Description

{Books convenient to unfold}

The present invention is to prevent a book opened for reading from being folded. By constituting a plurality of holes satisfying the conditional formulas optimized for the bookbinding portion of the book and minimizing the elasticity of the portion, It is an invention on a book.

Generally, the book is bound with glue, which has the disadvantage that the book opened for reading is folded again.

Patent Registration No. 10-0898101 relates to a book which prevents the book from spreading smoothly and covering the page by itself. In order to realize this, the adhesive portion has a plurality of grooves perpendicular to the direction in which the book is spread on the portion to be bonded to the mark portion. Therefore, when the book is opened, the plurality of groove intervals are reduced, and the opposite side of the groove is convex, thereby preventing the page from being covered by itself.

Japanese Laid-Open Patent Publication No. 10-1999-007615 utilizes the flexibility of the cloth by using a plain cloth which is discharged in place of Ceyang yarn and the like and keeps the unfolded state. In addition, if you go back to the original, you will be able to maintain the robustness of the existing book binding, improve the weakness of damage to the product, and reduce the bookbinding process one step.

Registration Utility Model No. 20-0403435 is intended to improve the existing book shape to facilitate reading, and it is easy to turn the book and the page movement is flexible, so that a document or page fixing device is not required. When the book is opened, the pages are pushed into the empty space, so that the book is not covered again, and is completely opened without a special fixing device.

The public utility model publication 20-2008-0002476 is constructed so that the cover and the inlay of the book can easily be turned over to make a well-turned book that can prevent the book from being wrinkled or stained and extend the life of the book . In order to achieve this, an inlay group in which one edge is bound with an adhesive, and an outer cover surrounding the inlay group, wherein the inlays have a first portion bounded by an adhesive and a second portion extended from the other side of the first portion, And a printing portion in which a type is printed.

However, the above methods have a problem that it is difficult to insert a title, an author, a publisher or the like into a side cover part, the manufacture is complicated, the volume of the book becomes larger as the out-of-groove part protrudes, and the book can not be unfolded uniformly.

Further, openings 70-1 and 70-2 may be further formed on the upper surface 12 and the lower surface 14, and the first through n-th holes may be additionally formed on the cover.

The present invention constitutes the first to nth holes that satisfy the conditional formulas optimized for the cover and the inlay of the book, so that the title, author, publisher, etc. of the book can be easily inserted into the side of the cover, , The book can be evenly spread without increasing the volume of the book.

BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a view showing an embodiment of a book which is easy to open according to the present invention. Fig.
Fig. 2 is a view for showing in detail the hole configuration of an embodiment of an inlay of an easy-to-open book of the present invention.
Fig. 3 is a view showing an example of the change in elasticity according to the number of holes constituting the easy-to-open book of the present invention. Fig.
4 is a comparative example of an embodiment of the present invention and a conventional general book.
FIG. 5 is a view showing another embodiment of the present invention. FIG.

Hereinafter, an easy-to-open book according to a preferred embodiment of the present invention will be described with reference to the drawings.

1 and 2, includes a cover including a top surface 12, a bottom surface 14, and a surface 20 constituted by a portion to be bound by an adhesive, and a plurality of inks 10 And a plurality of first holes 30-1 to n-th holes 30-n are formed in the plurality of inlaids 10, the center of which is located on the straight line 40. [

Here, a distance from the top surface 12 to the center of the first hole 30-1 is a, a distance from the bottom surface 14 to the center of the n-th hole 30-n is d, The distance from the surface 20 to the center of the first hole 30-1 to the n-th hole 30-n is b and the distance from the first hole 30-1 to the nth hole 30- n is defined as c and the interval between each of the first holes 30-1 to 30-n with respect to the radius r is defined as c, the minimum value of c is 1.2 mm The distances a, d, b, the radius r, and the spacing c are set to satisfy the following conditional expression (1) to prevent the contents of letters, pictures, photographs, ] To [conditional expression 5].

a = 20 占 10 mm [Conditional expression 1]

d = 20 占 10 mm [Conditional expression 2]

b = 10 5 mm [Conditional Expression 3]

r = 3 占 1.5 mm [Conditional expression 4]

c = (r / 2) 占 9 mm [Conditional expression 5]

FIG. 3 is a graph showing how the elasticity of the national book (A4) book changes as the number of holes having a radius of 3 mm, which is formed by a distance from the center of the hole to the center of the hole is 10 mm. The degree of change of the elasticity is determined by setting the reference value such as the physical quantity to be compared, and applying the p.u. (percent unit) method indicating the degree of change in comparison with the reference value. If the elasticity of the inlay 10 is 1 pu and the number of holes is gradually increased to see how the elasticity of the inlay 10 changes as the number of holes increases, It can be seen that it gradually decreases and then maintains a constant value.

Referring to FIG. 3, the elasticity of the inlay is no longer reduced after 37 holes. This means that the hole should be limited to a specific number in constituting the hole and that the minimum interval between adjacent holes can be a reference thereof. It can be seen from FIG. 3 that the minimum spacing between adjacent holes is 1.2 mm, and when 37 holes are formed at equal intervals of 3 mm in radius, the above conditional expressions are also satisfied.

In particular, the first holes 30-1 to the n-th holes 30-n may be formed not only in a circular shape but also in an elliptical shape, a polygonal shape, or the like. Here, when the hole is an ellipse, r represents a long radius, and when the hole is a polygon, it represents the longest distance from the center point to each vertex.

5 shows another embodiment of the present invention in which openings 70-1 and 70-2 having a radius of 1.2 times the radius of the hole (sd = 1.2xr) are formed on the upper surface 12 and the lower surface 14 of the book, ) So that the center of the opening is located on the straight line 40 from the center line of the first hole 30-1 to the n-th hole 30-n. Like the hole, the hole has a shape selected from a circle, an ellipse, and a polygon, and may have a hole or other shape.

The first holes 30-1 to the n-th holes 30-n may be additionally formed on the cover, and the openings 70-1 and 70-2 may be additionally formed.

The holes formed in the adjacent inlaid regions may be staggered in the range of the above-described conditional expressions, and the shapes of the holes may be configured differently for each page.
