The folding chair is a kind of seat made by using the folding principle and folding structure. This kind of seat is convenient, fast and takes up little space. And a kind of seat is made, which is convenient, fast, and takes up little space. Seat Type.
First of all, folding chairs can be divided into indoor and outdoor according to different usage scenarios.
The creative point of the indoor folding chair lies in the combination with other furniture, the stacking of multiple chairs, and the folding into a bed. But due to the small interior space, chairs take up space and can easily damage the walls. The design principle is the integration with the decoration environment, and the specific use scenarios are hospitals, restaurants, schools, etc. or households. The creative point of the indoor folding chair lies in the combination with the backpack, the combination with the table board, the use of single person and multiple people, as well as the adjustment of height and angle, which can sit or lie down. But it is not easy to carry, too heavy, will increase the burden of going out. The design principle is portability, and the specific use scenarios are outdoor places such as fishing, picnic, beach, and art sketching.
Secondly, the folding structures in folding chairs can be classified into the following categories, some of which are also suitable for other folding products.
1. Retractable
Through a fixed node, the different parts are rotated and twisted, and finally the folding effect of the concentric structure is realized.
2. Combined
Combining multiple monomers is convenient for storage and reduces the space occupied.
3. Spiral
The design is based on the working principle of screws and nuts, and the lifting and folding of the seat is realized by the rotation of the connection between the seat part and the support part of the folding chair.
4. Inflatable
It is especially suitable for inflatable folding chairs with small space and low frequency. Mainly use wear-resistant, corrosion-resistant elastic materials, mostly nylon or plastic.
5. The flexible material relies on the plasticity and fold ability of the folding chair itself. It occupies a small space and is easy to carry and transport. It can be displayed in the indoor home environment and can be placed outdoors.
Thirdly, ergonomic analysis of Folding Chairs
1. Design according to human body size and different sitting postures
2. The seat needs to be stable
3. Reasonable design of folding backrest
An excellent folding chair is evenly distributed on the hips, thighs and knees according to the person’s weight, so that the nerve tissue and blood circulation are not overly compressed.
Therefore, the design of the folding chair is also very particular. It must conform to the structure of the human body, so that people can stay active after sitting for a long time.
