This invention relates to trampolines. The invention has particular application to recreational trampolines of the type used in playgrounds and homes but it may have application to sporting trampolines as well. For many years recreational trampolines have typically included a tubular steel frame which is supported on spaced legs with a flexible jumping mat secured to the frame by a large number of spaced apart extension springs which extend and contract as a person jumps on the mat in order to give "bounce". The springs are usually connect the tubular steel frame at one end via radial slots provided therein and to the mat via hooks or the like at the other end. Although trampolines can be made in many shapes, circular is probably the most popular in which case the frame is generally constructed of arcuate segments of round tube which are joined together socket arrangement with the end portion of one into the end portion of the adjacent segment.
