trampoline

Description ...

A trampoline is an elevated, essentially buoyant webbed bed or canvas sheet supported by springs or elastic shock cords. It is surrounded by a metal frame and used as a springboard for tumbling. The trampoline is used in the sport of trampolining (sometimes called rebound tumbling). In the sport, the trampoline is used to rebound the athlete, so he or she can perform acrobatic movements in midair. The trampoline is also a training tool for gymnasts, divers, and pole vaulters. Tumbling and acrobatic moves have existed for centuries. Humans have tried to get in the air in many ways. One of the first ways was the springboard. The springboard allowed the performer to leap high with little effort and do acrobatic stunts. Another device used to get airborne was called "the leaps." It was made of a resilient, rather narrow wood plank supported at both ends by blocks that kept the plank off the floor. Court jesters in the Middle Ages jumped on it when they performed at court. Circus lore has it that a Frenchman, named du Trampoline, helped develop the basics of the trampoline as we know it. For years, circus performers had used a net under the trapeze so they could rebound. By developing a system of spring suspensions, the Frenchman, a former trapeze artist, moved trampoline development forward. He adapted safety nets and experimented with spring suspension systems to make the earliest form of the trampoline. Trampolines are made of four basic components: the tubing, springs, jumping mat, and safety pads. The tubing, used to make the frame and legs of the trampoline, is usually made of galvanized steel and is bought at a certain length and width from a supplier. Using galvanized steel protects the frame from rust and environmental conditions as many home trampolines are for outside use. The springs, which give the trampoline its bounce, are commonly made to the specifications of the trampoline company by another supplier. Usually, the company making the springs specializes in spring manufacture. The jumping mats are made of woven fibers. Today, mats are made of artificial fibers like polyethylene or nylon. The heavily woven fabric is WV-protected to prevent fading when used out of doors. Safety pads go over the springs and frame and are made of foam. They have vinyl covers and pie straps to connect the pads to the frame. The manufacture of the foam core of the safety pads is also outsourced and made to manufacturer specifications.
