JPS6030065Y2 - Bookmark - Google Patents

Description

[Detailed explanation of the idea] This idea is about bookmarks.

Traditionally, there are various types of bookmarks, but since they need to be thinly formed, it is very difficult to make bookmarks serve other functions. The only options available were things like stickers or magnifying glasses with Fresnel lenses.

However, among these, the idea of combining a ballpoint pen core and a bookmark to double as a writing instrument can be said to be the most innovative.

However, it is just using a two-dimensional object in a two-dimensional manner.

Bookmarks are often made of paper that can be bent, and this project changes the idea of using conventional bookmarks on a flat surface to the idea of assembling and using them three-dimensionally. When the book is in this state, the bookmark can also function as a page holder to prevent the book from closing even if the left and right pages are not held down by hand.

The detailed description of this proposal using drawings is as follows.

Although it does not necessarily have to be vertically long, it is usually a vertically long bookmark body, and by folding at least 3 places in parallel, you can make 4
The block is divided into two block faces, and a cylindrical triangular prism can be formed as shown in FIG.

Assuming that each block face is the first, second, third, and fourth block face in order, the first block face 1 may have the same length as the second block face 2, and the third block face 3 may have an appropriately selected length. The fourth block surface 4 is made slightly longer than the first block surface 1 by about 1 cm for use in pocket-sized books.

Each block surface itself is made of a material having a strength higher than that of the plate-like cardboard of the minimum official postcard, and each fold 5 is made of a material that is easy to bend and sufficiently durable to be repeatedly bent.

The material having the above-mentioned function is preferably cardboard, and furthermore, a synthetic resin material such as polypropylene that can be bent at an acute angle is also suitable.

It is also possible to use a combination of pasting a board the size of each block onto thin paper or vinyl sheet material.

Some embodiments of this invention are shown below.

FIG. 1 shows a first embodiment of the present invention, which is made of a cardboard bookmark with folds 5.

FIG. 2 shows a second embodiment of the present invention in which groove lines 6 are formed on a thin plate of polypropylene material or the like to form crease lines.

FIG. 3 shows a third embodiment of the present invention, in which the fold guide line 7 is indicated by a color difference, a line, etc. in a pictorial pattern attached to the surface of the bookmark body.

FIG. 4 shows a fourth embodiment of the present invention, in which cutouts 8 are formed on both side edges of the bookmark body to indicate the guideline position of the fold.

FIG. 5 shows a fifth embodiment of the present invention in which another auxiliary block surface 3' is provided at the tip of the first block surface 1 with approximately the same length as the third block surface 3.

FIG. 6 shows a bookmark made up of three block faces that was devised before reaching the bookmark made up of four block faces according to the present invention.

Fig. 7 shows a body of the sixth embodiment of the present invention, which is formed by printing an overall view of the third embodiment of the present invention on one end of a postcard 9 in this figure, such as a cardboard body used as the bookmark material of the present invention. It is.

In this figure, the perforation line is machined with 10 perforations.

Figure 8 shows a seventh embodiment of the present invention, in which a punch hole 11 is provided at the end of the body of the seventh embodiment of the present invention, and the product is connected to other products with thread, etc., to make it cheaper, and the price is displayed, which also serves as a product price tag. It is.

FIG. 9 shows an eighth embodiment of the present invention, in which a plate 13 having the size of each block surface is attached to a flexible thin paper 12 or the like.

As mentioned above, it is easy to imagine many different embodiments of this invention by carefully selecting materials and combining it with other products.

This proposal is used as follows.

FIG. 10 is an assembly diagram of the present invention.

Normally, the bookmark is held in a flat position in the book as a bookmark, but when used as a page holder to keep the book spread open, which is the purpose of the present invention, it is assembled as shown in Figure 10.

Be sure to bend the fourth block surface 4 so that it is on the outside of the first block surface 1.

FIG. 11 is an assembled view of the fifth embodiment of the present invention, in which the plate-like strength of the third block surface 3 is supplemented by the auxiliary block surface 3', creating a stronger triangular cylinder structure.

Next, as shown in FIG. 13, the protrusion a of the fourth block surface 4 is
Insert it into the boundary groove 14 which is shaped like a book spread.

The second and fourth block surfaces 2 and 4 hold down the left and right pages of the book from closing, and the third block surface 3 supports the pressure from the left and right sides.

The advantages of this proposal will be described below by comparing it with the bookmark in Figure 6 that was devised in the lead up to the proposal.

The bookmark shown in FIG. 6 is assembled as shown in FIG. 12, and used by inserting both ends of the bookmark and the light on the open side into the book's boundary groove 14.

Both left and right pages are supported by making use of the structural strength of the triangular cylinder, and the thin bookmark body itself is inserted into the boundary groove 14 and fixed.

However, the major difference is that in this case, the triangular tube-shaped boundary groove 14 is used only for an auxiliary role, whereas in the bookmark shown in FIG. 6, it is used as an essential part.

When the book is spread open, the left and right pages are curved like parabolas that move away from each other with the boundary groove 14 as the center.

This curved surface shape has a large difference between the left and right sides depending on the spread position of the book, and for this reason, the deviation in the movement of the left and right curved surfaces due to the movement of the book causes one or both insertion block surfaces to Although the removal will be removed, the actual case will not be affected by this at all.

The present invention is also superior in that the portion inserted into the boundary groove 14 is thin and easy to pinch, but the force with which the book tries to close is due to the effect of increasing the clamping force of the protrusion a of the present invention in the boundary groove 14. Become.

And, by pressing the curved lines of the left and right pages into contact with the original second and fourth block surfaces, the triangular cylinder shape is maintained without any complicated shape processing or adhesives.

The usage method and advantages of the present invention are as described above, but in addition to the above-mentioned practical advantages, there are also the following decorative or emotional effects.

In this project, it is divided into four bronze planes and folded.

For this reason, the printed pictures attached to the surface of the bookmark of the present invention can be given meaning to each block surface.

The fourth embodiment of the present invention has the clearest outline, giving rise to the image of a totem pole.

Therefore, on the surface of each book of this project, you can make use of the child-friendly design of Totem Bonil by making various selections, such as a smiling face, as shown in Figure 4, and the third block that is visible when used as a page holder for a book. It is also very interesting to know which design is attached to the surface.

For adults, it is good to display pictures of beautiful women nude in sequence, and the contents of the printed designs on the surface can be endlessly interesting depending on the idea.

Therefore, as in the sixth and seventh embodiments of the present invention, the effect of linking with other products is also possible with a freshness not found in the conventional image of a bookmark.

゛In particular, as shown in the 7th embodiment, the use for high tags that are connected to various products such as price tags with thread etc. is particularly advantageous in that there is no damage to the main product if the main product is made of paper, and totem poles. By attaching a design pattern, a strong image is given to the psychology of the product purchaser.After the main idea is used as a tag, it can be used as a bookmark to attract attention. The effects of this will be immeasurable.

The novelty described above can be used for business cards, small calendars, etc., and has a very wide range of uses for advertising.
