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).
Claims69
A braking assembly for a hand operated wheel mounted carriage, the carriage including a support structure comprising a platform for receiving and supporting a load, an undercarriage including at least one wheel;
- the braking assembly comprising:
- a control assembly for controlling said carriage and effecting braking by said braking assembly;
- the control assembly operably linked to a braking mechanism capable of engaging said at least one wheel of said carriage to effect braking thereof;
- wherein, said braking assembly moves between a non working state in which the braking mechanism is free of said at least one wheel and a working state in which the braking mechanism engages said at least one wheel to effect braking when said carriage encounters a slope.
A hand operated wheel mounted carriage, the carriage including a support structure comprising a platform for receiving and supporting a load, an undercarriage including at least one wheel;
- the carriage further including a braking assembly comprising:
- a control assembly for controlling said carriage and effecting braking by said braking assembly;
- the control assembly operably linked to a braking mechanism capable of engaging said at least one wheel of said carriage to effect braking thereof;
- wherein, said braking assembly moves between a non working state in which the braking mechanism is free of said at least one wheel and a working state in which the braking mechanism engages said at least one wheel to effect braking when said carriage encounters a slope.
A wheel barrow including a braking assembly including a control assembly operably linked to a braking mechanism for effecting braking of said wheel barrow;
- wherein said braking assembly is responsive to the effects of gravity on said wheel barrow as said wheel barrow negotiates a slope.
