  • Latching mechanism
    Patent number: 5013178
    Abstract: A latching mechanism comprises a cam operated pivoting member within a first cylinder. The member has a lug which can project through an aperture in the cylinder. The cylinder slides into a second cylinder which has a corresponding aperture to receive the projected lug.The pivotting member has no internal axis of pivot. Instead it has a rolling axis depending on the position of the cam and a rocking axis about a shoulder of the member in contact with the interior wall of the first cylinder.This results in a small, light-weight structure.
