Today, the vast majority of tires are pneumatic inflatable structures, comprising a doughnut-shaped body of cords and wires encased in rubber and generally filled with compressed air to form an inflatable cushion. Before rubber was invented, the first versions of tires were simply bands of metal that fitted around wooden wheels in order to prevent wear and tear. The tread provides traction while the body ensures support. The fundamental materials of modern tires are synthetic rubber, natural rubber, fabric and wire, along with other compound chemicals. The word itself may be derived from the word "tie," which refers to the outer steel ring part of a wooden cart wheel that ties the wood segments together (see Etymology below). Other terms for inflatable boats are "inflatable dinghy", "rubber dinghy", "inflatable", "inflatable rescue boat" or " rubber duck".Ī tire (in American English and Canadian English) or tyre (in British English, New Zealand English, Australian English and others) is a ring-shaped covering that fits around a wheel rim to protect it and enable better vehicle performance by providing a flexible cushion that absorbs shock while keeping the wheel in close contact with the ground. This feature allows such boats to be used as liferafts for larger boats or aircraft, and for travel or recreational purposes. Here the boat when inflated is kept rigid crossways by a foldable removable thwart. Some inflatable boats have been designed to be disassembled and packed into a small volume, so they can easily be stored and transported to water when needed. Often the transom is rigid, providing a location and structure for mounting an outboard motor. On boats longer than 3 metres or 10 feet, the floor often consists of three to five rigid plywood or aluminium sheets fixed between the tubes but not joined rigidly together. For smaller boats, the floor and hull beneath it is often flexible. As a whole the term moon bounce has become a generic term for enclosed inflatable trampolines worldwide even though some still cling to the less popular hipster form "Bounce House."Īn inflatable boat is a lightweight boat constructed with its sides and bow made of flexible tubes containing pressurised gas. Bouncy Castle or Inflatable Castle are used in Ireland, the UK, New Zealand and parts of Australia, and Jumping Castles in Arizona, Australia, Canada and South Africa. In Southern California, another popular term is Closed Inflatable Trampolines, or "CITs". In the United States the terms that consist of two, one syllable words are popular. Historically, names for inflatable structures, particularly in the United States, are composed of two, one syllable words. Because of liability concerns, moonwalks are rarely rented to adults in the US. The term 'Jolly Jumps' is often used to describe the inflatable playground structure in rural areas and some areas in the Western US, but the term is otherwise obsolete.Īlthough they are often aimed at children, adult castles can be hired in the UK. The term "Bounce House" came to popularity with the resurgence of hipster culture in New England. They have been marketed with such names as Bounce house, Moon Bounce, Astrojump, Moonwalk, Jolly Jump, Leaping Lodge and Spacewalk. The name given to such structures varies. Inflatables are ideal for portable amusements because they are easy to transport and store. The growth in popularity of moonwalks has led to an inflatable rental industry which includes inflatable slides, obstacle courses, games, and more. Inflatable castles and similar structures are temporary inflatable buildings and structures that are rented for functions, school and church festivals and village fetes and used for recreational purposes, mainly by children.
