Description

[Detailed description of the invention] Industrial field of application The invention relates to forms such as notebooks, diaries, and memo pads.

Conventional configurations and their problems Conventional bellows type folding notebooks have been constructed with both front and back covers made of magnetized ferromagnetic material. For example, Japanese Utility Model Publication No. 56-31391. In this case, the magnetized covers are attracted to each other by magnetic force to maintain the bound state of the covers, but since the cover and the main body of the notebook are fixed by adhesive or other means, they cannot be replaced. It is impossible.
In addition, for single-stitched books, the binding margin on the back is adhesively fixed to the hinge of the cover, and cannot be replaced as described above.

Furthermore, as an example of removably fixing the form body and cover using magnetic force,
Publication No. 55-46539, etc. However, in both cases, a permanent magnet is provided at the hinge portion of the cover, and a magnetic material is provided at the base or edge of the paper piece to attract and fix it.

Therefore, these methods can be applied to books with backs where the covers are already connected via a hinge, or to books with spines, but cannot be applied to folding notebooks with separate covers. Moreover, an iron core or steel plate is provided on the back of the form body, and a magnetic layer or permanent magnet is provided on the inner surface of the hinge part of the back cover, and although it is removable, it has drawbacks such as the inability to attract and fix the displays together. It was hot.

Purpose of the invention This invention uses magnetic force to attract and fix the main body and cover of a notebook, memo pad, etc., and also allows the covers to be attracted and fixed to each other by magnetic force through a space without an attraction surface. By adopting a double suction structure, the present invention aims to provide a notebook or other form that allows the main body of the form to be freely replaced and at the same time allows sufficient suction between the covers.

Structure of the invention In order to achieve the above-mentioned purpose, the invention narrows down the suction surface that fixes the form body and cover to the necessary central part or peripheral part, which is a part of the outermost surface on both sides of the form body. This achieves adsorption and fixation of the facing covers to each other through the remaining outer surfaces. Therefore, the structure consists of a notebook, diary, or other form body, and a center made of an ultra-thin magnetic material such as steel foil on both sides of the form body and located at symmetrical positions on the outermost surface of the form body. The suction surface or at least three peripheral suction surfaces, and the peripheral space surface or central space surface as the remainder of each of the outer surfaces excluding these suction surfaces, are held from both sides of the form body so that different polarity comrades face each other. It consists of both front and back covers having a large number of belt-shaped ferromagnetic materials magnetized on the entire surface, and the form body attracts one cover facing each other from the central attraction surface or the peripheral attraction surface, and these form bodies This notebook or other form has a double suction structure in which the front and back covers are suctioned and fixed to each other through a peripheral space surface or a central space surface that does not have a suction surface.

Therefore, the outermost surfaces of the main body of a notebook or other form, on which ultra-thin magnetic material such as steel foil is applied in advance, are individually attracted to the cover by the magnetic force of each cover, thereby being combined with the cover. On this occasion,
The ultra-thin magnetic material acts as a yoke to concentrate the magnetic distribution on the cover, and by providing the other suction surface in the same shape and symmetrical position as the suction surface provided on one outer surface of the form body, it can be used as a suction surface. In the area where the ultra-thin magnetic material is present, the magnetic force of the cover does not reach the facing cover, and almost no adhesion force between the covers occurs. but,
In areas where there is no ultra-thin magnetic material, the magnetic force of one cover passes through the form body and reaches the other cover, creating a mutual adsorption effect. This adsorption effect between the covers is strong because the ferromagnetic material provided on the cover is in the form of a large number of strips with different polarities facing each other, each having an independent adsorption effect.

In this way, since the ultra-thin magnetic material provided on the form body was made to have the same shape and symmetrical position on both sides, the entire ferromagnetic material layer provided on the cover was divided, and one side attracted the form body and the other side has realized a double adsorption structure that adsorbs the covers to each other. Therefore, the cover is in the form of holding the main body of the form in between, and it can be fixed regardless of the type, such as a bellows type or a memo pad, and the cover may also be made of two covers, and the spine Even covers with different types can now be reliably attracted to each other by magnetic force.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. 1 is a form body like a Jiyabara type folding notebook, 1',
1'' indicates the outermost sheet on both sides of the main body. 2 is a peripheral suction surface, which is provided on the outermost surface of the outermost sheet of the form body. This peripheral suction surface 2 is made of an ultra-thin magnetic material. Made of steel foil, thickness approx.
The diameter is 30 to 120 μm, and the surface is laminated with paper. Note that the surface is not limited to paper, but may also be decorated with synthetic paper, vinyl chloride, etc. It was provided in a square shape along the periphery of the outermost surface, and the central space surface 3 was formed at the center. Reference numeral 4 denotes a cover made of a soft synthetic resin plate containing ferrite powder and magnetized and molded to the size of a notebook cover.The dotted line portion 5 shows a state in which many strips are magnetized over the entire surface. The magnet can be either an anisotropic magnet or an isotropic magnet, but in the case of an anisotropic magnet, the cover can be attracted to an external magnetic material, and the product itself, such as a notebook, can be temporarily attracted and held on an external wall. can be done. The magnetized dotted line portions 5 between the covers 4, 4 are set so that the opposite polarities face each other and attract each other.

FIG. 3 shows another embodiment, in which 6 and 7 are front and back covers, which are integrated by a hinge part 8.
Reference numeral 9 indicates a single-stitched form body, 10 indicates a central suction surface made of an extremely thin magnetic material provided symmetrically at the center of both outer surfaces of the account, and 11 indicates a peripheral space surface. Although the cover and the notebook are shown separated, the center suction surface 1
0 is attracted to the magnetized surface of the cover 7, and the cover 6,
The seven members are attracted and fixed to each other via the peripheral space surface 11. Although the central suction surface 10 is shown as having a rectangular shape, it may have a modified shape such as a round shape or a diamond shape. In short, it is sufficient to have an adsorption force that can attract and hold the form body to the cover, and in the peripheral space surface, the covers can be attracted to each other through the form main body and the covers can be maintained in a bound state. According to this embodiment, even if you hold one cover and drop the other, or if you accidentally drop your notebook, the weight of the cover will cause it to fall off the notebook.
The weight of the cover will not damage the book.

FIG. 4 shows yet another embodiment, 1
2 and 13 are the covers that are integrated at the hinge, 14 is a memo pad made of many stacked sheets, and 15 is the peripheral suction surface made of ultra-thin magnetic material provided on the surface of the outermost memo pad, which is approximately U-shaped. There is. Due to the magnetized surfaces of the covers 12 and 13, the outermost peripheral adsorption surfaces 15 of both memo pads 14
is fixed by suction, and the memo pad in the middle part is clamped and held integrally as the front and back covers 12 and 13 are suctioned and fixed. 16 indicates the central spatial plane.

In any of the above embodiments, the form body is adsorbed and fixed to the cover, so it can be easily separated, the cover remains the same, and only the form body can be freely replaced. The body is extremely thin, like steel foil, and does not pose any obstacles or add weight.

Effects of the invention As described above, the present invention provides a central suction surface or a peripheral suction surface in the same shape and symmetrical position on both outermost surfaces of the form body, and makes the part without these suction surfaces the peripheral space surface or the central space surface. Therefore, as a notebook or memo pad, it has a double suction structure in which the covers adhere to each other, and at the same time, the outermost surface of the form body is suctioned to each cover. Therefore, the facing front and back covers may be two independent covers, or may be integrated with a hinge in the center. The main body of the form may also be a bellows-type folding notebook, a single-stitched notebook, or a memo pad with multiple sheets stacked on top of each other. The symmetrical peripheral suction surface or central suction surface formed on the outermost surface of both of the form bodies uses steel foil as an ultra-thin magnetic material, making it thin and convenient to carry. The magnetic force allows the main body of a notebook, memo pad, etc. to be reliably attracted and held. Furthermore, since it only has a suction surface, it can be easily separated and replaced, which has a great practical effect.
