Truck assemblies for skateboards

A skateboard comprising:

• a deck;
• a pair of track assemblies secured to the underside of the deck, each truck assembly comprising a main body mounted to the underside of the deck;
• an axle supporting a pair of spaced wheels, said axle having a longitudinal axis;
• a mount mounting the axle to the main body, said mount comprising a pivot permitting pivotal movement of the axle in a first plane to effect steering of the skateboard, the axis of pivotal movement of said axle lying in a second plane extending substantially longitudinally of and normal to a plane of the deck;
• said pivot including a pair of pivot members extending on opposite sides of said axle and rotatably engaged with an adjustable support body rotatably mounted to the main body for movement about an axis extending substantially normal to a longitudinal axis of the skateboard and parallel to the deck of the skateboard, the axis of rotation of the support body and said longitudinal axis of said axle being substantially co-linear when said axle is in a non-pivoted position extending substantially parallel to the plane of the deck of the skateboard;
• and
• means for selectively adjusting the rotational position of the body to adjust the axis of pivotal movement of the axle in the second plane and thereby the plane of pivotal movement of the axle to enable variation of steering characteristics of the skateboard.

A truck assembly for use with a skateboard, the truck assembly comprising

• a main body adapted to be mounted to the underside of a deck of the skateboard;
• an axle for supporting a pair of spaced wheels, said axle having a longitudinal axis;
• a mount for a mounting the axle to the main body, said mount comprising a pivot permitting pivotal movement of the axle in a first plane to effect steering of the skateboard, the axis of pivotal movement of said axle lying in a second plane extending substantially longitudinally of and normal to a plane of the deck of the skateboard;
• said pivot including a pair of pivot members extending on opposite sides of said axle and rotatably engaged with an adjustable support body rotatably mounted to the main body for movement about an axis extending substantially normal to a longitudinal axis of the skateboard and parallel to the deck of the skateboard, and
• an adjustment arm for selectively adjusting the rotational position of the support body to adjust the axis of pivotal movement of the axle in said second plane and thereby the plane of pivotal movement of the axle to enable variation of steering characteristics of the skateboard, said adjustment arm being fixed for movement with said support body and a locator for locating the adjustment arm in a selected one of a plurality of fixed positions.
