Description

External foldable reading bookshelf

This creation belongs to the field of furniture accessories, especially about an external foldable reading bookshelf, which can solve the problem of insufficient space on the desk, and at the same time can hold books to reduce the number of times or time to move books repeatedly, and is more effective in holding books. This book provides a comfortable reading angle so that users can read comfortably, and it can also improve the space utilization efficiency of the desk.

Nowadays, desks or reading tables are quite common and necessary furniture, which can enable people to perform various document processing or book reading through the desks or reading tables. However, general desks or reading tables usually only provide a single flat table top for placing various books, stationery or computers, etc., and the usable area of these desks or reading tables depends on the size of the desk area. The larger the size of the usable desktop area is, the larger the size of the occupied area is. It is quite inconvenient for the limited living space. Therefore, when purchasing a desk or reading table, you must Make a choice between the desktop area and the size of the occupied space, but you can't have both advantages. Moreover, the flat desktop is really inconvenient for reading. Users need to move the book frequently and stand it up at an appropriate angle before reading, so as to have better reading quality. Reading in a supported state is quite inconvenient.

In view of this, there are various products such as bookshelves or reading racks on the market. The bookshelves are placed on the desktop to hold books, and the reading racks are placed on the desktop to tilt the books at an appropriate angle. Reading while putting it down, avoiding the embarrassment of using both hands to support the book. However, these bookshelves or reading racks and other products still have many inconveniences when adjusting the inclination angle when reading books, and even when placing books, they are not stable enough to easily cause books to slip. It has the function of adjusting the angle and can only read at a fixed angle. It is quite inconvenient for users of different stature conditions. However, the biggest problem in the use of these bookshelves or reading racks is that they occupy the original desktop area. , so that the originally narrow desktop becomes smaller, so it is necessary to improve it.

Therefore, the author aims at the deficiencies of existing products for users to read books and use, for example: it is necessary to make a choice between the size of the desktop and the space occupied, resulting in most desks or reading tables with small living spaces can only have a very small size. The desktop, a simple flat desktop is not conducive to users to read books, and the other bookshelf products are not stable enough or difficult to adjust the tilt angle, etc., missing. A series of research and design were carried out, and an external folding reading bookshelf was finally created to solve the problem. The lack of space on the desk can also reduce the number and time of moving books, and provide a simple angle adjustment scheme, allowing users to read books at various comfortable angles, greatly improving the practicability of their use.

One of the purposes of this creation is to provide an external hanging folding reading bookshelf, so that a box body, a shelf component, an adjustment component and a control pressure piece can be controlled by the linkage between the pressure piece and the adjustment component.
