ABSTRACT:
A three-wheeled vehicle has three major frame components: the first two being spaced parallel bars disposed horizontally relative to the ground; the second being two bars hingedly connected to the first bars at an angle thereto and approaching each other at their second ends; the third being a third bar to which the second bars are hingedly attached intermediate the ends of the third bar. The first wheel pair supports the first frame member and the second steerable wheel supports the third frame member at one end. The other end of the third frame member carries a seat which is supported between the spaced bars of the first frame member. The seat is adjustable and the height of the frame components is also adjustable. The second wheel means is remotely controlled by hand controls provided at convenient locations on the first frame member. The first, second and third frame components may be locked in place for use and the walker may be collapsed in and upon itself for storage and transportation.
