Claim 1
Independent Claim
148 words
An article holding collapsible compartment, comprising: a plurality of concentric ring members comprising an inner ring member, an outer ring member and an intermediate ring member; a first pair of pivot pins pivotally interconnecting said outer and intermediate ring members at diametrically opposite positions; a second pair of pivot pins pivotally interconnecting said intermediate and inner ring members at diametrically opposite positions in 90* spaced relation with respect to said first pair of pins, said ring members lying in a common plane when said compartment is in collapsed position, said ring members lying in separate planes disposed in right angular relation with respect to each other when said intermediate and said inner ring members are respectively pivoted about the axes of said first and second pairs of pivot pins to an article holding position; and, means maintaining said ring members in compartment collapsed and article holding position, respectively.
