[0004]

However, in the case of the conventional sheet-shaped automatic bookmark, since the whole is lightweight, for example, the automatic bookmark itself is displaced during reading and falls from the book. There was an inconvenience.

Further, as the remaining pages of the book gradually rise toward the end of the reading, the lightweight automatic bookmark also rises, and the bookmark part comes off the page currently being read, which is necessary as a bookmark. There was also a problem that the page pointing function could not be performed well.

Further, in the case of a conventional automatic bookmark, when the page that has been read is completely turned over, the bookmark part has a poor operability such that it interferes with the smooth operation of page turning, and durability is poor. There were also problems such as chipping.

In view of the above-mentioned problems of the prior art, the present invention is capable of automatically and stably indicating the page sheet currently being read without causing a positional shift or leaving the book until the end of reading the book. Not only that, the purpose is to provide an automatic bookmark that is excellent in operability and durability.

[0011]

FIG. 1 is an exploded perspective view showing an example of the present invention. The entire automatic bookmark 11 is made of, for example, a relatively thin plate-shaped metal material such as an iron material or a nickel material. It is configured by integrally combining the lower page sandwiching plate 12 and the upper page sandwiching plate 22, the magnet thin piece 20 made of a sheet-like rubber magnet, and the connecting piece 32 formed by, for example, integrally molding. ing.

Among these, the lower page sandwiching plate 12 is a lower sandwiching plate extending freely from the base end sloping portion 13 side to the back side of the page slip 2 of the book 1 shown in FIG. It has a portion 18 and is formed under a planar shape of a substantially rectangular shape such as a flat rectangle.

Further, the lower page sandwiching plate 12 is provided with a pair of bearing portions 14 and 14 which are erected in an upright direction via two opposing sides 13a and 13b located on the side of the base end sloping portion 13 thereof. The bearing portions 14 are formed with a shaft support hole 15 that is an elongated hole that is inclined forward and downward at an angle of approximately 45 degrees in the direction of the base end edge 13c of the base end grooved portion 13.

Further, the proximal-end squeezed portion 13 is formed with a slotted hole 17 having a long hole having a widthwise direction as a lengthwise direction in order to prevent slipping when a finger is brought into contact with this portion for operation. The non-slip portion 16 is formed.

Furthermore, the lower sandwiching portion 18 of the lower page sandwiching plate 12 is appropriately bonded to the upper surface 19 thereof with a magnet thin piece 20 made of, for example, a sheet-shaped rubber magnet using an adhesive. They are integrally fixed by using a fixing means, which enables magnetic attachment to the side of the upper sandwiching portion 26, which is a facing portion of the upper page sandwiching plate 22.
The side to which the magnet thin piece 20 is fixed, for example, the side of the lower page sandwiching plate 12 can be formed using a non-magnetic material.

As shown in FIG. 3A, the upper page sandwiching plate 22 is attached to the main page 1 from the side of the base end pressing portion 23 for the opening operation.
It is formed under a planar shape having a substantially rectangular shape such as a substantially rectangular shape having an upper sandwiching portion 27 that extends so as to freely contact the front side 3 of the page paper piece 2.

In this case, the upper page sandwiching plate 22 has a surface of the base end pressing portion 23 by interposing a standing piece 28 having a required height at the boundary position between the base end pressing portion 23 and the upper sandwiching portion 27. The height is higher than that of the upper sandwiching portion 26 by a required height.

The base end pressing portion 23 of the upper page sandwiching plate 22 is formed so as to be substantially parallel to the surface direction of the upper sandwiching portion 26 via the upright piece 28.

The base end pressing portion 23 is formed by a steep slope portion which is inclined upward from the standing piece portion 28 side and a gentle slope portion having a smaller front rise angle than the steep slope portion toward the end edge 23a. It can also be formed as a continuous surface. In this case, the steep slope portion of the base end pressing portion 23 is provided with an angle of about 20 degrees with respect to the surface direction of the horizontal upper sandwiching portion 26, and the gentle slope surface reaching the end edge 23a is similarly sandwiched by the upper sandwiching portion. It is desirable to form an angle of about 12 degrees with respect to the surface direction of the attachment portion 26.

Further, at a substantially central position of the base end pressing portion 23, there is formed a through hole 26 into which the male screw member 29 screwed with the female screw portion 36 of the connecting piece 32 can be inserted.

On the other hand, the connecting piece 32 is provided with the lower page sandwiching plate 12 and the upper and lower page sandwiching plates 22 under the condition that the lower sandwiching portion 18 and the upper sandwiching portion 27 can freely come into contact with and separate from each other. Are interleaved to integrate the two.

That is, the connecting piece 32 includes the proximal end gripping portion 13.
Main body portion 33 located between the base end pressing portion 23 and the base end pressing portion 23, a pair of support shaft portions 34, 35 protruding from the main body portion 33, and a female screw portion 36 formed at a substantially central position of the main body portion. And Fig. 3
As shown in (b), it is formed by a flexible bookmarker portion 38 which is arranged in the main body portion 33 so that the front side 3 of the page paper piece 2 of the book 1 can be pressed freely.

Of these, at least the main body portion 33 and the pair of support shaft portions 34, 35 can be integrally formed by resin molding. At that time, if the nut material 37 is also embedded, the female screw portion 36 is formed. Can also be formed at the same time.

In this case, the pair of support shaft portions 34, 35 are formed in a rod shape having a diameter (thinner) thinner than the wall thickness of the main body portion 33, and the shafts of the pair of bearing portions 14, 14 have. In order to easily support the support holes 15 and 15 afterwards, one length, that is, the length of the support shaft portion 34 located on the left side in the example of FIG. 1 is set to the support shaft portion 35 located on the right side. Is formed to be shorter than the length.

Further, the flexible bookmarker portion 38 is used to hold down the top margin portion 4 side of the front side 3 of the page piece 2 of the book 1 currently read as shown in FIG. 3 (b),
If the book 1 has a structure that opens to the left as in the illustrated example, the supporting arm portion 39 that projects in a substantially C-shape in the left direction is provided to form the whole. If the book has a right-opening structure (not shown), the supporting arm portion is formed by projecting to the right to correspond to this.

In this case, the flexible bookmarker portion 38 can be attached to the main body portion 33 by joining the flexible bookmarker portion 38 made of a thin plate-like flexible rubber material to the main body portion 33 as shown in the figure. Besides, it can be integrally formed with the main body portion 33 by resin molding.

Next, the operation and effect of the present invention will be described with reference to the illustrated example. Prior to this, first, the assembling procedure will be described. A pair of bearings 14, 14 having shaft supporting holes 15 at the same position on the lower page sandwich plate 12 are first described.
Is formed on the side of the proximal end sloping portion 13, so that a relatively long supporting shaft portion 35 provided on the right side of the connecting piece 32 is inserted into the right shaft supporting hole 15, and then a relatively short supporting shaft portion on the left side is formed. 34 is inserted into the shaft support hole 15 on the left side to support the connecting piece 32. In addition, the lower page sandwiching plate 12 is the upper surface 1 of the lower sandwiching portion 18.
The magnetic thin piece 20 is fixed to the magnet 9.

Thereafter, the pair of supporting shaft portions 34, 35 are provided on the side of the connecting piece 32 so that the through hole 26 of the base end pressing portion 23 of the upper page sandwiching plate 22 faces the female screw portion 36 of the connecting piece 32. After adjusting the position through the male screw member 29, the male screw member 29 is inserted into the female screw portion 36 from the through hole 26 and screwed.

In this way, the lower bookmarker 12 and the upper bookmarker 22 are integrated with each other via the connecting piece 32, whereby the automatic bookmark 11 is assembled.

FIG. 2 is a side view showing the movement of the automatic bookmark 11, and when not in use or attached to the page paper piece 2 of the book 1, the lower side of the lower page sandwiching plate 12 is interposed via the magnet thin piece 20. The side sandwiching portion 18 and the upper sandwiching portion 26 of the upper page sandwiching plate 22 are in close contact with each other as shown in FIG.

At this time, the base end pressing portion 23 of the upper and lower page sandwiching plates 22 is hooked by the pair of support shaft portions 34, 35 via the upper edges 15a of the shaft support holes 15 of the pair of bearing portions 14, 14. It will be pivotally supported in a stopped state.

Further, when the automatic bookmark 11 is attached to the predetermined page paper piece 2 of the book 1, the upper page is supported while the base end sled portion 13 of the lower page sandwich plate 12 is supported by the index finger. The base end pressing portion 23 of the sandwiching plate 22 is pushed down with the thumb. As a result, the pair of support shaft portions 34, 35 smoothly move downward along the inclination of each shaft support hole 15, and eventually the lower edge 1 thereof.
5b, the lower sandwiching portion 18 of the lower page sandwiching plate 12 and the upper sandwiching portion 26 of the upper page sandwiching plate 22 are in the open state as shown in FIG. 2 (b). Become. At this time, since the non-slip portion 16 is formed on the proximal end squeezing portion 13 of the lower page sandwiching plate 12, the lowering support operation by the index finger can be surely performed.

Moreover, the series of opening operations performed at this time are such that when the base end pressing portion 23 of the upper page sandwiching plate 22 is pushed down, a pair of supporting members are provided so as to escape obliquely downward in the shaft supporting hole 15. Since it is possible to follow the movement of the shaft portions 34, 35 well, it is possible to reliably prevent wear of the support shaft portions 34, 35 due to friction during the opening operation. In addition, the principle of leverage that forms the fulcrum 42 when the pair of support shaft portions 34, 35 contact the lower edge 15b of each shaft support hole 15 can be easily performed against the magnetic force of the magnet thin piece 20. You can also

The attachment of the automatic bookmark 11 to the book 1 is shown in FIG.
It is performed under the open state shown in (b). That is, for example, if the number of the page paper pieces 2 to be read this time is 50, the page paper pieces 2 from the initial page paper piece 2 to be read this time are placed on the back side of the page paper piece 2 from the side of the top margin part 4 to The lower sandwiching portion 18 of the side page sandwich plate 12 and the upper sandwiching portion 26 of the upper page sandwich plate 22 are arranged on the front side 3 thereof.

Thereafter, the pressing force applied to the base end pressing portion 23 of the upper page sandwiching plate 22 is released, so that the 50th sheet (or plural sheets in some cases) may be interposed. Under the state, the lower sandwiching portion 18 of the lower page sandwiching plate 12 and the upper sandwiching portion 26 of the upper page sandwiching plate 22 are brought into close contact with each other as shown in FIG. ), The automatic bookmark 11 is attached to the book 1 while ensuring a separation distance t which is about 15 mm apart from the outer edge 2a of the page piece 2 and the outermost edge 39a of the support arm 39 of the flexible bookmark section 38, for example. You can

After mounting the automatic bookmark 11 on the book 1 in this way, the flexible bookmarker portion 3 is returned from the mounting position to the front side 3 of the page piece 2 at the beginning of reading this time by 50 sheets.
As shown in FIG. 3 (b), the support arm 39 of No. 8 is pressed to finish the preparation.

After that, by pulling out the page paper pieces 2 that have been read in order from the side of the supporting arm portion 39, the supporting arm portion 39 can always be positioned on the front side 3 of the page paper piece 2 that is currently being read. Therefore, even if the user suddenly interrupts the reading or falls asleep during the reading, the page piece 2 currently being read can be immediately known when the reading is resumed.

Moreover, since the automatic bookmark 11 is given a certain amount of weight to itself and is securely attached to the book 1 under the magnetic force, the remaining page slips 2 of the book 1
Even if the number of pages is reduced, the page pointing function required as a bookmark can be stably exhibited.

Although the present invention has been described above based on the illustrated examples, the content of the present invention is not limited to this. For example, the shaft support hole 15 may be a circular hole if necessary, and the antiskid portion 2 may be replaced by the notch hole 17 and the contact portion of the index finger may be an uneven portion, or an appropriate antiskid material may be fixed. Can be formed.

Further, the magnet thin piece 20 has an upper page sandwiching plate 22.
It may be fixed to the upper sandwiching portion 26 of. In this case, the upper page sandwich plate 22 side can be formed using a non-magnetic material such as a synthetic resin plate, but at least the lower page sandwich plate 12 side needs to be formed using a magnetic material. is there.

Further, the shape of the support arm portion 39 in the flexible bookmarker portion 38 is not only a substantially C-shape as shown in the drawing, but also a substantially V-shape if it can be smoothly pressed. It can also be formed by giving an appropriate curved shape.

Furthermore, as the male screw material 29, a taper screw can be used instead of a bolt material. When a taper screw is used for the male screw member 29 as described above, the female screw portion 36 of the connecting piece 32 is also formed by providing a screw hole in the connecting piece 32 itself.

[0043]

As described above, according to the present invention, the lower side sandwiching portion of the lower side page sandwiching plate and the upper side sandwiching portion of the upper and lower side page sandwiching plates are provided on the page paper piece of the book through the magnet thin piece. It is possible to place the flexible bookmark part on the front side of the page piece that is being read at all times while stably attaching it under the condition that the , Even if you fall asleep while reading, you can immediately know the page piece you are reading when you resume reading.

Moreover, since the automatic bookmark itself is given a certain amount of weight and is securely attached to the book under the magnetic force, it is necessary as a bookmark even if the remaining pages of the book are reduced. It is possible to stably exert the page indication function.

When the book is removed from the book after being mounted, the lower end sandwiching portion of the lower page sandwiching plate and the upper sandwiching portion of the upper page sandwiching plate are pushed down by pushing down the base end pressing portion of the upper page sandwiching plate. It can be easily done by pulling them apart.

Particularly, when the shaft supporting hole is formed by a long hole inclined at an angle of about 45 degrees, when the base end pressing portion of the upper page sandwiching plate is pushed down, the shaft supporting hole is slanted in the shaft supporting hole. Since it is possible to follow the movement of the pair of support shafts well in order to escape downward, it is possible to reliably prevent wear of the support shafts due to friction during the bottle opening operation. Moreover, the lower sandwiching portion of the lower page sandwiching plate and the upper sandwiching portion of the upper page sandwiching plate can be easily opened by the principle of leverage.

Further, in the case where the bottom end pinching portion of the lower page sandwiching plate is provided with a non-slip portion for stopping the sliding of the fingers, the lowering support operation for the bottom end pinching portion by the forefinger during the opening operation is more reliable. Can be done.
