Claim 4

Hitch structure as claimed in claim 1, wherein said attaching means comprises irregularly shaped plate members projecting outwardly and downwardly from said side margins and configured to extend over said edges of the top into engagement with the body of the vehicle therebeneath, and a plurality of fasteners for securing said members to said body.

Claim 5

A stabilized towing vehicle and trailer combination comprisiNg: a wheeled towing vehicle having front and rear axles; a trailer provided with a primary, rear body section having a top and a bottom, a secondary, front body section spaced above the plane of said bottom and integral with the top portion of said primary section, and ground-engaging wheel units supporting said trailer and having a center axis extending transversely thereof, said secondary section presenting a forwardly extending nose defining a cavity therebeneath in front of said primary section into which the rear portion of said vehicle normally extends; ball and socket hitch means interconnecting the forward end of said nose and said vehicle, and constituting the sole connection between said vehicle and said trailer; said vehicle having a top presenting a zone thereon approximately midway front to rear and side to side, and structure securing said hitch means to said vehicle at said zone to substantially equalize the forces applied to the wheels of the vehicle, said structure attaching said hitch means to said vehicle top for 360* angular movement of the vehicle with respect to the trailer, said trailer having its weight distributed in said primary and secondary sections to locate the center of gravity of the entire trailer forwardly of the center of said primary section, said wheel units being disposed substantially at said center of gravity to cause the distance between said center axis of the wheel units and the rear axle of said vehicles to be no greater than approximately equal to the wheel base of the vehicle, said structure including a unitary, rigid baseplate overlying said top of the vehicle at said zone and extending thereacross from side to side, said baseplate having an elevated central portion and presenting downwardly sloping surfaces radiating from said central portion and facing in forward, rearward, and lateral directions, said hitch means having a pair of releasably interconnected components, one of said components being mounted on said central portion of the baseplate.

Claim 6

A stabilized towing vehicle and trailer combination comprisiNg: a wheeled towing vehicle having front and rear axles; a trailer provided with a primary, rear body section having a top and a bottom, a secondary, front body section spaced above the plane of said bottom and integral with the top portion of said primary section, and ground-engaging wheel units supporting said trailer and having a center axis extending transversely thereof, said secondary section presenting a forwardly extending nose defining a cavity therebeneath in front of said primary section into which the rear portion of said vehicle normally extends; ball and socket hitch means interconnecting the forward end of said nose and said vehicle, and constituting the sole connection between said vehicle and said trailer; said vehicle having a top presenting a zone thereon approximately midway front to rear and side to side, and structure securing said hitch means to said vehicle at said zone to substantially equalize the forces applied to the wheels of the vehicle, said structure attaching said hitch means to said vehicle top for 360* angular movement of the vehicle with respect to the trailer, said trailer having its weight distributed in said primary and secondary sections to locate the center of gravity of the entire trailer forwardly of the center of said primary section, said wheel units being disposed substantially at said center of gravity to cause the distance between said center axis of the wheel units and the rear axle of said vehicles to be no greater than approximately equal to the wheel base of the vehicle, said structure including a unitary, rigid baseplate overlying said top of the vehicle at said zone and extending thereacross from side to side, said baseplate having an elevated central portion and presenting downwardly sloping surfaces radiating from said central portion and facing in forward, rearward, and lateral directions, said hitch means having a pair of releasably interconnected components, one of said components being mounted on said central portion of the baseplate.

Claim 7

Hitch structure for connecting the tongue of a trailer to a towing vehicle having a top with side edges and doors with top edges, said structure comprising: a rigid baseplate adapted to overlie said vehicle top and extend laterally thereacross, said baseplate having an elevated central portion and opposed side margins adapted for disposition adjacent said side edges, means secured to said side margins for attaching said baseplate to said vehicle, said baseplate attaching means comprising a structural member sloping outwardly and downwardly and inwardly for disposition between said top side edges and said door top edges, means associated with said structural member for securing same to said vehicle between said top side edges and said door top edges, and a hitch component mounted on said central portion and adapted to be releasably connected with a mating hitch part carried by said tongue.

Claim 8

Hitch structure for connecting the tongue of a trailer to a towing vehicle having a top with side edges and doors with top edges, said structure comprising: a rigid baseplate adapted to overlie said vehicle top and extend laterally thereacross, said baseplate having an elevated central portion and opposed side margins adapted for disposition adjacent said side edges, means secured to said side margins for attaching said baseplate to said vehicle, said baseplate attaching means comprising a structural member sloping outwardly and downwardly and inwardly for disposition between said top side edges and said door top edges, means associated with said structural member for securing same to said vehicle between said top side edges and said door top edges, and a hitch component mounted on said central portion and adapted to be releasably connected with a mating hitch part carried by said tongue.

Claim 9

Hitch structure as set forth in claim 5, wherein said baseplate presents downwardly sloping surfaces radiating from said central portion and facing in generally forward, rearward and lateral directions.
