Quad roller skate

Abstract

This is a description of a quad roller skate for use on outdoor surfaces, including a traditional roller skate boot with a stiff sole, with the sole bottom, and the heel bottom being in general alignment with an imaginary horizontal plane. The sole and boot of the skate have opposed side edges with the wheels being positioned in vertical planes spaced from the opposed side edges. The wheels of the quad skate are of such diameter that each wheel apex is at least as high as the imaginary horizontal plane. The wheels can have larger diameters with the apexes being higher than the horizontal plane. A support plate is secured to the sole bottom and the heel bottom. Double action forward and rearward trucks with front and rear axles are mounted to the support plate. The skate has thin lightweight wheels having profiles defining a semicircular surface.
