Landing gear for a vehicle such as a trailer, comprising a leg, a foot at the lower end of the leg adapted for engagement with the ground, a pair of generally channel-shaped members forming a tube which extends up from the foot and telescopically receives the lower end of the leg, an elastomeric member disposed in the tube between the lower end of the leg and the foot, and a bearing plate in the tube interposed between the elastomeric member and the lower end of the leg. The tube is attached to the lower end of the leg to permit limited telescopic movement of the leg and the foot whereby the foot is adapted to move upwardly relative to the leg as the landing gear accepts the weight of the vehicle thereby resiliently to compress the elastomeric member between the foot and the bearing plate. A method of making the foot and tube of the landing gear is also disclosed.
Landing gear for a vehicle such as a trailer, comprising a leg, a foot at the lower end of the leg adapted for engagement with the ground, a pair of substantially identical generally channel-shaped members each having a web and a pair of generally parallel flanges extending away from the web and terminating in edges, the members being disposed so that the edges of the flanges of one channel-shaped member face the edges of the flanges of the other channel-shaped member to form a tube of generally rectangular cross section which extends up from the foot and telescopically receives the lower end of said leg, an elastomeric member disposed in the tube between the lower end of the leg and the foot, bearing plate means on the tube interposed between the elastomeric member and the lower end of the leg, and means attaching the tube to the lower end of the leg and permitting limited telescopic movement of the leg and the foot whereby said foot is adapted to move upwardly relative to the leg as the landing gear accepts the weight of the vehicle thereby resiliently to compress the elastomeric member between the foot and said bearing plate means.
Landing gear for a vehicle such as a trailer, comprising a leg, a foot at the lower end of the leg adapted for engagement with the ground, said foot comprising a metal plate having a central portion and an outer portion surrounding said central portion, a plurality of upwardly-projecting ribs in said outer portion of the plate radiating outwardly from said central portion of the plate, a metal tube generally rectangular in horizontal cross section extending up from the foot and receiving the lower end of said leg, said tube being welded at its lower end to said central portion of the plate and at its sides to the inner ends of said ribs, each rib being of generally inverted-V shape in transverse cross section and having a shoulder at its inner end sufficiently wide to engage a respective corner of the tube and portions of the side walls adjacent the corner, an elastomeric member disposed in the tube between the lower end of the leg and the foot, bearing plate means in the lower end of the leg and the foot, bearing plate means in the tube interposed between the elastomeric member and the lower end of the leg, and means attaching the tube to the lower end of the leg and permitting limited telescopic movement of the leg and the tube whereby said foot is adapted to move upwardly relative to the leg as the landing gear accepts the weight of the vehicle thereby resiliently to compress the elastomeric member between the foot and said bearing plate means.
