Trampoline system with systematically phased spring elements

a spring element and trampoline technology, applied in trampolines, gymnastic exercise, sport apparatus, etc., can solve the problems of large number of injuries suffered during an impact with the rebounding surface, devices that do not directly address injuries, and injuries that are still occurring on the floor, so as to reduce the quantity and severity of on-bed injuries.

Problems solved by technology

However, thousands of injuries have resulted when persons jumping on a trampoline have landed on the rebounding surface while in an awkward or incorrect body position.
However, these devices do not directly address injuries that result when users impact the rebounding surface incorrectly or while in an awkward position.
However, such harnesses are designed for safely teaching users advanced acrobatics on high-performance competition trampolines by trained professionals, making them largely inappropriate for low-performance backyard trampolines that are used almost entirely for basic jumping activities and not for advanced acrobatics.
Nevertheless injuries suffered during an impact w

Embodiment Construction

[0010] A system that embodies a new use for adjustable or extendable springs is provided. Completely counter to using adjustable or extendable springs to equalize the tension between all the springs as conceived by the prior systems, the present system uses adjustable springs to systematically vary the tension between the springs. For example, removing most of the tension on every other spring (half of the total number of springs) while they are at rest makes the bed safer by changing its rebounding dynamics.

[0011] All things being equal, varying the spring tension this way is more effective than the prior art at preventing on-bed injuries that result from multiple jumpers and awkward landings. For instance, many injuries occur when multiple users are jumping asynchronously, a first jumper deflects the bed and loads springs with the energy from his fall and now a second jumper lands on the bed in an awkward position. At this point in time, the bed is highly tensioned (unforgiving) ...

Abstract

Springs or other elastic connectors used to support a bed within the frame of a trampoline or the like are attached using methods that systematically vary the tension (or the travel distance required to reach limit of elasticity) between adjacent (or sets of adjacent) springs. These spring attachment methods increase the time it takes a given trampoline to absorb a given amount of energy, increasing the shock absorption time and thereby reducing the likelihood of an injury.

Description

[0001] This is a continuation of application Ser. No. 10 / 110,884, filed Apr. 15, 2002, which is the National Stage of International Application No. PCT / US01 / 25544, filed Aug. 14, 2001, which claims the benefit of Provisional Application No. 60 / 225,135, filed Aug. 14, 2000, which applications are incorporated herein by reference.BACKGROUND AND SUMMARY [0002] The present invention concerns jumping surfaces used with trampolines to protect trampoline users from injury, and to provide new uses for trampolines. In the past, trampolines have been used for a variety of athletic and recreational purposes. However, thousands of injuries have resulted when persons jumping on a trampoline have landed on the rebounding surface while in an awkward or incorrect body position. These “on-bed” injuries, according to some medical studies, represent the majority of trampoline-related emergency room visits. The U.S. Consumer Products Safety Commission (CPSC) reports that in 1999 approximately 110,000 p...
