AI Technical Summary

Benefits of technology

[0008] The caster assembly may be decoupled from the ground-contacting module without the use of a tool, and may include a suspension mechanism for dampening transmission of vibration to the vehicle.

Problems solved by technology

The vehicle also has a motorized drive arrangement, mounted to the ground-contacting module that causes automatically balanced operation of the vehicle in an operating position that is unstable with respect to tipping when the motorized drive arrangement is not powered.

Embodiment Construction

[0034] Various Referring to FIG. 1A, a side view is shown of a personal vehicle, designated generally by numeral 10. Vehicle 10 may be described in terms of two fundamental structural components: a support 12 for carrying a passenger 14 or other load, and a ground-contacting module 16 which provides for transportation of support 12 across the ground, or, equivalently, across any other surface. The passenger or other load may be referred to herein and in any appended claims as a “payload.” As used in this description and in any appended claims, the term “ground” will be understood to encompass any surface upon which the vehicle is supported.

[0035] A mechanism and process for automatically balanced operation of the vehicle in an operating position that is unstable with respect to tipping when the motorized drive arrangement is not powered is described in Kamen '965 column 3, line 55 through column 5, line 44.

[0036] Referring further to FIG. 1A, the modes of operation described herei...

Description

[0001] This application is a divisional application of Ser. No. 10 / 818,386, filed Apr. 5, 2004, which in turn was a divisional application of Ser. No. 09 / 978,711, filed Oct. 16, 2001, which was a divisional application of Ser. No. 09 / 325,463, filed Jun. 3, 1999. Each of these applications is hereby incorporated herein by reference.FIELD OF THE INVENTION [0002] The present invention pertains to mechanical improvements to personal vehicles including self-propelled personal vehicles. BACKGROUND ART [0003] Personal vehicles, such as may be used by handicapped persons, may be self-propelled and user-guidable, and, further, may entail stabilization in one or more of the tore-aft or lateral planes, such as when no more than two wheels are in ground contact at a time. More particularly, such vehicles may include one or more clusters of wheels, with wheels in each cluster capable of being motor-driven independently of the cluster in its entirety. One example of such a vehicle is described in...
