Abstract

A two-wheeled vehicle which can be collapsed into a fully compact, retracted condition or expanded into any one of a number of different forms including the form of a cart, a chair or seat and a two-wheeled carrier for an elongated object, such as a two-wheeled carrier for an elongated object, such as a surfboard. The vehicle has an axle provided with a pair of wheels at the opposed ends thereof. First and second U-shaped elements are pivotally connected to the shaft near respective wheels. A flexible sheet is mounted on and extends between the crosspieces of the first and second elements. Third and fourth U-shaped elements are pivotally coupled intermediate their ends on respective first and second elements, and the positions of these third and fourth elements determine the form in which the unit is to assume. A locking bar near each mounting plate frictionally engages the fourth element to releasably lock the latter in its operative position so that the fourth element forms the handle of a cart. Adjustments of the third and fourth elements from the cart locations thereof permits the unit of the present invention to be converted from the cart to a chair and from the chair to a two-wheeled carrier.

Dependent claims

A combination chair and cart unit comprising:

a shaft having ground engaging wheels mounted thereon at the ends thereof;
first and second U-shaped elements each having a pair of generally rigid sides and a crosspiece interconnecting first ends of the sides, the second ends of the sides being rotatably mounted on the shaft;
a flexible sheet secured at the ends thereof to and extending between the crosspieces of the first and second elements and passing partially about the shaft, said sheet having a pair of parts normally extending outwardly from said shaft and being in operative position angularly disposed relative to each other;
third and fourth U-shaped elements, each of the third and forth elements including a pair of generally rigid sides and a crosspiece at first ends of the sides;
means pivotally connecting the sides of the third element with respective sides of the first element;
means pivotally connecting the sides of the fourth element with respective sides of the second element, said fourth element being movable from a first location extending upwardly and away from the second element to a second location extending downwardly and along the third element when the third element is in a position extending forwardly and downwardly from the first element;
and means coupling the adjacent ends of the third element with the ends of the fourth element when said fourth element is in the first and second operative locations thereof.
