The study desk is a new, scientific, humanized and practical learning aid, which is suitable for children from 3- 18 years old to teenagers. It can be adjusted up and down, and the desktop is inclined.
Learning desk is a tool made through in-depth study of ergonomics, human mechanics and human physiology, combined with human visual principles, chromatics and psychology, and through numerous data collection, experiments and argumentation. Learning desk and traditional desk are two completely different concepts. Hand-held (screw-fixed) hand-held lifting, the things on the table must be removed before operation, the screws can not be reused, and it is easy to wear and slide lines.
1. The inclined desktop design with adjustable angle allows users to sit up straight naturally and adopt comfortable reading and writing posture. And you can adjust the angle at will according to different learning States, such as reading, writing, drawing, calligraphy and other States, and you can use different desktop angles. On the one hand, users can easily write and read without greatly bending the spine, so that the body can relax and lean back on the chair; On the other hand, through the desktop with adjustable height and angle, the sight distance is naturally kept in a scientific position, instead of trying to keep straight like a traditional desk. That is, the table adapts to the human body, not the human body adapts to the table. At present, the tilt mode of common products in the market:
The first generation has only a fixed slope.
The second generation has a fixed slope and flatness (low grade).
The third generation has segmented (4-8 segments) slope adjustment (mid-range).
Fourth generation stepless (arbitrary position) adjustable inclined plane (advanced function)
The advantage of randomly adjusting the desktop angle is not only convenient to operate, but also more humanized and safer. Desk has entered the era of humanized fine-tuning of desktop angle.
2. Height lifting design. Users can freely adjust the most suitable desktop height according to the height of different age groups. They are no longer bothered by height in their study and work, but can master comfortable sitting posture by themselves. The study desk grows up with the children like good friends. At present, the common hoisting methods are:
First-generation hand lifting (after the desktop is lifted, it is bolted, and it must be operated by two people)
The second generation of hand crank (the operation becomes simple, but it takes time to raise and lower it greatly)
Third generation air pressure (simple operation, fast lifting)
At present, manufacturers are developing electric lifting platform, which can be numerically controlled or remotely controlled, but the cost is too high and it will take time to popularize it.
4. Practicality of countertop materials. Because of the big design concept since childhood, the most important material characteristic of the study table is durability, otherwise it won't take long even if it rises and falls greatly. Therefore, the traditional solid wood board and painted wood veneer are no longer suitable for the study table. In addition, the modern study desk has higher requirements from the perspective of human nature, such as easy scrubbing, soft reflection and beautiful appearance. At present, melamine board is widely used in low-priced products, and its physical and chemical properties are acceptable, but it is easy to degum and crack under impact. High-end products adopt American Fumeijia's MSI fireproof board, which has super high impact resistance, wear resistance and deformation resistance, and is the most advanced table top material at present.
5. Space utilization rate. A good study desk is not only functional, but also a piece of furniture, which should be considered from the perspective of space utilization. There should be enough space on the desk to put commonly used books and stationery. On the other hand, it is a writing desk now, and it may become a computer desk as needed in a few years. A few manufacturers advocate leaving a groove in front of the desk for the child's body to embed, saying that when writing, the arm can be completely supported by the desktop without hanging. More people in the industry think that this is inappropriate for two reasons: first, it will undoubtedly reduce the already insufficient desktop area, which can only be used for writing, and it will be even more stretched for computer desks; Second, this ditch will not grow bigger with the growth of children. Will a 3-year-old child and an 18-year-old adult experience the same in this hole? Therefore, it does not conform to the "growth" concept of the study table. Thirdly, the design of restricting activities obliterates children's nature and does not conform to the universal concept of furniture design. After the author's experiment, the conclusion is that as long as the desktop is spacious enough, the arm can be completely supported when writing on the straight desktop.
6. The materials are environmentally friendly. Learning desks are generally used by children since childhood, and children's resistance is much worse than that of adults. Therefore, the international E 1 standard must be strictly implemented in the formaldehyde emission index (the so-called E0 level is a unique standard in China, only equivalent to the international E 1 level). The surface of the plate must be wear-resistant, scratch-resistant and dirt-resistant, and the contact surface is not allowed to have sharp corners. The whole structure is firm and not easy to shake. By the way, the highest international standard of this kind of products is: Children's greenguard.
7. The use of the book board in front of the desk, because the desktop is smooth, tilting the desktop will make the books slide down, so you need an accessory that can block the books. Different manufacturers have different designs for this, and the most common designs are 1. Aluminum alloy pen slot book stand has the advantage that some stationery can be placed; 2.PU book stand is extremely skin-friendly and wrist-protecting, and it is also very suitable for putting the keyboard on the desktop in the future.
After continuous improvement and innovation, the learning table lifting mechanism has formed five stages. Due to the huge difference in production costs, these four products coexist in the current market.
