Penny Board
A Penny board is a type of skateboard that is characterised by a short and narrow plastic deck. Although such skateboards were first manufactured during the 1970s, their name and contemporary popularity comes from the Australian brand Penny Skateboards, founded in 2010. The company's name has since been widely genericised to describe all small plastic skateboards. History The first line of plastic skateboards was launched in the 1970s by Larry Stevenson for his Makaha brand. Grentec also began to manufacture plastic skateboards.Courtney RubinPenny Skateboards Find a Niche ''Nytimes.com'', 22 July 2015 These plastic skateboards were widely popular during the early 1970s, although the era's professional skaters still shunned them in favour of wooden boards. By 1978, laminated wooden decks had become the industry standard. Ben Mackay created the Penny board in 2010, from which the brand Penny Skateboards was born. McKay named the brand for his sister, Penny. The idea behind th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Skateboard
A skateboard is a type of sports equipment used for skateboarding. They are usually made of a specially designed 7-8 ply maple plywood deck and polyurethane wheels attached to the underside by a pair of skateboarding trucks. The skateboarder moves by pushing with one foot while the other foot remains balanced on the board, or by pumping one's legs in structures such as a bowl or half pipe. A skateboard can also be used by simply standing on the deck while on a downward slope and allowing gravity to propel the board and rider. If the rider's leading foot is their right foot, they are said to ride "goofy". The two main types of skateboards are the longboard and the shortboard. The shape of the board is also important: the skateboard must be concaved to perform tricks. History Skateboarding started in California in the 1950s. The first skateboards were made from roller skates attached to a board. Skateboarding gained in popularity because of surfing: in fact, skateboarding ...

Generic Trademark
A generic trademark, also known as a genericized trademark or proprietary eponym, is a trademark or brand name that, because of its popularity or significance, has become the generic term for, or synonymous with, a general class of products or services, usually against the intentions of the trademark's owner. A trademark is said to become ''genericized''—or, informally, to have suffered ''genericide''—when it begins as a distinctive product identifier but changes in meaning to become generic. This typically happens when the products or services which the trademark is associated with have acquired substantial market dominance or mind share, such that the primary meaning of the genericized trademark becomes the product or service itself rather than an indication of source for the product or service. A trademark thus popularised has its legal protection at risk in some countries such as the United States and United Kingdom, as its intellectual property rights in the trademark ...

Larry Stevenson
Richard Lawrence "Larry" Stevenson (December 22, 1930 – March 25, 2012) was the inventor of the kicktail, the bent-upwards end of a skateboard, which made most of today's skateboarding tricks possible and essentially revolutionized the sport. Early life Stevenson was born in 1930 in Los Angeles, California; his mother was Inez Kiem and his father was Leonard Stevenson. After high school Larry Stevenson joined the U.S. Navy as a fighter mechanic. He served for two years in the Korean War. After that, he went on to Santa Monica College in California and became a swimmer. He played water polo and swam for Coach John Josephs. Stevenson won the all American award for fastest time for the breast stroke. The record was only recently broken, and he was given a lifetime allowance into any Santa Monica College event, if he wished to attend. After SMC, Stevenson went to USC, on a swimming scholarship, where he majored in business. During the middle to late part of the 1950s, St ...

Barefoot
Barefoot is the state of not wearing any footwear. There are health benefits and some risks associated with going barefoot. Shoes, while they offer protection, can limit the flexibility, strength, and mobility of the foot and can lead to higher incidences of flexible flat foot, bunions, hammer toe, and Morton's neuroma. Walking and running barefoot results in a more natural gait, allowing for a more rocking motion of the foot, eliminating the hard heel strike and generating less collision force in the foot and lower leg. There are many sports that are performed barefoot, most notably gymnastics and martial arts, but also beach volleyball, swimming, barefoot running, barefoot hiking, and water skiing. Certain situations can however determine people to be barefoot against their will mainly for reasons of precaution, identification or punishment. Historical and religious aspects Athletes in the Ancient Olympic Games participated barefoot and generally unclothed. The Ro ...

Polyurethane
Polyurethane (; often abbreviated PUR and PU) refers to a class of polymers composed of organic chemistry, organic units joined by carbamate (urethane) links. In contrast to other common polymers such as polyethylene and polystyrene, polyurethane is produced from a wide range of starting materials. This chemical variety produces polyurethanes with different chemical structures leading to many List of polyurethane applications, different applications. These include rigid and flexible foams, varnishes and coatings, adhesives, Potting (electronics), electrical potting compounds, and fibers such as spandex and Polyurethane laminate, PUL. Foams are the largest application accounting for 67% of all polyurethane produced in 2016. A polyurethane is typically produced by reacting an isocyanate with a polyol. Since a polyurethane contains two types of monomers, which polymerize one after the other, they are classed as Copolymer#Alternating copolymers, alternating copolymers. Both the isocy ...

Plastic
Plastics are a wide range of synthetic or semi-synthetic materials that use polymers as a main ingredient. Their plasticity makes it possible for plastics to be moulded, extruded or pressed into solid objects of various shapes. This adaptability, plus a wide range of other properties, such as being lightweight, durable, flexible, and inexpensive to produce, has led to its widespread use. Plastics typically are made through human industrial systems. Most modern plastics are derived from fossil fuel-based chemicals like natural gas or petroleum; however, recent industrial methods use variants made from renewable materials, such as corn or cotton derivatives. 9.2 billion tonnes of plastic are estimated to have been made between 1950 and 2017. More than half this plastic has been produced since 2004. In 2020, 400 million tonnes of plastic were produced. If global trends on plastic demand continue, it is estimated that by 2050 annual global plastic production will reach over 1, ...
