Abstract: A ring binder mechanism has D-shaped rings formed by a straight, stationary part, and a movable mating part having an arcuate shape. A recess is formed in the tip of the movable part, and a protrusion at the tip of the stationary part seats in the recess. A lateral window in the recessed tip, intersecting the recess, enables the protrusion to seat smoothly in the recessed tip notwithstanding the fact that the relative motion between the approaching tips has a large lateral component.

Abstract: A binder for releasably retaining loose-leaves. The binder has a front cover that lies flatly beneath its back cover when the binder is open 360 degrees. The rings of the binder can rotate around an edge of the flatly-folded cover to enable loose-leaves to lie flat above and below the cover. The binder also has a skeleton with a minimal cross-section spine which may be partially or completely embedded in a cover and rotates in relation to parallel front and back covers when the binder is open 360 degrees. The front cover, middle cover and back cover are connected in a way so that they do not interfere with the rotation of the rings. Mechanisms to open and close the rings of the skeleton to allow addition or removal of loose-leafs, and ring shapes to optimize or stabilize the capacity of the binder during operation are also disclosed.

Abstract: A modular binder ring unit (16) used in a ring binder (10) comprises a plurality of modules including a binder ring module (18). The modules are spaced along the length of the unit. A plurality of spacer modules (22, 24, 30) attach to the ring modules. The spacer modules are available in different lengths, and a combination of different length modules are usable together with the ring modules to form a binder ring unit of a desired length. The spacer modules space the ring modules an appropriate distance apart for the binder rings to be at locations corresponding to holes (H) in a sheet of paper (S) stored in the binder. End caps (26) are removably attachable at each end of said unit for locking the ring modules and spacer modules in place. Each module element is an elongate module having a recess (R) formed in one end and an extension (E) at the opposite end for securing one module to an adjacent module.

Another partially open ring member is provided that is configured to be slidably received in the slots so that ring member may be moved from an opened to a closed position. A locking device is provided so that the binder may be selectively locked in the closed portion, thereby preventing the unwanted shifting of the members.

Abstract: A ring binder (10) stores hole (H) punched sheets of paper (P). A mechanism (16) is a bolt action mechanism which positively locks binder rings (18) which hold paper in its stored position. Each binder ring includes a fixed section (20) and a movable section (22). All of the movable binder ring sections are commonly mounted on a bolt (36) and move in unison with the bolt. A manually operable lever (38) is secured to one end of the bolt. When the lever is moved in one direction, the bolt is rotated so to move the movable sections of the binder rings away from the fixed sections and open the binder. Operation of the lever in the opposite direction brings the movable sections back into contact with the fixed sections to close the binder.

Abstract: A ring binder (10) holding sheets (S) of paper (P) has a dual angle ring metal (100). The ring metal includes a pair of leaves (102, 104) hingedly connected to each other for relative movement between them. Binder rings (114, 116, 118) each include a pair of ring halves with one end of each ring half being attached to a separate one of the leaves. A shield (30) covers the leaves. Release levers (140, 142) at each end of the shield are operable to open and close the binder. The leaves, when the ring binder is closed, form a predetermined angle (A) with respect to each other. Each of the leaves has a segment (122a, 122b, 124a, 124b) by which a second angle (B) is formed between the leaves. This second angle is formed such that the pair of leaves are prevented from movement relative to each other by movement of paper from one side of the binder to the other. However, the plates are readily movable to open the binder by movement of one of the release levers.

Abstract: A ring binder mechanism has a base plate that may be mounted in a binder or the like and preferably two spring closure mechanisms that each comprise a filing pin and a tube perpendicularly secured to the base plate.

A fixing dent is formed in front of a fixing recess which is formed at an upper middle section of the base board for fixing the paper hanging member. Two fixing holes are formed on the rear end of the base board for fixing the file clip. A notch is formed at a middle section of the front end of the base board. Two locating channels are on both sides of the notch for pivotally connecting the paper clip member. Two punching seats extend downward from each punching hole that is formed on the base boards.

Abstract: An improved method and apparatus enable automated assembly of loose-leaf books, preferably photo albums from snap-ring binders of the slant D configuration and pages with peel-back overlays on mounting sheets. The apparatus comprises: a binder conveyor adapted to position a binder at an assembly station such that an upstanding segment of each ring in open position extends upward and has a vertical projection smaller than that of the holes in the pages; a page support positioned above the binder conveyor and having openings therein adapted for alignment with the holes in the pages; and a binder lift mechanism adapted to vertically lift a binder such that a segment of each ring is moved through the openings in the page support and the holes in the pages supported thereby. The process is automated and employs two linearly moving conveyors which intersect to enable positioning the binder with open ring elements at the assembly station.

Abstract: A ring separator has a pair of members disposed in a facing relationship, the members pivotable about a common axis. Each member has an arcuate channel with the channels aligned in a facing relationship to form a bearing passage. A bearing element is placed within the passage and is movable in an axial direction. Each channel has one or more directing grooves, which receive one or more projections mounted on the bearing. As the bearing element moves axially, the projections direct the members along an arcuate path to open and close the rings mounted thereon. Such a ring separator mechanism has few parts and is easily produced by extrusion or injection molding, thus, providing a ring separator of reduce cost and simple construction.

Abstract: In a loose leaf binder the left (2a, 3a) and the right prong parts (2b, 3b) are each disposed on a common carrier plate (4). The carrier plates (4) are pivotably connected to a base plate (5) and can be depressed using a lever (8) against the force of coil springs (11) into a position in which they lie flat on the base plate. By pulling gently on the end of the catch (10) the binder is released and opens due to the force of the springs (11). Even in the opened state it is still possible to turn the sheets from one prong part to another without such turning being hindered by the lever.
