Pair of wheeled skate-skis usable on most terrains

Abstract

A pair of wheeled skate-skis comprising a chassis with two upwardly projecting forked ends, a flexible foot strap attached to a front side of the chassis, a front buckle slide fastened to an opposite front side of the chassis, two buckle slides, an adjustable binding, a front wheel assembly and a rear wheel assembly. To secure a shoe in position, the flexible foot strap is wound around the shoe and through the front and rear buckle slides and folded back to be fixed to itself by a hook-and-loop fastener. The upwardly projecting forked ends of the chassis have a plurality of axle-receiving holes for mounting wheels of various sizes and types. The chassis can be made by injection molding or compression molding or by cutting a section of fiberglass I-beam.

         5 . A pair of wheeled skate-skis for use on most terrains, as claimed in  claim 4 , wherein the fasteners of the outer shell of the adjustable binding are each a ratchet buckle and a strap. 
     
     
         6 . A pair of wheeled skate-skis for use on most terrains, as claimed in  claim 4 , wherein the fastener of the two overlapping portions of the inner liner of the adjustable binding is a hook-and-loop fastener. 
     
     
         7 . A pair of wheeled skate-skis for use on most terrains, as claimed in  claim 4 , wherein
 the outer shell of the adjustable binding has two overlapping portions; and   the fasteners of the outer shell of the adjustable binding are fastened over the two overlapping portions of the outer shell,   wherein one or more pairs of guide flanges are disposed on one of the overlapping portions for guiding and receiving the other overlapping portion in order to keep the two overlapping portions in alignment with each other when the wheeled skate-ski is in use.   
     
     
         8 . A pair of wheeled skate-skis for use on most terrains, as claimed in  claim 4 , wherein the two bottom portions of the adjustable binding and the two rear buckle slides of each wheeled skate-ski are fastened together at the respective side of the chassis. 
     
     
         9 . A pair of wheeled skate-skis for use on most terrains, as claimed in  claim 3 , wherein the angle between the substantially straight line of the axle-receiving holes and the foot-receiving body portion of the chassis is between 40° and 50°. 
     
     
         10 . A pair of wheeled skate-skis for use on most terrains, as claimed in  claim 3 , wherein the end of the flexible foot strap fastened to the first side of the chassis is inclined at an angle from a vertical line to the foot-receiving body portion of the chassis. 
     
     
         11 . A pair of wheeled skate-skis for use on most terrains, as claimed in  claim 10 , wherein the angle between the end of the flexible foot strap fastened to the first side of the chassis and a vertical line to the foot-receiving body portion of the chassis is between 10° and 20°.
