Description

DEVICE FOR RETAINING A STACK OF PAPERS IN A FILE}

The present invention is intended to preserve a pile of paper in piles in such a way that the papers are preserved by rings opened and closed by a mechanism comprising a lever, such as a lever arch mechanism for a lever arch pile. Relates to a device.

Lever arch files for keeping paper stacks in files are well known. The lever arch piles generally include two rings fixed upwardly and secured to the base to engage holes formed in the margin of the base, paper stack. Each ring consists of a columnar portion and an arcuate portion for holding the papers when the pile is closed. A mechanism is provided to keep these parts in the closed position, in which the rings retain the stacks of paper so that the top page (s) in the stack slide along the ring so that the lower pages can be read. Form them. This mechanism can be operated to separate the two parts so that papers can be added or removed from the rings by the lever. The lever can also be operated to move the two parts together back to the closed position.

The levers of the mechanism are made of metal because of the need for strength, especially in the area of the lever that engages the rest of the mechanism for opening and closing the rings, but metal can be inconvenient for those who frequently use these piles. Moreover, there was no means of coding color into the mechanism so that the mechanism could be easily distinguished without painting that could be easily peeled off.

The present invention provides a method that allows frequent users to open and close the mechanism more comfortably, and also to color the mechanisms and, incidentally, to make the mechanism better.

According to a first aspect of the invention:

Base;

At least two rings fixed upwardly to the base to engage the margin holes of the paper, the ring consisting of a movable first portion and a second portion and aligned to engage holes in the margins of the paper;

In a closed position in which the first and second portions of each ring are adjacent to each other to form a closed loop and in an open position in which the first and second portions of each ring are spaced from each other so that papers can be added to or removed from the rings. A mechanism for holding the first and second portions of each ring in either position, comprising a lever having a handle end and an actuation end, the actuating end placing the first and second parts of each ring between the open and closed positions. A device for preserving a pile of paper with holes in the margin that includes a mechanism formed of a material softer than metal, preferably plastic, in cooperation with the rest of the mechanism for movement in the lever Is provided.

As used herein, the term "ring" refers to:

a) an apparatus in which the first and second portions are each partially circular, and

b) a device in which the first and second portions together form a long elongated loop in which one portion (although may have a bend along the longitudinal direction) is generally straight and the other portion has an arch-shaped top (so-called "lever arch File ").

However, the specific shape of the rings does not affect the principle behind the present invention, and the rings may have any shape needed.

Preferably, as generally known in the so-called "lever arch piles", the first portions of each ring are connected to each other and rotatably mounted to the base and the lever is adapted to move the first portions between the open and closed positions. Works. It may include a spring that pushes the first portions of the rings to an open position when the lever is released, in which case the lever operates by moving the first portions to the closed position against the action of the spring. The first parts may be locked in the closed position by the lever until the levers are released, that is, they can move to the open position under the influence of the spring. Other methods are also possible, ie the spring may push the first parts to the closed position and the lever may act to move the first parts to the open position against the action of the spring. However, such a device is undesirable because the rings are held in the closed position only by the springs so that the rings can be opened accidentally.                 

The handle end may be entirely formed of a soft material, or otherwise only the sleeve of the lever, which is metallic, may be a soft material. If the handle end of the lever is made of plastic or other colorable material, the handle end may be color coded by the user depending on the contents of the file. This also makes the mechanism more attractive.

Three embodiments of the invention will be described, by way of example only, with reference to the accompanying drawings, in which:

9 is an exploded view of the device shown in FIG. 7;

Referring first to FIGS. 1A and 6, an apparatus for storing paper stacks in a file is shown. The device comprises a base 10 made of pressed steel and having holes 12 for receiving rivets (not shown) for securing the device to a pile. Two rings 14 extending from the base 10 are each comprised of a fixed column 16 and a movable arch portion 18. The pillars 16 pass through the holes 19 of the base 10 (see FIG. 6) and are held in place by deforming the base of the pillar with a hammer.

The arch portions 18 of the two rings 14 are joined together by a central portion 30, the central portion being two bent over tabs 31 pressed out from the base 10; 6) is rotatably held at the base. This arrangement allows the arch portion 18 and the connection 30 to be rotated about a horizontal axis 25 extending between the two tabs 31.

The connecting portion 18 comprises a crank portion 32. Leaf spring 34 has one end 34 'secured to slot 36 of the base; The other end 34 ″ engages below the crank portion 32 to push the crank portion 32 upwards such that the arch portions 18 rotate counterclockwise about the horizontal axis 25.

In addition, generally upstanding walls 40 are pressed from the base 10. The lever 42 is secured to the wall 40 by means of rivets 44 penetrating the holes 46 of the wall 40 and the holes 48 of the lever 42. The device is such that the rivet 44 allows the lever 42 to rotate about the wall 40.

The lever 42 has a roller 50 whose end is fixed to the lever by another rivet 52 fixed to the hole 54 of the lever 42. As described below, the roller is coupled to the top of the crank portion 32 to control the opening and closing of the arch portion 14 of the ring 14.

The upper ends of the pillars 16 have a male shape 60 which mates with a corresponding female shape (see FIG. 6) at the end 62 of the arch portion 18; This allows for positive engagement between the pillar 16 and the arch portion 18 of each of the rings 14 and assists the alignment between the pillar 16 and the arch portion 18 of the respective rings 14 so that the paper can be placed therebetween. Do not tear at the joints.

The lever 42 can be moved about the rivet 44 between a horizontal position (shown in FIG. 1) and an upwardly extending position (not shown). In the position shown in FIG. 1, the roller 50 is pressed against the corresponding pillars 16 to press down the crank portion 32 against the action of the spring 34 to form the closed ring shown in FIG. 1. Hold the arch portion 18 of each ring in the adjacent locked position.

The roller 50 of the lever passes through the dead center of the lever mechanism when fully moved to the downward position, whereby the spring 34 acts to keep the lever in the closed position.

When the lever 42 is moved upwards from the position shown in FIG. 1, the roller 50 no longer presses the crank portion 32 down, which causes the crank portion 32 to be driven by the spring 34. Allowing upward movement allows the arch portion 18 to rotate counterclockwise about the axis 25 to separate the arch portions 18 of the rings from the pillar portions 16. By pressing the lever 42 downward, the crank portion 32 can be moved by the roller 50 to the closed position shown in FIG. 1 against the action of the spring 34.

A paper stack (not shown) with holes in the margins may fit into the pillars when the rings are in the "open" position. Once the paper stack is fitted into the pillars 16, the lever 42 can be pressed into the position shown in FIG. 1 to hold the paper stack mooring to the rings 14. The upper pages of the pile can slide along the pillars 16 and retained in the arch portion 18 so that the papers below the pile can be exposed for easy reading. The lever arch file described above is conventional.

The lever 42 has a roller 50 and a metal working end 45 fixed to the wall 40. The lever also has a handle end 47 which is operated by the user. The operating end 45 has a spigot 49 fitted into the recess 51 of the handle end 47, and the handle end is held in the spigot by friction or adhesive.
