Abstract

A locking ring metal (10) includes binder rings (12, 14, 16) each formed by a pair of complementary shaped binder ring halves. Each ring half has an end attached a frame (18, 20). The frames are movable relative to each other to open and close the binder rings and are installed in a housing (22) at one end of which a trigger (11) is mounted. A travel bar (34) installed within the housing above the frames and not connected to the trigger includes blocking elements (50) which fit into respective brackets formed on the underside of the frames when the binder rings are closed to lock the binder rings in their closed position. A coil spring (48) attached to the travel bar and the housing biases the travel bar in the direction to open the binder rings.
