Description

The present invention has a page holding function with a simple mechanism that can be manufactured with a general-purpose material used for a general clear file, etc., and can easily turn pages, and a book cover can be easily attached and detached. It relates to a reading aid consisting of a lectern having a ball joint, a rotating hinge, a flexible arm and a fixing clamp, which is a connection that can be and is firmly fixed.

In the book covers, book holders, and lecterns that have been applied for so far, there are various points in which the mechanism for realizing the page retention function has been devised.

Patent Document 1 states that the desire to "read one page or several lines before falling asleep" is to be fulfilled, so a transparent sheet is attached to the book cover, and the left and right pages are covered separately, and the back. A book cover that holds down the page by fixing it with a magnet (at the bottom of the book cover table) is disclosed.

In Patent Document 2, a book having a simple mechanism in which a wire is provided inside a page holder provided in a strip shape on the back surface of the book so as to protrude from the size of the book, and the portion protruding from the book is bent to form a page holder. The holder is disclosed.

In Patent Document 3, the cover of a book is sandwiched between spring-loaded clips at both ends, the page presser body is expanded and contracted to fix the book in an open state, and the left and right ends of a spread page other than the cover are further provided at both ends. Is disclosed as a book holder with a precise mechanism of holding a page by sandwiching it between a slightly larger arch-shaped binder clip equipped with a detent rubber.

Then, in Patent Document 4, attention was paid to the fact that the page retainer is a transparent plate, but a groove is provided in the center of the lectern in the vertical direction and in the portion where the spine of the book hits, and a rectangular cross section having an inclination in the same direction is provided. As a prior art, a lectern having a page holding function of making holes with magnets on the left and right, inserting a metal rod with a transparent plate into the holes, and holding the page using magnetic force is disclosed.

As the purpose of the book cover of Patent Document 1, the emphasis is on protecting and retaining pages, so it is troublesome to turn pages one after another.

Patent Document 2 seems to have a problem in durability against repeated bending and stretching of a wire, which will be bent over and over again to hold a page. In addition, the wire hides the letters, making it difficult to read.

The reading support device of Patent Document 3 has a complicated structure and is likely to be expensive, which raises the question of how realistic it is. Also, there is a question as to whether the page presser works well near the beginning and end of reading.

Patent Document 4 describes a "rectangular shape made of plastic, metal plate, etc." having a rectangular cross section having a slope in the vertical direction, a concave groove in the vertical direction, and a slide stopper for fixing the top and bottom of the book on the back thereof. The lectern with a magnet-filled hole at the tip of the "flat lectern" for pointing a metal rod with a transparent page holder is A5, with one hole on each side that matches the size of the book. In order to correspond to the size, it is larger than A4 size. It seems too costly and impractical to attach a rail to slide the base plate of a book to this stand.

In addition, the reading aids for assistance on the market are large-scale and expensive, and there is no cheap and simple reading aid.

The present invention is a book cover which is an inexpensive material, can hold pages by a simple mechanism, and can easily turn pages.
It is an object of the present invention to provide a reading aid consisting of a lectern made of general-purpose members, which can be easily attached and detached, can be released, and can be read even in a lying position.

In order to solve the above purpose, make a book cover with the same material as the cover of a general clear file, and make a transparent claw with the material of a PET bottle.

As the invention according to claim 1, the book cover is provided with a page holding member for holding the left and right pages, and the page holding member is placed in the center of the book from the left and right outer portions of the book attached to the book cover. has a claw of the extending out transparent toward the transparent nail, the pages under the transparent nail have a resilient force to allow pulling out with presses elastically, to the left and right of the book cover, than transparent nails A reading aid is provided characterized in that a book cover tongue having a high elastic coefficient is formed and a transparent claw is attached under the tongue of the book cover .

As an invention according to claim 2 , the book cover according to claim 1 is provided with a lectern to be detachably attached, and a ball joint and a rotary hinge for freely changing the orientation of the lectern are provided on the lectern. Attached, a flexible arm is attached to the rotating hinge to freely change the posture of the lectern.
A reading aid is provided characterized in that the tip of the flexible arm is provided with a fixing clamp for fixing the lectern to a stable object such as a desk or bed near the reader.

As an invention according to claim 3 , the lectern according to claim 2 is provided with a universal support leg for receiving the weight of the lectern and a book attached to the lectern and supporting the stable object. Characteristic reading aids are provided.

As the invention according to claim 4 , a tongue-shaped insertion portion for detachably attaching the book cover according to claim 1 is provided in the vertical direction of the book in the center of the reading table according to claim 2 or 3. A reading aid is provided in the center of the book cover, characterized in that an insertion guide into which a tongue-shaped insertion portion is inserted is provided along the vertical direction of the book.

It is characterized in that a removable sandwiching bar that holds the book cover by sandwiching the front cover and a removable sandwiching bar that sandwiches and holds the back cover of the book cover in the inserted state are detachably provided. Reading aids are provided.

As the invention according to claim 6 , the book cover according to claim 1 is inserted and fixed into the tongue-shaped insertion portion of claim 4 of the lectern according to any one of claims 2 to 5. When this is done, a reading aid is provided, characterized in that a plug-in cover straightening bar is provided on the back side of the lectern to correct the bending habit of the back of the book cover in the relevant portion.

According to claim 1, since the page holding of the book cover is a transparent claw, even if the transparent claw is extended to the center side of the book to enhance the page holding function, the characters on the page are not obstructed and the book is read properly. it can.
Since the transparent claws extending toward the center of the book have elasticity, the pages do not turn unexpectedly, and the reader's finger can turn the pages appropriately one by one.
Further, since the elastic modulus of the book cover tongues formed on the left and right sides of the book cover is higher than that of the transparent claws, the stiffness of the root side of the cantilever type page holding member composed of the transparent claws and the tongue becomes stronger .
By strengthening the stiffness on the root side, the page retention of the book becomes closer to the open state .
Due to the function of the tongue, the transparent claws make it easy to turn pages, and the pages do not turn unexpectedly, so that the reader can read comfortably and the book can be folded .

The page holding mechanism of the present invention holds the page by the resultant force of the reaction force of the transparent claw and the reaction force of the tongue and the frictional force of the transparent claw against the force to turn the page, instead of using a wire or the like. Because it does, the wires do not hide the characters and interfere with reading at all, and the reader can turn the pages with just his finger and read comfortably without touching the book. I can read. Once you get used to it, the reader can turn pages with just one finger.

According to claim 2 , the orientation of the lectern can be changed by the ball joint and the rotary hinge of the lectern to which the book cover is detachably attached, and the posture of the lectern can be changed by the flexible arm. Therefore, the reader can read properly even when he / she is lying down, for example.

According to claim 3 , since the weight of the lectern and the book mounted on the lectern can be supported by the universal support legs provided on the lectern, the load load applied to the ball joint, the rotary hinge, and the flexible arm is reduced. The orientation and posture of the lectern can be stably maintained.
In addition, by providing the free support legs, the shaking of the lectern that occurs when turning pages is eliminated.

According to claim 4 , by inserting the tongue-shaped insertion portion of the lectern into the insertion guide of the book cover, the position of the book cover with respect to the lectern is determined, and the book cover is firmly attached to the lectern. ..

According to claim 5 , the front and back covers of the book can be held firmly by sandwiching them with removable sandwiching bars and holding them on the lectern. Therefore, a transparent claw reinforcement part is attached to change the orientation of the book. Even if the book is tilted 90 degrees, the book can be properly held and the pages can be turned and read without rattling without falling from the lectern.
If the thickness of the paperback book / new book is about 20 mm, you can attach transparent claw reinforcement parts to the left and right to hold the page properly and read by turning the page with your finger, even if you are reading on your back. Can be done.

According to claim 6 , the book cover is completely opened by the insertion part cover correction bar provided on the back surface of the tongue-shaped insertion part of the lectern, so that the book itself approaches the open state. Makes it easier to read.

The book cover 2 of claim 1 of the book cover and the lectern constituting the reading assist device according to the first aspect of the present invention will be described.
The material of the book cover 2 is a polypropylene plate with a thickness of 1 mm (the same material as the cover of a general clear file, etc.), and the transparent claw 3 is a polyethylene terephthalate transparent plate with a thickness of 0.5 mm (the same material as the material of a PET bottle). use.

The pages of the book are patented because they are a simple mechanism that is held by the frictional force of the transparent claws 3 made of the above transparent plate, the reaction force of the tongue formed on the book cover, and the reaction force of the transparent claws 3. Unlike Documents 3 and 4, it is not costly, and unlike Patent Document 2, it does not use any wire or the like, so that it does not hide characters and make it difficult to read.
Even if the transparent claw 3 is extended to the center side of the book or the thickness is increased to enhance the page holding function, the characters on the page are not obstructed and the book can be read appropriately.
Further, since the transparent claws extending toward the center of the book have elasticity, the pages do not turn unexpectedly, and the pages can be turned appropriately one by one by the reader's finger. Patent Document 1 It doesn't take much time to turn pages like this.
However, if it is extended or thickened, it becomes difficult to turn the page and the comfort is reduced.

FIG. 1 is a bird's-eye view in which the book cover 2 is placed on the palm of the hand for reading. The page is held by the transparent claw 3 while it is placed on the palm of the hand, and the page does not turn unexpectedly.

When turning the pages of a book, use your finger to lightly press the page vertically, pull it out from under the transparent claw 3 on the left side, and insert it under the transparent claw 3 on the right side in the same way. You can easily turn pages and read with just your finger.

FIG. 2 is a developed view of the book cover 2. Weld the insertion guide 8 of the same material as the book cover to the inside of the back cover of the cover in advance, and insert the book cover notch 6 into which the transparent claw 3 is inserted into the cover pocket 5 to make the book cover tongue 7. deep.
FIG. 3 is a detailed view of the part where the transparent claw 3 is attached to the cover pocket 5. The transparent claw 3 is inserted into the trapezoidal notch 6 of the book cover from the outside to the inside of the pocket. Join with welding of the cover pocket 5.

The reason why the notch 6 was made into a trapezoidal shape was that it was initially cut into a U shape, but as it was actually used, the cut progressed and the stiffness of the base of the transparent claw 3 became weaker. Therefore, in order to disperse the direction of force and make it difficult for the cut to proceed, we changed to a trapezoidal cut. Koshi is also stronger than before.

The shape of the cover pocket 5 is also easy to store books even when attached to the lectern 13, and the entire pocket can be evenly sandwiched when sandwiched by the sandwiching bar. The shape is only rounded corners, such as 3.
Further, the cover pocket welded portion folded-back 4 shown in FIG. 2 is provided to be folded back and welded as shown in FIG. 4 so that the finish of the left and right end welded portions of the book cover 2 is not left uncut.

FIG. 4 is a front view and a cross-sectional view of the completed book cover.
Overlapping part of transparent claw 3 and book cover tongue 7 with different elastic modulus so that the cut of the tongue does not proceed due to movements such as when putting on and taking off the book or when folding while holding the page (The shaded areas shown in FIGS. 3 and 4) are not joined.

Further, as shown in FIG. 5, the book cover 2 is provided with a margin of 25 mm on both the left and right sides so that the book cover 2 can be folded while holding the page with the transparent claws 3. Therefore, no bookmark is required.

The book cover 2 comes in three types: S size for both paperback books and new book editions, M size for both B6 and 46 sizes, and L size for both books and A5 sizes. The back dimensions are 15 mm for S size and M size. 20 mm and L size 25 mm as standard.

The durability of the cover is increased by providing two folds on the back, one at the standard dimension and one at plus 5 mm on each side.
In addition, each size can handle books up to a thickness of about 10 mm (the left and right plus 5 mm can be absorbed within a margin of 25 mm), but it is difficult to fold while holding the page.

FIG. 5-The size-specific dimensions of the total width W and total height H of the book cover in the dimensional drawing in the folded state are shown below.
For the total width and height, use the larger size of the book that can be used for both purposes.
S size Overall width W = 105 + 25 = 130 mm, Overall height H = 182 + 3 = 185 mm
M size Overall width W = 128 + 25 = 153 mm, Overall height H = 188 + 3 = 191 mm
L size Overall width W = 150 + 25 = 175 mm, Overall height H = 220 + 3 = 223 mm
And.

Next, the lectern 13 of claims 2 to 6 constituting the first embodiment will be described.
As shown in FIG. 6, the lectern 13 is provided with a ball joint 12 and a rotary hinge 11 for freely changing its orientation, and the lectern 11 is for freely changing the posture of the lectern. The flexible arm 10 is attached, and a fixing clamp 9 for attaching the lectern to a stable object such as a desk or a bed near the reader is provided at the tip of the flexible arm 10.

The lectern 13 is fixed to a stable object in the vicinity by a fixing clamp 9, and the insertion guide 8 provided on the book cover 2 is inserted into the tongue-shaped insertion portion 14 provided on the lectern 13 shown in FIG. By inserting it into, the book cover 2 is securely attached.
At this time, since the tongue-shaped insertion portion 14 is made by cutting out the lectern 13, the insertion shown in FIG. 6 is shown in order to correct the bending habit of the back portion of the book cover 2 which corresponds to the cut-out portion. The part cover correction bar 15 is installed on the back side of the lectern 13. As a result, the book cover is completely open, and the book itself is close to the open state, which makes it easier to read.

Further, when the book to be read is a book or A5 size, the total weight of the book and the lectern 13 cannot be supported by the flexible arm alone, so that the insertion portion cover correction bar 15 is used as shown in FIG. , The free support leg 18 installed with the truss screw and the wing nut is lowered, the direction is adjusted, tightened, and the weight is shared.
As a result, the orientation and posture of the lectern 13 can be stably maintained.

If you want to read the book in the same orientation as the top and bottom, the fixing up to this point is sufficient, and the reader can read the book with the flexible arm 10 and rotary hinge 11 of the lectern 13, the ball joint 12, and the free support leg 18. And without having a book cover 2, it has a page holding function, and you can turn pages and continue reading with just the reader's finger, so you can read without letting go, without numbness or tiredness of your arms. You can sit in a chair, lie down, and enjoy reading in any position you like.
And the merit of fixing up to this point is that it is easy to put on and take off the book together with the book cover 2, so the book that was read by attaching it to the lectern 13 last night is pulled out together with the book cover the next morning, and commuting to work or school. It is easy to carry it with you on the go, read the rest, and attach it to the lectern again after returning home.

Next, strong fixing of the book cover 2 to the lectern 13 using the removable sandwiching bar 16 will be described.
Detachable sandwiching bars 16 shown in FIGS. 6, 7 and 8 are provided at the left and right ends of the lectern 13. With this removable sandwiching bar 16, the book with the book cover 2 attached is sandwiched together with the book cover, and the upper and lower parts of the bar are tightened and fixed with the truss screws and wingnuts attached to the lectern 13 (strong fixing). By attaching the transparent claw reinforcement part 17 and tilting the book 90 degrees as shown in FIG. 10, the page can be held and the page can be turned and read with only the reader's finger. Therefore, it is ideal for reading while lying down. Further, since the transparent claw reinforcing part 17 is made of the same material as the transparent claw 3, the characters are not hidden and difficult to read.

Also, if it is a book with a thickness of up to about 20 mm or a new book version, it can be held only by the flexible arm, so the free support legs 18 can be folded up and stored, and the transparent claw reinforcement parts 17 are placed on the left and right ends of the book cover 2. By attaching it, the reading surface can be turned downward, the page can be held even in the supine position, and the reader can turn the page with the finger to read.

When strongly fixing using the removable sandwiching bar 16, as shown in FIG. 9a, the upper part is provided with a vertical loose hole, and the lower part is provided with a play, as shown in FIG. 9b, depending on the thickness of the cover of the book. An L-shaped notch is provided so that it can be sandwiched, and it is tightened with a truss screw and a wing nut that are attached through a loose hole of the lectern 13.

The procedure for pinching is to first loosen both the upper and lower screws, remove the lower part of the removable pinching bar, pinch the book together with the book cover 2, and then make the L-shaped notch at the bottom of the bar and the truss screw that penetrates the lectern. Tighten the lectern and bar while pinching them from the front and back with the wing nut, and then tighten the upper truss screw and wing nut to ensure tightening.

Since the truss screw has a large outer diameter of the head and a large ground contact area, when tightening, lightly press the screw head from above with your fingers and tighten the wing nut to obtain the tightening required for pinching, so use a screwdriver. No tightening is required. The same applies when loosening.
The upper and lower truss screws and wingnuts of the removable sandwiching bar 16 are processed so that they will not come off even if they are loosened, in order to prevent them from being lost.

In FIG. 10, the book cover 2 and the reading aid by the book cover 13 of the present invention are attached to the book cover 2 and attached to the headboard of the bed by the fixing clamp 9 of the book cover 13, and the book cover 2 is attached. After sandwiching the book with the removable sandwiching bar 16 and firmly fixing it, lower the free support leg 18 to adjust and fix the orientation, attach the transparent claw reinforcement part 17, tilt the book 90 degrees, and lie down on the bed. It is a diagram of the first embodiment of the present invention in which the reader is reading without letting go.

As a second embodiment of the present invention, a mode in which the book cover 2 of claim 1 is used alone will be described.
The book cover 2 of the present invention itself has a page holding function, and the reader can easily turn the page and continue reading with only the reader's finger. Therefore, the reader can read the book except when reading in a standing position. There is no need to hold the cover 2 in your hand. Therefore, in addition to ordinary reading (sitting), when reading a book or at work, when reading a book, copying it into a notebook while looking at a book, typing in a computer, etc., it can be used by placing it on a desk. Expected to play an active role in applications.

Also, when reading in a standing position, the reader puts the book cover 2 on the palm of one hand and uses the fingers of the other hand only when turning the page, so he holds onto the strap when commuting to work or school. You can also read comfortably.
However, the material of the book cover 2 of the present invention is very slippery, so when reading in a standing position, put a non-slip sticker on the front side of the book cover 2, or hang a string or rubber string on it. It is necessary to take measures to prevent slipping, such as making clues. (When commercializing it alone, consider right-handed and left-handed people, and make a slit-shaped notch in the cover so that you can insert and hold the four fingers from the index finger to the little finger so that you can hold the cover securely. Take measures and commercialize.)

The reading aid of the present invention is very useful for those who have to lie down in the hospital or at home, which triggered the invention of this device.
Even if you are a healthy person, you need to hold a book in your hand if you have this reading aid when you lie down on the bed or sit in a chair and read a book for a short time before bedtime or on holidays. I am confident that I will be very pleased because my arms will not get tired.

Further, as shown in the second embodiment, the book cover 2 of the reading aid of the present invention is expected to be in demand as a single book cover.
The polypropylene plate material used for the book cover 2 this time has various colors and transparency, and since it is possible to print a pattern or a pattern, it is possible to produce a wide variety of products.
Also, if you cover the book cover 2 with leather while leaving the inside of the front and back cover pockets, you can create a high-class book cover while retaining the functions of the book cover of the present invention, or cover it with a cotton cloth. , Casual book covers of various designs and colors can be produced.

Further, the subject of the present invention is three sizes of reading materials: S size for paperback books / new book editions, M size for B6 size, and L size for books. If demand can be expected, books larger than this or Book covers for magazines can also be handled by changing the thickness of the material or the material itself.
In addition, although the cost of the lectern is high, it can be used with a flexible arm for heavy loads or a tripod type, so it can be used with a large size.
