This is only one of the five thousand years of change - spring skates

"Popular Science" published a few days ago, the top ten "Best Invention Award, a grassroots" interesting invention flavor. Spring skates David · broye, the usual management near Toronto apartment, but he would in any free time to engage in a practice their favorite inventions - such as solar smoke detectors, or go to In addition to the the senile plaques creams. 1998, Blois is the local ice rink skating, a novel idea suddenly got into his head: can not invent a assembly spring skate, skaters can make even more freedom to control the intensity of their own actions? Blois decided to put into practice the idea. Despite the difficulties of the research process is beyond the imagination, but when the Patent Office informed also never had the same idea with their own time, he felt the excitement of an innovator. It can be said, by humans from skates invented that day, whether early use of tempered beast Piga whale bones, or the use of carbon fiber and stainless steel, for 5,000 years, the basic structure of the skates did not happen too much change: put the feet boots, ice skates and things are tied together. Blois increase for the Big Three, a new element - spring. He has produced a prototype shoes, Blois in the two cavities are located at the toe and heel originally installed skates into the two compression springs, then put skates fitted. So when skating began to move their feet, the spring will be compressed the income accordingly skates skates within a few millimeters. When skaters lifted his foot, the spring will release energy before closing accumulator, skates back to the initial position, skater won additional boost power. Blois invention creative, it is a pity that his own do not have enough money to hire professionals to conduct further study of fatigue experiments. Fortunately, a lot of people have seen - and now a sports therapist Mike Austin said that athletes wearing the new shoes, just after toe force rather than the previously required the entire soles force can forward , and continued skating 20 minutes will not feel any fatigue. This can effectively reduce the damage to the muscles and joints.
