摘要： The present loose leaf binder consists of two main sections each provided with spaced half rings and held together by means of metal links or a length of suitably bent metal wire. Between the two main sections of the binder there is an elongated strip selectively movable to open and close complementary pairs of the binder half rings. The free ends of the complementary pairs of half rings are duly fitted with protruding extensions which overlap when the binder is closed.

摘要： 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.

摘要： 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.
