Quick coupler for excavation equipment

A quick coupler for attaching a tool to an excavator comprising:

• a coupler body comprising a pair of spaced parallel plates, said plates defining means for fixed attachment of said quick coupler at the end of the excavator, said plates defining a first slot facing in a first direction, said first slot adapted for engagement upon a first pin on the tool, and a second slot facing in a second direction, said second slot adapted for engagement upon a second pin on the tool, the first pin and the second pin being substantially parallel, and a third plate, mounted between and substantially perpendicular to said pair of spaced parallel plates;
• and
• a latch mechanisms mounted to said coupler body for securing engagement of said second slot upon the second pin, said latch mechanism comprising a coupler gate rotatably mounted on an axis transverse to a longitudinal axis of the second pin, so that the gate pivots about said transverse axis between a first position in which engagement of said second slot upon the second pin is secured by said gate, and a second position in which said gate is clear of said second slot;
• and a latch lever mounted upon said coupler gate, said latch lever comprising a tab portion for engaging in a third slot defined by said third plate, said latch lever being rotatably mounted to pivot between a first position, in which said tab engages in said third slot, in a manner to resist rotation of said coupler gate, and a second position in which said tab is clear of said slot, thereby to allow rotation of said coupler gate.
