Transportable Tray System

A tray system comprising:

• a plurality of trays each comprising convex exterior surfaces, means being operable for securing trays in a stacked position, means being operable for securing an inverted tray in a cover position over another tray, and means for joining to opposing ends of each of said trays;
• means being configured for removably joining said trays to form a train of coupled trays;
• and
• means being operable for transferring a motive force to the train to transport the train over an uneven terrain comprising obstacles in which said convex surfaces enable the train to maneuver around or traverse the obstacles.

A tray system comprising:

• a plurality of trays each comprising a bottom portion and sides forming a volume in which junctures of said sides and said bottom portion are rounded to comprise convex exterior surfaces and concave interior surfaces, said bottom portion and said sides being configured to laterally retain items placed in said volume, each of said sides further comprising a lip structure being operable for securing trays in a stacked position, said trays each further comprising raised corners being operable for securing an inverted tray in a cover position over another tray, said trays each further comprising two loop members disposed on opposing ends of said tray;
• a plurality connecting member being configured to removably join to said loop members to form a train of coupled trays;
• and
• a lead device being configured to removably join to a connecting member removably joined to a loop member of a tray at an end of the train of coupled trays, said lead device being operable for transferring a motive force to the train to transport the train over an uneven terrain comprising obstacles in which said convex surfaces enable the train to maneuver around or traverse the obstacles.
