Braking system, rollator and transport chair with the same
A braking system is mounted on a rollator or a transport chair and includes a braking part and an operating system. The braking part is mounted adjacent to a wheel of a rollator or a transport chair. When the operating system is unactuated, the braking part abuts a corresponding wheel to avoid a rotation of the corresponding wheel. When a user wants to walk and move the rollator or the transport chair, the user can press the operating system such that the braking part departs from the wheels and releases a brake. When the user wants to sit on the seat cushion and rest, the user can keep the braking system actuated without pressing the operating system, and accordingly the rollator or the transport chair would not be slidable when sat on, thereby avoiding danger. In addition, when the user walks on a slope, the user can release their hands from the rollator or the transport chair without making the rollator or the transport chair slide down the slope.

at least one operating system mounted on the stand, each one of the at least one operating system corresponding to and connected to one of the at least one braking system;
wherein when the at least one operating system is unactuated, the braking part tightly abuts a surface of the corresponding wheel, and when the at least one operating system is actuated, the braking part departs from the surface of the corresponding wheel.
4. The rollator as claimed in claim 3 , wherein the at least one operating system comprises:
an operating part mounted on one of the handles; and
a brake line connected to the operating part and a corresponding braking system, and comprising:
a pipe, and ends of the pipe respectively mounted on the operating part and the fixed board of the braking system; and
a line extending from the ends of the pipe, and ends of the line respectively mounted on the operating part and the connecting part of the braking part of the corresponding braking system.
5. The rollator as claimed in claim 3 , wherein a surface of the braking part of each one of the at least one braking system abutting the wheel is flat.
6. The rollator as claimed in claim 3 , wherein a surface of the braking part of each one of the at least one braking system abutting the wheel is wavy.
