Abstract:
1. An arm coupler for a loader machine, said arm coupler comprising: a body adapted to be connected to and extend between associated first and second loader machine arms, said body comprising first and second mounts located respectively adjacent opposite first and second ends of the body, said first and second mounts comprising respective first and second convexly curved mount faces adapted to abut stop faces of respective first and second stop blocks of an associated attachment; first and second plunger pins located respectfully at the opposite first and second ends of said body; at least one plunger actuator operatively connected to the first and second plunger pins, said at least one plunger actuator selectively operative to move the first and second plunger pins between a retracted position and an extended position, said first and second plunger pins projecting outward from the respective first and second opposite ends of the body a greater distance in the extended position as compared to the retracted position, wherein the first and second plunger pins are adapted to extend into apertures defined in first and second arm attachment ribs of the associated attachment, respectively, when the first and second plunger pins are located in the extended position; wherein said first and second plunger pins are coaxially located on a locking axis and move on said locking axis between their retracted and extended positions; said body further comprising first and second loader arm receiving locations located respectively between said at least one plunger actuator and said first and second opposite ends of said body that are adapted to receive first and second ends of the associated first and second loader machine arms, respectively, wherein said first and second plunger pins extend on said locking axis respectively through said first and second loader arm receiving locations and said first and second plunger pins are adapted to extend through and be slidably engaged with respective arm apertures defined in the associated first and second loader machine arm ends to capture the associated first and second loader machine arm ends in the first and second loader arm receiving locations, respectively, when said first and second plunger pins are located in and move between both said retracted and extended positions.
