Description

[Detailed explanation of the invention] [Purpose of the invention] A structure for accurately and easily pulling out loose-leaf notebooks that can be stacked in parallel or stacks, and a spine that is flexible in opening and closing and has a high degree of durability despite the thin and lightweight spine. In addition, the loose-leaf paper is structured so that it does not bend significantly at the binding location and more sheets can be bound.

[Industrial application field]

The present invention relates to a back body structure of a file notebook that has a retractable take-out handle and is equipped with a binder for binding loose-leaf sheets.

[Conventional technology]

Conventionally, in order to pull out this type of file notebook, there was no handle at all, or even if there was a handle, it protruded greatly to the outside, or the position of the frame hole for holding the finger was fixed. However, there is no product that takes advantage of the characteristics of polypropylene, in which when the bending part is made thin, the bending part becomes more flexible, flexible, and strong and durable. In addition, the binder attachment point bulged out, and there was no way to avoid bending the loose leaf part too much.

[Problem that the invention attempts to solve]

Therefore, the present invention can be easily pulled out using the ring-shaped handle that is normally stored, and both the spine and the handle are in the form of a thin flat plate. On the contrary, it should have flexibility and durability, and should have a structure that does not bend significantly at the location where the binder is attached.

[Structure of the idea]

[Means for solving the problem] Therefore, in the present invention, a foldable drawer handle is attached to the spine, and the spine and the handle are molded from polypropylene. The connecting parts connecting the front and back covers on both sides of the cover are formed in the thin wall part, and both sides of the spine where the binder is attached inside the spine are formed higher inward. .

[Function] Normally, the ring-shaped handle body is stored in the recess on the outer surface of the back body so as not to get in the way, but when pulling out file notebooks that are parallel or stacked,
The file notebook can be easily pulled out from the shelf by pulling the finger on the ring-shaped handle and pulling it outward, and the folded parts formed on both sides of the handle and spine are thin so that it can be easily bent. It is easy to open and close, and since the molding material is polypropylene, it has the flexibility and high strength and durability that is characteristic of polypropylene, so when the file notebook is opened and opened,
The loose-leaf part facing from the binder to the cover side is supported by the high side of the spine and does not cause large bending, achieving the desired effect and being stored in this. Since the paper that is used can also be filed without being rubbed, it is possible to file a larger amount of paper than before.

〔Example〕

Next, the embodiment shown in the drawings will be described.

Figure 3 shows a perspective view of the entire file notebook.
Both side parts 1a and 1b of the elongated back body A, which has a plurality of engaging protrusions 8 for attaching the binder C formed on the inner side, are formed high so as to curve inwardly, and the outer sides of the both side parts 1a and 1b are formed high. Both extended surface parts a, a, which can connect and lock the back cover 3 and the front cover 2, are integrally formed so as to be connected via bendable thin hinge parts 4a, 4b, and a heading plate 9 is provided on the back surface of the spine body A.
It is made of polypropylene material so that it can be attached.

A recess 5 is formed in the lower back surface of the back body A, and the lower part is curved in a semicircular shape and serves as a stepped surface of a constant depth.Both holes 6 penetrating inside and outside are formed on both upper sides of the recess 5. ，
6 and configure it.

Reference numeral B designates a ring-shaped handle body, which is formed by boring a round hole or a hole 9 into which a finger can be inserted into a flat plate, and a thin V-shaped cut part 10 is formed at the upper end of the handle body B, and a hook-shaped part is formed at the upper end of the handle body B. Both protrusions 7, 7 are formed so as to protrude so as to be bendable, and the protrusions 7, 7 are respectively fitted into the two holes 6, 6 in the direction of arrow A as shown in FIG.
As shown in Fig. 11, the end hooks of the protrusions 7, 7 are installed so that they engage inside the holes 6, 6 and do not come off, but instead of using the above structure, the engaging parts are heated. It can also be attached by welding.

In addition, in the figure, 11 is a loose leaf.

[Effects of the invention] As described above, the spine and handle of the invention are made of polypropylene material, so it is easy to pull out the desired notes from individual, parallel, or stacked loose-leaf notebooks. The handle body formed or housed integrally with the back cover of the notebook is pulled out by placing one's fingers on the handle body, and as mentioned above, the handle body B of the present invention is bent from the thin wall portion 10 and inserted into the recess 5. Since it is fitted, the file notebook can be removed from the shelf very easily by inserting the tip of a finger into the hole 9 of the handle B in the recess 5, hanging it, bending it outward, and then pulling it. On the other hand, the handle body, which can be pulled out when stored, can be smoothly folded into the recess 5 and stored in a state where it does not protrude outside at all. The entire back cover and handle body are molded from polypropylene material, and especially the thin hinge parts 4a and 4b and the bent part of the handle body B are
It exhibits extremely high bending and restoring properties against forces applied to the thin layered portion, which are characteristics of polypropylene, and durability that does not change in the slightest even after long-term use, and both sides of the back body A Since the portions 1a and 1b are formed high inwardly, the portion of the loose leaf 11 extending from the binder C toward the back cover 3 is supported by the inner surface of the side portion 1a and can be unfolded without being bent significantly. Therefore, this type of loose-leaf notebook is ideal for storing a large amount of note paper, has a compact structure with good overall appearance, is highly durable, and is simple and suitable for mass production. It can be said that it has a similar structure.
