Abstract
Anti-theft device of a bicycle wheel includes at least one braking unit having two pads acting on a rim of the wheel and an actuator to control at least one braking unit. The actuator includes two tie-rods pivoting on shafts and is actuated by a key acting on a key cylinder to press the pads on the rim of the wheel. Each tie-rod is driven at one end by a secondary transmitter piston interacting with a primary transmitter piston and driving a receiver piston holding the pad at its other end. The rotational movement of the key cylinder is converted into a translational movement of the primary transmitter piston by an indirect movement converter.
Claims21
Anti-theft device of a bicycle wheel, comprising:
- at least one braking unit comprising two pads acting on a rim of the bicycle wheel;
- an actuator to control said at least one braking unit, the actuator comprising two tie-rods pivoting on shafts, actuated by a key acting on a key cylinder to press the two pads on the rim of the bicycle wheel;
- wherein each tie-rod is driven at a first end by a secondary transmitter piston interacting with a primary transmitter piston and each tie-rod driving, at a second end, a receiver piston holding a respective pad;
- and
- wherein a rotational movement of the key cylinder is converted into a translational movement of the primary transmitter piston by a movement converter.
Anti-theft device of a bicycle wheel, comprising:
- at least one braking unit comprising two pads acting on a rim of a wheel;
- and
- an actuator to control at least one braking unit, the actuator comprising a key cylinder that releases a pulley to actuate springs, via transmission cables, to put receiver pistons carrying the pads under pressure on the rim of the bicycle wheel.
Anti-theft device of a bicycle wheel, comprising:
- at least one braking unit comprising a pad acting on a rim of a rear wheel of a bicycle;
- and
- an actuator to control said at least one braking unit, the actuator comprising a key acting on a key cylinder putting the pad hold, by a pad holder under pressure, on the rim of the rear wheel by a rotational force acting on the key when the anti-theft device is in a braking position, via a drum directly connecting the key cylinder and the pad holder.
