Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a podium, which is a reading aid.

[0002]

[Prior art]

 Conventionally, there are bookshelves on a desk that are constrained on the surface of paper by springs or gravity, but this is troublesome because both hands and fingers are required for the constraint release operation that occurs each time the page is turned. In addition, there was no book stand that could be read from the table in a sitting position and easily moved to a inverted position in an inverted position.

[0003]

[Chief trying to solve the problem]

 Conventionally, various improvements have been made to devise a bed-mounted reading table for beds, but reading on a desk, which is a reading mode for ordinary consumers, and subsequent folding on a folding place. There was no bookshelf that could be easily transferred to inverted reading in a recumbent position.

The bound book has the property of returning to the original closed shape even if it is opened on the book shelf, and requires a strong binding force to obtain a flatness that is easy to read. In particular, there is no effective method for restraining books in the inverted state, and releasing the restraint is cumbersome and impractical.

The present invention has been made to solve the above problems of the prior art, and its purpose is to read while sitting or lying down, which is the reading mode of ordinary consumers. It is a book stand with excellent mobility, and in particular, it has a stable support mechanism in the inverted state and the page can be turned with a light operation of one finger, and the volume of the left and right pages changes as the reading progresses. The aim is to provide a more practical book stand by realizing a paper surface holding mechanism that can easily handle the above, and can always maintain the flatness of the paper surface.

[0006]

[Means for Solving the Problems] In order to achieve the above object, a book stand according to the present invention has a triangular trapezoidal shape formed by connecting a book rack (1), a bottom plate (2) and a support plate (3). There is a main body of a book stand, and a groove (4) for fitting a spelling part of a book is provided in the central band of the book rack (1). An inverted support plate (5) is movably connected to both end portions of the writing plate (1), and is supported by the side edge of the bottom plate (2) and the tip of the inverted support plate (5) when inverted. Further, the receiving plate (6) is movably connected to the inverted supporting plate (5) so that the side edge of the cover of the written book can be supported. (Fig. 1) (Fig. 2) The inverted support plate (5) and the receiving plate (6) can be folded and stored along the side edge of the writing plate when not in use. (FIG. 3) A pair of paper surface pressing devices (A) and (B) are provided on both lower sides of the writing board (1). The paper holding device has a base plate (13), an intermediate plate (14), and a holding plate (22) connected by axial screws (16) and (24), and has two joints and can freely bend and stretch. The strength of the paper presser can be adjusted by the tightening strength of the shaft screws (16) and (24) at the joints. Teflon washers (17) (18) (26) (27) are fitted to the sliding parts to keep the joints moving smoothly while maintaining the tightening strength and to prevent the nuts (20) (29) from loosening. (Figure 4)

The Teflon washers (17), (18), (26) and (27) used in the paper pressing device in the present consideration need to have less friction than other sliding parts, so the friction area and the friction coefficient should be considered. Other materials may be used as long as they are.

The inverted support plate (5) may be pulled out from the main body and stored without being expanded and folded.

The inverted support plate (5) may be fixed to the main body of the book stand, or may be attached to the main body of the book stand only when necessary.

[0010]

In the case of plane reading on a desk, the inverted support plate (5) and the receiving plate (6) are folded, and the booklet is inserted into the groove (4) to open the book. The angle of the intermediate plate (14) is adjusted according to the thickness of the left and right opened pages, and the bulge on the paper surface is held by the holding plate (22). To turn a page, first remove the holding plate (22) by pulling up the upper corner of the paper surface to be turned over with your fingers, and after turning, move your fingers to the lower corner of the paper surface and pull it under the holding plate on the opposite side. I can. During this operation, pressure adjustment of the holding plate is unnecessary. As necessary, the height and pressure of the presser plate (22) that accompanies changes in the bulk of the left and right pages as the reading progresses may be applied to the presser plate (22) and the intermediate plate (14) with one fingertip of the hand as necessary. . The pressure of the paper holding device is adjusted by moving the tip of the holding plate (21) up and down with your fingertips. When shifting to inverted reading, the inverted support plate (5) on the inverted side is opened as it is, and the receiving plate (6) is further developed to support the side edge of the front cover of the book. The inversion of the book stand is the rotation angle with the side of the bottom plate (2) as the inverted rotation axis (11), but it does not become 90 ° of complete inversion, and the thickness, weight and lighting angle of the book. , It is adjusted by moving the tip position of the inverted support plate (5) according to the height of the line of sight of the reader.

【Example】

 Examples will be described with reference to the drawings. In Fig. 1, the supporting plate (3), the writing plate (1) and the bottom plate (2) are spliced on the sides that are in contact in this order with a hinge, etc., and the stopper plate (9) is provided on the end side of the supporting plate (3). The bottom plate (2) is locked at the end of the bottom plate (2) to form a triangular stand and can be folded. The groove (4) in the central band of the writing board (1) is provided by cutting out the writing board (1). The material used is a plate-shaped material such as wood, paper, or synthetic resin. For the inverted support plate (5), the receiving plate (6), the paper holding devices (A), (B), etc., a punched material of a metal plate or a molding material of synthetic resin is used. For the parts around the shaft, general commercial products are used.

[Effect of device]

 Since the present invention is configured as described above, it has the following effects.

By providing the inverted support plate (5) and the receiving plate (6), it is possible to change from a flat reading in a sitting posture to an inverted reading in a recumbent posture, so that it is possible to read from a long time reading. Physical fatigue that occurs is prevented, and it is possible to read comfortably.

By moving the tip position of the inverted support plate (5), the inverted angle of the paper surface changes, and it is possible to obtain an appropriate light receiving angle for indoor lighting from the ceiling surface, and thus comfort can be obtained. It was

[0015] Compared with a conventional book stand in which an arm is expanded and contracted while being fixed to a bed, it is characterized by being movable anywhere, and has a simple structure, is convenient, and is inexpensive.

[0016] In a conventional book table in which an arm is extended and contracted while being fixed to a bed, a plurality of strong and powerful restraint devices are necessary to prevent the book from falling when inverted, and this is why page turning is performed. Since it requires both fingers to release the constraint each time, it was bothersome and not practical. In the present invention, the weight of the book is supported by both the groove (4) and the receiving plate (6), and the book holders (A) and (B) prevent the book from falling down from the book shelf (1). Therefore, a special restraint device is not required, and the page turning operation can be performed unconsciously with a light motion of one hand, and the feeling of being put into reading is not lost.

If the pressure on the paper surface is too strong, an extra force is required to release it, and if it is weak, the flatness of the paper surface cannot be secured, but in the present invention, it is adjusted by the shaft screws (16) (24). Since it can be adjusted, the optimum presser foot pressure can be easily obtained, and there are no problems.

Since the Teflon washers (17), (18), (26) and (27) are used for the joints of the paper pressing devices (A) and (B), the joints have smooth movements as well as flexible holding power. I was able to do so, and I had an ideal function similar to a finger.

When moving the intermediate plate (14) or the presser plate (22), the Teflon washers (17), (18), (26) and (27), which have the least friction, contact the sliding parts of the joints. The nuts (20) and (29) do not loosen because they slide only while moving.
