ABSTRACT:
Landing gear for supporting a vehicle including a body for attachment to the vehicle, and a tubular leg carried by the body and having a sliding fit with the body for up and down movement relative to the body. The landing gear further includes a mechanism for slidably moving the leg up and down relative to the body. The mechanism includes a nut inside the tubular leg having a threaded bore, an upper bulkhead extending across the inside of the leg adjacent the upper end of the leg, and a lower bulkhead extending across the inside of the leg below the upper bulkhead for supporting the nut in a generally fixed position relative to the leg between the upper and lower bulkheads. Both the upper and lower bulkheads include openings aligned with the threaded bore of the nut. The mechanism also includes a screw shaft in threaded interconnection with the threaded bore of the nut and extending axially in the tubular leg, and a bearing in the body above the leg journalling the screw shaft for rotation on its axis. The screw shaft extends downward from the bearing through the nut and through the openings in the upper and lower bulkheads so that rotation of the screw shaft in one direction is operable to move the leg upward relative to the body and rotation of the screw shaft in an opposite direction is operable to move the leg downward relative to the body.
