Problems solved by technology

[0003] The problem with this conventional lever-arch type file mechanism is that when the lever is pivoted to the upper position to open the ring, the lever is in contact with the underside of one of the arches or at least very close, so paper can only be inserted into or removed from the cylinder, not the arch

Embodiment Construction

[0036] The paper holding mechanism according to the first embodiment of the present invention is shown in Figure 1 to Figure 15 , usually marked as 100. The mechanism 100 has a substantially planar base 102 on which two cylindrical elements 104 are fixedly connected. A pair of arches 106 are interconnected by curved rods 108 . Arch 106 is integrally formed with curved rod 108 and moves simultaneously.

[0037] The arch 106 is connected to the base 102 by a pair of clips 110 on the base 102 . Clamp 110 allows arch 106 to pivot relative to column 104 and base 102 between a closed position in which the free end of arch 106 engages and contacts the free end of column 104 and an open position. to form two closed loops (such as Figure 2 to Figure 8 shown), in the open position the free end of the arch 106 is separated from the free end of the column 104 to disengage to open the two rings (as Figure 9 to Figure 15 shown). When the arch 106 is in the open position, some perfo...

Abstract

A paper-retaining mechanism (100, 200) is disclosed as including a base (102, 202); two posts (104, 204) fixed to the base; and two arches (106, 206) movable relative to the base and the posts betweena closed position in which the arches are in contact with the posts to form two closed rings and an open position in which the arches are out of contact with the post members to open the rings; and further including a switch (122, 222) reciprocatable along a straight line between a first position and a second position to selectively move the arches between the closed position and the open position.

Description

technical field [0001] The invention relates to a paper holding mechanism and a document file with the paper holding mechanism. Background technique [0002] Various paper retaining mechanisms are known. In a conventional paper retention mechanism known as a lever-arch type file folder mechanism, a single-armed lever is pivotable so that a pair of arches pivots relative to and away from a pair of fixed columns , allowing some perforated sheets to be removed from or inserted into the folder mechanism, and to allow the arch to pivot toward the column so that the column and arch form a closed pair the loop to hold the paper in it. The pair of arches are connected by an intermediate crank on which a roller attached to the lever moves to open or close the pair of rings as the lever pivots. During operation of this traditional folder mechanism, the lever can be pivoted downward to close the pair of loops formed by the column and arch, or pivoted upward to allow the reed to act ...
