DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0056] According to one embodiment of the present invention, there is provided an adult personal transporter 100 as shown in FIG. 1. The transporter 100 includes a support 102 for supporting a standing driver 104. Three wheels 106 (i.e. ground engaging devices) engage the ground during transport. An electric drive (not shown) is provided for driving at least one of the wheels 106 to propel the transporter 100. The transporter 100 also includes a handle bar 108 for enabling the driver 104 to control at least one of the wheels 106 to steer the transporter 100. Advantageously, the three wheels 106 provide improved dynamic stability and balance, and can carry greater loads when compared with the two wheels of a Segway.

[0057] The transporter 100 includes three wheels 106 in the form of one front wheel and two rear wheels. The transporter 100 includes an oblique steering arm 110 for improved stability, and that extends between the handle bar 108 and front wheel 106 which it steers. The handle bar 108 controls the single front wheel 106. The transporter 100 also includes an overall frame 112 including a pair of rearwardly extending oblique arms 114 supporting respective rear wheels 106.

[0058] As can best be seen in FIG. 2, the angle between the steering arm 110 and oblique arms 114 is between 70 and 80 degrees. Another oblique arm 116 extends from the handle bar 108 to support the front of the support 102. The angle between the steering arm 110 and the other arm 116 is about 54 degrees. The frame 112 is lightweight and includes metal alloy, steel, carbon fibre, aluminium and/or chrome molybdenum steel. The transporter 100 further includes independent shock suspension 116 for each wheel. The suspension 116 includes a concealed compression spring.

[0059] Each wheel 106 includes an inflatable tyre which can be low pressure for off-road use. The transporter 100 further includes disc brakes 118 on each wheel 106. The handle bar 108 includes a brake actuator for actuating the brakes 118. The handle bar 108 further includes a drive actuator for actuating the electric drive. The drive actuator can be hand grip controlled or digit (e.g. finger or thumb) actuated.

[0060] The electric drive includes an electric motor. The electric drive can further include a gearbox coupled between the motor and the wheels 106. The electric drive typically drives the front wheel 106 and/or the rear pair of wheels 106. The transporter 100 further includes a rechargeable battery for powering the electric drive. The depleted battery can be replaced with a pre-charged replacement battery. Alternatively, the depleted battery can be charged either whilst removed from or remaining on the transporter 100. The battery can be either fastened to a frame of the transporter or located beneath the support 102. The transporter 100 further includes a charger for charging the battery.

[0061] The support 102 includes a platform for supporting the standing adult driver 104. The platform is sized to support two forward facing feet. The transporter 100 also has a GPS for locating the transporter 100 in the event of theft.

[0062] FIG. 3 shows that the outer rear wheels 106 of transporter 100 can be angled toward each other for improved stability.

[0063] FIG. 4 shows a snow personal transporter 400 with a front skid 402 (i.e. ground engagement means) and a pair of rear tracks 404 (i.e. ground engagement means).

[0064] FIG. 5 shows a child's personal transporter 500. The front wheel 502 is larger than the rear wheels 504 to facilitate steering and lowering the standing platform 506 for children. FIG. 6 shows a wheelchair personal transporter 600 with a platform 602 sized to accommodate a wheel chair 604.

[0065] FIG. 7 shows an off-road personal transporter 700 with releasable trailer 702. The robust transporter 700 is suitable for military operations.

[0066] FIG. 8 shows a golf personal transporter 800. The transporter 800 includes a holder 802 for holding golf clubs 804. Other holders may be provided for holding other accessories. The holders can hold any one of: a gun, a cross bow, camping equipment, a drink bottle and bags.

[0067] FIG. 9 shows a drifting personal transporter 900, similar to the child's personal transporter 500. The front wheel 902 is larger than the rear wheels 904 to facilitate steering and lowering the standing platform 906 for children. The rear wheels 904 are configured to slide out during drifting maneuvering of the transporter 900. In particular, the wheels 904 either include grip-less covers or can be molded from thermoplastic material to provide a smooth and rigid ground contacting surface. The grip-less covers are moulded rings located around tires which can then be inflated to hold the rings in place.

[0068] An electric motor drives the front wheel 902, and disc brakes 908 retard rotation of the front wheel 902 responsive to pulling a hand brake actuator 910. In practice, the driver can actuate the electric motor and disc brakes 908 to control the degree of slide of the rear end of the transporter 900 during drifting. The transporter 900 can be maneuvered to: travel in a straight line, slide out to rotate through 360 degrees, and then continue in a straight line once more. The wheels also include a smaller tail wheel 912, at the back of the platform 906, that engages the ground as the transporter 900 performs a wheelie with the front wheel 902 off the ground. In use, the transporter 900 can be trick maneuvered so that only the front wheel 902 and one of the rear wheels 904 remains in contact with the ground when moving.

[0069] The transporter 900 can perform a zero turn with a turning radius that is substantially zero, even with a trailer connected. In particular, by turning the driven front wheel 902 at 90 to the rear wheels 904, the transporter can turn with the free rear wheels 904 remaining about the same location. In fact, the front wheel 902 can be rotated in excess of 270, and through 360.

[0070] FIG. 10 shows a wheel 1000, whether a front wheel 902 or one of the rear wheels 904. The wheel 1000 includes a lightweight central electric motor 1002. The highly efficient electric motor 1002 includes a hub stator 1004 including armature windings, and a rotor 1006 surrounding the hub stator 1004. The wheel 1000 also includes an outer rim 1008, and spokes 1010 extending from the rotor 1006 to the rim 1008. The motor 1002 may be driven in reverse.

[0071] Turning to FIG. 10d, the transporter furthers include a anti-locking brake assembly 1012 for braking the wheel 1000. The brake assembly 1021 includes a brake ring 1014 coupled to the rotor 1006. The brake assembly 1021 further includes a clover-shaped brake pad 1016 for engaging with the brake ring 1014. The rubber brake pad 1016 engages the brake ring 1014 at multiple locations.

[0072] FIG. 11 shows an alternative braking assembly where the rubber brake pad 1100 engages the brake ring 1102 at a single location.

[0073] The braking systems above may be regenerative braking systems which convert the kinetic energy of the wheel into electricity stored in the battery during braking.

[0074] FIG. 12 shows a transporter 1200 fitted with a delivery container 1202 and a trailer 1204. The container 1202 includes a proximity lock for locking the container 1202 when a key is not detected within a predefined proximity of the container 1202. Typically, the driver is a courier carrying the key so that items can be removed from the container 1202 and then the container 1202 is locked when the driver leaves the transporter 1200 to deliver the items. The transporter 1200 includes a rail barrier 1208 on one side only (traffic side) for impeding dismounting of the driver from that side. The container 1202 supports payloads in excess of 200 kg and so the transporter 1200 is robust.

[0075] The transporter 1200 further includes a heater or cooler for controlling the internal temperature of the container 1202 when delivering heated goods (e.g. pizzas) and chilled goods (ice cream) respectively. The container 1202 is a module and releasable relative to the driver support 1206.

[0076] Turning to FIG. 13, the transporter 1200 further includes another cleaning container 1300 for substituting the packages container 1202. The transporter 1200 can further include a pole-mounted surveillance camera 1302 to capture and transmit images to security in a shopping centre.

[0077] Turning to FIG. 14, the transporter 1200 further includes an safety enclosure 1400 for substituted in place of the packages container 1202. The safety enclosure 1400 for encloses a standing cameraman 1402 (e.g. passenger) taking images at a sporting event.

[0078] FIG. 15 shows an alternative wheelchair transporter 1500 in which the support 1501 is configured to support a wheelchair 1502. The transporter 1500 includes a loading means 1502 to facilitate rear loading of the wheel chair 1504 onto the support 1501. The loading means 1502 includes a foldable ramp 1506 which can be folded and locked in place to form a rear barrier to the wheelchair 1504 inadvertently falling from the rear of the transporter 1500. Furthermore, rear wheel hubs 1508 prevent sideways slipping of the wheelchair 1504 from the support 1501. In an alternative embodiment, the loading means 1502 includes the support 1501 which is at least in part angled toward the ground or slides for extending from the support 1501 to the ground.

[0079] The wheelchair 1504 can be located so that a driver of the transporter is seated in the wheelchair. The transporter 1500 further includes a lock for locking the wheelchair 1504 in place. The transporter 1504 further includes a speed limiter. The speed limiter limits the speed of the transporter 1500 based upon the activation of the lock, in accordance with an entered speed threshold (e.g. 20 km/h), or a received speed limit of a zone in which the transporter is located that is RF transmitted to the transporter 1500 by a governance authority. The battery 1510 is fastened to a frame of the transporter 1500.

[0080] FIG. 16 shows the wheelchair transporter 1500 with a handlebar 1600 moved into an upright position for a standing driver 1602. The handlebar 1600 includes an inside handgrip 1604 and an outside handgrip 1606 for each hand. The handlebar 1600 further includes controllers for actuation when a hand is on either grip 1604, 1606.

[0081] The transporter 1500 includes no axle, or axle-less rear wheels 1608, so that the support 1501 can be situated at or beneath the centre of the rear wheels 1608 to provide a low centre of gravity and improve stability.

[0082] FIG. 17 shows a golf transporter 1700. The transporter 1700 includes a carriage 1702 mounted forward of the driver support 1704 using an interconnecting articulator 1706.
