Patent ID: 8240437

Claim:
A brake system for a rollator comprising a frame and at least one wheel rotatably coupled to the frame, the brake system comprising a brake handle, a braking device operatively coupled to the brake handle, and a gear rim mechanically coupled to the at least one wheel, wherein: the brake handle is pivotally attached to a frame of the rollator and comprises a service-brake position and a parking-brake position; the braking device is disposed on the frame of the rollator proximate the at least one wheel such that: when the brake handle is in a service-brake position, a braking member of the braking device advances in a first direction such that the braking member is frictionally engaged with an inner portion of a rim of the at least one wheel thereby braking the at least one wheel; and when the brake handle is in a parking-brake position, the braking member of the braking device advances in a second direction opposite the first direction such that the braking member is engaged with teeth of the gear rim thereby preventing the at least one wheel from rotating.
