Abstract
A coupling assembly (10) for demountably attaching a work implement (15) to a prime mover (13). The prime mover (13) has a lifting mechanism (18, 118) and a tilting mechanism (23, 123). The coupling assembly (10) includes a master coupling element (11, 111) adapted to be mounted on the lifting and tilting mechanisms (19 and 20) of the prime mover (13) and an implement coupling element (12, 112) adapted to be atached to the work implement (15). The master coupling element (11, 111) has a frame (25, 125) with upper and lower transverse beam members (26 and 31 or 126 and 131). An aligning horn (28, 128) extends upwardly from the frame (25, 125) of the master coupling element (11, 111). A first, forwardly directed bearing surface (60, 160) extends along the upper transverse beam member (26, 126), and a second, forwardly directed bearing surface (61, 161) extends along said lower transverse beam member (31, 131). The implement coupling element (12, 112) has upper and lower, transversely oriented support members (79 and 82 or 179 and 182). A receiver (29, 129) is presented from the upper support member (79, 179) to be operatively engaged by the aligning horn (28, 128). A first, rearwardly directed bearing surface (81, 181) extends along the upper support member (79, 179), and a second, rearwardly directed bearing surface (83, 183) extends along the lower support member (82, 182). A locking mechanism (30, 130) releasably secures the implement coupling element (12, 112) to the master coupling element (11, 111). The first and second bearing surfaces (60 and 61 or 160 and 161) on the master coupling element (11, 111) are engaged by the first and second bearing surfaces (81 and 83 or 181 and 183), respectively, on the implement coupling element (12, 112) when the aligning horn (28, 128) is operatively engaged within the receiver (29, 129) and the locking mechanism (30, 130) has secured the implement coupling element (12, 112) to the master coupling element (11, 111).
