    摘要： Ring mechanism for loose leaf binders, and method of manufacture therefor, which has actuating or booster levers which serve both to open and close the rings. Mating ring segments or portions are affixed at corresponding spaced locations to a pair of metallic rods or rails. The outer ends of the rods of oval cross section include crank arm portions, with flattened tangs at the terminal ends thereof formed during fabrication on a rail of continuous length which is then severed to provide identical rail and ring segment components. The rail and ring components are then assembled in parallel relation within the inturned edge channels of a spring metal cover plate or case of arcuate cross section which is tensioned to hold the ring segments in closed relation. Each of the booster levers is slotted to engage opposite surfaces of the tangs for pivoting the rods about their longitudinal axes in response to pivotal movement of the booster levers whereby the rings are selectively opened and closed by said levers.

    摘要： The looseleaf binder ring assembly disclosed herein consists of a one-piece backbone formed of a resilient plastic material, which backbone has a plurality of pairs of cooperating fingers formed thereon. The fingers of each pair face one another and are movable between open and closed positions with respect to each other. A slidably mounted actuator bar is provided in the backbone and has cam surfaces formed thereon for respectively opening and closing the fingers when the slide bar is moved between first and second positions. The cam surfaces respectively hold their associated spring fingers in their opened or closed position in accordance with the position of the slide bar.
