Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The idea is that when reading a book on a reading stand, specifically in a supine or sitting position, there is no step in the spread of the upper bound book, regardless of the number of pages to be read, and the left and right pages are close to the same plane. Therefore, it relates to a lectern that does not burden the visual sense.

[0002]

[Prior art]

 Traditionally, when reading top-bound books, lie down on your back, lie down, hold the book in your hand, sometimes put the top-bound book on your chest, touch one end of the cover on the floor and It is usual to hold the edge of the cover with your hand and turn the page with the other hand if necessary. This is enough for a short time, but it is very burdensome for a long time, and it is not long lasting because it is painful. This is even more painful, especially since you have to go out in the cold winter months. In view of the above, various prior arts have been proposed for a reading stand that allows easy reading regardless of the season without putting a burden on the body even in a supine state.

[0003] These prior art reading stands are basically composed of a book holder and a support for supporting the book holder. As the support, there is a supporter capable of holding a TV set (Japanese Patent Laid-Open No. 8-164171) and a supporter provided with a book stand (Japanese Patent Laid-Open No. 7-5434). In addition, a vertical support cylinder is erected on a bed, a horizontal support cylinder is horizontally installed integrally with the bed, and a book holder is rotatably held at a tip end thereof (Japanese Utility Model Laid-Open No. 6-81331). ). In addition, one using an L-shaped curved pole as a support (JP-A-11-332657) and one using a flexible support member (flexible bellows bar piece) (JP-A-8-164170) and so on.

[0004] In the book holding device supported by these supports, the surfaces for holding the front and back covers of the book and the back surface in contact with each other are formed flat. For example, the back plate of a book-mounting stand protruding a top plate and a base plate (Japanese Patent Laid-Open No. Hei 11-332657), a reading table 1 with a shelf 7 provided below it (Japanese Utility Model Laid-Open No. 6-38674), In addition, a rectangular back plate 2 having a top plate 3 and a bottom plate 4 protruding forward (Japanese Patent Laid-Open No. 11-196942) is also added. are doing.

[0005] In top binding, the number of left and right pages differs greatly between the beginning and end of reading. If the front cover (Table 1), the spine and the back cover (Table 4) are held in close contact with a flat plate, there will be a level difference in spread. The thinner page is concave, and the thicker one is convex. Therefore, the left and right pages are out of balance, and it is difficult to keep them. Therefore, in order to ensure reliable holding, a groove 2 is provided in a portion where the back rests, and support tables 3 and 4 in Tables 1 and 4 are additionally provided so that the left and right pages have the same visual perception. No. 1 and Table 4 form an obtuse angle (Japanese Utility Model Laid-Open No. 7-24138).

[0006] In this prior art, as is clear from the comparison in the figure, the left and right pages have the same vision near the middle page, but the same vision cannot be obtained at the beginning and end of reading. Regardless of whether the upper binding holding surface of the upper binding holder is flat or the holding surfaces of Tables 1 and 4 are formed so as to form an obtuse angle, both are fixedly mounted, and They are not responding to changes.

[0007]

[Issues to be solved]

 Therefore, when reading the bookbinding while lying in a supine or sitting position, ensure that the bookbinding is maintained and that Tables 1 and 4 are retained so that the same vision can be obtained on the left and right pages regardless of the number of spread pages. The purpose of this invention is to provide a reading platform that can respond to the surface.

[0008]

[Means for Solving the Problems]

 An object of the present invention is to provide a bookstand including a pedestal, a holding column erected on the pedestal, and a bookstand body attached to the column head via a connecting member. The look-stand body is composed of a frame member, a movable member and a spread-page holding member, and the spread follows the change in the number of left and right pages as the bookbinding placed on the bookstand body is read. This can be achieved by the reading stand according to claim 1 having a structure that is kept flat.

[0009] Next, the object is that the frame member is provided with a plate-shaped backing member, and is projected and protruded in the same direction at upper and lower ends of the plate-shaped backing member, and has a same planar shape. And a plate-like top plate member and a base plate member attached to the upper and lower ends of the plate-shaped backrest member at the center edge thereof.

[0010] Also, the object is to provide two plate members having the same planar shape, wherein the movable member is axially fixed to each of the left and right end portions of the top plate member and the bottom plate member in a symmetrical manner in a double open manner. The two plate members are axially attached to the left and right end portions of the plate-shaped backing member so as to have the same inclination angle with respect to the plate-shaped backing member in a state where the two plate members are inclined with respect to each other. A cover holder for retaining the bookbinding cover is attached to the outer upper surface, and a cover insertion hole for sliding the bookbinding cover is formed on the inner upper surface of the right side plate for holding the bookbinding cover. It can be attained by the reading stand according to claim 1, which is provided with the following plate member.

[0011] Further, the object is that the double-page spread pressing member is provided with a page pressing and a shaft mounted on a front edge portion inclined inside the plate-shaped base plate member and a side edge portion of a top binding book cover holding plate material. This can be attained by a reading stand according to claim 1, which is a page holder attached.

Still further, the above object can be achieved by the reading stand according to claim 1, wherein the inclination angle is 18 degrees to 20 degrees.

[0013] The object can be achieved by the reading stand according to claim 1, wherein the cover retainer for binding the bookbinding cover uses a biasing force of a spring.

[0014]

[Embodiment of the invention]

 The lectern of the present invention comprises the lectern main body 1 and a support for supporting them, and is used in a supine or sitting state. The book stand body 1 according to the first aspect of the present invention includes a fixed frame member, a movable member incorporated in the frame member, and a page holder for preventing a double-page spread from drooping or turning over. .

The operation of the lectern table main body 1 will be described below with reference to the schematic diagrams of FIGS. 8 and 9. In the case of a Japanese book, since it opens to the right, the bookstand body 1 is configured to conform to this. First, the table 1 (B1) of the bookbinding B is inserted into the cover insertion hole 60 and slid, and then the table 4 (B4) on the opposite side is held by the cover retainer 50 on the cover holding plate 5. . FIG. 8 schematically shows this state. This is the state when reading a Japanese book begins. Since the number of pages is small on the side of Table 1 and the number of pages on the side of Table 4 is large, a spread can be formed by rotating the holding plate 6 in Table 1 where a step can be formed. You can see that it is kept flat. FIG. 9 shows a state near the end of reading. The situation opposite to that in FIG. 8 is shown, and it can be seen that the cover holding plate members 5 and 6 follow the change in the number of pages well. Although Table 4 (B4) is not moved because it is sandwiched on the cover holding plate 5 by the cover presser 50, Table 1 (B1) slides in the cover insertion hole 60, so that the number of pages of the upper bookbinding is increased. It is possible to rotate following the change of.

The invention of claim 2 provides a framework structure that should serve as a skeleton in order for the above-mentioned reading table main body 1 to exhibit the above-mentioned operation.

According to a third aspect of the present invention, there is provided a movable member for allowing the above-mentioned reading table main body 1 to perform the above-described operation.

The invention of claim 4 provides a means for preventing the pages of the bookbinding double-page spread during reading from dropping or turning over.

According to the invention of claim 5, the optimum inclination angle to be taken by the cover holding plates 5, 6 with respect to the plate-shaped backing plate is set to 18 to 22 degrees. This is because, in order to easily follow the change in the left and right thickness of the spread in the bookbinding of about 300 to 500 pages, and to keep the spread in a flat shape, this angle has been recognized as the best rule of thumb based on empirical rules.

The invention of claim 6 employs a cover presser 50 mounted on the cover holding plate member 5 using the biasing force of a spring. It is adopted in consideration of convenience, workability, and purpose, and cooperates with the cover insertion hole 60 to assist the above-described operation of the lectern base.
