Features: the shaft of the front blade holder, the shoe of the rear blade holder and the ice skate can be detached, and extends the time of stirring the ice.
In the early 1980s, biomechanical researchers produced the idea of improving speed skating performance with the help of ice skates, in 1985 in the Netherlands under the leadership of Professor Gerrit, scientists made the first pair of ice skates with hinges model - Klap (klap) ice skates. Nagano Winter Olympics klap ice skates on the extensive use of speed skating Winter Olympics records are broken.
The secret lies in the researchers in the shoes and ice skates near the thumb of the place installed a link device, so that the athletes stir ice center of gravity forward when the back of the blade tray and ice skates automatically separated, so that the ankle can be fully plantarflexion, increase the calf and spread the ankle muscle groups stir ice force, extend the stir ice time, and does not increase the friction on the ice surface.
Clipp's ice skates:
What's good for you is good for you. Ice skates are the core equipment of speed skaters, and the quality of ice skates has a direct impact on athletes' performance. Nowadays, speed skaters use "Clipper ice skates", and few ice fans may know that the shiny silver blades have a history of more than 100 years.
From its invention in 1884 to its mass application in the 1990s, the Clipper ice skate has traveled a long and winding road, sparking a revolution in the sport of speed skating.
In 1884, a British man named Charles Corneby was awarded the first patent for the Clipper ice skate, but for some reason, his idea was never put into practice in international competitions. was never put into practice in international competition.
In the 1980s, Dutch biomechanic Gerrit Jan van Ingen Schenau became a pioneer in the creation of the Clipper Ice Knife, writing a doctoral thesis on the subject back in 1981.
However, when he and skate maker Viking applied for a European patent, they discovered that the idea had already been patented, and that Karl Hannes of Germany in 1894 was not even the first to receive a patent for the Clipper ice skate. Between 1884 and 1937, five patents were granted based on the idea of ice skates as opposed to the movement of ice skates.
Van Ingen-Schnauer was unaware of the previous ideas about the Clipper ice skate, and as a biomechanic, he saw the shortcomings of traditional skates, where the ice blades were fixed to the skates. He reasoned that speed skaters couldn't fully utilize all their power because they had to keep the blades off the ice before their ankles and knees were fully extended to prevent the tips from slicing through the ice, which would slow them down.
Since the early 1980s, van Ingen Schenau has used hinges and springs on his skates so that the heel of the skate can be raised and the skater can fully extend his knees and ankles without having to keep the blade away from the ice. Although initially skeptical of his invention by some of Holland's top skaters, the scientist continued to refine his invention in collaboration with manufacturers.
It wasn't until the 1994/1995 season that a group of young skaters from the South Holland Provincial Selection Team began to use Clipper ice skates in competition. Their rapid progress caught the attention of former Dutch all-around speed skating champion and Dutch national team women's coach Sije van der Lunde, who in the summer of 1996 persuaded her team to try out this innovative piece of sports equipment.
When 23-year-old Toni de Jong won the European all-around speed skating title in 1997, the rest of the international speed skating world followed her example, and almost everyone at the 1998 Winter Olympics in Nagano used Clipper Ice Skates ice skates.
It was from that point on that Claypool Ice Skates sparked a revolution in speed skating. During the 1997/1998 season, nine out of ten men's and women's world records were broken because of this innovation. The unheralded Clipper ice skate became a highly sought-after speed skating weapon.
