The present invention relates to skateboards, and more particularly to skateboards that are foldable.
Skateboards have been known for years and typically consist of a generally flat board with upturn front and back ends, and a pair of wheels mounted adjacent each of the front and back ends. A rider places one foot on the skateboard and propels himself along by pushing with the other foot on the ground. Once a rider has reached a desired speed, both feet are placed on the skateboard in a spaced apart stance. Skateboards are typically about perhaps two feet long by eight to ten inches wide so as to be large enough to readily accommodate a rider's feet in a spaced apart stance.
While it is common for skateboard riders to use skateboard recreationally, it is also common for them to use skateboards for travelling to nearby locations. However, due to the size of a typical skateboard, many skateboarders do not skateboard to places such as school, the mall, and so on, since it is necessary to either carry the skateboard around for a long period of time or to store the skateboard somewhere.
What is needed is a compact foldable skateboard that is easy to carry around, such as in a backpack, and is easy to store.
U.S. Pat. No. 5,224,719 issued Jul. 6, 1993 to Goodspeed, discloses a Skateboard. This skateboard has a pedal mounted on top of the front end of the deck. The front wheels are powered through a pulley mechanism by the pedal. However, the deck itself is not foldable.
U.S. Pat. No. 6,158,751 issued Dec. 12, 2002 to Wu et al, discloses a Skating Board Folding Structure. This unit is actually closer to a scooter than a skateboard, and the front wheel and the handle stem are pivotally mounted onto the board portion at a pivot at the front of the board.
A folding skateboard is unknown in the prior art.
It is an object of the present invention to provide a foldable skateboard.
It is another object of the present invention to provide a foldable skateboard that can readily be carried in a backpack.
It is a further object of the present invention to provide a folding skateboard that is compact when folded.
It is a further object of the present invention to provide a folding skateboard that is easy to fold between its straight in-use configuration and its folded carrying configuration.
In accordance with one aspect of the present invention there is disclosed a novel compact foldable skateboard comprises a central board portion having a top surface, a bottom surface, a left side edge, a right side edge, a front edge and a rear edge, and defining a longitudinal axis extending between the front edge and the rear edge. A front board portion has a top surface, a bottom surface, a left side edge, a right side edge, a front edge and a rear edge. The front board portion and the central board portion are connected one to the other in rear edge to front edge relation, by a front hinge means, for longitudinal folding movement with respect to each other between a flat in-use configuration whereat the front board portion and the central board portion are vertically and horizontally aligned one with the other, and a folded storage configuration whereat the front board portion and the central board portion face each other. A selectively operable front locking means is mounted on one of the front board portion and the central board portion for releasably locking the front board portion and the central board portion in the flat in-use configuration. A front wheel carriage is mounted on one of the front board portion and the central board portion. A rear board portion has a top surface, a bottom surface, a left side edge, a right side edge, a front edge and a rear edge. The rear board portion and the central board portion are connected one to the other in front edge to rear edge relation, by a rear hinge means, for longitudinal folding movement with respect to each other between a flat in-use configuration whereat the rear board portion and the central board portion are vertically and horizontally aligned one with the other, and a folded storage configuration whereat the rear board portion and the central board portion face each other. A selectively operable rear locking means is mounted on one of the rear board portion and the central board portion for releasably locking the rear board portion and the central board portion in the flat in-use configuration. A rear wheel carriage is mounted on one of the rear board portion and the central board portion.
