Abstract:
1. A coupler for coupling an accessory to an excavator arm of an excavator, the coupler comprising first and second jaws associated with first and second latching mechanisms, respectively, for latching first and second attachment pins of the accessory within the respective first and second jaws, the first latching mechanism comprising a jaw closing member that is pivotally mounted relative to the first jaw, that jaw closing member at least partially closing the first jaw when positioned in a jaw closing position, and that jaw closing member having extending therefrom, within the framework of the coupler, an arm, the arm being selectively engageable by the second latching mechanism and resiliently flexible along at least a part of its length such that when the first latching mechanism is latching the first attachment pin of the accessory in the first jaw, the arm will resiliently flex, rather than plastically flex when a force is applied at or near its free end by the second latching mechanism being opened.
