The file disclosed in Patent Document 1 can stand on its own in a double-page spread, but since the lower part of the front cover and the back cover is folded outward, the lower part of the document P is not supported by the cover and can maintain a stable posture. There was a possibility that it would not. In addition, the file disclosed in Patent Document 2 cannot stand on its own in a double-page spread, and the system notebook disclosed in Patent Document 3 is equipped with a double-page spread with a smaller number of formats on one side of the entire double-page spread. is.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a cover which can stand on its own in a state where two pages of a double-page spread can be easily viewed.

A cover body according to the present invention has a first cover sheet and a second cover sheet that can be folded so as to be opened and closed. A first cover-side sliding portion accommodated in the double-structured portion so as to be slidable in the double-structured portion of the first cover, and a double-structured portion accommodated in the double-structured portion of the second cover so as to be slidable in the double-structured portion. a second cover-side sliding portion, and a leg connected to the cover portion so as to be able to be pulled out from the first cover and the second cover. Further, the legs are pulled out from the first cover and the second cover and support the cover so that the cover is independent when the cover is opened.

By providing legs that can be pulled out from the cover separately from the cover, the legs can support the entire cover while maintaining the spread state in which the display is opened. Therefore, the two-page spread can stand on its own in an easy-to-view state.

Further, the legs are composed of a first leg plate connected to the first cover-side sliding portion via the first fold line and a second leg plate connected to the second slide portion via the second fold line. With the legs pulled out from the first cover and the second cover, and in the state where the cover is opened, the first fold and the second fold are folded respectively, and the first leg plate, the second leg plate and the cover A portion of the portion may form a substantially cone-shaped side surface. For example, with such a substantially conical shape, the cover body can stably stand on its own.

In addition, the leg has a slit extending from the first leg plate and the second leg plate, the fold extending from the approximate end of the slit is folded into a mountain fold, and the fold extending from the intermediate portion of the slit is folded into a valley fold and folded. A tongue portion may be formed that The half-folded tongue portion acts to resist external force in the direction in which the first leg plate and the second leg plate close, and can maintain the above-described substantially cone shape.

In addition, the cover portion has a spine continuous between the first cover and the second cover, and the legs include a third leg plate connected between the first leg plate and the second leg plate, and a connecting portion that rotatably connects the third leg plate to the spine. In this way, the direction in which the legs should be drawn out from the cover is guided, making it easier to use.

In addition, when the tongue portion is folded in half, the edges of the tongue portion on the slit side may abut on the facing positions of the cover portion, particularly the cover body having the back cover. If so, it may be in contact with the back cover. In this way, the tongue portion can reinforce the substantially cone-shaped structure described above.

In addition, the first cover has a first restricting portion that engages with the first cover-side sliding portion to restrict the sliding range in the double structure portion of the first cover, and the second cover has a sliding range. The double structure portion of the second cover may have a second restricting portion that engages with the second cover-side sliding portion to restrict the sliding range. In this way, the size of the legs to be pulled out from the cover can be determined appropriately, making it easier to use.

Alternatively, a file including the above-described cover sheet may be provided. Covers can be applied to files, for example. A booklet, a book cover, a photo frame, a smart phone case, a tablet case, or the like having the cover body described above may be provided.

The configurations described above can be combined as much as possible without departing from the technical idea of the present invention.

According to the invention of the present application, it is possible to provide a cover body that can stand on its own in a state where the two-page spread can be easily viewed.

The present invention will be explained based on the drawings. The embodiments described below are examples of the present invention, and the present invention is not limited to the embodiments.

FIG. 1 is a diagram showing a state in which a file is opened and made independent according to the embodiment. File 1 is a clear file (clear book) in which, for example, a plurality of pockets are bound between covers 2 . The cover body 2 is made of resin, for example. Further, the cover body 2 includes a cover portion 21 corresponding to the cover of the file 1 and leg portions 22 supporting the file 1 in a self-supporting state in a double-page spread.

The cover section 21 includes a first front cover 211, for example, a second front cover 212, and a back cover 213, for example. Further, the cover portion 21 has a double structure in which the edges of the two panels are adhered together by, for example, welding. Between the two panels, legs 22 for pulling out from the cover part 21 and supporting the cover part 21 in an independent state can be folded and accommodated.

The legs 22 include a first leg plate 221 overlapping the first cover 211 in the folded state, a second leg plate 222 overlapping the second cover 212 in the folded state, and a second leg plate 222 overlapping the back cover 213 in the folded state. and a tripod plate 223 . Further, when the leg part 22 is pulled out from the cover body 2 and the file 1 is opened, a part of the first cover 211 and the second cover 212 opened in a plane, a first leg plate 221, and a second leg plate 222 are displayed. form three faces that are generally pyramidal (eg triangular pyramidal) shaped. The cone shape allows the file 1 to stand on its own stably. An inverted V-shaped slit is provided across the first leg plate 221 , the third leg plate 223 and the second leg plate 222 . The above-described cone shape can be reinforced by folding the tongue portion 224 formed by the slit into a valley fold at the center and a mountain fold at the outer side, like folding of origami paper. In addition, as shown in FIG. 1, one or more valley folds are provided between the mountain folds provided on each of the first leg plate 221 and the second leg plate 222 which are bent to form an angle, and the tongue portion 224 is inserted. In the present embodiment, folding in such a manner is referred to as "middle folding".

FIG. 2 is a diagram for explaining the configuration of the cover. FIG. 2 shows an example of a plan view in which the file 1 is opened. In FIG. 2, the internal configuration of the cover 2, which has a double structure, is indicated by broken lines. Further, in the self-supporting state, mountain folds are indicated by one-dot chain lines, and valley folds are indicated by two-dot chain lines. The creases indicated by one-dot chain lines and two-dot chain lines are linearly thinned to facilitate folding. In addition, locations to be adhered by welding, for example, are indicated by fine dots.

The cover section 21 has a first cover 211, a second cover 212 and a back cover 213 which are formed by welding the edges of an inner panel 214 and an outer panel 215 together. Also, the leg portion 22 is sandwiched between the inner panel 214 and the outer panel 215 . In addition, in FIG. 2, the leg portion 22 is hatched. As described above, the leg portion 22 includes the first leg plate 221 overlapping the first cover 211 , the second leg plate 222 overlapping the second cover 212 , and the third leg plate 223 overlapping the spine 213 . Further, the outer panel 215 has cutouts extending from the middle of the back cover 213 to near the center of the lower end of the first cover 211 and near the center of the lower end of the second cover 212 to form an opening. Further, the leg portion 22 is exposed from the opening portion of the outer panel 215 .
In addition, the third leg plate 223 has an extension (also referred to as a “connecting portion”) 2231 extending in a strip shape toward the upper portion of the spine 213 , and the edge of the extension 2231 is attached to the inner panel 214 of the spine 213 . part is welded. A portion of the leg portion 22 other than the extended portion 2 is not adhered to the cover portion 21, and between the extended portion 2231 and other portions (that is, the edge of the extended portion 2231), for example, a thinned hinge is provided. A portion 2232 is formed. Therefore, when the file 1 is closed, the leg portion 22 can slide (rotate) around the hinge portion 2232 , and the user can pull out the leg portion 22 from the cover portion 21 .

Also, the first leg plate 221 is connected to the first cover-side sliding portion 2212 held between the inner panel 214 and the outer panel 215 through the valley fold line 2211 even at the drawn-out position when the cover portion 21 is drawn out. is set. The first cover-side sliding portion 2212 has a restricting portion 2213, which is a convex portion for restricting the rotating range, on the free end side corresponding to the outer peripheral side of rotation with the hinge portion 2232 as the fixed end. Similarly, the second leg plate 222 is connected to the second cover-side sliding portion 2222 that is held between the inner panel 214 and the outer panel 215 even in the pulled-out position pulled out from the cover portion 21, and the valley fold line 2212. It is connected. The second cover-side sliding portion 2222 has a restricting portion 2223, which is a convex portion for restricting the rotation range, on the free end side corresponding to the outer peripheral side of rotation with the hinge portion 2232 as the fixed end.

Further, the cover body 2 includes regulating members 231 and 232 between the inner panel 214 and the outer panel 215 that regulate the range in which the legs 22 slide. In FIG. 2, the regulating members 231 and 232 are represented by thin dashed lines. Further, the restricting member 231 is provided at a predetermined position inside the first cover 211 and welded to the inner panel 214, for example. The regulating member 232 is provided at a predetermined position within the second cover 212 and welded to the inner panel 214, for example. Also, the restricting portions 2213 and 2223 of the leg portion 22 are housed between the inner panel 214 and the restricting member 231 or 232 . The regulating members 231 and 232 are provided with regulating portions 2311 and 2312 having concave edges at the edges of the portion bonded to the inner panel 214 and engaged with the regulating portions 2213 and 2223 of the leg portion 22 to regulate sliding. include.

In addition, the leg plate 22 is provided with an inverted V-shaped slit 225 over the first leg plate 221 , the third leg plate 223 and the second leg plate 222 . A region surrounded by the slit 225 and the valley fold line extending from the end of the slit to the third leg plate 223 is also called a tongue portion 224 . When the cover body 2 is open, the tongue portion 224 is folded inwards and folded along the boundary between the third leg plate 223 and the first leg plate 221 and the boundary between the third leg plate 223 and the second leg plate 222. It can be folded into a valley fold and the outer edge of the tongue portion 224 can be folded into a mountain fold.

<How to use>
3 to 5 show the procedure for transforming a file. FIG. 3 is a perspective view showing a closed state of the file. When the file 1 and the cover 2 are closed, the legs 22 are accommodated in the cover 21, and the entire file 1 is in the shape of a substantially rectangular parallelepiped booklet. A part of the leg 22 is exposed from the opening of the outer panel 215 of the cover 21, so that the user can pinch the leg 22. As shown in FIG.

FIG. 4 is a perspective view showing a state in which the legs are pulled out from the cover. When the user pinches and pulls out the leg portion 22 , the leg portion 22 (the third leg plate 223 ) rotates around the hinge portion 2232 . Further, the restricting portions 2311 and 2312 of the restricting members 231 and 232 shown in FIG. 2 and the restricting portions 2213 and 2223 of the leg portion 22 are engaged to restrict the rotation of the leg portion 22, as shown in FIG. It will be in a withdrawal state like this.

FIG. 5 is a perspective view showing a state in which the cover body is opened. When the first cover 211 and the second cover 212 are opened, the first leg plate 221 and the second leg plate 222 of the leg 22 are folded along the valley fold lines 2211 and 222 .
At 21 each is bent into a valley fold, and the legs 22 protrude in the direction of the spine of the file 1 . At this time, by placing the lower ends of the first leg plate 221, the second leg plate 222 and the third leg plate 223 on a flat surface, the file 1 stands on its own with the cover portion 21 in a spread state with a predetermined angle.

Further, the user folds the third leg plate 223 and the first leg plate 221 along the boundary between the third leg plate 223 and the first leg plate 221 and the boundary between the third leg plate 223 and the second leg plate 222 into a valley fold, and folds the third leg plate 223 and the edge of the slit 225 can be folded in a mountain fold. At this time, the state shown in FIG. 1 is obtained. In addition, the upper end of the tongue portion 224 defined by the slit 225 is located at the opposite position on the cover portion 21 (that is, the spine where the upper end of the tongue portion 224 folded inwardly into the cone shape described above faces). Since the tongue 224 abuts against the cover 213) and resists the external force acting in the direction of closing the leg 22, the open state of the file 1 can be stably maintained.

FIG. 6 is a perspective view of a self-supporting file in a double-page spread, viewed from the inside. In the example of FIG. 6, a plurality of pockets 3 are bound between the first cover 211 and the second cover 212 . The file 1 stands on its own while the first cover 211 and the second cover 212 are opened in opposite directions by approximately 180 degrees. Such a file 1 is easy to see and highly convenient for the user, especially when opening documents while writing or cooking, or when using it as a music stand while playing a musical instrument.

When closing the file 1 in the state shown in FIGS. 1 and 6, the user folds the first cover 211 and the second cover 212 with the pocket 3 inside. At this time, the first leg plate 221 engaged with the restricting member 231 is pulled by the first cover 211, the second leg plate 222 engaged with the restricting member 232 is pulled by the second cover 212, and the tongue portion 224 is split. Since the folding is released, the state shown in FIG. 4 is restored. The user then pushes the pulled out legs 22 back between the inner panel 214 and the outer panel 215 of the cover section 21, and the file 1 returns to the state shown in FIG. In this way, the file 1 can be folded into a size similar to that of a general file, and can be easily carried.

<Modification>
The cover body 2 may not include the back cover 213, and the first cover 211 and the second cover 212 may be arranged in series. In this case, the leg portion 22 does not have the third leg plate 223, the extending portion 2231, and the hinge portion 2232. Therefore, to prevent the leg 22 from sliding to an unintended position between the inner panel 214 and the outer panel 215 of the cover section 21, for example, the upper portion of the leg 22 in FIG. and the sliding range may be restricted. By adhering the inside of the double-structured cover portion 21 so as to guide the legs 22 between the retracted state and the pulled-out state, the operation is facilitated for the user. Also, in this case, the upper end of the half-folded tongue portion 224 abuts on the facing position of the cover portion 21 (specifically, the crease between the first display 211 and the second cover 212). Also in this case, since the tongue piece 224 resists the external force acting in the direction of closing the leg 22, the file 1 can be maintained in the open state.

The cover body 2 can also be used for covers other than clear files. FIG. 7 is a perspective view showing an example of a self-supporting ring binder. The ring binder 10 includes the cover 2 and a plurality of rings 4 described above. Note that the number of rings 4 is not particularly limited. In addition, the above-described cover body 2 may be applied to files with various bindings such as lever files and pipe files, booklets, book covers, photo frames, smartphone cases, tablet cases, etc. (not shown). . For example, the smartphone case may hold a smartphone on one of the first cover 211 and the second cover 212 of the cover body 2 and the other may function as a cover.

The contents described above can be combined as much as possible without departing from the technical idea of the present invention.
