Abstract
A method and apparatus for retarding rotation of at least one wheel, the apparatus including at least one braking member, a latch member secured to the braking member and movable between a first position and a second position, and a latch actuating member arranged to determine the position in which the latch member is positioned. The braking member is movable into a braking position in which rotation of the at least one wheel is retarded when the latch member is in the second position.
Claims24
A braking apparatus for braking a wheeled vehicle, comprising:
- a wheel for engaging a running surface, said wheel including at least one tooth region;
- at least one braking member associated with the wheel, said braking member being rotatable about a pivot axis between a non-braking position in which the wheel engages the running surface and a braking position in which a brake foot is juxtaposed between the wheel and the running surface;
- a latch member secured to said braking member and movable between a first position in which said braking member is unlatched and a second position in which said braking member is latched to the tooth region of the wheel for rotation with the wheel into said braking position;
- and
- a latch actuating member arranged to interact magnetically with the latch member to determine the position in which said latch member is positioned.

A method for braking a wheeled vehicle, comprising the steps of:
- providing a wheel for engaging a running surface, said wheel including at least one tooth region;
- providing a braking member that is associated with the wheel, said braking member being rotatable about a pivot axis between a non-braking position in which the wheel engages the running surface and a braking position in which a brake foot is juxtaposed between the wheel and the running surface, to which braking member is secured a latch member, said latch member being movable between a first position in which said braking member is unlatched and a second position in which said braking member is latched to the tooth region of the wheel for rotation therewith;
- providing a latch actuating member that interacts magnetically with the latch to determine the position thereof, and
- selecting a position for said latch member via the latch actuating member to control movement of the braking member into the braking position.
