Also disclosed is a device for releasing a trailer from a tractor and opening a door handle. The device comprises a shaft extending between a first end connected to a handle, and a second end connected to a lever, A hook is connected to the shaft proximate the second end, and the lever points generally opposite the direction of the hook. A tube is connected to the shaft proximate the second end. The tube has a passageway defined by at least one wall and at least one opening. ## Claims ### Claim 1 A device for releasing a trailer from a tractor and opening a door handle, the device comprising: a shaft extending between a first end connected to a handle, and a second end connected to a lever; a hook connected to the shaft proximate the second end, the lever pointing generally opposite the direction of the hook; a tube connected to the shaft proximate the second end, the tube having a passageway defined by at least one wall and at least one opening; and wherein the passageway is sized to receive a door handle. ### Claim 2 (depends on 1) The device of claim 1, wherein the at least one opening comprises a first opening and a second opening which is concentric with the first opening. ### Claim 3 (depends on 1) The device of claim 1, wherein the at least one wall comprises four individual walls oriented so that the passageway is rectangular. ### Claim 4 (depends on 1) The device of claim 1, wherein the hook has a first linear segment and a second linear segment connected to the first linear segment, the first linear segment extending orthogonally outward from a surface of the shaft, and the second linear segment extending at an angle from the first linear segment toward the handle, the second linear segment and the axis of the shaft being skew. ### Claim 5 (depends on 1) The device of claim 1, wherein the lever has a first linear section extending at a right angle from the second end of the shaft, and a second linear section extending at a right angle from the first linear section and parallel to the axis of the shaft. ### Claim 6 (depends on 5) The device of claim 5, wherein the tube is disposed on the shaft so that it is contacting the second end of the shaft and the first linear section of the lever. ### Claim 7 (depends on 5) The device of claim 5, wherein the lever has a third linear section extending at a right angle from the second linear section and parallel to the first linear section. ### Claim 8 (depends on 7) The device of claim 7, wherein the third linear section has a length that is less than a length of the first linear section. ### Claim 9 (depends on 7) The device of claim 7, wherein the lever has a fourth linear section extending from the third linear section and parallel to the second linear section. ### Claim 10 (depends on 9) The device of claim 9, wherein the fourth linear section has a length that is less than a length of the second linear section. ### Claim 11 (depends on 1) The device of claim 1, wherein the tube abuts the second end of the shaft. ### Claim 12 (depends on 1) The device of claim 1, wherein the at least one opening of the tube includes a first opening and a second opening opposite the first opening; and the at least one wall of the tube is solid and extends continuously from the first opening to the second opening thereby inhibiting access into the passageway between the first opening and the second opening. ### Claim 13 (depends on 1) The device of claim 1, wherein the passageway is sized to receive a door handle of an intermodal container. ### Claim 14 A device for releasing a trailer from a tractor and opening a door handle, the device comprising: a shaft extending between a first end connected to a handle, and a second end connected to a lever; a hook connected to the shaft proximate the second end, the lever pointing generally opposite the direction of the hook; a tube connected to the shaft proximate the second end, the tube having a passageway defined by at least one wall and at least one opening, wherein the at least one wall comprises four individual walls oriented so that the passageway is rectangular. ### Claim 15 A device for releasing a trailer from a tractor and opening a door handle, the device comprising: a shaft extending between a first end connected to a handle, and a second end connected to a lever, the lever including: a first linear section extending at a right angle from the second end of the shaft; a second linear section extending at a right angle from the first linear section and parallel to the axis of the shaft; and a third linear section extending at a right angle from the second linear section and parallel to the first linear section; a hook connected to the shaft proximate the second end, the lever pointing generally opposite the direction of the hook; and a tube connected to the shaft proximate the second end, the tube having a passageway defined by at least one wall and at least one opening. ### Claim 16 (depends on 15) The device of claim 15, wherein the third linear section has a length that is less than a length of the first linear section. ### Claim 17 (depends on 15) The device of claim 15 wherein the lever has a fourth linear section extending from the third linear section towards the first linear section. ### Claim 18 (depends on 17) The device of claim 17, wherein the fourth linear section has a length that is less than a length of the second linear section. ### Claim 19 (depends on 15) The device of claim 15, wherein the hook has a first linear segment and a second linear segment connected to the first linear segment, the first linear segment extending orthogonally outward from a surface of the shaft, and the second linear segment extending at an angle from the first linear segment toward the handle, the second linear segment and the axis of the shaft being askew.
