Abstract
A ring mechanism has an elongate body made of a moldable polymeric material and rings for holding loose-leaf pages. Each ring includes a first ring member and a second ring member. The first ring members are movable relative to the housing and the second ring members between a closed position and an open position. At least one ring member for each ring is a separately formed ring member and comprises a ring portion and an anchor connected to the ring portion. The at least one separately formed ring member is formed separately from the body. The anchor of the separately formed ring member is secured to the body for pivoting movement relative to the body. The anchor can be received in a receptacle in the body adapted to receive the anchor.
Claims20
A ring mechanism for holding loose-leaf pages, the mechanism comprising:
- an elongate body including a top, sides extending down from the top, at least one receptacle, and at least one notch in a side of the body, said at least one notch extending to a bottom of the side;
- rings for holding the loose-leaf pages, each ring including a first ring member and a second ring member, the first ring members being movable relative to the body and the second ring members between a closed position and an open position, in the closed position the first and second ring members forming a substantially continuous, closed loop for allowing loose-leaf pages retained by the rings to be moved along the rings from one ring member to the other, and in the open position the first and second ring members forming a discontinuous, open loop for adding or removing loose-leaf pages from the rings,
- wherein at least one ring member for each ring is a separately formed ring member and comprises a ring portion and an anchor connected to the ring portion, said at least one ring member being formed separately from the body and formed separately from the other ring members, and the anchor of said at least one ring member is configured to be snapped into the receptacle in the body for securing the at least one ring member to the body for pivoting movement relative to the body while the ring portion of said at least one ring member is in said at least one notch,
- wherein the separately-formed ring member and elongate body are configured so that the separately formed ring member can rotate unobstructively between the open and closed positions when the anchor is snapped into the receptacle.

A ring mechanism for holding loose-leaf pages, the mechanism comprising:
- an elongate housing made of a moldable polymeric material and having a top and a pair of sides extending down from opposite sides of the top;
- rings for holding the loose-leaf pages, each ring including a first ring member and a second ring member, the first ring members being movable relative to the housing and the second ring members between a closed position and an open position, in the closed position the first and second ring members forming a substantially continuous, closed loop for allowing loose-leaf pages retained by the rings to be moved along the rings from one ring member to the other, and in the open position the first and second ring members forming a discontinuous, open loop for adding or removing loose-leaf pages from the rings,
- wherein at least one ring member for each ring is a separately formed ring member and comprises a ring portion and an anchor connected to the ring portion, said at least one ring member being formed separately from the housing and formed separately from the other ring members, and the anchor of said at least one ring member is configured to be snapped into a receptacle formed in the housing for securing the at least one ring member to the housing for pivoting movement relative to the housing, the top of the housing having an upper surface that is free of raised bumps above the receptacle,
- wherein the separately formed ring member and elongate body are configured so that the separately formed ring member can rotate unobstructively between the open and closed positions when the anchor is snapped into the receptacle.

A ring mechanism for holding loose-leaf pages, the mechanism comprising:
- an elongate housing made of a moldable polymeric material and having a top and a pair of sides extending down from opposite sides of the top;
- rings for holding the loose-leaf pages, each ring including a first ring member and a second ring member, the first ring members being movable relative to the housing and the second ring members between a closed position and an open position, in the closed position the first and second ring members forming a substantially continuous, closed loop for allowing loose-leaf pages retained by the rings to be moved along the rings from one ring member to the other, and in the open position the first and second ring members forming a discontinuous, open loop for adding or removing loose-leaf pages from the rings,
- wherein at least one ring member for each ring is a separately formed ring member and comprises a ring portion and an anchor connected to the ring portion, said at least one ring member being formed separately from the housing and formed separately from the other ring members, and the anchor of said at least one ring member is configured to be snapped into a receptacle formed in the housing for securing the at least one ring member to the housing for pivoting movement relative to the housing, the receptacle being defined in part by a retainer extending laterally inward from one of the sides of the housing toward the opposite side of the housing, wherein the separately formed ring member and elongate body are configured so that the separately formed ring member can rotate unobstructively between the open and closed positions when the anchor is snapped into the receptacle.
