Abstract: A base plate is securable to a vehicle bumper using a threaded bolt attachment and supports a rectangular support which in turn is secured to and supports a planar top plate. A front plate is angularly positioned between the top plate and base plate to provide the combined support structure of a vehicle hitch securable to a vehicle bumper. A transversely extending saddle plate is spaced from the front plate at the lower edge thereof defining a lower channel therebetween. A pair of latch arms each defining respective notches therein are pivotally supported upon the vertical support and are coupled to a transversely extending angularly disposed cam plate. A return spring is operative to urge the latch arms to an upward locking position. An elongated handle is secured to one of the latch arms and extends downwardly therefrom. A pool cart or the like having an upper tube and lower tube is received within the latch arm notches and lower channel respectively to secure the pool cart to the vehicle hitch.

Abstract: A support mounting unit is provided for mounting a transportable cart or like apparatus to a vehicle so as to provide an easy method of transport for an apparatus. The mounting unit includes a mounting means for securing the invention to the rear bumper of a vehicle, a top and bottom clamping jaw for securing the cart to the mounting unit, and an automatic locking mechanism. The top jaw of the invention is attached to a main body portion by means of hinges on each side of the body portion. The top jaw can then be moved from a nominally horizontal closed position to an angled upwardly open position. Thus, once a lower attachment bar secured to the transportable apparatus has been placed in the lower U-shaped bracket, the apparatus is rotated and the upper attachment bar pushes the top jaw into the open position. The attachment bar can now be secured in the U-shaped bracket embedded in top jaw, and the top jaw can return to a closed position where the locking bolt automatically secures it.
