Abstract
Abstract A slide is provided with a simplified support construction involving a reduced number of parts at reduced cost. Also, the appearance of the slide is improved by placing a substantial portion of the reduced support directly under the slide path. Each slide path may include only four vertical supports with the slide supported on those supports with only four cantilevered brackets. The brackets hold four girder segments extending end-to-end directly under the slide path.
