Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present application relates to a file for storing relatively large paper sheets such as drawings or office paper.

Conventional technology and its problems Conventionally, as a file for storing relatively large sheets of paper such as design drawings, horizontally rectangular cardboard is made into a front cover of equal size by connecting two fold lines extending parallel to each other in the vertical direction. A three-fold cover body in which a back cover and an inner cover are integrally arranged is provided with fold-back pieces on the upper and lower edges of each cover and on the left and right side edges of the cover body, respectively, and the cover body and each fold-back piece are unfolded. There is a known structure in which a sheet of paper is placed on the inner surface of the cover body, each folding piece is folded inward and held so as to wrap around the periphery of the sheet, and then the cover body is folded in three. It is being

However, in the case of the above-mentioned file, if you take out the paper sheet with the cover main body unfolded, or if you view the drawing content written on it without taking out the paper leaf, the top and bottom edges and left and right side edges of the cover main body are Each flap must be opened individually,
Moreover, since the unfolded flaps fall inward due to their folds, it is necessary to simultaneously hold each flap in the unfolded state by hand. Not only is it extremely inconvenient to use when searching by flipping through the superimposed drawings, but if you want to view lower-level drawings that have been superimposed, you have to remove all higher-level drawings from the file. In addition, when storing or transporting files with drawings stored in them, the edges of the drawings touch the upper or lower edges of the cover body, resulting in folding of the cover, etc. As the corners of the curved ends are bent, the drawings are also bent, resulting in damage.

Objects, Examples, and Effects of the Invention Therefore, the first invention of the present application eliminates the upper and lower folding pieces of the cover located in the middle of the cover body, and the side folding pieces and the upper and lower folding pieces of the cover located on the left and right are interlocked. Further, in addition to the above-described structure, the second invention of the present application provides a structure in which the drawing is stored in a state where the drawing is stored between the left and right covers and the upper and lower folding pieces extending therefrom. The above-mentioned defects of the conventional cover are solved by providing a holding member that holds the cover at the center of the cover body away from the folded portion of the upper and lower folded pieces.

The drawings show an embodiment of the present application, in which 1 is a paper plate made of horizontally rectangular cardboard, and a front cover of equal size is created by arranging a pair of parallel fold lines 2, 2 and 3, 3 extending in the vertical direction. 4, a back cover 5, an inner cover 6, and narrow spine parts 7 and 8 located between these are integrally formed. The upper and lower folded pieces 1
0a, 11a, 10b, 11b are integrally extended, and left and right folding pieces 13a, 13b are integrally formed on the left and right side edges of the cover body 1 through two closely parallel folding lines 12, 12, respectively. It has been extended.
14a, 14b, 14c, 14d extend from the upper and lower edges of the left and right folding pieces 13a, 13b via fold lines 15, and have triangular notches 16 in the portions facing the corners of the cover body 1. , connecting pieces 14a, 14b, 14 whose apex facing diagonally is formed into an arc shape.
c and 14d, the folded pieces 13a and 10a,
13a and 10b, 13b and 11b and 13b and 1
1a are connected so as to rise slightly inward in the unfolded state, as shown in FIG. Reference numeral 17 denotes a holding member provided between the inner surface of each of the upper and lower folding pieces 10a, 10b, 11a, and 11b and the corresponding upper and lower inner surfaces of the front cover 4 and inner cover 6, and the holding member 17 is connected to the eighth As shown in the figure, a pair of fold lines 19, 19 parallel to the above-mentioned fold lines 9, 9 and with substantially equal intervals are attached to the outer edges of the fixing pieces 18 attached to the upper and lower positions of the inner surfaces of the front cover 4 and the inner cover 6. The extended free piece 20 and the ear portions 2 extend from the upper edges of the upper folded pieces 10a, 11a and the lower edges of the lower folded pieces 10b, 11b via fold lines 21, and extend from both side edges.
2 and 22 and a sliding part 23 that slidably holds the free piece 20, and when the upper and lower folded pieces 10 and 11 are folded back via the fold lines 9 and 9, the seventh As shown in the figure, the free piece 20 is also folded back via the fold lines 19, 19 while sliding against the sliding part 23, and the space 19' between the fold lines 19, 19 is changed to the space 9 between the fold lines 9, 9. ′ and parallel to each other while being located slightly inward from ′. 24 is a protective piece extending to the upper and lower edges of the back cover 5 located in the middle of the cover body 1, and is bent to have a triangular cross section at the upper and lower edges of the back cover 5 to form a protruding edge 25 in the form of a ridge. After forming, it is pasted on the inner surface of the back cover 5, and the upper and lower ridges 25,
Each inner edge of 25 substantially coincides with an extension line of each inner fold line 19 of the holding member 17. Reference numeral 26 indicates a folding allowance provided on the connecting piece 14 that is adhered to the upper and lower folding pieces 10 and 11, and 27 and 27 indicate magic tapes provided on the right folding piece 13a and the inner cover 6 that face each other when the cover body 1 is folded. A pair of locking pieces, 28
is a flexible binding piece provided at the center of the side edge of the inner cover 6.

However, when searching for paper sheets such as drawings,
When the front cover 4 is opened from the three-folded state shown in FIG.
4b also stands up, and due to this rising action, when the right folding piece 13a passes the approximately 90° angle standing position, the upper and lower folding pieces 10a, 10b are also forcibly moved by the reversing action of the connecting pieces 14a, 14b. As it is pushed open and the free piece 20 is also opened, the sliding part 23 slides and moves outward, and as a result, the right side of approximately 1/3 of the design drawing is exposed as shown by the imaginary line in Figure 3. Ru. Therefore, in this state, a desired drawing can be detected by searching the drawing title field written in the lower right corner of the drawing.
When the user wants to know the outline of the drawing detected in this state, the design drawing in the superimposed state is opened together with the inner cover 6. Then, as shown by the imaginary line in Figure 4, approximately 2/3 of the design drawing will be exposed, so
You can learn the gist of it.

In addition, when viewing the entire surface of the drawing P stored in the file of the present application, when the left folded piece 13b is opened from the state shown by the solid line in FIG. 4, the connecting pieces 14c and 14d integrated therewith Similarly to the above, the upper and lower folding pieces 10 and 11 are forcibly pushed open to unfold the file of the present invention as shown in FIG. 5, exposing the entire drawing, and the drawing can also be turned over in this state. Furthermore, a desired design drawing can be taken out from the binding piece 28 if necessary.

Next, when storing paper sheets such as drawings in the present file, as shown in FIG.
11a, 11b, 13a, 13b are unfolded, a plurality of design drawings are superimposed and placed on the inner surface of the cover main body 1, and if necessary, they are bound into the inner cover 6 via the binding piece 28. In this state, the design drawing placed on the inner surface of the cover body 1 is located between the upper and lower protruding edges 25, 25, and the upper and lower edges are protected by the protruding edges 25, 25. Next, the folded pieces 13b and 13a are first folded back inward together with each connecting piece 14 along the fold lines 12 and 12. Then, the fold line 15 is bent into a valley fold, and the connecting piece 14 becomes the upper and lower folded piece 1.
Polymerization is carried out as shown by the imaginary line in FIG. 5, with 0 and 11 inward. Next, the upper and lower folded pieces 10 and 11 are folded inward through the fold lines 9 and 9 to overlap on the plane shown in drawing P. In this case, as the upper and lower folding pieces 10 and 11 are folded inward, the free piece 20 is folded inward through the folding lines 19 and 19 while sliding within the sliding portion 23, and is superimposed on the drawing P. , in drawing P, its upper and lower edges are located at the center of the cover body 1, away from the folded portions of the upper and lower folding pieces 10 and 11. After that, the broken line 3,
As shown in FIG. 1, the inner cover 6 and the front cover 4 are sequentially closed through the cover 2, and the cover body 1 is folded into three. In this state, even if the file is put up for storage or transportation, the drawing P is still attached to the holding member 1.
7, the drawing will not be damaged even if the edges of the file are damaged. In the above, a case has been described in which the protruding edges 25 are provided on the upper and lower edges of the back cover 5 located in the middle, but in general, the files of the present invention are folded and arranged vertically on a bookshelf, etc. then,
In particular, since the lower edge of the design drawing is damaged, the protruding edge 25 must be provided at least at the lower edge of the back cover 5.

Effects of the invention As mentioned above, in a file consisting of a cover main body that has three covers integrally, the upper and lower folding pieces of the cover located in the middle are omitted, and the lateral folding pieces provided on the left and right covers are omitted. Since the folded pieces and the upper and lower folded pieces are connected by a connecting piece, when one folded piece is opened, the other folded piece is automatically opened, and the folded pieces are connected in the unfolded state. Since it is held by the intervening pieces, there is no need to hold each folded piece in the unfolded state as in the past, and you can search for the desired drawing by using the title column at the bottom right of the drawing or click the drawing. Since it does not require a large viewing area when viewing a summary of the drawings, it is extremely convenient to handle when searching for and viewing drawings. At least the lower edge of the back cover is provided with a protruding edge in the shape of a ridge that protrudes inward, so when the cover body is folded and placed vertically on a bookshelf for arranging, it can be easily placed under drawings, etc. It has the advantage that the edges are not exposed by the protruding edges, so there is no risk of damage to the lower edges of drawings, etc., and furthermore, the covers located on the left and right sides and the upper and lower folding pieces extending thereto are Since a holding member is provided between the cover and the cover, the drawing can be automatically held in the center of the cover body, which has the advantage of preventing damage to the edges of the drawing.
