  • Braking assembly for manually operable carriage
    Publication number: 20030141686
    Abstract: A vehicle, such as a wheelbarrow (1) brakes automatically when it runs downhill. A rearward pulling force, naturally applied to handles (4) of barrow (1) by a user when resisting acceleration of barrow (1) down a slope, results in rearward pivoting of, or rearward movement of sleeves on, the handles (4). Such movements are transmitted by linkage (11) (or by cable or hydraulically), to braking mechanism (10) acting on wheel (6).
