Abstract

See full text

A ring binder mechanism has an elongate housing constructed of a polymeric material. The housing has a central portion and lateral sides extending downwardly along either side thereof. A ring support is disposed between the lateral sides and is supported thereby for movement relative to the housing. Each of a plurality of rings includes first and second ring members. The first ring member is mounted on the ring support for movement between a closed position and an open position. The mechanism includes a control structure movable relative to the housing. The control structure is adapted to releasably lock the first member in the closed position by blocking movement of the ring support. The control structure comprises a travel bar moveable in translation relative to the housing. The travel bar includes a locking element for engagement with the ring support to block movement of the ring support.
