Abstract

A three wheel vehicle is described having two forward wheels that are driven and steerable. The two forward wheels and the single rear wheel are supported by a single-unit platform member molded from an engineering plastic. The platform member includes a plurality of pipe-like attachment clip/handles strategically located both within the bounds of the platform and about the periphery of the platform. The basic vehicle is intended for use by a standing individual. A plurality of accessories are selectively attachable to the platform member by use of the platform clip/handles. They facilitate use of the vehicle by both a seated and a standing individual, and protect the individual from the environment. Attachments that facilitate cargo carrying and protection of the individual are also described. The vehicle is foldable for storage.

means for locating and securing said control pedestal between a generally vertical position for use by the operator and a generally horizontal position wherein said pedestal extends closely adjacent to and substantially parallel with said flat surface portion, and

power source means mounted to said platform in proximity to said first axis of wheel rotation, and coupled for driving at least one of said wheels,

the center of gravity of the vehicle, when empty, being located in proximity to said first axis of wheel rotation, whereby the vehicle is vertically storable when said pedestal is pivoted into said horizontal position and said platform is pivoted to a generally vertical position as said platform rotates about said first axis of wheel rotation.

6. A vehicle in accordance with claim 5 wherein said platform mounts said two wheels in a position at the front of the vehicle with regard to the normal direction of forward movement of the vehicle, and

said control pedestal includes a pivotable lever linked to said two front wheels for turning said vehicle in response to pivoting said lever.

7. A vehicle in accordance with claim 6 wherein said latch elements include bars arranged for accepting clamps of the accessory securable to said bars by an over-center motion.

8. A vehicle in accordance with claim 7 wherein said accessory is a railing which encircles at least part of the sides and one end of said platform when said railing is attached to said latch elements.

9. A vehicle in accordance with claim 7 wherein said accessory is a canopy attachable for protecting at least a portion of said platform.

10. A vehicle in accordance with claim 7 wherein said accessory is a seat for the operator securable to said latch elements on said flat platform surface in proximity to said pedestal controls.

11. In a vehicle which has a platform having a generally flat surface portion with the platform mounting a pair of ground engaging wheels and a power source for driving one or more of the wheels, a control pedestal comprising:

a pair of arms each formed of first and second segments with said first segment including means manually grippable by an operator on the platform,

linkage means coupling said second arm segments to respective ones of the wheels for providing turning control of the vehicle in response to pivoting movement of a said second arm segment, and

first and second means in proximity to the platform for selectively securing said segments relative to one another between a first position wherein said segments are manually pivotable as a unit for permitting the vehicle operator to turn the vehicle and a second position wherein said first segment is secured in a position generally parallel to the platform flat surface,

whereby the vehicle is storable with minimum volume when said segments are in said second position.

12. Apparatus in accordance with claim 11 which includes means connecting vehicle function controlling elements to at least one of said arms for manual manipulation by the operator.

13. A canopy removably attachable to a vehicle platform which has vehicle operating controls and a plurality of latch elements arrayed thereon comprising:

a pair of elongated frame elements,

means retaining said frame elements in parallel relation to one another for defining a rectangularly shaped box having four elongated faces and two end faces with at least part of one elongated face enclosed,

first attachment means in proximity to one of said end faces for removable securement to the platform in a first position with the length of said frame elements generally perpendicular to the platform in enclosing relation to the operator controls, and

second attachment means in association with the said elongated face opposite said enclosed elongated face for removable securement to the platform in a second position with the length of said frame elements generally parallel to the platform,

whereby securement of said frame elements in said first position provides a windscreen for the operator whereas securement in said second position provides a cargo cover.

14. A canopy in accordance with claim 13 wherein the said end face opposite said end face having said first attachment means in proximity thereto is at least partially enclosed.
