Self-storing roller conveyor extension

A roller conveyor extension comprising:

• a base frame including first and second laterally spaced, elongated tracks arranged in parallel, each of the first and second tracks having a rearward end and a forward end;
• a roller support structure including first and second laterally spaced, elongated frame members arranged in parallel, each of the first and second frame members having a first end and a second end coinciding with, respectively, back and front ends of the roller support structure;
• a plurality of rollers supported by, and extending between, the parallel frame members of the roller support structure;
• and
• a first carriage adapted for translating reciprocation between the reward and forward ends of the first track and a second carriage adapted for translating reciprocation between the rearward and forward ends of the second track, the first and second carriages being pivotably attached to, respectively, the first and second elongated frame members of the roller support structure in a location less distant from the back end of the roller support structure than the front end of the roller support structure such that the roller support structure is capable of both rotational motion about a pivot axis and rearward and forward reciprocating motion with respect to the base frame.
