Patent ID: 8007010

Claim:
A hydraulic line attachment device comprising: (a) a first assembly comprising a first frame, a plurality of first hydraulic line couplers, and a first coupling member; (b) a second assembly comprising a second frame, a plurality of second hydraulic line couplers, and a second coupling member; (c) the plurality of first hydraulic line couplers and the plurality of second hydraulic line couplers are constructed so that they are closed to flow of hydraulic fluid therethrough when disengaged, and open to flow of hydraulic fluid there through when engaged; (d) at least one of the first coupling member and the second coupling member comprises a shaft having a pin, the shaft being constructed to engage the other of the first coupling member and the second coupling member, and wherein the other of the first coupling member and the second coupling member comprises a cam comprising a cylinder and a spiral track for engaging the pin, wherein the cam engages the shaft and the pin so that as a result of rotation between the shaft and the cam when the pin is engaged in the spiral track, the plurality of first hydraulic line couplers and the plurality of second hydraulic line couplers are engaged or are disengaged depending on the direction of rotation; and (e) a handle coupled to one of the first coupling member or the second coupling member so that moving the handle causes engagement and disengagement of the plurality of first hydraulic line couplers and the plurality of second hydraulic line couplers when the pin is engaged in the spiral track, and wherein the handle is constructed to rotate in a plane perpendicular to an axis of movement of the plurality of first hydraulic line couplers and the plurality of second hydraulic line couplers when moving into or out of engagement, and wherein the plane crosses the axis.
