  • Mechanical self-leveling walker
    Patent number: 12201579
    Abstract: As an example, a walker includes a first leg pair, a second leg pair and a cross beam connecting the first and second leg pairs in a parallel, spaced apart relationship. Each leg pair includes a U-shaped tube defining a front leg and a rear leg. A front strut is telescopically movable within the front leg and extends outwardly therefrom. A rear strut is telescopically movable within the rear leg and extends outwardly therefrom. A mechanical linear actuator includes a rotating element adapted to rotate relative to at least one of the front leg or the rear leg. The rotating element includes an interface with a track on the respective strut relative to which the rotating element rotates, whereby rotational motion of the rotating element translates to corresponding linear motion of the strut.
    Type: Grant
    Filed: June 7, 2023
    Date of Patent: January 21, 2025
    Assignees: The United States Government As Represented By The Department Of Veterans Affairs, Case Western Reserve University
