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 lift assembly comprises a frame work extending between a first lift side and a second lift side and a frame support system wherein a portion of the frame support system includes a ski system that extends under the frame work in the direction of travel such that a continuous sliding surface is presented to slide the frame over obstacles.

Various embodiments of a snowmobile are disclosed. The lower arm is arranged below the upper arm. The lower arm includes proximal portions and connected to the ski support frame. The lower arm extends outwardly from the proximal portions and in the vehicle width direction and connects the ski support frame and the ski. The proximal portions and of the lower arm are positioned higher than the lower end of the engine. At least a portion of the lower arm is positioned higher than the rotational center of the crank shaft. This structure can prevent the center of gravity of the vehicle body from becoming high and reduce running resistance when the vehicle traveling in deep snow.

The present specification relates to a snowmobile. The upper arm includes two proximal portions connected to the vehicle frame and the upper arm extends outwardly from the two proximal portions in the vehicle width direction and the upper arm is connected to the knuckle. The two proximal portions are rotatable so that the knuckle and the skis can move up and down relative to the vehicle frame. The axis Ax2, passing through the rotation center C2 of the two proximal portions of the upper arm, goes through a position of the rotation center of the secondary shaft or through a position above the rotation center of the secondary shaft. This structure can reduce the force acting on the vehicle body frame via the upper arm and prevent an increase in the force.

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 Kneelboard device is for transporting a user across a surface, including handrail parts, runners and a multi-point harness attached together upon a user's kneeling legs, thighs, calves and/or hips, that are configured to be operable for generally maintaining balance and control. A plurality of side wall section(s), a seat portion, and one or more shin well segment(s), wherein the one or more shin well segment(s) are configured to provide a resting position for a user's legs, knees, shins and/or feet. One or more instep portion(s), wherein the one or more instep portion(s) are configured to provide a resting position for a user's instep. A raised back edge portion disposed at an end of the device's interior, and a plurality of underside edge section(s) where each underside edge section may considerably taper inward to allow for at least one of a controlled steering, deceleration and stopping.
