An objective of the beach wagon is to provide users with a 3-in-1 outdoor accessory. In order to accomplish this, the beach wagon provides a multifunctional structure which can be utilized as a normal wagon as well as a beach chair. The beach umbrella configuration of the beach wagon further enables the attachment of an umbrella to provide a beach chair and umbrella combo. The structure of the beach wagon provides a foldable frame which can be configured into a wagon configuration or a chair configuration. Further, the foldable frame of the beach wagon enables easy and compact storage in the back of a vehicle. Additionally, the beach wagon is equipped with wide sand tires, and accommodates various secondary attachments such as cup holders, coolers etc. Furthermore, a modular wheel system of the beach wagon allows users to use different size and type of wheels.

An apparatus and methods for a convertible service and recycling cart for food and beverage service and waste sorting, compaction and storage are disclosed. An example cart apparatus includes a base, a first sidewall and a second sidewall each coupled to the base and a top support coupled to the first sidewall and the second sidewall. At least one opening is defined in the top support and a lid is removably coupled to the top support. The apparatus also includes at least one container that is configured to be removably coupled to the at least one opening in the top support.

A vehicle; the vehicle includes a receptacle, a door, at least one door-hinge, a right-ski, a left-ski, at least one right-hinge, and at least one left-hinge. The receptacle may be a container having four sides, a bottom, and an opening which is covered by the door. The door is hinged to the receptacle by the at least one door-hinge and may be opened or closed manually. The right hinges attach the right-ski to the receptacle, and the left hinges attach the left-ski to the receptacle. In this way, each ski may be folded up against the receptacle, or turned down to be deployed and used.

A sled transport apparatus for transporting people and supplies on sand and snow includes a sled body having a bow, a stern, a starboard side, a port side, a bottom, an upper perimeter, and a cavity. A divider wall is coupled to the sled body and extends from the starboard side to the port side and from the bottom to the upper perimeter. The divider wall forms a cooler receptacle within the cavity from the divider wall to the stern that is configured to receive a cooler. A seat bottom is coupled to the sled body adjacent the divider wall and extending from the starboard side to the port side and toward the bow. A towrope is coupled to the sled body.

This invention is directed to a kit of coolers that offers a number of improvements over the prior art. The coolers are modified to specifically accommodate frozen gel ice packs instead of ice cubes. Because there is no spill water, the coolers open with front-facing pull-out drawers. The coolers stack atop one another with interlocking parts. Easy transport is provided by a handle and wheels, which are attached to the bottom (main) bin. Internally, the cooler bins are compartmentalized horizontally or vertically with dividers. Hollow spaces within the walls and dividers of the bins accommodate frozen gel ice packs. Overall, the coolers are easier to pack and unpack, stack, load into a car, and transport on the ground than conventional ice chest coolers.

A mobile container that is designed to allows a user to easily transport the container through a variety of terrains, such as snow, sand, and pavement. The mobile container includes an insulated container, a first sled-molded runner, a second sled-molded runner, a first wheel, a second wheel, and a convex protrusion. The first sled-molded runner and the second sled-molded runner are positioned parallel and opposite to each other, across the insulated container, and are adjacently connected to a base of the insulated container. The first wheel and the second wheel are laterally and coaxially connected to the insulated container, opposite to each other. The convex protrusion modifies the flow of sand or snow about the insulated container in order to decrease drag. The convex protrusion is positioned opposite the first wheel and the second wheel. Additionally, the convex protrusion is integrated into a front surface of the insulated container.
