  • Patent number: 5992871
    Abstract: This invention pertains to a swing-away hitch for trailers, in particular the boat trailer market. Boat trailers are longer than the boats itself for towing purposes. When having to store the boat and trailer in a small space, the tongue with the hitch of the trailer becomes an obstacle. This invention allows a trailer to be parked in spaces that could only hold the size of the boat by swinging the hitch to the side. The design of this invention consists of sandwiching a tube (tongue of the trailer) between two plates with holes that align with tubular sleeves welded on opposite sides at the end of a hitch cover to convert it to a swing-away hitch. Pins are inserted to mount the swing-away hitch onto the swing-away hitch assembly. In a towing position, both pins stay in their sleeves. In stowaway position, one pin is removed and the swing-away hitch swivels via the remaining pin away to the side of the trailer.
