Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a bookbinding structure in which required sheets of paper are bound between the front cover and the back cover using twin wire rings or spiral rings.

[Prior Art] A front cover having a plurality of file holes at the binding base,
A bookbinding structure in which sheets of paper and a back cover are bound using twin wire rings or spiral rings is applied to various things such as telephone directories and memo pads. In other words, this type of structure does not have the problem of the open page closing automatically due to the cover or the paper coming back, and it is also easy to manufacture, so it is widely used for various types of ledgers. There is.

[Problems that the invention aims to solve] However, with this structure, the cover and paper can be freely rotated along the ring, and there is no hook or the like at all. . Therefore, there is an inconvenience that it cannot be used by hanging it on a wall or the like.

The present invention aims to solve these problems.

[Means for Solving the Problems] In order to achieve the above objectives, the present invention employs the following configuration.

That is, the bookbinding structure according to the present invention is one in which a front cover having a plurality of file holes at the binding base, paper, and a back cover are bound by twin wire rings or spiral rings, and the back cover is bound by a twin wire ring or a spiral ring. A folded piece having a file hole that matches the file hole when overlapped with the outer surface of the back cover is hinged to the edge of the binding base of the back cover, and a hook part is provided on this folded piece. Features.

[Function] With such a structure, if the folded piece with the hook is superimposed on the outer surface of the back cover, the folded piece forms a part of the back cover. and can be used in exactly the same manner as conventional ones.

On the other hand, if the folded piece is rotated in a direction away from the outer surface of the back cover to stand up, the folded piece can be used as a hook. That is,
When this folded piece is rotated through the hinged part, the folded piece stands up while being guided by the twin wire ring or the spiral ring, and the folded piece and the back cover become substantially flush with each other. Become. the result,
The rotating end of this bent piece is located above the ring, and the hooking portion of the bent piece can be hooked to a suitable hook. In this state, the twin wire ring or the spiral ring threads through the file hole of the bent piece and the file hole of the back cover.

[Embodiment] Hereinafter, an embodiment in which the present invention is applied to a telephone directory will be described with reference to the drawings.

As shown in FIGS. 1 to 3, this telephone directory 1 is made up of a front cover 2, a plurality of sheets of paper 3, and a back cover 4 bound together using twin wiring 5.

The front cover 2 is made of a thin synthetic resin board, and has a plurality of file holes 22 at its binding base 21.

The paper 3 is formed by printing a predetermined form, and has a plurality of file holes (not shown) at its binding edge 31.

The back cover 4 is made of a slightly thick synthetic resin board, and has a plurality of file holes 4 at its binding base 41.
It has 2. A bent piece 6 is provided at the end edge of the binding base 41 via a hinge part 43.

The folded piece 6 is made of synthetic resin and is molded integrally with the back cover 4, and the hinge portion 43 is formed by forming a thin boundary portion between the folded piece 6 and the back cover 4. It is something. The vertical dimension of the folded piece 6 is set to be much shorter than the dimension of the back cover 4, and a file hole 62 is bored at its binding base 61. This file hole 62 is arranged so that when the folded piece 6 is superimposed on the outer surface 4a of the back cover 4, it can almost completely coincide with the file hole 42 of the back cover 4. A through hole 63 serving as a hook is bored in the center of the pivoting end of the bent piece 6.

The twin wire ring 5 is a normal wire ring formed by forming a metal wire into a pulse wave shape and deforming each waveform portion into a ring shape.

With such a configuration, when the folded piece 5 is superimposed on the outer surface 4a of the back cover 4, the folded piece 6 becomes a part of the back cover 4, It can be used in exactly the same manner as conventional ones. That is, in this state, the bent piece 6
Since the back cover 4 and the back cover 4 can be freely moved along the twin wiring 5, the folded piece 6 does not get in the way when the covers 2 and 4 are opened and closed.

On the other hand, as shown in FIGS. 4 to 6, if the folded piece 6 is rotated in the direction away from the outer surface 4a of the back cover 4 and raised, the folded piece 6 can be used as a hook. It becomes possible. That is, when this folded piece 6 is rotated via the hinge portion 43, this folded piece 6 stands up while being guided by the twin wire ring 5, and the folded piece 6 and the back cover 4 are substantially in plane. become one. As a result, the rotating end side of the bent piece 6 is located above the twin wire ring 5, and the through hole 63 of the bent piece 6 can be hooked to an appropriate hook. Become. In this state, the twin wire ring 5 threads through the file hole 62 of the bent piece 6 and the file hole 42 of the back cover 4.
Therefore, the distance between the file hole 62 and the file hole 42 in this state does not necessarily need to be set equal to the diameter of the twin wire ring 5, and may be slightly smaller than that diameter.

Note that the shape of the bent piece is not limited to that of the embodiment described above, and various modifications can be made without departing from the spirit of the present invention.

Further, in the above embodiment, a case was explained in which a twin wire ring was used, but the present invention can be similarly applied to a case using a spiral ring in which a metal wire is spirally wound.

Note that the applicable object is not limited to a telephone directory, but may be a memo pad or the like.

[Effects of the invention] Since the present invention has the above-described configuration, it can be used as needed without sacrificing any of the advantages of twin wire ring or spiral ring binding.
It is possible to provide a bookbinding structure that can be hung on a wall or the like by a simple operation.
