Claims
- 1. A folding transport vehicle comprising:
- a lower chassis defining substantially a lower limit of a cargo compartment and having a first end;
- an upper frame, formed of at least one elongate member and defining substantially an upper limit of the cargo compartment, the upper frame being pivotally connected to the chassis adjacent the first end;
- at least one folding frame unit, each folding frame unit having a first end and an opposite end, the first end of each folding frame unit being pivotally connected to the chassis and the opposite end of each folding frame unit being pivotally connected to the upper frame,
- each folding frame unit having a pivot point such that the folding frame unit is foldable from an extended position to a collapsed position allowing the upper frame to rotate towards the chassis and thereby fold the vehicle into a compact position; and,
- a displacement means.
- 2. The folding vehicle of claim 1 further comprising a hitch arm extending forwardly from the lower frame member for placing the vehicle in tow.
- 3. The folding vehicle of claim 2 wherein the displacement means are wheels.
- 4. The folding vehicle of claim 2 wherein the displacement means are skiis.
- 5. The folding vehicle of claim 1 wherein the displacement means are at least three wheels.
- 6. The folding vehicle of claim 1 wherein the vehicle is convertible between a stroller, having at least three wheels, a trailer, having a hitch arm and at least two wheels and a sled, having skis and a hitch.
- 7. The folding vehicle of claim 1 wherein the chassis is formed as a molded plastic shell.
- 8. A folding trailer adapted for towing by a bicycle comprising:
- a lower chassis defining substantially a lower limit of a cargo compartment and having a first end;
- an upper frame, formed of at least one elongate member and defining substantially an upper limit of the cargo compartment, the upper frame being pivotally connected to the chassis adjacent the first end;
- at least one folding frame unit, each folding frame unit having a first end and an opposite end, the first end of each folding frame unit being pivotally connected to the chassis and the opposite end of each folding frame unit being pivotally connected to the upper frame,
- each folding frame unit having a pivot point such that the folding frame unit is foldable from an extended position to a collapsed position allowing the upper frame to rotate towards the chassis and thereby fold the trailer into a compact position;
- a hitch arm and a hitch member for attachment to the bicycle extending forwardly of the chassis; and,
- a plurality of wheels.
- 9. The folding trailer of claim 7 wherein the chassis is formed as a molded plastic shell.
- 10. The folding trailer of claim 7 wherein the trailer comprises a pair of folding frame units and a cross bar extending between the folding frame units; and,
- the upper member being formed as a pair of elongate members, each member being pivotally connected to the chassis adjacent its first end and pivotally connected to one of the folding frame units adjacent its opposite end.
