ABSTRACT:
In a trailer landing gear assembly having a housing secured to a trailer and a foot adapted to engage the ground, attachment means for attaching an extension-retraction assembly to both the housing and the landing gear foot by respectively deforming the landing gear housing and the landing gear foot so that the deformations created support the axial load between the extension-retraction assembly and the landing gear. An axle secured to the downwardly depending end of the extension-retraction assembly is rotatably received in a pair of registering apertures formed in the landing gear foot. Each aperture in the landing gear foot is deformed to form a cylindrical portion coaxial with the aperture and integral with the foot so that the cylindrical portion supports the vertical load between the landing gear foot and the extension-retraction assembly. Similarly a gear base plate forms the attachment means between the upper end of the extension-retraction assembly and the landing gear housing. The gear base plate is received within the housing and includes a flange portion adjacent the interior of the housing. The housing is indented around the flange portion of the gear base plate so that the inward projections formed by the indentations overlap and secure the base plate flange portion to the housing. The projections then function to support the vertical load between the extension-retraction assembly and the landing gear housing.
