Abstract
A motorized skateboard or skateboard-like vehicle including a deck upon which the user can stand, fore and aft skateboard-like trucks and a drive wheel mounted intermediate the fore and aft trucks. A suspension allows a range of travel above the drive wheel relative to the deck. In one aspect, a biasing means biases the drive wheel away from the deck.
Claims29
A vehicle comprising:
- (a) a skateboard comprising (i) a platform defining generally a first plane and (ii) front and rear trucks, each truck comprising at least one rotatable wheel, the bottom of the wheels of the trucks generally defining a second plane spaced apart from and below the first plane;
- (b) a drive wheel mounted to the skateboard by an arm, the arm having one portion mounted to the skateboard and extending to an end to which the drive wheel is rotatably mounted, the drive wheel having a diameter this is at least on the order of the distance between the first and second planes;
- (c) an opening in the platform generally aligned with a third plane which is generally orthogonal to the first and second planes, the opening between the first and second trucks and adapted to allow passage of at least a portion of the drive wheel;
- (d) a biasing member connected between the skateboard and the arm to bias the arm and the drive wheel away from the skateboard but allowing a range of travel generally in the third plane towards and away from the skateboard, the range of travel comprising a first position wherein a portion of the drive wheel passes into the opening in the platform and the bottom of the drive wheel is above the second plane and nearer the first plane, to a second position wherein the drive wheel is substantially or completely below the opening and the bottom of the drive wheel is below the second plane;
- (e) a motor operatively connected to rotate the drive wheel.

A motorized vehicle comprising:
- (a) a skateboard comprising a platform with a deck for standing generally defining a first plane, and a pair of trucks at opposite ends, each truck comprising at least one rotatable wheel, the bottom of the wheels of the trucks generally defining a second plane spaced apart from and below the first plane;
- (b) a drive wheel positioned intermediate said trucks and suspended relative to the platform, the drive wheel having a diameter this at least on the order of the distance between the first and second planes;
- (c) an opening in the platform generally aligned with a third plane which is generally orthogonal to the first and second planes, the opening between the first and second trucks and adapted to allow passage of at least a portion of the drive wheel;
- (d) a suspension supporting the drive wheel, but allowing a range of movement of the drive wheel between a position towards and a position away from the platforms. the range of movement comprising a first position wherein a portion of the drive wheel passes into the opening in the platform and the bottom of the drive wheel is above the second plane and nearer the first plane to a second position wherein the drive wheel is substantially or completely below the opening and the bottom of the drive wheel is below the second plane.

A motorized skateboard comprising:
- (a) a deck generally defining a first plane, front and rear trucks mourned to the deck, each truck comprising at least one rotatable wheel, the bottom of the wheels of the trucks generally defining a second plane spaced apart from and below the first plane;
- (b) a suspension operatively mounted to deck;
- (c) a drive wheel operatively mounted in the suspension, the drive wheel having a diameter this is at least on the order of the distance between the first and second planes;
- (d) an opening in the platform generally aligned with a third plane which is generally orthogonal to the first and second planes, the opening between the first and second trucks and adapted to allow passage of at least a portion of the drive wheel;
- (e) the suspension allowing a range of movement of the wheel relative to the deck, the range of movement comprising a first position wherein a portion of the drive wheel passes into the opening in the platform and the bottom of the drive wheel is above the second plane and nearer the first plane, to a second position wherein the drive wheel is below the second plane;
- and
- (f) a motor operatively connected to the drive wheel.
