ABSTRACT:
BACKGROUND OF THE INVENTION
Drinking water is commonly packaged and sold in large glass or plastic bottles having volume capacities of about five gallons. The containers are very bulky and heavy, weighing about 50 lbs. each.
Various two-wheeled hand trucks have been devised for carrying such bottled water containers. Co-pending U.S. patent application Ser. No. 08/812,935, which I incorporate herein by reference, discloses a two-wheeled hand truck having multiple, foldable bottle-carrying trays that are mounted to the side rails of the truck and extend forwardly over the nose plate in vertically spaced relation to one another for the accommodation of up to four such containers. When not in use, the trays are foldable flush with the rails so that the hand truck can be used in the usual manner to transport other types of cargo on the nose plate.
Other known hand truck constructions include single or multiple bottle-carrying racks carried off the frame that are either fixed or foldable, but not detachable from the frame of the truck.
SUMMARY OF THE INVENTION
One of the prime objects of the present invention is to provide a carrier for such bottled water containers that is mounted releasably to the frame of a two-wheeled hand truck to serve as the sole, or as an auxiliary, carrier for bottled water containers.
Another object of the invention is to construct the bottle carrier in such manner that it mounts on the frame of a two-wheeled hand truck without modification of the standard hand truck design. In particular, it is an object of the invention to construct such a carrier to include at least one, and preferably two, hangers that releasably engage the cross braces of the truck frame to support such a container outwardly of the frame.
It is a further object to construct a carrier that can be releasably selectively hung off either the front or back side of the frame. In an application employing a conventional hand truck, the carrier could be hung from the cross braces off the front side of the frame above the nose plate. In another application in which the carrier serves as an auxiliary support for an additional water bottle on a hand truck fitted with one or multiple bottle racks that project forwardly of the frame, such as in the case of the aforementioned hand truck with multiple, foldable bottle-carrying trays, the auxiliary carrier can be mounted detachably on the cross braces off the back of the hand truck frame to provide additional carrying capacity and counterbalance.
The mount hangers for the carrier uniquely cooperate with the vertically spaced cross braces in all instances to provide the results achieved.
