A swing is a seat, often found at playgrounds for children, at a circus for acrobats, or on a porch for relaxing, although they may also be items of indoor furniture, such as the Latin American hammock or the Indian oonjal. The seat of a swing may be suspended from chains or ropes. Once a swing is in motion, it continues to oscillate like a pendulum until external interference or drag brings it to a halt. Swing sets are very popular with children.
On playgrounds, several swings are often suspended from a shared metal or wooden frame, known as a swing set, allowing more than one child to play at a time. Such swings come in a variety of sizes and shapes. For infants and toddlers, swings with leg holes support the child in an upright position while a parent or sibling pushes the child to get a swinging motion. Some swing sets include play items other than swings, such as a rope ladder or sliding pole.
For older children, swings are sometimes made of a flexible canvas seat, of a rubberized ventilated tire tread, of plastic, or of wood. A common backyard sight is a wooden plank suspended on both sides by ropes from a tree branch.
Tire swings are a form of swing made from a whole tire. These are often simply a new or used tire hanging from a tree on a rope. On commercially-developed playground swing sets, oversized new tires are often reinforced with a circular metal bar to improve safety and are hung on chains from metal or wooden beams. They may hang vertically or hang flat, suspended from three or more points on one side. The flat version can hold three or more children. Pumping is achieved by using one or two of the three chains attached to the swing, and two (or more) children can pump in turn. [1]
Tire swings can also be used in spinners, where the occupants use their feet to propel the tire.
Natural swings may be created by lianas (creeper plants) in a subtropical wild forest like Aokigahara forest near Mount Fuji.
Rope swings are swings created by tying one end of a length of rope to a tree branch, bridge, or other elevated structure. A knot or loop is usually put on the other end to prevent fraying and help the swinger stay on. Rope swings are often situated so that those swinging on them can let go and land in water deep enough to cushion the fall and to be swum around in.
The incorporation of a shortboard such as a skateboard in which the rider stands is called swing boarding. It is made safer by the use of an attached board and a harness for the rider.
Baby swings are swings with a bucket shape with holes for the child's legs, or a half-bucket shape and a safety belt, that is intended to reduce the likelihood of a very young child from falling out.
Porch swings are swinging, bench-like seats, typically of painted wood and intended primarily for adults. The swing's suspension chains are permanently mounted to the porch ceiling; and the seat is typically large enough to seat about three people, with an armrest at each end. Porch swings are an alternative to using rocking chairs or gliders outdoors.
Canopy swings are similar to porch swings, but they are hung on a separate frame and are usually portable. The name is derived from a canopy installed as a sunshade.
Hammock swings are portable (removable) bed-swings made of a lightweight material such as canvas, netting (or as little as two ropes), typically suspended between two trees or attached to a hammock stand.
Tandem swings are swings designed for use by two people at the same time, facing each other or back-to-back, and are almost always part of a swing set due to the frame required to support the weights of the riders. The bench is perpendicular to its frame's center crossbar. Face-to-face tandem benches include a subframe with integrated handles and foot pegs. Back-to-back tandems are typically in the baby bucket design, but with two pairs of leg holes, one on each side of the bench. Tandem swings are typically suspended from their frame (as in kiiking) by steel bars, although ropes and chains may be used for those used only by smaller children. Face-to-face tandem swings were featured in the playground of the Columbia Gardens.
Nest swings resemble bird nests in shape and are able to carry multiple people. One or two people propel it by standing on the sides, grabbing the shackles that mount the basket to its typically wooden stand, and tilting it sideways. They are typically installed on playgrounds.
Swinging first spread throughout China during the Spring and Autumn period (771–476 BC). In the Han dynasty swinging continued to rise in popularity and was often performed at the Qingming Festival and the Duanwu Festival. By the time of the Song dynasty, swinging became involved in professional acrobatics, where performers would swing between boats over water. [2]
The earliest known representations of swings come from artifacts found in Greece. A terracotta sculpture of a woman sitting on a swing was found at Hagia Triada dated to the Late New Palace period (1450–1300 BC). [3]
In the 1700s, French artists depicted scenes of nobility swinging recreationally. [4]
Charles Wicksteed is thought to be the inventor of the modern-day swing. In 2013, one of his prototypes was unearthed near Wicksteed Park in the United Kingdom dating back to the early 1920s. [5]
In 1993, the sport of Kiiking was invented in Estonia. Players attempt to rotate 360 degrees around a spindle, on a long swing consisting of a seat hung with steel bars. [6]
In the early 1900s, the playground movement saw swings installed in public spaces for neighborhood children. By the middle of the century, the suburban playground became popular. Many Americans put personal swing sets on their property. Public concern for children's safety influenced a change in design after the 1970s. Tubular metal sets were replaced with smaller swings made of woods and resins better suited for children. [4]
The United States Patent and Trademark Office was disparaged in 2002 for issuing a patent [7] to a five-year-old boy who claimed to have invented swinging sideways as a new form of entertainment. [8] His father, a patent lawyer who wanted to show his son how the patent system worked, had told the boy that he could file a patent application on anything that he invented. The patent was rescinded upon re-examination. [9]
Swings can cause various types of injuries. [10] The most common injury is due to a fall, either by unintentionally letting go of the ropes or chains or by deliberately jumping out of the swing. [10] Less commonly, the person using the swing will bump into or kick another person who is walking by or playing too close to the swing, or (especially with improperly located home equipment) will bump into a fence, wall, or another fixed object. Swings are also associated with strangulation or hanging injuries, usually because the child was wearing a piece of clothing or other item that became entangled in the swing.
Swings are the most common cause of injury relating to playground equipment at private homes, but a much less common cause of injury in public or school playgrounds, where injuries from climbing equipment dominate. [10] Injuries from swings primarily affect school-age children, but preschool-age children also have a significant risk on swing sets at home. [10]
Swinging teaches full body coordination and improves the sensory system of a child. [11] It develops spatial awareness, gross and fine motor skills. It works out the entire body from pumping legs to grip strength. Swinging also helps teach the child rhythm and balance, and encourages social interaction as children must cooperate and play together. [11] In his 1885 poem, "The Swing," published in A Child's Garden of Verses, Robert Louis Stevenson exclaimed that going "up in a swing" was "the pleasantest thing/ Ever a child can do." [12]
A tandem bicycle or twin is a form of bicycle designed to be ridden by more than one person. The term tandem refers to the seating arrangement, not the number of riders. Patents related to tandem bicycles date from the mid 1880s. Tandems can reach higher speeds than the same riders on single bicycles, and tandem bicycle racing exists. As with bicycles for single riders, there are many variations that have been developed over the years.
Acrobatics is the performance of human feats of balance, agility, and motor coordination. Acrobatic skills are used in performing arts, sporting events, and martial arts. Extensive use of acrobatic skills are most often performed in acro dance, circus, gymnastics, and freerunning and to a lesser extent in other athletic activities including ballet, slacklining and diving. Although acrobatics is most commonly associated with human body performance, the term is used to describe other types of performance, such as aerobatics.
A trapeze is a short horizontal bar hung by ropes, metal straps, or chains, from a ceiling support. It is an aerial apparatus commonly found in circus performances. Trapeze acts may be static, spinning, swinging or flying, and may be performed solo, double, triple or as a group act.
A mooring is any permanent structure to which a seaborne vessel may be secured. Examples include quays, wharfs, jetties, piers, anchor buoys, and mooring buoys. A ship is secured to a mooring to forestall free movement of the ship on the water. An anchor mooring fixes a vessel's position relative to a point on the bottom of a waterway without connecting the vessel to shore. As a verb, mooring refers to the act of attaching a vessel to a mooring.
A hammock, from Spanish hamaca, borrowed from Taíno and Arawak hamaka, is a sling made of fabric, rope, or netting, suspended between two or more points, used for swinging, sleeping, or resting. It normally consists of one or more cloth panels, or a woven network of twine or thin rope stretched with ropes between two firm anchor points such as trees or posts. Hammocks were developed by native inhabitants of the Americas for sleeping, as well as the English. Later, they were used aboard ships by sailors to enable comfort and maximize available space, by explorers or soldiers travelling in wooded regions and eventually by parents in the early 1920s for containing babies just learning to crawl. Today they are popular around the world for relaxation; they are also used as a lightweight bed on camping trips. The hammock is often seen as a symbol of summer, leisure, relaxation and simple, easy living.
Sling furniture is usually a suspended, free-swinging chair, bed, or hammock that is made of a framework connected to hanging straps or rope. When attached to poles or a frame for carrying, a sling becomes a stretcher, a simple form of litter.
A dragline excavator is a heavy-duty excavator used in civil engineering and surface mining. It was invented in 1904, and presented an immediate challenge to the steam shovel and its diesel and electric powered descendant, the power shovel. Much more efficient than even the largest of the latter, it enjoyed a heyday in extreme size for most of the 20th century, first becoming challenged by more efficient rotary excavators in the 1950s, then superseded by them on the upper end from the 1970s on.
A jungle gym is a piece of playground equipment made of many pieces of material, such as metal pipes or ropes, on which participants can climb, hang, sit, and—in some configurations—slide. Monkey bars are a part of a jungle gym where a user, hanging in the air, swings between evenly spaced horizontal bars. In Australian English, the term "monkey bars" is sometimes used to refer to the entire jungle gym.
A derrick is a lifting device composed at minimum of one guyed mast, as in a gin pole, which may be articulated over a load by adjusting its guys. Most derricks have at least two components, either a guyed mast or self-supporting tower, and a boom hinged at its base to provide articulation, as in a stiffleg derrick. The most basic type of derrick is controlled by three or four lines connected to the top of the mast, which allow it to both move laterally and cant up and down. To lift a load, a separate line runs up and over the mast with a hook on its free end, as with a crane.
A ropes course is a challenging outdoor personal development and team building activity which usually consists of high elements, low elements, or some combination of the two. Low elements take place on the ground or above the ground. High elements are usually constructed in trees or made of utility poles and require a belay for safety.
A bench is a long seat on which multiple people may sit at the same time. Benches are typically made of wood, but may also be made of metal, stone, or synthetic materials. Many benches have back rests, while others do not and can be accessed from either side. Arm rests are another common feature. In many American public areas, benches may be donated by persons or associations, as indicated by an affixed plaque, a common form of memorial to a deceased person. Benches may be placed outdoors or indoors, but are more often found outdoors.
A power shovel, also known as a motor shovel, stripping shovel, front shovel, mining shovel or rope shovel, is a bucket-equipped machine usually powered by steam, diesel fuel, gasoline or electricity and used for digging and loading earth or fragmented rock and for mineral extraction. Power shovels are a type of rope/cable excavator, where the digging arm is controlled and powered by winches and steel ropes, rather than hydraulics like in the modern hydraulic excavators. Basic parts of a power shovel include the track system, cabin, cables, rack, stick, boom foot-pin, saddle block, boom, boom point sheaves and bucket. The size of bucket varies from 0.73 to 53 cubic meters.
Playground slides are found in parks, schools, playgrounds and backyards. The slide is an example of the simple machine known as the inclined plane, which makes moving objects up and down easier, or in this case more fun. The slide may be flat, or half cylindrical or tubular to prevent falls. Slides are usually constructed of plastic or metal and they have a smooth surface that is either straight or wavy. The user, typically a child, climbs to the top of the slide via a ladder or stairs and sits down on the top of the slide and slides down the chute.
An outdoor playset is a structure erected outside for children to play on and around.
A glider or platform rocker is a type of rocking chair that moves as a swing seat, where the entire frame consists of a seat attached to the base by means of a double-rocker four-bar linkage. The non-parallel suspension arms of the linkage cause the chair to simulate a rocking-chair motion as it swings back and forth.
Full circle ringing is a technique of ringing a tower bell such that it swings in a complete circle from mouth upwards to mouth upwards and then back again repetitively.
A Russian swing is a large, floor-mounted swing which is sometimes used in circus performances to make impressive high acrobatic jumps.
A playground, playpark, or play area is a place designed to provide an environment for children that facilitates play, typically outdoors. While a playground is usually designed for children, some are designed for other age groups, or people with disabilities. A playground might exclude children below a certain age.
Tarr Family Playground is a play area in New York City's Central Park at West 100th Street and Central Park West.
