Abstract
A trailer, as for example for towing behind a bicycle, has an upper frame member, a lower frame member and a pair of folding frame units. The trailer may be folded into compact position by collapsing the folding frame units allowing the rotation of the upper frame member toward the lower frame member. The trailer is easy to manufacture and offers a simplified folding procedure over previously known trailers. The trailer may be modified for use as a stroller.
Claims16
A folding trailer comprising:
- an upper elongate frame member having a forward end and a rear end and defining an upper limit of a cargo compartment;
- a lower frame member defining a lower limit of a cargo compartment and having a pair of side members extending from a rear end, the side members being pivotally connected to the upper frame member adjacent its forward end;
- and,
- a pair of folding frame units, each folding frame unit having a first end and a second end, the first end of each folding frame unit being pivotally connected adjacent the rear end of the upper portion and the opposite end of each folding frame unit being pivotally connected adjacent the rear end of the lower frame member,
- 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 member to rotate towards the lower frame member and thereby fold the trailer into a compact position;
- and,
- a displacement means.
