Patent ID: 8469623

Claim:
A coupling device for securing a primary mover to a work tool, comprising: a first coupling body including a relative forward portion, a relative rearward portion, a relative right side portion, and a relative left side portion, the first coupling body being interconnectable with a second coupling body to form: (i) a first connecting interface having a first mating connection between the first and second coupling bodies at a first, relatively forward-left position on the first coupling body and a second mating connection between the first and second coupling bodies at a second, relatively forward-right position on the first coupling body, and (ii) a second connecting interface having a third mating connection between the first and second coupling bodies at a third, relatively rearward-left position on the first coupling body and a fourth mating connection between the first and second coupling bodies at a fourth, relatively rearward-right position on the first coupling body; and a rotary wedge member connected to the first coupling body and rotatable to secure together the first and second coupling bodies; an actuator coupled with the rotary wedge member and operable to rotate the rotary wedge member relative the first coupling body about an axis positioned relatively rearward of at least one of the third and fourth positions, the rotary wedge member including a slot formed with a wedge surface therein configured to contact the second coupling body upon interconnecting the first and second coupling bodies, the wedge surface extending about the axis and defining a plurality of progressively smaller radiuses relative the axis at a plurality of progressive angular locations upon the wedge surface; the first connecting interface comprises a first trunnion arrangement; the second connecting interface comprises a second trunnion arrangement spaced a first distance apart from the first trunnion arrangement; the rotary wedge member is interconnectable with the second coupling body to form a third connecting interface comprising a third trunnion arrangement spaced a second distance apart from the first trunnion arrangement and a third distance apart from the second trunnion arrangement, and the second distance is greater than the first distance; and the third trunnion arrangement is formed on the second coupling body and engagable with a third slot arrangement on the rotary wedge member.
