Embodiment Construction

[0069] Referring now to the drawings, and first with particular reference to FIGS. 2-11 , one embodiment of a ring binder mechanism is indicated generally at 100 . The mechanism 100 of the present embodiment includes a bracket, generally designated 102 , which supports a pair of hinged plates 128 (generally referred to as "ring supports") and three rings, each generally designated 104 . In FIG. 2 , mechanism 100 is shown mounted on a notebook, generally indicated at 10 . Specifically, the mechanism 100 is shown mounted to the back cover 12 of the notebook 10 by rivets 113 generally adjacent and aligned with the spine 14 of the notebook 10, securing the bracket 102 to the notebook. The rivets 113 extend through mounting holes 123 at opposite ends of the bracket 102 . Cover 16 of notebook 10 is hinged to spine 14 and moves to selectively cover or uncover loose-leaf pages (not shown) held within notebook 10 by mechanism 100 . A ring binder mechanism otherwise mounted on a noteb...

Abstract

A ring binder mechanism includes a housing and a ring support supported by the housing for movement relative thereto. Each ring of a plurality of rings includes first and second ring members. The first ring member is mounted on the ring support for movement with the ring support relative to t he housing between a closed position and an opened position. An actuator is mounted for pivotal movement relative to the housing for moving the rings from their closed position to their opened position. The actuator includes a lower arm having a contact surface engageable with a lower surface of the ring support when the rings are in their opened position and out of engagement with the ring support when the rings are in their closed position. The contact surface defines an angle between its outer surface and a horizontal plane between about 16 degrees and about 55 degrees.

Description

[0001] Related Patent Applications [0002] This application is a continuation-in-part of US Patent Application No. 11 / 932,150, filed October 31, 2007, which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates to a ring binder mechanism for holding loose-leaf pages, and more particularly to a ring binder mechanism having a carrier and an actuator made at least in part of a polymeric material. Background technique [0004] A conventional ring binder mechanism has multiple rings for holding loose-leaf pages, such as punched pages, within a file or notebook. The rings can be selectively opened to add pages to the ring binder mechanism or remove pages from the ring binder, or closed to hold the pages and allow the pages to move along the rings. Each ring includes a pair of ring members mounted on adjacent hinge plates that are connected together about a pivot axis. An elongate bracket, typically metal, supports a hinge pl...
