Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a paper leaf presser plate in a paper leaf binder, and is applied to the field of paper leaf binders.

[Conventional technology]

Conventionally, as a paper holding device that presses a group of paper sheets to be bound to the binder ring, a simple paper holding plate was used, which could be easily engaged and disengaged from both rings while bending one sheet holding plate to press and release the group of paper sheets. There was no such structure.

[Problem that the invention attempts to solve]

The present invention is designed to be able to easily engage and disengage from the binder ring, and to securely hold and release paper sheets.In particular, it is made of polypropylene and is strong, so it can be easily engaged and disengaged from the ring. It is provided that the engaging/disengaging operation can be easily performed, and the simple shape made of one piece makes it easy to manufacture and can be suitably implemented.

[Means for solving problems]

Next, embodiments shown in the drawings will be described as means for solving the problems.

B is a paper binder, which is composed of a front surface 5, a shoulder surface 6, and a back surface 7, and a mounting plate 8 attached to the inner end of the back surface 7 has a straight ring rod 2a and a curved ring rod 2b. 4 rings at intervals of 2
two projecting pieces 9 at both ends of the mounting board 8,
9 is rotated outward, each ring rod 2b is installed so that it opens away from the ring rod 2a, and each ring rod 2a is configured so that the side binding hole 10 of each paper sheet C can be inserted into each ring rod 2a. It is constructed in the same way as the shape and structure.

A is a slightly thick polypropylene paper leaf holding plate, with both plate surfaces a1 and a in the center of one elongated plate.
A V-shaped cut-shaped bending edge 1 is formed so that the bending edge 2 can be bent from a plane until the cross section becomes a V-shape, and both adjacent rings 2 of the binder B are fitted on both end sides of one plate surface a1, respectively. Both round holes 3, 3 are formed, and recessed parts 4, 4, which can be engaged with and detached from both rings 2, 2, are slightly slanted at both ends of the other side plate surface a2 corresponding to both round holes 3, 3. However, the double-concave notches 4, 4 open obliquely to both ends with respect to the lateral direction perpendicular to the longitudinal direction of the entire plate, and the double-concave notches 4, 4 open diagonally to both ends. The edges 4a, 4a of the extending plate surface a2 are formed to be lower than the edges 4b of the plate surface a2 extending inward from the double concave notches 4, 4.

[Effect]

Therefore, when binding or unbinding paper sheets C group, each ring rod 2b is opened and inserted into each ring rod 2a as in the conventional method, as shown in FIG.
When attaching the paper sheet holding plate A to a group of a certain amount of paper sheets C, as shown in FIG.
The ring can be attached by closing the ring rods 2b, 2b as shown in FIG.

With one plate surface a1 in pressure contact with the upper surface of the group of paper sheets C, the other plate surface a2 is bent from the bending edge 1 and rotated in the direction of the ring rods 2a, 2a so that the cross section becomes U-shaped. When the double concave notches 4, 4 are pushed into the ring rods 2a, 2a while pressing the concave notches 4, 4, since the concave notches 4, 4 are formed diagonally, the plate surface a2 is pushed as shown in FIGS. 1 to 3. The sides are inclined with respect to the ring rods 2a, 2a, so that they can be strongly engaged, and a paper presser is formed.

In addition, when removing the ring rods 2a, 2, when the plate surface a2 is strongly rotated inward, the recessed portions 4, 4 are removed from the ring rods 2a, 2.
It will deviate from a.

[Effect of idea]

In this way, the present invention forms a bending edge 1 in the center of a long and thin plate made of polypropylene so that both plate surfaces a1 and a2 can be bent from a plane until the cross section becomes V-shaped, and one plate surface Both round holes 3, 3 that can fit into both adjacent rings 2, 2 of binder B are formed on both ends of a1, and both ends of the other side plate surface a2 corresponding to both round holes 3, 3 are formed on both ends of a1. ring 2,
Since the recesses 4, 4, which can be engaged and detached from the holes 3 and 2, are formed slightly diagonally, the holes 3,
3 is fitted into the rings 2, 2, and with the plate surface a1 in pressure contact with the upper surface of the sheet group, rotate the other plate surface a2 toward the rings 2, 2 so that the cross section becomes V-shaped. To easily set a sheet pressing plate A by simply engaging concave notches 4, 4 with rings 2, 2, and to easily release it by simply rotating it based on the plate surface a2. This paper sheet holding plate A is made of polypropylene and is strong, and the recessed parts 4, 4 are slightly slanted, so that it can be securely engaged with the rings 2, 2, and can be easily disengaged and engaged. It is easy to release the bond, and the simple shape made of one piece makes it easy to manufacture, and has the advantage of being suitable for implementation.
