Abstract
An improvement to the sporting apparatus known as the snowboard. The hoverboard applies air cushioned technology to snowboards. The Hoverboard contains a powersourse, an airblower and a sport board platform modified to maintain an air cushion. The structure of the board is designed so that the board glides on a cushion of air. As a result the speed and maneuverability of the snowboarder is significantly increased.
Description
~ 21 ~7678 The present invention applies air cushioned technology to a sport board. Although this combination is intended for the recreational snowboard; the broad term sport board is used. The snowboard is a recreational sporting equipment and the hovercraft is an air cushioned vehicle; therefore the hoverboard is the name given to this invention.
The basic snowboard is a rectangular structure of usually one inch semi-flexible material. Presently, a significant portion of commercial o snowboards are constructed out of fiber reinforced plastic. The r mning surface is usually flat. The result of such a large contact area is that there are relatively high frictional losses, thereby reducing the speed of the snowboarder. The flat surface also limits quick transitions in the direction of the snowboarder.
The hoverboard rides on a cushion of air thereby significantly reducing the contact friction; thereby significantly increasing the speed of the snowboarder (or hoverboarder). The contoured bottom surface of the hoverboard helps to allow the board to ride on top of the snow and 20 because of the air cushion, instability is increase, thereby increasing the maneuverability. This hybrid ma~cimi7es the speed and maneuverability as applied to snowboarding applications.
There are many dirrere,lt types of air cushioned technologies such as: open plenum, peripheral jet, flexible skirt, fixed wall and ACV pallet systems. This hybrid utilizes the peripheral jet system with some modifications. The peripheral jet system was chosen since the augmentation factor is roughly 50 percent greater (depending on the configuration) than a similar configuration of an open plenum system.
30 The augmentation factor in it's simplest form is the ratio of the cushion force to lift force. This difference in augmentation ratio between the open plenum and peripheral jet tr~n.~l~tes into roughly 30 percent less power to generate simil~r lift characteristics.
The design parameters ofthe peripheral jet system are in accordance to the "exponential theory". The design equations used for the m~ f~cture of the hoverboard are as follows:

The above equations are used to optimize the design. The design parameters of the hoverboard such as: orientation and geometry of the nozzles, r mning surface, air intake orifice, air cavities, peripheral skirt and other elements of the hoverboard are based on the exponential theory, fluid mechanics and structural mechanics.
21a~678 -The present invention consists of an air cushioned apparatus for increasing the speed and maneuverability of a sport board. In one aspect of the invention, the apparal~ls comprises of a modified upper board, a powersource, a blower driven by the powersource, and a contoured bottom surface. The upper board platform is modified to accommodate the peripheral structures such as: the adjustable foot bin~lin~, tracks for the foot bindings, an air intake manifold, an air intake orifice, fuel storage area and an inner cavity whereby the blower draws air in from the intake manifold directing it into the inner cavity. A frame is used to 10 mount the power source and blower above the intake orifice and is stre~mlined to the airflow.
The tracks are c-shaped, forming a T~slot inhrn~l cavity. There is one pair of tracks for each foot and the tracks run parallel and are mounted longit~l(lin~lly on the modified upper board platform. One track is located at the toe end of the foot binding and the other track is located at the heel end of the foot bintling A pair of T-sliders, translate along the tracks and are fixed at the slots on the bindings. The adjustable bin~linp;~
formed by a pedal contoured plate with a longitutlin~l slot located at the toe and heel. A pair of straps mounts the foot to the plate. The foot 20 orientation is m~int~ined, by adjustable locking fasteners that fix the T-sliders into the slots and into the tracks.
The air intake manifold has a protective intake to stop the entry of foreign objects. There is an orifice that leads to an inner cavity. A
plurality of nozzles connect the inner cavity to the contoured bottom surface. The blower is mounted over the orifice and has a geometry to maximize the air flow. In some variations of the invention the blower 30 can be driven by electrical derivatives such as: battery, hydrogen power cells and solar electric.
In this aspect the blower is driven by an intern~l combustion power source. In this aspect the small hobbyist intern~l combustion type engine drives the blower. There is a small crank used to start the engine and a knob for controlling the power. The exhaust is vented into the 21 ~7678 -inner cavity. In this aspect the fuel is contained in a tough container located on the modified upper sport board.
The blower is connected to the power source. There are many types of apparatuses used to pressurize air, such as: the axle flow turboblower, propeller turbines, air coml"essors and radial flow turboblower. The hoverboard may use any type of blower system to generate the air cushion. The radial flow blower system may be more effective but, in this aspect, for simplicity, the propeller turbine system is used.
o In this aspect, the air cushioned device uses a contoured bottom surface which consists of: a concave elliptical surface between the hoverboard and the ground. The nozzles are connected to the inner cavity. The blower directs air from the air intake manifold into the inner cavity through the intake orifice. The air follows an arcuate path as it accelerated through the nozzles. The semi-rigid skirt along the periphery of the hoverboard limits air leakage. The nozzles array and inner cavity are of a geometry, orientation and distribution to m~imi7:e the augmentation factor in the peripheral jet air cushioned system.
The invention as exemplified by the preferred embodiments, is described with refelcllce to the drawings in which:

Referring to the drawings, the embodiment of the invention as shown in Figure 1 includes: a hoverboard 10 which comprises of an upper board platform 11, a powersource 12 and blower 14 driven by the powersource. The powersouce and blower are nested inside the air intake manifold 16; which mounts on the upper platform. The blower and powersource mounts on top of the air intake orifice 20. The blower takes air from the manifold and directs it into the inner cavity 18, through o the intake orifice. The air cushion is then generated by the distribution of nozzles 34, as seen in Figure 1 and Figure 3. The nozzles connect the inner cavity to the contoured bottom surface 30.
The contoured bottom 30 of the hoverboard, as seen in Figure 3, forms a concave surface 31 between the ground and the bottom of the board. The greater the hydraulic area of this concave surface the greater the efficiency of the air cushion. The concave surface forms into the rails. The rails are formed along the longit~l~lin~l bottom edge 38 and 20 the rails meet the ground at acute angles 36; as seen in ~igure 4. A
peripheral skirt 40, mounts to the longit~ldin~l edges of the board, extending below the bottom surface, helping to m~int~in the air cushion by limiting air leakage.
The feet mount to adjustable bin-lin~ 22, located on the upper platform 11; as seen in Figure 1 and Figure 2. There are two pairs of c-tracks one for each foot, one located at the toe of the foot 26 and the other located at the heel 28. The bindings mount to the tracks through locking T-sliders 27. There are longit~din~l slots on the bindin~ near 30 the toe and heel, 23 and 25 respectively. The foot orientation is adjusted through the horizontal tr~n~l~tion of the T-slider along the track which is linked to the longit~ldin~l slots on the foot binding~; a locking f~tçnçr is part of the slider and is used to fix the foot orientation.
Although only one embodiments of the present invention has been described and illustrated, the present invention is not limited to the features of this embodiment, but include all variations and modifications within the scope of the claims.
