Unpowered amusement equipment refers to the active experience type equipment that has the characteristics of amusement equipment without using any unnatural external force and energy. The overall shape and scientific and technological content are a comprehensive amusement facility that integrates jumping, climbing, drilling, sliding, swaying, rolling, rocking and other functions into one. 

             Domestic and foreign origin 

As the forefront of the world's outdoor unpowered children's playground products, Europe and the United States all represent the world's top level in terms of industry safety standards, product design and industrial design, and process quality standards. 

Beginning in 1866, a public elementary school in Boston established the first outdoor public children's playground, including swings, seesaws, sand, etc., which truly began the era of unpowered amusement equipment. 

The unpowered playground has developed to a brand new stage, starting to base on children’s behavior and psychological research, including a series of social disciplines such as landscape design, child psychology, and social environmental science, and comprehensively applied to the current stage of unpowered children’s playground design , The whole consideration of product application. 

Before the 1980s, China basically had no manufacturers, no industry associations, and no national standards. Beginning in the 1980s, China began to set up relevant industry associations, and some manufacturers, whether small workshops or small-scale production and processing plants, went abroad and began to learn American production techniques and methods. 

After entering the Internet + era, China's industry information has become more and more symmetrical with Europe and the United States, and advanced production technology, design and development concepts, including industry safety standards, have been introduced one after another. So far, China's market has changed drastically, from quantity to quality, products to diversification, and quality to differentiation. 

European and American countries have compulsory safety standards, and product design must also have high rigid requirements. China, which has just started, tends to follow suit, imitating its shape, but its core structure design and industrial design are very weak. European and American countries have different types of manufacturers with a variety of themes, styles, materials and designs. However, China still has a certain gap with Europe and the United States in terms of appearance design and color matching. 

Comparing China's material technology and foreign anti-rust treatment, including the strength of the connection piece, the vividness of the color, the anti-ultraviolet rays, and the degree of anti-aging, there are big differences. 

Classic children's play equipment 

These amusement spaces not only integrate the experience of the five senses, but also a large number of amusement elements, materials, plants and artworks, which provide a good opportunity for development and exercise for children's development in flexibility, balance, coordination and strength. 

Various equipment and activities form an adventure and interesting play area. The change of plant configuration and height difference divides the amusement space, forming an independent and unified area in the playground, so that everyone can have fun here. 

In the design process of all equipment, it is understood that taking risks and meeting challenges is very important in the growth process and entertainment life of children. As a conventional equipment, slides are designed with more novel and adventurous methods, breaking the convention and starting to take risks. Play is the most important way for children to develop their abilities. 

The main purpose of designing this kind of climbing amusement equipment is to not completely exclude risks in entertainment activities or set up various risk aversion facilities for children when performing climbing nets. It's like wrapping children tightly in cotton wool to prevent them from being hurt.
