Abstract:
Improvements to work attachment assemblies and in particular work attachment assemblies for use with work machines such as excavators.

Claim (Index 1):
A coupler, comprising:\n a body; a first jaw that is moveable with respect to the body to engage a first pin on a work attachment; a second jaw that does not move with respect to the body, wherein the second jaw has an opening to a cavity, and wherein the opening is configured to enable a second pin on the work attachment to be inserted into the second jaw; an actuator having a first end and a second end, wherein the first end is connected to the first jaw to enable the actuator to move the first jaw; and a locking mechanism to secure the second pin in the second jaw, the locking mechanism to secure the second pin in the second jaws when inserted therein in use, the locking mechanism comprising a locking portion and a biasing element, wherein the locking portion is moveable to a locking position in which it at least partially obstructs the opening to the second jaw to prevent the second pin being withdrawn from the second jaw, wherein the locking portion is rigidly fixed with respect to the second end of the actuator so that the locking portion moves through the same path as the second end of the actuator, wherein the biasing element provides an urging force to urge the locking portion to bias the locking portion towards the locking position, and further wherein the coupler is configured such that contraction of the actuator causes the second end of the actuator to move, thereby also causing the locking portion to move sufficiently so as to enable the second pin to be removed from the second jaw when inserted therein.
