Abstract
A brake system for a vehicle having a plurality of wheels and a frame comprising a mechanically actuated braking assembly operably coupled with at least one of the wheels and being operable between braking and non-braking conditions, a handle coupled to the braking assembly and being mounted to the frame for pivotal movement about a substantially horizontal axis between first and second positions in each of which the braking assembly is in the braking condition, and an actuating mechanism responsive to movement of the handle from either of the first and second positions for actuating the braking assembly into the non-braking condition.
Claims16
A brake system for a vehicle having a plurality of wheels and a frame, comprising:
- a mechanically actuated braking assembly operably coupled with at least one of the wheels and being operable between braking and non-braking conditions;
- a handle operably coupled to the braking assembly and being mounted to the frame for pivotal movement about a substantially horizontal axis between first and second positions in each of which the braking assembly is actuated to the braking condition;
- and
- an actuating mechanism responsive to movement of the handle from either of the first and second positions for actuating the braking assembly into the non-braking condition;
- a pin coupled to the braking assembly,
- said actuating mechanism including a cam plate coupled to the handle, said cam plate including a camming structure having an arcuate cam path and a retaining structure, said pin movable along the arcuate cam path as the handle is moved between the first and second positions, said retaining structure adapted to releasably retain the pin when the brake assembly is in the non-braking condition.
A method of mechanically operating a braking assembly on a wheeled vehicle, comprising:
- mounting a handle to the vehicle for pivotal movement between first and second positions;
- coupling a pin to the brake assembly;
- movably connecting said pin to a cam plate, said cam plate having an arcuate cam path and a retaining structure so that the pin is movable along the arcuate cam path when the handle is moved between the first and second positions;
- and
- operably coupling the handle to the cam plate so that movement of the handle from either of the first and second positions moves the cam plate and actuates the braking assembly to a non-braking condition, wherein the retaining structure releasably retains the pin when the braking assembly is in said non-braking condition.
