ABSTRACT:
A lid opener apparatus is provided for use with a relatively large storage bin, and comprises a handle and structure for mounting and supporting the handle at a convenient height for manipulation by an operator. The mounting and support structure includes a first elongate link which has one end thereof pivotally mounted to the handle and the other end thereof pivotally mounted at a fixed location relative to the bin. A first elongate rod-like member is pivotally mounted to the same end of the link which receives the handle and extends upwardly to an area adjacent the top of the bin. A second rod-like member is pivotally coupled at one end thereof to the lid and extends outwardly to an area adjacent the uppermost end of the first rod-like member. A bell crank has three mounting portions arranged in a generally triangular configuration, and these three mounting portions are respectively pivotally coupled to the adjacent ends of the two elongate rod-like members and to the bin, preferably at an area where a sidewall and top wall thereof meet.
