Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a sheet binding tool used for files, etc., and more specifically, the invention relates to a sheet binding tool used for files, etc., and more specifically, it is used for binding sheets in which a binding arm is provided at the base to be inserted into the binding hole of the sheet. This invention relates to a sheet binding tool that can be easily removed.

[Prior Art] The conventional sheet binding device as described above has a binding arm movably provided at the base so that it can be opened to insert the binding end side of the sheet, has a large number of parts, and has a poor structure. Not only is it complicated and expensive to manufacture, but it also has the disadvantage that if the file is dropped, the impact may cause the binding arm to open and the sheet to come off.

[Purpose of the invention] The present invention was made in order to eliminate the drawbacks of the conventional binding device as mentioned above. The purpose of this invention is to provide a sheet binding tool that does not cause

[Structure of the invention] The present invention includes a rigid base, a rigid binding arm that is integrally provided on the base and has a cutout part for inserting the binding end side of the sheet, and is inserted into the binding hole of the sheet. , closing the defective part of the binding arm, one end being fixed to the base or the defective end of the binding arm, the other end being able to leave contact with the binding arm to receive the binding end side of the sheet, and binding. The main body of the binding device is made up of an elastic tongue that covers the direction in which the loaded sheets come off, and the tongue opening tool is used to separate the plurality of tongues of the binding arm from contact with the binding arm. The present invention is a sheet binding device characterized by the following, and with this configuration, the above object is achieved.

[Example] Hereinafter, the present invention will be explained with reference to illustrated examples.

1 and 2 are side views of a file showing an example of the sheet binding device of the present invention, and FIG. 3 is a perspective view showing an example of a tongue opening device used in the sheet binding device of the present invention.

In the figure, 1 is the rigid base of the sheet binding tool;
2 and 2' are rigid binding arms provided integrally with the base 1, 3 is a defective part, and 4 is an elastic tongue piece for closing the defective part 3. The tongue piece 4 in FIG. 1 has one end fixed to the base 1. One end of the tongue piece 4 shown in FIG. 2 is fixed to the defective part of the binding arm 2'. The base 1 is attached to the inside of the spine 6a of the file cover 6 by rivets 5.

To bind sheets to the sheet binding tool described above, press the tongue piece 4 on the binding end side where the binding holes of the sheet are located and bend it inward from the solid line position to the dotted line position as shown by the arrow, thereby opening the sheet. This is done by inserting the binding end of the sheet from the defective part 3 into the binding arm 2 and inserting the binding arm 2 through the binding hole of the sheet. That is, the elasticity of the tongue piece 4 is preferably such that when it is pushed by the binding end side of the sheet, it bends and the free end side that is in contact with the defective end of the binding arm 2 separates, but the present invention is not limited to this. If you are binding less than a few sheets with no elasticity,
It also includes one in which the tongue piece 4 can be bent using a finger or a tongue piece opening tool 7, which will be described later.

To remove the sheet from the sheet binding tool, bend the tongue piece 4 inward with your fingers or the tongue piece opening tool 7, etc., pull out the binding end of the sheet from the opened defect, and remove the sheet from the binding arm 2. This is done by removing the binding holes. Of course, if the sheets are not to be bound again, the binding holes may be torn to remove them.

If the sheet binding tool has two binding arms 2', 2, it is possible to bend the tongue piece 4 with your fingers without much difficulty when removing or binding the sheets. If the binding arms 2', 2 are provided at three or more locations, it is very difficult to remove or bind the sheets by bending the tongue piece 4 with one's fingers. In that case, for example, a flat plate such as a 30 cm ruler may be used to press and bend the tongue 4 in one step, or a tongue opening tool 7 as shown in FIG. 3 may be used.

The tongue piece opening tool 7 shown in Fig. 3 is used for binding sheets with four binding holes, and the tongue piece opening tool 7 is used by pressing the tongue piece 4 with the side 7b on the opposite side to the side where the holes 7a are provided. It is bent inward and slid into the inside of the binding arm 2 from the side 7b, then the binding arm 2 is inserted through the hole 7a, and then brought to the position shown in FIGS. 1 and 2. In the sheet binding tool shown in Fig. 1, by pulling the tongue opening tool 7 located at the position shown in the figure in the direction of the arrow, the tongue 4 will bend in one step and the defective part 3 will open, allowing the sheet to be removed or bound. However, in the sheet binding device shown in FIG. 2, the tongue piece opening tool 7 is brought from the illustrated position to the position where the hole 7a hangs over the tongue piece 4, and the tongue piece 4 is held in one place by operating in the same manner as in FIG. It can be bent.

The sheet binding tool of the present invention is not limited to the above example, and even if the tongue piece 4 is a deformed extension of the binding arm 2', the binding arms 2, 2' may have an arc shape as shown in the figure. Rather, it may have a chevron-shaped or U-shaped shape, it may have one or more binding arms 2, 2', or it may not be attached to a file cover or the like. Further, the material of the base 1 and the binding arms 2, 2' is not particularly limited as long as it is rigid, and the material of the tongue piece 4 is not limited as long as it has elasticity as described above.

[Effects of the invention] As can be understood from the above description, the sheet binding tool of the invention has a simple structure, has a small number of parts, can be manufactured at low cost, and is suitable for binding firm sheets. When binding multiple sheets at the same time, or even sheets with no stiffness, this method has the advantage that the elastic tabs can be pushed open directly at the binding edge of the sheets without requiring any special operations. Even when stacking several loose sheets, you can easily open the elastic tabs by pushing them open with your fingers or using a flat plate like a 30cm ruler or a tab opening tool. Can be loaded. Furthermore, once the sheets have been stapled together, since the sheets are covered with elastic tongues in the direction in which the sheets come loose, there is an advantage that the stapled sheets will never come off no matter how they are handled. Furthermore, when replacing the sheets, the elastic tongues can be easily removed by simply using a simple tongue opening tool, thereby providing a sheet binding tool that is extremely easy to handle.
