Abstract
A ring metal (M) installed in a binder (B) stores punched sheets of material and the like. The ring metal includes binder rings (R) mounted on movable frames (F) to which one end of each ring half is attached. The frames are movable relative to each other to open and close the rings. A ring guard (10) is removably installable over a portion of each ring half, when the binder ring is closed, to securely encompass rings halves (12, 14) forming the ring. The guard encloses the junction (J) where outer ends of the ring halves meet when the rings are closed and prevents a gap from opening between the ring halves if the binder is subjected to a force which would otherwise cause a gap to form between the ring halves and material stored in the binder to spill out or be damaged.
Claims19
In a binder ring metal holding hole punched sheets of material and the like, the ring metal including at least one binder ring formed by a pair of binder ring halves, and movable frames to which one end of each ring half is attached for movement of the frames to open and close the binder ring, the improvement comprising:
- a ring guard removably installable over the binder ring, when the binder ring is closed, and covering at least a portion of each ring half including a junction where outer ends of the ring halves meet when the binder ring is closed, the ring guard securely gripping the binder ring and preventing a gap from opening between the ring halves when the binder is subjected to a force which would otherwise cause a gap to form between the outer ends of the ring halves and the material stored in the binder to spill out or be damaged.
In a binder ring metal holding hole punched sheets of material and the like, the ring metal including a plurality of binder rings each of which is formed by a pair of binder ring halves, and movable frames to which one end of each ring half is attached for movement of the frames to open and close the binder rings, the improvement comprising:
- a ring guard removably installable over each binder ring, when the binder rings are closed, and covering at least a portion of each ring half of each binder ring including a junction where outer ends of the ring halves for the respective binder rings meet when the binder is closed, each ring guard securely gripping its associated binder ring and preventing a gap from opening between the ring halves of the binder ring when the binder is subjected to a force which would otherwise cause a gap to form between the outer ends of the ring halves of a binder ring and the material stored in the binder to spill out or be damaged.
