ABSTRACT:
A skateboard with an elongated platform having a tail section and a main body section coupled together by an angularly adjustable joint that holds the sections in a preselected angular relation and permits adjustment of the tail section to various angles relative to the plane of the body section. In one embodiment, the adjustable joint is an elongated plate having front and rear end sections secured to the body and tail sections, respectively, of the skateboard platform, and, extending between the front and rear sections, an intermediate section that is bendable to a preselected angle, but has sufficient strength and stiffness to resist bending under the normal forces exerted on the tail section during tilting of the skateboard. In an alternative embodiment, the adustable joint is an elongated plate with front and rear sections, with the front section being secured to the body section of the platform and the rear section being covered with a pliable nonslip plastic or rubber material to form the tail section of the platform, so that the tail section itself can be curved as well as angularly adjusted relative to the body section. In another alternative embodiment, the angularly adjustable joint is a hinge with front and rear hinge elements secured to the body and tail sections, respectively, of the skateboard platform, and connected together by a pivot pin. The pin has a threaded end engageable with a nut for locking the tail section in its preselected angular position by placing the hinge elements in compressive engagement.
