<p>A skate board vehicle comprising a platform for supporting the user of the vehicle, and including front and rear wheel-and-axle supports in which at least one of the wheel-and-axle support includes a supporting bearing block reciprocatingly supporting a slide element carrying a pivot pin pivotally mounting a steerable axle-and-wheels, the pivot pin having mounted thereon an axlesupport sandwiched between a pair of resilient elements, and a brake assembly incorporating a hairpin-spring type element having braking arms normally urged onto the outer circumference of a pair of spaced wheels, and a coil spring interposed between the slide and an abutment projecting from the undersurface of the skate board vehicle platform, so that the skate board vehicle has shock-absorbing characteristics, is steerable, and the brake Assembly is weight-responsive so that when a user's weight is imposed on the platform of the skate board vehicle, the brake is released and the skate board vehicle is used in a conventional manner, but when the skate board is used on a relatively steep slope, for example, and a user falls off or steps off, the wheels of the skate board will automatically be braked.</p> |
