Patent ID: 8870251

Claim:
A hitch system for securing a second structure to a first structure, comprising: a first assembly mountable to the first structure, the first assembly comprising a plate attachable to the first structure in a substantially vertical orientation, a first side mount attached to said plate in an orientation substantially orthogonal to said plate so that the first side mount is substantially vertically oriented, a second side mount attached to said plate at a location on an opposed planar end of the plate relative to the location of the first side mount, in an orientation substantially orthogonal to said plate so that the second side mount is substantially vertically oriented and substantially parallel to the first side mount, a first pin extending substantially horizontally from an upper end of the first side mount toward the second side mount, a second pin extending substantially horizontally from an upper end of the second side mount toward the first side mount, and a hole disposed in the lower end of each of the first and second side mounts; a second assembly mountable to the second structure, the second assembly comprising a plate attachable to the second structure in a substantially vertical orientation, a first second assembly side mount attached to said second assembly plate in an orientation substantially orthogonal to said second assembly plate so that the first second assembly side mount is substantially vertically oriented, a second second assembly side mount attached to said second assembly plate at a location on an opposed planar end of the second assembly plate relative to the location of the first second assembly side mount, in an orientation substantially orthogonal to said second assembly plate so that the second second assembly side mount is substantially vertically oriented and substantially parallel to the first second assembly side mount, a first hook disposed on an upper end of said first second assembly side mount and a second hook disposed on an upper end of said second second assembly side mount, said second assembly further comprising a hole disposed in a lower end of each of said first and second second assembly side mounts; wherein when said first and second assemblies are engaged, to secure the second structure to the first structure, each of said first and second hooks are engaged with corresponding ones of each of said first and second pins to secure upper ends of the first and second assemblies together, and corresponding aligned holes of each of the first and second assemblies are joined together with a keeper pin to secure lower ends of the first and second assemblies together.
