Inflatable castles (also called closed inflatable trampolines (CITs), bouncing castle, bouncy houses, bounce houses, jumping castle, bouncy castles, moon bounces, or moonwalks) are temporary inflatable structures and buildings and similar items that are rented for functions, school and church festivals and village fetes and used for recreational purposes, particularly for children. The growth in the use of such devices has led to a rental industry that includes inflatable slides, obstacle courses, and games. Inflatables are ideal for portable amusements because they are easy to transport and store.
Inflatables have been marketed under several names, such as "Bounce House", "Bouncies","Moon Bounce", "Boingalow", "Astrojump", "Moonwalk", "Jolly Jump" and "Spacewalk".
The first inflatable structure was designed in 1959 by John Scurlock in Shreveport, Louisiana who was experimenting with inflatable covers for a government request for proposal when he noticed his sons enjoyed jumping on the air structure. He was an electrical engineer and liked physics. Scurlock was a pioneer of inflatable domes, inflatable tents, inflatable signs and his greatest achievement was the invention of the safety air cushion that is used by fire and rescue departments to catch people jumping from buildings or heights.
The first space walk manufacturing company was in New Orleans in a leased warehouse that also sewed horse pads. His wife, Frances, started the first inflatable rental company in 1966 and in 1976 they built a custom facility for the production and rental of the products. They marketed the space walks to children's events such as birthday parties, school fairs and company picnics. These original inflatables did not have the enclosure of today's inflatables.
Their son Frank Scurlock expanded their rental concept throughout the United States under the brand names "Space Walk" and "Inflatable Zoo". Frank also opened an all inflatable indoor play park called "Fun Factory" 1986 in Metairie, Louisiana after visiting Nathan's Physical Whimsical in Englewood Colorado in 1982 & Nathan's Physical Whimsical in Houston Texas in 1984. Mr. Scurlock's Fun Factory copied a lot of the designs & play elements of (Houston's) Sharpstown Mall Physical Whimsical location, although no franchisee fees or design fees were paid to Nathan Elinoff. Nathan Elinoff is accredited with initiating the very first two indoor play parks concept in America. Mr. Scurlocks second location was opened in Memphis Tennessee called "Fun Plex" in 1987. Both locations closed after the value of the property became too great for the operations. The first inflatable was an open top mattress with no sides, called a "Space Pillow". In 1967 a pressurized inflatable top was added, it required two fans and got hot in the summer like a greenhouse. That version was called "Space Walk" and was adopted as the company name.
In 1974, to solve the heat problem, a new product line called "Jupiter Jump" was created that has inflated columns that supported netting walls which allowed the air to pass through. Further enhancements of this style were developed such as a line of castles and animals which are referred to as the "Inflatable Zoo". In the early 1990s, Frank created the first commercial inflatable water slide called the "Aqua Tunnel". Space Walk was the first company to bring an inflatable to the IAAPA convention, Showmen's Club and the American Rental Association.
The other story which has not been written about is the actual creation of the Moonwalk. This was designed and invented by the Regehr family in the 1960's. It was after that the Scurlock family said it was there creation back in the 1959 which cannot be documented. This simply is not true. Vern and Bob Regehr were years ahead of the other family and have been recognized as such many times over. The families fortune was derived from this invention. They also were the family that designed the many themed moonwalks over the decades such as Spiderman or Waterslides. With the help of Randall Paul in Michigan, the idea to market these for children parties brought this business to another level. Thanks to Randall and his ingenious marketing strategies to bring this into the homes at an affordable price parties for kids are just not the same without a moonwalk!.
The surfaces are typically composed of thick, strong PVC or vinyl and nylon, and the castle is inflated using an electric or petrol-powered blower. The principle is one of constant leakage, meaning small punctures are not a problem - a medium-size "bouncy castle" requires a fan with a mechanical output of about two horsepower (about 1.5 kW) and consumes around 2 kW of electrical power, allowing for the efficiency of the motor.
UK and Australian bouncy castles have specifications calling for fully inflated walls on three sides with an open front and foam "crash mats" to catch children who may jump or fall out of the structure.
Modern moonwalks in the US are typically supported by inflatable columns and enclosed with netting. The netting allows for supervision as adults can see in from all sides.
Another type of home-use inflatable has evolved, with a blower pumping in air continuously. Pores in the seams and material allow air to escape as children play, while the blower continues to inflate the unit. This category has emerged as a response to parents who wish to buy an inflatable for home use.
In 2005, the most severe standards in the construction of an inflatable amusement were adopted nationally in Australia, forming Federal Standard AS3533.4. This was a landmark safety standard bringing the toughest design/construction/operation standards to the inflatable industry of Australia. In 2006 the European Union (EU) followed and introduced similar standards throughout EU called EN14960:2006 which was then updated in 2013 to EN14960:2013.
In the US, Pennsylvania and New Jersey require inflatables to pass engineering and safety standards before allowing the equipment to be rented out. North Carolina requires amusements rides, including inflatables, to be inspected annually by the North Carolina Department of Labor (NCDOL). For inflatables to pass inspection, operators in North Carolina are required to have all training records, a current certificate of insurance, and device manuals. Inflatables that are damaged and not safe will not pass inspection until they are repaired.
Inflatable obstacle courses
There are also inflatable obstacle courses that allow for participants to have races/sword fights and compete against one another. These are commonly rectangular in shape, but can also be square if the course is maze-like. Most obstacle courses have two lanes, but some can have three or four. They feature various such as pop-up obstacles, climbing areas, slides, and tunnels. These are the best choice for very large events since participants move through them quickly.
Some inflatables are designed to allow games such as boxing rings, water football, penalty shootouts, basketball, rumbling, tug of war, and gladiator duels. These interactive inflatable games are made out of the same material that a continuous airflow bounce house is made of. Quad tracks are also popular and provide the perimeter for Quad bike racing.
Injury and death
According to U.S. studies published in the journal Pediatrics in 2012, injuries caused by inflatable rides have been on the rise in the United States. In 2010, "as many as 31 U.S. children per day were treated for injuries sustained in a bounce house, or one child every 46 minutes". That is an estimated 65,000 children under the age of 17 that have been injured from 1990 to 2010. From 2000-2015, there were 64 bounce house accidents in the United States caused by wind, resulting in 271 injuries and 10 deaths.
In May 2001, the U.S. Consumer Product Safety Commission released a bulletin outlining the dangers and recommended safety precautions for operating an inflatable structure. In 2015, after studying the incidents of injury the Consumer Product Safety Commission released a revised bulletin for the recommended safety precautions for operating an inflatable device.
