Abstract
Abstract This device is an improved wheelie skateboard having a substantially flat horizontal portion and an integrally connected inclined rear kicktail portion. The front end of the horizontal portion has a pair of conventional skateboard wheels on a truck having a pivot bolt connected to the axle at the rear of the axle, and capable of swivelling in a conventional manner. The inclined kicktail portion has a pair of conventional skateboard wheels having a pivot bolt forward of the axle and, likewise, capable of swivelling in a normal manner. The central pair of wheels is so mounted as to be incapable of swivelling, either because of the nut on the pivot bolt (of a conventional truck), which is to the rear of the axle, is so tightened, or because a horizontal arm portion on a non-conventional truck extends from the truck rearwardly of the axle to forwardly thereof, so that such pair of wheels may tilt but may not swivel.

Claim 1
Independent Claim
276 words
A wheelie skateboard (10) comprising an elongated platform for supporting a person, the platform having a forward end section (14), a longitudinal center line section (16) and a rear end section (18) in approximately the same plane with said forward and center line sections, and an inclined kicktail section (22) extending integrally upwardly and rearwardly from said platform end section (18) and merging (20) smoothly therewith, a first pair of wheels (24) and a common axle (26) coupled to and positioned on a forward truck (32) secured beneath said platform forward end section (14), a second pair of wheels and a common axle therefor coupled to and positioned on an intermediate truck (44 or 48) secured beneath said platform (12) rearward end section (18), and a third pair of wheels and a common axle therefor coupled to and positioned beneath a kicktail truck 46 secured to said kicktail section (22), all said axles being mounted on said trucks, said axle for said first pair of wheels having a truck pivot bolt (42) rearward of its said axle, said axle for said third pair of wheels on said kicktail section having a truck pivot bolt forward of its said axle, and said second pair of wheels having its axle mounted forward of its pivot bolt, and means substantially preventing said axle of said second pair of wheels from swivelling about its pivot bolt, whereby a person positioned on said platform forward of said kicktail section may ride supported on said first and second pair of wheels, or, positioned partly on said kicktail section, may ride on said skateboard supported on said second and third pairs of wheels.
Claim 2
Dependent Claim
