JP2002144781A - Binding utensil and file using the same - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a binding utensil which is small, light-weight, has a large capacity, and is excellent in spreading property, replacing property for leaf papers, and strength, and a file or a binder or the like for which the binding utensil is used, in a punched hole type file, a binder or the like having multiple holes such 2 holes, 6 holes and others. SOLUTION: A binding utensil base section (2) having a belt section (4) of which the material is, e.g. a synthetic resin or the like having flexibility is fixed to the right and the left on the internal side of a back (1). On the lower side and the upper side of the base section (2), a gap in which the belt section (4) of the confronted binding utensil is housed is provided. Leaf papers are fixed by passing the belt from both of the right and left sides of one punched hole.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a binding device, a file, a binder, and the like for binding together punched sheets.

[0002]

2. Description of the Related Art Conventional files of this kind include a file having a ring which can be opened and closed, a file having a combination of a belt and a stopper, and a file having a combination of a belt and a receiving hole.

[0003]

The one having a ring that can be opened and closed is bulky, the one that combines a belt and a retaining bracket has low spreadability, and it is difficult to replace a sheet in the middle. The combination is
There is a problem that it is difficult to use a two-hole file.

The present invention has been devised in order to solve the above-mentioned problems, and is a small-sized binding device and a file having a good sheet-sheet replacement property, a good sheet-spreading property, and a low cost. And a binder.

[0005]

According to the present invention, in order to solve the above-mentioned problems, a binding device having a flexible belt made of, for example, synthetic resin or the like is fixed to opposing positions on the left and right sides inside the spine.

A gap is provided below the pedestal of the binding device for accommodating the belt portion of the binding device.

[0007] Further, a gap for accommodating the belt portion of the opposing binding tool is provided above the pedestal of the binding tool.

[0008]

Embodiments of the present invention will be described below with reference to the drawings.

[0009]

Embodiment 1 FIGS. 1 and 2 show specific examples. Spine (1)
A binding pedestal portion (2) having a flexible belt portion (4) made of, for example, synthetic resin is fixed to the left and right sides. The belt portion (4) is integrated with the pedestal portion (2) or fixed to the pedestal portion (2) by a method having rigidity in the vertical direction of the spine (1). Also, the joint (5) between the pedestal (2) and the inside of the spine (1) is located at a position avoiding directly below the belt, and has a rigidity in the vertical direction of the spine (1). It is fixed to.

FIG. 3 shows a procedure for inserting a paper sheet.
When sandwiching the paper sheet (6), any one of the left and right belt portions (4) is inserted into the paper sheet punch hole (7) from below the other belt. The belt that has been pierced serves as a guide, the belt is smoothly inserted, and the belt slides into a gap provided immediately below the binding device (2). Next, while lifting the sheet (6), the other belt part (4) is inserted into the sheet punch hole (7) from above the other belt. Also in this case, the other belt serves as a guide, and the belt is smoothly inserted. Since the belt comes out to the upper part of the binding device, it is inserted into a gap provided between the belt and the upper component of the binding device (3).

[0011]

Second Embodiment FIG. 4 shows a second embodiment. In order to adapt to changes in the position and number of holes and to use it on a general-purpose backing paper, a binding tool (2), (3), and (4) for one hole is integrated and attached to the backing paper. did. By separating the sheet at the center, it can be used by attaching it to a position corresponding to the number of sheets.

[0012]

The file and the binder using the binding device according to the present invention can be used in the generally used two-hole type files.

[0013] The file is light, thin and compact, and the space required for the binding device is small, so that the file can be light, thin and compact.

A large number of paper sheets can be bound.

Sheet spreadability is excellent, and paper sheets can be easily replaced on any page.

Since the belt supports the sheet from the left and right, and the belt is doubled, the strength is high.

[0017]
