Abstract: A padlock device for the shaft of two-wheeled vehicles, which comprises a pin (3), a lever (4) mounted on said pin (3) and a sliding bolt (8), a sliding lock body (9) actuated by a key (10) and a helical compression spring (11), and means for locking the lever (4) in rotation with respect to the pin (3) which are activated by actuating the key (10) in conjunction with a sliding of the assembly in which said bolt (8) and lock body (9) are capable of adopting forward and rearward operational positions which correspond to the active and non-active states of these locking means.

Abstract: A padlock for motorcycle brake disks having a body with a neck whose width is adjusted to the thickness of a motorcycle brake disk, and a latch which can pass through one of the conventional orifices of this brake disk. The latch operates between a retracted position within the body and an extended position in which it penetrates with its tip into a locking mechanism formed inside the body itself. Once the padlock has been positioned on the disk brake, the body prevents turning of the wheel because it abuts against the motorcycle chassis.

Abstract: Rotary disc lock and key security device characterised in that, in the circular hollow centre of the said separator discs (5) there exist some projecting means (6) which are formed towards the inside and are arranged symmetrically relative to the path of entry of the shaft (2) of the key (1) into the lock, whilst in this shaft (2) there are some recessed means (7) which are reciprocal with the said projecting means (6), and are inter-penetrable with the latter by means of rotary adjustment, the said projecting means (6) operating in conjunction with the said recessed means (7) in relation to the rotary manoeuvre corresponding to the said first typical quarter-turn of the key (1) of rotary-disc locks, and the shaft (2) of which key (1) has, starting from its tip, a smooth area free from the said cut bevels (4), which has a length greater than the distance between two adjacent separator discs (5).

Abstract: This invention concerns a padlock for motorcycle brake disks of a general nature consisting of a body comprising a neck whose width is adjusted by an excessive dimension to the thickness of a motorcycle brake disk, such that one of the conventional orifices of this brake disk can be passed through by a latch that operates between a retracted position within the body and an extended position in which it penetrates with its tip into a locking mechanism formed inside the body itself. Once the padlock has been positioned in the disk brake, it is its own body that prevents turning of the wheel due to the fact that it abuts against the motorcycle chassis.
