Description

External folding reading bookshelf

This creation belongs to the field of furniture accessories, especially about an external folding reading bookshelf, which can solve the problem of insufficient space on the desk, and at the same time can clamp books and reduce the number or time of repeatedly moving books. This provides a comfortable reading angle for users to read comfortably, and also improves the space utilization efficiency of the desk.

Nowadays, desks or reading tables are quite common and necessary pieces of furniture, which allow people to use desks or reading tables for various document processing or book reading. However, ordinary desks or reading tables usually only provide a single flat table top for placing various books, stationery, computers and other items, and the usable area of these desks or reading tables depends on the size of the desk area, relative to the usable area. The larger the usable desktop area, the larger the size. However, the volume it occupies also increases relatively, which is quite inconvenient for limited living space. Therefore, when purchasing a desk or reading table, you must Making a choice between the desktop area and the space occupied, it is impossible to get the best of both worlds. Moreover, a flat desktop is really inconvenient for reading. Users need to frequently move the book and stand it up to an appropriate angle before reading, in order to have better reading quality. Moreover, the user must constantly move the book with both hands. It is quite inconvenient to read while supported.

In view of this, various products such as bookshelves or reading racks are currently on the market. Bookshelfs are placed on the desktop and used to hold books. Reading racks are placed on the desktop and used to tilt books at appropriate angles. Read without having to use your hands to support the book. However, these products such as bookshelves or reading racks still have many inconveniences when adjusting the tilt angle when reading books. Even when placing books, they are not stable enough and may easily lead to problems such as books slipping. Some products are not stable enough. It has the function of adjusting the angle but can only read at a fixed angle. It is quite inconvenient for users with different body shapes. However, the biggest problem in using these bookshelves or reading shelves is that they occupy the original desktop area. , making the originally narrow desktop even smaller, so it is necessary to improve it.

Therefore, the author of this article is aiming at the shortcomings of existing products for users to read books and use them. For example, it is necessary to make a trade-off between the size of the desktop and the space it takes up. As a result, most desks or reading tables in small living spaces can only have a very small space. Desktop, a simple flat desktop is not conducive to users reading books, and other bookshelf products are not stable enough or difficult to adjust the tilt angle, etc., we conducted a series of research and design, and finally created an external folding reading bookshelf 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 solution, allowing users to read books at various comfortable angles, greatly improving its practicality.
