A ring binder mechanism has at least two semi-ring pairs, which are arranged spaced apart from one another and which each consist of two semi-rings (20, 20′), the semi-rings (20) of a first group and the semi-rings (20′) of a second group being rigidly connected to one another in a grouped manner in the area of their roots and thereby kept spaced apart from one another. Mutually complementary locking bar elements (44, 44′), which, in the closed position, are locked to prevent pivoting of the semi-rings relative to one another, are arranged at the ends of the semi-rings (20, 20′) of at least one of the semi-ring pairs. In a free position, the semi-rings (20, 20′) allocated in pairs span a common radial plane (46), and the locking bar elements (44, 44′) thereof are spaced radially apart from one another, and in the locked position, the locking bar elements (44, 44′) are coupled to one another with a form fit in all directions within the tangential plane (48) of the rings (18) which intersects the locking bar elements (44, 44′) and is perpendicular to the radial plane (46). |

1. A ring binder mechanism
1.1 having at least two half-ring pairs,
1.1.1 which are arranged spaced apart from one another,1.1.2 and which each consist of two half-rings (20, 20′), 1.2 wherein the half-rings (20) of a first group and the half-rings (20′) of a second group
1.2.1 are rigidly connected to one another in a grouped manner in the region of their roots (24, 24′) and thereby kept apart from one another,1.2.2 said half-rings complementing one another in pairs to form the half-ring pairs,1.2.3 and being able to be pivoted together relative to the respective other group between an open position opening up an insert gap (43) between their free ends and a closed position, complementing one another to form one respective closed ring (18), 1.3 wherein at the ends of the half-rings (20, 20′) of at least one of the half-ring pairs
1.3.1 mutually complementary1.3.2 locking bar elements (44, 44′) are arranged, said locking bar elements being locked together in the closed position to prevent pivoting of the half-rings (20, 20′), 1.4 wherein at the start of an opening procedure at least one of the half-rings (20) of the half-ring pairs is able to be moved relative to the other half-ring (20′) by initiating an unlocking procedure between a locked position and a released position of the associated locking bar elements (44, 44′), 1.5 wherein during the course of a locking procedure at least one of the half-rings (20) of the half-ring pairs is able to be moved relative to the other half-ring (20′) between the released position and the locked position of the associated locking bar elements (44, 44′), 1.6 and wherein in the locked position the half-rings (20, 20′) associated with one another in pairs span a common radial plane (46) and the locking bar elements (44, 44′) thereof are positively coupled together at least in the opening direction of the half-rings (20, 20′), 1.7 wherein in the released position, the half-rings (20, 20′) associated with one another in pairs, span a common radial plane (42) and the locking bar elements (44, 44′) thereof are radially spaced apart from one another 1.8 and wherein in the locked position, the locking bar elements (44, 44′) are positively coupled together in all directions within the tangential plane (48) of the rings (18) which is perpendicular to the radial plane (46) and which intersects the locking bar elements (44, 44′). |
