Description

Reading table {BOOKSTAND}

The present invention relates to a reading stand for fixing and supporting a book or reference material, and more specifically, the joint member is connected to the book support member and the base in a pivot and ball joint manner to easily adjust the height, angle, and distance of the book. It is about reading desk which we can use in place outside desk.

In general, the reading table is used on the desk and keeps the distance between the user and the book constant. Various reading desks have been disclosed, such as reading desks that can be used for situations such as lying down or reading in an uncomfortable manner.

Most existing reading desks have a limited function that can only be used on a desk. The reading stand, which can be used in places other than the desk or in unusual situations, such as when a user lies down or sits on the floor and reads a book, has a complicated structure and requires a lot of preparation procedures. This product is widely used on the desk, and has a large number of locking jaws on the back of the book support plate to adjust the book's inclination, and is a product frequently used during computer work. For this purpose, various reading stands are disclosed, such as a reading stand for fixing heights on two parallel support feet, and for fixing books downward using springs and hooks.

1A is a perspective view of a reading stand disclosed in the related art. The bookstand shown in FIG. 1A includes a book support plate 12 supporting the back of the book, a book support 14 having a latching jaw 16 for adjusting the book support plate 12 at a predetermined angle, and one side of the book. A fastener 18 for fixing is provided. 1a has a problem in that the user needs to look at the book by leaning his head because only the tilt of the book is adjusted without adjusting the height. If the user leans his head for a long time, the neck is bent or the waist is bent, which may cause a change in body shape and may also cause myofascial pain syndrome. Myofascial pain syndromes are associated with many pains. Experts say they can prevent myofascial pain by sitting down like a waist and pulling your jaw toward your chest and not bending your head more than 15 degrees from your neck. In order to solve this problem, a hinged reading stand is disclosed in which hinges are connected to both ends of a connecting rod to connect a book support member and a base. The hinged reading stand can adjust the height of the book compared to the reading stand of which only the tilt can be reduced a lot of bow, but there is a limit to the height adjustment. Lowering the position of the book lowers the tilt of the connecting rod so that the book comes out, and raising the position of the book raises the tilt of the connecting rod and the book retreats backward. As you adjust the book's position, the distance between the user and the book also changes, so you have to move the whole book. If the distance between the book and the eye is not properly adjusted, eye fatigue may increase and vision decreases, and the distance between the book and the eye may be distorted, causing a false impression.

Figure 1b is a perspective view of a reading table disclosed in the prior art. The reading stand shown in FIG. 1B includes two support feet 22 positioned at both sides of the user, a height adjuster 24 fixed to the ends of the support feet 22, and a book support plate for fixing the book downward. (26) is provided. The reading stand shown in FIG. 1B requires a large number of connecting rods and accessory members, and has a limited function that can only be used when reading lying down. In addition, the reading desk shown in Figure 1b is bulky, high manufacturing cost, requires a lot of preparation procedures, it is not suitable for use for reading books sitting on the desk or floor. There is also disclosed an all-round reading table using multiple joints.

Figure 1c is a perspective view showing a universal reading table using a conventional articulated articulation. The universal reading table shown in FIG. 1C includes a rectangular base 32, a vertical rod 34 fixed to the base, a connecting rod 36 fixed to the top of the vertical rod 34, and a book support member 38 for supporting a book. . The reading stand shown in FIG. 1C can move the book to various positions using two connecting stands 36. However, since the vertical bar 34 is completely fixed to the base 32 and does not roll back, the movement range of the book is limited. When the book is moved away from the base 32, the center of gravity of the book is far from the center of gravity of the base 32. When the center of gravity of the book is away from the center of gravity of the base 32, the connecting rod 36 becomes a moment arm and a load of the book is applied to generate a rotational force on the base 32. When the rotational force is generated, the reading stand becomes unstable, and in order to overcome this, the base must be made large or fixed to the base, but there are limitations in place and inconvenience of use. If the vertical rod 36 is fixed to the base 32 and is not rotated, the distance between the center of gravity of the book support member 38 and the center of gravity of the base 32 cannot be reduced, thereby limiting the movement range of the book. Since the plurality of connecting rods 36 are connected to the vertical rods 34 that rise to a certain height, the volume becomes large, and the restriction of the place and the manufacturing cost also increase. In addition, if the connecting rod 36 is directly connected to the vertical rod 34 with a screw, the connecting rod 36 generates continuous friction with the screw every time it flows, which may cause wear of the screw and damage to the connecting part. Wear of screws and damage to the joints will result in a loss of joint performance and the book will be unstable. Also disclosed is a multi-joint reading stand using a multi-joint fixed to one side of a desk. The articulated reading table is adjustable in height, distance and angle, but has a limitation that the product is bulky and must be fixed to the object. It is also inconvenient to move the reading table to another place. In addition, when the book is far from the fixed point, a large rotation moment is generated in the connecting rod, and a large load is applied to the connecting portion. In order to overcome this load, high rigidity connecting rods and joint members are required, which increases the manufacturing cost.

In order to solve the above-mentioned problems, a first object of the present invention is to provide a reading stand that is simple in structure and low in manufacturing cost.

The second object of the present invention is to provide a portable reading stand that can be moved and fixed up, down, left and right, and easily disassembled and assembled.

The third purpose of the outbreak is to provide a versatile reading table that can be used by the reader to lie down, lean or sit on the floor, regardless of a desk or floor.
