Abstract
The invention relates to a unitary spine binder for securing a stack of sheets, which comprises a dorsal part (3, 4, 5) from which spaced fingers (1, 11) extend to form loops. The individual fingers are arranged in two sections (1, 11) lying opposite one another on this dorsal part (3, 4), the dorsal part (3, 4, 5) forming a hinge between the finger sections (1, 11). The end (12) of at least one of the first finger elements (1) remote from its dorsal part is equipped with a push button (7); the end (22) of the second finger element (11) remote from its dorsal part and lying opposite the first finger element is equipped with an opening (10) essentially complementary to the push button (7), and which is adapted to receive the push button (7). In this way, a simple spine binder is created which does not require the use of additional binding devices. Sheets can be removed from the spine binder or newly inserted into it.
