ABSTRACT:
A cart for transporting objects is provided. The cart includes a base structure supported on a plurality of wheels. An elongated tongue is telescopically mounted to an underside of the base structure and is movable between an extended position, wherein the tongue extends in front of the cart, and a retracted position, wherein the tongue is disposed under the cart. A hitch apparatus is mounted to the base structure at the posterior end thereof. The hitch apparatus includes a hitch for receiving a tongue of another cart and a locking assembly for locking the tongue to the hitch. The locking assembly includes a pin movable between locking and release positions. A tongue actuator is connected to the tongue and is operable, upon manipulation by an operator, to move the tongue from the retracted position to the extended position, while a hitch actuator is connected to the pin of the locking assembly and is operable, upon manipulation by an operator, to move the pin from the locking position to the release position. The tongue actuator is disposed toward one side of the cart and the hitch actuator is disposed toward one side of the cart. Both the tongue actuator and the hitch actuator are configured so as to be ergonomically accessible by an operator.
