RING BINDER WITH INTERLOCKING RING MEMBERS

摘要

A ring binder for use in holding loose-leaf pages. A retaining system is configured to selectively and releasably hold first and second ring members in a closed position. First and second interlocking formations are selectively movable relative to one another between a retaining position and a non-retaining position. The first interlocking formation includes a projection having a free end. The free end has a void configured and arranged to permit resilient bending of portions of the free end of the projection in a first direction as they engage the second interlocking formation when the interlocking formations are moved from the non-retaining position to the retaining position. In the retaining position, the portions of the free end of the projection are substantially inhibited from bending in a second direction in response to pivoting movement of either of the ring members.

主权项

1. A ring binder for use in holding loose-leaf pages, the ring binder comprising:
an elongate base; rings for retaining loose leaf pages, each ring including first and second ring members movable relative to one another between a closed position in which the first and second ring members together form a substantially continuous closed loop and an open position in which the first and second ring members form a discontinuous open loop, at least one of the first and second ring members being hingedly connected to the elongate base for selective pivoting movement toward the open and closed positions; and a retaining system configured to selectively and releasably hold the first and second ring members in the closed position, the retaining system comprising first and second interlocking formations adjacent ends of the first and second ring members, respectively, the first and second interlocking formations being selectively movable relative to one another between a retaining position in which the retaining system holds the first and second ring members in the closed position and a non-retaining position in which the retaining system does not hold the first and second ring members in the closed position, the first interlocking formation comprising a projection having a free end, the free end having a void configured and arranged to permit resilient bending of portions of the free end of the projection in a first direction as they engage the second interlocking formation when the interlocking formations are moved from the non-retaining position to the retaining position, wherein said portions of the free end of the projection are arranged relative the void so that in the retaining position said portions are substantially inhibited from bending in a second direction in response to the pivoting movement of said at least one of the ring members.
