秋千 swing
A swing is a hanging seat,usually found in a playground for children,a circus for acrobats,or on a porch for relaxing.The seat of a swing can be attached to a chain or a rope.Once a swing is in motion it continues to oscillate like a pendulum until external interference or drag brings it to a halt.
On playgrounds,several swings are often suspended from the same 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 rubberized ventilated tire tread,of plastic,or of wood.A common backyard sight is of a wooden plank suspended on both sides by ropes from a tree branch.Older children can go much higher,sometimes over 15 feet (5 m) above the ground.
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 swingsets,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 of more points on one side.These flat type of swings 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.Tire swings can also be used in spinners,where the occupants use their feet to propel the tire.Children find ways of performing dangerous stunts on tire swings,and because of this,many have been removed from schools and parks.[citation needed]
Natural swings may be created by lianas (creeper plant) in a subtropical wild forest like Aokigahara forest near Mount Fuji.
A Rope swing is a makeshift swing created by tying a length of rope to a tree branch.Rope swings are often located on branches that overhang a river or lake for added excitement.
Belt Swing:Made of strong,thick and durable polymer,and UV-protected to be fade resistant,most belt swings are safety tested for strength and durability.Most manufacturer's use stainless steel clamps with "teeth" applied with over 2000 lbs.of pressure to secure the rope at the point where it attaches to the swing belt.Some manufacturers use a heavy-grade wire wrap to hold the rope,which could come loose or scratch your child.
Infant Swing:A double-sided infant bucket swing is perfect for the little ones; and safe and convenient for parents.Recommended for children 6 months to 3 years of age.
Full Bucket Swings usually have a 360 degree design which completely envelops the child for maximum security and safety.Most manufacturer recommend a full bucket swing for toddlers under the age of 3.
Toddler Swing:Allows a toddler the ability to get in and out of their own swing.This transition swing adds stability with a back support.
