Magnetic covered folio case

A magnetic covered folio case is formed of a pair of magnetizable sheet members forming the covers with oppositely polarized areas on these cover members, so that they will be attracted one to the other when in facing proximity. Arranged between the cover members are a plurality of hingedly attached folio sheets in an accordian folded configuration, with each end folio sheet secured to a cover. Separating the cover members extends the accordian folded folio sheets, exposing the faces of the folio sheets, which may be formed to accommodate writing. There may be secured to the faces of the accordian folded folio sheets one or more pocket forming members to retain articles on said sheets. Sheet and cover member shape may be rectangular, triangular, circular, or of a variety of polygonal shapes. A flap of magnetizable sheet material is hingedly secured to the edge of one cover member to overlie at least a part of the other cover member, and decorative or identifying magnetic sheet elements are provided for selective securement to one or the other of the cover members to appropriately decorate or mark same. A key ring attachment may if desired be attached to one of the covers, and/or a scale rule may be formed on the folio sheets.

BACKGROUND OF THE INVENTION 
This invention relates to the art of folio cases, that is cases holding a 
plurality of attached sheet members to form either a memo book or diary, 
stamp or photography album, or the like. 
Such folio cases have long been formed employing a pair of cover members, 
ranging in rigidity from the fairly flexible to the stiff and unbendable. 
Between these cover members, the folio sheets to be contained are secured. 
In forming folio cases, particularly those which are subject to being 
moved about, consideration is given to insuring the fact that the cover 
members will maintain their position relative to the closed folio sheets 
to protect and retain them in desired position, while at the same time 
providing ready access to these sheets when desired. Further, it is often 
desired to provide means for marking or decorating the cover of the case. 
Additionally, it is often desired to support sheet articles such as stamps 
or pictures in the folio with both surfaces of the sheet article protected 
and/or to retain keys in association therewith and/or to provide means for 
measuring. 
BRIEF DESCRIPTION OF INVENTION 
It is with the above considerations in mind that the present improved folio 
case has been evolved, serving to provide secure retention and protection 
for the folio sheets, while at the same time permitting easy access to the 
sheets when desired, permitting supporting of a sheet article on the folio 
sheet, and providing selectively changeable decorative or identifying 
indicia on the case cover, along with key retaining means and/or measuring 
means. 
It is accordingly among the primary objects of the invention to provide an 
improved folio case serving to securely retain and protect folio pages 
within the case, while permitting ready access thereto when desired. 
Another object of the invention is to provide an improved folio case which, 
facilitates retention of keys. 
It is also an object of the invention to provide a folio case serving to 
retain a scale rule. 
A further object of the invention is to provide an improved folio case to 
which desired decorative or identifying indicia may be selectively 
applied. 
An additional object of the invention is to provide a folio case which may 
support sheet articles, such as stamps or pictures with both surfaces of 
said sheet articles covered. 
These and other objects of the invention which will become hereafter 
apparent are achieved by forming a folio case with magnetizable covers 
formed of a sheet material, such that areas of opposed covers will be 
oppositely polarized, so that the covers when brought into facing 
proximity will be attracted one to the other. A plurality of hingedly 
attached folio sheets are arranged and secured between said cover members 
in an accordian folded configuration, and pocket forming elements may, if 
desired, be secured to said folio sheets. A flap of magnetizable sheet 
material is hinged to one cover to permit it to overlie at least a part of 
the other cover when the covers are brought together to further insure 
case closure. Magnetized elements may be selectively applied to the covers 
to provide a desired decoration or identifying indicia on said covers. A 
key attaching element may if desired be formed on one of the magnetizable 
covers, and if desired slots may be formed extending across the folio 
sheets with the indicia of a scale rule arranged adjacent the slots.

DESCRIPTION OF PREFERRED EMBODIMENT 
Referring now more particularly to the drawings, where like numerals in the 
various FIGS. will be employed to designate like parts, as best seen in 
FIG. 1, a folio case 10 embodying the invention is illustratively shown as 
formed with a pair of spaced magnetizable cover members 15, and 16, as 
shown one on the extreme left, and the other, to the extreme right of FIG. 
1. The magnetizable cover members 15 and 16 are preferably formed of a 
magnetizable sheet material, as described below, with oppositely polarized 
areas, so that the covers will be drawn towards each other when in facing 
proximity. 
A flap 17 similarly formed of a magnetic sheet material having areas of 
opposite polarity to the cover opposed to the one to which it is hinged is 
secured to the free edge of one of the flaps, as best seen in FIGS. 1 and 
2. 
A tab 18 having an aperture 19 may be formed on one of the cover members, 
16 as seen in FIG. 1, to permit attachment to a key chain or ring. 
If desired as shown in FIG. 3, a scale rule may be provided by forming 
slots 21, with indicia corresponding to a scale rule along the slot edges. 
Secured between one edge of cover member 15 and cover member 16 are a 
plurality of hingedly attached folio sheets 25, which, as seen in FIG. 1, 
are arranged in an edge to edge relationship to form an accordian folded 
configuration. These folio sheets, as best seen in FIG. 3, though 
geometrically similar in shape to that of the covers, are preferably 
slightly smaller. 
According to the invention, the folio sheets may be provided as desired 
with pocket forming elements which may be selected of different types. 
Thus, to the left in FIG. 1, a pocket forming element 31 is illustratively 
shown formed of a sheet of transparent material only one edge 32 of which 
is adhered to the folio sheet 25 in connection with which it is 
positioned. Another form of pocket forming elements 34, as seen to the 
right in FIG. 1, is similarly formed of a sheet material, preferably 
transparent, and secured to folio sheet 25 along three edges 35, 36 and 37 
of the pocket 34, leaving one side open between the pocket forming element 
34 and the folio sheet 25. 
As best seen in FIG. 2, one or more selectively applicable and removable 
decorative and/or identifying elements (three being here illustratively 
shown) 40, 41, and 42, formed of a magnetic sheet material, are provided 
for securement to the exterior surfaces of one or both covers 15 and 16 of 
the folio case. 
In the embodiment illustrated in FIG. 4, the folio sheets 45 are shown as 
formed of a triangular configuration. Cover elements 46 and 47 are 
illustratively shown as geometrically similar to the folio sheets of a 
triangular configuration slightly larger than that of the folio sheets 45, 
to be encased therebetween. As in the embodiment of FIGS. 1-3, cover 
members 46 and 47 are made of magnetic sheet material magnetized with 
areas of opposed polarity with respect to each other so as to facilitate 
drawing of one cover relative to the other when they are brought into 
facing proximity. 
In the embodiment of the invention illustrated in FIG. 5, the cover members 
56, 57 and the folio sheets 58 are formed of a circular configuration, 
with the cover members 56 and 57 being slightly larger in diameter than 
that of the folio sheets 58. As in connection with the cover members 15 
and 16 of the FIG. 1-3 embodiment, cover members 56 and 57 are formed of a 
magnetizable sheet material having oppositely polarized areas drawing one 
cover member toward the other when they are brought into facing proximity. 
The folio sheets may be made of any of a variety of conventional sheet 
materials, such as paper or sheet plastic. The cover members are made of a 
magnetizable sheet material, which may be formed in accordance with the 
invention, preferably by impregnating sheet plastics such a vinyl or 
polyvinyl with ferromagnetic particles. Alinico powder and/or iron filings 
embedded in the plastic during formation of the plastic has been found to 
produce eminently satisfactory magnetizable qualities in the sheet 
material. Alternatively, the sheet material may be formed by a laminate of 
plastic or paper sheeting surrounding a central foil of ferromagnetic 
materials, such as sheet steel or the like. 
Where the folio is to be employed for holding stamps, photographs or the 
like items, commonly held so that they are subject to ready visual 
inspection and subsequent removal, it is preferred to form the folio 
sheets of a sheet plastic material such as sheet vinyl, and provide a 
pocket forming element such as element 31, which comprises a flap of 
transparent sheet material of a similar plastic. It is found that the 
conventionally calendered smooth surfaces of these sheet plastics provide 
a relative surface adhesion therebetween, so that when the pocket forming 
element is lifted and a picture or stamp is inserted between the pocket 
forming element and the folio sheet, the element 31 will provide a 
protective overlying flap or pocket for the picture or stamp. 
Alternatively, the pocket forming element may be sealed along three sides 
as in element 34 shown in FIG. 1. 
In forming the above described folio case, the folio sheets are preferably 
cut as a single element from a length of sheet stock, and provided with 
fold lines between the areas desired to form the folio sheets. 
In the embodiment illustrated in FIGS. 1-3, this may be accomplished by 
continuously cutting and scoring the desired strip of folio sheets from a 
large sheet of stock sheet material, utilizing a conventionally available 
cutting and scoring roll so as to simultaneously cut the strip of folio 
sheets and score the desired fold lines along which hinging is to take 
place to provide the desired accodian folded group of folio sheets 25, 
which is illustrated in FIGS. 1-3. 
Where a triangular or circular configuration is desired for the folio 
sheets, this may similarly be accomplished by cutting and scoring a 
continuous sheet to form a strip of accordian folded folio sheets, as 
shown in FIGS. 4 and 5. 
After the cut and scored sheets forming the folio sheets are formed, cover 
elements of desired shape are secured thereto formed of the above 
described magnetic material. 
OPERATION 
As will be apparent to those skilled in the art, after forming the desired 
folio case as above described, the case may be utilized for any of the 
myriad purposes for which folio cases have conventionally been employed. 
Thus, where it is desired to employ the folio case for memorandum or diary 
entry purposes, the requisite number of sheets are provided formed of 
sheet material such as paper, on which written entries may readily be 
inscribed. 
Where the case is intended for use as an album for photographs, coins or 
stamps, it is preferred to make the folio sheets of a plastic sheet 
material, and provide same with desired pocket forming elements, which are 
preferably transparent. 
In use, as is apparent, when the covers are brought together, the 
oppositely polarized areas on these covers are brought together, one to 
the other, sandwiching the accordian folded sheets therebetween to provide 
a compact, secure package, as seen in FIG. 1, in which the sheets are held 
flat, with any items positioned thereon maintained securely. Flap 17 when 
folded over from one cover to the other provides further security. 
When it is desired to expose the folio sheets, the application of 
sufficient manual force to the covers to separate them to overcome their 
magnetic attraction brings them apart, serving to permit the folio to be 
opened to the position shown in FIGS. 3, 4 or 5. 
The above disclosure has been given by way of illustration and elucidation 
and not by way of limitation, and it is desired to protect all embodiments 
of the herein disclosed inventive concept within the scope of the appended 
claims.
