Abstract
Abstract A trailer hitch for use in pickups or similar vehicles includes a plate which is adapted to lie flush with the bed. The plate has a large aperture. A hitch block, which has a connecting ball at one end, is journaled on an axis below the plate in such a manner that, in the towing position, the ball is above the plate and, when the vehicle is used for hauling, the entire block can be folded down beneath the bed. The other end of the block is provided with a spring-urged retractable pin. An arcuate member beneath the plate has holes which receive the pin to hold the block in a selected position.
