Abstract: A binder lock mechanism includes a manually adjustable locking bar and co-operative locking-hook parts. Pair-wise mutually overlappable locking-hook parts are connected with and project from a respective binder end half, and are situated at mutual distances from each other. The binder end halves are connected by an intermediate pivot joint. The pair-wise mutually overlappable locking-hook parts present openings adapted to receive a respective lock lever connected with the locking bar and have a respective lock lever permanently received on a common binder end half in a mating opening in an assembled state. The lock levers are arranged at a tip portion and at a waved part, respectively, of the locking bar in such a way that they are situated on a common line through the bar, which is retained by a counter-directed resilient tongue situated on the locking bar and a stopper and co-operatable counter-stoppers situated on the binder end.

Abstract: A device for fastening labels to binders which exhibit slots arranged in pairs at a mutual distance from each other for receiving end sections of label holders, and for firmly locking the end sections in the slots. The label holder is pocket-shaped, is flexible, and exhibits rows of recesses along lateral edge sections opposing each other. Hook-shaped locking elements distributed in rows are received inside the slots. The row of recesses and locking forms formed are adapted to each other in terms of shape for lockable receiving, interacting in pairs, of the respective locking elements in a suitable recess after insertion of the respective label end sections in a suitable slot.

Abstract: A device for fastening prongs in binders, where the prongs are secured to a prong plate arranged to be fastened to the inner sections of a binder spine. Fastening mechanisms are arranged in rows along the binder spine sections. The fastening mechanisms are releasably connectable to supplementary fastening devices located on the respective prong plates. A device for fastening binder sides is also disclosed.

Abstract: The invention relates to a binder lock mechanism (1) that comprises a manually adjustable locking bar (2) and locking-hook parts (3-6) co-operatable with said bar (2). Pair-wise mutually overlapable locking-hook parts, projecting from a respective binder end half (8, 9), connected with the same, and situated at mutual distances from each other—said binder end halves being connected by an intermediate pivot joint (7)—present openings (10, 11) adapted to receive a respective lock lever (12, 13) connected with the locking bar (2) and have a respective lock lever (12, 13) permanently received on the common binder end half (9) in the mating opening (11).

Abstract: The invention relates to an arrangement (1) for a locking mechanism (2) for a binder (3), which comprises a locking rail (5) that is detachably interconnectable with a number of hooks (4), which rail is capable of displacement by means of a manually actuated, spring-operated locking button (6).
