Abstract:
1. A locking system actuated by a lever for a prosthetic leg or arm socket, the locking system comprising: a limb liner for installation on a residual limb, the limb liner having a liner pin; a lock comprising: a housing for connection to a prosthetic socket, the housing having a first end and a second end and an axis between said first end and second end, an axial bore at or near said axis of the housing, and a radial bore; a lock shaft slidable in the radial bore and having an outer end that is outside the housing, and an inner end, the lock shaft being biased to a position wherein the inner end extends into the axial bore and engages the liner pin when the liner pin is inserted into the axial bore from said first end, so that the liner pin slides in the axial bore relative to said inner end of the lock shaft toward said second end but not toward said first end; and a lever outside the housing having a first end and an opposite second end, wherein the lever comprises a pivotal connection to the outer end of the lock shaft between said first end and said second end, and wherein said second end is adapted so that, when the lever is pivoted relative to the lock shaft at said pivotal connection to an unlatched position, said second end pushes against and slides against an outer surface of the housing to move said pivotal connection outward from the housing to pull the lock shaft outward so that said inner end is distanced from the pin.
