ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a riding assembly and more particularly to an all terrain riding assembly.
2. Description of the Prior Art
Rollerskates, rollerblades, skateboards, rollerskis and the like, as means for riding on even terrain such as a road surface have been widely known and used for some time. Skateboards, in particular, have become widely developed and generally comprise a platform large enough for a person to stand on with his or her feet side by side, and front wheel and rear wheel mounted for rotation about spaced apart parallel axes, the wheels being of rounded profile to enable the platform to tilt laterally in use. It is generally intended that the user should stand on the platform with his or her feet on either side of the imaginary line joining the centers of the wheels and should balance himself or herself as the skateboard moves forward.
In the copending application, U.S. Ser. No. 09/257,736, hereby incorporated by reference, there is disclosed an all-terrain riding assembly comprised of a body member having a supporting surface for feet of the user disposed between a front housing member having a spherically-shaped rotatably mounted roller member and a rear housing member having a rotatably mounted generally cylindrically-shaped roller member wherein the rear housing member is articulately mounted to the body member.
While such riding assembly is capable of being directionally controllable by the user by the shifting of weight, the riding assembly is subject to gravitational forces with concomitant potential injurious hazard to the user.
OBJECTS OF THE INVENTION
An object of the present invention is to provide an all terrain riding assembly having an assembly to control the linear velocity thereof.
Another object of the present invention is to provide an all terrain riding assembly of lighter weight.
Still another object of the present invention is to provide an all terrain riding assembly capable of more facile steering and maneuverability during use.
A still further object of the present invention is to provide an all terrain riding assembly having a tension assembly to provide a more stable riding platform under varying terrain conditions.
SUMMARY OF THE INVENTION
These and other objects of the present invention are achieved by an all terrain riding assembly comprised of a body member including a supporting surface for feet of the user disposed between a front housing member having a rotatably mounted roller member and a rear housing member having a rotatably mounted elongated roller member with a manually operated assembly to control the rotational speed of the elongated roller member and thus linear velocity of the riding assembly, as more fully hereinafter described.
