Abstract
A sports conveyance is disclosed having a frame mounted on a pair of spaced front wheels and also supported by rear wheel means, the front wheels having interconnecting means whereby they may be turned in unison to either side of the longitudinal center line of the conveyance, a board mounted on the frame to support a rider and adapted to be depressed at a respective side of the longitudinal center line of the conveyance, said board being adapted to be disposed in a substantially horizontal position with the front wheels unturned but so connected to the interconnecting means of the front wheels that depression of the board by body weight of the rider at a respective side of the board causes turning of the wheels in unison in the respective direction upon movement of the board.
Claims7
A sports conveyance comprising:
- a substantially flat, elongate, rider-supporting board having spaced longitudinal side edges extending between front and rear ends of the board;
- frame means connected to the board in such manner that the board is tiltable about a longitudinal tilt axis, the board being symmetrical to either side of the tilt axis so that the longitudinal side edges of the board are at equal distances on opposite sides of the tilt axis;
- said frame means including a rear frame section supported by rear wheel means permitting motion of the board in the direction along said tilt axis;
- said frame means including a forward frame section supported by a pair of steerable front wheels disposed at equal distances on opposite sides of the board and spaced from the longitudinal side edges of the board;
- said front wheels having respective stub axles in respective wheel mountings arranged to permit rotation of the front wheels about axes transverse to said longitudinal tilt axis;
- interconnecting means between the front wheels whereby they may be turned in unison to either side of the direction along said tilt axis;
- the board being adapted to be disposed in either an untilted substantially horizontal disposition in which the front wheels permit motion of the conveyance in the direction along the tilt axis or in a selected tilted disposition, the board being so connected to the said interconnecting means of the front wheels that depression of the board by body weight of the rider at a respective side of the board causes turning of the front wheels in unison for steering in the corresponding direction;
- said front wheels having their wheel mountings connected by said forward frame section which extends transversely beneath the board rearwardly of the front end of the board, said forward frame section having said tilt axis midway along its length, while to each side of said tilt axis the forward frame section is of a shape defining a depression or bowed portion at a lower height than the tilt axis to accommodate a respective side edge of the board when the latter is tilted to the maximum extent at the respective side of the tilt axis.
