The present invention relates to a corner structure of a hardcover of a hardcover book, and more specifically, to form an indentation in the corner of the hardcover book to bend easily when an impact is applied to prevent a safety accident.

Generally, a book is composed of a content sheet (body), an inner cover, and an outer cover. A hard cover book binding, usually made of thick paper, cloth, or leather, for long-term storage. ), And a distribution board for making covers with relatively soft and inexpensive paper.

Hardcovers have the advantages of high quality and durability because they are produced by the contents sheet and the cover and then cut together using a sheet of paper, but there is a risk that a safety accident may occur due to the edge of the book due to the hard cover.

In particular, children's books are made of hard paper in consideration of their rough handling, but most of them are made of hard hardcovers using so-called papers with multiple layers of paper glued together. to be. However, hardcovers have a sharp edge in the book, which is likely to cause safety accidents in children, and such safety accidents are often reported.

As an invention for preventing such a safety accident, the Korea Utility Agency Registration Utility Model Publication of the Korea Patent and Trademark Office creates a separate safety guard and puts it on the cover of the 'protective guard for injury by the edge of the book' (Registration No. 20-391973, Inventor; ) Is disclosed.

However, this method has a disadvantage in that costs must be increased because separate guards must be manufactured and replaced, and the guards must be manually inserted for each book.

The present inventors have led to the present invention, which is capable of mass production at low cost by improving the structure of the pointed portion of the edge of a hardcover book rather than such a separate guard attachment method.

An object of the present invention is to provide a corner structure of the cover to prevent a safety accident due to the edge of the book by improving the corner structure of the hardcover of a hardcover book.

Another object of the present invention is to prevent the safety accident due to the edge of the hard cover of the book, to maintain the appearance of the book.

It is another object of the present invention to provide a safety structure of a hard cover of a book which can be mass produced at a lower cost and at a lower cost.

The edge structure of the hardcover of the hardcover book to achieve the above object is characterized in that the flexure (屈伸 部) is formed on the corner to be easily folded or unfolded when a force is applied to the edge.

The bending function of the flexion part is implemented by bending, cutting, groove, partial incision, complete incision, etc. at the end of the corner, and selecting one of these methods or combining two or more methods, and the number of bending parts, etc. It is not limited to one place and can form in an appropriate number.

 In addition, in addition to the edge of the cover of the book spread portion (the content sheet of the book, that is, the portion where the text is spread), the burrs may be formed on the dorsal side when the back of the book is sharp. Such dorsal flexion needs to be formed when the book thickness of the hardcover is thin.

Hereinafter, the content of the present invention will be described in detail with reference to the accompanying drawings.

The general structure of the hardcover, as shown in Figure 1, is composed of a content sheet and a cover portion, the content sheet is composed of a coupling surface paper (3) for combining the content sheet 1 with the cover, the cover portion is the design of the cover On the printed outer cover 5, the wick 10 (hereinafter referred to as 'front wick') of the front cover, the wick 12 (hereinafter referred to as the 'wick') constituting the book, and the wick of the back cover ( 14) (hereinafter referred to as 'back wick', collectively referred to as 'wick (7)') are placed and bonded in sequence at regular intervals and rolled up the edge paper of the outer cover (5) these wicks (7) It consists of a form that wraps around.

When the cover part thus produced is bonded to the mating face paper 3 of the contents sheet, the bookbinding of the hard cover book is completed.

The flexure 9, which is a feature of the present invention, is first constructed by a method of forming one or more bends f in the four corners 7 'of the mark as shown in FIG. Bending refers to a method of forming a bone (hereinafter, referred to as a bend) by pressing a portion to be folded with a non-sharp blade or the like without cutting or cutting paper.

In the present embodiment, the shape of the bent portion f was formed with an oblique line of 45 °, and two positions were formed inside and outside with respect to the point where the vertex of the cross section of the inner portion of the contents meets the inner surface of the corner of the cover portion.

However, the bent portion f is not limited to one, and the angle of the shape may not be 45 degrees, and the position is not limited to the point of this embodiment. However, at least one or more is preferably formed outside the vertices of the cross section of the inner sheet which is not covered with a cover, so that when the force is applied from the outside, it is preferably folded at least 90 °.

In addition, in the present embodiment, the bent portion f is formed on the wick 7 and then wrapped and bonded with the outer cover 5, but the bent portion f may be formed after being wrapped with the outer cover 5 and bent. The portion f may be formed only inside or outside the cover edge, or both.

The stretched part 9 may be formed by cutting out a part of the edge portion 7 'as shown in FIG. 2 (b) and (d). The shape of the cross section may be any shape as long as the shape is capable of alleviating the sharp portions of the corner portion 7 'such as a straight cut surface (a), a rounded cut surface (b), and a heart-shaped cut surface (c).

In this case, the cut edges are wrapped only with the outer cover 5 without a wick to maintain the original shape of the cover, and only the edges without the wick are easily flexed or deformed when the outer shock is applied.

In FIG. 2 (e), the flexures 9 can be easily bent by forming grooves h in the corners 7 ′. (B) shows the method of cutting to form the cutout (s), and (g) uses the method of cutting to form the cutout (d).

All of these methods are preferably formed in the wick 7, and the number and position of the grooves and the like are the same as those of the bent portion f.

However, except for the methods of (B) (C) (D) and (G), all forms of connecting parts shall be left so as not to separate the corners during the manufacture of the cover.

It is also possible to combine any one or more of these methods. For example, the extension part of (a) and the cross-sectional shape of (b) can also be combined.

On the other hand, as shown in Figures 3 and 4 when the thickness of the book is thin, both ends of the book 18, which is opposite to the spreading portion 16 is sharpened, such a book is located in the back of the book 18 Both ends of the paper 12 can be formed in the above-described method, that is, a bend (j-section) by bending, cutting, partial incision, groove, complete incision.

In this case, the position and direction of bending and the like is preferably formed in the horizontal direction near the point where the upper and lower ends of the content sheet meet when the book lamp 18 of the book is placed upright on the bookshelf. It doesn't happen.

According to the operation of the corner safety structure of the book of the present invention, when the corner of the book hits the human body or an external object, the sharp edge is easily folded or unfolded due to the flexing portion 9 formed at the corner of the hard cover, thereby alleviating the impact. This will prevent safety accidents.

In addition, the flexural structure according to the present invention maintains the original appearance of the book even if formed on the wick (7) of the outer cover (5), or bent at the corner of the outer cover (5), even in the bookbinding process It is possible to work by making it easy to manufacture.

While various embodiments have been described herein in order to disclose the present invention, the scope of protection of the present invention is not limited to the above description, but only by the description of the claims of the present invention.

According to the present invention, when the corner hits the human body due to the bending function of the edge formed on the edge of the book, the sharp edge portion is easily bent or unfolded, thereby preventing a safety accident.

The edge structure according to the present invention is to form a bent portion on the wick or to form a cut surface on the wick and wrapped with an outer cover, so that the appearance of the book is maintained as it does not hurt the aesthetics.

The edge safety structure according to the present invention has the advantage that the simultaneous or sequential work in the bookbinding process is easy to mass work, and thus the cost is low.
