摘要:
A personal transportation device having first and second elongated foot support member that are arranged substantially in parallel and approximate to some extent the experience of skiing. The lateral distance of the foot support members may be adjusted. Biased-direction caster wheels may be provided that permit propulsion from side to side movement as well as kicking off and other propulsion techniques. Tiltable steering assemblies are disclosed that may impart a tilting of a front wheel to achieve turning. Various embodiments are disclosed.
摘要:
A motorized, fore-aft self-balancing transportation device that may include a single wheel structure with a drive motor, a battery and first and second foot platforms located on opposite sides of the wheel. The device may be uniquely be arranged such that the motor and battery are positioned such that there is space within the wheel envelope for a portion of the foot platform (positioned near or within the envelope), thereby placing the weight of the rider low and close to the center of gravity of the device. Various battery and motor arrangements are disclosed, as are different drive mechanisms and component redundancy to assure safe operation in the event of failure.
摘要:
An auto-balancing transportation device having a compact form. Left and right foot platform sections (20, 30) are coupled for fore-aft tilt angle movement relative to one another. Left and right wheels (21, 31) are provided under the respective foot platforms (22, 32). With a rider's weight directed primarily downward onto the wheels and not onto the coupling structure, the coupling structure (50) may have sufficient space to house the battery (48). In addition, more efficient and lighter weight supports and bearing arrangements may be used in the coupling structure.
摘要:
An auto-balancing transportation device having a wheel structure and foot platforms that pivot between an in-use and a stowed position. The pivot axis for each platform is provided within the wheel structure so that the force exerted by a rider when stepping on a foot platform is applied to the wheel structure at a point within the wheel structure, as opposed to external to it, which is unstable and may cause the device to tip over.

摘要:
Two skate wheel devices each with a foot placement platform, a frame and a wheel. The wheel rotates relative to the frame. The user inserts both feet into respective platforms within the skate wheel devices while the devices rest on pavement. After shifting weight to one of the wheel skate devices, the other raised so that the foot is generally horizontal as opposed to pointing to the pavement. The wheel skate device with the raised foot is then rolled to the side. The user then raises the other wheel skate device so that its foot also points generally horizontally and rolls that wheel skate device in the same direction as the other to build momentum. The platform may rock back and forth relative to the wheel. Grooved rollers may be sandwiched between spaced apart frame elements.
