Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper holding structure mainly used for a binder, which is easy to manufacture and easy to use.

[0002]

2. Description of the Related Art In a conventional paper pressing structure for a binder, a metal paper pressing plate is used, and two spring rods are arranged in a longitudinal direction while sandwiching a fixed rod. The middle part of the spring bar is rotated by a turning plate with a tab to widen the facing interval of the spring bar in the central part, and the ends of the spring bar press the fixed bar to press the paper holding plate. The state was fixed.

On the contrary, when the rotating plate is turned to release the pressing force of the spring end, the paper pressing plate is pulled up, moved to the curved rod on the opposite side, and the curved rod is tilted to take in and out the paper. Was adopted.

Such a conventional paper pressing plate is made of metal, and the structure for mounting the spring rod and the rotating plate is troublesome, and rust-proof plating is also required. Therefore, the manufacturing cost is high and the cost is high.

The present invention focuses on the use of a synthetic resin for the rotary plate, which eliminates the need for a spring rod, a rotary plate, etc., facilitates manufacturing, is inexpensive, and ensures that the paper-pressed state is fixed and maintained. It is a technical challenge to provide a paper holding structure.

[0006]

The gist of the present invention will be described with reference to the accompanying drawings.

[0007] Two fixed rods 1 and 2, which are erected at a predetermined interval, and abutting tips 3'and 4'which are abutted on the tops 1'and 2'of the fixed rods 1 and 2 are provided. The curved rods 3 and 4 are fixed to the tops 1 ′ and 2 ′ of the fixed rods 1 and 2 and the curved rods 3
The curved rods 3 and 4 are provided so as to be able to rise and fall such that the abutting tip portions 3 ′ and 4 ′ of 4 are butted against each other, and are formed by the fixed rods 1 and 2 and the curved rods 3 and 4. A pair of right and left inverted U-shaped paper threading rings a, a and 6 are inserted with the paper sheets 6 having the fastening holes 5 stacked one after another, and the uppermost part thereof is attached to the paper threading rings a, a. A paper pressing mechanism that presses the paper with the paper pressing plate b and fixes the pressed state.
Is provided, and one end portion of the long guide windows 7 and 8 is fixed to the fixed rods 1 and 2.
The width is slightly wider than the diameter of the other end, and the other end is made slightly narrower to form tapered edges 9 and 10. The present invention relates to a paper pressing structure characterized in that the paper pressing plate b is configured to be fixed in the paper pressing state by moving the material in a narrow direction by the pressing elasticity of the material.

The paper holding structure according to claim 1, wherein the guide long windows 7 and 8 of the paper holding plate b are arranged in a direction orthogonal to the length direction of the paper holding plate b. It is a thing.

Further, the engaging edges 18 of the projections and depressions of the guide long windows 7 and 8 of the paper pressing plate b are formed on the tapered edges 9 and 10 of the paper-pressing plate b. It is related to the paper holding structure.

Further, an opening 11 or 12 for adding locking elasticity is additionally provided inside the long guide window 7 or 8 of the paper pressing plate b. The present invention relates to the paper pressing structure described.

[0011]

The paper pressing plate b is moved to the side of the curved rods 3 and 4, and the curved rods 3 and 4 are tilted outward to open the abutting tip portions 3'and 4'of the paper threading rings a and a. The paper 6 is fitted into the fixed rods 1 and 2 by the fastening holes 5 arranged side by side at the edges. Then the curved rod 3
A guide for moving the paper pressing plate b to the fixed rods 1 and 2 and pressing the finger to the paper pressing state at the same time, while simultaneously sliding the paper pressing plate b and sliding the paper pressing plate b. When the fixing rods 1 and 2 are positioned on the narrow side of the long windows 7 and 8, the paper pressing plate b is fixed to the paper threading rings a and a by the material elastic force of the tapered edges 9 and 10, and the paper 6 is pressed down. Is maintained.

On the contrary, when the paper is pushed back to the wider side, the paper pressing state is released.

At this time, if the guide long windows 7 and 8 are arranged in a direction orthogonal to the length direction of the paper pressing plate b, the paper pressing plate b is kept horizontal even in the curved portions of the bending rods 3 and 4, and the paper pressing plate b is held. Is done well.

Further, the tapered edges 9 and 10 are provided with concave and convex engaging tooth edges.
Providing 18 makes it possible to more securely fix the paper pressing plate b.

Further, if the openings 11 and 12 are additionally provided to the long guide windows 7 and 8, the left and right edges of the long guide windows 7 and 8 will exert an elastic force, so that the paper pressing state can be reliably fixed. it can.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The drawings show two preferred embodiments of the present invention, and FIGS. 1 to 4 show a first embodiment, which will be described in detail below.

Two fixed rods 1 and 2, which are erected at a predetermined interval, and abutting tip portions 3'and 4'which are abutted on the top portions 1'and 2'of the fixed rods 1 and 2 are provided. The curved rods 3 and 4 are fixed to the tops 1 ′ and 2 ′ of the fixed rods 1 and 2 and the curved rods 3
The curved rods 3 and 4 are provided so as to be able to rise and fall such that the abutting tip portions 3 ′ and 4 ′ of 4 are butted against each other, and are formed by the fixed rods 1 and 2 and the curved rods 3 and 4. A pair of right and left inverted U-shaped paper threading rings a, a and 6 are inserted with the paper sheets 6 having the fastening holes 5 stacked one after another, and the uppermost part thereof is attached to the paper threading rings a, a. A paper pressing mechanism that presses the paper with the paper pressing plate b and fixes the pressed state.
Is provided, and one end portion of the long guide windows 7 and 8 is fixed to the fixed rods 1 and 2.
The width is slightly wider than the diameter of the other end, and the other end is made slightly narrower to form tapered edges 9 and 10. It is configured so that the paper pressing plate b can be fixed in the paper pressing state by the pressing elasticity of the material by moving to the narrower side.

At this time, the guide long windows 7 and 8 of the paper pressing plate b
Are arranged in a direction orthogonal to the length direction of the paper pressing plate b.

Although not shown in the drawing, the present invention can be implemented in the same manner by arranging the long guide windows 7 and 8 in the length direction of the paper pressing plate b and moving the paper pressing plate b in the length direction. There is an advantage that the paper pressing plate b is formed in a strip shape, but if it is provided in the orthogonal direction, the paper pressing of the curved portion is performed horizontally, which is better.

FIG. 5 shows a second embodiment, in which both sides of the tapered edges 9 and 10 have a pitch of about 1.6 mm and a depth of 0.5 m.
Providing an engaging tooth edge 18 with irregularities of about m, the distance from the outer edge is 3 m
m, the width of the openings 11 and 12 (preferably in the form of long windows) is about 2 mm, the distance between the guide long windows 8 and 9 is about 1.5 mm, and the thickness of the paper pressing plate b is about 3 mm. Mass production by resin molding is desirable.

In the figure, reference numeral c is a binder, 13 is a mounting plate, and 14
Is a rotary shaft rod mounted on the curved rods 3 and 4, 15 is a bearing portion, 16 is a rotary pressing spring plate of the rotary shaft rod 14, and 17 is a knob portion for sliding.

[0022]

Since the present invention is configured as described above, the taper edge of the guide long window presses the fixed rod and presses it by simply sliding the paper pressing plate slightly from the paper pressing state.
At that time, the paper pressing plate is fixed by the elastic action of the material, and it becomes an easy-to-use paper pressing plate that can firmly maintain the paper pressing state,
The paper holder structure is simple and inexpensive.
