Abstract: A shield for a ring metal is provided having arcuate band sections at the locations of the rings and intermediate sections therebetween, the intermediate sections having a straight segmental cross section having a lower overhead clearance between the shield and the hinged leaves than the band sections. The hinged leaves abut the intermediate section before tab members formed on said hinged leaves can abut an underside of the band sections, thus upward dents are prevented on the shield. Additionally, the straight segmental configuration of the intermediate sections provides increased resiliency for opening and holding closed the rings of the ring metal.

Abstract: A locking ring binder assembly has a resilient sheet metal cover and a pair of operating levers rotatably mounted on the covers. A detent consisting of a projection on the inside of the cover and a corresponding projection on the operating levers locks the binder in a closed position even though the operating levers are not rotated to an over center position.
