Coupler Horseshoe
A coupler (10) comprising a top part (14) for attaching to an excavator and a bottom part for attaching to an accessory, the bottom part comprising a first jaw 18 that opens in a forwards direction for receiving a first attachment pin 34 and a second jaw 20 opening downwards and receiving a second pin 36, wherein the second jaw is associated with a latching member (22) that sweeps between an open condition and closed condition for securing the second attachment pin of the accessory in the second jaw, the second jaw comprising an upper wall surface (56) and a wedging surface 32, the wedging surface being closer to the front of the coupler than the upper wall surface. The latching member may be pivoted or sliding, the latching member may have a tip and a recess 40 behind a lip 38 on the tip. The lip may be substantially perpendicular to a radial arm of the hook. The tangent 74 of contact point 76 of the tip with the pin may define a range of intersections 82 with the tangent 78 of the contact point 80 with the wedge surface, there may also be a sprung member to retain the pin.
