  • Adjustable jack stand
    Patent number: 6443413
    Abstract: An improved adjustable jack stand combines a ratchet and pawl height maintenance mechanism with a pin and hole mechanism wherein the holes in the post coordinate with the teeth in the post so that any engagement between the pawl and a tooth ensures that a pair of holes in the base and the post are aligned to receive a pin. Additionally, the pin defines a circular cylindrical shape, and each of the pin support sections likewise defines a corresponding bottom half of a circle, thereby exposing the targeted hole in the ratchet bar for easy viewing by the mechanic. An elongated tether is provided and has one section connected to the body and another section connected to the pin.
