Rider-propelled wheeled vehicle

摘要

A rider-propelled wheeled vehicle includes a support surface for supporting a user's feet, which defines a longitudinal axis, a pair of front wheels and a pair of rear wheels associated with the support surface, a system for rotatably connecting the rear wheels to the support surface, and adapted to allow their oscillation about a first oscillation axis inclined with respect to the support surface. The rear wheels have respective first pivot axes independent of and transversally offset from each other for at least partial transfer of the propulsion exerted by the user on the support surface to such wheels and for generation of a reaction substantially parallel to the plane to thereby promote a forward motion of the structure.

1. A rider propelled wheeled vehicle structure, comprising:
a support surface (2) configured to support a user's feet and defining a longitudinal axis (L), said support surface (2) being formed by a first board (6) and a second board (7) which are substantially planar; a pair of front wheels (3, 3′) and a pair of rear wheels (4, 4′) associated with said support surface (2); connecting means (5) for rotatably connecting said rear wheels (4, 4′) to said support surface (2), said connecting means (5) being adapted to allow an oscillation of said rear wheels (4, 4′) about a first oscillation axis inclined with respect to said support surface (2); wherein said rear wheels (4, 4′) have respective first pivot axes (O1, O′1) independent and transversally offset with respect to each other for at least partially transferring to said rear wheels (4, 4′) a propulsion exerted by the user on said support surface (2) and generating a reaction substantially parallel thereto to thereby promote a forward motion; wherein said first board (6) and said second board (7) are reciprocally fastened at respective reciprocally facing and parallel longitudinal edges (9, 10) by hinged means (11) defining a substantially transverse second oscillation axis (O2); and wherein said second oscillation axis (O2) is substantially parallel to said support surface (2), said front wheels (3, 3′) being mounted idle to a transverse common rotation axis (R1) fixed with respect to said support surface (2) and substantially parallel to said second oscillation axis (O2).
