Abstract: An adjustable binding system with a binding portion that can bind together papers, dividers, a backing, and other material. The binding portion can open and close to facilitate organizing, adding, removing, etc. The binding portion can have hinged parts that connect mating pairs of binding elements, such as protrusions inserted into hole-punched paper, and connected to another element to form a binding within the binding portion. The binder can have a minimal profile to provide a customizable binder with the feel of a disposable notepad.

Abstract: The present invention provides an unitary spine binder which comprises an elongated dorsal hinge bearing pairs of opposing and complementary male and female ring elements having known male fastener and female fastener, respectively. Each pair of ring elements also comprise a concave distal end on one element, and a complementary convex distal end on the other element. When the distal ends of the ring elements are moved towards each other, the male and female fasteners reversibly engage with each other so that each pair of ring elements, in cooperation with the dorsal hinge, forms substantially a ring to secure sheet paper by occupying a pre-punched hole in the paper. At the same time, the concave and convex distal ends also engage, so that the sidewalls of the concave distal end engages the convex distal end to protect the fasteners against disengagement by torsional and lateral forces.

Abstract: A safety ring binder mechanism helps prevent finger pinching by requiring simultaneous opposite movement of sliding actuators at both ends of the mechanism in order to open and close the rings. When the actuators are outermost, dimples on the actuators press the blades of the device against the housing, holding the rings open. When the actuators are pushed in, inclined tongues cam the ends of the blades downward, forcing the rings to close and holding them in a closed position.

Abstract: A binder mechanism is disclosed having a first ring assembly and a binding portion. The first ring assembly includes at least one first ring half. At least the first ring assembly or the binding portion are a pivotable half that is pivotable with respect to the other to a locked position about a first longitudinal axis. In the locked position, the first ring half is engaged with the binding portion cooperatively defining a loop that is substantially closed to retain a stack of papers or a workpiece. The first ring assembly and the binding portion are lockable with respect to each other in the locked position to prevent pivoting of the pivotable half from the locked position. At least one of the first ring assembly and the binding portion is movable with respect to the other from the locked position in an unlocking direction oriented at less than 180° from the longitudinal axis to permit the pivotable half to pivot about the longitudinal axis to an open position in which the loop is substantially open.

Abstract: A binder with a security lock feature having front and back cover panels connected by a spine, and a page-holding mechanism attached to the spine on the inside of the binder for releasably holding pages in the binder. The page-holding mechanism includes a post assembly having a plurality of posts extending generally transversely of the spine at locations spaced longitudinally of the spine for holding pages in the binder. Each post is made up of a pair of interengageable post elements separable to permit pages to be inserted into and removed from the binder. The post assembly is movable between a first position in which the post elements of each post are interengaged and inseparable, and a second position in which the post elements are separable. A latching member is movable between a latching position for latching the post assembly in the first position and a release position for enabling the post assembly to be moved to the second position.

Abstract: A record keeping assembly has a binder with locating elements spaced along the length of the outer side edge of a panel and a shingled assembly of overlapping elongated sheets with apertures along the one side thereof through which said locating elements extend. Under the shingled assembly is a flexible peel strip which has one end secured to the panel adjacent the outer side and which extends along the locating elements across the panel and projects outwardly therefrom. This peel strip is gripped by its projecting end and lifted upwardly to peel the portion of the shingled assembly overlying the strip from the locating elements.

Abstract: Looseleaf notebooks, presentation devices and similar stationery items incorporating a binder mechanism attached to the side of the rear cover. Three slots are present along the side of the front cover positioned so as to fit into the ring binder mechanism to lock the notebook and secure all contents. The ring binder itself may contain a stiff paper or plastic insert for providing additional support for use as a presentation device. Such insert may includes three projections along the bottom manufactured to fit into the front cover slots to convert the notebook into an easel stand. The stiff insert additionally may function as the third side during vertical positioning of the notebook thereby allowing for a stable free standing presentation device.
