ABSTRACT:
FIELD OF THE INVENTION
The invention relates to an adult two-wheel vehicle adapted for acrobatic use, particularly in the descent of steep inclines. More particularly this invention relates to a scooter-like vehicle for use in aggressive downhill off-road riding and the performance of acrobatic tricks and maneuvers while in rolling and/or sliding engagement with the ground and ground-supported objects or airborne.
BACKGROUND OF THE INVENTION
The two-wheel scooter has long been regarded as a child's toy, and while there have been various attempts made to improve the use of a scooter as a toy, for example, by combining the scooter and snow sled by the addition of runners which may be retractable, scooter-like vehicles have not been considered a source of adult entertainment or adapted for acrobatic use and the performance of tricks in the manner of bicycles, skateboards, motorcycles and other wheeled vehicles. The following U.S. patents relate to scooters and scooter-like vehicles in various suggested modifications: U.S. Pat. Nos. DES. 292,221; 4,991,861; 4,842,091; 4,123,079; 4,087,106; 3,179,433; 2,486,689; 2,319,066; 1,844,305; 1,706,048; 1,701,410; 1,689,916; 1,617,337; 1,591,581 and 1,516,015.
BRIEF STATEMENT OF THE INVENTION
This invention provides a two-wheel vehicle adapted for use by acrobatic adults by using not only the wheels, but a snag-free, omni-directional sliding surface, under a large standing area, which may be maneuvered by a rider into engagement with the ground and ground-supported objects to perform a variety of tricks and displays of acrobatic skill. Such an adult vehicle comprises a first means for providing a steerable front wheel that is free to rotate about a first axis of rotation carried by the first means; a second means connected with and supported by the first means, forming a spacious upper platform for carrying both feet of a standing rider in a variety of positions and locations and further forming a lower surface for omni-directional sliding engagement with the ground and ground-supported objects; and a third means connected with and supporting the second means and carrying a rear wheel rotatable about a second axis of rotation. In such an adult vehicle, the upper platform is supported by the first means and the third wheel means below the first and second axes of rotation but a few inches above the ground, and has, for example, a width of about 10 to 12 inches and a length of about 24 to 27 inches, to assist an acrobatic rider in displaying his abilities by performing a variety of tricks and feats of acrobatic skill. The lower surface of the second means preferably provides a snag-free, generally smooth and lubricous, surface with an upwardly slopping ramp-like front surface and snag-free, smooth lubricous side surfaces for multi-directional sliding engagement with the ground and ground-supported objects.
Vehicles of the invention are preferably provided with relatively large diameter wheels that roll easily on uneven, soft and turfed ground and can be “jumped” by an acrobatic rider onto and over ground-supported objects without bringing the vehicle to an abrupt stop.
Preferably, such wheels can be provided with air-filled and knob-treaded tires for engagement with the ground and reduced slippage and for providing pneumatic cushioning for the rider, particularly, when the vehicle is directed in the contact with ground-supported objects. The first means will include a handlebar permitting the rider to ride and control the vehicle and it is preferable that the handlebar be provided with brake actuators to independently operate brakes for the front and rear wheels.
Such a vehicle is particularly adapted for operation on steep inclines and hills and provides a rider the ability to control and direct his descent and to enjoy speed, and the ability to veer the vehicle rapidly, the ability to become airborne off of ground dislocations, the ability to slidably engage the ground and ground-supported objects such as logs, concrete curbs, and the ability to perform tricks while sliding or airborne in a manner similar to skilled riders of skateboards and skis.
Other features of this invention will be apparent from the drawing and the further and more detailed description of the invention that follows.
