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 to a frame (18, 20). The frames are movable relative to each other to open and close the binder rings. The frames are installed in 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, when in position, prevent movement of the frames to lock the binder rings in their closed position. A coil spring (48) attached to the travel bar and housing biases the travel bar in the direction to open the binder rings.
