Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a desk lecturing table for holding a book such as a musical score in a state where the book is open and tilted.

[0002]

2. Description of the Related Art A table-top reading stand installed on a table and standing up by opening a book has a back plate which has an area equivalent to that of the book in an open state and is installed so as to be inclined rearward, and the back plate is placed rearward. It consists of a stand that supports from. It is desirable that this desk-top reader can be installed at any tilt angle with one touch, and that the tilt angle can be easily changed. Further, if it is stable against pressure from the front at all inclination angles, writing on a book can be carried out smoothly, which is convenient.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a table-top reading table which can be installed at an arbitrary tilt angle with one touch, and the tilt angle can be easily changed, and which is stable on the upper surface of the desk.

[0004]

The desk-top reading table of the present invention comprises a back plate having a shelf edge on the front surface and a stand swingably attached to the back surface of the back plate. The rear corner of the ground and the front corner of the ground contact surface of the stand are curved surfaces and have slip stoppers, and the stand is swingable by its own weight.

[0005]

According to the present invention, when the back plate is set substantially upright on the table and tilted rearward, the stand swings by its own weight and the ground surface of the stand comes into contact with the upper surface of the table. Stablely set up a book stand. Since the rear corner of the ground contact surface of the backboard and the front corner of the ground contact surface of the stand are curved and have a non-slip surface, the desk-top reading table can be installed stably with one touch at any inclination angle.

According to the second aspect of the present invention, the width of the ground contact surface of the stand is set to 2/3 or more of the width of the back plate. As a result, it is stable against pressure from the front and is convenient when writing on a score or the like with a writing instrument. According to the third aspect of the invention, the position of the ground contact surface of the stand is set somewhat above the position of the ground contact surface of the back plate. As a result, first, the backboard is erected substantially vertically on the upper surface of the desk, and then the stand is rocked by tilting the backboard to the rear of the desk, so that the tabletop can be installed at an arbitrary inclination. You can also change the tilt angle with one touch by pulling the bottom part forward.

In the structure of claim 4, since the curved surface is a cylindrical surface and the slip stopper is a friction material provided on the curved surface, it is highly practical. According to the structure of claim 5, since the handle is provided on the upper portion of the back surface of the back plate, the installation and the inclination angle can be changed with one touch. According to the structure of claim 6, since the writing stand is provided on the side portion of the back plate, it is convenient when writing on a score or the like. If the writing stand is detachable, it will not get in the way when folded and stored.

BEST MODE FOR CARRYING OUT THE INVENTION The first embodiment of the present invention shown in FIGS.
Description will be given together with examples. Desk lectern (hereinafter, lectern)
1 has a rectangular back plate 2 which is installed on a desk surface such as a desk and inclined rearward, and leans against an open book such as a musical score. Behind the back plate 2, a stand 3 for supporting the back plate 2 in an inclined state is swingably attached.

A shelf edge 4 on which a book such as a musical score is placed is provided at the lower end of the back plate 2 so as to project forward. In this embodiment, the shelf edge 4 is formed by fixing a metal angle member 41 to the lower end of the back plate 2. The back plate 2 has a curved surface 22 formed by a cylindrical surface having a cross section of about 1/4 arc at the rear corner of the lower surface 21 that comes into contact with the desk, and a non-slip material 23 made of a friction material such as rubber is attached. There is. In this embodiment, the curved surfaces 42 at the corners of the angle member 41 are used as they are for about 1/4.
A curved surface 22 formed of an arcuate cylindrical surface is formed.

The back plate 2 may be a wood plate, a plywood plate, a resin plate, a composite material plate of resin and wood, or a metal plate such as aluminum or iron. When a resin plate, a composite plate of resin and wood, or a metal plate such as aluminum or iron is used, the back plate 2 and the shelf plate 4 can be integrally formed, and the productivity is excellent. Further, when the metal plate is formed by bending, the curved surface 22 can be formed at the same time. When plywood is used, surrounding the edge with a frame improves durability and at the same time improves appearance.

In this embodiment, the stand 3 is made of a wood plate having an inverted T shape, and is rotatably connected to a strip plate 31 fixed to the upper portion of the back surface 2A of the back plate 2 via a hinge 32. . The stand 3 includes a leg portion 33 having an upper end fastened to the hinge 32, and a wide leg portion 34 that comes into contact with the ground contact surface.
As shown in FIG. 2, in the bookstand 1, the lower surface 35 of the foot portion 34 is set higher than the lower surface 21 of the back plate 2.

In this embodiment, the width A of the foot portion 34 is equal to the width of the back plate 2.
The width B is set to be substantially the same as the width B. This is because the stand 3 has an action of setting a low center of gravity so that the stand 3 can freely swing around the hinge 32 as a fulcrum by its own weight, and also improves stability at the time of installation. Foot 3
The width A of 4 is 2/3 B ≦ A ≦ 4/3 of the width B of the back plate 2.
B is important from the viewpoint of ensuring stability.

A front surface of the lower surface 35 of the foot portion 34 is a curved surface 36 formed of a cylindrical surface having an arc of about 1/4, and a non-slip material 37 made of a friction material such as rubber is attached thereto. The anti-slip material 23 or the anti-slip material 37 is formed on the curved surface 22.
Alternatively, it may be provided over the entire width of the curved surface 36. Further, when the back plate 2 or the stand 3 is made of resin, it is possible to form irregularities or the like on the curved surface 22 or the curved surface 36 and use it as the non-slip surface as it is.

As shown in FIG. 3, the bookstand 1 is installed on a desk surface 10 such as a desk with the back plate 2 tilted backward at an arbitrary inclination angle and the stand 3 supporting the back plate 2 so as to support the back plate 2. Place the book such as the score in the open state in 2 for use. When installing the book stand 1, as shown in FIG. 4, the back plate 2 is held vertically at a desired position on the desk surface 10 by grasping the side or top of the back plate 2.
The lower surface 21 of is installed. Next, when the back plate 2 is tilted forward and backward, the lower portion of the stand 3 swings backward due to its own weight, and a desired angle can be set.

At this time, the rear angle of the lower surface 21 of the back plate 2 is 1 /
The curved surface 22 is a cylindrical surface having four arcs, and the foot portion 3
The front angle of the lower surface 35 of No. 4 is a curved surface 36 formed of a cylindrical surface having a quarter arc, and an anti-slip member 37 is attached. Therefore, it can be stably installed at an arbitrary angle. In addition, since the width A of the foot portion 34 of the stand 3 is approximately the same as the width B of the back plate 2, stability is maintained even if external force (pressing force) is applied to the surface of the back plate, such as writing on a score with a writing instrument. it can.

To change the inclination angle of the back plate 2 to approach the vertical direction, the foot 34 of the stand 3 is lifted from the ground contact surface and rocked by gripping the upper portion of the back plate 2 and rotating it in the standing direction. Therefore, the tilt angle can be changed with one touch.

As shown in FIG. 1, it is convenient to install a writing instrument stand 11 on the side of the back plate 2. Further, if the writing instrument stand 11 is made detachable, it can be detached and made compact when folded and stored in a bag or the like.
