Abstract
Abstract A foldable handle for skateboard includes a base plate adapted to be fixed on a base board of a skateboard; two opposed upright plates, fixed on the base plate and spaced apart from each other; a handle, pivoted between the upright plates, and which does not contact the base plate; a gripping mechanism for gripping releasably the handle, disposed between the upright plates along a side of the handle; and a block member, fixed between the upright plates along an opposite side of the handle from the gripping mechanism for blocking the handle; thereby, when the gripping mechanism is released, the handle is foldable to rest transversely on the base board of the skateboard from an operative position. Furthermore, the foldable handle can be used with the skateboard for exercise as soon as it is restored to the operative position.
