Ring binder sheet positioner

A sheet positioner assembly for a sheet binder comprising:

• a first binder ring comprising a first arcuate segment, a second arcuate segment movable away from said first arcuate segment for opening said first ring for receiving a sheet on one of the first and second segments by a hole in the sheet, and movable toward said first arcuate segment for closing said ring at a first junction, a second ring parallel to and spaced from said first ring, comprising a third segment, a ring operating mechanism cover having a length, from which lower portions of the first, second and third segments protrude, a first line in a plane of said first ring that extends through a portion of the ring that exhibits a wide horizontal of closed ring, a first longitudinal wall, a second longitudinal wall, a third wall connecting said first wall to said second wall forming a longitudinal channel, a first hole through said first wall, a second hole through said second wall, an axis through the first and second holes that is transverse to the longitudinal axis of said channel, each hole of the first and second holes being large enough to receive a segment of said first ring, said channel being on one of the first and second segments, said channel being elastic so that said first and second walls resile laterally so that said channel locks on the segment by said first and second holes when said channel is left unattended.

A sheet positioner for supporting a sheet on a sheet binder ring comprising a binder cover, a first arcuate segment and a second arcuate segment movable away from the first arcuate segment for opening the ring for receiving a sheet on one of the first and second segments by a hole in the sheet, and movable toward the first arcuate segment for closing the ring at a first junction, a ring operating mechanism cover from which lower portions of the first and second segments protrude, a binder cover hingedly connected to the ring operating mechanism cover, said sheet positioner comprising:

• a panel having a length, a first end, a second end, and comprising a first hole through said panel, a second hole through said panel spaced from said first hole, the spacing of the holes from each other and the length being such that when said panel is mounted on one of the lower portions through the first and second holes and the ring is closed, said panel arcs from said first end being in the ring adjacent to said operating mechanism cover, to being outside the ring below a line in a plane of the ring that extends through a portion of the ring that exhibits a wide horizontal of closed ring, to said second end being in the ring above said first end for pivoting a sheet on said second end when the sheet is mounted on the ring on said panel and the sheet is moved toward the junction by the binder cover.
