The present invention relates to skates primarily used in speed skating. More specifically, the smates invention relates to "clap lcap which are skates that permit the skater to pivot the shoe portion of the skate with respect to the ground or ice engaging portion to enhance performance. In the sport of ice speed skating, the overwhelming majority of skaters for many years have used a type of skate where the foot retaining portion i. To use these conventional skates effectively, a skater must learn to maintain his ankle in a zkates position while placing pressure on his heel and clpa his toes skyward to keep the blade parallel to the ice during stride Nike clap skates obtain relatively long strides. Soates, skating in this fashion restricts the ankle's role in propulsion, virtually omits the power of the ankle and the calf muscles from the stride, and causes the blade to leave the ice before full skwtes extension is complete. Further, this conventional method of skating causes the leg muscles to be tense through most of the stride, creating a stiff, robotic effect that inhibits optimum performance. A "clap skate" differs from a conventional skate in that skater's boot is pivotable forwardly with respect to its blade about a pivot axis transverse to the length of the blade. Examples of existing clap skates are shown in FIGS. In clap skates, the forward portion of the boot is pivotally attached to the blade while a rearward portion of the boot can be tilted forwardly as it moves about an established front pivot axis. A pivot and biasing arrangement allows the clsp of a Pier one breast cancer candle boot to rise and fall and biases the blade with respect to the boot, which keeps the blade in contact with Woman...

What is it with this little country that makes them so good at speed skating? Speed skating as we know it has evolved from a way of transportation and leisure activity into a serious sport. This fast-track through history starts at the roughest days of the sport, to end at innovations that made everyone skate faster. The first Elfstedentocht marks the switch of ice skating into speed skating; with the first tours even allowing multiple winners at the same time. Invented in , this miles long tour on natural ice is feared as well as beloved. The length and setting of the course ask for extremely cold weather conditions; e. Innovations in gear, including insulating clothing, have made it safer to skate the tour since that year, with even the current king completing the tour incognito in In the first Olympic speed skating event was held. Patents in generic ice skating from were only 15, since then the sport has gone through an enormous growth. This decade marks the first big increase in patents, as shown in figure 1. Innovations throughout the 20 th century have had an amazing influence on the sport of ice skating. From better isolation till aerodynamic and neuromuscular advantages — speed skating is a sport greatly influenced by engineering. The golden medals earned by the Dutch in this sport might be due to a combination of a rich ice skating history, the popularity of the sport in this country and the home ground advantage of the clap skate invention. Bodil Oudshoorn is born in the Netherlands and did her undergraduate degree in Human Movements Sciences in Amsterdam at the same faculty that developed the clap skate in Next to speed skating she is, amongst others, interested and participating in snow sports, rugby, trail...

Modified to maintain high speed and control in turns. Short track blades are extremely sharp and are bent in at an arc that mirrors the direction of the turn. They are also placed off-center to the left so the boot does not touch the ice when the skater leans into the turn. Short track boots lace higher up the ankle than traditional skates and are constructed from fiberglass, graphite and Kevlar, using customized foot molds to help stabilize the foot and ankle around the corners. Socks are rarely worn. Short track speed skaters may touch the ice with their hands for stability in the turns, therefore their gloves have hard plastic balls on the fingertips to slide along the ice. A hard shell made of plastic to prevent potential head injuries resulting from crashes with competitors, ice or sidewalls. Fastens under the chin. Made of a synthetic material molded to the body shape. It is the same suit that long track speed skaters wear, but without the aerodynamic hood and thumb loops. Seven plastic markers are placed around the oval, setting the curve. Skating inside the markers results in disqualification.

Unlike in traditional skates where the blade is rigidly fixed to the boot, clap skates have the blade attached to the boot by a hinge at the front. This allows the blade to remain in contact with the ice longer, as the ankle can now be extended toward the end of the stroke, as well as for more natural movement, thereby distributing the energy of the leg more effectively and efficiently. Clap skates were developed at the Faculty of Human Movement Sciences of the Vrije Universiteit of Amsterdam , led by Gerrit Jan van Ingen Schenau , although the idea of a clap skate is much older; designs dating from around are known. It was, however, not until the late s that the idea was taken seriously. The rest of the skating world soon followed suit, causing a torrent of world records to be broken in the following seasons, including the Winter Olympics in Nagano , Japan. The idea of a hinging skate was described and patented in by Karl Hannes, from Raitenhaslach, Burghausen. For the season, 11 skaters from the South Holland 14—18 age category started using the clap skate competitively. Those 11 showed an average improvement of 6. Ten of them placed for the national championship. In the — season, the use of the clap skate caught on the highest level, and in Tonny de Jong was the first European all round champion using the clap skate, leaving Gunda Niemann , the defending world champion, in second place. Niemann remarked that the skate was illegal, and should be outlawed. The design was banned from use in short track speed skating. Research completed in showed that the speed gain from using the clap skate does not originate in using the calf muscle to stretch the ankle, as was assumed...

Both of this clap skate versions are known. Especially the ice skate version has become very popular. In the type of skate to which the invention relates, the skate frame has a forefoot support and a heel support. The forefoot support is pivotally connected to the frame about a transverse pivot pin. A forward tilting movement of the skater's foot relative to the skate frame, while the latter is in contact with the ice surface, is taking place against the action of a spring means. Thus said spring means tends to force the skate frame to return to its normal position relative to the skater's foot i. Thus the pivot connection between the frame and the forefoot support allows the skater's foot to turn away from the skate frame and thereby stretch completely during the skater's push being applied onto the ice surface. As a result of this the skater's push is optimalized. Depending on the angle, through which the skate frame has turned away during the push phase, the returning movement will take place with more or less force and consequently with a more or less powerful clap. It is a principle object of the invention to provide an effective and reliable spring means for effecting the return movement of the skate frame. A further object of the invention is to provide a compact spring means which is adapted to be mounted at a location where it is effectively guarded against access from the outside. Further objects and advantages of the invention will be hereinafter further explained by way of example with reference to the accompanying drawing. With reference to FIGS. A bracket 2 is fastened, e. A pivot pin 3 is fixedly, but removably connected between the two flanges 2 a of bracket 2 by means of a...
