<p>A cambering scooter is provided, of the type comprising a substantially upwardly extending main frame (12) having a pair of substantially horizontal twisting arms (16) extending rearwardly therefrom; a front wheel (14) attached to the said main frame (12) and a pair of rear wheels (17), each attached to one of said twisting arms (16) at their ends opposite to the main frame (12); a handle bar (13) associated to the said main frame (12) to allow an operator to rotate the same together with the front wheel (14) attached thereto about the longitudinal axis of the main frame, thus guiding the scooter; and a synchronizing mechanism (20, 40) for fixing the said twisting arms (16) to the main frame (12), so that the twisting arms (16) are free to pivot at least in one direction around their points of connection with the said main frame. This type of cambering scooter has the advantage that a great percentage of the force supplied by the operator is lost due to construction problems. The present invention obviated those problems by providing a scooter wherein the central axis (15) of the said front wheel (14) is located behind the longitudinal axis of the main frame (12), with regard to the length of the scooter; and the said handle bar (13) is located in a plane ahead of the main frame (12) with regard to the normal direction of movement of the scooter. An improved performance is obtained with the construction of the present invention. A synchronizing mechanism (20, 40) for a cambering scooter of this type is also provided by the present invention.</p> |
