Structure for book cover

Abstract

An improved structure for book cover includes a cover layer, a left positioning plate and a right positioning plate, wherein the left and the right positioning plates are disposed above the cover layer and the edges of the cover layer can be folded inwardly for being adhered or stitched at the edges of the left and the right positioning plates, and the left and the right positioning plates respectively have a protruded left binding portion and a protruded right binding portion which both have plural holes corresponding to each other for fixing loose leaf papers between the left and the right positioning plates directly by a spiral so as to form a book. Through the improved structure of book cover in the present invention, the manufacturing process can be simplified and the cost of labor and material can be saved.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

The foregoing aspects and many of the attendant advantages of this invention will be more readily appreciated as the same becomes better understood by reference to the following detailed description, when taken in conjunction with the accompanying drawings, wherein:

FIG. 1 is a 3D decomposition drawing showing a preferred embodiment in the present invention before processing;

FIG. 2 is a 3D drawing showing a preferred embodiment in the present invention before processing;

FIG. 3 is a 3D drawing showing a preferred embodiment in the present invention after processing;

FIG. 4 is a 3D drawing showing the folding in a preferred embodiment of the present invention; and

FIG. 5 is a 3D drawing showing the using status in a preferred embodiment of the present invention.

DESCRIPTION OF THE PREFERRED EMBODIMENT

Please refer to FIGS. 13 which are respectively showing a 3D decomposition drawing before processing, a 3D drawing before processing and a 3D drawing after processed for a preferred embodiment in the present invention.

In one embodiment according to the present invention, the book includes a cover layer 30, a left positioning plate 10 and a right positioning plate 20, wherein the left and the right positioning plates 10, 20 are located on the cover layer 30, which has a relatively larger area, so that a space 35 can be reserved between the left and the right positioning plates 10, 20 without exceeding the area range of the cover layer 30, and further, even a closest edge of the left and the right positioning plates 10, 20 to that of the cover layer 30, a distance will still be kept therebetween so that a portion of the cover layer 30 can be folded up inwardly to cover the edges of the left and the right positioning plates 10, 20 and after being adhered or stitched (or high frequency melted) on the left and the right positioning plates 10, 20, an upper folded edge 31, a lower folded edge 32, a left folded edge 33 and a right folded edge 34 can be formed. The edges of the left and the right positioning plates 10, 20 which are adjacent to each other respectively have a protruded left binding portion 11 and a protruded right binding portion 21 which both have plural holes 12 corresponding to each other, wherein the length of the left and the right binding portions 11, 21 is less than the distance between the upper folded edge 31 and the lower folded edge 32.

As using or binding, according to this embodiment, it only needs to outwardly fold the cover layer for lapping the left and the right positioning plates 10, 20 (as shown in FIGS. 4 and 5), and then the binding portions 11, 21 can be exposed at the outer side and also the holes 12 so that loose leaf papers 50 can be bound between the left and the right positioning plates 10, 20 through a spiral 40. Therefore, a book is formed.

It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.

Claims

1. An improved structure for book cover, comprising: a left positioning plate;a right positioning plate; anda cover layer, wherein the left and the right positioning plates are located on the cover layer, which has a relatively larger area, so that a space is reserved between the left and the right positioning plates without exceeding the area range of the cover layer, and a distance between any edge of the left and the right positioning plates and an edge of the cover layer closest thereto is kept for defining a folding border so as to facilitate the cover layer to be folded up inwardly to cover the edges of the left and the right positioning plates, and the edges of the left and the right positioning plates which are adjacent to each other respectively have a protruded left binding portion and a protruded right binding portion which both have a plurality of holes corresponding to each other.

2. The improved structure for book cover as claimed in claim 1, wherein the length of the left and the right binding portions is less than that of two edges of the left and the right positioning plates which are adjacent to each other.

3. The improved structure for book cover as claimed in claim 1 further comprising a spiral for binding loose leaf papers between the left and the right positioning plates so as to form a book.

4. The improved structure for book cover as claimed in claim 1, wherein the folding border is adhered to the edges of the left and the right positioning plates.

5. The improved structure for book cover as claimed in claim 1, wherein the folding border is adhered to the edges of the left and the right positioning plates by stitching.

6. The improved structure for book cover as claimed in claim 1, wherein the folding border is adhered to the edges of the left and the right positioning plates by a high frequency melting.
