Claim:
A cargo restraint locking mechanism, comprising: a control member pivotally movable between a locked position, an engaged position and a disengaged position, said control member having a handle portion and said handle portion having a first end, said control member having a forked portion spaced from said first end and said forked portion having a pair of substantially identical spaced apart handle arms, each of the pair of handle arms defining a plurality of cam surfaces adjacent to each other, the plurality of cam surfaces comprising a locking cam surface, a disengaging cam surface, and an engaging cam surface; a control pin extending outwardly from each of said handle arms; an axle member extending through an axle aperture in each of the handle arms, the axle member including body portion defining a threaded aperture extending therethrough; a tension stud having a base portion and a threaded shaft that is threadably mated with the threaded aperture in the axle member, the base portion of said tension stud configured to maintain clamping engagement with the track when the control member is in said locked position thereof and said base portion of said tension stud is released from clamping engagement with the track for said control member is in said engaged position and in said disengaged position; a spring member mounted on said tension stud; a lift arm having a first end wall and a pair of spaced apart side walls extending from said first end wall to a second end, the lift arm disposed in concert with the control member such that the respective side walls of the lift arm are disposed in parallel and next to respective handle arms of the control member, each of the side walls of the lift arm defining a first slot, and said first slots having a back end and a front end, and opposed ends of the axle member extending through the respective first slots, and each including an edge that defines a guide surface that slidingly receives the control pin and each of the side walls further defining a lift slot; a plunger with a plunger stem and a plunger head, the plunger being spaced from said tension stud and operatively connected to said lift, and said plunger configured to translate between a locked position where the plunger head is configured to be received within an aperture in the track and a disengaged position where the plunger head is lifted out of the aperture in the track, said plunger stem having walls defining an aperture therethrough; a pin slidably extending through both of the lift slots in said lift arm and through the aperture in the plunger stem, the pin configured to slide within the lift slots such that rotation of the lift arm results in linear movement of the plunger due to the pin sliding within the lift slots.
