  • Patent number: 5503423
    Abstract: The invention relates to a swing away hitch for a trailer and method of making same. The hitch is intended to allow the trailer to be parked in a building only slightly longer than the boat itself. Boat trailer hitches extend beyond the bow of the boat by some distance, and thus these trailers require a shed longer than the actual boat. To correct this problem, a swing away hitch is installed proximate the boat. According to the present method, the tubular hitch is sandwiched between top and bottom plates. Holes through the hitch and the plates are aligned with one another and a tubular casing is inserted through the holes. Thereafter, the ends of the tubular casings are "swedged" or expanded by pressing bullet shaped pins into opposite ends of the casings. The swedging effect securely fastens the components. Finally, pins are inserted through the casings to mount the swing away hitch on the trailer.
