Abstract: The present invention provides a single-detent binder for holding loose-leaf paper sheets, which mainly includes a housing, one pair of symmetrically elongated baseplates, ring shaped components, a control component, and a pull rod. The control component is operable to move the rings for performing the locking and unlocking function. As the handle forms an essential and irreplaceable part of the whole mechanism, embodiments of the present invention disclose a single-detent binder with the control component constructed in a way to improve the durability of the internal components.

Abstract: Binder apparatus are disclosed. An example binder apparatus includes a housing, first and second carrier rails supported by the housing and a slider movable between a first position and a second position. In the first position, the slider to secure the first and second carrier rails in a closed position. In the second position, the slider to enable pivotable movement of the first and second carrier rail. The binder apparatus includes a lever to pivot the first carrier rail and the second carrier rail. The lever includes a groove and a channel. The groove to receive a portion of the first and second carrier rails, the channel to receive an end of the slider. The end of the slider to move within the channel to delay movement of the slider when the lever pivots the first and second carrier rails from the open position toward the closed position.

Abstract: A device for binding sheets in a pack, the device having a flat rectangular sheet element (3) in turn having, along one major side (3a), a number of flexible tongues (7) arranged combfashion; and a closing strip (10) extending along the major side (3a). The strip (10) has an application surface (13) facing the tongues (7) and having a layer of adhesive (17). The flat element (3) is placeable on a first face of the pack, with the tongues (7) inserted inside the respective holes (33) formed along one edge of the pack, and with respective ends (7e) of the tongues (7) projecting from the holes. The closing strip (10) is foldable and placeable with the layer of adhesive (17) superimposed on a flat element (30b) defining a second face of the pack (30).

Abstract: The invention concerns a ring binder mechanism for receiving loose, holed written materials. The ring binder mechanism includes a housing (10) having spring-elastic housing flanks (28) which can be urged open. Two carrier rails (20) are provided in the housing, which are pivotable along their facing longitudinal edges in the manner of a knee-joint against the spring effect of the housing flanks (28). At least two half-rings (16) are provided longitudinally spaced apart and rigidly connected with each of the carrier rails (20), and which pairwise form a ring (14).

Abstract: A sliding clamp for fastening the binding prongs of a binder having flexible binding prongs, which is adapted to slide in a rail-shaped member of substantially U-shaped cross-section, which is fitted with openings for the passage of the binding prongs, wherein the sliding clamp comprises a first elongate portion adapted to slide in the rail-shaped member and which is provided with a passage for a binding prong; and a second portion pivotally connected to the first portion, the second portion being adapted for pivotal movement in a pivoting line extending transversely to the longitudinal direction of the first portion, and that there are provided cam means for being locked in a position wherein the binding prong is bent and clamped.

Abstract: A binder strip for binding loose leaves having perforations therein through which flexible wires can be inserted. The binder strip comprises a substantially U-shaped rail having holes in its bottom surface for the passage of said wires, and the rail is provided at least at one end with a clamping member pivotally connected to the rail and in operative position accommodated by the rail for the clamping down a wire, said clamping member being formed in one integral part with said rail and with a flexible bridge member joining said rail and said clamping member and providing for pivoting action.

Abstract: A first plastic strip has longitudinally spaced studs each of which can be bent over at a 90.degree. angle, the studs being serrated. A second strip has holes through which the studs fit and grooves which receive and secure the bent over studs, the grooves being serrated. Paper punched to receive the studs is clamped between the two strips. The studs are then bent over into grooves in the second strip and held in bent position in part by said teeth intermeshing. The paper is thus securely bound.

Abstract: A data binder having compression bars forming longitudinal rails and a center channel, flexible posts securing data sheets between compression bars and a retaining slide member embracing the rails to hold the bent over posts in place. Each end of said retaining slide member includes a flare at the end of the center groove for receiving the post. The guide groove facilitates insertion of the post into the retaining slide member.
