Abstract: A ring binder, with a fixed bar (1), bearing hooks (2) and a moving bar (3), wherein the fixed bar (1) is immovably fixed on a spine plate of a folder; the bearing hooks (2) are fixed on the upper surface of the fixed bar (1); the moving bar (3) is movably lapped over one side of the fixed bar (1); the lower surface of the moving bar (3) and the lower surface of the fixed bar (1) are clamped and connected with each other; the moving bar (3) can rotate relative to the fixed bar (1) and slide along the length direction of the fixed bar (1); a spring (4) connected between the moving bar (3) and the fixed bar (1); and moving shackles (5) fixed on the upper surface of the moving bar (3). As the ring binder lacks a base plate, a housing, etc., both the opening and the closing of the binder are convenient and the cost of the ring binder is reduced.

Abstract: Binder apparatus are described. An example binder apparatus includes a housing, a first support rail positioned within the housing and a second support rail positioned within the housing. The binder apparatus also includes first and second closure members coupled to the respective support rails. The closure members are positioned on the respective support rails to enable locking elements of the closure members to interlock when the binder apparatus is in a closed position. The binder apparatus also includes a lever comprising tabs that are received by recesses defined by the support rails. An interaction between the tabs and the support rails enables the support rails to be moved relative to one another and the locking elements to be moved to an unlocked position.

Abstract: A binder for receiving and retaining papers includes first and second strips slidably connected to one another. Each strip includes spaced-apart fingers extending upwardly therefrom. The fingers of the first and second strips are offset from one another when the first and second strips are in a closed position. The first and second strips include releasable locking catches to retain the strips in a closed position, and release tabs for selectively moving the second strip into the open position. A cover having living hinges is attached to a lower surface of the first strip. The cover may include pockets on an outer surface thereof for accepting inserts, such as file hangers or printed labels.

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 binding assembly includes first and second sheet retaining members which are releasably attached to a base member by first and second latching mechanisms. The sheet retaining members include a pair of side members which support a pair of pins and tubes onto which sheets of paper or other materials are placed. Each of the side members includes an engaging rod which is receivable in a channel provided in the base member to retain the sheet retaining members to the base member. Each of the latching mechanisms are independently pivotable about an axis perpendicular to the pins and tubes from a retaining position where the sheet retaining members are constrained to the base member, to a releasing position where the sheet retaining members may be detached from the base member.

Abstract: A binder locking clip (100) used with a binder metal (10) having a locking member (50) with a slot (62) formed therein. The clip has a first leg (102) and a second leg (104). The legs are spaced apart from each other and one of the legs has a detent (106) formed in it. The detent fits in the slot and engages a post (56) with respect to which the slot is movable when the locking member is moved. The clip engages the post when the frame member is moved in a direction by which the binder metal can be opened to prevent movement of the locking member in that direction.

Abstract: An expandable capacity album or binder for storing and displaying artwork or photographs retains the appearance of a library bound hardcover book at any state of expansion. The front cover and back cover are hinged to a spine which has page retaining channels that allow looseleaf pages to be inserted into or removed from the album. Together, the spine and the channels are adjustable so that the album will expand and contract for different capacities. The outside of the album is covered with leather or cloth to give the album the appearance of a library bound hardcover book. In between the spine and the covering is a resilient material such as plastic foam which can compress or expand so that the covering will always look properly fitted to the spine even when the spine is expanded or contracted to change the capacity of the album. In this way the album maintains its library bound appearance at any state of expansion.

Abstract: This album with interchangeable sheets has coupling elements for the sheets which are preferably made of plastics, are fixed on the inner side of the rear cover and can be opened after extracting closure profiled elements which are mutually aligned and are parallel to the spine of the binder. The sheets may easily be turned since they have slots which are particularly enlarged with respect to the cross section of the coupling elements. Furthermore a perfect alignment of the sheets is obtained in a very simple and original manner, by virtue of raised portions which also protrude from the inner side of the rear cover and act against an appropriately shaped inner edge of the sheets.

Abstract: A binder for attaching separate leaves together in a non-permanent fashion. The binder comprises a scarfing section, a clamping section, and tenons. Each binder is attachable to additional binders such that the number of leaves held together by the device is adjustable, and is virtually unlimited.

Abstract: A ring-type binder for retaining loose-leaf sheets of paper is disclosed. The binder has base and top members which are slidably secured to each other. Mounted to each of these members along and projecting from an edge are a plurality of half-ring members. With this configuration the base and top members can be slid between an open position and a closed position in which the half-rings of the top member are mated with the half-rings of the base member.

Abstract: A loose leaf binder is formed from three parts assembled in a manner providing a binder of minimum thickness.

Abstract: An arrangement is provided for retaining loose sheets of paper. A pair of sheet retaining components, each having a plurality of half loops, are hingedly held together by wire clips. An actuator is interposed between the sheet containing components. The actuator is provided with inclined slots which, when the actuator is displaced, engage and move the clips causing one sheet retaining component to move with respect to the other to unlock the engaged ends of the respective half loops. Once unlocked, the sheet retaining components can be hinged apart to permit removal and/or addition of loose leaf paper. Means are provided to retain the actuator in proper and secure operative position between the sheet retaining components.

Abstract: A loose leaf binder is formed from two main parts, which have cooperating half-rings and are interconnected by wire links. The cooperating half-rings of the binder have a mating locking mechanism at their free ends.The binder's opening is achieved through relative displacement, in longitudinal and transverse directions, of its main parts. A movable clip, placed at an end of the binder, prevents the relative displacement of the main parts when the binder is closed.

Abstract: The present invention relates to a binding mechanism for loose-leaf binder comprising, mounted on a support, at least two rings each constituted by a fixed vertical receiver pin, the upper end of which is hollow, a fixed, vertical, tubular hoop-guide and a movable hoop-shaped member engaged, in closed position, in the upper end of the pin and slidable vertically in the hoop-guide and pivoting in a plane parallel to the plane of the leaves, to come to open position. The simultaneous control of the movement of the hoops is effected by a slide provided with ramps, the lower ends of the hoops being engaged both in fixed ramps fast with the support and in the ramps for controlling the slide. The invention is particularly applicable to binders or folders for perforated leaves.
