Description

[Technical Field]

[0001] The present invention relates to a foldable clear file for storing documents and the like. [Background Art]

[0002] Clear files are used to prevent documents and the like from being soiled or creased. In many cases, a common method for storing clear files is to stand them on a bookshelf or sandwich them between books to prevent them from falling over.

[0003] Consideration is given here to the case where documents are put into a clear file and stored by standing the file on a bookshelf. In this situation, there are very few cases where the clear file does not bend and can be stood while maintaining a flat state; in most cases, the edge of the clear file bends, causing the documents inside to also bend. To solve this problem, as disclosed in Patent Document 1, there is described a clip-type binder that can hold magazines, files, documents and the like, deform into a three-dimensional shape, and stand on its own on a desk or table. More specifically, Patent Document 1 discloses a clip-type binder in which a spring is bent into a rounded semicircular shape to provide a space for inserting and holding magazines, files, documents and the like, the spring is folded back into a rounded semicircular shape, and a portion formed by bending outward into a round shape to be opened is provided at the folded end to facilitate insertion of magazines, files, documents and the like.

[0004] [Patent Document 1] Japanese Unexamined Patent Application Publication No. 2013-180571 Problem to Be Solved by the Invention

[0005] However, the clip-type binder described in Patent Document 1 needs to be removed when taking documents out or when storing it by placing it between books. Also, since Patent Document 1 is semi-circular and the clip-type binder is attached only to the center of the clear file, it cannot be said that it can stand upright stably.

[0006] Now, let's consider why the clip-type binder in Patent Document 1 is detachable. This is because while the clip-type binder is useful when you want to stand up clear files, it gets in the way when you put clear files between books or put them in a bag.

[0007] Therefore, the present invention aims to provide a foldable clear file that enhances stability when standing upright by combining two clear files, and that can be easily transformed into a flat shape without removing any parts when the three-dimensional shape necessary for standing upright becomes inconvenient.

[0008] The foldable clear file of the present invention is It consists of a first clear file and a second clear file, which are two clear files of the same size stacked on top of each other. The first clear file and the second clear file are connected at least at one end so as to form a three-dimensional shape. The centroid of the solid enclosed by the first clear file and the second clear file is projected onto a plane that includes the bottom edges of the first clear file and the second clear file, and the centroid projected onto the plane lies inside the region enclosed by the bottom edges of the first clear file and the second clear file.

[0009] Furthermore, the foldable clear file of the present invention is It comprises a first clear file and a second clear file, which are two clear files of the same size stacked on top of each other, and four leaf springs. The first clear file and the second clear file are connected at their left and right ends, respectively, and are deformable so that they can be combined to form a cylindrical shape. The leaf springs are attached to the upper and lower inner ends of the first and second clear files, respectively. Before deformation, these leaf springs are semicircular in shape, and they can be deformed into a straight shape by applying force in a direction perpendicular to the straight line connecting the ends of the leaf springs.

[0010] Furthermore, the foldable clear file of the present invention is A first clear file and a second clear file made by stacking two clear files of the same size, and a bottom section, The first clear file and the second clear file are connected at one end and can be deformed so that they combine to form a triangular prism shape. The initial shape of the bottom surface is rectangular, and it can be deformed by folding by applying force in a substantially horizontal direction to the first and second clear files. Effect of the Invention

[0011] According to the present invention, by combining two clear files, stability when standing upright is increased, and when the three-dimensional shape required for standing upright becomes an obstacle, it can be easily transformed into a flat shape without having to remove the parts.

[0013] The embodiments of the present invention will be described in detail below, but the description of the constituent elements described below is just one example (representative example) of the embodiments of the present invention, and the present invention is not limited to the following unless its gist is changed. Components having the same function are denoted by the same reference numerals in the drawings, and their detailed descriptions are omitted.

[0014] (1. Regarding the overall structure) First, the overall structure of the foldable clear file according to an embodiment of the present invention will be described. As shown in Figure 1, the foldable clear file 1 comprises a first clear file 11, a second clear file 12, and four leaf springs 21, 22, 23, and 24. Also, as shown in Figure 1, the leaf springs 21, 22, 23, and 24 are attached to the upper and lower inner ends of the cylindrical first clear file 11 and second clear file 12, respectively.

[0015] The first clear file 11 and the second clear file 12 are described as clear files made of commonly used plastic material, and the leaf springs 21, 22, 23, and 24 are described as leaf springs made of stainless steel. Of course, the first clear file 11 and the second clear file 12, and the leaf springs 21, 22, 23, and 24 can all be made of materials appropriate for their intended use. Also, the size of the first clear file 11 and the second clear file 12 can be an appropriate size depending on their intended use, such as A4 or B5.

[0016] In the present embodiment, the first clear file 11 and the second clear file 12 are connected at the vertical portion on the binding side, and are connected to each other at the vertical portion of the opening portion between the inner surfaces of the cylinder. The leaf springs 21, 22, 23, and 24 are attached to the upper end and the lower end inside the cylindrical first clear file 11 and the cylindrical second clear file 12, respectively. As shown in FIG. 2, the leaf spring 21 and the leaf spring 22, and the leaf spring 23 and the leaf spring 24 are connected to each other respectively, and the connection positions thereof coincide with the connection part of the first clear file 11 and the second clear file 12.

[0017] In the present embodiment, as shown in FIG. 1 and FIG. 2, the foldable clear file 1 has a cylindrical shape. However, the intent of the present invention lies in that the foldable clear file 1 can stand on its own, therefore, it is only required that the center of gravity of the three-dimensional body surrounded by the portion enclosed by the upper sides of the first clear file 11 and the second clear file 12, the portion enclosed by the lower sides of the first clear file 11 and the second clear file 12, the first clear file 11 and the second clear file 12 is projected onto a plane including the lower sides of the first clear file 11 and the second clear file 12, and the projection point is located inside the region enclosed by the lower sides of the first clear file 11 and the second clear file 12. Therefore, the foldable clear file 1 may have any shape as long as the shape satisfies the above condition.

[0018] (2. Usage Method of the Foldable Clear File) Next, with further reference to FIG. 3 to FIG. 5, the usage method when using the prototype of the foldable clear file 1 shown in FIG. 3 will be described.

[0019] First, when placing a document into the foldable clear file 1, as shown in FIG. 5, a force is applied from the outside of the cylindrical foldable clear file 1 in the direction to make the first clear file 11 and the second clear file 12 form a planar shape, so as to flatten the foldable clear file 1. By doing so, it becomes easier to insert a document into the foldable clear file 1 than when the foldable clear file 1 is in a three-dimensional state.

[0020] After placing documents in the foldable clear file 1, if you want the foldable clear file 1 to stand on its own, you can release the pressure you applied to make the foldable clear file 1 three-dimensional and stand on its own as shown in Figure 4.

[0021] Additionally, if you want to store the foldable clear file 1 by placing it between books or inside a bag, you can do so by applying pressure while placing it between books or inside a bag.

[0022] (3. Regarding shapes derived from this embodiment) The intent of the present invention is that the foldable clear file 1 is self-standing. Therefore, the center of gravity of the solid enclosed by the first clear file 11 and the second clear file 12 is projected onto a plane that includes the lower edges of the first clear file 11 and the second clear file 12, and that point must be inside the region enclosed by the lower edges of the first clear file 11 and the second clear file 12. Therefore, the shape of the foldable clear file 1 can be any shape as long as it satisfies this condition. Accordingly, an example of a different shape derived from this embodiment will be described.

[0023] Figures 6 and 7 show a foldable clear file 2, which is another embodiment of the present invention. As shown in Figures 6 and 7, the foldable clear file 2 connects the lateral openings of the first clear file 11 and the second clear file 12, and attaches the bottom portion 31 between the lateral binding portions of the first clear file 11 and the second clear file 12.

[0024] The first clear file 11 and the second clear file 12 are described as clear files made of commonly used plastic material, and the joining part 31 is described as being made of the same plastic material as the first clear file 11 and the second clear file 12. Of course, the first clear file 11, the second clear file 12, and the bottom part 31 can all be made of appropriate materials depending on the intended use. In particular, the bottom part 31 is an important part for making the foldable clear file 2 stand upright, so a hard material is appropriate. Also, the size of the first clear file 11 and the second clear file 12 can be an appropriate size depending on the intended use, such as A4 or B5.

[0025] As shown in Figure 7, the bottom portion 31 is foldable, allowing the foldable clear file 2 to be positioned to stand on its own, or to be stored by placing it between books or inside a bag.

[0026] If you want the foldable clear file 2 to stand on its own, you can spread out the bottom part 31 to make the foldable clear file 2 three-dimensional and allow it to stand on its own as shown in Figure 6.

[0027] Furthermore, if you want to store the foldable clear file 2 by placing it between books or inside a bag, you can fold the bottom part 31 to do so.

[0028] As described above, the foldable clear files 1 and 2 consist of a portion enclosed by the upper edges of the first clear file 11 and the second clear file 12, a portion enclosed by the lower edges of the first clear file 11 and the second clear file 12, and the centroid of the solid enclosed by the first clear file 11 and the second clear file 12. The centroid of this solid is projected onto a plane that includes the lower edges of the first clear file 11 and the second clear file 12, and that point must be inside the region enclosed by the lower edges of the first clear file 11 and the second clear file 12. Therefore, the shape of the foldable clear file of the present invention can be any shape as long as it satisfies this condition, and the design can be modified as appropriate without changing the essence of the invention. [Industrial applicability]

[0029] This invention is industrially useful because, by combining two clear files, it enhances stability when standing upright, and allows for easy transformation into a flat shape without removing any parts when the three-dimensional shape necessary for standing upright becomes inconvenient.
