A temporarily attachable sled device for human-powered household vehicles includes a main body and at least one front end chock assembly and at least one rear end chock assembly. The main body is formed of a substantially waterproof sheet, with substantially at least the lower face of the sheet formed as a low friction surface. The at least one front end chock assembly and the at least one rear end chock assembly extending from the upper surface of the main body in use. The main body and the chock assemblies are sized and shaped so that a household vehicle can be positioned on the upper surface of the main body and prevented from riding up and over the chock assemblies. The main body includes ridges along and extending upwards from each side of the main body, the ridges extending substantially the length of the sides.

Quick-release skis couple to the front wheels of an ATV or other wheeled vehicle, to permit the ATV to travel over snow. The rear ATV wheels may be left unaltered, or more commonly, tracks may be substituted for the rear wheels. The ski coupling includes a drive-on runner and coupling having in one embodiment width-adjustable side walls, an over-center clamp, and a lock for securing the over-center clamp. In a second embodiment, a pivotal tire cage allows the ATV tire to be driven onto the ski, but simply by forward travel of the tire the cage pivots to constrain the tire thereon. A strap then binds the tire and cage to ensure the tire stays in place on the ski. In a third embodiment, an ATV track is converted to a runner by the application and tensioning of a ski. Additional embodiments are illustrated.

A cart ski system for urging a cart along a granular support surface includes a cart that may be rolled along a support surface. The cart has a set of rear wheels and a set of front wheels. A pair of skis is provided and each of the wheels is positioned in a corresponding one of the skis. Each of the skis slides along the support surface when the support surface is comprised of a granular material thereby enhancing urging the cart along the granular material.

A transportable fold-out structure includes a support frame. First and second primary platforms are pivotally supported by the support frame and each is disposed in an upright position wherein the platform extends upwardly. Two wall assemblies are disposed opposite each other. Each wall assembly includes a plurality of wall segments joined together. Each wall segment is pivotally joined to the support frame or one of the primary platforms. Each wall assembly is movable from a first position wherein the wall assembly is lying above the first and second primary platforms to a second position wherein the two wall assemblies face each other. First and second extensions are configured to be selectively positionable wherein a first portion of the extension is connected to the support frame and a second portion of the extension is remote from the corresponding first portion and extends laterally from the support frame.

A trailer includes at least a plurality of fabric support connections that retain a plurality of fabrics spaced apart from one another so as, if desired, to insulate the roof and side walls of the trailer. In one embodiment, the plurality of fabric support connections are connected by way of extrusions to some of the sides of the trailer and further provide insulation by forming a double wall on those sides. In another embodiment, the plurality of fabric support connections form a double wall only on certain portions of the top side of the trailer.
