INVENTOR: LEWIS COHEN INVENTION: RING MECHANISM FOR LOOSE LEAF BINDER ABSTRACT In a ring mechanism for loose leaf binders and the like, it is known to affix one of the ring halves to the bottom of the carrier rail and to provide grooves in the binder cover so that the ring half can lie closely ad- jacent to the binder cover while still permitting the ring halves to be opened. In this invention, the ring element is attached to the top of the carrier rail through an aperture in the cover rail and the cover rail is loosely attached to the binder cover. This permits the ring mechanism of the invention to be manufactured on conventional equipment and eliminates the need for grooves in the binder cover.
