Description

[Detailed description of the invention] Industrial application field: This invention is a method for binding leaves in a file containing transparent bag-shaped leaves, which is convenient for storing and organizing documents such as photographs and certificates so that they can be viewed from the outside. It concerns structural improvements.

Conventional Problems: Conventionally, as a means of organizing various documents, photographs, etc., a so-called clear file, which stores desired documents, etc. in a transparent bag-like leaf, has been used. Since this type of leaf is flexible, when it is bound into a single file, each leaf is bound in a fixed manner, and for this reason, the number of pages is limited to one, and it is not possible to increase the number of pages. It's summery. Therefore, when trying to store and organize the required amount of documents in one volume, even if there are many unnecessary parts, the missing parts must be stored in a new file, which is inconvenient.

Of course, it is already known that books and notebooks bound with ordinary paper have an addition/subtraction method, but this known method is not stable enough to be applied to storage leaves made of synthetic resin film. It was inappropriate.

Purpose of the invention: The object of the present invention is to solve the above-mentioned problems and provide a leaf binding structure that is configured so that even leaves made of flexible synthetic resin films can be added and removed without any problem.

Structure of the invention: In order to achieve the above object, the present invention provides a leaf clamping piece that is fixed to the binding back cover by a fastener in a file in which a plurality of file leaves made of transparent synthetic resin film are bound together. is the length corresponding to the binding side length of the leaf,
Made of thick plate material that can be folded into three to the appropriate width for clamping.
A suitable amount of gap is formed at the folded overlapping part of the inner folded piece and the front piece located on the front side, and the folded part between the front piece and the back side of the clamp is used to form the folded part of the leaf to be bound. A thin section wider than the maximum stacking height is formed, and a leaf is interposed between the inner folding piece and the clamping back piece, so that the rivet head fits between the inner folding piece and the front piece. In this way, the rivet stems are inserted into the holes provided in the pieces and each leaf, and long rivet insertion holes are made in the back piece of the clamp, and the rivets are fastened with fitting rivets on the outside of the back cover. be.

In addition to the rivet structure, the rivets are of a screw type structure, so that the leaf can be adjusted.

Embodiment: Next, an embodiment of the present invention will be described in detail with reference to the drawings. As shown in FIGS.
is formed, and the required number of leaves 2 in the form of transparent synthetic resin bags are attached to the inner side of the base of the book-bound back cover 1'' near the spine 1' of the cover 1 by the leaf clamping piece 10.
In this album, the leaf holding pieces 10 have a three-fold structure, and the required length L is equal to the length of the cover 1, as shown in FIG. The length should be the same as or slightly shorter than the vertical dimension L', and in the width direction, the width _l1 of the inner folding piece 11 is shorter than the width _l2 of the front piece 12, and the total width l of the clamping back piece 13. In addition to the dimensions of the front piece 12, ₃ has dimensions corresponding to the holding allowance for the leaf, and the bent portion 1 corresponding to the holding allowance is
The width l ₄ of 4 has a sufficient margin than the normal dimension (width wider than the maximum binding height dimension as a file), and the folded part 14, the front piece, and the inside folded piece are Each of the bent portions 15 is thinner than the thickness of each of the pieces 11, 12, and 13. The leaf holding piece 10 may be made of synthetic resin, or each piece may be made of thick paperboard and covered with strong decorative paper to the required dimensions, and then formed into one piece and bent. Both parts 14 and 15 may be made of the decorative paper. A fastener insertion hole 3 for binding a large number of bag-shaped leaves 2 made of transparent synthetic resin film for storing objects is a round hole 16 in the inner folding piece 11.
Elongated holes 17 of appropriate dimensions are formed at corresponding positions in the back of the clamp 13, and in order to be able to add and remove the leaf 2 during binding, male screw studs 5 and 5 are provided as shown in FIG. The female screw studs 6 are screwed together, and a large number of leaves 2 are bound by being pinched by the clamping pieces 10 against the base a of the back cover 1''.At this time, the heads 6' of the female screw studs 6 are folded inside the clamping pieces 10. The rivets are interposed between the piece 11 and the front piece 12 and fastened so that the rivet heads are not visible when the cover is opened.

According to the present invention constructed in this way, normally the standard number of transparent bag-like leaves 2 as shown in FIG.
The opened pieces are combined as described above with screws 5 and 6, and used by being fastened to the cover 1. In this state, the clamping pieces 10 are folded in three as described above, and the front piece 12 and the back side are attached. Since there is a thin folded part 14 with a required width and a sufficient margin between the folded part 13 and the folded part 13, the folded part 14 and the folded part between the front piece 12 and the inner folded part 11 are The bent part 15 exhibits a cushioning function, and the inner folding piece 11 and the back piece 13 can be fastened in a parallel state regardless of the amount of the leaf 2 to be bound, so that reliable binding can be achieved.

In addition, by using screw studs for binding, if you want to increase the number of leaves 2, you can unfasten them by pulling out the male screw studs 5 screwed in from the back cover 1'' side. If you open the back piece 13, add a new leaf 2, and staple it again, the folded part 14 will extend by the amount that the binding height increases due to the increase in the number of leaves, as shown in FIG. It is possible to clamp and fasten the pieces 13 without any hindrance due to lateral displacement.Of course, there is no problem because the rivet insertion portions are elongated holes 17.Even in this case, the back piece 13 and the inner folding piece 11 are parallel to each other. Since the leaf 2 is held and clamped, the operation of turning over the leaf 2 will not be hindered in any way.

Effects of the invention: As described above, according to the invention, when binding flexible bag-shaped leaves made of synthetic resin into a single file, a group of leaves can be assembled by using a clamping piece folded in three at the attachment point to the cover. When clamping and fixing the base of the leaf, the back piece that directly clamps the binding part of the leaf and the inner folding piece are parallel to each other so that the leaf can be correctly clamped, and the front piece folded in three makes it possible to secure the leaf with rivets on the front side. Since the head is not exposed, it has a good-looking finish, and by using screw tacks, it is possible to increase or decrease the number of leaves to be bound, and even with one file, the number of leaves can be added and bound according to the capacity. This also allows for the convenience of being organized.

In addition, when binding the leaves with a fixed amount of binding, the well-known mating rivet rivets 6a and 6b are used.
may also be used (see Figure 5).
