- (a) a basket having an inside level and an outside level, said outside level being higher than said inside level, said basket further including first and second laterally spaced female track sections located on a bottom face of said basket;
- (b) a handle;
- (c) first and second pairs of vertical members extending downward from said basket, said first and second pairs of vertical members being laterally spaced from one another;
- (d) at least one wheel attached to at least one vertical member of each of said first and second pair of vertical members;
- both vertical members of said first vertical member pair each pivotably connected at respective lower ends to a first lateral side of a longitudinally extending frame;
- both vertical members of said second vertical member pair each pivotally connected at respective lower ends to a second lateral side of said longitudinally extended lower frame;
- both vertical members of said first vertical member pair each pivotally connected at respective upper ends to a first male track section;
- both vertical members of said second vertical member pair each pivotably connected at respective upper ends to a second male track section spaced laterally from said first male track section;
- said first and second male track sections adjacently slidably connected to said first and second laterally spaced female track sections, respectively, further forming a slidably retractable frame section;
- a lock and release mechanism attached to said bottom face of said basket, said mechanism selectively engaging said vertical members to lock said vertical members into a downwardly extending position, said mechanism selectively releasing said vertical members to allow said vertical members to be retracted;
- said vertical members, said male track sections and said longitudinally extending lower frame forming a rotationally retractable structure wherein said vertical members all simultaneously retract in a rotational direction towards said handle;
