  • Patent number: 4862602
    Abstract: A collapsible drying rack includes a series of horizontal tubular plastic frame elements connected together by corner elements. Each corner element has four hollow tubular arms that telescopically receive the frame members. A pair of integral, longitudinal ridges on each arm engage the inside of the tubular frame members to form an easily releasable connection compensating for variations in manufacturing tolerances of the plastic members. A mesh sheet mounted on the frame, supports a garment such as a sweater, in a sandwiched position for drying.
