Abstract: A portable heating device includes an enclosed structure for containing and heating water. The firebox is constructed of steel and sits on four removable legs, allowing a campfire to burn on top of and underneath the firebox, maximizing heating elements. The heating of large quantities of water can be achieved by circulating water from a reservoir, through heat resistant hoses to the firebox, and then back into the reservoir once heated. This feature allows a hot tub for camping. A receptacle is placed in the upper firebox allowing a support post to be inserted, which supports a swivel arm or swivel grill for meal preparation. With the attachment of a steam diffuser, the portable heater can be used in combination with a sealable tent to become a sweat lodge. The device is also self-contained and easily transported by its conversion into a carrying case when not in use.

Abstract: A portable sink with warm and cold water supply. Two fluid containers with spigots are placed inside separate compartments of a metal frame, where one container is for hot water and the other container is for cold water. The metal frame underneath the hot water container is equipped with a propane burner and tank, and the entire metal frame rests on four legs. A basin or tub hangs below the spigots of the containers to act as a sink where clean running water may be unavailable. The frame also comes equipped with two side counters that fold down to provide extra space. The structure of the invention is equipped with detachable and/or foldable parts that fit together within the main unit of the metal frame thus forming a single self-supporting and self-containing unit.

Abstract: An exercise device for simulating jump roping and for providing a total body workout that is held and rotated in use, comprised of two units; each unit to be held in a hand of a user. The units each comprised of (1) a handle, (2) an elongated first element attached to the handle, and (3) the elongated element has at least a first loop. The units preferably include a loop forming device for forming a loop from a portion of the elongated first element. The loop forming device can be located inside or outside the handle. The units can include additional elongated elements or loops. In other preferred embodiments, the exercise units are comprised of: a handle, and an elongated first element attached to the handle, and the elongated element providing weight and air resistance during the rotation of the elongated first element.
