Because it is too hot to walk outside except at 6 a.m., I have been walking on the second-story track at the Addison Athletic Club which overlooks the basketball court. Today is the start of summer camp for kids, so an enormous bounce house has been set up. I watched a guy set up the last part of it. I assume this one guy set up the entire thing. The deflated slide piece was all rolled up and tied to a dolly. The slightly built guy wearing Crocs struggled to tip the bundle forward off the dolly. It was unwieldy and much bigger than he was, but he managed and started unrolling it until it was spread out to half the size of the basketball court. Then he proceeded to hook up the powerful blower that inflated it. Afterwards, he attached a pile of heavy weights all around the bounce house to keep it anchored in place. Outside, I guess it might blow away, but inside I assume all the bouncing might turn it on its side if not anchored. It was quite a process. I marveled at the technology that makes kids’ dreams come true. I imagined some engineer/designer sitting up late at night trying to figure out how to make it work. American ingenuity is alive and well. Let’s learn more about bounce houses.
According to Wikipedia, inflatable bounce houses — also called closed inflatable trampolines or CITs, inflatable castles, bouncing castles, bouncy houses, jumping castle, jumper, 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."
Inflatable bounce houses have been suggested as having some therapeutic value for children with certain sensory impairments, similar to ball pits.
History
One claim for invention goes to John Scurlock in 1958. Scurlock was a plastics specialist who taught at Tulane University and worked for NASA, and who also later invented the Space Walk safety air cushion, which is used by fire brigades responding to high-rise fires and stunt performers. According to his family, he was inspired in the late 1950s while designing inflatable tent covers for tennis courts. In 1958 he also founded Space Walk Inc. The family business ran an indoor amusement park in the 1980s, The Fun Factory, in Metairie, Louisiana, but transitioned to and today continues to rent heavy-duty inflatables for occasions ranging from county fairs to children's birthday parties. The idea to rent inflatables for parties is attributed to Scurlock's wife Frances, who was running a business by 1969.
According to the article “History of the Bounce House” at buffalobouncehouserental.com, John Scurlock was a mechanical engineer and liked physics. The first Space Walk manufacturing company was in New Orleans in a leased warehouse that also sewed horse pads. In 1976 the Scurlocks 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, creating a safety hazard.
Their son Frank Scurlock expanded the rental concept throughout the United States under the brand names Space Walk and Inflatable Zoo. He also founded the first all inflatable indoor play park called Fun Factory on Thanksgiving Day 1986 in Metairie, Louisiana. A second unit 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 had 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 Scurlock created the first commercial inflatable water slide called the Aqua Tunnel. Space Walk Inc. was the first company to bring an inflatable to the International Association of Amusement Parks and Attractions convention, Showmen's Club and the American Rental Association.
According to Wikipedia, Bob Regehr is also credited for inventing the bouncy house in 1968, under the brand name Moon Walk.
As part of the space-themed toy trend sparked by the space race, “The Moon Walk,” a closed inflatable trampoline with a plastic roof designed for children's safety, was available for mail order in the 1975 Neiman Marcus catalog.
The original bouncy house was essentially an air pillow with a roof, but the hundreds of modern models include inflatable waterslides, basketball gyms, a game in which players attempt to knock each other over with a large inflatable wrecking ball and characters licensed from multimedia franchises such as Frozen. Thousands of companies now rent inflatable bounce houses in the United States. The market has also diversified to include lighter retail designs. By 2014, the industry was estimated to be worth $100 million.
The world's largest inflatable bounce house, The Big Bounce America, was certified in 2018 at 11,433.99 square feet. It included multiple zones, such as ball pits, a slide, inflatable forests, a basketball court and a DJ booth. It was designed as an inflatable theme park for all ages and toured the United States in the summer of 2019 as a traveling festival.
With adult play a growing trend, bounce house rentals have also seen increased popularity at weddings.
Inflatable bouncy houses, slides, pools and other large outdoor toys for retail home use became more popular in the summer of 2020 due to the COVID-19 pandemic, providing a means for parents to entertain their children while maintaining social distancing. With schools and day care facilities closed, parents bought inflatables to occupy their children while working from home.
Construction
The surfaces are typically composed of thick, strong PVC or vinyl and nylon, and the bounce house is inflated using an electric or gasoline-powered blower. The principle is one of constant leakage, meaning small punctures are not a problem. A medium-size bounce house requires a fan with a mechanical output of about two horsepower or 1.5 kW and consumes around 2 kW of electrical power, allowing for the efficiency of the motor.
UK and Australian bounce houses 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 U.S. 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.
Standards
In 2005, the most stringent 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 followed and introduced similar standards throughout EU called EN14960:2006 which was then updated in 2013 to EN14960:2013.
While bounce house manufacturers adhere to voluntary standards, no national safety standards exist in the U.S., although some states such as Pennsylvania and New Jersey require that inflatables pass engineering and safety standards before allowing the equipment to be rented out. In 2017, roughly 25 U.S. states had regulations governing permits, inspections and insurance, although a private investigation by the Pew Charitable Trust has shown significant shortcomings by industry operators and regulators to do their part. North Carolina requires amusements rides, including inflatables, to be inspected annually by the North Carolina Department of Labor. 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 have various features 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.
Games
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
Injuries are common. According to Jim Barber, spokesman for the National Association of Amusement Ride Safety Officials, "It happens all the time. These are probably the most dangerous amusement devices they have. You see more injuries on inflatables than almost any other amusement ride you can think of — more than roller coasters." 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." An estimated 65,000 children under the age of 17 were injured from 1990 to 2010.
Injuries caused by inflatable rides were rising in the United States, according to a 2012 study published in the journal “Pediatrics,” which found a 15-fold increase from 1995 to 2010, a trend corroborated in the 2003–2012 period by a 2015 U.S. Consumer Product Safety Commission report.
Frank Scurlock, son of inventor John Scurlock and manager of bouncy inflatable rental company Space Walk, ascribes the increase to rising non-commercial use of inexpensive retail “backyard” units, while bounce houses have also become more common overall. The rising number of injuries related to inflatable amusements is small however in absolute terms when compared to the more everyday hazards of playgrounds and skateboards, which respectively were linked to an estimated 270,000 and 114,000 injuries in 2012.
In a survey spanning 2003–2013, the most common injuries were fractures, strains, sprains, dislocations, contusions, abrasions and lacerations. An estimated 88% of the injured were less than 15 years old. Most injuries occur due to falls or collisions with another child. Some severe fall injuries occur after wind lifts bouncy castles skyward. From 2000 to early 2016, there were 64 bounce house accidents worldwide 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 commission released a revised bulletin for the recommended safety precautions for operating an inflatable device.
