Definitions

  • the invention relates to a wheeled vehicle, and more particularly to a scooter.
  • Scooters have been in existence for a long time, but have been designed and engineered largely for use by children on paved or smooth, relatively flat surfaces.
  • the word "scooter” usually describes a two or three wheeled vehicle having a steerable front wheel and a platform extending between the front and rear wheels on which one or both feet of the rider may be placed as the device is ridden. Scooters are commonly propelled by the rider pushing with one foot.
  • most prior scooters have had wheels of small diameter and width, and little or nothing in the way of braking and suspension systems.
  • a fundamental object of such scooter structures is effective low speed travel on paved or smooth, relatively flat surfaces.
  • mountain bikes attempts to solve the problem of providing a wheeled vehicle capable of negotiating rough "off road” terrain, including downhill slopes, with sufficient speed, safety, and finesse to have recreational appeal. Although such mountain bicycles are much better than normal bicycles for descending rough terrain, they still cannot travel safely over terrain as rough as much of that found on many hills and ski slopes.
  • a scooter which includes a front wheel supporting member, such as a fork; a front wheel assembly rotably mounted on the front wheel supporting member; a steering shaft extending from the front wheel supporting member; a steering pivot in which the steering shaft is pivotally mounted; a rear wheel supporting member, such as a fork; a rear wheel assembly rotably mounted on the rear wheel supporting member; a platform having a surface for supporting a user's foot; and structural members supporting the platform from the steering pivot and the rear wheel supporting member.
  • both the front and rear wheel assemblies include pneumatic tires that are greater than 5 inches in width, greater than 14 inches in outside diameter, and have more than four inches between their inside and outside diameters.
  • the scooter includes a brake, such as a powerful, lockable disk, drum, or band brake on at least the rear wheel assembly.
  • the steering shaft extends through the steering pivot at an angle which is at least twenty degrees off vertical when the scooter is standing upright on a horizontal surface to give the scooter greater steerability when going down hills, and that a suspension system be mounted between the steering pivot and the location on the front wheel supporting member where the front wheel assembly is rotably mounted.
  • the handlebars can be mounted on a shock absorber.
  • a majority of the weight of the scooter, excluding its tires, is comprised of lightweight materials.
  • the scooter's body is formed of a monocoque body, such as one formed of molded lightweight material. Such lightweight construction makes the scooter easier to handle and transport and safer to use. To further increase safety, some embodiments place padding on some of the surfaces which face a rider.
  • the platform which supports a rider's feet be at or below the level of the front and rear axles.
  • the bottom of the platform be at least at least four inches off the ground.
  • fenders can be placed over the wheels, and to enable the rider to rest during certain portions of his or her ride, a seat, preferably a low one, can be placed over the rear wheel. It is also preferred that the scooter have handlebars, the height of which can be adjusted, preferably by hand, for different height riders and different type slopes.
  • the scooter is relatively large, having a wheel base of at least forty-two inches, since it is intended for adult use, although smaller versions can be made for children.
  • the idea of making a gravity driven scooter for adults may sound silly.
  • a bicycle provides much more control than a scooter, and would be the preferred vehicle for descending steep hills and mountains.
  • the scooter of the present invention has many advantages when used for descending hills and mountains, and particularly ski slopes.
  • the feet that the scooter's rider stands on a relatively low platform — rather than sitting on a relatively high seat, straddling a metal frame, with feet on peddles — means the rider has much more freedom of movement. It gives the rider much more freedom to keep his center of balance low and back, decreasing the chance that the scooter or its rider will fall forward when hitting a large bump. It makes it easy for the user to absorb the bumps by bending at the knee, as in skiing, rather than receiving them through a seat. It makes it much easier for the rider to lean his weight from side to side in turning, and to use his or her feet as an outrigger to stay upright in sliding turns. It also makes it very easy for the user to quickly jump off the scooter when it is about to fall or hit something.
  • the device for descending hills and mountains disclosed in this application is a scooter, rather than a motor powered vehicle, such as a motor cycle, motor scooter, or all-terrain vehicle. This makes it lighter, easier to handle and control, and more safe. It also makes it less polluting, less noisy, and more aesthetically pleasing. Since the major intended use of the scooter is on ski slopes, motorized power is not necessary because the scooter and rider can be taken to the top of a ski slope by a chair lift or gondola.

  • FIG. 11 is a rear view of the steering shaft in an alternate embodiment of the invention showing a hand-operable mechanism for allowing the rider to adjust the height of the top of the steering shaft, upon which the handlebar is mounted;
  • FIG. 12 is a cross-sectional view of the hand-operable mechanism shown in FIG. 11, taken along the lines 12-12 shown in FIG. 11.
  • a scooter 30 which forms one preferred embodiment of the present invention is shown.
  • Its front and rear tires 32 and 34, respectively, are lightweight pneumatic tubeless tires with a knobby tread, with an outside diameter of twenty inches, a sidewall width of six inches, and an inside, or bead, diameter of eight inches.
  • Other embodiments of the invention preferably use lightweight tires, with outside diameters greater than fourteen inches, sidewall width greater than five inches, and a difference between the outside diameter and inside diameter being at least four inches.
  • the rear tire will have a relatively smooth tread, so that when the rear tire is slid around in a sliding turn, it will dig up the terrain less.
  • the rear tire may have larger tread on its upper side edges, so that the scooter will have reasonable traction in normal turns, when the scooter is tilted to one side but the rear tire is not purposely slid to one side.
  • the pressure in the tires should be low enough to maximize the tires' shock absorbing capabilities.
  • the air pressure in the tires is typically low enough that the centers of the front and rear axles 44 and 46 are approximately nine and a half inches off the ground, rather than approximately ten inches, as they would be if the twenty inch tires 32 and 34 were fully inflated.
  • the front and rear wheel rims 36 and 38, respectively, of scooter 30 are eight inches in diameter and six inches in width, and are made of spun aluminum.
  • Other embodiments of the invention can use other lightweight rims, such as ones made of other types of aluminum, of titanium, or of a metal or carbon fiber matrix composite, with dimensions to accommodate the particular tires with which they are used.
  • the front and rear hubs 40 and 42, respectively, of the scooter are made of cast aluminum, with standard bearings. Other embodiments of the present invention use hubs made of other lightweight metals or of a metal or carbon fiber matrix composite.
  • the front and rear axles 44 and 46, respectively, are made of steel or aluminum. In other embodiments the rim and hub could be made as one unit.
  • the front wheel assembly formed of the tire 32, rim 36, and hub 40 is rotably mounted on the front axle 44 between bifurcated and substantially parallel legs 48 of a front, fork-shaped, wheel supporting member.
  • a steering shaft 50 is connected to the front wheel supporting member at the center of the horizontal connection 49 between its two parallel legs 48.
  • the steering shaft extends upward in a direction roughly, but not quite, parallel to that of the parallel legs.
  • the steering shaft is pivotally mounted in a steering pivot, or tube 51. Standard sealed bearings are used at the top and bottom ends of the steering tube.
  • a front fork suspension system 52 is mounted on the steering shaft between the fork of the front wheel supporting member and the bearings below the steering tube 51.
  • this suspension is shown with a rubber cover, which is used to keep out dirt.
  • FIG. 4 the suspension is shown with this rubber cover removed.
  • This suspension includes a metal shaft 54 extending in the axial direction of the steering shaft. This shaft is fixedly connected to the lower part 56 of the steering shaft, which is connected to the horizontal connection 49 which forms the crown of the fork between the front legs 48.
  • the shaft 54 is positioned to slide in and out of a hollow axial cylinder formed in the bottom of an upper portion 58 of the steering shaft.
  • the shaft 54 can slide in and out relative to the upper portion 58 of the steering shaft, it cannot rotate relative to it, due to a slot and groove construction.
  • the slot and groove construction uses bearings to allow the in and out motion to take place without sticking.
  • the slots and grooves insure that steering of the front wheel can be accurately controlled by the rotation of the upper portion of the steering shaft 50.
  • a stiff compression spring 60 and two elastomer shock pads 62 placed at each end of the compression spring 60 function to absorb shock between the front wheel and the upper portion of the steering shaft which is mounted in the steering tube.
  • the top of the steering shaft 50 contains a telescoping section 64 which is collinear with the portion 66 of the steering shaft 50 that extends up above the steering tube 51.
  • the telescoping section 64 can be slid in and out of the portion 66 when the adjustment collar 68 is loosened, but is firmly locked relative to the portion 66 when the collar is tightened. This allows the handlebar 70 to be adjusted for riders of different height.
  • a metal handlebar connector 72 connects the handlebar to the top of the steering shaft, while spacing it approximately six inches in front of, and slightly above, the top of the steering shaft. In other embodiments handlebar can be mounted at other positions relative to the steering shaft.
  • the steering shaft 50 is slanted back at an angle of approximately thirty degrees from vertical.
  • the forked legs 48 of the front wheel supporting member are slanted back approximately two degrees more, forming a slight angle relative to the tilted steering shaft. Because of this angle between the forked legs and the steering shaft, when the steering shaft is rotated, the angle of the fork legs 48 relative to the ground changes.
  • the forked legs 48 point as fer forward as possible relative to the steering shaft, and, thus, they are in their most horizontal position. This allows everything which places weight upon them and the steering shaft to be as low as possible.
  • the forked legs point more downward from the steering shaft, and, thus, become slightly more vertical, raising up everything which places weight upon them.
  • the force of gravity tends to cause the front wheel to be self-righting, that is, to tend to point straight ahead.
  • the top ends of three lightweight tubular frame members 74, 76, and 78 are attached to the rear of the steering tube.
  • the bottom ends of these tubes are spaced diagonally downward from their upper ends, such that the bottom ends lie in a generally horizontal plane below the level of the axles of the front and rear wheels.
  • the top ends of the upper two of these three downward slanting tubes, tubes 74 and 76 are attached near a single point close to the top of the steering tube 51.
  • the lower portions of these upper two tubes 74 and 76 diverge from one another at equal angles relative to the longitudinal axis of the scooter, such that their bottom ends are spaced apart by approximately the width of the axle of the rear wheel and are equidistant from the bottom of the steering tube.
  • the top end of the lower of the three downward slanting tubes, tube 78 is attached near the bottom of the steering tube.
  • the bottom end of tube 78 is spaced forward of, and equidistant between, the bottom ends of tubes 74 and 76.
  • the top two downward slanting tubes 74 and 76 are angled down approximately one hundred and seven degrees from the slanting axes of the steering tube and shaft. Since the axes of the steering tube and shaft are angled down approximately thirty degrees from vertical, the downward slanting tubes 74 and 76 are at a total angle of approximately one hundred and thirty- seven degrees to vertical.
  • the lower downward slanting tube 78 is angled down approximately one hundred and nine degrees from the steering tube, or approximately one hundred and thirty-nine degrees off vertical. In other embodiments, the portion of the scooter's frame that descends down from the steering tube could descend at other angles.
  • the scooter 30 has a lightweight tubular bottom frame having two substantially horizontal, parallel side tubes 80 and 82 spaced apart by approximately the width of the rear axle 46.
  • the forward end of each of the side tubes 80 and 82 is attached to the lower end of that one of the top two downward slanting tubes 74 and 76 which extends to its side of the scooter.
  • the forward end of each side tube is also attached to the rear end of one of two horizontal diagonal tubes 84 and 86, which form the front of the substantially horizontal bottom frame formed by the front diagonal tubes 84 and 86 and the side tubes 80 and 82.
  • the front ends of the two front diagonal tubes 84 and 86 are joined together at the bottom end of the lower downward slanting tube 78.
  • the rear ends of the two roughly parallel side tubes 80 and 82 of the bottom frame act as a forked wheel supporting member for the rear wheel assembly.
  • the rear wheel assembly has generally the same dimensions and qualities as the front wheel assembly.
  • the rear wheel is rotably mounted on the rear axle 46, which in turn is mounted between two rectangular metal tabs 90 that extend up from near the rear ends of the two side tubes 80 and 82.
  • the upper two downward slanting tubes 74 and 76 could be extended and bent to form the two side tubes 80 and 82.
  • the rear fork assembly may include a suspension system, although a rear suspension system is not as important as a front one.
  • the side tubes 80 and 82, or extensions from them could be made of strong flexible structures which provides vibration and shock absorption, but which resist twisting. Other methods used to provide rear suspensions in wheeled vehicles could be used in other embodiments of the invention.
  • a platform 92 is positioned between the substantially parallel, horizontal side tubes 80 and 82, at a level which is approximately at or below the level of the front and rear axles. In some embodiments this platform can be even lower to provide greater stability.
  • the platform can be formed of wood, but it is preferred that it be formed of a lightweight material such as fiberglass and epoxy resin, or even lighter composite materials
  • the platform is angled so that its front is slightly higher than it back. Without a rider on the scooter the clearance underneath the side tubes 80 and 82 at the front of the platform is about eight and one half inches off the ground and at the rear of the platform is about seven and three quarters inches off the ground. This slant helps make the platform easier to keep one's footing on when traveling down steep hills..
  • the platform 92 in addition to having a horizontal portion as shown, also has a tilted portion which extends between the upper surfeces of the lower part the downward slanting tubes 74 and 76. This helps prevent the rider's feet from slipping forward off the platform when going down steep slopes.
  • the scooter 30 has a wheel base, that is a distance between its front and rear axles, of approximately 51 inches. It is preferred that the wheel base of adult versions of the scooters embodying the invention be at least 42 inches. This allows the scooter to have large radius wheels, a steeply slanted steering column, room for a rider to stand comfortably behind that steering column, and a high enough clearance to travel across rough terrain.
  • the scooter 30 has lightweight cable-actuated disk brake assemblies 96 and 98 mounted on the front and rear wheels, respectively.
  • the actuating cables which work each of these brakes extend to a respective hand-grip brake lever 100 mounted on the handlebar 70.
  • the brakes could be actuated by rods, electronic controls, or hydraulic actuation.
  • the brake on the rear wheel is powerful enough to lock the rear tire when the scooter is being ridden downhill, by a rider of the normal size for which the scooter has been designed, over most natural terrains at speeds of up to at least twenty miles per hour.
  • most natural terrains we mean most terrains found on the sides of mountains and hills, such as dirt, grass, snow, or gravel.
  • Locking the rear brake causes the rear wheel to break traction with the ground, making it easier to swing the rear of the scooter around in a sliding turn, much as one slides the back of snow skis around in a parallel turn.
  • Locking the front wheel is generally less desirable than locking the rear wheel, and, thus, in some embodiments, the front wheel can either have a weaker brake, a non-locking brake, or no brake at all. In some alternate embodiments other types of relatively strong brakes, such as the drum brake shown in FIG. 9, or the band brake shown in FIG. 10, are used.
  • the frame structure in the scooter 30 is made of tubular aluminum.
  • such tubing could be made of any material of sufficient strength, including steel.
  • Steel has the advantage of providing high durability and high weld strength and of being relatively inexpensive. Those for whom cost is of less concern will tend to prefer a body made of a lightweight material having a higher specific strength, that is, a higher strength to weight ratio, than steel, such as aluminum, titanium, and certain carbon fiber matrix composites. This is because the lighter the scooter, the more convenient, efficient, pleasant, and safe it will be to use.
  • FIG. 5 shows another embodiment of the invention, a scooter 30A, which uses a lightweight monocoque frame structure 104 rather than the tubular aluminum structure shown in the earlier figures.
  • a scooter 30A which uses a lightweight monocoque frame structure 104 rather than the tubular aluminum structure shown in the earlier figures.
  • monocoque structures can be fabricated of metal such as aluminum or titanium, as well as molded out of a fiber matrix composite material.
  • monocoque bodies have the advantage of being very lightweight relative to the structural strength which they provide and they allow much greater design flexibility than tubular construction.
  • the scooter 30A also includes fenders 110 and 112 over the front and rear wheels, respectively.
  • fenders have the disadvantage of addding the scooter's weight. They have the advantage of helping prevent mud, watet, dirt, and rocks from being thrown on the rider.
  • the front fender 110 is mounted between the front fork legs 48 near the top of those legs.
  • the rear fender 112 is part of the monocoque body 104. It is shaped to form a seat on which a rider of the scooter 30A can rest. In some embodiments the seat over the rear wheel can be substantially higher than that shown in FIG. 5. But in the preferred embodiments the seat is relatively low and out of the way, as is shown in FIG. 5, so it does not prevent the rider from instantly jumping on and off the scooter, and so that it does not prevent him or her from leaning back, leaning from side to side, or squatting while riding.
  • FIG. 6 is a partial view of an alternate embodiment of the invention in which the handlebar 70 is mounted on a shock absorbing suspension 114.
  • the suspension includes a block 116 which is bolted to the top of the upper, telescoping portion 64 of steering shaft.
  • a handlebar-carrying lever 118 in which the handlebar 70 is mounted, swings up and down about a pivot 120.
  • a shaft 121 also swings up and down in a generally parallel fashion about a lower pivot 122. This shaft pushes against a compression spring 124 and is connected to a hydraulic piston 126. The compression of the spring 121 pushing against the shaft 121 tends to hold the handlebar-carrying lever at the normal, desired height.
  • FIGS. 7 and 8 illustrate another embodiment of the invention in which protective padding is placed on some of the surfeces which faces a rider who stands on the platform looking forward.
  • two side shafts 130 stick out horizontally from each side of the upper, telescoping section 64A of the steering shaft 50, just below its top where the handlebar connector 72 is attached to it.
  • a cylindrical, high density foam pad 132 having an axial opening shaped to tightly fit around a side shaft 130, is placed over each such side shaft.
  • a similar cylindrical, high density foam pad 134 having an axial opening shaped to fit tightly around the upper portion 64A of the steering shaft 50 is placed over the upper portion 64A before it is inserted into the rest of the steering shaft.
  • a tight covering made of a material such as plastic or nylon cloth, be wrapped around the foam pads to protect them from dirt and abrasion, and to keep them in place, particularly during impact against a rider's body.
  • Such padding is desirable because, although the rider can normally safely step or fell to one side when the scooter fells, in some accidents, particularly those on steep terrain when the front wheel hits a large object, the rider may be thrown forward toward the steering shaft. It should be understood that in other embodiments of the invention, other types of, shapes of, and locations for padding can be used.
  • handle grips 138 are shown on the handlebar 70. It should be clear to those skilled in the art that such handle grips could be used on any embodiment of the invention.
  • FIGS. 11 and 12 show a hand-operable mechanism 160 used on some embodiments of the invention to allow the rider to quickly and easily adjust the height of the handlebar. This is important because it is important to have the handlebars at the right height for each person who is riding the scooter.
  • the mechanism 160 allows the user to unfix the top, telescoping section 64B of the steering shaft from the lower portion of that shaft 66B in which it is slidably mounted, so the handlebar which is mounted on the telescoping section 64B can be raised or lowered.
  • the mechanism 160 comprises a metal band 162 which can be tightened around the lower portion 66B by means of screws 164, the lower one of which is shown in FIG. 12.
  • the band has a hand-release lever 166 mounted on it which has a protrusion 168 sticking out of its inward pointing surface.
  • This protrusion is designed to fit through a correspondingly sized hole 170 in the lower part of the shaft 66B, and into one of a vertical series of correspondingly sized holes 172 placed along one side of the telescoping section 64B.
  • a spring 174 biases the hand-release lever inwardly against the steering shaft to insure that the protrusion 168 remains firmly in place inside the holes 170 and 172 unless the lever 166 is purposely pulled away from the steering shaft.
  • the protrusion 168 is pulled away from the holes 172 in the side of the telescoping section 64B, allowing that section to be slid in or out of the lower section 66B, so as to adjust the height of the handlebar.
  • the user can push the hand-release lever back against the steering shaft so the protrusion 168 will stick into a hole 172 and fix the telescoping section 64B at the current height.
  • the telescoping section 64B is mounted in the lower portion 66B of the steering shaft with a slot and groove construction using bearings to allow the telescoping section to slide without sticking and without the holes 172 getting out of alignment with the hole 170 in the shaft 66B.
