Claims
- 1. In a trailer landing gear assembly having a generally cylindrical housing and means for securing said housing to said trailer, a landing gear foot adapted to engage the ground and an extension assembly having a gear base plate received in said housing and a downwardly depending axle adapted to be received in two registering apertures in said foot, said gear base plate having an annular flange adjacent to the inner surface of said housing, the improvement comprising vertical load supporting means formed in said housing for connecting said extension assembly to said housing and for connecting said foot to said housing, said means comprising at least two upper and two lower inwardly projecting projections integral with said housing, wherein said upper projections are positioned on said housing to abut against the upper surface of said gear base plate flange and said lower projections abut against the lower surface of said gear base plate flange whereby said cylindrical portions and said projections support the vertical load of said landing gear assembly between the extension assembly and the landing gear housing..]. .[.2. The assembly as defined in claim 1 and in which said improvement further comprises a cylindrical portion integral with said landing gear foot and disposed around and coaxial with each of said apertures in said
- landing gear foot..]. .[.3. In a trailer landing gear assembly having a generally cylindrical housing and means for securing said housing to said trailer, a landing gear foot adapted to engage the ground and an extension assembly having a gear base plate received in said housing and a downwardly depending axle adapted to be received in two registering apertures in said foot, said gear base plate having an annular flange adjacent to the inner surface of said housing, means for constructing the load supporting attachment between said extension assembly and said landing gear foot and housing, comprising a cylindrical portion integral with said landing gear foot and disposed around and coaxial with each of said apertures in said landing gear foot and at least two upper and two lower inwardly projecting projections integral with said housing for abuttingly confining said annular flange in said housing, said cylindrical portions formed by stamping portions of said landing gear foot around said apertures outwardly..]. .[.4. The assembly as defined in claim 3 wherein said upper projections are positioned on said housing to abut against the upper surface of said gear base plate flange and said lower projections abut against the lower surface of said gear base plate flange whereby said projections support the vertical load of said landing gear assembly between the extension assembly and the landing gear housing..]. .Iadd. 5. In a trailer landing gear assembly having a tubular housing, means for securing said housing to said trailer, a landing gear foot adapted to engage the ground, and an extension assembly having a downwardly depending axle adapted to be received in two registering apertures in said foot, the improvement comprising vertical load supporting means comprising a pair of spaced apart wall members, each wall member comprising a substantially vertical central portion disposed parallel to the opposing central portion, and including one of said two registering apertures and a substantially vertical end portion aligned at each end of each central portion so as to intersect the plane of said central portion and secured to the end of said central portion to thereby provide lateral support to said central portion, and each said wall member further comprising a cylindrical portion integral and of unitary construction therewith formed by deforming a portion of said wall member around the periphery of its registering aperture to extend coaxially from one side of its registering aperture and further comprising a transversely extending support wall integrally connected at its ends to said pair of spaced apart wall members, said support wall being positioned below said apertures and running parallel to the axis of said aligned apertures. .Iaddend.
