Nava System
The Nava System was a ski binding and custom ski boot offered for sale in the 1980s. The system used a combination of flexible sole plate to keep the boot centered, and a spring-loaded plastic arm on the rear binding that was used to transmit sideways motions of the leg to the ski. This eliminated the need for a hard shell on the boot; the Nava boot was soft and resembled a knee-high winter boot. In spite of numerous endorsements by racing stars, the system never caught on and sales ended by the late 1980s. History The system was invented in the early 1970s by an Italian architect and skier, Antonio Faullin. He patented the design and sold the production rights in the mid-1970s. No production commenced, and the design was subsequently sold off to a number of manufacturers.Swett The design eventually found its way to Pier Luigi Nava, an avid skier whose company produced motorcycle helmets.

Ski Binding
A ski binding is a device that connects a ski boot to the ski. Before the 1933 invention of ski lifts, skiers went uphill and down and cross-country on the same gear. As ski lifts became more prevalent, skis—and their bindings—became increasingly specialized, differentiated between alpine (downhill) and Nordic ( cross-country, Telemark, and ski jumping) styles of skiing. Until the point of divergence in the mid-20th century, bindings held the toe of a flexible, leather boot against the ski and allowed the heel to rise off the ski, typically with a form of strap or cable around the heel. To address injuries resulting from falls while skiing downhill on such equipment, ski bindings emerged with the ability to release the toe of the boot sideways, in early models, and to release the boot forward and aft, in later models. Downhill ski bindings became standardized to fit plastic ski boots and incorporated a built-in brake that drags in the snow after the ski detaches from the boot. ...

Ski Boot
Ski boots are footwear used in skiing to provide a way to attach the skier to skis using ski bindings. The ski/boot/binding combination is used to effectively transmit control inputs from the skier's legs to the snow. History Ski boots were leather winter boots, held to the ski with leather straps. As skiing became more specialized, so too did ski boots, leading to the splitting of designs between those for alpine skiing and cross-country skiing. Modern skiing developed as an all-round sport with uphill, downhill and cross-country portions. The introduction of the cable binding started a parallel evolution of binding and boot. The binding looped a strap around the back of the boot to hold it forward into a metal cup at the toe. Boots with the sole extended rearward to produce a flange for the cable to firmly latch to become common, as did designs with semi-circular indentations on the heel for the same purpose. Effective cross-country skiing requires the boot to flex forward to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Motorcycle Helmet
A motorcycle helmet is a type of helmet used by motorcycle riders. Motorcycle helmets contribute to motorcycle safety by protecting the rider's head in the event of an impact. They reduce the risk of head injury by 69% and the risk of death by 42%. Their use is required by law in many countries. Motorcycle helmets consist of a polystyrene foam inner shell that absorbs the shock of an impact, and a protective plastic outer layer. Several variations exist, notably helmets that cover the chin area and helmets that do not. Some helmets provide additional conveniences, such as ventilation, face shields, sun visors, ear protection or intercom. Origins The origins of the crash helmet date back to the Brooklands race track in early 1914, when a medical officer, Dr. Eric Gardner, noticed he was seeing a motor cyclist with head injuries about every two weeks. He got a Mr. Moss of Bethnal Green to make canvas and shellac helmets stiff enough to stand a heavy blow and smooth enough to gla ...

Injection Moulding
Injection moulding (U.S. spelling: injection molding) is a manufacturing process for producing parts by injecting molten material into a mould, or mold. Injection moulding can be performed with a host of materials mainly including metals (for which the process is called die-casting), glasses, elastomers, confections, and most commonly thermoplastic and thermosetting polymers. Material for the part is fed into a heated barrel, mixed (using a helical screw), and injected into a mould cavity, where it cools and hardens to the configuration of the cavity. After a product is designed, usually by an industrial designer or an engineer, moulds are made by a mould-maker (or toolmaker) from metal, usually either steel or aluminium, and precision-machined to form the features of the desired part. Injection moulding is widely used for manufacturing a variety of parts, from the smallest components to entire body panels of cars. Advances in 3D printing technology, using photopolymers t ...
