Quick coupler assembly with dual hook members

Abstract

An coupling mechanism includes a cross member, left and right side members projecting from the cross member, and a pair of attaching members which are removably attached to the side members. Each attaching member has an elongated body, a first hook fixed to a first end of the body, and a second hook fixed to a second end of the body. The first hook has at least one dimensional feature which is smaller than a corresponding dimensional feature of the second hook. Each attaching member is mountable in a corresponding one of the side members in a first orientation with the first hook in an operative position and is mountable in a second orientation with the second hook in an operative position. A longer portion of each attaching member projects from a lower end of the corresponding side member when the attaching member is mounted in the first orientation. A shorter portion of each attaching member projects from a lower end of the corresponding side member when the attaching member is mounted in the second orientation. In another embodiment, the attaching members project by the same amount from the side members in their different orientations, and different upper center hooks are used to achieve different vertical spacings between the lower hooks and the center hook.
