Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a binding device, and more particularly to a binding device for binding documents, for example, a rail type binding device for documents.

[0002]

[Prior art]

 Conventionally, as a binding tool for binding a small amount of documents in the binding margin without opening a through hole, a flat rectangular shape is formed so that two adjacent sides are welded and the other two adjacent pieces are opened without being welded. A holder type file such as a polypropylene holder is generally used. As other files, as shown in FIG. 9, a document is sandwiched between cover sheets 1 and the binding margin 2 of the cover sheet 1 is used as a document. There is also a binding tool formed so that it can be inserted through the rail-type binding tool 3 and that a document bound between the covers can be viewed with a spread part that is not pinched by the rail-type binding tool 3.

[0003]

[Problems to be solved by the device]

 However, among conventional binders, the holder-type file has the convenience that filing can be performed simply by inserting the document into the file through the opening, but it is difficult to browse the filing document, and for example It is inconvenient because some documents are separated during use. In the case of a file in which a rail-type binding device is used to sandwich a document, the rail-type binding device 3 is relatively thick, and the cover 1 is pulled in a direction orthogonal to the length direction of the rail-type binding device 3. When the cover sheet 1 is folded in two, the two folded portions are formed by two folding lines 5 and 6 having a width of, for example, 3 mm. The spine cover portion 7 does not function to prevent the rail-type binding device from coming off and the cover sheet 1 does not come off, but it is sandwiched between the cover sheets 1 that are relatively less engaged with the rail-type binding device 3. There is a risk that the documents that have been cut out may come off if the holding force of the rail-type binding device 3 is insufficient. In addition, the file using this rail-type binding tool is not applied to any other application, and can only be filed as it is.

Therefore, a main object of the present invention is to provide a binding device in which a cover sheet sandwiched by a rail-type binding device and a document such as a document sandwiched between the cover sheets are hard to come off.

[0014]

[Effect of device]

 According to the first to seventh aspects of the present invention, the problems of the conventional rail type binding device can be solved. That is, a conventional rail-type binding device that slides a binding object such as a document by sliding it on the end face of the binding margin portion of the cover has a thick portion where the cover of the rail-type binding device is sandwiched and binding is performed. The folded cover has a spine that has two folds at the two folds, so if the spine is pulled in the direction perpendicular to the rail-type binding device, The cover prevents the cover from slipping out of the rail binding, but the rail binding is also thicker to accommodate the spine of the cover.

However, according to the binding device of claims 1 to 5 of the present invention, the opening of the rail-type binding device makes it difficult for the opening of the rail-type binding device to come off in the width direction of the rail-type binding device when the cover is pinched. A stopper is formed, and the cover has a protrusion that is located inside the opening of the rail-type binding device and is engaged with the rail-type binding device when it is pinched by the rail-type binding device. Since it is formed continuously in the lengthwise or widthwise direction, the slip-off prevention of the rail-type binding and the projection of the cover are engaged, so that the binding such as documents sandwiched between the cover and the cover is Is hard to come off.

According to the third aspect of the invention, in particular, the front cover is a continuous double-fold of the front cover and the back cover, and is located in the vicinity of the double-folded part and inside the double-folded part. Since the protrusions are formed, the spine between the front cover and the back cover of the front cover is unnecessary, and since the part for accommodating that part of the rail binding is unnecessary, the rail binding can be made thin and small Best for binding papers. If there is less play between the protrusions on the cover and the space for the rail-type binding device that accommodates the protrusions, the cover will not recoil even when pulled in the width direction of the rail-type binding device. Is stably bound.

According to the invention of claim 7, a wire is fitted in a through hole formed in the longitudinal direction of the rail-type binding tool to hold both ends of the wire protruding from both ends of the rail-type binding tool. Since it can be bound to a file with locking members formed on the upper and lower ends of the spine such as a magazine file, even if the cover is relatively weak, for example If it is strong, it can be stored upright, for example.

The above-mentioned objects, other objects, features and advantages of the present invention will be more apparent from the following detailed description of the embodiments with reference to the drawings.

A binding tool 10 according to an embodiment of the present invention includes a long rail-type binding tool 12 and a cover sheet 14 held by being sandwiched by the rail-type binding tool 12.

The rail-type binding device 12 is made of hard vinyl chloride having relatively elasticity, is a long rail type having a rectangular shape in a plan view and a substantially U-shaped cross section, and has an opening 16 at one longitudinal end thereof. The connecting portion 18 is formed on the longitudinal edge opposite to the longitudinal edge on which the opening 16 is formed. The opening 16 of the rail-type binding device 12 is provided with a retainer 20 for preventing the rail-type binding device 12 from coming off in the width direction when the cover 14 is pinched.

The cover sheet 14 is located inside the opening 16 of the rail-type binding tool 12 when being sandwiched by the rail-type binding tool 12, and is locked with the retainer 20 of the rail-type binding tool 12. The protrusions 22 are formed continuously in the longitudinal direction. The front cover 14 is a polypropylene sheet that has been subjected to an antistatic treatment and is folded in two by Thomson processing, and the front cover 14a and the back cover 14b are left and right via the two folded portions 24 by the Thomson processing ruled lines. The front cover 14a and the back cover 14b are formed symmetrically and are continuous with each other with the folded portion 24 interposed therebetween. Then, in the vicinity of the two-folded portion 24, a protrusion 22 is formed inside the two-folded portion 24, and the protrusion 22 is a flat rectangular protrusion extending in the longitudinal direction of the cover sheet 14. No. 24 and 24 are linearly formed at regular intervals and are formed intermittently continuously at appropriate intervals.

The projections 22 are dimple-processed by pressing a hot blade heated from the back surface to the front surface of the polypropylene sheet forming the cover 14, and are rectangular elongated in the longitudinal direction of the cover 14, and the cover 14 can be drawn in the width direction. For example, the long end 22a of the protrusion 22 is engaged with the retainer 20 of the rail-type binding device 12, and the cover 14 is formed so as not to be easily pulled out in the width direction of the rail-type binding device 12. In this embodiment, when the front cover sheet 14a and the back cover sheet 14b are opened to the left and right, the projections 22 are linearly formed with a distance of 10 mm from the two folded portions 24 by about 10 mm from each other, and the projections 22 are formed by the dimple processing. A total of 50 locations are formed at 25 locations on 14a and 25 locations on the back cover. The protrusion 22 has a width of about 0.7 mm and a height of about 0.5 mm. However, the shape and the number of the protrusions 22 are not limited to this embodiment, and another structure may be selected as long as the cover 14 has a shape that makes it more difficult to pull out than the rail-type binding device 12.
