is engaged with teeth of the gear rim thereby preventing the wheel from rotating.
