Patent ID: 7258363

Claim:
A landing gear assembly for supporting a trailer, the landing gear assembly comprising: a first leg and a second leg, each leg having a housing, an input shaft, a gear mechanism, and an extension potion, the housing being adapted to connect the leg to a trailer, the input shaft having a first end a portion and a second end portion, the input shaft extending through the housing and being axially movable between a first position and a second position and being rotationally movable, the gear mechanism being housed in the housing and having a high gear and a low gear, the gear mechanism being operatively connected to the input shaft such that the input shaft engages the low gear when in the second position and the input shaft engages the high gear when in the first position, the extension portion being telescopically movable with respect to the housing and being operatively connected to the gear mechanism such that rotation of the input shaft moves the extension portion with respect to the housing, the extension portion being movable a first distance when the input shaft is rotated one revolution while in the first position, the extension portion being movable a second distance when the input shaft is rotated one revolution while in the second position, the first distance being greater than the second distance; and a cross shaft adapted to operatively connect a first end portion of one of the input shafts with a second end portion of the other of the input shafts such that axial movement of one of the input shaft of the first and second legs causes axial movement of the other of the input shafts of the first and second legs and rotation of one of the input shaft of the first and second legs causes rotation of the other of the input shafts of the first and second legs; wherein the first and second legs are adapted to be attached to a trailer and connected to one another with the cross shaft such that when the input shaft of one of the first and second legs is moved to the first position the input shaft of the other of the first and second legs is moved to the first position and when the input shaft of one of the first and second legs is moved to the second position the input shaft of the other of the first and second legs is moved to the second position and when the input shaft of one of the first and second legs is rotated one revolution the input shaft of the other of the first and second legs is rotated one revolution.
