Abstract
Abstract A two or three-wheeled vehicle, motorized or not, in which the handle-bar and the front fork are hinged to the steering hub so that they can be upset from their normal operative position to a contracted vehicle position reduced in overall dimensions, in which the front wheel center is put underneath the frame front part and the handle-bar is upset in an essentially horizontal way, so reducing the vehicle overall dimensions in length and in its front part height.

Claim 1
Independent Claim
131 words
A two or three-wheeled vehicle having a single front steering-wheel, and comprising a frame having supported thereon adjacent its forward end a rotatable steering hub, a handle-bar connected to said hub for imparting rotation thereto, and being pivotal relative to said hub between collapsed and upright positions, respectively, a fork supporting the front wheel of the vehicle on said hub for steering by said handle-bar, and being pivotal relative to said hub between collapsed and upright positions, respectively, said handle-bar and said fork being pivotal along axes transverse to the hub rotation axis and parallel to the front wheel axis, and means interconnecting said fork and said handle-bar and operative when the handle-bar is pivoted to its collapsed position, simultaneously to cause said fork to be swung to its collapsed position.
Claim 2
Dependent Claim
131 words
A two or three-wheeled vehicle having a single front steering-wheel, and comprising a frame having supported thereon adjacent its forward end a rotatable steering hub, a handle-bar connected to said hub for imparting rotation thereto, and being pivotal relative to said hub between collapsed and upright positions, respectively, a fork supporting the front wheel of the vehicle on said hub for steering by said handle-bar, and being pivotal relative to said hub between collapsed and upright positions, respectively, said handle-bar and said fork being pivotal along axes transverse to the hub rotation axis and parallel to the front wheel axis, and means interconnecting said fork and said handle-bar and operative when the handle-bar is pivoted to its collapsed position, simultaneously to cause said fork to be swung to its collapsed position.
Claim 3
Dependent Claim
