True tracking trailer

A true tracking trailer apparatus comprising:

• first and second generally rectangular trailer vehicles each of which includes;
• a rectangular, planar cargo bed having a front, rear, left and right side and a longitudinal centerline extending between said front and rear sides and a transverse centerline extending between said left and right sides,
• a front inner wall rising perpendicularly from the plane of the bed at said front side and a rear inner wall rising perpendicularly from the plane of the bed at said rear side,
• outer wall means having a front portion disposed forward of said front inner wall and having a rear portion disposed rearward of said rear inner wall whereby a front wheel well is defined between said front portion and said front inner wall and a rear wheel well is defined between said rear portion and said rear inner wall,
• a front castor wheel supporting said vehicle and disposed in said front wheel well,
• a rear castor wheel supporting said vehicle and disposed in said rear wheel well,
• a fixed wheel supporting said vehicle and having an axis of rotation parallel to and aligned with said transverse centerline,
• means connecting said second vehicle to said first vehicle including;
• a first linkage arm pivotally connected at a first end of said second vehicle along a first side of said longitudinal centerline and pivotally connected at a second end to a second end of said first vehicle along a second side of said longitudinal centerline;
• and
• a second linkage arm pivotally connected at a first end to a first end of said second vehicle along a second side of said longitudinal centerline and pivotally connected at a second end to a second end of said vehicle along a first side of said longitudinal centerline;
• whereby said true tracking trailer apparatus may be towed in either direction and whereby said trailer apparatus maintains an essentially constant distance between load centers of said trailers.
