Patent ID: 8118513

Claim:
A binder lock mechanism, comprising a manually adjustable locking bar and pair-wise mutually overlappable locking-hook parts co-operative with the locking bar, wherein the pair-wise mutually overlappable locking-hook parts project from a respective binder end half, are connected with the same, 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 include openings adapted to receive respective lock levers connected with the locking bar; in an assembled state, the pair-wise mutually overlappable locking hook parts permanently receive in the openings respective lock levers on a common binder end half; 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 locking 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 a binder end; wherein the pair-wise mutually overlappable locking-hook parts and the locking bar are a plastic material; the locking bar is resilient and has, on an underside thereof, a lever portion applicable against the binder end; the counter-directed resilient tongue is situated on the underside of the locking bar facing the binder end and has, at an outer end thereof, a gripping part for abutment against a counter-stopper of the binder; and the locking bar has a narrowed portion in an area between a lower-situated opening actuation button of the locking bar and a deflected abutment portion, and forms a joint of the locking bar that allows the actuation button to be turned around a stopper at the same time as the other part of the locking bar is actuated to be displaced in a longitudinal direction thereof so as to maneuver the lock levers.
