A walker for a handicapped person has a pair of base rails juxtaposed, and a pair of front posts extend therefrom. Each front post is attached to a front of a respective rail. A first pair of rotation-changeable motors drives a pair of actuators, initially pointing upwardly. A first pair of gear reduction devices, which in combination with a pair of rear posts, can be rendered tiltable, has respective input shafts coupled to respective output shafts of the motors. The pair of tiltable rear posts are extendable or retractable by rotation-sense selection of the first pair of motors. A pair of crutch supports are in contact with the rear posts, Which fit under the armpits of the handicapped person. A pair of levers which extend outwardly and downwardly from the pair of crutch supports, respectively, are bent rearwardly, and equipped with handles. A second pair of rotation-changeable motors are attached to the pair of front posts, respectively, and a second pair of length-adjustable gear-reduction mechanisms are coupled to the second pair of motors, and also to the pair of the rear posts, respectively, so as to be operative, upon length adjustment, between forward-and rearward-positions. A switch is connected to the first and second pairs of motors for separate selection of the height and inclination of the rear posts, respectively, by selective choice of the motor\s sense-of-rotation and travel.

A transfer walker for a handicapped person, comprising in combination a pair of base rails juxtaposed, and generally running in parallel with one another along a normally horizontal direction, each of said base rails having a front and a rear end, a pair of first posts normally extending upwardly, and in parallel with one another in a direction generally at right angles with a respective base rail direction, each of said pair of first posts being attached to a respective of said rails near respective front ends thereof, a pair of second posts normally extending upwardly, and in parallel with one another in a direction generally at right angles with a respective base rail direction, each of said pair of second posts being pivotally attached to a respective of said rails near respective rear ends thereof, so as to be tiltable, two pairs of length-adjustable and rotatably energizable gear reduction means, and rotatable and tiltable coupling means combined therewith, respectively, each of said length-adjustable and rotatably energizable gear reduction means and rotatable and tiltable coupling means combined therewith having respective output shafts, said output shafts of a first pair of said length-adjustable and rotatably energizable gear reduction means and rotatable and tiltable coupling means combined therewith running generally in parallel with one another, and being upright in an inoperative rest position thereof, and a pair of crutch supports having undersides, and being in operative contact with said output shafts of said first pair of said length-adjustable and rotatably energizable gear reduction and rotatable and tiltable coupling means combined therewith, respectively, on said undersides, being spaced at an adjustable distance from one another, and adapted to fit under the armpits of the handicapped person, a pair of length-adjustable levers extending outwardly and generally downwardly from locations near respective ends of said pair of crutch supports, said pair of levers being bent rearwardly near lower ends thereof, and a pair of easily gripable handles being attached thereto, and extending rearwardly from said lower ends of said levers, respectively, a second pair of said length-adjustable and rotatably energizable gear reduction means and rotatable and tiltable couplings means combined therewith being pivotally coupled near first ends thereof to top ends of said pair of first posts, respectively, and being pivotally and slidably coupled with the other ends thereof to said pair of hollow second posts, respectively, so as to be operative upon length adjustment thereof to effect a change of respective of said pairs of hollow second posts in a rearward direction, and back therefrom, up to a range of inclination of about 30°from the vertical, and operator-handlable switch means connected to respective of said first and second pairs of said length-adjustable and rotatably energizable gear reduction means and rotatable and tiltable coupling means combined therewith for separate adjustment of the height and inclination of said second pair of posts respectively, by selective choice of sense-of-rotation and time-duration of each of said pairs of length-adjustable and rotatably energizable gear reduction means and rotatable and tilting means combined therewith, respectively, whereby the handicapped person can move between sitting and upright positions.
