Abstract
Abstract A dual-footboard scooter in a tricycle format, the front wheel of the scooter being coupled to a steering post passing through a steering column to join a steering handle provided with a hand brake operatively coupled to the front wheel. A pair of parallel footboards are attached at their front ends to a bifurcated frame extending rearwardly from the steering column. Secured to the underside of each footboard is a rear end wheel behind which is a skid brake adapted to engage the ground only when the footboard is upwardly tilted. In operating the scooter, the rider grasps the steering handle, one foot then resting on either one of the footboards, the other foot extending through the space between the footboards to make pushing contact with the ground to propel the scooter forward. Should the scooter jump in the course of travel and in doing so raise the front wheel above ground and cause the footboards to become upwardly inclined, the scooter then seeks to swing backward about the rear wheels and thereby endanger the rider. The action is avoided by the rear skid brakes which then engage the ground to cause the scooter to swing forward to return the front wheel to the ground.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
236 words
A foot-propelled dual footboard scooter in a tricycle format, said scooter comprising: A. a front wheel having an axle coupled by a fork to an upright steering post passing through a steering column to join a steering handle provided with a hand brake operatively coupled to the front wheel whereby a rider grasping the steering handle can steer and brake the scooter; B. a rigid frame extending rearwardly from the steering column; C. a pair of parallel footboards attached at their front ends to the frame to define a free space in front of and between the parallel footboards having a width sufficient to accommodate a foot of the rider to make pushing contact with a road surface to propel the scooter, the other foot of the rider resting on either of said footboards; and D. a rear end wheel mounted on the underside of each footboard whereby the scooter normally runs on three wheels, said frame extending from the steering column being bifurcated to define separate branches to which the front ends of the footboards are attached, said branches having a free space therebetween which merges with the free space between the parallel footboards to provide an extended free space whereby regardless of where the rider stands with one foot on either footboard, he is provided with an extended free space between the footboards in which to swing his other foot to propel the scooter.

Claim 4
Dependent Claim
27 words
A scooter as set forth in claim 2, in which the skid brake is formed of a synthetic plastic material having a high coefficient of sliding friction.
Claim 5
Dependent Claim
