Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a binding string for binding documents for easily assembling paper products such as printed matter and sticky notes.

[0002]

2. Description of the Related Art Conventionally, for binding documents, only temporary documents are bound with a stapler, a clip or the like, and those which are stored for a relatively long time are stored in a paper or plastic file serving as a cover. Often housed. There are various types of the latter type. Among them, the combination of paper cover and binding string is the oldest and still widely used form. The feature of this combination is that the amount of documents to be bound can be given a range by re-binding the binding string.

[0003]

Since the binding string has a fixed length and is not stretchable, it is difficult to tie the binding object by giving a proper tension to the binding object, and the binding object naturally loosens over time. Also, it is sometimes difficult to make a knot because the edges are processed to be harder. Furthermore, there is also a problem that a binding string used once has a habit and is difficult to reuse. SUMMARY OF THE INVENTION An object of the present invention is to provide a binding strap for binding a document, which gives an appropriate tension regardless of the thickness of the bound document, has no knot, and is easily attached and detached.

[0004]

SUMMARY OF THE INVENTION According to the present invention, a binding member having a longer diameter than a document binding hole is formed at both ends of a binding string main body of a required length using an elastic material, and a locking function is provided to the binding string. Is a binding string for binding a document.

[0005]

According to the present invention, a part or the whole of the binding string is formed of an elastic body, and a falling-off preventing material which also serves as a guide portion when passing through the hole at both ends is formed. Therefore, while binding the documents having different lengths, the binding string can apply an appropriate tension to the binding portion by the elasticity of the elastic body while the binding straps have a fixed length. Also, the document does not require a knot because it is locked by the captive material.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION There are two types of binding a document with a binding string, using only the binding string and using an auxiliary tool in addition to the binding string. The application method is effective when the binding thickness is small in the former case and is effective when the binding thickness is large in the latter case. That is, when the document is thick and heavy, the binding string passed through the binding hole is extended, a strong force is applied to the locking material at both ends, and there is a concern that the locking material may be bent or fall out of the binding hole, and the latter is used. .

In order to form the fall-prevention material, it is economically preferable to form a synthetic resin by injecting it into the binding cord main body, but it is also possible to use a metal coating.

[0008]

FIG. 1A shows a binding string 1 having a locking function.
It is a perspective view before use. The falling-off prevention members 4 are attached to both ends 3 of the binding string main body 1. As shown in FIG. 1 (B), the fall prevention member 4 is a rod made of a synthetic resin and having a length of about 1 to 2 cm, and is fixed to the binding cord main body by injection molding in a vertical direction. The binding string main body 2 uses an elastic material such as a rubber string or a composite string of rubber and a fiber material.

FIG. 2A shows a document 6 having two binding holes 7.
It is an example of use of the binding string applied to. The document is fixed by putting the fall prevention member 4 through the binding hole 7 of the document in parallel with the binding string main body 2 and then returning to the T-shape again. FIG. 2B is an example of use of a binding string applied to a document having a large number of binding holes such as a loose leaf. FIG. 2C is an example of use when there is only a longer binding string for the bound document. According to the usage of this drawing, it is possible to prevent the bound document from bending due to the elasticity of the binding string depending on the position of the binding hole.

FIG. 3 (A, B, C) shows another embodiment of a material for preventing the binding string from falling off. 3A of FIG. 3A.
Has the same appearance as that of FIG. 1, but is covered with a hard material (metal plate) having a long hole 5 and integrated. The drop-prevention member 4B in FIG. 3B is formed by forming a bilaterally symmetric T-shape with plastic at the end of the binding string and integrating them. The drop prevention member 4C in FIG. 3C is formed by integrally forming a T-shape, which is not symmetrical with the left and right, with plastic so that the end of the binding string can be easily passed through. T
It is necessary to make the material for preventing the character from falling off so that the overlapped portion with the binding string is not too large or too small than the binding hole at the time of passing through.

FIGS. 4A and 4B are perspective views of a binding string 11 of a type using an auxiliary tool and having a locking function. FIG.
In (A), the left side is a state before the fall prevention member 14 (the binding string side) and the auxiliary tool 15 are combined, and the right side is a state where both are combined.

Also in this embodiment, the end of the binding string main body 12 is T
It is the same as the fall-prevention members 4, 4A, 4B, and 4C of the previous embodiment in that they are formed into a letter to form the fall-prevention material 14,
Another difference is that an auxiliary tool 15 is used. Aid 1
5 is made of a disc, and has on its surface a locking groove 16 having the same shape as the falling-off preventing material and a cut 17 in a part of the T-shape.
At the time of use, the binding strap drop-off prevention member 14 extended through the binding hole is inserted into the locking groove 16. In addition, the binding string 1 with various T-shaped fall-off preventing materials 4A, 4B, 4C shown in the above-described embodiment.
Can also be used.

FIG. 5 shows the structure of the falling-off prevention member shown in FIG.
FIG. 4 is a perspective view of a state in which two documents with a binding hole are bound. It can also be used for documents with multiple binding holes, such as loose leaves.

As a modified example, as shown in FIG. 4B, a spherical fall prevention member 18 may be used and fixed with an auxiliary tool 15A having a spherical fitting portion.

In these methods, since the auxiliary tools 15 and 15A receive the force acting on the binding string main body, there is an effect of preventing the binding string 12 from dropping out of the binding hole.

FIGS. 6A and 6B show another embodiment of the binding cord and the assisting device. FIG. 6 (A) shows the auxiliary tool 18 provided with locking grooves 19 for fixing both ends of the binding string. FIG. 6B shows a structure in which at least three locking grooves 21 are provided on the auxiliary tool 20 like a washing plate, and the length can be adjusted by changing the locking groove at the binding string end.

[0017]

According to the elastic binding strap for binding a document of the present invention, the following effects can be obtained.・ It is not necessary to bind the binding string.・ The habit is not attached to the string and can be used repeatedly. -Since the binding string body expands and contracts, a single string can be used to bind documents having different thicknesses.・ The full length of the binding string can be used. -The binding structure stabilizes the binding condition. -Strength can be increased by using an auxiliary tool. -If a long string is applied to a material that is strong and resistant to bending, such as paperboard, it can be used for hanging on a wall.
