Patent Application
20090075741
The present invention relates to extreme sports recreation and more particularly, promotion and recreating with inline boards.
Because of these five problems: newness, radical looks, long requisite riding distance, lack of initial stability, and risk of injury; learning to ride, and promoting inline boards is difficult. Some potential inline board users are intimidated by the newness and radical appearance of the boards. These characteristics invoke fear of injury which discourages all attempts to ride. Another problem is locating a long enough downhill riding distance. Traveling to a public location consumes time and fuel; furthermore, public locations are subject to distractions such as road traffic, pedestrians, noise, and weather. At trade show locations there is little or no room for demonstration. Inline board stability is impossible without adequate wheel velocity which is frequently attained only after numerous attempts by the user that results in board abandonments and discouragement. The final problem with inline boarding is that injury is inevitable. When board abandonment, at any velocity occurs, the result will be bumps and bruises for the rider and scratches on the expensive equipment at the very least.
Inline board promoters have used ramps to provide a starting point for learning to ride an inline board in various venues.
Ramps offer only limited control of forward velocity, causing high risk of injury to rider.
Ramps offer limited ride duration time, due to length of ramp and grade of role out area.
Ramps offer no aid in balance control.
Ramps cannot prevent accidental board roll out.
Ramps limit location choice due to large space requirement for set up.
It is there for an object of the invention to mechanically stimulate inherent gyroscopic stability of inline boards or other extreme sports vehicles by transmitting intelligent motor propulsion to the wheels of these vehicles.
It is an object of this invention to lessen accidental roll out of the inline board or other extreme sports vehicles by cradling the rear wheel or wheels between the rear rollers.
It is another object of the invention to improve extreme sports vehicle riding skills by allowing E.S.V.S.T riders to maintain very long riding time durations without dangerous distractions.
It is another object of the invention to improve the rider's health.
It is another object of the invention to promote inline boards or other extreme sports vehicles.
It is therefore an object of the invention to entertain.
In accordance with the present invention, there is provided through the use of intelligently motor propelled rollers and other important features,
a safe, fun, platform for riding mechanically stimulated inline boards or other extreme sports vehicles.
A complete understanding of the present invention may be obtained by reference to the accompanying drawings, when considered in conjunction with the subsequent, detailed description, in which:
For purposes of clarity and brevity, like elements and components will bear the same designations and numbering throughout the Figures.
This is a perspective drawing of the E.S.V.S.T. 10 mounted to a trailer for ease of transportation: The roller and motor frame 16 is constructed of rigid metal. This frame 16 supports the front roller 30, rear rollers 32, pulley and belt fenders 34 that cover roller pulleys 33, belts 35 and motor pulley 39 (
This is a perspective drawing of E.S.V.S.T. 10 with a extreme sports vehicle rider 60 riding a inline board extreme sports vehicle 8, while earth and sky video image 21 is being projected onto the three projection surfaces 24, 26, and 28. Not visible in any of the Figures, but included in this embodiment, is a small impact module affixed to the extreme sports vehicle 8. This module vibrates under the rider's feet when the rider's vehicle's path crosses or collides with debris and or obstructions shown in the earth and sky video image 21. Also, in this embodiment, the extreme sports vehicle 8 is equipped with no less than two signal switches routed through the power and signal wire harness 48. A contact switch beneath the rider's front foot engages roller motion when depressed by the riders front foot. This switch immediately disengages roller motion when the rider's front foot is removed by signals sent to the motor control 38. A second contact switch activated by the rider's engagement of the break lever on the extreme sports vehicle 8 signals the motor control 38 to coast the motor smoothly to decrease roller speed until the vehicle brake lever is disengaged.
This is a perspective drawing of the electric motor 40, front roller 30, motor pulley 39, rear rollers 32, front and rear roller pulleys 33, and the roller and motor frame 16.
This is a perspective drawing of the front rigid deck projection surface 26 swinging up to the vertical projection surface 24.
This is a perspective drawing detail showing the underside of a cut away deck section of an extreme sports vehicle 8 fastened by retainer 46 to the traveler car 44. The traveler car 44 is frictionlessly retained by the track 42.
This is a perspective drawing of E.S.V.S.T. 10 collapsed for transportation. The front rigid deck projection surface 26 is vertical to allow the front frame 14 to collapse inwards.
In a preferred construction, roller width is 72 inches with an approximate outside diameter of 5 inches, motor size is 2 horse power. Roller placement will be determined by the wheel base of the extreme sport vehicle to be used with the E.S.V.S.T. 10.
Those skilled in the art will readily appreciate that the present invention allows the user to practice extreme sports vehicle 8 riding skills in a fun safe controlled manner. Because the E.S.V.S.T. 10 rider and vehicle frame has no forward velocity the vehicle is prone to oversteer due to absent centrifugal force. To compensate for the absence of centrifugal force extreme sports vehicles used with E.S.V.S.T. 10 are to be fitted with steering dampeners to eliminate oversteer.
Since other modifications and changes varied to fit particular operating requirements and environments will be apparent to those skilled in the art, the invention is not considered limited to the example chosen for purposes of disclosure, and covers all changes and modifications which do not constitute departures from the true spirit and scope of this invention.
Having thus described the invention, what is desired to be protected by Letters Patent is presented in the subsequently appended claims.
