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.

The sleigh bed platform is intended for use in ice fishing for transport of equipment such as a tent shelter and sized to accommodate a single reclining person for rest on the ice. Sleigh bed invention is very light easy to pull across thin ice. Three laminated plastic layers with a inner component of expanded polystyrene form a rigid truss and thermal barrier that makes the sleigh bed a comfortable resting place. Expanded polystyrene is insulation and extremely buoyant providing a float in cases of breaking thru lake ice. Multiple soft rope handles secure loads with no sharp edges around the bed. A second invention use is for evacuation of injured skiers. Lightweight sleigh bed is easy to carry to an injured skier. A rigid front handle facilitates moving down hill with a passenger secured to the sleigh bed.

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 tunnel guard for a tunnel of a snowmobile has first and second arms. Each arm has a first end portion and a second end portion. The first end portions of the first and second arms have first and second connection elements respectively for connecting the first end portions of the arms to an interior of the tunnel. At least one member extends from at least one of the arms and is connected to the at least one of the arms. The at least one member has a third connection element for connecting the at least one member to the interior of the tunnel. The third connection element is disposed at a position that is one of: laterally between the first and second arms, and laterally outward of the first and second arms. A snowmobile having a tunnel guard and a method for connecting a tunnel guard are also disclosed.
