Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a bookbinding file, and more particularly, to an improvement of a bookbinding file that can securely bind materials such as paper and documents so as not to drop out.

[0002]

[Prior Art]

 As a conventional bookbinding file of this type, there is known a file provided with a clamp portion made of a shape memory member on the spine cover portion which is closed at room temperature and opened when a predetermined temperature is exceeded. Further, as a bookbinding machine for binding this file, it has a heating means and a file support part for supporting the bookbinding file on the heating surface side of the heating means, and the clamp part provided in the bookbinding file is used as the heating means. There is known a structure in which the bookbinding file is heated to open and the document is introduced, and then the bookbinding file is kept at room temperature to close the clamp portion so that the document is bound in the file (Japanese Patent Laid-Open No. Hei 3). -83692 gazette).

[0003]

[Problems to be solved by the device]

 However, in the conventional bookbinding file of this type, since the force for binding the material depends only on the clamping pressure of the clamp part, the binding force in the direction of the surface of the material is weak, especially when the inside of the spine cover is full. When a material having a thickness dimension is bound, a part or all of the material may drop off, and if a part of the material falls off, the rest of the material may lose its binding force and fall off entirely.

In addition, since the width dimension of the clamp part in the state of being heated and opened by the bookbinding machine is set so as to correspond to the materials having various thickness dimensions, when binding relatively thin materials Has a gap between the clamp and the material. If there is a gap between the clamp and the document, it will take a certain amount of time for the clamp to return to room temperature.Therefore, when the file is removed from the bookbinding machine or during the subsequent movement, the document is aligned. The row condition is likely to be disturbed. In addition, if the files are left inside the bookbinding machine until the clamp part securely holds the material, there is a problem that the efficiency of bookbinding work is poor.

On the other hand, although it is possible to carefully take out the file from the bookbinding machine so that the aligned state of the materials is not disturbed, there is a problem that the work is complicated and requires skill. Further, the efficiency of bookbinding work can be improved by adding a cooling device for cooling the heated file to the bookbinding machine, but the problem arises that the bookbinding machine becomes large and the cost increases.

The present invention has been made in view of the above circumstances, and it is possible to reduce the size of the bookbinding machine and easily maintain the aligned state of the materials, while the material is securely bound so that the materials do not drop out. It is an object of the present invention to provide a bookbinding file capable of improving the efficiency of bookbinding work.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the bookbinding file of the present invention is provided inside the spine cover part, and when the temperature exceeds a predetermined temperature, the binding part of the material can be introduced, while at room temperature, the binding part of the above-mentioned material is introduced. A shape memory member that is closed so as to be sandwiched in the thickness direction, and an adhesive or a pressure-sensitive adhesive that is applied to the inside of the shape memory member and that adheres or sticks the binding portion of the material. is there.

In this invention, as the shape memory member, for example, a shape memory alloy or a shape memory resin can be used.

Further, the shape memory member is provided inside the spine cover portion and opens when the temperature exceeds a predetermined temperature so that the binding portion of the material can be introduced. At room temperature, the binding portion of the material is oriented in the thickness direction. As long as it is sandwiched between the two, the shape memory member may be composed of one short shape memory member piece or a plurality of shape memory member pieces arranged in the longitudinal direction of the spine, but it is preferably a length through shape. It is better to have

[0010]

[Action]

 To bind the material to the bookbinding file of the present invention configured as described above, first open the shape memory member by heating the file with a bookbinding machine and then apply the adhesive applied to the inside of the shape memory member. The binding part of the material is adhered or adhered to the adhesive or adhesive. Then, if the file is taken out of the bookbinding machine and left to stand, the shape memory member returns to room temperature and is closed so as to sandwich the binding portion of the material in the thickness direction.

Here, in the case where the shape memory member is coated with an adhesive, the file on which the material is bound is heated again by the bookbinding machine to open the shape memory member. Materials can be peeled off and files can be reused.

Further, if the shape memory member is provided in a longitudinal shape, it is possible to stably hold the material.

【Example】

 An embodiment of the present invention will be described below in detail with reference to the drawings.

First Embodiment FIG. 1 is a perspective view of the bookbinding file of the present invention developed in a room temperature state for the bookbinding file of the first embodiment, and FIG. 2A shows heating of the file of FIG. FIG. 2 (b) shows a side view after heating the file of FIG. 2 (a).

The bookbinding file 1 of the present invention is provided with a file base 5 in which a front cover 2 and a back cover 3 can be folded via a spine cover 4, and an inside of the spine cover 4 of the file base 5. The shape memory member 6 and the adhesive or pressure-sensitive adhesive (hereinafter referred to as adhesive) 7 applied to the inside of the shape memory member 6.

The file base 5 is formed of a single heat conductive member such as a metal sheet, a conductive plastic sheet, or a metal vapor deposition film, or a composite member thereof.

The shape memory member 6 is composed of a longitudinally extending base portion 6a fixed to the inside of the file base portion 5 and a pair of holding pieces 6b and 6b which are integrally erected from both side portions of the base portion 6a. When the temperature exceeds a predetermined temperature (shape change temperature higher than room temperature), the binding part a of document A can be introduced by opening it in a substantially U-shaped cross section as shown in FIG. 2a is closed so as to be sandwiched in the thickness direction as shown in FIG. 2 (b). The shape memory member 6 is formed of, for example, a shape memory alloy or a shape memory resin, and polynorbornene, polyisoprene, a styrene-butadiene copolymer, polyethylene or the like is used as the shape memory resin.

To bind the material A using the bookbinding file 1 of the present invention configured as described above, a desk-top binding machine 10 as shown in FIG. 3 can be used.

That is, first, the file 1 is held upright on the heating surface of the heating unit 11 of the bookbinding machine 10 by the file supporting units 12 and 12. When the heating unit 11 is heated in this state, the heat of the heating unit 11 is transferred to the shape memory member 6 via the file 1, the holding pieces 6b, 6b of the shape memory member 6 are opened, and then the shape memory member 6 is opened. The binding portion a of the material A is introduced in an aligned state to the adhesive agent 7 applied to the inside of the sheet, and is adhered or adhered. Next, when the file 1 is taken out from the bookbinding machine 10 and left to stand, the shape memory member 6 returns to room temperature and the free ends of the holding pieces 6b, 6b close so as to hold the binding portion a of the material A in the thickness direction. Jijiru

Therefore, since the binding portion a of the material A is bound to the file base 5 by the adhesive force or the adhesive force of the adhesive agent 7 and the holding force of the shape memory member 6, the thickness dimension of the material A is Even if the inside of the spine cover 4 is full, a part or all of the material A can be reliably bound without falling off. Moreover, even when the file 1 is taken out of the bookbinding machine 10 until the sandwiching pieces 6b, 6b of the shape memory member 6 return so as to close at room temperature, the binding part a of the material A is adhered by the adhesive 7 or the like. Therefore, even if the file 1 is moved, the aligned state of the material A is maintained, and the efficiency of bookbinding can be improved. Further, since the bookbinding machine 10 is not provided with a special cooling device, the bookbinding machine 10 can be downsized and the cost can be reduced. Moreover, in this case, since the shape memory member 6 is provided in a longitudinally extending shape, the material A is stably sandwiched.

It is transmitted to the means and the control unit of the heating unit 11.

When a pressure sensitive adhesive is used as the adhesive 7 or the like, if the shape memory member 6 is opened by heating the file 1 bound with the material A again with the bookbinding machine 10, the adhesive is The material A can be peeled off from the file, and the file 1 can be reused to bind the material A or another material.

As the above-mentioned adhesive 7 or the like, a usual adhesive or pressure-sensitive adhesive may be used, or a thermoplastic adhesive or the like may be used. In this case, the adhesive agent 7 melts under high temperature and penetrates into the binding portion a of the material A, so that the adhesiveness can be improved.

In the following, with respect to other embodiments, the same parts as those of the first embodiment will be described with the same reference numerals.

Second Embodiment FIGS. 4 (a) and 4 (b) show a side view of the second embodiment of the bookbinding file of the present invention during heating and a side view after heating.
