1946 American Fred Morrison invented the first frisbee.
Wham-o Company obtained the exclusive distribution right of Fred Morrison Frisbee on 1957.
Wham-o Company officially signed the patent right of Fred Morrison on 1958.
1964, Ed Headrick of Wham-o company created the first Pro frisbee after six years of research and development.
From 1964~ 1970, Ai-Hedrick finally determined the diameter and weight of the Pro disc through several sets of die tests.
At the same time, on the basis of Pro, play series: ordinary, super Pro, master.
1972~ 1975 Wham-o develops a new generation of products from the above four models: world-class series.
World-class series include: WC-97g, WC- 1 19g, WC- 14 1g and WC- 165g.
Then all the frisbees in the world were designed from these two models and eight kinds of frisbees.
1978 Jim Cornell, one of the earliest freestylers, founded the scatter company, which was first improved by Pro.
Upgraded version of Sky-pro 125g.
In 198 1 year, Jim developed and improved the world-class 165g: two creative disks, Superstar and Star.
Ultra-Star 175g is recommended and approved by UPA for competition. (UPA has been renamed USA-Ultimate).
Sky-Styler 160g is a free fancy sports disc recommended and recognized by FPA.
1983 Dave Dunipas was the first golfer to analyze the shape of a frisbee with physics, and he started INNOVA.
Company, and designed the latest generation of golf frisbee. Based on physics, flight mechanics and fluid mechanics, it has innovated the Frisbee: 1. Modeling. 2. size. 3. The edge of the disc. 4. Raw materials. 5. Disc type classification (DD, FD, Md, Ad, Pd).
The so-called professional frisbee should be carefully designed according to the characteristics of the competition and the requirements for plates:
1. Choose a suitable and flexible raw material formula. (All companies are confidential)
2. Improve the diameter of the Frisbee for the competition. (Create a new feeling of weight/diameter ratio)
3. Improve the details of the Frisbee for the competition. (Apply for a patent in the United States)
4. Accept the player's suggestions and constantly modify the disc type. (HDX and high rigidity developed from this)
5. According to flight physics, flight mechanics and fluid mechanics, the disc is optimized and innovated. The theme of designing and developing frisbee can be found in various frisbee books published in11980 s.
We can know from the history that the frisbee was first invented by Fred Morrison, an American, and the invention right was transferred to Wham-o Company in the United States. Ed Headrick, who is in charge of the frisbee product theme, developed the first PRO frisbee after six years of research on the basis of Fred's invention. We usually call this model specialty.
Wham-o has spent at least 65,438+00 years researching the finished PRO products. The book records in detail the eight fields made by each pair of mold products over the years, including:
Mold number. Origin. Year of production. Features. Fault. Fat. Performance. Color; Color; hue
Model, origin, production year, product characteristics, problems, errors, performance, product color.
Its meticulous degree, even if it is made in China today, should be admirable if it can be thoroughly implemented.
However, compared with the research and innovation of Discraft and INNOVA after 1983, it can only be regarded as a small skill.
