More Information
Summary:The coupling interconnects a trailer and a conventional hand-held two-wheeled cart. The coupling includes a frame to which a ball of a ball and socket joint is connected. The frame has a recess which is adapted to removably receive the forward portion of a lower plate of the cart. The coupling is connected to the cart by inserting the forward portion into the recess. The coupling is then positioned such that its ball is beneath the socket on the hitch of the trailer. When the cart is tipped backward, the ball rises and enters the socket and lifts the hitch thereby permitting the trailer to be moved by the cart.
