Detachable coupler assembly

An assembly for coupling an implement to an operating arm of a machine generally consisting of a first component including a base section fixedly mounted on a wall portion of the implement and an annular flange section disposed on an upper end of the base section, and a second component connectable to the operating arm, including a base section disposable in coupling relation with the first component, a pair of gripping members disposed on the base section and displacable into and out of gripping engagement with the annular flange section of the first component when the components are disposed in coupling relation and an actuator for selectively displacing the gripping members into and out gripping engagement with the annular flange section of the first component, each of the gripping members having a recess for receiving a segment of the annular flange section therein, having an end wall surface engagable with an annular end wall surface segment of the annular flange section, in gripping engagement, and upper and lower opposed wall surfaces for receiving the segment of the annular surface section therebetween.
