Abstract: A pivot mechanism includes a base member configured to be coupled to a first element and a generally cylindrical rotating member configured to be coupled to a second element. An elongate pin extends through the base member and rotating member and defines a pivot axis. The rotating member is capable of rotating relative to the base member about the pivot axis. The elongate pin is movable in a direction generally parallel to the pivot axis between a secured position and a release position. In the secured position, the rotating member is prevented from rotating relative to the base member, and in the release position, the rotating member is permitted to rotate relative to the base member. The pivot mechanism may be incorporated into a scooter or a tricycle to provide different configurations thereof.

Abstract: A movable vehicle includes a first frame member, a second frame member, and a biasing mechanism. The first frame member includes a front wheel and a handlebar configured to turn the front wheel in various directions. The second frame member has at least one rear wheel and is coupled to the first frame member such that the first frame member can rotate with respect to the second frame member. The biasing mechanism is operatively coupled to the first and second frame members and biases the front wheel in a preferred direction, such as a straight direction. The biasing mechanism may include a resilient gasket and a cavity having at least partially corresponding polygonal cross sections.

Abstract: A pedal includes a pedal body configured for engagement with a person and defining a first major side and a second major side of the pedal. A first plate member engages the first major side and has a first outer surface. Similarly, a second plate member engages the second major side and has a second outer surface. At least one of the first or second outer surfaces includes a graphic design feature. The first and second plate members may be coupled to each other through openings in the pedal body. The graphic design feature may be carried on a graphic design element which is coupled to the first and/or second outer surface.
