Abstract:
A scooter includes a scooter body with substantially triangular front and rear body portions. The substantially triangular front body portion has a front side and a first connecting side. The front side and the first connecting side of the front body portion form a first acute angle. The substantially triangular rear body portion has a rear side and a second connecting side. The rear side and the second connecting side of the rear body portion form a second acute angle. The first and the second connecting sides are connected so as to linearly slide with respect to one another such that when the scooter body is in an extended state the front side is in a greater distance from the rear side than a distance when the scooter body is in a compact state.
Abstract:
A forecarriage of a rolling motor vehicle (4), comprising a forecarriage frame (16), at least one pair of front wheels, each wheel being connected to a first kinematic mechanism (20) by means of a respective axle journal (60), a roll block system (100) comprising a second kinematic mechanism (110) which is susceptible to take on a free configuration in which it is configured to passively follow the movements of said two front wheels with respect to each other and with respect to the forecarriage frame (16) and a blocked configuration in which it is configured to block the angle formed by a lying plane of at least one front wheel with respect to the ground, said lying plane being orthogonal to the axis of rotation (R'-R', R"-R") of said front wheel.
Abstract:
Braking and centering mechanisms for foot-deck-based vehicles are described. At least one of the at least one rear wheel of the foot-deck-based vehicle is a braking wheel that is pivotally connected to the foot-deck for swivel movement about a rear swivel axis through a range of angular positions. The braking mechanism comprises a brake member coupled to the rear end of the foot-deck. The brake member is configured to move between a braking position in which the brake member is depressed towards the braking wheel and drives a brake surface to a frictionally engaging position at which the brake surface frictionally engages the braking wheel to reduce a speed of the foot-deck-based vehicle regardless of the angular position of the braking wheel within the range, and a non-braking position in which the brake member permits movement of the brake surface away from the braking wheel.
Abstract:
A motor vehicle forecarriage (8) comprising a forecarriage frame (16), a pair of front wheels (10', 10") kinematically connected to the forecarriage frame (16) by means of an articulated quadrilateral comprising a pair of cross members, hinged to the forecarriage frame (16) in correspondence of middle hinges, said cross members being connected together, in correspondence of opposite transverse ends, by means of uprights pivoted to said transverse ends in correspondence of side hinges, each of the uprights guides and supports a stub axle of a front wheel (10', 10") mechanically connected to a rotation pin of the front wheel (10', 10"), each upright extending from an upper end to a lower end, and wherein each rotation pin of the front wheel (10', 10") is comprised between the upper end and the lower end of the corresponding upright.

Abstract:
A two-wheeled vehicle having a two-wheeled vehicle body, and a front wheel and a rear wheel rotatably provided at the front and rear of the two-wheeled vehicle body, wherein the front wheel is steered by a steering system, can comprise: auxiliary wheels connected to the front wheel at both sides of the two-wheeled vehicle body and steered together with the front wheel around the same rotational center by the steering system steering the front wheel; a lifting device for vertically moving the auxiliary wheels so as to adjust a vertical gap of the auxiliary wheels from the ground; and a gap adjusting device for horizontally moving the auxiliary wheels so as to adjust a horizontal gap of the auxiliary wheels from the two-wheeled vehicle body, wherein the auxiliary wheels are spaced from the ground so as to prevent traveling from being disturbed by the auxiliary wheels during travel, and the auxiliary wheels make contact with the ground so as to restrict the inclination, generated when turning, of the two-wheeled vehicle body, thereby preventing the two-wheeled vehicle body from being inclined at a predetermined angle or more.
