Problems solved by technology

[0003] This conventional folder device is inconvenient to use because when the lever is pivoted upwards to open the ring, the lever is very close to or even touches one of the arches, making it impossible to insert paper into the arches or Paper is removed from the arch

Embodiment Construction

[0034] figure 1 Shown are components of a paper retaining device according to a first embodiment of the present invention, wherein the device is generally designated 100 . Apparatus 100 includes a generally flat base 102 to which are fixedly secured two posts 104 . A pair of arches 106 are connected to each other by curved rods 108 , and the pair of arches 106 are integrally formed by curved rods 108 . Thus, the arch 106 and the curved rod 108 are able to move simultaneously.

[0035] The curved rod 108 engages a pair of clamps 110 that are located on and integrally formed with the base 102 such that the curved rod 108 can be positioned about the axis R of the proximal base 102 relative to the base 102 and the post 104 1 -R 1 pivot. With this arrangement, the curved lever 108 can pivot so that the arch 106 pivots between a ring closed position (the arch 106 and the curved lever 108 can move simultaneously) and a ring open position in which the arch 106 The free end 106a o...

Abstract

A paper-retaining mechanism (100,200) includes a base (102,202), two posts (104,204) fixed to the base, two arches (106,206) engaged with the base for pivotal movement relative to the posts, and a lever (114,214) pivotable relative to the base. The arches are joined with each other via a cranked rod (108,208) for simultaneous movement, and are pivotable between a 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 posts whereby the rings are open. The lever is pivotable relative to the base between a first position in which the rings are closed and a second position in which the rings are open, and the lever includes a toe portion (126,226) which pivots the cranked rod away from thebase to pivot the arches to the open position when the lever is pivoted from the first position to the second position.

Description

technical field [0001] The present invention relates to a paper holding device and a folder including the paper holding device. Background technique [0002] There are various paper retaining devices. In one conventional paper retaining device, commonly referred to as a lever-arch folder device, a single-armed lever is pivotable to pivot a pair of arches relative to a pair of fixed posts, thereby allowing the file to be retrieved from the document. The perforated paper is removed from or inserted into the folder device and used to close the posts and arches to form a pair of closed loops for retaining the paper therein. The pair of arches are connected by an intermediate crank on which a roller connected to the lever moves when the lever is pivotally moved so as to open or close the pair of rings. In operation of this traditional folder device, the lever pivots downward, closing the pair of loops formed by the posts and arches; the lever pivots upward, allowing the reed to...
